37. Intra-alveolar haemorrhage in sudden infant death syndrome: a cause for concern?
BACKGROUND: The "Back to Sleep" campaign in 1991 resulted in a dramatic decrease in the incidence of sudden infant death syndrome (SIDS). The proportion of presumed SIDS deaths being actually suspicious deaths from airway obstruction is likely to have become relatively greater. There is usually little pathological evidence to suggest smothering, but intra-al

38. The renal vascular response to mild and severe haemorrhage in the anaesthetized rat.
1. In order to document the characteristics of the renal vascular response to blood losses of varying severity, Inactin-anaesthetized rats were subjected to a haemorrhage of 5, 10, 15 or 20 ml (kg body weight)-1, while a fifth group (control rats) remained unbled. Radioactive microspheres (diameter 10 microns) were used to determine cardiac output, total ren

39. Cigarette smoking and subarachnoid haemorrhage: a population-based case-control study.
Smoking habits were analysed in 114 patients with subarachnoid haemorrhage, less than 70 years old, obtained from an epidemiological study. One control, matched for age, sex, and domicile, was selected for each patient. Current cigarette smokers were significantly more prevalent among cases than controls, and the relative risk of subarachnoid haemorrhage com

40. Bilateral nodular sarcoid choroiditis with vitreous haemorrhage.
A 21-year-old black man with presumed systemic sarcoidosis had bilateral choroidal nodules, unilateral retinal neovascularisation and vitreous haemorrhage, and non-caseating granulomas on percutaneous liver biopsy. The choroidal nodules were serially documented by fundus photography and fluorescein angiography over a 22-month period. Fluorescein angiography

41. Blood-stained cerebrospinal fluid: traumatic puncture or haemorrhage?
Computed tomography fails to ascertain, or exclude, the presence of intracranial haemorrhage in a considerable number of cases, especially in subarachnoid haemorrhage and haemorrhagic infarcts. A number of other methods, including cerebrospinal fluid spectrophotometry and cytology have, therefore, been tested to define their diagnostic efficacy in 25 cases o

42. Progressive systemic sclerosis complicated by diffuse pulmonary haemorrhage.
A case is reported of progressive systemic sclerosis with pulmonary fibrosis which was complicated by recurrent haemoptyses due to diffuse pulmonary haemorrhage. We have found no other report of this association. The haemorrhage finally remitted after treatment was started with 40 mg prednisone daily, though previously spontaneous remissions had occurred.

43. Renal blood flow and its distribution following haemorrhage in the rat: the role of vasopressin.
The effect of an acute arterial haemorrhage of 15 ml/kg body weight on renal and intrarenal blood flow (measured using radioactive microspheres) was determined in anaesthetized rats. In order to assess the role of vasopressin in mediating the observed changes, the response to haemorrhage of animals lacking the ability to synthesize vasopressin (Brattleboro r

44. Cerebral haemorrhage in a French prospective population study.
The incidence of cerebral haemorrhage was studied from a population-based stroke registry. The incidence was 12.3 per 100,000 per year in women and 13.9 per 100,000 per year in men, with a peak in the eighth decade and a male preponderance. Haemorrhages were deep seated and mostly due to hypertension. Recognised clinical characteristics of haemorrhage are ac

45. Vitrectomy in 125 eyes with diabetic vitreous haemorrhage.
A total of 125 consecutive eyes, all registered blind with diabetic vitreous haemorrhage, underwent pars plana vitrectomy with the vitrophage. Sixty-six per cent experienced some improvement in their visual acuity; 24 per cent were unchanged and 10 per cent were worse postoperatively. The major surgical complication was controllable haemorrhage (23 per cent)

46. Spontaneous orbital haemorrhage.
A 57-year-old housewife, with controlled hypertension, presented with acute right proptosis and visual loss with external ophthalmoplegia due to spontaneous orbital haemorrhage. Vision and ocular motility were returned to normal by the rapid surgical evacuation of the blood. Acute orbital haemorrhage is an ocular emergency requiring urgent treatment to preve

47. Detection of subarachnoid haemorrhage on early CT: is lumbar puncture still needed after a negative scan?
Computed tomography may be normal in up to 5% of patients who are investigated within one or two days after subarachnoid haemorrhage. This study investigated the need for further diagnostic evaluation after a normal CT scan was found very early (within 12 hours) in patients suspected of subarachnoid haemorrhage. A consecutive series of 175 patients with sudd
