An abnormal distribution of C-kit positive cells in the normoganglionic segment can predict a poor clinical outcome in patients with Hirschsprung’s disease. One of the latter continued to have a daily average of two normal bowel motions during a follow-up period of more than two years following completion of surgery.
Interstitial cell of Cajal
ICC are also critical in the propagation of electrical slow waves. Variations in the distribution of the ICCs have been ascribed to variables such as patient age and the level of the bowel being assessed, as well as to a number of clinical conditions, which include Hirschsprung’s disease HD and its variants and congenital anorectal anomalies ARM. The Impact Factor measures the average number of citations received in a particular year by papers published in the journal during the two receding years.
Abnormal colonic interstitial cells of Cajal in children with anorectal malformations.
Interstitial cell of Cajal – Wikipedia
Altered distribution of interstitial cells of Cajal in Hirschsprung disease. However, this observation has not been unanimous and most investigators, while confirming a reduced density in aganglionic bowel, have found the distribution of these cells in the proximal ganglionated bowel of patients with HD to be identical to that of normal colon 7, Cells with features of ICCs were counted.
These ICC-Ms have been shown to be coupled to smooth muscle cells via gap junctions which allow them to function as electrical conductors 6. SNIP measures contextual citation impact by wighting citations based on the total number celuals citations in a subject field.

The study being presented, though involving a small number of patients, supports the possibility of an effect of age, gender and the level of bowel studied on the density of these cells. The latter theory is favoured by the occasional finding of normal ICC counts ce aganglionic bowel as occurred in two of our patients. However, users may print, download, or email articles for individual use.
Postmortem intervals for the autopsy cases were less than 24 hours. This is in accord with previous studies where myenteric ICCs were shown interstjciales be greatly reduced or absent in aganglionic bowel and sparse in the transitional zone. Arch Pathol Lab Med.
Retrieved 14 April Fluids Bile Pancreatic juice. Continuing navigation will be considered as acceptance of this use. Segments of bowel wall excised from eight children with HD, three controls and two felulas with ARM were immunostained with c-Kit primary antibody.
Electrical slow waves spread from ICC to smooth muscle cells and the resulting depolarization initiates calcium ion intersticialles and contraction. The tissue blocks of three of the aganglionic biopsies either could not be located or had insufficient tissue available for further processing.
SRJ is a prestige metric based on the idea that not all citations are the same. The journal fully endorses the goals of updating knowledge and facilitating the acquisition of key developments in internal medicine applied to clinical practice.
For the cell in the midbrainsee Rostral interstitial nucleus of medial longitudinal fasciculus. Animals lacking ICC have greatly reduced responses to the neurotransmitter acetylcholinereleased from excitatory motor neurons, and to the transmitter nitric oxidereleased from inhibitory motor neurons. Acta Physiol Scand ; Counts from the stomata of the two patients with ARM ranged from to A case for interstitial cells of Cajal as pacemakers and mediators of neurotransmission in the gastrointestinal tract.
Thus, six of the eight children with HD had marked diminution of ICCs in aganglionic bowel and two in ganglionic bowel. Servicio de Medicina Interna. CiteScore measures average citations received per document published. The two children with normal counts in aganglionic bowel were both male at or under the median age of two years.
