Clinical Trial Controlled Clinical Trial
Effect on mortality of community-based maternity-care programme in rural Bangladesh.
Various community-based interventions have been proposed to improve maternity care, but hardly any studies have reported the effect of these measures on maternal mortality. In this study, the efficacy of a maternity-care programme to reduce maternal mortality has been evaluated in the context of a primary health-care project in rural Bangladesh. Trained midwives were posted in villages, and asked to attend as many home-deliveries as possible, detect and manage obstetric complications at onset, and accompany patients requiring referral for higher-level care to the project central maternity clinic. ⋯ By contrast, during the following 3 years, the ratio was significantly lower in the programme than in the control area (1.4 vs 3.8 per 1000 live births, p = 0.02). The findings suggest that maternal survival can be improved by the posting of midwives at village level, if they are given proper training, means, supervision, and back-up. The inputs for such a programme to succeed and the constraints of its replication on a large scale should not be underestimated.

Patients with burns often suffer severe pain, especially during dressing of wounds, but there are no established alternatives to potent opiate analgesics, with their various side-effects. Intravenous lignocaine infusion strikingly reduced self-assessed pain scores in 7 patients during the first 3 days after second-degree burns, without need for supplementary opiate analgesia.

A rare cause of pulmonary embolism and pulmonary artery hypertension in young women is choriocarcinoma growing in the pulmonary artery. This growth is reversible, and the disorder can be cured. ⋯ Contrast-enhanced computed tomography can be used to identify major emboli, and progress of the disease can be monitored by serial ventilation/perfusion scans and measurement of serum human chorionic gonadotropin. Recognition of this rare syndrome is important because of the generally excellent outlook with appropriate treatment.

Comparative Study
Outcome in patients with subarachnoid haemorrhage and negative angiography according to pattern of haemorrhage on computed tomography.
15% of patients with spontaneous subarachnoid haemorrhage have normal cerebral angiograms; they fare better than patients with demonstrated aneurysms, though rebleeding and cerebral ischaemia can still occur. In patients with a normal angiogram and accumulation of blood in the cisterns around the midbrain--"perimesencephalic nonaneurysmal haemorrhage"--outcome is excellent. To test the hypothesis that rebleeding and disability in angiogram-negative subarachnoid haemorrhage might be limited to those with other patterns of haemorrhage on initial computed tomography (CT), complications and long-term outcome were studied in 113 patients with angiogram-negative subarachnoid haemorrhage, admitted between January, 1983, and July, 1990. ⋯ Patients with a perimesencephalic pattern of haemorrhage have an excellent prognosis. Rebleeding, cerebral ischaemia, and residual disability occur exclusively in patients with aneurysmal patterns of haemorrhage on initial CT. Repeated angiography in search of an occult aneurysm is justified only in the patients with aneurysmal patterns.

Case Reports
Safety of stringent prophylactic platelet transfusion policy for patients with acute leukaemia.
Early studies suggested that the risk of haemorrhagic complications become unacceptable when platelet counts drop below 20 x 10(9)/l. Because there are insufficient data to define 20 x 10(9)/l as the threshold for prophylactic platelet transfusions, the practicability of a more restrictive transfusion policy has been assessed prospectively in 102 consecutive patients being treated for acute leukaemia. ⋯ For patients with coagulation disorders or anatomical lesions, or for those on heparin, the threshold should be at least 20 x 10(9)/l. Such a restrictive platelet transfusion policy, which is applicable not only to thrombocytopenia associated with acute leukaemia but also to other forms of hypoproliferative thrombocytopenia, reduces exposure of such patients to blood donors and results in substantial health-care savings.
