PURPOSE: This study was performed to analyze the clinical characteristics of urologic patients who visited emergency center and provide a fundamental data for further study, and to add some help in the management of the patients. Materials and Methods: Among the total 99,935 patients who visited the emergency center from July 1, 1993 to June 30, 1995, the clinical data of 3,063 urologic patients was reviewed retrospectively. RESULTS: The most common group of age was 4th decade, and male predominated over female by 2.6 : 1. The peak time of patient's entrance to emergency center was between 20 : 00 and 24 : 00 (24.4%) and second peak was 00 : 00 and 04 : 00 (18.5%). Flank pain (57.5%) was the most common symptom and urinary retention (10.3%), gross hematuria (9.7%), irritative voiding symptoms (7.5%) followed that. The common diseases or injury were urinary stone (56.4%) and benign prostatic hyperplasia (8.0%), renal injury (4.0%), acute cystitis (3.7%) respectively. The admission rate was 23.3% and the ratio between urologic department and other departments was 4 : 1. Trauma was occupied 12.5% in all urologic patients and common disease or injuries that needed emergent operation were bladder rupture (23.5%), testicular torsion (18.5%), and renal trauma (16.0%). 7 patients with multiple injury were expired due to 1 urologic cause (renal trauma) and 6 non-urologic causes. CONCLUSIONS: The most common cause that brings the urologic patients to the emergency center is flank pain associated with urinary stone and the factors related to increased occurrence are male, age of 4th decades and midnight.

Emphysematous urinary tract infection is a rare, life-threatening necrotizing infection characterized by gas generation, and usually occurs in patients with diabetes and/or urinary tract obstruction. We herein report a unique case of emphysematous renal infection occurred in. an old diabetic man with renal cell carcinoma. This case suggests that renal cell carcinoma should be also considered a rare cause of emphysematous renal infection showing mass contour.

PURPOSE: To evaluate the usefulness and safety of unified technique of vascular control before renal exposure in reconstructive surgery of renal trauma. MATERIALS AND METHODS: From July 1995 to June 1997, 10 patients with major renal trauma who operated by unified approach technique were included in this study. Blunt trauma was the mechanism of injury in 8 patients and 2 were resulted from penetrating(stab) injury. Of the injuries 2 were grade 3, 7 grade 4, 1 grade 5. RESULTS: Of the 10 patients, 8(80%) were performed kidney preserving surgery and 2(20%) resulted in nephrectomy. Partial nephrectomy was underwent in 6 patients(with vascular repair in 2 cases) and renorrhaphy in 2 patients. Pedicle flap of omentum was used mainly and polyglycolic acid mesh also used in 2 cases as coverage material of parenchymal defect. Complications occurred in 2 cases(20%) but none resulted in renal loss with the mean followup of 10 months(1 to 15 months). CONCLUSIONS: Unified approach technique of vascular control before renal exposure seems to be a safe and effective method for reconstructive surgery in renal trauma. To confirm this result, studies with more cases and longer followup are needed.

The main trend moves towards early excision and skin grafting as treatment for the deep second degree burns and the third degree burns. The ability to excision & skin grafting. This study prospectively evaluated the ability of laser doppler flow measurements obtained within 72 hours after burn injury to predict the depth of burn wounds. A Periflux system 4001 laser doppler flowmetry had been used to measure cutaneous microflow circulation of 100 selected points of burn wounds in 44 admitted patients from March 1993 to February 1994. The mean value of superficial second degree burn checked by laser doppler was 194.6 perfusion unit(PU). The deep second degree burn was 59.7 PU and third degree burn was 5.1 PU. The blood flow of more than 100 PU reliably predicted the superficial second degree burn with 90.2 percents accuracy. The blood flow between 100 PU and 10 PU predict the deep second degree dermal burn with 96.2 percents accuracy. That of less than 10 PU predict the third degree burn with 100 percents accuracy. There was also a significant correlation between initial flow measurements and the depth of burn wounds. We conclude that laser doppler flow measurements performed early after burn injury are useful in predicting the depth of burn wounds. The laser doppler flowmetry has the advantage of being easy to use, noninvasive, provide immediate result for early determination of burn depth. The laser doppler flowmetry is useful in selecting patients for early excision and grafting of burn wounds.

V. parahaemolyticus was isolated from blood culture of a 34-year old female patient with HCV viral hepatitis and liver cirrhosis. V. parahaemolyticus is one of the frequent causative agents of gastrointestinal infection, but rarely causes septicemia. This case is thought to be the 3rd report of V. parahaemolyticus septicemia in Korea.

The horse stable hand workers are one of the most important occupations in horse-racing industry. However, suicide problem of the horse stable hand workers in Korea has raised the necessity of new study on how these workers experience mental health problems such as occupational stress and depression in organizational situation. Therefore, this study investigated the occupational stress and depression level of the horse stable hand workers and identified the structural relationship in the horse-racing industry through a detailed interview. A total of 207 horse stable hand workers participated in this study, and occupational stress and depression level were surveyed using the Korean Occupational Stress Scale (KOSS) and Korean version of the Center for Epidemiologic Studies-Depression Scale (CES-D). The results of this study showed that the occupational stress level of horse stable hand workers was higher than the median of Korean population. The significant difference in occupational stress among the detail job grade was also identified. In addition, 34% of the horse stable hand workers showed high risk of depression, and job demand, organizational system, and inappropriate compensation as the subfactors of occupational stress were showed to mainly affect depression. Although there are some limitations according to the field survey, this study also has significant meaning in that it identifies the relationship between the occupational characteristics of the horse stable hand workers and the mental health. It will be necessary to study the diverse organizational situation and individual mental health for new occupations.

Purpose:
Gonadotropin-releasing hormone agonist (GnRHa) is a safe and effective therapy used to treat central precocious puberty (CPP). Although most studies have reported no significant difference in body mass index (BMI) in girls during and after GnRHa therapy, few studies have investigated changes in BMI in boys with CPP. This study evaluated the effects of GnRHa therapy on BMI in boys with CPP.
Methods:
This study included 75 boys with CPP at Ajou University Hospital between January 1, 2007 and December 31, 2016, who treated with leuprorelin acetate or triptorelin acetate every 4 weeks for at least 2 years. The subjects were divided into 3 groups according to BMI: normal weight, overweight, and obese. We analyzed the BMI standard deviation score (SDS) in each group before therapy and after 1 year and 2 years of therapy.
Results:
Of the 75 boys, 37 were in the normal weight group, 21 were in the overweight group, and 17 were in the obese group. Magnetic resonance imaging that was performed before treatment showed abnormal findings in 9 boys. The mean BMI SDS for all participants at initiation was 1.0±0.8, and that in the normal weight, overweight, and obese groups was 0.3±0.4, 1.3±0.1, and 1.9±0.3, respectively. There were no significant differences in BMI SDS in any group after 1 or 2 years of treatment.
Conclusion
The BMI SDS in boys with CPP did not significantly change over 2 years of GnRHa therapy.

The objective of the present study was to determine the relationship between serum uric acid (SUA) level and the presence of nonalcoholic fatty liver disease (NAFLD). We analyzed data of 9,019 Koreans who visited a health check up center. The SUA levels of all of these subjects were within the normal range. The participants were divided into 4 groups according to the quartiles of the SUA levels for both sexes. Hepatic steatosis was diagnosed on the basis of ultrasonographic findings. Multivariate logistic regression modeling was performed across the SUA quartiles. The presence of NAFLD and metabolic abnormalities were found significantly in subjects with high-normal SUA levels. After adjustment for age, metabolic components, and the liver-function test, the adjusted odds ratio (OR, 95% CIs) for the presence of NAFLD in the subjects with the highest SUA level was 1.46 (1.17-1.82) for men and 2.13 (1.42-3.18) for women, as compared to the subjects with the lowest SUA level. Our results suggest that increased SUA concentrations, even within the normal range, are independently associated with the presence of NAFLD.
