Abstract: In the 4 years January 1981 to December 1984, 186 children received 1362 halothane anaesthetics. Twenty-five patients were anaesthetized with halothane at least 10 times in a year. No patient developed postoperative jaundice. Sixty-nine children were exposed to two halothane anaesthetics within 28 days on 149 occasions and serial estimations of serum liver enzyme concentrations were obtained. Minor increases in the concentrations of serum AST and ALT were recorded in 10.6% and 4.7% of patient entries, respectively. Postoperative GGT and SAP concentrations were increased in 2.7% of patient entries. Patients in whom enzyme values were increased before the first anaesthetic were no more likely than other subjects to develop further changes.

Yes

Abstract: Protein S deficiency is inherited as an autosomal dominant trait. Heterozygotes with a reduction of 50% in the plasma protein S concentration are at risk for the development of venous thromboembolism, often occurring at an early age without an apparent cause. In the majority of the patients thrombosis is restricted to the superficial or deep venous system of the legs. In this case report we describe the presence of mesenteric vein thrombosis in a 30-yr-old man with hereditary protein S deficiency. In his family protein S deficiency was also recognized in his mother, brother, and niece. Both his mother and brother had a history of thrombotic disease.

Abstract: We have previously reported that lymph from the chronic sheep lung lymph preparation contains 25-60% lymph from nonpulmonary sources. In subsequent studies we found that the lymph flow rate from cannulated lymph vessels depends on the resistance and position of the lymph cannula. Because we did not account for these factors in our estimate of the amount of nonpulmonary lymph in the sheep lung lymph preparation, our data were not accurate. We probably overestimated the amount of nonpulmonary lymph. However, the presence of nonpulmonary lymph remains a potentially serious problem with the sheep lung lymph preparation.
