Coronary subclavian steal syndrome is an unusual cause of myocardial ischemia, secondary to a reversed blood flow in patients with patent internal thoracic artery coronary bypass grafts. The causes of coronary subclavian steal are either ipsilateral subclavian artery stenosis or upper extremity arteriovenous hemodialysis fistula formation or both. This report involves a 68-year-old woman with left vertebral artery occlusion who developed severe coronary steal in the absence of vertebral subclavian steal due to left subclavian artery stenosis and an arteriovenous hemodialysis graft.

We herein report the case of a 17-year-old man who developed an increased plasma creatinine level (11.1 mg/dL) and oliguria with massive proteinuria (27.3 g/day) four weeks after an abraded wound to his right knee. The histology of the renal biopsy specimens showed diffuse endocapillary proliferative glomerulonephritis with the deposition of nephritis-associated plasmin receptor in the glomerulus. A case of acute kidney injury due to nephrotic syndrome caused by acute post-streptococcal glomerulonephritis was diagnosed. His renal function and proteinuria were improved with supportive care, including hemodialysis, without the administration of immunosuppressive agents.

DRESS (drug rash with eosinophilia and systemic symptoms) syndrome is a severe reaction triggered by drugs that manifests as pyrexia and eosinophilia with involvement of the skin and internal organs. We herein describe the case of a patient who developed hyperuricemia after receiving treatment for tuberculosis, then took allpurinol and developed DRESS syndrome with a contextual coma and right hemisyndrome. ⋯ The cerebral vasculitis responded to treatment, showing clinical and instrumental remission. In cases such as this, allergic cerebral vasculitis should be considered in the differential diagnosis because it can be treated if recognized early, thus leading to remission without the development of any sequelae.

We herein present the case of a 69-year-old Japanese man who had unprotected sexual contact with a local commercial sex worker in an East Asian country and was diagnosed as having disseminated gonococcal infection (DGI). The organism was confirmed to be Neisseria gonorrhoeae based on 16S rRNA sequencing and positive results for the cppB gene. ⋯ DGI potentially causes many complications, and the pathogen has recently been reported to be resistant to various antibiotics. Physicians must therefore pay more attention to the possible occurrence of DGI in various clinical settings.

Autosomal recessive cerebellar ataxias and autosomal recessive hereditary spastic paraplegias are clinically and genetically heterogeneous disorders with diverse neurological and non-neurological features. We herein describe a Japanese patient with a slowly progressive form of ataxia and spastic paraplegia. ⋯ This is the first report of an SPG7 mutation in the Japanese population. For disorders previously undetected in a particular population, or unrecognized/atypical phenotypes, exome sequencing may facilitate molecular diagnosis.
