Topical Administration of Teucrium polium on Diabetic Foot Ulcers Accelerates Healing: A Placebo-Controlled Randomized Clinical Study

Diabetic foot ulcer is one of the most devastating complications of uncontrolled diabetes. Although there have been advances in the management of diabetic foot ulcers, still diabetic foot ulcers are a major cause of many amputations in diabetic patients. Teucrium polium (T. polium) is widely used by folk medicine practitioners in Iran for the treatment of diabetic ulcers.The present study was designed to evaluate the safety and efficacy of topical T. polium ointment besides the standard treatment in diabetic foot ulcers.A total of 70 diabetic patients with foot ulcers grade 1 or 2 according to Wagner's scale were enrolled in this study. Patients were randomly divided into two groups. Patients in both groups received standard treatment for diabetic foot ulcers. In addition, group 1 received topical T. polium ointment, and group 2 received topical placebo ointment for 4 weeks. The T. polium and placebo ointments were rubbed twice daily two hours before the conventional dressing. The ulcer size, healing time, and laboratory tests were measured in both groups at baseline and end of the study after 4 weeks.Twenty-nine patients remained in the T. polium group and 26 in the placebo group until the end of the study. The mean surface area of ulcers was 3.52 ± 1.47 and 3.21 ± 1.67 cm2 in T. polium group and placebo group respectively at baseline which decrease to .717 ± .19 and 1.63 ± .72 cm2 respectively at the endpoint. The mean ulcer surface area was significantly lower in T. polium compared with the placebo group (p < .0001) at end of the study. Also, the number of patients that completely recovered in the T. polium group was significantly higher than the placebo group (p < .001) at the end of the study.The addition of topical T. polium ointment to standard treatment significantly improves the healing time of diabetic non-infected foot ulcers.

Efficacy of nano-modified Runji ointment in the treatment of mild and moderate psoriasis with blood dryness syndrome: a study protocol for a double-blind randomized controlled trial

INTRODUCTION

Psoriasis is a common, recurrent, immune skin disease, which seriously affects patients' quality of life. In clinical practice, modified Runji ointment can effectively treat mild-to-moderate psoriasis with blood dryness syndrome, but there is a lack of high-quality evidence-based medical evidence. This trial aims to evaluate the efficacy and safety of nano-modified Runji ointment in the treatment of mild-to-moderate psoriasis with blood dryness syndrome.

METHODS/DESIGN

This study will be a randomized double-blind placebo-controlled trial. A total of 80 patients will be recruited and randomly divided into an intervention group (nano-modified Runji ointment group) and a placebo group at a ratio of 1:1. All included patients will receive 8 weeks of nano-modified Runji ointment or placebo ointment respectively, twice a day. The primary outcome will be the change in psoriasis area and disease severity index score at week 8 compared to baseline. The secondary outcomes will be rash area score, pruritus score, Dermatology Life Quality Index score, traditional Chinese medicine symptom score and adverse events.

DISCUSSION

This study may provide high-quality evidence for the efficacy of nano-modified Runji ointment in the treatment of mild to moderate psoriasis with blood dryness syndrome. The results of this study will be published in peer-reviewed journals.

Comparative Evaluation of Efficacy and Safety of Tacrolimus and Dinoprostone Following Dermabrasion in Stable Vitiligo

BACKGROUND

Dinoprostone (DNP), a prostaglandin E2 (PGE2) analogue, has been found to cause repigmenation in vitiliginous lesions. Combined medical and surgical therapy might be more useful for successful treatment of vitiligo.

OBJECTIVES

In this study, we aimed to evaluate the efficacy and safety of dermabrasion followed by dinoprostone gel and to compare it with tacrolimus ointment following the same procedure in the treatment of localized stable vitiligo.

METHODS

40 patients of stable vitiligo were enrolled which were divided in two groups of 20 patients each. In group 1, dermabrasion followed by tacrolimus 0.1% ointment was done and in group 2, dermabrasion followed by dinoprostone gel was done.

RESULTS

Group 1 patients showed slightly better response (P=0.039), whereas the side effect profile was better for group 2.

CONCLUSION

DNP and tacrolimus have immunomodulatory and melanocyte stimulating effect and are well tolerated when combined with dermabrasion. Their effect on skin pigmentation could be enhanced by dermabrasion. J Drugs Dermatol. 2021;20(5):519-522. doi:10.36849/JDD.5751.

Carboxytherapy Mask as Post Nanofractional Radiofrequency Treatment for Improvement of Facial Skin Quality and Photoaging

BACKGROUND

Skin rejuvenation can be achieved with minimally invasive treatments using energy-based devices that feature reduced side effects and downtime. Post-treatment care is key to minimize any potential side effects and skin reactions such as erythema, dryness, or dyschromia.

OBJECTIVE

The objective of this study was to evaluate the efficacy and patient satisfaction of a novel carboxytherapy gel mask compared with petroleum-based lanolin-containing ointment to accelerate wound healing facial post-nanofractional radiofrequency treatment.

METHODS AND MATERIALS

Ten subjects were enrolled in this pilot, prospective, randomized, single-blind study and randomized into two arms. One arm received one nanofractional radiofrequency treatment with ointment right after and four consecutive days of ointment applications twice a day, while the second arm followed this regimen with a carboxytherapy gel mask application right after and four consecutive days after treatment. Investigator, safety, and patient assessments were conducted at 24 hours and one-week post treatment. Safety was monitored throughout. The primary endpoint was defined as the degree of investigator global assessment (IGA) in photodamage, pigmentation, and wrinkles using standardized photographs. Secondary endpoints included investigator-rated degree of erythema, edema, crusting, exudation, percentage healing, improvement of skin quality, and patient satisfaction.

RESULTS

Nine patients completed the study. There was improvement of one degree in IGA for photodamage, pigmentation and wrinkles in all patients using the carboxytherapy gel mask at the one-week follow up. Blinded investigator ratings showed significant improvement of dryness, erythema, edema, crusting, and percentage healing at the 24-hour follow up, with all patients remaining the same a week post treatment. All patients in the carboxytherapy group were satisfied with the treatment and had no adverse effects. Three patients in the petroleum-based lanolin-containing group experienced mild edema and acne breakout that resolved two weeks after treatment.

CONCLUSION

Carboxytherapy delivered via a gel mask after skin rejuvenation procedures is a safe and effective strategy to improve clinical outcomes and reduce post-treatment side effects. J Drugs Dermatol. 20(4):461-465. doi:10.36849/JDD.5856.

Efficacy and safety of Soshiho-tang in atopic dermatitis patients with gastrointestinal disorders: A double-blinded, randomized, and placebo-controlled clinical trial

ETHNOPHARMACOLOGICAL RELEVANCE

Because of the growing incidence of AD, psychosocial and economic burden of AD patients are often considerable. Steroid treatments are widely used, but long term use of this treatment can cause side effects. To reduce the burden of AD patients and find new efficient treatment, this study chose Soshiho-tang, a traditional medicine used in eastern Asia.

AIM OF THE STUDY

Soshiho-tang (SSHT) is a traditional herbal medicine that has anti-inflammatory effects and improves immune function. This clinical trial evaluated the efficacy and safety of SSHT in atopic dermatitis (AD) patients with gastrointestinal disorders in comparison with placebo.

MATERIALS AND METHODS

This study was a single-center, randomized, double-blinded, placebo-controlled, and investigator-initiated clinical trial. A total of 60 patients aged 3-18 years with gastrointestinal disorders and diagnosed with AD by Hanifin & Rajka criteria with a Scoring Atopic Dermatitis (SCORAD) index between 15 and 49 were enrolled. Participants were randomly assigned to the SSHT or placebo groups in a ratio of 1:1 and efficacy evaluation was conducted at week 4 and 8. The participants orally administered SSHT or placebo three times a day for 4 weeks. The primary outcome was measured based on a change of SCORAD index. The secondary outcome measurements included the following: survey questionnaires of gastrointestinal disorder, amount and frequency of ointment application for AD, dermatology quality of life index, and safety evaluation (diagnostic test, adverse reaction, and vital sign monitoring).

RESULTS

During efficacy evaluation, the SCORAD score and digestive symptoms in the experimental and placebo groups were not statistically significant. However, the amount and frequency of ointment application in the experimental group were reduced compared to those in the placebo group at week 8. Also, In the Children's Dermatology Life Quality Index (CDLQI), statistically significant Quality of Life (QOL) improvement was observed in the SSHT experimental group compared to the placebo group. In safety evaluation, all participants were within the normal range during the study period. Blood sample testing indicated that the lymphocytes ratio decreased, and neutrophils ratio increased in the experimental group, whereas the placebo group showed the opposite immune response pattern.

CONCLUSION

We concluded that SSHT administration can reduce steroid ointment dependence and improve the QOL in AD patients by regulating neutrophil-lymphocyte ratio.

Sinecatechins ointment as a potential novel treatment for usual type vulval intraepithelial neoplasia: a single-centre double-blind randomised control study

OBJECTIVE

To compare the safety and efficacy of 10% sinecatechins (Veregen® ) ointment against placebo in the treatment of usual type vulvar intraepithelial neoplasia (uVIN).

DESIGN

A Phase II double-blind randomised control trial.

SETTING

A tertiary gynaecological oncology referral centre.

POPULATION

All women diagnosed with primary and recurrent uVIN.

METHODS

Eligible patients were randomised 1:1 to receive either sinecatechins or placebo ointment (applied three times daily for 16 weeks) and were followed up at 2, 4, 8, 16, 32 and 52 weeks.

MAIN OUTCOME MEASURES

The primary outcome measure, recorded at 16 and 32 weeks, was histological response (HR). Secondary outcome measures included clinical (CR) response, toxicity, quality of life and pain scores.

RESULTS

There was no observed difference in HR between the two arms. However, of the 26 patients who were randomised, all 13 patients who received sinecatechins showed either complete (n = 5) or partial (n = 8) CR, when best CR was evaluated. In placebo group, three patients had complete CR, two had partial CR, six had stable disease and two were lost to follow up. Patients in the sinecatechins group showed a statistically significant improvement in best observed CR as compared with the placebo group (P = 0.002). There was no difference in toxicity reported in either group.

CONCLUSION

Although we did not observe a difference in HR between the two treatment arms, we found that 10% sinecatechins application is safe and shows promise in inducing clinical resolution of uVIN lesions and symptom improvement, thus warranting further investigation in a larger multicentre study.

TWEETABLE ABSTRACT

A randomised control study indicating that sinecatechins ointment may be a novel treatment for uVIN.

A Retrospective Study of Corneal Endothelial Dystrophy in Dogs (1991-2014)

PURPOSE

To retrospectively evaluate the clinical data, diagnostic tests, treatments, and outcomes for dogs with corneal endothelial dystrophy (CED) and determine risk factors for CED when compared with a canine reference population.

METHODS

Medical records of 99 dogs (1991-2014) diagnosed with CED at the University of California Davis Veterinary Medical Teaching Hospital were reviewed and compared with 458,680 dogs comprising the general hospital population during the study period. Retrieved data included signalment, examination findings, diagnoses, treatments, and outcomes associated with CED. The exact Pearson χ2 test or exact Kruskal-Wallis test was used to compare parameters between the groups. Progression of corneal edema was assessed using 3 independent Kaplan-Meier curves, identifying clinically significant changes in corneal opacity.

RESULTS

Boston terriers, German wirehaired pointers, and Dachshunds were overrepresented in the CED-affected group, whereas Labradors were underrepresented. Dogs older than 11 years were overrepresented in the CED-affected group, whereas intact dogs were underrepresented. Surgical intervention was performed (n = 11) based on the severity of disease and secondary complications from CED. Median time to progression of corneal edema was 1) 368 days when an at-risk eye initially without edema developed edema at a subsequent visit, 2) 701 days when there was progression from mild to marked corneal edema, and 3) 340 days when there was progression from focal to diffuse corneal edema.

CONCLUSIONS

Many CED-affected dogs progress over months to years without surgical intervention, making dogs with CED a useful model for studying genetic predispositions and development of novel therapeutics for Fuchs endothelial corneal dystrophy.

Efficacy and safety of Hemoheal cream in patients with hemorrhoids: a randomized double-blind placebo controlled clinical trial

OBJECTIVE

To evaluate the efficacy and safety of Hemoheal cream, an anti-hemorrhoid herbal preparation, (inspired by Persian medicine literatures in a double-blind, randomized placebo-controlled trial.

METHODS

Hemoheal cream consists of aqueous extract of Allium ampeloprasum L., Commiphora mukul (Hook. Ex Stocks) Engl and the oil of Sesamum indicum L. Fifty-two patients with symptomatic hemorrhoids were randomized to receive hemoheal cream or placebo for 3 weeks. The patients were evaluated before and after the intervention in terms of the severity of anal irritation, bleeding, anal itching, pain, defecation discomfort and swelling sense, and overall subjective improvement (%), as well as any reported adverse events.

RESULTS

The results showed that after 3 weeks of treatment, distribution of anal irritation, bleeding, pain as well as swelling sense were significantly different (P < 0.05), while the analysis showed no significant differences between two groups for anal itching and defecation discomfort (P > 0.05). Furthermore, a significant difference was observed between the overall subjective improvement of Hemoheal cream and placebo groups (P = 0.012). One patient in the treatment group complained of rashes on the application site.

CONCLUSION

The present study showed a positive effect of Hemoheal cream in improving clinical signs and symptoms in patients with hemorrhoids.

Surgical Sphincter Saving Approach and Topical Nifedipine for Chronic Anal Fissure with Hypertonic Internal Anal Sphincter

PURPOSE

The role of augmented internal anal sphincter (IAS) tone in the genesis of posterior chronic anal fissure (CAPF) is still unknown. Lateral internal sphincterotomy is the most employed surgical procedure, nevertheless it is burdened by high risk post-operative anal incontinence. The aim of our study is to evaluate results of sphincter saving procedure with post-operative pharmacological sphincterotomy for patients affected by CAPF with IAS hypertonia. Methods: We enrolled 30 patients, undergone fissurectomy and anoplasty with V-Y cutaneous flap advancement; all patients received topical administration of nifedipine 0.3% and lidocaine 1.5% ointment-based therapy before and for 15 days after surgery. The primary goal was patient's complete healing and the evaluation of incontinence and recurrence rate; the secondary goal included the evaluation of manometry parameters, symptom relief and complications related to nifedipine and lidocaine administration. Results: All wounds healed within 40 days after surgery. We didn't observe any de novo postoperative anal incontinence case. We reported 2 cases of recurrences, healed after conservative therapy. We didn't report any local complications related to the administration of the ointment therapy; with whom all patients reported a good compliance. Conclusions: Fissurectomy and anoplasty with V-Y cutaneous advancement flap and topical administration of nifedipine and lidocaine, is an effective treatment for CAPF with IAS hypertonia.

Impact of sildenafil-containing ointment on wound healing in healthy and experimental diabetic rats

AIM

The study evaluated the effect of different concentrations of sildenafil-containing ointment on wound healing in healthy and streptozotocin (STZ)-induced diabetic rats.

METHODS

A total of 108 Sprague Dawley male rats aged 5 months were randomly divided into two groups: healthy and diabetes-inducing rats. Following induction of diabetes by intraperitoneal STZ injection (55 mg/kg), diabetic and healthy rats were subdivided into six groups (9 rats each). Linear incisions of the dorsal backs of rats were made. Then, rats were treated twice daily with either 2%, 2% + Fucidin, 5% sildenafil-containing ointments, oral sildenafil (13.0 mg/kg), moist exposed burn ointment or vehicle. During treatment, the percent reduction of the wound area and tensile strength were measured on days 3, 7 and 10. Furthermore, histopathology was performed on the wounded skin on similar days for the assessment of collagen synthesis and proliferation of new capillary vessels.

RESULTS

In healthy and STZ-induced diabetic rats, the percent reduction in wound area on day 3 was significantly higher in sildenafil-containing ointment-treated groups than all other groups, whereas on day 7 only the 5% sildenafil-containing ointment-treated group showed better response in healthy rats. Although the sildenafil-containing ointment significantly showed better tensile strength than all other groups, the 5% sildenafil-treated group significantly enhanced the tensile better than the 2% and 2% + Fucidin dose. Furthermore, the histological evaluation revealed that sildenafil-containing ointment promoted collagen synthesis and proliferation of new capillary vessels.

CONCLUSION

Our results suggest that sildenafil-containing ointment can provide an advantage in wound healing by promoting wound contractions and resistance to wound breakage in healthy and diabetic conditions. Therefore, 5% sildenafil-containing ointment can be used as a support factor for wound healing in healthy and diabetic conditions; however, clinical trials are required to confirm the benefits of sildenafil in wound healing.

Sulfated polysaccharide ascophyllan from Padina tetrastromatica enhances healing of burn wounds by ameliorating inflammatory responses and oxidative damage

Sulfated polysaccharide ascophyllan from marine brown algae has been identified to have burn wound healing properties. Thus, we examined the effects of ascophyllan fraction (AF3) on the inflammatory response and oxidative damage in burn wounds. Full-thickness burn wounds in rats were then treated twice per day with topical AF3 ointment (5%), while control groups were treated with 10% povidone-iodine (positive control) and petroleum jelly-based ointment (negative control). The activity of cyclooxygenase-2 and myeloperoxidase and levels of C-reactive protein, nitric oxide, and proinflammatory cytokines (tumor necrosis factor-α, interleukin-6, and interleukin-1β) were observed to have significantly decreased in peripheral blood mononuclear cells, serum, and wound tissue of the group treated with AF3 ointment on day 8 after wounding. The expression of inducible nitric oxide synthase, endothelial nitric oxide synthase, and vascular endothelial growth factor at the mRNA level was determined to be upregulated in the wound tissue of the AF3 ointment-treated group. After treatment with AF3 ointment, the antioxidant enzyme activity and level of reduced glutathione were upregulated, whereas the content of thiobarbituric acid reactive substances decreased. Treatment of burn wounds using 5% AF3 ointment decreases oxidative damage associated with inflammation deceptively via inhibition of inflammatory enzymes, regulation of proinflammatory cytokines, upregulation of angiogenesis, and activity of antioxidant enzymes.

Interventions for preventing mastitis after childbirth

BACKGROUND

Despite the health benefits of breastfeeding, initiation and duration rates continue to fall short of international guidelines. Many factors influence a woman's decision to wean; the main reason cited for weaning is associated with lactation complications, such as mastitis. Mastitis is an inflammation of the breast, with or without infection. It can be viewed as a continuum of disease, from non-infective inflammation of the breast to infection that may lead to abscess formation.

OBJECTIVES

To assess the effectiveness of preventive strategies (for example, breastfeeding education, pharmacological treatments and alternative therapies) on the occurrence or recurrence of non-infective or infective mastitis in breastfeeding women post-childbirth.

SEARCH METHODS

We searched Cochrane Pregnancy and Childbirth's Trials Register, ClinicalTrials.gov, the WHO International Clinical Trials Registry Platform (ICTRP) (3 October 2019), and reference lists of retrieved studies.

SELECTION CRITERIA

We included randomised controlled trials of interventions for preventing mastitis in postpartum breastfeeding women. Quasi-randomised controlled trials and trials reported only in abstract form were eligible. We attempted to contact the authors to obtain any unpublished results, wherever possible.  Interventions for preventing mastitis may include: probiotics, specialist breastfeeding advice and holistic approaches.   DATA COLLECTION AND ANALYSIS: Two review authors independently assessed trials for inclusion and risk of bias, extracted data and assessed the certainty of the evidence using GRADE.

MAIN RESULTS

We included 10 trials (3034 women). Nine trials (2395 women) contributed data. Generally, the trials were at low risk of bias in most domains but some were high risk for blinding, attrition bias, and selective reporting. Selection bias (allocation concealment) was generally unclear. The certainty of evidence was downgraded due to risk of bias and to imprecision (low numbers of women participating in the trials). Conflicts of interest on the part of trial authors, and the involvement of industry funders may also have had an impact on the certainty of the evidence. Most trials reported our primary outcome of incidence of mastitis but there were almost no data relating to adverse effects, breast pain, duration of breastfeeding, nipple damage, breast abscess or recurrence of mastitis. Probiotics versus placebo Probiotics may reduce the risk of mastitis more than placebo (risk ratio (RR) 0.51, 95% confidence interval (CI) 0.35 to 0.75; 2 trials; 399 women; low-certainty evidence). It is uncertain if probiotics reduce the risk of breast pain or nipple damage because the certainty of evidence is very low. Results for the biggest of these trials (639 women) are currently unavailable due to a contractual agreement between the probiotics supplier and the trialists. Adverse effects were reported in one trial, where no woman in either group experienced any adverse effects. Antibiotics versus placebo or usual care The risk of mastitis may be similar between antibiotics and usual care or placebo (RR 0.37, 95% CI 0.10 to 1.34; 3 trials; 429 women; low-certainty evidence). The risk of mastitis may be similar between antibiotics and fusidic acid ointment (RR 0.22, 95% CI 0.03 to 1.81; 1 trial; 36 women; low-certainty evidence) or mupirocin ointment (RR 0.44, 95% CI 0.05 to 3.89; 1 trial; 44 women; low-certainty evidence) but we are uncertain due to the wide CIs. None of the trials reported adverse effects. Topical treatments versus breastfeeding advice The risk of mastitis may be similar between fusidic acid ointment and breastfeeding advice (RR 0.77, 95% CI 0.27 to 2.22; 1 trial; 40 women; low-certainty evidence) and mupirocin ointment and breastfeeding advice (RR 0.39, 95% CI 0.12 to 1.35; 1 trial; 48 women; low-certainty evidence) but we are uncertain due to the wide CIs. One trial (42 women) compared topical treatments to each other. The risk of mastitis may be similar between fusidic acid and mupirocin (RR 0.51, 95% CI 0.13 to 2.00; low-certainty evidence) but we are uncertain due to the wide CIs. Adverse events were not reported. Specialist breastfeeding education versus usual care The risk of mastitis (RR 0.93, 95% CI 0.17 to 4.95; 1 trial; 203 women; low-certainty evidence) and breast pain (RR 0.93, 95% CI 0.36 to 2.37; 1 trial; 203 women; low-certainty evidence) may be similar but we are uncertain due to the wide CIs. Adverse events were not reported. Anti-secretory factor-inducing cereal versus standard cereal The risk of mastitis (RR 0.24, 95% CI 0.03 to 1.72; 1 trial; 29 women; low-certainty evidence) and recurrence of mastitis (RR 0.39, 95% CI 0.03 to 4.57; 1 trial; 7 women; low-certainty evidence) may be similar but we are uncertain due to the wide CIs. Adverse events were not reported. Acupoint massage versus routine care Acupoint massage probably reduces the risk of mastitis compared to routine care (RR 0.38, 95% CI 0.19 to 0.78;1 trial; 400 women; moderate-certainty evidence) and breast pain (RR 0.13, 95% CI 0.07 to 0.23; 1 trial; 400 women; moderate-certainty evidence). Adverse events were not reported. Breast massage and low frequency pulse treatment versus routine care Breast massage and low frequency pulse treatment may reduce risk of mastitis (RR 0.03, 95% CI 0.00 to 0.21; 1 trial; 300 women; low-certainty evidence). Adverse events were not reported.

AUTHORS' CONCLUSIONS

There is some evidence that acupoint massage is probably better than routine care, probiotics may be better than placebo, and breast massage and low frequency pulse treatment may be better than routine care for preventing mastitis. However, it is important to note that we are aware of at least one large trial investigating probiotics whose results have not been made public, therefore, the evidence presented here is incomplete. The available evidence regarding other interventions, including breastfeeding education, pharmacological treatments and alternative therapies, suggests these may be little better than routine care for preventing mastitis but our conclusions are uncertain due to the low certainty of the evidence. Future trials should recruit sufficiently large numbers of women in order to detect clinically important differences between interventions and results of future trials should be made publicly available.

Feasibility Study of Asthma Cream

Asthma, which affects nearly 1 in every 12 people, is a large problem in the U.S. Asthma results in a cost of $56 billion dollars in various hospital bills and inconveniences. Many treatments of asthma use delivery methods (e.g., inhalers, tablets, capsules) that cannot be used by many patients if they have medical conditions that weaken their ability to inhale or swallow. This study's purpose was to examine the use of topically applied creams as a potential alternative to the use of conventional asthma medications. To test if a cream could work to treat asthma, a cream was developed with a drug normally taken orally that was combined with a cream base that was found most suitable to deliver the drug. The cream was then tested in-situ with mice as the test subject. The cream was applied to the backs of four groups of three mice for 0.5 hours, 1.5 hours, 5 hours, and 7 hours. Blood samples were taken after the respective times, and the quantity of the drug was analyzed in a mass spectrometer. The results showed that a cream delivered enough of an asthma drug to match the bioavailability of an average adult taking montelukast sodium. With this new delivery method, a cream can be used to treat asthma, which can also relieve the discomfort of asthma patients who are unable to use inhaled drugs and even possibly save lives of those unable to use traditional methods of delivery.

Relief of hemorrhoid symptoms: pilot study of a new topical ally

AIM

The pathogenesis of hemorrhoids involves vascular congestion, fragmentation of supporting tissues and, in many cases, increased resting anal pressure. A new ointment (Hemolen®) has been devised to control hemorrhoids symptoms acting on all the pathophysiologic mechanisms involved.

METHODS

Pilot study on patients with grade I-III hemorrhoids. The ointment was applied twice daily for 30 days and follow-up visits were scheduled 7 days (T1), 14 days (T2) and 30 days (T3) after recruitment (T0). Signs and symptoms (bleeding, discomfort, itching, edema, thrombosis, congestion, inflammation, pain) were evaluated at each visit using dedicated scores and VAS scale. Resting anal pressure was measured at time T0, 1 hour after the first application and at T1. Use of painkiller was recorded.

RESULTS

48 patients (25 females; mean age 47±15.8 years) were enrolled; 52.1% of them had II degree hemorrhoids and 27.1% had III degree hemorrhoids. The severity scores significantly dropped from T0 to each scheduled visit and a significant reduction of resting anal pressure was observed from T0 to 1 hour after application (z=13.5; p<0.001) and from T0 to T1 (z=6; p<0.001). The comparison of the resting pressure among whole time series showed a significant reduction (Fr=124.4; p=<0.001). Use of pain-killers decreased significantly from T0 to T1 (p<0.001) and from T1 to T2 (p=0.001).

CONCLUSION

The new ointment tested in the present study is safe and effective for the management of hemorrhoid symptoms in the early stages hemorrhoids, during the acute phases and in patients with more severe hemorrhoids awaiting surgery. Prospective, randomized controlled trials are needed to confirm these encouraging results.

Formulation, characterization and in vivo evaluation of Hedera helix L., topical dosage forms

The purpose of this study was to prepare topical formulations of micro emulsion, gel and ointment containing the Hedera helix L. extracts against asthma and to evaluate the physicochemical characteristics. A validated HPLC method was used for the analysis of blood plasma. In-vivo studies of the drugs were compared in rabbit plasma with oral dosing. Stability studies were performed for 3 months. The results showed that formulations were stable. No Skin irritation observed on rabbits. The optimized micro emulsion and gel showed fast absorption. Maximal plasma concentration (c_max) and the maximal time to reach cmax (tmax) were 70.226μg/mL, 75.26μg/mL and 2 hours for the micro emulsion and gel, 90.11μg/mL and 1 hour for the oral drug syrup respectively. Pharmacokinetic parameters such as t_max, c_max and AUC of the selected formulations and oral dosing were significantly different (P < 0.01).

[Adequate prescription and application of topicals : How to calculate the right volume for the prescription of ointment needed?]

BACKGROUND

Uncertainty regarding the suitable amount of prescribed ointment and its application by patients may cause insufficient or uneconomic health care provision. To address this issue, standardized methods and experts' knowledge on the suitable amount and coherent patient's elucidation for application of topicals are needed.

OBJECTIVES

Presented are current data in routine care and scientific evidence on the prescribed amount of topical agents as well as its application by patients in dermatological care.

MATERIALS AND METHODS

A literature review was conducted via PubMed using the keywords as individual and pooled search terms: "local therapy", "topical treatment", "prescription", "amount of ointment needed", "involved area", "BSA", "finger-tip-unit", "Rule of Hand", "calculated dosage" and "rule of nines". We included original studies by manually screening title and abstract according to the relevance of the topic.

RESULTS

The search strategy identified 19 clinical trials. The fingertip unit (FTU) is the most frequently used measurement for accurate application of external agents. Appropriate prescribed amount is calculated by required topical agent per involved surface area.

CONCLUSIONS

There is still a need for clarification to which extent the optimized amount of ointment is prescribed and advice for its application in routine care is given. The FTU combined with the "Rule of Hand" is an adequate measurement for patient's guidance on self-application.

Evaluation of the bacterial ocular surface microbiome in clinically normal cats before and after treatment with topical erythromycin

The ocular surface microbiome of veterinary species has not been thoroughly characterized using next generation sequencing. Furthermore, alterations in the feline ocular surface microbiome over time or following topical antibiotic treatment are unknown. Aims of this study were to further characterize the ocular surface microbiome of healthy cats and to identify whether there are microbial community changes over time and following topical antibiotic use. Twenty-four eyes from twelve adult, research-bred, female spayed domestic shorthaired cats were evaluated. Erythromycin ophthalmic ointment (0.5%) was applied to the ocular surface of one randomly assigned eye per cat three times daily for 7 days, while the fellow eye served as an untreated control. The ocular surface was sampled by swabbing the inferior conjunctival fornix of both eyes prior to initiating treatment (day 0), after 1 week of treatment (day 7), and 4 weeks after concluding treatment (day 35). Genomic DNA was extracted from the swabs and sequenced using primers that target the V4 region of bacterial 16S rRNA genes. At baseline, the most common bacterial phyla identified were Proteobacteria (42.4%), Firmicutes (30.0%), Actinobacteria (15.6%), and Bacteroidetes (8.1%). The most abundant bacterial families sequenced were Corynebacteriaceae (7.8%), Helicobacteraceae (7.5%), Moraxellaceae (6.1%), and Comamonadaceae (5.6%). Alpha and beta diversity measurements were largely unchanged in both treatment and control eyes over time. However, univariate and linear discriminant analyses revealed significant and similar changes in the abundance of some bacterial taxa over time in both treatment and control eyes. Overall, the feline ocular surface microbiome remained stable over time and following topical antibiotic therapy.

In vitro and ex-vivo evaluation of topical formulations designed to minimize transdermal absorption of Vitamin K1

Topical application of Vitamin K1 has been demonstrated to effectively treat papulopustular skin rash, a serious and frequently encountered side effect of Epidermal Growth Factor Inhibitors (EGFRIs). Systemic absorption of vitamin K1 from skin and the resultant consequence of antagonizing EGFRIs anticancer effects jeopardizes the clinical acceptability of this rather effective treatment. The purpose of the present study was to rationally formulate and evaluate the release rate and transdermal absorption of a wide range of Vitamin K1 dermal preparations with a variety of physiochemical properties. A library of 33 formulations with were compounded and tested for Vitamin K1 permeation using hydrophobic membranes and porcine skin mounted in a Fran diffusion cells. Our results demonstrate the lowest diffusion for water-in-oil emulsions, which also demonstrated a negligible transdermal absorption. The statistical analysis showed a significant correlation between in vitro and ex vivo results. While viscosity did not have a significant impact on the diffusion or absorption of vitamin K1, an increase in the lipid content was correlated with an increase in transmembrane diffusion (not with transdermal absorption). Overall, formulation design significantly impacts the release rate and transdermal absorption of vitamin K1, and confirms the possibility of minimal systemic distribution of this vitamin for this specific purpose.

Application of conjugated estrogen cream in the treatment of postmenopausal atrophic vaginitis

To observe and analyze the effect of conjugated estrogen cream in the treatment of postmenopausal atrophic vaginitis. The 160 patients clearly diagnosed with postmenopausal atrophic vaginitis and treated in our hospital were selected as subjects and divided into study group and reference group with equal number of cases. The reference group was treated with compound metronidazole suppository, while the study group was treated with conjugated estrogen cream. The treatment efficacy of the two groups was compared and observed. Comparison of estradiol and folliclestimulating hormone levels after treatment in the two groups show that the study group has obvious advantage over the reference group, p<0.05; comparison of vagina cleanliness in the two groups after treatment shows the study group is significantly superior to the reference group, p<0.05; comparison of incidence of adverse reactions in the two groups shows that the study group has lower incidence, with statistical significance in comparison between the groups, p<0.05. Treatment of postmenopausal atrophic vaginitis with combination of conjugated estrogen cream and compound metronidazole suppository can achieve good results with high safety and reliability.

Considerations for Systemic and Topical Treatment of Morganella morganii Septicemia Arising from Maggot Infestation

INTRODUCTION

Live maggot infestation (myiasis) of wounds can present a host of ailments. Loosely associated with maggot excreta, Morganella morganii is a widespread, gram-negative rod bacterium commonly found in the intestinal tracts of humans. M morganii has been observed as being pathogenic, particularly in nosocomial and postoperative environments, as well as in immunosuppressed and elderly populations.

CASE REPORT

Herein, the authors present a rare, previously unreported case of M morganii septicemia (as confirmed by positive blood culture), secondary to myiasis of the lower extremities. The patient was successfully treated with both systemic and topical interventions. Posttreatment examination revealed resolution of myiasis and negative blood cultures.

CONCLUSIONS

Myiasis can be invasive, leading to severe systemic infection. In these cases, a broad-spectrum antibiotic combined with systemic and topical antiparasitic therapy should be considered.

Topical Agents for Scar Management: Are They Effective?

Scar formation is the body's natural healing response to reestablish dermal integrity following an injury. Excessive scarring, however, can cause significant cosmetic, functional, and psychological problems. A wide variety of topical creams, lotions, and oils are available for scar treatment or wound healing. Sieving through the options and selecting the best option for their patients can be challenging for clinicians, especially given that clinical evidence for many of the active agents in commonly used topical treatments is lacking. The goal of this review is to provide an overview of topical treatments utilized for scar management, including their mechanism of action and evidence of efficacy. As knowledge of the wound healing process is critical to understanding the effects of topical treatments, the pathophysiology of wound healing is also reviewed. <p><em>J Drugs Dermatol. 2018;17(4):421-425.</em></p>.

Clostridial collagenase ointment and medicinal honey utilization for pressure ulcers in US hospitals

AIMS

To describe the utilization of clostridial collagenase ointment (CCO) and medicinal honey debridement methods in real-world inpatient and outpatient hospital settings among pressure ulcer (PU) patients and compare the frequency of healthcare re-encounters between CCO- and medicinal honey-treated patients.

MATERIALS AND METHODS

De-identified hospital discharge records for patients receiving CCO or medicinal honey methods of debridement and having an ICD-9 code for PU were extracted from the US Premier Healthcare Database. Multivariable analysis was used to compare the frequency of inpatient and outpatient revisits up to 6 months after an index encounter for CCO- vs medicinal honey-treated PUs.

RESULTS

The study identified 48,267 inpatients and 2,599 outpatients with PUs treated with CCO or medicinal honeys. Among study inpatients, n = 44,725 (93%) were treated with CCO, and n = 3,542 (7%) with medicinal honeys. CCO and medicinal honeys accounted for 1,826 (70%) and 773 (30%), respectively, of study outpatients. In adjusted models, those treated with CCO had lower odds for inpatient readmissions (OR = 0.86, 95% CI = 0.80-0.94) after inpatient index visits, and outpatient re-encounters both after inpatient (OR = 0.73, 95% CI = 0.67-0.79) and outpatient (OR = 0.78, 95% CI = 0.64-0.95) index visits in 6 months of follow-up.

LIMITATIONS

The study was observational in nature, and did not adjust for reasons why patients were hospitalized initially, or why they returned to the facility. Although the study adjusted for differences in a variety of demographic, clinical, and hospital characteristics between the treatments, we are not able to rule out selection bias.

CONCLUSION

Patients with CCO-treated PUs returned to inpatient and outpatient hospital settings less often compared with medicinal honey-treated PUs. These results from real-world administrative data help to gain a better understanding of the clinical characteristics of patients with PUs treated with these two debridement methods and the economic implications of debridement choice in the acute care setting.

Topical formulations of delta-aminolevulinic acid for the treatment of actinic keratosis: Characterization and efficacy evaluation

Actinic keratosis (AK) is a pre-cancerous disease, with worldwide increasing incidence, which consists in squamous cutaneous lesion caused by excessive exposure to ultraviolet radiation. An established treatment option is photodynamic therapy (PDT), based on light, oxygen and a photosensitizer. The most widely used is 5-aminolevulinic acid (ALA) which however, being a hydrophilic molecule, has difficultly penetrating the skin to achieve the desired therapeutic effect. To solve this limit, the present study provides for the development of three galenic gel formulations (Natrosol, Sepigel and Carbopol) containing 10% w/w of ALA for the treatment of AK with PDT and their comparison with a lipophilic cream used in the Hospital. The aim of this study is to offer an appealing topical treatment that improves patients' observance and compliance. Formulations were characterized in terms of chemical, physical and microbiological stability, viscosity and pH. An HPLC-DAD analytical method was also developed and validated. Sepigel gel resulted the best gel formulation in terms of technological characteristics and stability. A comparative study between this gel and the lipophilic cream was assessed, by evaluating the therapeutic efficacy and the compliance of the patients.

In vitro and ex vivo correlation of drug release from ophthalmic ointments

In vitro drug release testing and ex vivo transcorneal drug permeation can provide valuable information on the performance of the Q1/Q2 equivalent ointments prior to any animal studies. Good correlation between in vitro and ex vivo drug release may be indicative of good in vitro and in vivo correlation. Accordingly, it is important to investigate in vitro as well as ex vivo drug release from Q1/Q2 equivalent ophthalmic ointments and evaluate whether a correlation between these release profiles can be established. Four Q1/Q2 equivalent loteprednol etabonate ointments were prepared using different processing methods and excipient sources. The rheological parameters (crossover modulus and K value) of the four formulations were determined. The in vitro drug release testing of the four ointment formulations were performed using three different apparati (Franz diffusion cells, USP apparatus 2 with enhancer cells and USP apparatus 4 with semisolid adapters). Three models (zero order, logarithmic and the Higuchi model) were used to study the release kinetics of the ointment formulations. The transcorneal (rabbit corneas) permeation studies were performed using spherical joint Franz diffusion cells. The USP apparatus 4 method demonstrated better discriminatory ability compared to the USP apparatus 2 and the Franz diffusion cell methods. The in vitro release profiles of the four Q1/Q2 equivalent ointments with manufacturing differences showed a better fit using the Higuchi model (R² > 0.98) for all three release testing methods, compared to the other two models. Ex vivo drug release through the rabbit corneas displayed zero order release kinetics. A logarithmic correlation between rheological parameters (crossover and K value) and transcorneal flux were established. In addition, a plot of the in vitro release rate against the ex vivo release flux of the four ointment formulations, yielded a straight line (R² > 0.98) for all three release methods. Accordingly, the rheological parameters may be useful in predicting in vitro as well as ex vivo release properties.

OLEOGEL-S10 TO ACCELERATE HEALING OF DONOR SITES: MONOCENTRIC RESULTS OF PHASE III CLINICAL TRIAL

MATERIAL AND METHODS

Oleogel-S10, an ointment containing betulin-rich triterpene dry extract from birch bark was tested in an open, blindly evaluated, prospective, controlled, randomized multicentre study to improve wound healing in donor sites. The primary endpoint was time to wound closure, and secondary endpoints were scar related measurements at the time of wound closure, and 3 and 12 months after wound closure (POSAS, laser speckle contrast analysis, viscoelastic analysis).

RESULTS

We report the results from a single centre (Department of Burns and Reconstructive Surgery, University Hospital Brno) of this phase III clinical trial. A total of 32 patients (25 men and 7 women) were included with the mean patient age of 41.8 years (SD, ±11.66). The mean extent of patients donor sites in the study was 56.77cm2 (SD, ±20.39). Median healing time of the verum group (Oleogel-S10) was 7 days (95% Confidence Interval 7-8 days) and for controls 8 days (95% CI 7-10 days). Comparison of POSAS data from the verum group revealed significantly lower values at all three time points as compared to the controls. Perfusion of scars of the verum group reached on average of 115 perfusion units at the end of treatment; the average was 69.8 perfusion units at the 3-month follow-up and 50.2 perfusion units at the 12-month follow-up. Control sites displayed significantly higher values at all time points (122.2 perfusion units, 73.9 perfusion units, 52.2 perfusion units). Significant differences were detected in the skins viscoelastic properties, with sites treated with Oleogel-S10 displaying more favourable values.

CONCLUSION

In our results, we demonstrate the significant effectiveness of Oleogel-S10 in donor sites healingKeywords: Donor site, Triterpenes, Oleogel-S10, wound closure.

Arginine Silicate Inositol Complex Accelerates Cutaneous Wound Healing

Arginine silicate inositol (ASI) complex is a composition of arginine, silicon, and inositol that has been shown to have beneficial effects on vascular health. This study reports the effects of an ASI ointment on wound healing in rats. A full-thickness excision wound was created by using a disposable 5 mm diameter skin punch biopsy tool. In this placebo-controlled study, the treatment group's wound areas were covered by 4 or 10 % ASI ointments twice a day for 5, 10, or 15 days. The rats were sacrificed either 5, 10, or 15 days after the wounds were created, and biopsy samples were taken for biochemical and histopathological analysis. Granulation tissue appeared significantly faster in the ASI-treated groups than in the control groups (P < 0.05). The mean unhealed wound area was significantly smaller, and the mean percentage of total wound healing was significantly higher in ASI-treated wounds than in the control wounds. Hydroxyproline, collagen, and matrix metalloproteinases were measured in the granulated tissue and found to be affected. Inducible nitric oxide synthase (iNOS), endothelial nitric oxide synthase (eNOS), collagen, matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), vascular endothelial growth factor (VEGF), fibroblast growth factor (FGF), epidermal growth factor (EGF), nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB), and various cytokines (TNF-α and IL-1β) measured in this study showed a significant fall in expression level in ASI-treated wounds. The results suggest that topical application of ASI ointment (especially 4 % concentration) has beneficial effects on the healing response of an excisional wound.

Analysis on curative effects and safety of 2% liranaftate ointment in treating tinea pedis and tinea corporis & cruris

The paper is intended to analyze and evaluate the specific curative effect and safety of 2% liranaftate ointment in treating patients with tinea pedis and tinea cruris. 1,100 cases of patients with tinea pedis and tinea corporis & cruris were selected as research objects and were divided into two groups according to the random number table method. They were treated with different methods: 550 cases of patients were treated with 2% liranaftate ointment for external use in the observation group and the rest 550 cases of patients were treated with 1% bifonazole cream in the control group. The treatment time was two weeks for patients with tinea corporis & cruris and four weeks for those with tinea pedis respectively. Meanwhile, the one-month follow-up visit was conducted among the patients to compare the curative effects of two groups. After the medication, the curative effectiveness rate was 87.65% (482/550) in the observation group, while that was 84.91% (467/550) in the control group. After the average follow-up visits of (15.5±2.4), the curative effectiveness rate 96.55% (531/550) in the observation group, while that was 91.45% (503/550) in the control group. Two groups of patients recovered well with a low incidence of adverse reactions in the treatment, and the overall curative effect was good with the inter-group difference at P>0.05, so it was without statistical significance. The curative effect of 2% liranaftate ointment is safe and obvious in treating tinea pedis and tinea corporis & cruris, so it is valuable for clinical popularization and application.

Lignin-graft-Polyoxazoline Conjugated Triazole a Novel Anti-Infective Ointment to Control Persistent Inflammation

Lignin, one of the most abundant renewable feedstock, is used to develop a biocompatible hydrogel as anti-infective ointment. A hydrophilic polyoxazoline chain is grafted through ring opening polymerization, possess homogeneous spherical nanoparticles of 10-15 nm. The copolymer was covalently modified with triazole moiety to fortify the antimicrobial and antibiofilm activities. The hydrogel was capable of down regulating the expression level of IL-1β in LPS induced macrophage cells, and to cause significant reduction of iNOS production. It supported cellular anti-inflammatory activity which was confirmed with luciferase assay, western blot, and NF-κB analysis. This novel lignin-based hydrogel tested in-vivo has shown the abilities to prevent infection of burn wound, aid healing, and an anti-inflammatory dressing material. The hydrogel reported here provides a new material platform to introduce a cost-effective and efficient ointment option after undertaking further work to look at its use in the area of clinical practice.

Cost effectiveness of adding clostridial collagenase ointment to selective debridement in individuals with stage IV pressure ulcers

OBJECTIVE

The purpose of this study was to determine the cost effectiveness (from a payer's perspective) of adding clostridial collagenase ointment (CCO) to selective debridement compared with selective debridement alone (non-CCO) in the treatment of stage IV pressure ulcers among patients identified from the US Wound Registry.

METHODS

A 3-state Markov model was developed to determine costs and outcomes between the CCO and non-CCO groups over a 2-year time horizon. Outcome data were derived from a retrospective clinical study and included the proportion of pressure ulcers that were closed (epithelialized) over 2 years and the time to wound closure. Transition probabilities for the Markov states were estimated from the clinical study. In the Markov model, the clinical outcome is presented as ulcer-free weeks, which represents the time the wound is in the epithelialized state. Costs for each 4-week cycle were based on frequencies of clinic visits, debridement, and CCO application rates from the clinical study. The final model outputs were cumulative costs (in US dollars), clinical outcome (ulcer-free weeks), and incremental cost-effectiveness ratio (ICER) at 2 years.

RESULTS

Compared with the non-CCO group, the CCO group incurred lower costs ($11,151 vs $17,596) and greater benefits (33.9 vs 16.8 ulcer-free weeks), resulting in an economically dominant ICER of -$375 per ulcer. Thus, for each additional ulcer-free week that can be gained, there is a concurrent cost savings of $375 if CCO treatment is selected. Over a 2-year period, an additional 17.2 ulcer-free weeks can be gained with concurrent cost savings of $6,445 for each patient.

CONCLUSIONS

In this Markov model based on real-world data from the US Wound Registry, the addition of CCO to selective debridement in the treatment of pressure ulcers was economically dominant over selective debridement alone, resulting in greater benefit to the patient at lower cost.

Adverse effects of EMLA (lidocaine/prilocaine) cream and efficacy for the placement of jugular catheters in hospitalized cats

EMLA is a lidocaine/prilocaine cream used for topical analgesia in human pediatric patients. The purpose of this study was to establish the safety of EMLA in clinically ill cats, to measure systemic absorption and to determine whether EMLA reduced the need for sedation for the placement of jugular catheters. Thirty-one cats were randomized to either a placebo or EMLA cream group. Cream was applied to a 10 cm2 area over the jugular vein, with 1 h of occlusive dressing. Neither anesthetic was systemically absorbed in any cat, and no adverse clinical signs were observed. Struggling during catheter placement was less in the EMLA-treated cats compared to placebo, but did not reach significance ( P=0.06). Jugular catheters were successfully placed in 60% of EMLA-treated cats and 38% of placebo cats; this difference was not statistically significant and may not justify the added steps of EMLA cream administration for this purpose. However, EMLA does appear to be safe in clinically ill cats, and may be useful for other applications such as for skin mass removal or repeated venepuncture.

Topical Minocycline Foam for the Treatment of Impetigo in Children: Results of a Randomized, Double-Blind, Phase 2 Study

BACKGROUND

Currently available treatment options for impetigo are limited by either systemic side effects (for oral therapy) or lack of ease of use (for topical ointment). A novel foam formulation of minocycline for topical use may improve convenience and treatment utilization for pediatric patients with impetigo.

OBJECTIVE

To evaluate the safety and efficacy of topically applied minocycline foam (FMX-102 1% and 4%) in the treatment of impetigo and to determine the optimal therapeutic active ingredient concentration.

METHODS

In this randomized, parallel-group, double-blind, comparative clinical trial, 32 subjects aged ≥2 years with a clinical diagnosis of pure impetigo, impetigo contagiosa, or uncomplicated blistering impetigo were randomized to treatment with FMX-102 1% or 4%, twice daily for 7 days. Subjects were followed for up to 7 days post-treatment.

RESULTS

Clinical cure, defined as ≥80% cured lesions (fully recovered lesions, visually determined by investigators), was achieved by 57.1% and 50.0% of FMX-102 1% and 4% subjects, respectively, at the end of treatment (visit 3). Clinical success, defined as the absence of lesions, or the drying or improvement of treated lesions (decrease in size of affected area, lesion number, or both), was demonstrated in 81.3% and 78.6% of FMX-102 1% and 4% subjects, respectively, following 3 days of treatment (visit 2), in 92.3% and 100% of the respective subjects at the end of treatment, and in 100% in both groups at follow-up (visit 4). Bacteriologic success rates at the end of treatment, defined as complete pathogen eradication, were 85% and 74% in the FMX-102 1% and 4% groups, respectively. The bacteriologic success rate for MRSA infections was 100% (11/11), with no recurrences. Both FMX-102 1% and 4% were considered well tolerated and safe.

CONCLUSION

Topical minocycline foam may be a safe and effective new treatment option for impetigo in children, including those with MRSA. <br /><br /> <em>J Drugs Dermatol.</em> 2016;15(10):1238-1243.

A multi-centred open trial of “Dr Michaels®” (also branded as Soratinex®) topical product family in psoriasis

Psoriasis is a chronic, recurring skin disease affecting 2-4% of the population. Genetic predisposition and precipitating factors play a role in its etiology. The disease can occur in any age or gender group. The most frequently affected areas of the body include scalp, extensor surfaces of the extremities, skin folds and nails. While a number of therapies exist for the treatment of psoriasis with a total resolution of the skin, achieving remission in a high percentage of sufferers, a treatment that results in the maintenance of remission and is free of side effects is still a desirable goal. The aim of the study was to investigate the efficacy and tolerability of Dr Michaels® (Soratinex®) topical product family in psoriasis, in terms of decreasing parakeratosis, inflammation, infiltration and involved area. Seven-hundred-and-twenty-two subjects, mean age 42.3 years (range: 18-68 years) with mild to moderately severe psoriasis, with no other current anti-psoriatic therapy, consisting of 382 males and 340 females, above 18 years of age were included and the observations were subjected to statistical analysis. Triphasic application of Dr Michaels® (Soratinex®) products was employed for 8 weeks, using Cleansing Gel, Scalp and Body Ointment and Skin Conditioner. The treatment proved to be ineffective for 22 patients (3.1%) out of 722. 84 patients (11.6%) had moderate improvement with 26-50% of cleared skin lesions; 102 patients (14.1%) had good improvement with 51-75% of cleared skin lesions; 484 patients (67.0%) experienced outstanding improvement with 76-100% of the cleared skin lesions, with 52% of them achieving total resolution. Twelve patients worsened and discontinued treatment; 18 patients discontinued because of non-compliance; 33 patients developed folliculitis as a side effect. Based on the results of this study, the Dr Michaels® (Soratinex®) product family can be successfully applied in mild to moderately severe psoriasis when considering the exclusion criteria.

Efficacy and safety of Dr Michaels® (Soratinex®) product family for the topical treatment of psoriasis: a monitored status study

The aim of the study was to investigate the efficacy and safety of Michaels® (Soratinex®) remedies in patients suffering from chronic plaque psoriasis in a Czech population. Seventy-five (34 female/41 male) patients, aged 18-72 years old (mean age: 38.5 years) with mild to severe plaque psoriasis participated in the study. The products, including cleansing gel, ointment and skin conditioner, containing fruit acid complex, herbal oils and emulsifiers, were used twice daily and in the same manner for all the skin lesions. The study period was eight weeks. Histologic variables and various blood picture parameters, including FW, glucose, cholesterol, triacylglyceroles, bilirubin, GMT, ALT, AST, creatinine, uric acid and urea in blood were monitored, before and after therapy with Michaels® (Soratinex®) treatment. Assessment, using the Psoriasis Activity Severity Index (PASI) scores and photographic analysis, was done at time 0, and after 2, 4, 6 and 8 weeks. Patient’s improvement was determined by the percentage reduction of the PASI scores. Side effects and tolerability were also evaluated. After 8 weeks using Dr Michaels® (Soratinex®) treatment course, 5 patients had a moderate improvement, with the resolution of 25-50% of skin lesions; 11 patients showed a good improvement, with the resolution of 51-75% of lesions. Another 50 patients had an outstanding improvement, with the regression of 76-100% of lesions. Only 4 patients did not achieve an improvement of psoriasis. Six patients experienced folliculitis, which resolved without cessation of treatment. Three patients worsened and discontinued treatment. Six patients dropped out because of non-compliance. The blood results and histologic findings were all normal. Our investigation shows that Dr Michaels® (Soratinex®) products can be safely and successfully used in the treatment of chronic plaque psoriasis.

Clinical evaluation of the effectiveness of “Dr Michaels®” (also branded as Soratinex®) products in the topical treatment of patients with plaque psoriasis

Psoriasis is generally considered as an autoimmune inflammatory cutaneous-systemic disease, with chronic course and high rate of recurrence, while its high risk of comorbidities affect the patients’ quality of life significantly. Despite the good therapeutic response, most of the available options show tendency for poor tolerance and high rate of occurrence of side effects. Therefore, the interest of patients and doctors to investigate the possibility of treating psoriasis with natural substances is not surprising. The aim of this study was to investigate the efficacy and safety of the herbal skin-care product Dr Michaels® (Soratinex®) for the management of chronic plaque psoriasis, within a 6 to 8 week treatment course. Thirty patients of both sexes, aged between 24 and 70 years with mild to moderate psoriasis vulgaris were included in this study. The products of Dr Michaels® (Soratinex®) were applied in sequence: cleansing gel, ointment after 3-4 minutes and tonic care (for the fire-smeared ointment) 2 times per day for restorative care and cleansing gel for psoriasis within scalp 3 times a week. The study lasted six weeks. The severity and extent of the lesions were evaluated by PASI score (Psoriasis Area and Severity Index). Based on the obtained result, the products of “Dr Michaels® (Soratinex®)” have proved to be effective in the treatment of mild and moderate psoriasis vulgaris. In the study group, no improvement was observed in 10% of patients, a slight improvement in 20%, good in 40% and very good in 16.6% of patients.

Investigation of the efficacy and tolerability of Dr Michaels® (also branded as Eczitinex® and Itchinex Eczitinex®) topical products in the treatment of atopic dermatitis in children

Atopic eczema is a chronic relapsing inflammatory skin disorder, characterized clinically by intensely pruritic eczematous skin lesions and a defective epidermal barrier. It affects more than 15% of children and up to 10%of adults, which makes the disease a social health problem still without a challenging treatment. The aim of this study was to evaluate the efficacy and tolerability of Dr Michaels® (Eczitinex®) topical product family in the treatment of atopic dermatitis in children. We studied a group of 30 patients (17 female, 13 male), aged 5 to 13 (mean age: 9), affected by atopic dermatitis since they were newborn. All patients had been unsuccessfully treated with conventional anti-inflammatory therapies and ceased treatment 2 weeks before commencing research. The patients were treated with Dr Michaels® (Eczitinex® and Itchinex®) product family including a moisturising bar, topical ointment and PSC 900 oral herbal formulation. The treatment was evaluated clinically and photographically at 0, 1, 2, 4, 6, 8, 10, 12, and 14 weeks. Twenty-eight patients showed a significant improvement of cutaneous rashes and pruritus on the first week of treatment, with a complete remission at 10-12 weeks. Only two patients, brother and sister respectively, showed a slow response to treatment and reported an increasing itching. Following 14 weeks of treatment with the Dr Michaels® (Eczitinex® and Itchinex®) product family, patients demonstrated complete resolution of their AD. All patients showed a marked improvement in their condition within 3 days of treatment with most of the lesions and symptoms totally resolved within 10 to 12 weeks of treatment with Dr Michaels® (Eczitinex® and Itchinex®) family of products. This clinical report highlights that the Dr Michaels® (Eczitinex® and Itchinex®) product family is a safe and effective treatment option for AD.

Treatment of ichthyosis lamellaris using a series of herbal skin care products family

Lamellar ichthyosis (LI) is a genetically heterogeneous group of disorders of keratinization that are inherited in an autosomal recessive fashion, occurring in approximately 1 in 300,000 live births. The treatment of the large, dark, plate-like scales that characterize the classic manifestation of the disease are still a challenge. The aim of this study was to evaluate the efficacy and tolerability of Dr. Michaels® skin-care products for the management of LI. A multi-centre European prospective study was conducted, including 10 patients (3 female/7 male) with lamellar ichthyosis, aged 38-54 years old (mean age: 46). Each patient had been treated with emollients plus other different systemic therapies, such as corticosteroids, Cyclosporin A or retinoids in the past. All patients were treated with Dr Michaels® product family including both topical and oral herbal supplements. The topical treatments used were the cleansing gel, activator formula and ointment. The oral medications were PSC 200, PSC 400 and PSC 900. Within 3 weeks of initiation of treatment, there were improvements observed on the skin including a reduction in scaling, fissuring, and intensity in erythema and pruritus with thinning of the hyperkeratotic plate. After 12-15 weeks, most of the plates and scales had been removed to reveal a normalised skin colour. Evidence of hair, eyelash and eyebrow growth was observed. There was partial nail resolution with a reduction in subungual hyperkeratosis. No adverse reactions were observed. Our patients showed excellent symptomatic response to treatment within a 14-week period, follow-up by an on-going regular assessment on a quarterly basis. The results show that Dr Michaels® product family is an effective and safe treatment option for LI.

[Local Control of Advanced Breast Cancer with Mohs Paste and Systemic Therapy]

Unresectable locally advanced breast cancer results in a decline in patient quality of life because of the presence of bleeding, exudates, and strong odor. The clinical application of supportive care using Mohs paste for improving quality of life has become widespread. We report 2 cases of locally advanced breast cancer treated with systemic therapy and chemosurgery. Case 1 was a Japanese woman in her fifties who had a locally advanced left breast cancer. She had continuous bleeding and exudates, and received Mohs chemosurgery and endocrine therapy. One month later, the surface healed and dried up. The bleeding, exudates, and strong odor disappeared almost completely. Case 2 was a Japanese woman in her forties who had a locally advanced left breast cancer with massive exudates and oozing blood. She underwent Mohs chemosurgery 20 times, but the exudates and bleeding were not controlled. According to pathological findings, we confirmed her breast cancer to be of the triple negative subtype. After 2 courses of therapy with 5-fluorouracil, epirubicin, and cyclophosphamide, the tumor immediately decreased in diameter by 65%. The bleeding, exudates, and strong odor disappeared. Although Mohs chemosurgery is useful for local control of locally advanced breast cancer, this alone is insufficient to treat the disease. Early introduction of systemic therapy is considered essential in breast cancer treatment.

Successful treatment of a chronic eczema in a 48-year-old female with Dr Michaels® (Eczitinex® and Itchinex®) product family. A case report

We report the case of a 48-year-old female with chronic atopic eczema who responded successfully to Dr Michaels® (Eczitinex® and Itchinex®) product family. The patient had a 41-year history of atopic eczema and presented with erythematous, excoriated lesions with telangiectasia and scattered purpura (bruising) covering 90% of her body surface area. The patient also regularly suffered blepharitis with red, itchy, watery eyes. The patient was treated with Dr Michaels® (Eczitinex® and Itchinex®) ointment and herbal supplements and presented total resolution of the atopic eczema and underlying inflammation within 6 weeks. This case also suggests that Dr Michaels® (Eczitinex® and Itchinex®) product family is safe and effective, even in cortisone acquired sensitive skin.

Successful treatment of recalcitrant candidal intertrigo with Dr Michaels® (Fungatinex®) product family

Candidal intertrigo is an infection of the skin caused by Candida albicans that typically occurs in opposing cutaneous or muco-cutaneous surfaces. Because Candidiasis requires a damaged and moist environment for infection, it typically occurs in areas of friction such as the skin folds of the body. Candidal intertrigo is often difficult to treat and results are often unsatisfactory. In addition, there is a lack of evidence-based literature supporting prevention and treatments for candidal intertrigo. The aim of the study was to evaluate the efficacy of Dr Michaels® (also branded as Fungatinex®) products in the treatment of fungal intertrigo, in 20 women and 2 men with a mean age of 72. Five patients (3 female and 2 male) had type 2 diabetes and 16 (14 female and 2 male) were obese. The patients were treated with Dr Michaels® (Fungatinex®) moisturising bar, topical ointment (twice daily application) and oral herbal formulation, PSC 200 two tablets twice daily with food. After 2 weeks of treatment, the lesions had mostly resolved in all patients with only slight erythema evident. After six weeks of treatment using the moisturising bar, topical ointment and oral herbal formulations from the Dr Michaels® (Fungatinex®) product family, the lesions had totally resolved in 18 patients, while 4 patients had to continue the therapeutic protocol for another 2 weeks. Our results demonstrate that the Dr Michaels® (Fungatinex®) complementary product family is efficacious in the treatment of recalcitrant candidal intertrigo. Furthermore, this study highlights that the Dr Michaels® (Fungatinex®) product family is fast-acting and well tolerated with no serious adverse events reported. These data have important implications for resistant cases of candidal intertrigo where traditional therapies have failed.

Liquid Crystal Formulation and Optimization of Anti-Microbial Polyherbal Ointment

We examined the formulation of liquid crystalline systems (LCS) including 5% TSE extracts and analyzed marker substances of the 5% TSE ointment by HPLC-DAD. The TSE extracts were evaluated for its anti-bacterial activity against Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, and Candida albicans. We found the extracts showed predominant activity against selected bacterial species. The result of the polarized light microscopy, differential scanning calorimetry (DSC), small-angle X-ray diffraction (SXRD), and rheology analysis indicated the presence of LCS structures with lamellar arrangement. DSC of the TSE formulas showed higher transition peak temperature at 60 °c for the phase. SXRD observation of the LCS formulas showed that the structures of the LCS formulas were in the lamellar liquid crystalline phase. Further, to ensure the quality and purity of the TSE ointment, HPLC analysis was performed by measuring the. content of 2 marker substances. The contents of marker substances in the TSE ointment were calculated as 0.078% (paeoniflorin) and 0.031% (glycyrrhizin), respectively. Taken altogether, our study report successful generation of LCS made of 5% TSE ointment and its antimicrobial activity. Moreover, the quantitation of the two active components enable a proper quality control of the TSE extracts, that is essential for the development of ointment products.

Antimicrobial Activity and pH of Calcium Hydroxide and Zinc Oxide Nanoparticles Intracanal Medication and Association with Chlorhexidine

AIM

To evaluate pH and antibacterial activity of pastes with calcium hydroxide [Ca(OH)2] and zinc oxide (ZnO) microparticles (micro) or nanoparticles (nano) and association with 0.4% chlorhexidine against Enterococcus faecalis.

MATERIALS AND METHODS

The following pastes were analyzed: Ca(OH)2/ZnO micro, (2) Ca(OH)2/ZnO nano, (3) Ca(OH)2/ ZnO micro + 0.4% chlorhexidine, (4) Ca(OH)2/ZnO nano + 0.4% chlorhexidine. Antibacterial activity against E. faecalis was evaluated by agar diffusion test. The direct contact test on planktonic cells of E. faecalis was performed for 30 and 60 seconds. Root canals from bovine teeth were filled with the pastes and pH was evaluated after 1, 7, 14, 21, 30 and 60 days. The data obtained were submitted to the statistical tests analysis of variance (ANOVA) and Tukey or Kruskal-Wallis and Dunn test, with a 5% significance level.

RESULTS

Calcium hydroxide and zinc oxide nano, and the pastes with 0.4% chlorhexidine were more effective in agar diffusion test. In the direct contact test, the pastes with chlorhexidine showed the highest effect after 30 seconds. All pastes eliminated E. faecalis after 60 seconds. All pastes promoted an increase in pH. The highest increase in pH was observed with nanoparticle medications after 1 and 7 days (p < 0.05). After this period, the pastes presented similar pH increase.

CONCLUSION

It was concluded that calcium hydroxide and zinc oxide nanoparticles promoted greater initial alkalinization. The antimicrobial activity of the pastes against E. faecalis is favored by the association with chlorhexidine.

CLINICAL SIGNIFICANCE

Although nanoparticles of calcium hydroxide and zinc oxide promoted antibacterial effect, the activity against E. faecalis is favored by association with chlorhexidine.

Comparing the Effect of a Twice-weekly Tacrolimus and Betamethasone Valerate Dose on the Subclinical Epidermal Barrier Defect in Atopic Dermatitis

The proactive use of topical anti-inflammatory (TAI) therapy to address subclinical inflammation is an effective, contemporary clinical strategy for the management of atopic dermatitis (AD). The interaction of a proactive TAI dose with the subclinical epidermal barrier defect in AD is yet to be determined. A randomised, observer-blind, functional mechanistic study in 17 subjects with quiescent AD was performed to compare the effect of a twice-weekly dose of betamethasone valerate (0.1%) cream (BMVc), against tacrolimus (0.1%) ointment (TACo) on the biophysical and biological properties of the epidermal barrier. Application of BMVc preserved epidermal barrier function and stratum corneum (SC) integrity, but significantly elevated skin-surface pH with concomitant loss of SC cohesion. By contrast, TACo improved SC integrity, exerted an overall hydrating action, and significantly reduced caseinolytic and trypsin-like protease activity. The differential effects reported support the proactive use of TACo to promote reparation of the subclinical barrier defect in AD.

The Efficacy of 1% Chloramphenicol Eye Ointment Versus 2.5% Povidone-Iodine Ophthalmic Solution in Reducing Bacterial Colony in Newborn Conjunctivae

PURPOSE

This study aimed to evaluate bacterial pattern and reduction of bacterial colonies in neonatal conjunctivae after prophylaxis 1% chloramphenicol eye ointment and 2.5% povidone-iodine ophthalmic solution.

DESIGN

A double-blind randomized controlled trial was conducted.

METHODS

Swabs were taken from the inferior fornix conjunctiva of the right eyes of 60 newborns 1 hour after birth. Either the 2.5% povidone-iodine ophthalmic solution or the 1% chloramphenicol eye ointment was randomly applied to the conjunctivae. Conjunctival swabs were taken 2 hours after prophylaxis treatment. Specimens were delivered to the Microbiology Laboratory to determine the number of bacterial colonies and to evaluate bacterial pattern.

RESULTS

Sixty eye specimens were included in the study. Bacterial growth was shown in 44 eye specimens, whereas it was not found in the remaining 16 eye specimens. The bacteria found in neonatal conjunctivae was gram-positive coccus (61%), followed by gram-positive bacillus (36%) and gram-negative bacillus (2%). Both agents significantly reduced the bacterial colony-forming unit (P = 0.00); however, the effect was not significantly different as shown by statistics between both groups (P = 0.748), indicating that the 2.5% povidone-iodine ophthalmic solution had a similar effect to the 1% chloramphenicol eye ointment. No adverse effect such as toxic conjunctivitis or corneal haziness was found in both groups.

CONCLUSIONS

The 2.5% povidone-iodine ophthalmic solution has been proven as effective as the 1% chloramphenicol eye ointment and induces no toxic reaction. Because it is less expensive than the other, it could be recommended as a good alternative for ophthalmia neonatorum prophylaxis. Further studies with a larger sample size should be conducted to confirm its cost-effectiveness.

[Trichophyton rubrum onychomycosis with secondary Aspergillus versicolor infection in a 12-year-old girl: successful topical therapy with terbinafine-urea ointment]

CASE REPORT

A 12-year-old with a functional circulatory disturbance had toe nail onychomycosis caused by Trichophyton rubrum. There were no other underlying diseases.

THERAPY AND OUTCOME

Oral therapy with terbinafine 125 mg once weekly in addition to ciclopirox nail lacquer was ineffective. Two years later the disease worsened and A. versicolor was found in pure culture. A preparation of 10% terbinafine HCl in a 20% urea ointment (Onychomal®) applied daily for 4 weeks, then once weekly resulted in complete cure after 7 months.
