Disappearing hypercalcaemia

Four women presented with symptomatic hypercalcaemia and raised concentrations of serum parathyroid hormone (PTH). In each case, serum calcium returned spontaneously to normal. In two patients serum PTH also fell to the normal range and biochemical relapse has not occurred despite prolonged follow-up. In the others, serum PTH remained elevated and subsequent symptomatic hypercalcaemia necessitated parathyroidectomy. In the first two cases, autoparathyroidectomy is the most likely explanation; the initial fall in serum calcium in the other two patients is unexplained. Large fluctuations in serum calcium may occur in some patients with hyperparathyroidism and prolonged and careful observation is required when this occurs.     

Walking after stroke. Measurement and recovery over the first 3 months

Sixty surviving patients had their walking ability and speed assessed regularly over the first 3 months after an acute stroke. Sixty-four matched controls were studied to allow categorisation of speed as 'slow' or 'normal'. Fourteen patients never had any significant loss of walking speed; fifteen patients never recovered the ability to walk and one patient remained dependent upon verbal support. Of the 30 showing significant recovery, only 10 regained normal speed, and 8 remained dependent upon a physical aid at 3 months. Plotting individual recovery curves of walking speed over time showed the wide range of change which may be expected. It is argued that timing of gait over 10 metres is a valid reliable measure that is currently underused.     

Chorioretinal neovascular membranes complicating contusional eye injuries with indirect choroidal ruptures.

Chorioretinal neovascular membranes are a recognised but rare cause of late visual loss in eyes suffering contusional injuries. A series of eight cases is presented all with indirect choroidal ruptures involving the perifoveal region. Two main patterns of 'at risk' rupture were noted: a temporally situated rupture passing almost directly through the fovea, and a rupture which curves inferior or superior to the optic disc stopping just short of the fovea. In six of eight cases there was only a partial thickness rupture of the choroid. These neovascular membranes may present at any time after the original injury, either early (within six months of the injury), which could be related to persistence of the normal reparative neovascular response, or late (at least one year after the injury), which are more likely to have resulted from a secondary breakdown of the outer blood-retina barrier.     

Benign symmetrical lipomatosis--a complication of excessive alcohol consumption. A case report

A case of benign symmetrical lipomatosis (Madelung-Launois-Bensaude syndrome) is described. The characteristic clinical features and the association with chronic alcoholism are reported.     

Evidence that the earliest generated cells of the murine cerebral cortex form a transient population in the subplate and marginal zone.

We used bromodeoxyuridine to label the earliest generated cells of the murine cerebral cortex while they were dividing, and then observed their distributions at several instances later in development. Shortly before birth, many of the labelled cells were either above the cortical plate, in the marginal zone, or below it, in the region known as the subplate in other species. These cells had disappeared by postnatal day 21.     

Which way for housing and human settlements?

In order to clarify the housing and settlements component of the European health-for-all programme and to identify perceived priorities with a view to the preparation of training materials, members of WHO's Rural and Urban Development and Housing Network were invited to complete a questionnaire. The results are reported below. The questionnaire can be used in identifying local development priorities, comparing attitudes, and studying perceived needs. Intended as a tool for policy-makers, course organizers and public health professionals, it is available from the authors of the present article.     

The experiential impact of head injury on adolescents: individual perspectives on long term outcome

Thirty one young people, who were experiencing chronic sequelae of a head injury sustained at least 1 year previously, were interviewed in depth about the impact head injury had had on their lives. Their functioning was also assessed using the Offer Self Image Questionnaire OSIQ R . The main theme raised by subjects was that they had not received adequate explanation of the emotional problems associated with head injury and relevant support in coming to terms with their condition. Head injury had had a devastating effect on their lives, causing limitations in day to day activities, employment, education and relationships, and they scored significantly below norms on the OSIQ R scale of Self Confidence. However, these young people had a predominantly positive attitude towards life, which appeared to be related to their appreciation of how fortunate they had been to survive. They scored significantly above norms on the OSIQ R scale of Social Functioning. Markers of poor functioning were identified and, in clinical practice, could be used as a method of highlighting those head injured young people who potentially are most in need of support. The findings have implications for future research directions, service delivery and planning, in that particular weaknesses of current provision are demonstrated and recommendations made for improvements.
