PURPOSE: We evaluated if VEGF (Vascular Endothelial Growth Factor)-immunoreactivity is associated with tumor stage or grade in RCC (renal cell carcinoma), and specifically, if it could serve as a prognostic i ndicator in terms of survival. MATERIALS AND METHODS: Histologic samples of 54 patients in whom radical nephrectomy due to RCC (clear cell type exclusively) from January 1995 to July 1999 were included in this study. VEGF-immunoreactivity was classified as 0 to 3+ according to the ratio of VEGF-positive cells in randomly selected multiple tumor areas. Histologic differentiation was classified according to Fuhrmann's classification and staging was made with TNM classification. RESULTS: The correlation between grade and VEGF-positivity was statistically significant using chi-square analysis. Among the 3 patients with grade I, showed 2, 1, 0 for VEGF 1+, 2+, 3+ respectively. In grade II the cases were 11, 7, 3 respectively. In grade III the cases were 3, 10, 11, and in grade IV the cases were 1, 2, 3 respectively. The correlation between stage and VEGF-positivity didn't show statistical significance. The survival rate for VEGF during the period was 100%, 90%, 76.5% for VEGF 1+, 2+, 3+ respectively. The survival rate for grade was 100%, 100%, 83.3%, 66.7% for grade I, II, III, IV respectively. The survival rate for stage was 95.2%, 85.7%, 87.5%, 66.7% FOR STAGE I, II, III, IV respectively. In the same grade, survival rate decreased apparently according to the increase of VEGF-positivity. For example, in the same grade III, the survival rae was 100%, 90%, 72.7% for VEGF 1+, 2+, 3+ respectively. CONCLUSIONS: The results of this study is that VEGF is correlated with tumor grade and the higher VEGF expression, the lower the survival rate, so we can predict the prognosis by VEGF immunohistochemical staining for supplement of grading system. VEGF alone can be a good predictor for survival, and importantly in the same grade, we can differentiate patient's prognosis with VEGF.

This study examined the cross-sectional association of body fat distribution with hypertension as well as the superiority of medical calf skinfold measured as peripheral fat distribution over the conventional triceps skinfold using 450 Korean Navy divers selected by authors' convenience in 1990. Their mean age was 27.9 and range of it was 19-51. The centrally located body fat was approximated by subscapular from these skinfold measures to reflect central versus peripheral fat distribution pattern: 2 ratios and 2 differences. After controlling age and overall obesity (body mass index), prevalence odds ratios of the 2/4, 3/4, 4/4 quartiles of subscapular skinfold comparing with lowest 1/4 quartile were 2.05 (95% confidence interval, CI 1.18-3.59), 2.02 (95% CI 1.06-3.86), 4.00 (95% CI 1.99-8.06) respectively. The difference of subscapular and medical calf skinfolds was associated with hypertension (odds ration 2.45, 95% CI 1.28-4.68 comparing highest with lowest quartiles). Triceps and medical calf skinfolds alone did not show any odds ratio not including unity. The adjusted odds ratios were generally reduced in small magnitude compared with crude odds ratios not adjusted for age and overall obesity. The medical calf skinfold appeared to be more representative of peripheral body fat distribution than triceps skinfold. These findings suggest that central fat distribution rather than peripheral distribution is associated with hypertension independent of age and overall level of obesity and medical calf skinfold may replace conventional triceps skinfold in predicting peripheral distribution of body fat.

OBJECTIVE:To compare pregnancy outcomes between obese and nonobese women and to determine the effect of gestational weight gain on pregnancy outcome in obese women. METHODS: A retrospective cohort study was conducted comparing 100 obese and 300 nonobese women who delivered a singleton live birth at Yeungnam university hospital from June 1998 to Dec 1998. Morbid obesity was defined as a body mass index greater than 30. The incidence of selected perinatal and neonatal outcome was assessed for two groups. RESULTS: Morbidly obese patients were more likly to experience pregnancy complications including gestational diabetes mellitus, preeclampsia, placental abruption, fetal distress, meconium aspiration, cesarean delivery & birth trauma. However, these were not affected by gestational weight gain in morbidly obese women. Weight gains more than 12kg were strongly associated with birth of a large for gestational age(LGA) neonate, however, poor weight gain did not appear to incrcase the risk of delivery of a low birth weight neonate. CONCLUSION: To optimize fetal growth, weight gain of 7-12kg for obese women appear to be appropriate. To reduce the risk of delivery of an LGA neonate, the optimal gestational weight gain for obese women should not exceed 12kg.

The authors have reviewed 63 resistant clubfeet of 40 patients who were treated by modified Turco's operstion at the Department of Orthopaedic Surgery, Seoul National University Hospital during the eight years period from July, 1979 to June, 1987. The procedure performed by the senior author(D.Y.L.) is essentially similar to Turco's original technique, but with the following modifications :(a) A curvilinear skin incision instead of Turco's straight oblique incision. (b) Aponeurotic tenotomy of the abductor hallucis. (c) Medial capsulotomies of the first metatarso-medial cuneiform joint, medial cuneiformnavicular joint and release of the medial extension of the tibialis anterior insertion. (d) Z-plastic lengtening of the tibialis posterior tendon instead of tenotomy (e) Plantar fasciotomy The average age at the time of operation was 23.4 months, the youngest being 4 months and the oldest being 6 year and 7 months. The follow-up period was minimum 12 months and maximum 6 years, the average being 27.4 months. The cases were analysed radiologically and clinically, and following observations were made. l. AP and lateral talocalcaneal angles were corrected satiafactorily in 60 feet(95%) and 59 feet(94%), respectively. The Talocalcaneal indices were corrected satisfactorily to over 40 in 60 feet(95%). 2. The talo-first metatarsal angles, which reflect adduction of the fore-foot, were corrected satisfactorily to within +10°in 55 feet(87%). 3. Good and fair results were obtained in 54 feet(86%) in the radiological evaluation. 4. Adduction deformity of the forefoot was responsible in most cases of radiologically unsatisfactory results. 5. Among 40 feet of 26 pstients who were evaluated clinically by the Wynne-Davis method, 33 feet were rated good and 7 feet were rated fair. No poor results were found clinically. 6. Senior author's modification of additional forefoot medial release is an important addition to Turco's original technique and effectively reduced unsatisfacotory results.

The effectiveness of Sulfobenzylpenicillin in the treatment of urinary tract infection was evaluated in the Department of Urology, Seoul National University Hospital during the period from May to November, 1973. Our clinical study was performed on the 28 patients who visited the outpatients clinic and admitted to the ward. These patients were studied by bacterioscopy with Gram's method of staining. and culture in blood agar plate and chocolate agar plate In this studies. the causative organisms were divided into 8 groups; E. coli (5), coagulase positive staphylococcus (5), pseudomonas (2), Corynebacterium spp. (1), a-hemolytic etreptococcus (2), N. Gonorrheae (10), Proteus (2) and KIebsiella (1). The dosage schedule was 1 gm. of Sulfobenzylpenicillin at intervals of 12 hours for consecutive 5 days in gonococcal urethritis and nongonococcal urethritis. But in upper urinary tract infections and post-operative infections, it lasted for 7 to 10 days or more. And following results were obtained. Effectiveness on Urological diseases 1) Gonococcal urethritis; Satisfactory clinical results were obtained with Sulfobenzylpenicillin for five days. Results were excellent in 5 cases, good in 4 cases and negative effect in 1 case. 2) Non-gonococcal urethritis; In this group, the therapeutic results were favorable in 90% of all cases. (excellent-4, good-5, fail-l) 3) Urethral stricture and fistula (2 cases); AII cases were responded to the Sulbenicillin. 4) Cystitis including Prostatism; Two of three cases were caused by E. coli and they had a good response to sulbenicillin. 5) Two cases of pyelonephritis and two cases of postoperative infections were studied with sulbenicillin and more than 60% of cases were effective with sulbenicillin. Side effects were not remarkable but in a few cases who received intramuscular injection, pain on the injection site was noticed.In summary, this new semi-synthetic penicillin is considered to be a useful chemotherapeutic weapon against a variety of infection in the urological field including those due to Gram negative bacilli such as pseudomonas and proteus sp.

Subsepsis allergica's main characteristics are high intermittent fever, irregular recurring exanthemata of different types, neutrophil leukocytosis, increased sedimentation rate, negative culture, no demonstrable cause and good prognosis. This disease usually oecurs in children under age of fifteen. We had opportunity to observe a case in 30 year-old fernale presenting most of the above mentioned charactristics and presumably belonging to this disease entity. Other fever producing diseases were excluded by clinical featuree, serologic tests and skin biopsy. It was treated by antibiotics and salicylate without effect, but it responded to corticosteroid.
