Colonisation of the male reproductive tract in asymptomatic infertile men: Effects on semen quality.

The objective was to explore presence/detection of microorganisms in the male reproductive tract (PMMRT) in asymptomatic patients undergoing infertility treatment and their effects on semen quality in our region. This study enrolled 205 men (mean age, 35.9 years) in a single-centre, tertiary university hospital from December 2015 to December 2016. We used the modified Meares-Stamey test, real-time polymerase chain reaction (rt-PCR) and the National Institutes of Health Chronic Prostatitis Sympton Index (NHI-CPSI) questionnaire to address this issue. No patient met the prostatitis criteria by the modified Meares-Stamey 4-sample test, 33 (16.1%) were positive for rt-PCR in the first-voided urine for any of the Mycoplasma (Ureaplasma urealyticum/parvum, Mycoplasma hominis/genitalium) and C. trachomatis was detected in two cases (1%), and three for rt-PCR in semen for HPV high-risk genotypes non-16/18 (1.5%). Significant statistical differences were reported among patients with and without PMMRT in terms of lower rate of progressive spermatozoa (PR) (p < .034), total motile sperm count (p < .028), normal morphologic forms, especially in the sperm head (p < .001) and highest viscosity (p < .012). It was concluded that PMMRT, specially Mycoplasmas, in asymptomatic infertility men, affects semen quality. The NIH-CPSI questionnaire was not a valid initial screening to subsequently evaluate the presence of prostatitis/PMMRT.

Contaminación bacteriana en estetoscopios de las unidades de cuidados intensivos pediátricos: Hospital Central de San Cristóbal 2012 / Bacterial contamination of stethoscopes in pediatric intensive care units: Hospital Central de San Cristóbal 2012

Las infecciones adquiridas durante los cuidados de la salud (IACS), es un problema importante en Salud Pública. El presente trabajo tiene como objetivo determinar el porcentaje de estetoscopios contaminados con bacterias potencialmente productoras de IACS en las áreas de cuidados intensivos de pediatría y adultos. Se realizó un estudio clínico prospectivo transversal comparativo en la Unidades de Cuidados Intensivos pediátrico, neonatal y adulto del Hospital Central de San Cristóbal. Se tomaron cultivos a 37 instrumentos de los cuales 17 eran estetoscopios (52,9%). Nueve correspondieron a Pediatría y 8 al área de adulto. El tipo de personal que los utiliza representó un riego mayor de contaminación. De los estetoscopios con cultivos positivos el 85,6% venían de pediatría y el 36,4% de adultos; con una Odds ratio de 14.0. Conclusión: Los estetoscopios son una fuente de contaminación bacteriana siendo el área pediátrica un factor de riesgo elevado para su contaminación

Infections acquired during the (IACS) health care, is an important public health problem. This study aims to determine the percentage of stethoscopes contaminated with potentially producing bacteria of IACS in the areas of Pediatric and adult intensive care. A comparative study was conducted clinical prospective cross in the intensive care units paediatric, neonatal and adult of the Central Hospital of San Cristóbal. Cultures were taken at 37 instruments of which 17 (52,9%) were stethoscopes (9 corresponded to Pediatrics and 8 to the adult area). The type of personnel using it represented one major contamination risk. The stethoscopes with positive cultures the 85.6% came from Pediatrics and adults 36.4; with an Odds ratio of 14.0. Conclusion: Stethoscopes are a source of bacterial contamination being the Pediatric area a high risk of contamination of stethoscopes
