Comparative analysis of surgical and non-surgical wound approaches in diabetic foot ulcer treatment: Meta-analysis and systematic review

The assessment for safety and effectiveness of surgical interventions in the management of diabetic foot ulcers (DFUs) in comparison to non-surgical approaches was performed. A comprehensive search was performed across PubMed, MEDLINE, Cochrane Library and EMBASE in order to identify case-control studies, randomized controlled trials (RCTs), observational studies, cohort studies and observational studies pertaining to DFU treatments. Studies conducted in English language and focusing on wound healing rates, recurrence rates, time to healing and complication management met the inclusion criteria. There were six studies included in this meta-analysis. Surgical procedures, such as debridement, revascularization and skin transplantation, demonstrated significantly superior efficacy in promoting wound healing (84%) and shorter duration of healing (6 weeks) in comparison to non-surgical approaches, including off-loading, wound dressings and pharmacological therapies. Surgical interventions for DFUs resulted in a wound recovery rate of 84%, a significantly higher mean rate than non-surgical approaches (60%) that was observed. In addition, it was observed that the surgical group experienced considerably reduced average healing period of 9 weeks, in contrast to the non-surgical group's mean healing period of 12 weeks. Nevertheless, it is imperative to acknowledge that surgical procedures were notably correlated with a heightened occurrence of complications, such as amputations, which transpired in 19% of instances. Surgical interventions for DFUs may provide superior short-term results with regard to healing rates and recovery time, as indicated by this meta-analysis. However, they are additionally correlated with the heightened likelihood of complications. Although non-surgical techniques offered comparatively secure option, they were also less reliable. Individualized treatment modalities should be chosen in consideration of patient-specific factors and comparative advantages and disadvantages.

The Influence of Honey and Hydrogel Products Therapy on Healing Time in Diabetic Foot

BACKGROUND

Diabetic foot ulcer is a serious and common complication of diabetes that often leads to significant morbidity and even amputation if not properly treated. Current treatment options, such as wound dressing, have limitations in promoting efficient healing. There is a need for effective interventions that can expedite the healing process and enhance the time required for complete healing.

METHODOLOGY

This prospective single-blinded randomized control trial studied diabetic mellitus type 2 patients with ulcer in their second-degree feet from February 2019 to February 2023 in the Diabetic Foot Center, King Fahad Specialist Hospital Al Qassim-KSA.

RESULTS

This study involved 120 patients with a mean age of 59.64 ± 10.21. And 63% to 52.5% of them were males and 57% to 47.5% were females. The mean healing time was about 12.76 ± 4.08 days. Cases were divided into 4 equal groups with altered treatment procedures: honey alone, hydrogel alone, honey, and hydrogel combination alternately (3 intervention groups), and fucidin ointment or cream alone (1 control group), with 30 participants in each group. We revealed that the mean healing times for honey alone, hydrogel alone, and honey and hydrogel alternately were 12.20, 13.97, and 10.83 days, respectively. While it was 14.03 days in the control Fucidin ointment or cream [significantly P < .05 (P = .004)].

CONCLUSION

From the findings of the present study, we noticed that faster healing time among diabetic foot cases could be accomplished by treatment with a combination of honey and hydrogel alternately. Therefore, this therapy is effective in reducing the risk of diabetic foot ulcers.

The Impact of Topical Application of Platelet-Rich Fibrin on Graft Survival in Surgeries for Chronic Otitis Media

OBJECTIVE

This study aims to evaluate the efficacy of platelet-rich fibrin (PRF) application in tympanoplasty procedures for patients with chronic otitis media (COM), assessing its influence on graft survival and healing time.

METHODS

In this prospective interventional study, conducted between January 2022 and June 2023, 80 patients diagnosed with COM were enrolled and divided into two groups. Group A underwent standard tympanic membrane repair using temporal fascia grafts (TFG), while Group B received TFG with adjunctive PRF application. The patients were observed and assessed over a 20-week postoperative period.

RESULTS

The study showed a significant enhancement in graft survival rates in Group B (TFG+PRF), with only one residual perforation compared to seven in Group A (TFG alone) at 20 weeks (p=0.02534). Furthermore, Group B patients experienced faster healing, achieving 97.5% graft integrity at 10 and 20 weeks, in contrast to Group A's 87.5%.

CONCLUSION

The application of PRF in tympanoplasty procedures for COM notably enhances graft stability and expedites the healing process. These findings suggest that PRF can be a valuable adjunct in otolaryngological surgeries, offering potential improvements in patient outcomes and surgical efficacy.

Collagen Application in Pediatric Superficial Burns: The Right Time!

Introduction  Delayed presentation of burn patients, in a developing country with the patient being referred from one center to another higher one, is a common occurrence. Efficient management of such delayed burn wounds thus becomes critical to decrease the morbidity of the patient within economic constraints. The advantages of collagen dressing are numerous. However, there is scarce literature on the timing of its application. Traditionally, it is thought that collagen sheets should be applied within 24 hours of burns as the wound is still sterile. This thus becomes ironical as patients are presenting late. Hence, we studied retrospectively the result of collagen application in delayed presentation of burns. Methods  A retrospective study was conducted in which records of pediatric patients of less than 10 years with less than 30% total body surface area scald burns were considered. Collagen dressing was done in all these patients. Presentation time from burns, timing of collagen application, status of wound at various check dresses, complication of burn wound, and total healing times were recorded. Appropriate statistical formulas were used to calculate significance levels for continuous and categorical variables. Result  Fifty-three patients, 33 male and 20 female were studied. The most common cause of scald was hot water spillage from baths and cooking, with the anterior trunk being the most involved site. The mean time of presentation of the patient from burns is 71.74 hours and that of collagen application was 76.4 hours. Fourteen (25.4%) patients had wound complications in the form of soakage, fever, and pus. Eight patients had their collagen removed. The average healing time for patients with intact collagen was 12.15 days and that for those on daily dressing was 21.9 days. Conclusion  Collagen should be preferred even when the patient presents after 24 hours of burns. A thoroughly washed wound is a necessary prerequisite before collagen application. Burn patients presenting after 3 days have a higher incidence of wound infection. No such time stamp of application of collagen sheets within 24 hours can thus be given for its use as the advantages of adhered and successful collagen dressings outweigh those on daily dressings.

The usefulness of platelet-rich plasma to manage skin wounds: A meta-analysis

A meta-analysis investigation to measure the usefulness of platelet-rich plasma (PRP) to manage skin wounds (SWs). A comprehensive literature inspection till February 2023 was applied and 1349 interrelated investigations were reviewed. The 22 chosen investigations enclosed animals' SWs were in the chosen investigations' starting point, 3348 of them were treated with PRP, and 2259 were control. Odds ratio (OR) in addition to 95% confidence intervals (CIs) were used to compute the value of the usefulness of PRP to manage SWs by the dichotomous and continuous approaches and a fixed or random model. PRP significantly higher percent of decreases in open wound area (OWA) (MD, 10.07; 95% CI, 6.55-13.59, P < 0.001), and lower healing time (HT) (MD, -6.31; 95% CI, -10.69 to -1.93, P = 0.005) compared to control in animals' SWs. PRP had a significantly higher percent of decreases in OWA and lower HT compared to control in animals' SWs. However, caused of the small sample sizes of several chosen investigations for this meta-analysis, care must be exercised when dealing with its values.

Efficiency of platelet-rich plasma in the management of burn wounds: A meta-analysis

The meta-analysis aimed to assess the efficiency of platelet-rich plasma (PRP) in the management of burn wounds (BWs). Using dichotomous or contentious random- or fixed-effects models, the outcomes of this meta-analysis were examined and the odds ratio (OR) and the mean difference (MD) with 95% confidence intervals (CIs) were computed. Thirteen examinations from 2009 to 2023 were enrolled for the present meta-analysis, including 808 individuals with BWs. PRP had significantly shorter healing time (MD, -5.80; 95% CI, -7.73 to -3.88, p < 0.001), higher healing rate (OR, 3.14; 95% CI, 2.05-4.80, p < 0.001), higher healed area percent (MD, 12.67; 95% CI, 9.79-15.55, p < 0.001) and higher graft take area percent (MD, 4.39; 95% CI, 1.51-7.26, p = 0.003) compared with standard therapy in patients with BW. However, no significant difference was found between PRP and standard therapy in graft take ratio (OR, 1.70; 95% CI, 0.86-3.34, p = 0.13) and infection rate (OR, 0.55; 95% CI, 0.20-1.47, p = 0.23) in patients with BW. The examined data revealed that PRP had a significantly shorter healing time, a higher healing rate, a higher healed area percent and a higher graft take area percent; however, no significant difference was found in graft take ratio or infection rate compared with standard therapy in patients with BW. Yet, attention should be paid to its values since all of the selected examinations had a low sample size and some comparisons had a low number of selected studies.

Resistant distal femoral nonunion treated with combined nail/plate construct and reamer-irrigator-aspirator technique

OBJECTIVE

This study was performed to evaluate the effectiveness of intramedullary nailing and a lateral locking plate combined with the reamer-irrigator-aspirator (RIA) bone grafting technique for resistant distal femoral nonunion.

METHODS

This retrospective observational study was performed from January 2018 to December 2021 and involved five patients who presented with resistant distal femoral nonunion despite undergoing several surgeries. They were treated with intramedullary nailing and a lateral locking plate combined with the RIA bone grafting technique. Postoperative follow-up was performed to observe the healing time, and functional outcomes were evaluated using the Lower Extremity Functional Scale (LEFS).

RESULTS

After the patients had been monitored for a mean of 17.9 months, complete bone healing was observed in every patient (mean healing time of 4.8 months). Postoperative wound failure in an older patient was successfully treated with resuturing and nutritional assistance. At the last follow-up, the mean LEFS score was 71.2/80 and the mean knee flexion was 109 degrees.

CONCLUSIONS

Our study demonstrates that combining intramedullary nailing and a lateral locking plate with the RIA bone grafting technique enhances biological properties, provides good structural support, and achieves good union and functional results in the management of resistant nonunion of the distal femur.

Variables That Could Influence Healing Time in Patients with Diabetic Foot Osteomyelitis

AIM

To compare the healing time in patients with diabetic foot osteomyelitis according to the presence or absence of clinical signs of infection, variation of blood parameters, the presence of different radiological signs, and the treatment received for the management of osteomyelitis.

METHODS

A prospective observational study was carried out in a specialised Diabetic Foot Unit between November 2014 and November 2018. A total of 116 patients with osteomyelitis were included in the study (treated by either a surgical or medical approach). During the baseline visit, we assessed the diagnosis of osteomyelitis, demographic characteristics and medical history, vascular and neurological examination, clinical signs of infection, increased blood parameters, radiological signs of osteomyelitis, and the treatment to manage osteomyelitis. We analysed the association between the presence of clinical signs of infection, variation of blood parameters, presence of radiological signs, and treatment received for management of osteomyelitis with the healing time.

RESULTS

The mean time to ulcer healing was 15.8 ± 9.7 weeks. Concerning healing times, we did not find an association with the presence of clinical signs of infection or with the increase in blood parameters, except in the case of eosinophils, which with higher values appear to increase the healing time (U = 66, z = -2.880, p = 0.004). Likewise, no relationship has been found between healing time and the appearance of the different radiological signs of osteomyelitis, nor depending on the treatment administered for the management of osteomyelitis.

CONCLUSION

High levels of eosinophils are associated with a longer healing time of diabetic foot ulcers complicated with osteomyelitis, finding no other factors related to increased healing time.

Healing Time of Skin Ulcers in Homecare Residents in the Province of Reggio Emilia, Northern Italy

The growing phenomenon of skin ulcers represents an important health problem; therefore, we conducted a pilot study to evaluate the ulcer healing time among adult subjects followed by the Home Nursing Service of the AUSL-IRCCS of Reggio Emilia, Northern Italy, and diagnosed with at least one skin ulcer during the period of January-August 2020. We recruited 138 subjects (45.5% men) with a mean age of 86.1 years. The subjects presented with 232 ulcers, of which 76.7% were pressure ulcers (60.1% were stage II), 18.1% were vascular ulcers, and 4.7% were diabetic foot ulcers. Ulcer management required only one weekly access for the majority of subjects, with a recovery frequency of 53.6% at the end of the observation period. The median ulcer healing time was 3.6 months and was shorter in women (2.6 months) than men (5.1 months), with an increasing trend according to the number of ulcers and the severity of pressure ulcers for vascular and diabetic foot ulcers. In conclusion, this is the first study carried out in an Italian population describing the distribution and characteristics of homecare residents with skin ulcers and highlighting the factors influencing the healing time and as consequence the duration of nursing care.

Photoacoustic monitoring of angiogenesis predicts response to therapy in healing wounds

Chronic wounds are a major health problem that cause the medical infrastructure billions of dollars every year. Chronic wounds are often difficult to heal and cause significant discomfort. Although wound specialists have numerous therapeutic modalities at their disposal, tools that could three dimensional-map wound bed physiology and guide therapy do not exist. Visual cues are the current standard but are limited to surface assessment; clinicians rely on experience to predict response to therapy. Photoacoustic (PA) ultrasound (US) is a non-invasive, hybrid imaging modality that can solve these major limitations. PA relies on the contrast generated by haemoglobin in blood which allows it to map local angiogenesis, tissue perfusion and oxygen saturation-all critical parameters for wound healing. This work evaluates the use of PA-US to monitor angiogenesis and stratify patients responding versus not-responding to therapy. We imaged 19 patients with 22 wounds once a week for at least 3 weeks. Our findings suggest that PA imaging directly visualises angiogenesis. Patients responding to therapy showed clear signs of angiogenesis and an increased rate of PA increase (p = 0.002). These responders had a significant and negative correlation between PA intensity and wound size. Hypertension was correlated to impaired angiogenesis in non-responsive patients. The rate of PA increase and hence the rate of angiogenesis was able to predict healing times within 30 days from the start of monitoring (power = 88%, alpha = 0.05). This early response detection system could help inform management and treatment strategies while improving outcomes and reducing costs.

Effectiveness and safety of oral acyclovir 1 g twice a day for 3 days in the management of genital herpes

Context:

Acyclovir is the most commonly used drug in genital herpes; however, with existing acyclovir regimens, the drug needs to be taken five times a day which is inconvenient for patients.

Aims:

The aim of the study was to evaluate the efficacy and safety of oral acyclovir 1 g twice a day for 3 days in genital herpes.

Methods:

The patients of genital herpes were treated with oral acyclovir 1 g twice a day for 3 days and followed up after day 3, 5, 7, and 10 to determine the response to therapy. The response was assessed by physicians' assessment of percentage healing of the ulcer and mean healing time as well as patients' assessment of improvement in the Visual Analog Scale (VAS).

Results:

Twenty-three patients of genital herpes were recruited of which 21 (91.3%) had recurrent episodes, whereas 2 (8.7%) patients had first episode. One patient was lost to follow-up and 22 were analyzed. Complete healing of ulcer was seen in 9 (40.9%), 17 (77.27%) and 20 (90.90%) patients after day 3, 5 and 7 following the treatment respectively, with a mean healing time of 4.91 ± 2.16 days. The mean healing time of recurrent disease was 4.67 ± 1.87 days. Complete improvement in VAS was seen in 9 (40.9%), 21 (95.45%) and 22 (100%) patients after day 3, 5 and 7 following the treatment respectively, with a mean time for complete improvement being 4.27 ± 1.16 days. There were no significant side effects of therapy.

Conclusion:

Acyclovir 1 g twice a day for 3 days is an effective treatment for genital herpes with advantages of comparable healing time and convenient dosage schedule.

The effect of orthopedic screw profiles on the healing time of femoral neck fracture

One possible treatment for femoral neck fractures, especially in young people, is the use of bone screws or Lug screws. The design of these implants requires taking into account the biocompatibility of materials, mechanical properties plus surface properties, and thread's geometric, as well as chemical properties, etc. Various profiles are designed for fracture fixation. The most famous of these profiles, which are introduced by the ISO standard, are HB, HC, and HD type profiles. This article investigates the performance of these profiles in reducing or increasing the healing time. This study is based on the rule of bone remodeling and using a set of three-dimensional computational (finite element) models. The study revealed that the HB profile outperformed the other two profiles. Meanwhile, HD profile was also better than HC profile.

Diabetic foot ulcer, the effect of resource-poor environments on healing time and direct cost: A cohort study during Syrian crisis

Diabetic foot ulcer (DFU) is one of the slowest healing wounds that hurt the human body. Many studies from developed countries are concerned about materials, procedures, and equipment that accelerate the healing time. In Sweden, the diabetic foot management costs around 24965$/patient. In this review, we would evaluate the healing time of DFUs during what is considered one of the worst humanitarian crisis of the 21st century. 1747 DFUs were studied from the main diabetic foot clinic in Damascus (2014-2019). We predicted many variables that could prolong the healing time. The cost according to these variables was also reported. The SINBAD Classification was performed to grade the severity of ulcers. We noticed that the median healing time for DFUs was 8 weeks. Almost half of these ulcers healed between 3 and 12 weeks. The time of healing for men was significantly longer than that for women. While the presence of infection doubled the median time of healing, the presence of peripheral artery disease doubled the mean of the direct health care cost. The location of the ulcer acted as another independent risk factor. In conclusion, DFUs face many barriers to heal during a crisis.The environment with resource-poor settings should be added to the traditional risk factors that delay the healing of DFUs for months or even years. More studies from disaster are as are needed to evaluate low-cost materials that could be cost effective in applying standard care of the diabetic foot.

Conservative Versus Surgical Management of Fifth Metatarsal Avulsion Fractures

Fifth metatarsal avulsion fractures are among the most common fractures seen by foot and ankle surgeons. Studies have centered around classification systems, but debate continues regarding surgical versus conservative treatment modalities. The present study focused on quantifying the time for healing fifth metatarsal base avulsion fractures. Specifically, we compared healing time, displacement, and incidence of nonunion among surgically managed and conservatively managed avulsion fractures. Surgically managed patients underwent either open reduction with internal fixation or closed reduction with percutaneous fixation. Conservatively managed fractures were immobilized with a below-knee cast or pneumatic walking boot. Fifty-one patient records (51 feet) were retrospectively compared for basic demographics, smoking, and diabetes status, presence of peripheral neuropathy, Stewart classification, amount of displacement, rate of nonunion, and radiographic healing time. The groups did not differ significantly based on age, sex, or the remaining clinical characteristics including time to consolidation. However, among the 31 conservatively managed patients, 11 (35.5%) developed an asymptomatic nonunion versus none among the 20 patients treated surgically (p = .004). All patients were asymptomatic at 1 year. This study provides insight into the time required for fifth metatarsal avulsion fractures to heal or become asymptomatic. The surgical management of these fractures helped to eliminate the risk of nonunion and helped ensure a timely return to preinjury activity. We recommend surgical management of any fifth metatarsal avulsion fracture displaced >2 mm. Both patients and physicians should have realistic expectations when making decisions regarding treatment modalities for fifth metatarsal avulsion fractures.

Use of Infrared Thermography for Assessment of Burn Depth and Healing Potential: A Systematic Review

INTRODUCTION

Burn wound depth assessments are an important component of determining patient prognosis and making appropriate management decisions. Clinical appraisal of the burn wound by an experienced burn surgeon is standard of care but has limitations. IR thermography is a technology in burn care that can provide a non-invasive, quantitative method of evaluating burn wound depth. IR thermography utilizes a specialized camera that can capture the infrared emissivity of the skin, and the resulting images can be analyzed to determine burn depth and healing potential of a burn wound. Though IR thermography has great potential for burn wound assessment, its use for this has not been well documented. Thus, we have conducted a systematic review of the current use of IR thermography to assess burn depth and healing potential.

METHODS

A systematic review and meta-analysis of the literature was performed on PubMed and Google Scholar between June 2020-December 2020 using the following keywords: FLIR, FLIR ONE, thermography, forward looking infrared, thermal imaging + burn*, burn wound assessment, burn depth, burn wound depth, burn depth assessment, healing potential, burn healing potential. A meta-analysis was performed on the mean sensitivity and specificity of the ability of IR thermography for predicting healing potential. Inclusion criteria were articles investigating the use of IR thermography for burn wound assessments in adults and pediatric patients. Reviews and non-English articles were excluded.

RESULTS

A total of 19 articles were included in the final review. Statistically significant correlations were found between IR thermography and laser doppler imaging (LDI) in 4/4 clinical studies. A case report of a single patient found that IR thermography was more accurate than LDI for assessing burn depth. Five articles investigated the ability of IR thermography to predict healing time, with four reporting statistically significant results. Temperature differences between burnt and unburnt skin were found in 2/2 articles. IR thermography was compared to clinical assessment in five articles, with varying results regarding accuracy of clinical assessment compared to thermography. Mean sensitivity and specificity of the ability of IR thermography to determine healing potential <15 days was 44.5 and 98.8 respectively. Mean sensitivity and specificity of the ability of FLIR to determine healing potential <21 days was 51.2 and 77.9 respectively.

CONCLUSION

IR thermography is an accurate, simple, and cost-effective method of burn wound assessment. FLIR has been demonstrated to have significant correlations with other methods of assessing burns such as LDI and can be utilized to accurately assess burn depth and healing potential.

The comparison of Nice knots and traditional methods as an auxiliary reduction-fixation technique in pre-contoured locking plate fixation for comminuted Robinson type 2B clavicle fracture: A retrospective study

Open reduction and pre-contoured locking plate fixation is a popular treatment option for displaced midshaft clavicle fracture. Lag screw and cerclage are 2 main intraoperative techniques to reduce and fix fragments. However, both lag screw and metallic cerclage have disadvantages. The doubled-suture Nice knot has been reported in many areas of orthopedic surgery for its effectiveness. This study aims to compare the outcomes of comminuted mid-shaft clavicle fractures reduced by Nice knots vs traditional techniques (lag screw or/and metallic cerclage) when bridged with pre-contoured locking plates.We retrospectively reviewed 101 patients (65 females and 36 males) diagnosed with midshaft clavicle fractures with at least one wedge fragment reduced by either Nice knots or traditional methods and bridged with pre-contoured locking plates between December 2016 and April 2019. Operation time, functional outcomes, pain, patient satisfaction, fracture healing, and complications were assessed at a follow-up of 12 to 40 months.The mean age of all the patients was 50.8 years. There were 52 and 49 patients in the Nice knot group and traditional group respectively, and no differences between 2 groups were found in general patient characteristics, fracture type, follow up and injury-to-surgery duration. The Nice knot group had significant less operation time (P < .01) than the traditional group (mean and standard deviation [SD], 78.6 ± 19.0 compared with 94.4 ± 29.9 minutes, respectively). For healing time, functional score, pain, satisfaction and complications, there were no significant differences between groups, despite the Nice knot group had slightly better results.Both Nice knots and traditional methods treated for comminuted Robinson type 2B clavicle fractures were effective and safe. And the Nice knots seemed to be superior with significant less operation time.

The efficiency of internal fixation with bone grafting at docking sites after bone transport for treatment of large segmental tibial bone defects

OBJECTIVE

To investigate the efficiency of internal fixation with bone grafting after bone transport for treatment in large-segment bone defects of the lower-limbs.

METHODS

This prospective study recruited 100 patients with lower limb tibial segmental bone defects, and based on a random number table they were divided into a control group (n=50, simple bone transport surgery) or an observation group (n=50, internal fixation with bone grafting at docking site after bone transport). The fracture healing time, bone healing index, external fixation time in both groups were compared. The knee function, joint range of motion, and the function of the ankle and hindfoot before and after surgery were also analyzed and compared between the two groups respectively, as well as the rate of complications in both groups was calculated.

RESULTS

Compared with the preoperative condition of patients, the Lysholm knee scale, ROM score, and AHS scores of patients in the two groups were significantly increased 10 months after surgery, moreover, those scores of the observation group were higher than that of the control group (P<0.05). The fracture healing time and external fixation time of patients were significantly declined in the observation group when compared to the control group, additionally, the bone healing index was also reduced significantly (P<0.05). When compared with patients in the control group, the ratios of bone healing and lower-limb functional recovery of patients in the observation group were significantly higher while the total complication incidence was decreased remarkably (P<0.05).

CONCLUSION

Internal fixation with bone grafting after bone transport can promote fracture healing, improve joint function, and reduce complications during treatment for a large segmental bone defects in the lower limbs.

Porcine Xenograft and Epidermal Fully Synthetic Skin Substitutes in the Treatment of Partial-Thickness Burns: A Literature Review

Background and Objectives: Porcine xenografts have been used successfully in partial thickness burn treatment for many years. Their disappearance from the market led to the search for effective and efficient alternatives. In this article, we examine the synthetic epidermal skin substitute Suprathel^® as a substitute in the treatment of partial thickness burns. Materials and Methods: A systematic review following the PRISMA guidelines has been performed. Sixteen Suprathel^® and 12 porcine xenograft studies could be included. Advantages and disadvantages between the treatments and the studies’ primary endpoints have been investigated qualitatively and quantitatively. Results: Although Suprathel had a nearly six times larger TBSA in their studies (p < 0.001), it showed a significantly lower necessity for skin grafts (p < 0.001), and we found a significantly lower infection rate (p < 0.001) than in Porcine Xenografts. Nonetheless, no significant differences in the healing time (p = 0.67) and the number of dressing changes until complete wound healing (p = 0.139) could be found. Both products reduced pain to various degrees with the impression of a better performance of Suprathel^® on a qualitative level. Porcine xenograft was not recommended for donor sites or coverage of sheet-transplanted keratinocytes, while Suprathel^® was used successfully in both indications. Conclusion: The investigated parameters indicate that Suprathel^® to be an effective replacement for porcine xenografts with even lower subsequent treatment rates. Suprathel^® appears to be usable in an extended range of indications compared to porcine xenograft. Data heterogeneity limited conclusions from the results.

Effect of vacuum sealing drainage on healing time and inflammation-related indicators in patients with soft tissue wounds

The aim of this study was to investigate the therapeutic effects of vacuum sealing drainage (VSD) on wound repair time and inflammation-related indicators in patients with soft-tissue wounds in comparison with traditional treatment. From January 2018 to January 2020, 130 enrolled patients with soft-tissue wounds were randomly divided into two groups: VSD group (65 cases) and routine dressing change (RDC) group (65 cases). The inflammation-related indicators including erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), white blood cell (WBC), and procalcitonin (PCT) of preoperative stage and postoperative day 3 (POD 3) and POD 7 were recorded. Wound healing was observed 3 and 7 days after treatment, and the clinical efficacy, changes in the wound (coverage rate and thickness of granulation tissue and bacterial clearance rate), wound-cleaning time, wound-healing time, and hospital stay time were recorded after treatment as well. No significant difference was observed in terms of the baseline between the two groups. On POD 3 and POD 7, CRP, WBC, and PCT levels in the VSD group were lower than those in the RDC group, while ESR levels were higher, with significant differences (P < .05). After treatment, the wound-cleaning time, wound-healing time, and hospital length of stay of the VSD group were all lower than those of the RDC group, with significant differences (P < .05). VSD has a significant effect on the treatment of patients with soft-tissue wounds, which can effectively shorten the time of wound healing and reduce inflammation-related indicators. Compared with traditional RDC, VSD is more worthy of clinical application.

Efficacy of Momiai in Tibia Fracture Repair: A Randomized Double-Blinded Placebo-Controlled Clinical Trial

Objectives: Momiai ( shilajit, mummy, mumie, or mineral pitch) has been used traditionally in different medical systems for the treatment of a variety of ailments since hundreds of years ago. It is a natural substance found in different rocky parts of the world, formed by plants, mineral, and animal remains gradually. There is also worthwhile evidence supporting its oral use for bone repair in Persian medicine. The aim of this study was to evaluate the efficacy and safety of momiai in tibia fracture healing. Design: This study is a randomized double-blinded controlled trial. Settings/Location: Three different hospitals in Tehran, Iran. Subjects: Patients with age range of 18-60 years admitted due to new tibia fracture were enrolled after meeting the inclusion criteria. Interventions: The patients were divided into two groups randomly and received two 500 mg capsules of momiai or placebo for 28 days. Outcome measures: The process of bone healing was assessed by frequent X-ray radiographies and adverse effects were recorded. Results: Totally, 160 patients participated in the study either in two equal intervention or placebo groups. There was no significant difference between groups in terms of demographic and descriptive data. At the end of the study, the mean time of tibial bone union was 129 days in the experimental group, while it was 153 days in the placebo group (p < 0.049). There was no significant difference in the reported adverse effects between the two groups (p = 0.839). Conclusions: The current study showed that oral consumption of momiai after tibial shaft fracture surgery could be a promising option to reduce the healing time.

Risk factor analysis on the healing time and infection rate of diabetic foot ulcers in a referral wound care clinic

OBJECTIVE:

Objectives. To determine the prevalence and risk factors for diabetic foot infection (DFI), and to identify factors associated with delayed wound healing of diabetic foot ulcer (DFU).

METHOD:

The retrospective study was performed in a referral wound care clinic in Hospital Kuala Lumpur. Data was collected from January 2014 to October 2016 on DFU patients who attended this clinic.

RESULTS:

Of the 340 patients (216 male and 124 female) DFU patients who attended the clinic (mean age: 58.1±10.8 years old), 41.5% presented with infection with a mean cross-sectional ulcer area of 21.5±33.2cm². Binary logistic regression analysis revealed that patients of Chinese ethnicity (OR: 3.39; 95%CI 1.49 to 7.70), with fasting blood glucose ≥7mmol/l (OR: 3.41; 95%CI 1.57 to 7.39), ulcer size ≥10cm² (OR: 2.90; 95%CI 1.45 to 5.82) and blood pressure ≥140/90mmHg (OR: 2.52; 95%CI 1.54 to 4.14) were more likely to develop DFI. The median healing time for patients with DFUs was three months. There were six variables identified as significantly associated with prolonged healing time of DFU, namely presence of infection (p<0.001), poor glycaemic control with fasting blood glucose ≥7mmol/l (p<0.001), high blood pressure ≥140/90mmHg (p<0.001), large DFU size ≥2cm² (p<0.001), history of amputation (p<0.005) and plantar location of the DFU (p<0.05).

CONCLUSION:

Large DFU size, poor glycaemic and blood pressure control are common risk factors for both DFU and DFI. Unexpected high prevalence and ethnicity risk factor for DFI urge more comprehensive primary and secondary preventative strategies to reduce its incidence.

The reality of routine practice: a pooled data analysis on chronic wounds treated with TLC-NOSF wound dressings

OBJECTIVE

A number of randomised controlled trials (RCT) have compared control groups with TLC-NOSF dressings (UrgoStart) on chronic wounds. Our aim was to determine whether the clinical trials' results translate into routine management of such wounds, by pooling the data from real-life observational studies.

METHOD

Observational studies, conducted in France and Germany, evaluating current practices in patients suffering from non-selected chronic wounds treated with a TLC-NOSF dressing were identified. Demographic data, baseline description of wounds and description of their evolution during treatment were extracted and combined. We used two main indicators of clinical outcomes to measure the impact of the TLC-NOSF dressing on this population: time to wound closure and time to 50% reduction of the Pressure Ulcer Scale for Healing (PUSH) score.

RESULTS

In total, data from 10,220 patients were included, with 7903 leg ulcers (LUs), 1306 diabetic foot ulcers (DFUs) and 1011 pressure ulcers (PUs). The overall closure rate was 30.8 % [95 % confidence interval (CI): 29.9-31.7 %]. While the country, patient age, and number of wounds were identified as independent prognosis factors of healing, the most significant were wound duration and baseline area. The delay in initiating TLC-NOSF dressings treatment was also found to be significant. Overall the average time to complete closure was 112.5 days [95%CI: 105.8-119.3] for LUs, 98.1 days [95 %CI: 88.8-107.5] for DFUs and 119.5 days [95%CI: 94.6-144.3] for PUs. Based on a subgroup analysis of the French cohort, time to closure is substantially shorter for wounds treated with the TLC-NOSF dressing as a first-line intervention compared with those where it has been prescribed as a second-line intervention.

CONCLUSION

Compared with available data on time to complete closure of chronic wounds managed by 'standard' care, the data from this pooled data analysis showed healing time is reduced, which is consistent with the results of RCTs on TLC-NOSF. That these data are in agreement with those from the RCTs is testimony to their generalisability and important for routine practice. This indicates that using TLC-NOSF dressings in routine wound management can reduce the healing time of LUs, DFUs and PUs. These data also suggest that the earlier the decision to use this dressing, the shorter the time to closure, whatever the severity and the nature of these chronic wounds.

A NEW TREATMENT MODALITY TO REDUCE ACUTE TONSILLITIS HEALING TIME

BACKGROUND AND OBJECTIVE

Acute tonsillitis is one of the most common reasons for application to otorhinolaryngology clinics. In the treatment of acute tonsillitis, supportive therapies are mostly used. As antibiotic therapy, penicillin or erythromycin can be used. The aim of this study is to decrease the clinical recovery time of acute tonsillitis by providing parenteral treatment and daily cleaning of tonsillar lesions.

MATERIAL AND METHODS

Patients with an age range of 15-60 years were included in the study. The patients were divided into two groups. The first group used an i.v. combination of ampicillin + sulbactam and the tonsillar membranes of patients were cleaned daily. The second group used only the i.v. combination of ampicillin + sulbactam.

RESULTS

Patients who received antibiotherapy and debridement had a clinical improvement of 90% on the 2nd treatment day and 95% on the 5th treatment day. The patients receiving only antibiotics had a clinical improvement of 65% on the 5th treatment day and 75% on the 7th treatment day. The recovery time of both groups was significantly different (p < 0.05).

CONCLUSION

The solution and technique used in this clinical study showed that patients with acute tonsillitis could recover in a very short time without any complications.

Propranolol versus steroids for the treatment of ulcerated infantile hemangiomas

BACKGROUND

There has been a paradigm shift from steroids to propranolol for the pharmacologic treatment of infantile hemangiomas (IH); however, the outcomes for ulcerated IH are not well studied. The purpose of this study was to compare the efficacy of steroids and propranolol specifically for ulcerated IH.

METHODS

A retrospective review was conducted on patients with ulcerated IH treated with propranolol or steroids at a single tertiary care institution between 2007 and 2014. Patient characteristics, hemangioma features, and outcomes, including time to heal and medication complications, were compared between propranolol and steroid patients.

RESULTS

There were 29 patients treated with propranolol and 23 with steroids. There were no significant differences in the two treatment groups including age, race, sex, size, or insurance status. There were more head/neck IH in the steroid group. There was no significant difference in the percentage of healed lesions (93 vs. 74%, P = 0.12) or the median time to heal (80 vs. 126 days, p = 0.21) between groups. Overall complication rates also did not vary between medications (24 vs. 44%, P = 0.14).

CONCLUSION

Propranolol is noninferior to steroids for the treatment of ulcerated IH; however, healing time is lengthy regardless of treatment. While side effect profiles differed between medications, the overall complication rate was similar.

Does Type 2 Diabetes Mellitus Affect the Healing of Bell's Palsy in Adults?

OBJECTIVES

Bell's palsy (BP) is defined as an acute facial weakness of unknown cause. Many factors affecting the healing of BP have been identified; 1 factor commonly considered relevant is the presence of type 2 diabetes mellitus. Our aim was to investigate the effects of diabetes on the healing of BP.

METHODS

Sixty patients with BP were followed up for 1 to 3 years and were divided into 2 groups, those with and those without type 2 diabetes. All were prescribed prednisone (initially 1 mg/kg per day, with a tapered dose reduction) and acyclovir (200 mg orally every 4 h, 5 times daily, for 5 days). Their recovery times were compared.

RESULTS

The healing times of the patients with and without diabetes did not differ.

CONCLUSIONS

Diabetes does not affect the severity, recovery rate from or healing of BP.

Surgical Management of Fifth Metatarsal Diaphyseal Fractures: A Retrospective Outcomes Study

Fifth metatarsal diaphyseal fractures are a common injury treated by foot and ankle surgeons. The limited data on this specific fracture type has promoted nonoperative treatment with immobilization. The primary objective of the present study was to record the radiographic healing time of fifth metatarsal diaphyseal fractures after surgical intervention and present the specific fracture characteristics. The medical records of a series of 64 patients with surgically managed fifth metatarsal diaphyseal fractures were retrospectively reviewed. The data collected consisted of radiographic healing times, fracture characteristics, and patient demographics. The mean average age at injury was 49.23 ± 15.35 years with greatest incidence in females at 73.44%. The mean healing time was 7.73 ± 4.74 weeks, with an overall complication rate of 6.25%. The fractures were classified into 2 specific categories according to the anatomic location. Type I fractures occurred in a significantly older population, were significantly longer in length, and healed faster. The mean displacement and angulation at injury was 3.20 ± 1.22 mm, and 5.89° ± 4.60°, respectively, for all fractures. Of the 64 patients, 1 (1.56%) experienced nonunion, 2 (3.13%) delayed unions, and no malunions. One patient (1.56%) underwent repeat operation for hardware removal. One case (1.56%) of superficial postoperative infection developed and was treated with oral antibiotics. We observed good surgical outcomes with minimal postoperative complications. We also identified 2 specific entities of fifth metatarsal diaphyseal fractures. On the basis of our results, we advocate surgical intervention even for minimally displaced diaphyseal fractures to maintain even weightbearing across the metatarsal parabola.

Pilonidal sinus: a comparative study of treatment methods

INTRODUCTION

Pilonidal disease is a very common anorectal problem without a clinical consensus on its optimal management.

OBJECTIVE

To compare the methods used by our clinic and determine the outcomes in relation to healing, hospitalization time and recurrence.

MATERIALS AND METHODS

We have studied all the cases of patients with pilonidal sinus that were treated surgically in our clinic from January 1, 1997 to December 31, 1999.

RESULTS

A total of 111 patients were treated of whom 92 (82,8%) were men and 19 (17,2%) were women. Ages ranged from 16 to 65 years with an average age of about 25,1 years. Of the 111 patients, 63 were treated with marsupializationand the remaining 48 were treated by excision (29 with open excision and 19 with the primary suture technique). One hundred and two (91,9%) patients were discharged from the hospital after the surgical procedure, while the remaining 9 patients were hospitalized for 24 hours. The healing time for marsupialization was 27,3 days, the primary suture technique was 11,7 days and the open excision method took 46,4 days. Recurrence was observed in 16 patients (14,4%). Recurrence appeared in 4 (6,35%) of the 63 patients subjected to marsupialization, 1 of the 29 patients subjected to open incision, and 11 (57,8%) of the 19 patients subjected to primary closure.

CONCLUSION

In the absence of inflammation and/or recurrence, marsupialization is the surgical method of choice as it has a low percentage of recurrence and an acceptably short healing period.In apparently large, inflamed and recurrent situations, open excision is preferred.

The Volume Behavior of Autogenous Iliac Bone Grafts After Sinus Floor Elevation: A Clinical Pilot Study

Iliac crest is still regarded as one of the most viable source of autogenous graft materials for extensive sinus floor elevation. Three-dimensional resorption behavior has to be taken into account in anticipation of the subsequent insertion of dental implants. We performed 3-dimensional volume measurements of the inserted bone transplants in 11 patients (6 women and 5 men; mean age = 2.3 years) who underwent bilateral sinus floor elevation with autogenous iliac crest grafts. In order to determine the respective bone graft volumes, cone-beam computerized tomography studies of the maxillary sinuses were carried out directly after the operation (T0), as well as 3 months (T1) and 6 months (T2) postoperatively. The acquired DICOM (Digital Imaging and Communications in Medicine) data sets were evaluated using suitable analysis software. We evaluated statistical significance of graft volumes changes using a linear mixed model with the grouping factors for time, age, side, and sex with a significance level of P = .05. 38.9% of the initial bone graft volume, which amounted to 4.2 cm(3), was resorbed until T1. At T2, the average volume again decreased significantly by 18.9 % to finally reach 1.8 cm(3). The results show neither age nor side dependency and apply equally to both sexes. Without functional load, iliac bone grafts feature low-volume stability in sinus-augmentation surgery. Further clinical and animal studies should be done to detect the optimal timing for implant placement.

Radio electric tissue optimization in the treatment of surgical wounds

Purpose

To report preliminary results with the tissue optimization (TO) treatment with a radio electric asymmetric conveyer (REAC) in promoting the repair of surgical wounds.

Patients and methods

Two subjects, a 54-year-old male with a tear bruise on the upper third of the leg and a 19-year-old female with a stab wound to the hand, were treated with 12 REAC-TO treatment sessions.

Results

In both patients, the wounds showed shorter healing time compared with the time usually required for similar wounds, and good repair quality.

Conclusion

REAC device with its specific treatment protocols may be an alternative therapy for wound healing.
