Callus is a nonpenetrating circumscribed hyperkeratosis produced by repeated friction or pressure. It occurs on parts subjected to intermittent pressure, particularly on the palms and soles, and particularly over the bony prominences of the joints. In painful callosities of the feet, ill-fitting shoes and orthopedic problems of the foot (bunions, exostoses) are some of the etiological factors to be considered. Gout is a condition of inborn metabolic and/or acquired form of the disease characterized by hyperuricemia, tophaceous deposits of sodium urate and recurrent attacks of arthritis. We present a case of callus caused by tophi. The patient was a 45-year-old man who had complained of a painful, well-demarcated, hyperkeratotic plaque on the heel of the left foot for 18 months. After the tophi beneath overlying whitish thickened skin had been removed, the skin lesion disappeared and to date has not recurred.

Phosphoinositide-specific phospholipase C(PLC) is known as a key enzyme which produces two major second messengers: diacylglycerol and inositol 1,4,5 trisphosphate. Although it has been suggested that PLC beta isozymes have important roles in nervous system, less is known about the function of PLC beta in development of nervous system. We have localized the mRNA expressions of PLC beta isozymes in the postnatal rat brains by id firm hybridization histochemistry. In the postnatal rat brains, each isozyme of PLC beta showed differential expression pattern. The expression of PLC beta1 mRNA was found in various areas including olfactory bulb, cerebral cortex, caudate putamen, hippocampus, dentate gyrus, and cerebellum. In general, the expression in these areas was gradually increased after birth (PO) until postnatal day 21 (P2l) and slightly decreased to adult level. The expression of PLC beta2 mRNA was not found in postnatal rat brains. The expression of PLC beta3 mRNA was found from P0, peaked at Pl4, and decreased to adult level in the purkinje cells of cerebellum. PLC beta4 mRNA was strongly expressed in the thalamus, cerebellum, cerebral cortex, and olfactory bulb. In these areas, the expression was gradually increased after birth, peaked at P2l, and decreased to adult level. In whole body parasagittal sections of 18 day old rat embryo, PLC betal mRNA was exclusively expressed in nervous tissue, PLC beta3 and PLC beta4 were expressed in various tissues, and the expression of PLC beta2 was not found in any kind of rat tissues. From the different spatiotemporal mRNA expression patterns of PLC beta isozymes in the postnatal rat brains, it is suspected that each PLC beta isozyme may have specific role in signal transduction for postnatal development of rat brain.

Spindle cell hemangioendothelioma was first described in 1986 by Weiss and Enzinger as a low grade angiosarcoma resr mbling a cavernous hemangioma and kaposis sarcoma. Recently, it is suggested to be non neoplastic lesion or reactive process arising from pre-existing vascular mal- formation. We report a case of spindle cell hemangioendothelioma in a 9-month-old boy. He had multiple, variable sized, colorful, cutaneous or subcutaneous nodules on the forearm and hand. The tumor first appeared on the forearm as erythematous patches at birth and grew rapidly with- in 3 months. Histopatholgical findings showed that the lesion was composed of thin walled cavernous spaces mixed with spindle cells and occasional epithelioid endothelial cells containing intracytoplasmic vacuole. Most af the endothelial cells lining the cavernous spaces and intracytoplasmic lumina, were positive for factor VIII associated antigen. But the spindle cells were negative. Atypical vascular structures resembling arteriovenous shunts were noted around the tumor suggesting a reactive proliferation due to disturbance of local blood flow. Several turnors were excised. No recurrence has been recognized in the one year- follow-up period.

Management of the small lower ureteral stone has been attempted by either transurethral manipulation or expectant therapy. To date, however, the choice of proper method has depended mostly on clinician's preference, and the effectiveness of the transurethral stone manipulation has remained controversial. Herein we evaluated the effectiveness of the transurethral stone manipulation, using with the Dormia dislodger, in 37 patients with lower ureteral stone less than 10mm in greatest diameter. The results are summarized as follows. 1. The overall success rate was 68% (25 of 37 patients); Immediate delivery of the stone was observed in 16 of 37 patients. In another 5 patients the stone was removed at the time when the indwelled ureteral catheter was taken out. In the remaining 4 patients the stone passed spontaneously within a week following the procedure. 2. Higher success rate was observed in smaller stone; 79% in less than 4 mm, 58% in 46 mm, and 33% in 610 mm in it's greatest diameter, respectively. 3. The morbidity rate was 8.1% (3 of 37 patients); In one patient a broken basket was retained in the ureter, which was removed at the time of ureterolithotomy. In another patient a ureteral stricture requiring periodic dilation was complicated. And in the other patient persistent hematuria was observed, which was relieved by conservative management. These results suggest that transurethral manipulation might have to be initially applied to unremittingly painful patients with small lower ureteral stone.

BACKGROUND: The bcl-2 is an oncogene involved in tumorigenesis by blocking apoptosis, or programmed cell death and over-expression of bcl-2 protein has been reported in several malignant tumors such as lung cancer, basal cell carcinoma, breast cancer and malignant melanoma. However, there have been only a few studies about bcl-2 expression of cutaneous T cell lymphoma. OBJECTIVE: The purpose of this study was to examine whether there is any difference in expression of bcl-2 between mycosis fungoides(MF), angiocentric T cell lymphoma, angioimmunoblastic T cell lymphoma, subcutaneous T cell lymphoma and anaplastic large cell lymphoma. We also evaluated the statistical significance between expression of bcl-2 and the prognosis of the diseases. METHODS: Routine paraffin sections of formalin-fixed 36 tissues (14 MF, 7 angiocentric T cell lymphoma, 5 subcutaneous panniculitic T cell lymphoma, 2 anaplastic large cell lymphoma, 1 angioimmunoblastic T cell lymphoma, 1 unspecified peripheral T cell lymphoma, 2 small plaque parapsoriasis, 2 psoriasis and 2 lichen planus) were labelled with anti-bcl-2 monoclonal antibody using an avidin- biotin-peroxidase complex. Normal skin for bcl-2 served as negative controls. RESULTS: The results were as follows. l. All cases of benign inflammatory diseases, small plaque parapsoriasis and patch stages of MF showed positive staining for bcl-2. Therefore, there were no differences in expression of bcl-2 among these diseases. 2. In the plaque and tumor stages of mycosis fungoides, statistically significancant differences in bcl-2 expression were not found during disease progression. 3. bcl-2 expression in peripheral T cell lymphoma (five in seven cases of angiocentric T cell lymphoma showed positive staining but all other peripheral T cell lymphoma was negative) decreased significantly (p<0.05) than that of MF. 4. No statistical significance was found between bcl-2 expression and prognosis of cutaneous lymphoma (p>0.05). CONCLUSION: These results suggest that the loss of bcl-2 expression may play a significant role in progression of cutaneous T cell lymphoma except in MF and angiocentric T cell lymphoma.

Ureteroscopic removal of the stone is now popular for the management of the lower ureteral stone. A clinical study was performed on our 75 patients with lower ureteral stone treated with ureteroscopy. Of the 75 stone manipulations 62 (83%) were immediately successful and the final success rate including spontaneous delivery of stone or fragment after the procedure was 87 percents (65 cases). Of 57 smaller calculi than 1 cm (radiographic largest diameter) 50 (88%) were removed successfully. Mean duration of postoperative hospitalization was 5.6 days. There were no interrelations between the success rate and anesthetic methods. Significant complications during or after procedure were not identified. We conclude that ureteroscopic removal of stones under direct vision can be done safely and be the first choice of procedure for the lower ureteral stones.

Trichophyton tonsurans is a major causative agent of tinea capitis in the United States, Canada, Mezico and other Latin American countries, but the infection of T.tonsurans has not been reported in Korea. We report a case of tinea capitis caused by T. tonsurans in a 15-year-old student wrestler. He had a 3*3cm sized non-inflammatory alopecia with black dots on the right occipital area of the scalp. The diagnosis was established by a hght microscopic examination of the affected hairs and by mycological studies from cultures. To our knowledge, this is the first case in which T. tonsurans has been isolated in Korea, It is likely that the student acquired the infection through contact with a foreign wrestler during interaational games and practice. We should be concerned about the potential of spread of this infection in our country.
