The Relation between Hamstring Strain Injury and Physical Characteristics of Japanese Collegiate Sepak Takraw Players.

The aim of this study was to investigate the injuries in Japanese collegiate sepak takraw players. We primarily focused on hamstring strain injury (HSI), and investigated the associated physical characteristics. The study included 77 Japanese collegiate sepak takraw players who were interviewed; data were collected regarding injuries sustained by them during the game within the past year. The hip range of motion (ROM) was measured. The total number of injuries was 48 in a year. The rate of HSI was the highest (31.3%) among all the injuries. All HSIs occurred in the dominant leg because of the sunback spike. Using the Mann-Whitney U test, significant differences in age and sport-related experience were observed between the injured group and uninjured group. Upon using logistic regression analysis, the presence of a HSI was found to be associated with the sport-related experience (adjusted odds ratio [OR], 0.30; 95% confidence interval [CI], 0.12-0.77) and the hip extension ROM (adjusted OR, 0.81; 95% CI, 0.66-0.99) after adjusting for sex, sport-related experience, and the hip ROM. HSI is the most common injury in Japanese collegiate sepak takraw players. Short sport-related experience and small hip extension ROM are related with the occurrence of HSI.

Radiologic gastrostomy placement: pigtail- versus mushroom-retained catheters.

OBJECTIVE: Two different types of percutaneous fluoroscopic gastrostomy procedures were prospectively evaluated. SUBJECTS AND METHODS: Between January 1, 1998, and August 10, 1999, 127 percutaneous gastrostomy catheters were placed in 128 patients in 128 attempts. Seventy-five 12- or 14-French pigtail-retained catheters and fifty-two 20-French mushroom-retained catheters were inserted. Catheters were generally placed on the basis of operator preference except pigtail-retained tubes were preferentially placed in patients with head and neck or esophageal malignancies and mushroom-retained catheters were preferentially placed in neurologically compromised or combative patients. The technical success, procedural complications, and catheter complications were recorded. Statistical analysis was performed. RESULTS: Ninety-nine percent (127/128) of the procedures were successful, and there were no procedural complications. One catheter was not placed because the colon intervened between the abdominal wall and stomach. In patients who received pigtail-retained catheters, the major complication rate was 3% (2/75), the minor complication rate was 8% (6/75), and the tube complication rate was 36% (27/75). The following complications were seen: tube occlusion (n = 12), inadvertent catheter removal (n = 8), peristomal tube leakage (n = 7), superficial cellulitis (n = 4), aspiration pneumonia (n = 2), and T-fastener cellulitis (n = 2). In patients who received mushroom-retained catheters, the major complication rate was 0%, the minor complication rate was 2% (1/52), and the tube complication rate was 2% (1/52). Complications were superficial cellulitis (n = 1) and partial catheter fracture (n = 1). There were no significant differences in major and minor complications between procedures. Pigtail-retained catheters had a significantly higher rate of tube complications (p < 0.001) CONCLUSION: Compared with pigtail-retained catheters, mushroom-retained gastrostomy catheters are more durable and secure and are less prone to tube dysfunction. These catheters should be preferentially placed when possible.

Percutaneous biliary drainage in patients with nondilated intrahepatic bile ducts.

OBJECTIVE: We evaluated the technical success and complications of percutaneous transhepatic biliary drainage in patients with nondilated intrahepatic bile ducts. MATERIALS AND METHODS: Between January 1, 1996, and August 31, 1998, 130 percutaneous transhepatic biliary drainage procedures were performed on patients with nondilated intrahepatic bile ducts. This group comprised primarily patients who had received liver transplants or who had sustained iatrogenic bile duct injuries. Access in all procedures was performed using a one-step system consisting of a 21-gauge needle and an .018-inch guidewire. The technical success and complications of the procedures were evaluated. RESULTS: Percutaneous biliary drainage was successful in 117 (90%) of 130 attempts. In four patients, two attempts were required to place a drainage catheter. The overall complication rate was 9%. There were seven (5%) minor complications and five major complications (4%). No procedure-related deaths occurred. CONCLUSION: Percutaneous biliary drainage can be performed with a high success rate in patients with nondilated intrahepatic ducts. The incidence and types of complications in this population were similar to those reported in patients with intrahepatic ductal dilatation.

Treatment of venous outflow stenoses in thigh grafts with Wallstents.

OBJECTIVE: We studied the effectiveness of Wallstent deployment to treat elastic femoral and iliac vein stenoses in patients with lower extremity hemodialysis grafts. MATERIALS AND METHODS: Between August 31, 1992, and October 13, 1997, 44 metallic stents were deployed in 20 patients to treat stenoses exhibiting immediate, significant elastic recoil after angioplasty. Twenty-four stents were placed in the femoral and saphenous veins, and the remaining 20 stents were placed in the iliac veins. Follow-up was provided by the nephrology and surgical service at our institution and by electronic review of patients' charts. The follow-up period was from August 31, 1992, until October 1, 1998. RESULTS: Stents were successfully inserted and stenotic lesions dilated in 100% of procedures. Each patient successfully completed at least one session of dialysis after the procedure. The primary patency rate of stents was 87% 60 days after the procedure, 51% 180 days after, 39% 1 year after, and 20% 2 years after. The secondary patency rate was 95% 60 days after the procedure, 92% 180 days after, 81% 1 year after, and 62% 2 years after. Complications were limited to two graft infections that developed 5 and 7 days after stent placement. CONCLUSION: Treatment of elastic venous stenoses is effective in patients with lower extremity dialysis grafts using metallic stents. The patency rates of these devices placed in the iliac and femoral veins are comparable with those of metallic stents placed in upper extremity and central veins.

[A case of acute retinal necrosis syndrome caused by herpes simplex virus type 1].

A case of bilateral acute retinal necrosis syndrome accompanied by viral meningitis in a 46 year-old male is reported. The characteristic scattered yellowish-white retinal exudates and retinal detachment appeared in both eyes within 2 weeks, and after treatment with intravenous acyclovir and gamma-globulin, and encircling, scleral buckling, pars plana vitrectomy, 100% SF6 tamponade procedures, the retinal detachment was repaired and the yellowish-white retinal exudates disappeared. On virological examination, the complement fixation titer for herpes simplex virus (HSV) in serum increased more than eightfold in pair serum, and the quotient of antibody for HSV type 1 (HSV-1) IgG was high. HSV-1 was isolated and cultured from the subretinal fluid. From these results, it is concluded that HSV-1 infection was the cause of the meningitis and acute retinal necrosis in this case.
