Variability in Definitions and Criteria of Extrauterine Growth Restriction and Its Association with Neurodevelopmental Outcomes in Preterm Infants: A Narrative Review.

Extrauterine growth restriction (EUGR) has been used in the literature and clinical practice to describe inadequate growth in preterm infants. Significant variability is seen in the criteria for EUGR, with no standard definition reached to date. Moreover, no consensus on the optimal timing for assessment or the ideal growth monitoring tool has been achieved, and an ongoing debate persists on the appropriate terminology to express poor postnatal growth. To ensure an adequate understanding of growth and early intervention in preterm infants at higher risk, it is critical to relate the diagnostic criteria of EUGR to the ability to predict adverse outcomes, such as neurodevelopmental outcomes. This narrative review was conducted to present evidence that evaluates neurodevelopmental outcomes in preterm infants with EUGR, comparing separately the different definitions of this concept by weight (cross-sectional, longitudinal and "true" EUGR). In this article, we highlight the challenges of comparing various published studies on the subject, even when subclassifying by the definition of EUGR, due to the significant variability on the criteria used for each definition and for the evaluation of neurodevelopmental outcomes in different papers. This heterogeneity compromises the obtention of a single firm conclusion on the relation between different definitions of EUGR and adverse neurodevelopmental outcomes.

Coronary Bypass in an Adolescent With Systemic Lupus Erythematosus and Acute Coronary Syndrome.

A 12-year-old female with active pediatric juvenile systemic lupus erythematosus presented to the emergency department because of episodes of oppressive central thoracic pain associated with pallor, sweating, and muscle weakness that persisted for >30 minutes. During the last episode, the electrocardiogram revealed alterations in cardiac repolarization coincident with progressive troponin T elevation. An angio computed tomography revealed a 20 mm long complete segmental obstruction of the proximal anterior descending artery that was confirmed by angiography. Because this extensive occlusion did not permit a noninvasive procedure, an off-pump coronary bypass of the internal mammary artery to the anterior descending artery was performed without complication. Six months after the procedure, myocardial function was good. To our knowledge, this is the first case report of an adolescent girl with acute coronary syndrome complicating juvenile systemic lupus erythematosus that was treated with a surgical procedure.

Lyme borreliosis in pediatric population: Clinical, diagnostic and therapeutic features.

INTRODUCTION: Lyme borreliosis (LB) in the paediatric population is an understudied entity with certain peculiarities. The objective of this study is to describe the characteristics of paediatric patients with LB, and their diagnostic and therapeutic processes. METHODS: Descriptive and retrospective study in patients up to 14 years old with suspected or confirmed LB between 2015 and 2021. RESULTS: A total of 21 patients were studied: 18 with confirmed LB (50% women; median age 6.4 years old) and 3 false positive of the serology. Clinical features in the 18 patients with LB were: neurological (3, neck stiffness; 6, facial nerve palsy), dermatological (6, erythema migratory), articular (1), and non-specific manifestations (5). Serological diagnosis was confirmatory in 83.3% of cases. A total of 94.4% patients received antimicrobial treatment (median duration, 21 days). All recovered with resolution of symptoms. CONCLUSIONS: LB diagnosis is difficult in the paediatric population and presents clinical and therapeutic peculiarities, with favourable prognosis.

Borreliosis de Lyme en población pediátrica: peculiaridades clínicas, diagnósticas y terapéuticas / Lyme borreliosis in pediatric population: Clinical, diagnostic and therapeutic features

Introducción: La borreliosis de Lyme (BL) es una entidad poco estudiada en pediatría, pero con ciertas peculiaridades. El objetivo de este estudio es conocer las características de los pacientes pediátricos con sospecha y/o confirmación de BL. Métodos: Estudio descriptivo y retrospectivo en menores de 14 años con diagnóstico clínico y/o serológico, sospechoso o confirmado, de BL entre 2015 y 2021. Resultados: Se estudiaron 21 pacientes: 18 con diagnóstico final de BL (50% mujeres; mediana de edad 6,4 años) y 3 falsos positivos. En los casos de BL, las manifestaciones clínicas presentadas fueron: neurológicas (3, meningitis; 6, parálisis facial), dermatológicas (6, eritema migratorio), articulares (uno) e inespecíficas (2). El diagnóstico serológico fue confirmatorio en el 83,3% de los casos. El 94,4% recibió antibioterapia (mediana de duración 21 días) y la evolución fue satisfactoria en todos los casos. Conclusiones: El diagnóstico de la BL es difícil en la población pediátrica y presenta peculiaridades clínicas y terapéuticas, pero el pronóstico es favorable.(AU)

Descripción clínica y epidemiológica de un brote grave de salmonelosis en una escuela infantil urbana / Clinical and epidemiologic description of a severe outbreak of Salmonellosis in an urban nursery school

Objetivos. Se describe clínica y epidemiológicamente unbrote de infección gastrointestinal por Salmonella entéricaser. (serotipo) Enteritidis, en una escuela infantil urbana, queconllevó elevada morbilidad e importante alarma social. La comunicación inmediata, así como el estudio adecuado del brote,en ambas vertientes, permitieron identificar el patógeno y establecer medidas de control en un plazo razonable de tiempo.Se discuten aspectos controvertidos como la indicación de antibioterapia o el momento de cierre del centro.Material y métodos. Se recogió retrospectivamente información clínica, analítica y epidemiológica, y se revisó la metodología y resultados del estudio del brote.Resultados. 57 niños (3-45 meses) de 92 asistentes al centro, fueron afectados y tuvieron confirmación microbiológica.Diarrea y fiebre fueron los principales síntomas. 74% acudieronal hospital, y 37% ingresaron, (estancia media 3,3 días). Fueronfactores asociados al ingreso: deshidratación, elevación significativa de reactantes de fase aguda y coagulopatía. 12 recibieroncefotaxima parenteral. Se registraron 2 complicaciones: 1 bacteriemia y 1 reingreso. La sospecha inicial del origen del brotefueron los alimentos, pero el análisis de las muestras testigofue negativo. 5 trabajadores fueron positivos (2 sintomáticos).Vigilancia Epidemiológica concluyó que el origen probable delbrote fue un portador asintomático y la manipulación incorrectade pañales. El centro permaneció cerrado 8 días. Se realizaronmedidas de limpieza y desinfección, instrucción sobre cambio depañales y seguimiento de portadores.Conclusiones. La agrupación en tiempo y espacio de casos debe ser notificada inmediatamente para el control precozdel brote. Los niños pueden presentar formas graves de gastroenteritis por Salmonella. (AU)

Objectives. We describe clinically and epidemiologically anoutbreak of gastrointestinal infection by Salmonella entericaser. (serotype) Enteritidis in an urban infant school, which ledto high morbidity and significant social alarm. The immediatecommunication, as well as the adequate study of the outbreak, inboth aspects, allowed identifying the pathogen and establishingcontrol measures in a reasonable period of time. Controversialaspects such as the indication of antibiotherapy or the momentof closing the center are discussed.Methods. We retrospectively collected clinical, analyticaland epidemiological information and we reviewed themethodology of the outbreak study and its results.Results. A total of 57 children (3-45 months), wereaffected and had microbiological confirmation. Diarrhea andfever were the main symptoms. 74% went to the hospital and37% were admitted (mean stay 3.3 days). Factors associatedwith admission were: dehydration, significant elevation ofacute phase reactants and coagulopathy. Twelve patientsreceived parenteral cefotaxime. There were 2 complications:1 bacteremia and 1 readmission. The initial suspicion ofthe origin of the outbreak was food, but the analysis of thecontrol samples was negative. Five workers were positive (2symptomatic). Epidemiologic Surveillance concluded that theprobable origin of the outbreak was an asymptomatic carrierand improper diapers handling. The center was closed for 8days. Cleaning and disinfection measures were carried out, aswell as instruction on diaper changing, and the carriers werefollowedConclusions. Clustering in time and space of cases shouldbe reported immediately for early control of the outbreak.Children may present severe forms of Salmonella gastroenteritis (AU)
