Abstract: Objective: To investigate maternal and neonatal complications resulting from inadvertent immunization against rubella-measles during the first trimester of pregnancy. Methods: A prospective and descriptive study was carried out, including a total of 1,924 pregnant women, 175 (9.1%) of which were classified as non responding to infection by the rubella virus. They underwent clinical and ultrasonographic follow-up to dismiss maternal or fetal complications and complications at the time of delivery. The infant was checked to determine demographic, anthropometric, serological and clinical features at the time of birth. Results: No women had complications during the pregnancy, including exanthematic symptoms. 174/175 newborns were studied; one pregnancy was interrupted based on non-medical arguments. The findings in terms of the analyzed patients suggest a benign evolution after inadvertently immunizing the pregnant women, which support studies with similar results. No complications during the course of the pregnancy or phenotypic alterations of the infant at the time of birth are suggested.

Abstract: introduction. the autopsy has been recognized as a useful tool for medical education and for quality improvement, evaluating therapeutic and diagnostic measures. in the last 50 years, the autopsy rates have constantly declined. interestingly, between 1972 and 2002, the discrepancies between clinical diagnoses and autopsy findings haven't diminished, even with all the technological improvements now available. this research enables us to determine the discrepancy rate between our clinical diagnosis and autopsy results, as well as the main diseases that need diagnostic or therapeutic improvements in our hospital. our objectives were: 1. to obtain the discrepancy rate between clinical diagnoses and autopsy findings. 2. to determine the most frequent type of discrepancy, according with the goldman criteria, modified by battle, and 3. to evaluate the possible association of these discrepancies with the number of admissions, length of stay, patient's age and physician's age. material and methods. a retrospective, observational, comparative and transversal study. sample: all cases that had an autopsy between january 1st and december 31th 2004. cases with an incomplete record were excluded. the main variables analyzed were: age, gender, number of admissions and their length of stay, main clinical service, type of autopsy, main clinical and autopsy diagnoses and probable cause of death. results. in the year 2004 there were 209 deaths registered with 62 autopsies (29.7% rate). we found a discrepancy in the main clinical diagnosis in 15 cases (24.6%); and, according with the goldman criteria, modified by battle, we found a class i discrepancy in 5 cases (8.2%) and a class ii discrepancy in 4 cases (6.6%). we didn't find significant statistical differences in patients older than a year compared with patients less than 1 year old. there were no significant differences regarding the number of admissions and their length of stay, or variations the artendiag with the attending physi

Abstract: objective. to describe the occurrence of hemorrhagic disease of the newborn (hdn) at a tertiary care pediatric hospital of morelos state. material and methods. a retrospective case series study was conducted between 1997-2000 at hospital del ni?o morelense (morelos state children's hospital), in 46 newborns aged under 12 weeks. study subjects were referred from peripheral units with a diagnosis of hdn. results. the severe late-onset form of hdn was present in 91% of the cases. fifty-two percent of childbirths were assisted by a physician and 48% by an empiric midwife. application of vitamin k was unknown in 61% of cases, in 39% it was not applied and in 4% it was applied. the majority of infants presented severe symptoms due to intra-cranial bleeding, 11% died, and 41% had severe disease sequelae. conclusions. given the high prevalence of hdn in the state of morelos, reproductive health programs should be reviewed and training programs intensified to promote the utilization of vitamin k by physicians and nurses for preventing this disease.

Abstract: OBJETIVO: Evaluar los niveles de plomo en sangre de ni os morelenses y sus factores de exposición. MATERIAL Y MéTODOS: Estudio transversal para analizar, por voltametría anódica, los niveles de plomo en sangre de 232 ni os de 1 a 12 a os de edad, que acudieron de junio a octubre de 1996 al Hospital del Ni o Morelense de Cuernavaca, Morelos, México. Los factores de exposición se indagaron por cuestionario. El valor de concentración de plomo se transformó al logaritmo natural; se estimó la razón de momios para algunos factores de exposición que se incorporaron a un modelo de ANOVA. RESULTADOS: Se reclutaron 232 ni os (50% mujeres); 73% residentes en Cuernavaca. La media geométrica de plomo en sangre fue 6.7 μg/dl; 29.7% rebasaron los 10 μg/dl; 66% tenían antecedente de cocinar alimentos en barro vidriado; 36% de almacenar alimentos, y 19%, consumo de líquidos en ese material. CONCLUSIONES: Los niveles encontrados son similares a los reportados en otras poblaciones pediátricas mexicanas en los últimos a os. Entre los principales factores de exposición destacan el uso de barro vidriado para consumo de alimentos o líquidos y la intensidad del tráfico donde viven. Este es el primer estudio que documenta los niveles de plomo en sangre en población infantil de Morelos, México, y sus resultados son punto de partida para acciones futuras de control y prevención.

Abstract: Objetivo. Describir la experiencia con enfermedad hemorrágica del recién nacido en un hospital pediátrico del tercer nivel de atención. Material y métodos. Estudio retrospectivo efectuado en el Hospital del Ni o Morelense de la ciudad de Cuernavaca, estado de Morelos, México, durante el periodo 1997-2000, con una muestra de 46 neonatos, afectados de enfermedad hemorrágica del recién nacido (EHRN), referidos de poblaciones de la periferia del estado. Resultados. De los pacientes, 91% presentó la forma tardía grave de EHRN. El 52% de los partos fueron atendidos por médico y 48% por parteras. Se desconoce aplicación de vitamina K en 61%, en 35% no fue aplicada y en 4% sí se aplicó. La mayoría presentó sintomatología severa secundaria a hemorragia intracraneana. Hubo defunción en 11% y secuelas severas en 41%. Conclusiones. La EHRN es un problema frecuente en el estado de Morelos y, por ello, se requiere analizar los programas de salud reproductiva e intensificar la capacitación de médicos y enfermeras sobre la prevención de ésta mediante el uso de vitamina K.

A base-point-free definition of the Lefschetz invariant
Vesta Coufal
Fixed Point Theory and Applications , 2006,
Abstract: In classical Lefschetz-Nielsen theory, one defines the Lefschetz invariant L( f ) of an endomorphism f of a manifold M . The definition depends on the fundamental group of M , and hence on choosing a base point ∈M and a base path from to f( ) . At times, it is inconvenient or impossible to make these choices. In this paper, we use the fundamental groupoid to define a base-point-free version of the Lefschetz invariant.

Abstract: In classical Lefschetz-Nielsen theory, one defines the Lefschetz invariant L(f) of an endomorphism f of a manifold M. The definition depends on the fundamental group of M, and hence on choosing a base point ¢ — ¢ M and a base path from ¢ — to f( ¢ —). At times, it is inconvenient or impossible to make these choices. In this paper, we use the fundamental groupoid to define a base-point-free version of the Lefschetz invariant.
