We report our observations made clinically and by conventional radiography, ultrasound, computed tomography and MRI on a newborn full-term infant with a thrombosed patent aneurysmal ductus arteriosus of Botallo. The baby had no heart murmurs, but from the beginning of the 2nd day of life developed sinus tachycardia, especially when in a left-sided position, and dyspnoea mainly when drinking. From his 1st day of life we observed generalized muscular hypotonia and a tendency for hyperextension at neurological examination.

This report deals with a young girl affected with chronic hereditary calcifying pancreatitis, which gave rise to acute life-threatening arterial bleeding into the upper gastro-intestinal tract. A pancreatic pseudocyst forming in the chronically affected pancreas spontaneously perforated into the stomach, thereby eroding a gastric wall artery. We think it is conceivable that in the future this type of complication in children with pancreatitis and pseudocyst formation might occur more frequently.

Fractures of the sacrum and lesions of the intervertebral disks are seldom reported in childhood and adolescence. In our report, illustrated by three representative cases that we treated during the past six months, we show that sacrum fractures, not an easy diagnosis, may be more frequent than currently assumed, and that in quite a number of children and adolescents an anterior pelvic fracture may in fact be an unrecognized Malgaigne type pelvic fracture with a posterior fracture plane cutting through the sacrum. They may be accompanied by herniations and/or lacerations of intervertebral disks.
