A 43-year-old male patient showed well defined, irregular, dark eythematous, thick plaque and tumor with ulceration on the right chest, right axilla, pubis and scrotum, Histopathological findings rervealed atypical lymphocytes showing epidermotrophism and heavy infiltrations in the deep dermis and subcutaneous tissue. The infiltrative cells were positively stained with leukocyte common antigen and T-cell UCHL-1 antigen, but not with L26 antigen. This clinicohisto-pathological features were consstent with dermblade type of mycosis fungoides. The authors report clinicopathological findings of the case with its thrapeutic responses to systemic chemotherapy and radiation treatment.

BACKGROUND: Although the culture of urethral discharge using a cutton swab is regarded as one of the most sensitive and reliable diagnostic methods of gonorrhea, it may give pain or diagnostic methods of gonorrhea, it may give pain or discomfort to patients, and its detection rate may be influenced by the examiner's technical ability. OBJECTIVE: The purpose of this study was to compare the positive culture rates between ure4thral discharge and urinary sediment for the diagnosing of Neisseria gonorrheae. METHODS: We compared this technique with the culture of urethral discharge using the specimens from 357 male patients with gonococcal infection at VD clinic of Jungku Pvblic Health center in Seoul from Jan 1991 to Jun 1993. RESULTS: The culture of urinary sediment was positive in 339 of 357(94.95), whereas the culture of urethral discharge was positive in 346 of 357(96.95). However, these data have no statistical significance(P<0.05). The obe observed sensitivity and specificity of culture of urinary sediment comjpared to culture of urethral discharge were 97.75 and 90.9%, respectively. The predictive value of positive and negative test compared to the culture of urethral discharge were 99.7% and 55.65, respectively. As our data showed low negative predictive value, a negative culture result of urinary sediment does not always imply a negative culture result of urethral discharge. CONCLUSION: Therefore, at present, the previous method of the culture of urethral discharge is more highly recommended and further studies for this diagnostic and/or new method of gonorrhea based on larger group of patients is encouraged.

The clear cell variant of ependymoma is a rare, recently described, intracranial tumor which is composed of clear neoplastic ependymal cells. Clear cell ependymomas may share characteristic histologic features of oligodendrogliomas or central neurocytomas; striking nuclear uniformity, perinuclear halos, and numerous angulated capillaries. In contrast to oligodendrogliomas, however, clear cell ependymomas are noninfiltrating tumors with sharp boundaries. Perivascular pseudorosette formation is frequent. Oligodendrogliomas are usually nonreactive for GFAP compared to diffuse immunoreactivity of clear cell ependymoma. Central neurocytomas may also be differentiated by their immunoreactivity for synaptophysin. This is a case of clear cell ependymoma in a 40-year-old man. By computed tomography and magnetic resonance imaging scans, a well circumscribed cystic tumor with mural nodule was demonstrated in the right frontal lobe. It was 6cm in diameter and well enhanced. Histologically, it was sharply demarcated from the brain parenchyma. The cystic wall was lined by atypical ependymal cells, which "transformed" to clear cells in the solid area. The cells had uniform nuclei and perinuclear halos. Mitotic figures and necrotic foci were focally present. The cells were immunoreactive for glial fibrillary acidic protein (GFAP), while synaptophysin was negative. Electron microscopy revealed densely packed polyheadral cells with scant organelles and well developed intercellular junctions.

Fifty-six patients with tinea versicolor were studied clinically and therapeutically, from July 1984 to August 1985, at the Department of Dermatology, Hanyang University. L atients were treated with 20g sodium thiosulfate solution, 1g isoconazole nitrate cream, lg bifonazole cream and. oral ketoconazole. The result obtained were as follows: 1. The average age of all patients at visit was RO. 1 years, the oldest patient was 72 year-old and the youngest patient was 13 year-old. The male to female ratio was 3. 7: 1. 2. Distribution of lesions were anterior chest(26.8%), back(23.9%), abdomen (19%), axilla (17%), neck(6. 3%), pubic area(4. 2%), upper extremities(1. 4%), hip(0.7%) and lower extremities(0.7%). The incidence of hyperpigmented lesions was 76. 8%, and that of hypopigmented lesions was 23. 2g. 3. Average of treatment duration in each trial group indicated 3. 71-I--0 83 weeks (M+SD) in 20g sodium thiosulfate regimen group, 3. 07+ 0. 73 weeks in 1g isoconazole nitrate, 3.29+1.14 weeks in bifonazole, R. 00+0. 68 weeks in oral ketoconazole. No treatment results show statistically significant differences among the trial groups.

The subject were 653 male patients with uncomplicated gonorrhea at the VD Clinic of Choong Ku Public Health Center in Seoul from January to November 1985. 653 male patients with uncomplicated gonococcal infection were treated one of the following regimens. Five treatment regimens used were 2, 0 gm spectinomycin single 1M, 4 0 mega unit fortified procain penicillin G+2. 0 gm kanamycin sulfate IM preceded by 1 pgm probenecid PO, 6.0 mega unit fortified procain penicillin G+2 pgm kanamycin sulfate IM preceded by 1. 0 gm probenecid PO, 5, 0 rnega unit aqueous crystaline penicillin+2. 0 gm kanamycin sulfate irn preceded by 1, 0 gm probenecid PO and 9 tablets of cotrimoxazole+ 2. 0 gm kanamycin sulfate IM. There were no significant differences in the incidence of PGU among the five treatment groups. The overall PGU rate was 67.3% 59.2% and 53.6% at 3~5, 7~10 and 14 days after treatment respectively. The incidence of PGU at 7-10 days was not significantly higher than that of at 14 days after treatment. It is suggested that it is best to test PGU at 7 days after treatment. Because the longer one waits, the harder to follow the patients, and in earlier period, post-inflammatory irritation might be too frequent. It is also suggested that at 3 5 days after treatment examination of urethritis might serve to compare the effect of treatment regimens on the incidence of PGU.

Genotoxic agents can induce various DNA lesions. DNA-Protein Crosslinks(DPCs) were known as the important DNA lesions which could impair gene expression because DPCs had a high probability of resisting repair and persisting through cell cycle. This repair resistance of DPCs could have biological significance but had not been evaluated clearly yet. Most of the studies that have evaluated the repair of DPCs only compared the extent of DPCs repair with other DNA lesions. We injected K2CrO4, a genotoxic agent, into Sprague-Dawley rats intraperitoneally(5mg/kg) and isolated blood lymphocytes 12 hours later. These lymphocytes were cultured in the mitogen added growth media and mitogen free media separately. The degree of the repair of DPCs was monitored for 4 days by the K-SDS assay. 4 day later, the amount of DPCs decreased by 4.6% in the mitogen added media but in creased by 10.9% in the mitogen free media. These results showed that DPCs induced by K2CrO4 were not repaired easily and the DPCs were biologically significant DNA lesions. We thought the decrease of DPCs in the mitogen added media was not due to the repair of DPCs, but from the increase of normal cell proliferation. Therefore, it is very important to consider the proliferation of normal cells when estimating the repair of DPCs.

Hemolytic disease of newborn due to Rhesus incompatibility occurs mostly by anti-Rh(D) antibodies. But recently, because of Rh(D) immune globuin prophylaxis, Rh(D) incompatibility is decreased and importance of minor group incompatibility is increasing. The majority of minor blood group incompatibilities are anti-c, anti-E or anti-Kell, but hemolytic diseases caused by combination of these antibodies are relatively rare. The 21 day-old male neonate was admitted because of pallor and poor feeding for 2 days. Laboratory data showed severe normochromic and normocytic anemia with increased reticulocyte and bilirubin. Patient's and his mothers blood type was B, Rh(D) positive. Minor blood groups of mother's and sons were different and anti-c and anti-E antibody were detected in mother's serum. After transfusions of two times with anti-c and anti-E free B, Rh(D) positive blood, the baby was discharged at 11th hospital day with good general condition.

It is notoriously difficult to obtain a sound bony union of congenital paeudarthrosis of tbe tibia with conventional methods. This paper is the results of using the free vascularized fibular graft for congenital pseudarthorsis of the tibia in 7 patients since 1978 in this hospital, which is the first attempt in Korea. During the follow-up periods from 9 months to 32 months, 5/7 patients(71%) had good or excellent bony union, 2 patients had bone resorption at tbe distal site of grafted bone and required a second supplementary cancellous bone graft with electrode insertion. So it is thought that the free vascularized fibular graft is one of good methods of treatment for congenital pseudarthrosis of the tibia.

BACKGROUND: Postherpetic neuralgia is usually defined as pain persisting for more than one month after the onset of the eruption of herpes zoster, although there is a overlap between this and the pain of the acute zoster. Many approaches have been proposed to treat postherpetic neuralgia, however, it remains a source of frustration for both patients and physicians. OBJECTIVE: The purpose of this study was to determine more precisely the relationship between the effects of continuous epidural blockade and the time of treatment on postherpetic neuralgia. METHODS: We analyzed the results of 5 patients with postherpetic neuralgia for whom continuous epidural blockade was performed within 1 month after the onset of postherpetic neuralgia, and compared them with the results of 5 patients for whom continuous epidural blockade was performed after 1 month after the onset of postherpetic neuralgia. RESULTS: Continuous epidural blockade performed within 1 month after the onset of postherpetic neuralgia reduced pain significantly, compared to the results of continuous epidural blockade performed after 1 month after the onset of postherpetic neuralgia. CONCLUSION: Continuous epidural blockade performed within 1 month after the onset of postherpetic neuralgia may be the treatment of choice for the pain.
