To evaluate the association between vitamin D receptor (VDR) BsmI gene polymorphism and the risk of end-stage renal disease (ESRD). ⋯ VDR BsmI gene polymorphism appears to not be associated with the risk of ESRD in the overall population, Caucasians or Asians. However, more studies should be performed in the future.

A 21-year-old man was admitted to our hospital with a fever, erythema, cervical lymphadenopathy and pancytopenia. A diagnosis of Sweet's syndrome (SS) with Kikuchi's disease (KD) and hemophagocytic syndrome (HPS) was made based on the results of a bone marrow aspiration along with the results from biopsy specimens of the brachial skin and a cervical lymph node. ⋯ He successfully entered remission through treatment with prednisolone. This findings of this case indicate that when SS with KD presents as HPS, it may suggest an association with an RIG-I-related innate immunity.

A 79-year-old woman presented with unexplained hypoxia that became exacerbated by an upright posture (platypnea-orthodeoxia syndrome). A (99m)Tc-macroaggregated albumin pulmonary perfusion scan revealed a right to left shunt of 25.5% in the supine position and 32.3% in the sitting position. ⋯ A percutaneous transcatheter closure of the defect significantly improved the patient's blood oxygenation levels when she was in the upright position. An ASD should therefore be included in the differential diagnosis of platypnea-orthodeoxia syndrome, regardless of the patient's age.

Review Case Reports
Pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma with multiple thin-walled pulmonary cysts: a case report and review of the literature.
We herein report a rare case of pulmonary mucosa-associated lymphoid tissue (p-MALT) lymphoma with multiple cystic lesions. A previously healthy 58-year-old Japanese woman visited our hospital for an evaluation of abnormal chest computed tomography (CT) findings. ⋯ She has not received any chemotherapy and has been stable for two years. This case suggests that, although rare, the possibility of p-MALT lymphoma should be considered in patients with multiple cystic lung diseases.

Irritable bowel syndrome (IBS) is a common functional gastrointestinal disorder. The pathogenesis of IBS is multifactorial. The aim of this study was to investigate the prevalence of IBS using the Rome III criteria in young Japanese women and to assess the effects of mental, physical, dietary and nutritional factors on IBS. ⋯ The prevalence of IBS observed in this study was similar to that reported in previous studies conducted in Japan and other countries. Mental, physical, dietary and nutritional factors have an impact on IBS.
