BACKGROUND/AIMS: Serotonin is thought to be an important neurotransmitter in the pathogenesis of irritable bowel syndrome (IBS). It is reported that functional polymorphism in the promotor region of the serotonin transporter gene is related with the subtypes of IBS and shows racial difference. However, a functional relation between polymorphism and IBS is not clear. The aim of this study was to investigate 5-hydroxytryptamine transporter (5-HTT) gene polymorphism in patients with IBS. METHODS: For fifty-six healthy controls and 33 patients with IBS fulfilling Rome II criteria, 5'-flank promotor region of 5-HTT gene was analyzed by polymerase chain reaction. RESULTS: The genotypes of healthy controls were S/S (57.1%), S/L (37.5%), and L/L (5.4%). Those of IBS patients were S/S (54.5%), S/L (36.4%), and L/L (9.1%). IBS patients were divided into three groups: diarrhea predominant (n=15; S/S, 40%; S/L, 53.3%; L/L, 6.7%), constipation predominant (n=12; S/S, 75.0%; S/L, 8.3%; L/L, 16.7%), diarrhea-constipation alternating type (n=6; S/S, 50%; S/L, 50%). There was no statistical difference in the 5-HTT gene polymorphism between patients and controls, and according to the subtypes of IBS patients (p=0.135). CONCLUSIONS: There was no relationship between serotonin transporter gene polymorphism and IBS. However, allele S/S genotype was most prominent genotype in both controls and patients.

Incidence of anterior displacement of the anus and its relationship to constipation in children.

Anterior displacement of the anus (ADA), otherwise known as "anterior ectopic anus," is considered to be a common congenital abnormality of anorectal region. However, the true incidence of this condition is not well known. We evaluated the incidence of ADA and its relationship to constipation in 357 children (191 boys and 166 girls) who were admitted to our hospital with unrelated disorders. For this purpose, the anal index was defined as the ratio of the scroto-anal distance to the scroto-coccygeal distance in boys, and as the ratio of the fourchette-anal distance to the fourchette-coccygeal distance in girls. An anal index of less than 0.34 in girls and less than 0.46 in boys was determined to be an ADA. The incidence of ADA was 43.4% in girls and 24.6% in boys (P < 0.01). However, the incidence of constipation in children with a normal anal index and those with a low anal index indicative of an ADA was not significantly different. These findings suggest that ADA is a common variant of the normal anatomical location of the anus, especially in girls.

OBJECTIVES: To determine whether there was any evidence of long-term bowel pathology in children, apparently healthy at birth, who had a prenatal second-trimester diagnosis of isolated grade 2 fetal echogenic bowel. METHODS: This was a retrospective study using data from the Oxford Congenital Anomaly Register. Fetuses with isolated grade 2 fetal echogenic bowel and date of delivery from 1994 to 2000 inclusive were identified. Information about the health of the children, particularly relating to bowel symptoms, was obtained from hospital records and from a questionnaire sent to the general practitioner. RESULTS: A total of 109 cases were identified, with delivery details available for 108. There was one unexplained intrauterine death, and additional problems were subsequently diagnosed in four cases (cystic fibrosis (2), Down syndrome (1), and VACTERL (1)). Questionnaires were sent to the GPs of the 103 who had no problems identified at the time of discharge from the maternity hospital. Age at follow-up ranged from one to four years. Responses to the questionnaires were received from 83 (81%). Of these, 74 (89%) had not reported bowel symptoms to the GP, 9 (11%) reported symptoms relating to constipation (6), chronic abdominal pain (1), infantile colic with milk intolerance (1) and gastro-oesophageal reflux (1). CONCLUSION: This small study provides some reassurance that there was no evidence of any serious long-term bowel pathology associated with isolated fetal echogenic bowel.
