Hemarthrosis occurring after arthroscopic surgery for lesions of the shoulder joint is a very rare complication that can develop due to an injury to the blood vessels when an anterior portal is formed. This is a complication that rarely develops in patients who are taking antithrombotic drugs or who do not have associated diseases, such as thrombocytopenia. We report a case of hemarthrosis that occurred after performing arthroscopic surgery to repair a rotator cuff tear in a patient with a stenosis in an arteriovenous fistula for hemodialysis in the ipsilateral upper arm.

The quality factors (kQ,Q0) were evaluated by appling the results recently studied for the effect of central electrode in TRS-398 protocol. The PTW-31010 and IBA-CC13 chambers were used in this study. The quality factors were calculated as a function of beam quality for high energy electron and photon beams and compared with data currently used in TRS-398 protocol. In the PTW-31010 chamber using aluminium electrode, appling the new central electrode collections, the quality factors were 0.4% and 0.9% higher than current TRS-398 data for high energy photon and electron beams respectively. In the IBA-CC13 chamber using C-552 electrode, there are no variations in quality factors compared to TRS-398 data currently used.

Urological complications are not uncommon in Crohn's disease (CD). The most common manifestations are renal stones, enterovesical fistulas, and ureteral obstruction, but renal parenchymal disease has rarely been reported. IgA nephropathy, the most common form of primary glomerulonephritis, is usually isolated, but can be sometimes associated with chronic extrarenal disorders such as inflammatory bowel disease. We describe a case of 36 year-old man with CD associated with IgA nephropathy. He was diagnosed as CD 6 years ago and at that time, isolated proteinuria was observed. He presented recurrent proteinuria and elevation of creatinine level while he had been managed well with mesalamine and azathioprine. The renal biopsy was performed and IgA nephropathy (type IV) was diagnosed. Strict blood pressure control with angiotensin converting enzyme inhibitor and calcium channel blocker resulted in clinical improvement and normalization of serum creatinine level.

For the purpose of quality assurance (QA) of the blood irradiator, QA programs for daily, monthly, and yearly were developed. For daily tests, simple items for basically operating the machine are recommended. For monthly and yearly tests, the measurement of dose to assure the dose delivery system are performed by a dosimetry devices (Glass dosimeter jig) developed in this study. The QA program is practical for clinical environment.

PURPOSE: The purpose of this study was to analyze the characteristics and severity of wrist injuries in snowboarding. METHODS: December 2005 to February 2008, Snowboarders who experienced wrist injures were included in this study. On the basis of the medical records and radiographic evaluation, the severity of distal radius fracture was classified according to the Arbeitsgemeinschaft fur Osteosynthesefragen/Association for the Study of Internal Fixation (AO/ASIF) classification. RESULTS: Most of the injured snowboarders were a either of the beginner (35 cases, 46.1%) or the intermediate (27 cases, 35.5%) level. The most common cause of injury in snowboarding was a slip down (60 cases, 78.9%). Comminuted and articular fractures classified as AO types A3, B, and C, which required surgical reduction, made up 42.3% of the distal radial fractures in snowboarders. When we analyzed the differences in severity between the educated and the non-educated groups, an A2 type injury in the AO classification was the most common type of injury in the educated group (20 cases, 38.5%), it means less severe fractures ocurred in the educated group (p=0.045). The most frequent injury mechanism of fractures was slip down (48 cases, 63.2%), and a slip down backwards was the dominant type of slip down (36 cases, 75.0%) (p=0.031). CONCLUSION: Among the snowboarders in this study who suffered self-down injury to the wrist, more fractures were associated with a backwards slip down than with a forward slip down due to over extension. For educated snowboarders the severity of fracture was lower than it was for uneducated snowboarders.

BACKGROUND: Atrial fibrillation (AF) is the most common cause of embolic cerebral infarction. This study was performed to determine new risk factors and the mechanism underlying thromboembolism (TE) in patients with AF. METHODS: 192 patients (M:F=137:55, 61+/-11 years) with AF were randomly selected and divided into a TE (n=95) and non-TE group (n=97). Another 71 patients with AF (M:F=38:33, 55+/-14) were studied for endothelial function by measuring the level of von Willebrand factor (vWF; factor 8 related antigen), inflammation by WBC, ESR, and high sensitive CRP and coagulation system by fibrinogen, fibrinogen degradation product and fibrin d-dimer; the results were compared with 25 patients with normal sinus rhythm. RESULTS: The TE group was older than non-TE group. Hypertension (HTN), diabetes mellitus (DM), hypercholesterolemia, smoking and fine AF (AF wave amplitude <1 mm) were more frequent in the TE group. Mitral valvular disease, an ejection fraction <40% and dilated cardiomyopathy were more frequent in the TE group and the left atrial (LA) dimension was greater in the TE group. The use of anticoagulants, an angiotensin-II receptor blocker and statins were less frequently observed in the TE group. The vWF-factor 8 related antigen was higher in patients with advanced age, LV dysfunction, HTN, DM, mitral stenosis and positively correlated with age, LA dimension, LV end-diastolic and end-systolic dimension, ejection fraction, NYHA class and AF duration. The fibrinogen level was positively correlated with age, NYHA class, LA dimension and d-dimer with NYHA class. Markers for inflammation or coagulation were not significantly different in the atrial fibrillation and the sinus rhythm group. CONCLUSIONS: No use of an angiotensin-II receptor blocker or statin and fine AF may be new risk factors for TE in patients with AF. The TE risk factors are thought to increase TE by impairing endothelial function.

BACKGROUND/AIMS: Antispasmodic agents have been used in the management of irritable bowel syndrome. However, systematic reviews have come to different conclusions about the efficacy in irritable bowel syndrome. Fenoverine acts as a synchronizer of smooth muscle in modulating the intracellular influx of calcium. We compared fenoverine with trimebutine for the treatment of patients with IBS. METHODS: A multicenter, randomized, double-blind, non-inferiority clinical study was conducted to compared fenoverine with trimebutine. Subjects were randomized to receive either fenoverine (100 mg three times a day) or trimebutine (150 mg three times a day) for 8 weeks. A total of 197 patients were analyzed by the intention-to-treat approach. The primary endpoint was the proportion of patients who had 30% reduction in abdominal pain or discomfort measured by bowel symptom scale (BSS) score at week 8 compared to the baseline. The secondary endpoints were changes of abdominal bloating, diarrhea, constipation, overall and total scores of BSS, and overall satisfaction. RESULTS: At week 8, fenoverine was shown to be non-inferior to trimebutine (treatment difference, 1.76%; 90% CI, -10.30-13.82; p=0.81); 69.23% (54 of 78 patients) of patients taking fenoverine and 67.47% (56 of 83 patients) of patients taking trimebutine showed 30% reduction in abdominal pain or discomfort compared to the baseline. There results of the secondary endpoints were also comparable between the fenoverine group and the trimebutine group. CONCLUSIONS: Fenoverine is non-inferior to trimebutine for treating IBS in terms of both efficacy and tolerability.
