Inside the Outbreak of the 2009 Influenza A (H1N1)v Virus in Mexico

Influenza viruses pose a threat to human health because of their potential to cause global disease. Between mid March and mid April a pandemic influenza A virus emerged in Mexico. This report details 202 cases of infection of humans with the 2009 influenza A virus (H1N1)v which occurred in Mexico City as well as the spread of the virus throughout the entire country.From May 1st to May 5th nasopharyngeal swabs, derived from 751 patients, were collected at 220 outpatient clinics and 28 hospitals distributed throughout Mexico City. Analysis of samples using real time RT-PCR revealed that 202 patients out of the 751 subjects (26.9%) were confirmed to be infected with the new virus. All confirmed cases of human infection with the strain influenza (H1N1)v suffered respiratory symptoms. The greatest number of confirmed cases during the outbreak of the 2009 influenza A (H1N1)v were seen in neighbourhoods on the northeast side of Mexico City including Iztapalapa, Gustavo A. Madero, Iztacalco, and Tlahuac which are the most populated areas in Mexico City. Using these data, together with data reported by the Mexican Secretariat of Health (MSH) to date, we plot the course of influenza (H1N1)v activity throughout Mexico.Our data, which is backed up by MSH data, show that the greatest numbers of the 2009 influenza A (H1N1) cases were seen in the most populated areas. We speculate on conditions in Mexico which may have sparked this flu pandemic, the first in 41 years. We accept the hypothesis that high population density and a mass gathering which took in Iztapalapa contributed to the rapid spread of the disease which developed in three peaks of activity throughout the Country

Reconstrucción mamaria postmastectomía. Análisis y resultados en un hospital de tercer nivel en México

Resumen Introducción y Objetivo El tratamiento de las neoplasias mamarias así como de ciertos padecimientos benignos requieren, en muchos casos, una mastectomía unilateral o bilateral con resección de la piel, glándula mamaria y complejo pezón-areola. La reconstrucción mamaria es una parte importante del tratamiento multidisciplinario para lograr la reintegración de las mujeres a una vida normal. El objetivo de nuestro estudio fue reportar los resultados de los diferentes tipos de reconstrucción mamaria en pacientes con cáncer de mama, así como otros padecimientos benignos, en un hospital de alta especialidad del Occidente de México. Material y Método Serie de casos en la que incluimos pacientes sometidas a reconstrucción mamaria entre el 1 enero de 2006 y el 31 de diciembre de 2012 con diferentes procedimientos, evaluando el tipo de cirugía inicial, tipo de reconstrucción, procedimientos complementarios y morbilidad. El seguimiento de las pacientes fue de 24 meses. Resultados Recogimos 170 pacientes con un promedio de edad de 46.12 ± 8.2 años. Las técnicas más utilizadas fueron: reconstrucción con implante expansor tipo Becker (48.8%), expansor tisular (11.2%), colgajo miocutáneo de recto abdominal transverso (8.8%), implantes definitivos (8.8%) y reconstrucción con dorsal ancho más implante o expansor (8.8%). Se presentaron complicaciones en 20 pacientes (11.8%). Conclusiones Nuestros resultados son satisfactorios ya que la morbilidad temprana y tardía son aceptables, pero, perfectibles. Con el advenimiento de extensas campañas de detección oportuna esperamos aumentar los procedimientos conservadores por cirugía temprana y los procedimientos oncoplásticos durante la mastectomía sin necesidad de esperar periodos prolon-gados para la reconstrucción

Experimental and Theoretical Studies on Acid Corrosion Inhibition of API 5L X70 Steel with Novel 1-N-α-d-Glucopyranosyl-1H-1,2,3-Triazole Xanthines

A series of novel 1-N-α-d-glucopyranosyl-1H-1,2,3-triazole xanthines was synthesized from azido sugars (glucose, galactose, and lactose) and propargyl xanthines (theophylline and theobromine) using a typical copper (I)-catalyzed azide–alkyne 1,3-dipolar cycloaddition. The corrosion inhibition activities of these new carbohydrate-xanthine compounds were evaluated by studying the corrosion of API 5 L X70 steel in a 1 M HCl medium. The results showed that, at 10 ppm, a 90% inhibition efficiency was reached by electrochemical impedance spectroscopy. The inhibitory efficiency of these molecules is explained by means of quantum chemical calculations of the protonated species with the solvent effect, which seems to better represent the actual situation of the experimental conditions. Some quantum chemical parameters were analyzed to characterize the inhibition performance of the tested molecules
