Median raphe canal is an uncommon disease and represents a defect abnormality of the male genitalia. It occurs along the ventral median raphe from the glans penis to the anus. Histologically the canal is lined by stratified squamous epithelium which dose not communicate with the urethra. Surgical excision is the treatment of choice. Recently we observed a 25-year-old male patient who had had a median raphe canal located in the ventral aspect of penis.

BACKGROUND: Woods are capable of causing allergic or irritant contact dermatitis which typically occurs on exposed areas. Because Bolivian rosewood exclusively contains the strong sensitizer R-3,4-dimethoxydalbergione, an increasing number of cases of irritant and allergic contact dermatitis has been reported. CASE REPORT: A 49-year-old, male, wood worker, who handled a variety of woods, developed allergic contact dermatitis. A patch test confirmed a positive reaction to one of the exotic woods, Bolivian rosewood. Allergens found in Bolivian rosewood caused this patient's dermatitis, which cleared when he avoided this wood. CONCLUSION: Exotic woods such as Bolivian rosewood can induce occupational contact dermatitis. Measures to lower the incidence of work-related dermatitis are needed in the workplace. Especially, when cutting or sanding woods, workers should wear proper personal protection.

BACKGROUND: The 2004 World Health Organization classification introduced atypical pituitary adenoma (aPA), which was equivocally defined as invasion with increased mitotic activity that had a Ki-67 labeling index (LI) greater than 3%, and extensive p53 immunoreactivity. However, aPAs that exhibit all of these features are rare and the predictive value for recurrence in pituitary adenomas (PAs) remains uncertain. Thus, we sought to characterize pathological features of PAs that correlated with recurrence. METHODS: One hundred and sixty-seven cases of surgically resected PA or aPA were retrieved from 2011 to 2013 in Seoul St. Mary’s Hospital. Among them, 28 cases were confirmed to be recurrent, based on pathologic or radiologic examination. The pathologic characteristics including mitosis, invasion, Ki-67 LI and p53 immunoreactivity were analyzed in relation to recurrence. RESULTS: Analysis of the pathologic features indicated that only Ki-67 LI over 3% was significantly associated with tumor recurrence (p = .02). The cases with at least one pathologic feature showed significantly higher recurrence rates (p < .01). Analysis indicated that cases with two pathologic features, Ki-67 LI over 3% and extensive p53 immunoreactivity 20% or more, were significantly associated with tumor recurrence (p < .01). CONCLUSIONS: Based on these results, PA tumor recurrence can be predicted by using mitosis, invasion, Ki-67 LI (3%), or extensive p53 immunoreactivity (≥ 20%). Assessment of these features is recommended for PA diagnosis for more accurate prediction of recurrence.

PURPOSE: Patients with chronic gastrointestinal disease are at risk for trace element deficiency due to impaired absorption and gastrointestinal loss. The aim of this study was to evaluate the trace element status of patients with gastrointestinal disease by blood and hair analysis, and to determine the usefulness of hair mineral analysis for diagnosing trace element deficiency not detected by a blood test. METHODS: An analysis of hair minerals was performed and compared with blood mineral analysis in 13 patients with chronic gastrointestinal disease. The concentration of each element in the hair and blood was compared in the subgroups based on parenteral nutritional support or clinical symptoms. RESULTS: Almost all patients had trace element deficiency. The trace elements deficient in the blood or hair analysis included zinc, selenium and copper. The hair zinc concentration was significantly lower in the group receiving parenteral nutritional support. The hair selenium concentration was statistically associated with the clinical symptoms of hair loss, brittle hair and loss of hair pigmentation. CONCLUSION: The results of this study suggest that patients with chronic gastrointestinal disease should receive adequate zinc and selenium replacement to avoid trace element deficiency especially when treated with long-term parenteral nutrition. Hair mineral analysis is useful as a complementary tool for the detection of a trace element deficiency.

Nocardiosis is an acute, subacute, or chronic infection, most often beginning in the lung, and usually affects the immunocompromised host. Nocardial infections are not rare in the United States, 500 to 1000 cases are recognized each year, but rarely reported in Korea. Disorders associated with cellular immune dysfunction are the major risk factors for nocardiosis. We report one case of brain and retroperitoneal abscess caused by Nocardia asteroides in patient who has had a chronic lymphocytic leukemia and diabetes mellitus, with a review of the relevant literature.

OBJECTIVES: Incresed gamma-glutamyltransferase (GGT) concentration has mainly been used as a biologic marker of alcohol drinking and liver diseases. However, some recent reports have suggested that serum GGT concentration may be an early biomarker of oxidative stress and associated with chronic diseases like hypertension, DM, hyperlipidemia, CHD, stroke etc. In this study, we analysed the factors associated with increased serum GGT level and evaluated the clinical application of serum GGT in predicting the risk of chronic diseases. METHODS: The data were collected from 15,546 periodic health examinations, 9,660 males and 5,886 females, done at one university hospital from 2001 to 2003. We analysed self-questionnaire, physical examination and laboratory data. Statistical analyses(t-test, ANOVA, Pearson's correlation analysis, multiple regression analysis and logistic regression analysis) were done by SPSS for windows 10.0. RESULTS: Mean serum GGT levels were quite different according to age, sex, BMI, smoking and alcohol drinking (all P-value < 0.001), but were not different by regular vitamin intake or not (P-value=0.117). There was significant correlation between serum GGT level and the variables (of age, BMI, blood pressure, Hb, fasting blood sugar, total cholesterol, AST and ALT) (all P-value < 0.001). In sex-specific multiple regression analysis, increased serum GGT level was significantly associated with age, alcohol drinking, smoking, blood pressure, fasting blood sugar and ALT in males (all P-value < 0.001), and with age, alcohol drinking, smoking, Hb, blood pressure, total cholesterol and ALT in females (all P-value < 0.05). In sex-specific logistic regression analysis, increased serum GGT level was significantly associated with risk of 'clinical abnormalities'. This risk increased about 13-fold in males and 4.6-fold in females for serum GGT level over the third quatile, compared with under the first quartile. CONCLUSIONS: Serum GGT level is increased not only by alcohol drinking or liver diseases, but also by many other factors associated with chronic diseases and behavioral factors. Thus many factors should be considered in evaluating an increase in GGT level, even when within the upper normal range. Serum GGT level may be a predictor for the early development of chronic diseases.

Among various dermatological entities, toxic epidermal necrolysis (TEN) is a rare but potentially fatal delayed hypersensitivity reaction to numerous medications. A 38-year-old male presented with systemic hypersensitivity reaction, such as high fever, pain in the eyes, and diffuse pruritic erythematous maculopapular eruptions with multiple targetoid plaques that became vesicular and bullous. Oral mucosa and conjunctivae were involved. The first sign appeared about 1 week after taking methazolamide (50 mg twice a day) for the management of glaucomatous eyes. Although methazolamide was discontinued, blistering and skin denudation progressed to affect up to 80% of the body surface area and a positive Nikolsky sign was noted. High fever also persisted. Skin lesions started to improve after 2 weeks of management and fever subsided. Cutaneous lesions improved with minimal permanent sequele 2 months later. HLA-B*5901 was found by high-resolution genotyping. The lymphocyte activation test performed 6 months after remission showed a positive response to methazolamide challenge. This is the first case of methazolamide-induced TEN in which methazolamide was confirmed as a culprit drug by the lymphocyte activation test.

Although many hepatitis B virus (HBV) mutants have been found in all open reading frames since the precore defective mutant was initially reported, systematic investigations of diverse HBV mutant populations in hepatitis B patients have not been performed. Therefore, we examined whether heterogeneous mutant populations simultaneously exist in Korean hepatitis B patients. In order to detect hepatitis B virus mutants, we amplified a conserved core region and a surface antigen region of HBV DNA by PCR from sera of 27 Korean chronic hepatitis B patients, and then performed single strand conformational polymorphism analysis followed by DNA sequencing analysis. The results showed that heterogeneous HBV mutants in both regions were present in a single as well as in various hepatitis B patients. Sequence analysis revealed a defective interfering particle with missense mutation in the core region. We also found that two subtypes of adr and adw coexisted in a single patient. In addition, a point mutation causing a stop codon in the surface antigen region was observed. We are further analyzing the clinical implications of HBV mutants to identify their roles in the pathogenesis of chronic hepatic disorders induced by HBV.
