배경 : 정상인에서 특별한 외상 없이 발생하는 자발성 신파열은 매우 드문 질환이지만 혈액 투석 환자에서는 투석기간이 장기화되면서 신낭종과 신세포암의 발생빈도가 증가로 인해 정상인에 비해 높게 나타나는 것으로 보고되고 있다. 이에 유지 혈액투석을 받고 있는 말기 신부전증 환자에서 발생한 자발성 신파열의 임상적 특성을 알아보고자 하였다. 방법 : 대상 환자는 1998년 1월부터 2003년 7월까지 가톨릭의대 3개 병원에서 유지 혈액투석을 받고 있는 환자 중에서 자발성 신파열이 발생한 12명의 환자를 대상으로 신파열의 원인, 임상증세, 치료 및 경과를 후향적으로 분석하였다. 결과 : 환자의 평균나이는 54±10세 (38-72세)였고 남자 9명, 여자 3명이었다. 일차 원인 신질환으로는 상염색체 우성 다낭신증 5명, 만성 사구체신염 2명, 당뇨병 1명, 고혈압 1명, 원인미상이 3명이었다. 신파열의 주요 임상증세는 측복부 동통이 9명이었고 육안적 혈뇨가 3명이었다. 혈액투석을 시작한 후 신파열이 발생하기까지의 기간은 평균 53±36개월 (11-103개월)이었다. 상염색체 우성 다낭신증 5명을 제외한 7명의 환자 중에서 후천성 신낭종이 발견된 환자는 6명이었다. 전체 12명 중 9명에서 신절제술을 시행하였고 나머지 3명은 수혈 등의 보존적 치료만을 받았다. 수술을 받은 9명의 환자 중 2명에서 1 ㎝ 미만의 미세 신세포암이 발견되었다. 전 환자에서 사망한 예는 없었다. 결론 : 결론적으로 혈액투석 환자에서 발생한 자발성 신파열의 주요 원인은 신낭종과 신세포 암이었으며 장기 투석 환자에서 주로 발생하였다. 그러므로 장기 혈액투석 환자에서 정기적인 초음파나 전산화 단층촬영을 시행하여 자발성 신파열의 주요 원인인 신낭종과 신세포암에 대한 추적 관찰이 필요하리라 사료된다. Background : Because of high incidence of acquired renal cyst and renal malignancy, it is suggested that spontaneous renal rupture more frequently occurs in patients receiving long-term hemodialysis than general population. This study was performed to evaluate the clinical characteristics of spontaneous renal rupture in hemodialysis patients. Methods : This retrospective study enrolled 12 hemodialysis patients who developed spontaneous renal rupture. We investigated primary renal disease, duration of dialysis, clinical symptoms and signs, radiologic findings, treatment modalities, and histologic findings. Results: The mean age of the patients was 54± 10 years old and the number of male was 9. Primary renal disease consisted of autosomal dominant polycystic kidney disease (PCKD) (n=5), chronic glomerulonephritis (n=2), diabetic nephropathy (n=l), hypertensive nephropathy (n=l), unknown cause (n=3). Presenting symptoms and signs were sudden onset of flank pain in 9 patients and gross hematuria with mild flank pain in 3 patients. Mean duration from initiation of hernodialysis to development of spontaneous renal rupture was 53±36 months. Abdominal computed tomography showed subcapsular or perinephric hematoma in all patients. Of the 7 non-PCKD patients, 6 patients had multiple acquired renal cysts. Surgical exploration was undertaken in 9 patients. Pathologic examination demonstrated small sized-renal cell carcinoma in 2 of 9 patients. Three patients were only treated with conservative management including blood transfusion. All 12 patients recovered without recurrence. Conclusion : This study demonstrated that genetic or acquired renal cyst was an important cause of spontaneous renal rupture in hemodialysis patients and presenting manifestations were sudden onset of flank pain and gross hematuria.

The incidence of Tuberculosis among the patients with end-stage renal disease(ESRD) has increased up to 16 times of that in the general population. The impairment of the cellular immunity in the ESRD patients may have a role in the pathogenesis. Extrapulmonary tuberculous manifestations such as lymph node, peritoneum, and pleura involvement are more frequent in the ESRD patients than in the general population. However, there has been no case of upper gastrointestinal(UGI) bleeding as a result of a gastric tuberculosis in the ESRD patient on hemodialysis. Here we report an unusual case of a hemodialysis patient with UGI bleeding secondary to a tuberculous gastric ulcer. A 31-year-old female on hemodialysis was admitted with melena. Endoscopy revealed a benign gastric ulcer with a visible bleeding vessel at the base, located in the anterior wall of the antrum. An exploratory laparotomy showed multiple, round, small and yellow nodules on the visceral peritoneum as well as a 1-cm sized gastric ulcer. After gastric resection, a histological examination including peritoneal nodules demonstrated chronic granulomatous inflamation with caseous necrosis and giant cells. The patient has been on antituberculosis medication and followed up in the outpatient department without any event for 8 months.

The purpose of this study is to compare the maximal strength, isokinetic muscle function and anaerobic capacity according to the positions of college and professional rugby players. Subjects for this study were 54 athletes and randomly divided into 4 groups: the forwards group in college rugby players (FCRP, n=16), backs group in college rugby players (BCRP, n=10), forwards group in professional rugby players (FPRP, n=16), and backs group in professional rugby players (BPRP, n=12). Maximal strength test was consisted of squat, bench press, bilateral grip strength. Isokinetic knee and trunk muscle functions were measured by Humac Norm device, and anaerobic pedaling power was analyzed by Wingate test. Significant differences between groups were determined with one-way repeated ANOVA. As the result of this study, there was no statistically significant difference between the absolute and relative values of the squat and bilateral grip strengths, but bench press was significantly higher in FPRP and BPRP compared to other groups. Isokinetic knee and trunk extensor and flexor muscle strength showed stronger in FPRP and BPRP than those in FCRP and BCRP as well as it was the strongest in BPRP. In addition, the anaerobic pedaling power was also the highest in BPRP. Thus, our findings suggest important information that the college rugby players and forwards in professional rugby team should be given scientific training to improve their maximum strength, isokinetic strength and anaerobic power.

The purpose of this study was to compare the effect of static, dynamic and proprioceptive neuromuscular facilitation (PNF) stretching methods on balance ability and the five basic components of physical fitness in male university students. Using a randomized crossover study design, 11 male college students took part in each of 4 stretching sessions. All stretching was performed at 2-day interval to avoid contamination of the results. As the result of this study, static and dynamic balance(p<.063) as well as physical fitness including muscle endurance(p<.882), power(p<.300) and agility(p<.151) were not statistically significant among various stretching methods. However the range of motion (ROM) at left and right hip flexion(p<.040, p<.021), core muscle strength(p<.045) and flexibility(p<.037) of the lower limb was significantly higher in PNF trial compared to the non-stretching trial. Our findings suggested importance evidence that the performing PNF stretching before training or competition might help prevent injury and improve muscle strength.

The spot weldability of dissimilar metal joints between austenitic stainless steels (STS316)/IF steels and ferritic stainless steels (STS430)/IF steels was investigated. This study was aimed to determine the spot welding parameters for a dissimilar metal joint and to evaluate the dissimilar metal joint`s weldability, including its welding nugget shape, tensile-shear strength, hardness, and microstructure. The comparison of these results was described in terms of fracture behavior. Compared with the weld lobe of similar metal joints, dissimilar metal joints (STS430/IF) had reduced weld current range. However, the weld lobe of STS316/IF steel joint showed increased weld current range. This is because the dilution of chemical composition in the molten weld pool suppressed the heat input being caused by Joule heat with current flow through the samples. The microstructure of the fusion zone was fully martensite and mixture of ferrite and martensite for austenitic stainless steel/IF steel and ferritic stainless steel/IF steel combination, respectively. The experimental results showed that the shape of nugget was asymmetric, in which the fusion zone of the austenitic and ferritic stainless steel sheet was larger due to the higher bulk-resistance. The predicted microstructure by using the Schaeffler diagram was well matched with experimental results. After peel test, the fracture was initiated from heat affected zone of ferritic stainless steel sheet side, however the final fracture was propagated into the IF steel sheet side due to its lower strength.
