Neurologic eye signs following motorcycle accidents

A review of 96 consecutive patients who suffered neuro-ophthalmologic injuries in motorcycle accidents revealed a wide range of findings. These findings were similar to signs associated with other forms of closed-head trauma, aside from a higher incidence of trochlear nerve palsies.     

Surgical treatment of urinary stress incontinence.

This article reviews traditional vaginal and suprapubic procedures as well as more recent advances such as urethral bulking agents and artificial sphincters. It illustrates how the chosen operation must be tailored to the individual patient and how the surgeon treating urinary incontinence requires a variety of procedures in his repertoire.     

Effect of growth hormone on human alveolar macrophage oxidative metabolism

BACKGROUND: Growth hormone (GH) has diverse immunological actions and has been shown to augment oxidative metabolism in rat peritoneal and porcine alveolar macrophages and both human and animal neutrophils. A study was performed to determine the effects of GH on human alveolar macrophages in vitro. METHODS: Macrophages were harvested from 10 patients undergoing bronchoalveolar lavage and incubated with 0, 10 and 100 nmol/ml GH for four hours. Oxidative metabolism was assessed by means of a fluorescent assay using FMLP and E coli as stimulants. Fluorescence was measured using flow cytometry. RESULTS: No difference in basal or stimulated oxidative metabolism was found between the GH and control groups. CONCLUSIONS: GH does not have a direct stimulatory action on human alveolar macrophages in vitro. However, this does not exclude an indirect effect in vivo. The results contrast with previous studies on animal alveolar macrophages.




     

The microbial flora of in-use blood pressure cuffs

The capacity of blood pressure cuffs to act as vehicles of hospital infection has been recognised. We describe the microbial flora of in-use DINAMAP blood pressure cuffs used in the operating theatres and one recovery room in a teaching hospital. Our results show significant microbial contamination of in-use blood pressure cuffs.     

Percutaneous balloon pericardiotomy in the management of recurrent malignant pericardial effusions

Two patients with recurrent symptomatic pericardial effusions secondary to malignant disease were successfully treated by percutaneous balloon pericardiotomy. Open surgery was avoided and the procedure was completed under local anaesthesia in less than 40 minutes. The first patient was free of recurrence at nine months but pericardial effusion recurred at two months in the second patient.Percutaneous balloon pericardiotomy offers a potentially important new means of relieving recurrent tamponade and substantially reduces trauma to the patient.
