Therapeutic use of a peptide fraction derived from bovine factor VIII in epistaxis in children

The results obtained in patients suffering from essential epistaxis in paediatric age using a peptide fraction derived from the enzymatic hydrolysis of bovine factor VIII (VUEFFE-Baldacci) are reported. Carbazochrome sodium sulphate was employed for comparison purposes. Vueffe is effective in reducing haemorrhagic episodes without modifying the laboratory parameters investigated.     

Phase II study of iproplatin in metastatic breast carcinoma

Thirty patients with progressive metastatic breast cancer and one prior chemotherapy regimen were treated with iproplatin at a starting dose of 300 mg/m2 iv every 3 weeks. After the first 11 patients, the starting dose was decreased to 270 mg/m2. There were one complete remission, three partial remissions, and two minor responses. Responses were observed in soft tissue and osseous and visceral areas. Grade 3 nausea and vomiting were observed in 38% of patients, and grade 3 diarrhea occurred in 31%. The dose-limiting toxicity was thrombocytopenia, which required dose de-escalation in 15 patients. No nephrotoxicity, neurotoxicity, or ototoxicity was observed. Iproplatin has modest antitumor activity in this group of previously treated patients with metastatic breast cancer.     

Fate of TR-2, the hepatic metabolite of the tremorgenic mycotoxin verruculogen, in sheep

1. Verruculogen is eliminated in bile after transformation to TR-2, only a trace of which was excreted as such in faeces of sheep given verruculogen per os. Negligible TR-2 was present free in urine; no glucuronide was found. 2. An isomer of TR-2, a minor component of the bile of sheep given verruculogen, has been defined by 1H-n.m.r. spectroscopy and the isomerism involves the disposition of the two adjacent hydroxyl groups with a concomitant change in the conformation of the ring adjacent to the indole. 3. 14C-TR-2, added to the perfusate of isolated rat liver, was excreted unchanged in the bile, implying no significant loss of any biliary TR-2 subject to enterohepatic recycling in vivo. 4. 14C-TR-2 incubated anaerobically in sheep ileum contents was 95% transformed into more polar metabolites, the majority of the radiolabelled metabolites isolated being water soluble. 5. The principal fate of biliary TR-2 is as a metabolic substrate for the intestinal microflora.     

A survey, in Scotland, of measures to prevent infection following orthopaedic surgery

The current use of methods, in Scotland, to prevent infection following orthopaedic surgery was established by postal questionnaire. Thirty-five per cent of surgeons used antibiotic cement routinely for total hip replacement. Ultraclean air facilities were provided for only 19%. Ninety-one per cent of surgeons used prophylactic parenteral antibiotics during total hip replacement, 75% in the management of open fractures, but only 12% for metal implants. Most chose an appropriate antibiotic. Only one-third of surgeons used an antibiotic regimen of appropriate duration and timing for total hip replacement or when employing metal implants.
