BACKGROUND: Adrenalectomy does impair the expression of hypothalamic NPY gene in the rat and replacement of glucocorticoid by intracerebroventricular(ICV) route resulted in a normalization of refeeding hyperphagia and weight gain in adrenalectomized(ADX), food-deprived rats. The purpose of this study was to assess the direct effect of CNS glucocorticoid on hypothalamic NPY gene expression which occurs following food deprivation in ADX rats. METHODS: Adult male Wistar rats were fitted with ICV cannulae and restricted the food intake for 14 days. Adrenalectomy and sham operation were done on the 10th day and single ICV corticosterone acetate(100ug/2uL) was given in one ADX group(ADX+CORT, n=9) and vehicle (2uL) was given in another ADX group(ADX+VEH, n=9) and sham rats(SHAM+VEH, n=7). After experiment, we measured NPY mRNA on arcuate nucleus by in situ hybridization. RESULTS: The rate of weight loss of ADX rats closely parallded that of sham-operated rats. Plasma glucose and insulin levels were not significantly different in three groups. Hybridization density on the ARC in ADX+VEH rats(0.42+/-0.02uCi/g: p<0.05) was significantly reduced compared to that in sham controls(0.68+/-0. 11uCi/g). ICV corticosterone injection increased the hybridization density in ADX+CORT rats(0.53+/-0.04uCi/g) compared to vehicle alone, although this did not reach that of controls. NPY gene expression was 40% in ADX+VEH rats and 62% in ADX+CORT rats compared to control rats. CONCLUSIONS: These results are consistent with the hypothesis that CNS glucocorticoid deficiency appears to be responsible for the impairment of refeeding hyperphagia in ADX rats and the effect of CNS glucocorticoid deficiency is a manifestation of impaired activation of hypothalamic NPY gene expression in the ARC.

BACKGROUND: Keratoacanthoma (KA) can be clinically differentiated with ease from other dermatoses. However, the differential diagnosis of KA can sometimes be difficult, and some cases clinically suggest that the results of skin biopsies of lesions thought to be KA indicate other diseases. OBJECTIVE: The purpose of this study is to examine the diagnostic yield in submitting clinically diagnosed KA that showed solitary symmetric, firm, erythematous, or skin-colored nodules. METHODS: We retrospectively reviewed the clinical records of 54 patients with a clinical diagnosis or differential diagnosis of KA who received biopsies and visited the department of dermatology from January 2004 to December 2013. We compared clinical and histopathologic diagnoses and analyzed the rate of concurrence. In addition, clinical features, including age, sex, location, and duration were investigated. RESULTS: Of the patients, 40.7% were clinically diagnosed with KA, but the results of the histopathology tests indicated other diseases. The mean age of the patients with KA was 72.8 years, and the ratio of men to women was 1 : 0.92. Of the new patients, 0.07% had KA, and most of the lesion sites (84.0%) were caused by sun exposure. Other diseases that are more common in patients with KA are squamous cell carcinoma (55.2%), basal cell carcinoma (20.7%), seborrheic keratosis (6.9%), verruca vulgaris (6.9%), pyogenic granuloma (3.4%), clear cell acanthoma (3.4%), and Bowen's disease (3.4%). CONCLUSION: Skin lesions thought to be KA need more examinations, and skin biopsies of appearances of clinically atypical lesions that cannot completely exclude the possibility of precancerous or malignant lesions are strongly recommended.

BACKGROUND: Lip skin diseases are common findings in dermatology. However, most dermatologists are not familiar with the clinical features of lip skin diseases due to the special characteristics of the lip. OBJECTIVE: This study aimed to evaluate the clinical and histopathological features of lip skin diseases. METHODS: We retrospectively reviewed 259 patients who underwent biopsy for labial diseases at the Department of Dermatology from January 2002 to December 2011. We compared the clinical and histopathological diagnoses and analyzed the rate of concurrence and labial tumor distribution. In addition, demographic and clinical features, including age, sex, location, and disease duration, were investigated. RESULTS: The mean age of the patients was 56.8 years and the male-to-female ratio was 1:0.77. Lip skin diseases accounted for 4.1% of all new patients during the study period, with the lower lip being the most commonly affected site (88.4%). The most common disease was actinic cheilitis (35.1%), followed by chronic cheilitis (11.6%), mucocele (10.0%), and squamous cell carcinoma (9.7%). The most common type of tumor was actinic cheilitis (54.8%), followed by mucocele (15.7%), squamous cell carcinoma (15.1%), hemangioma (4.2%), pyogenic granuloma (4.2%), keratoacanthoma (1.8%), and basal cell carcinoma (1.2%). Before the patients came to the university hospital, they received medical treatment at various clinics and departments, including dermatology clinics (55.3%), internal medicine (26.2%) and urology departments (10.7%), and general practitioners (9.7%). CONCLUSION: This study provides novel and useful data on the incidence and characteristics of lip skin diseases. Compared to previous studies, the frequency of lip tumors was relatively high and variable in this study. Based on these results, we advise physicians to, if in doubt, initially diagnose and treat for actinic cheilitis and labial tumors (especially squamous cell carcinoma) caused by long term exposure to the sun.

Tuberculoma means a tumor-like mass resulting from enlargement of a caseous tubercle which microscopically shows infiltration of epithelioid cells, Langhans giant cells and lymphocytes. In a 57-year-old woman suffering from left renal tuberculosis, we incidentally found a large retroperitoneal tuberculoma (site: retrohepatic, above right adrenal gland, below diaphragm and outside Gerota`s fascia, size: 13X11x9cm). Generally, Mycobacteria tuberculosis invade the lung via airway, and subsequently, they can be disseminated to any organ or tissue. They are apt to establish disease in the organ or tissue of high oxygen tension level. We report a case of retroperitoneal tuberculoma with wonder that it could develop in the retroperitoneum of poor blood supply.
