Percutaneous endoscopic gastrostomy (PEG) has become the modality of choice for providing enteral access to patients who require long-term enteral nutrition. Although generally considered safe, PEG tube placement can be associated with many potential complications. This review describes a variety of PEG tube related complications as well as strategies for(More)
PURPOSE Current strategies to create small-diameter vascular grafts involve seeding biocompatible, compliant scaffolds with autologous vascular cells. Our purpose was to study the composition and strength of decellularized vein to determine its potential as a vascular tissue-engineering scaffold. METHODS Intact human greater saphenous vein specimens were(More)
Seventy six children with documented Fanconi-type idiopathic infantile hypercalcaemia were studied and compared with 41 with the Williams-Beuren syndrome. Clinical comparison showed, as expected, very close similarities but also considerable differences, particularly in the severity of feeding problems and the degree of failure to thrive. The estimated(More)
A sample of 23 children aged seven to 12 years with diagnoses of infantile hypercalcaemia was assessed on a battery of psychological tests and rating scales in an attempt to describe the psychological characteristics of this disorder. All children were found to have a mild or moderate degree of mental handicap. As a group, their expressive language skills(More)
An investigation of the psychological characteristics of 44 children aged 6-16 years with documented evidence of idiopathic infantile hypercalcaemia revealed cognitive abilities and behavioural patterns which distinguish these children from other mentally handicapped groups. The children were all mildly to severely mentally handicapped, but exhibited(More)
Negative pressure wound therapy (NPWT), based on application of subatmospheric pressure, has revolutionized the management of wounds. It has been successfully used in the setting of wounds complicated by the presence of burn, infection, poor circulation, exposed bone or artificial implants, or previous wound dehiscence. Negative pressure wound therapy(More)
BACKGROUND Intensive care units (ICUs) function frequently at capacity, requiring incoming critically ill patients to be placed in alternate geographically distinct ICUs. In some medical ICU populations, "boarding" in an overflow ICU has been associated with increased mortality. We hypothesized that surgical ICU patients experience more complications when(More)
IMPORTANCE Optimizing the nature and sequence of diagnostic imaging when managing lower gastrointestinal hemorrhage may reduce subsequent morbidity and mortality. OBJECTIVES To determine if preceding visceral arteriography with computed tomographic angiography (CTA) in acute lower gastrointestinal hemorrhage increases hemorrhage identification and(More)
The authors studied changes in indices of thyroid function prospectively in a group of 11 patients given amitriptyline to treat depression. The drug caused no significant alteration in these indices, but scores on the Hamilton Depression Rating Scale improved significantly. In another group of subjects with depression, the stimulation of growth hormone(More)
OBJECTIVE Residual subclavian vein stenosis after thoracic outlet decompression in patients with venous thoracic outlet syndrome is often treated with postoperative percutaneous angioplasty (PTA). However, interval recurrent thrombosis before postoperative angioplasty is performed can be a vexing problem. Therefore we initiated a prospective trial at 2(More)
