The gene for glycogen-storage disease type 1b maps to chromosome 11q23.

Glycogen-storage disease type 1 (GSD-1), also known as "von Gierke disease," is caused by a deficiency in microsomal glucose-6-phosphatase (G6Pase) activity. There are four distinct subgroups of this autosomal recessive disorder: 1a, 1b, 1c, and 1d. All share the same clinical manifestations, which are caused by abnormalities in the metabolism of glucose-6-phosphate (G6P). However, only GSD-1b patients suffer infectious complications, which are due to both the heritable neutropenia and the functional deficiencies of neutrophils and monocytes. Whereas G6Pase deficiency in GSD-1a patients arises from mutations in the G6Pase gene, this gene is normal in GSD-1b patients, indicating a separate locus for the disorder in the 1b subgroup. We now report the linkage of the GSD-1b locus to genetic markers spanning a 3-cM region on chromosome 11q23. Eventual molecular characterization of this disease will provide new insights into the genetic bases of G6P metabolism and neutrophil-monocyte dysfunction

Propofol for adult procedural sedation in a UK emergency department: safety profile in 1008 cases.

Concerns exist regarding the safe use of propofol by Emergency Physicians for procedural sedation. The World SIVA International Sedation Task Force has recently created an adverse event tool, in an effort to standardize reporting. We present a safety analysis of our use of propofol using this tool.This article is freely available via Open Access.
