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.

Association between Clinical and Histopathological Findings in Intestinal Neuronal Dysplasia Type B: An Advance towards Its Definition as a Disease.

INTRODUCTION: Intestinal neuronal dysplasia type B (IND-B) is a controversial entity that affects the submucosal nerve plexus of the distal intestine. The lack of definition of the causal relationship between histological findings and clinical symptoms has been identified as the primary point to be elucidated in the scientific investigation related to IND-B, which is essential for it to be considered a disease. OBJECTIVE: To investigate the relationship between histopathological findings and symptoms in a series of patients with IND-B. METHODS: Twenty-seven patients with histopathological diagnosis of IND-B, according to the Frankfurt Consensus (1990), who underwent surgical treatment through colorectal resections were included. Data from medical records regarding the clinical picture of the patients at the time of diagnosis, including the intestinal symptom index (ISI) and a detailed histopathological analysis of the rectal specimens, were retrieved. Exploratory factor analysis was performed, applying the principal components method for clusters with Varimax rotation. RESULTS: Two factors were determined: the first, determined by histopathological and clinical variables, and the second, composed of the main symptoms presented in patients with IND-B, including ISI. Factorial rotation showed the association between the two factors and, through a graph, demonstrated the proximity between ISI values and histopathological alterations. CONCLUSION: There was evidence of an association between the clinical features presented by patients with IND-B and the histopathological findings of the rectal samples. These results support the understanding of IND-B as a disease.

Transcutaneous Neuromodulation for Constipation and Fecal Incontinence in Children: A Systematic Review and Meta-Analysis.

INTRODUCTION: Constipation is a disorder with a multifactorial origin. Constipation has a varied clinical presentation, including infrequent defecation of bulky stools and episodes of retentive fecal incontinence. Neuromodulation has been used to treat many health problems, with promising results. OBJECTIVE: To conduct a systematic review of randomized clinical trials based on the effects of transcutaneous neuromodulation in treating constipation and retentive fecal incontinence in children and adolescents. METHODS: A systematic review of randomized clinical trials was performed. Medline (PubMed), PEDro, SciELO, Cochrane (CENTRAL), Embase, and Scopus databases were searched from March 2000 to August 2022. We included clinical trials evaluating transcutaneous neuromodulation in children with constipation and fecal incontinence compared or associated with other types of treatment. Two reviewers independently selected relevant studies, assessed the methodological quality, and extracted the data. RESULTS: Three studies with 164 participants were included in this review. Two meta-analyses were generated based on these studies. These analyses revealed that transcutaneous neuromodulation is an effective adjuvant treatment modality that improves children's constipation and retentive fecal incontinence. The methodological quality of the included studies was classified as high based on the assessment of the quality of evidence, with a high degree of confidence based on the GRADE system. CONCLUSIONS: Transcutaneous neuromodulation is an effective adjuvant treatment modality for children with constipation and retentive fecal incontinence.

Agreement between histopathological and intraoperative classifications for pediatric appendicitis and its relationship with the post-operative clinical outcome.

Introduction: Some studies have shown poor agreement between intraoperative and histopathological classifications for appendicitis, despite their routine use in clinical practice. Objective: To investigate the agreement between histopathological and intraoperative classifications for pediatric appendicitis and evaluate the predictive potential of these classifications for the post-operative outcome. Methods: A retrospective, longitudinal, observational single-center study, carried out with 485 patients up to15 years of age, with a confirmed diagnosis of acute appendicitis by histopathological evaluation. The histopathological results classified the appendices as uncomplicated appendicitis when there was confirmation of the diagnosis of appendicitis without necrosis or perforation and complicated appendicitis when there was extensive necrotic tissue in the outer layer of the appendix or signs of perforation. The intraoperative findings were classified as uncomplicated appendicitis when the appendix presented with hyperemia and edema or fibrinous exudate and complicated appendicitis when the appendix showed necrosis, abscess, or perforation. The kappa index determined the agreement and the prediction relationships using a generalized linear model. Results: 43.9% of cases were classified as complicated appendicitis by histopathological evaluation and 49.7% by intraoperative classification. The agreement analysis between the histopathological and intraoperative classification showed a moderate agreement, with a Kappa index of 0.419 (0.337-0.501). There was an association (P < 0.05) between the intraoperative classification and the post-operative clinical outcomes (time to start feeding, fever, intraabdominal collection, length of stay, the need for antibiotic therapy changing, and need for ICU). There was no association between histopathological classification and post-operative outcomes. Conclusion: The agreement between the two classifications was moderate, and the intraoperative classification was able to predict the post-operative clinical outcomes.

Brazilian Portuguese version of the Amsterdam infant stool scale: a valid and reliable scale for evaluation of stool from children up to 120 days old.

BACKGROUND: For newborns and infants wearing diapers the difficulties in characterizing the appearance of the stool are significant, since the changes in consistency, quantity, and color of the stool are higher than in other age groups. The Amsterdam Infant Stool Scale (AISS) was created and validated in 2009, providing a specific tool for the evaluation of the stool of children up to 120 days old. However, to be used in clinical practice and scientific investigations in Brazil, it is mandatory to perform the translation and cross-cultural adaptation process for Brazilian Portuguese language. Thus, we aim to perform the translation and cross-cultural adaptation of AISS into Brazilian Portuguese and to evaluate the psychometric properties of the translated version. METHODS: The process of translation and cross-cultural adaptation was performed according to the internationally accepted methodology, including: translation, summary of translations, backtranslation, preparation of the pre-final version, application of the pre-test and determination of the final version. The evaluation of the psychometric properties was performed through the application of Brazilian Portuguese AISS, by five examiners (including child health field specialists and a literate adult lay on the subject), analyzing 238 stool photographs of children under 120 days old. The intra and inter-examiner agreement values were determined using kappa statistic. The validity of the criterion was investigated through correlation analysis (Kendall's coefficient) between the classifications determined by the non-specialist examiner and the expert examiners. RESULTS: In all 30 tests performed between different examiners, there was an agreement considered as at least moderate (kappa values above 0.40). The intra-examiner reliability was considered as substantial (kappa> 0.6). There was a statistically significant correlation (p <  0.05) between the classifications determined by the examiners considered as specialists and the examiner considered as non-specialist. CONCLUSION: The Brazilian Portuguese AISS version proved to be valid and reliable to be used by healthcare professionals and the general public in the evaluation of stool from children up to 120 days old.

Rectal Biopsy Technique for the Diagnosis of Hirschsprung Disease in Children: A Systematic Review and Meta-Analysis.

ABSTRACT: The diagnosis of Hirschsprung disease (HD) depends on the histopathological analysis of rectal biopsies. This review aims to define the best rectal biopsy technique. A systematic literature review and proportional meta-analysis of the available case series studies of rectal biopsies were performed in this study. All case series with more than five rectal biopsies in children younger than 18 years of age suspected of HD that described at least one type of rectal biopsy were included. The studies that did not specify the rate of conclusive results and the rate of complications of the biopsy procedures were excluded. According to the literature review, there were four different techniques of rectal biopsy: open, suction, punch, and endoscopic. In the title and abstract screening process, we assessed 496 articles, 159 fulfilled the eligibility criteria, and 71 studies reported our outcomes of interest and were included in the meta-analysis. The pooled proportion of conclusive results was 94% in open biopsies (95% CI 0.89-0.98), 95% in punch (95% CI 0.90-0.98), and 88% in suction group (95% CI 0.85-0.92). The pooled proportion of complication rates was 2% in open biopsies (95% CI 0.00031-0.04), 0.039% in suction (95% CI 0.00023-0.0006), and 2% in punch biopsies (95% CI 0.00075-0.04). Suction, punch, and open techniques presented comparable rates of conclusive results. In the suction group, the association between different methods of histopathological analysis increased conclusive results rates; however, the punch biopsy was associated with significantly higher complication rates than the suction technique.

Are biopsies always necessary in upper and lower gastrointestinal endoscopy in children? A retrospective 10-year analysis.

Little attention has been given to the efficiency and validity of performing routine endoscopic biopsies in normal areas in children. This study aimed to investigate the need to perform routine biopsies in upper gastrointestinal endoscopy (UDE) and colonoscopy in normal areas by comparing macroscopy and histology. It was a 10-year retrospective analysis with the inclusion of 761 UDEs and 177 colonoscopies. Considering all segments, UDEs showed false-positive result rates of 73.11% and false-negative result rates of 14.34%. The histological results modified the initial management in 53.95% of patients. Considering all segments, colonoscopies showed false-positive result rates of 63.64% and false-negative result rates of 30.97%. The histological results modified the initial management in 34.45% of patients.Conclusion: If biopsies were obtained only in abnormal areas, the diagnosis would be lost in 53.95% of the patients in upper endoscopies and 85.7% of the colonoscopies, which justifies routine maintenance of biopsies in macroscopically normal areas in children. What is Known: • Little attention has been given to the efficiency and validity of endoscopic biopsies of normal areas during pediatric exams. • Only a few pediatric studies have correlated macroscopic and histological findings from endoscopic biopsies, and low sensitivity and specificity, as well as poor agreement, were reported. What is New: • Our study confirms the evidence that routine biopsies from macroscopically normal areas during upper and lower digestive endoscopies can lead to histopathological diagnoses and different medical management. • This is the first research on this topic in a Latin population, from a developing country, reassuring the results obtained in previous papers from other countries.

What should be the treatment for intestinal neuronal dysplasia type B? A comparative long-term follow-up study.

PURPOSE: To present the long-term follow-up outcomes of patients with intestinal neuronal dysplasia type B (IND-B) managed either conservatively or surgically. METHODS: We conducted an ambispective, observational, longitudinal, and comparative study. Clinical data were reviewed at the start of treatment. After a minimum period of five years, the patients participated in semi-structured interviews in which the bowel function score (BFS) was applied to assess intestinal function, a proposed intestinal symptom index (ISI) to assess clinical symptoms, and a classification of clinical prognosis to assess treatment success. Comparisons between the two types of treatment were performed by evaluating pre- and post-treatment criteria. RESULTS: Fifty patients diagnosed with IND-B were included in the study. Thirty-eight patients underwent surgical treatment (26 elective surgical treatment for primary colorectal resection and 12 emergency colostomies for intestinal obstruction or enterocolitis). Twelve patients were managed conservatively. With the exception of the patients who required an emergency operation (n = 12), the two groups were composed of patients with severe constipation who had similar clinical and functional characteristics at the time of IND-B diagnosis. A better clinical response was observed in patients submitted to conservative treatment, with a greater increase in the BFS (16.5 [-4/+18] versus 4 [-15/+17]; p = 0.001), indicating better bowel function and a more pronounced drop in ISI (-6 [-7/-4] versus -4 [-6/+1]; p = 0.015), suggesting fewer symptoms. The percentage of patients who had a successful treatment was higher in the group treated conservatively (72.7% versus 42.3%; p = 0.03). CONCLUSION: Conservative management showed better long-term outcomes than surgical management in children with IND-B.

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.

Ultrastructural analysis of bone formation around dental implants in nondiabetic rats, severe diabetics not controlled and controlled with insulin.

PURPOSE: To evaluate bone formation through ultrastructural analysis around titanium implants in severe alloxanic uncontrolled diabetic rats, and controlled with insulin, in comparison with nondiabetic rats. METHODS: Thirty-six male Wistar rats, weighing between 200 and 300 g, divided into three experimental groups: normal control group (G1), a diabetic group without treatment (G2), and a diabetic group treated with insulin (G3). The animals received titanium implants in the right femur, and osseointegration was evaluated at 7, 14, and 21 days after surgery, through ultrastructural analysis using scanning electron microscopy. RESULTS: The ultrastructural analysis showed a dense bone structure in the G1, few empty spaces and a small number of proteoglycans; G2 presented bone matrix with a loose aspect, irregular arrangement, thin trabeculae, empty spaces and a large number of proteoglycans; G3 obtained similar results to G1, however with a higher number of proteoglycans. CONCLUSION: Severe diabetes caused ultrastructural changes in bone formation, and insulin therapy allowed an improvement in osseointegration, but it was not possible to reach the results obtained in the control group.

MicroRNA expression profiles in the esophagus of children with caustic stenosis: A pathway towards esophageal cancer?

BACKGROUND: Eighty percent of caustic ingestions occur in children and esophageal neoplasms may develop as a late complication of such injury. The identification of biomarkers is a promising strategy to improve early diagnosis of esophageal cancer or caustic lesions that are at an increased risk of progression. STUDY DESIGN/AIMS: This study aimed at identifying global microRNA (miRNA) expression changes in esophageal mucosa from children with caustic stenosis. The study included 27 biopsy samples from 15 patients. Samples were divided into two groups, according to the time elapsed after injury (N = 15 in Group A, with less than five years of follow-up and N = 12 in Group B, with more than five years of follow-up). miRNA expression profiles were determined in each lesion, compared with normal esophageal tissues from control group. We used the TaqMan Human MicroRNA Arrays (Thermo Fisher) platform. Furthermore, bioinformatic algorithms were used to identify miRNA target genes and biological pathways including miRNAs and their target genes potentially associated with esophageal disease. RESULTS: Thirteen miRNAs were significantly deregulated (9 over- and 4 underexpressed) in patients from Group A. In patients from Group B, two miRNAs were over- and two were underexpressed. Of note, miR-374 and miR-574 were deregulated in Group B patients and have been linked to esophageal tumorigenesis. We identified signal transduction and transcription factor networks with genes strongly related to development and progression of esophageal cancer. CONCLUSION: miRNAs identified here contribute to a better understanding of pathways associated with malignant transformation from caustic stenosis to neoplastic lesions. This study may serve as a basis for validation of miRNAs, including miR-374 and miR-574, as potential biomarkers of early cancer detection.

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.

Implementation of a surgical screening system for urgent and emergent cases in a tertiary hospital. / Implementação de um modelo de triagem cirúrgica para casos urgentes em um hospital terciário.

OBJECTIVE: to evaluate the applicability of the "Timing of Acute Care Surgery" (TACS) color classification system in a tertiary public hospital of a developing country. METHODS: we conducted a longitudinal, retrospective study in a single center, from March to August 2016 and the same period in 2017. We opted for the selection of four surgical specialties with high demand for emergencies, previously trained on the TACS system. For comparisons with the previous classifications, we considered emergencies as reds and oranges and urgencies, as yellow, with an ideal time interval for surgery of one hour and six hours, respectively. RESULTS: non-elective procedures accounted for 61% of the total number of surgeries. The red, orange and yellow classifications were predominant. There was a significant improvement in the time before surgery in the yellow color after the TACS system. Day and night periods influenced the results, with better ones during the night. CONCLUSION: this is the first study to use the TACS system in the daily routine of an operating room. The TACS system improved the time of attendance of surgeries classified as yellow.

OBJETIVO: avaliar a aplicabilidade do sistema de classificação de cores "Timing of Acute Care Surgery" (TACS) em um hospital público terciário de um país em desenvolvimento. MÉTODOS: estudo longitudinal, retrospectivo, de um único centro, de março a agosto de 2016 e o mesmo período em 2017. Optou-se pela seleção de quatro especialidades cirúrgicas com alta demanda de urgências, as quais foram previamente treinadas sobre o sistema TACS. Para comparação com as classificações prévias de urgência e emergência, emergências foram consideradas como vermelhas e laranjas e urgências como amarelas, com intervalo de tempo ideal para cirurgia de uma hora e de seis horas, respectivamente. RESULTADOS: os procedimentos não eletivos representaram 61% do número total de cirurgias. As classificações vermelha, laranja e amarela foram predominantes. Houve melhora significativa do tempo para a cirurgia na cor amarela após o sistema TACS. Períodos diurnos e noturnos influenciaram os resultados, com melhores resultados durante o período noturno. CONCLUSÃO: este é o primeiro estudo que usou o sistema TACS no dia a dia de um centro cirúrgico, e demonstrou que o sistema TACS melhorou o tempo de atendimento das cirurgias classificadas como amarelas.

Brazilian Portuguese translation, cross-cultural adaptation and reproducibility assessment of the modified Bristol Stool Form Scale for children / Tradução para o português (Brasil), adaptação transcultural e avaliação da reprodutibilidade da Escala de Bristol para Consistência de Fezes modificada para crianças

Abstract Objective: To translate and culturally adapt the modified Bristol Stool Form Scale for children into Brazilian Portuguese, and to evaluate the reproducibility of the translated version. Methods: The stage of translation and cross-cultural adaptation was performed according to an internationally accepted methodology, including the translation, back-translation, and pretest application of the translated version to a sample of 74 children to evaluate the degree of understanding. The reproducibility of the translated scale was assessed by applying the final version of Brazilian Portuguese modified Bristol Stool Form Scale for children to a sample of 64 children and 25 healthcare professionals, who were asked to correlate a randomly selected description from the translated scale with the corresponding representative illustration of the stool type. Results: The final version of Brazilian Portuguese modified Bristol Stool Form Scale for children were evidently reproducible, since almost complete agreement (k > 0,8) was obtained among the translated descriptions and illustrations of the stool types, both among the children and the group of specialists. The Brazilian Portuguese modified Bristol Stool Form Scale for children was shown to be reliable in providing very similar results for the same respondents at different times and for different examiners. Conclusion: The Brazilian Portuguese modified Bristol Stool Form Scale for children is reproducible; it can be applied in clinical practice and in scientific research in Brazil.

Conclusão: A Escala de Bristol para Consistência de Fezes modificada para crianças em português (Brasil) é reproduzível e pode ser aplicada na prática clínica e em pesquisa científica no Brasil.

Accidents in childhood: casuistry of a tertiary service in a medium-sized city in Brazil. / Acidentes na infância: casuística de um serviço terciário em uma cidade de médio porte do Brasil.

OBJECTIVE: to investigate the main causes and most common risk situations related to childhood accidents, in our local reality. METHODS: an observational, cross-sectional, retrospective, descriptive, and analytical study from the medical records of patients attended in the pediatric emergency services of the hospital complex of Hospital das Clínicas, Botucatu Medical School - UNESP, in 2016. We included patients from zero to 15 years old who had received medical care related to accidents, determining age, gender, type of accident, period of the day, accident place, and history of previous accidents. RESULTS: considering all consultations with appropriate medical records, 936 (27.5%) were related to accidents: 588 (62.8%) in male patients and 348 (37.2%) in female patients. As to age, 490 (52.3%) happened with children from zero to five years, 245 (26.2%) with children from six to ten years, and 201 (21.5%) with children over ten years. Falls and local traumas were the most common types of accidents in all analyzed age groups. Most accidents occurred in the afternoon (46.1%), at home (60.7%), and 26.6% of the patients had a history of previous accidents. CONCLUSION: accidents were responsible for a large portion of urgent care. The high rate of patients with previous accident records indicated the repeated exposure of these children to risk situations.

OBJETIVO: investigar as principais causas e situações de risco mais comuns relacionadas aos acidentes na infância, em nossa realidade local. MÉTODOS: estudo observacional, transversal, retrospectivo, descritivo e analítico, a partir dos prontuários médicos de pacientes atendidos nos serviços de urgências pediátricas do complexo hospitalar do Hospital das Clínicas da Faculdade de Medicina de Botucatu - UNESP, no ano de 2016. Foram incluídos os atendimentos de pacientes de zero a 15 anos de idade que haviam recebido atendimento médico relacionado a acidentes, determinando-se idade, sexo, tipo de acidente, período do dia e ambiente onde aconteceu o acidente e histórico de acidentes pregressos. RESULTADOS: do total de atendimentos com registros adequados no prontuário, 936 (27,5%) estavam relacionados a acidentes: 588 (62,8%) em pacientes do sexo masculino e 348 (37,2%) em pacientes do sexo feminino. Quanto à idade, 490 (52,3%) acidentes ocorreram com crianças de zero a cinco anos, 245 (26,2%) com crianças de seis a dez anos e 201 (21,5%) com crianças com mais de dez anos de idade. Quedas e traumas locais foram os tipos de acidentes mais comuns em todas as faixas etárias analisadas. A maior parte dos acidentes ocorreu à tarde (46,1%), em casa (60,7%), e 26,6% dos pacientes apresentavam antecedentes de acidentes prévios. CONCLUSÃO: os acidentes foram responsáveis por grande parcela dos atendimentos de urgência. A elevada taxa de pacientes com registros de acidentes prévios indica a exposição repetida destas crianças às situações de risco.

Combinations of laxatives and green banana biomass on the treatment of functional constipation in children and adolescents: a randomized study / Combinações de laxantes e biomassa de banana verde no tratamento de constipação funcional em crianças e adolescentes: estudo randomizado

Abstract Objectives: Evaluate the effect of combinations of green banana biomass and laxatives in children and adolescents with chronic constipation. Methods: This was a randomized study of 80 children and adolescents with functional constipation according to the Rome IV Criteria, who were divided into five groups: (1) green banana biomass alone; (2) green banana biomass plus PEG 3350 with electrolytes; (3) green banana biomass plus sodium picosulfate; (4) PEG 3350 with electrolytes alone; and (5) sodium picosulfate alone. Primary outcome measure was the reduction of the proportion of patients with Bristol Stool Form Scale ratings 1 or 2. Secondary outcome measures were: increase of the proportion of >3 bowel movements/week and reduction of the proportion of fecal incontinence, straining on defecation, painful defecation, blood in stool, abdominal pain, and decreased laxative doses. Results: On consumption of green banana biomass alone, a statistically significant reduction was observed in the proportion of children with Bristol Stool Form Scale rating 1 or 2, straining on defecation, painful defecation, and abdominal pain. Conversely, no reduction was observed in fecal incontinence episodes/week, blood in stool, and no increase was observed in the proportion of children with >3 bowel movements/week. The percentage of children who required decreased laxative dose was high when green banana biomass was associated with sodium picosulfate (87%), and PEG 3350 with electrolytes (63%). Green banana biomass alone and associated with laxatives was well tolerated, and no adverse effects were reported. Conclusion: Green banana biomass is advantageous as an adjunct therapy on functional constipation, mainly for reducing doses of laxatives.

Resumo Objetivos: Avaliar o efeito das combinações da biomassa de banana verde e laxantes em crianças e adolescentes com constipação crônica. Métodos: Estudo randomizado de 80 crianças e adolescentes com constipação funcional de acordo com os Critérios de Roma IV divididos em cinco grupos: 1) Somente biomassa de banana verde; 2) Biomassa de banana verde mais PEG 3350 com eletrólitos; 3) Biomassa de banana verde mais picossulfato de sódio; 4) PEG 3350 somente com eletrólitos e 5) somente picossulfato de sódio. O desfecho primário foi a redução da proporção de pacientes com as classificações 1 ou 2 da Escala de Bristol para Consistência de Fezes. Os desfechos secundários foram: aumento da produção de > 3 evacuações/semana e redução da proporção de incontinência fecal, esforço na defecação, defecação dolorosa, sangue nas fezes, dor abdominal e redução nas dose de laxantes. Resultados: No consumo somente de biomassa de banana verde há uma redução estatisticamente significativa na proporção de crianças com classificação 1 ou 2 da Escala de Bristol para Consistência de Fezes, esforço na defecação, defecação dolorosa e dor abdominal. Por outro lado, não houve redução nos episódios fecais/semana de incontinência, sangue nas fezes e nenhum aumento na proporção de crianças com > 3 evacuações/semana. O percentual de crianças que tiveram sua dose de laxante reduzida foi alto quando a biomassa de banana verde foi associada a picossulfato de sódio (87%) e PEG 3350 com eletrólitos (63%). A biomassa de banana verde sozinha e associada a laxantes foi bem tolerada e não houve efeitos adversos relatados. Conclusão: A biomassa de banana verde é vantajosa como uma terapia adjuvante na constipação funcional, principalmente na redução das doses de laxantes.

Barium Enema Revisited in the Workup for the Diagnosis of Hirschsprung's Disease.

OBJECTIVE: To analyse the diagnostic capacity of barium enema (BE) in the diagnostic investigation for Hirschsprung's disease (HD) was analyzed for transition zone (TZ) identification and rectosigmoid index (RSI) ≤1.0 determination. PATIENTS AND METHODS: BE images were analyzed retrospectively by 2 examiners and the results were compared with the histopathology of rectal biopsies. RESULTS: TZ identification and RSI ≤1.0 were assessed separately and combined in 43 patients. Twelve (27.9%) patients had the diagnosis of HD based on rectal biopsies. TZ identification presented better diagnostic capacity for the 2 examiners than RSI ≤1.0. However, interexaminer agreement was higher for RSI ≤1.0 than for TZ identification. The combination of TZ identification and RSI ≤1.0 increased the sensitivity (83.3%-92.3%) and the negative predictive value (90.4%-92.3%). CONCLUSION: Therefore, the high diagnostic sensitivity of TZ identification combined to RSI ≤1.0 reinforces the usefulness of these BE parameters in the screening for Hirschsprung's disease.

Brazilian Portuguese translation, cross-cultural adaptation and reproducibility assessment of the modified Bristol Stool Form Scale for children.

OBJECTIVE: To translate and culturally adapt the modified Bristol Stool Form Scale for children into Brazilian Portuguese, and to evaluate the reproducibility of the translated version. METHODS: The stage of translation and cross-cultural adaptation was performed according to an internationally accepted methodology, including the translation, back-translation, and pretest application of the translated version to a sample of 74 children to evaluate the degree of understanding. The reproducibility of the translated scale was assessed by applying the final version of Brazilian Portuguese modified Bristol Stool Form Scale for children to a sample of 64 children and 25 healthcare professionals, who were asked to correlate a randomly selected description from the translated scale with the corresponding representative illustration of the stool type. RESULTS: The final version of Brazilian Portuguese modified Bristol Stool Form Scale for children were evidently reproducible, since almost complete agreement (k>0,8) was obtained among the translated descriptions and illustrations of the stool types, both among the children and the group of specialists. The Brazilian Portuguese modified Bristol Stool Form Scale for children was shown to be reliable in providing very similar results for the same respondents at different times and for different examiners. CONCLUSION: The Brazilian Portuguese modified Bristol Stool Form Scale for children is reproducible; it can be applied in clinical practice and in scientific research in Brazil.

Combinations of laxatives and green banana biomass on the treatment of functional constipation in children and adolescents: a randomized study.

OBJECTIVES: Evaluate the effect of combinations of green banana biomass and laxatives in children and adolescents with chronic constipation. METHODS: This was a randomized study of 80 children and adolescents with functional constipation according to the Rome IV Criteria, who were divided into five groups: (1) green banana biomass alone; (2) green banana biomass plus PEG 3350 with electrolytes; (3) green banana biomass plus sodium picosulfate; (4) PEG 3350 with electrolytes alone; and (5) sodium picosulfate alone. Primary outcome measure was the reduction of the proportion of patients with Bristol Stool Form Scale ratings 1 or 2. Secondary outcome measures were: increase of the proportion of >3 bowel movements/week and reduction of the proportion of fecal incontinence, straining on defecation, painful defecation, blood in stool, abdominal pain, and decreased laxative doses. RESULTS: On consumption of green banana biomass alone, a statistically significant reduction was observed in the proportion of children with Bristol Stool Form Scale rating 1 or 2, straining on defecation, painful defecation, and abdominal pain. Conversely, no reduction was observed in fecal incontinence episodes/week, blood in stool, and no increase was observed in the proportion of children with >3 bowel movements/week. The percentage of children who required decreased laxative dose was high when green banana biomass was associated with sodium picosulfate (87%), and PEG 3350 with electrolytes (63%). Green banana biomass alone and associated with laxatives was well tolerated, and no adverse effects were reported. CONCLUSION: Green banana biomass is advantageous as an adjunct therapy on functional constipation, mainly for reducing doses of laxatives.
