Kerion celsi is an inflammatory infection, caused by a vigorous T-cell mediated host response to the dermatophyte infection. In the case of severe inflammation, it can be misdiagnosed as other disease like cellulitis, impetigo, furuncle and epidermal cyst. Microsporum(M.) canis is most likely transmitted by contact of animal hosts such as cats and dogs with humans. We report the 75-year-old female who presented two months history of tender erythematous scaly plaques with pustules, crusts on right scalp area. At first, from the histopathologic findings of the lesion, the patient was diagnosed epidermal cyst because of cyst-like structure in mid-dermis. But the fungal culture revealed M. canis as the causative fungus. Herein we report a educational case of kerion celsi mistaken for ruptured epidermal cyst.

BACKGROUND: Staphylococcal scalded skin syndrome (SSSS) is a blistering disease of superficial skin mediated by Staphylococcus aureus (S. aureus) exfoliative toxin. Generally, SSSS affects mainly infants and children younger than 5 years and has a good prognosis. However, an increasing number of cases of methicillin-resistant S. aureus (MRSA) have been reported recently. OBJECTIVE: The purposes of this study were to evaluate the clinical features and course, to investigate the microbiological manifestations, and to perform antimicrobial susceptibility testing of SSSS among Korean children. METHODS: From March 2003 to July 2016, a total of 141 children were included in this study. The patients were divided into two different groups according to time of onset of their disease: before or after September 2011. We retrospectively reviewed medical records, microbiological results, bacterial detection sites, and antimicrobial susceptibility tests of all participating children. The results of comparison between the two groups were evaluated using the chi-square test. RESULTS: S. aureus infections were identified in all patients. Among all cultured S. aureus specimens, 63.1% (89/141) showed methicillin resistance. Beginning in September 2011, MRSA infection showed a significantly higher prevalence than that previously demonstrated (71.7% vs. 38.8%; p=0.0010). Moreover, MRSA infections were detected on the skin and neck and in the nose (each detected on 61, 41, and 18 occasions, respectively) with overlap observed in many cases. CONCLUSION: In conclusion, since the prevalence of MRSA infection has been gradually increasing in recent years, careful consideration is needed in the selection of antibiotics covering MRSA.

Subcorneal pustular dermatosis is a pustular eruption that shows subcorneal pustules containing polymorphonuclear leukocytes and chronic progression. It most commonly affects the trunk, inguinal region, and axilla of middle-aged women, and the pustules are distributed bilaterally. Cultures of the pustules consistently do not reveal bacterial growth. Subcorneal pustular dermatosis rarely happens, and no specific etiology and pathogenesis are known. Thus, we present this case to provide dermatologists with information on its adequate diagnosis and treatment and to inform them of the risk of subcorneal pustular dermatosis in kidney dialysis patients who use darbepoetin-α.

OBJECTIVES: We developed a Korean version of the Brief Measure of Worry Severity(BMWS), and examined its reliability, validity, and factor structures. We also explored the associations of pathological worry with depression and anxiety. METHODS: Three hundreds fifty-two subjects including community population and college students completed the BMWS, and 27 subjects repeated the scale three weeks later. Reliability was assessed by Cronbach's coefficient alpha and test-retest correlation. The external validity was examined by the correlation of the BMWS score with the scores of Beck Depression Inventory(BDI), Patient Health questionnaire-2(PHQ-2), State Anxiety Inventory(SAI), and Trait Anxiety Inventory(TAI). And principal component analysis was performed to evaluate the construct validity. The associations of pathological worry with depression and anxiety were explored using partial correlation analysis. RESULTS: Cronbach's coefficient alpha for the BMWS was 0.904 and test-retest correlation was 0.56(P<0.01). The Spearman correlation coefficients of the BMWS score with the scores of BDI, PHQ-2, SAI, and TAI were 0.60(P<0.01), 0.42(P<0.01), 0.36(P<0.01), and 0.59(P<0.01), respectively. The BMWS showed unifactorial construct. When controlling for TAI score, the correlation coefficient between the BMWS score and the BDI score was 0.357(P<0.01), and when controlling for BDI score the correlation coefficient between the BMWS score and the TAI score was 0.446(P<0.01). CONCLUSION: The Korean version of the BMWS was found to be a reliable and valid questionnaire for measuring pathological worry. And we could identify the associations of the pathological worry with depression as well as anxiety.

Background: Acanthosis nigricans is characterized by a velvety thickening of the epidermis accompanied by different degrees of hyperpigmentation, and known to be linked to obesity and insulin resistance. Objective: We aimed to analyze obesity-related factors in acanthosis nigricans patients and to evaluate the correlations between acanthosis nigricans and various factors. Methods: From January 2004 to February 2015, 27 acanthosis nigricans patients participated in this study. Blood samples were collected from a control group of seven overweight people and from the seven acanthosis nigricans patients, and they were analyzed for different obesity-related factors. Skin samples were collected from the 23 acanthosis nigricans patients and from 11 patients with epidermal nevi, and immunohistochemistry was performed to detect the presence of adiponectin receptor 1, adiponectin receptor 2, and the leptin receptor. Results: The median serum leptin level in the acanthosis nigricans patients (13 ng/mL) was significantly higher than that in the overweight control individuals (8.9 ng/mL) (p=0.021). The acanthosis nigricans patients had significantly higher levels of insulin-like growth factor-1 in their serum samples (p=0.017). The immunohistochemical analysis determined that the skin from the acanthosis nigricans patients stained significantly more intensely for the leptin receptor compared with that seen in the skin from the patients with epidermal nevi (p=0.002). Conclusion In conclusion, this study’s findings suggest that the levels of leptin and insulin-like growth factor-1 in the serum, and the expression of the leptin receptor in the skin are elevated with acanthosis nigricans.

Retrograde jejunogastric intussusception defined as a segmental invagination of jejunal loop into stomach through stoma is a rare complication following partial gastric resection. Endoscopy and UGI series is very helpful in the diagnosis of this disease. Although the management of this disease is usually surgical, an endoscopic reduction can alternatively be attempted. If endoscopic reduction was failed, operation should be immediately per-formed in the acute type because of its high mortality. When anatomical reduction is done on due time, the prognosis is fairly good. We report a case of retrograde jejunogastric intussusception with a brief review of the literature. There was a 56 year old male patient who visited the hospital with chief complaints of severe epigastric pain and vomiting. He had subtotal gastrectomy for gastric carcinoma 6 years ago. On emergency endoscopy the type IIa jejunogastric intussusception was found. As the patient was suspected to be incar-cerated, surgical reduction was performed without delay. He was discharged on the 8th admission day.
