Competencias narrativas escritas en niños con trastornos del desarrollo / Narrative in children with developmental disorders

RESUMEN INTRODUCCIÓN: Los aspectos narrativos del lenguaje constituyen una competencia en el desarrollo funcional de la comunicación, la cual predice el desempeño académico de los niños. En este trabajo se estudia la narrativa en niños con trastornos del desarrollo, a fin de hacer diagnósticos precoces y adoptar mejores estrategias terapéuticas. MATERIAL Y MÉTODO: Estudio controlado analítico de corte transversal. Se incluyen sujetos de 9 a 17 años, evaluados con la prueba de teoría de la mente (TOM) de Sally y Anne, quienes luego deben narrar la historia de la prueba. Se evaluó el número total de palabras (TP), la cantidad total de oraciones (TO), el promedio de palabras por oración (PPO), la sintaxis (S) y la capacidad expresar la idea central del relato (ICR). RESULTADOS: Participaron 61 sujetos. El grupo 1 o control con 24, el grupo 2 con 37 sujetos (con diagnóstico de trastorno por déficit de atención (TDA), trastorno de la lectoescritura (TLE), trastorno del espectro autista (TEA) y discapacidad intelectual (DI)). En teoría de la mente respondieron correctamente 18 participantes del grupo 1, 7 participantes con TDA, 4 de los TLE, 5 sujetos con DI y 3 sujetos con TEA. Los sujetos del grupo 2 presentaron distintos grados de dificultades narrativas según el trastorno. A mayor edad utilizaron mayor cantidad de palabras, sin distinción por sexo. CONCLUSIÓN: Es importante estudiar los aspectos narrativos del lenguaje en pediatría puesto que las habilidades requeridas incluyen aspectos estructurales del lenguaje y habilidades cognitivas que es necesario tener en cuenta para definir estrategias terapéuticas más precisas y acordes a las necesidades de este grupo de pacientes.

ABSTRACT INTRODUCTION: Narrative is a competence in the functional development of communication that predicts academic performance in children. We studied narrative in children with developmental disorders in order to develop better therapeutic strategies. METHODS: Cross-sectional analytical controlled study. We included subjects age 9 to 17 years old, evaluated with the Mind Theory Test (TOM) of Sally and Anne in which they have to repeat a story. We evaluated total number of words (TP), total number of sentences (TO), average words per sentence (PPO), syntax (S) and ability to express the central idea of the story (ICR). RESULTS: We included 61 subjects in two groups. Group 1 or control with 24, Group 2 with 37 subjects (with a diagnosis of attention deficit disorder (ADD), literacy disorder (TLE), autistic spectrum disorder (ASD), intellectual disability (ID)). TOM 3 was correctly answered by 18 subjects of Group 1, 7 of ADD, 4 of the TLE, 5 of the ID and 3 participants with TEA. The Group 2 presented different degrees of narrative difficulties. All children said more words when they grew up without distinction by gender. DISCUSSION: Children with developmental disorders present a lower performance in narrative aspects depending of the disorder, which allows to carry out therapeutic strategies according to their needs.

IgA Deficiency Is Not Systematically Ruled Out in Patients Undergoing Celiac Disease Testing.

BACKGROUND: Guidelines for celiac disease (CD) testing recommend total serum IgA determination alongside anti-transglutaminase IgA antibodies. It is not well known if lack of serum IgA determination is a common finding in clinical practice. AIM: To determine the prevalence of lack of serum IgA determination among patients screened for celiac disease. MATERIALS AND METHODS: We identified all subjects who underwent serum anti-transglutaminase IgA and/or other CD-related antibodies determination at a single teaching hospital in Buenos Aires from October 2019 to February 2020. Medical records were reviewed to select adult patients who were tested for celiac disease. The primary outcome was the proportion of patients with inadequate testing for celiac disease due to lack of serum IgA determination. We retrieved the following variables from each patient's record: age, gender, body mass index, symptoms present at screening, first-grade family history of CD, history of type-1 diabetes mellitus, autoimmune hypothyroidism, Down's syndrome. RESULTS: Overall, 1122 patients were included for analysis. Lack of serum IgA determination prevalence was 20.49%. Among patients who did have serum IgA determination, the prevalence of IgA deficiency was 5.16%. The following variables were independently associated with a significantly increased odds of serum IgA determination: diarrhea [OR 1.55 (1.01-2.34)] and abdominal pain [OR 2.28 (1.44-3.63)]; higher body mass index [OR 0.91 (0.85-0.98)], osteoporosis [OR 0.49 (0.28-0.89)], hypothyroidism [OR 0.18 (0.07-0.45)], arthralgia/arthritis [OR 0.47 (0.27-0.85)], or testing by endocrinologist [OR 0.46 (0.23-0.91)] and gynecologist [OR 0.14 (0.06-0.31)] were inversely associated. CONCLUSION: IgA deficiency is not systematically ruled out in a relatively high proportion of patients undergoing serological screening of celiac disease.

[Endoscopic ultrasound-guided hepaticogastrostomy for treatment of malignant biliary obstruction in patient with Roux-en-Y gastrectomy]. / Hepático-gastrostomía guiada por eco endoscopia en obstrucción biliar maligna y gastrectomía subtotal con reconstrucción en Y de Roux.

Endoscopic retrograde cholangiography with biliary stenting is the generally recognized optimal treatment of malignant biliary obstruction. This procedure, though, is challenging in patients with surgically altered anatomy. Endoscopic ultrasound (EUS) enables tissue sampling by means of fine-needle aspiration and also represents an alternative recourse for biliary drainage in preference to a percutaneous approach. We aimed to report a case in which EUS enabled a definitive diagnosis of the recurrence of oncologic disease and the relief of biliary obstruction in a patient with a surgically altered anatomy.

RESUMEN La colangiopancreatografía retrógrada endoscópica (CPRE) representa el tratamiento de primera línea para el drenaje biliar en pacientes con obstrucción biliar maligna avanzada. Sin embargo, este procedimiento representa un desafío en pacientes con anatomía alterada quirúrgicamente. El ultrasonido endoscópico (USE) permite la toma de muestras de tejido mediante punción aspiración con aguja fina y también representa una alternativa de drenaje biliar al abordaje percutáneo o quirúrgico. Nuestro objetivo es comunicar un caso en el que la ecoendoscopia permitió el diagnóstico definitivo de la recurrencia de la enfermedad oncológica de base y el alivio de la obstrucción biliar en un paciente con anatomía alterada quirúrgicamente.

INCREASED RISK OF SYNCHRONOUS COLORECTAL LESIONS IN PATIENTS REFERRED FOR ENDOSCOPIC MUCOSAL RESECTION OF LATERAL SPREADING TUMORS.

BACKGROUND: Endoscopic mucosal resection is one of the most frequent therapeutic alternatives for large colorectal lateral spreading tumors. There are few data on the prevalence of synchronous lesions on these patients. OBJECTIVE: To describe the prevalence of synchronous colorectal lesions in patients referred for endoscopic mucosal resection of lateral spreading tumors >20 mm. METHODS: We reviewed the endoscopic database of our Department and identified adult patients who were referred for the resection of a colorectal lateral spreading tumor >20 mm and had a diagnostic colonoscopy performed up to six months before. The proportion of patients with at least one synchronous lesion was estimated. The following features were compared between patients with and without synchronous lesions: age, gender, bowel preparation quality and cecal intubation on index colonoscopy and therapeutic colonoscopy, serrated adenoma as index lesion. RESULTS: From December 2016 to November 2017, we identified 70 patients who fulfilled inclusion criteria. Median size of lesions was 25 mm (20-45). Eighty percent were located in the right colon and 35.71% were serrated adenomas. Synchronous lesion rate was 38.57%. Bowel preparation quality was similar in both groups when comparing both index and therapeutic colonoscopies. Patients with synchronous lesions had a higher proportion of serrated adenoma as index lesion than patients without synchronous lesions [51.85% vs 25.58%, OR 3.13 (1.13-8.68), P=0.03]. CONCLUSION: We found a high prevalence of synchronous lesions among patients with a large colorectal lateral spreading tumor. This risk seems to be increased if index lesions are serrated adenomas.

DESCRITORES CONTEXTO: A ressecção endoscópica de mucosa é uma das alternativas terapêuticas frequentes para grandes tumores colorretais de propagação lateral. Há poucos dados sobre a prevalência de lesões síncronas nesses pacientes. OBJETIVO: Descrever a prevalência de lesões colorretais síncronas em pacientes encaminhados para ressecção endoscópica da mucosa de tumores de disseminação lateral >20 mm. MÉTODOS: Realizou-se a revisão de banco de dados endoscópicos de nosso departamento e foram identificados pacientes adultos encaminhados para a ressecção de um tumor colorretal com propagação lateral >20 mm e que tiveram colonoscopia diagnóstica realizada até seis meses antes. Estimou-se a proporção de pacientes com pelo menos uma lesão síncrona. As seguintes características foram comparadas entre pacientes com e sem lesões síncronas: idade, sexo, qualidade da preparação intestinal e intubação cecal pelo índice de colonoscopia e adenoma serrilhado como lesão índice. RESULTADOS: De dezembro de 2016 a novembro de 2017, identificamos 70 pacientes que preencheram os critérios de inclusão. O tamanho mediano das lesões foi de 25 mm (20-45). Foram 80% situados no cólon direito e 35,71% eram adenomas serrilhados. A taxa de lesão síncrona foi de 38,57%. A qualidade da preparação intestinal foi semelhante em ambos os grupos comparando-se os índices e colonoscopia terapêutica. Pacientes com lesões síncronas apresentaram maior proporção de adenoma serrilhado como lesão índice do que pacientes sem lesões síncronas [51,85% vs 25,58%, or 3,13 (1,13-8,68), P=0,03]. CONCLUSÃO: Encontramos alta prevalência de lesões síncronas entre pacientes com grande tumor de propagação lateral colorretal. Este risco parece ser aumentado se as lesões índice forem adenomas serrilhados.
