1.Keratinizing Desquamative Squamous Metaplasia of the Upper Urinary Tract: A case report.
Korean Journal of Pathology 1991;25(1):76-80
Keratinizing desquamative squamous metaplasia of the transitional epithelium occurs rarely in the upper urinary tract, especially in the ureter. It is associated in most cases with long-standing chronic inflammation but the exact pathogenesis is unknown, and the relationship to cancer has continued to be controversial. More cases should be accumulated for a better assessmnt of this lesion. Recently, we experienced a case of keratinizing desquamative squamous metaplasia in the renal pelvis, adjacent calyces and ureter following acute and chronic pyelonephritis. Herein, we are presenting our case with a review of literatures.

BACKGROUND: Hydrofluoric acid(HF) is one of the strong stirritating, corrosive and poisonous inorganic acid, The HF burns are occuring with ever-increa firifrequency due to the wide use of this acid in industrial fields, such as electronics and semicor tor industries. OBJECTIVE: The purpie of this study is to quantiate theound depths produced by varying concentrations of HF aiud to suggest the treatment guideline. METHODS: Uarious cinicentrations of HF(5%, 25%, 50%),were applied to two pairs of test sites on a guinea pig's back in a uniform fashion with cotton-tip applicators and then the histopathologic changes of guinea pig skin were observed. RESULTS: 1, In the 5% HF applied group, intracellular edema vaobserved in the epidermis after 12 hours. After 3days, epidermal cell necrosis was observed. 2. In the 25% HF applied group, intraepidermal vesice was observed after 6hours. After 12hours, inflammatory cell infiltrations were observed in the apper dermis and then after 3days, dermal necrosis was oberved. 3. In the 50% HF applied group, epidermal cell necros After 6hours, liquefaction degeneration in the epidermis an was observed focally after 3hours. iflhmmatory cell infiltrations in the upper dermis were observed. After 2days, dermalar.ecrosis was observed and then after days, the reaction was at its peak and subcutaneous tissuc. necrosis was observed. CONCLUSION: This study showed that a higher concentrator HF exposure enhances The penetration of HF. For treatmi not alcohloic solution of a quarternary ammonium for avintralesional injection of calcium gluconate within 24 hours of HF and a longer period after we suggest wet dressing with an concentration of HF burn and high concentration of HF burn.

Since 1983, the transtrochanteric rotational osteotomy has been performed in 38 hips of 36 patients for the nontraumatic avascular necrosis of the femoral head at the department of orthopaedic surgery of Seoul National University Hospital. Out of them, 26 hips(18 cases of Sugioka grade I and 8 cases of Sugioka grade II ) were followed up for more than 1 year. The average period of follow-up was 3 years and 5 months(range, 1 year and 2 months to 7 years). These cases include 3 cases of failure before 2 years after operation. Overall, the result was satisfactory in 20 cases(77%)out of a total of 26 cases(success in 18 cases(69%)and good in 2 cases(8%)). The results of the grade I lesions(14 cases of success and 1 case of good result out of 18 cases) were better than those of the grade I lesions(4 cases of success and 1 case of good result out of 8 cases). Complications occurred in 5 cases. These include an ectopic ossification, a stress fracture of the neck, a nonunion of the osteotomy site, a nonunion of the greater trochanter and a delayed union of the greater trochanter. There were 6 cases of failure. For the 4 cases of them, hip replacement arthroplasy was performed. The MRI images axial to the longitudinal axis of the femoral neck gave excellent information for the operation.

Korean Journal of Pathology 1992;26(2):201-203
A case of pulmonary arteriovenous fistula in a 8-year-old boy who presented with easy fatigability and cyanosis for 4 months, is described. Grossly, there was a large vascular anomaly measuring 2x2 cm in the center of the removed right lower lobe. Microscopically, the lesion consisted of dilated arterial and venous structures resembling a cavernous hemangioma. Subintimal fibrosis and attenuated vascular structure lacking elastic fiber and representing A-V shunt were also noted in the lesion.

OBJECTIVE: The aim of the study was to evaluate the corelation between an expression of lectins and survival of patients with squamous cell carcinoma of uterine cervix. METHODS: The cell surface carbohydrate profile of formalin-fixed paraffin embedded tissue section of squamous cell carcinoma of the uterine cervix was evaluated using ulex europaeus agglutinin(UEA-1), peanut agglutinin(PNA), dolichos biflorus agglutinin(DBA), soybean agglutinin(SBA) and lotus tetragonobus lectin(LTL) by the avidin-biotin complex method. Fifty-one cases of squamous cell carcinoma and 10 cases of normal squamous epithelium of the uterine cervix were selected from the file which were treated during Jan. 89 to 31 Dec. 1992 in Department of Obstetrics and Gynecology, Korea University Hospital. RESULTS: UEA-1 and LTL were negative in normal cervix while positive in 76.5%, 47.1% of squamous cell carcinoma respectively, and useful markers for differential diagnosis between normal and squamous cell carcinoma. SBA and LTL were useful for differential diagnosis of keratinizing and non-keratinizing squamous cell carcinoma. UEA-1 may play an important role in lymphovascular invasion of squamous cell carcinoma of the uterine cervix. CONCLUSIONS: There was no correlation among clinical staging, patient's survival and lectins binding in squamous cell carcinoma.

PURPOSE: To evaluate high signal intensity of nontumorous conditions of corpus callosum on T2-weighted MR images. MATERIALS AND METHODS: Fourty nine patients with nontumorous high signal intensities involving corpus callosum on sagittal T2-weighted image were restrospectively analyzed. Nontumorous condition of corpus callosum were diffuse axonal injury(DAI, 19 cases), cerebral infarctions(16 cases), multiple sclerosis(MS, 5 cases), Wilson's disease(2 cases) and hydrocephalus(7 cases) that were diagnosed by clinical and MR findings. Numbers, configuration, involved thickness and sites of high signal intensities of corpus callosum were analyzed. RESULTS: DAI and infarctions showed either single or multiple lesions. MS and hydrocephalus showed multiple lesions, but Wilson's diseases showed single lesion. In DAI, infarctions and MS the lesions involved any part of corpus callosum, splenium in WIIson's disease, and all parts of corpus callosum in hydrocephalus. Wilson's disease showed only partial thickness involvement, and others involved partial or full thickness of corpus callosum. Configuration of high signal intensity was linear in most cases of hydrocephalus, and oval in Wilson's disease, and oval and confluent in MS, and variable in DAI and infarctions. CONCLUSION: High signal intensities of nontumorous conditions of corpus callosum revealed variable findings, and therefore, analysis of nontumorous high signal intensities of corpus callosum is not made by only MR findings but by conjuction with clinical aspects.
