to be from 2.5 to 5.5 cases per 1,000 catheter-day. the clinical impact is relevant and increases the cost of the HD Unit. Methods: The present study is the irst of 2 phases. It was conducted from January to December of 2012, and included all patients and nurses who were in the HD Unit. The prevalence of Gramnegative bacilli (GNB) and methicillin-resistant Staphylococcus aureus (MrSA) colonizing the nasal passages and the skin is described. Also, phenotypic association was sought by genus, species and sensitivities between colonizing bacterial strains and blood cultures with GNB and MRSA. Results: the study included 70 patients and 10 nurses. the prevalence of nasal colonization in patients by GNB was 9% and 6% in the pericatheter, and no nursing GNB colonization was discovered. The prevalence of MRSA nasal colonization was 19% and 6% in the pericatheter for patients and in the nurses the nasal colonization was 50% and 10% in the hands. We identiied 29 cases of primary bacteremia. The primary bacteremia rate is 1.5 per 1,000 catheter-day or 0.4 episodes per patient per year. Conclusion: We demonstrated a high prevalence of MrSA colonization in patients and nurses in the HD Unit. No relationship was found between primary bacteremia by GNB and patients and nurses’ bacteria colonization by the phenotypic comparison.

Brain abscesses can cause an incapacitating neurological deicit in up to 50% of patients, thus the reduction of these sequelae becomes the main goal of its timely and speciic surgical and medical treatment. With technological advances in bacteriological identiication and diagnostic imaging, the clinical suspicion can be conirmed, and the speciic etiological agent can be identiied in a larger number of cases. New pathogens have emerged through this process, such as Streptococcus porcinus, in which the ability to affect the central nervous system has not been documented. A clinical case is presented of a brain abscess in an immunocompetent patient, and its favorable response to surgical drainage t hrough a skull burr h ole and nee dle aspiration with antibiotic therapy (ceftriaxone, metronidazole and vancomycin) is discussed.

Introduction: Hospital malnutrition risk has prevalence values of 20%-50%, and it is a major health problem in the health institutions worldwide. Objective: To assess the accomplishment of nutritional screening and the prevalence of hospital malnutrition risk in a University Hospital. Materials and methods: A retrospective analysis was carried out with nutritional screening, using primary data from six clinical areas obtained in the period between July 2012 and December 2013. According to previous results in Mexican health institutions and considering a mean malnutrition risk prevalence of 50%, it was calculated that a sample size of 3200 subjects was required for the assessment of valid risk values. Patients with values ≥3 on the Nutritional Risk Screening (NRS, 2002) were classiied as carriers of nutritional risk. Results: A total of 5611 patients (38% of all patients admitted) were studied. The rate of screening declined from 55% in 2012 to 31% in 2013. During the whole period, 3034 patients were classiied with risk of malnutrition (54% prevalence). Conclusions: The prevalence of hospital malnutrition risk was high. The accomplishment of the nutritional screening was deicient, and declined between 2012 and 2013. The lack of nutritional screening does not meet the vital care requirements of hospitalized patients and prevents the timely treatment of those at malnutrition risk.

Ebola virus disease was irst described in 1976 originating from the Ebola River in the Democratic Republic of Congo. Since then, Ebola virus has become an important public health threat in Africa, and now it is of great concern worldwide due to the recent outbreaks (9216 cases with 4555 deaths up to October 20th, 2014), and it is so far the largest and deadliest recorded in history. Five Ebola virus species have been identiied (including Zaire, Sudan, Ivory Coast, Reston, and Bundibugyo Ebola virus), and four of them have proved to be highly pathogenic for both human and non-human primates, causing viral hemorrhagic fever with case fatality rates of up to 90%, for which no approved therapeutics or vaccines are currently available. Ebola virus infections are characterized by immune suppression and a systemic inlammatory response that causes impairment of the vascular, coagulation, and immune systems, leading to multiorgan failure and shock, and thus, in some ways, resembling septic shock. The major affected countries, Sierra Leone, Guinea, Liberia, and Nigeria, have been struggling to contain and to mitigate the outbreak. Gene sequencing of the 2014 virus (2014WA) outbreak has demonstrated 98% homology with the Zaire Ebola virus, with a 49% case fatality ratio across the affected countries. In this review the characteristics of the viruses, pathogenesis, diagnosis, treatment, and the cases reported in health care workers (HCW) are described, as well as a summary of outbreaks of the virus since its discovery, including these last two outbreaks in Africa.

An alarming rise of obesity in adolescents has been observed, placing them at risk of developing resistance to insulin (IR) and its adverse metabolic consequences such as diabetes mellitus type 2 (DM2), metabolic syndrome and cardiovascular disease. Objective: To know the prevalence of obesity, and the levels of glucose, insulin and HOMA-IR and its association with the BMIz, waist circumference and the pubertal stage in a random sample of adolescents. Materials and methods: 292 adolescents between 12 and 15 years (152 female and 140 male), whose anthropometric measurements (weight, height and waist circumference) were taken, body mass index calculated and Z-score determined. Blood glucose and insulin levels were evaluated from a sample of blood and their HOMA-IR was determined. Results: The results showed that 32.5% were obese, 22.3% were overweight and 23.6% showed adolescent central obesity. Glucose levels (p = 0.016), insulin (p = 0.0001) and HOMA-IR (p = 0.0001) showed significant differences in the group with obesity. Values of the three parameters were increased with the stage of puberty. We found significant differences in the levels of glucose (p = 0.0388), insulin (p = 0.0005) and HOMA-IR (p = 0.0001) between the prepubertal and postpubertal stages.

Se realiza un estudio clínico descriptivo con el fin de determinar los principales factores de riesgo para Enfermedad Pulmonar Obstructiva Crónica [EPOC] en los pacientes ingresados en el servicio de clínica del Hospital Vicente Corral Moscoso [HVCM]. Se estudian 106 casos de pacientes con diagnóstico de EPOC ingresados en el servicio de clínica del HVCM en 5 años de estudio [1990-1994] comparándolos con un grupo igual numericamente de pacientes que no presentaron sintomatología respiratoria. Se establece que el único factor de riesgo estadísticamente significativo entre los dos grupos es la presencia de infecciones respiratorias repetitivas. Los demás factores de riego [tabaquismo, exposición a polvos orgánico e inorgánicos, exposición a humos y reacciones alérgicas] no tienen resultados estadísticamente significativos al comprar los dos grupos objeto de la presente investigación. Se presentan las conclusiones pertientes, las sugerencias respectivas y se adjunta la referencia bilbiográfica actualizada

Se realiza un estudio clínico descriptivo en 210 personas asintomáticas voluntarias, con el fin de establecer la prevalencia por grupos etáreos de la infección por H. Pylori en personas asintomáticas entre los 10 y 80 años a través de la determinación de IgG, por el método de ELISA en suero sanguíneo. Se clasifican a los individuos de acuerdo a si presentan o no factores de riesgo, principalmente hacinamiento, en el aseo de manos, higiene bucal y convivencia con animales domésticos. Se concluye que la prevalencia de resultados positivos es del 63.3 por ciento en el examen serológico y es mayor sobre los 40 años sin que exista diferencia de sexo, siendo los principales factores de riesgo la convivencia con el gato y el cepillado dental no adecuado. En los pacientes con prueba serológica positiva a los que se realizó la endoscopía [40], se encontró un resultado histopatológico con reporte de gastritis aguda en el 42.5 por ciento y de gastritis crónica en el 30 por ciento; la positividad de H. pylori histopatológicamente fue del 52.5 por ciento. Las pruebas de sensiblidad de la ureasa y de la IGG fueron del 90.47 por ciento y del 95.2 por ciento, respectivamente y la especificidad de 84.2 en ambas pruebas
