Polyphenol rich mung bean (Vigna radiata) yogurt for obesity prevention

This study was aimed to obtain yogurt formula rich in antioxidant phenolic and soluble protein of mung beans. Mung beans were washed, soaked, and then drained. With a ratio of 1:8, mung-beans and water, blended, and then filtered to produce mung beans juice. Mung beans yogurt (Mungbe-Yo) were made with the proportion of mung bean juice and skim milk were 100:0; 95:5; 90:10, and 85:15, before added with sugar as much as 10%, pasteurized in a 70°C temperature for 20 mins. After that, each Mungbe-Yo formula was cooled to 45°C, then added lactic acid bacteria (LAB) as a starter, as much as 2% and 4%, followed by incubation at room temperature for 24 hrs. Sensory tests included color, taste, flavor, and viscosity were performed by fifty-five panelists on a 5-point score basis. Antioxidant phenolic content was measured using the Folin-Ciocalteu method, while soluble protein was using the Lowry method. The highest score and most likable color, flavor, viscosity, and taste by panelists were formula P3B2, it was not different significantly with P3B1, P2B1, P2B2, and P1B2 (p>0.05). The proportion of mung bean juice-skim milk and LAB significantly affected the total phenolic and soluble protein (P<0.05), meanwhile its interaction was also statistically significant (P<0.05). Using effectivity index, the best Mungbe-Yo formula according to its total phenol and soluble protein content, as well as sensory was P3B1 formula, which was 85% mung bean juice, 15% skim milk and 2% LAB, containing phenolics and soluble protein were 525.958±48.9 mg GAE/L and 43.179±1.87%, respectively. Mungbe-Yo is suitable for individuals with obesity.

Three different consecutive manifestations of morphoeic BCC in the same patient: presenting first as ectropion, then entropion, and finally medial canthal dystopia with epicanthus inversus

Morpheaform basal cell carcinoma (BCC) can cause diagnostic difficulty due to an atypical clinical presentation. Successful treatment requires a high index of clinical suspicion together with an early confirmatory biopsy. We present the case of an 81-year-old lady with a delayed diagnosis of morphoeic BCC due to an unusual presentation of evolving lid malposition, and we highlight the limitations of a punch biopsy in diagnosing atypical lesions. An appropriate biopsy technique is vital, with consideration for repeat biopsies when necessary, especially if the clinical picture is changing over time.

Penile colloid degeneration

Colloid degeneration is a rare but well-recognized entity, usually occurring on chronically sun-exposed skin. We report a case occurring on penile skin with no history of such exposure.

Successful use of a thermoplastic dressing in two cases of the trigeminal trophic syndrome

Treatment of trigeminal trophic syndrome is challenging and often unsatisfactory, particularly in patients with cognitive impairment. We report the novel use of a thermoplastic dressing in two patients with trigeminal trophic syndrome. Use of the dressing resulted in successful healing of ulceration in both patients, which has been maintained in the short term, representing a simple and economical therapeutic option in the management of this difficult condition.

Intraindividual, right-left comparison of topical methyl aminolaevulinate-photodynamic therapy and cryotherapy in subjects with actinic keratoses: a multicentre, randomized controlled study

BACKGROUND

Actinic keratosis (AK), the most common premalignant skin condition, can represent a management challenge. Treatment should not only be effective, but also well tolerated and allow for good cosmesis on typical sun-exposed highly visible body sites.

OBJECTIVES

The primary objective was to compare the lesion response and subject preference for topical methyl aminolaevulinate (MAL)-photodynamic therapy (PDT) vs. cryotherapy for the treatment of AK.

METHODS

In this 24-week, multicentre, randomized, intraindividual (right-left) study, subjects received both one treatment session of MAL-PDT and a double freeze-thaw cryotherapy; the treatments were randomly allocated to either side of the face/scalp. Lesions with a noncomplete response were retreated after 12 weeks. The primary assessments were the subject's overall preference and lesion response at week 24. Secondary assessments included lesion response at week 12, cosmetic outcome, subject and investigator cosmetic outcome preference at week 24, and investigator overall preference at week 24. Skin discomfort and adverse events were also evaluated.

RESULTS

In total, 119 subjects with 1,501 lesions were included in the study. At week 12, treatment with MAL-PDT resulted in a significantly larger rate of cured lesions relative to cryotherapy (percentage lesion reduction from baseline: 86.9% vs. 76.2%; P < 0.001). At week 24, both treatment groups showed a high rate of cured lesions (89.1% for MAL-PDT vs. 86.1% for cryotherapy; P = 0.20; 95% confidence interval: -1.62 to 7.67). Results for subject and investigator preferences as well as cosmetic outcome favoured MAL-PDT. Both treatment regimens were safe and well tolerated.

CONCLUSIONS

The present study shows that, when treated with both MAL-PDT and cryotherapy, subjects significantly prefer MAL-PDT treatment for AK. MAL-PDT is an attractive treatment option for AK, with comparable efficacy and superior cosmetic outcomes compared with double freeze-thaw cryotherapy.

Study of patient-reported morbidity following V-beam pulsed-dye laser treatment of port wine stains

The V-beam pulsed-dye laser (PDL) (595 nm) has gained popularity in the treatment of port wine stains (PWS). It uses longer pulse durations than the standard flashlamp-pumped pulsed-dye laser (FPDL) (585 nm) and has an in-built cooling system to protect the epidermis. This should, theoretically, reduce the treatment-associated side effects, including discomfort. The aim of this questionnaire-based study was to confirm the clinical impression that V-beam PDL is well tolerated. The results were compared with a historical group of 62 PWS patients treated with FPDL. Fifty-one patients took part in the current study. Only 35.7% (vs. 81% in the historical comparison group) required topical anaesthetic prior to laser treatment. A shortening in the duration of bruising (8 vs. 10 days) and of symptoms such as burning and tightness (3 vs. 10 days) was recorded. Lifestyle change after treatment was recorded by fewer patients (39 vs. 57%). We conclude that V-beam PDL is better tolerated than FPDL when used at therapeutic levels in patients with PWS.

Educating patients about malignant melanoma: computer-assisted learning in a pigmented lesion clinic

This prospective controlled study aimed to evaluate the effectiveness and acceptability of a computer program (CAL) designed to educate patients about skin protection including signs of melanoma. Two hundred and twenty-seven patients were recruited either from the Pigmented Lesion Clinic (PLC) or the Orthopaedic Fracture Clinic (OFC). A baseline measure of anxiety was obtained and subjects were allocated to either non-interactive, interactive or control conditions. Measures of anxiety and knowledge about malignant melanoma and skin protection were obtained prior to discharge from the clinic and knowledge was assessed again at 1-week follow-up. Results indicate that, although anxiety in the PLC subjects decreased significantly more than in the OFC patients, there was no significant effect of intervention. There was a significant effect of intervention on knowledge (F = 81.06, d.f. 2, 218, P < 0.0001) with participants having better knowledge on leaving the clinic in the interactive CAL condition than in both the Non-interactive condition and control. Non-interactive CAL was associated with higher knowledge than control. Knowledge gains were maintained at 1-week follow-up.

Combination treatment with methotrexate and cyclosporin for severe recalcitrant psoriasis

An increasingly important approach to the management of patients with severe psoriasis is the concurrent use of two systemic treatments. Previous guidelines have advised against the use of methotrexate and cyclosporin in combination. We report the successful use of a combination of methotrexate and cyclosporin in the treatment of 19 patients with severe, recalcitrant psoriasis, 15 of whom had psoriatic arthropathy. Most patients had previously received two or more systemic treatments. Before combination treatment was started nine of the patients were taking methotrexate and 10 were taking cyclosporin at the maximum tolerated doses. The duration of combination treatment was bimodally distributed, with seven patients having short-term treatment (mean +/- SD duration 18. 9 +/- 15.7 weeks) and 12 patients having long-term treatment (mean +/- SD duration 193.2 +/- 160.6 weeks). Those patients who received short-term treatment did not develop any evidence of toxicity from either agent. Of those patients on long-term treatment, three developed mild impairment of renal function that returned to normal following a reduction in dose of cyclosporin, and three had impairment of renal function (following long-term cyclosporin monotherapy) that improved, but did not normalize, following a reduction in dose of cyclosporin. In each case, combination treatment for psoriasis resulted in good control of both skin and joint problems using lower doses of each agent than would have been used for monotherapy. We conclude that the combination of methotrexate and cyclosporin is an effective treatment for this group of patients.

Sweet's syndrome and malignancy in the U.K

Acute febrile neutrophilic dermatosis (Sweet's syndrome) is reported to be a marker for underlying malignancy. Much of the evidence for this is based on case reports, small series of cases and reviews of the literature. In order to clarify the association with malignancy and determine the common clinical features of Sweet's syndrome, we reviewed the case notes of patients presenting to six dermatology units in the U.K. Eighty-seven cases of histologically proven Sweet's syndrome were reviewed. Fourteen patients (16%) developed associated malignancy, predominantly haematological, two patients (2%) had a history of previous malignancy and four patients (5%) had premalignant conditions (monoclonal gammopathy, two: myelodysplasia, two). Malignancy developed up to a year after presentation with Sweet's syndrome. Patients with associated malignancy were more likely to be anaemic (P < 0.01) at presentation, had a lower mean platelet count (207 x 10(9)/L vs. 332 x 10(9)/L; P < 0.003) and were, on average, older (59 years vs. 49 years; P = 0.002). Contrary to previous reports, a greater percentage of females developed malignancy than males.

Graft-versus-host disease-like eruption in a patient with non-Hodgkin's lymphoma

Graft-versus-host disease (GVHD) is most commonly seen as a complication of bone marrow transplantation, although it can occur whenever tissue or blood products are given whereby immunologically competent donor lymphocytes react against host tissues. A 65-year-old man with non-Hodgkin's lymphoma developed a severe widespread erosive eruption of the skin and mucosal surfaces. Clinically and histologically it was identical to cutaneous GVHD even though the patient had never received tissue or blood products. He failed to respond to conventional therapy for GVHD, but his skin improved significantly on treating his underlying lymphoma, which eventually proved fatal. There are two previous reports of GVHD associated with malignancy but we believe this to be the first case secondary to a lymphoma.

Treatment of severe atopic dermatitis in childhood with cyclosporin

Cyclosporin has been shown to be effective in the treatment of adult atopic dermatitis, but there are no clinical trials evaluating its use in childhood. Atopic dermatitis is more common in children and the severe form can be associated with considerable morbidity. We report on 18 children with severe refractory atopic dermatitis who have been treated with cyclosporin on an open basis. The drug was given at an initial daily dose of 5 or 6 mg/kg and in some patients the dose was reduced according to response. Sixteen patients showed a good or excellent response to treatment, one a moderate response and one patient failed to improve. The treatment was well tolerated and there were no significant changes in serum creatinine or blood pressure. Long remission after withdrawal of treatment was seen in some patients, although most relapsed within a few weeks. We suggest that cyclosporin is an effective and safe short-term treatment for severe atopic dermatitis in childhood.

The under-reporting of skin disease in association with squamous cell carcinoma of the vulva

Histology sections from 61 cases of squamous cell carcinoma (SCC) of the vulva presenting after 1988 were reviewed for evidence of associated epithelial abnormality. Of the 50 patients with epithelium adjacent to the tumour, 24 had histological evidence of lichen sclerosus (LS), 20 of severe vulvar intraepithelial neoplasia (VIN 3), 22 of human papilloma virus (HPV) infection and three of lichen planus (LP). The clinical records and the original histology report were also subsequently reviewed and with the exception of VIN 3, these disorders were poorly reported by both clinicians and pathologists. Lichen sclerosus was diagnosed clinically in only two of the 36 hospital records available for inspection. Old terminology was used to describe some patients with epithelial disease (erythroleucoplakia in one patient with LS, leucoplakia in two patients with LS and one with LP). This study demonstrates the need to adopt standard nomenclature and increase the awareness of epithelial disease associated with SCC of the vulva among clinicians and pathologists.

Cyclosporine in severe childhood atopic dermatitis: a multicenter study

BACKGROUND

Severe atopic dermatitis (AD) remains difficult to treat. Cyclosporine is effective in adults but has not previously been investigated in children with AD.

OBJECTIVE

The aims were to investigate the efficacy, safety, and tolerability of cyclosporine in severe refractory childhood AD.

METHODS

Subjects 2 to 16 years of age were treated for 6 weeks with cyclosporine, 5 mg/kg per day, in an open study. Disease activity was monitored every 2 weeks by means of sign scores, visual analogue scales for symptoms, and quality-of-life questionnaires. Adverse events were monitored. Efficacy and tolerability were assessed with five-point scales.

RESULTS

Twenty-seven children were treated. Significant improvements were seen in all measures of disease activity. Twenty-two showed marked improvement or total clearing. Quality of life improved for both the children and their families. Tolerability was considered good or very good in 25 subjects.

CONCLUSION

Cyclosporine may offer an effective, safe, and well-tolerated short-term treatment option for children with severe AD.

Pellagra complicating Crohn's disease

We report a 53-year-old patient with clinical features of pellagra as a complication of Crohn's disease. His symptoms improved rapidly on taking oral nicotinic acid and vitamin B complex. We suggest the paucity of reported cases of pellagra in Crohn's disease is a reflection of poor recognition of this complication.

Severe halogen acne due to a trifluoromethylpyrazole derivative and its resistance to isotretinoin

We report a case of severe chloracne, with systemic involvement, following occupational exposure to dihydrotrifluoromethylphenyl benzothiopyranopyrazolone, which, to our knowledge, has not been previously reported as a cause of chloracne. Aggressive drug treatment, including high-dose oral isotretinoin was of limited benefit in suppressing the disease activity.

Split skin grafting on severely damaged skin. A technique using absorbable tissue adhesive

BACKGROUND

Patients with severely damaged skin are more likely to develop skin malignancies. However, suturing following excision of tumors is difficult due to their fragile skin.

OBJECTIVE

To evaluate the effectiveness of a technique using butyl-2-cyanoacrylate tissue adhesive in split skin grafts in patients with severely damaged skin.

METHOD

The technique was used in 19 patients with 24 skin tumors. Two patients also had multiple skin biopsies to assess the biodegradability of the adhesive.

RESULTS

Split skin grafts were applied successfully in all patients. The adhesive was completely absorbed without a foreign body reaction within 6 months.

CONCLUSION

We recommend the use of butyl-2-cyanoacrylate in split skin grafting patients with severely damaged skin.

Dermatomyositis associated with malignant melanoma--case report and review of the literature

Dermatomyositis (DM) is a connective tissue disorder characterized by cutaneous and muscle involvement. It is a well recognized paraneoplastic syndrome and has been linked with malignancy in 15-34% of adult patients. The course of DM in such patients usually correlates closely with the activity of the underlying malignancy. We report a patient who developed DM 4 years after excision of a malignant melanoma (MM) from the back and 1 year before the diagnosis of metastatic disease. A literature review revealed that the association of dermatomyositis with MM is rare and consistent with a dismal prognosis.

Primary anetoderma: phagocytosis of elastic fibres by macrophages

We report a 22-year-old female with a 2-year history of increasingly numerous well-circumscribed, asymptomatic skin lesions. The clinical and histological features were consistent with anetoderma and investigations failed to reveal any associated underlying disorders. Electron microscopy of abnormal skin showed phagocytosis of elastic fibres by macrophages. Although the aetiology of primary anetoderma remains unknown, this finding suggests that phagocytic destruction of elastic fibres plays a major role in its pathogenesis.

Bacitracin: a significant sensitizer in leg ulcer patients?

We report the results of patch testing 85 patients with either long-standing venous ulceration or eczema complicating their leg ulcers. As previously reported, lanolin and its derivatives and topical antibiotics were the most frequent sensitizers. However, unlike previously published data, we found bacitracin to be the most potent sensitizer of all topical antibiotics tested. There were no positive reactions in a control group of patients, although we were unable to repeat the patch tests in patients with a positive reaction to bacitracin. In the past 10 years, our department has used a proprietary mixture of polymyxin and bacitracin in treating infected leg ulcers and other dermatoses. It is therefore possible that chronic usage of topical bacitracin on leg ulcers carries a significant risk of contact sensitization.

PUVA and methotrexate therapy of psoriasis: how closely do dermatology departments follow treatment guidelines? Psoriasis Audit Workgroup of the British Association of Dermatologists

Following publication of treatment guidelines for patients with psoriasis, a six-centre audit was undertaken to assess current therapeutic practice for two second-line treatments, PUVA and methotrexate. The audit consisted of random sampling of casenotes by external auditors from a paired dermatology department, and assessment by questionnaire. One hundred and eight PUVA and 118 methotrexate casenotes were audited. The commonest indications for treatment were: (a) failure of tropical therapy--PUVA (mean 81% of casenotes), methotrexate (84%); (b) repeated hospital admissions--PUVA (16%), methotrexate (25%). For both PUVA and methotrexate, some aspects of treatment were well documented: PUVA--psoralen dosage (91%), response to PUVA (89%), cumulative lifetime UVA dosage (81%); methotrexate--pretreatment assessment of full blood count (91%), urea and electrolytes (85%), liver function tests (84%). For other aspects documentation was less complete: PUVA--no documentation of presence/absence of skin cancer history (66%), note of photoactive drugs (32%); methotrexate--concurrent medication (69%), history of presence/absence of liver disease (36%). Another aspect which was poorly documented in both PUVA and methotrexate notes was whether advice on contraception/fertility had been given. There was no indication in 29 of 32 casenotes of females of child-bearing age receiving PUVA, and 52 of 63 case notes of relevant patients on methotrexate. This project has demonstrated that formal, multicentre audit based on published guidelines is a practical proposition.

Carbamazepine-induced anticonvulsant hypersensitivity syndrome--pathogenic and diagnostic considerations

Two epileptic patients developed an infectious mononucleosis-like illness which subsequently proved to be a carbamazepine-induced anticonvulsant hypersensitivity syndrome. Patch testing to carbamazepine 3 years later was positive in the one patient tested and negative in normal controls. The second patient died a few weeks after the illness, secondary to long-standing cardiac disease without having undergone patch testing. A skin biopsy was, however, consistent with an immune complex mediated drug reaction. Patch testing for systemically administered drugs is generally believed to be of little value in diagnosing drug allergies. However, we reinforce a previous suggestion that this investigation may be helpful in some cases of anticonvulsant hypersensitivity syndrome caused by carbamazepine. The pathogenic role of type 3 and 4 hypersensitivity is also discussed.

Case report: mediastinal lymphadenopathy in eosinophilic pneumonia

Chronic eosinophilic pneumonia is a relatively rare disorder characterized radiologically by non-segmental homogenous consolidation in the lung periphery [1]. We present a patient who had marked mediastinal lymphadenopathy as well as the more typical radiological features, which resolved rapidly with treatment.

A comparison of the effect of viscosity on the precorneal residence of solutions in rabbit and man

The precorneal drainage of radiolabelled solutions containing polyvinyl alcohol (PVA) or hydroxypropyl methylcellulose (HPMC) have been measured in rabbit and man by gamma scintigraphy. Concentration of the polymers was varied to produce solutions with a viscosity range between 10.2 and 102 mPas. Solution drainage was faster in man than in the rabbit with a more pronounced effect of viscosity. Significant retardation of drainage in man was noted at the higher polymer concentrations (0.9% HPMC or 5.85% PVA).
