Physical activity may decrease the likelihood of children developing constipation.

AIM: Childhood constipation is common. We evaluated children diagnosed with constipation, who were referred to an Icelandic paediatric emergency department, and determined the effect of lifestyle factors on its aetiology. METHODS: The parents of children who were diagnosed with constipation and participated in a phase IIB clinical trial on laxative suppositories answered an online questionnaire about their children's lifestyle and constipation in March-April 2013. The parents of nonconstipated children that visited the paediatric department of Landspitali University Hospital or an Icelandic outpatient clinic answered the same questionnaire. RESULTS: We analysed responses regarding 190 children aged one year to 18 years: 60 with constipation and 130 without. We found that 40% of the constipated children had recurrent symptoms, 27% had to seek medical attention more than once and 33% received medication per rectum. The 47 of 130 control group subjects aged 10-18 were much more likely to exercise more than three times a week (72%) and for more than a hour (62%) than the 26 of 60 constipated children of the same age (42% and 35%, respectively). CONCLUSION: Constipation risk factors varied with age and many children diagnosed with constipation had recurrent symptoms. Physical activity may affect the likelihood of developing constipation in older children.

Free fatty acid suppositories are as effective as docusate sodium and sorbitol enemas in treating constipation in children.

AIM: A well-documented, clinically proven per rectum treatment for childhood constipation is needed. This phase two clinical trial evaluated the efficacy of suppositories containing free fatty acids (FFA) compared with Klyx docusate sodium and sorbitol enemas. METHODS: A randomised, controlled, single-blind study was undertaken on 77 children aged between one and 17 who presented to an emergency department in Iceland and were diagnosed with constipation. In stage one, 23 patients were randomised to receive lower dose FFA suppositories or Klyx (n = 33). In stage two, 21 different patients were randomised to receive higher dose suppositories and compared with the same Klyx control subjects. RESULTS: The suppositories were effective at bowel emptying in 39% of the group who received the lower FFA doses and 81% of the group receiving higher doses, compared with 88% in the Klyx control group. Symptom relief was obtained in 30% of the group receiving the lower doses and 71% of the group receiving the higher doses, compared with 73% in the control group. CONCLUSION: The higher dose FFA suppositories were as effective as the Klyx enemas with regard to bowel emptying and symptom relief and might provide an important and less invasive alternative for childhood constipation.

Clinical trial: free fatty acid suppositories compared with enema as bowel preparation for flexible sigmoidoscopy.

OBJECTIVES: The purpose of this trial was to evaluate the efficacy and safety of recently developed suppositories containing free fatty acids as a bowel-cleansing agent prior to flexible sigmoidoscopy and compare them with Klyx (docusate sodium/sorbitol). DESIGN: A controlled, non-inferiority, single-blind, randomised study on outpatients undergoing flexible sigmoidoscopy. SETTING: Department of Gastroenterology, Landspitali-University Hospital and endoscopic clinic. PATIENTS: 53 outpatients undergoing flexible sigmoidoscopy. INTERVENTION: Participants were randomised to receive either free fatty acid suppositories (28) or a standard bowel preparation with Klyx enema (25). In the study group, two suppositories were administered the evening before as well as 2 h prior to the sigmoidoscopy. In the control group, Klyx enema (120 mL) was administered the evening before and repeated 2 h prior to the procedure. MAIN OUTCOME MEASUREMENTS: Quality of the bowel cleansing, height of scope insertion and safety. RESULTS: The mean height of scope insertion and bowel cleansing was 43 cm (SD=13.4) in the study group and 48 cm (SD=10.4) in the control group (NS). The investigating physicians were less satisfied with the bowel preparation in the study group compared with the control group with a difference of 20% (p<0.016). The amount of faeces noted in the rectum was similar in both groups with no significant difference (p<0.56). No serious side effects, toxic reaction or irritation were observed. CONCLUSIONS: The suppositories are well tolerated with no significant side effects. The suppositories had distinct bowel emptying effect and as effective as Klyx in rectal cleansing. Although physician's satisfaction was slightly lower, the height of scope insertion was similar. TRIAL REGISTRATION NUMBER: EudraCT nr.: 2010-018761-35.

Clinical trial: marine lipid suppositories as laxatives.

UNLABELLED: Cod-liver oil and other marine products containing polyunsaturated fatty acids have anti-inflammatory, anti-bacterial and anti-viral effects and may be useful in the treatment of various inflammatory and infectious diseases. We developed suppositories and ointment with 30% free fatty acid (FFA) extract from omega-3 fish oil. Our purpose was to evaluate the safety of marine lipid suppositories and ointment in healthy volunteers and to explore the laxative effect of the suppositories. Thirty healthy volunteers were randomized either to a study group administrating 30% FFA suppositories and applying 30% FFA ointment to the perianal region twice per day for two weeks, or to a control group using placebo suppositories and ointment in a double blinded manner. RESULTS: No serious toxic effects or irritation were observed. In the study group 93% felt the urge to defecate after administration of the suppositories as compared to 37% in the control group (P = 0.001). Subsequently 90% in the study group defecated, compared to 33% in the control group (P = 0.001). CONCLUSION: The marine lipid suppositories and ointment were well tolerated with no significant toxic side effects observed during the study period. The suppositories have a distinct laxative effect and we aim to explore this effect in further clinical trials.

[Endoscopic drainage of posttraumatic pancreatic pseudocyst in a child]. / Holsjármedferd á sýndarblödru í briskirtli.

This case report describes endoscopic drainage of posttraumatic pancreatic pseudocyst in a eleven year old boy. Pancreatic pseudocyst is a well known complication of pancreatitis and pancreatic trauma. Traditional methods of draining them consists of open surgery or transcutanous emptying. In recent years endoscopic treatment has been used more often and is now a well established treatment in the adult population. In children this kind of treatment is less well established. Our experience with this case demonstrated that endoscopic drainage is successful and safe procedure.

Diagnosis and treatment of gastric heterotopic pancreas.

BACKGROUND: Heterotopic pancreas (HP) in the stomach can be difficult to diagnose and there are many treatment options. The aim of this article is to review the contemporary diagnosis of and treatment options for HP in the stomach. METHODS: We undertook a retrospective review of patients with the diagnosis heterotopic pancreas registered at St. Olavs University Hospital in Trondheim from 1990 to 2002. We report on clinical findings, provide a histological review, and summarize the literature with particular emphasis on the diagnosis and treatment of HP in the stomach. RESULTS: We found 32 cases, most of them in the stomach and the small intestine. Sixteen patients were symptomatic. A histological examination showed that most of the tumors were submucosal and had the appearance of normal pancreas tissue. CONCLUSION: Gastric HP is not an uncommon diagnosis compared with many other gastric tumors and should more often be considered as a differential diagnosis. Symptom correlation is not always easy to determine, but symptom relief after treatment is well established. An endoscopic ultrasound examination may help when screening patients for extended biopsy and in deciding on which type of operation is to be performed. When treated, minimally invasive techniques should be applied.
