Hypertension detected in young black women by routine screening in a family planning clinics.

The prevalence of hypertension, defined as a diastolic blood pressure over 100 mmHg, among young Black women who attended a family planning clinic in Johannesburg, was 2,85%, while in those over 35 years of age it was 8,5%. There was no correlation between hypertension and urbanisation, occupation or urinary sodium output. Within 6 months of diagnoisis, 84% of the women with hypertension had defaulted from the treatment clinic. Family planning clinics can economically screen patients for hypertension, but in this community a separate screening programme would not succeed until patient compliance has improved.

A study of the perineurium in peripheral nerve pathology.

The response of the perineurium to the following experimental systems was investigated by light and electron microscopy: nerve crush, cold lesion and microinjection of (a) histamine liberator, (b) potassium cyanide, (c) lysophosphatidyl choline (LPC). Where myelin breakdown occurred, lipid globules were seen within Schwann cells, macrophages and also perineurial cells. Where increased vascular permeability occurred, proteinaceous material leaked from endoneurial vessels into the endoneurial space and later appeared between perineurial laminae. It is suggested that the normal homeostatic function of the perineurium is extended in pathology to the removal of protein and lipid debris. In this way the perineurium contributes to the restoration of the normal microenvironment of peripheral nerve fibres.
