A case of neuronal colonic dysplasia in association with Hirschsprung's disease is described. It is suggested that this condition be borne in mind when investigating operated Hirschsprung's cases having residual symptoms.
Six cases of testicular tumors in children are presented: 3 patients had teratoma, 1 embryonal carcinoma, 1 orchioblastoma, and 1 paratesticular rhabdomyosarcoma. Three of the 6 patients presented with hydroceles. The treatment consisted of orchiectomy alone. All patients were alive and free of disease one and one-half to eight and one-half years after orchiectomy. It is suggested that orchiectomy alone is curative in most children with testicular tumors under the age of two years.
A case of adynamic bowel syndrome is described. Full thickness biopsies of the large bowel showed the presence of ganglion cells, no acetylcholinesterase positive nerves in the lamina propria, submucosa or among the smooth muscle cells of the circular and longitudinal muscle coats, and absence of the argyrophil plexus. Electron microscopic examination showed replacement of the normal axon bundle by vacuolated tracts with small round bodies in one area--probably viral. Neuronal cytoplasm also showed similar vacuolation. It is suggested that the damage to the cholinergic innervation may be caused by a neurotoxic agent.
Twelve patients with gallstones were operated at Our Lady's Hospital for Sick Children in Dublin from 1960 to 1973. Seven patients were dealt with by cholecystolithotomy and followed up for periods ranging from 18 months to 13 years. All cases were in good health without any evidence of recurrences of calculi. Three cases 11 to 13 years after cholecystolithotomy showed normally functioning gall bladder on cholecystography.
84 of 89 cases were traced 18 to 27 years after Swenson's operation. Seven had long segments. All were alive and in good general health except one who had renal transplant for hypertension due to pyelonephritis in a residual solitary kidney. 61 are married of whom 34 have children. None of the children have Hirshsprung's disease. 48 were fully normal within one year of operation. 29 had constipation enough to require treatment. Seven had diarrhoea which in three required hospitalisation for electrolyte disturbances and dehydration. 39 had some degree of soiling, but in only nine was this troublesome. Recovery of normal bowel control was more rapid in those with a good social background. Eight had postoperative strictures, but treatment has remained successful in the long-term in seven of these. Five patients had inadequate resections and are well after further surgery. Nine had urinary incontinence of which seven had only nocturnal enuresis. All are fully recovered. Two male patients have absence of ejaculation and two females are infertile with scarred Fallopian tubes. 83 of the 84 now have normal bowel control and good health. One has a permanent ileostomy.
A procedure is described which combines the posterior liberation of the levator with the levator plication. This operation was performed in 15 children, born with anorectal agenesis, all of whom were incontinent of feces after primary operation. Four of the 15 children became fully continent following levatorplasty, seven patients now have only occasional soiling, and four patients continue to soil persistently. In all the cases, a good correlation was found between bowel control after levatorplasty and anal canal pressures. Normal resting anal canal pressure was as significant as the voluntary squeeze pressure in relation to continence.

Internal sphincteric function was studied manometrically in 19 children with translevator anal anomalies. The normal internal sphincter inhibitory response to rectal distension was present in ten pateints, attenuated in six, and absent in three. Our findings suggest that a functional internal sphincter is usually present in translevator anal anomalies.

A case of intrahepatic atresia in Down's syndrome is presented. It seems likely that atresia of intrahepatic bile ducts in Down's syndrome is due to a chromosomal disorder.
Fifteen infants with life-threatening gastrointestinal anomalies received total parenteral feeding for periods ranging from 10 to 54 days; their ages ranged from one day to 5 months. The solutions were administered through peripheral veins. All patients gained weight during the period of observation and no cases of septicaemia were encountered.

Hirschsprung's disease (HD) is a relatively common cause of intestinal obstruction in the newborn. It is characterized by an absence of ganglion cells in the distal bowel beginning at the internal sphincter and extending proximally for varying distances. The etiology of HD-associated enterocolitis remains a complex issue. This study has provided further support for a possible infectious etiology of enterocolitis complicating HD.
We report a case of acute carpal tunnel syndrome from thrombosis of a persistent median artery caused by blunt trauma. The sudden onset of numbness in the median nerve distribution with pain in the fingers in a young adult may provide clues to the diagnosis.
