A study was performed to evaluate the physical exercise characteristics of 29 Japanese elite judo athletes by treadmill exercise test. Functional aerobic impairment (FAI), heart rate impairment (HRI) and peripheral circulatory impairment (PCI) in the judo athletes were not significantly different from those of normal sedentary subjects. However, myocardial aerobic impairment (MAI) was lower than in normal sedentary subjects. %VO2max at the anaerobic threshold (AT) was 57.5±3.3% in male, and 57.0±4.3% in female judo athletes. %HRmax at AT was 72.4±3.8% in males, and 75.2±5.3% in females.
These findings suggest that functional aerobic capacity and peripheral circulatory function in Japanese elite judo athletes are not significantly different from those of normal sedentary subjects, but that judo athletes have high left ventricular function.
The blood biochemical profile and urinalysis date revealed that values of muscle injury enzymes, plasma uric acid and cholesterol were increased with relatively high freqency in elite judo athletes. Similar data were also obtained in individuals with suspected diabetic nephropathy and rhabdomyolysis.

Multiple endocrine neoplasia type 1 (MEN1) is an inherited autosomal dominant disease presenting with pancreatic neuroendocrine tumors (pNETs), parathyroid tumors, or pituitary tumors. Using the PubMed database, we reviewed the literature on information regarding the proper diagnosis and treatment of MEN1-associated pNET. Many cases of MEN1-associated pNET are functioning pNETs. Gastrinomas and insulinomas tend to occur frequently in the duodenum and pancreas, respectively. In addition to diagnostic imaging, the selective arterial secretagogue injection test (SASI test) is useful for localizing functioning pNET. The standard treatment is surgical resection. However, in the case of a functioning pNET, the tumor should first be accurately located using the SASI test before an appropriate surgical method is selected. In cases of a MEN1-associated non-functioning pNET that exceeds 2 cm in diameter, the incidence of distant metastasis is significantly increased, and surgery is recommended. In cases of unresectable pNET, a somatostatin analog has been shown to demonstrate antitumor effects and is considered to be a promising treatment. In addition, molecular-targeted drugs have recently been found to be effective in phase III clinical trials.

BACKGROUND/AIMS: The ability of endoscopic submucosal dissection (ESD) to resect large early gastric cancers (EGCs) results in the need to treat large artificial gastric ulcers. This study assessed whether the combination therapy of rebamipide plus a proton pump inhibitor (PPI) offered benefits over PPI monotherapy. METHODS: In this prospective, randomized, multicenter, open-label, and comparative study, patients who had undergone ESD for EGC or gastric adenoma were randomized into groups receiving either rabeprazole monotherapy (10 mg/day, n=64) or a combination of rabeprazole plus rebamipide (300 mg/day, n=66). The Scar stage (S stage) ratio after treatment was compared, and factors independently associated with ulcer healing were identified by using multivariate analyses. RESULTS: The S stage rates at 4 and 8 weeks were similar in the two groups, even in the subgroups of patients with large amounts of tissue resected and regardless of CYP2C19 genotype. Independent factors for ulcer healing were circumferential location of the tumor and resected tissue size; the type of treatment did not affect ulcer healing. CONCLUSIONS: Combination therapy with rebamipide and PPI had limited benefits compared with PPI monotherapy in the treatment of post-ESD gastric ulcer (UMIN Clinical Trials Registry, UMIN000007435).

BACKGROUND/AIMS: Colonic diverticular bleeding can stop spontaneously or be stopped by endoscopic hemostasis. We analyzed the clinical and colonoscopic features of patients with colonic diverticular bleeding to establish the predictive factors for rebleeding. METHODS: A total of 111 patients (median age, 72 years) with colonic diverticular bleeding in Aso Iizuka Hospital between April 2007 and July 2010 were enrolled. Age, sex, body mass index (BMI), comorbidity, medication, location of bleeding, colonoscopic findings and hemostatic methods were analyzed retrospectively from the hospital records. RESULTS: The most common sites of bleeding were the ascending (39.6%) and sigmoid (29.7%) colon. Overt rebleeding occurred in 30 patients (27.0%). Spontaneous hemostasis was seen in 81 patients (73.0%), and endoscopic hemostatic treatment was performed in 30 patients. The BMI in the patients with colonic diverticular rebleeding was significantly higher than in patients without rebleeding. Colonoscopic findings of actively bleeding or nonbleeding visible vessels in the responsible diverticula were more frequent in the group with rebleeding. CONCLUSIONS: A higher BMI and colonoscopic findings of actively bleeding or nonbleeding visible vessels can be used as predictive factors for colonic diverticular rebleeding. Patients with such findings should be carefully followed up after hemostasis of the initial colonic diverticular bleeding.

OBJECTIVETo characterize the symptoms of neurogenic intrapelvic syndrome and the pathogenic mechanisms.
METHODSA total of 537 patients with neurogenic intrapelvic syndrome were treated in the Takano Hospital between 2001 and 2005. Clinical data were analyzed retrospectively.
RESULTSThe mean age was 58.5 years old. There were 205 males and 332 females. There were 80 patients(14.9%) who presented with only one symptom with anorectal pain being the most common one (43.8%, 35/80). One hundred and fifty-six(29.1%) patients had two symptoms with anorectal pain and difficult evacuation being the most common combination (26.3%, 41/156). There were 144 patients (26.8%) complained of 3 symptoms and the most common combination was anorectal pain, difficult evacuation, and abdominal discomfort (30.0%, 43/144). A combination of 4 symptoms was reported in 105 patients(19.6%) with the combination of anorectal pain, incontinence, abdominal discomfort, and lumbar discomfort being the most often(65.7%, 69/105). In addition, there were 52 patients(9.7%) who had above 5 symptoms simultaneously. The frequencies of the 5 symptoms were 73.6% for anorectal pain, 27.9% for incontinence, 69.6% for difficult evacuation, 55.3% for abdominal discomfort, and 53.6% for lumbar discomfort.
CONCLUSIONSSymptomatology of neurogenic intrapelvic syndrome is complicated. The pathogenic mechanism may be related to concurrent dysfunction of sacral nerve and pelvic splanchnic nerve.

Objectives:
The relationship between weight-related load and bone mineral density (BMD)/bone microstructure under normal load conditions using high-resolution peripheral quantitative computed tomography (HR-pQCT) remains unconfirmed. The study aims to investigate the differences in effect of body mass index (BMI) on BMD/bone microstructure of loaded and unloaded bones, respectively, in Japanese postmenopausal women.
Methods:
Fifty-seven postmenopausal women underwent HR-pQCT on the tibia and radius. Correlation analysis, principal component (PC) analysis, and hierarchical multiple regression were performed to examine the relationship between BMI and HR-pQCT parameters.
Results:
Several microstructural parameters of the tibia and radius correlated with BMI through a simple correlation analysis, and these relationships remained unchanged even with an age-adjusted partial correlation analysis. PC analysis was conducted using seven bone microstructure parameters. The first PC (PC1) reflected all parameters of trabecular and cortical bone microstructures, except for cortical porosity, whereas the second PC (PC2) reflected only cortical bone microstructure. Hierarchical multiple regression analysis indicated that BMI was more strongly related to BMD/bone microstructure in the tibia than in the radius. Furthermore, BMI was associated with trabecular/cortical BMD, and PC1 (not PC2) of the tibia and radius. Thus, BMI was strongly related to the trabecular bone microstructure rather than the cortical bone microstructure.
Conclusions
Our data confirmed that BMI is associated with volumetric BMD and trabecular bone microstructure parameters in the tibia and radius. However, although BMI may be more related to HRpQCT parameters in the tibia than in the radius, the magnitude of association is modest.
