RESUMEN

The absence of one or both testicles in the scrotal position is defined as cryptorchidism. It occurs in 1 - 8 % of full-term newborns and up to 45 % of preterm newborns. Its detection is of great importance due to its association with fertility disorders and the risk of malignancy. The National Endocrinology Committee of the Sociedad Argentina de Pediatría decided to prepare an update document on advances in the diagnosis and treatment of cryptorchidism that contributes to the performance of pediatric practice and allows recognition of conditions that may be accompanied by cryptorchidism, but need more evaluation and referral to a specialist, such as alterations/differences in sexual development, anorchia, genetic syndromes, among others. The first-line treatment is early orchiopexy before 12 to 18 months, always in the hands of pediatric surgeons.

Se define como criptorquidia, o criptorquidismo, a la ausencia de uno o ambos testículos en la posición escrotal. Se presenta en el 1-8 % de los recién nacidos de término y hasta en el 45 % de los pretérmino. Es de gran importancia su detección oportuna por su asociación con alteraciones de la fertilidad y el riesgo de malignidad. El Comité Nacional de Endocrinología de la Sociedad Argentina de Pediatría decidió elaborar un documento de actualización sobre los avances en el diagnóstico y tratamiento de la criptorquidia, útil para la práctica pediátrica y que permita identificar condiciones que puedan acompañarse de criptorquidia, pero que merezcan una evaluación más profunda y derivación al especialista (alteraciones/diferencias en el desarrollo sexual, anorquia, síndromes genéticos). El tratamiento de primera línea es la orquidopexia temprana (antes de los 12 a 18 meses), siempre en manos de cirujanos pediátricos.

RESUMEN

Congenital malformations of the posterior fossa (PF) encompass a wide spectrum of morphological anomalies that arise during embryonic development. This paper provides a narrative review of these most common disorders from a morphological approach based on the division into cystic (Dandy-Walker malformation, Blake's Pouch cyst, mega cisterna magna, arachnoid cyst, and cerebellar vermis hypoplasia) and non-cystic malformations (Joubert syndrome, rhomboencephalosynapsis, and pontocerebellar hypoplasia). The embryogenesis of PF structures is briefly outlined. While magnetic resonance imaging is the preferred modality for evaluation, computerized tomography and ultrasonography serve complementary roles. In conjunction with clinical aspects, specific radiological features, such as cerebellar vermis morphology, Torcular Herophili position, and the presence/absence of mass effect, are highlighted for accurate diagnosis. We also present some typical radiological findings in non-cystic malformations, such as molar tooth sign, diamondshaped fourth ventricle, and dragonfly-shaped cerebellum. This comprehensive review aims to assist radiologists, neuropediatricians, and general neurologists in recognizing and describing PF malformations, thereby facilitating appropriate management strategies.

As malformações congênitas da fossa posterior (FP) abrangem um amplo espectro de anomalias morfológicas que surgem durante o desenvolvimento embrionário. Este artigo fornece uma revisão narrativa desses distúrbios mais comuns a partir de uma abordagem morfológica baseada na divisão em malformações císticas (malformação de Dandy-Walker, cisto da bolsa de Blake, mega cisterna magna, cisto aracnoide e hipoplasia do vermis cerebelar) e não císticas (syndrome de Joubert, rombencefalossinapse e hipoplasia pontocerebelar). A embriogênese das estruturas da FP é brevemente descrita. Embora a ressonância magnética seja a modalidade preferida para avaliação, a tomografia computadorizada e a ultrassonografia desempenham funções complementares. Em conjunto com os aspectos clínicos, características radiológicas específicas, como a morfologia do vermis cerebelar, a posição da torcula Herophili e a presença/ausência de efeito de massa, são destacadas para um diagnóstico preciso. Apresentamos também alguns achados radiológicos típicos de malformações não císticas, como sinal do dente molar, quarto ventrículo em forma de diamante e cerebelo em forma de libélula. Esta revisão abrangente visa auxiliar radiologistas, neuropediatras e neurologistas gerais no reconhecimento e na descrição das malformações da FP, facilitando, assim, estratégias de manejo adequadas.

RESUMEN

AIM: The VACTERL association or Syndrome consists of Vertebral, Anorectal, Cardiac, Tracheo-Esophageal, Renal, and Limb defects. The diagnosis relies on the presence of at least three of these structural abnormalities. This study reports a single case of a patient with VACTERL Syndrome (VS), aiming to assist dentists in recognizing the general aspects, systemic changes, and oral care related to this condition. CASE REPORT: A 14-year-old female patient medically diagnosed with VS. The study evaluated the presence of systemic alterations, medication use, behavioral deviations, cognitive development, and oral aspects. The patient exhibited cardiovascular alterations including a ventricular septal defect (C), anal atresia (A), polydactyly (considered limb alteration-L), and scoliosis (a possible indication of vertebral anomalies-V). In the intraoral examination, findings included tooth crowding, enamel hypomineralization in several teeth, a deep and atretic palate, generalized gingivitis, bleeding, gingival hyperplasia, Class III malocclusion, and a right unilateral crossbite. CONCLUSION: Patients diagnosed with VACTERL syndrome experience significant systemic impairments. The research subject presented compromised oral health, challenges in dental management, delays in neuropsychomotor development, though these are not inherent to the syndrome. It is crucial to prevent oral diseases and provide early dental care for these patients to avoid the need for complex and invasive dental treatments due to systemic impairments.

RESUMEN

Brazil reported 18,282 suspected congenital Zika syndrome (CZS) cases up to 2018 and accounts for 61.4% of the total reported Zika cases in the Americas in the period. To detect high-risk areas for children with CZS in the city of Rio de Janeiro, we used cluster detection and thematic maps. We analyzed data using a Poisson model in Satscan 10.1.3 software. We also analyzed the records of children with CZS from 2015 to 2016 to describe the clinical and epidemiological maternal and child profile, as well as live births in 2016 and the social development index (SDI) by neighborhood. In 2015 and 2016, the incidence rates of CZS were 8.84 and 46.96 per 100,000 live births in the city, respectively. Severe congenital findings such as microcephaly and brain damage, osteoarticular impairment, ocular abnormalities, and hearing loss were observed in 47 children. The spatial distribution of CZS was concentrated in the north and west zones in heterogeneous neighborhoods. The neighborhoods with the highest occurrence of CZS cases were found to have the worst SDIs. Stascan detected three spatial clusters in the north zone, where the SDI is lower. The clusters presented high relative risks for CZS (7.86, 1.46, and 2.08), although they were not statistically significant. Our findings highlight a higher occurrence of CZS in areas with less favorable socioeconomic conditions.

RESUMEN

Diprosopus is a congenital anomaly in which partial or complete duplication of craniofacial structures occurs. Because it is rare, the mortality rate is high, and information concerning this anomaly is scarce. This study describes a case of human diprosopus in a 9-year-old male individual, who has severe complications associated with the central nervous, cardiovascular, respiratory, and digestive systems. Since birth, he has been monitored in a specialized hospital environment, where he has undergone several surgeries and multidisciplinary treatments. Regarding the craniofacial aspects, he had agenesis of the corpus callosum, floor of the nasal cavity, and floor of the anterior cranial fossa, in addition to the presence of bone dysplasia, ocular hypertelorism and cleft palate with nasal and oral teratoma. Regarding dental characteristics, the patient has duplication of the maxilla, mandible, tongue, and some teeth. After complementary imaging exams, several supernumerary teeth were found, with some being impacted and in complex regions, with an indication for extraction due to the risks of impaction, irruptive deviation, root resorption, and associated cystic or tumoral lesions. Because of the numerous complications, knowledge, and preparation of the entire team is necessary for the correct management of the case.

RESUMEN

BACKGROUND: Mortality from congenital heart disease has decreased considerably in the last two decades due to improvements in overall health care. However, there are barriers to access to healthcare in Latin America for this population, which could be related to factors such as healthcare system, policies, resources, geographic, cultural, educational, and psychological factors. Understanding the barriers to access to care is of paramount importance for the design and implementation of policies and facilitate the provision of care. AIM: The aim of the study was to investigate the perception of barriers to access to health care on parents/guardians of children with congenital heart disease in selected Latin American countries. METHODS: A descriptive, cross-sectional study, in which parents/guardians or primary caregivers of children with congenital heart disease was recruited to participate and surveyed. Once the informed consent process had been completed, a set of paper-based scales was used to collect data, namely socioeconomic and demographic information, the Barriers to Care for Children with Special Health Care Needs Questionnaire, and the General Health Questionnaire. RESULTS: In total, 286 participants completed the surveys, with an average age of 34.81 years and 73.4% being female. Mean score of overall barriers was 54.45 (minimum score 39, maximum score 195, higher scores show greater perception of barriers). In Mexico, the parents/guardians of children perceived fewer barriers to access (46.69), while Peru is the country where the most barriers were perceived (69.91). Nonpoor participants showed higher overall barrier perception scores (57.34) than poor participants (52.58). The regression analysis demonstrated the overall perception of barriers was positively associated with individual and social factors, such as educational level, contract status, household monthly income, and psychological well-being and with the country of the participants. CONCLUSIONS: Multiple factors are associated with the perception of barriers to accessing health care for children with congenital heart disease, including socioeconomic status, expectations, psychological well-being, and structural factors.

RESUMEN

Introducción. La duplicación del colédoco es una anomalía congénita poco frecuente. En la mayoría de los casos este defecto se asocia a cálculos en la vía biliar, unión pancreatobiliar anómala, pancreatitis, cáncer gástrico o colangiocarcinoma. Por esta razón, el diagnóstico y el tratamiento temprano son importantes para evitar las complicaciones descritas a futuro. Métodos. Se presenta el caso de una paciente de 30 años, con antecedente de pancreatitis aguda, con cuadro de dolor abdominal crónico, a quien se le realizaron varios estudios imagenológicos sin claro diagnóstico. Fue llevada a manejo quirúrgico en donde se documentó duplicación del colédoco tipo II con unión pancreatobiliar anómala. Resultados. Se hizo reconstrucción de las vías biliares y hepatico-yeyunostomía, con adecuada evolución postoperatoria y reporte final de patología sin evidencia de tumor. Conclusión. El diagnóstico se hace mediante ecografía endoscópica biliopancreática, colangiorresonancia o colangiopancreatografía retrógrada endoscópica. El tratamiento depende de si está asociado o no a la presencia de unión biliopancreática anómala o cáncer. Si el paciente no presenta patología neoplásica, el tratamiento quirúrgico recomendado es la resección del conducto con reconstrucción de las vías biliares.

Introduction. Double common bile duct is an extremely rare congenital anomaly. This anomaly may be associated with bile duct stones, anomalous biliopancreatic junction, pancreatitis, bile duct cancer, or gastric cancers. Thus, early diagnosis and treatment is important to avoid complications. Clinical case. We report a rare case of double common bile duct associated with an anomalous biliopancreatic junction in a 30-year-old female, with prior history of acute pancreatitis, who presented with chronic abdominal pain. She underwent several imaging studies, without clear diagnosis. She was taken to surgical management where duplication of the type II common bile duct was documented with anomalous pancreatobiliary junction. Results. Reconstruction of the bile ducts and hepatico-jejunostomy were performed, with adequate postoperative evolution and final pathology report without evidence of tumor. Conclusion. Diagnosis is usually performed by an endoscopic ultrasound, magnetic resonance cholangiopancrea-tography, or endoscopic retrograde cholangiopancreatography. Treatment depends on the presence of anomalus biliopancreatic junction or concomitant cancer. In cases without associated malignancy, resection of bile duct and biliary reconstruction is the recommended surgical treatment.

RESUMEN

ABSTRACT Objective: To describe the epidemiological profile and prevalence of live births with orofacial clefts in Brazil between 1999 and 2020. Methods: Descriptive study. The population corresponded to live births with isolated orofacial clefts in Brazil registered in the Live Birth Information System between 1999 and 2020. Descriptive variables were selected according to their availability and grouped into socioeconomic and demographic, maternal and child health care, and biological variables. Data were submitted to a descriptive analysis using the Software for Statistics and Data Science (STATA). Results: During the period, 33,699 children were born with orofacial clefts, and 82.1% (27,677) of them were isolated clefts. Regarding these cases, the majority were cleft lip and palate (9,619 or 34.7%), followed by cleft palate (9,442 or 34.1%), and by cleft lip (8,616 or 31.3%). Conclusions: Live births with orofacial clefts in Brazil were male, white, with birthweight ≥2,500 g and gestational age ≥37 weeks, born by cesarean section, and with Apgar scores ≥7. The cases were more frequent among mothers who were in their first and single pregnancy and had seven or more prenatal appointments. The mothers were 20 and 29 years old, had eight to ten years of study, and were single. The national prevalence of clefts was 4.24/10,000. The South and Southeast regions of Brazil had the highest prevalence, while the lowest prevalence was recorded in the Northeast and North regions. For the Federative Units, the highest and lowest prevalences were found, respectively, in Paraná and Acre.

RESUMO Objetivo: Descrever o perfil epidemiológico e a prevalência dos nascidos vivos com fissuras orofaciais no Brasil entre 1999 e 2020. Métodos: Estudo descritivo. A população correspondeu aos nascidos vivos com fissuras orofaciais isoladas no Brasil registrados no Sistema de Informação de Nascidos Vivos entre 1999 e 2020. As variáveis descritivas foram selecionadas de acordo com a sua disponibilidade e agrupadas em variáveis socioeconômicas e demográficas, de atenção à saúde materno-infantil e biológicas. Os dados foram submetidos a análise descritiva utilizando o Software for Statistics and Data Science (STATA). Resultados: No período, 33.699 indivíduos nasceram com fissura orofacial no Brasil, e 82,1% (27.677) deles foram fissuras isoladas. Com relação a esses casos, a maioria foi de fissuras de lábio e palato (9.619 ou 34,7%), seguidas por fissura de palato (9.442 ou 34,1%) e por fissura de lábio (8.616 ou 31,1%). Conclusões: O perfil epidemiológico dos nascidos vivos com fissuras orofaciais no Brasil foi de nascidos do sexo masculino, da raça/cor branca, por parto cesáreo, com peso ao nascer ≥2,500 g, idade gestacional ≥37 semanas e com índices de Apgar ≥7. Os casos foram mais frequentes entre mães que estavam na primeira gestação, única e que haviam realizado sete ou mais consultas de pré-natal. As mães, com maior frequência, tinham entre 20 e 29 anos, apresentavam oito ou mais anos de estudo, eram solteiras e residiam em cidades do interior. A prevalência nacional de fissuras foi de 4,24/10.000. As Regiões Sul e Sudeste apresentaram as maiores prevalências, enquanto as menores foram registradas nas Regiões Nordeste e Norte. Para as Unidades Federativas, as maiores e menores prevalências foram encontradas, respectivamente, no Paraná e no Acre.

RESUMEN

Introducción: el dacriocistocele es una malformación congénita rara, secundaria a la obstrucción del conducto nasolagrimal; tiene una incidencia de 0,1 % de pacientes con obstrucción congénita del conducto nasolagrimal y se encuentra bilateralmente hasta en 25 % de casos. Caso clínico: lactante femenina de dos meses con celulitis periorbitaria derecha preseptal no asociada con lesión de entrada y diagnóstico inicial de dacriocistitis derecha. Al examen físico de ingreso, en el ojo derecho se evidencia gran masa abscedada en saco lagrimal; en el ojo izquierdo, un área indurada y leve reflujo a la presión del saco lagrimal. Se realiza tomografía computarizada de órbitas con hallazgos compatibles con dacriocistocele bilateral. Discusión y conclusiones: conocer la presentación y posibles complicaciones asociadas con esta patología previene una morbilidad importante al paciente. La mayoría de los casos de dacriocistocele se pueden manejar médicamente, sin embargo, aquellos asociados con complicaciones requieren de manejo quirúrgico oportuno.

Introduction: Dacryocystocele is a rare congenital malformation secondary to na-solacrimal duct obstruction. It has an incidence of 0.1% of patients with congenital nasolacrimal duct obstruction, being found bilaterally in up to 25% of cases. Case Report: Two-month-old female infant with preseptal right periorbital cellulitis not associated with an entrance lesion, with an initial diagnosis of right dacryocystitis. On physical examination, a large abscessed mass in the lacrimal sac was eviden-ced in the right eye; in the left eye, there was an indurated area and slight reflux to the lacrimal sac pressure. Computed tomography of the orbits was performed with findings compatible with bilateral dacryocystocele. Discussion and conclusions: Knowing the presentation and possible complications associated with this pathology prevents significant patient morbidity. Most cases of dacryocystocele can be mana-ged medically, however, cases associated with complications require timely surgical management.

RESUMO O anquiloblefáro filiforme congênito é uma rara anomalia congênita, caracterizada por uma fusão palpebral, parcial ou completa, cuja incidência é de 4,4 por 100 mil recém-nascidos. Normalmente, o anquiloblefáro filiforme congênito constitui uma malformação solitária, de ocorrência esporádica, no entanto, pode estar associado a outras malformações. O pediatra possui papel imprescindível para observar as alterações clínicas do recém-nascido e dar orientação para o tratamento adequado. O objetivo deste estudo foi relatar o caso de recém-nascido de termo que teve diagnóstico precoce de anquiloblefáro filiforme congênito associado a outras malformações congênitas, tendo desfeito as aderências em procedimento cirúrgico oportuno, evitando-se a evolução para futuras complicações visuais do paciente.

ABSTRACT Ankyloblepharon filiforme adnatum is a rare congenital anomaly, characterized by partial or complete palpebral fusion, with an incidence of 4.4 per 100,000 newborns. Normally, ankyloblepharon filiforme adnatum constitutes a solitary malformation, with sporadic occurrence, however, it can be associated with other malformations. Pediatricians play an essential role in observing clinical changes in newborns and providing guidance on appropriate treatment. The this study aims to report the case of a full-term newborn who had an early diagnosis of ankyloblepharon filiforme adnatum associated with other congenital malformations.

RESUMEN

SUMMARY OBJECTIVE: We aimed to compare the etiology and perinatal outcomes of non-immune hydrops fetalis diagnosed early- and late-onset at our hospital. METHODS: The records of the patients who applied to our department were reviewed, and we reached 42 non-immune hydrops fetalis cases retrospectively and examined the medical records. Hydrops diagnosis week, birth week, accompanying anomalies, and perinatal outcomes were compared as ≤12 weeks (early-onset) and >12 weeks (late-onset). RESULTS: The prevalence of non-immune hydrops fetalis was 0.05%, and the median week of diagnosis for hydrops was 18 weeks. Consanguinity (16.7%) was found in seven pregnancies, and the other seven patients (16.7%) had a history of hydrops in previous pregnancies. Anomalies of the skeletal system, central nervous system, and gastrointestinal tract accounted for 66.7% of ≤12 weeks in non-immune hydrops fetalis cases. Cardiac abnormalities were more common (26.7%) in patients at > 12 weeks (p=0.078). A statistically significant difference was found between the distribution of week of birth and week of diagnosis (p=0.029). Notably, 66.7% of patients diagnosed before week 12 and 23.3% of patients diagnosed after week 12 delivered their babies before week 24. Spontaneous intrauterine death occurred before week 12 in 45.5% (n=5) of non-immune hydrops fetalis and after week 12 in 39.1% (n=9) of non-immune hydrops fetalis. Notably, 69.2% (n=9) of the patients who had prenatal invasive testing resulted in normal karyotype. CONCLUSION: In this study, most of the fetuses diagnosed with early-onset non-immune hydrops fetalis were born in the first 24 weeks. Additionally, live birth rates and cardiac anomalies were observed to be higher in late-onset non-immune hydrops fetalis.

RESUMEN

ABSTRACT BACKGROUND: Congenital Anomalies of the Upper Limb (CAUL) are a group of structural or functional abnormalities that develop during intrauterine life and can lead to limb dysfunction. OBJECTIVES: To analyze the prevalence of congenital anomalies of the upper limbs in Brazil and assess maternal and neonatal variables. DESIGN AND SETTING: A cross-sectional, descriptive study was conducted on congenital upper limb malformations among live births across Brazil. METHODS: The study spanned from 2010 to 2019. Data were sourced from the Department of Informatics of the Unified Health System (DATASUS) and the Live Birth Information System (SINASC) portal. Analyses focused on the information reported in field 41 of the Live Birth Declaration Form entered into the computerized system. RESULTS: The most common anomaly in Brazil was supernumerary fingers, classified as ICD-Q69.0, affecting 11,708 children, with a prevalence of 4.02 per 10,000 live births. Mothers aged over 40 years had a 36% higher prevalence of having children with CAUL than mothers under 40 years old (OR = 1.36; 95% CI 1.19-1.56). Newborns weighing ≥ 2,499 g were 2.64 times more likely to have CAUL compared to those weighing ≥ 2,500 g (OR = 2.64; 95% CI 2.55-2.73). CONCLUSION: There was an observed increase in the reporting of CAUL cases over the decade studied. This trend serves as an alert for health agencies, as understanding the prevalence of CAUL and its associated factors is crucial for preventive medicine.

RESUMEN

La anencefalia es una anomalía gestacional que produce la ausencia de gran parte del cerebro y del cráneo; aunque se desconoce el motivo principal de su aparición, puede estar relacionado con toxinas ambientales, y pobre ingesta de ácido fólico durante el embarazo. Los fetos que padecen de esta malformación, en su mayoría, no llegan a nacer vivos o mueren a las pocas horas. Se presentó una paciente recibida en emergencia en el Centro de Atención Integral Materno Infantil, municipio Ixchiguan, departamento de San Marcos, Guatemala con embarazo a término, según refirió la paciente, sin atención prenatal, dolor en hipogastrio y pérdida de líquido amniótico de un día de evolución. Siendo este un defecto genético multifactorial, para el cual no existe tratamiento, el único recurso para su prevención fue brindar una atención prenatal pormenorizada con énfasis especial en el programa de genética para la detección precoz de anomalías congénitas.

Anencephaly is a gestational anomaly that produces the absence of a large part of the brain and skull; although the main reason for its appearance is unknown, it may be related to environmental toxins and poor intake of folic acid during pregnancy. Most of the fetuses that suffer from this malformation are not born alive or die within a few hours. We present a female patient who was received in the emergency service of the Comprehensive Maternal and Child Care Center in Ixchiguan municipality, San Marcos department, Guatemala, with a full-term pregnancy, as reported by the patient, without prenatal care, hypogastric pain and loss of amniotic fluid of one day of evolution. Since there is no treatment for this multifactorial genetic defect, the only resource for its prevention was to provide detailed prenatal care with special emphasis on the genetics program for the early detection of congenital anomalies.

RESUMEN

Introducción: En Cuba, los defectos congénitos constituyen la segunda causa de muerte en niños menores de un año, por lo cual ocupan un lugar prioritario en los programas médicos sociales del país. Objetivo: Evaluar el comportamiento epidemiológico del diagnóstico prenatal de los defectos congénitos en Holguín, Cuba. Métodos: Se realizó un estudio descriptivo y transversal de la epidemiología de los defectos congénitos en la provincia de Holguín, Cuba, en el periodo de enero 2011- junio de 2020. Resultados: Los años con mayor número de defectos congénitos diagnosticados fueron: 2011, 2012, 2017 y 2018 con 308, 253, 290 y 236 pacientes, respectivamente. Los defectos congénitos más frecuentes fueron: cardiovasculares (comunicación interventricular, canal auriculoventricular, transposición de grandes vasos e hipoplasia de cavidades), renales (pielocaliectasia, hidronefrosis, riñones poliquísticos), y del sistema nervioso central (ventriculomegalia, hidrocefalia). El grupo de edad materna donde se realizó mayor número de diagnósticos fue entre 20-24 años, la mayoría en el segundo trimestre de la gestación; en el primer trimestre, el mayor número de defectos congénitos correspondió a los defectos de pared anterior. La tasa de mortalidad infantil por defectos congénitos se mantuvo estable en la mayoría de los años estudiados. Conclusiones: La estabilidad y perfeccionamiento del programa de diagnóstico prenatal de los defectos congénitos, y el asesoramiento genético adecuado, han tenido un resultado epidemiológico favorable en la provincia.

Introduction: congenital defects in Cuba are the second cause of death in children under one year of age that is why they occupy a priority place in the social medical programs of the country. Objective: to evaluate the epidemiological manifestation of the prenatal diagnosis of congenital defects in Holguín, Cuba. Methods: a descriptive and cross-sectional study of the epidemiology of birth defects was carried out in Holguín province, Cuba from January 2011 to June 2020. Results: the years with the highest number of diagnosed birth defects were 2011, 2012, 2017 and 2018 with 308, 253, 290 and 236 patients, respectively. The most frequent birth defects were cardiovascular (ventricular septal defect, atrioventricular canal, transposition of the great vessels and hypoplasia of cavities), renal (pyelokaliectasia, hydronephrosis and polycystic kidneys), and central nervous system (ventriculomegaly and hydrocephalus). The maternal age group in which the highest number of diagnoses was made was between 20-24 years, mostly in the second trimester of pregnancy; the largest number of congenital defects in the first trimester corresponded to anterior wall defects. The infant mortality rate due to congenital defects remained stable in most of the years studied. Conclusions: the stability and improvement of the prenatal diagnosis program for congenital defects, as well as an adequate genetic counseling, have had a favourable epidemiological result in the province.

RESUMEN

Resumen La atresia laríngea es una malformación congénita de la vía aérea, que se presenta por la falta de recanalización de la luz laríngea durante la embriogénesis. Se requiere de la detección de hallazgos ecográficos característicos durante la gestación para considerar este diagnóstico. En este artículo, se presenta el caso de una gestación de 39,2 semanas con pobres controles prenatales y única ecografía gestacional tardía que no reportaba anomalías. Al nacimiento, el feto estaba no vigoroso e hipotónico, con insuficiente esfuerzo respiratorio, cianosis bucal y puntajes de Apgar 4-4-0, por lo que realizaron maniobras de reanimación con gran dificultad para lograr ventilación y múltiples intentos de intubación endotraqueal fallidos, aunque el personal médico indicó que a pesar de identificar las cuerdas vocales les fue imposible el paso del tubo. Finalmente, el neonato fallece. Ante la sospecha de malformación en la vía respiratoria superior, solicitan al servicio de patología realizar autopsia clínica para confirmar causa de la muerte.

Abstract Laryngeal atresia is a congenital malformation of the airway, which occurs due to the lack of recanalization of the laryngeal lumen during embryogenesis. The detection of characteristic sonographic features during pregnancy is required to consider this diagnosis. In this article we present the case of a 39.2-week gestation with poor prenatal controls and a single late gestational ultrasound that did not report abnormalities. At birth, the fetus was non-vigorous and hypotonic, with poor respiratory effort, oral cyanosis and Apgar scores of 4-4-0, for which it underwent resuscitation maneuvers with great difficulty in achieving ventilation and multiple failed endotracheal intubation attempts, although the medical staff indicates that despite identifying the vocal cords, it was impossible for them to pass the tube. Finally the newborn dies. Suspecting a malformation in the upper respiratory tract, request the pathology service to perform a clinical autopsy to confirm the cause of death.

RESUMEN

Intestinal nonrotation is a rare embryonic developmental anomaly with a reported incidence of up to 0.5% in autopsies. Given the asymptomatic course, the diagnosis may be late, so it becomes an incidental finding. This study presents the most common imaging characteristics to familiarize readers with this pathology. We describe the case of a 73-year-old patient who consulted for pain in the right inguinal region associated with the sensation of a mass. There were no significant findings on physical examination. An abdominal tomography with contrast was requested as a study method, identifying a reversal of the superior mesenteric artery/superior mesenteric vein relationship with the cecum, appendix, and ileocecal valve in the left flank and mesogastrium. A displacement of thin intestinal loops towards the right hemiabdomen was also noted.

La no rotación intestinal es una anomalía del desarrollo embrionario poco frecuente con una incidencia reportada de hasta el 0,5 % en autopsias. El diagnóstico puede ser tardío dado el curso asintomático, por lo que se convierte en un hallazgo incidental. El objetivo de este estudio es dar a conocer las características por imagen más comunes para familiarizar a los lectores con esta patología. Se presenta el caso de un paciente de 73 años que consultó por dolor en la región inguinal derecha asociado a sensación de masa. En el examen físico no hubo hallazgos significativos. Se solicitó una tomografía abdominal con contraste como método de estudio y se identificó una inversión de la relación entre la arteria y vena mesentérica superior con la presencia de ciego, apéndice y válvula ileocecal en el flanco izquierdo y mesogastrio. Adicionalmente, se observó un desplazamiento de asas intestinales delgadas hacia el hemiabdomen derecho.

RESUMEN

BACKGROUND: Neonatal surgery is one of the most specialized and demanding areas of pediatric surgery due to the specific anatomical and physiological characteristics of this vulnerable group of patients. This study aimed to present the experience of 10 years of neonatal surgical management in a secondary care perinatal hospital in Mexico. METHODS: We conducted a descriptive, observational, cross-sectional, and retrospective study in a perinatal hospital in Toluca, Mexico, from August 01, 2012, to July 31, 2022. We included patients who underwent surgery within the hospital facilities by the Service of Pediatric Surgery. We studied demographic, clinical, and surgical variables and performed descriptive and inferential statistics. RESULTS: A total of 551 patients underwent surgery during this period with a prevalence of 0.5%. The number of patients operated in the neonatal period was 497 (90.1%). Forty-eight pathologies were recorded, with a predominance of congenital malformations in 64.6% and prenatal diagnosis in 40.5% of cases. The survival rate was 89.7%. In the bivariate analysis of mortality, we found an inverse relationship between weight and gestational age (p < 0.05). CONCLUSION: Although not a local or national reference center, the hospital where the study was conducted treats various congenital and acquired diseases, with a mortality rate that tends to decrease, close to the international average, and lower than national reports.

INTRODUCCIÓN: La cirugía pediátrica en la atención del recién nacido es una de las ramas más especializadas y demandantes debido a las particulares características anatómicas y fisiológicas de este vulnerable grupo de pacientes. El objetivo de este estudio fue presentar la experiencia de diez años de manejo quirúrgico neonatal en un hospital perinatal de segundo nivel de atención en México. MÉTODOS: Se llevó a cabo un estudio descriptivo, observacional, transversal y retrospectivo, en un hospital perinatal de Toluca, México, del 01 de agosto de 2012 al 31 de julio de 2022. Se incluyeron los pacientes sometidos a cirugía dentro de las instalaciones del hospital por parte del servicio de Cirugía Pediátrica. Se estudiaron variables demográficas, clínicas y quirúrgicas, realizando estadística descriptiva e inferencial. RESULTADOS: Un total de 551 pacientes fueron intervenidos quirúrgicamente en este periodo, con una prevalencia de 0.5%. La cantidad de pacientes operados en el periodo neonatal fue de 497 (90.1%). Se presentaron 48 patologías con predominio de las congénitas en el 64.6% y diagnóstico prenatal en el 40.5% de los casos. La supervivencia de los pacientes fue del 89.7%. En el análisis bivariado de mortalidad se encontró una relación inversa con el peso y edad gestacional (p < 0.05). CONCLUSIONES: En el hospital donde se realizó el estudio, a pesar de no ser un centro de referencia local o nacional, se atiende una amplia diversidad de padecimientos congénitos y adquiridos, con una mortalidad con tendencia a disminuir cercana a la media internacional y menor que los reportes nacionales.

RESUMEN

Objective The present study aims to analyze the use of shoulder imbalance as a parameter for scoliosis screening as well as its relationship with other parameters of physical examination. Methods This study assesses a smartphone application that analyzes several parameters of the physical examination in adolescent idiopathic scoliosis. Medical and non-medical examiners applied the screening tool in students in a public school and in a private sports club. After data collection, interobserver correlation was done to verify shoulder imbalance and to compare shoulder imbalance with Adam's bending test and with trunk rotation. Results Eighty-nine participants were examined, 18 of whom were women and 71 of whom were men. Two subjects were excluded from the analysis. The mean age of subjects from the public school was 11.30 years and, for those from the sports club, it was 11.92 years. The examiners had poor-to-slight interobserver concordance on shoulder asymmetry in the anterior and posterior view. No significant statistical correlation was found between shoulder asymmetry and positive Adam's forward bending test. Conclusion Our preliminary study shows that the shoulder asymmetry has a poor correlation with the Adam's forward bending test and measuring trunk rotation using a scoliometer. Therefore, the use of shoulder imbalance might not be useful for idiopathic scoliosis screening. Level of Evidence III; Diagnostic Study.
