Transcutaneous Posterior Tibial Nerve Stimulation: An Adjuvant Treatment for Intractable Constipation in Children.

BACKGROUND: Functional constipation can lead to painful defecations, fecal incontinence, and abdominal pain, significantly affecting a child's quality of life. Treatment options include non-pharmacological and pharmacological approaches, but some cases are intractable and require alternative interventions like neuromodulation. A subtype of neuromodulation, called Transcutaneous Posterior Tibial Nerve Stimulation (TPTNS), comprises electrical stimulation at the ankle level, by means of electrodes fixed to the skin. TPTNS is a minimally invasive, easy-to-apply technique that can potentially improve constipation symptoms in the pediatric population by stimulating the sacral nerves. AIM: To evaluate the clinical results and applicability of TPTNS as an adjuvant treatment for children and adolescents with functional constipation. METHODS: Between April 2019 and October 2021, 36 patients diagnosed with functional constipation according to the Rome IV Criteria were invited to participate in the study. The study followed a single-center, uncontrolled, prospective cohort design. Patients received TPTNS for 4 or 8 weeks, with assessments conducted immediately after the periods of TPTNS and 4 weeks after the end of the intervention period. The data normality distribution was determined by the Shapiro-Wilk test. The Wilcoxon test and Student's t-test for paired samples were used to compare quantitative variables, and the McNemar test was used to compare categorical variables. RESULTS: Of the 36 enrolled patients, 28 children and adolescents with intractable function constipation completed the study, receiving TPTNS for 4 weeks. Sixteen patients (57.1%) extended the intervention period for 4 extra weeks, receiving 8 weeks of intervention. TPTNS led to significant improvements in stool consistency, frequency of defecation, and bowel function scores, with a reduction in abdominal pain. Quality of life across physical and psychosocial domains showed substantial enhancements. The quality of life-related to bowel habits also improved significantly, particularly in lifestyle, behavior, and embarrassment domains. The positive effects of this intervention are seen relatively early, detected after 4 weeks of intervention, and even 4 weeks after the end of the intervention. TPTNS was well-tolerated, with an adherence rate of approximately 78%, and no adverse effects were reported. CONCLUSIONS: TPTNS is an adjuvant treatment for intractable functional constipation, improving bowel function and quality of life. The effects of TPTNS were observed relatively early and sustained even after treatment cessation.

Labeling food allergens in the packaged food pyramid groups in Brazil: analysis of descriptions, ambiguities, and risks.

OBJECTIVE: The aim of this study was to evaluate allergenic labeling components of packaged foods for "What is the quality of food labels?" and "What is the group of Brazilian Food Pyramid that 'May contain' is predominant?." METHODS: The photographs of 916 products were obtained, of which 518 were analyzed. Data from each label were evaluated according to Brazilian Food Pyramid Groups (i.e., Cereals, Fruits, & Vegetables; Soybean & products; Milk & dairy products; Meat & eggs; Fats & oils; and Sugars & sweets). Ten items were analyzed in each label, namely, the presence of a list of ingredients, alert phrase for allergy sufferers, grouping of the alert phrase, phrase location, uppercase phrase, the phrase in bold, the color of alert phrase contrasting to the background, adequate font size, do not claim the absence for any allergen with the ingredients, and others factors that make it difficult to read. For the second question, a structured questionnaire was completed, and products were classified into two categories, namely, "Contain" and "May contain." RESULTS: The quality of the label was appropriate, and 69% of packaged foods had at least one allergen. The information "May contain" were higher in cow's milk (Cereals and Meat & eggs), soy (Soybean & products), and egg protein (Cereals). Soybean & products were the highest insecurity group. CONCLUSIONS: Brazilian health professionals can count on good-quality labeling of packaged products. Consequently, they could promote patients' and parents/caregivers' education to consult the labels and manage the risks in processed foods about precautionary allergen labeling. Soybean & products were the most significant insecurity for food choices between Brazilian Pyramid Groups.

Pediatric Functional Constipation Questionnaire-Parent Report (PedFCQuest-PR): development and validation

Abstract Objective: Developing and validating a disease-specific instrument in the Brazilian Portuguese language to assess the Health-Related Quality of Life of children with functional constipation, applied to parents/caregivers. Methods: The process of developing the questionnaire was carried out in the following steps: items generation concerning functional constipation; elaboration of the preliminary questionnaire; assessment by health professionals; identifying problems or inconsistencies by the researchers; improvement of the questions; obtaining a final questionnaire named Pediatric Functional Constipation Questionnaire-Parent Form (PedFCQuest-PR) with 26 questions divided into four domains. Responses options use a Likert scale based on the events of the last four weeks. The process of validation was an observational, cross-sectional study in a sample of 87 parents/caregivers of children from 5 to 15 years of age diagnosed with Functional constipation according to the Rome IV Criteria. The questionnaire was applied simultaneously to the Pediatric Quality of Life Inventory 4.0 (PedsQL TM 4.0) as a control. Results: The questionnaire validation included 87 parents/caregivers. The children's median age was 8.2 years, with a long time of constipation symptoms associated with fecal incontinence in approximately two-thirds. Internal consistency reliability for the Total Scale Score of PedFC-Quest-PR by Coefficient Alpha of Cronbach score was 0.86. Convergent and divergent validity of PedFCQuest-PR was demonstrated by correlating the domains of both questionnaires. Conclusion: This study provides evidence that PedFCQuest-PR is a reliable instrument. The results showed a high degree of internal consistency and validity of the instrument for future applications.

RESUMO Objetivo: Avaliar os componentes alergênicos da rotulagem de alimentos embalados e responder "Qual é a qualidade da rotulagem?" e "Qual é o grupo de alimentos em que a expressão 'Pode conter' é predominante?". Métodos: Foram obtidas fotografias de 916 produtos, dos quais 518 foram analisados. Os dados dos rótulos foram avaliados de acordo com os grupos da pirâmide alimentar brasileira (Cereais, Frutas & Vegetais; Soja & Derivados; Leite & Laticínios; Carne & Ovos; Gorduras & Óleos; Açúcares & Doces). Dez itens foram analisados nos rótulos: presença de lista de ingredientes; frase de alerta para alérgicos; frase de alerta; local da frase; frase em letras maiúsculas; frase em negrito; a cor da frase de alerta contrastando com o fundo; tamanho de fonte adequado; não alegar ausência de qualquer alérgeno; outros fatores de difícil leitura. Para a segunda questão, foi respondido questionário estruturado, e os produtos classificados em categorias: "Contém" e "Pode conter". Resultados: A qualidade do rótulo foi adequada e 69% dos alimentos embalados continham pelo menos um alérgeno. A informação "Pode conter" foi mais identificada em: proteína do leite (Cereais e Carnes e ovos), soja (Soja & derivados) e proteína do ovo (Cereais). Soja e derivados foi o grupo alimentar de maior insegurança. Conclusões: Profissionais de saúde podem contar com rotulagem de boa qualidade dos produtos embalados e, consequentemente, promover a educação de pais/cuidadores para consultar os rótulos e gerenciar os riscos em alimentos processados. Soja e produtos são os alimentos com maior insegurança entre os Grupos da Pirâmide Brasileira.

A protocol for an interventional study on the impact of transcutaneous parasacral nerve stimulation in children with functional constipation.

INTRODUCTION: Transcutaneous parasacral nerve stimulation (TPNS) via electrodes placed over the sacrum can activate afferent neuronal networks noninvasively, leading to sacral reflexes that may improve colonic motility. Thus, TPNS can be considered a promising, noninvasive, and safe method for the treatment of constipation. However, there is no published study investigating its use in children with functional constipation. This is a single-center, prospective, longitudinal, and interventional study designed to assess the applicability and clinical outcomes of TPNS in functionally constipated children. PATIENT CONCERNS: Parents or guardians of patients will be informed of the purpose of the study and will sign an informed consent form. The participants may leave the study at any time without any restrictions. DIAGNOSIS: Twenty-eight children (7-18 years old) who were diagnosed with intestinal constipation (Rome IV criteria) will be included. INTERVENTIONS: The patients will be submitted to daily sessions of TPNS for a period of 4 or 8 weeks and will be invited to participate in semistructured interviews at 3 or 4 moments: 1 week before the beginning of TPNS; immediately after the 4 and/or 8 weeks of TPNS; and 4 weeks after the end of the intervention period. In these appointments, the aspects related to bowel habits and quality of life will be assessed. OUTCOMES: This study will evaluate the increase in the number of bowel movements and stool consistency, the decrease in the number of episodes of retentive fecal incontinence, and the indirect improvement in the overall quality of life. CONCLUSION: we expect that this study protocol can show the efficacy of this promising method to assist the treatment of children with functional constipation.

Transcutaneous posterior tibial nerve stimulation in children and adolescents with functional constipation: A protocol for an interventional study.

INTRODUCTION: A vast majority of children with functional constipation respond to the standard medical treatment. However, a subset of patients may present with an unsatisfactory response and only minor improvement of symptoms. Transcutaneous posterior tibial nerve stimulation (PTNS) involves electrical stimulation of the posterior tibial nerve at the level of the ankle, transcutaneously through electrodes fixated on the overlying skin. Stimulation of the tibial nerve can modulate urinary and defecatory function through the stimulation of sacral nerves. Thus, transcutaneous PTNS can be considered a very promising, noninvasive, and safe method to be used in the pediatric age group. However, there is still no published study that has investigated its use in children for the treatment of intestinal constipation. This is a single-center, prospective, longitudinal, and interventional study designed to assess the applicability and clinical outcomes of transcutaneous PTNS in children with functional intestinal constipation. Children will be submitted to daily sessions of transcutaneous PTNS for a period of 4 weeks. All children will also be invited to participate in semistructured interviews, 1 in each of the 3 assessments: 1 week before the start of the intervention; immediately after the 4 weeks of intervention; and 4 weeks after the end of the intervention period. In these interviews, the aspects related to bowel habits and quality of life will be assessed. This project aims to evaluate the clinical outcomes of transcutaneous PTNS in children with functional intestinal constipation and the applicability of this kind of treatment. CONCLUSIONS: This protocol intended to demonstrate the efficacy of this promising method to increase the number of bowel movements and the stool consistency, to reduce the number of episodes of retentive fecal incontinence, and to indirectly improve the overall quality of life.

Intake, bioavailability, and absorption of iron in infants aged 6 to 36 months: an observational study in a Brazilian Well Child Clinic

BACKGROUND: Preventing the development of iron deficiency anemia during infancy requires the appropriate complementary foods with high energy, nutrient density, and adequate iron content, as well as high nutrient bioavailability. We aimed to evaluate iron intake, bioavailability, and absorption from foods, in healthy infants and toddlers at a Well Child Clinic. METHODS: This observational, cross-sectional, descriptive study evaluated 96 consecutive infants and toddlers, 6 to 12 months of age (group I) and 13 to 36 months of age (group II) that were brought for regular pediatric visits and introduced to complementary foods. Quantitative 24-h dietary recalls were obtained, and iron intakes quantified for lunch and dinner. Iron bioavailability and absorption were calculated and analyzed by Monsen's and FAO/WHO's methods according to enhancing factors: meat, poultry, and fish (MPF) and vitamin C. RESULTS: There were no significant differences in demographic, clinical, and anthropometric variables between groups. Vitamin C intake was not different between groups, but MPF was significantly lower in group I. The proportion of children with recommended RDA iron intake was lower (p< 0.05) in group I (16 %) than that in group II (47 %). Group I had lesser MPF intake and iron absorption and a higher proportion of children with low bioavailability in lunch and dinner when compared to group II (p< 0.05).CONCLUSIONS: Inclusion of low-cost meat, especially chicken meat and vitamin C-rich foods, at the same meal, both in lunch and dinner, would be of particular advantage to ensure an adequate intake of bioavailable iron during complementary feeding.

Prevalence of broncopulmonary and otorhinolaryngologic symptoms in children under investigation for gastroesophageal reflux disease: retrospective analysis.

UNLABELLED: Gastroesophageal reflux disease (GERD) is a common ailment in children, adding up to the evidence that gastroesophageal reflux is an important cofactor in upper airway disorders, especially in the pediatric population. It is very common for it to impact the upper and lower airways. Our goal was to assess the presence of otorhinolaryngological symptoms in children aged between one and twelve years in whom gastroesophageal reflux is suspected. MATERIALS AND METHODS: We assessed data from the charts of patients up to 12 years of age submitted to 24 hour pH measuring of one of two channels, placed at 2 and 5 cm from the LEE in order to confirm the diagnosis of Gastroesophageal Reflux Disease. RESULTS: We studied 143 charts from children who underwent 24 hour pH measuring to investigate GERD; however, only 65 were included. The most prevalent symptoms in the children were bronchopulmonary, found in 89.2%, of sinonasal symptoms (72.3%), otologic (46.1%) and repetition UAW infections (44.6%). When we compared the presence of each group of symptoms of the results from the pH measuring, no significant differences were found between the symptoms and the pH measuring results. CONCLUSION: GERD can manifest in different ways and otorhinolaryngological symptoms are frequent in children.

A Doença do Refluxo Gastroesofágico (DRGE) é uma afecção comum na infância, aumentando as evidências de que o refluxo gastroesofágico seja um cofator importante que contribui para as desordens de vias aéreas, principalmente na população pediátrica. É muito comum serem observadas manifestações em vias aéreas superiores e inferiores. Nosso objetivo é avaliar a presença de sintomas otorrinolaringológicos em crianças com idade de um a 12 anos e suspeita de doença do refluxo gastroesofágico. MATERIAIS E MÉTODO: Foram avaliados dados de prontuários de pacientes de até 12 anos submetidos à pHmetria de 24 horas de um ou dois canais, locados a 2 e 5 cm do EEI para confirmação de diagnóstico de Doença do Refluxo Gastroesofágico. RESULTADOS: Foram analisados 143 prontuários de crianças que realizaram pHmetria de 24 horas para investigação de DRGE; porém 65 foram incluídas. Os sintomas mais prevalentes nas crianças eram os broncopulmonares, encontrados em 89,2 por cento, de sintomas nasossinusais (72,3 por cento) , otológicos (46,1 por cento) e de infecções de VAS de repetição (44,6 por cento). Quando comparada a presença de cada grupo de sintomas com o resultado da pHmetria, não foi encontrada diferença significativa entre os sintomas e o resultado da pHmetria. CONCLUSÃO: DRGE pode se manifestar de diversas maneiras e os sintomas otorrinolaringológicos são frequentes em crianças.

Achados histopatológicos gástricos em crianças e adolescentes brasileiros com dispepsia e infecção por Helicobacter pylori / Gastric histopathological findings in Brazilian dyspeptic children and adolescents with helicobacter pylori infection

Avaliar as características histopatológicas da mucosa gástrica, duodenal e esofágica de crianças e adolescentes brasileiros infectados por Helicobacter pylori (H. pylori) e submetidas à endoscopia digestiva alta para investigar dispepsia crônica. As correlações entre variáveis clínicas e histopatológicas também foram analisadas. Foi realizado estudo prospectivo de biópsias do trato gastrointestinal superior (mucosa gástrica, duodenal e esofágica) em crianças e adolescentes de 4 a 17 anos de idade. A análise histopatológica foi realizada com coloração por Hematoxilina & Eosina, as lesões gástricas e duodenais foram classificadas de acordo com o Sistema Sydney atualizado e a intensidade da esofagite foi graduada. O estudo incluiu um grupo de crianças infectadas por H. pylori (Hp+), com resultados positivos para dois testes (teste da urease e histologia) e um grupo de não infectadas (Hp-). Utilizou-se teste de Mann-Whitney, Qui-Quadrado, exato de Fisher e correlação de Spearman, sendo p<0,05 considerado significativo. Foram estudadas 185 crianças dispépticas (idade 9.5±2.7 anos), 63,2% (117/185) do sexo feminino, 96 (51,8%) H. pylori positivos (Hp+) e 89 (48,2%) H. pylori negativos (Hp-). O grupo Hp+ foi significativamente mais velho (9.9±2.8 anos) do que o grupo Hp- (9.0±2.6 anos) (p=0,02). Não houve diferença entre a proporção de sintomas entre os grupos Hp+ e Hp-. Não foram encontradas úlcera gástrica ou duodenal durante o procedimento endoscópico. Gastrite crônica ativa moderada/grave esteve presente em 70,5% das biópsias do antro e em 45,2% das biópsias do corpo no grupo Hp+, com intensidade significativamente maior no antro do que no corpo (p<0,05)...

To evaluate the histopathological features of the gastric, duodenal and esophageal mucosa from Brazilian children and adolescents infected with Helicobacter pylori (H. pylori), submitted to upper gastrointestinal endoscopy to investigate chronic dyspepsia. The correlations between clinical and histopathological variables were also analyzed. A prospective study of biopsies from the upper gastrointestinal tract (gastric, duodenal and esophageal mucosa) was performed on children and adolescents 4 to 17 years-old. The histopathological analysis was performed on Hematoxylin-and-Eosin-stained slides, the gastric and duodenal lesions were graded according to the updated Sydney System and the intensity of esophagitis was recorded. The study included one group of H. pylori infected children (Hp+), with positive results for two tests (rapid urease test and histology) and one uninfected group (Hp-). Mann-Whitney, Chi-square, Fisher exact test and Spearman rank correlation were performed and p<0.05 considered significant. We studied 185 dyspeptic children (age 9.5±2.7 years), 63.2% (117/185) female, 96 (51.8 %) H. pylori positive (Hp+) and 89 (48.2%) H. pylori negative (Hp-). H. pylori-positive were significantly older (9.9±2.8 years) than Hp- (9.0±2.6 years) (p=0.02). There was no difference among the proportion of symptoms between Hp+ and Hp- groups. Gastric or duodenal ulcers were not found during the endoscopic procedure. Moderate/severe chronic active gastritis was present in 70,5% of antrum biopsies and in 45,2% of corpus biopsies in the Hp+ group, with significantly higher grading in antrum than in corpus (p<0.05)...

Prevalência de sobrepeso/obesidade em crianças e adolescentes com constipação crônica funcional / Overweight/obesity prevalence in children and adolescents with chronic functional constipation

OBJETIVO: Avaliar a prevalência do sobrepeso/obesidade em um grupo de crianças com constipação crônica funcional. MÉTODOS: Estudo retrospectivo com 257 crianças de dois a 15 anos com constipação crônica funcional diagnosticada segundo critérios de Roma II, atendidas consecutivamente em clínica terciária de gastroenterologia pediátrica. Informações demográficas, clínicas, diagnósticas e antropométricas foram obtidas de prontuários. O índice de massa corporal (IMC) foi calculado e utilizou-se a referência do Centers for Disease Control para determinar o percentil de IMC para idade e gênero. Crianças com percentil de IMC>85 foram consideradas com sobrepeso/obesidade; as com percentis > 5 e <85 foram classificadas como eutróficas. RESULTADOS: Para as variáveis sociodemográficas e clínicas, não houve diferença estatisticamente significante entre os subgrupos sobrepeso/obesidade e eutrofia. A prevalência de crianças constipadas com sobrepeso/obesidade foi de 24,%. A média dos percentis do subgrupo sobrepeso/obesidade foi 94,4±4,3; a das eutróficas foi 45,3±24,2. A prevalência de sobrepeso/obesidade foi similar em ambos os sexos e grupos etários (<7 anos e >7 anos). CONCLUSÕES: Os subgrupos dos eutróficos e sobrepeso/obesidade foram homogêneos nas características sociodemográficas e clínicas, sugerindo que tais variáveis não influenciaram na prevalência do excesso de peso. A prevalência estimada de sobrepeso/obesidade entre as crianças com constipação crônica funcional está dentro dos valores esperados para a população pediátrica brasileira.

OBJECTIVE: To determine the prevalence of overweight/obesity in a group of children with chronic functional constipation. METHODS: Retrospective chart review of 257 children with chronic functional constipation as defined by Rome II criteria, 2-15 years old, assisted in a tertiary pediatric gastroenterology clinic. Demographic, clinical, diagnostic and anthropometric information was extracted from the charts. Body mass index (BMI) was calculated and The Centers for Disease Control's BMI growth reference was used to determine age and gender-specific BMI percentiles of the children. Overweight/obesity was classified as a BMI of >85th percentile, and euthrophy as BMI >5th and <85th percentile. RESULTS: There was no statistically significant difference for demographics and clinical variables between the subgroups overweight/obesity and eutrophy. In constipated children, prevalence of overweight/obesity was 24.4%. Prevalence of overweight/obesity did not differ between boys and girls or across age groups (<7 years and >7 years). CONCLUSIONS: Demographics and clinical characteristics were similar between the overweight/obese and eutrophic subgroups, which suggests that these characteristics do not influence on the prevalence of overweight/obesity in constipated children. The estimated prevalence of overweight/obesity in this group was similar to the prevalence of age-matched reference for Brazilian children.

Constipação crônica na infância: quanto estamos consultando em gastroenterologia pediátrica? / Chronic constipation in childhood: how many visits to the pediatric gastroenterologist?

OBJETIVO: Comparar dois períodos em relação ao atendimento de constipação crônica - Tempo A (1992 a 1995) e Tempo B (2002 a 2005), avaliando o número de consultas por problemas gastrintestinais; o número e a porcentagem de consultas de crianças com constipação crônica; e o número de atendimentos de crianças com constipação crônica por período de atendimento. MÉTODOS: No Tempo A, 359 pacientes foram atendidos em um período de quatro horas por semana. No Tempo B, 624 pacientes foram atendidos em três períodos de quatro horas, totalizando 12 horas por semana. RESULTADOS: Houve aumento no número absoluto de pacientes, no número de consultas por problemas gastrintestinais (2,8 vezes) e no número de consultas por constipação crônica (2,6 vezes) no Tempo B, em relação ao Tempo A. Houve manutenção na proporção de consultas por constipação crônica: média de 35,6 por cento no Tempo A e 34,6 por cento no Tempo B. Ocorreu aumento no número de períodos de atendimento no Tempo B (2,9 vezes maior), com igual número de consultas por período de atendimento (média de 17,4 no Tempo A e 16,6 no Tempo B) e de consultas por constipação crônica por período de atendimento (média de 6,1 no Tempo A e 5,5 no Tempo B). CONCLUSÕES: O aumento no número absoluto, e não na proporção de atendimentos por constipação crônica, pode ter ocorrido pela manutenção da prevalência populacional deste distúrbio, gerando demanda contida de encaminhamento pelo pediatra generalista. O despreparo do pediatra generalista para o atendimento deste problema poderia levar a um aumento no número de encaminhamentos aos pediatras especialistas.

OBJECTIVE: To compare two periods (A - 1992-1995 and B - 2002-2005) regarding the number of office visits for chronic constipation, considering the number of visits for gastrointestinal problems; the number and percentage of visits for chronic constipation; and the number of visits for constipation per period of care. METHODS: During period A, 359 patients were assisted for a period of four hours/week. During period B, 624 patients were assisted at three different periods of four hours/week. RESULTS: From A to B, there was an increase in: number of patients assisted, number of visits due to gastrointestinal problems (2.8 times) and number of visits due to constipation (2.6 times). However, the proportion of visits due to constipation was similar in both periods (A - 35.6 percent and B - 34.6 percent). Also, there was a rise in the number of periods for clinical assistance in Time B (2.9 times greater), with an equal mean number of visits per period (A - 17.4 and B - 16.6) and mean visits due to constipation per period (A- 6.1 and B - 5.5). CONCLUSIONS: The increase number, but not proportion, of visits for constipation may have occurred due to a stable population prevalence of this disorder, generating demand beyond the capacity for referral by generalist pediatricians. Also, the lack of skill of the generalist pediatrician to manage this clinical problem could have increased the number of referrals to specialists.
