The influence of pulmonary insufficiency on ventricular function following total correction of Fallot's tetralogy: evaluation using radionuclide ventriculography and clinical findings.

Long-standing pulmonary insufficiency after repair of tetralogy of Fallot may adversely affect ventricular function. We evaluated 20 patients postoperatively by radionuclide ventriculography and clinical findings after total correction of tetralogy of Fallot. Patients were divided into two groups as follows: Group I patients (10) had no pulmonary insufficiency; Group II patients (10) had moderate or severe pulmonary insufficiency. Preoperatively, there was no difference between groups in terms of age, functional capacity according to the New York Heart Association criteria, hemoglobin and hematocrit level, cardiothoracic ratio, McGoon ratio, left and right ventricular ejection fraction, cardiac output or cardiac index. Postoperatively, right ventricular ejection fraction was 40.10 +/- 2.28 in Group I and 29.5 +/- 2.86 in Group II, p < 0.01. Left ventricular ejection fraction was 59.3 +/- 2.90 in Group I and 50.9 +/- 4.19 in Group II, p < 0.01. Radionuclide ventriculography is a useful means of identifying right ventricular dysfunction following repair of tetralogy of Fallot. The dysfunction appears significantly worse in patients with pulmonary insufficiency.

A simple management of mediastinitis.

Between January 1, 1986 and December 31, 1993, 6940 open heart procedures were performed via median sternotomy at Hacettepe University Medical Center. Mediastinitis developed in 55 patients (0.79%). Twenty-four were children. All were reoperated for treatment of mediastinitis. Following radical debridment 17 were irrigated with dilute povidone-iodine solution after primary reclosure (Group A), the remaining 38 were simply reclosed while leaving just drains in the mediastinum (Group B). Hospital mortality was 17.65% in Group A and 15.79% in Group B. Time of hospitalization after treatment in living patients was 17.6 days in Group A and 16.3 days in Group B. A mortality of 15.79% is an acceptable result which shows early radical debridment and drainage of the mediastinum is the most important cornerstone of the treatment of mediastinitis and is mostly enough with proper systemic antibiotic therapy.

Effects of oral and intramuscular vitamin K prophylaxis on PIVKA-II assay parameters in breastfed infants in Turkey.

Protein induced by vitamin K absence (PIVKA-II) has been used for the evaluation of vitamin K deficiency in the newborn. Differing PIVKA-II detection rates in various studies on hemorrhagic disease of the newborn have not been explained satisfactorily. In this study we investigated the PIVKA-II values of 44 healthy breastfed infants, of whom 29 received vitamin K1 either orally (N = 13) or intramuscularly (n = 16), and the remaining 15 constituted the control group. PIVKA-II was detected in 15.3 percent (2/13) of the oral and 25 percent of the (4/16) intramuscular group on the third day of life. The detection rate was 93.3 percent (14/15) in the control group. However, at the one-month follow-up, there were no PIVKA-II positive infants. In conclusion, PIVKA-II positivity among breastfed Turkish infants on the third day of life was high compared to that in other studies, perhaps due to a delay in enzyme maturation related to racial, environmental and nutritional factors.
