La prematuridad tiene una alta tasa de incidencia en los países desarrollados, representando el 75% de la mortalidad perinatal. Aunque los avances prenatales y perinatales de las últimas décadas han permitido reducir su prevalencia, en consecuencia, se ha hecho evidente la presencia de morbilidades y comorbilidades en el desarrollo de estos infantes.El propósito de esta investigación, de carácter prospectivo y longitudinal, es analizar los componentes del lenguaje (morfología, sintaxis, semántica y pragmática) de 29 menores, nacidos prematuros extremos, en el Hospital Universitario La Paz de Madrid y que actualmente están en edad escolar obligatoria, para identificar la presencia de posibles dificultades en el lenguaje. Todos los participantes estaban matriculados en Educación Primaria y los componentes del lenguaje se evaluaron a través de la batería BLOC-Screening.Los resultados evidencian que existen comorbilidades en el componente morfológico en los siguientes elementos: formas irregulares de pasado, formas irregulares de futuro, reflexivos ; en el componente semántico (locativos, cuantificadores, modificadores de tiempo y sucesión ) y en sintaxis (voz pasiva, oraciones comparativas, oraciones subordinadas de causa y condición, y en las temporales [después/antes] ), obteniéndose mejores resultados en el componente pragmático, excepto en aquellas acciones que requieren expresar demandas y solicitar información específica.Por tanto, el perfil obtenido en lenguaje de los prematuros extremos sugiere la necesidad de intervención logopédica y conlleva la necesidad de hacer propuestas de intervención didáctica en la escuela que mejoren sus habilidades lingüísticas desde un enfoque comunicativo.(AU)
Prematurity has a high incidence rate in developed countries, accounting for 75% of perinatal mortality. Although pre- and perinatal advances in recent decades have reduced its prevalence, consequently, the presence of morbidities and comorbidities in the development of these infants has become evident.The purpose of this prospective and longitudinal research is to analyze the language components (morphology, syntax, semantics and pragmatics) of 29 minors, born extremely premature, at the Hospital Universitario La Paz in Madrid and who are currently of compulsory school age, in order to identify the presence of possible language difficulties. All the participants were enrolled in Primary Education and the language components were assessed using the BLOC-Screening battery.The results show that there are comorbidities in the morphological component in the following elements: irregular forms of the past, irregular forms of the future, reflexive ; in the semantic component (locatives, quantifiers, modifiers of time and succession ) and in syntax (passive voice, comparative clauses, subordinate clauses of cause and condition, and in the temporal ones [after/before] ), obtaining better results in the pragmatic component, except in those actions that require expressing demands and requesting specific information.Therefore, the profile obtained in the language of extremely premature infants suggests the need for speech therapy intervention and entails the need to make proposals for educational intervention at school that improve their language skills from a communicative approach.(AU)

El Programa de cribado o detección precoz del hipotiroidismo congénito es uno de los mayores avances logrados en Pediatría. Las hormonas tiroideas son imprescindibles para el desarrollo y la maduración cerebral, que continúan en la etapa neonatal. Las alteraciones de la función tiroidea en niños prematuros y con bajo peso en los primeros meses de vida origina lesiones irreversibles en el sistema nervioso central y es una de las causas más frecuentes y evitables de retraso mental. El diagnóstico en el periodo neonatal es difícil, por lo que requiere estudio analítico para poder efectuar el tratamiento adecuado.La relevancia de este problema justifica su difusión a todas las áreas de Pediatría. El objetivo principal, evitar el daño cerebral en estos pacientes. Otros aspectos para optimizar el desarrollo adecuado de estos niños con todos los controles periódicos necesarios y lograr la inclusión del diagnóstico de las alteraciones tiroideas durante la estancia en unidades neonatales y en los primeros meses de vida precisan implementar los recursos de los centros sanitarios y continuar avanzando según los conocimientos actuales.En el presente documento nos centraremos en el cribado de los recién nacidos pretérmino (< 32 semanas de gestación) o con muy bajo peso para la edad gestacional (1.500-1.000 g muy bajo peso al nacer, o<1.000 g peso extremadamente bajo al nacer) y la protocolización de evaluación de función tiroidea en prematuros.Actualizamos los procedimientos diagnósticos, las pruebas imprescindibles y complementarias requeridas, la etiología y los diagnósticos diferenciales en esta patología.

The screening program or early detection of congenital hypothyroidism is one of the greatest advances achieved in Pediatrics. Thyroid hormones are essential for brain development and maturation, which continue into the neonatal stage. Alterations in thyroid function in premature and underweight children in the first months of life causes irreversible damage to the central nervous system and is one of the most frequent and avoidable causes of mental retardation. Diagnosis in the neonatal period is difficult, so it requires an analytical study to be able to carry out the appropriate treatment.The relevance of this problem justifies its communication to all areas of pediatrics. The main objective is to avoid brain damage in these patients. Other aspects to optimize the adequate development of these children with all the necessary periodic controls and to achieve the inclusion of the diagnosis of thyroid alterations during the stay in neonatal units and in the first months of life, need to implement the resources of the health centers and continue advancing according to current knowledge.In this document, we will focus on the screening of preterm newborns VLBW (<32 weeks of gestation) and/or very low weight for gestational age (1500-1000g VLBW or <1000g) and the function evaluation protocol thyroid in premature babies.We update the diagnostic procedures, the essential and complementary tests required, the etiology and the differential diagnoses in this pathology.

The pollution of the planet also reaches the breastfeeding ecosystem, one of the most intimate and inviolable that links us as an animal species to the rest of mammals. Nursing mothers may be concerned about whether the quality of their milk will be adequate for their baby and whether environmental pollutants through work, diet, and storing may adversely affect their child. Breast milk is a source of exposure to environmental pollutants, and at the same time it counteracts much of the effects of these exposures. An approach based on the principles of reality and precaution of environmental health to avoid, reduce or eliminate the production and use of harmful chemicals during pregnancy and lactation would improve the human and planetary health for the offspring.

The precise moment for weaning a patient off extracorporeal membrane oxygenation (ECMO) is not always easy to establish. Also, mechanical causes may obligate to disconnect the patient from the circuit before the optimal weaning off. In these selected cases, the patient can be disconnected from the circuit and the cannula can be left in place (stand-by cannula) until the patient's stability without ECMO is assured. The aim was to describe our experience with the stand-by cannula. Single-institution, long-term retrospective study in a pediatric tertiary care hospital. Neonatal and pediatric patients who were under ECMO and needed stand-by cannula before definitive de-cannulation were included. During 18 years, 166 children required ECMO. In 31 patients (18.7%), stand-by cannula was performed before the weaning off. Twenty patients (64.5%) were newborn. The main reason for requiring ECMO in these newborn was persistent pulmonary hypertension. Eleven patients were pediatric and their main cause for requiring ECMO was cardiogenic shock (six patients, 54.4%). The reasons for requiring stand-by cannula were the uncertainty of a successful weaning off in 17 patients (54.8%), to undergo surgery in 10 patients (32.3%) and to replace the circuit in four cases (12.9%). The median duration of stand-by cannula was 12 h (IQR 6-24). Heparinized saline serum was the main maintenance perfusion (28 patients, 90.3%). Three patients needed to restart support with ECMO. Only one mechanical complication was detected. Stand-by cannula is a safe technique, which allows performing a quick re-entrance on ECMO if the weaning off fails.

BACKGROUND: Autologous stem cell transplantation (ASCT) remains the standard of care for young multiple myeloma (MM) patients; indeed, at-home ASCT has been positioned as an appropriate therapeutic strategy. However, despite the use of prophylactic antibiotics, neutropenic fever (NF) and hospital readmissions continue to pose as the most important limitations in the outpatient setting. It is possible that the febrile episodes may have a non-infectious etiology, and engraftment syndrome could play a more significant role. The aim of this study was to analyze the impact of both G-CSF withdrawal and the addition of primary prophylaxis with corticosteroids after ASCT. METHODS: Between January 2002 and August 2018, 111 MM patients conditioned with melphalan were managed at-home beginning +1 day after ASCT. Three groups were established: Group A (n = 33) received standard G-CSF post-ASCT; group B (n = 32) avoided G-CSF post-ASCT; group C (n = 46) avoided G-CSF yet added corticosteroid prophylaxis post-ASCT. RESULTS: The incidence of NF among the groups was reduced (64%, 44%, and 24%; P<0.001), with a non-significant decrease in hospital readmissions as well (12%, 6%, and 2%; P = 0.07). The most important variables identified for NF were: HCT-CI >2 (OR 6.1; P = 0.002) and G-CSF avoidance plus corticosteroids (OR 0.1; P<0.001); and for hospital readmission: age ≥60 years (OR 14.6; P = 0.04) and G-CSF avoidance plus corticosteroids (OR 0.07; P = 0.05). CONCLUSIONS: G-CSF avoidance and corticosteroid prophylaxis post ASCT minimize the incidence of NF in MM patients undergoing at-home ASCT. This approach should be explored in a prospective randomized clinical trial.

BACKGROUND: The purpose of this paper is to describe how end-of-life care is managed when life-support limitation is decided in a Pediatric Intensive Care Unit and to analyze the influence of the further development of the Palliative Care Unit. METHODS: A 15-year retrospective study of children who died after life-support limitation was initiated in a pediatric intensive care unit. Patients were divided into two groups, pre- and post-palliative care unit development. Epidemiological and clinical data, the decision-making process, and the approach were analyzed. Data was obtained from patient medical records. RESULTS: One hundred seventy-five patients were included. The main reason for admission was respiratory failure (86/175). A previous pathology was present in 152 patients (61/152 were neurological issues). The medical team and family participated together in the decision-making in 145 cases (82.8%). The family made the request in 10 cases (9 vs. 1, p = 0.019). Withdrawal was the main life-support limitation (113/175), followed by withholding life-sustaining treatments (37/175). Withdrawal was more frequent in the post-palliative group (57.4% vs. 74.3%, p = 0.031). In absolute numbers, respiratory support was the main type of support withdrawn. CONCLUSIONS: The main cause of life-support limitation was the unfavourable evolution of the underlying pathology. Families were involved in the decision-making process in a high percentage of the cases. The development of the Palliative Care Unit changed life-support limitation in our unit, with differences detected in the type of patient and in the strategy used. Increased confidence among intensivists when providing end-of-life care, and the availability of a Palliative Care Unit may contribute to improvements in the quality of end-of-life care.

Despite the use of fluoroquinolone (FQ) prophylaxis, neutropenic fever (NF) is the most frequent cause of hospital readmission in ambulatory care programs for patients treated with autologous stem cell transplantation (ASCT). We analyzed the impact of intensifying primary prophylaxis with the addition of piperacillin/tazobactam (PT) to FQ. Between January 2002 and August 2018, 154 lymphoma patients conditioned with BEAM were included (40% received ceftriaxone (Ct) plus FQ and 60% PT plus FQ). NF and hospital readmission were required in 84 vs. 41% (p < .0001) and 12 vs. 1% (p = .007) of patients within the Ct and PT groups, respectively. The multivariate analysis showed that PT plus FQ retained its independent protective factor for NF (odds ratio (OR): 0.13; p < .001) and for hospital readmission (OR: 0.07; p = .01). The use of PT and FQ prophylaxis may effectively prevent episodes of NF and hospitalizations in lymphoma patients managed in our at-home ASCT care model.

BACKGROUND/AIMS: Few data exist on reference thyroid volumes (Tvols) for Spanish children. The standard tables of the World Health Organization (WHO) are only for children older than 6 years. The present cross-sectional study reports the normal Tvols of 3-14 year-old girls and boys living in Madrid (Spain). METHODS: The study subjects were 217 children aged 3-14 years. Urinary iodine was determined, and, on the same day, cervical ultrasound examinations were performed by a single, experienced paediatric radiologist. The sex-specific, upper normal limits for Tvol were then determined, based on age and body surface area (BSA). RESULTS: The median urinary iodine concentration was 120 µg/L (interquartile range 80-184); the population was therefore deemed to fall within the optimum range for iodine nutritional status. Eight children with heterogeneous glandular parenchyma were detected, as were 6 with increased vascularity, and 22 with intrathyroid cysts. Tvol increased with age and BSA in both sexes from the age of 3 years. In girls aged 11-12 years, Tvol was significantly larger than that in boys of the same age. When comparing children 6 years old and above, the 97th percentile Tvols with respect to gender/BSA were similar to WHO reference values, but by gender/age they were 30% larger. CONCLUSIONS: This work proposes reference ultrasound-determined Tvols for 3-14-year-old children living in Madrid.
INTRODUCTION AND OBJECTIVE: Children admitted to the pediatric intensive care unit after cardiovascular surgery usually require treatment with antibiotics due to suspicion of infection. The aim of this study was to assess the effectiveness of procalcitonin in decreasing the duration of antibiotic treatment in children after cardiovascular surgery. METHODS: Prospective, interventional study carried out in a pediatric intensive care unit. Included patients under 18 years old admitted after cardiopulmonary bypass. Two groups were compared, depending on the implementation of the PCT-guided protocol to stop or de-escalate the antibiotic treatment (Group 1, 2011-2013 and group 2, 2014-2018). This new protocol was based on the decrease of the PCT value by 20% or 50% with respect to the maximum value of PCT. Primary endpoints were mortality, stewardship indication, duration of antibiotic treatment, and antibiotic-free days. RESULTS: 886 patients were recruited. There were 226 suspicions of infection (25.5%), and they were confirmed in 38 cases (16.8%). The global rate of infections was 4.3%. 102 patients received broad-spectrum antibiotic (4.7±1.7 days in group 1, 3.9±1 days in group 2 with p = 0.160). The rate of de-escalation was higher in group 2 (30/62, 48.4%) than in group 1 (24/92, 26.1%) with p = 0.004. A reduction of 1.1 days of antibiotic treatment (group 1, 7.7±2.2 and group 2, 6.7±2.2, with p = 0.005) and 2 more antibiotic free-days free in PICU in group 2 were observed (p = 0.001), without adverse outcomes. CONCLUSIONS: Procalcitonin-guided protocol for stewardship after cardiac surgery seems to be safe and useful to decrease the antibiotic exposure. This protocol could help to reduce the duration of broad-spectrum antibiotics and the duration of antibiotics in total, without developing complications or adverse effects.

OBJECTIVE: Three scores have been proposed to stratify the risk of mortality for each cardiac surgical procedure: The RACHS-1, the Aristotle Basic Complexity (ABC), and the STS-EACTS complexity scoring model. The aim was to compare the ability to predict mortality and morbidity of the three scores applied to a specific population. DESIGN: Retrospective, descriptive study. SETTING: Pediatric and neonatal intensive care units in a referral hospital. PATIENTS: Children under 18 years admitted to the intensive care unit after surgery. INTERVENTIONS: None. OUTCOME MEASURES: Demographic, clinical, and surgical data were assessed. Morbidity was considered as prolonged length of stay (LOS > 75 percentile), high respiratory (>72 hours of mechanical ventilation), and high hemodynamic support (inotropic support >20). RESULTS: One thousand and thirty-seven patients were included, in which 205 were newborns (18%). The category 2 was the most frequent in the three scores: In RACHS-1, ABC, 44.9%, and STS-EACTS, 40.8%. Newborns presented significant higher categories. Children required cardiopulmonary bypass in more occasions (P < .001) but the times of bypass and aortic cross-clamp were significantly higher in newborns (P < .001 and P = .016). Thirty-two patients died (2.8%). A quarter of patients had a prolonged LOS, 17%, a high respiratory support, and 7.1%, a high hemodynamic support. RACHS-1 (AUC 0.760) and STS-EACTS (AUC 0.763) were more powerful for predicting mortality and STS-EACTS for predicting prolonged LOS (AUC 0.733) and the need for high respiratory support (AUC 0.742). CONCLUSIONS: STS-EACTS seems to stratify better risk of mortality, prolonged LOS, and need for respiratory support after surgery.

El rotavirus (RV) es la causa principal de diarrea infantil grave en todo el mundo e infecta prácticamente a todos los niños en los primeros 5 años de vida, sobre todo en los primeros 2años. Existen dos vacunas atenuadas de administración oral frente al RV disponibles en nuestro medio que han demostrado ser seguras y eficaces frente a la enfermedad. El objetivo principal de estas vacunas ha sido reproducir la historia natural de la infección y proteger frente a la enfermedad grave en los primeros meses de vida. Los recién nacidos prematuros son especialmente vulnerables a la enfermedad por RV, no solo por tener más riesgo de adquirir la infección, sino también por sus complicaciones. La vacunación frente al RV en niños prematuros ha mostrado resultados de eficacia y seguridad similares a los comunicados en niños a término, y los datos existentes sugieren un riesgo bajo de diseminación e infección nosocomial cuando la vacunación se realiza durante la hospitalización. Dado que un porcentaje estimable de recién nacidos prematuros permanecen ingresados en las unidades neonatales más allá de las 12semanas de vida, se considera que estos, siempre que su condición clínica lo permita, deben recibir la vacunación frente al RV sin retrasos, incluso durante la hospitalización si así fuese necesario
Rotavirus (RV) is the leading cause of severe acute gastroenteritis in infants worldwide. Most children are infected by RV by the age of 5 years, and especially in the first 2 years. Two oral attenuated vaccines against RV are licensed in industrialised countries, which have proven to be safe and effective against the disease. The main objective of these vaccines has been to reproduce the natural history of infection and protect against severe disease in the first months of life. Preterm infants are at higher risk of severe RV infection compared to full-term infants and infants with normal birth weight. Data collected on RV vaccination in preterm infants demonstrated that RV vaccines are effective and safe, compared with full-term infants, with a marginal risk of horizontal viral transmission and dissemination when vaccination is performed during hospitalisation. Preterm infants frequently require admission to hospital after the beginning of the 12 th week of life, which suggests that they should receive RV vaccines during admission according to the official immunisation schedule

Este artículo actualiza los objetivos, los procedimientos diagnósticos, las pruebas imprescindibles y complementarias requeridas, la etiología y los diagnósticos diferenciales en esta patología. Con especial énfasis en los requerimientos de los centros de seguimiento para protocolizar los resultados del tratamiento con L-tiroxina administrada de forma inmediata al diagnóstico y a las dosis que eviten fases de infra o supradosificación que pueden alterar diversos aspectos del desarrollo cognitivo. La revaluación de etiología permanente vs. transitoria se recomienda siempre después de los 3 años de edad. La relevancia de este programa precisa su difusión a todas las áreas de pediatría. El objetivo principal, evitar el daño cerebral en estos pacientes, se ha logrado y es además altamente beneficioso desde el punto de vista económico. Otros aspectos para optimizar los resultados cognitivos con todos los controles periódicos necesarios y lograr la inclusión del diagnóstico del HC central, precisan implementar los recursos de los centros de seguimiento y continuar avanzando según los conocimientos actuales
The screening program of congenital hypothyroidism (CH) is probably one of the best achievements in paediatrics. Thyroid hormones are essential for brain development and brain maturation that continue through the neonatal period. Hypothyroidism that begins in the first months of life causes irreversible damage to the central nervous system, and is one of the most frequent and preventable causes of mental retardation. As children with congenital hypothyroidism are born with a normal appearance, analytical studies are required to immediately start the appropriate therapy. This article analyses the aims, diagnostic procedures, tests required, aetiology, and differential diagnosis in this disorder. Especially relevant is to perform frequent monitoring to ensure dose adjustments of L-Thyroxine therapy, avoiding infra- or supra-dosing that negatively affects neurosensory functions. Re-evaluation of the aetiology permanent vs transient hypothyroidism is always recommended after 3 years of chronological age. The relevance of this screening program should be widely discussed in paediatrics. The main objective is to avoid cerebral damage in these patients and has been highly successful and economically beneficial. Other aspects are required to optimise patient outcomes, to perform all the controls according to the recommendations and to include, in the near future, the diagnosis of central hypothyroidism. Implementation of this program is necessary to progress in accordance with current scientific knowledge

BACKGROUND & AIMS: Iodine deficiency inhibits the normal development of human beings and is the leading cause of preventable mental retardation. Our study aims to update the urinary iodine concentrations and the intake of iodized salt in children in Madrid (Spain). METHODS: A cross-sectional study was designed where 217 children aged 3-14 years old were studied. A nutritional survey including the intake of iodized salt and other iodine-rich foods was performed. In addition, the urinary concentration of iodine was determined in each patient. RESULTS: Near 60% of the surveyed households routinely used iodized salt. Significant differences in age, sex, country of birth, or country of birth and parents educational levels and iodized salt consumption were not found. The median of the urinary iodine level (120 µg/L; interquartile range 80-184) was significantly higher in boys than girls and more elevated in younger children. Iodized salt and milk consumption significantly increased the concentration of urinary iodine. Children who drank less than two glasses of milk per day and did not consume iodized salt have four times the risk of iodine deficiency compared to children who daily drank at least two glasses of milk and consumed iodized salt (P < 0.001). CONCLUSIONS: The nutritional level of iodine in the children studied is appropriate despite the low consumption of iodized salt. This is due to the consumption of dairy products and milk. The younger the child, the better his/her iodine nutritional level. Teenagers studied are at higher risk of iodine deficiency.
