Transitional cell carcinoma of the urinary bladder is the most common cancer of the urinary tract and is characterized by frequent recurrence. Like the other malignant tumor, the genetic alterations leading to neoplastic transformation of the urothelium are related with the activation of oncogenes and loss of functional tumor suppressor genes. Cyclin D1 is a putative protooncogene as cell cycle regulator essential for G1 phase progression and is frequently overexpressed in several human tumor. In this study we performed immunohistochemical stainings of cyclin D1 and p53 in both primary and recurrent transitional cell carcinomas of urinary bladder from 56 patients including 20 cases of recurrent tumor, and compared their results with histopathologic features. The results were as follows. Cyclin D1 immunoreactivity was found in 10 of 10 cases (100%) of grade 1, 25 of 41 (61%) cases of grade 2, and 11 of 25 (44%) cases of grade 3 transitional cell carcinomas. p53 immunoreactivity was found in 40% of grade 1, 63% of grade 2, and 87% of grade 3 lesions. Cyclin D1 expression was significantly higher in Ta and T1 lesions than T2 to T4 by pathologic tumor stage. Conversely p53 immunoreactivity was increased in proportion to the T classification. Cyclin D1 was de creased in recurrent transitional cell carcinomas, compared with primary transitional cell carcinomas. However, there was no statistical significance. In conclusion, cyclin D1 immunoreactivity is associated with low histologic grade and low tumor stage. And there is inverse relationship between the cyclin D1 and p53 overexpression.

Livedo reticularis is a mottled bluish discoloration of the skin which occurs in a netlike pattern and is not a diagnosis in itself, but is a nonspecific reaction pattern. It may be classified as idiopathic and secondary livedo reticularis. Decompression sickness can occur during decompression after diving into deep sea water or during a rapiid ascent from sea level, and is one of the many causes of the secondary livedo reticularis. We report a case of livedo reticulris which developed in a patient with decompression sickness. A biopsy from the purpuric patch revealed an unusual histopathologic finding that resembles those of bullae and sweat gland necrosis in drug induced coma.

We encountered a case of Sweet's syndrome associated with myelodysplastic syndrome in a 60-year-old woman. The clinical presentation strongly suggested Sweet's syndrome. A skin biopsy specimen taken from her skin lesion on the leg showed an infiltration of numerous neutrophils in the subcutis instead of the dermis which is the main area of neutrophilic infiltration in Sweet's syndrome. Among infiltrating cells, many neutrophils(8%) showed nuclear segmentation anomalies, that is, hyposegmentation(pseudo-Pelger-Huet anomaly) or hypersegmentation. Peripheral blood neutrophils had similar anomalies. This subcutaneous variant of Sweet's syndrome, Sweet's panniculitis, is rare and nuclear segmentation anomalies of neutrophils are probably a good clue to underlying myelodysplastic syndrome.

We herein report a case of transient acrodermatitis enteropathica in a 3-month-old, breast-fed, full-term infant. The patient was presented with a 2-month history of diarrhea and crusted erythema- tous patches on the periorificial area. Similar lesions were seen in his siblings. His serum zinc level and the zinc level in his mother's breast milk were markedly reduced. Diarrhea and skin lesions disappeared promptly with oral zinc supplementation and did not recur when zinc was discontinued after three weeks. Our case indicates that even full-term infants, who feed excl-usively on mothers milk, run a risk of developing zinc deficiency, if the concentration of zinc in the breast milk is very low.

PURPOSE: The present study was carried out to determine day-to-day differences in cortisol levels and the molar cortisol-to-dehydroepiandrosterone (DHEA) ratio (molar C/D ratio) in working subjects. MATERIALS AND METHODS: The cortisol and DHEA levels were measured from saliva samples collected 30 minutes after awakening for 7 consecutive days in full-time working subjects that worked Monday through Saturday. To determine the day-to-day differences within subjects, the collected data was analyzed using variance (ANOVA) for a randomized complete block design (RCBD). RESULTS: The cortisol levels from samples collected 30 minutes after awakening on workdays were similar to each other, but were significantly different from the cortisol levels on Sunday. The DHEA levels were not significantly different between the days of week. The DHEA levels on Monday and Tuesday were relatively lower than the levels on the other weekdays. The DHEA levels on Thursday and Friday were relatively higher than the other days. The molar C/D ratios on Sunday were significantly lower than those on workdays. The molar C/D ratios on Monday and Tuesday were significantly higher than those on Wednesday or other workdays. CONCLUSION: The cortisol levels and the molar C/D ratios demonstrate differences in adrenocortical activities between workdays and non-workdays, but the molar C/D ratio additionally represents differences in adrenocortical status between the first two workdays and other workdays. Thus, it is possible that the day-to-day differences in the cortisol levels and the molar C/D ratio represent the adrenal response to upcoming work-related stress.

A clinical observation was made on 19 cages of nonvisualizing tuberculous kidney, who were admitted to national medical center during the period from January, 1981 to April, 1982. Following results were obtained. 1. Most common age group were from 3rd to 5th decade. 2. Most frequent symptom or complaint was grose hematuria and this was subsided after operation. 3. In laboratory findings, pyuria 178.9% and microscopic hematuria (78.9%) were identified. 4. The most common other site of tuberculosis was lung about 12 cases. 5. In microbiologic study for 24hr urine and caseous material from kidney, following answers were given. 1) 24hr urine AFB smear :+: 8cases Tuberculosis culture :+: 4cases 2) Caseous materiel from kidney AFB smear :+: 10 cases Tuberculosis culture :+: 2cases. 6. R.G.P. was tired in all cases, but could not insert the ureteral catheter due to ureteral stricture in 14 cases. 7. All cases of nonvisualizing kidneys were removed.

Tularemia is a zoonosis caused by Francisella tularensis. It is primarily a disease of wild animals. Human infection is incidental and usually results from interaction with biting or blood-sucking insects, wild or domestic animals, or the environment. An increasing number of cases have been reported in several countries. However, in Korea it has not been reported until now. A 40-year old male patient visited our department on Jan 13, 1997, complaining of multiple swollen lymph-nodes on his axillae and reddish swollen left upper arm which contained an abscess at its central portion for about ten days. On Dec 25, 1996, he found a dead wild rabbit on a nearby mountainside, ate it after cooking it by himself with his hands injured. His abscess was drained and microbiologic examination was done. However no microorganism was isolated. His lymph nodes were surgically removed from both axillae, and we investigated them microbiologically and pathologically. On microbiologic examination, small aerobic gram negative coccobacilli were grown on a chocolate agar plate in an aerobic condition with 5% CO2 at 37 degrees centigrade. On H & E staining, the lymph node showed chronic granulomatous inflammation. We sent the microorganism and lymph nodes to the Centers for Disease Control and Prevention in the United States of America for the definitive diagnosis. Finally the microorganism was identified as F. tularensis by culture morphology, biological tests and immunohistochemical staining. We report the first case of F. tularensis in Korea.
