Onychomycosis contributes as many as half of all nail disorder cases. In 2017, the incidence of onychomycosis was 15% of all dermatomycosis cases at our hospital, a tertiary hospital in Indonesia, with only 25% of the patients achieving mycological cure. This study aims to identify the prognostic factors influencing the treatment outcome of onychomycosis Candida. This is a retrospective study, using data obtained from outpatient registry at our hospital. Fifty‐four onychomycosis patients were included in this study. Potential prognostic factors were analysed by STATA15.0. Retrospective analysis with cox proportional‐hazard was used to measure the contribution of each variable to the treatment's outcome. Onset of disease, history of nail disorder, and site of infection were not associated with mycological cure (P > .05). Based on retrospective analysis, age[odds ratio (OR)1.46; 95% confidence interval (CI)1.07‐2.03], onset of disease (OR 1.14; 95%CI 1.11‐1.17), comorbidities (OR 1.07; 95%CI 1.03‐1.11), type of onychomycosis (OR 1.08; 95%CI 1.05‐1.16), site of infection (OR 1.12; 95%CI 1.04‐1.22) and number of infected nails (OR 1.50; 95%CI 1.25‐1.68) were significantly associated with poor treatment outcome, while type of treatment and type of systemic agents showed no significant association with the outcome. Kaplan‐Meier curves showed that subjects elderly age and more than 3 infected nails had the lowest median survival. Elderly, longer onset, presence of comorbidities, multiple sites of infection, and high number of infected nails can affect the mycological cure negatively. Unstandardised treatment was associated with the mycological cure despite not affecting the prognosis. Therefore, the management's goal is to identify these specific prognostic features.

Scabies is difficult to treat in some settings. By observation, it is highly prevalent among students of religion-affiliated boarding schools in Indonesia. Treatment often results in temporary relief. It is known that treatment alone will fail if personal hygiene and environment problems are not addressed. The aforementioned boarding schools have certain challenging characteristics, and several studies have found they might influence those problems. Our study aimed to specify and describe the characteristics to prepare future mass treatment in tackling with the problems. The study recruited and interviewed 105 students of a boarding school located in West Java region. The problems identified were sharing clothes/prayer attire among students, infrequent washing of clothes, availability of hot water, sharing beds, lack of bed sheet, and the presence of scabies among friends and siblings at home. A successful treatment plan must provide means to improve these habits.

Introduction: Seborrheic dermatitis (SD) is a chronic-recidive inflammatory skin disorder with predilection in areas rich of sebaceous gland. The most common clinical manifestations are pruritus and scales. Although SD can be diagnosed without special tools, other examinations may be needed to determine additional specific therapy. Trichoscopy is one of the noninvasive tools which can help to diagnose SD as it can provide the microstructure view of the scalp. Materials and Methods: This descriptive study was conducted to explore the trichoscopic features of SD and its characteristics. There were 96 SD patients enrolled in this study. The scalp was divided into four areas, and each area was scored based on Seborrheic Area Severity Index, comprising erythema, desquamation, number of papules, and percentage of lesion area. The most severe area was examined with a trichoscopy to observe the characteristics of hair and scalp. The association between trichoscopic findings and SD severity was analyzed with Fisher's exact test. Results: Overall, the participants were 36% males and 64% females with the mean age of 30 (13–70) years old. Based on the trichoscopic examination, the most common findings were thick hair shafts (72%), white scales (69%), arborizing thin vessels (38%), yellowish area (36%), and structureless red area (19%). These findings were not significantly different between mild and moderate SD ( P > 0.05). Conclusion: Considering the merits and demerits of trichoscopic examination, it can be helpful to aid the diagnosis of SD. Further studies in Asian population with greater sample size are needed to demonstrate more significant result.
