Background and Aim: Functional dyspepsia (FD) is a common condition seen in primary gastroenterology practice. The present study was conducted to compare the clinical effectiveness of mosapride and teprenone in patients with FD. Methods: Prospective clinical comparative study with random allocation of open labeled medications was performed as a multicenter trial in Japan. 1042 patients presenting symptoms of FD, either with gastric stasis (GSS) and/or epigastric pain (EPS), were enrolled. After initial endoscopic evaluation, medication either with mosapride 5mg tid or teprenone 50mg tid was started. Severity and frequency of GSS and EPS, health-related quality of life (HR-QOL) by the SF-36 Japanese version, and patients' compliance to medication was evaluated. Results: Organic lesions were found in 90 patients (9%) in the 1027 patients examined by endoscopy. Among those without any specific lesions detected by endoscopy, gastrointestinal symptoms were resolved within one week after the endoscopy in 264 (28%) patients before initiating medication. 618 patients who remained symptomatic were randomized to medication either with mosapride (n=311) or teprenone (n=307). Two-week treatment with mosapride significantly improved GSS and EPS, while teprenone tended to improve only GSS. Mosapride also improved HR-QOL. 91% of patients treated with mosapride favored their medication, while only 52% of patients treated with teprenone favored their medication. Conclusions: Endoscopic evaluation at patients' presentation was effective to find active lesions and to improve FD symptoms. Mosapride was more favorably accepted than teprenone by the patients with sufficient safety and efficacy. © 2011 Journal of Gastroenterology and Hepatology Foundation and Blackwell Publishing Asia Pty Ltd.

Left ventricular assist devices (LVADs) greatly support heart recovery, but recurrent heart failure after LVAD removal limits their use as 'a bridge to recovery'. The combination of LVADs and cell transplantation (CTx) is expected to be effective to improve the success rate of LVAD removal. We investigated the feasibility of combined CTx therapy and LVAD support with a new heterotopic rat heart-lung transplantation model that could simulate LVAD support and LVAD removal. The heart and both lungs of a rat were heterotopically transplanted, and the heart was kept unloaded for two weeks. The heart was then reloaded for two weeks (LVAD group). Syngenic smooth muscle cells were transplanted into the hearts that had been unloaded for a week, and the hearts were kept unloaded for another week and then reloaded (CT-LVAD group). In the unloaded state, CTx could reduce the left ventricle (LV) volume more effectively than LVAD therapy alone (P<0.01) and maintain the LV volume even after the hearts were reloaded (P≤0.01). The results suggest that CTx with LVAD support can prevent recurrent LV dilation after LVAD removal and improve the success rate of LVAD removal. © 2011 Published by European Association for Cardio-Thoracic Surgery.

We describe a rare case of lumbar spinal stenosis due to a large calcified mass in the ligamentum flavum. This patient presented with a 12-month history of severe right leg pain and intermittent claudication. A computed tomography scan was performed, revealing a large calcified mass on the ligamentum flavum at the right-hand side of the lumbar spinal canal. We performed a laminotomy at the L4/5 level with resection of the calcified mass from the ligamentum flavum. The findings of various analyses suggested that the calcified mass consisted mostly of Ca3(PO4)2 and calcium phosphate intermixed with protein and water. The calcified mass in the ligamentum flavum was causing lumbar spinal stenosis. Surgical decompression by resection of the mass was effective in this patient. The calcified material was composed mainly of elements derived from calcium phosphate. Degenerative changes in the ligamentum flavum of the lumbar spine may have been involved in the production of this calcified mass. © 2013 by Korean Society of Spine Surgery. Source

The neoplasms of the ear are rare and may be similar to the inflammatory lesions and normal variants. To diagnose them precisely, we need to familiar with those findings. As each disease has characteristic shape, location and density/intensity, we can differentiate many of them radiologically. In some cases, differentiation is difficult, which have to rely on the pathological diagnosis. Furthermore, the decision of bounds of tumor extension may be a determining factor of the operation procedure, which demand the radiological diagnosis. Source

We present a rare case with pituitary apoplexy after three-vessel off-pump coronary artery bypass grafting (OPCAB). The patient exhibited right third cranial nerve palsy; ptosis of the right eye with completely dilated pupils and a loss of reflex to light after the effects of anesthesia completely subsided. The patient underwent endonasal transsphenoidal resection of the pituitary gland 14 days after the OPCAB, and the symptoms completely disappeared 40 days after the resection. OPCAB is recommended for patients with known pituitary tumor who require coronary artery bypass grafting, but OPCAB also has a risk of pituitary apoplexy. The present case report is the first to describe pituitary apoplexy after OPCAB. Pituitary apoplexy is a very rare complication after cardiac surgery, but cardiac surgeons should know the disease and quickly diagnose it to avoid severe brain injury. © 2011 Published by European Association for Cardio-Thoracic Surgery.
