Platelet function and coagulation in patients with hepatobiliary disorders receiving cefotetan prophylaxis.

Eighteen patients with hepatobiliary disorders undergoing invasive biliary tract investigations were given the cephalosporin cefotetan and platelet function and coagulation factors were monitored. No significant changes were observed in the group as a whole, although marked alterations were seen in three patients in association with clinical complications unrelated to the antibiotic. Although cefotetan is structurally similar to cephalosporins which have been associated with bleeding disturbances, it does not appear to induce such abnormalities in a high risk group of patients with normal renal function when given for five days intravenously at a dose of 1 g twice daily.

Clinical experience with the use of charcoal haemoperfusion: is prostacyclin required?

Twenty patients have undergone a total of 47 charcoal haemoperfusions without the use of prostacyclin. A fall in platelet numbers and evidence of platelet activation have been found during haemoperfusion but few clinical complications have been observed. Therefore, we believe that the clinical value of the addition of prostacyclin during charcoal haemoperfusion has not been proven. Nevertheless, its apparent protective effect on platelet numbers and activation indicates that further controlled trials of the use of prostacyclin during charcoal haemoperfusion are required.

How valid are our reference standards of nutrition?

The validity of anthropometric measurements in the assessment of nutritional status depends on the use of appropriate standards. The most commonly used standards for triceps skinfold thickness and mid-arm muscle circumferences are based on Jelliffe's and Frisancho's tables. In this study we compared these two standards in a population of healthy subjects and patients with a variety of pathological disorders. The study showed that the correlation between these two standards was poor. When Frisancho's standards were used as "gold standards," the positive predictive value of Jelliffe's standards for triceps skinfold thickness was only 22% and for mid-arm muscle circumference only 53%; the false positive results for triceps skinfold thickness and mid-arm muscle circumference were 28% and 27%, respectively. This study emphasizes the need to develop appropriate standards for the studied population. Until such standards are available, workers assessing nutritional status in population studies would be advised to interpret their findings with caution, and, on the basis of this study, we recommend the use of Frisancho's standard in preference to Jelliffe's standards.
