[Variations in serum kininase II activity in acute jaundice].

An assay of Kininase II activity in the serum of 92 jaundice patients revealed a significant difference between the group with viral hepatitis (268.48 +/- 70.93 U/ml), that with biliary obstructions (133.05 +/- 37.64 U/ml) and with cirrhosis (173.76 +/- 79.56 U/ml). The increase encountered in patients with medical jaundice correlates well with total bilirubinaemia but not with cytolysis enzymes. This suggests failed demolition of ACE by the hepatocyte during cellular stress.

[Exogenous infections and environmental flora. Criteria for the characterization of bacteria and parameters influencing their spread].

An assessment was made of environmental micro-organisms isolated in the University of Turin Intensive Surgical Care Unit and Emergency Surgery Department to determine the possible exogenous origin of post-operative infections. The enzymatic characters and antibiotypes were determined for some species, and subsequently compared with similar characters of the "in vivo" isolated flora. A monthly disinfection method based on comparison among three antiseptic agents (chlorexidine, formaldehyde and formotetronium) considerably reduced the flora. The data obtained, while showing that most of the infections observed were endogenous, also provided indications on the way in which the spread of certain Gram-negative germs, often involved in post-operative and post-traumatic infections, could be contained.

Autotransfusion and emergency surgery: preliminary report on an improved technique.

A new improved technique of erythrocyte autotransfusion is described. Autologous blood aspirated from the operative field is centrifuged, washed and reinfused in 5-10 minutes. The systems is composed of a centrifuge and vacuum pump built into the machine. The disposable set is very easy to assemble, and cost-effective. Preliminary data of 19 patients operated as emergency cases are shown. None had postoperative bleeding. Platelet count and function did not change. Even in the cirrhotic patients there were no changes in coagulation two hours after autotransfusion. The system seems easy to use, cost-effective and particularly indicated in emergency surgery.

[Teleconsulting and telediagnosis in emergency surgery].

A colour video picture transmission system in real time with data transmission via a broad wave optical fibre cable has been set up to link Turin University's Orthopaedic Traumatology Centre and Emergency Surgery Clinic. The system consists of two stations. The transmitter station is equipped with a mobile TV camera or TV monitor and various electrical medical equipment. The receiving station consists of a picture reception monitor. The coded video signal is transmitted via the optical fibre; sound transmission is via a special telephone line. This experimental system was set up to see if patients with multiple injuries could receive diagnosis at a distance, thus avoiding unnecessary travelling. Experience of 100 link-ups has demonstrated that the system effectively cuts diagnosis and therapy times and is as efficient as in loco inspection by a surgeon. In addition it can be used to provide specialised consulting services to rural hospitals without special equipment. This reduces waiting times for emergency treatment and can also prevent the pointless transfer of patients to big hospitals in cases where the specialist can prescribe intermediate therapy or surgery.

[Diagnostic and prognostic value of the carcinoembryonic antigen in colonic cancer].

A group of 50 patients operated for carcinoma of the colon in June 1980-December 1981 with a follow-up period of min. 2 months-max. 15 months is presented. C.E.A. measurements were taken in all patients pre and post-operatively and then every 2 months in an attempt to establish its diagnostic and prognostic value. In immediate diagnostic and prognostic terms, pre-operative C.E.A. appears to be insignificant. However both pre-operative C.E.A. and C.E.A. at a distance of 6 months were found to be reliable for long term (max. 15 months) prognosis.
