Introduction: Traumatic brain injury (TBI) is an important pathology in pediatrics due to its frequency and the associated care burden to managing the derivate consequences.
Target: To determinate the epidemiological characteristics of TBI patients treated in the Pediatric Emergency Service of the new "río Hortega" Hospital of Valladolid, after the recent establishment of a new TBI management protocol.
Material and methods: We carried out a longitudinal observational descriptive study which included 127 patients, over a period of six months, who had been diagnosed with TBI, taking the data from a predefined questionnaire.
Results: The average age of the patients was 3.13 years, mostly male (55.9%). The most common cause was the accidental fall. The clinical appearance is more frequent in children older than two years. Most of the cases were classified as mild (94.5%). Only four hospital admissions were prescribed. No deaths were recorded. The CT was performed in 8.9% of the cases.
Conclusion: The results obtained in this study are similar to the one found in the bibliography. Although we get a lower mortality and morbidity rate and a minor indication of diagnostic tests. Initial neurological exploration and the calculation of the Glasgow Score are still the main tools to set the priority in its therapeutic management and prognosis.

During lactation, the physiological mammary microbiotas characterized by the presence of a relatively heterogeneous population, dominated by certain Gram-positive bacteria, at a moderated concentration (< 1,000 CFU/mL milk). However, there are circumstances that may lead to a disbiotic process of the mammary gland microbiota, leading to mastitis. This is a widely underrated condition, partly due to the absence of uniform protocols for the collection of this biological fluid, the lack of tradition in microbiological analysis of human milk, and the doubts that sometimes arise when the results interpretation is being done. In this article, we present a basic protocol for the collection of human milk samples for their microbiological analysis and simple guidelines in order to facilitate the interpretation of the results.
