Epidemiology of Pneumocystis carinii pneumonia in southern Spain.

In order to investigate the impact of Pneumocystis carinii infection in southern Spain following the introduction of highly active anti-retroviral therapy (HAART), all cases of pneumocystosis between 1998 and 1999 were identified from data compiled by the national surveillance system. In total, 498 cases of pneumocystosis were recorded, of which 87% involved HIV-positive patients. The mean age, length of hospital stay and mortality were higher for HIV-negative patients. There was a higher number of cases in winter. Despite HAART implementation, pneumocystosis remains a significant health problem for both HIV-positive and HIV-negative patients.

[Aberrant left pulmonary artery (author's transl)].

Two cases of aberrant left pulmonary artery are described. One of them died on the third day of life and had esophageal atresia and Fallot tetralogy as associated anomalies. Outstanding symptoms of this anomaly were bouts of respiratory difficulty with espiratory wheezing. During these episodes radiographic findings were right or bilateral lung hyperaireation and middle lobe atelectasis. Upper respiratory infections usually preceded these bouts of respiratory difficulty. Diagnosis was established by the presence of a notch on the anterior wall of the esophagus, diminished pulmonary perfusion of the left lung as shown by pulmonary gammagraphy and characteristic findings in pulmonary arteriography. During the last 12 months the first case, now aged three years, has had a spontaneous regression of symptoms.

[Angiocardiographic study of 30 patients with complete A-V canal (author's transl)].

Authors present the results of angiocardiographic study on 30 patients with complete A-V canal. This study is divided in two parts: First, they define general concepts such as aortic suspension, anterior common valve-theoretical right border angle, left and right regurgitation, etc. Secondly, they classify A-V canal in two groups according to the following characteristics: 1) Anterior common valve normal, moderate suspension of the aorta less than 50%, rough right border of the left ventricle, angulation less than 45 degrees, medial interventricular communication and left regurgitation. 2) Common anterior valve small, important suspension of the aorta greater than or equal to 50%, smooth right border, angulation greater than or equal to 45 degrees, large communication and left and right regurgitation. Differential data between interventricular communication and valvular regurgitation are commented. They emphasize how important the posterior smooth septum and the common anterior valve are in producing the suspension of the aorta and also in the narrowing and elongation of the infundibulum. Finally, some considerations about the surgical implications according to the type of canal are made.

[Fast atrial rhythms (author's transl)].

The authors present their experience on fast atrial rhythms. Fourteen patients were studied in the first three months of life, nine of them having congestive heart failure. The electrophysiological basis of the reentrance tachycardia at A-V junction is discussed. The pharmacological treatment is reviewed, emphasizing the usefulness of verapamil. They comment on the good prognosis of the disorder, provided there is not associated congenital heart disease.

[Corrected transposition of the great arteries. Study of 14 cases (author's transl)].

We have studied 14 patients of corrected transposition, 12 with situs solitus and 2 with situs inversus. In all the patients, excepting one, a clinical, radiological and angiocardiographical study was performed. The associated anomalies were determining elements of the clinical situation; the patients with pulmonary obstruction and interventricular communication had cianosis, while the 4 patients with aortic obstruction or anomalies type left Ebstein show cardiac insufficiency. The simple radiological study helped us to determinate the ascendent aorta in the left side of the heart, in 9 cases. It was unusual to see the droped hilium in the right hemitorax. The more significants electrical signs were: The presence of complete A-V block, Q-waves in D2, D3 and aVF, absence of right waves in precordial leads in most of the patients and a negative T wave in a VL. Summarizing, authors believe that in this type of defects selective injection of contrast in both ventricles is the best method to establish the difference between corrected transposition and other cardiopathies with the aorta situated at the left side of the pulmonary artery.

[Aortic coarctation. Treatment under one year (author's transl)].

Fifteen patients operated upon for aortic coarctation under one year are reported. Nine of them survived. The E.C.G. was very useful as far as the surgical prognosis is concerned. Dead patients showed either right or biventricular hypertrophy, with alteration of the repolarisation. On the other hand 50% of survivors had left ventricular hypertrophy. In six of the operated patients a plasty between subclavian artery and aortic arch was performed. The remaining patients were treated by end-to-end anastomosis.

[Pulmonary atresia with intact i.v. septum (author's transl)].

Eight cases of pulmonary atresia with intact ventricular septum, are reviewed. Three corresponded to the group with small or hypoplastic right ventricle and five to the one with normal or enlarged right ventricular cavity. The electrocardiogram was of less value than plain chest radiography for the differential diagnosis of both groups. Cardiac catheterization revealed a right to left atrial shunt and the suprasystemic level of the right ventricular pressure. Selective angiocardiography demonstrates the stop of contrast at the level of pulmonary valve. Five patients were operated. An ascending aorta to right pulmonary artery anastomosis, Waterston type, was performed in three patients. Pulmonary valvotomy was carried out in the others.
