Ovarian cysts in the newborn are uncormnon. Fetal ovarian cysts are being diagnosed with inaeasing fiequency with development of obstetrical sonography. Most of these cysts are found within the first few months of life and have no clinical significance. But, a large ovarian cyst would be founded antenatally with sonography. A large ovarian cyst can cause life-theatening complications during parturition and in the neonatal period. We have experienced a case of fetal ovarian cyst in a 32-year-old primiparous woman with antenatal sonography and report our experience with a brief review of literatures.

PURPOSE: To compare the efficacy of Bimix solution (27.3 mg/ml papaverine and 0.9 mg/ml phentolamine) versus Trimix solution (18.8 mg/ml papaverine, 0.6 mg/ml phentolamine and 6.3ug/ml prostaglandin El) in terms of erectile response and complications. MATERIALS AND METHODS: We comparatively analyzed the erectile response and the incidence of pain, prolonged erection (>4 hours), and corporal fibrosis of either medication in the 155 impotent patients who used Bimix solution for intracavernous pharmacotherapy (mean duration: 15 months) and thereafter used Trimix solution (mean 12 months). RESULTS: Erectile response to Trimix solution was significantly better than Bimix solution (p<0.01). The mean dose of Bimix solution was higher than Trimix solution (0.43 ml. vs. 0.34 ml, p<0.05). The severe pain enough for impediment to ntercourse occurred in 6.5% of the Trimix group, while no patient of the Bimix group experienced (p<0.01). The corporal fibrosis was noted in 8.4% of the Trimix group and 16.1% of the Bimix group. However, there was no significant difference between the two groups (p=0.08). The incidence of prolonged erection was significantly lower (p<0.05) in the Trimix group (2.6%) than in the Bimix group (12.3%). A total of 139 patients (89.7%) finally selected Trimix solution. CONCLUSIONS: The Trimix solution was more effective and safer than Bimix solution for the treatment of erectile dysfunction.

Glutathione S-Transferase (GST) is a conjugation enzyme in the metabolism of exogenous and endogenous lipophilic compounds for their excretion and detoxification. Acidic isozyme of GST, GST-Pi, has been recognized as a preneoplastic marker in the experimental hyperplastic nodules of liver in rats, and GST-Pi is abundant in the squamous cells of the skin, also. This histochemical study was carried out to evaluate the distribution and the relationship between the differentiation status of squamous cells in dysplastic or neoplastic epithelium in various organs. The human placental form of glutathione S-transferase (GST-Pi) were stained immunohistochemically with specific anti GST-Pi rabbit antibody in 23 cases of human squamous cell carcinomas. The patients consisted of 14 cases from the uterine cervix, 3 cases from the esopahgus, 3 cases from the lung and 3 cases from the larynx. The results obtained were as follows; 1. Basal cells in normal mucosa were stained negative for GST-Pi while superficial keratinocytes were stained moderately positive. Basal dysplastic cells were stained negatively or weakly positive. Carcinoma cells especially large cells either keratinizing or nonkeratinizing were stained moderately to strongly. Carcinoma cells surrounding keratin pearl were strongly reacted with GST-Pi than other carcinoma cells. 2. Differentiated cells of squamous cell carcinoma showed moderate to strong positive reaction to GST-Pi staining irrespective of its site of origin. 3. Therefore, Immunohistochemical staining pattern of GST-Pi in various squamous carcinoma cells showed similar immunohistochemical reaction to the GST-pi, which is closely correlated to the degree of differentiation, keratinigation and also suggested that squamous carcinoma cells had abundant GST-Pi related detoxifying system.

Neurilemmomas of the extremities are nerve sheath tumors involving peripheral nerves of the extremities. We analyzed MR images of 16 surgically proved tumors in 12 patients and compared the MR images with gross pathologic specimens in two tumors (2/16). Spin echo T1-weighted images were obtained in all the patients but T2-weighted images were obtained in six patients with a gradient echo technique. Gadolinium dimeglumine enhanced T1-weighted images were obtained in 11 patients (15/16). Signal on T1-weighted images was iso or slightly higher than that of the adjacent muscles. Signal on T2-weighted images ranged from homogeneous high to heterogeneous. After Gadolinium injection, all the 15 tumors showed enhancement. Small sized tumors were enhanced homogeneously but there was a tendency tobe enhanced heterogeneously to the central portion with peripheral rim enhancement as the size of the tumors increased. Pathologically, the enhanced portion was correlated the with solid protion was correlated the with solid portion of the tumors. Also encapsulation of the mass (12/16), suspended nerve strings (9/16) and bony erosion (1/16) were detected. MR characteristics of neurilemmoma include heterogeniety on enhanced T1 and T2 weighted images, encapsulation, and suspended nerve strings. Signal heterogeneity on enhanced T1 and T2 weignted images may be attributed to the variable cellularity, cystic changes, vascularity and focal hemorrhage of the tumors.
