La presente investigación estudió el impacto de la enteroparasitosis en niños y analiza el papel de la educación sanitaria en la promoción de la salud en niños y familiares del Centro Educativo Inicial Estatal “Paz y Amor” de la Región Callao (Perú), durante el año 2017. El estudio se enmarca dentro de una investigación de tipo descriptivo transversal. La muestra estuvo conformada por 120 niños de 3 a 5 años, de los cuales se recolectaron muestras de heces fecales para conocer la prevalencia de parasitosis intestinal, se aplicó un instrumento de encuesta directa a los padres sobre las condiciones socioeconómicas. Así mismo se realizaron charlas educativas de promoción de la salud en la población de estudio antes y después de la recolección de muestras fecales. Para el análisis estadístico se utilizaron pruebas de chi cuadrado y técnicas descriptivas. Destacan como resultado la significancia estadística entre el número de niños en casa y el número de personas que duermen en cama (p<0.05) con presencia de parasitosis intestinal (Enterobius vermicularis).

El objetivo del presente estudio fue sintetizar el conocimiento existente referente a la presencia de Staphylococcus aureus resistente a meticilina en teléfonos celulares y en las fosas nasales de estudiantes y trabajadores del sector salud. El método que se empleó fue de enfoque cualitativo, utilizando la revisión sistemática de un total de 496 artículos, de los cuales se seleccionaron 22. Los resultados indican que existe una colonización nasal de Staphylococcus aureus resistente a meticilina en una proporción que oscila desde el 1.2% y el 11.1%. Se concluyó que este patógeno está presente en las fosas nasales mediante la infección directa durante el uso de teléfonos celulares en el entorno hospitalario y por la evidente falta de medidas de higiene y bioseguridad.

The aim of this study was to evaluate the inhibitory activity of the commercially available essential oils of Mentha spicata (spearmint) and Eucalyptus globulus (eucalyptus) on Streptococcus mutans ATCC 25175 biofilms in vitro, emulating dental plaque conditions. The composition of the essential oils (EOs) was determined using gas chromatography coupled with mass spectrometry (GC-MS), with the main metabolites being Carvone (57.93%) and Limonene (12.91%) for Mentha spicata and 1,8-Cineole (Eucalyptol) (65.83%) for Eucalyptus globulus. The inhibitory activity was evaluated using the methods of agar-well diffusion and colorimetric microdilution. The inhibition halos were 18.3 ± 0.47 mm and 27.0 ± 0.82 mm, and the MICs were 1.8484 mg/mL and 1.9168 mg/mL for the EOs of Mentha spicata and Eucalyptus globulus, respectively. The activity against the biofilms was evaluated on a substrate of bovine enamel pieces using a basal mucin medium (BMM) in anaerobic conditions with daily sucrose exposition cycles in order to emulate oral cavity conditions. The EOs were applied in a concentration of 0.5% in a sterile saline vehicle with 1% polysorbate 20. After 72 h of cultivation, a significant reduction was observed (p < 0.001%) on the biofilm biomass, which was evaluated by its turbidity in suspension and using a count of the recoverable organisms with regards to the control. The effects of the Eos were not significantly distinct from each other. The EOs showed antimicrobial activity against both the Streptococcus mutans planktonic and biofilm cultures. Thus, EOs may have great potential for the development of pharmaceutical and sanitary products for oral health.

Repetitive transcranial magnetic stimulation (rTMS) is a novel, non-invasive technique that uses electromagnetic force to alter neuronal excitability. The objective of this work is to carry out a brief but updated review of the basic principles of rTMS and to compare it with the principles of electroconvulsive therapy (ECT) in order to analyze its use and usefulness as an alternative method to ECT in Peru.

Magnetic resonance spectroscopy is the study of metabolites for the characterization of pathologies. These are of medical interest for the diagnosis and evolution of a patient through the analysis of the spectra, due to their importance, the present study has developed an effective methodology. Observing that of the 89 patients we obtain as a result that the MULTIVÓXEL technique is the most frequently used technique with 52.8% and the MONOVÓXEL technique the least frequent with 29.2%. In the tests it can be seen that the ICD-C71.0 classification is predominant with 14 cases. In addition, the highest percentage of N-Acetyl-Aspartate (NAA) is decreased 41.6%, 30.3% of patients have a normal NAA and 57.3% have elevated choline. Which allows us to conclude that the application of the method used was effective to guarantee the reliability of the reception of the sample spectrum.
