Radiation doses to children at urologic radiography.

At urologic radiography of infants and children, the energy imparted and the absorbed doses to gonads, breasts and thyroid were measured and the mean absorbed dose to the bone marrow calculated. The influence on the doses of different screen-film systems, numbers of exposures and the projection used was analysed. The risk of future radiation induced biologic effects was calculated.

Ultrasound examination of the kidney after Politano-Leadbetter ureteroneocystostomy.

Ultrasound was used in infants and children operated upon with together 62 ureteroneocystostomies to detect complicating obstructive uropathy in the early postoperative period. It was compared with isotope examination and urography. Ultrasound was reliable and accurate in appreciating urinary stasis and should thus be preferred as examination method.

Pulmonary mechanics, chest X-ray and lung disease after mechanical ventilation in low birth weight infants.

Pulmonary mechanics, chest X-ray and the incidence of clinical lung disease were studied in 41 low birth weight infants treated with intermittent positive pressure ventilation (IPPV) in the neonatal period. Shortly after IPPV most patients, irrespective of X-ray findings, had signs of lung damage reflected in low dynamic compliance or high pulmonary resistance. Both parameters, however, had a strong tendency towards normalization during the first year of life. Overdistention on chest X-ray was common at 6--12 months of age. Pneumonia and bronchitis were common during the first two years of life but subsided later on. Development of BPD or later respiratory disease were not correlated to treatment with high inspired oxygen concentrations but commonest in patients with hyaline membrane disease. The combined findings of pulmonary mechanics and chest X-ray shortly after IPPV were correlated to later clinical lung disease.

Variations in vesicoureteral reflux. Influence on diagnostic validity.

Micturition cystourethrography was performed with varying numbers of films exposed and the probability of missing a vesicoureteral reflux or underrating its severity was calculated for each series. It was concluded that a small number of exposures can give sufficiently accurate diagnosis.

Infantile hepatic haemangioendothelioma. Angiographic considerations.

Angiographic abnormalities in infantile hepatic haemangioendothelioma are analysed on the basis of previos reports and on 3 new cases. It is emphasized that the high specificity of angiography of the hepatic artery should make other diagnostic procedures unnecessary.

Infantile periarteritis nodosa or mucocutaneous lymph node syndrome. A report on four cases and diagnostic considerations.

Coronary artery aneurysm in childhood is a rare disease and has in most cases been ascribed to infantile periarteritis nodosa (IPN). In recent years a mucocutaneous lymph node syndrom (MLNS) has been found almost exclusively in Japan first described by Kawasaki 1967; this disease frequently involves the coronary arteries and myocardium. Four cases with coronary aneurysms are presented from Sweden and seem to be first described from Scandinavia. Three of these patients died a sudden death with cardiac arrest. Since MLNS and IPN have identical clinical and pathological features, we suggest that MLNS and IPN constitute a pathologic entity and that to separate them on a clinical or histological basis is nonsensical. The risk of coronary aneurysm and possible sudden death must be considered in patients with uncharacteristic symptoms including prolonged fever, conjunctivitis, exanthema, lesions in the oral mucosa, elevated sedimintation rate, and leukocytosis.

Anterior instability in the ankle joint following acute lateral sprain.

The relation between anterior instability in the ankle joint and rupture of the anterior talofibular ligament was investigated in patients with acute ankle sprains. Various techniques were used to provoke anterior displacement of the talus. The actual condition of the anterior talofibular ligament was assessed at operation. The appropriate radiographic method was defined, and its valve in diagnosing an acute rupture of the anterior talofibular ligament was assessed.
