The Council Directive of the European Communities 97/43/Euratom requires dose assessment, especially for X-ray examinations of children and if high doses to the patient are involved. Both these aspects apply in cardiac catheterization and angiocardiography of children. Effective doses are a good indicator of radiation risk, particularly for leukaemia.(More)
We have analysed growth and the major clinical manifestations of 144 patients (89 males, 55 females) with Noonan syndrome from two West German centres. Size at birth was normal in both sexes. In both males and females, the mean height followed along the 3rd per centile until puberty, but decreased transiently due to an approximately 2 year delay in onset of(More)
In three of nine children with dilated cardiomyopathy (aged 1–9 years), left ventricular thrombi were diagnosed and followed by echocardiography. Thrombi recurred in two patients, in one of them, embolized to the cerebral arteries. Resolution of the thrombi was observed under therapy directed against platelet aggregation. However, this did not prevent(More)

Meiotic chromosomes of spermatocytes from INH-treated male mice and Chinese hamsters were analysed for chromosome aberrations in diakinesis-metaphase I and metaphase II. The experiments were performed in two laboratories while a third laboratory participated in the chromosome evaluation. No enhancement of chromosome aberrations could be observed after acute(More)
OBJECTIVE To define the problems encountered during transcatheter occlusion of the patent arterial duct using Gianturco coils. METHODS Between January 1994 and November 1995, 93 patients were admitted in whom it was intended to occlude the patent arterial duct using Gianturco coils. Anterograde transcatheter coil occlusion was performed via the femoral(More)
Isolated noncompaction of the myocardium, also known as "spongy myocardium", is a rare disease in children and adults. It is suggested that, during early development of the heart, the primary spongy structure persists due to an arrest of compaction. No other cardiac malformations are found, but there are familial occurences, relations to genetic disorders(More)
Balloon valvuloplasty (BVP) of pulmonary stenosis (PST) was performed in 305 infants and children in 20 heart centres of the Federal Republic of Germany. 273 patients suffered from isolated PST. Their age ranged from 3 days to 18 years (mean = 5.85 +/- 4.82 years), their weight from 2.9 to 60 kg. The pressure gradient was measured invasively in the sedated(More)
Three infants, each with a clinical picture of dilated cardiomyopathy, underwent endomyocardial biopsy. Immunohistologic analysis revealed chronic myocarditis. In one infant, a postviral etiology of chronic myocarditis could be assessed on the basis of molecular techniques. Therapy with azathioprine and prednisone resulted in the normalization of(More)
