Variation in SARS-CoV-2 seroprevalence in children in the region of Asturias, Northern Spain.

Background: Updated seroprevalence estimates are important to describe the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) landscape and to guide public health decisions. The aims are to describe longitudinal changes in seroprevalence in children in a region in Northern Spain and to analyze factors associated with SARS-CoV-2 seropositivity.

Methods: Prospective multicenter longitudinal study with subjects recruited from July to September 2020.

Assessment of Two Nutritional Screening Tools in Hospitalized Children.

Aim: to evaluate validity and concordance of Screening Tool for the Assessment of Malnutrition in Pediatrics (STAMP) and Screening Tool for Risk On Nutritional status and Growth (STRONGkids) screening tools for assessment of nutritional risk in pediatric inpatients.

Methods: Prospective longitudinal observational multicenter study in children aged 1 month or older admitted as inpatients. Weight, height, cause of admission, demographic data, length of stay, and nutritional interventions were recorded.

[CPAP vs oxygen therapy in infants being transported due to acute respiratory failure].

Objective: The aims of our study are to evaluate the effectiveness and security of CPAP (continuous positive airway pressure) in infants transferred with acute respiratory failure (ARF) and to compare their evolution in PICU between CPAP vs oxygen therapy.

Materials And Methods: We conducted a retrospective observational and analytical study by reviewing the health records of infants with ARF aged 0 to 12months that required interhospital transfer to the PICU.

Results: We included 110 patients: 71 transported with CPAP and 39 with oxygen therapy.

Fecal Changes Following Introduction of Milk in Infants With Outgrowing Non-IgE Cow's Milk Protein Allergy Are Influenced by Previous Consumption of the Probiotic LGG.

Cow's milk protein allergy (CMPA) is the most common allergy in the first year of life. Non-IgE mediated CMPA is characterized by digestive symptoms and tolerance development before the age of three. Gut microbiota composition in early life has been associated with food allergy.

[Hypertrichosis cubiti in a girl with precocious puberty: Case report].

Hypertrichosis cubiti is a localized increase in hair density, length and thickness. It is an uncommon and benign entity with very few patients described in the medical literature (more or less than half a hundred). Half of the described patients associate other defects or malformations and the other half are purely aesthetic cases.

Microbiota and Derived Parameters in Fecal Samples of Infants with Non-IgE Cow's Milk Protein Allergy under a Restricted Diet.

Cow's milk protein allergy (CMPA) is the most common food allergy in infancy. Non-IgE mediated (NIM) forms are little studied and the responsible mechanisms of tolerance acquisition remain obscure. Our aim was to study the intestinal microbiota and related parameters in the fecal samples of infants with NIM-CMPA, to establish potential links between type of formula substitutes, microbiota, and desensitization.

[Variability of antibiotic treatment in paediatric acute pharyngotonsillitis in Asturias, Spain].

Introduction. Acute pharyngotonsillitis accounts for a large portion of antibiotic prescriptions in pediatric offces. Our aim was to analyze the antimicrobial prescription habits for acute pharyngotonsillitis in children from hospital emergency departments and primary care pediatric clinics in Asturias (Spain).

Low risk of bacteremia in otherwise healthy children presenting with fever and severe neutropenia.

We examined 785 placentas, including 51 from documented cases of congenital toxoplasmosis. Toxoplasma was detected in 16 placentas,including 1 in which congenital toxoplasmosis was ruled out. Placental screening had poor sensitivity (25%) but good specificity (99%), positive predictive value (93%), and negative predictive value (95%).
