One-day voiding diary in the evaluation of Lower Urinary Tract Symptoms in children

ABSTRACT Introduction: Voiding diary (VD) is an important tool in the evaluation of children with voiding symptoms. Voiding frequency, maximal voided volume (MVV), average voided volume (AVV) and nocturnal volume (NV) can be extracted and are valuable in diagnosing and monitoring these disorders. Recently, ICCS has reduced the period of data recording on VD from 3 to 2 days. We hypothesized that one day voiding diary would be enough for guiding treatment. Materials and Methods: Children with overactive bladder (OAB) and primary monosymptomatic enuresis (PMNE) were oriented to fulfill a 3-day VD. Data obtained from VD were evaluated for the first day (1dVD), the first two days (2dVD), and all 3 days (3dVD) and compared according to the MVV, AVV, frequency, NV and expected bladder capacity (EBC). The Friedman, Student's t test and the Fisher's exact was used. ANOVA was used for multiple comparisons. We also used Pearson correlation test. Results: Ninety-eight children were included, 59 had PMNE and 30 OAB. Frequency, AVV and VN were similar regardless how many days the voiding episodes were recorded. Only MVV was higher by a mean of only 32 mL on 3dVD compared to 1dVD. A 1dVD has a sensitivity of 93,9% and a positive likelihood ratio of 2.2. As for the correlation of MVV and EBC it was observed that in 83% of children, MVV was lower than EBC. MVV corresponds to 67% and 69% of EBC in children with PMNE and OAB, respectively. Conclusion: We believe that 1dVD is sufficient to assess these children. It has a high sensitivity and good correlation to 3dVD in evaluating these children. Bladder capacity in this population, evaluated by maximum voided volume, was close to 68% of that obtained by the EBC.

Enuresis and upper airway obstruction: BNP and ADH hormones behavior before and after airway surgery

ABSTRACT Introduction: Upper airway obstruction (UAO) is a common condition in all pediatric population, with a 27% prevalence. Primary monosymptomatic nocturnal enuresis (PMNE) is a condition related to UAO in 8% to 47% of these children. The specific pathophysiological mechanism of this bond is not well understood. Some authors suggest a connection between brain natrituretic peptide (BNP) and anti-diuretic hormone (ADH) during sleep. The aim of this study was to evaluate hormone profile (ADH and BNP) and improvement in dry nights in a sample of children before and after surgical treatment of the UAO. Methods: This is a longitudinal prospective interventionist study in children, 5 to 14 years of age, with UAO and PMNE recruited in a specialty outpatient clinic. Children presenting UAO and PMNE were evaluated with a 30-day dry night diary and blood samples were collected to evaluate ADH and BNP before and after upper airway surgery. Data were analyzed prior to surgery and 90-120 days after surgery. Results: Twenty-one children with a mean age of 9.7 years were included. Mean BNP before surgery was 116.5 ± 126.5 pg/mL and 156.2 ± 112.3 pg/mL after surgery (p<0.01). Mean ADH was 5.8 ± 3.2 pg/mL and 14.6 ± 35.4 before and after surgery, respectively (p=0.26). The percentage of dry nights went from 32.3 ± 24.7 before surgery to 75.4 ± 33.4 after surgery (p<0.01). Conclusion: Surgery for airway obstruction contributed to an increase in BNP without increasing ADH. A total of 85.8% of the children presented partial or complete improvement of their enuresis.

Quality of life in enuretic children

ABSTRACT Introduction: Nocturnal enuresis is a highly incident chronic disorder that generates countless problems to the child and their parents. Bed-wetting has significant negative impacts on self-esteem and the performance of children. The aim of the current study is to assess the quality of life of enuretic children, as well as its association to sex and age. Patients and Methods: Thirty-nine enuretic children (23 boys) and 49 healthy children (27 boys) without any history of previous treatment for enuresis or voiding dysfunction were included. Age ranged between 6 and 11 years old. The "AUQEI" questionnaire was applied in a private environment to all children by the same researcher (psychologist) to evaluate quality of life. Results: Enuretic children displayed loss in quality of life when compared to non-enuretic (35.9% of enuretic x 16.3% of non-enuretic, p=0.035). They were mostly affected in their daily activities (p=0.02). No significant differences were found in the association of sex and gender with quality of life. These results suggest that, children with nocturnal enuresis have 2.87 times more chances of having loss in quality of life compared to non-enuretic. Conclusions: Enuresis has a great impact in quality of life of children. This impact is not related to the age or sex of the child.

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.

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.

Point of care kidney ultrasonography and its role in the diagnosis of urinary obstruction: a case report / Ultrassonografia urinária "Point of Care" e o seu papel no diagnóstico da obstrução urinária: um relato de caso

Abstract Introduction: Ultrasonography (US) is a rapid, non-invasive and safe procedure that allows the nephrologist to obtain vital information to the bedside, as well as allows to guide the procedures for nephrology practice. Case report: Male patient, elderly with hypertension, diabetes mellitus and chronic kidney disease presents with infraumbilical protrusion that the Point of Care US (POCUS), performed by the nephrologist, proved to be a large bladder with a diverticulum. In addition, the US enabled the nephrologist to diagnose bilateral hydronephrosis, preservation of the cortico-medullary differentiation and echotexture of the right kidney, post-voiding urinary retention, urinary catheter placement and functional and morphological monitoring of the urinary tract after surgical correction of the infravesical obstruction. Conclusion: POCUS assessment of the renal tract may become the new standard of care among nephrologists by enabling the expansion of clinical information in a timely fashion, allowing faster resolution of cases and permitting the monitoring of the treatment done.

Resumo Introdução: A ultrassonografia (US) é um procedimento rápido, não invasivo e seguro que possibilita ao nefrologista obter informação vital à beira do leito, assim como permite guiar os procedimentos necessários à prática nefrológica. Relato do caso: Paciente masculino, idoso, com hipertensão arterial, diabetes mellitus e doença renal crônica apresenta-se com abaulamento infraumbilical que a Point of Care US (POCUS), realizada pelo nefrologista, mostrou ser um quadro de retenção urinária acompanhado de divertículo vesical. Adicionalmente, a POCUS possibilitou ao nefrologista diagnosticar hidronefrose bilateral, preservação da diferenciação córtico-medular e da ecotextura do rim direito, retenção urinária pós-miccional, correto posicionamento do cateter vesical pós-drenagem e acompanhar funcionalmente e morfologicamente as alterações do trato urinário após a correção da obstrução infravesical. Conclusão: A avaliação do trato urinário na ótica da POCUS eleva a prática nefrológica a um patamar mais alto, ao possibilitar a ampliação de informações clínicas imediatas e à beira do leito, proporcionar maior rapidez na resolução dos casos e permitir o monitoramento do tratamento instituído.

Abdome agudo: ruptura espontânea de bexiga como um importante diagnóstico diferencial / Acute abdomen: spontaneous bladder rupture as an important differential diagnosis

A case of spontaneous perforation of the bladder in a diabetic female patient is reported. It is a rare clinical condition, that should be suspected in patients with a past history of radiotherapy to the pelvis, enterocystoplasty and those suspected of having a tumor in the bladder. A general surgeon should be aware of this possibility in the differential diagnosis of an acute abdomen.

Ampliação vesical para o tratamento de bexiga contraída por tuberculose: análise dos resultados e comparação entre as diferentes técnicas / Bladder augmentation for treatment of chronic tuberculous cystitis: analysis of the results and comparison among techniques

Foi realizada a avaliação clínica, radiológica e urodinâmica do seguimento tardio de 25 pacientes com bexiga contraída por tuberculose submetidos à ampliação vesical. Em oito casos, a ampliação foi feita com segmento ileocecal não destubulizado, em quatro com sigmóide não destubulizado e em 13 com sigmóide destubulizado. O seguimento pós-operatório médio foi de 11.1 ± 9.1 anos (1 a 36). A ampliação vesical permitiu a resolução da polaciúria e satisfação do paciente em 80 por cento dos casos. O mau resultado ocorreu na ampliação com sigmóide não destubulizado e nos pacientes com prostatite por tuberculose / Clinical, radiological and urodynamic evaluation of the late outcome of 25 patients with chronic tuberculous cystitis who underwent bladder augmentation was done. In eight cases the augmentation was made with tubularisated ileocecal segment, in four with tubularisated sigmoid and in 13 with detubularisated sigmoid. The average postoperative follow up was of 11.1 ± 9.1 years (1 to 36). The bladder augmentation solved the increased daytime frequency in 80 per cent of the patients after a long term follow-up. A poor outcome occurred in the cases using tubularized sigmoid and in the patients with prostatitis. Miccional daytime frequency of at least two hours occurred in augmented bladder with higher capacity and compliance and with normal sensation without interference of the presence of involuntary contractions...

Bilateral giant renal angiomyolipoma associated with hepatic lipoma in a patient with tuberous sclerosis

OBJECTIVE: To report a case of bilateral giant renal angiomyolipoma associated with tuberous sclerosis, with successful treatment, and to review the literature concerning angiomyolipoma treatment. CASE REPORT: Patient with tuberous sclerosis and angiomyolipoma diagnosed by ultrasonography during her pregnancy. At that time, the angiomyolipoma on the right side was 9 cm in diameter. Conservative management was selected during her pregnancy. The patient returned 7 years later, with a 24.7 x 19.2 x 10.7 cm tumor on the right side and another of 13 x 11.5 x 6.5 cm on the left side, in addition to multiple small angiomyolipomas. A nephron-sparing surgery with tumoral enucleation was performed on the right side, and after 3 months, the tumor on the left side was removed. Renal function in the post-operative period was preserved, and contrast medium progression was uniform and adequate in both kidneys. CONCLUSION: We conclude that an angiomyolipoma larger than 4 cm should be removed surgically, since they have a greater growth rate and pose a risk of hemorrhage. Resection of smaller tumors is safe and has decreased morbidity. Tumoral enucleation is an effective treatment method that preserves kidney function

Emprego de grampeadores para anastomose intestinal em cirurgia colorretal / Employment of intestinal staplers in colorrectal surgery

Grampeadores sao instrumentos utilizados na pratica cirurgica, onde grampos colocados em cartuchos sao forcados mecanicamente a assumir a conformacao em B, unindo duas estruturas. Depois de experimentos na Europa Oriental, houve um grande desenvolvimento na Russia, onde nasceram os principais grampeadores que ate hoje utilizamos. Coube aos americanos a divulgacao e padronizacao das tecnicas. O uso dos grampeadores deve obedecer as mesmas premissas empregadas nas suturas manuais. A anastomose deve ser confeccionada com tecnica adequada, sem tensao e tecidos desvitalizados e com boa irrigacao das bordas a serem anastomosadas. Diversos procedimentos cirurgicos em coloproctologia sao descritos com a utilizacao dos grampeadores, sendo que as resseccoes anteriores do reto e as anastomoses ileo-retais com reservatorio ileal sao para nos as indicacoes mais apropriadas. Os diversos estudos realizados mostram que nao ha diferenca entre os indices de complicacao das suturas mecanicas e os das suturas manuais...
