We report a case of a skin problem induced by a visual display t rminal in a 24-year-old female. The patient had erythematcn.is rashes, crusts on both zygomatic areas and upper eyelids with itching, burning and pain sensations after she had been exposed to her visual display terminal. After the cassation of exposure, her skin lesions were markedly improved. A proioction test with her own visual display terminal was positive.

Bullae and sweat gland necrosis have been often described in patients with mental ges, whieh commonly alanifested as erythematous or vesicobullaus lesions on pressure sites. Histopathologically, the aecrosis of sweat glands is a characteristic 6nding. Generalized and/or loca1 tlssue bypoxia due to prolonged ieamobihxation may have resulted in these clinical and histopakological manifestations. To date, we have experielwed 15 cases with bulla and sweat gland necrosis. On admission, about half the patients had carbon monoxide poisoning, and the remainders had alcohol overdosage, drug inioxication, and others. A11 our patients had menfal changes caused by carbon wonoxide poisening, aleohol intoxication, and others. Abrupt erythematous swelling and/or vesicobullous lesione affected pressure sites in all patients. Three patietns had erythematoias lesiqms on non-pressure sites simuhtaneously. Histopathologic examinatians of 12 biopsy specimes showed the necrosis of the epidermis, intra- or sub-epidermal bulla, and/or sweat gland necrosis.

PURPOSE: The aims of this study were to investigate the frequencies and role of hepatitis B virus(HBV) precore and core promotor mutations in children with chronic hepatitis B infection. METHODS: Sera from 31 children with chronic HBV infection were analyzed by direct sequencing of polymerase chain reaction amplification of HBV DNA. RESULTS: Twenty-nine adr type were analyzed. The mutations in HBV precore region were observed in 8(27.6%) of 29 cases. The G->A mutation of nucleotide 1896(A1896; stop codon) were observed in 4 cases(13.8%). The mutations in HBV core promotor region were observed in 27 (93.1%) of 29 cases. The G(1764)->A mutation(A1764) was observed in 14 cases(48.3%), and among these 12 cases combined with a A to T change at nucleotide 1762(T1762). The mutations in HBV precore region were obsereved in 4(21%) of 19 cases of HBeAg positive group and 9(90%) of 10 cases of HBeAg negative group. A1896 mutation was observed in 2 cases in both HBeAg positive and negative group, respectively. The mutations in HBV core promotor region were observed in 18(94.7%) of 19 cases of HBeAg positive group and 9(90%) of 10 cases of HBeAg negative group. T1762 mutation were observed in 6(31.6%) of 19 cases of HBeAg positive group and 6(60%) of 10 cases of HBeAg negative group(P=0.14). A1764 mutation was obsereved in 7 (36.8%) of 19 cases of HBeAg positive group and 7(70%) of 10 cases of HBeAg negative group (P=0.089). A1896 mutation was observed in 2(18.2%) of 11 cases in increased AST/ALT group and 2(11.1%) of 18 cases in normal AST/ALT group. A1764 and T1762 mutations were higher (61.1%) in AST/ALT increased group than those(27.3%) in AST/ALT normal group, but there was no statistical significance(P=0.077). CONCLUSION: Mutations in the precore and core promotor regions can be frequently detected in children with chronic HBV infection. T1762 and A1764 mutations were observed more frequently in HBeAg negative group and in AST/ALT increased group but there was no statistical significance.

Morphometry of nuclei of the benign and malignant prostatic lesions was performed to study the relationship between nuclear size and shape and the prognosis of prostatic adenocarcinoma. Fifty one cases of prostatic adenocarcinoma and 13 cases of benign prostatic hyperplasia were included to evaluate area, perimeter, Dmax, Dmin, and 5 form factors of the nuclei by image analyzer (Zeiss Ibas 2000) using hematoxylin-eosin stained slides. All analytic factors of nuclear size and shape were significantly different between benign lesions and adenocarcinomas. Increased nuclear size was associated with nu- clear irregularity, presence of metastasis, advanced clinical stage, and high Gleason's grade and score of prostatic adenocarcinoma. On Kaplan-Meier method, survival was decreased with older age, no hormonal treatment, stage D, high Gleason's grade and stage as well as with larger size and irregular shape of the nuclei. In conclusion, morphometry of nuclei of the prostate can be a helpful tool to differentiate between benign and malignant lesions. Nuclear morphology is thought to be associated with prognosis of prostatic adenocarcinoma.

We report a case of xanthoma disseminatum in a 24 year old male paitient. Multiple yellow-brown papules developed on the flexor aurfaces, such as the neck, axillae, antecubital fossae, groin, and perianal regions. Some papules were detected arouns the eyes and uvulai. biopsy specimen revealed a dense infiltrate of histiocytes, foam cells, Touton giant cells, and other inflammatory cells. No Langerhans granules were seen in the electron microscopic analysis.

Chronic kidney disease (CKD) is a major public health problem. It is estimated that 400-600 million adults worldwide have CKD. Furthermore, more than 5% of the adult population has some form of kidney damage. CKD is not an isolated disease, but is strongly linked to other health problems, such as diabetes and cardiovascular diseases (CVD), with high blood pressure as the main indicating risk factor. For example, every year millions die prematurely of CKD-linked CVD alone. However, adverse outcomes of CKD can be prevented through early detection and treatment. Earlier stages of the disease can be detected through routine laboratory measurements. Therefore, a clinical action plan should be developed for each patient, based on the stage of disease. The basic principle of treatment for CKD is to prevent the further deterioration of renal function and to minimize complications, including cardiovascular events. For this purpose, treatment should include specific therapy based on the underlying disease; an evaluation of comorbid conditions; a method of slowing the loss of renal function; the prevention and treatment of CVD as well as complications associated with decreased renal function; and replacement treatment for renal function, using dialysis and transplantation, if signs and symptoms of uremia are present.

Under conditions of contemporary medicine, organ transplantation is only possible when organs are donated, meaning that the donated organ works both as a scarce resource and for public good. Therefore, the allocation of donated organs should be processed under full justice and must maximize medical utility as well. For the last 15 years, we have been striving for fair allocation of donated organs, and, due to the development of the medical environment, a few alterations of the procedure are required. Here are some suggestions to improve kidney allocation in Korea.

We present a case of generalized grannuloma annulare with perforating and subcutaneous forms which occurred in a 15-year-old girl. Two years ago, multiple umbilicated, match head to pea sized, erythematous papules were noted on the upper extremities. Then the patient also experienced crusted or ulcerated erythematous papular lesions on the lower legs. Recently, tender, subcutaneous nodules appeared on both soles. The biopsy specimens from the skin lesions of the hand and the sole showed typical findings of granuloma annulare in the dermis and the subcutis, respectively. On the histopathological examination of the calf lesion, palisading granuloma as well as transepidermally eliminating dermal collagenous and necrotic material were seen. The skin lesions were almost completely improved by treatment with dapsone, 100mg a day, for 8 weeks orally.
