A double-blinded, randomized, split-side, vehicle-controlled study of the efficacy of cleanser containing Acanthus ebracteatus Vahl., Suregada multiflora, and Acacia concinna in patients with atopic dermatitis: A pilot study.

BACKGROUND: Barrier repair therapy is the key management approach for both eczematous and non-lesional skin of atopic dermatitis. The use of appropriate cleansers to enhance skin hydration is an adjunctive treatment that increases topical drug penetration. Anti-inflammatory properties of various medicinal plants in tropical Asia have been reported. OBJECTIVE: Investigate the efficacy of herbal cleanser containing a combination of herbal extracts from Acanthus ebracteatus Vahl., Suregada multiflora, and Acacia concinna on seemingly intact skin in patients with atopic dermatitis by measuring improvements in the skin barrier function. METHODS: This 2-week pilot study was a split-side, randomized, double-blinded, vehicle-controlled trial. All patients (n = 30) were asked to use both a cleanser with an active formulation containing the herbal extracts and a vehicle- controlled cleanser on each side of mid-volar forearm. Biophysical assessments including transepidermal water loss (TEWL), skin hydration, skin pH, and skin roughness were performed at baseline and upon study completion. RESULTS: Compared to baseline, the median percentage change in TEWL at the end of the study was significantly greater for the active side 10.4 (-19, 20.7) g/m2h than the control side -13.2 (-28.7, 9.1) g/m2h; p = 0.01. The median percentage change of skin hydration, skin pH, and skin roughness of the active side compared to the control side had no a statistical significance. CONCLUSIONS: This cleanser is beneficial when used as adjunctive therapy. Further studies should evaluate its anti- sinflammatory properties in the remedy or active phase of atopic dermatitis or other inflammatory skin diseases.

Efficacy and Safety in 1% Clotrimazole Powder, Adjuvant Therapy in Patients with Superficial Fungal Cutaneous Infection in Intertriginous Areas.

Background: Superficial fungal cutaneous infection is commonly found in intertriginous area. Objective: To assess 1% clotrimazole powder (1% CP) efficacy for adjuvant treatment of superficial fungal cutaneous infection in intertriginous areas. Material and Method: The study performed as an open-label, randomized, comparative study for evaluating the effects of 1% clotrimazole cream (1% CC) with 1% CP in patients infected with dermatophytes (DMPs) or Candida spp. in intertriginous area, comparing to patients treated with 1% CC as control by demonstrating complete cure rate at 4, 8, and 12 weeks as well as relapse rates during a 24-week period including patient satisfaction. Results: Sixty-seven patients with mean age of 54.6 years were included in this study. Of those, 61.2% were males. Thirty-five patients were infected with DMPs and 32 with Candida spp. The complete cure rates of experimental group were significantly higher than the control group, as observed within four weeks (p = 0.01), especially for dermatophyte infection (p = 0.039). Two cases had recurrent candidiasis in the control group. In both groups, relapse up to 24 weeks were not statistically different. Additionally, there was no difference in patients' satisfaction towards convenience of drug application. Conclusion: Using of the 1% CP could be suggested as an adjuvant therapy and possibly preventive agent for superficial fungal cutaneous infection in intertriginous areas.

WILLINGNESS TO PAY, QUALITY OF LIFE, AND KNOWLEDGE ON HERPES ZOSTER AMONG THAI PATIENTS PRIOR ZOSTER VACCINE ERA.

Herpes zoster is a devastating condition affecting patients' wellbeing. Policy on zoster vaccine in developing countries needs more data on the disease burden. This study was designed to assess willingness to pay, quality of life, and the patients' knowledge on herpes zoster disease. All of the patients were asked to complete questionnaires about the willingness to pay for zoster treatment using the Dermatology Life Quality Index (DLQI) questionnaires in Thai version and basic knowledge about herpes zoster. The demographic and clinical data were all recorded. Eighty-two from one hundred and eighteen patients in this study were female (69.5%), and the mean (SD) age was 57.6 (14.9) years. The median of their willingness to pay for zoster treatment was THB500 (range of THB50-10,000) or only 4.2% of median income per month. The mean of total DLQI score (SD) was 10.7 (6.2), which indicated moderate to severe impact on quality of life. From multiple linear regression analysis, three factors were related to inferior patients' quality of life including facial involvement (regression coefficients, b=4.789, p=0.001), presence of zoster complications (b=5.018, p=0.001) and advanced pain score (b=0.883, p<0.001). Moreover, more than half of them still had mistaken knowledge about the disease.

Distinct characteristics of Scytalidium dimidiatum and non-dermatophyte onychomycosis as compared with dermatophyte onychomycosis.

Studies of demographic data, predisposing factors and clinical manifestations of non-dermatophyte mold (NDM) infection particularly in Scytalidium spp. have been limited. This study aimed to compare these data between dermatophytes (DMP) and NDM onychomycosis with statistical analysis. This was a retrospective chart review of outpatients with onychomycosis in the Nail Clinic of Department of Dermatology between January 2011 and December 2013. A total of 237 patients who had presented with onychomycosis were included. One hundred and eighty patients (75.9%) were infected with DMP: Trichophyton mentagrophytes, 46.8%; and Trichophyton rubrum, 28.3%. Of patients who had NDM onychomycosis, 17.3% were Scytalidium dimidiatum and 6.8% were Fusarium spp. Comparing the DMP and NDM groups, family history of superficial fungal infection was significantly demonstrated in the DMP group. Approximately 50% of patients in both groups had feet infections. However, no patients with NDM onychomycosis had fungal glabrous skin infection at other sites beyond the feet that was statistically different from cases with DMP onychomycosis. In conclusion, The distinct characteristic of patients with NDM onychomycosis was absence of fungal glabrous skin infection in areas other than the feet. This was statistically different from DMP.

Clinical characteristics of hypertrophic herpes simplex genitalis and treatment outcomes of imiquimod: a retrospective observational study.

OBJECTIVE: Atypical presentations of herpes simplex genitalis are becoming more frequent. The aim of this study was to investigate the atypical clinical manifestations and treatment of this infection. METHODS: The charts of patients with herpes simplex genitalis who attended our clinics between January 2009 and December 2013 were reviewed retrospectively. RESULTS: Of 294 patients, 147 (50%) were male with a mean (standard deviation, SD) age of 48.3 (16.8) years. An ulcerative lesion was the most common symptom (48.3%), followed by vesicle clusters (36.4%). The mean duration of symptoms at first visit was 6 days. Oral acyclovir was administered to 87.6% of patients. Hypertrophic manifestations were observed in 4.8% (14/294) of patients; 50% (7/294) were male, with a mean age of 44.5 (SD 9) years. All patients with hypertrophic manifestations were infected with HIV. Hypertrophic manifestations had a mean duration of onset of 53.3 days. Acyclovir was prescribed to 11 (78.6%) patients. The mean duration to cure was 40.9 days. Topical imiquimod was given in six resistant cases (42.9%) as adjunctive therapy. CONCLUSIONS: Atypical manifestations of herpes simplex genitalis require careful consideration because their frequency is rising, particularly in patients with HIV infection. Although acyclovir is important in their treatment, imiquimod provides an additional benefit in resistant cases.

Clinical and epidemiological characteristics of patients with syphilis: 5 year-case study from Thailand.

BACKGROUND: Syphilis has been increasing dramatically worldwide since 2000, especially among men who have sex with men (MSM), and in those with human immunodeficiency virus (HIV) infection. However most previous reports studied about prevalence and riskfactors ofsyphilis in MSMpopulation without statistical comparison with non-MSMpopulation. OBJECTIVE: The present study aimed to describe epidemiological trends, clinical manifestations, laboratory investigation, treatment, and HIV co-infection in patients diagnosed with syphilis, including statistical evaluation these data between MSMand non-MSM as well as HIV and non-HIVpopulations. MATERIAL AND METHOD: This was a retrospective medical records review ofpatients diagnosed with syphilis who attended Sexual Transmitted Diseases (STD) clinic between January 2008 and December 2012. Demographic data, clinical manifestations, HIVstatus, VDRL titer; and treatment regimens were collected. RESULTS: Of the 922 patients that attended the STD clinic, 143 syphilis patients were recruited with an overall prevalence of 15.5%. Twenty-six patients were MSM and 31 were HIV infected patients. Prevalence rate of syphilis in MSMand HIV infected patients were 2.8% and 3.4%, respectively. Prevalence had upward trend that startedfrom 2008 and reachedpeak in 2011. When taking MSMinto account, MSMsignificantly had younger age than non-MSM Early stage ofsyphilis, VDRL titer higher than 1:32 at diagnosis, and MSMpopulation were significantly associated with HIV-positivity among syphilis patients. Regarding treatment ofsyphilis, median time to cure syphilis was 117 days (95% confidence interval = 93-141). Treatment regimen, MSM and HIVco-infection did not significantly show influence on duration to cure. CONCLUSION: Prevalence ofsyphilis has been continuously increasing. MSM with syphilis significantly associated with younger age. Moreover, early stage of syphilis, VDRL titer higher than 1:32, and MSMpopulation were significantly related with HIVinfection. Treatment regimen, MSM and HIVco-infection did not significantly show influence on duration to cure.
