Sex differences in the distribution of adipose tissue in the Djungarian hamster Phodopus sungorus

Female Djungarian hamsters (Phodopus sungorus) have proportionately more adipose tissue in superficial depots than males of similar age and body composition. In both sexes, the proportion in superficial depots increases with increasing fatness. This species may be useful as a model for human obesity because it becomes as obese as modern humans without genetic, surgical or dietary manipulation and the sex differences in adipose tissue distribution resemble those of humans.     

Flumazenil, a GABA antagonist, may improve features of Parkinson's disease.

Manipulation of gamma-aminobutyrate (GABA) system has been little studied in Parkinson's disease, despite the fact that GABA subserves a large part of the basal ganglia, including the outflow tracts. To test whether antagonism of GABA could improve features of PD, we administered open label intravenous flumazenil to eight practically defined off patients and assessed UPDRS scores, bilateral 1-minute hand-tapping speed, and timed gait tests. Patients demonstrated significantly greater tapping speed, which peaked 40 minutes after injection (P < 0.05). Total motor Unified Parkinson's Disease Rating Scale scores modestly improved (P < 0.05). There were no adverse events. Mechanisms by which flumazenil could improve PD are discussed.     

The impact of hospital structure and restructuring on the nursing workforce.

OBJECTIVE: Health systems throughout much of the world have been subject to 'reform' in recent years as countries have attempted to contain the rapidly rising costs of health care. Changes to hospital structures (restructuring) have been an important part of these reforms. A significant impact of current approaches to restructuring is the loss of, or changes to, nursing management roles and functions. SETTING: Australian hospitals PRIMARY ARGUMENT: Little evaluation has been undertaken to determine the impact of hospital structure and organisational restructuring on the nursing workforce. CONCLUSIONS: There is some indication that nurses have experienced a loss of key management positions, which may impact on their capacity to ensure that adequate and safe care is provided at the ward level.     

Combined percutaneous antegrade and cystoscopic retrograde approach in the treatment of distal ureteric fistulae

Purpose To determine the efficacy of a cystoscopic approach, as definitive treatment of ureteral fistulae, after failure of antegrade ureteral stent insertion.Methods Of 43 ureter fistulae encountered over 4 years, 10 postoperative and/or postradiotherapy fistulae could not be stented via an antegrade approach alone. A cystoscopic approach was used, with the antegrade approach available as back-up, if necessary.Results In two patients the ureteral orifice could not be visualized cystoscopically, thus precluding the retrograde approach. In the eight remaining patients, the retrograde approach alone never allowed successful stenting. In six patients, combined antegrade and retrograde approaches permitted stent insertions. In three of those six patients, a complex catheterization procedure was necessary. In two patients the combined approach failed altogether. Therefore, 6 of 10 patients underwent a successful stenting procedure with the combined approach; all ultimately closed the fistula.Conclusion Antegrade stent insertion remains the treatment of choice for ureteral leaks. If the antegrade approach fails, the retrograde approach alone is not likely to be successful. Instead, a combination of both approaches often does succeed.

An unusual case of bilateral auriculotemporal syndrome presenting to an allergist.

BACKGROUND: Auriculotemporal syndrome (AS) is an uncommon disorder that may present with facial erythema with chewing food. METHODS: We report a patient referred to an allergist to rule out allergy as a reason for food-associated bilateral facial flushing. She was subsequently found to have bilateral AS. RESULTS: The symptoms of AS may overlap those associated with food allergy. There are only a few published cases of bilateral AS. CONCLUSIONS: Allergists should be aware of bilateral AS and the clinical spectrum of this disorder as AS patients may be referred to allergists to rule out food allergy.
