Educar em saúde: conhecendo as principais doenças do intestino

 O câncer colorretal apresenta elevada taxa de incidência na população brasileira e é o quinto tipo de câncer em mortalidade no país. Outras doenças intestinais, como a diverticulite, a apendicite e as hemorroidas, também são bastante comuns, responsáveis por grande parte dos atendimentos em unidades de urgência e emergência. A fim de alertar a população e estimular a prevenção das doenças intestinais e do câncer colorretal, foi desenvolvida uma atividade de extensão universitária que ocorreu a partir de visitas de adultos e crianças ao "Intestino Gigante", que é uma réplica de intestino grosso, de tamanho suficientemente grande para permitir um passeio informativo em seu interior. As visitas foram supervisionadas por alunos de graduação e de pós-graduação, previamente treinados para discutir sobre os temas abordados com os participantes. Dois mil e vinte e sete visitantes participaram da atividade, durante os 5 dias de exposição. Cento e trinta e um visitantes responderam questionários para avaliação de conhecimentos antes e após a visitação. Cinquenta e um participantes responderam ao questionário específico sobre câncer colorretal e 80 responderam ao questionário específico sobre outras doenças intestinais. Houve aumento do significativo do conhecimento, antes e após as visitas, para os dois questionários utilizados. O conhecimento prévio dos participantes era significativamente maior em relação ao câncer colorretal do que em relação às doenças do intestino. Por outro lado, o ganho de conhecimento foi significativamente superior para as perguntas relacionadas às doenças do intestino do que ao câncer colorretal, fazendo com que esta diferença deixasse de apresentar significância estatística no momento pós-visita. A evolução de ganho de conhecimento não demonstrou diferença estatisticamente significativa entre as diferentes faixas etárias. A atividade de extensão universitária proposta foi considerada eficaz, promovendo educação em saúde pela difusão de conhecimentos para a comunidade, abordando as principais doenças do intestino e incentivando a prevenção, diagnóstico precoce e melhora do tratamento

A ingestão de substâncias cáusticas na infância: A construção e divulgação de vídeo educativo sobre medidas de prevenção / The ingestion of caustic substances in childhood: The construction and dissemination of an educational video on prevention measures

A ingestão de substâncias cáusticas na infância é um problema de saúde pública e acarreta alta morbidade aos pacientes, que geralmente desenvolvem estenose esofágica. Os tratamentos disponíveis para estenose cáustica são pouco satisfatórios e por isso realizamos um trabalho para divulgação de medidas de prevenção. Trata-se de vídeo explicativo sobre os perigos da ingestão de substâncias cáusticas e como evitar tais acidentes com crianças. O vídeo foi produzido a partir do relato de familiares de pacientes vítimas da ingestão acidental de soda cáustica

Desafios diagnósticos na doença de Hirschsprung: aplicabilidade de novos métodos imunohistoquímicos e endoscópicos

A identificação pré-operatória da zona de transição na Doença de Hirschsprung (DH) tornou-se um passo fundamental para o planejamento cirúrgico, especialmente para a técnica de abaixamento endorretal transanal. O presente estudo tem como objetivo investigar prospectivamente o valor da determinação colonoscópica da zona de transição na avaliação pré-operatória dos pacientes com DH. A colonoscopia foi realizada em doze pacientes com diagnóstico de DH previamente confirmado pela manometria anorretal, enema opaco e biópsia de sucção do reto. Endoscopicamente, o primeiro local com ausência de peristaltismo foi identificado como o início da zona agangliônica. Pouco acima deste ponto, a zona de transição foi marcada através de uma tatuagem com tinta nanquim. Durante o abaixamento endorretal transanal, uma biópsia de congelação envolvendo a espessura total da parede foi sempre realizada. Os resultados da determinação colonoscópica da zona de transição foram comparados com os obtidos pelo enema opaco. A colonoscopia permitiu a identificação da zona de transição em todos os 12 casos (100%). O enema opaco revelou a presença da zona de transição em apenas 7 pacientes (58,3%). A análise das amostras de congelação, obtidas pouco acima das áreas endoscopicamente marcadas, revelou a presença de células ganglionares em todos os casos. A análise histopatológica das peças cirúrgicas confirmou o diagnóstico de DH em todos os casos, assim como a localização da zona de transição no mesmo local previamente tatuado endoscopicamente. O exame colonoscópico pré-operatório demonstrou ser uma ferramenta útil para determinar a localização da zona de transição em pacientes com DHPreoperative identification of the transition zone in Hirschsprung’s disease (HD) has become an essential issue for surgical planning, especially for Transanal Endorectal Pull- Through (TEPT) procedure. The present study aimed to investigate prospectively, the value of endoscopic marking of the transition zone between normal and aganglionic bowel, as a landmark of the location of pull-through procedure for treatment of HD. Colonoscopy was performed on twelve patients with HD diagnosis, previously confirmed by anorectal manometry, contrast enema and rectal suction biopsies. Endoscopically, the first site with absence of motility was identified as the beginning of the aganglionic area. Just above this point, the transition zone was marked with an Indian Ink tattooing. During the TEPT, a full-thickness biopsy for frozen section analysis was performed just above this mark. The results of colonoscopic making were compared with contrast enema. Colonoscopy allowed the identification and tattooing of the junction between normal bowel with peristalsis and aganglionic bowel without peristalsis in all 12 cases (100%). Barium enema revealed the transition zone in 7 patients (58.3%). Frozen samples, obtained just above the marked areas revealed the presence of ganglion cells in all cases and the histopathological analysis of surgical specimens confirmed the diagnosis of HD in all cases and checked the location of the transition zone at the same site previously identified by colonoscopy. Colonoscopic marking of the transition zone may be a useful tool to set the location of pull-through procedure for treatment of HDCoordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES

The correlation between students’ progress testing scores and their performance in a residency selection process

Brazil is currently seeing an increased number of medical schools, leading to high competition for medical residency vacancies. Public managers have thus considered Progress Testing scores potentially useful as part of the final decision in the medical residency selection process. We analyzed whether there is a correlation between students’ Progress Testing scores and their performances in medical residency selection. We examined four subsequent cohorts of students who attempted Progress Testing yearly and compared their accumulated scores with their medical residency selection scores from Botucatu Medical School, Universidade Estadual Paulista. We included 212 students who finished the 6-year medical course in 2013, 2014, 2015, and 2016. The comparison between the area under the Progress Testing curve and the medical residency selection score was performed using a Pearson correlation, with a p value set at < 0.05. We found a positive association between the two scores (p < 0.05 for the 4 years). Next, the students were grouped according to their performance in Progress Testing: above one, within one, and below one standard deviation. A chi-square test was used to compare the rates of approval with the second step of the medical residency selection process. Approval rates were 91.7%, 69.2%, and 42.1%, respectively (p < 0.05). We conclude that, in fact, there is a correlation between students’ performance on these measures. This is partially explained by the fact that both instruments measure cognitive competencies and knowledge. These data may support national policy changes for medical residency selection2941071107

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. 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.

The Diagnostic Capacity of Physical Examinations in Diagnosing Musculoskeletal Disorders of the Lower Limbs in Children with Down Syndrome

Background and Objectives: although musculoskeletal alterations are common in patients with Down syndrome (DS), studies investigating this association are scarce, and proposals for diagnostic standardization are limited. We aimed to evaluate the prevalence of musculoskeletal disorders in the lower limbs in a sample of children and adolescents with DS and to investigate the diagnostic capacity of orthopedic clinical examinations performed by orthopedists and pediatricians to diagnose these alterations. Materials and Methods: Twenty-two patients aged between three and ten years with DS were included. Patients and guardians answered a simple questionnaire regarding orthopedic complaints and underwent a systematic orthopedic physical examination, performed twice: once by an orthopedist and again by a pediatrician. Patients underwent a series of radiographs to diagnose anisomelia, hip dysplasia, epiphysiolysis, flatfoot valgus, mechanical axis varus, and mechanical axis valgus. The radiological diagnosis was considered the gold standard, and the diagnostic capacity of the physical examination performed by each physician was determined. Results: The median age was 6.50 years. Only four patients (18.2%) presented with orthopedic complaints. All patients were diagnosed with at least one musculoskeletal disorder. The only musculoskeletal disorder with a good diagnostic capacity was flatfoot valgus. Limited sensitivity values were found for hip dysplasia, mechanical axis varus, and mechanical axis valgus. The agreement between the orthopedic physical examinations performed by the two examiners was weak, poor, or indeterminate for most of the analyzed items. Conclusions: There was a high prevalence of orthopedic alterations in children with DS who did not present with musculoskeletal complaints. The diagnostic capacity of the physical examination was limited. Therefore, all children with DS should undergo a radiological evaluation of the musculoskeletal system and subsequent specialized orthopedic evaluation. Level of Evidence: Level II (Diagnostic Studies)

A useful panel for the diagnosis of Hirschsprung disease in rectal biopsies: calretinin immunostaining and acetylcholinesterase histochesmistry

The pathological evaluation of rectal biopsies for the diagnosis of Hirschsprung disease has been a challenging issue. We analyzed prospectively the usefulness of calretinin immunostaining and acetylcholinesterase (AChE) histochesmistry in rectal biopsies for the diagnosis of Hirschsprung disease. Frozen tissue samples from 43 patients were used for AChE histochemistry and paraffin-embedded sections for calretinin immunohistochemistry and conventional histology (hematoxylin and eosin [H&E]). Activity for AChE, was demonstrated in 13 of 43 cases, and the absence of immunoreactivity for calretinin was observed in 14 of 43 cases. Conventional histology (H&E) did not reveal ganglion cells in 24 of 43 cases. The results on calretinin were in good agreement with AChE according to the κ index (0.946; P < .001) and presented significantly higher specificity (96.7 × 63.3; P < .002) and accuracy (97.6 × 74.4; P < .003) when compared with conventional histology (H&E). The final diagnosis of Hirschsprung disease was confirmed in 13 of 43 patients who were submitted to surgical treatment. The results of the present study indicate that calretinin can be a good tool in ruling out the diagnosis of Hirschsprung disease, by showing positive staining in ganglion cells and intrinsic nerve fibers, whereas AChE is useful in confirming the diagnosis of Hirschsprung disease, by revealing activity of this enzyme in hypertrophied nerve fibers. The association between calretinin and AChE can be a useful panel for the histopathologic evaluation of rectal biopsies for the diagnosis of Hirschsprung disease. © 2013 Elsevier Inc.

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

The use of mitomycin C in caustic esophagitis in rats

PURPOSE: To evaluate the topical effects of mitomycin C (MMC) in rats, with or without esophageal dilation, in different moments after esophageal caustic injury with NaOH10%. METHODS: Forty eight Wistar rats were divided into six groups: "GS" infusion of 0.9% saline solution in the esophagus; "CG" infusion of 0.9% saline solution in the esophagus, with temporary ligation of the organ; "NTG" induction of a caustic lesion without treatment; "GmmcD0" MMC applied immediately after the caustic injury; "GmmcD14" MMC applied 14 days after the caustic injury; "Gdil+mmcD14" esophageal dilation and application of MMC 14 days after caustic injury. We performed contrast esophagograms of four animals from each group, seven and 21 days after the caustic injury. On day 28, all animals were sacrificed, and histopathological analyses were performed on the esophageal specimens. RESULTS: The contrast images showed total stenosis in NTG and GmmcD0, improving to partial stenosis in GmmcD0. In GmmcD14 and Gdil+mmcD14, two animals of each group improved to partial stenosis. By histopathological analysis, NTG and GmmcD14 presented intermediate damage and GmmcD0 and Gdil+mmcD14 severe damage. CONCLUSION: The use of mitomycin C had beneficial effects specially when applied immediately after the induction of esophageal lesions
