[Frequency of Australia antigen in a heterogenous population and estimation of 3 various methods of research].

4,000 samples of serum for Australia antigen research were examined by electrosineresis. From these 4,000 serums two groups were formed afterwards: the first formed by 2,466 samples which were examined also by immunodiffusion; the second formed by 1,093 samples which were examined also by latex test; no common serum was in the two groups at the same time. AU frequence in this population sample is within the high limits of the national average. A comparison of the used methods showed the following: immunodiffusion given the smallest number of positive results; electrosineresis given other positive results besides those found out by immunodiffusion; latex test given the largest number of positive results, but greatly discordant from electrosineresis. The achieved results are examined.

[Resistance "in vitro" to several antibiotics of "Pseudomonas aeruginosa" strains isolated both in cases from the hospital and in cases from the outside. Considerations on the differences in the resistance between the two groups (author's transl)].

The sensibility of Ps. aeruginosa strains to several antibiotics has been tested in vitro. The strains have been divided into two groups: a group of 42 cases from the Hospital and a group of 31 cases from the outside. Then the percentage of resistance to each antibiotic of the cases in both groups has been calculated, and so has the significance of the differences between the percentages, whenever a difference has been found out. The strains from the Hospital have proved to be significantly more resistant to Rifampicin and to Nalidixic acid, whereas the strains from the outside have shown greater resistance to Humatin, with a semi-significant difference however. All the other differences between percentages haven't proved to be significant.

Routine coronary angioplasty with autoperfusion balloon catheter: Can prolonged inflations reduce myocardial ischemia and preserve myocardial function?

Percutaneous transluminal coronary angioplasty (PTCA) is an established technique in the management of patients with angina pectoris or acute myocardial infarction. One of the major problems related to PTCA is myocardial ischemia following balloon catheter occlusion of the coronary artery. A new device utilized in an attempt to counteract myocardial ischemia is the perfusion balloon catheter which allows passive transmission of pulsatile blood flow to the distal myocardial bed. Our purpose was to compare immediate results following traditional PTCA and autoperfusion balloon PTCA in two groups randomly assigned to receive one of the two treatments (total patients n. = 158). The results show that coronary angioplasty was successfully performed in 98.87% of patients treated with autoperfusion PTCA and in 97.10% of those treated with conventional PTCA. In the autoperfusion PTCA group we observed a lower incidence (statistically significant) of ST elevation and of minor complications. We conclude that autoperfusion balloon catheter angioplasty may be recommended for its immediate success rate with good patient tolerance and lower incidence of in-hospital complications.

[Changes in renal function in subjects undergoing an aortocoronary bypass with extracorporeal circulation].

It is well known that extracorporeal circulation (ECC) may determine an impaired renal function. The aim of our study was to identify those patients who, on the basis of the presence of cardiovascular risk factors such as diabetes mellitus, hypertension and hyperlipidemia, show more evident signs of such dysfunction. The study was conducted on 333 male patients, aged > 49 years, with normal renal function, who underwent coronary artery by-pass surgery in extracorporeal circulation. The results show that, among the cardiovascular risk factors, hypertension has a major influence on renal function after performing extracorporeal circulation, particularly on glomerular filtration rate and, when associated to diabetes mellitus, renal dysfunction may persist until the 9th post-operative day.

[Further study of the in vitro antibiotic resistance of strains of Psedumonas aeruginosa isolated in hospital and extra-hospital environments. Differences in resistance between the 2 groups].

The sensibility of Ps. aeruginosa strains to several antibiotics has been tested in vitro. The strains have been divided into two groups: a group of 162 cases from the Hospital and a group of 42 cases from the outside. Then the percentage of resistance to each antibiotic of the cases in both groups has been calculated, and so has the significance of the differences between the percentages, whenever a difference has been found out. The strains from the Hospital have proved to be significantly more resistant to neomycin, nalidixid acid, chloramphenicol, demetilclortetracyclin, rifampicin, whereas the strains from the outside have shown greater resistance to colimicin and gentamicin. All the other differences between percentages haven't proved to be significant.
