PURPOSE: The purpose of this study was to evaluate the validity of the cutoff size for a localized renal cell carcinoma (RCC) by assessing the survival of RCC patients according to a series of alternative size cutoff values. MATERIALS AND METHODS: The outcomes of 147 patients with localized RCC, treated by radical nephrectomy at our institution, between 1984 and 2004, were retrospectively evaluated. The mean follow-up period was 54.9+/-32.5 months. The survival of patients with tumors smaller than a specified size cutoff was compared with that of tumors larger than the cutoff, and the most discriminating cutoff identified. RESULTS: 114 and 33 patients were pT1 (77.6%) and pT2 (22.4%), respectively. There were 10 recurrences (8.8%) and 6 deaths (5.3%) in the pT1 group, and 8 recurrences (24.2%) and 8 deaths (24.2%) in the pT2 group. The differences in survival were maximized when the tumor size cutoff point was 7cm (cancer-specific survival rate: 92.0% vs. 71.5% p=0.0003, diseasefree survival rate: 88.5% vs. 69.1% p=0.0092). The next significant difference was observed with a cutoff of 4cm (cancer-specific survival rate: 96.0% vs. 83.7% p=0.0467, disease-free survival rate: 96.0% vs. 78.8% p=0.0121). CONCLUSIONS: Tumor size is an important prognostic factor in patients with an organ confined RCC. The established cutoff point of 7cm provided reasonable prognostic differences. A 4cm cutoff point is also feasible for separating groups with different survivals after a nephrectomy. Hence, the T1a/1b/T2 classification system is practical for the division of localized RCC.

Laparoscopic partial nephrectomy has been recently applied as a minimally invasive procedure. Several non-ischemic operation devices for partial nephrectomy have been developed. Two patients with small renal tumors successfully underwent laparoscopic partial nephrectomy at our institution with using a microwave tissue coagulator without any immediate complication. The renal parencyme around the tumor was coagulated using a microwave tissue coagulator with a probe 1.5cm in length. The tumor was circumscribed within the coagulated area, and partial nephrectomy was performed using scissors. Laparoscopic non-ischemic partial nephrectomy using a microwave tissue coagulator may be feasible for treating selected small renal tumors.

Testicular feminization syndrome is characterized by 46,XY karyotype, bilateral testes, absent or hypoplastic wolffian duct, female appearing external genitalia, blind vaginal pouch, and absent or rudimentary muillerian derivatives. We experienced vaginoplasty using rictus abdominis myocutaneous flap with modified Burch bladder neck suspension in a 51-year-old patient with testicular feminization syndrome combined with stress urinary incontinence.

Colorectal cancer is extremely rare in children. Unlike adult colorectal cancer, the overall prognosis of colorectal cancer in children is poor. Delayed diagnosis, advanced stages of the disease at presentation, and mucinous type of histology are the major determinants of poor outcome in childhood. A 13-year-old boy with abdominal pain visited our hospital. Physical examination andabdominal ultrasonography identified acute appendicitis with perforation. He underwent appendectomy and then the pathologic findings revealed mucinous adenocarcinoma. The cancer was located at the transverse colon and had metastases on peritoneal wall at 2nd laparotomy. Extended right hemicolectomy was performed. He underwent palliative chemotherapy. After 4 months later, hepatic metastasis and aggravated peritoneal seedings developed. He died of renal failure and pneumonia 13 months after operation. We need to have a high index of suspicion for the possibility of a malignant colorectal tumor in any childhood case with nonspecific signs and symptoms.

Difference in crude neonatal and infant mortality rates (NMR and IMR) among different countries is due to the differences in its two determinants: birth weight distribution (BWD) and birth weight-specific mortality rates (BW-SMRs). We aimed to determine impact of BWD and BW-SMRs on differences in crude NMR and IMR among Korea, Japan, and the U.S. Our study used the live birth data of the period 2009 through 2010. Crude NMR/IMR are the lowest in Japan, 1.1/2.1, compared to 1.8/3.2, in Korea, and 4.1/6.2, in the U.S., respectively. Japanese had the best BW-SMRs of all birth weight groups compared to the Koreans and the U.S. The U.S. BWD was unfavorable with very low birth weight (< 1,500 g) rate of 1.4%, compared to 0.6% in Korea, and 0.8% in Japan. If Koreans and Japanese had the same BWD as in the U.S., their crude NMR/IMR would be 3.9/6.1 for the Koreans and 1.5/2.5 for the Japanese. If both Koreans and Japanese had the same BW-SMRs as in the U.S., the crude NMR/IMR would be 2.0/3.8 for the Koreans and 2.7/5.0 for the Japanese. In conclusion, compared to the U.S., lower crude NMR or IMR in Japan is mainly attributable to its better BW-SMRs. Koreans had lower crude NMR and IMR, primarily from its favorable BWD. Comparing crude NMR or IMR among different countries should include further exploration of its two determinants, BW-SMRs reflecting medical care, and BWD reflecting socio-demographic conditions.

Despite a remarkable increase in Asian births in the U.S., studies on their birth outcomes have been lacking. We investigated outcomes of births to Asian parents and biracial Asian/White parents in the U.S. From the U.S. birth data (1992–2012), we selected singleton births to Korean, Chinese, Japanese, Filipino, Asian Indian, and Vietnamese. These births were divided into three groups; births to White mother/Asian father, Asian mother/White father, and births to the both ethnic Asian parents. We compared birth outcomes of these 18 subgroups to those of the White mother/White father group. Mean birthweights of births to the Asian parents were significantly lower, ranging 18 g to 295 g less than to the White parents. Compared to the rates of low birthweight (LBW) (4.6%) and preterm birth (PTB) (8.5%) in births to the White parents, births to Filipino parents had the highest rates of LBW (8.0%) and PTB (11.3%), respectively, and births to Korean parents had the lowest rates of both LBW (3.7%) and PTB (5.5%). This pattern of outcomes had changed little with adjustments of maternal sociodemographic and health factors. This observation was similarly noted also in births to the biracial parents, but the impact of paternal or maternal race on birth outcome was different by race/ethnicity. Compared to births to White parents, birth outcomes from the Asian parents or biracial Asian/White parents differed depending on the ethnic origin of Asian parents. The race/ethnicity was the strongest factor for this difference while other parental characteristics hardly explained this difference.

Retroperitoneal lipoma probably constitute the group of the most massive solid abdominal tumors; their etiology is unknown; their symptoms insidious; and recurrence and sarcomatous change frequent. The clinical diagnosis was made by clinical symptoms, physical findings and radiologic evaluation such as intravenous urography, ultrasonography, computed tomography, angiography and so on. Abdominal CF scan provided clinically the most useful information regarding the state of tumors and also their effect on adjacent structures and shows homogenous appearing fat tissue with a low attenuation coefficient identical to that found in the subcutaneous fat. We present a case of treatment for a huge retroperitoneal lipoma in a 46-year-old man.

OBJECTIVE: The purpose of this study was to investigate the prevalence and risk factors of ulnar neuropathy at the elbow (UNE) in a rural district in Korea. METHOD: Among the 578 residents in a rural district who participated in the health examination, 450 (116 male, 334 female) adults were randomly selected. A symptom questionnaire and electrodiagnostic studies were used to diagnose UNE. General characteristics, female-related factors, work-related factors and anthropometric measurements were compared between normal and UNE group to identify the risk factors of UNE. RESULTS: Subjects with UNE were 29 (6.4%), symptom without electrodiagnosis findings 23 (5.1%), asymptomatic subjects were 379 (84.2%). Diabetes mellitus, repetitive heavy lifting were risk factors of UNE. CONCLUSION: The prevalence of UNE was 6.4% in a rural district and these data suggest that medical conditions like diabetes mellitus and physical factors like repetitive heavy lifting are risk factors of UNE.
