Comparison of post-decompressive haematuria in rapid versus gradual bladder decompression in patients with chronic urinary retention.

Background: Chronic urinary retention (CUR) is a common urological emergency. Initial management involves the drainage of the bladder by urethral catheterisation. Relief of CUR may be associated with post-decompressive haematuria.

The social determinants of health and the patient safety paradigm.

This article extends the thesis presented in the paper by Tingle, Gibson and Ferrante (2011) that the patient safety agenda needs to operate within a new paradigm. We will introduce the social determinants of health (SDH) as an emerging discourse in global public health. The SDH advocate social and health equity among nations and individuals, and within countries and communities.

An outbreak of Streptococcus pyogenes infection associated with calcium oxalate urolithiasis in guinea pigs (Cavia porcellus).

An outbreak of Streptococcus pyogenes infection occurred in a colony of 800 Dunkin-Hartley guinea pigs resulting in 364 (46%) deaths involving breeders, sucklings, weaners, but mainly adults used as a source of blood meals for haematophagus flies (Glossina palpalis). Clinical signs included bleeding from the nose, mouth and vagina before death. Necropsy revealed pneumonia with consolidation of one or both lungs, haemopericardium and haemothorax.

Uterine involvement in guineapig salmonellosis.

Of 334 mature breeding guineapigs, 53 (15.9%) died in a disease outbreak involving Salmonella typhimurium serotypes 1, 4, 5 and 12 : i : 1,2. The uterus was consistently involved.

Double intussusception fatally complicated by clostridial infection in a dog (a case report).

A 10-month-old Alsation dog with history of anorexia, diarrhoea, dehydration and vomition developed a double intussusception which affected the distal jejunum and proximal ileum. Necropsy revealed the intussusception to be swollen and congested with fibrinous adhesions between the intussusceptum and intussuscepiens. Two pieces of bone believed to be the inciting cause were found within the intussusceptum.
