Treatment outcomes and loss to follow-up rate of male patients with gonococcal and nongonococcal urethritis who attended the sexually transmitted disease clinic: An 8-year retrospective study.

BACKGROUND: Poor follow-up compliance of patients with infectious urethritis is a recognized and serious public health problem in Thailand. AIM: The aim of this study was to determine treatment outcomes and loss to follow-up rate of male patients with gonococcal urethritis (GU) and non-GU (NGU) at a sexually transmitted disease (STD) clinic at Thailand's tertiary hospital. METHODS: This retrospective chart review of male patients who sought treatment at STDs Clinic, Siriraj Hospital, and who were diagnosed with GU and/or NGU was conducted during January 2007 to December 2014 study period. RESULTS: Two hundred and twenty-seven male urethritis patients were included in this study with a mean age was 29.5 years. GU and NGU were found in 120 (52.9%) and 107 (47.1%) of patients, respectively. Overall prevalence of GU and NGU during the 8-year study period at STD Clinic, Siriraj Hospital, was 8.6% and 7.8%, respectively. Ninety-six patients (42.3%) were lost to follow-up. Recurrent urethritis was found in 23.8% of patients, and HIV infection was identified in 11.6%. Mean age of patients lost to follow-up was 29 years. Compared with patients who attended every scheduled follow-up visit, men who have sex with men had a significantly lower rate of loss to follow-up (P = 0.012). CONCLUSION: Almost half of patients with GU or NGU were lost to follow-up, and one-quarter had recurrent urethritis. Fast and easy access to services that provide accurate diagnostic testing and effective treatment should be a public health priority to prevent complications and reduce rates of disease transmission.

Epidemiology, Clinical Characteristics, Sites of Infection and Treatment Outcomes of Mucocutaneous Candidiasis Caused by Non-Albicans Species of Candida at a Dermatologic Clinic.

BACKGROUND: Increasing numbers of mucocutaneous infection due to non-albicans species of Candida (N-CA) had been reported. Laboratory based studies showed multidrug resistance in N-CA population. OBJECTIVE: Demonstrate epidemiology, clinical characteristics, sites of infection, and treatment outcomes of mucocutaneous candidiasis caused by N-CA at a dermatologic clinic, including statistical evaluation data between N-CA and C. albicans infections. MATERIAL AND METHOD: This was a cross sectional study of outpatients with mucocutaneous infection due to Candida at Dermatologic clinic between January 2012 and June 2014. Vaginal candidiasis was excluded. Demographic, clinical, laboratory data, and treatment outcomes were collected. RESULTS: Among 760 patients presented with mucocutaneous candidiasis, 307 (40.4%) were infected with N-CA. The mean age (SD) of N-CA patients was 63.6 (10.4) years and 74.6% were female. The majority of N-CA cases were isolated from patients' nails (n = 293, 95.4%) while eight (2.6%) were detected from their skin, and six (2%)from oral mucosa. Comparison between N-CA and C. albicans, skin, and mucosa infection were significantly demonstrated in C. albicans groups (p < 0.001). Among nail infected patients, C. albicans infections had significant higher severity than the N-CA infection (p = 0.017). Median time to cure in N-CA population was 169 days, which had no significant difference from C. albicans groups (211 days, p = 0.499). CONCLUSION: Forty percent of mucocutaneous candidiasis was caused by N-CA. Nails were the most common sites of N-CA infections but N-CA was sometime found in skin and mucosa. Treatment outcomes of N-CA population were not significantly different from those of C. albicans groups.

Efficacy of 5% amorolfine nail lacquer in Neoscytalidium dimidiatum onychomycosis.

BACKGROUND: Amorolfine nail lacquer was mentioned as an effective treatment for non-dermatophyte nail infection. Onychomycosis that caused by Neoscytalidium dimidiatum is considered recalcitrant onychomycosis. OBJECTIVE: This study aimed to demonstrate efficacy and treatment outcomes of amorolfine nail lacquer in N. dimidiatum onychomycosis, compared with topical urea treatment. METHODS: This was a retrospective study of patients daiagnosed as N. dimidiatum onychomycosis at dermatologic clinic between April 2010 and August 2014. Clinical manifestations and laboratory results were collected. The evaluation included 50% improvement, which meant 50% decrease in subungual hyperkeratosis thickness from original untreated nails. Mycological cure is defined by negative result of both KOH and fungal culture. Moreover, complete cure means infected nails return to its normal condition as well as KOH and fungal culture yield negative results. RESULTS: Among 53 outpatients of N. dimidiatum infection, 28 (52.8%) were treated by amorolfine nail lacquer and other 26 (47.2%) by conventional topical urea cream with occlusion. Comparison between amorolfine and topical urea groups, mycological cure rate was significantly shown in amorolfine group (89.3% vs. 32%; p < 0.0001). Moreover, 50% clinical improvement and complete cure rate of amorolfine group were significantly higher than those of topical urea group (85.7% vs. 48%; p = 0.003 and 50% vs. 20%; p = 0.023, respectively). Median time to mycological cure and complete cure in amorolfine group was significantly shorter than that of topical urea group (p = 0.001 and p = 0.013, respectively). CONCLUSION: This study supported that amorolfine nail lacquer provided promising efficacy in the treatment of Neoscytalidium onychomycosis as a novel monotherapy regimen which were superior to topical urea cream with occlusion in every aspect.

Tinea capitis caused by Trichophyton tonsurans presenting as an obscure patchy hair loss due to daily antifungal shampoo use.

Tinea capitis is unusual and often misdiagnosed in healthy adults. We report a case of a healthy woman with a several-year history of asymptomatic, bizarre-shaped, non-scarring alopecia. She had used over-the-counter ketoconazole shampoo regularly for a long time. An initial potassium hydroxide preparation showed negative result for fungal organism. The scalp biopsy revealed endothrix infection, and dermoscopic examination demonstrated the comma hair and corkscrew hair signs. The fungal culture showed Trichophyton tonsurans. The daily use of antifungal shampoo could be the important factor to conceal clinical and laboratory findings for diagnosis of T. tonsurans tinea capitis in our case, which required high clinical suspicion and histopathology and dermoscopic examinations.

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.
