[The prevalence of viral hepatitis markers in patients hospitalized in infectious disease wards with a diagnosis of acute viral hepatitis].

According with Romanian public health surveillance system, the acute viral hepatitis is nominal reportable disease for what hospital admission is compulsory (Ord. MS 638/1978 and Ord. MS 386/1985); that why, for this condition controlling purpose, only the hospital admitted cases are reported. The acute viral hepatitis statistics do not reflect the morbidity in general population but in hospitalized population; these statistics are very dependent if ill people are hospitalized or not, and in the same time by the lack possibilities of laboratory diagnosis. The objective's study were: a) to describe the structure of laboratory-based diagnostics (using ELISA kits), b) to compare this one with diagnostics established for admitted ill people in infectious wards or clinics, using electroimmunodiffusion (EID) test. The most important findings reveal that from a total of 121 cases about three quarters has been identified as type B viral hepatitis, 20% as type A viral hepatitis and 8.3% were neither type A nor type B viral hepatitis (ELISA kits for hepatitis C diagnosis there was not available for us). According with our findings we think EID technique as etiologic diagnosis for acute viral hepatitis, have to be changed. We need instead a more sensitive and timeliness test; in the same time this has to be permissive from the financial point of view.

[The prevalence of viral hepatitis B in pregnant women in an area of southern Romania].

In Romania, the acute hepatitis B virus (HBV) infections are considered to be a public health problem. One of the most effective routes of transmission is from infected mothers to newborns both perinatal and in early childhood. That for, this study objective was to estimate the prevalence of hepatitis B în pregnant women. We used the cluster sampling method with a sample size of 1356 pregnant women. Finally our study was based on 1298 blood samples coming from 19 clusters (obstetrics wards/hospitals) selected from those 108 obstetrics wards/hospitals in the south of Romania. Overall, 31.8% (95% C.I. 27.3%-36.4%) of pregnant women admitted for birth in southern Romania had the evidence of past or current HBV infection (anti HBc, AgHBs). In a study done in 1990, Bradley A. Woodruff et al. has reported a prevalence of past or current HBV infection of 36.7% among pregnant women in northeastern Romania.

[Surgical treatment of interatrial septal defect].

On the basis of the authors' experience acquired between 1956 and 1973 (a total of 401 cases with inter-atrial communications and 234 cases of ostium secundum that have been operated by them), data are presented concerning the diagnostic means, the indications and the contra-indications of the surgical treatment, as well as the attitude to be adopted towards the associated lesions.

[Personal experience with 2,500 closed heart mitral commissurotomies].

Between 1953 and 1976 a total of 2527 mitral commissurotomies have been performed in the Clinic for Cardio-Vascular Surgery of the "Fundeni" Hospital. This group included cases with pure mitral stenosis (predominantly following rheumatic disease), but also cases of mitral stenosis associated with other cardiac lesions in which the major hemodynamic element was the mitral obstruction. Criteria are discussed for surgery, the preoperative preparation of the patient, incidents, accidents and complications, as well as technical difficulties of the digital and/or instrumental mitral commissurotomies on closed heart, either carried out for the first time in the respective patient, or as iterative intervention. Comparing the results in relation with the functional stage of the disease (62.5% of the patients were classified in the III-IV evolutive degree, according to the NIHA classification), pulmonary hypertension (61.6% of the patients had medium or severe pulmonary hypertension), associated lesions (present in 17% of the cases--mitral failure predominated, together with tricuspid or aortic failures), it is appreciated that the technique of mitral commissurotomy on closed heart is an useful therapeutic method (88.6% very good and good results, a global death rate of 3.9%) that can be applied in a large category of patients, although there is a trend toward open-heart surgery, with all medico-economical major implications.
