PURPOSE: To correlate the CT findings of renal cell carcinomas with nuclear grading in histopathology. MATERIALS AND METHODS: Preoperative CT scans and pathologic nuclear grading of 60 surgically resected renal cell carcinomas in 55 patients were retrospectively and independently reviewed. RESULTS: As nuclear grade increased, renal cell carcinomas were more likely to be of higher stage(92% of nuclear grade III renal cell carcinomas was of stage Ill, all Grade IV tumors were of stage IIIb or higher) and greater size(84% of grade III tumors and 100% of grade IV tumors>5cm in size) at presentation, and appeared more heterogeneous(84% of grade III tumors and 88% of grade IV tumors showed moderate or severe heterogeneity) and less well marginated(84% of grade Ill tumors and 100% of grade IV tumors had irregular or imperceptible margins). CONCLUSION: Small well-marginated homogeneous renal cell carcinomas were either nuclear grade I or II, and were distinguishable from the more aggressive nuclear grade III or IV lesions, which generally displayed irregular margins and greater inhomogeneity.

Elephantiasis nostras, the result of recurrent skin infection or chronic lymphedema is characterized by marked skin fibrosis and massive enlargement of a body part. We present a case of elephantiasis nostras due to chronic recurrent erysipelas which affected the lower extremities in a 62-year-old man. The patient had had persisting non-pitting edema, and tender multiple verrucous brownish plaques and nodules on both lower legs for 1 year. On histological examination, there was hyperkeratosis and papilomatosis in the epidermis, fibroplasia, dilated thick walled venules and collagen fibers oriented vertical to the skin surface, and hyperplasia of eccrine ducts in the dermis.

The authors reviewed the charts of 128 patients(160 eyes) who underwent vitrectomy for the proliferative diabetic retinopathy from January 1993 to December 1995 and the results were analyzed in terms of visual efficiency. At the conclusion of the study, visual acuity improved in 96 eyes(60%), unchanged in 33 eyes(21%) and in 31 eyes(19%) became worse. Visual efficiency was increased from 11.9% preoperatively to 37.2% postoperatively in all patients. Patients under the age of 40 showed better results than the patients above the age of 40. The factors which affected the change in visual efficiency were age and preoperative intraocular conditions. The patients who had non-clearing vitreous hemorrhage without proliferative membrane revealed better prognostic results than the other patients. In 50 eyes (31.3%) of cases, maximal postoperative visual acuity was achieved in 4 weeks to 3 months after operation.

Thirty eyes of thirty patients with coexisting cataract and vitreoretinal disease underwent combined cataract extraction, pars plana vitrectomy and posterior chamber intraocular lens implantaion.Surgical procedures of cataract extraction included phacoemulsification(14 eyes), pars plana lensectomy(11 eyes) and extracapsular lens placed in the capsular bag in 19 eyes following phacoemulsification or extracapsular cataract extraction. Eleven eyes had sulcus fixation of posterior chamber lens following lensectomy.Postoperatviely visual acuity improved in 26 eyes(86.7%), unchanged in 3 eyes(10%) and decreased in 1 eye(3.3%). Final visual acuity was 20/200 or better in 26 eyes(86.75), and 20/40 or better in 11 eyes(36.7%). Postoperative complications included rhegmatogenous retinal detachment with proliferative vitreoretinopathy, neovascular glaucoma and endophthalmitis.Pars plana vitrectomy combined with cataract extraction with posterior chamber intraocular lens implantation maybe useful in reducing cost and providing rapid visual rehabilitation.

Santonin-kainic acid complex was evaluated as a chemotherapeutic of the mass treatment of the Ascaris lumbricoides infection in Korea. The results could be summarized as follows: The negative conversion rate was 82.9% in average in 4 treated groups. Some variations of negative conversion rate among the treated groups were noticed. The egg reduciton rate was 97.7% in average and the results were rather uniform among the three evaluated groups. By the analysis of egg reduction, it seems that the lightly infected cases whose E.P.G. were under 5,000 were resistant to treatment with the less reduced egg output. After the treatment with this complex, the number of egg discharged cases were reduced to 1.84% and the average number of discharge eggs per incompletely treated or untreated cases were reduced to 12.5% compared with the level of before-treatment egg output. The successive observations of the pattern of worm expulsion after drug intake was made. The worms were mostly expelled in the stool within 3 days, and 58.9% of total expelled worms were collected within 24-hour stool. The minimum length of the immature worms expelled was 7.6cm. Among the 659 Ascaris collected in the first-day stool from 91 rural people, 8.5% were in the range of 7.6-12.2 cm-long, immature worms. The sex ratio, male: female= 0.69: 1.

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.

Holoprosencephaly(HPE), a common developmental defect affecting the forebrain and cranioface, is etiologically heterogenous. Teratogen, chromosomal anomalies, genetic syndrome, or genetic disorder of non-syndromic HPE are usually accepted as etiology. But the severity of brain and craniofacial malformation are not associated with etiology. Individuals with microform of HPE, who usually have normal cognition and brain imaging, are at the risk of having children with HPE. Several studies on the basis of HPE gene have been performed, which shed valuable insight on normal brain development. As additional HPE genes are identified, more accurate recurrent risk counseling can be given. We experienced a case of recurrent HPE diagnosed by transabdominal ultrasound examinations at 22 weeks' gestation.
