Since 1960 we have performed 80 colonic interpositions on 79 children. We present a retrospective review of their progress. Sixty-nine interpositions were for long-gap oesophageal atresia, while the remainder followed oesophagectomies, eight for strictures and two others. Overall, the transthoracic route was used in 69 per cent of cases, while 29 per cent(More)
Failure to thrive is a common feature of children with congenital heart disease. Whether this is the result of poor nutrition or an abnormally high basal metabolic rate is unknown, yet the state of nutrition has a profound effect on the metabolic response to injury and strongly influences the outcome of surgical treatment. The aim of this study was(More)
Despite earlier angiography, post-stenotic aneurysm of the aorta was an unexpected finding at operation in two patients with coarctation. One aneurysm was found in an intercostal artery in a 19 year old man and the other was a false aneurysm just distal to the coarctation site in a 7 year old boy. These aneurysms are fragile, apt to rupture, and difficult(More)
Povidone-iodine is an effective antiseptic, but its topical use has been associated with a number of adverse reactions in burn patients and in neonates as a result of transcutaneous absorption. In particular, high plasma iodine concentrations are known to cause renal failure, metabolic acidosis, and thyroid suppression. Because of the permeable nature of(More)
A young man with a short history of increasing dyspnea, cough, and ascites was initially diagnosed as having idiopathic constrictive pericarditis and referred for an operation. The procedure revealed an atypical invasive encapsulating disease. Complete resection was impossible, and only partial relief of constriction was achieved. The patient died shortly(More)
Postmenopausal patients with primary breast cancer were treated with tamoxifen, ethynyloestradiol or prednisolone for up to 12 days before mastectomy and the effects of pretreatments with these drugs on the activities of phosphofructokinase (PFK), 6-phosphogluconate dehydrogenase (6PGDH) and alpha-glycerolphosphate dehydrogenase (alpha-GPDH) in the(More)
From 1981 to 1987 nine patients have undergone resection and reconstruction of the oesophagus as an emergency, using a two-part left-sided approach with oesophagogastric anastomosis in the neck. Five patients had oesophageal perforation with a carcinoma; one had spontaneous perforation of an intrathoracic stomach; two had severe haemorrhage; and one had(More)
We have studied the effects of propofol, given to maintain EEG suppression throughout cardiopulmonary bypass (CPB), in 20 children aged 1-15 yr, in a parallel group comparison. Anaesthesia was produced by fentanyl 50 micrograms kg-1, enflurane or halothane and midazolam 0.1 mg kg-1 at the start of CPB. After randomization, 50% of the children also received(More)
Triiodothyronine is an important regulator of cellular metabolism and may have potential use as an inotropic agent. The aim of this study was to determine the effects of cardiopulmonary bypass on thyroid function in infants weighing less than 5 kg. Serial measurements of triiodothyronine, thyroxine, and thyroid-stimulating hormone were made in 10 infants(More)
