Neck sprain--a major cause of disability following car accidents.

One hundred and thirty-seven patients attending hospital following road traffic accidents were contracted regarding pain in the neck between 1 and 2 years later. Eighty-five (62 per cent) stated that they had suffered pain in the neck at some time following their accident compared with 42 (30.6 per cent) who were noted to have pain in the neck when examined soon after the accident. Thirty-one patients (22.6 per cent) still felt occasional pain 1 year after the accident and 5 had continuous pain at 1 year. Pain in the neck occurred irrespective of the direction of impact but was disproportionately common in rear impact accidents. Patients wearing seat belts experienced pain more frequently than unbelted patients.

Microwave fixation: its potential for routine techniques, histochemistry, immunocytochemistry and electron microscopy.

Human tissues, both biopsy and postmortem, and tissues from rodents were fixed by microwaves at various temperatures and compared against formaldehyde-fixed material. Conventional stains, including trichromes, worked well. Red cells were lysed, but white cells were fixed, thus permitting diagnoses of various inflammatory states. Malignant cells were equally well-preserved by the two methods. Histochemical investigations of mucosubstances, lipids and various hydrolases showed no significant difference between the two techniques. Some neurological stains, however, were not as good following microwave treatment. Immunocytochemical localization of IgA, IgM and IgG showed no significant difference after microwave fixation compared to that in tissues fixed with formaldehyde. Microwave fixation did not lead to a greater tissue shrinkage than that obtained with formaldehyde fixation. Both were significantly less than that following treatment with phosphate-buffered saline alone. Electron microscopy gave results which were interpretable, but with damage resembling early postmortem change. Microwave fixation is complete in approximately 1-2 min. The mechanism of fixation appears to be due to denaturation associated with disulphide bond formation and a decrease in solubility of proteins.

Vaginitis associated with vaginal malodour.

In two general practices in Perth, Western Australia, the most common microbiological causes of vaginal discomfort in 368 patients were Candida albicans. Gardnerella (Haemophilus) vaginalis, Trichomonas vaginalis and bacteroides fragilis. Amongst patients with abnormal vaginal odour, with or without vaginitis, the most common cause of odour was G. vaginalis. The writers advocate that heavy growths of group B streptococci, Escherichia coli, and enterococci should be considered to be the possible cause of vaginal discomfort. This reinforces the need for care in collection, transportation, and microbiological examination of swabs of the female genital tract. as well as in the clinical interpretation of these reports.
