Perinatal transmission of dengue virus in Puerto Rico: a case report  [PDF]
Janice Pérez-Padilla, Rafael Rosario-Casablanca, Luis Pérez-Cruz, Carmen Rivera-Dipini, Kay Marie Tomashek
Open Journal of Obstetrics and Gynecology (OJOG) , 2011, DOI: 10.4236/ojog.2011.13016
Abstract: We report a laboratory confirmed case of vertical transmission of dengue in a mother-child pair in the eastern part of Puerto Rico. The clinical course of the pregnant female suggested a GBS infection, but laboratory tests confirmed it was dengue infection, one week after delivery. The male infant was healthy at birth, but one week after birth developed clinical complications related to vertical transmission of dengue. This report targets physicians in dengue endemic countries like Puerto Rico to be aware of the possibility of vertical transmission of dengue in symptomatic pregnant patients, especially around the time of delivery.

III. La fisiología de Daniel Vergara Lope Escobar: Reinterpretación de algunos de sus datos
Pérez-Padilla, José Rogelio;
Gaceta médica de México , 2004,
Abstract: the mexican physiologist daniel vergara lope did research on medium-altitude physiology, mainly in mexico's central plateau, using several approaches. he described various mechanisms of adaptation to higher elevations that he felt protected people from a condition called barometric anoxyhemia. according to a french theory, this phenomenon occurred in the valley of mexico (and, generally, at higher elevations) and was deleterious for human survival and functioning, especially, with regard to intellectual capacity. the objective of this paper was to analyze dr. vergara lope's early published experimental data, especially that concerning respiratory capacity and frequency. the respiratory capacity he describes for 111 experimental subjects is slightly greater than that reported for the contemporary mexican population and reveals a broad dispersion that may indicate lack of precision in measuring. however, his data on respiratory frequency (22 per min) are considerably higher than those for normal subjects in mexico city and sherpa and aymar a populations living at elevations of 3000 to 4000 meters.

Menezes Ana Maria Baptista,Jardim José Roberto,Pérez-Padilla Rogelio,Camelier Aquiles
Cadernos de Saúde Pública , 2005,
Abstract: Chronic obstructive pulmonary disease (COPD) is now a major public health concern; deaths attributable to COPD in Latin America have increased by 65.0% in the last decade. This study was aimed at evaluating COPD prevalence and associated factors in adults (> 40 years) living in Greater Metropolitan S o Paulo, Brazil. The study is part of the Proyecto Latinoamericano de Investigación en Obstrucción Pulmonar (The PLATINO Project), a multi-center survey on COPD burden in Latin America, with S o Paulo as the first center where the project has been carried out. A population-based sample was selected in multiple stages. Spirometry tests were performed in each subject pre- and post-bronchodilator and COPD was mainly defined as the ratio of forced expiratory volume to forced vital capacity below 70.0% (fixed ratio definition). Other spirometric criteria were also used for the diagnosis of COPD. COPD prevalence was 15.8% (95%CI: 13.5-18.1) using the fixed ratio definition. COPD was positively associated with age and smoking and inversely with body mass index. Utilization of different COPD spirometry criteria resulted in different percentages of COPD, but similar associated factors.

Abstract: objective: to describe the tuberculosis morbidity and mortality trends in mexico, by comparing the data reported by the ministry of health (mh) and the world health organization (who) between 1981 and 1998. material and methods: the number of cases notified in the past few years, their rates, and the trends of the disease in mexico were analyzed. the incidence of smear-positive pulmonary tuberculosis was estimated for 1997 and 1998 with the annual tuberculosis infection risk (atir), to estimate the percentage of bacilliferous cases in 1997-1998. results: who reported more tuberculosis cases for mexico than the mh. however, this difference has decreased throughout the years. the notification of smear-positive cases remained stable during 1993-1998. the estimated percentages of detection were 66% for 1997 and 26% for 1998 (based on atir of 0.5%). tuberculosis mortality decreased gradually (6.7% per year) between 1990 and 1998, whereas the number of new cases increased, suggesting the persistence of disease transmission in the population. conclusions: inconsistencies between case notifications from national data and who were considerable, but decreased progressively during the study period. according to atir estimations, a considerable number of infectious tuberculosis cases are not detected.

Abstract: objective: to decribe spirometric function and adjustment to foreign prediction equations in mexican workers claiming work related disability. material and methods: we reviewed 5771 spirometries done at the mexican national institute of respiratory diseases performed with equipment and methods proposed by the american thoracic society. with the spirometries we generated multiple regression equations separated for men and women based on age and height, compared to other in common use reported by knudson and hankinson in north america and by quanjer in europeans. results: 80% of the tests were reproducible for fvc and fev1 according to ats, wheras 10% were reproducible for neither. mean fvc in men was 12% above values reported by quanjer, 22% above knudson, 3% above hankinson and 6% above rodriguez-reynaga, whereas similar values for women were 18%, 10%, 0% and 1%. excluding obese and those who had less than 2 acceptable maneuvers, the numbers increase by 1-2%. fev1 was also above predicted. conclusions: most workers requesting disability are able to generate a reproducible spirometry. however for the same gender, age and height, workers had a fev1 and a fvc above normal values reported by knudson and quanjer and are more similar to those reported by hankinson in mexican-americans. while a set of appropiate reference values are obtained, regression equations obtained from the studied group will generate less error in the evaluation of disability in mexican workers.the english version of this paper is available at: http://www.insp.mx/salud/index.html

Abstract: OBJETIVO: Describir las tendencias de la morbilidad y mortalidad de la tuberculosis en México, entre 1981 y 1998, comparando datos de la Secretaría de Salud y de la Organización Mundial de la Salud. MATERIAL Y MéTODOS: Se analizó el número de casos y tasas notificados y la tendencia de la enfermedad en los últimos a os. Se calculó la incidencia de casos nuevos de tuberculosis bacilíferos mediante el riesgo anual de infección tuberculosa, con lo que se estimó el porcentaje de detección de casos bacilíferos en 1997-1998. RESULTADOS: El número de casos de tuberculosis emitido por la Organización Mundial de la Salud supera al notificado por la Secretaría de Salud, discrepancia que se ha reducido. Los casos bacilíferos se han mantenido entre 1993-1998 y se estimó una detección de 66 y de 26% en 1997 y 1998, respectivamente (para un Riesgo Anual de Infección Tuberculosa de 0.5%). La mortalidad se redujo 6.7% cada a o entre 1990 y 1998 mientras que se observó un aumento de casos nuevos, lo que implica la persistencia de la transmisión de la infección entre la población. CONCLUSIONES: Hay discrepancia entre el número de casos de tuberculosis ofrecido por la Secretaría de Salud y la Organización Mundial de la Salud. De acuerdo con las estimaciones por el Riesgo Anual de Infección Tuberculosa se deja de detectar un número considerable de casos bacilíferos.
Reproducibilidad de espirometrías en trabajadores mexicanos y valores de referencia internacionales

Salud Pública de México , 2001,
Abstract: OBJETIVO: Analizar la reproducibilidad de las espirometrías en un grupo de trabajadores mexicanos que demandaban incapacidad, así como determinar qué tan apropiados son los valores de referencia internacionales cuando se aplican en población mexicana. MATERIAL Y MéTODOS: Se estudiaron 5 771 espirometrías realizadas en el Instituto Nacional de Enfermedades Respiratorias de México con equipo y métodos recomendados por la Sociedad Americana del Tórax (ATS, por sus siglas en inglés). Del total de espirometrías, 685 se practicaron en mujeres. Se generaron ecuaciones de regresión múltiple para hombres y mujeres con base en edad y talla, y se les comparó con las notificadas para población estadunidense por Knudson y Hankinson, para europeos, por Quanjer, y para mexicanos, por Rodríguez Reynaga. RESULTADOS: El 80% de las pruebas realizadas llenaban los criterios de reproducibilidad propuestos por la ATS, tanto para la capacidad vital forzada (FVC) como para el volumen espiratorio forzado en el primer segundo (FEV1), mientras que 10% de ellas no mostraron reproducibilidad para ninguna de las dos mediciones. Los hombres estudiados mostraron en promedio una FVC 12% por arriba del estándar de Quanjer, 22% por encima del de Knudson, 3% por arriba del de Hankinson y 6% superior al de Rodríguez Reynaga, mientras que las mujeres arrojaron porcentajes de 18, 10, 0 y 1%, respectivamente. Excluyendo a obesos y a los que no realizaron dos esfuerzos aceptables, los valores se incrementaban en 1 a 2%. El FEV1 tuvo un comportamiento similar. CONCLUSIONES: Las espirometrías de un alto porcentaje de trabajadores que demandan incapacidad, son reproducibles. Tienen, para la misma talla, edad y género, un FEV1 y una FVC mayores que los notificados por Knudson en Estados Unidos de América y por Quanjer en Europa, aunque similares a los encontrados por Hankinson en méxicoamericanos. Mientras se obtienen valores de referencia confiables, las ecuaciones de regresión del grupo estudiado producen menos errores en la determinación de incapacidad en México.
