Relationship between primary monosymptomatic enuresis and process toilet training: a case-control

ABSTRACT Objective: Primary monosymptomatic nocturnal enuresis (PMNE) is a prevalent condition in childhood, and the pathophysiology is multifactorial. This study investigated the relationship between the toilet training process (TT) and PMNE in children and adolescents. Patients and Methods: A case-control study was carried out from 2015 to 2020. The presence of PMNE was identified according to International Children's Continence Society criteria. A semi-structured questionnaire was applied to assess TT. Results: The study included 103 children and adolescents with PMNE and 269 participants with normal psychomotor development without PMNE (control group [CG]). Readiness signals were more remembered and less frequent in participants with PMNE (p=0.001) when compared to control group. No differences were found between the groups regarding the onset age of the daytime TT (p= 0.10), the nocturnal TT (p=0.08), the acquisition of daytime continence (p=0.06), and the type of equipment used for the TT (p=0.99). The use of Child-Oriented approach in group of children with enuresis was lower than in controls [87.4% (90/103) versus 94% (250/266)], respectively (OR= 0.44, 95% CI 0.21-0.94, p = 0.039). Conclusions: The age of onset of TT, acquisition of daytime continence, and the type of equipment were not associated with higher occurrence of PMNE. On the other hand, the Child-Oriented approach was a protective factor for the occurrence of PMNE.

Evaluating TIMP-2 and IGFBP-7 as a predictive tool for kidney injury in ureteropelvic junction obstruction

ABSTRACT A major challenge in the management of ureteropelvic junction obstruction (UPJO) is the selection of patients who would benefit from surgical treatment. Tissue inhibitor metalloproteinase-2 (TIMP-2) and insulin-like growth factor-binding protein 7 (IGFBP7) indicate renal cell stress and are associated with cell cycle arrest. The [TIMP-2] [IGFBP7] ratio (Nephrocheck®) has been recently applied in patients in intensive care units patients to predict the development of acute kidney injury. In this study, we evaluated the performance of these biomarkers performance to distinguishing obstructive hydronephrosis (HN) from non-obstructive HN. Materials and Methods: Consecutive patients with UPJO were enrolled in this study. Urinary [TIMP-2] [IGFBP7] and clinical characteristics (hydronephrosis grade, differential renal function, and drainage half-time) were measured in the following groups: 26 children with obstructive HN at initial diagnosis (group 1A) and after six months of dismembered pyeloplasty (group 1B); 22 children with non-obstructive HN (group 2), and 26 children without any urinary tract condition, as the control group (group 3). Results: Comparing the initial samples, [TIMP-2] [IGFBP7] had higher levels in the HN groups and lower levels in the control group; however, no difference was observed between the HN groups (obstructive vs. non-obstructive). After six months of follow-up, patients who underwent dismembered pyeloplasty showed stability in the urinary concentration of [TIMP-2] [IGFBP7]. All patients with [TIMP-2] [IGFBP7] higher than 1.0 (ng/mL)2/1000 had diffuse cortical atrophy on ultrasonography. Conclusions: We showed that urinary levels of urinary [TIMP-2] [IGFBP7] are higher in children with HN than controls. Nephrocheck® is not reliable in predicting the need for surgical intervention for pediatric patients with UPJO.

Calf circumference is an independent predictor of postoperative complications in the surgical treatment of head and neck cancer

INTRODUCTION: The prevalence of malnutrition is high among head and neck cancer (HNC) patients and negatively impacts their quality of life, treatment, and survival rates. OBJECTIVE: To identify preoperative nutritional variables capable of predicting postoperative complications in surgically treated HNC patients. METHODS: This was a prospective cohort study of HNC patients referred for surgery as initial treatment. RESULTS: Sixty patients were included in the study; they had a median age of 65.5 years, were mostly me n (85%), and most had low education levels (90%) and low household income (78.3%). The incidence rate of severe postoperative complications (grades II, III, IV, and V according to the Clavien-Dindo grading system) was found to be 50%. The nutritional variables under investigation, namely calf circumference (CC), triceps skinfold, body mass index, and adductor pollicis muscle thickness were shown to predict postoperative complications in HNC patients, especially CC, which was found to be an independent predictor of complications (OR=0.8; 95%CI: 0.65­0.96). Each 1-cm increase in calf circumference was associated with a 20% decrease in the risk of postoperative complications. CONCLUSION: Our findings show the nutritional variables studied are useful in the prognostic assessment of HNC surgery.

Early postoperative serum albumin levels as predictors of surgical outcomes in head and neck squamous cell carcinoma / Níveis de albumina sérica no pós‐operatório imediato como preditivo de resultados cirúrgicos em carcinoma de células escamosas de cabeça e pescoço

Abstract Background Malnutrition is a common issue in patients with head and neck squamous cell carcinoma and has a negative effect on surgical outcomes. Objective We attempted to determine which malnutrition diagnostic variables can be used as predictors of postoperative complications in patients with head and neck squamous cell carcinoma. Methods Forty-one patients undergoing surgery for head and neck squamous cell carcinoma were submitted to a prospective evaluation. Biochemical data, anthropometric measurements and evaluation of body composition were used in the nutritional analysis. Results Twenty-two patients (53.6%) developed complications. Serum albumin measured on the first postoperative day was the only variable that significantly differed between groups. A cut-off value of 2.8 g/dL distinguished between patients with a complicated and uncomplicated postoperative course. Normalization of albumin levels occurred more frequently and more rapidly in the noncomplicated group. Conclusion Serum albumin measured on the first postoperative day was the only variable that was a predicter of postoperative complications after major head and neck squamous cell carcinoma surgery.

Resumo Introdução A desnutrição é um problema comum em pacientes com carcinoma de células escamosas de cabeça e pescoço e tem um efeito negativo nos resultados cirúrgicos. Objetivo Tentamos determinar quais variáveis diagnósticas de desnutrição podem ser usadas como preditivos de complicações pós‐operatórias em pacientes com carcinoma de células escamosas de cabeça e pescoço. Método Quarenta e um pacientes submetidos à cirurgia de carcinoma de células escamosas de cabeça e pescoço foram submetidos a uma avaliação prospectiva. Dados bioquímicos, medidas antropométricas e avaliação da composição corporal foram usados na análise nutricional. Resultados Vinte e dois pacientes (53,6%) desenvolveram complicações. A dosagem de albumina sérica no primeiro dia pós‐operatório foi a única variável que diferiu significantemente entre os grupos. Um valor de corte de 2,8 g/dL distinguiu os pacientes com uma evolução pós‐operatória complicada e não complicada. A normalização dos níveis de albumina ocorreu mais frequentemente e mais rapidamente no grupo sem complicação pós‐operatória. Conclusão A albumina sérica medida no primeiro dia pós‐operatório foi a única variável capaz de predizer complicações pós‐operatórias após cirurgia de carcinoma de células escamosas de cabeça e pescoço de grande porte.

Arterial lactate as a predictor of postoperative complications in head and neck squamous cell carcinoma / Lactato arterial como preditor de complicações pós‐operatórias no carcinoma epidermoide de cabeça e pescoço

Abstract Introduction Surgery is one of the most frequently used options in the treatment of head and neck squamous cell carcinoma. In surgical patients, the use of arterial lactate to assess hypoxemia and severe inflammatory states is well-founded. However, there are few studies on its use in patients with head and neck squamous cell carcinoma. The aim of this study was to investigate whether the serum arterial lactate level on the 1st postoperative day would be a predictor of postoperative complications in head and neck squamous cell carcinoma surgeries. Methods This is a prospective cohort, which evaluated 44 adult patients of both genders, with HNSCC, who underwent surgery associated with monobloc neck dissection as an initial treatment. Patients were divided into two groups, according to the presence or absence of postoperative complications: with complication (Clavien-Dindo II-V) and without complications (Clavien-Dindo 0-I). Student's t-test and its variants were used to compare continuous data. Pearson's or Spearman's test was used to correlate the data and p values ​​<0.05 were considered statistically significant. Results A total of 59% of the patients (n = 26/44) developed postoperative complications. Serum lactate was significantly higher in the group with complications when compared to patients without complications, respectively 2.15 mmoL/L (1.10-3.90) and 1.59 mmoL/L (0.70-3.44); p = 0.03. The prognostic accuracy of arterial lactate was 69% (95% CI: 54%-82%; p = 0.03), estimated by the ROC curve. A cut-off >1.7 mmoL/L was identified, with a sensitivity of 65.38% and specificity of 66.67%. Conclusion Arterial lactate measured on the first postoperative day is a good predictor of postoperative complications in patients with head and neck squamous cell carcinoma.

Resumo Introdução A cirurgia é uma das opções mais usadas no tratamento do carcinoma epidermoide de cabeça e pescoço. Nos pacientes cirúrgicos, o uso do lactato arterial para avaliação de hipoxemia e de quadros inflamatórios graves é bem fundamentado. Entretanto, existem poucos estudos sobre o seu uso em pacientes com carcinoma epidermoide de cabeça e pescoço. O objetivo deste estudo foi investigar se o lactato arterial sérico no 1° dia de pós‐operatório seria um preditor de complicações pós‐operatórias nas cirurgias do carcinoma epidermoide de cabeça e pescoço. Método Trata‐se de uma coorte prospectiva, que avaliou 44 pacientes adultos, de ambos os gêneros, com carcinoma epidermoide de cabeça e pescoço, submetidos a cirurgia associada ao esvaziamento cervical em monobloco como tratamento inicial. Os pacientes foram divididos em dois grupos, segundo a presença ou não de complicações pós‐operatórias: complicados (Clavien‐Dindo II a V) e sem complicações (Clavien‐Dindo 0-I). Na comparação dos dados contínuos, foi usado o teste t de Student e as suas variantes. Na correlação dos dados, usou‐se o teste de Pearson ou Spearman. Valores de p inferiores a 0,05 (p < 0,05) foram considerados estatisticamente significativos. Resultados Dos pacientes, 59% (n = 26/44) desenvolveram complicações pós‐operatórias. O lactato sérico foi significantemente maior no grupo com complicações em relação aos pacientes sem complicações, respectivamente 2,15 mmoL/L (1,10-3,90) e 1,59 mmoL/L (0,70-3,44); p = 0,03. A acurácia prognóstica do lactato arterial foi de 69% (95% IC 54%-82%; p = 0,03), estimada pela curva ROC. Foi identificado um cut‐off> 1,7 mmoL/L, com sensibilidade de 65,38% e especificidade de 66,67%. Conclusão O lactato arterial do primeiro dia de pós‐operatório é um bom preditor de complicações pós‐operatórias nos pacientes com carcinoma epidermoide de cabeça e pescoço.

Association between Attention Deficit Hyperactivity Disorder and lower urinary tract symptoms in children and adolescents in a community setting

ABSTRACT Introduction: The present study aims to investigate the prevalence of lower tract urinary symptoms (LUTS) and symptoms of attention-deficit/hyperactivity disorder (ADHD) in children and adolescents and their association in a community setting using validated scoring instruments. Materials and Methods: A cross-sectional study was carried out from February 2015 to December 2019, during which the parents or guardians of 431 children and adolescents from 5 to 13 years of age, attending a general pediatric outpatient clinic were interviewed. Results: The prevalence of ADHD symptoms and LUTS were 19.9% and 17.9%, respectively. Of the 82 children and adolescents with ADHD, 28% (23) had LUTS (OR 2.31, 95% CI 1.28 to 3.75, p=0.008). Mean total DVSS score in children in the group of children presenting ADHD symptom was significantly higher than those without ADHD symptom (10.2±4.85 vs. 4.9±2.95, p=0.002). Urgency prevailed among LUTS as the most frequent symptom reported by patients with ADHD symptoms (p=0.004). Analyzing all subscales of the DVSS, the items "When your child wants to pee, can't he wait? "Your child holds the pee by crossing his legs, crouching or dancing?" were higher in those with ADHD symptoms (p=0.01 and 0.02, respectively). Functional constipation was present in 36.4% of children with LUTS and 20.7% without LUTS (OR 4.3 95% CI 1-5.3 p=0.001). Conclusion: Children and adolescents with ADHD symptoms are 2.3 times more likely to have LUTS. The combined type of ADHD was the most prevalent among them.

Luts-V: A new simplified score for assessing lower urinary tract symptoms in men

ABSTRACT Objectives: Develop and validate a new and simplified score for evaluating the lower urinary tract symptoms in men. Materials and methods: We modified the existing visual prostate symptom score, including changes in the images, sequence, and new alternatives, resulting in a new visual score (LUTS visual score-LUTS-V). For the validation of the new tool, we used the International Prostatic Symptom Score as the gold-standard and the new LUTS-V to 306 men. The total IPSS score and the total LUTS-V score of each subject were evaluated to determine the agreement between the two instruments. ROC curve was used to evaluate the diagnostic accuracy and best cut-off of LUTS-V. Sensitivity, specificity, and diagnostic odds ratios were used to describe the diagnostic properties. Results: The mean age of the participants was 59 [52-87] years. There was a significant correlation between LUTS-V and IPSS. (r=0.72 (p <0.0001). The Bland-Altman analyzes demonstrate good agreement between the two questionnaires (bias=5.6%). LUTS-V demonstrated excellent diagnostic accuracy in detecting the most serious cases with an area under the ROC curve of 83% [78-87%] 95% CI. p <0.001). LUTS-V >4 was the best threshold, with a sensitivity of 74% and specificity of 78%. Conclusions: LUTS-V is a simple, self-administered tool with a significant discriminatory power to identify subjects with moderate to severe LUTS and may represent a useful instrument for the diagnosis and follow-up of men with urinary symptoms.

Breastfeeding technique and the incidence of nipple traumas in puerperal women attended in a city hospital: intervention study / Técnica de amamentar e a incidência de traumas mamilares em puérperas atendidas em um hospital municipal: estudo de intervenção

Abstract Objectives: to evaluate the effect of an intervention on the incidence of nipple trauma and the quality of breastfeeding technique in the first month of postpartum. Methods: this is a quasi-randomized intervention study with 180 puerperal women equally distributed between experimental and control groups. The intervention was performed at a maternity and consisted of an educational session on breastfeeding technique. A descrip-tive analysis of the groups' characteristics was performed, comparing the frequencies of unfa-vorable parameters related to breastfeeding technique between groups. Pearson's chi-square test and Fisher's test were used, and p≤0.05 was adopted as the critical level of significance. Results: at 30 days, 64% and 15% of the mothers used the technique correctly, respec-tively, in the experimental and control groups with RR=4.87 (CI95%=2.93-8.34); NNT=1.96 (CI95% =1.61-2.72); p<0.001. In the experimental group, a decrease was observed in the unfavorable parameters of the breastfeeding technique (p≤0.05). The incidence of nipple trauma was 30% in the experimental group and 38.9% in the control group (p=0.21). Conclusions: the intervention was insufficient to prevent nipple trauma in the experi-mental group, but significantly improved the quality in the breastfeeding technique.

Resumo Objetivos: avaliar o efeito de uma intervenção na incidência de traumas mamilares e na qualidade da técnica de amamentar no primeiro mês pós-parto. Métodos: trata-se de um estudo de intervenção quasi randomizado com 180 puérperas distribuídas entre os grupos experimental e controle. A intervenção foi realizada na mater-nidade e consistiu de sessão educativa sobre a técnica de amamentar. Foi realizada análise descritiva das características dos grupos, comparadas as frequências dos parâmetros desfa-voráveis da técnica de amamentar. O teste do qui-quadrado de Pearson e teste de Fisher foram utilizados, sendo adotado p≤ 0,05 como nível crítico de significância. Resultados: aos 30 dias, 64% e 15%, das mães apresentaram técnica correta, respectiva-mente, nos grupos experimental e controle com RR= 4,87 (IC95%=2,93-8,34); NNT= 1,96 (IC95%=1,61-2,72); p<0,001.No grupo experimental percebeu-se que houve diminuição dos parâmetros desfavoráveis da técnica de amamentar (p≤0,05). A incidência de trauma mamilar foi de 30% no grupo experimental e 38,9% no grupo controle (p=0,21). Conclusão: no grupo experimental a intervenção realizada não foi suficiente para prevenir a ocorrência de traumas mamilares, porém melhorou significantemente a qualidade da técnica de amamentar.

Effect of an educational intervention on the breastfeeding technique on the prevalence of exclusive breastfeeding / Efeito de uma intervenção educativa sobre a técnica de amamentação na prevalência do aleitamento materno exclusivo

Abstract Objectives: to evaluate the effect of an intervention directed to the breastfeeding technique in the prevalence of exclusive breastfeeding in the first month of life. Methods: this is a quasi-randomized intervention study conducted in a public maternity ward accredited in the Baby-Friendly Hospital Initiative. The intervention consisted of individual orientations on the breastfeeding technique in the first 48 hours after delivery, with the help of a breast model, doll, and movie. The control group was oriented by researchers about the importance of breastfeeding, and received hospital orientations. Data were collected in the maternity ward, and at the end of the first month in the hospital's outpatient service by implementing a questionnaire, observing the baby's breastfeeding technique and examining breasts. Results: the prevalence of exclusive breastfeeding in the first month of life of the infant was 76.6% in the experimental group, and 52.2% in the control group. RR=1.46 (CI95%=1.16-1.84); NNT=4.09; p=0.001. The trained women presented a correct breast-feeding technique in 64.04%, much higher when compared to those who did not receive training (15.11%;RR=4.87[CI95%=2.93-8.34]; NNT=1.96;p<0.001). Conclusions: the use of audiovisual resources, use of instruments (model breast and doll), and type of individualized approach contributed to an increased prevalence of exclusive breastfeeding up to 30 days after delivery.

Resumo Objetivos: avaliar o efeito de uma intervenção direcionada à técnica de amamentação na prevalência de aleitamento materno exclusivo no primeiro mês de vida. Métodos: foi realizado um estudo de intervenção quasi randomizado em uma maternidade pública, credenciada como Amigo da Criança. A intervenção consistiu em orientações individuais sobre a técnica de amamentação nas primeiras 48 horas após o parto, com ajuda de seio cobaia, boneca e filme. O grupo controle foi orientado sobre a importância do aleitamento materno pelas pesquisadoras, além das orientações fornecidas pelo hospital. A coleta de dados ocorreu na maternidade e ao final do primeiro mês em serviço ambulatorial do hospital, mediante a aplicação de um questionário, observação da mamada e exame das mamas. Resultados: a prevalência do aleitamento materno exclusivo, no primeiro mês de vida do lactente, foi de 76,6% no grupo experimental e 52,2% no grupo controle. RR=1,46 (IC95%=1,16-1,84); NNT=4,09; p=0,001. As mulheres que sofreram a intervenção, apresentaram técnica correta de amamentação em proporção significativamente maior que os controles: 64,04% vs 15,11%, RR= 4,87 [IC95%= 2,93-8,34] NNT= 1,96; p<0,001. Conclusões: a utilização de recursos audiovisuais, uso de instrumentos (seio cobaia e boneca) e tipo de abordagem individualizada contribuíram para o aumento da prevalência do aleitamento materno exclusivo até 30 dias pós parto.

Prevalência de Sintomas Depressivos em Estudantes de Medicina com Currículo de Aprendizagem Baseada em Problemas / Prevalence of Depressive Symptoms in Medical Students Following a Problem-Based Learning Curriculum

Resumo: Introdução: A depressão é um distúrbio heterogêneo, com etiologia, evolução e resposta terapêutica variadas, com relatos de aumento crescente na incidência entre os jovens. Dois objetivos nortearam este estudo: estimar a prevalência de sintomas depressivos entre acadêmicos de Medicina de uma universidade com métodos ativos de aprendizagem e investigar possíveis associações com variáveis sociodemográficas. Métodos: Trata-se de um estudo transversal descritivo. Aplicaram-se um questionário eletrônico com variáveis sociodemográficas e o Inventário de Depressão de Beck (BDI). Foram realizadas análise univariada e regressão logística multivariada. Resultados: Avaliamos 173 discentes, com discreta predominância de rapazes (n = 93, 53,7%) e idade mediana de 24 (22-26) anos. Verificaram-se sintomas depressivos em 46,2% (n = 80), dos quais 33,5% (n = 58) leves, 9,2% (n = 16) moderados e 3,4% (n = 6) graves. Sexo feminino (p = 0,032) e insatisfação com a Aprendizagem Baseada em Problemas - ABP (p < 0,001) se associaram de forma independente aos sintomas depressivos em regressão logística multivariada, com aumento na chance de sintomas depressivos de 2 e 3,5 vezes, respectivamente. Os fatores morar com os pais, ter outros diagnósticos psiquiátricos e praticar regularmente atividade física se associaram aos sintomas depressivos apenas em análise univariada. Conclusão: Os acadêmicos de Medicina apresentaram significativa prevalência de sintomas depressivos. A associação dos sintomas depressivos com insatisfação com o método ABP pode fomentar reflexões sobre a conduta pedagógica e as deficiências na aplicação da metodologia ABP na referida universidade. Ressaltamos a importância da implementação da atividade física no projeto pedagógico e curricular do curso de Medicina como estratégia para a promoção de saúde mental e física nos discentes.

Abstract: Introduction: Depression is a heterogenous disorder of diverse etiology, progression and therapeutic response. Increasing incidence of depression in young adulthood has been reported. The purpose of this paper was to evaluate the prevalence of depressive symptoms among medical students at a university which adopts an active learning method and to investigate possible associations to sociodemographic variables. Methods: Descriptive, cross-sectional study. An electronic questionnaire was applied to evaluate sociodemographic variables and depressive symptoms using the Beck Depression Inventory. Univariate and multivariate logistic regression analysis were performed. Results: A slight male predominance (n=93, 53.7%) was found among 173 students, along with an average median age of 24 [22-26]. Depressive symptoms were identified in 46.2% of the students (n=80): 33.5% (n=58) with mild symptoms, 9.2% (n=16) moderate, and 3.4% (n=6) severe. Female gender (p=0.032) and dissatisfaction with the active learning method (p<0.001) were independently associated with depressive symptoms in a multivariate logistic regression analysis with the chance of suffering from depressive symptoms increasing 2 and 3.5 fold, respectively. Living with one's parents, additional psychiatric diagnosis, and lack of regular physical exercise were associated with depressive symptoms only in univariate analysis. Conclusion: The medical students presented a high prevalence rate of depressive symptons. Association between dissatisfaction with the active learning method and depressive symptoms may offer some insight regarding the pedagogical practices and deficiencies in the application of this method at the university in question. It is important to implement strategies that incorporate physical exercise into the pedagogical and curricular project to promote the mental and physical health of the students.

Prevalence of priapism in individuals with sickle cell disease and implications on male sexual function / Prevalência de priapismo em indivíduos com doença falciforme e suas implicações na função sexual masculina

ABSTRACT Objective To evaluate epidemiological aspects of priapism in patients with sickle cell disease, and these aspects impact on adult sexual function. Methods This was a cross-sectional study including individuals with sickle cell disease who were evaluated at a reference center for sickle cell. Participants completed a structured questionnaire about their sociodemographic characteristics and priapism events. Sexual function was assessed using validated two instruments, the Erection Hardness Score and one about the sex life satisfaction. Results Sixty-four individuals with median aged of 12 (7 to 28) years were interviewed. The prevalence of priapism was 35.9% (23/64). The earliest priapism episode occurred at 2 years of age and the latest at 42 years. The statistical projection was that 71.1% of individuals of the study would have at least one episode of priapism throughout life. Patients with episodes of priapism (10/23) had significantly worse erectile function Erection Hardness Score of 2 [1-3]; p=0.01 and were less satisfied with sexual life 3 [3-5]; p=0.02. Conclusion Priapism is usually present in childhood, and severe episodes are associated with cavernous damage, impairment in the quality of the erection, and lower sexual satisfaction.

RESUMO Objetivo Avaliar aspectos epidemiológicos do priapismo em pacientes com doença falciforme e o impacto desses aspectos na função sexual de adultos. Métodos Trata-se de estudo transversal, que incluiu indivíduos com doença falciforme acompanhados em um centro de referência. Os participantes responderam a um questionário estruturado acerca das características sociodemográficas e eventos de priapismo. A função sexual foi avaliada por meio de dois instrumentos validados, a Escala de Rigidez de Ereção e um sobre satisfação com a vida sexual. Resultados Foram entrevistados 64 indivíduos com média de idade de 12 (7-28) anos. A prevalência de priapismo foi de 35,9% (23/64). O episódio mais precoce ocorreu aos 2 anos de idade e o mais tardio, aos 42 anos. A projeção estatística foi de que 71,1% desses sujeitos teriam pelo menos um episódio de priapismo ao longo da vida. Pacientes adultos com episódios de priapismo (10/23) apresentaram função erétil significativamente pior Escala de Rigidez de Ereção de 2 [1-3]; p=0,01 e estavam menos satisfeitos com a vida sexual 3 [3-5]; p=0,02. Conclusão O priapismo manifesta-se desde a infância, e episódios graves estão associados a dano cavernoso, prejuízo na qualidade da ereção e menor satisfação sexual.

Prevalence of enuresis and its impact in quality of life of patients with sickle cell disease

ABSTRACT Introduction Evidence indicates an increase in the prevalence of enuresis in individuals with sickle cell disease. The present study aims to evaluate the prevalence and impact of enuresis on quality of life in individuals with sickle cell disease. Materials and Methods This cross-sectional study evaluated individuals with sickle cell disease followed at a reference clinic, using a questionnaire designed to evaluate the age of complete toilet training, the presence of enuresis and lower urinary tract, and the impact on quality of life of these individuals. Results Fifty children presenting SCD (52% females, mean age ten years) were included in the study. Of those, 34% (17/50) presented as HbSC, 56% with HbSS (28/50), 2% Sα-thalassemia (1/5) and 8% the type of SCD was not determined. The prevalence of enuresis was 42% (21/50), affecting 75% of subjects at five years and about 15% of adolescents at 15 years of age. Enuresis was classified as monosymptomatic in 33.3% (7/21) and nonmonosymptomatic in 66.6% (14/21) of the cases, being primary in all subjects. Nocturia was identified in 24% (12/50), urgency in 20% (10/50) and daytime incontinence 10% (5/50) of the individuals. Enuresis had a significant impact on the quality of life of 67% of the individuals. Conclusion Enuresis was highly prevalent among children with SCD, and continues to be prevalent throughout early adulthood, being more common in males. Primary nonmonosymptomatic enuresis was the most common type, and 2/3 of the study population had a low quality of life.

Cross-cultural adaptation and validation of the neurogenic bladder symptom score questionnaire for brazilian portuguese

ABSTRACT Objective: To cross-culturally adapt and check for the reliability and validity of the neurogenic bladder symptom score questionnaire to Brazilian Portuguese, in patients with spinal cord injury and multiple sclerosis. Materials and Methods: The questionnaire was culturally adapted according to international guidelines. The Brazilian version was applied in patients diagnosed with neurogenic bladder due to spinal cord injury or multiple sclerosis, twice in a range of 7 to 14 days. Psychometric properties were tested such as content validity, construct validity, internal consistency, and test-retest reliability. Results: Sixty-eight patients participated in the study. Good internal consistency of the Portuguese version was observed, with Cronbach α of 0.81. The test-retest reliability was also high, with an Intraclass Correlation Coefficient of 0.86 [0.76 - 0.92] (p<0.0001). In the construct validity, the Pearson Correlation revealed a moderate correlation between the Portuguese version of the NBSS and the Qualiveen-SF questionnaire (r = 0.66 [0.40-0.82]; p <0.0001). Conclusions: The process of cross-cultural adaptation and validation of the NBSS questionnaire for the Brazilian Portuguese in patients with neurogenic lower urinary tract dysfunction was concluded.

Prolonged toilet training in children with Down syndrome: a case-control study / Treinamento esfincteriano em crianças com síndrome de Down: estudo caso-controle

Abstract Objectives Children with Down syndrome have delayed psychomotor development, which is a factor that influences the level of difficulty in toilet training. The current study aims to estimate the age toilet training starts and completes in children with DS compared to children with normal psychomotor development and to evaluate the method and type of toilet training most frequently used, as well as its association with lower urinary tract symptoms and functional constipation. Methods A case-control study was carried out from 2010 to 2015. All parents completed a questionnaire designed to assess the toilet training process. Lower urinary tract symptoms were assessed through the application of the Dysfunctional Voiding Symptom Score. The presence of functional constipation was assessed according to the Rome III criteria. Results The study included 93 children with Down syndrome and 204 children with normal psychomotor development (control group [CG]). The mean age of toilet training onset was 22.8 months in those with DS and 17.5 months in the CG (p = 0.001). In children with DS, the mean age when completing toilet training was 56.2 months and 27.1 months in the CG (p = 0.001). Among children with DS, females completed toilet training earlier (p = 0.02). The toilet training method used most often was child-oriented approach in both groups. No association was observed with the presence of lower urinary tract symptoms or functional constipation and the age of beginning and completing toilet training in both groups. Conclusion Children with Down syndrome experienced prolonged toilet training time. Prospective longitudinal studies are essential to gain insight into the toilet training of these children.

O presente estudo tem como objetivo estimar a idade em que o treinamento esfincteriano é iniciado e concluído em crianças com SD em comparação com crianças com desenvolvimento psicomotor normal, avaliar o método e o tipo de treinamento esfincteriano utilizado com maior frequência, bem como sua associação com sintomas do trato urinário inferior e constipação funcional. Métodos Um estudo caso-controle foi realizado de 2010 a 2015. Todos os pais preencheram um questionário destinado a avaliar o processo de treinamento esfincteriano. O sintomas do trato urinário inferior foram avaliados por meio da aplicação do Dysfunctional Voiding Symptom Score. A presença de constipação funcional foi avaliada de acordo com os critérios Roma III. Resultados O estudo incluiu 93 crianças com síndrome de Down e 204 crianças com desenvolvimento psicomotor normal (Grupo de Controle [GC]). A idade média em que as crianças iniciaram o treinamento esfincteriano foi de 22,8 meses naquelas com SD e 17,5 meses no GC (p = 0,001). Em crianças com SD, a idade média ao concluir o treinamento esfincteriano foi de 56,2 meses e 27,1 meses no GC (p = 0,001). Entre as crianças com SD, as do sexo feminino concluíram o treinamento esfincteriano mais cedo (p = 0,02). O método de treinamento esfincteriano mais utilizado foi a abordagem voltada para a criança em ambos os grupos. Não houve associação com a presença de sintomas do trato urinário inferior ou constipação funcional e a idade no início e na conclusão do treinamento esfincteriano em ambos os grupos. Conclusão Crianças com síndrome de Down apresentaram tempo de treinamento esfincteriano prolongado. Estudos longitudinais prospectivos são essenciais para obter uma visão do treinamento esfincteriano dessas crianças.

Smoking and its association with cryptorchidism in Down syndrome / Associação entre tabagismo e criptorquidia na síndrome de Down

Summary Introduction: Cryptorchidism is a common and prevalent condition in patients with Down syndrome. Environmental factors, such as smoking, can be associated with malformations during fetal development. The study of the prevalence of cryptorchidism and its association with parental tobacco use in Down syndrome can contribute to alert health care professionals, patients and family members regarding the prevention of the harms caused by cryptorchidism and its possible predisposing factors. Objective: To evaluate the prevalence of cryptorchidism in Down syndrome and its association with maternal and paternal smoking. Method: Forty (40) patients of a public clinic specialized in Down syndrome were evaluated, using a semi-structured questionnaire for evaluation of antecedents and sociodemographic characteristics, as well as physical and complementary examinations. Results: Cryptorchidism was observed in 27.5% of the patients (95CI 15.98-42.96). Of these, 55% (5/9) were the children of mothers who smoked during pregnancy, and 19.35% (6/31) were the children of mothers who did not smoke during pregnancy (OR = 5.26 [95CI 1.06-25.41]; p=0.032). Similarly, paternal smoking was also observed in greater frequency among the parents of cryptorchid patients compared with subjects with descended testis, 63.36% (7/11) and 31.03% (9/29), respectively (OR = 3.89 [95CI 0.91-16.73]; p=0.060). Conclusion: The prevalence of cryptorchidism is high in patients with Down syndrome. We can show a strong association between smoking parents and the occurrence of cryptorchidism, especially when it comes to maternal smoking.

Resumo Introdução: A criptorquidia é uma condição comum e prevalente em pacientes com síndrome de Down. Fatores ambientais, como o tabagismo, estão associados a malformações fetais. A avaliação da prevalência do criptorquidismo e a associação com tabagismo dos pais na síndrome de Down podem contribuir para alertar os profissionais de saúde e familiares sobre a prevenção dos danos causados pelo criptorquidismo e os possíveis fatores predisponentes. Objetivo: Avaliar a prevalência de criptorquidismo na síndrome de Down e a associação com tabagismo materno e paterno. Método: Quarenta (40) pacientes acompanhados em um centro de referência para atendimento da síndrome de Down foram avaliados por meio de questionário semiestruturado para avaliação de antecedentes parentais e características sociodemográficas, bem como de exames físico e laboratoriais complementares. Resultados: Criptorquidia foi observada em 27,5% dos pacientes (IC95% 15,98-42,96). Nesses pacientes, o criptorquidismo foi encontrado em 55% (5/9) das crianças cujas mães fumavam e em 19,35% (6/31) daquelas cujas mães não fumavam (OR = 5,26 [IC95% 1,06-25,41]; p=0,032). Do mesmo modo, o tabagismo paterno foi observado com maior frequência entre crianças com criptorquidia, 63,36% (7/11) e 31,03% (9/29), respectivamente (OR = 3,89 [IC95% 0,91-16,73]; p=0,060). Conclusão: A prevalência de criptorquidismo é alta em pacientes com síndrome de Down. Podemos mostrar uma forte associação entre hábito tabágico dos pais e ocorrência de criptorquidismo, especialmente no caso de tabagismo materno.

Association between renal cysts and abdominal aortic aneurysm: A case-control study / Associação entre cistos renais e aneurismas da aorta abdominal: Um estudo de caso-controle

Summary Objective: To investigate the positive association between the presence of simple renal cysts (SRCs) and abdominal aortic aneurysm (AAA). Method: In a retrospective case-control study including subjects aged > 50 years, we evaluated the incidence of SRCs on computed tomography (CT) scan. We compared 91 consecutive patients with AAA referred from the Division of Vascular Surgery and 396 patients without AAA, randomly selected after being matched by age and gender from 3,186 consecutive patients who underwent abdominal CT. SRC was defined as a round or oval low-attenuation lesion with a thin wall and size > 4 mm on CT without obvious evidence of radiographic enhancement or septations. Patients were considered as having AAA if the size of aorta was greater than 3.0 cm. Results: Patients with AAA and without AAA were similar in terms of age (67.9± 8.41 vs. 68.5±9.13 years) (p=0.889) and gender (71.4 vs. 71.2% of male subjects, respectively) (p=0.999). There was no difference in the prevalence of SRC between case and controls. Among individuals with AAA, 38 (41.8%; [95CI 32.5-52.6]) had renal cysts compared to 148 (37.4%; [95CI 32.7-42.2]) in the control group (p=0.473), with a prevalence ratio (PR) of 1.16 (95CI 0.80-1.68). Conclusion: We found no significant differences in the prevalence of SRCs among patients with AAA and controls. Our findings suggest that the presence of SRCs is not a risk factor or a marker for AAA.

Resumo Objetivo: Avaliar uma possível associação entre presença de cistos renais simples (CRS) e aneurisma aórtico abdominal (AAA). Método: Em um estudo de caso versus controle com sujeitos com idade > 50 anos, avaliamos a prevalência de CRS detectados por tomografia computadorizada (TC). Comparamos os achados de 91 pacientes consecutivos com AAA oriundos da Divisão de Cirurgia Vascular com 396 pacientes sem AAA, randomicamente selecionados e ajustados por idade e gênero dentre 3.186 pacientes consecutivos que se submeteram a TC abdominal. Cisto simples foi definido como lesão hipodensa oval ou arredondada com paredes finas, maiores do que 4 mm em TC sem realce contrastual ou septação. Pacientes foram considerados com AAA quando o diâmetro da aorta era maior que 3,0 cm. Resultados: Pacientes com AAA e sem AAA eram semelhantes quanto a idade (67,9±8,41 vs. 68,5±9,13 anos) (p=0,889) e gênero (71,4 vs. 71,2% dos indivíduos masculinos, respectivamente) (p=0,999). Não havia diferença de prevalência de CRS entre casos e controles. Dentre indivíduos com AAA, 38 (41,8%; [IC95% 32,5-52,6]) tinham cistos renais, comparados com 148 (37,4%; [IC95% 32,7-42,2]) no grupo controle (p=0,473), com uma razão de prevalência (RP) de 1,16 (IC95% 0,80-1,68). Conclusão: Não observamos diferenças significativas na prevalência de CRS entre pacientes com AAA e controles. Nossos resultados sugerem que presença de CRS não é fator de risco ou preditor para AAA.

Neurological status predicts response to alpha-blockers in men with voiding dysfunction and Parkinson's disease

OBJECTIVES: To evaluate predictors of the response to doxazosin, a selective alpha-adrenoceptor antagonist, when used for the treatment of lower urinary tract symptoms in men with Parkinson's disease. METHODS: In a prospective study, 33 consecutive men (mean age 59.2±7.0 years) with Parkinson's disease and lower urinary tract symptoms were evaluated. Neurological dysfunction was assessed with the Unified Parkinson's Disease Rating Scale. Urological assessment was performed at baseline and after 12 weeks of treatment with 4 mg/day of extended-release doxazosin, including symptom evaluation with the International Continence Society male short-form questionnaire, an assessment of the impact of lower urinary tract symptoms on quality of life and urodynamics. Clinical and urodynamic predictors of response were specifically evaluated. RESULTS: Compared with the score at baseline, the total International Continence Society male short-form score was reduced after doxazosin administration, from 17.4±7.5 to 11.1±6.9 (p<0.001). The impact of lower urinary tract symptoms on quality of life was also significantly reduced, from 1.8±1.1 to 1.0±1.0 (p<0.001) and the maximum urinary flow varied from 9.3±4.4 to 11.2±4.6 ml/s (p = 0.025). The severity of neurological impairment ...

Índice de volume do átrio esquerdo é um preditor independente de morte por causa cardiovascular no primeiro ano de tratamento com hemodiálise / Left atrial volume index is an independent predictor of cardiovascular mortality in the first year of hemodialysis

Introdução: O índice de volume do átrio esquerdo (IVAE) é um preditor independente para eventos cardiovasculares (CV), em pacientes que fazem hemodiálise (HD), há mais de 01 ano. Entretanto, a mortalidade desses pacientes é maior no primeiro ano de tratamento com HD. Objetivo: Avaliar o valor prognóstico do IVAE, como preditor de morte por causa CV, nos pacientes com IRC, dentro do primeiro ano de tratamento com HD. Métodos: Estudo prospectivo e observacional, incluindo pacientes com IRC e indicação imediata para iniciar tratamento do HD. Os participantes foram acompanhados durante 01 ano: 03 sessões de hemodiálise por semana, com 04 horas/sessão. Todos realizaram um ecocardiograma, até 24 horas após a primeira sessão de hemodiálise. Resultados: Foram incluídos 50 pacientes com média de 55 anos (18-94), sendo 30 (60%) homens. Houve 09 (18%) mortes por causa CV. O IVAE, antes de começar HD, era 38,2 +- 10,2ml/m2, sendo 47,7 +- 6,2ml/m2 nos pacientes que morreram por causa CV e 36,2 +- 9,8ml/m2, naqueles sem o desfecho preconizado (p valor=0,002). A curva ROC mostrou IVAE=37,5ml/m2, como o melhor ponto de corte para predição de morte CV (área abaixo da curva=0,85). Não houve morte por causa CV entre os 26 participantes que apresentavam IVAE<37,5ml/m2 antes de iniciar HD. Dos 24 pacientes com IVAE...
