Although intramedullary nailing is mostly used in the management of fractures in the long bone shaft, plate fixation is still alternative option in periprosthetic or metaphyseal fractures. For the rigid fixation during plating, sometimes we need wiring. Many surgeons experience slippage of wire resulting in loss of rigid fixation because plate and wire is so slippery and the diameter of bone is changing by level especially in the metaphyseal area. Wiring plate(CHO plate) was designed to prevent slippage. This plate has transverse holes for wires between screw holes on traditionally used dynamic compression plate. Sixteen fractures of long bone shaft were fixed with wiring plate and 11 cases which were followed up for more than one year were evaluated. There were periprosthetic fractures(4 cases), spiral or butterfly fractures(4 cases) and fractures of poor bone quality(two cases of malignancy and one case of osteoporosis). Nine cases were successfully reduced and the healed without loss of fixation. In two cases, delayed union and nonunion were observed due to wire breakage with plate loosening. Preliminarily, wiring plate fixation can be used for the periprosthetic fracture and one of alternative option in butterfly or spiral fracture and fracture in osteoporotic bone or pathologic fracture.

Building a database file in the medical literature using personal computer enables individualized computer user to search with a small amount of time and effort. We developed a computer program for searching medical literature. This program was developed with Clipper database language, and runs on IBM-PC-compatible computers. The data is based on the Index of Korean Journal of Urology which was revised in 1991. The program is focused on the function of retrieving and printing of keywords, authors and titles, etc. We expect more advanced and beneficial program for searching of medical literature based on this program.

Granular cell tumor (GCT) of the breast is a rare clinical entity, and is believed to be of schwannian origin and to follow a benign clinical course. A 50-year-old woman presented with a slowly growing mass in the right breast. Fine needle aspiration cytology revealed a cellular smear containing isolated or clustered cells showing round to oval nuclei with abundant oncocytic granular cytoplasm. Nuclei showed a fine granular chromatin pattern and occasional small single nucleoli. Cell boundaries were poorly defined, and naked nuclei were frequently found. Histologically, the tumor showed features of typical GCT, and immunohistochemical staining findings strongly supported the diagnosis. The present study demonstrates that GCT of the breast can mimic malignant lesions of breast both clinically and radiologically. The recognition of its cytologic features and suspicion of this lesion would undoubtedly aid the correct diagnosis of mammary GCT.

Combined resection of the spleen during total gastrectomy for gastric cancer is usually performed to remove the lymph nodes adequately and thereby achieving surgical radicality. However there is still controversy whether a total gastrectomy combined with a splenectomy can improve the survival rate. The authors retrospectively analyzed 557 gastric cancer patients, who underwent total gastrectomy at the Department of Surgery of Yonsei University during the 7-year period between 1987 and 1993, in order to investigate the influence of combined resection of the spleen upon the patients' survival. The patients were followed until March 1996, and the rate of follow up was 90.6%. The number of cases in which the spleen was saved was 101(the spleen conservation group, SC) and the number of cases in which the spleen was resected was 431(the spleen resection group, SR). Twenty-five cases were excluded due to incomplete data. Among the 431 cases for whom splenectomy was done, 343 were cases in which spleen was the only organ removed other than the stomach (SOR). For the other 88 cases, at least 1 more organs were resected along with the stomach and the spleen(Sp combined). There were no significant differences in the clinical characteristics such as age, sex ratio, tumor size, depth of invasion, nodal stage, TNM stage and histological type between SC and SOR group. In terms of the nodes removed during operation, there was significant difference between the SC and the SOR groups. Also, the Sp combined group showed significant differences in terms of tumor size, depth, nodal stage, TNM stage, and removed nodes. The overall 5-yr survival rate for the spleen conservation group(SC, N=101) was 61.2% and the survival rates according to TNM stage were 94.0% for stage I, 94.1% for stage II, 30.0% for III, and 0.0% for stage IV. The overall 5-yr survival rate for the 343 patients with splenectomy(SOR) was 51.9%, and the survival rates according to TNM stages were 88.7% for stage I, 57.0% for II, 44.0% for III, and 10.8% for stage IV. The overall 5-yr survival rate for the 431 patients with splenectomies or with splenectomies and multiple organ resection(SR) was 48.2%, and the survival rates according to the stages were 88.2% for stage I, 60.2% for II, 41.5% for III, and 6.8% for stage IV. The overall 5-yr survival rate was higher in SC group than in the SOR or the SR groups, but there was no statistical significance to this difference (p>0.05). In a compared according to the TNM stage, the SC group showed better survival rates in the relatively early stages (I, II) than the SOR or the SR groups did; in advanced stages (III, IV), the SOR and the SR groups showed better survival rates than the SC group. However, there was no statistically significant differences in survival among the three groups. These results suggest that during a total gastrectomy, it may be better to save the spleen in early stages of gastric cancer and that it may be better to resect the spleen for adquate lymphadenectomy in grossly advanced stages. To identify statistical difference in survival, it might be necessary to perform a randomized prospective study.

PURPOSE: The increasing use of ultrasonography has allowed for an increase in the of the detection of congenital hydronephrosis, and the clinical outcomes of congenital hydronephrosis are widely varied. In this study, the necessity of voiding cystourethrography in neonate with hydronephrosis to rule out vesicoureteral reflux (VUR) was evaluated. METHODS: Between January 2004 and December 2007, we reviewed the medical record of 157 childrens with congenital hydronephrosis detected within 1 month of age. The severity of hydronephrosis was graded by SFU (Society of Fetal Urology) system, and anterior posterior pelvic diameter (APPD). We evaluated the relationship between severity of hydronephrosis and incidence of VUR by using SPSS windows version 16.0. A P-value<0.05 is considered to be statistically significant. RESULTS: Total renal unit number was 254, and 20(7.8%) renal units had VUR. We did not find any relationship between hydronephrosis grade the presence of VUR grade (P>0.05). In addition, there was no statistical significance between APPD, laterality of hydronephrosis and VUR incidence. However, renal units with VUR had lower spontaneous resolution rate (P<0.05), compared to renal units without VUR. CONCLUSION: In this study, there was no statistical significance between the severity of hydronephrosis and presence of VUR. Therefore, voiding cystourethrogram is recommended for all children with hydronephrosis to rule out VUR, regardless of the severity of hydronephrosis.

Cytomegalovirus (CMV) infection is prevalent worldwide, although the symptomatic illness is usually confined to immunocompromised individuals. It can produce stomatitis, esophagitis, gastritis, duodenitis, and ulceration of the esophagus, stomach, duodenum, ileum, and colon within the gastrointestinal tract. Bleeding and perforation can also occur at these sites. The most common site of intestinal perforation is the colon, followed in frequency by the distal ileum and appendix. Herein, a recently experienced case of ileal perforation due to a CMV infection, in a patient with acquired immunodeficiency syndrome is reported, with a review of the literature.

OBJECTIVES: Study results of association between dopamine transporter gene(DAT1) and attention deficit hyperactivity disorder(ADHD) were not conclusive. Distribution of DAT1 polymorphism is variable according to ethnicity. Ethnic differences in the distribution of DAT1 can be an impediment to apply previous findings to Korean ADHD. This study was to examine the association between DAT1 and ADHD, and the risk allele of ADHD among DAT1 polymorphism in Korean. METHODS: DNA extracted from blood of 100 normal controls and 44 ADHD patients. DAT1 with variable number of tandem repeats(VNTR) were determined using polymerase chain reaction. The differences of allelic frequency distribution and genotype frequency distribution between patient group and control group were tested with Fisher's exact test. The pairs of allele and of genotype with difference between the two groups were selected by Fisher's excat test adjusting p-values with permutation method. Odds ratios of two alleles and of two genotypes between the two groups were computed. RESULTS: There was association between DAT1 and ADHD(genotype: p<0.05, allele: p<0.05. Patients with ADHD were more likely to have 440 base pairs than 480 base pairs comparing to controls (OR=4.46, 95% CI: 1.44-13.75). Patients with ADHD were more likely to have 9/10 genotype than 10/10 genotype comparing to controls(Odd Ration=3.74, 95% Confidence Interval: 1.11-12.61). CONCLUSIONS: We found the association between DAT1 and ADHD, and possible risk allele of Korean ADHD. Replication of the results in larger sample is needed.
