TL;DR: The GER Guideline Committee of the North American Society for Pediatric Gastroenterology and Nutrition has formulated a clinical practice guideline for the management of pediatric GER, and the American Academy of Pediatrics has also endorsed these recommendations.
Abstract: Gastroesophageal reflux (GER), defined as passage of gastric contents into the esophagus, and GER disease (GERD), defined as symptoms or complications of GER, are common pediatric problems encountered by both primary and specialty medical providers. Clinical manifestations of GERD in children include vomiting, poor weight gain, dysphagia, abdominal or substernal pain, esophagitis and respiratory disorders. The GER Guideline Committee of the North American Society for Pediatric Gastroenterology and Nutrition has formulated a clinical practice guideline for the management of pediatric GER. The GER Guideline Committee, consisting of a primary care pediatrician, two clinical epidemiologists (who also practice primary care pediatrics) and five pediatric gastroenterologists, based its recommendations on an integration of a comprehensive and systematic review of the medical literature combined with expert opinion. Consensus was achieved through Nominal Group Technique, a structured quantitative method. The Committee examined the value of diagnostic tests and treatment modalities commonly used for the management of GERD, and how those interventions can be applied to clinical situations in the infant and older child. The guideline provides recommendations for management by the primary care provider, including evaluation, initial treatment, follow-up management and indications for consultation by a specialist. The guideline also provides recommendations for management by the pediatric gastroenterologist. This document represents the official recommendations of the North American Society for Pediatric Gastroenterology and Nutrition on the evaluation and treatment of gastroesophageal reflux in infants and children. The American Academy of Pediatrics has also endorsed these recommendations. The recommendations are summarized in a synopsis within the article. This review and recommendations are a general guideline and are not intended as a substitute for clinical judgment or as a protocol for the management of all patients with this problem.

TL;DR: Evidence of a clinically significant benefit of probiotics in the treatment of acute infectious diarrhea in infants and children, particularly in rotaviral gastroenteritis is found, although other probiotic strains may also be effective.
Abstract: Background: This review was designed to assess the evidence from randomized controlled trials on effects of probiotics in the treatment and prevention of acute infectious diarrhea in infants and children. Methods: A systematic review of published, randomized, double-blind, placebo-controlled trials on probiotics in the treatment or prevention of acute diarrhea defined as >3 loose or watery stools per 24 hours in infants and children. Results: The use of probiotics as compared with placebo was associated with a significantly reduced risk of diarrhea lasting >3 days. The pooled estimate risk was 0.43 (95% CI, 0.34– 0.53) with a fixed-effect model, and remained significant in a random-effect model (0.40; 95% CI, 0.28–0.57). Only Lactobacillus GG showed a consistent effect. Probiotics significantly reduced the duration of diarrhea when compared with placebo, particularly in rotaviral gastroenteritis—the pooled, weighted, mean difference (WMD) assuming the random-effect model was �20.1 hours (95% CI, �26.1 to �14.2) and �24.8 (95% CI, �31.8 to �17.9) respectively. A meta-analysis of the prevention studies was not feasible because of significant clinical and statistical heterogeneity. Conclusions: There is evidence of a clinically significant benefit of probiotics in the treatment of acute infectious diarrhea in infants and children, particularly in rotaviral gastroenteritis. Lactobacillus GG showed the most consistent effect, although other probiotic strains may also be effective. Further research is needed. Clinical and statistical heterogeneity of the prophylactic interventions preclude drawing firm conclusions about the efficacy of probiotics in preventing acute gastroen

TL;DR: Although intestinal and systemic infections did not differ for HIV-seropositive and HIV-Seronegative children, HIV influenced nutritional states of all children and was associated with higher mortality.
Abstract: Background: Persistent diarrhea-malnutrition syndrome is a complex of infection and immune failure that involves protein, calorie and micronutrient depletion, and metabolic disturbances. We report an analysis of the impact of HIV infection on infectious disease, clinical presentation, and mortality in Zambian children with persistent diarrhea and malnutrition. Methods: Two hundred children (94 boys and 106 girls, 6-24 months old) were examined on admission to the malnutrition ward of University Teaching Hospital in Lusaka, Zambia. There was then I month of follow-up. Results: Antibodies to HIV were found in 108 of the children (54%) The common intestinal infections (Cryptosporidium parvum [26%] and nontyphoid Salmonella spp [18%]), septicemia (17%), and pulmonary tuberculosis confirmed by gastric lavage (13.5%) were not significantly more common in HIV-seropositive than in HIV-seronegative children. HIV-seropositive children were more likely to have marasmus whereas HIV-seronegative children were more likely to have kwashiorkor. Weight-for-age scores at nadir (postedema) were lower in HIV-seropositive children (median, -4.4; interquartile range [IQR], -5.0 to -3.8) than in HIV-seronegative children (median, -3.7; IQR, -4.2 to -3.1; P < 0.0001). Height-for-age and weight-for-height z scores and mid-upper arm circumference showed a similar difference. Of the 200 children, 39 (19.5%) died within 28 days; cryptosporidiosis and marasmus were the only independent predictors of death. Conclusions: Although intestinal and systemic infections did not differ for HIV-seropositive and HIV-seronegative children, HIV influenced nutritional states of all children. Cryptosporidiosis and marasmus were associated with higher mortality.

TL;DR: Future studies of the transcriptional and posttranscriptional regulation of the ASBT gene and analysis of ASBT knockout mice will provide further insight into the biology, physiology, and pathophysiology of intestinal bile acid transport.
Abstract: Intestinal reabsorption of bile salts plays a crucial role in human health and disease. This process is primarily localized to the terminal ileum and is mediated by a 48-kd sodium-dependent bile acid cotransporter (SLC10A2 = ASBT). ASBT is also expressed in renal tubule cells, cholangiocytes, and the gallbladder. Exon skipping leads to a truncated version of ASBT, which sorts to the basolateral surface and mediates efflux of bile salts. Inherited mutation of ASBT leads to congenital diarrhea secondary to bile acid malabsorption. Partial inhibition of ASBT may be useful in the treatment of hypercholesterolemia and intrahepatic cholestasis. During normal development in the rat ileum, ASBT undergoes a biphasic pattern of expression with a prenatal onset, postnatal repression, and reinduction at the time of weaning. The bile acid responsiveness of the ASBT gene is not clear and may be dependent on both the experimental model used and the species being investigated. Future studies of the transcriptional and posttranscriptional regulation of the ASBT gene and analysis of ASBT knockout mice will provide further insight into the biology, physiology, and pathophysiology of intestinal bile acid transport.

TL;DR: A high prevalence of celiac disease in patients with Down syndrome is reconfirms, however, the diagnostic delay, the detection of atypical symptoms or silent form in one third of the cases, and the increased incidence of autoimmune disorders suggest the need for the screening of celiasis disease in all Down syndrome patients.
Abstract: Background: A multicenter research study of Down syndrome patients was carried out to estimate the prevalence of celiac disease in patients with Down syndrome and to show clinical characteristics and laboratory data of Down syndrome patients. Methods: The authors studied 1,202 Down syndrome patients. Fifty-five celiac disease patients (group I ) were compared with 55 immunoglobulin A antigliadin-positive antiendomysium antibodies-negative patients (group 2) and with 57 immunoglobulin A antigliadin-negative antiendomysium antibodies-negative patients (group 3). Results: Celiac disease was diagnosed in 55 of 1,202 Down syndrome patients (4.6%). In group 1, weight and height percentiles were shifted to the left, whereas these parameters were normally distributed in groups 2 and 3. In celiac patients, diarrhea, vomiting, failure to thrive, anorexia, constipation, and abdominal distension were higher than in the other two groups. Low levels of hemoglobinemia, serum iron, and calcium were observed more frequently in group 1. The diagnosis of celiac disease was made after a mean period of 3.8 years from the initiation of symptoms. Sixty-nine percent of patients showed a classic presentation, 11% had atypical symptoms, and 20% had silent celiac disease. Autoimmune disorders were more frequent (30.9%) in group I than in the other two groups examined (15%; P<0.05). Conclusions: This study reconfirms a high prevalence of celiac disease in Down syndrome. However, the diagnostic delay, the detection of atypical symptoms or silent form in one third of the cases, and the increased incidence of autoimmune disorders suggest the need for the screening of celiac disease in all Down syndrome patients.

TL;DR: It is suggested that underlying celiac disease is associated with an increased risk of symptomatic hypoglycemia and that the introduction of a gluten-free diet with normalization of the intestinal mucosa may reduce its frequency.
Abstract: Background Symptomatic hypoglycemia is an unavoidable problem in the treatment of type I diabetes. Celiac disease is associated with malabsorption and may therefore represent an important risk factor. Methods The frequency of symptomatic hypoglycemia in patients with type I diabetes and celiac disease (cases) was compared with those of patients who had diabetes without celiac disease (controls). For this purpose, each case was matched for age, sex, and duration of disease with one to two control patients. Indices of metabolic control (hemoglobin [Hb]A1c, frequency of hypoglycemia, and total insulin requirement) were retrieved for the 18 months before and after diagnosis of celiac disease. Results Eighteen patients (6 males and 12 females) had diagnosed celiac disease and were matched with 26 control patients (10 males and 16 females). There was no difference in age (11.0 years; range, 1.8-21.9 vs. 13.1 years; range, 2.3-22; P = 0.3) and duration of disease (8.4 years; range, 1.2-19.3 vs. 8.3 years; range, 1.1-18.7; P = 0.3) between the two groups. During the 6 months before and after diagnosis of celiac disease the cases had significantly more hypoglycemic episodes than the controls (means +/- SD; 4.5+/-4 vs. 2.0+/-2.2 episodes/months, P = 0.01). This was reflected by a progressive reduction in insulin requirement over the 12 months before diagnosis reaching a nadir at time 0 (0.6+/-0.2 vs. 0.9+/-0.3, P = 0.05). Conclusion These data suggest that underlying celiac disease is associated with an increased risk of symptomatic hypoglycemia and that the introduction of a gluten-free diet with normalization of the intestinal mucosa may reduce its frequency.

TL;DR: Evaluated studies from trauma and intensive care centers imply that bacterial translocation is a major contributor to sepsis, shock, and multisystem organ failure in humans, but the data reviewed herein do not support that view clearly.
Abstract: Bacterial translocation is a phenomenon in which live bacteria cross the intestinal barrier. The definition may be broadened to include transmural passage of bacterial cell wall components such as lipopolysaccharide and peptidoglycan polysaccharide. After translocation, bacteria or their products reach the mesenteric lymph nodes. From there, it is possible that enteric bacteria, their cell wall components, or both may disseminate throughout the body, causing sepsis, shock, multisystem organ dysfunction, or death of the host. Bacterial translocation and its complications have been shown clearly to occur in animal models, but its existence and importance in humans has been difficult to ascertain. The purpose of this review is to evaluate the data from studies in humans on the occurrence of bacterial translocation and, more importantly, to evaluate its role as a cause of death in humans. Studies from trauma and intensive care centers often imply that bacterial translocation is a major contributor to sepsis, shock, and multisystem organ failure in humans. However, the data reviewed herein do not support that view clearly. Carefully designed studies are needed to determine the relevance of bacterial translocation in human disease.

TL;DR: This long-term prospective study shows that, although vertical transmission from HIV-negative mothers occurs in 13% of cases, there is a high rate of spontaneous viral clearance (75%) and high maternal viral load and mothers belonging to HCV risk categories were the only variables predictive of the vertical transmission.
Abstract: Background: Mother to infant transmission of hepatitis C virus (HCV) has been extensively studied in mothers with human immunodeficiency virus (HIV) infection, whereas fewer data are available on the vertical HCV transmission in HIV-negative women. Methods: Between January 1995 and June 1997, 78 consecutive HCV-positive/HIV-negative women with their offspring entered this prospective study aimed to define the prevalence of and risk factors for HCV vertical transmission. Risk factors for HCV were carefully sought, and HCV viral load and genotype were determined in all positive mothers. The infants were tested for alanine aminotransferase (ALT) and HCV-RNA at birth and at 4, 8, 12, 18, and 24 months of age. Results: Eight of 60 (13.3%) infants born to HCV-RNA positive mothers acquired HCV infection, but only 2 (3,3%) were still infected by the end of follow-up. Infants' genotypes matched that of the mothers. ALT levels were in the normal range in all study subjects throughout the follow-up. High maternal viral load (P < 0.05), possession of HCV risk factors (P < 0.004), and history of blood transfusion (P < 0.05) were associated with increased risk of HCV vertical transmission. Conclusions: This long-term prospective study shows that, although vertical transmission from HIV-negative mothers occurs in 13% of cases, there is a high rate of spontaneous viral clearance (75%). High maternal viral load and mothers belonging to HCV risk categories were the only variables predictive of the vertical transmission.

TL;DR: The prevalence of celiac disease in children with juvenile diabetes in Wisconsin is at least 4.6%, which is comparable with European and Canadian studies, and the prevalence may be even higher because patients without villous atrophy may have latent Celiac disease.
Abstract: Background The relationship between celiac disease and juvenile diabetes has long been known. Only a single study in the United States, from Buffalo, New York, has reported the prevalence of celiac disease in a pediatric diabetic population. This study was conducted to determine the prevalence and clinical presentation of celiac disease in children and adolescents with juvenile diabetes in Wisconsin, U.S.A., using serum antiendomysial antibody as a screening test. Methods Two hundred eighteen patients with diabetes (113 males; age range, 4–21 years) and 117 age-and gender-matched control participants were tested for immunoglobulin A endomysial antibody. Patients with positive results were offered a small bowel biopsy. A questionnaire regarding abdominal pain, diarrhea, and growth failure was completed by the parents. Results Seventeen of 218 diabetic patients (7.7%) had positive endomysial antibody. All control participants had negative results for the endomysial antibody. Small bowel biopsy was performed in 14 patients. Ten patients had villous atrophy. In one patient without villous atrophy, a repeat biopsy 2 years later showed villous atrophy, and two patients had increased intraepithelial lymphocytes without villous atrophy. Seventy percent of the patients with celiac disease were asymptomatic. The reported symptoms were abdominal pain and diarrhea (n = 1) and growth failure (n = 2). Two patients with celiac disease had Down syndrome. Conclusions The prevalence of celiac disease in children with juvenile diabetes in Wisconsin is at least 4.6%, which is comparable with European and Canadian studies. Because patients without villous atrophy may have latent celiac disease, the prevalence may be even higher. All children with juvenile diabetes should be screened for celiac disease.

TL;DR: Pediatric gastroenterologists skilled in ketamine administration and basic airway management can effectively administer this drug to facilitate gastrointestinal procedures to identify predictors of laryngospasm during esophagogastroduodenoscopy (EGD).
Abstract: Background Although the dissociative sedative ketamine is used commonly for pediatric procedural sedation in other settings, the safety of this agent in pediatric gastroenterology is not well-studied. A 5-year experience with ketamine sedation for pediatric gastroenterology procedures was reviewed to document the safety profile of this agent and to identify predictors of laryngospasm during esophagogastroduodenoscopy (EGD). Methods The study was a retrospective consecutive case series of children receiving ketamine administered by pediatric gastroenterologists skilled in basic airway management to facilitate pediatric gastrointestinal procedures during a 5-year period. Patient's records were reviewed to determine indication, dosage, adverse effects, drugs, inadequate sedation, and recovery time for each sedation. A multiple logistic regression analysis was performed to identify predictors of laryngospasm during EGD. Outcome measures were descriptive features of sedation, including adverse effects and predictors of laryngospasm during EGD. Results During the study period pediatric gastroenterologists administered ketamine 636 times, primarily for EGD (86%) and primarily by the intravenous route (98%). The median loading dose and total dose were 1.00 mg/kg and 1.34 mg/kg, respectively. Inadequate sedation was noted in seven (1.1%) procedures. Adverse effects included transient laryngospasm (8.2%), emesis (4.1%), recovery agitation (2.4%), partial airway obstruction (1.3%), apnea and respiratory depression (0.5%), and excessive salivation (0.3%). There were no adverse outcomes attributable to ketamine. Nearly half (46%) the subjects had severe underlying illness (American Society of Anesthesiologists [ASA] class ≥3). All instances of laryngospasm occurred during EGD (9.5% incidence), and the only independent predictor of laryngospasm in this sample was decreasing age. The incidence of laryngospasm was 13.9% in preschool-aged (≤6 years) children and was 3.6% in school-aged (>6 years) children (difference 10.3%, 95% confidence intervals 5.5–14.9%). No dose relationship was noted with laryngospasm, and the risk did not increase with underlying illness. Conclusion Pediatric gastroenterologists skilled in ketamine administration and basic airway management can effectively administer this drug to facilitate gastrointestinal procedures. Transient laryngospasm occurred in 9.5% of children receiving ketamine for EGD, and its incidence was greater in preschool than in school-aged children.

TL;DR: A cause-and-effect relationship between infant milk DHA intake and visual acuity is suggested, and there is a need to consider the optimal intake of DHA for the lactating mother.
Abstract: Background Docosahexaenoic acid (DHA), present in high concentrations in the brain and retina, has a role in visual development. DHA is present in human milk, but not in most infant formulas. It is, however, under discussion whether DHA should be added to formulas intended for term infants. The concentration of DHA in human milk, which is influenced by maternal diet, varies considerably, but it is unknown whether this variation affects visual development in term infants. Methods The authors investigated 39 4-month-old fully breast-fed term infants in a cross-sectional study. Visual acuity was measured by swept visual evoked potentials, milk DHA was determined by gas chromatography, and maternal fish intake was assessed by a frequency questionnaire. Results Frequency of fish intake correlated positively to the DHA level in breast-milk (P = 0.001). Mothers who ate fish the day before sampling had a milk DHA level higher than expected from habitual fish intake (P = 0.002). If this was taken into account, 57% of the variation in milk DHA could be explained by fish intake. Multiple linear regression analysis revealed a significant association between visual acuity and milk DHA (P = 0.02, R2 = 0.09). Conclusion This finding suggests a cause-and-effect relationship between infant milk DHA intake and visual acuity. If these data are confirmed, there is a need to consider the optimal intake of DHA for the lactating mother.

TL;DR: PSC without IBD is uncommon; asymptomatic IBD may be associated with PSC; because the time to dysplasia may be accelerated, heightened endoscopic surveillance may be indicated; and pouchitis occurs frequently in these patients.
Abstract: Background: Inflammatory bowel disease (IBD) in adults with primary sclerosing cholangitis (PSC) is characterized by pancolonic involvement, a high frequency of rectal sparing, and an increased risk of pouchitis and colorectal neoplasia. The clinical features of IBD in pediatric patients with PSC have not been well described. The aim of this study was to characterize the frequency, clinical features, and natural history of IBD in pediatric patients diagnosed with PSC. Methods: A retrospective chart review was performed for all patients 18 years of age or younger diagnosed with PSC seen at the Mayo Clinic between 1975 and 1999. Endoscopic and histologic features and surgical and postsurgical outcomes were recorded. Results: Fifty-two children with PSC were identified. Forty-three patients (84%) were also diagnosed with IBD. In 36 of 43 cases, there was a sufficient diagnostic evaluation to allow a detailed review. Thirty-two of 36 patients (89%) had ulcerative colitis and 4 of 36 patients (11%) had Crohn's disease. In 4 of 36 patients (11%), IBD was asymptomatic. Although the most frequent endoscopic presentation of IBD was universal colitis, endoscopic rectal sparing was frequently noted (27% of colonoscopic studies). Of the four patients diagnosed with Crohn disease, in none did perianal, fistulizing, or stricturing disease develop. Proctocolectomy was performed in six patients (17%); three operations were performed for dysplasia. Pouchitis complicated four of the five ileal pouch-anal anastomoses procedures. Conclusions: Among pediatric patients (1) PSC without IBD is uncommon; (2) asymptomatic IBD may be associated with PSC; (3) because the time to dysplasia may be accelerated, once the diagnosis of IBD is made in the setting of PSC, heightened endoscopic surveillance may be indicated; (4) pouchitis occurs frequently in these patients.

TL;DR: It is suggested that PEG is associated with significant late morbidity, which is mainly observed within the first 2 years after PEG insertion, however, no risk factor for the development of such complications could be identified.
Abstract: Purpose The aim of this study was to report the late morbidity of percutaneous endoscopic gastrostomy (PEG) in a pediatric population and to identify possible risk factors for complications developing after PEG insertion. Methods A PEG was placed in 110 children between 1 May 1990 and 1 January 1997 using the pull technique. A retrospective study of late-onset complications was performed, with a follow-up period ranging from 1 to 8 years. All the complications occurring more than 6 days after PEG insertion were recorded, except for gastrostomy tube obstruction and accidental tube dislodgement. Results The prevalence of late-onset complications related to PEG in our patients varied from 3.8 to 4.4 per 10 5 days. The overall rate of late-onset complications was 44% (48 complications observed in 29 patients [26%]). Seventy-five percent of the complications appeared during the first 2 years after PEG insertion. Nine different types of complication have been identified: intragastric buried or extruded gastrostomy (n = 24), gastric metaplasia granulation tissue around the site of gastrostomy (n = 8), intragastric pseudotumoral proliferative gastric mucosa (n = 4), intragastric mucosal ulceration (n = 3), cutaneous necrosis (n = 3), cologastric fistula (n = 2), gastrostomy closure delay after tube removal (n = 2), subcostal neuralgia (n = 1), and peritonitis (n = 1). Wilcoxon and chi-square tests were used to compare the clinical characteristics of the patients and the type of material used in the two populations, with and without complications. No clinical risk factor for the development of complications could be identified. Intragastric buried or extruded gastrostomy appeared more frequently with the use of one type of button than with the use of tubes. Conclusions The authors' experience suggests that PEG is associated with significant late morbidity, which is mainly observed within the first 2 years after PEG insertion. However, no risk factor for the development of such complications could be identified.

TL;DR: In sensitized infants, cow's milk induces severe gastric dysrhythmia and delayed gastric emptying, which in turn may exacerbate gastroesophageal reflux and induce reflex vomiting.
Abstract: Background: Regurgitation and vomiting are common manifestations of cow's milk protein allergy (CMPA) in infants and are usually ascribed to gastroesophageal reflux (GER). Gastric anaphylaxis can induce antral dysmotility in the rat, and therefore the hypothesis for the current study was that cow's milk in sensitized infants may impair antral motility, thereby promoting GER and reflex vomiting. Methods: Seven vomiting infants with CMPA and nine with primary GER underwent a challenge with cow's milk formula. Electrogastrography (EGG) was used to measure the spectral frequency (bradygastria = 1.5-2.4 cycles per minute [cpm], normogastria = 2.5-3.9 cpm, tachygastria = 4.0-9.0 cpm) and the postprandial-to-fasting power ratio of gastric electrical activity, whereas gastric half-emptying time (T1/2) was measured by electrical impedance tomography (EIT). Results: In CMPA and GER, respectively, during fasting, the frequency distribution (mean ± SD) of the EGG was as follows: normogastria 47.9% ± 12.5% versus 52.2% ± 9.8%, bradygastria 24.1% ± 5.7% versus 22.8% ± 8.3%, and tachygastria 28.0% ± 8.5% versus 25.0% ± 8.3%. In contrast, after the cow's milk challenge, the difference between the two groups was statistically significant: normogastria 33.1% ± 8.8% versus 70.6°% ± 8.6% (P < 0.0001), bradygastria 38.0% ± 15.5% versus 15.7% ± 5.2% (P = 0.002), and tachygastria 28.9% ± 10.6% versus 13.4% ± 4.6% (P = 0.001. The postprandial/ fasting power ratio (mean ± SD) was 3.2 ± 1.9 in CMPA and 8.1 ± 2.1 in GER (P < 0.0001). Gastric T1/2 (mean ± SD) of the cow's milk meal was 89.0 ± 26.3 minutes versus 54.0 ± 12.6 minutes (P 0.003). In infants with GER all EGG parameters and gastric T1/2 were similar to that in 10 healthy control infants. Conclusions: In sensitized infants, cow's milk induces severe gastric dysrhythmia and delayed gastric emptying, which in turn may exacerbate GER and induce reflex vomiting. Electrogastrography and EIT can be useful in the assessment of vomiting, GER, and CMPA in infants.

TL;DR: It is suggested that in some cases of intractable childhood constipation associated with colonic distention, temporary diversion improved colonic motility.
Abstract: Background Colonic manometry helps discriminate functional and behavioral causes for childhood constipation from colonic neuromuscular disease. Methods Of 375 colonic manometries performed for clinical indications, 12 could not be interpreted because of chronic colonic dilation. Based on colonic manometries that showed either no contractions or an absence of the gastrocolonic response or an absence of high-amplitude propagating contractions, the authors recommended diverting colostomies or ileostomies in 12 chronically constipated children (mean age, 4 years; range, 2-14 years, 5 boys). Before study, medical treatment was ineffective in all children. These children had persistently dilated colons with pathologic diagnoses of intestinal neuronal dysplasia (n = 4), hypoganglionosis (n = 2), hollow visceral myopathy (n = 1), and normal (n = 5). Results Six to 30 months after diversion, the authors restudied all the children. Eleven of 12 diverted colons were no longer dilated. In two patients, abnormal motility involving the entire colon was unchanged from the initial study, small bowel motility was abnormal, and we recommended no further surgery. In two cases, the colon remained abnormal but small bowel motility was normal, and we recommended subtotal colectomy and ileoproctostomy. In four cases, the left colon remained abnormal, but the right colon was normal, and we recommended reanastomosis after left hemicolectomy. In four cases, motility in the diverted colons was normal, including a gastrocolonic response and high-amplitude propagating contractions, and the authors recommended reanastomosis. Defecation problems resolved in 10 of 12 when followed up 5 to 30 months after treatment. Conclusion These data suggest that in some cases of intractable childhood constipation associated with colonic distention, temporary diversion improved colonic motility. Colonic manometry may be used to predict which patients will benefit from resection or reanastomosis.

TL;DR: Yogurt feeding is associated with a clinically relevant decrease in stool frequency and duration of diarrhea in children who have reducing sugars in stools, and can be equally well treated with feeding of either infant formula or yogurt.
Abstract: Background: The aim of this study was to compare the effect of infant formula and the same formula subjected to microbial fermentation (yogurt) on the duration of diarrhea in young children with acute watery diarrhea, with or without reducing substances in stools. Methods: One hundred twelve well-nourished children, aged 3 to 24 months, who were admitted to the hospital with acute watery diarrhea were included in a randomized trial. After appropriate rehydration, they were fed either an infant formula (group M, n = 56) or the same formula fermented with Lactobacillus bulgaricus and Streptococcus thermophilus (group Y, n = 56). The two feedings were comparable in lactose concentration (40 to 42 g/L), pH 4.5, flavor, and texture. The groups were subdivided into those with or without reducing sugars in stools at presentation. The presence of reducing sugars in stool was used as a marker of carbohydrate malabsorption. Results: Group M and group Y had comparable clinical characteristics at admission, including the number of patients with reducing sugars in stools (n = 31 in group M and 27 in group Y). The success rate (cessation of diarrhea and appropriate weight gain 7 days after enrollment into the study) was similar in both groups (82% in group M vs. 84% group Y). Clinical failure was 3.6% in both groups. The percentage of patients withdrawn from the study for medical reasons (5.4% in group M vs. 7.1% in group Y) or withdrawn at the parents' request (8.9% in group M vs. 5.4% in group Y) was similar. Duration of diarrhea and number of stools were significantly less in group Y compared with group M. Forty-eight hours after inclusion, diarrhea was still present in 62% of group M versus in 35% of group Y (P < 0.002). In children with reducing sugars in stools, the rate of success (82%) was similar in groups M and Y, but the duration of diarrhea and number of stools per day were significantly decreased in group Y. Forty-height hours after inclusion, diarrhea was still present in 75% of group M patients and in 20% of group Y patients who had reducing substances in the stool. Conclusion: Young children with acute watery diarrhea, without malnutrition or associated disease, can be equally well treated with feeding of either infant formula or yogurt. Yogurt feeding is associated with a clinically relevant decrease in stool frequency and duration of diarrhea in children who have reducing sugars in stools.

TL;DR: H pylori infection is associated with growth delay, growth retardation, or both in affected children and when weight was adjusted for age, Hpylori-positive children also had a lower weight than H plyori-negative children because of the lower weight of boys.
Abstract: OBJECTIVE: To test whether Helicobacter pylori-positive children are smaller and weigh less than H pylori-negative children. DESIGN: Cross-sectional population-based study. PARTICIPANTS: In 3,315 5-to 7-year-old preschool and school children, the putative influence of H pylori infection on growth was investigated. Standing height and weight were analyzed in relation to H pylori infection. The diagnosis of H pylori infection was established by 13C-urea-breath test. RESULTS: The prevalence of H pylori infection in boys was 7.2% (95% confidence interval, 5.9-8.9; n = 1,550) and in girls was 6.1% (95% confidence interval, 4.9-7.3; n = 1,552) H pylori-positive children were smaller than noninfected children (117.6 +/- 5.5 cm vs. 118.9 +/- 5.7 cm; P < 0.01). Although H pylori-positive boys were 2.06 cm smaller than H pylori-negative boys (117.4 +/- 5.6 cm vs. 119.5 +/- 5.7 cm; P < 0.001), the difference in girls was not significant (117.9 +/- 5.3 cm vs. 118.4 +/- 5.7 cm). When standing height was adjusted for age, the found differences were more pronounced. Differences between the infected and noninfected children with regard to body weight were not significant (22.4 +/- 4.0 kg vs. 22.1 +/- 4.0 kg), nor was there a significant difference with regard to body-mass index. However, boys with H pylori infection had a lower weight than noninfected boys (21.6 +/- 3.3 kg vs. 22.6 +/- 4.0 kg; P < 0.01), but in girls, these differences were not observed (22.2 +/- 4.0 vs. 22.8 +/- 4.6 kg, respectively). When weight was adjusted for age, H pylori -positive children also had a lower weight than H pylori -negative children because of the lower weight of boys. CONCLUSIONS: H pylori infection is associated with growth delay, growth retardation, or both in affected children.
