Abstract
Antecedentes El cáncer de laringe representa el 21.7% de las neoplasias malignas de vías aerodigestivas superiores. La prevalencia del virus del papiloma humano (VPH) en el cáncer de laringe oscila entre el 0 y el 80%. Método Se incluyeron 112 muestras de tejido laríngeo de pacientes con cáncer de laringe. Se amplificó el ADN y se analizó la presencia y el genotipo del VPH mediante hibridación reversa (INNO-LiPA®). Se realizaron pruebas de ji cuadrada, Fisher y t de Student no pareada. Resultados Se incluyeron muestras de 107 hombres (95.5%) y 5 mujeres (4.5%), con una edad de 65.3 ± 10.1 años, con antecedente de tabaquismo 108 (96.4%), alcoholismo 9 (8.0%) y carcinoma epidermoide moderadamente diferenciado queratinizante 96 (85.7%). Se identificó VPH en 60 (53.5%), VPH-11 en 51 (45.5%), VPH-52 en 27 (24.1%), VPH-16 en 9 (8.0%), VPH-45 en 3 (2.6%) y coinfección por más de un genotipo en 31 (27.6%). No hubo diferencia entre pacientes con y sin infección por VPH en cuanto a edad, sexo, localización, diagnóstico histopatológico, tabaquismo ni alcoholismo (p > 0.05). Conclusiones La prevalencia de infección por VPH en el cáncer de laringe fue del 53.5%, con coinfección por más de un genotipo en el 27.6%. El genotipo más frecuente fue el VPH-11, tipo de bajo riesgo, seguido por el VPH-52, de alto riesgo oncogénico. Background Laryngeal cancer represents 21.7% of malignancies of the upper aerodigestive tract. The prevalence of the Human Papillomavirus (HPV) in laryngeal cancer ranges 0 to 80%. Methods We included 112 laryngeal tissue samples obtained from patients with laryngeal cancer. DNA was extracted and amplified by PCR. HPV presence and genotype were analyzed by the reverse hybridization INNO-LiPA® assay. Chi-square, Fisher’s and unpaired Student t tests were used. Results Samples from 107 male (95.5%) and 5 female patients (4.5%) were evaluated, aged 65.3±10.1 years, 108 with smoking history (96.4%), 9 with alcoholism history (8.0%), and in 96 the histological diagnosis was moderately differentiated keratinizing squamous cell carcinoma (85.7%). HPV was detected in 60 samples (53.5%), HPV-11 in 51 (45.5%), HPV-52 in 27 (24.1%), HPV-16 in 9 (8.0%), HPV-45 in 3 (2.6%), and coinfection by more than one genotype in 31 (27.6%). There was no difference between patients with and without HPV infection with respect to age, sex, tumor location and histology, smoking and alcoholism history (p>0.05). Conclusions The prevalence of HPV infection in laryngeal cancer was 53.5% with coinfection with more than one genotype in 27.6%. The most frequent genotype was HPV-11, an oncogenic low-risk genotype, followed by HPV-52, a high-risk genotype.

Abstract
Objective To evaluate the knowledge and attitude towards organ donation of medicine students of a Northwestern Mexico public university. Materials and Methods A prolective, descriptive, observational, and cross-sectional study. A 34 items cross-sectional survey evaluating knowledge and attitude towards organ donation in 3,056 medicine students during 2013-2015. Descriptive statistics were used as absolute frequencies, percentages, mean and standard deviation, as well as the Chi-square test. A p < 0.05 was considered significant. Results 74% of students would donate their own organs, mainly due to reciprocity (41%). 26% of students would not donate, 48% of them because of fear that their organs could be taken before death. 86% would donate organs from a relative. 64% have spoken about organ donation and transplantation with their family and 67% with friends. 50% said they had received no information about it. 68% understand the concept of brain death. Conclusion Students received little information about organ donation during college. Despite that, most of them showed a positive attitude and are willing to donate.

Abstract
Group B streptococci (Streptococcus agalactiae) cause a number of infections in women during pregnancy and postpartum, such as urinary tract infection, chorioamnionitis and endometritis, consequently may affect the newborn. Group B streptococci is the most common cause of severe infections in newborns in developed countries. Studies on the epidemiology of group B streptococci infections in Latin America are still limited. This information is also unknown in Mexico, but studies carried out in the center of the country have found high rates of vaginal colonization in pregnant women and there are case series and case reports of newborns. Microbiological and molecular epidemiology studies in Mexico have shown that populations of group B streptococci have a clonal distribution and that there are clones with genetic and phenotypic characteristics of high virulence that appear to be responsible for most of perinatal pathology. However, the actual role of group B streptococci in perinatal pathology in Mexico is unknown. Consequently, whether to perform or not the screening for determining the group B streptococci colonization status in pregnant women, and the indication or not for intrapartum antibiotic prophylaxis to prevent neonatal group B streptococci infection in Mexico, are still controversial.

Abstract
BACKGROUND Improper use of antibiotics increases antimicrobial resistance. OBJECTIVE Evaluate the use of antibiotics and the impact of an intervention designed to improve antibiotic prescription for surgical prophylaxis in 6 hospitals of Monterrey, Mexico. MATERIAL AND METHODS Design: A prospective multicenter survey and a pretest-postest experimental study. Phase 1: Survey to evaluate the use of antibiotics through an especially designed guide. Phase 2: Intervention designed to improve antibiotic prescription for surgical prophylaxis by the medical staff by using printed, audiovisual and electronic messages. Phase 3: Survey to evaluate the impact of the intervention. ANALYSIS Frequencies, percentages, medians, ranges and X2 test. RESULTS Phase 1: We evaluated 358 surgical patients, 274 prophylactic antibiotic regimens. A total of 96% of antibiotics regimens began with inappropriate timing (290/302), 82.8% were inappropriate regimens (274/331), 77.7% were in inappropriate dosage (230/296), 86% of inadequate length (241/280), and in 17.4% restricted antibiotics were used (52/299). Phase 2: 9 sessions including 189 physicians (14 department chairs, 58 general practitioners and 117 residents). Phase 3: We evaluated 303 surgical patients, 218 prophylactic antibiotics regimens. Inappropriate treatment commencement was reduced to 84.1% (180/214) (P<0.001), inappropriate regimens to 75.3% (162/215) (P=0.03), inappropriate dosages to 51.2% (110/215) (P<0.001), and use of restricted antibiotics to 8.3% (18/215) (P=0.003). CONCLUSIONS Inappropriate use of prophylactic antibiotics in surgery is a frequent problem in Monterrey. The intervention improved the antibiotic prescription for surgical prophylaxis by reducing inappropriate treatment commencement, regimens, dosages, and overuse of restricted antibiotics. It is necessary to strengthen strategies to improve the prescription of antibiotics in surgical prophylaxis.
