Case of a Man with Hemichorea and Behavioral Changes: "A Red Herring".

Background: Progressive supranuclear palsy (PSP)-pallido-nigro-luysian atrophy (PNLA) is a neuropathological entity thought to be a variant of classic PSP. Clinical features and pathologic hallmarks are the same in both conditions; however, age and order of symptom onset, disease duration and prognosis, and distribution and density of pathology differentiate the 2 entities.

Objectives: This study presents a PSP-PNLA case confirmed pathologically with a clinical presentation of hemichorea/ballism, spasticity, progressive hemiparesis, and a frontal behavioral syndrome with relative cognitive sparing early in the disease course.

Prophylactic cranial irradiation: 5 years on.

With advances in cancer management, patients are living with the long-term sequelae of both cancer and its treatment. This era of cancer survivorship poses unique challenges to the interdisciplinary cancer team in terms of management and prevention of treatment-related toxicities. This paper describes the case of a 55-year-old patient with neurocognitive disturbance as a result of prophylactic cranial irradiation (PCI).

Anti-NMDA receptor encephalitis: a cause of acute psychosis and catatonia.

Anti-N-methyl-D-aspartate receptor (anti-NMDAR) encephalitis is a newly described form of encephalitis associated with prominent psychiatric symptoms at onset. Recognition of the symptom complex is the key to diagnosis. Most patients with anti-NMDAR encephalitis develop a multistage illness that progresses from initial psychiatric symptoms to memory disturbance, seizures, dyskinesia, and catatonia.

Obesity, metabolic syndrome and esophageal adenocarcinoma: epidemiology, etiology and new targets.

Background: Rates of distal and junctional adenocarcinomas are increasing in Western countries.

Methods: Systematic review of epidemiological evidence linking obesity to esophageal adenocarcinoma (EA) was performed for studies published from 2005 to 2010. The current understanding of obesity's role in the etiology and potential dysplastic progression of Barrett's esophagus (BE) to EA is reviewed.
