PURPOSE: The variety of outcomes in patients with stage II colorectal carcinomas might be due to understaging caused by an inadequate number of lymph nodes (LNs) being examined. The aim of this study was to determine if any number of examined LNs reflects a reliable node-negative staging for colorectal carcinomas (CRCs). METHODS: Data on 241 patients (132 males) who underwent potentially curative resections for pT3 and pT4 CRC were reviewed. The patients ranged in age from 21 to 87 (mean: 58.2) years with a median follow-up of 43 (range: 7~96) months. The relationship between the number of LNs harvested and both the 5-year disease-free survival (DFS) and the overall survival (OS) rates were assessed for stage II CRCs. RESULTS: A median of 15 LNs (range: 3~104) was harvested per tumor specimen, and lymph-node metastases were present in 107 cases (44.4%). The proportion of lymph-node metastases increased as a function of the number of LNs harvested (P=0.0002; 95% confidence interval, 0.3333~0.8138). The number of LNs revealed to be the best number for dividing stage II patients into subgroups with different DFS and OS rates was ten. The 5-year DFS and OS rates of the 48 patients (35.8%) with nine or fewer LNs harvested were 68.6% and 76.8%, respectively, whereas those of the 86 patients (64.2%) with ten or more LNs harvested were 87.2% and 91.9%, respectively (DFS, P=0.0082; OS, P=0.0303). Moreover, there were no statistical differences between the node-negative patients with nine or fewer LNs harvested and the 67 stage III patients with N1 in respect to the DFS (68.6% vs. 56.7%; P= 0.2031) and the OS (76.8% vs. 68.3%; P=0.2772) rates. CONCLUSIONS: This study suggests that examining a greater number of lymph nodes increases the likelihood of accurate nodal staging and that a minimum of ten LNs per surgical specimen should be harvested and examined to label a pT3 or pT4 CRC as node-negative.

OBJECTIVES: To determine if hysterectomy with or without ovarian preservation is asso-ciated with obesity in premenopausal women. METHODS: 581 women for routine check up from Jan. 1985 to Dec. 1995 in the depart-m ent of Gynecology at Korea Veterans Hospital were included. The obesity was evaluated by BMI(body mass index) scores. 80% of hysterectomy were confirmed from the hospital records. The age, weight, height, blood pressure, menstr- ual history, history of DM and hypertension, social history of alcohol and smoking and other cardiovascular risk factors such as cholesterol, HDL-cholesterol, triglycerides were checked. The 248 women with natural postmenopausal status before hysterectomy, taking hormonal replacement therapy after hysterectomy and having performed hysterectomy due to malign- ancy were excluded. RESULTS: All women performed hysterectomy were in premenopausal status in this study. Therefore, the final numbers of subjects included in the analysis was 333. Hysterectomy wit- hout ovarian preservation were performed in 58 cases and hysterectomy with ovarian pres- ervation were in 57 cases. The 218 premenopausal cases which did not performed hystere- ctomy were considered control group. BMI scores were higher in cases without ovarian pres- ervation than with ovarian preservation. And BMI score was associated with the postoper- ative duration in hysterectomy with ovarian preservation. CONCLUSIONS: We suggest that hysterectomy without ovarian preservation in premeno- paussal women were associated with increased obesity, especially BMI scores.

PURPOSE: To investigate the effects of Anti-TNF-alpha (infliximab, Remicade(R), Shering-Plough) on refractory uveitis. METHODS: A retrospective observational survey was conducted on 12 eyes of 10 patients with refractory uveitis. These patients had no response to immunosuppresants or systemic steroid therapy and were intolerable due to drug toxicity. After an intravenous injection of Anti-TNF-alpha, best corrected visulal acuity was measured. Improvement in inflammation was then observed at the first, third and last month of follow-up. RESULTS: Patients were observed for a mean period of 15 months. They received anti-TNF-alpha intravenously, ranging from one to eleven infusions. After infusion with Anti-TNF-alpha, remission of intraocular inflammation was evident in all patients within 9.7 days. Best corrected visual acuity also improved at the first, third, and last month of follow-up. Two patients were infected by tuberculosis and mumps respectively. CONCLUSIONS: There was an effect on refractory uveitis with anti-TNF-alpha therapy. Many participants may also require further evaluation after treatment.

PURPOSE: To analyze the results of a 5-12 year (mean, 7 years, 5 months) follow-up of femoral revision THA using the Wagner(R) stem. MATERIALS AND METHODS: Of 79 revision THA patients enrolled in the study between March 1991 and January 2000, there were 64 cases of aseptic loosening (69 hips, 44 males and 20 females) during a minimum 5-year follow-up. In addition, postoperative complications and clinical and radiographic results were evaluated. RESULTS: The Harris hip score improved from 48.6 to 91.2 points, postoperatively. There were 3 revisions due to failed stem fixation and aseptic loosening. The Kaplan-Meier survivorship analysis, with failure defined as a removal of the Wagner(R) stem, revealed a 97.1% survival at a 12-year follow-up. Besides the revisions, there were 66 hips that were hip-related symptom-free. However, there was claudication in 1 case. Radiographic findings included subsidence of the implant (5 cases, 7.5%, all less than 10 mm), calcar femorale atrophy (4 cases, 6.0%), stress shielding (4 cases, 6.0%), and heterotopic ossification (5 cases, 7.5%). Postoperative peroneal nerve palsy (2 cases) resolved completely within the following 6 months. CONCLUSION: We obtained a stable fixation and satisfactory results in the cases we studied using the Wagner(R) revision stem.

PURPOSE: Recently, incidences of chronic cough with allergic disease have been increased. The identification of specific allergens for chronically coughing children is significant for diagnosis, proper treatment and prevention. The aim of this study was to identify significant contributors for sensitization in chronically coughing children. METHODS: A total of 106 children, aged 1-6 years, visiting for chronic cough(>3 weeks), were tested for inhalant multiple allergosorbent assay(MAST), eosinophil count and total IgE. Parents completed a questionnaire on past history of atopy(infantile eczema) and bronchiolitis, family history of allergy, breastfeeding, smoking, pets and floor coverings at home. RESULTS: Significant contributors for sensitization were:age(4-6 years), infantile eczema, positive family history of allergy and smoking by family. CONCLUSION: We were able to identify significant contributors for sensitization in chronically coughing children.

PURPOSE: The prevalence of obesity in children is increasing rapidly. Epidemiologic studies suggest that obesity induced atherosclerosis may start in childhood. We investigated whether obese children show early abnormalities of the arterial wall and endothelial dysfunction. METHODS: Thirty-eight obese children(14-16 years old of age, male, body mass index 29.40+/-3.18 kg/m2) and forty-five age and sex-matched healthy control children(body mass index 18.43+/-1.01 kg/ m2) were enrolled. Their carotid artery intima-media thickness(IMT) and brachial artery flow-mediated dilation(FMD) response were measured by high-quality ultrasound system, and compliance, distensibility, stiffness index, incremental elastic modulus and wall stress were calculated by equation. In addition, we looked at the relations between these arterial features and metabolic cardiovascular risk factors. RESULTS: The obese children had significantly increased IMT(0.52+/-0.09 mm vs 0.40+/-0.07 mm, P< 0.001) and markedly impaired FMD(7.35+/-7.78 percent vs 20.34+/-16.81 percent, P<0.001) than the healthy controls. But the compliance and distensibility were lower, and the stiffness index, incremental elastic modules and wall stress were higher in the obese group than the control group, but not statistically significantly. Body mass index was highly associated with increased IMT(r=0.612, P< 0.001) and reduced FMD(r=-0.414, P<0.001). CONCLUSION: We showed the deleterious effect of child obesity on both early functional and structural atherosclerotic markers. The ultrasonic findings will be used for screening and follow up markers to identify high-risk patients among obese children.

BACKGROUND AND PURPOSE: Negative findings on diffusion-weighted imaging (DWI) does not exclude the possibility of brainstem infarction, particularly in the acute stage of medullary lesion. Our aim was to investigate the false-negative rate of DWI in patients with acute lateral medullary infarction. METHODS: We applied DWI to 26 patients with a clinical diagnosis of lateral medullary infarction within 72 h of the onset. We assessed relationships between initial DWI findings and time-to-MRI (the time between onset of symptoms and initial DWI), number of clinical symptoms and signs, and final lesion volume. RESULTS: There were 8 cases (31%) of false negatives in the initial DWI results. The occurrence of false-negative DWI findings decreased significantly as the time-to-MRI increased (P=0.014). However, the false-negative rate was not significantly correlated with the number of clinical symptoms and signs or the final lesion volume. CONCLUSIONS: The diagnosis of lateral medullary infarction should not be ruled out on the basis of early negative DWI. To confirm the lesion, follow-up DWI or further MRI should be performed in cases with early negative DWI results
