Descripción de las intervenciones broncoscópicas en estenosis traqueales posterior a infección por COVID-19 / Description of Bronchoscopic Interventions in Post-COVID Tracheal Stenosis

Introducción: La infección por SARS-CoV-2 puede presentar síndrome de distrés res-piratorio agudo con requerimiento de ventilación mecánica prolongada y retraso en la realización de traqueostomía. Esto trae como consecuencia un incremento en casos de estenosis traqueal y la necesidad de métodos menos invasivos para su abordaje. Métodos: Estudio descriptivo de corte transversal, desde marzo 2020 hasta diciem-bre 2021 en el Hospital Universitario Nacional de Colombia, en adultos con estenosis traqueal postintubación asociado SARS-CoV-2. Se realizó análisis univariado entre los grupos con infección o no por SARS-CoV-2 como control, y reintervención, grado de estenosis, uso de inyección intramucosa con dexametasona intratraqueal o múltiples estenosis como desenlaces de importancia. Se usó test exacto de Fisher, t Student y Man-Whitney según la naturaleza de variables. Se consideró p estadísticamente significativo menor a 0.05.Resultados: Se identificaron 26 pacientes, 20 tenían COVID-19 y 6 no. Se encontraron diferencias en edad (p=0,002), epilepsia (p=0,007) y estenosis múltiple (p= 0,04). En 85% de los casos se utilizó láser blue más dilatación con balón pulmonar, en 35% inyección intramucosa con dexametasona intratraqueal y reintervención en 35%, sin diferencias significativas entre grupos. Conclusiones: Se observó un incremento tres veces mayor de pacientes con estenosis múltiple en el grupo de infección por COVID-19, así mismo se encontró que el método más utilizado en este grupo para la recanalización fue el uso de láser blue más dilatación con balón pulmonar y la innovación en el uso de inyección intramucosa.

Introduction: SARS-CoV-2 infection can lead to acute respiratory distress syndrome with a prolonged need for mechanical ventilation and delayed tracheostomy, resulting in an increase in cases of tracheal stenosis and the necessity for less invasive approaches.Methods: A descriptive cross-sectional study was conducted from March 2020 to December 2021 at the Hospital Universitario Nacional de Colombia, focusing on adults with post-intubation tracheal stenosis associated with SARS-CoV-2. Univariate analysis was performed between groups with or without SARS-CoV-2 infection as a control, considering reintervention, degree of stenosis, use of intratracheal steroids, or multiple stenoses as important outcomes. Fisher's exact test, Student's t-test, and Mann-Whit-ney test were employed based on the nature of variables. A p-value less than 0.05 was considered statistically significant.Results: A total of 26 patients were included, with 20 having COVID-19 and 6 without. Significant differences were found in age (p=0.002), epilepsy (p=0.007), and multiple stenosis (p=0.04). In 85% of cases, laser blue plus balloon pulmonary dilation was used, intratracheal dexamethasone in 35%, and reintervention in 35%, with no significant differences between groups.Conclusions: A threefold increase in subglottic stenosis was observed during the SARS-CoV-2 pandemic, with more instances of multiple stenosis and predominantly the use of laser blue plus balloon pulmonary dilation as a successful recanalization technique. There was a higher use of intratracheal dexamethasone in this group compared to oth-er pathologies causing tracheal stenosis.

Psychometric properties of The Maastricht Upper Extremity Questionnaire: systematic review and meta-analysis / Propriedades psicométricas do The Maastricht Upper Extremity Questionnaire: revisão sistemática e meta-análise

ABSTRACT BACKGROUND AND OBJECTIVES: With the necessity to assess musculoskeletal complaints caused by computer use, The Maastricht Upper Extremity Questionnaire (MUEQ) was created, which aims to assess musculoskeletal complaints of the upper limbs, shoulder complex and cervical spine in computer users. However, there is currently no comprehensive summary in the scientific literature on the psychometric properties of the MUEQ. The objective of this study was to conduct a synthesis of all available scientific evidence that has analyzed the psychometric properties of the MUEQ. CONTENTS: This study followed the PRISMA recommendations. The bibliographic search was carried out in the following databases: MEDLINE (via VHL), Embase, LILACS (via VHL), Pubmed, PsycINFO, Scielo, Academic Search Premier, CINAHL, Rehabilitation & Sports Medicine Source, MEDLINE Complete, Web of Science CENTRAL, Scopus and SPORTDiscus. Studies that addressed the psychometric properties of the MUEQ were included, as long as they were original articles of research carried out with human beings and indexed in the databases used. The studies were selected in two phases, with two independent reviewers. A total of 6 articles were included in the analysis. The evidence based on internal structure showed acceptable results. The reliability indexes ranged from α=0.52 to α=0.84, and ICC/composite reliability > 0.70 in the analyzed studies, classified as "good" and "excellent," respectively. CONCLUSION: In general, this research found a lack of detail on the process of content validity and evidence related to external variables and the description of the sample. These problems extended to the evidence based on the internal structure and reliability of the MUEQ, which did not reach levels considered acceptable to ensure its adequacy and accuracy.

RESUMO JUSTIFICATIVA E OBJETIVOS: Com a necessidade de avaliar as queixas musculoesqueléticas ocasionadas pelo uso de computadores, foi criado o The Maastricht Upper Extremity Questionnaire (MUEQ), cujo objetivo foi avaliar as queixas musculoesqueléticas relativas aos membros superiores, ao complexo do ombro e à cervical em usuários de computadores. No entanto, atualmente não existe uma sumarização abrangente, na literatura científica, sobre as propriedades psicométricas do MUEQ. O objetivo deste estudo foi realizar uma síntese de evidências científicas disponíveis que analisaram as propriedades psicométricas do MUEQ. CONTEÚDO: Este estudo seguiu as recomendações do PRISMA. A busca bibliográfica foi realizada nas bases de dados Medline (via BVS), Embase, LILACS (via BVS), Pubmed, PsycINFO, Scielo, Academic Search Premier, CINAHL, Rehabilitation & Sports Medicine Source, MEDLINE Complete, Web of Science CENTRAL, Scopus e SPORTDiscus. Foram incluídos estudos que abordaram as propriedades psicométricas do MUEQ, desde que fossem artigos originais de pesquisas desenvolvidas com seres humanos e indexados nas bases utilizadas. A seleção dos estudos ocorreu em duas fases, com dois revisores independentes. Foram incluídos 6 artigos/publicações na análise. A evidência baseada na estrutura interna apresentou resultados aceitáveis. Os índices de fidedignidade variaram de α=0,52 a α=0,84 e ICC/confiabilidade composta foram maiores que 0,70 nos estudos selecionados, classificados como "bom" e "excelente", respectivamente. CONCLUSÃO: De um modo geral, esta pesquisa constatou a falta de detalhamento sobre o processo de validade de conteúdo e de evidências relacionados a variáveis externas e à descrição da amostra. Esses problemas se estenderam à evidência baseada na estrutura interna e à confiabilidade do MUEQ, que não alcançaram níveis considerados aceitáveis para garantir sua adequação e precisão.

Percentiles de peso, talla e índice de masa corporal de escolares de Mendoza. Comparación con la referencia de la Organización Mundial de la Salud / Body mass index, weight, and height percentiles in school-aged children from Mendoza. A comparison with the WHO reference

Introducción. La Organización Mundial de la Salud (OMS) recomienda el uso de tablas de referencia para monitorear el crecimiento y estado nutricional de niños, niñas y adolescentes. El peso corporal, la talla y el índice de masa corporal (IMC) son las variables más utilizadas. El presente trabajo tiene como objetivos estimar los percentiles de peso, talla e IMC de escolares (2009-2011) residentes en el departamento San Rafael (Mendoza) y compararlos con la referencia internacional de la Organización Mundial de la Salud, a fin de establecer su pertinencia para la evaluación del crecimiento y estado nutricional de dicha población. Población y métodos. Se realizó un estudio antropométrico transversal en 3448 escolares de entre 4,00 y 13,49 años de edad. Se utilizó el programa LMS ChartMarker Pro para calcular los valores percentilares de peso/edad, talla/edad e IMC/edad, por sexo y edad, y se compararon con las curvas de la OMS. Además, se calcularon diferencias porcentuales (D%) para estimar las diferencias y su significación estadística mediante prueba de Wilcoxon. Resultados. La población de San Rafael mostró, en varones y mujeres, valores percentilares superiores de peso e IMC (D% ≈7 % y 9 %, respectivamente), y menores de talla (D% ≈0,8 %) que los de la OMS (p <0,05). Conclusión. Las diferencias encontradas alertan sobre el empleo de la referencia OMS en la población escolar de San Rafael, ya que sobreestimaría las prevalencias de sobrepeso, obesidad y desnutrición crónica, y subestimaría la de desnutrición aguda y global. Esta situación resalta la importancia de contar con una referencia local.

Introduction. The World Health Organization (WHO) recommends the use of reference tables to monitor the growth pattern and nutritional status of children and adolescents. Body mass index (BMI), weight, and height are the most commonly used variables. The objective of this study was to estimate the BMI, weight, and height percentiles for school-aged children (2009-2011) living in the department of San Rafael (Mendoza) and compare them to the international World Health Organization reference to establish their relevance for the evaluation of the growth pattern and nutritional status of this population. Population and methods. A cross-sectional anthropometric study was conducted in 3448 school-aged children aged 4.00 to 13.49 years. The LMS ChartMarker Pro software was used to estimate the BMI- for-age, weight-for-age, and height-for-age percentiles, by sex and age, and they were compared with the WHO curves. Besides, percentage differences (%D) were calculated to estimate the differences and their statistical significance using the Wilcoxon test. Results. The population of boys and girls in San Rafael showed higher weight and BMI (%D ≈ 7% and 9%, respectively) percentiles, and lower height (%D ≈ 0.8%) values than WHO reference (p < 0.05). Conclusion. The differences found warn about the use of the WHO reference in the school-aged population of San Rafael since it would overestimate the prevalence of overweight, obesity, and chronic malnutrition and underestimate the prevalence of acute and global malnutrition. This situation highlights the importance of having a local reference resource

Colgajo supraclavicular, revisión de la literatura y serie de casos / Supraclavicular flap, literature review and case series

Los procedimientos reconstructivos en cabeza y cuello son todo un desafío debido a que son áreas expuestas, con gran movimiento, y desempeñan funciones esenciales de la vida como el habla, la alimentación y la respiración. El colgajo supraclavicular es un colgajo locorregional, fasciocutáneo, fino, axial a la arteria supraclavicular, versátil, con baja morbilidad, que se usa ampliamente para cubrir defectos en cuello y sector inferior de la cara ya que proporciona tejido similar al de estas regiones, y técnicamente rápido y sencillo.Se puede usar en asociación con otros colgajos para reconstrucciones complejas. Es un colgajo infrautilizado que es una buena alternativa frente a los colgajos tradicionales musculares regionales y libres. Las principales indicaciones son secuelas de quemaduras como las contracturas esternomentonianas, defectos oncológicos ya sea piel o mucosa oral, faringostomas y fístulas traqueocutáneas. Se mencionan 3 casos clínicos en los cuales se llevó a cabo un colgajo supraclavicular en el Hospital Pasteur, Montevideo, Uruguay.

Reconstructive head and neck procedures are challenging because they are exposed areas, are highly mobile, and perform essential life functions such as speaking, eating, and breathing. The supraclavicular flap is a locoregional, fasciocutaneous, thin flap, axial to the supraclavicular artery, versatile, with low morbidity, which is widely used to cover defects in the neck and lower face since it provides tissue similar to that of these regions, and Technically fast and simple. It can be used in association with other flaps for complex reconstructions. It is an underutilized flap that is a good alternative to traditional regional and free muscle flaps. The main indications are sequelae of burns such as sternomental contractures, oncological defects in the skin or oral mucosa, pharyngostomies and tracheocutaneous fistulas. Three clinical cases are mentioned in which a supraclavicular flap was performed at the Pasteur Hospital, Montevideo, Uruguay

Low Expression of E-Cadherin and Cdh1 Variants Associated with Diffuse Gastric Cancer

ABSTRACT Background Reduced or null expression of E-cadherin protein is a frequent cause of diffuse gastric cancer (DGC). More than 50% of patients with DGC present somatic variants in CDH1 gene. Objectives The objectives of this study were to study E-cadherin expression and identify variants in the CDH1 gene in gastric tumors of patients with DGC. Methods We studied 18 Mexican DGC patients who attended a hospital of the Mexican Social Security Institute; E-cadherin expression was determined by immunohistochemistry, and variants were identified by Sanger sequencing in promoter and coding regions. Predictive analysis was performed using PolyPhen-2 and HOPE software. Results We found that 56% of DGC patients showed reduced expression of E-cadherin. All patients carried CDH1 variants; overall, 12 different CDH1 variants were identified. Predictive analysis revealed that the rs114265540 variant was probably damaging, with a value of 0.985, indicating a functional impact on the E-cadherin protein. Variants rs34939176 and rs33964119 were identified as risk factors for DGC (odds' ratios [OR] = 31.3, 95% CI 6.3-154.0, p < 0.001; OR = 6.1, 95% CI 2.0-19.0, p < 0.001, respectively) given their elevated frequency and by comparing it with those reported for MXL population in the 1000 Genomes Project database. Conclusions In this Mexican population, the percentage of diffuse gastric tumors with reduced expression of E-cadherin was similar to that reported in other populations. All gastric tumors of DGC patients studied had somatic CDH1 gene variants; however, the rs114265540, rs34939176, and rs33964119 variants were importantly related to DGC.

Síndrome de Andersen Tawil en una embarazada con alto riesgo de muerte súbita. Reporte de caso / Andersen Tawil syndrome in a pregnant woman at high risk of sudden death

Resumen ANTECEDENTES: El síndrome de Andersen Tawil es una canalopatía multisistémica genética, muy rara, sin alteración cardiaca estructural, heredada de manera autosómica dominante y causada por mutación en el gen KCNJ2. Este síndrome se caracteriza por una triada de parálisis muscular periódica, cambios en el electrocardiograma y estructurales corporales. El rasgo distintivo es la taquicardia ventricular bidireccional, las contracciones ventriculares prematuras y raramente taquicardia polimórfica tipo torsade de pointes. En la actualidad se carece de guías para el peri y postparto y para la prevención de arritmias. CASO CLÍNICO: Paciente de 21 años, embarazada, con síndrome de Andersen Tawil diagnosticado a esta edad, con base en los antecedentes de síncope de repetición y debilidad en las extremidades desde los 11 años. Recibía tratamiento con un beta-bloqueador y un desfibrilador automático implantable. La ecocardiografía fetal a las 23 y 33 semanas de gestación reportó una comunicación interventricular apical de 1.6 mm. A las 39 semanas de embarazo se practicó una cesárea electiva, con evolución posoperatoria satisfactoria. El estudio molecular dirigido al recién nacido descartó el síndrome de Andersen Tawil congénito. CONCLUSIÓN: En pacientes con síndromes de arritmia congénita, el embarazo puede ser seguro siempre y cuando un grupo de especialistas esté pendiente para tomar decisiones de atención y tratamiento durante todo el proceso del embarazo y puerperio.

Abstract BACKGROUND: Andersen Tawil syndrome is a very rare genetic multisystemic channelopathy without structural cardiac alteration, inherited in an autosomal dominant manner and caused by mutation in the KCNJ2 gene. This syndrome is characterised by a triad of periodic muscle paralysis, electrocardiogram and body structural changes. The hallmark is bidirectional ventricular tachycardia, premature ventricular contractions and rarely polymorphic torsade de pointes tachycardia. Currently there is a lack of guidelines for peri- and postpartum and arrhythmia prevention. CLINICAL CASE: 21-year-old pregnant patient with Andersen-Tawil syndrome diagnosed at this age, based on a history of repeated syncope and weakness in the extremities since the age of 11. She was being treated with a beta-blocker and an implantable cardioverter defibrillator. Fetal echocardiography at 23 and 33 weeks gestation reported an apical ventricular septal defect of 1.6 mm. Elective caesarean section was performed at 39 weeks of pregnancy, with satisfactory postoperative evolution. Molecular study of the newborn ruled out congenital Andersen-Tawil syndrome. CONCLUSION: In patients with congenital arrhythmia syndromes, pregnancy can be safe as long as it is managed by a group of experts to make decisions and optimise care throughout the pregnancy and postpartum period.

Epidermólisis bulosa distrófica recesiva en mujer embarazada. Reporte de caso / Recessive dystrophic epidermolysis bullosa in pregnant women. Case report

Resumen INTRODUCCIÓN: La epidermólisis bulosa engloba a un grupo de enfermedades caracterizadas por una fragilidad extrema de la piel y membranas mucosas, consecuencia de la formación de ampollas posterior a un traumatismo mínimo. Hay tres tipos principales de epidermólisis. Se comunica el caso para hacer notar las implicaciones del cuidado al momento del nacimiento, y las consideraciones anestésicas. CASO CLÍNICO: Paciente de 25 años en su segundo embarazo con epidermólisis bulosa distrófica recesiva. El nacimiento fue electivo mediante cesárea, con anestesia regional. CONCLUSIONES: Debe tenerse especial cuidado durante las intervenciones terapéuticas a fin de evitar la formación de bulas o exacerbar las existentes. Las fuerzas de fricción son más dañinas que las de compresión. La planeación multidisciplinaria es necesaria para un desenlace sin complicaciones.

Abstract BACKGROUND: Epidermolysis bullosa encompasses a group of diseases characterized by extreme fragility of the skin and mucous membranes, resulting in the formation of blisters after minimal trauma; There are three main types of epidermolysis. The case is presented to highlight the implications of care both at the time of birth, as well as anesthetic considerations. CLINICAL CASE: A 25-year-old patient in her second pregnancy with recessive dystrophic epidermolysis bullosa. The birth was elective by caesarean section under regional anesthesia. CONCLUSIONS: Special care must be taken during therapeutic interventions to avoid the formation of bullae or exacerbate those already present. Friction forces are more damaging than compression forces. Multidisciplinary planning is necessary for a smooth outcome.

Introducción: La adecuada nutrición en el embarazo depende no solo de la correcta ingesta de alimentos, sino también de una apropiada administración de vitaminas, minerales y otros nutrientes en forma de suplementos. Objetivo: Describir aspectos relacionados sobre la suplementación con ácido fólico, hierro, yodo, calcio, vitamina B12 y omega-3, durante el embarazo. Método: Se realizó una revisión sistemática entre mayo de 2022 y marzo de 2023 sobre la suplementación con algunas vitaminas y minerales durante el embarazo. Se revisaron bases de datos electrónicas de literatura científica biomédica como: UpToDate, Science Direct, SciELO y PUBMED, LILACS. Se realizó la búsqueda de artículos desde el 2016 hasta 2022. Los términos de búsqueda en las bases de datos fueron: suplementos "Vitaminas", "Micronutrientes", "Minerales", y "Embarazo", en inglés y en español. Resultados: Los requerimientos de vitaminas, minerales y diferentes nutrientes aumentan en el embarazo. Una apropiada alimentación y el consumo de micronutrientes en forma de suplementos son el soporte básico para un adecuado desarrollo de la madre y del feto; por otra parte, una nutrición adecuada reduce el riesgo de malformaciones congénitas, complicaciones obstétricas, fetales y perinatales. No todas las embarazadas necesitan la misma cantidad de suplementos, por lo que es necesario identificar aquellas con mayor riesgo de presentar alguna deficiencia. Conclusiones: La suplementación de vitaminas, minerales y otros micronutrientes durante el embarazo es muy importante para disminuir el riesgo de complicaciones obstétricas y anomalías fetales y perinatales.

Introduction: Adequate nutrition in pregnancy depends not only on a healthy diet, but also on the most effective way of taking vitamins, minerals and other nutrient supplementation. Objective: To describe aspects related to supplementation with folic acid, iron, iodine, calcium, vitamin B12 and omega-3 in pregnancy. Method: A systematic review was conducted between May 2022 and March 2023, concerning supplementation intake of vitamins and minerals in pregnancy. Electronic databases of biomedical scientific literature were reviewed such as: UpToDate, Science Direct, SciELO and PUBMED, LILACS. Searching was on articles published from 2016 to 2022. The key terms for searching in databases were as follow: supplements "Vitamins", "Micronutrients", "Minerals", and "Pregnancy", in English and Spanish. Results: A vitamin, minerals and different nutrients intake requirements has increased in pregnancy. An appropriate diet and the consumption of micronutrients in the form of supplements are the basic support for an adequate health status of the mother and the development the fetus; on the other hand, an adequate nutrition reduces the risk of congenital malformations, obstetric, fetal and perinatal complications. Not all pregnant women need the same amount of supplements, so it is necessary to identify those with a highest risk of presenting deficiency. Conclusions: Supplementation of vitamins, minerals and other micronutrients in pregnancy is very important to reduce the risk of obstetric complications and fetal or perinatal anomalies.

Se utilizó muestreo no probabilístico intencional. La muestra fue de 45 mujeres con riesgo preconcepcional. La investigación se realizó en 3 etapas: diagnóstica, intervención y evaluación. La información se recogió en una encuesta semiestructurada que se aplicó antes y después de la intervención. Las variables fueron: métodos para planificar el embarazo, edad óptima para el embarazo, antecedentes obstétricos desfavorables, importancia del consumo de ácido fólico antes del embarazo y conocimiento general sobre el tema. Se determinó el test de McNemar para el análisis estadístico e índice de kappa para determinar efectividad de la intervención. Resultados: Antes de la intervención se diagnosticó nivel de conocimiento inadecuado sobre los métodos para planificar el embarazo (42 %), edad óptima para el embarazo (40 %) y en los antecedentes obstétricos (36 %). Posterior a la intervención el nivel de conocimiento adecuado fue significativo (p<0.05) en todas las variables. El índice kappa arrojó acuerdo considerable. Conclusiones: La intervención educativa fue efectiva.

Background: Reproductive health is present during women and men's life cycle, so family planning, knowledge and management of reproductive risk play a significant role. Objective: To evaluate the effectiveness of a knowledge intervention in fertile age women with preconception risk, at "La Colonia" clinic, in "Rafael Teope Fonseca" Polyclinic, "El Salvador", Guantánamo, from September 2017 to April 2019. Methodology: A quasi-experimental study was conducted, of educational intervention type on preconception risk, with formerly and subsequently designs. The universe was 65 women of fertile age. Intentional non-probabilistic sampling was used. The sample was 45 women with preconception risk. The research was conducted in 3 stages: diagnosis, intervention and evaluation. The information was collected in a semi-structured survey applied before and after the intervention. The variables were: methods for planning pregnancy, optimal age for pregnancy, unfavorable obstetric history, importance of folic acid intake before pregnancy, and general knowledge on the subject. The McNemar test was determined for the statistical analysis and the Kappa index to determine the effectiveness of the intervention.

Congenital hearing loss: a literature review of the genetic etiology in a Mexican population / Pérdida auditiva congénita: revisión de la etiología genética en la población mexicana

Abstract Hearing loss is the most frequent sensory disorder, with an incidence of 1:1500 live newborns. In more than 50% of patients, it is associated with a genetic cause, while in up to 30% of cases, it is related to syndromic entities. We performed a literature review of studies on congenital hearing loss of genetic origin in the Mexican population. We identified eight reports that showed that the pathogenic variants most frequently associated with hearing loss are related to the GJB2 gene, although in a low percentage (3%). Other mutations were identified in the GJB6, SLC26A4, or CHD23 genes. On this basis, a possible diagnostic strategy in Mexican patients with hearing loss is to consider an initial screening of these three genes. If these genes were negative for pathogenic variants, the following steps would be to consider second-generation sequencing analysis focused on panels of genes associated with hearing loss, isolated or syndromic, and if necessary, to perform exome or whole-genome analysis. Establishing an etiologic cause is critical in clinically evaluating patients with congenital hearing loss and their families. It can help determine rehabilitation strategies, such as hearing aids or cochlear implants and provide information on disease progression and genetic counseling in this population.

Resumen La pérdida auditiva es la alteración sensorial más frecuente, con una incidencia de 1:1500 recién nacidos vivos. En más del 50% de los pacientes se asocia con una causa genética, mientras que en más del 30% de los casos se asocia con entidades sindrómicas. Se llevó a cabo una revisión de la literatura de las investigaciones sobre la pérdida auditiva congénita de origen genético en la población mexicana. Se identificaron ocho reportes en los que se demostró que las variantes patogénicas más frecuentemente asociadas con pérdida auditiva se encuentran en el gen GJB2, aunque en un porcentaje bajo (3%). Se identificaron otras mutaciones en los genes GJB6, SLC26A4 o CHD23. Con base en esta información, una posible estrategia diagnóstica en pacientes mexicanos con pérdida auditiva es considerar un primer paso en el tamiz diagnóstico con los tres genes mencionados. Si estos genes fueran negativos para variantes patogénicas, el siguiente paso sería considerar el análisis por secuenciación de segunda generación enfocado en paneles de genes asociados con pérdida auditiva, tanto aislada como sindrómica, y en caso necesario, realizar el análisis del exoma o del genoma completo. Establecer una causa etiológica es un componente crítico en la evaluación clínica de los pacientes con pérdida auditiva congénita, ya que puede ayudar a determinar las estrategias de manejo y rehabilitación, como el uso de auxiliares auditivos o implantes cocleares, proporcionar información sobre la progresión de la enfermedad y dar asesoramiento genético en esta población.

Lipomas gigantes da mão, série de casos / Giant lipomas of the hand, case series

Introdução: Os lipomas são esporádicos na mão e representam menos de 5% dos tumores de partes moles nesta topografia. Os lipomas gigantes, ainda menos comuns, são definidos por terem um diâmetro maior do que 5cm. Métodos: Executamos uma análise retrospectiva dos casos de pacientes com lipomas gigantes de mão, atendidos no período de 2017-2020, no Hospital Pasteur e Hospital de Clínicas, em Montevidéu, Uruguai. Resultados: Obtivemos quatro pacientes no período estudado. A idade de apresentação foi entre 51 e 62 anos (média de 57 anos). Três dos lipomas eram intramusculares profundos e um era superficial aos músculos regionais. O maior possuía eixo mais extenso de 70mm. Todos eram sintomáticos. A ressecção marginal foi realizada em todos eles, e o pós-operatório transcorreu sem intercorrências ou recorrências. A histopatologia confirmou lipoma típico em três casos, e lipoma com metaplasia óssea no outro. Conclusão: Lipomas gigantes de mão se apresentam como tumores indolores e de crescimento lento, que podem ser sintomáticos ao comprimir estruturas adjacentes. A ressonância magnética é o estudo de imagem escolhido para estes casos. O tratamento aplicável é a ressecção cirúrgica marginal e a recorrência é pouco comum.

Introduction: Lipomas are sporadic in hand and represent less than 5% of soft tissue tumors in this topography. Giant lipomas, even less common, are defined as having a diameter greater than 5 cm. Methods: We performed a retrospective analysis of the cases of patients with giant lipomas of the hand seen in the period 2017-2020, at Hospital Pasteur and Hospital de Clínicas, in Montevideo, Uruguay. Results: We obtained four patients during the study period. The age of presentation was between 51 and 62 years (mean 57 years). Three lipomas were deep intramuscular, and one was superficial to the regional muscles. The largest had a longer axle of 70mm. All were symptomatic. Marginal resection was performed in all of them, and the postoperative period was uneventful or recurrent. Histopathology confirmed typical lipoma in three cases and lipoma with bone metaplasia in the other. Conclusion: Giant lipomas of the hand present as painless, slow-growing tumors that may be symptomatic when compressing adjacent structures. Magnetic resonance imaging is the imaging study of choice for these cases. The applicable treatment is marginal surgical resection, and recurrence is uncommon.

Referencias de índice de masa corporal. Precisión diagnóstica con área grasa braquial en escolares argentinos / Body mass index references. Diagnostic accuracy with the upper-arm fat area in Argentine schoolchildren

El índice de masa corporal (IMC) es una eficaz herramienta para detectar la sobrecarga ponderal en niños y adolescentes, asociado a la adiposidad corporal. Objetivo. Analizar la concordancia, sensibilidad y especificidad de tres referencias internacionales de IMC/edad (OMS, IOTF y CDC) para diagnosticar el exceso ponderal y conocer su precisión diagnóstica para identificar el exceso de adiposidad con relación al área grasa braquial (AGB) en población infanto juvenil de Argentina. Materiales y métodos. Se realizó un estudio multicéntrico, descriptivo-comparativo y transversal entre 2003 y 2008, en 22.658 niños y adolescentes argentinos de 4 a 13 años de edad. A partir del peso, talla, circunferencia del brazo y pliegue tricipital, se calcularon IMC y AGB. Se analizó la concordancia, sensibilidad y especificidad de referencias de IMC/edad (OMS, CDC, IOTF) y la precisión diagnóstica (curvas ROC) para identificar exceso de adiposidad, a partir del AGB, así como el punto de corte óptimo (PCO). Resultados. Las tres referencias tuvieron buena concordancia. La mayor sensibilidad correspondió a OMS y la mayor especificidad a IOTF. El área bajo la curva (ABC) fue mayor en Z-IMC/IOTF en varones y en Z-IMC/OMS en mujeres. Los PCO mostraron discrepancias, siendo mayores con OMS. Conclusión. Las tres referencias muestran similar precisión diagnóstica para detectar alta reserva calórica, con puntos de corte óptimo para las puntuaciones Z-IMC menores a 2 Z scores. Esto resulta relevante para la identificación de exceso de adiposidad en poblaciones, en relación con la implementación de políticas públicas de prevención de enfermedades crónicas no transmisibles(AU)

The body mass index (BMI) is an effective tool to detect weight overload in children and adolescents, associated with body adiposity. Objective. To analyze the concordance, sensitivity and specificity of three international BMI/age references (WHO, IOTF and CDC) to diagnose excess weight and to know their diagnostic accuracy to identify excess adiposity in relation to the brachial fat area (BFA) in Argentine child-youth population. Materials and methods. A multicenter, descriptive- comparative and cross-sectional study was carried out between 2003 and 2008 in 22.658 Argentine children and adolescents between aged 4 to 13 years. From the weight, height, arm circumference and tricipital fold, BMI and BFA were calculated. The concordance, sensitivity, and specificity of BMI / age references (WHO, IOTF, CDC,) were analyzed and the diagnostic precision (ROC curves) to identify excess adiposity, from the BFA, as well as the optimal cut-off point (OCP). Results. The three references had good agreement, the highest sensitivity corresponded to WHO and the highest specificity to IOTF. The area under the curve (AUC) was greater in Z-BMI/IOTF in men and in Z-BMI/WHO in women. The OCPs showed discrepancies, being higher with WHO. Conclusion. The three references show similar diagnostic accuracy to detect high caloric reserve, but with cut-off points for Z-BMI scores less than 2 Z scores. This is relevant for the identification of excess adiposity in populations in relation to the implementation of public policies for the prevention of chronic non-communicable diseases(AU)

Evaluación de la función renal para la detección y seguimiento de la enfermedad renal crónica. Documento multidisciplinario de consenso 2021. Especial atención sobre situaciones clínicas específicas / Evaluation of renal function for the detection and follow-up of chronic kidney disease. Multidisciplinaryconsensus document 2021. Special attention to specific clinical situations

Resumen El filtrado glomerular (FG) se considera el mejor índice para evaluar la función renal en la práctica clínica. Recientemente, ha ganado popularidad la utilización de ecuaciones que estiman el FG, en distintas poblaciones, a partir de los niveles séricos de algunos biomarcadores. Sin embargo, no todas las fórmulas han sido validadas en los diversos escenarios clínicos probables. Las sociedades participantes: Sociedad Argentina de Nefrología, Asociación Bioquímica Argentina, Fundación Bioquímica Argentina y Confederación Unificada Bioquímica de la República Argentina, integradas por nefrólogos y bioquímicos, realizaron un consenso actualizado sobre la utilización del FG como herramienta de detección de la enfermedad renal crónica (ERC) en la Argentina. Se analizó la bibliografía existente y, teniendo en cuenta aspectos de nuestra realidad sanitaria, se establecieron sugerencias para su utilización. Se actualizaron las indicaciones del uso del FG medido. En sucesivos capítulos se puso foco en distintos estados del FG en diversas poblaciones y situaciones. En los estados de reducción del FG, se mencionaron tanto los fisiológicos propios del envejecimiento, como los determinados por situaciones patológicas, por ejemplo, el observado en la ERC avanzada o el determinado en aquellos pacientes que recibieron un trasplante renal. Se revisaron, por otro lado, las situaciones de incremento del FG, como las observadas en el embarazo o en la obesidad. Se refirieron, asimismo, las limitaciones de la estimación del FG, se reconoció su valor en situaciones de la práctica clínica habitual, o en contextos epidemiológicos definidos y se sugirieron las ecuaciones más adecuadas para su utilización en cada caso.

Abstract The glomerular filtration rate (GFR) is considered the best index to assess the renal function in clinical practice. Recently, the use of equations to estimate GFR in different populations, based on the serum levels of some biomarkers, has gained popularity. However, not all the equations have been validated in the various likely clinical scenarios. Thus, the participating societies, i.e. the Argentine Society of Nephrology, the Argentine Association of Biochemistry, the Argentine Foundation of Biochemistry, and the Unified Confederation of Biochemistry of Argentina, composed of nephrologists and biochemists, have established an updated consensus on the use of the GFR as a tool for the detection of chronic kidney disease (CKD) in Argentina. The consensus was established on the basis of the analysis of the existing literature and taking into account aspects of the health situation in Argentina. Suggestions for the use of the GFR were made, and the indications for its use were updated. The successive chapters of the consensus consider different values of the GFR in different populations and situations. The different situations considered and reviewed include cases of a decrease in the GFR, such as the physiological one related to aging and that related to pathological situations, as observed in advanced CKD or in patients who have received a kidney transplant, as well as cases of an increase in the GRF, such as that observed in pregnancy or obesity. The consensus also mentions the advantages and limitations of the estimation of the GFR in situations of usual clinical practice or in specific epidemiological contexts, and the most appropriate equations for its use in each case is suggested.

Resumo A filtração glomerular (FG) é considerada o melhor índice para avaliar a função renal na prática clínica. Recentemente, a utilização de equações que calculam a FG, em diferentes populações, ganhou popularidade a partir dos níveis séricos de alguns biomarcadores. Entretanto, nem todas as fórmulas têm sido validadas nos diversos cenários clínicos prováveis. As sociedades participantes: Sociedade Argentina de Nefrologia, Associação Bioquímica Argentina, Fundação Bioquímica Argentina e Confederação Unificada Bioquímica da República Argentina, integradas por nefrologistas e bioquímicos, realizaram um consenso atualizado sobre a utilização da FG, como ferramenta de detecção da doença renal crônica (DRC) na Argentina. Foi analisada a bibliografia existente e, considerando aspectos da nossa realidade sanitária, foram estabelecidas sugestões para sua utilização. Foram atualizadas as indicações do uso da FG medida. Em sucessivos capítulos se colocou o foco em diferentes estados da FG em populações e situações diversas. Nos estados de redução da FG, foram mencionados tanto os fisiológicos próprios do envelhecimento, quanto os determinados por situações patológicas, por exemplo, aquele observado na DRC avançada ou o determinado naqueles pacientes que receberam um transplante renal. Por outra parte, foram revistas as situações de aumento da FG como as observadas na gravidez ou na obesidade. Foram referidas, também, as limitações da estimativa da FG, foi reconhecido o seu valor em situações da prática clínica habitual, ou em contextos epidemiológicos definidos e se sugeriram equações mais adequadas para sua utilização em cada caso.
