Infant botulism mimicking Hirschprung's disease
We report a case of infant botulism presenting as primary colonic ileus—mimicking Hirschprung's megacolon. Infant botulism should be considered in any infant with constipation and neurologic abnormalities.Waardenburg syndrome with extended aganglionosis: report of 3 new cases
The Waardenburg-Shah syndrome is an autosomal recessive disease with varied penetration where Hirschsprung's disease and the Waardenburg syndrome are seen together. Although the length of the involved intestinal segment varies in this syndrome, most patients had total colonic aganglionosis with or without small bowel involvement. We present in this study 2 siblings and one first-degree relative for a total of 3 male patients with Waardenburg syndrome and total colonic aganglionosis with or without small bowel involvement, together with their clinical characteristics and treatment methods.Hirschsprung's disease, acrocallosal syndrome, and congenital hydrocephalus: report of 2 patients and literature review
The L1 cell adhesion molecule (L1CAM) protein is found primarily in the nervous system and is important in neuronal adhesion, migration, neurite outgrowth, and myelination. It is extremely rare that Hirschsprung's disease (HSCR) merges with a disorder showing abnormality of the L1CAM genes such as acrocallosal syndrome (ACS) or X-linked hydrocephalus (XLH). Herein, we report 2 cases—the first showed abnormality of the L1CAM genes and developed HSCR; and the second, with clinically suspected XLH, was successfully operated on for HSCR.Hirschsprung's disease in an infant with colonic atresia and normal fixation of the distal colon
The coexistence of colonic atresia and Hirschsprung's disease presents a diagnostic and therapeutic challenge. Colonic atresia is quickly recognized, and the majority of patients are diverted shortly after birth. The diagnosis of coincident Hirschsprung's disease usually is made after anastomotic failure after restoration of intestinal continuity. A recent compilation of these patients has suggested that Hirschsprung's disease may be predicted on the basis of nonfixation of the colon distal to the atresia.Concomitant existence of total bowel aganglionosis and congenital central hypoventilation syndrome in a neonate with PHOX2B gene mutation
Hirschsprung's disease (HSCR) is characterized by the absence of intramural ganglion cells in the distal gut, resulting in bowel obstruction shortly after birth. Congenital central hypoventilation syndrome (CCHS) results in hypoventilation, most pronounced during sleep, with relative insensitivity to hypercarbia and reduced insensitivity to hypoxia. Congenital central hypoventilation syndrome with HSCR is a rare condition with variable severity. Both CCHS and HSCR are uncommon and their co-occurrence may suggest a common etiology, probably involving a fault of neural crest development.Neurocutaneous melanosis associated with Hirschsprung's disease in a male neonate
Hirschsprung's disease is an inherited disorder characterized by the absence of ganglion cells in the distal bowel. Neurocutaneous melanosis is a rare congenital syndrome characterized by proliferation of melanin-producing cells in the skin and leptomeninges. The authors described a newborn patient with neurocutaneous melanosis associated with Hirschsprung's disease. This male baby had congenital hydrocephalus, large and multiple pigmented skin nevi, and severe abdominal distension. He showed marked hydrocephalus at birth and underwent a ventriculo-peritoneal shunt at the age of 5 days.A novel Czech kindred with familial medullary thyroid carcinoma and Hirschsprung's disease
The RET proto-oncogene is involved in neural crest disorders. Activating germline mutations in the RET proto-oncogene cause the development of familial medullary thyroid carcinoma (FMTC) or medullary thyroid carcinoma (MTC) as a part of multiple endocrine neoplasia type 2 (MEN2) syndrome. Inactivating germline mutations in the RET proto-oncogene are detected in Hirschsprung's disease (HSCR). Only in a very small number of families are these 2 diseases expressed together.The combination of Hirschsprung's disease and achalasia
The unusual combination of Hirschsprung's disease and Achalasia in one case treated by standard procedures led to the discussion about RET germ-line mutations and consequently to the speculation about higher risk for multiple endocrine neoplasia syndrome type 2–related tumors. Although a mutation could be excluded by sequence analysis in this case, the correlation of these specific diseases affords additive investigations to make sure that no further prophylactic procedures were necessary.Ileo-anal S-Pouch reconstruction in patients with total colonic aganglionosis after failed pull-through procedure
Total colonic aganglionosis (TCA) occurs in 3% to 12% of Hirschsprung’s disease patients. Although numerous surgical techniques have been utilized for the treatment of these patients, little information is available regarding optimal surgical management of their frequent complications or failured procedures. The ileoanal S pouch (IASP) technique has been utilized in the treatment of children with familial adenomatous polyposis and ulcerative colitis. The authors present the results of salvage IASP in 3 TCA patients who had poor results after total colectomy and Soave pull-through.
