Evaluation of mesoporous silicon thermal conductivity by electrothermal finite element simulation.

The aim of this work is to determine the thermal conductivity of mesoporous silicon (PoSi) by fitting the experimental results with simulated ones. The electrothermal response (resistance versus applied current) of differently designed test lines integrated onto PoSi/silicon substrates and the bulk were compared to the simulations. The PoSi thermal conductivity was the single parameter used to fit the experimental results.

Randomized double-blind placebo-controlled trial of early octreotide in patients with postoperative enterocutaneous fistula.

Somatostatin and octreotide both enhance closure of gastrointestinal fistulas. The present trial was undertaken to test whether early combined treatment with parenteral nutrition and octreotide 100 micrograms every 8 h by subcutaneous injection had a beneficial effect compared with parenteral nutrition plus placebo. Thirty-one patients with post-operative gastrointestinal or pancreatic fistula were randomly assigned to receive parenteral nutrition plus octreotide (14 patients) or placebo (17) within 8 days of fistula onset.

Mesenteric infarction: an analysis of 83 patients with prognostic studies in 44 cases undergoing a massive small-bowel resection.

A series is presented of 83 patients surgically explored for massive bowel infarction. Old men with previous heart disease and symptoms of peripheral atherosclerosis were primarily affected. Clinical presenting features were abdominal pain (100 per cent), peritonitis (57 per cent), shock (34 per cent) and hypothermia (26 per cent).

Perforation of colonic neoplasms. A review of 36 cases.

Colonic perforation is the second most common complication of colonic neoplasms and is associated with an elevated morbidity and mortality. We undertook a two-centre retrospective analysis of 378 colonic neoplasms seen from 1978 to 1985. Thirty-six patients (9.
