RESUMO
Background@#Scabies is a parasitic infection caused by the Sarcoptes scabiei var. hominis mite. Its incidence has been increasing in recent years; however, no study has evaluated the clinical aspects of scabies in children and adolescents in Korea. @*Objective@#To evaluate the clinical characteristics and epidemiological features of scabies among children and adolescents and to investigate the clinical efficacy of topical therapies for the treatment of scabies. @*Methods@#We retrospectively reviewed the medical records of 62 patients under 18 years of age with scabies during a 10-year-period. @*Results@#Sixty-two patients with 62 scabies were investigated. These patients showed scabies mites or eggs under microscopic examination or showed clinical improvement after treatment. There were 36 boys (58.1%) and 26 girls (41.9%). The mean age of the boys was 9.3 years and that of the girls was 8.2 years. The most common primary lesions were erythematous papules (93.5%), and the commonest sites of the skin lesions were the hand (64.5%) and the trunk (61.3%). The most common suspected mode of transmission was through contact among families living together. The mean time to complete treatment was 46.1 days using 1% gamma benzene hexachloride lotion, 37.1 days using 10% crotamiton ointment, and 22.8 days using 5% permethrin cream. @*Conclusion@#We confirmed the epidemiological features and clinical characteristics of scabies in children and adolescents, including contact sources and treatment. This study could provide useful data for the prevention and management of scabies in children and adolescents.
RESUMO
Eczema herpeticum is a widespread herpes simplex infection that favors eczema-damaged skin, including skin involved with atopic dermatitis. Here we report a case of a 27-year-old woman who presented with febrile, painful, punched-out, erosive, macular eruptions and crusts on her face, upper trunk, and antecubital fossae. Polymerase chain reaction analyses of the blood and skin lesions were positive for type 1 herpes simplex virus, and blood cultures established on admission showed methicillin-sensitive Staphylococcus aureus. She was diagnosed with bacteremia superimposed on eczema herpeticum. True bacteremia rather than contaminated blood cultures was suspected because her fever did not improve after 2 days despite the administration of antivirals. Repeated scratches to the lesional skin most likely aggravated the epidermal barrier damage, enabling the penetration of the dermal vessels by colonized S. aureus.

RESUMO
BACKGROUND: The involvement of oxidative stress in the pathogenesis of various skin diseases has been suggested. OBJECTIVE: Urinary malondialdehyde (MDA) and 8-hydroxydeoxyguanosine (8-OHdG) levels served as indices of oxidative stress. We explored whether MDA and 8-OHdG levels were higher in patients with atopic dermatitis (AD) than in healthy controls. In addition, we evaluated the optimal cut-off values for 8-OHdG and MDA in the diagnosis of AD. We explored the associations between AD severity and the levels of serum IgE and oxidative products. METHODS: Urine samples were obtained from 52 AD patients and 27 healthy controls. We measured MDA levels (reflecting lipid oxidation) and 8-OHdG levels (reflecting DNA oxidation). Disease severity was assessed using the Scoring of Atopic Dermatitis (SCORAD) index. RESULTS: The urinary 8-OHdG level was 208.37±145.39 ng/mg Cr in AD patients and 115.65±63.95 ng/mg Cr in healthy controls. The urinary MDA level was 2.92±1.06 mmol/mg Cr in AD patients and 2.20±0.54 mmol/mg Cr in healthy controls. Both the urinary 8-OHdG and MDA levels were significantly higher in AD patients than in healthy controls (p=0.007, p=0.001, respectively). However, we found no correlation between disease severity or serum IgE and oxidative product levels. Levels of oxidative products did not differ significantly between children and adolescents and adults, males and females, or patients with intrinsic or extrinsic AD. CONCLUSION: MDA and 8-OHdG levels were higher in AD patients than in healthy controls. Oxidative stress may be involved in the pathophysiology of the disease.

Colloid degeneration of the skin is a rare, distinct clinicopathological entity characterized by the deposition of colloid material in the dermis. Nodular colloid degeneration (NCD) is a clinical variant of colloid degeneration of the skin. Herein, we report the case of a 40-year-old woman who presented with a 3-year history of multiple asymptomatic yellowish-brown, indurated papules and plaques on her forehead. Histopathologic examination of the lesion revealed deposition of amorphous pale pink homogenous colloid material with irregular clefts, fissures, and scattered pyknotic nuclei in the upper dermis. The material was negative for Congo red staining, and periodic acid-Schiff and Masson's trichrome staining revealed positive reactivity. Scattered fragmented elastic fibers were present in the colloid material on Verhoeff—Van Gieson staining. The patient was diagnosed with NCD. We propose that NCD should be considered in the differential diagnosis of long-standing facial nodules and plaques.

BACKGROUND: The atopic dermatitis (AD) can limit a patient's physical and psychosocial development as well as lower their overall quality of life (QOL), including sleep quality. OBJECTIVE: The purpose of this study was to evaluate the relationships between clinical disease severity, QOL and sleep quality in children and adults with AD. METHODS: The SCORing atopic dermatitis (SCORAD) was examined to evaluate the severity of AD in fifty adult AD patients and 50 children AD patients. A questionnaire based on the children's sleep habits questionnaire (CSHQ) and the children's dermatology life quality index (CDLQI) were used to evaluate QOL and sleep disturbance in children AD patients. The Pittsburgh sleep quality index (PSQI) and dermatology life quality index (DLQI) were used in adult AD patients. RESULTS: The SCORAD and CSHQ score, the SCORAD and CDLQI score and the CSHQ and CDLQI score demonstrated significant correlations. The SCORAD and PSQI score showed no significant correlation. However, there were significant correlations between the SCORAD and DLQI score and the PSQI and DLQI score. CONCLUSION: Increasing severity of AD affects sleep quality in child AD patients. In adults, even though the total score of the sleep questionnaire is not associated with the severity of AD, two components of sleep questionnaire are associated with the severity of AD. There is a significant correlation between sleep quality and QOL in both children and adults. Therefore, we suggest that evaluating the sleep quality as well as clinical severity of the disease is necessary in the management of AD patients.

BACKGROUND: Hair and nails are known to be related in their origin and anatomical structures, and they are similar in their structure and growth pattern. Nail changes were first reported to be associated with alopecia areata (AA) in 1898. One of the clinical features of AA is nail abnormalities, and these are found in 7% to 66% of patients with AA. OBJECTIVE: We evaluated the frequency, clinical presentation, and associated factors of nail changes in patients with AA. METHODS: A prospective study of 121 patients with AA was performed. The diagnosis of AA was made on clinical grounds. Patients' medical history was obtained, and thorough examinations were performed. Patients with other diseases associated with nail changes were all excluded from the study. The association between the clinical features of patients with AA and the prevalence of nail changes was evaluated using logistic regression analysis. RESULTS: Of the 121 patients, 40 (33%) presented with nail changes. In multivariable analysis, younger age (compared with ≥19 years old; odds ratio [OR] 3.663, 95% confidence interval [CI] 1.094~12.346, p=0.035), chronicity (disease duration ≥2 years; OR 2.852, 95% CI 1.230~6.613, p=0.015), and disease subtype (alopecia totalis and alopecia universalis); OR 5.846, 95% CI 1.078~31.717, p=0.041) were identified as independent factors associated with nail changes in patients with AA. Among the nail abnormalities identified, nail pitting was the most common, observed in 20 patients (50%). Trachyonychia was present in 7 patients (16%), leukonychia in 7 (16%), and Beau line in 5 (11%). Other changes were also observed, including melanonychia, onycholysis, absence of lunula, and onychoschizia. CONCLUSION: In conclusion, younger age, chronicity, and disease subtype (alopecia totalis and alopecia universalis) were shown to be independent relevant indicators of the nail changes in patients with AA.
