Hemiplegia due to hypoglycaemia followed by haemicorea after correction of glycaemic values.

A 69-year-old man suffered from hemiplegia of the left limb due to hypoglycaemia. After 3 h of oral supplementation with sugar water, the patient recovered from hemiplegia but then presented symptoms of haemichorea. To our knowledge, a case of abnormal glucose metabolism complicated with two types of motor disturbance has not been reported previously.

COMT Val158Met polymorphism and Parkinson's disease risk: a pooled analysis in different populations.

Objective: Many studies have analyzed the association between the catechol-O-methyltransferase (COMT) Val158Met polymorphism and Parkinson's disease (PD), which yield inconsistent results. This meta-analysis was designed to determine the possible association between the COMT Val158Met polymorphism and the risk of PD in different populations.

Methods: The PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure and Chinese Biology Medicine databases were used for literature searching up to May 2018.
