Optic pathway glioma and the sex association in neurofibromatosis type 1: a single-center study.

Background: Low-grade optic pathway glioma (OPG) develops in 15-20% of children with neurofibromatosis type 1 (NF1). OPGs are symptomatic in 30-50% and one-third of these require treatment. A few studies have suggested female sex as a risk factor for visual impairment associated with NF1-OPG.

Impact of diabetes and poor glycaemic control on risk of bacteraemia with haemolytic streptococci groups A, B, and G.

Background: Diabetes has been associated with bacteraemia due to haemolytic streptococci but epidemiological evidence is limited.

Methods: We conducted a 15-year population-based case-control study of all adults with first-time bacteraemia with groups A, B, and G haemolytic streptococci and matched population controls. The study setting was Northern Denmark between 1992 and 2006.
