Improving the Nutritional Status of Socially Vulnerable Children in Manaus, Brazilian Amazon, through a Food Supplementation Programme. Nutrients 2024; 16:1051. [PMID: 38613084 PMCID: PMC11013924 DOI: 10.3390/nu16071051] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2023] [Revised: 03/15/2024] [Accepted: 03/19/2024] [Indexed: 04/14/2024] Open
Abstract
Information on the effects of government nutrition programmes provided to socially vulnerable children to improve their nutritional status is scarce. We analysed the effectiveness of a nutritional programme, including food supplementation with infant formula, on the evolution of the weight and height of socially vulnerable children from Manaus in the Brazilian Amazon. This study included 7752 children aged 12-24 months admitted to the programme between 2017 and 2020. Weight and height measurements at admission and every three months thereafter were extracted from the programme database. Weight-for-age, weight-for-height, body mass index-for-age (BMI/A), and height-for-age z-scores were analysed using a multilevel linear regression model, which showed a statistically significant decrease in nutritional deficits toward nutritional recovery at follow-up. The programme's effectiveness was evaluated in 1617 children using a paired analysis comparing data from between 12 and 15 months of age at admission and follow-up after 6-9 months. Children admitted with wasting presented an increase in the BMI/A z-score, whereas children admitted with a risk of being overweight and obese had a statistically significant decrease in the BMI/A z-score. Children admitted with stunted growth also showed increased height-for-age z-scores. The nutrition programme was effective for children experiencing wasting and reducing excess weight.

Assessing impaired gastric accommodation in children with functional constipation using the water load test. Neurogastroenterol Motil 2024:e14786. [PMID: 38523297 DOI: 10.1111/nmo.14786] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/20/2023] [Revised: 01/31/2024] [Accepted: 03/11/2024] [Indexed: 03/26/2024]
Abstract
BACKGROUND This study aimed to evaluate gastric accommodation in pediatric patients with functional constipation using the water load test. METHOD This was a cross-sectional case-control study. Herein, the water load test results of children aged >4 years with functional constipation referred to a Pediatric Gastroenterology Outpatient Clinic (functional constipation group) were compared with those of a control group (without functional constipation or chronic abdominal pain) recruited from two public schools. Clinical manifestations outlined in the Rome IV criteria were used to diagnose functional constipation. Water load tests were performed after 3 h of fasting. For the test, the participants were asked to drink as much water as possible in 3 min. KEY RESULTS A total of 36 patients and 77 students were included in the functional constipation and control groups, respectively. There was no significant difference in age between the groups (8.6 ± 2.3 years and 8.8 ± 1.8 years in the functional constipation and control groups, respectively). The water load test showed intake volumes of 390 ± 245 mL and 528 ± 219 mL in the functional constipation and control groups, respectively (p = 0.001). The maximum volume in the water load test correlated with the 24 h daily intake of energy (rS = +0.42, p = 0.012), protein (rS = +0.48, p = 0.004), and water (rS = +0.39, p = 0.020) only in the group with functional constipation. CONCLUSIONS & INFERENCES According to the water load test, gastric accommodation was impaired in children with severe functional constipation. The impairment of gastric accommodation in children with severe functional constipation is related to food intake.

Abstract
This school-based, cross-sectional study aimed to evaluate whether hypohydration is related to functional constipation and physical activity in school-aged children. The study included 452 students aged 6-12 years. Hypohydration, defined as urinary osmolality >800 mOsm/kg, was more prevalent ( P = 0.002) in boys (72.1%) than in girls (57.5%). The difference in the prevalence of functional constipation according to sex (20.1% in boys and 23.8% in girls) was not statistically significant ( P = 0.81). In bivariate analysis, functional constipation was associated with hypohydration in girls (odds ratio = 1.93, 95% confidence interval: 1.07-3.49), and multiple logistic regression did not reach statistical significance ( P = 0.082). Low proportions of active commuting to school in both sexes were associated with hypohydration. However, there were no associations between functional constipation, active commuting to school, and physical activity scores. In conclusion, multiple logistic regression did not demonstrate an association between hypohydration and functional constipation in school-aged children.

Overweight status, abdominal circumference, physical activity, and functional constipation in children. REVISTA DA ASSOCIACAO MEDICA BRASILEIRA (1992) 2023; 69:386-391. [PMID: 36820766 PMCID: PMC10004292 DOI: 10.1590/1806-9282.20220845] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/01/2022] [Accepted: 12/14/2022] [Indexed: 02/22/2023]
Abstract
OBJECTIVE The aim of this study was to assess the prevalence of functional constipation and its relationship with the food intake, overweight status, and physical activity of children. METHODS This cross-sectional study included students from two public schools in the municipality of Osasco, which is located in the metropolitan area of São Paulo. Functional constipation was diagnosed if the clinical manifestations of the Rome IV criteria were present for more than 2 months. A 24-h recall survey was used to determine the daily food intake. Weight, height, abdominal circumference, and bioelectrical impedance were used to evaluate the weight status. Active commuting to school and physical activity scores were assessed using a questionnaire that has been validated in Brazil. RESULTS A total of 452 children, aged 6-12 years, were evaluated. Functional constipation was observed in 22.3% of participants. A greater abdominal circumference was associated with functional constipation in girls (p=0.036) in the bivariate analysis but not in the logistic regression model. Boys with functional constipation consumed higher quantities of fats (p=0.041). There was no statistically significant relationship between functional constipation and overweight status (44.6 and 34.5% of children with and without constipation, respectively; p=0.083) and active commuting to school (48.5 and 56.7% of children with and without constipation, respectively; p=0.179). CONCLUSION Functional constipation was associated with a greater abdominal circumference in girls in the bivariate analysis, however, without association in the logistic regression model. Boys with functional constipation consumed higher quantities of fat. No association was found between functional constipation, overweight status, and physical activity.

Prematurity and functional gastrointestinal disorders in infancy: a cross-sectional study. SAO PAULO MED J 2022; 140:540-546. [PMID: 35648986 PMCID: PMC9491473 DOI: 10.1590/1516-3180.2021.0622.r1.29102021] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/04/2021] [Accepted: 10/29/2021] [Indexed: 11/22/2022] Open
Abstract
BACKGROUND Functional gastrointestinal disorders (FGIDs) are defined as a variable combination of chronic or recurrent gastrointestinal symptoms that are not explained by structural or biochemical abnormalities. Their relationship with prematurity has been increasingly studied. OBJECTIVE To compare the frequency of FGIDs in preterm and term infants and to evaluate whether invasive procedures during the neonatal period in preterm infants are associated with greater likelihood of FGIDs in the first two years of life. DESIGN AND SETTING Controlled nested cross-sectional study conducted in a Brazilian university hospital. METHODS This was a controlled nested cross-sectional study on a retrospective cohort of infants born preterm who were compared with infants born at term regarding the presence of FGIDs. Medical consultations were conducted by a single pediatric gastroenterologist to obtain information on the gestational and neonatal periods and on clinical manifestations of the digestive tract. The Rome IV criteria for the diagnosis of FGIDs were used. RESULTS A total of 197 infants (< 24 months), including 99 preterm and 98 term infants, were studied. Infant regurgitation was more prevalent in term infants (35.1% and 15.6%; P < 0.001). The frequencies of other FGIDs (infant colic, functional constipation, functional diarrhea and infant dyschezia) in preterm infants did not differ from those of term infants (P > 0.05). No relationship was found between invasive procedures during the neonatal period and development of FGIDs in preterm infants. CONCLUSION Infants born preterm did not have higher frequency of FGIDs in the first two years of life.

THE FATIGUE RATE INDEX IS HIGHER IN CHILDREN WITH FUNCTIONAL CONSTIPATION AND RETENTIVE FECAL INCONTINENCE. ARQUIVOS DE GASTROENTEROLOGIA 2022; 59:428-433. [PMID: 36102443 DOI: 10.1590/s0004-2803.202203000-76] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Accepted: 06/22/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND The Fatigue Rate Index (FRI) is a parameter in anorectal manometry (ARM) to assess sustained voluntary contraction, considering the squeeze pressure and fatigability of the external anal sphincter. It is used in adults to detect fecal incontinence even in patients who present normal squeeze pressures. The FRI in adult patients with functional constipation is similar to controls. OBJECTIVE The aim of this study was to evaluate the feasibility and values of FRI in children in relation to the values previously established in adults and comparing children with functional constipation and retentive fecal incontinence to children without retentive fecal incontinence. METHODS This retrospective study evaluated 105 ARM performed from Jan 2014 to Apr 2015. 42 patients were selected (were able to perform a voluntary contraction and had no co-morbidities other than functional constipation). 14 (33.3%) of those collaborated in sustaining contraction for 40 seconds (s), allowing the evaluation of the FRI. Patients with retentive fecal incontinence secondary to functional constipation (n=7, aged 6 to 13 years, six boys) were our interest group. Patients with functional constipation without fecal incontinence (n=7, aged 6 to 13 years, four boys) were considered a reference group. The ARM were performed with a radial eight-channel perfusion catheter (DynamedTM, São Paulo, Brazil) and the FRI was calculated (Proctomaster 6.4) in the first 20 s and overall 40 s of sustained voluntary contraction. RESULTS 14 of the selected 42 collaborated in sustaining contraction for 40 s, allowing the evaluation of the FRI. In the first 20 s of contraction, the fecal incontinence group showed a significantly higher mean FRI (2.48±1.39 min) compared to the reference group (1.13±0.72 min, P=0.042), which was not observed in the 40 s interval due to less uniform contraction. The anal resting pressure was higher in the fecal incontinence group (76.83 mmHg) than in the reference group (54.13 mmHg), but the statistical study did not reach significance (P=0.051). CONCLUSION The FRI is feasible in children. The mean FRI obtained in this study is lower than the reported in constipated adults. The mean FRI among children with functional constipation and retentive fecal incontinence is higher than among constipated children without retentive fecal incontinence.

Abstract
OBJECTIVE To describe the type of milk used to feed infants seen in private pediatric practices in Brazil. To evaluate the relationship between breastfeeding, type of delivery, and history of prematurity. METHODS This is a cross-sectional and observational study that included 4929 infants in the first year of life seen in private pediatric practices in the five geographic regions of Brazil. Mothers provided information about the type of milk used by their infant, the type of delivery (vaginal or cesarean), and whether the birth was premature. RESULTS Breastfeeding was the only source of milk for 56.1% (1546/2755) of infants in the first six months of life and 32.9% (716/2174) in the second. Of the infants who received other types of milk besides breastfeeding, there was a predominance of infant formula in 98.6% and 93.8% of the infants, respectively, in the first and in the second six months of life. Whole cow's milk was used by 0.7% (20/2755) of infants in the first six months and by 4.1% (90/2174) of infants in the second (p < 0.001). In the first six months of life, breastfeeding as the only type of milk was associated with vaginal delivery (OR = 1.79; p < 0.001) and not having a history of prematurity (OR = 2.48; p < 0.001). CONCLUSION Breastfeeding was the only milk source for more than half of infants before 180 days of life. Birth by cesarean section and history of prematurity were negatively associated with breastfeeding as the only source of milk used in infant feeding.

CLINICAL SPECTRUM OF FUNCTIONAL CONSTIPATION AND BOWEL-HABIT PATTERNS OF SCHOOLCHILDREN RECRUITED FROM TWO ELEMENTARY SCHOOLS AND A SPECIALIZED OUTPATIENT CLINIC. ARQUIVOS DE GASTROENTEROLOGIA 2022; 59:263-267. [PMID: 35830039 DOI: 10.1590/s0004-2803.202202000-47] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/05/2022] [Accepted: 03/24/2022] [Indexed: 06/15/2023]
Abstract
BACKGROUND Early diagnosis of functional constipation is important for reducing its negative consequences on the health of children and adolescents. OBJECTIVE To describe the clinical spectrum of functional constipation and bowel habit patterns in schoolchildren recruited from two primary schools and patients from a pediatric gastroenterology outpatient clinic. METHODS This cross-sectional study included 452 students from two elementary schools in the city of Osasco and 81 patients with functional constipation seen in an outpatient clinic specializing in pediatric gastroenterology. All children were aged between 6 and 12 years. The Rome IV criteria (two features for more than 1 month) and the Bristol scale were used. RESULTS The prevalence of functional constipation among the elementary school students was 22.3% (n=101). Among the 351 students who did not have functional constipation, 182 (51.9%) had one of the clinical manifestations of the Rome IV criteria. Bristol stool scale types 1 and 2 were observed in 14 (8.3%) of the 169 students without any clinical manifestation of the Rome IV criteria and in 28 (15.4%) of the 182 students who presented one of the Rome IV criteria for functional constipation (P=0.060). A comparison of the clinical manifestations of children with functional constipation identified at school in relation to those seen at the specialized clinic showed the following differences: fewer than two bowel movements per week (21.8% and 54.3%; P<0.001, respectively), one or more episodes of fecal incontinence per week (14.8% and 53.1%; P<0.001), and retentive posturing (70.3% and 40.7%, P<0.001). Only 18 (17.8%) of the 101 students identified at the schools with functional constipation had received any treatment for this disease in the previous 2 months. CONCLUSION As expected, the frequency of more severe clinical manifestations was higher in children seen at specialized clinics. Only a small proportion of the children identified with functional constipation at primary schools had undergone any form of treatment in the previous 2 months. More than half of the children without functional constipation in elementary schools reported one of the Rome IV clinical manifestations. Finally, functional constipation has a broad clinical spectrum and also requires attention for the prevention and the management of its early clinical manifestations.

Abstract
Resumo Objetivo: Avaliar a dieta e o estado nutricional de lactentes em dieta de exclusão das proteínas do leite de vaca. Métodos: Estudo observacional, transversal, que comparou: lactentes em dieta de exclusão das proteínas do leite de vaca (n=60) atendidos em unidade de dispensação de fórmulas hipoalergênicas e lactentes sem restrições alimentares (n=60), de mesma idade e sexo (grupo controle). A idade variou de seis a 24 meses. A dieta foi avaliada com o emprego do inquérito alimentar e foram mensurados o peso e a estatura. Resultados: A ingestão de macronutrientes foi adequada em ambos os grupos. No grupo em dieta de exclusão das proteínas do leite de vaca, as proporções de lactentes com ingestão insuficiente foram menores em relação aos controles, para ferro (13,3 e 31,7%; p=0,029), zinco (5,0 e 18,3%; p=0,047) e vitamina D (25,0 e 71,7%; p<0,001). A fórmula hipoalergênica contribuiu com maior oferta de nutrientes do que os alimentos lácteos para o grupo controle. Entre 12 e 24 meses, o número de lactentes em dieta de exclusão que nunca consumiram carne bovina, peixe, cereais e ovo foi maior do que no grupo controle (p<0,05). Os escores Z de comprimento-idade nos lactentes em dieta de exclusão das proteínas do leite de vaca (-0,4±1,6) foram menores (p=0,039) do que no grupo controle (+0,2±1,3). Conclusões: A dieta de lactentes em exclusão do leite de vaca foi adequada apesar do atraso na introdução de alguns alimentos. Lactentes em dieta de exclusão apresentaram menor crescimento linear não acompanhado de déficit ponderal.

Abstract
Objective: To evaluate the diet and nutritional status of infants on an elimination diet of cow’s milk proteins. Methods: Observational and cross-sectional study that compared: Infants on a cow’s milk protein elimination diet (n=60) assisted at a hypoallergenic formula distribution unit and a control group of same age and gender without dietary restrictions (n=60). Age ranged from 6 to 24 months. The diet was evaluated using the 24-hour food survey and weight and height were measured. Results: The macronutrient intake of both groups reached nutritional recommendations. The proportions of infants in the group of elimination of cow’s milk proteins with insufficient intake were lower, compared to controls, for iron (13.3 and 31.7%; p=0.029), zinc (5.0 and 18.3%; p=0.047), and vitamin D (25.0 and 71.7%; p<0.001). The hypoallergenic formula contributed to a greater supply of nutrients than dairy foods for the control group. Between 12 and 24 months, the number of infants on a restriction diet who never consumed meat, fish, cereals, and eggs was higher than in the control group (p<0.05). The length-age Z scores in infants on a cow’s milk protein elimination diet (-0.4±1.6) were lower (p=0.039) than in the control group (+0.2±1.3). Conclusions: The diet of infants with exclusion of cow’s milk protein was adequate despite the delay in the introduction of some complementary foods. Infants on an elimination cow’s milk protein diet showed lower linear growth without weight deficit.

Abstract
OBJECTIVES To evaluate the association between violence exposure, abuse, and neglect victimization with functional constipation and irritable bowel syndrome in adolescents. METHODS Observational cross-sectional case-control study conducted with adolescents from two public schools in the municipality of Osasco, metropolitan region of São Paulo, Brazil. A self-administered questionnaire validated for Brazilian Portuguese Child Abuse Screening Tools - Children's version (ICAST-C) was used to screen the different types of violence. The definition of functional constipation and irritable bowel syndrome was performed using the Rome IV criteria for adolescents. Parents or legal guardians completed the questionnaire for socioeconomic assessment and signed the informed consent form. RESULTS 265 students aged 11-17 years, 157 females, were evaluated. Functional constipation and irritable bowel syndrome were found in 74 (27.9%) of the 265 adolescents. Violence exposure was found in 82.6% of the 265 screened adolescents, physical abuse in 91.3%, psychological abuse in 93.2%, sexual abuse in 12.1%, and neglect in 53.6%. The multiple logistic regression analysis showed an association (p < .05) between functional constipation and irritable bowel syndrome with violence exposure (OR = 2.77), physical abuse (OR = 2.17), psychological abuse (OR = 2.95), and neglect (OR= 2.31). There was no association with sexual abuse. CONCLUSIONS Functional constipation and irritable bowel syndrome were associated with violence exposure, physical abuse, psychological abuse, and neglect in adolescent students from public schools. No association was found with sexual abuse. Further studies are necessary to investigate the causal relationship between violence and functional gastrointestinal disorders.

Abstract
BACKGROUND Increased intestinal permeability may be associated with certain disorders, such as obesity and small intestine bacterial overgrowth (SIBO). OBJECTIVE This study aimed to investigate intestinal permeability and SIBO in excess weight adolescents. METHODS This cross-sectional study included 67 adolescents with excess weight and 66 normal weight adolescents. Excess weight was defined as a body mass index for age (BMI/age) > +1 SD, which includes having excess body weight and obesity. SIBO was diagnosed by a breath test after the ingestion of lactulose according to the production of hydrogen and methane. Zonulin (haptoglobin) was considered an indicator of intestinal permeability. RESULTS Adolescents with excess weight had a higher height/age Z-score (median [25th; 75th percentile]: +0.6 [-0.4; +1.0]) than those in the normal weight group (-0.1 [-0.6; +0.7]; P = .014). Zonulin (mg/mL) in the excess weight (2.3 [1.5; 3.8]) adolescents was higher than that in the normal weight (1.6 [1.0; 2.2]) adolescents (P < .001). SIBO was diagnosed in 23.3% (31/133) of the adolescents. The adolescents with SIBO had a lower (P < .05) BMI/age (+0.6 [-0.6; +1.9]) and height/age (-0.3 [-0.7; +0.3]) than the adolescents without SIBO (+1.3 [+0.1; +2.6] and +0.2 [-0.5; +1.0], respectively). No association was found between zonulin and SIBO. CONCLUSION Excess weight is associated with increased intestinal permeability. No relationship was found between SIBO and intestinal permeability; however, SIBO was related to lower BMI and height for age Z-scores.

Abstract
Objectives: To assess the prevalence of functional constipation and its association with overweight, physical activity and the estimation of fat and fiber intake in adolescents.Methods: In all, 386 adolescents aged 14-19 years from the city of Maceió (Alagoas, Northeast Brazil) were included in this study. Participants responded to standardized questionnaires that assessed bowel habits, physical activity and the estimation of fat and dietary fiber intake. Functional constipation was defined according to the Rome criteria. Weight and height were measured using standard methods. Body mass index (BMI) was used to evaluate whether a participant was overweight.Results: The prevalence of constipation was 24.9%. The median BMI was higher in female adolescents with constipation (22.6) compared with female adolescents without constipation (20.0; p = .001). Physical inactivity (fewer than 300 min of physical activity per week) was more frequent in females (62.7%; 126/201) than in males (42.2%; 78/185; p = .000). No association was observed between physical inactivity and functional constipation. Excessive intake of fat in the diet was found in 45.3% (175/386) of participants, while poor dietary fiber intake was found in 84.2% (325/386) of participants. No association was found between a fat-rich diet and constipation. Low dietary fiber intake was associated with constipation in female adolescents (odds ratio = 3.42, 95% confidence interval: 1.08 and 12.06).Conclusions: The prevalence of constipation was high among this group of adolescents. Constipation was not associated with physical inactivity but was associated with a low dietary fiber intake and higher BMI values in female adolescents.

Abstract
BACKGROUND It is possible that imbalances in the composition of the gut microbiota or the relationship of the microbiota with the host may be implicated in the origin of allergy. Therefore, we studied the intestinal microbiota of children with atopic dermatitis (AD). METHODS Cross-sectional study with 81 children aged 5-11; 23 with AD and 58 controls. Surveys were conducted to obtain demographic, socioeconomic and neonatal data. Diagnosis of AD was made based on the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire. Eubacteria, Bacteroidetes, Firmicutes, B. fragilis, E. coli, Lactobacillus spp., S. aureus, E. faecalis, Salmonella spp., M. smithii, Bifidobacterium spp., C. difficile and C. perfringens were quantified using real-time PCR. RESULTS The analysis showed an association between presence of C. difficile (OR: 5.88; 95 % CI: 1.24; 27.98), greater abundance of bifidobacteria (OR: 11.09; 95 % CI: 2.14; 57.39) and a lower abundance of lactobacilli (OR: 0.07; 95 % CI: 0.01; 0.51) in the gut microbiota of children with AD. Counts of Eubacteria (0,05×103 and 8.49×103), B. fragilis (0.72×109 and 4.5×109), Lactobacillus spp. (0.02×108 and 0.38×108), E. coli (0.13×109 and 1.52×109) and M. smithii (0.02×108 and 0.31×108) were lower in children with AD (P<0.05). CONCLUSIONS This study confirmed that children living in the metropolitan area of São Paulo (Brazil) with AD have a different microbiota pattern with higher prevalence of C. difficile, lower abundance of Lactobacillus and greater abundance of bifidobacteria, regardless of socioeconomic status.

Brazilian pediatricians' adherence to food allergy guidelines-A cross-sectional study. PLoS One 2020; 15:e0229356. [PMID: 32092100 PMCID: PMC7039437 DOI: 10.1371/journal.pone.0229356] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/22/2019] [Accepted: 02/04/2020] [Indexed: 12/20/2022] Open
Abstract
Food allergy is an emerging clinical condition in pediatrics, so recommendations on its management have been widely published. Studying pediatricians' adherence to these clinical practice guidelines (CPG) and understanding the reasons for their non-compliance can help to promote better management of this condition. A cross-sectional study was conducted by a survey among Brazilian pediatricians, randomly selected during the 38th Brazilian Congress of Pediatrics, which took place in October, 2017. A validated questionnaire with 16 questions addressing knowledge and practice on food allergy, as well as self-reported adherence to international guidelines was applied. Of the total of 415 pediatricians from all regions of the country who were surveyed, only 69 (16.7%) had a satisfactory adherence rate (≥80%). Adequate adherence to the guidelines was associated with the variables: 'evaluating more than 10 children with suspected cow's milk allergy (CMA) per month'; 'having read the Brazilian consensus'; or 'being aware of any international food allergy guideline'. In 8 of the 10 questions that assessed conscious adherence, a minority of those surveyed (20.3-42.3% variation) stated that they knew that their response was in line with the guidelines. This finding was statistically significant (p<0.05) in 7 of these 8 questions. The self-reported adherence of Brazilian pediatricians to international food allergy guidelines was low. Pediatricians who evaluated a higher number of children with suspected CMA or who were aware of the recommendations, had a higher rate of adherence. The results of the survey found that lack of resource was the major reported barrier to guideline adherence but lack of awareness must be a relevant non perceived barrier. This study shows the pediatricians´ self-reported adherence to food allergy guidelines in a widely overview for the first time in Brazil. More studies are necessary to investigate adherence to guidelines by pediatricians in other countries and to develop strategies to improve adherence.

THE IMPACT OF SMALL INTESTINAL BACTERIAL OVERGROWTH ON THE GROWTH OF CHILDREN AND ADOLESCENTS. ACTA ACUST UNITED AC 2020; 38:e2018164. [PMID: 31939507 PMCID: PMC6958541 DOI: 10.1590/1984-0462/2020/38/2018164] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/08/2018] [Accepted: 09/11/2018] [Indexed: 01/15/2023]
Abstract
Objective: To evaluate the association between small intestinal bacterial overgrowth (SIBO) and weight and height impairment in children and adolescents with gastroenterology diseases. Methods: Observational and retrospective study. All 162 patients aged less than 19 years old who underwent breath test in search of SIBO between 2011 and 2016 were studied. Breath test was collected after the intake of 10 grams of lactulose. The concentration of hydrogen and methane was measured for 180 minutes after the beginning of the test by 12i QuinTronMicroLyzer device. Results: SIBO was identified in 51 (31.5%) patients. There was no difference between the age of those with (mean=8.7y.o; 25th and 75th percentile: 4.6 and 11.3) and without (mean=7.9y.o 25th and 75th percentile: 4.8 and 12.2) SIBO (p=0.910). There was no association between gender and SIBO (male 26.3% vs. female 36.3%, p=1.00). A lower median of height-for-age Z score (mean=-1.32; 25th and 75th percentile: -2.12 and -0.08 vs. mean=-0.59; 25th and 75th percentile: -1.57 and 0.22; p=0.04) was demonstrated in children with SIBO when compared with children without it. There was no difference between the BMI-for-age Z score of patients with (mean=-0.48) and without SIBO (mean=-0.06) (p=0.106). The BMI of patients with SIBO (median=15.39) was lower than of those without it (median=16.06); however, the statistical analysis was not significant (p=0.052). The weight-for-age Z score was lower in patients with SIBO (mean=-0.96) than in those without SIBO (mean=-0.22) (p=0.02) Conclusions: Children and adolescents with SBIO associated with diseases of the gastrointestinal tract have lower weight and height values.

Abstract
Recent studies have demonstrated that gut microbiota development is influenced by human biogeographic factors such as race, ethnicity, diet, lifestyle or culture-specific variations, and other environmental influences. However, biogeographic variation in gut microbiota assembly remains largely unexplored in Latin America. In this paper, we compared food recall information and microbiota composition of toddlers living in geographically separated urban populations within four states of Brazil. 16S RNA gene sequencing revealed that alpha diversity was similar between the four different populations. Gut microbiota compositions were dominated by members of the phyla Firmicutes and Bacteroidetes, resembling a more adult-like microbiota as compared with those of Western European toddlers of similar age. These findings suggest that inter-individual and nutrition-induced differences were apparent in the fecal microbiota. We conclude that urban dietary pattern plays a larger role in influencing the gut microbiota composition than do biogeographic factors.

GUT MICROBIOTA AND THE USE OF PROBIOTICS IN CONSTIPATION IN CHILDREN AND ADOLESCENTS: SYSTEMATIC REVIEW. ACTA ACUST UNITED AC 2019; 38:e2018123. [PMID: 31778407 PMCID: PMC6909257 DOI: 10.1590/1984-0462/2020/38/2018123] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2018] [Accepted: 08/30/2018] [Indexed: 12/12/2022]
Abstract
Objective: To perform a systematic review of literature data on gut microbiota and the efficacy of probiotics for the treatment of constipation in children and adolescents. Data source: The research was performed in the PubMed, the Scientific Electronic Library Online (SciELO) and the Latin American and Caribbean Health Sciences Literature (LILACS) databases in English, Portuguese and Spanish. All original articles that mentioned the evaluation of the gut microbiota or the use of probiotics in children with constipation in their title and abstract were selected. Data synthesis: 559 articles were found, 47 of which were selected for reading. From these, 12 articles were included; they studied children and adolescents divided into two categories: a gut microbiota evaluation (n=4) and an evaluation of the use of probiotics in constipation therapy (n=8). The four papers that analyzed fecal microbiota used different laboratory methodologies. No typical pattern of gut microbiota was found. Regarding treatment, eight clinical trials with heterogeneous methodologies were found. Fifteen strains of probiotics were evaluated and only one was analyzed in more than one article. Irregular beneficial effects of probiotics have been demonstrated in some manifestations of constipation (bowel frequency or consistency of stool or abdominal pain or pain during a bowel movement or flatulence). In one clinical trial, a complete control of constipation without the use of laxatives was obtained. Conclusions: There is no specific pattern of fecal microbiota abnormalities in constipation. Despite the probiotics’ positive effects on certain characteristics of the intestinal habitat, there is still no evidence to recommend it in the treatment of constipation in pediatrics.

Abstract
OBJECTIVE To assess the carotid intima-media thickness and factors associated with cardiovascular disease in children and adolescents with chronic kidney disease. MATERIAL AND METHODS Observational, cross-sectional study carried out at the Universidade Federal de São Paulo (chronic kidney disease outpatient clinics) with 55 patients (60% males) with a median age of 11.9 years (I25-I75: 9.2-14.8 years). Of the 55 patients, 43 were on conservative treatment and 12 were on dialysis. Serum laboratory parameters (creatinine, uric acid, C-reactive protein, total cholesterol and fractions, and triglycerides), nutritional status (z-score of body mass index, z-score of height/age), body fat (fat percentage and waist circumference), and blood pressure levels were evaluated. The carotid intima-media thickness measure was evaluated by a single ultrasonographer and compared with percentiles established according to gender and height. Data collection was performed between May 2015 and March 2016. RESULTS Of the children and adolescents with chronic kidney disease, 74.5% (95% CI: 61.0; 85.3) showed an increase (>P95) in carotid intima-media thickness. In patients with stages I and II hypertension, 90.9% had increased carotid intima-media thickness. Nutritional status, body fat and laboratory tests were not associated with increased carotid intima-media thickness. After multivariate adjustment, only puberty (PR=1.30, p=0.037) and stages I and II arterial hypertension (PR=1.42, p=0.011) were independently associated with carotid intima-media thickness alterations. CONCLUSION The prevalence of increased carotid thickness was high in children and adolescents with chronic kidney disease. Puberty and arterial hypertension were independently associated with increased carotid intima-media thickness.

Abstract
BACKGROUND Cerebral palsy may be associated with comorbidities such as undernutrition, impaired growth and gastrointestinal symptoms. Children with cerebral palsy exhibit eating problems due to the effect on the anatomical and functional structures involved in the eating function resulting in malnutrition. OBJECTIVE The aim of this study was to investigate the association between food intake, nutritional status and gastrointestinal symptoms in children with cerebral palsy. METHODS Cross-sectional study that included 40 children with cerebral palsy (35 with spastic tetraparetic form and 5 with non-spastic choreoathetoid form of cerebral palsy, all requiring wheelchairs or bedridden) aged from 4 to 10 years. The dietary assessment with the parents was performed using the usual household food intake inquiry. Anthropometric data were collected. Gastrointestinal symptoms associated with deglutition disorders, gastroesophageal reflux and chronic constipation were also recorded. RESULTS The median of height-for-age Z-score (-4.05) was lower (P<0.05) than the median of weight-for-age (-3.29) and weight-for-height (-0.94). There was no statistical difference between weight-for-age and weight-for-height Z-scores. Three patients with cerebral palsy (7.5%) exhibited mild anemia, with normal ferritin levels in two. Symptoms of dysphagia, gastroesophageal reflux, and constipation were found in 82.5% (n=33), 40.0% (n=16), and 60.0% (n=24) of the sample, respectively. The patients with symptoms of dysphagia exhibited lower daily energy (1280.2±454.8 Kcal vs 1890.3±847.1 Kcal, P=0.009), carbohydrate (median: 170.9 g vs 234.5 g, P=0.023) and fluid intake (483.1±294.9 mL vs 992.9±292.2 mL, P=0.001). The patients with symptoms of gastrointestinal reflux exhibited greater daily fluid intake (720.0±362.9 mL) than the patients without symptoms of gastroesophageal reflux (483.7±320.0 mL, P=0.042) and a greater height-for-age deficit (Z-score: -4.9±1.7 vs 3.7±1.5, P=0.033). The patients with symptoms of constipation exhibited lower daily dietary fiber (9.2±4.3 g vs 12.3±4.3 g, P=0.031) and fluid (456.5±283.1 mL vs 741.1±379.2 mL, P=0.013) intake. CONCLUSION Children with cerebral palsy exhibited wide variability in food intake which may partially account for their severe impaired growth and malnutrition. Symptoms of dysphagia, gastroesophageal reflux, and constipation are associated with different food intake patterns. Therefore, nutritional intervention should be tailored considering the gastrointestinal symptoms and nutritional status.

Abstract
OBJECTIVE To describe the current indicators of environmental enteric dysfunction and its association with linear growth deficit and the height-for-age anthropometric indicator. DATA SOURCES Narrative review with articles identified in PubMed and Scopus databases using combinations of the following words: environmental, enteric, dysfunction, enteropathy, and growth, as well as the authors' personal records. DATA SYNTHESIS In the last 15 years, new non-invasive markers have been investigated to characterize environmental enteric dysfunction; however, the best tests to be used have not yet been identified. There is evidence that, in environmental enteric dysfunction, a systemic inflammatory process may also occur as a consequence of increased intestinal permeability, in addition to intestinal mucosa abnormalities. Bacterial overgrowth in the small intestine and changes in fecal microbiota profile have also been identified. There is evidence indicating that environmental enteric dysfunction can impair not only full growth but also the neuropsychomotor development and response to orally administered vaccines. It is important to emphasize that the environmental enteric dysfunction is not a justification for not carrying out vaccination, which must follow the regular schedule. Another aspect to emphasize is the greater risk for those children who had height impairment in early childhood, possibly associated with environmental enteric dysfunction, to present overweight and obesity in adulthood when exposed to a high calorie diet, which has been called "triple burden." CONCLUSIONS According to the analyzed evidence, the control of environmental enteric dysfunction is very important for the full expression of growth, development, and vaccine response in the pediatric age group.

Abstract
Studies have shown the positive effects of prebiotics on the intestinal absorption of Ca and Fe. The present study evaluated the effect of fructo-oligosaccharide (FOS) supplementation in soya beverage (SB) on absorption mechanisms of Ca and Fe in recently weaned rats. Male Wistar rats were divided into four groups: lactose-free cows' milk (CM), lactose-free CM with FOS (0·8 g/100 ml) (CMF), SB and soya beverage with FOS (0·8 g/100 ml) (SBF). These rats were euthanised after 1 week of treatment. Organ weight, pH of the caecal content and absorption mechanisms of Ca and Fe were evaluated. The results showed that the weight of the caecal contents increased in the CMF and SBF groups, and the pH of the caecal contents was lower in these groups. The Hb levels of the CMF and SB groups were higher when compared with that of the CM group and lower in relation to the SBF group. The apparent Ca and Fe absorption and apparent Ca retention in the CM group were higher when compared with the SB group, whereas in the CMF group, they were higher in relation to the SBF group. Divalent metal transporter 1 (DMT1) protein expression in the duodenum was higher in the SBF group than in the SB and CMF groups. SB resulted in lower intestinal Ca absorption and higher Hb concentration, despite the lower apparent Fe absorption in relation to CM. Supplementation with FOS provided beneficial effects on Hb and DMT1 protein expression in the duodenum, in addition to improving the absorption process.

Abstract
OBJECTIVE To study fructose malabsorption in children and adolescents with abdominal pain associated with functional gastrointestinal disorders. As an additional objective, the association between intestinal fructose malabsorption and food intake, including the estimated fructose consumption, weight, height, and lactulose fermentability were also studied. METHODS The study included 31 patients with abdominal pain (11 with functional dyspepsia, 10 with irritable bowel syndrome, and 10 with functional abdominal pain). The hydrogen breath test was used to investigate fructose malabsorption and lactulose fermentation in the intestinal lumen. Food consumption was assessed by food registry. Weight and height were measured. RESULTS Fructose malabsorption was characterized in 21 (67.7%) patients (nine with irritable bowel syndrome, seven with functional abdominal pain, and five with functional dyspepsia). Intolerance after fructose administration was observed in six (28.6%) of the 21 patients with fructose malabsorption. Fructose malabsorption was associated with higher (p<0.05) hydrogen production after lactulose ingestion, higher (p<0.05) energy and carbohydrate consumption, and higher (p<0.05) body mass index z-score value for age. Median estimates of daily fructose intake by patients with and without fructose malabsorption were, respectively, 16.1 and 10.5g/day (p=0.087). CONCLUSION Fructose malabsorption is associated with increased lactulose fermentability in the intestinal lumen. Body mass index was higher in patients with fructose malabsorption.

Abstract
BACKGROUND Acceptance of the prevailing pediatric Rome constipation criteria, by primary care physician, is still low. Even for research purposes they have not been universally adopted. Thus, it has been indicated that some re-evaluation of these criteria would be welcome. OBJECTIVE The authors aimed to look at the timing of diagnosis and the dietary treatment recommendations in the criteria, to make proposals trying to approximate them to everyday practice. METHODS The literature cited in the Rome criteria was reviewed and the publications pertinent to the subject, searched by Medline up to January 2018, were included. RESULTS An early diagnosis is fundamental to avoid evolution to bothersome complications and possibly to 'intractable' constipation, but the inclusion of two items of the criteria might hamper it. Thus, one constipation sign/symptom should suffice, usually the easily observable 'painful or hard bowel movements'. Details about dietary fiber recommendations are missing in the criteria, although its increase is usually the first approach in primary care, and overall the data about dietary fiber supplements point to beneficial effects. CONCLUSION For diagnosis and treatment of pediatric constipation in primary care, one constipation sign/symptom should suffice. The recommended daily dietary fiber intake, according to the American Health Foundation, should be detailed as a treatment measure, and also for prevention, from weaning on.

Abstract
OBJECTIVE To analyze the fecal microbiota composition of children living in an urban slum in Brazil, with or without small intestinal bacterial overgrowth, and to investigate the occurrence of stunting and anemia. METHODS A total of 100 children were studied, aged 5-11 years, from the municipality of Osasco, São Paulo. Small intestinal bacterial overgrowth was screened through hydrogen and methane breath test with lactulose. Weight and height were measured, and the height-for-age and body mass-for-age anthropometric indexes were calculated. The occurrence of anemia was investigated by capillary hemoglobin. Analysis of bacterial phylum, genus, and species was performed by real-time polymerase chain reaction in fecal samples. RESULTS Small intestinal bacterial overgrowth was identified in 61.0% of the children. A lower mean of height-for-age Z-score ([-0.48±0.90] vs. [-0.11±0.97]; p=0.027), as well as capillary hemoglobin ([12.61±1.03g/dL] vs. [13.44±1.19g/dL]; p<0.001) was demonstrated in children with SIBO when compared with children without small intestinal bacterial overgrowth. Children with small intestinal bacterial overgrowth presented a higher frequency of Salmonella spp., when compared to those without small intestinal bacterial overgrowth (37.7% vs. 10.3%; p=0.002). Higher counts of total Eubacteria (p=0.014) and Firmicutes (p=0.038) were observed in children without small intestinal bacterial overgrowth; however, a higher count of Salmonella (p=0.002) was found in children with small intestinal bacterial overgrowth. CONCLUSION Children who lived in a slum and were diagnosed with small intestinal bacterial overgrowth showed lower H/A Z-scores and hemoglobin levels. Furthermore, differences were observed in the fecal microbiota of children with small intestinal bacterial overgrowth, when compared to those without it; specifically, a higher frequency and count of Salmonella, and lower counts of Firmicutes and total Eubacteria.

Abstract
Objective: To analyze the relationship between habits and attitudes of mothers and the types of milk offered to their children in their first two years of life. Methods: Retrospective study including 773 interviews of mothers from 11 Brazilian cities with children under 2 years of age. Interviews were conducted in 11 cities of Brazil. The following factors were analyzed: breastfeeding method planned during pregnancy and the method actually applied after birth; type(s) of milk(s) used on the day of the interview and earlier; age at which the child was introduced to whole milk; and source of advice used to choose a certain type of milk. Results: Breast milk was offered to 81.7% of infants during their first six months of life, to 52.2% of infants during their second semester (p<0.001) and to 32.9% of infants during their second year of life (p<0.001). In contrast, cow’s milk consumption increased from 31.1 to 83.8% (p<0.001) and 98.7% (p=0.05), respectively, for these three age groups. Infant (15.0%) and follow-on (also known as toddler’s) (2.3%) formulas were used by a much smaller number of infants than whole cow’s milk. Most mothers were not prescribed whole cow’s milk. Pediatricians were the health care professionals who most often recommended infant formulas. Conclusions: Rates of breastfeeding in Brazil remain below recommended levels. Brazilian mothers often decide to feed their infants with whole cow’s milk on their own initiative. The use of infant formulas after weaning is still too low.

[PMID: 28450053 DOI: 10.1016/j.jped.2017.01.005] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.9] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/18/2016] [Revised: 12/23/2016] [Accepted: 01/02/2017] [Indexed: 12/13/2022] Open
Abstract
OBJECTIVE To study the evidence on the role of water and fluid intake in the prevention and treatment of functional intestinal constipation in children and adolescents. SOURCE OF DATA A search was carried out in the Medline database (between 1966 and 2016) for all published articles containing the following words: constipation, water, and fluids, published in Portuguese, English, and Spanish. All original articles that assessed children and adolescents were selected by title and abstract. The references of these articles were also evaluated. SYNTHESIS OF DATA A total of 1040 articles were retrieved. Of these, 24 were selected for reading. The study included 11 articles that assessed children and adolescents. The articles were divided into two categories, those that evaluated water and fluid intake as a risk factor for intestinal constipation and those that evaluated their role in the treatment of intestinal constipation. Five articles were included in the first category. The criteria for assessing fluid intake and bowel rhythm were different in each study. Three studies demonstrated an association between low fluid intake and intestinal constipation. Regarding treatment, five articles with heterogeneous methodologies were found. None of them clearly identified the favorable role of fluid intake in the treatment of intestinal constipation. CONCLUSION There are few articles on the association between fluid intake and intestinal constipation. Epidemiological evidence indicates an association between lower fluid intake and intestinal constipation. Further clinical trials and epidemiological studies that consider the international recommendations for fluid intake by children and adolescents are required.

Abstract
BACKGROUND - Bowel function is a widely evaluated parameter in interventional and longitudinal studies since it is associated with good maintenance of health. The evaluation of intestinal function has been performed by many questionnaires, however, there are few options validated in Brazilian Portuguese. OBJECTIVE - The aim of this work was to translate and validate into Brazilian Portuguese the Gastrointestinal Symptom Rating Scale (GSRS) questionnaire. METHODS - Translation and cultural adaptation were performed according to a previously established methodology followed by reliability calculations. RESULTS - The final translated GSRS questionnaire showed an adequate value of overall reliability of Cronbach's alpha of 0.83, and its domains were classified from acceptable to adequate. The overall test-retest reliability by intraclass correlation coefficient (ICC) was 0.84, considered excellent. CONCLUSION - The GSRS was translated and validated into Brazilian Portuguese, with appropriate internal consistency and reliability and is available to be used in assessments of bowel function.

Abstract
AIMS To estimate the cost-effectiveness of a new strategy that uses an amino acid formula in the elimination diet of infants with suspected cow's milk allergy (CMA). MATERIALS AND METHODS This pharmacoeconomic study was developed from the perspective of the Brazilian Public Healthcare System. The new strategy proposes using an amino acid formula in the diagnostic elimination diet of infants (≤24 months) with suspected CMA. The rationale is that infants who do not respond to the amino acid formula do not suffer from CMA. Patients with a positive oral challenge test receive a therapeutic elimination diet based on Brazilian Food Allergy Guidelines. This approach was compared to the current recommendations of the Brazilian Food Allergy Guidelines. A decision model was constructed using TreeAge Pro 2012 software. Model inputs were based on a literature review and the opinions of a panel of experts. A univariate sensitivity analysis of incremental cost-effectiveness ratios was performed. RESULTS The mean cost per patient of the new amino acid formula strategy was R$3,341.57, while the cost of the current Brazilian guidelines strategy was R$3,641.08. The mean number of symptom-free days per patient, which was used as an indicator of effectiveness, was 900.6 and 875.7 days, respectively. The new strategy is, therefore, dominant. In the sensitivity analysis, the dominance was maintained with parameter variation. LIMITATIONS In the absence of information in the literature, some premises were defined by a panel of specialists. CONCLUSIONS The new strategy, which uses an amino acid formula in the elimination diagnostic diet followed by an oral food challenge, is a dominant pharmacoeconomic approach that has a lower cost and results in an increased number of symptom-free days.

Abstract
OBJECTIVE To compare body growth, weight, and fecal moisture in recently weaned rats fed exclusively on infant soy formula and soy-based beverage. METHODS Three similar groups were formed (n=10/group) consisting of weanling Wistar rats, maintained in metabolic cages. One group was fed soy protein-based beverage, another with soy-based infant formula, and another with cow's milk infant formula (control group). Water and diet were offered ad libitum. Body weight and length were measured. Stool was collected for three consecutive days. RESULTS Weight and length were lower (p = 0.001; p = 0.001) in the groups receiving soy protein-based beverage (73.16 ± 5.74 g; 23.94 ± 1.04 cm) and soy-based formula (71.11 ± 5.84 g; 24.74 ± 0.60 cm) in relation to the group receiving cow's milk formula (84.88 ± 9.75 g; 26.01 ± 0.91 cm). Fresh fecal weight was greater (p < 0.001) in the soy-based beverage (3.44 ± 0.48 g) than in the soy-based formula (0.79 ± 0.20 g) and cow's milk-based formula (0.42 ± 0.17 g). Fecal moisture was higher (p < 0.001) in the group receiving soy protein-based beverage (47.28 ± 9.02%) and soy-based formula (37.21 ± 13.20%) than in the group receiving cow's milk formula (22.71 ± 10.86%). CONCLUSION The growth of rats fed soy protein-based beverage and soy-based formula was lower than those fed cow's milk-based formula. The soy protein-based beverage resulted in significant increase in fecal weight and moisture.

Abstract
OBJECTIVE To assess the knowledge and practice of pediatricians about infants with physiological reflux and gastroesophageal reflux disease. METHODS 140 pediatricians were interviewed during two scientific events in 2009 and 2010. The questions referred to two clinical cases of infants. One with symptoms of infant regurgitation (physiological reflux) and another with gastroesophageal reflux disease. RESULTS Among 140 pediatricians, 11.4% (n=16) and 62.1% (n=87) would require investigation tests, respectively for infant regurgitation (physiological reflux) and gastroesophageal reflux disease. A series of upper gastrointestinal exams would be the first requested with a higher frequency. Medication would be prescribed by 18.6% (n=26) in the case of physiological reflux and 87.1% (n=122) in the case of gastroesophageal reflux disease. Prokinetic drugs would be prescribed more frequently than gastric acid secretion inhibitors. Sleeping position would be recommended by 94.2% (n=132) and 92.9% (n=130) of the respondents, respectively for the case of physiological reflux and gastroesophageal reflux disease; however, about half of the respondents would recommend the prone position. Only 10 (7.1%) of the pediatricians would exclude the cow's milk protein from the infants' diet. CONCLUSIONS Approaches different from the international guidelines are often considered appropriate, especially when recommending a different position other than the supine and prescription of medication. In turn, the interviews enable us to infer the right capacity of the pediatricians to distinguish physiologic reflux and gastroesophageal reflux disease correctly.

Abstract
OBJECTIVE: To evaluate the attitude, the practice and the knowledge of pediatricians
regarding the management of the infant who cries excessively in the first months
of life. METHODS: Descriptive cross-sectional study that enrolled pediatricians (n=132) randomly
interviewed at a Pediatric meeting in Brazil, in August 2012. The data were
collected by a self-administered standardized form after reading the hypothetical
case of an infant who cried excessively. RESULTS: The majority of the participants were females, the mean age was 39 years and the
average mean time working in the specialty was 14 years; 52.2% were Board
Certified by the Brazilian Society of Pediatrics. The diagnosis most often
considered was gastroesophageal reflux disease (62.9%), followed by infant colic
(23.5%) and cow's milk allergy (6.8%). The diagnostic test most frequently
mentioned was 24-hour esophageal pH-monitoring (21.9%). The medications most
frequently indicated were domperidone (30.3%), the combination of domperidone with
ranitidine (12.1%) and paracetamol (6%). CONCLUSIONS: In the approach of the infant who cries excessively, diagnostic tests are
frequently requested and unnecessary medical treatment is usually recommended.

Abstract
OBJECTIVES To determine whether antibiotic treatment leads to improvements in growth in prepubertal children in low and middle income countries, to determine the magnitude of improvements in growth, and to identify moderators of this treatment effect. DESIGN Systematic review and meta-analysis. DATA SOURCES Medline, Embase, Scopus, the Cochrane central register of controlled trials, and Web of Science. STUDY SELECTION Randomised controlled trials conducted in low or middle income countries in which an orally administered antibacterial agent was allocated by randomisation or minimisation and growth was measured as an outcome. Participants aged 1 month to 12 years were included. Control was placebo or non-antimicrobial intervention. RESULTS Data were pooled from 10 randomised controlled trials representing 4316 children, across a variety of antibiotics, indications for treatment, treatment regimens, and countries. In random effects models, antibiotic use increased height by 0.04 cm/month (95% confidence interval 0.00 to 0.07) and weight by 23.8 g/month (95% confidence interval 4.3 to 43.3). After adjusting for age, effects on height were larger in younger populations and effects on weight were larger in African studies compared with other regions. CONCLUSION Antibiotics have a growth promoting effect in prepubertal children in low and middle income countries. This effect was more pronounced for ponderal than for linear growth. The antibiotic growth promoting effect may be mediated by treatment of clinical or subclinical infections or possibly by modulation of the intestinal microbiota. Better definition of the mechanisms underlying this effect will be important to inform optimal and safe approaches to achieving healthy growth in vulnerable populations.

Abstract
OBJECTIVE there are many questions and little evidence regarding the diagnosis and treatment of gastroesophageal reflux disease (GERD) in children. The association between GERD and cow's milk protein allergy (CMPA), overuse of abdominal ultrasonography for the diagnosis of GERD, and excessive pharmacological treatment, especially proton-pump inhibitors (PPIs) are some aspects that need clarification. This review aimed to establish the current scientific evidence for the diagnosis and treatment of GERD in children. DATA SOURCE a search was conducted in the MEDLINE, PubMed, LILACS, SciELO, and Cochrane Library electronic databases, using the following keywords: gastroesophageal reflux; gastroesophageal reflux disease; proton-pump inhibitors; and prokinetics; in different age groups of the pediatric age range; up to May of 2013. DATA SYNTHESIS abdominal ultrasonography should not be recommended to investigate gastroesophageal reflux (GER). Simultaneous treatment of GERD and CMPA often results in unnecessary use of medication or elimination diet. There is insufficient evidence for the prescription of prokinetics to all patients with GER/GERD. There is little evidence to support acid suppression in the first year of life, to treat nonspecific symptoms suggestive of GERD. Conservative treatment has many benefits and with low cost and no side-effects. CONCLUSIONS there have been few randomized controlled trials that assessed the management of GERD in children and no examination can be considered the gold standard for GERD diagnosis. For these reasons, there are exaggerations in the diagnosis and treatment of this disease, which need to be corrected.

Abstract
OBJECTIVE To review the literature for clinical data on infants with allergic or eosinophilic colitis. DATA SOURCE MEDLINE search of all indexes was performed using the words "colitis or proctocolitis and eosinophilic" or "colitis or proctocolitis and allergic" between 1966 and February of 2013. All articles that described patients' characteristics were selected. DATA SYNTHESIS A total of 770 articles were identified, of which 32 met the inclusion criteria. The 32 articles included a total of 314 infants. According to the available information, 61.6% of infants were male and 78.6% were younger than 6 months. Of the 314 patients, 49.0% were fed exclusively breast milk, 44.2% received cow's milk protein, and 6.8% received soy protein. Diarrheal stools were described in 28.3% of patients. Eosinophilia was found in 43.8% (115/263) of infants. Colonic or rectal biopsy showed infiltration by eosinophils (between 5 and 25 per high-power field) in 89.3% (236/264) of patients. Most patients showed improvement with the removal of the protein in cow's milk from their diet or the mother's diet. Allergy challenge tests with cow's milk protein were cited by 12 of the 32 articles (66 patients). CONCLUSIONS Eosinophilic colitis occurs predominantly in the first six months of life and in males. Allergy to cow's milk was considered the main cause of eosinophilic colitis. Exclusion of cow's milk from the diet of the lactating mother or from the infant's diet is generally an effective therapeutic measure.

Abstract
Fifty-four and fifty samples of home-prepared feeding bottles for infants from a public health unit (low socioeconomic group, LSG) and from a private pediatric clinic (high socioeconomic group, HSG), respectively, were chemically analyzed, and their energy, macronutrient and iron contents were compared with the standard composition recommended for follow-up formulas. Cow's milk and sucrose and cereals added to the bottles were largely used in the study. Energy, protein and carbohydrate contents were higher than the recommended level in 75.9, 27.7 and 81.5% of LSG samples and 62.0, 48.0 and 34.0% of HSG samples, respectively. Fat content was lower than the recommended level in 83.3% of LSG and 58.0% of HSG samples. Excessive values of energy, carbohydrates and protein, low fat content and macronutrient imbalance were found regardless of the socioeconomic class, thus indicating the need to improve the domestic feeding bottles' preparation practices and discourage the use of cow's milk and the addition of other ingredients.

Abstract
OBJETIVO: Avaliar o estado nutricional e a ingestão de energia e de macronutrientes de pacientes com diagnóstico de doença celíaca que transgrediam ou não a dieta isenta de glúten. MÉTODOS: Foram estudados 63 pacientes com doença celíaca: 34 crianças e 29 adolescentes. Transgressão à dieta isenta de glúten foi caracterizada por meio da dosagem sérica do anticorpo antitransglutaminase tissular recombiante humana. O estado nutricional foi avaliado com base nos escores-Z de peso/idade, estatura/idade e no índice de massa corporal. A ingestão alimentar foi avaliada por meio do inquérito alimentar de 24 horas. RESULTADOS: A transgressão à dieta sem glúten foi constatada em 41,2% das crianças e em 34,5% dos adolescentes. Nas crianças com transgressão alimentar, a média do escore-Z de estatura/idade foi inferior à das crianças do grupo que não transgredia (p=0,024). Todavia, o grupo com transgressão apresentou maior escore-Z do índice de massa corporal em relação aos que não transgrediam (p=0,021). Os adolescentes que não transgrediam apresentaram maior índice de massa corporal quando comparados aos que transgrediam a dieta (p=0,037). Em relação à ingestão alimentar, não se observou diferença estatística entre os grupos. Todavia, cerca de 70,0% das crianças e adolescentes apresentaram consumo de energia acima de 120,0% da recomendação. CONCLUSÃO: As crianças que transgrediam a dieta apresentaram menor escore-Z de estatura/idade e maior escore-Z para índice de massa corporal do que crianças que seguem sem transgressões alimentares. Os adolescentes que não transgrediam a dieta apresentaram maior média de índice de massa corporal quando comparados aos que transgrediam a dieta. Consumo energético elevado foi observado tanto nas crianças quanto nos adolescentes.

Abstract
This study investigated the occurrence of Escherichia coli, an indicator of fecal contamination, in saliva samples from 141 children up to 36 months old, 53 not attending and 88 attending a child daycare center after exposure to a public daycare center and home environments. Two samples from each child were collected on the same day at 07:00 and 15:00 h and plated on MacConkey agar for identification. Samples E. coli negative in the morning and positive in the afternoon were statistically associated with the condition of the child attending daycare center (Odds ratio = 2.72; 95% confidence interval = 1.15/6.46). Exposure to the daycare center environment favored the potential risk of transmission of enteropathogens, as demonstrated by the presence of E. coli in saliva. The method proved to be easy to sample, non-invasive and feasible in young children. The findings suggest a novel and potentially valuable exposure measure.

Abstract
AIM To analyze small intestinal bacterial overgrowth in school-aged children and the relationship between hydrogen and methane production in breath tests. METHODS This transversal study included 85 children residing in a slum and 43 children from a private school, all aged between 6 and 10 years, in Osasco, Brazil. For characterization of the groups, data regarding the socioeconomic status and basic housing sanitary conditions were collected. Anthropometric data was obtained in children from both groups. All children completed the hydrogen (H(2)) and methane (CH(4)) breath test in order to assess small intestinal bacterial overgrowth (SIBO). SIBO was diagnosed when there was an increase in H(2) ≥ 20 ppm or CH(4) ≥ 10 ppm with regard to the fasting value until 60 min after lactulose ingestion. RESULTS Children from the slum group had worse living conditions and lower nutritional indices than children from the private school. SIBO was found in 30.9% (26/84) of the children from the slum group and in 2.4% (1/41) from the private school group (P = 0.0007). Greater hydrogen production in the small intestine was observed in children from the slum group when compared to children from the private school (P = 0.007). A higher concentration of hydrogen in the small intestine (P < 0.001) and in the colon (P < 0.001) was observed among the children from the slum group with SIBO when compared to children from the slum group without SIBO. Methane production was observed in 63.1% (53/84) of the children from the slum group and in 19.5% (8/41) of the children from the private school group (P < 0.0001). Methane production was observed in 38/58 (65.5%) of the children without SIBO and in 15/26 (57.7%) of the children with SIBO from the slum. Colonic production of hydrogen was lower in methane-producing children (P = 0.017). CONCLUSION Children who live in inadequate environmental conditions are at risk of bacterial overgrowth and methane production. Hydrogen is a substrate for methane production in the colon.

Abstract
BACKGROUND & AIMS To evaluate the knowledge and practice of pediatricians, pediatric gastroenterologists, allergists and nutritionists regarding the primary prevention of food allergy. METHODS A descriptive, cross-sectional study that enrolled pediatricians (n = 80), pediatric gastroenterologists (n = 120), allergists (n = 100) and nutritionists (n = 220). A self-administered questionnaire concerning the current recommendations was used. RESULTS Despite the lack of current recommendations, 17.1% (n = 89) of all professionals, mainly nutritionists, recommended a maternal exclusion diet during pregnancy. More professionals in the sample group, 40.8% (n = 212), recommended a maternal exclusion diet during breastfeeding, and the rates of recommendation were higher in nutritionists and pediatricians compared to allergists and pediatric gastroenterologists (p < 0.001). Regarding the recommended timing of the introduction of complementary feeding, 41.9% (n = 218) of the professionals recommended modifying the age of introduction to prevent the development of food allergy. The majority of the professionals believed that prebiotics (61.2%; n = 318) and probiotics (44.4%; 231) prevent the development of food allergy. The recommended age of introduction for the main allergenic foods was 12 months. CONCLUSIONS This study revealed that there are gaps in the knowledge of professionals about the primary prevention of food allergy.

Abstract
OBJECTIVES To compare three radiological scores in the study of fecal impaction in children with constipation. To investigate whether these radiological scores are useful in the assessment of fecal disimpaction therapy and if they present a relation with total colonic transit time. METHODS The Barr, Blethyn and Leech scores were measured by three observers, independently, in 123 abdominal radiographs. Interobserver agreement in the diagnosis of fecal impaction was calculated for the three scores. In 30 radiographs, the analysis of the scores was performed before and after fecal disimpaction. Total colonic transit time was calculated in 59 radiographs with the use of radiopaque markers. RESULTS The agreement between pairs of observers was assessed by the kappa coefficient and was good for the Barr (0.56, 0.59 and 0.69) and Leech scores (0.53, 0.58 and 0.61). The Blethyn score presented lower kappa coefficients (0.26, 0.32 and 0.36). In the comparison of methods, Leech and Barr showed a good correlation. After fecal disimpaction, there was a statistically significant reduction (p < 0.001) of scores, most significantly with the Barr score. There was no relation between radiographic scores and colonic transit time. CONCLUSIONS There is no relation between fecal impaction assessed by radiography of the abdomen and total colonic transit time. Plain radiographs may be a useful tool for the diagnosis of fecal impaction. The Barr score can be considered a good method of analysis, especially to assess the response to treatment of fecal impaction.

Abstract
OBJETIVO: Avaliar a prevalência de parasitoses intestinais, correlacionando-as com os fatores socioeconômicos e ambientais, peso, estatura e hemoglobina, em crianças de dois estratos socioeconômicos, no município de Osasco (SP). MÉTODOS: Estudo transversal, comparando 84 crianças de seis a dez anos, residentes em área sem saneamento básico e moradia precária, com 35 crianças de escola particular no mesmo município, que possuíam boas condições socioeconômicas e de moradia. Excluíram-se aquelas com diarreia há menos de 30 dias ou doença grave. Utilizou-se questionário padronizado para avaliar as condições socioambientais. A avaliação nutricional foi realizada mediante escores Z de peso para idade, estatura para idade e índice de massa corpórea. A determinação da hemoglobina em amostra de sangue capilar foi realizada pelo método Hemocue® e a pesquisa de parasitas intestinais, pelos métodos de Hoffman, Ritchie, Kinyoun e swab anal. RESULTADOS: Parasitose intestinal ocorreu em 60,7% das crianças da favela e em 5,9% das crianças da escola particular (p<0,001; OR 24,7). A média dos escores Z de peso para idade, estatura para idade e índice de massa corpórea foi menor nas crianças parasitadas (-0,78±0,84; +0,50±0,90; -0,76±0,96) em relação àquelas não parasitadas (-0,18±1,18; +0,03±1,10; -0,28±1,16), sendo as diferenças estatisticamente significantes (p<0,05). Não houve diferença nos valores médios de hemoglobina entre as crianças parasitadas e não parasitadas do grupo da favela (12,6±1,1g/dL e 12,8±1,2g/dL); p=0,58. CONCLUSÕES: A parasitose intestinal foi mais prevalente em crianças da favela e se associou a menores índices de peso e de estatura.
