Riñón pélvico fusionado con uréter único, hidrometrocolpos y ano imperforado: conjunción de malformaciones infrecuentes en una adolescente / Pancake kidney with a single ureter, hydrometrocolpos, and imperforate anus: a set of uncommon malformations in a female adolescent

Una niña de 11 años de edad con antecedentes de ano imperforado, infección urinaria y episodios de constipación intermitentes se presentó a la consulta con cólicos abdominales y náuseas de una semana de evolución. Estudios radiológicos revelaron hidrometrocolpos y fusión renal pélvica con uréter único hidronefrótico. El examen vaginal evidenció un tabique transverso no permeable. Se evacuó temporalmente la colección con resolución de los síntomas. La paciente fue programada para cirugía vaginal reconstructiva definitiva. Se destaca en este caso no solo la asociación de malformaciones infrecuentes, sino una sintomatología muy común en la práctica pediátrica a causa de una patología rara vez considerada en el diagnóstico diferencial, y la importancia de una evaluación precoz y completa de este tipo de malformaciones para un tratamiento oportuno.

An 11-year-old girl with a history of imperforate anus, urinary tract infection, and intermittent episodes of constipation presented with abdominal pain and nausea for 1 week. The x-rays revealed hydrometrocolpos and fused pelvic kidney with a single hydronephrotic ureter. The vaginal examination revealed a non-permeable transverse vaginal septum. The collection was temporarily drained and symptoms resolved. The patient was scheduled for definitive vaginal reconstructive surgery. In this case, it is worth noting the association of infrequent malformations and also the signs and symptoms very common in pediatric practice due to a pathology rarely considered in the differential diagnosis, and the importance of an early and complete assessment of this type of malformations for a timely treatment.

Association between Genitourinary and Congenital Heart Defects: A 52-year Case-Control Study of the Latin American Collaborative Study of Congenital Malformations (ECLAMC) / Asociación entre cardiopatías congénitas y malformaciones congénitas urinarias: Un estudio de casos y controles de 52 años del Estudio Colaborativo Latino Americano de Malformaciones Congénit

Background Congenital urological anomalies are present in 4.3/10 thousand newborns, and their association with other anomalies may increase the overall mortality and disability. The present study establishes the risk of having congenital urological anomalies presenting associated cardiopathies. Methods We conducted a retrospective case-control study using the Latin American Collaborative Study of Congenital Malformations (Estudio Colaborativo Latino Americano de Malformaciones Congénitas, ECLAMC, in Spanish). The analysis included all registered cases of congenital urological malformation from 1967 to 2019. Patients with or without associated heart defects were included for the statistical analysis. Odds ratios (ORs) were calculated using a 95% confidence interval (95% CI). We compared the variables with the Chi-squared test and analysis of variance (ANOVA). The statistical analysis was performed using the Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY, United States) software, version 27.0. Values of p < 0.05 were considered statistically significant. Results A total of 7,767,161 newborns were evaluated, and 17,834 genital and upper urinary tract malformations were identified. Of these, 64.2% were genital anomalies, and 35.8% were abnormalities of the upper urinary tract. Genitourinary malformations and concomitant congenital heart defects (GU + C) were observed in 3.5% of the cases. Subjects with GU + C had a higher number of malformations (4.59 ± 2.3) than patients without heart defects (1.53 ± 1.58) (p < 0.000). The OR was of 3.61 (range: 1.86­7.00) for cloacal exstrophy, of 4.01 (range: 3.14­5.12) for imperforate anus, of 5.52 (range: 3.92­7.78) for horseshoe kidney, and of 13.7 (range: 6.65­28.22) for trisomy 21 (Down syndrome) with malformations of the upper urinary tract. Conclusion The association of congenital heart defects with urological anomalies is higher for complex congenital anomalies such as imperforate anus, cloacal exstrophy, and ho

Introducción Las malformaciones congénitas urológicas están presentes en 4,3/10 mil, y su asociación con otros defectos puede aumentar la mortalidad global y la discapacidad. Este estudio analiza la presentación de las malformaciones congénitas urológicas asociadas a las cardiopatías congénitas. Métodos Este es un estudio retrospectivo de casos y controles que usa el Estudio Colaborativo Latinoamericano de Malformaciones Congénitas (ECLAMC). Se incluyeron todos los casos registrados de malformaciones congénitas urológicas de 1967 a 2019, y todos los casos con y sin defectos cardiacos. Se calculó la razón de disparidad (RD) usando un intervalo de confianza del 95% (IC 95%). Se probó la hipótesis con el Chi-cuadrado y análisis de la varianza (analysis of variance, ANOVA, en inglés). Se realizó el análisis estadístico por medio del programa Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Armonk, NY, Estados Unidos), versión 27.0. Se consideró la significancia estadística con valores de p < 0,05. Resultados Se evaluaron 7.767.161 recién nacidos, y se identificaron 17.834 malformaciones genitales y del tracto urinario superior. De estas, 64,2% fueron genitales, y 35,8%, de vías urinarias superiores. El 3,5% de los casos tenían malformaciones genitourinarias y defectos cardiacos congénitos concomitantes (GU + C). Aquellos con GU + C tenían mayor número de malformaciones (4,59 ± 2,3) que los pacientes sin defectos cardiacos (1,53 ± 1,58) (p < 0,000). La RD fue de 3.61 (rango: 1,86­700) para la extrofia cloacal, de 4,01 (3,14­5,12) para el ano imperforado, de 5,52 (3,92­7,78) para el riñón en herradura, y de 13,7 (6,65­28,22) para la trisomía 21 (síndrome de Down) con malformaciones del tracto urinario superior. Conclusión La asociación entre defectos cardiacos congénitos y anomalías urológicas es significativa en malformaciones congénitas complejas como el ano imperforado, la extrofia cloacal, y el riñón en herradura. Los pacientes con síndrome de Down y malformaciones urológicas tienen la mayor probabilidad.

Atresia esofágica tipo III associada a ânus imperfurado: um relato de caso / Esophageal atresia type III associated to imperforate anus: a case report

Introdução: As malformações congênitas são defeitos que ocorrem durante o desenvolvimento embrio-fetal, principalmente entre a terceira e oitava semana de gestação, podendo ser suspeitado no período pré-natal. A atresia de esôfago com ou sem fístula traqueoesofágica pode estar associada a outras anomalias congênitas, como o ânus imperfurado, o qual faz parte uma síndrome denominada malformação anorretal. Objetivo: discutir o caso de um recém-nascido (RN) portador de atresia de esôfago tipo III e ânus imperfurado, bem como associar suas ocorrências simultâneas. Relato de caso: paciente do sexo masculino, advindo de uma gestação gemelar complicada por pré-eclâmpsia, apresentava ao nascimento ausência do reflexo de busca e sucção, bradicardia e cianose central. Foi diagnosticado com ânus imperfurado e atresia esofágica. Foram realizados cirurgia de Colostomia em Duas Bocas e tratamento cirúrgico da atresia de esôfago. O paciente ficou 48 dias em incubadora com intubação orotraqueal e ventilação mecânica por 26 dias. Resultado: a programação pós- alta indicada foi o acompanhamento com cirurgião pediátrico e neurocirurgião, tendo evoluído bem e aguardando anorretoplastia. Conclusão: o rápido diagnóstico é tão necessário, nesses casos, quanto as abordagens cirúrgicas. O apoio psicológico aos familiares é de extrema importância, pois visa a melhor aceitação da família frente ao caso, propiciando dessa forma, melhores prognóstico e tratamento do paciente.

Introduction: Congenital malformations are defects that occur during embryo-fetal development, especially between the third and eighth week of pregnancy, and may be suspected in the prenatal period. Esophageal atresia with or without tracheoesophageal fistula may be associated with other congenital anomalies, such as the imperforate anus, which is part of a syndrome called anorectal malformation. Objective: to discuss the case of a newborn (NB) with type III esophageal atresia and imperforate anus, as well as to associate its simultaneous occurrences. Case report: male patient, resulting from a twin pregnancy complicated by pre-eclampsia, had at birth the absence of the search and suction reflex, bradycardia and central cyanosis. He was diagnosed with imperforate anus and esophageal atresia. Double-barrel colostomy surgery and esophageal atresia surgery were performed. The patient spent 48 days in an incubator with orotracheal intubation and mechanical ventilation for 26 days. Results: the post-discharge schedule indicated was for follow-up with a pediatric surgeon and neurosurgeon. Patient evolved well and awaits anorectomy. Conclusion: rapid diagnosis is as necessary in these cases as surgical approaches. Psychological support to family members is extremely important, as it aims at better family acceptance in the case, thus providing better prognosis and treatment for the patient.

Double-lumen Aortic Arch: Persistence of the Fifth Aortic Arch?

Abstract Double-lumen aortic arch is a rare congenital anomaly related to persistence of the fifth aortic arch. It may be found alone or in association with other anatomical changes of the heart. We report a case of double-lumen aortic arch associated with coarctation of the aorta and patent ductus arteriosus in a child with a congenital malformation known as the VACTERL association (vertebral defects, imperforate anus, cardiopathy, tracheoesophageal fistula, renal abnormalities and limb anomalies).

Asociación VACTERL de presentación inusual: reporte de caso / VACTERL Association with Unusual Presentation: Case Report / Associação VACTERL de apresentação rara: relato de caso

Resumen: En el contexto de Asociación VACTERL, el diagnóstico prenatal de atresia esofágica concomitante con atresia duodenal es poco común. En el presente artículo se realiza el reporte de un caso con la descripción de los hallazgos ecográficos encontrados a partir semana doce de gestación, con la aparición del signo de doble burbuja intraabdominal compatible con atresia duodenal y una arteria umbilical única; y hacia la semana 31 el hallazgo de imagen anecóica y dilatación esofágica del tercio distal con comunicación con la cámara gástrica en corte longitudinal, representando una atresia esofágica, asociada además a polihidramnios. Desde el momento del nacimiento por examen físico y estudios complementarios, se evidenció además ano imperforado con fístula recto vestibular, arcos costales derechos fusionados y hemivértebras. Por los anteriores hallazgos clínicos y radiológicos, se considera que se trata de una asociación VACTERL; sin embargo, sin alteraciones cardiacas, que es una de las características más frecuentemente encontradas. Se realiza una revisión del estado del arte con respecto a la asociación VACTERL y el diagnóstico prenatal de la atresia esofágica y duodenal.

Abstract: In the context of the VACTERL Association, prenatal diagnosis of concomitant esophageal atresia with duodenal atresia is rare. In this article, a case report is described with the description of the ultrasound findings found from week twelve of gestation, with the appearance of the intra-abdominal double bubble sign compatible with duodenal atresia and a single umbilical artery; and towards week 31 the finding of anechoic image and esophageal dilation of the distal-third with communication with the gastric chamber in longitudinal section, representing esophageal atresia, also associated with polyhydramnios. Physical examination and complementary studies from birth showed an imperforate anus with a rectovestibular fistula, and hemivertebrae. Based on the above clinical and radiological findings, it is considered to be a VACTERL association; however, without cardiac abnormalities, which is one of the most frequently found characteristics. A review of the state of the art is carried out with regard to the VACTERL association and the prenatal diagnosis of esophageal and duodenal atresia.

Resumo: No contexto da Associação VACTERL, o diagnóstico pré-natal de atrésia do esôfago concomitante com atrésia de duodeno é pouco comum. Neste artigo, é realizado relato de um caso com a descrição dos achados ecográficos encontrados a partir da 12a semana de gestação, com o surgimento do sinal de dupla bolha intra-abdominal compatível com a atrésia duodenal e uma artéria umbilical única; na 3ia semana, o achado de imagem anecoica e dilatação esofágica do rádio distai com comunicação com a câmara gástrica em corte longitudinal, o que representa atrésia esofágica, associada, ainda, a polidrâmnio. Desde o momento do nascimento por exame físico e estudos complementares, é evidenciado ânus imperfurado com fístula retal vestibular, arcos costais direitos fusionados e hemivértebras. A partir dos achados clínicos e radiológicos, é considerado que se trata de uma associação VACTERL; contudo, sem alterações cardíacas, que é uma das características mais frequentemente encontradas. É realizada uma revisão do estado da arte a respeito da associação VACTERL e o diagnóstico pré-natal da atrésia esofágica e duodenal.

Atresia anal com fístula retovaginal em ovino: relato de caso / Anal Atresia with rectovaginal fistula in sheep: case report

A atresia anal com fístula retovaginal, é considerada uma afecção congênita rara nos ovinos. Em virtude disso, buscou-se descrever o reparo cirúrgico e cuidados pós-operatórios em uma borrega que apresentava essa afecção. Nesse sentido, uma borrega, sem raça definida, de 25 dias de idade e pesando 7,2kg, apresentou sinais de distensão abdominal e defecação pela vulva. A afecção foi diagnosticada por meio do exame clínico e confirmada radiograficamente, constatando-se atresia anal do tipo III em associação com a fístula.(AU)

Atresia ani associated with rectovaginal fistula is considered a rare congenital anomaly in sheep. Therefore, the surgical correction and post-operative care of a lamb presenting atresia ani with rectovaginal fistula has been detailed in this case report. A 25-days old, mixed breed lamb, weighing 7.2 kg, showing signs of abdominal bloating, and stool passage through the vulva was admitted at our hospital. An atresia ani type III condition associated with rectovaginal fistula was diagnosed by clinical examination and confirmed by radiographic examination.(AU)

Congenital multiple arthrogryposis in bovine / Artrogripose congênita múltipla em bovino

This report describes an anal atresia, anatomical urethra alteration (slightly caudal to the udder), thickened joints, and changes in the pelvis in a newborn Holstein cow. Visualization of the final portion of the rectum was not possible by perineal access and laparotomy through the right flank was performed in order for abdominal exploration and colostomy attempt. During the surgical procedure visceral rupture and malformations incompatible with life were observed, so surgeons opted for euthanasia and necropsy. Alterations were confirmed in the genitourinary and gastrointestinal tract. The non-formation of the anus caused dilation of the distal portion of the rectum with fecal content retention, which was drained to the body of the uterus, with the presence of meconium. This amount of anatomical and clinical changes were diagnosed as congenital multiple arthrogryposis.(AU)

Este relato de caso descreve atresia anal, alteração anatômica da uretra (inserida caudalmente ao úbere), articulações espessadas e alterações na pelve em um neonato bovino da raça Holandesa. A visualização da porção final do reto não foi possível pelo acesso perineal, e laparotomia através do flanco direito foi feita para exploração abdominal e realização da colostomia. Durante o procedimento cirúrgico, foram observadas ruptura visceral e malformações incompatíveis com a vida, então os cirurgiões optaram pela eutanásia e necropsia. Alterações foram confirmadas nos tratos geniturinário e gastrointestinal. A não formação do ânus causou dilatação da porção distal do reto com retenção fecal, desviando ao corpo do útero, o qual possibilitou a entrada de mecônio nesse compartimento, além de outras alterações devido à ingestão e alteração no trânsito gastrointestinal. Essa quantidade de alterações anatômicas e clínicas foi diagnosticada como artrogripose congênita múltipla.(AU)

Effect of folic acid in a modified experimental model of anorectal malformations adriamycin-induced in rats

PURPOSE: To determine the effect of a single dose of adriamycin (ADR) to induce anorectal malformations (ARMs) and determine the effect of folic acid (FA) in this model. METHODS: Ten female Wistar rats were divided randomly in two groups. Group A - ADR; Group B - FA+ADR. Dams from group B received daily, since two weeks before the pregnancy to the end of pregnancy, FA (50mg/kg) by gavage. Dams from both groups received ADR (6mk/kg) by intraperitoneal injection on gestational day (GD) 8. Their fetuses were harvested by cesarean section on GD21 and were examined looking for ARMs. The thickness of anal stratified squamous epithelium (ASSE) and intestinal epithelium (IE) were analyzed. p≤0.05*. RESULTS: 81 fetuses were harvested. The number of fetuses; number of ARMs; mean (∆%) (± SD) were determined to be, respectively: ADR - 41[29;65%(±37%)] versus FA+ADR - 40[04;16%(±36%)] (p=0.05). AMRs were significantly lower in FA+ADR group than in ADR group (p=0.05). The thickness (µm) of ASSE (± SD) and IE (± SD) were measured, respectively: ADR - [25.98(±0.74) and 19.48(±1.68)] versus FA+ADR - [24.74(±0.91) and 24.80(±0.81)] (p<0.005). The thickness of IE was significantly enlarged when FA was given (p<0.005). CONCLUSIONS: Single dose of adriamycin on D8 was able to induce anorectal malformations. Folic acid reduces the number and enlarged the IE of ARMs ADR-induced.

Asociación de fistula rectovaginal congénita con ano normal (Fístulas Tipo H) y atresia rectal en una paciente. Reporte de un caso y breve revisión de la literatura / Congenital recto-vaginal fistula associated with a normal anus (type H fistula) and rectal atresia in a patient. Report of a case and a brief revision of the literature.

Las malformaciones ano-rectales del tipo de fístulas recto-urogenitales congénitas con ano normal y atresia rectal son anomalías poco frecuentes. Se discute el caso de una niña con la asociación de estas dos entidades, acompañada además de una vagina doble, quien fue llevada a la consulta a los siete días de vida por la expulsión de heces a través de los genitales. Las malformaciones fueron corregidas a través de un abordaje sagital posterior, con descenso del recto hasta el ano sin disección perineal. El tabique vaginal fue resecado a través de la vulva. En la actualidad no hay evidencia de recurrencia de la fístula recto-vaginal.

Congenital recto-urogenital type fistulas with a normal anus and rectal atresia, represent both anorectal malformations that are infrequently seen in clinical practice. We describe the case of a girl with an association of these two anomalies, together with a double vagina who, on her seventh day of life, expelled feces through her genitals. The malformations were corrected by means of a posterior sagittal approach, descending from the rectum to the anus without perineal dissection. The vaginal septum was resected thru the vulva. There is no evidence of recurrence of the recto-vaginal fistula.

Is it possible folic acid reduce anorectal malformations ethylenethiourea induced in rats?

PURPOSE: To investigate the effect of folic acid (FA) in an experimental model of anorectal malformations (ARMs) ethylenethiourea (ETU) induced.METHODS:Eight female Wistar rats were divided randomly in two groups. Group A - ETU; Group B - FA+ETU; Dams from group B received daily, since two weeks before pregnancy to the end of pregnancy, FA (50mg/kg) by gavage. Dams from groups A and B, received 1% ETU (125mk/kg) by gavage on gestational day (GD) 11. Their fetuses were harvested by cesarean section on GD21 and were examined looking for ARMs. The thickness of anal stratified squamous epithelium (ASSE) and intestinal epithelium (IE) were analyzed. p<0.05*.RESULTS:One hundred and one embryos were harvested. The number of embryos; number of ARMs; mean statistical % (± SD) were determined to be, respectively: ETU - 49 [30;65% (±24%)] versus FA+ETU - 52 [1;02% (±3%)] (p=0.025). AMRs were significantly lower in FA+ETU group than in ETU group (p=0.025). The thickness (µm) of ASSE (± SD) and IE (± SD) were measured, respectively: ETU - [27.75 (±0.56) and 18.88 (±0.93)] versus FA+ETU - [28.88 (±0.61) and 21.11 (±0.16)] (p=0.001). The thickness of IE was significantly enlarged when FA was given (p=0.001).CONCLUSION:Folic acid reduces the number and enlarged the IE of ARMs ETU-induced.

Deficiência de hormônio de crescimento em um paciente com síndrome de VACTERL / Growth hormone deficiency in a patient with VACTERL syndrome

A Síndrome de VACTERL é um conjunto de malformações congênitas, que necessita para o diagnóstico pelo menos três das seguintes alterações: malformações vertebrais, atresia anal, anomalias cardiovasculares, fístula traqueoesofágica, atresia esofágica, malformações renais e displasia dos membros. É relatado caso de paciente com Síndrome de VACTERL e deficiência de hormônio de crescimento. A revisão da literatura aborda uma possível associação entre esses dois diagnósticos clínicos (AU)

The VACTERL syndrome is a set of congenital malformations, which requires at least three of the following changes to be diagnosed: vertebral defects, anal atresia, cardiovascular anomalies, tracheoesophageal fistula, esophageal atresia, renal malformations and dysplasia of the limbs. Here we report the case of a patient with VACTERL syndrome and deficiency of growth hormone. A literature review discusses the possible association between these two clinical diagnoses (AU)

Epididymitis in Patients with Anorectal Malformations: A Cause for Urologic Concern

Introduction Epididymitis in patients with anorectal malformation (ARM) represents a unique problem because unlike the general population, an underlying urinary tract problem is frequently identified. We review our experience with epididymitis in ARM population with an emphasis on examining urologic outcomes. Materials and Methods We performed a retrospective review of male patients with ARM cared for from 1980 to 2010. Clinical and pathologic variables recorded included age at presentation, recurrence, associated urologic anomalies, incidence of ureteral fusion with mesonephric ductal structures, glomerular filtration rate and urodynamic parameters. Results Twenty-six patients were identified with documented episodes of epididymitis. Renal injury was noted in five patients (19%), all of whom were diagnosed with neurogenic bladder (NGB) several years after anorectoplasty. NGB was found in ten patients (38%) in our series. Ectopic insertion of ureter into a mesonephric ductal structure was discovered in five patients (19%). Twelve patients (46%) had recurrent episodes of epididymitis, with seven of these patients (58%) being diagnosed with NGB. Two patients in the pubertal group presented with a history of epididymitis and complained of ejaculatory pain. Conclusion Epididymitis in a patient with ARM warrants a comprehensive urologic investigation, particularly in recurrent episodes. Attempts at surgical intervention (e.g. vasectomy) should be avoided until functional assessment of the urinary tract has occurred. Failure to recognize this association may lead to potentially avoidable complications and morbidity. Long term urological follow up of these patients is warranted to identify at risk patients and minimize renal deterioration .

Surco perineal en ginecología infantil: reporte de 2 casos clínicos / Perineal groove in pediatric gynecology: a report of 2 cases

Introduction: the perineal groove is a very uncommon anorectal anomaly. It is the result of an unknown embryology anomaly. The perineal groove is a wet sulcus extending from de fourchette to the anus. It is a benign pathology and tends to resolve spontaneously. Objective: We report two cases of girls diagnosed with perineal groove and their follow up. Cases reports: The first case is an 18 days old baby girl, that during her first clinical examination there was found a painless lineal lesion in the perineum from the fourchette to the anus, which created a big anxiety in her family. She was cared at the Pediatric Gynecology Unit, with local lubrication, doing well with the epithelization of it. The second case is an 8 year-old girl who consulted because, when being a child, she was diagnosed with a perineal lesion, but she didn't receive any special treatment and now she feels some aches in the perineum. Conclusions: The perineal groove is a benign entity pretty unknown by general practitioners or pediatricians. It is important to be up to date with this condition to avoid alarming misinterpretations.

Introducción. El surco perineal es una malformación poco frecuente, de etiología desconocida, consiste en una ranura en la línea media del periné desde la horquilla vulvar al ano, es benigna y tiende a la resolución espontánea. Objetivos: Reportar el diagnóstico y evolución de dos pacientes con surco perineal. Casos clínicos: Caso 1. Recién nacida de 18 días que previo al alta de maternidad se pesquisó una lesión lineal no dolorosa desde la horquilla vulvar al ano, lo que generó gran inquietud en su familia. En Ginecología Infantil se confirmó el diagnóstico, se manejó con lubricación del área genital evolucionando a la epitelización del surco. Caso 2. Niña de 8 años consultó por que en controles de salud se diagnosticó una "fisura" entre la horquilla vulvar y el ano que no fue tratada y presentaba molestias inespecíficas en el periné. Se indicó resección quirúrgica, pero paciente evolucionó satisfactoriamente con lubricación de la zona. Conclusiones. El surco perineal es una entidad benigna que debe ser conocida por médicos de atención ambulatoria debido a la alarma que pueden generar sus diagnósticos diferenciales.

A rare case of perineal hamartoma associated with cryptorchidism and imperforate anus: case report / Caso raro de hamartoma perineal associado a criptorquidia e ânus imperfurado: relato de caso

A full-term male neonate with anorectal anomaly and external perineal anomalies was referred to our service. Physical examination showed an epithelized perineal mass with cutaneous orifices, which had urine fistulization, hipotrofic perineal musculature, bilateral congenital clubfoot, hipospadic urethra, criptorquidy bilateral with nonpalpable testis and imperforate anus. A colostomy was constructed immediately after birth. The child underwent excision of perineal mass, bilateral orchidopexy, Duplay neourethroplasty and coloanal anastomosis at 3 months of age. The histopathological examination of the perineal mass revealed a hamartoma.

Recém-nascido a termo do sexo masculino encaminhado ao nosso serviço por anomalia anorretal e anomalias perineais externas. O exame físico revelou massa perineal epitelizada, com orifícios cutâneos que apresentavam saída de urina, musculatura perineal hipotrófica, pé torto congênito bilateral, uretra hipospádica, criptorquidia bilateral com testículos não palpáveis e ânus imperfurado. Logo após o nascimento, o paciente foi submetido à colostomia. Aos 3 meses de idade, a criança foi submetida à excisão da massa perineal, orquidopexia bilateral, neouretroplastia a Duplay e anastomose coloanal. A análise anatomopatológica da massa perineal indicou hamartoma.

Health-related quality of life in children and adolescents undergoing surgery for Hirschsprung´s disease and anorectal malformations / Calidad de vida relacionada con la salud en niños y adolescentes con cirugía de enfermedad de Hirschsprung y malformaciones anorrectales

Purpose. The objective was to describe health related quality of life (HRQoL) after surgery for Hirschsprung's disease (HD) and anorectal malformations (ARMs) in children according to their own perception and that of their parents, by different age groups, the presence of functional disorders, and diet indication. Methods. This is a cross-sectional descriptive study. Participants were patients aged 2-18 years old and their parents. The study was conducted from June 2008 to May 2009. The instrument used was the PedsQL TM 4.0. Data were analyzed with SPSS version 11.5. Results. A total of 93 families gave their consent to participate. Higher scores indicated a better HRQoL. Parents showed a trend towards obtaining higher scores in the three scales analyzed. There were no differences observed in the various age groups. The lowest scores were obtained in incontinent, pseudo-incontinent and constipated patients with statistically significant differences according to the parents´ reports when compared to the patients who had no functional disorders. When analyzing dietary therapy, patients who were on a controlled protein and low sodium diet together with a suitable intestinal function obtained lower scores. Conclusion. The presence of postoperative functional disorders had a negative impact on the scores. Incontinent, pseudo-incontinent and constipated patients had the lowest scores, as well as those who had a stricter diet.

Introducción/Objetivos. Los resultados postoperatorios de la enfermedad de Hirschsprung y malformaciones anorrectales son satisfactorios, pero muchos pacientes mantienen disfunciones intestinales. Estudiar la calidad de vida relacionada con la salud facilita el conocimiento del estado de salud y mejora la elección de estrategias de tratamiento. Los objetivos del estudio fueron describir la CVRS en niños luego de la cirugía correctora definitiva, según su propia percepción y la de sus padres. A su vez, evaluar la calidad de vida relacionada con la salud según grupo etario, presencia de trastornos funcionales postoperatorios y la indicación dietoterápica. Materiales y métodos. Estudio descriptivo, transversal. Participaron niños de 2-18 años y sus padres al concurrir al consultorio en el período de junio 2008-mayo 2009. Una vez obtenidos el consentimiento y asentimiento informado se aplicó el cuestionario genérico PedsQLtm. Paquete estadístico SPSS11.5. Resultados. Participaron 93 pacientes, 32% con enfermedad de Hirschsprung y 68% con malformaciones anorrectales. La mediana de edad fue de 7 años (intervalo 2-18). Puntuaciones más altas indican mejor calidad de vida. Los padres obtuvieron puntuaciones superiores a las de los niños en todas las escalas analizadas. No se observaron diferencias según los distintos grupos etarios. Se obtuvieron puntuaciones más bajas, con diferencias estadísticamente significativas según los padres, en los pacientes incontinentes y constipados. Resultados similares se observaron en pacientes con indicación dietoterápica, especialmente las dietas adecuadas a patologías renal y digestiva. Las puntuaciones más bajas se encontraron en los dominios total y psicosocial. Conclusión. La presencia de incontinencia y constipación repercute negativamente sobre la calidad de vida de los niños, así como la realización de dietas con las puntuaciones más bajas cuanto más restrictivas son aquéllas.

Presentación de un caso con múltiples malformaciones congénitas: asociación VACTERL / A case with multiple congenital malformations: VACTERL association

La asociación VACTERL es un conjunto de malformaciones congénitas que ocurre en varias combinaciones, entre las cuales encontramos: malformaciones Vertebrales, atresia Anal, anomalías Cardiovasculares, fistula Traqueo esofágica, atresia Esofágica, malformaciones Renales y displasia de las extremidades (Limb), fundamentalmente en el hueso radial. Para su diagnóstico se requiere la presencia de, al menos, tres de los siete criterios enumerados y se realiza por medio de ecografía a partir de la semana 18 de gestación. Aun no se ha reconocido etiología específica para esta patología; se cree que es producto de una influencia teratogénica entre la cuarta y octava semana de gestación. El pronóstico de estos pacientes es muy pobre, ya que fallece el 50-85% de los niños en el primer año de vida, sobreviviendo después del primer año de vida solo un 12-15%.

VACTERL association is a group of birth defects occurring in various combinations, among which are: vertebral anomalies, anal atresia, cardiac defects, tracheo-oesophageal fistula with esophageal atresia, renal defects and limb dysplasia, mainly in the radial bone. To diagnostic is necessary at least three of the seven criteria listed and is performed by ultrasound after 18 weeks of gestation. Although no specific etiology has been recognized for this condition, is believed to be the result of undefined teratogenic influence acting between the fourth and eighth weeks of gestation. Prognosis for these patients is very poor, and who died on 50-85% of children in the first year and surviving after the first year of life only 12-15%.

Anomalias anorretais / Anorectal malformations

Pesquisa clinico-epidemiológica e terapêutica de pacientes portadores de anomalias anorretais AARsubmetidos a tratamento cirúrgico na Santa Casa de Misericórdia do Pará, período de janeiro de 2004 a dezembrode 2005. Método: estudo transversal de prontuários de 69 crianças, buscando-se dados como: tipo de anomalia,presença de malformações associadas, primeiro tratamento realizado e idade no momento destes. Posteriormente,20 pacientes foram entrevistados, sendo verificado se estes possuíam capacidade de expressar desejo de evacuar(Voluntary bowel movements); se apresentavam continência total, parcial (soiling) ou incontinência. Por último, foiverificado se apresentavam ou não constipação. Resultados: a maior frequência de fístula retovaginal em 43,5%das meninas; 43,3% dos meninos foi identificada, mais comumente, fístula retouretral; 50,7% dos pacientesapresentavam malformações associadas sendo as digestivas as mais comuns. Quanto ao resultado do tratamentocirúrgico, vimos que 80% das crianças apresentavam ?voluntary bowel movements?, sendo que 40% apresentavamcontinência total, 40% continência parcial e 20% incontinência e 45% dos pacientes apresentaram constipação.Considerações finais: cerca da metade das crianças apresentava anomalias associadas, sendo importante ainvestigação diagnóstica complementar em todos os pacientes. Os resultados do tratamento cirúrgico foramcompatíveis com a literatura internacional, demonstrando que as crianças vêm sendo tratadas, satisfatoriamente, noHospital da FSCMPA.

Evaluate epidemiologically and clinically the children with anorectal malformation that were subjectedto surgery in the Santa Casa de Misericórdia do Pará, from January 2004 until December 2005, also evaluating theresults of this treatment. Methods: information regarding the type of malformation, presence of associatedanomalies and the first surgical treatment were collected from the charts of the 69 patients subjected to surgery.Subsequently, 20 patients were interviewed about voluntary bowel movements (being able to express the wish todefecate), if they presented complete fecal continence, partial fecal continence (soiling) or total incontinence.Constipation was also evaluated. Results: the most prevalent type of ARM in girls was rectovaginal fistula(43,5%). In boys the most prevalent was rectourethral fistula (43,3%). Associated malformations were seen in50,7% of the children, affecting the digestive system mostly. Voluntary bowel movements were present in 80% ofthe patients. Complete fecal continence was found in 40%, partial continence in 40% and complete incontinence in20%. Constipation was seen in 45%. Final comments: half of the patients had associated anomalies which justifiesthe use of image diagnosis in the screening of all children. The results of the surgical treatment was compatiblewith international numbers showing that the children are receiving adequate treatment in this institution.
