Apneas en lactantes con bronquiolitis: incidencia y factores de riesgo para un modelo de predicción

Introduction

The presence of apnoea in acute bronchiolitis (AB) varies between 1.2% and 28.8%, depending on the series, and is one of its most fearsome complications. The aim of this study is to determine the incidence of apnoea in hospitalised patients diagnosed with AB, and to define their associated risk factors in order to construct a prediction model.

Metilfenidato en el tratamiento del trastorno de déficit de atención con hiperactividad en pediatría: monitorización en matrices biológicas

Attention-deficit hyperactivity disorder (ADHD) has emerged in the last few years as the most commonly diagnosed and treated psychiatric disorder in the paediatric population. In 1980's, methylphenidate (MFD) a psychomotor stimulant drug, was approved in Spain for the symptomatic therapy of ADHD. Since then, MFD has become one of the most extensively prescribed and studied treatment for ADHD both in children and adults.In this paper, the main pharmacological issues of MFD are reviewed, focusing on its pharmacokinetics in conventional (blood and urine) and non-conventional (hair, oral fluid and sweat) biological matrices, its pharmaceutical preparations, therapeutic levels and side effects.     

Actualización del tratamiento de la tuberculosis en niños

Tuberculosis (TB) is the most important infectious disease all over the world, with a high morbidity and mortality. Pediatric tuberculosis has been a neglected epidemic, due to the difficulties in assessing its global impact, reduced incidence and lower infectivity compared to adults. In 2015, the WHO reported 1 million cases of paediatric TB and 169,000 deaths. In Europe, the emergence of MDR TB is a major concern, representing 16% of the new diagnosis in Eastern Europe. In 2014, it was estimated that about 219,000 children were infected by MDR-TB-strains in Europe, and 2,120 developed the disease. Spain is the Western European country with more paediatric cases, with an incidence 4.3/100,000 inhabitants in 2014. Paediatric tuberculosis mortality in Spain is rare, but extra-pulmonary disease is associated with significant complications. The prevalence of paediatric drug resistant TB in Spain is over 4%, higher than the estimated incidence in adult population, representing mayor difficulties for therapeutic intervention. These data reveal that paediatric TB is still a Public Health priority in our country.The difficulties in diagnosis and the lack of optimal paediatric drug formulations are the major challenges for controlling the childhood's tuberculosis epidemic. A group of national paeditric TB experts has reviewed the international guidelines and the most recent evidences, and has established new recommendations for the management of paediatric TB contacts, latent infection and active TB disease, especially focused in drug resistant cases. This document replaces the former national guidelines from the Spanish Society for Pediatric Infectios Diseases, although the prior recommendations on the diagnosis remain valid.     

Oxigenoterapia de alto flujo con cánula nasal en el tratamiento de la bronquiolitis aguda en neonatos

ObjectiveTo determine whether the availability of heated humidified high-flow nasal cannula (HFNC) therapy was associated with a decrease in need for mechanical ventilation in neonates hospitalised with acute bronchiolitis.MethodsA combined retrospective and prospective (ambispective) cohort study was performed in a type II-B Neonatal Unit, including hospitalised neonates with acute bronchiolitis after the introduction of HFNC (HFNC-period; October 2011-April 2015). They were compared with a historical cohort prior to the availability of this technique (pre-HFNC; January 2008-May 2011). The need for mechanical ventilation between the two study groups was analysed. Clinical parameters and technique-related complications were evaluated in neonates treated with HFNC.ResultsA total of 112 neonates were included, 56 after the introduction of HFNC and 56 from the period before the introduction of HFNC. None of patients in the HFNC-period required intubation, compared with 3.6% of the patients in the pre-HFNC group. The availability of HFNC resulted in a significant decrease in the need for non-invasive mechanical ventilation (30.4% vs 10.7%; P = .01), with a relative risk (RR) of .353 (95% CI; .150-.829), an absolute risk reduction (ARR) of 19.6% (95% CI; 5.13 - 34.2), yielding a NNT of 5. In the HFNC-period, 22 patients received high flow therapy, and 22.7% (95% CI; 7.8 to 45.4) required non-invasive ventilation. Treatment with HFNC was associated with a significant decrease in heart rate (P = .03), respiratory rate (P = .01), and an improvement in the Wood-Downes Férres score (P = .00). No adverse effects were observed.ConclusionsThe availability of HFNC reduces the need for non-invasive mechanical ventilation, allowing a safe and effective medical management of neonates with acute bronchiolitis.     

Impacto clínico de la implantación de la ventilación por alto flujo de oxígeno en el tratamiento de la bronquiolitis en una planta de hospitalización pediátrica

ObjectiveTo analyse the safety and efficacy of high-flow oxygen therapy for treatment of moderate to severe bronchiolitis in children admitted to the paediatric hospital wards.MethodsA prospective observational study was conducted on children < 18 months of age with bronchiolitis admitted to the paediatric ward of a tertiary-care teaching hospital during the 2011-12 respiratory season. Children were treated with a high-flow ventilation system (Fisher & Paykel). Clinical and cardio-respiratory parameters were evaluated every hour for the duration of therapy.ResultsA total of 25 patients, with a median age of 2 months (range: 0.6-11 months) were included. Respiratory syncytial virus (RSV) was positive in 75% of cases. Indications for high-flow therapy included: progressive respiratory distress (Wood-Downes ≥ 8) (88%), apnoea (8%) and desaturation (4%). Median duration of therapy was 4 days (range: 3-7 days), with a median of 9 days in hospital (range: 8-12 days). High flow therapy was associated with a significant decrease in cardio-respiratory parameters, heart rate, respiratory rate, which resulted in a significant improvement of the Wood-Downes Score (from 10±1.21 to 3±0.77, P=.001). No adverse effects were observed. Five patients (20%) were admitted to the Paediatric Intensive Care Unit (PICU), which represents an 80% reduction of PICU admissions compared with historic data of previous years.ConclusionsHigh-flow ventilation therapy achieved a significant improvement in heart rate, respiratory rate, and scale of severity in patients with bronchiolitis. This novel therapeutic strategy allows safe management of bronchiolitis patients in the regular ward, reducing admissions to the PICU.     

Calidad de vida relacionada con la salud en casos de trastorno por déficit de atención con hiperactividad con/sin tratamiento farmacológico

IntroductionThe health-related quality of life (HRQoL) questionnaire is important in order to assess the effects of therapeutic intervention. The aim of this study is to analyse HRQoL, comparing cases of attention deficit hyperactivity disorder (ADHD) treated with methylphenidate (ADHD-T), untreated cases (ADHD-N), and controls.Material and methodsThe study included a sample of 228 participants between 8 and 14 years old (114 controls, 57 ADHD-T, and 57 ADHD-N). Consecutive sampling was used in ADHD according to DSM-IV criteria (ADHD Rating Scales IV), and random sampling of controls matched by gender and age. The evaluation of HRQoL was made by using KIDSCREEN-52 parent version.ResultsThe intensity of ADHD symptoms is significantly lower in ADHD-T than in ADHD-N. There is a moderate significant correlation between greater intensity of ADHD symptoms and worse HRQoL. ADHD cases have significantly worse HRQoL than controls on psychic well-being, mood, relationship with parents and friends, school environment, and social acceptance. The cases of ADHD-T have significantly better HRQoL than ADHD-N in the school dimension, but do not differ significantly in other dimensions of KIDSCREEN-52.ConclusionsIt would be advisable that the treatment of ADHD integrates multi-dimensional therapeutic models that improve the basic symptoms of the disorder, as well as the HRQoL.     

Actualización en el diagnóstico y tratamiento de la malaria

An increase in the cases of malaria in our country has been observed due to immigration, and adopted children. Malaria management requires an integrate approach, including prompt diagnoses and treatment to avoid the associated morbidity and mortality. In the last years, new recommendations have been introduced due to the appearance of new resistant areas. In this article we aim to provide a summary of the key recommendations following the main malaria guidelines (WHO and CDC).     

Evaluación de la calidad de vida en escolares con antecedentes de desnutrición temprana severa

IntroductionSevere malnutrition in young children may lead to long-term complications, in particular learning and psychosocial disorders linked to health related quality of life (HRQOL). The aim of this study was to evaluate HRQOL in children whit a history of severe malnutrition before 2 years of life, expecting to find lower scores in these patients.Material and methodA comparative study was performed on schoolchildren between 5 and 12 years with a history of early severe malnutrition, excluding those with chronic diseases. The Controls were healthy siblings of patients. The sample size was estimated as 26 subjects per group (Total = 52). Sociodemographic variables were recorded and the HRQOL was assessed with PedsQL4.0. Chi square and Student t test were applied. Significance level: P < .05.ResultsA total of 25 patients and 28 controls were studied. The HRQOL scores obtained from PedsQL for children with history of malnutrition, compared with their healthy siblings, were: Total: 80.82 ± 1.94 vs 89.18 ± 1.84 P < .0001), physical health/dimension: 87.75 ± 3.37 vs 94.75 ± 1.87 (P < .0001), psychosocial health: 77.77 ± 2.90 vs 86.57 ± 1.42 (P < .0001), emotional dimension: 67.80 ± 4.40 vs 78.75 ± 2.96 (P < .0001), social dimension: 88.80 ± 3.05 vs 95.71 ± 1.52 (P < .0001), and school dimension: 74.58 ± 3.80 vs 85.00 ± 3.51 (P < .0001).ConclusionsPatients with a history of early severe malnutrition, showed significantly lower HRQOL scores compared with controls.     

Evaluación del seguimiento de niños con hallazgo de hipertransaminasemia

IntroductionAlthough changes in liver function tests can be non-specific in numerous clinical conditions, they can be the first sign of a potentially serious disease in an asymptomatic patient.Material and methodsRetrospective cohort study, performed by reviewing the records of children of a reference hospital central laboratory with alanine aminorransferase enzyme (ALT) elevation during a 6 month aleatory period.Results572 blood tests with serum ALT elevation corresponding to 403 patients had been assessed during the period studied. 98 patients were excluded for presenting abnormal liver test before the study period of comorbidity that could produce ALT elevation. The remaining 305 patients, 22.6% were diagnosed with a medical condition during the first blood test that explained the ALT elevation, although only 33.3% of them were followed up until verifying their normalization. Final study sample consists of 236 patients with abnormal liver test without apparent liver disease. Adequate follow-up was found only in 29% of them. From this group, 9 patients (13%) were diagnosed with liver disease. The rest of the sample were not properly monitored. In patients with higher serum ALT levels, follow-up was early and more appropiate.ConclusionsIn our area, most children without apparent liver disease are no properly monitored. Therefore, an opportunity to diagnosis and treat a potential liver disease was lost in a great number of children. All children with unexplainedhypertransaminasaemia must be studied.     

Evolución del peso del prematuro con alta precoz y atención domiciliaria de enfermería

IntroductionIn-Home nursing care of the preterm newborn helps to bring the family situation to normal, promotes breastfeeding and development of the newborn, and enables the reorganization of health care resources. The purpose of this paper is to demonstrate that in-home nursing care of the preterm newborn leads to an increase in weight and a similar morbidity.Patients and methodologyA total of 65 cases and 65 controls (matched by weight, age and sex) were studied, all of them preterm newborns born in hospital and weighing less than 2100 g at discharge. In-home nursing care was carried out by a pediatrician neonatologist, as well as two nurses specialized in neonatology who made several visits to the home. Weight gain was calculated as g/day and g/Kg/day, comparing the first week of the study with the week prior to the beginning of the study.ResultsThe groups were comparable. Weight gain in the group with home nursing care was 38 g per day, significantly higher than the weight gain in the control group (31 g/day). The independent predictive variables of the increase in g/Kg/day during the study were in-home nursing care, male gender, breastfeeding less, and not having suffered from a peri-intraventricular hemorrhage. Neonatal morbidity was similar in both groups.ConclusionsIn-home care was associated with a greater weight gain of the newborn at home than during their stay in the hospital, and can be considered safe because neonatal morbidity was not increased
