Purpose: The favorable clinical efficacies of intramuscular injection of autologous blood in patients with atopic dermatitis (AD) and intramuscular injection of autologous serum in patients with chronic urticaria have been demonstrated by randomized clinical trials. In this study, we assessed the clinical effectiveness and safety of the intramuscular injection of autologous serum in patients with AD. Materials and Methods: In this randomized, placebo-controlled, and double-blind trial, 23 adolescent and adult patients with moderate-to-severe AD were enrolled. The patients were randomized to receive eight intramuscular injections of 5 mL of autologous serum (n=11) or saline (n=12) over 4 weeks, and were followed up until week 8. Changes in the clinical severity scores of AD assessed by SCORing Atopic Dermatitis (SCORAD), patient-reported Dermatology Life Quality Index (DLQI) score, and incidence of adverse events were assessed from baseline to week 8. Results: One patient in the treatment group and two patients in the placebo group were lost to follow-up before week 8. The intramuscular administration of autologous serum, compared with saline, decreased the SCORAD clinical severity score (-14.8% vs. 10.7%, p=0.006) and improved the DLQI score (-32.6% vs. 19.5%, p=0.01) from baseline to week 8. Serious adverse events were not observed. Conclusion Intramuscular injection of autologous serum may be effective in treating AD. Further studies are needed to evaluate the clinical usefulness of this intervention for AD (KCT0001969).

Syringoma is the most common type of benign intraepidermal eccrine sweat gland tumor in Korea, and is usually found in women in their forties. It presents mostly as a localized lesion, preferring the lower eyelid, cheek, or forehead, and rarely invades the vulval area, and in the case of children, vulvar invasion is even more rare. Tranilast is an antihistamine used for atopic dermatitis and asthma, and has recently been used for the treatment of keloid. A few previous studies have reported both localized and generalized forms of syringoma being effectively resolved with tranilast. Herein, we report a rare and interesting case of milium-like syringoma, which manifested on the vulval area of 10-year old girl that was successfully treated with tranilast.

PURPOSE: The triglyceride-to-high-density lipoprotein cholesterol (TG/HDL-C) ratio has recently been reported as a biomarker of cardiometabolic risk in obese children and adolescents. The purpose of this study is to describe the TG/HDL-C ratio and related factors in overweight and normal weight Korean children and to evaluate whether the high TG/HDL-C ratio is associated with insulin resistance in overweight children and adolescents. METHODS: Data from 255 overweight (aged 8.7±2.0 years) and 514 normal weight (aged 8.9±1.8 years) children and adolescents were evaluated. Glucose, insulin, total cholesterol (TC), HDL-C and TG levels were measured after overnight fasting, and the TG/HDL-C ratio, non–HDL-C and the homeostasis model assessment of insulin resistance (HOMA-IR) were calculated. RESULTS: The TG/HDL-C ratio was higher in overweight group compared to normal weight group (P < 0.001). Among overweight children and adolescents, alanine aminotransferase (P=0.018), non–HDL-C (P < 0.001), and HOMA-IR (P=0.004) were different between the TG/HDL-C ratio tertile groups. The prevalence of elevated HOMA-IR was increased with increasing TG/HDL-C ratio tertiles (P for trend=0.003). On regression analysis adjusted for age and sex, the BMI (β=0.402, P=0.001) and TG/HDL-C ratio (β=0.251, P=0.014) were independently associated with HOMA-IR (adjusted R2=0.324). The TG/HDL-C ratio of 2.0 or more showed higher sensitivity (55.6%) and specificity (72.9%), when compared to TC (≥200 mg/dL), non–HDL-C (≥145 mg/dL), and LDL-C (≥130 mg/dL) for identifying overweight children with elevated HOMA-IR. CONCLUSION: The TG/HDL-C ratio is independently associated with insulin resistance in overweight children and adolescents, and it can be useful in identifying those at higher cardiometabolic risk.

Neonatal hypocalcemia and congenital heart defects has been known as the first clinical manifestation of the chromosome 22q11.2 deletion syndrome (22q11DS). However, because of its wide clinical spectrum, diagnosis of 22q11DS can be delayed in children without classic symptoms. We report the case of a girl with the history of imperforate anus but without neonatal hypocalcemia or major cardiac anomaly, who was diagnosed for 22q11DS at the age of 11 after the onset of overt hypocalcemia. She was born uneventfully from phenotypically normal Korean parents. Imperforate anus and partial cleft palate were found at birth, which were surgically repaired thereafter. There was no history of neonatal hypocalcemia, and karyotyping by GTG banding was normal. At the age of 11, hypocalcemia (serum calcium, 5.0 mg/dL) and decreased parathyroid hormone level (10.8 pg/mL) was noted when she visited our Emergency Department for fever and vomiting. The 22q11DS was suspected because of her mild mental retardation and velopharyngeal insufficiency, and a microdeletion on chromosome 22q11.2 was confirmed by fluorescence in situ hybridization. The 22q11DS should be considered in the differential diagnosis of hypocalcemia at any age because of its wide clinical spectrum.

A 4-month-old infant presented with asymptomatic soft nodules on his right forearm, which had developed since birth. On the suspicion of nevus lipomatosus superficialis (NLS), biopsy was performed. Histopathologic findings showed monomorphic polygonal cells with abundant granular cytoplasm. Immunohistochemical stains for CD68 and vimentin were strongly positive, but were negative for S-100 protein. Based on the pathologic findings, the patient was diagnosed as non-neural granular cell tumor (NN-GCT). GCT can be divided into conventional and non-neural GCT by immunoreactivity for S-100 protein. NN-GCT is typically manifested as a well-circumscribed, papulo-nodular dermal mass, and is known to occur in a younger group than does in conventional GCT, but is rare among children. To our knowledge, there have been no case reports of NN-GCT which appeared at birth and presented as grouped nodules. Therefore, we report this interesting case of congenital NN-GCT clinically mimicking NLS.

BACKGROUND: Usually, we did the fungus culture by collecting nail samples using a surgical blade, but this procedure showed low positive culture rate. An emery board is a tool used to gently grind down and shape the edges of nails. OBJECTIVE: The aim of this study is to compare positive culture rates of nail sampling techniques in diagnosis of onychomycosis using surgical blade and emery board. METHODS: We collected and assessed data of 49 patients in total, with chief complaints of nail problem, and showed positive results in KOH smear. Fungus culture was performed twice in each patient, both by scraping nail with surgical blades and grinding nail piece with emery board. After 4 weeks from culture, we compared positive culture rates of two nail sampling techniques. RESULTS: In 49 patients, 16 patients were male and the other 33 were female, with average age of 51.4 years. When classified by morphological type, there were 45 cases of distal lateral subungual onychomycosis (DLSO) and 4 cases of white superficial onychomycosis (WSO). Culture using emery board produced 18 positive results (36.7%) out of 49 patients, and that using surgical blade produced 9 positive results (18.4%); the difference were statistically significant. In other words, nail sampling using emery board rather than surgical blade resulted in higher positive culture rate. CONCLUSION: Therefore, emery board can be used as a useful device for diagnosis and identification of causative fungi in onychomycosis in clinical practice and a method to enhance positive rates of cultures.

PURPOSE: The clinical usefulness of subcutaneous allergen immunotherapy (SCIT) in the treatment of atopic dermatitis (AD) is still controversial. We analyzed the clinical efficacy of SCIT in patients with AD and the clinical characteristics of patients showing a favorable clinical response to the treatment. MATERIALS AND METHODS: Two hundred and fifty one patients with AD sensitized to house dust mite (HDM) were treated by SCIT using HDM extract. The clinical severity of AD was measured using the standardized clinical severity scoring system for AD (SCORAD) at baseline and 12 months. A favorable clinical response to SCIT was defined as a decrease in SCORAD value at 12 months greater than 50% compared to baseline value. Severe AD was defined as a baseline SCORAD value above 50. RESULTS: A favorable clinical response to SCIT was observed in 73.6% of patients. The proportion of patients showing a favorable clinical response to SCIT was significantly higher in patients with severe AD (90.6%) than patients with mild to moderated AD (63.7%) (p<0.001). Patients with severe AD showing a favorable clinical response had a significantly shorter duration of AD (12.3±8.5 years; mean±SD) than patients with severe AD showing no significant clinical response (20.6±10.9 years) (p<0.05) at baseline. CONCLUSION: SCIT could be a clinically useful therapeutic option for patients with severe AD sensitized to HDM. Early initiation of SCIT might provide a favorable clinical outcome in patients with severe AD sensitized to HDM.

PURPOSE: We studied the changes in subtypes of diabetes mellitus (DM) in children and evaluated the characteristics of each group over the past 20 years. In addition, we also examined the correlation between the glycated hemoglobin (HbA1c) values at the time of diagnosis and lipid profiles. METHODS: The patients were divided into 2 groups: there were a total of 190 patients under 20 years of age firstly diagnosed with DM in Ajou University Hospital. The patients in groups I and II were diagnosed from September 1995 to December 2004 and from January 2005 to April 2014, respectively. RESULTS: The characteristics were compared between the 2 groups of patients. The result showed an increase in percentage of type 2 diabetes and maturity onset diabetes of the young (MODY) patients between the 2 groups. HbA1c and total cholesterol level had statistical significances to explain increasing the low-density lipoprotein cholesterol level among age, HbA1c, total cholesterol level, and z-scores of weight and body mass index (BMI) in type 2 diabetes. R-square was 0.074. However, z-score of BMI and total cholesterol level, not HbA1c, had statistical significances in type 1 diabetic patients. R-square was 0.323. CONCLUSION: The increase in the proportions of both type 2 diabetes and MODY in the last 10 years needed to be reminded when diagnosing the subtypes of DM, and the dyslipidemia should be attended more as a common problem of pediatric diabetic patients.
