Intussusception in Newcastle in a 25 year period.

The history of intussusception in Newcastle in a quarter of a century is presented by analysis of patient presentation and the results of management. The figures for the early years are incomplete, retrieved from one hospital in the area. For the years 1976-1988, all cases were managed by two paediatric surgeons who kept individual disease indices. One hundred and sixty-five episodes of intussusception in 153 patients were reviewed in this study. There was one death in the series, whereas there had been several in the years preceding it. There has been an improvement in the success of hydrostatic and later pneumatic reduction. These changes are attributed to the development of appropriate skills resulting from concentration of the management of this problem in the hands of paediatric surgeons and radiologists with special training and interest in paediatrics. Enema reduction has been used more aggressively in recent years and has widened criteria. In the series there were 8 patients with causal lead points, none associated with recurrence. The overall recurrence rate within the series was estimated at 8%. There seems to be a high incidence of intussusception in doctors' families.

Adrenal haemorrhage presenting as an abdominal mass in the newborn.

Adrenal haemorrhage in the newborn, an entity well recognized at autopsy and as a cause of massive haemorrhage, may present as an asymptomatic abdominal mass. Three cases of neonatal adrenal haemorrhage are described and the literature is reviewed. Most of the affected babies were of normal birthweight, full term and with no history of difficult delivery or neonatal asphyxia. Most presented with a flank mass and jaundice. The haemoglobin was not always low. Intravenous urography and sonography were the investigations of choice. The most serious condition in the differential diagnosis is neuroblastoma, but the chance of this presenting in the newborn period with normal catecholamine secretion and no evident metastases is sufficiently rare to justify expectant management. Follow-up physical examination and repeat sonography at 1 month are recommended. This interval is long enough to allow resolution of a mass caused by adrenal haemorrhage.

Percutaneous nephrostomy in infants and children.

Percutaneous nephrostomy drainage was established in 28 children, predominantly for ureteric obstruction. Infection was the most frequent presenting feature (nine patients) followed by renal failure (six) and a combination of the two (four). A sonographically guided antegrade examination was first performed with a 22-gauge needle. Using a posterolateral approach, a 6 or 8.3 French pigtail catheter was placed in the collecting system over a guide wire introduced through an 18 gauge needle. Catheter placement was successful in every patient; in 15 children, no further procedures were required. Complications were uncommon and usually minor.

Computed tomography in the management of paediatric abdominal trauma.

Since the installation of a whole body computed tomography (CT) unit at the Royal Alexandra Hospital for Children in March 1978, it has been shown to play an invaluable role in the management of abdominal trauma in selected cases. Our experience with 16 cases is presented, and the advantages of CT over alternative diagnostic aids are discussed.
