A review of the causes of death in 276 patients with sickle-cell disease showed that although the greatest mortality occurred in the first five years of life, roughly one-quarter were aged over 30. Commonest causes of death in the first ten years included acute splenic sequestration, septicaemia, meningitis, aplastic crises, and gastroenteritis. In older(More)
We reviewed our experience with tracheal and bronchial trauma from 1977 to 1988. There were 22 patients with tracheobronchial injuries treated in this period. Seventeen (77%) of the injuries were due to penetrating trauma and five (23%) were due to blunt trauma. Thirteen patients had major associated injuries, including six esophageal injuries. The most(More)
We describe the implementation of a glucose control protocol supported by a web-based insulin dose calculator in a 16-bedded intensive care unit. The protocol was introduced and then modified after 15 months' use. Glucose concentrations were retrospectively reviewed and compared for the 9-month period before introduction of the protocol (288 patients), for(More)
Sixty-nine patients with perforation of the esophagus were treated at the University of California, San Francisco, from 1977 to 1988. The perforation was iatrogenic in 33 (48%) of the patients, spontaneous in 8 (12%), and a result of external trauma in 23 (33%). Clinical findings included chest pain in 36 (52%) of 69 patients, subcutaneous emphysema in 22(More)
Background and purpose: To follow up in vitro evidence that D-tetrahydrocannabivarin extracted from cannabis (eD-THCV) is a CB1 receptor antagonist by establishing whether synthetic D -tetrahydrocannabivarin (O-4394) and D-tetrahydrocannabivarin (O-4395) behave as CB1 antagonists in vivo. Experimental approach: O-4394 and O-4395 were compared with eD-THCV(More)
Leptin concentrations were measured in the serum of cycling, pregnant, and lactating Sprague-Dawley rats. Serum leptin concentrations did not vary significantly during the estrous cycle. In contrast, as gestation advanced, serum leptin concentrations increased significantly, p < 0.0001. Following delivery, leptin concentrations declined and remained stable(More)
We used key words and letter sequences to identify airway-associated patient safety incidents submitted to the UK National Patient Safety Agency from critical care units in England and Wales. We identified 1085 such airway incidents submitted in the two years from October 2005 to September 2007. Three hundred and twelve incidents (28.8%) involved neonates(More)
1. Hormone replacement therapy (HRT) with oestrogen or oestrogen plus progestin may have different effects on arterial structure and function. To examine this question, carotid artery intima-medial thickness (IMT) and indices of systemic and carotid arterial compliance were measured in groups of older men, postmenopausal women not on HRT (non-HRT) and those(More)
We reviewed all patient safety incidents reported to the UK National Patient Safety Agency between August 2006 and February 2007 from intensive care or high dependency units. Incidents involving equipment were then categorised. A total of 12 084 incidents were submitted from 151 organisations (median (range) 40 (1-634) per organisation). Of these, 1021(More)
