RESUMEN
AIMS: To determine the level of agreement between healthcare professionals, patients and their parents/guardians in the interpretation of the urine color scale (UCS) in cases of urinary dysfunction, analyzing the applicability of the scale as a diagnostic tool determining the hydration status. METHODS: This was a cross-sectional study involving 5-17-year-old patients with lower urinary tract symptoms (LUTS) and enuresis. The study was conducted in a public healthcare referral center for pediatric urology in the Brazilian state of Bahia between October 2019 and March 2020. The Kolmogorov-Smirnov test was used to assess the distribution of the variables. Agreement was assessed using the kappa coefficient and weighted kappa. The z-test was used to determine significant differences between the kappa and weighted kappa. The statistical analysis was conducted using SPSS, version 14, and significance was established at p < 0.05. RESULTS: Forty-four patients were included. The kappa value was 32.4% (p = 0.000) for the agreement between healthcare professionals and patients, 41.9% (p = 0.000) for agreement between healthcare professionals and parents/guardians, and 25.0% (p = 0.001) for agreement between patients and parents/guardians. The weighted kappa was 70.6% (p = 0.000) for agreement between healthcare professionals and patients, 82.4% (p = 0.000) for agreement between healthcare professionals and parents/guardians, and 51.5% (p = 0.001) for agreement between patients and parents/guardians. There was a statistically significant difference in kappa values when the healthcare professionals were compared with the other groups. CONCLUSIONS: Although there were some inconsistencies in interpretation, the UCS proved to be a useful tool with which to evaluate patients' hydration status.

ABSTRACT Purpouse: One of the many artificial intelligence based tools that has gained popularity is the Chat-Generative Pre-Trained Transformer (ChatGPT). Due to its popularity, incorrect information provided by ChatGPT will have an impact on patient misinformation. Furthermore, it may cause misconduct as ChatGPT can mislead physicians on the decision-making pathway. Therefore, the aim of this study is to evaluate the accuracy and reproducibility of ChatGPT answers regarding urological diagnoses. Materials and Methods: ChatGPT 3.5 version was used. The questions asked for the program involved Primary Megaureter (pMU), Enuresis and Vesicoureteral Reflux (VUR). There were three queries for each topic. The queries were inserted twice, and both responses were recorded to examine the reproducibility of ChatGPT's answers. Afterwards, both answers were combined. Finally, those rwere evaluated qualitatively by a board of three specialists. A descriptive analysis was performed. Results and Conclusion: ChatGPT simulated general knowledge on the researched topics. Regarding Enuresis, the provided definition was partially correct, as the generic response allowed for misinterpretation. For VUR, the response was considered appropriate. For pMU it was partially correct, lacking essential aspects of its definition such as the diameter of the dilatation of the ureter. Unnecessary exams were suggested, for Enuresis and pMU. Regarding the treatment of the conditions mentioned, it specified treatments for Enuresis that are ineffective, such as bladder training. Therefore, ChatGPT responses present a combination of accurate information, but also incomplete, ambiguous and, occasionally, misleading details.

BACKGROUND: The Rome IV criteria are used to characterize constipation and its subtypes, but not its severity. Conversely, the constipation scoring system (CSS) is a tool designed to assess the level of constipation severity and assist clinicians in selecting suitable therapeutic strategies. Although validated for adults, this score has yet to be validated for children. OBJECTIVE: To adapt and validate the CSS for the pediatric population. METHODS: Children and adolescents of 4-17 years of age with no morphological or neurological abnormalities of the gastrointestinal system were randomly selected during general consultation with a pediatrician and evaluated between November 2021 to April 2022. The Rome IV criteria were considered the gold-standard detection method. The adapted version was initially assessed on 30 children to assess comprehension and then administered to another 100 children. The internal consistency of the adapted questionnaire was assessed in a test-retest procedure with a two-week interval. RESULTS: One hundred patients with a mean age of 8.61 ± 3.25 years were assessed. Of these, 51 (51 %) were male. Most children (n = 91) received a score of 1-10 (the total CSS score can range from 0 to 30 points). The correlation between the pediatric version of the CSS and the Rome IV criteria was substantial, as shown by a positive Spearman correlation (r2) of 0.553 (p < 0.001). Cronbach's alpha between the test-retest responses was 0.97. When each item of the questionnaire was assessed individually, a greater level of internal consistency was found, indicating adequate internal reliability. DISCUSSION: The current study broadens the horizon with the emergence of new diagnostic aid for FC in Brazilian children and adolescents. In addition, this study provides the cornerstone for future research to determine the diagnostic accuracy of the CSS and its prognostic value for monitoring the treatment. The loss of a follow-up rate (26 %) during the telephone "test-retest" phase was a limitation. Using a subjective questionnaire such as the Rome IV criteria as the gold standard method may also represent a limitation. Further research is required on the use of objective diagnostic tools for FC including colonic transit time, anal manometry, cine-defecography, and electromyography. CONCLUSION: The CSS was successfully adapted for use with the pediatric population and was well accepted, confirming its language and psychometric validity in aiding the diagnosis of functional constipation. This was the first step towards validating the use of this score in other countries and cultures to assess the severity of constipation in children.

Abstract Introduction Constipation is a common clinical condition, particularly among cancer patients. Objective To assess the prevalence and severity of CF in women with high-grade intraepithelial neoplasia (HSIL) and cervical cancer (CC), as well as the impact of this condition on their daily lives. Methods A cross-sectional study was conducted at a tertiary cancer center. To assess the presence and severity of constipation, the Rome IV criteria, and the Constipation Scoring System (CSS) were used. To assess the impact of constipation on daily life, the Visual Analogue Scale (VAS) was used. Results The study included 153 patients with HSIL or CC, with a median age of 44 (IQR 35-56) years. Constipation was reported in 54 (35.3%) patients, 33 (61.1%) of those with HSIL, and 21 (38.9%) of those with CC. In constipated patients, the median number of positive Rome IV criteria items was 3 (IQR 2-5). "Irregular or hard stools" was the most common complaint, affecting 41 (75.9%) of the patients. In patients with CC, the use of analgesic medications was associated with constipation (p = 0.016). There is no link between constipation and invasive cancer (p = 0.492). Constipation had a daily impact of 7.5 (IQR 4.75-9), with no relationship between VAS and clinical diagnosis (HSIL or CC) [7 (IQR 3-9) X 8 (5-9.5), p-value = 0.536] The more severe the constipation, the more disturbing it is to these women's daily lives. Conclusion Constipation is common in women with cervical lesions, affecting their daily lives regardless of their severity.
RESUMEN
ABSTRACT Purpose: Parasacral Transcutaneous Electrical Stimulation (TENS) is one of the treatments for children with Bladder and Bowel Dysfunction (BBD). Some studies showed that children with increased Rectal Diameter (RD) have more Functional Constipation (FC). However, RD prediction in maintenance of BBD after treatment was never evaluated. Our aim is to evaluate the association between RD and response to treatment in children and adolescents with BBD. Materials and Methods: This study evaluated patients from 5-17 years old with BBD. Dysfunctional Voiding Scoring System (DVSS), Rome IV criteria, and the Constipation Score were used. RD was measured using abdominal ultrasound before treatment according to the technique established by Klijn et al. and was considered enlarged when >3cm. No laxatives were used during treatment. Descriptive analysis and binary regression were performed and the area under the ROC curve was calculated. Results: Forty children were included (mean age 8.4±2.8 years, 52.5% male). Before treatment, RD was enlarged in 15 children (37.5%) (mean diameter 3.84±0.6cm), with FC persisting post-treatment in 11/15(73.3%). Those patients also required more laxatives following treatment and had more severe FC. Binary regression showed pretreatment RD to be an independent predictor of the persistence of FC post-treatment (OR=9.56; 95%CI:2.05-44.60). In ROC curve analysis, the sensitivity was 100% (95%CI: 0.49-1.0) and specificity 77.14% (95%CI:0.60-0.90) for rectal diameter >3 cm. The likelihood ratio was 4.38 (95%CI:2.40-8.0) for the persistence of BBD following treatment. Conclusion: RD appears to be relevant in the evaluation of children with BBD, not only as a diagnostic tool but also as a predictor of treatment outcome.
RESUMEN
Abstract Background Argon plasma coagulation (APC) is a non-tactile ablative therapy that helps to stop rectal bleeding in patients who have developed actinic proctitis after exposure to radiotherapy. This approach seems to be more effective than medications or surgical procedures. Objective To review the literature to verify the effectiveness of APC in the treatment of patients with actinic proctitis induced by radiation therapies. Methods A systematic search was conducted on the following databases: MEDLINE/PubMed, LILACS, SCIELO, and the Cochrane Central Register of Controlled Trials. We identified 81 studies, and 5 of them fulfilled the inclusion criteria. Results In the articles included, a total of 236 patients were evaluated. Most of them were men (67.7%) with a mean age of 66.6 years. Prostate cancer was the main cause of actinic proctitis (67.3%), and control of the bleeding was achieved in 83.3% of the cases, after a mean of 1.67 session of APC. Moreover, 66 patients had complications with the treatment, and rectal pain was the most referred. Conclusions Argon plasma coagulation is a well-tolerated and effective treatment to control rectal bleeding in patients who underwent radiotherapy, and the number of sessions varies from 1 to 2, according to the case.

ABSTRACT Background Beyond Rome IV Criteria, the assessment of functional constipation in clinical practice can also be obtained by the Constipation Scoring System (CSS). By accessing the CSS, health professionals are able to measure this dysfunction, guiding initial therapeutic approach and post-treatment response. In addition, the CSS enables the standardization of results concerning functional constipation research. Objective To promote translation, cross-cultural adaptation and validation of the CSS for the Brazilian population. Methods To attain the score in Portuguese, the adaptation was accomplished in four steps (translation, back translation, application and adjustments). Afterward, the validation and adaptation to the Brazilian population was performed through test-retest. Results For adults, the convergent validity of the Brazilian version of the CSS showed a significant correlation to the Rome IV Criteria evinced by the positive Spearman correlation (r2) of 0.816 (P<0.001). Between the test-retest responses, the translated version of the score had a Cronbach's Alpha of 0.972. A high level of internal consistency was also obtained when each item of the questionnaire was assessed separately, revealing an adequate internal reliability Conclusion The CSS was well adapted and accepted by the Brazilian population, demonstrating the linguistic and psychometric validity of this Portuguese version of the score.
RESUMO Contexto Além dos Critérios de Roma IV, a avaliação da constipação funcional também pode ser obtida por meio do Constipation Scoring System (CSS). Ao acessar o CSS, o profissional de saúde consegue mensurar a constipação funcional, orientando a abordagem terapêutica inicial e a resposta pós-tratamento. Além disso, o CSS possibilita a padronização dos resultados das pesquisas sobre esta disfunção. Objetivo Promover a tradução, adaptação transcultural e validação do CSS para a população brasileira. Métodos Para obtenção da versão do CSS em português, a adaptação foi realizada em quatro etapas (tradução para o inglês, retrotradução para o português, aplicação e ajustes). Posteriormente, foi realizada a validação e adaptação para a população brasileira por meio de teste-reteste. Resultados Para adultos, a validade convergente da versão brasileira do CSS apresentou correlação significativa com os critérios de Roma IV evidenciada pela correlação de Spearman positiva (r) de 0,816 (P<0,001). Entre as respostas do teste-reteste, a versão traduzida do escore apresentou um Alpha de Cronbach de 0,972. Um alto nível de consistência interna também foi obtido quando cada item do questionário foi avaliado separadamente, revelando uma confiabilidade interna adequada. Conclusão O CSS foi bem adaptado e aceito pela população brasileira, demonstrando a validade linguística e psicométrica da versão em português do escore.
RESUMEN
Objective: To evaluate the association of fecal incontinence (FI) and lower urinary tract symptoms (LUTS) in patients diagnosed with initial prostate cancer (PC) and after any therapeutic approach (surgery and radiotherapy). Methods: Cross-sectional study using the Cleveland Clinic Incontinence Score (CCIS), the Fecal Incontinence Quality of Life (FIQL) questionnaire, and the International Consultation on Incontinence Questionnaire Overactive Bladder (ICIQ-OAB). Results: A total of 84 patients with PC were included: 40 of them had not started treatment, 31 were submitted to radical prostatectomy (RP), and 13 were submitted to radiotherapy (RT). Those submitted to RT presented higher scores on the ICIQ-OAB (p=0.01). When comparing the whole sample reagarding the patients with and without FI, we observed that the incontinents presented a higher frequency of urinary incontinence (UI) (p<0.001). Moreover, when comparing patients with/without FI within their treatment groups regarding the presence of UI and FIQL scores, we identified that patients undergoing RP presented an association between UI and FI (p<0.001) and a greater impact of FI on the FIQL (p<0.001). Conclusion: Patients submitted to RT present more intense LUTS. Moreover, patients with FI present a higher association with UI, and this association is more marked in those with FI submitted to RP.

ABSTRACT BACKGROUND: Recently it was shown an association between lower urinary tract symptoms in mothers and their children. However, the role of functional constipation in this binomial is unclear. OBJECTIVE: To evaluate bladder and bowel dysfunction between mothers and children. METHODS: A population-based cross-sectional study. Mothers and their children responded a self-administrated questionnaire composed by Rome IV criteria, International Consultation on Incontinence Questionnaire - Overactive Bladder, Dysfunctional Voiding Scoring System and demographic questions. RESULTS: A total of 441 mother-child pairs was obtained. Children's mean age was 9.1±2.7 years, with 249 (56.5%) female. Mothers' mean age was 35.7±6.1 years. Isolated constipation was present at 35 (7.9%) children and 74 (16.8%) mothers. Isolated lower urinary tract symptoms were present in 139 (31.5%) children and 92 (20.9%) mothers and bladder bowel dysfunction occurred in 51 (11.6%) children and 78 (17.7%) mothers. There wasn't any association between isolated lower urinary tract symptoms in children and isolated lower urinary tract symptoms in mothers (P=0.31). In univariate analysis there were an association between bladder bowel dysfunction in children and bladder bowel dysfunction in mothers (OR=4.8 IC 95% 2.6-9.6, P<0.001) and isolated constipation in children and isolated constipation in mothers (OR=3.0 IC 95% 1.4-6.4, P=0.003). In multivariate analysis mothers with bladder bowel dysfunction was the only independent factor associated with bladder bowel dysfunction in children (OR=5.4 IC 95% 2.5-11.6, P<0.001). CONCLUSION: Mothers with bladder bowel dysfunction are more likely to have a child with bladder bowel dysfunction. Association between these two dysfunctions plays an important role in this familiar presentation.
RESUMO CONTEXTO: Recentemente foi demonstrada associação entre sintomas do trato urinário inferior entre mães e filhos. No entanto, o papel da constipação funcional neste binômio não é claro. OBJETIVO: Avaliar a disfunção vésico-intestinal entre mães e filhos. MÉTODOS: Estudo transversal de base populacional. As mães e os filhos responderam a um questionário de autorresposta, composto pelos critérios de Roma IV, International Consultation on Incontinence Questionnaire - Overactive Bladder, Dysfunctional Voiding Scoring System e perguntas sociodemográficas. RESULTADOS: Foram estudados 441 pares mãe-filho. A idade média dos filhos foi de 9,1±2,7 anos, sendo 249 (56,5%) do sexo feminino. A idade média das mães foi de 35,7±6,1 anos. A constipação sem sintomas do trato urinário inferior estava presente em 35 (7,9%) crianças e 74 (16,8%) mães. Sintomas do trato urinário inferior isolados estavam presentes em 139 (31,5%) crianças e 92 (20,9%) mães e a disfunção vésico-intestinal ocorreu em 51 (11,6%) crianças e 78 (17,7%) mães. Não houve associação entre sintomas isolados do trato urinário inferior em crianças e sintomas isolados do trato urinário inferior em mães (P=0,31). Na análise univariada, houve associação entre disfunção vésico-intestinal em crianças e disfunção vésico-intestinal em mães (OR=4,8 IC 95% 2,6-9,6; P<0,001) e constipação isolada em crianças e constipação isolada em mães (OR=3,0 IC 95 % 1,4-6,4; P=0,003). Na análise multivariada, mães com disfunção vésico-intestinal foi o único fator de associação independente para disfunção vésico-intestinal em crianças (OR=5,4 IC 95% 2,5-11,6; P<0,001). CONCLUSÃO: Mães com disfunção vésico-intestinal têm maior probabilidade de ter filhos com disfunção vésico-intestinal. A associação entre constipação e sintomas do trato urinário inferior desempenha um papel importante nesta apresentação familiar.

ABSTRACT BACKGROUND: An association between urinary disorders and functional constipation has been registered in children and adults, with functional constipation being a common complaint in individuals with overactive bladder. OBJECTIVE: To evaluate the prevalence of functional constipation, overactive bladder and its dry/wet subtypes in women and to determine which bowel symptoms predict overactive bladder. METHODS: A cross-sectional study of women randomly approached in public spaces. Exclusion criteria: neurological/anatomical abnormalities of the bowel or urinary tract. Constipation was defined as ≥2 positive symptoms of those listed in the Rome criteria. Urinary abnormalities (frequent urination, urgency, incontinence, nocturia) were defined by a score ≥2 in the respective item of the International Consultation on Incontinence Questionnaire - Overactive Bladder. Dry overactive bladder was defined as urgency without incontinence, while wet overactive bladder included incontinence. RESULTS: A total of 516 women with a mean age of 35.8±6 years were interviewed. Rates of functional constipation, overactive bladder, dry overactive bladder and wet overactive bladder were 34.1%, 15.3%, 8.9% and 6.4%, respectively. Functional constipation was associated with overactive bladder and dry overactive bladder, with functional constipation predicting dry overactive bladder (OR=2.47). Quality of life was poorer in constipated women compared to non-constipated and even worse in constipated women with wet overactive bladder (median 22.5; 95%CI: 17.25-35.25). Manual maneuvers were significantly associated with both overactive bladder subtypes. Independent predictive factors for overactive bladder were manual maneuvers (OR=2.21) and <3 defecations/week (OR=2.18), with the latter being the only predictive factor for dry overactive bladder (OR=3.0). CONCLUSION: Functional constipation is associated with overactive bladder and its dry subtype, particularly in the younger population. In addition, this association is responsible for lower quality of life scores, especially when urinary incontinence is present. The presence of manual maneuvers and less than three defecations per week should direct us to look for overactive bladder.
RESUMO CONTEXTO: A associação entre distúrbios urinários e constipação funcional vem sendo observada em crianças e adultos, sendo a constipação funcional uma queixa comum em indivíduos com bexiga hiperativa. OBJETIVO: Avaliar a prevalência de constipação funcional, bexiga hiperativa e seus subtipos seco/úmido em mulheres e determinar quais os sintomas intestinais estão mais associados e são preditores de bexiga hiperativa. MÉTODOS: Estudo de corte transversal com mulheres abordadas aleatoriamente em locais públicos. Os critérios de exclusão foram: anormalidades neurológicas/anatômicas do intestino ou do trato urinário documentadas. A constipação foi definida como ≥2 sintomas positivos daqueles listados nos critérios de Roma. Alterações urinárias (frequência urinária aumentada, urgência, incontinência e noctúria) foram definidas por um escore ≥2 no respectivos itens do Questionário Internacional de Consulta sobre Incontinência - Bexiga Hiperativa. Foi denominada de bexiga hiperativa seca a presença de sintomas de urgência sem incontinência urinária e bexiga hiperativa úmida quando a urgência estava associada a incontinência urinária. RESULTADOS: Foram entrevistadas 516 mulheres com idade média de 35,8±6 anos. As taxas de constipação funcional, bexiga hiperativa, bexiga hiperativa seca e bexiga hiperativa úmida na amostra estudada foram de 34,1%, 15,3%, 8,9% e 6,4%, respectivamente. Foi observada associação entre constipação funcional e bexiga hiperativa / bexiga hiperativa seca, sendo a constipação funcional fator preditor para esse subtipo de bexiga hiperativa (OR=2,47). O escore de qualidade de vida foi pior nas mulheres com constipação funcional em comparação com as não constipadas e ainda pior nas mulheres com constipação funcional associada a bexiga hiperativa úmida (mediana 22,5; IC 95%: 17,25-35,25). A presença de manobras manuais estava significativamente associada aos dois subtipos de bexiga hiperativa. Os fatores preditivos independentes para bexiga hiperativa foram manobras manuais (OR=2,21) e <3 defecações/semana (OR=2,18), sendo este último o único fator preditivo para bexiga hiperativa seca (OR=3,0). CONCLUSÃO: Em mulheres, a constipação funcional está associada a bexiga hiperativa e seu subtipo seco, particularmente na população mais jovem. Além disso, essa associação é responsável por piores escores de qualidade de vida, principalmente quando a incontinência urinária está presente. A presença de manobras manuais e menos de três defecações por semana em mulheres devem nos direcionar a procurar por bexiga hiperativa.

Trabalhos demonstram associação entre níveis pré-operatórios elevados do antígeno carcinoembrionário (CEA) e prognóstico desfavorável. Este estudo tem como objetivo avaliar o valor prognóstico do CEA pré-operatório e a sua influência sobre recidiva da lesão, a sobrevida livre de eventos, a sobrevida total e o óbito relacionado a lesão. Os autores estudaram, retrospectivamente, 52 pacientes ( 27 homens e 25 mulheres ), média de idade de 58,02 anos, com Adenocarcinoma colorretal operados e acompanhados por até dois anos. Dois doentes apresentavam lesões Dukes A, vinte e três Dukes B, dezesseis Dukes C e onze Dukes D (Classificação de Dukes/ Astler Culler). Realizamos as dosagens do CEA pré-operatório por punção venosa de membros superiores e análise por enzimoimunoensaio monoclonal para valores normais inferiores a 7ng/ml em indivíduos fumantes e inferiores a 5ng/ml em indivíduos não fumantes. Foram encontrados valores elevados de CEA pré-operatório relacionados a uma menor sobrevida total ( 21,1 ± 6,2 meses CEA normal X 16,5 ± 8,3 meses CEA elevado),a uma sobrevida livre de eventos ( 18,9 ± 7,6 meses CEA normal X 13,7 ± 9,4 meses CEA elevado) e a um acompanhamento total ( 18,9 ± 12,6 meses CEA elevado X 27,3 ± 12,8 meses CEA normal) e a um maior número de óbitos. Na avaliação de recidiva tumoral não houve correlação entre as dosagens de CEA e esta variável. Conclui-se que neste estudo, níveis elevados de CEA no pré-operatório indicou um prognóstico desfavorável no que diz respeito a sobrevida total, sobrevida livre de eventos e óbito, não guardando, entretanto, relação com recidiva tumoral.
