Review Case Reports Multicenter Study
Clinical features of 10 patients with IgG4-related retroperitoneal fibrosis.
To elucidate the clinical characteristics of IgG4-related retroperitoneal fibrosis (RF). ⋯ IgG4-related RF has several clinical characteristic features. Our diagnostic criteria may be helpful in obtaining a correct diagnosis.

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.

Review Case Reports
Persistence of secondary restless legs syndrome in a phantom limb caused by end-stage renal disease.
Our patient had secondary restless legs syndrome (RLS) in the left lower limb caused by end-stage renal disease (ESRD). Severe RLS symptoms persisted even after amputation of the affected limb. Considering that oral administration of a dopamine receptor agonist was effective in treating the RLS in the phantom limb in this case, dysfunction of the central dopaminergic system was thought to be involved in the phantom limb-RLS mechanism. The persistence of RLS symptoms even after amputation of the affected limb suggests that the area responsible for ESRD-related RLS symptoms exists at the spinal level or in the higher central nervous system.

Review Case Reports
MELAS and reversible vasoconstriction of the major cerebral arteries.
A 26-year-old woman was admitted due to an altered mental status and generalized tonic-clonic seizures. She had experienced chronic migraine-like headaches, progressive bilateral hearing loss, a short stature and nephrotic syndrome. Laboratory data showed elevated lactate and pyruvate levels. ⋯ A genetic study revealed a mitochondrial DNA A3243G point mutation. The patient's clinical symptoms and MRI/MR angiography (MRA) findings improved within four weeks. We herein discuss the possible pathophysiology involving both stroke-like episodes and reversible vasoconstriction.

Review Case Reports
Japanese features of native valve endocarditis caused by coagulase-negative staphylococci: case reports and a literature review.
Although coagulase-negative staphylococci (CoNS) is a frequent cause of prosthetic valve endocarditis, native valve endocarditis (NVE) caused by CoNS is not commonly seen. Its high mortality is well known; however, there are no systematic reports published in Japan. We herein report the cases of two Japanese patients with CoNS NVE who were admitted to our hospital located in Tokyo and conduct literature searches on CoNS NVE in Japan from 1983 to March 2012 using PubMed and ICHUSHI WEB (Japan Medical Abstract Society). We also summarize the features of 22 Japanese patients with CoNS NVE, including our patients.
