Epidemiología molecular de la colonización nasofaríngea neumocócica en niños de Sevilla, tras la implementación del programa de vacunación con VNC13 en Andalucía (España) / Molecular epidemiology of pneumococcal carriage in children from Seville, following implementation of the PCV13 immunization program in Andalusia, Spain

Introducción: El programa de vacunación universal con la vacuna antineumocócica conjugada 13-valente (VNC13) se implantó en Andalucía en diciembre de 2016. Métodos: Estudio transversal de colonización nasofaríngea por Streptococcus pneumoniae. Se seleccionó a 397 niños sanos en centros de atención primaria de Sevilla durante los periodos 1/4/2018-28/2/2020 y 1/11/2021-28/2/2022 (periodo VNC13). Se utilizó una colección histórica de un estudio de colonización desarrollado en niños sanos y con infección respiratoria superior entre el 1/01/2006 y el 30/06/2008 (periodo VNC7) para comparar las distribuciones de serotipos/genotipos y las tasas de resistencias antibióticas. Resultados: Un total de 76 (19%) niños estaban colonizados con S. pneumoniae en el periodo VNC13 y se dispuso de 154 aislamientos del periodo VNC7. La colonización por serotipos incluidos en VNC13 disminuyó significativamente entre los periodos VNC13 y VNC7 (11 vs. 38%; p=0,0001); los serotipos 19F (8%), 3 (1%) y 6B (1%) fueron los únicos serotipos vacunales circulantes. Los serotipos 15B/C y 11A fueron los serotipos no VNC13 más prevalentes durante el periodo VNC13 (14% y 11%, respectivamente); este último se incrementó de forma significativa entre periodos de tiempo (p=0,04). El serotipo 11A solo se asoció en el periodo VNC13 con variantes resistentes a la ampicilina del clon Spain9V-ST156 (ST6521 y genéticamente relacionado ST14698), no detectados en el periodo anterior. Conclusiones: Hubo una circulación muy residual de los serotipos vacunales durante el periodo VNC13, con excepción del serotipo19F. El serotipo 11A se incrementó de forma significativa entre los periodos VNC13 y VNC7 por expansión clonal del genotipo resistente a la ampicilina ST6521.(AU)

Background: The 13-valent pneumococcal conjugate vaccine (PCV13) universal vaccination program was introduced in December 2016 in Andalusia. Methods: A cross-sectional study was conducted on the molecular epidemiology of pneumococcal nasopharyngeal colonization. A total of 397 healthy children were recruited from primary healthcare centres in Seville for the periods 1/4/2018 to 28/2/2020 and 1/11/2021 to 28/2/2022 (PCV13 period). Data from a previous carriage study conducted among healthy and sick children from 1/01/2006 to 30/06/2008 (PCV7 period) were used for comparison of serotype/genotype distributions and antibiotic resistance rates. Results: Overall, 76 (19%) children were colonized with S. pneumoniae during the PCV13 period and there were information available from 154 isolates collected during the PCV7 period. Colonization with PCV13 serotypes declined significantly in the PCV13 period compared with historical controls (11 vs. 38%, P=0.0001), being serotypes 19F (8%), 3 (1%) and 6B (1%) the only circulating vaccine types. Serotypes 15B/C and 11A were the most frequently identified non-PCV13 serotypes during the PCV13 period (14% and 11%, respectively); the later one increased significantly between time periods (P=0.04). Serotype 11A was exclusively associated in the PCV13 period with ampicillin-resistant variants of the Spain9V-ST156 clone (ST6521 and genetically related ST14698), not detected in the preceding period. Conclusions: There was a residual circulation of vaccine types following PCV13 introduction, apart from serotype 19F. Serotype 11A increased between PCV13 and PCV7 periods due to emergence and clonal expansion of ampicillin-resistant genotype ST6521.(AU)

Melatonina en trastornos del sueño: comparación de distintos productos y revisión bibliográfica / Melatonin in sleep disorders. comparison of different products and literature review

Introducción: los trastornos del sueño en Pediatría son un problema creciente. La melatonina es el producto de elección y es común recibir publicidad de múltiples productos que la contienen. En este texto se lleva a cabo un análisis comparativo de los mismos, examinando la evidencia científica más reciente, con el fin de determinar si está justificado o no su uso. Métodos: se ha realizado un estudio descriptivo de los productos que contenían melatonina comercializados en España, de venta en farmacias y dirigidos a la población pediátrica. Posteriormente, se ha llevado a cabo una revisión de documentos sobre el uso de melatonina en niños y sobre cada componente extra presente en los productos recogidos. Resultados: se analizaron 53 productos. La forma de administración mayoritaria fue en gotas o mililitros. La dosis recomendada habitual de melatonina fue de 1 mg al día. El componente añadido más frecuente registrado fue la vitamina B6, y melisa y pasiflora fueron las plantas más utilizadas. Ninguno de los productos estaba catalogado como fármaco por la Agencia Española de Medicamentos y Productos Sanitarios (AEMPS) y tampoco se encontró en la publicidad de ninguno referencias bibliográficas. Conclusiones: aunque es conocida la eficacia de la melatonina en trastornos del sueño, actualmente no hay un consenso sobre su dosis eficaz en edad pediátrica. Las sustancias que más frecuentemente se asocian a melatonina cuentan con poca bibliografía que respalde sus resultados sobre el sueño, además de que para ellas tampoco existen, de momento, dosis estandarizadas para la población infantil. (AU)

Introduction: sleep disorders in paediatrics are a growing problem. Melatonin is the drug of choice and it is common to receive advertising for multiple products containing melatonin in primary care. In this paper, a comparative analysis of these products is carried out, examining the most recent scientific evidence, in order to determine whether their use is justified or not. Methods: a descriptive study was conducted on melatonin-containing products sold in pharmacies in Spain and aimed at the paediatric population. Subsequently, a systematic review of documents on the use of melatonin in children and on each extra component present in the products collected was carried out. Results: fifty-three products were analysed. The most common form of administration was drops or millilitres. The usual recommended dose of melatonin was 1 mg per day. The most frequently reported added component was vitamin B6, and lemon balm and passionflower were the most frequently used herbs. None of the products were specifically listed in the Spanish Agency for Medicines and Health Products, and no bibliographical references were found in the advertising of any of the products. Conclusions: although the efficacy of melatonin in sleep disorders is well known, there is currently no consensus on its effective dose in children. The substances most frequently associated with melatonin have little literature to support their results in sleep, and there are no standardised doses for them either, or doses lower than these are used due to a lack of studies in the paediatric population.

Absceso mamario neonatal / Neonatal breast abscess: a case report

Presentamos el caso de una niña de 27 días de vida, sin antecedentes de interés, que acude a su pediatra por edema y hematoma en la mama derecha. La paciente acude al día siguiente a las urgencias hospitalarias por evolución del cuadro hacia un absceso mamario, teniendo que ser ingresada e iniciando tratamiento antibiótico intravenoso. Dada la mala evolución, y a pesar del tratamiento antibiótico, se decide intervención quirúrgica mediante drenaje y lavado de la cavidad. Finalmente, se resuelve el cuadro sin secuelas posteriores. (AU)

We present a 27-day-old girl with no significant medical history who attended pediatric consultation presenting with edema and hematoma in her right breast. The patient was admitted the next day following examination in ER due to the worsening of a starting breast abscess and was treated with intravenous antibiotic therapy. Due to the worsening of the condition and despite the intravenous antibiotic therapy, a surgical treatment was performed consisting in draining the abscess and washing the cavity. Finally, the problem was solved without any consequences. (AU)

Efficacy and tolerability of SEDIFLÙ in treating dry or productive cough in the pediatric population (SEPEDIA): A pilot, randomized, double-blind, placebo-controlled, multicenter clinical trial.

The aim of this trial was to assess the effectiveness of Sediflù, a medical device containing active herbal ingredients, on nocturnal and diurnal persistent coughs in children, with a duration of 3 to 7 days. Children with a dry and/or productive cough were enrolled in this prospective, interventional, multicenter, placebo-controlled, double-blind, randomized clinical study. Clinical efficacy was assessed through the evaluation of the soothing action of Sediflù against dry and/or productive coughing, both at night and during the day, and other effects of coughing associated with quality of sleep: frequency, child's quality of sleep, parental quality of sleep and severity. Treatment with Sediflù improved both night-time and day-time cough scores from day 2. The diurnal score also improved significantly in the Sediflù group at days 3 and 7. Sediflù syrup can be considered a valid treatment for cough management in younger children with upper respiratory tract infections, shortening the cough duration.

A Single-Center Retrospective Study of Pediatric Vitiligo in a Tertiary Hospital.

Vitiligo is a common disorder; however, its management is unknown by many primary-care doctors and pediatricians. Most articles focus on adults; we analyze the characteristics and impact on children. A single-center retrospective study was conducted over 10 years on 254 children diagnosed with vitiligo. About 50.4% were male with a mean age of 8.24 years. There was a slight predominance of nonsegmented vitiligo. About 12.59% had family history of vitiligo and 11.4% of autoimmune diseases. Around 15.7% patients presented other dermatological diseases and 9.05%, autoimmune diseases. No significant statistical differences were found when comparing age, sex, and type of vitiligo with other variables. Almost 96.06% received treatment with calcineurin inhibitors and 66.53% topical steroids. Around 77% obtained repigmentation, and out of the initial nonresponders, 16% responded to phototherapy. In general, our results concur with the scarce literature. A long-term follow-up of children with vitiligo is needed to identify treatment side effects and diseases associated.

Mutismo selectivo: cuando la timidez se hace extrema / Selective mutism: when shyness becomes extreme

El mutismo selectivo es un trastorno poco frecuente y a menudo infradiagnosticado, que puede afectar al rendimiento escolar y repercutir negativamente en su desarrollo. Ocurre antes de los 5 años y está caracterizado por la incapacidad de comunicarse en ámbitos donde el niño no se siente cómodo, como puede ser la escuela; en cambio, en otros lugares, como el domicilio, se comunica y actúa sin problemas. Genera inquietud familiar. Su tratamiento principal es la terapia cognitivo conductual. La combinación de esta terapia con la administración de fármacos se reserva para casos más graves. Se describe a continuación un caso diagnosticado hace 6 meses y en tratamiento desde entonces (AU)

Selective mutism is a less frequent disorder, often underdiagnosed, which negatively affects the child’s development and school performance. This disorder takes place before the age of five. It is characterized with the incapacity to speak in places where the child does not feel comfortable, as school, but at home they speak without problem. In fact, the detection occurs at school, and generates family distress due to their surprise for their child’s attitude. The treatment is based on cognitive-conductive therapy, and just in severe cases pharmacotherapy is needed. A case diagnosed 6 months ago and under treatment since then is described below. (AU)

Molecular epidemiology of pneumococcal carriage in children from Seville, following implementation of the PCV13 immunization program in Andalusia, Spain.

INTRODUCTION: The 13-valent pneumococcal conjugate vaccine (PCV13) universal vaccination programme was introduced in December 2016 in Andalusia. METHODS: A cross-sectional study was conducted on the molecular epidemiology of pneumococcal nasopharyngeal colonization. A total of 397 healthy children were recruited from primary healthcare centres in Seville for the periods 1/4/2018 to 28/2/2020 and 1/11/2021 to 28/2/2022 (PCV13 period). Data from a previous carriage study conducted among healthy and sick children from 1/01/2006 to 30/06/2008 (PCV7 period), were used for comparison of serotype/genotype distributions and antibiotic resistance rates. RESULTS: Overall, 76 (19%) children were colonized with S. pneumoniae during the PCV13 period and there were information available from 154 isolates collected during the PCV7 period. Colonization with PCV13 serotypes declined significantly in the PCV13 period compared with historical controls (11% vs 38%, p = 0.0001), being serotypes 19F (8%), 3 (1%) and 6B (1%) the only circulating vaccine types. Serotypes 15B/C and 11A were the most frequently identified non-PCV13 serotypes during the PCV13 period (14% and 11%, respectively); the later one increased significantly between time periods (p = 0.04). Serotype 11A was exclusively associated in the PCV13 period with ampicillin-resistant variants of the Spain9V-ST156 clone (ST6521 and genetically related ST14698), not detected in the preceding period. CONCLUSIONS: There was a residual circulation of vaccine types following PCV13 introduction, apart from serotype 19F. Serotype 11A increased between PCV13 and PCV7 periods due to emergence and clonal expansion of ampicillin-resistant genotype ST6521.

Clinical utility of urinary gluten immunogenic peptides in the follow-up of patients with coeliac disease.

BACKGROUND: Gluten-free diet (GFD) is the only treatment for patients with coeliac disease (CD) and its compliance should be monitored to avoid cumulative damage. AIMS: To analyse gluten exposures of coeliac patients on GFD for at least 24 months using different monitoring tools and its impact on duodenal histology at 12-month follow-up and evaluate the interval of determination of urinary gluten immunogenic peptides (u-GIP) for the monitoring of GFD adherence. METHODS: Ninety-four patients with CD on a GFD for at least 24 months were prospectively included. Symptoms, serology, CDAT questionnaire, and u-GIP (three samples/visit) were analysed at inclusion, 3, 6, and 12 months. Duodenal biopsy was performed at inclusion and 12 months. RESULTS: At inclusion, 25.8% presented duodenal mucosal damage; at 12 months, this percentage reduced by half. This histological improvement was indicated by a reduction in u-GIP but did not correlate with the remaining tools. The determination of u-GIP detected a higher number of transgressions than serology, regardless of histological evolution type. The presence of >4 u-GIP-positive samples out of 12 collected during 12 months predicted histological lesion with a specificity of 93%. Most patients (94%) with negative u-GIP in ≥2 follow-up visits showed the absence of histological lesions (p < 0.05). CONCLUSION: This study suggests that the frequency of recurrent gluten exposures, according to serial determination of u-GIP, could be related to the persistence of villous atrophy and that a more regular follow-up every 6 months, instead of annually, provides more useful data about the adequate adherence to GFD and mucosal healing.

Seawater products for nasal lavages. Comparison and literature review / Productos de agua de mar para lavados nasales. Comparación y revisión bibliográfica

Introduction. There is a wide range of seawater products for nasal lavages. Their efficacy and superiority over conventional saline solutions are not well established. Objectives. To analyse the best-selling seawater products, as well as reviewing the most recent literature regarding nasal lavages. Methods. Comparative study of composition, administration mode, age indicated for its use, price and bibliography provided on the web of the seawater products usually available in pharmacies. Analysis of the bibliography provided and review of the scientific evidence regarding nasal lavages with saline solutions or seawater. Results. 44 products from 11 manufacturers were analysed. The concentration of sodium chloride varies from 0.9% to 2.5%. The most frequent mode of application is spray. The addition of plants, salts and other components is common. Only two brands provide bibliographic references on their website. According to the literature reviewed, both saline solutions and seawater seem especially useful in the treatment of upper respiratory tract infections and allergic rhinitis. Conclusions. There is no solid scientific evidence regarding the benefits of nasal lavages. With the current evidence it is not possible to recommend seawater over conventional saline or to establish the optimal concentration of the solution or the most convenient mode of administration. The addition of elements to seawater solutions is not justified enough.

Effects of a Novel Infant Formula on Weight Gain, Body Composition, Safety and Tolerability to Infants: The INNOVA 2020 Study.

Exclusive breastfeeding is recommended for the first six months of life to promote adequate infant growth and development, and to reduce infant morbidity and mortality. However, whenever some mothers are not able to breastfeed their infants, infant formulas mimicking human milk are needed, and the safety and efficacy of each formula should be tested. Here, we report the results of a multicenter, randomized, blinded, controlled clinical trial that aimed to evaluate a novel starting formula on weight gain and body composition of infants up to 6 and 12 months, as well as safety and tolerability. For the intervention period, infants were divided into three groups: group 1 received formula 1 (Nutribén® Innova 1 (Alter Farmacia S.A., Madrid, Spain) or INN (n = 70)), with a lower amount of protein, a lower casein to whey protein ratio by increasing the content of α-lactalbumin, and a double amount of docosahexaenoic acid/arachidonic acid than the standard formula; it also contained a thermally inactivated postbiotic (Bifidobacterium animalis subsp. lactis, BPL1TM HT). Group 2 received the standard formula or formula 2 (Nutriben® Natal (Alter Farmacia S.A., Madrid, Spain) or STD (n = 70)) and the third group was exclusively breastfed for exploratory analysis and used as a reference (BFD group (n = 70)). During the study, visits were made at 21 days and 2, 4, 6, and 12 months of age. Weight gain was higher in both formula groups than in the BFD group at 6 and 12 months, whereas no differences were found between STD and INN groups either at 6 or at 12 months. Likewise, body mass index was higher in infants fed the two formulas compared with the BFD group. Regarding body composition, length, head circumference and tricipital/subscapular skinfolds were alike between groups. The INN formula was considered safe as weight gain and body composition were within the normal limits, according to WHO standards. The BFD group exhibited more liquid consistency in the stools compared to both formula groups. All groups showed similar digestive tolerance and infant behavior. However, a higher frequency of gastrointestinal symptoms was reported by the STD formula group (n = 291), followed by the INN formula (n = 282), and the BFD groups (n = 227). There were fewer respiratory, thoracic, and mediastinal disorders among BFD children. Additionally, infants receiving the INN formula experienced significantly fewer general disorders and disturbances than those receiving the STD formula. Indeed, atopic dermatitis, bronchitis, and bronchiolitis were significantly more prevalent among infants who were fed the STD formula compared to those fed the INN formula or breastfed. To evaluate whether there were significant differences between formula treatments, beyond growth parameters, it would seem necessary to examine more precise health biomarkers and to carry out long-term longitudinal studies.

Negative predictive value of the repeated absence of gluten immunogenic peptides in the urine of treated celiac patients in predicting mucosal healing: new proposals for follow-up in celiac disease.

BACKGROUND: The treatment of celiac disease (CD) is a lifelong gluten-free diet (GFD). The current methods for monitoring GFD conformance, such as a dietary questionnaire or serology tests, may be inaccurate in detecting dietary transgressions, and duodenal biopsies are invasive, expensive, and not a routine monitoring technique. OBJECTIVES: Our aim was to determine the clinical usefulness of urine gluten immunogenic peptides (GIP) as a biomarker monitoring GFD adherence in celiac patients and to evaluate the concordance of the results with the degree of mucosal damage. METHODS: A prospective observational study was conducted involving 22 de novo CD patients, 77 celiac patients consuming a GFD, and 13 nonceliac subjects. On 3 d of the week, urine samples were collected and the GIP concentrations were tested. Simultaneously, anti-tissue transglutaminase antibodies, questionnaire results, clinical manifestations, and histological findings were analyzed. RESULTS: Approximately 24% (18 of 76) of the celiac patients consuming a GFD exhibited Marsh II-III mucosal damage. Among this population, 94% (17 of 18) had detectable urine GIP; however, between 60% and 80% were asymptomatic and exhibited negative serology and appropriate GFD adherence based on the questionnaire. In contrast, 97% (31 of 32) of the celiac patients without duodenal damage had no detectable GIP. These results demonstrated the high sensitivity (94%) and negative predictive value (97%) of GIP measurements in relation to duodenal biopsy findings. In the de novo CD-diagnosed cohort, 82% (18 of 22) of patients had measurable amounts of GIP in the urine. CONCLUSIONS: Determining GIP concentrations in several urine samples may be an especially convenient approach to assess recent gluten exposure in celiac patients and appears to accurately predict the absence of histological lesions. The introduction of GIP testing as an assessment technique for GFD adherence may help in ascertaining dietary compliance and to target the most suitable intervention during follow-up.

Efecto de la alimentación del lactante en la excreción de inmunopéptidos del gluten en heces / Influence of infant feeding on the excretion of gluten immunopeptides in feces

Introducción: la secreción de antígenos de la dieta en la leche materna ha sido ampliamente documentada. La transferencia de gliadina podría ser crítica para el desarrollo de una respuesta inmune. Objetivos: investigar la presencia de péptidos inmunogénicos de gluten en heces de lactantes alimentados con diversos regímenes. Material y métodos: estudio ciego, prospectivo, controlado, colaborativo entre tres centros hospitalarios y desarrollado entre septiembre de 2016 y enero de 2017. El protocolo del estudio fue aprobado previamente por el Comité de Ética de los hospitales de Sevilla. Resultados: se reclutaron 90 niños divididos en tres grupos de 30 niños. Un grupo experimental (edad media de 9,2 ± 2,8 semanas) con lactancia materna exclusiva; un grupo control1 (edad media 10,3 ± 3,3 semanas), alimentados con fórmula de inicio de forma exclusiva y en el que en ninguno de sus integrantes se detectó un test positivo del péptido 33-mer de gliadina en heces; y un grupo control2 con lactantes que consumían gluten en forma habitual (edades promedio 56 semanas ± 3,7 semanas) y que en un 23% (siete casos) tampoco excretaron en sus heces el PIG 33-mer. No se apreció diferencia en la cantidad de gluten ingerida por estos niños y por los que sí excretaron el péptido 33-mer en sus heces. Conclusiones: el hecho de no detectar gluten en heces de lactantes alimentados con leche materna exclusiva indica que probablemente este se encuentre por debajo de los límites para su detección. Hay niños sanos de un año de edad que, aunque consumen gluten, no lo excretan en heces

Introduction: the secretion of antigens from the diet into breast milk has been extensively documented. The transfer of gliadin could be critical for the development of an immune response. Objectives: to investigate the presence of immunogenic gluten peptides in the feces of infants fed with different diets. Material and methods: a blind, prospective, controlled, collaborative study was performed in three hospitals, between September 2016 and January 2017. The study protocol was approved by the Ethics Committee of the hospitals in Seville prior to starting the study. Results: the cohort was divided into three groups of 30 infants: an experimental group (average age 9.2 ± 2.8 weeks) with exclusive breastfeeding, a control group 1 (average age 10.3 ± 3.3 weeks) exclusively fed with onset formula and a control group 2 (average age 56 ± 3.7 weeks) with infants that consumed gluten on a regular basis. The peptide 33-mer of gliadin was negative in all feces samples from both the experimental and control group 1. With regard to control group 2, the peptide 33-mer of gliadin was negative in 23% of cases (seven children). There was no difference in the amount of gluten ingested by these children compared to those who excreted the 33-mer peptide. Conclusions: the failure to detect gluten in the feces of infants that were exclusively breastfed indicates that it is probably below the limits of detection. Healthy children who consume gluten may not excrete it in feces

Non-IgE-mediated cow's milk allergy is a frequent disorder in paediatrics. As patients might be seen by professionals from different specialties and levels of expertise, a great variability in diagnostic procedures and disease monitoring is commonly observed. Therefore, four scientific societies involved in its management have developed a consensus document providing specific recommendations related to its prevention, diagnosis, treatment and follow up.
