Estrogen and progesterone receptors exist in the epithelial and stromal cells of the endometrium. Proliferative disorders of the endometrium may be associated with autocrine and paracrine actions of estrogen and progesterone in epithelial and stromal cells. This study was performed to evaluate the differences estrogen and progesterone receptor(ER/PR) expression in the epithelial and stromal cells of endometrial hyperplasias and adenocarcinomas using immunohistochemical methods. Immunohistochemical analysis of proliferating cell nuclear antigen(PCNA) was done to evaluate a possible correlation between PCNA and hormone receptor expression. Evaluation was based on samples from 31 simple hyperplasias, 30 complex hyperplasias, and 32 adenocarcinomas. The immunohistochemical expression of ER, PR and PCNA in epithelial and stromal cells were examined according to a scoring system based on the percentage of positive cells and the staining intensity. The results were as follows; 1) The expression of ER and PR in epithelial cells showed a graded, significant decreases in simple hyperplasia, complex hyperplasia and endometrial carcinoma, in that order(ER: P=0.008, PR: P= 0.026). 2) PR expression in the stromal cells showed a significant decrease between hyperplasia and adenocarcinoma(P=0.003). The difference in ER expression was not significant. 3) In stromal cells, the decrease in PR expression was more prominent than the decrease in ER expression when complex hyperplasia was compared to simple hyperplasia. 4) The PCNA expression in simple and complex hyperplasia and adenocarcinoma was not higher than the expression of PCNA in nomal proliferative endometrium. There was no significant difference in PCNA expression between simple and complex hyperplasia and adenocarcinoma(P=0.073). 5) A negative correlation between PCNA and ER/PR expression was not demonstrated in simple and complex hyperplasia, or in adenocarcinoma. Endometrial hyperplasia and adenocarcinoma are probably related to a paracrine action of estrogen and progesterone in epithelial and stromal cells. A progressive loss of PR expression in stromal cells may induce abnormal proliferation of endometrium due to a disrupted hormonal balance.

We studied 600 normal lower extremities of Korean students of elementary school in order to establish normal values for the rotational profile and to define any differences between ethnic groups. Rotational profile examined at this study included medial and lateral rotation of the hip and thighfoot angle. The mean value of medial rotation of the hip was 48 degrees with a range of 35 to 64 degrees in male subjects, and 50 degrees with a range of 35 to 60 degrees in female subjects. The mean value of lateral rotation of the hip was 57 degrees with a range of 43 to 75 degrees, and 53 degrees with a range of 40 to 72 degrees in female subjects. Unlike medial rotation, lateral rotation of the hip was greater in male than in female subjects by a mean difference of 4 degrees(T-test, p<0.05). The mean value of thigh-foot angle was 10 degrees with a range of -2 to 23 degrees in male subjects, and 12 degrees with a range of 0 to 21 degrees in female subjects. The total range of hip rotation was slightly greater in Korean than in Caucasians or in Chinese, but, to conclude this, more large study by the same methods will be needed in other areas of Korea.

A clinical and histologic survey was done on 71 cases of basal cel carcinoma(BCC) filed at Department of Clinical Fathology, Kang Nam, Han Kang, and Kang Dong Sacred Heart Hospital during past 13 year s from 1979 to 1991. The results were summerized as follows: 1. Of all malignant skin tumors BCC accounted for 31.6%. The frequency of BCC in the total number of outpatients visiting the Department of Dermatology was 0.06%. 2. The ratio of men to women with HCC was 1:1.03. 83.8% of the pat.ients with BCC were older than the age of l0 years with the mean age of 56.9 years. 3. 83.8% of the BCC appared in the face, especially on the nose(25.4%), eyelid(20.3%). 4. On the basis of classification of Lever et al, the solid type(66.7% ) was the most com mon histologic pattern, followed by the adenoid(8.8%), pigmented(8.8%), and etc. By the classification of Farmer et al, the nodulocystic type(35.1% ) was the most common histologic pattern followed by infiltrative(31.6%), adenoid(8.8%), pigmented(8.8%), and etc. By the classification on Sexton et al, in the order of decreasing frequency, liistologic subtypes were the nodular(43.9%), mixed (22.8%), infiltrative(19.3%), supeficial(3.5%), morpheic(3.5%), and micronodular(3.5%).

A 40-year-old woman presented with a pruritic erythematous eroded patch on the right labium majus which had been for 3 years. Histopathological findings were consistent with superficial basal cell epithelioma. Basal cell epithelioma of the labium majus is a rare neoplasm and its clinical appearance is usually nodular. In contrast to the other types of basal cell epithelioma, the superficial type occurs mainly on the trunk. We report a case of superficial basal cell epithelioma arising from the labium majus.

Malposition of the extracorporeal membrane oxygenation (ECMO) venous cannula in the azygos vein is not frequently reported. We hereby present such a case, which occurred in a neonate with right-sided congenital diaphragmatic hernia. Despite ECMO application, neither adequate flow nor sufficient oxygenation was achieved. On the cross-table lateral chest radiograph, the cannula tip was identified posterior to the heart silhouette, which implied malposition of the cannula in the azygos vein. After repositioning the cannula, the target flow and oxygenation were successfully achieved. When sufficient venous flow is not achieved, as in our case, clinicians should be alerted so they can identify the cannula tip location on lateral chest radiograph and confirm whether malposition in the azygos vein is the cause of the ineffective ECMO.

Following chemotherapy for acute myelomoncytic leukemia, an 3-year-old boy developed several painful erythematous indurated patches at previous sampling sites and at the site where an arm board and adhesive tape were used in securing an intravenous infusion set. The lesions rapidly progressed to ulcers with central black eschars. Biopsies and cultures demonstrated a fungus, Aspergillus flavs, as the etiologic agent, without evidence of systemic dissemination. Local care, including s irgical debridement, were performed. The patient also received treatment with intravenous; amphotericin B followed by oral itraconazole. Six months later, the skin lesions had healed, leaving some scar and deformities.

A total of 53 patients infected with Taenia solium were treated with praziquantel in two different dose levels. Twenty-six cases were treated with praziquantel in a single oral dose of 5 mg/kg body weight. All cases except one were completely cured. The cure rate was 96.2 per cent. The other 27 cases were treated with a single dose of 10 mg/kg body weight. All cases were completely cured and revealed a cure rate of 100 per cent. Side effects were mild and transient. About half of the cases complained of a mild abdominal pain. Soft stool or diarrhea and dizziness were observed in some cases. Tests on clinical hematology, serum biochemistry and urinalysis were performed immediately before and one day after treatment in all cases. There were no significant abnormalities detected in these tests.
