Factores de riesgo de la cardiomiopatía periparto : revisión sistemática

La cardiomiopatía periparto se considera como la primera causa de muerte de origen cardiaco en pacientes obstétricas y cerca de la mitad de ellas pueden evolucionar al deterioro hemodinámico. El objetivo del estudio fue realizar una revisión sistemática sintetizando información sobre factores de riesgo para la CMPP en mujeres entre el último mes de embarazo y los cinco primeros meses post-parto. Metodología: Búsqueda sistemática de la literatura evaluando calidad metodológica que proporcionara evidencia sobre factores de riesgo para CMPP. Resultados: Cuatro artículos cumplieron con los criterios de inclusión. La hipertensión arterial, la edad, la multiparidad y la raza (afrodescendiente) fueron reportados como factores de riesgo. Otros factores como la ingesta de agua de rio, el estado civil (soltera), la escolaridad y los ingresos económicos bajos se presentaron con una fuerte asociación en solo uno de los estudios. Discusión: La CMPP es una patología que aunque presenta incidencia baja posee alta tasa de complicaciones y mortalidad. Pocos artículos evalúan con adecuada metodología la etiología y factores de riesgo de la CMPP ya que incluyen diferentes variables y poblaciones aunque la mayoría de ellos se han centrado en la población afrodescendiente ya que en ella se han reportado tasas de incidencia más altas de la enfermedad. Conclusión: Es necesario estudios con diseños que permitan unificar la información y aclarar el papel de factores clásicos y emergentes en la presentación de la CMPP

Situación de la salud materno-perinatal en 2 Centros de Salud de Bizkaia

Introducción: La salud reproductiva y, en concreto, todos los aspectos relacionados con los cuidados de salud durante el embarazo, son temas de especial relevancia, tanto para la sociedad como para los servicios sanitarios. De modo que es necesario asegurar una adecuada atención de la mujer durante el embarazo, parto y postparto. Objetivo: Analizar y determinar la satisfacción de las mujeres con el seguimiento de su embarazo (gestación, parto y postparto) y comparar las diferencias existentes entre los 2 Centros de Salud (C.S) en los que se ha realizado dicho seguimiento. Metodología: Se realizó un estudio a 32 mujeres atendidas en los C.S. de Bombero-Etxaniz y Arrigorriaga, en el periodo transcurrido entre el 15 de enero del 2013 y el 15 de marzo del 2013; las encuestas se llevaron a cabo en el primer trimestre postparto. Se desarrolló un análisis descriptivo de los datos y un estudio de asociación entre las diferentes variables. Resultados: La media de edad de las mujeres estudiadas se situó en 34,75; se encontró asociación entre la edad y los embarazos de riesgo. El 50% de los partos fueron eutócicos; se estableció relación con la edad y la paridad. A más del 50% de ellas se les realizó una episiotomía, buscando una relación con el hospital se halló que cuanto más grande era el hospital más episiotomías se realizaban. Así mismo las encuestadas mostraron una mayor satisfacción con la atención prestada por los centros hospitalarios privados; en referencia a los C.S. no se hallaron diferencias significativas, mostrando en ambos casos una satisfacción subjetiva percibida alta. Conclusiones: Los cambios sociales, culturales, económicos e ideológicos ocurridos han favorecido el aumento de la edad materna y consigo el aumento de embarazos de riesgo, además de la disminución de la media del número de hijos. Se aprecia una necesidad en materia de apoyo e información a las mujeres en el periodo postparto debido al gran cambio personal, físico, social y psicológico que puede suponer.

Acidente vascular cerebral perinatal: 11 casos clínicos

Introdução: Os acidentes vasculares cerebrais (AVC) são causa de epilepsia e perturbações do neurodesenvolvimento. Têm tido uma incidencia crescente atribuível em parte à melhoria das tecnicas de imagens cerebrais. Alguns diagnósticos são efectuados retrospectivamente após o periodo neonatal. O objectivo da presente serie de casos clínicos foi identificar factores comuns que possam facilitar o diagnóstico no período neonatal. Material e métodos: Estudo retrospectivo efectuado com base na consulta dos processos clinicos dos recém-nascidos, com diagnóstico de AVC entre um de Janeiro de 2003 e 31 de Dezembro de 2013. Resultados: Foram identificados onze casos de AVC perinatal, num total 28382 nados-vivos. Dois casos foram diagnosticados no periodo fetal e nove no periodo neonatal. As convulsões foram a manifestação clinica mais frequente (8 em 11 casos). A mediana da idade de diagnóstico foi um dia e variou entre um e nove dias. A ecografia transfontanelar mostrou alterações em sete casos. A ressonancia magnetica nuclear cranio-encefalica mostrou alterações em todos os casos. Cinco AVC foram arteriais isquemicos, quatro hemorragicos e dois tromboses dos seios venosos. Em seis casos foram identificadas possiveis causas. Foram observadas complicações e sequelas em quatro dos casos. Discussão: As convulsões foram a manifestação clinica mais frequentemente encontrada.Em recém-nascidos de termo com convulsões sem historia de asfixia intraparto o AVC perinatal deverá ser diagnóstico de exclusão, mesmo na ausencia de alterações na ecografia transfontanelar.

Gestational Diabetes Mellitus in Far North Queensland, Australia, 2004 to 2010 : midwives’ perinatal data most accurate source

Objectives: This study examines the accuracy of Gestational Diabetes Mellitus (GDM) case-ascertainment in routinely collected data. Methods: Retrospective cohort study analysed routinely collected data from all births at Cairns Base Hospital, Australia, from 1 January 2004 to 31 December 2010 in the Cairns Base Hospital Clinical Coding system (CBHCC) and the Queensland Perinatal Data Collection (QPDC). GDM case ascertainment in the National Diabetes Services Scheme (NDSS) and Cairns Diabetes Centre (CDC) data were compared. Results: From 2004 to 2010, the specificity of GDM case-ascertainment in the QPDC was 99%. In 2010, only 2 of 225 additional cases were identified from the CDC and CBHCC, suggesting QPDC sensitivity is also over 99%. In comparison, the sensitivity of the CBHCC data was 80% during 2004–2010. The sensitivity of CDC data was 74% in 2010. During 2010, 223 births were coded as GDM in the QPDC, and the NDSS registered 247 women with GDM from the same postcodes, suggesting reasonable uptake on the NDSS register. However, the proportion of Aboriginal and Torres Strait Islander women was lower than expected. Conclusion: The accuracy of GDM case ascertainment in the QPDC appears high, with lower accuracy in routinely collected hospital and local health service data. This limits capacity of local data for planning and evaluation, and developing structured systems to improve post-pregnancy care, and may underestimate resources required. Implications: Data linkage should be considered to improve accuracy of routinely collected local health service data. The accuracy of the NDSS for Aboriginal and Torres Strait Islander women requires further evaluation.

Perinatal nutrition and gastrointestinal disorders : Working Group Report of the Second World Congress of Pediatric Gastroenterology, Hepatology, and Nutrition

Metabolic programming during the perinatal period as a consequence of early nutrition is an emerging area of great interest. This concept is known as the "fetal origins of adult disease" theory (1). Numerous epidemiological studies published over the past 20 years or so have suggested that small body size at birth and during infancy and, more specifically, intrauterine growth retardation are associated later in life with lowered cognitive performance and increased rates of coronary heart disease and its major biological risk factors, ie, raised blood pressure, insulin resistance, coronary artery disease, and abnormalities in lipid metabolism. The molecular mechanisms that govern this phenomenon in humans, however, are unknown and need to be elucidated.

Type 1 and type 2 diabetes among young adults in Finland : Incidence and perinatal exposures

This study aimed to examine the incidence of young adult-onset T1DM and T2DM among Finns, and to explore the possible risk factors for young adult-onset T1DM and T2DM that occur during the perinatal period and childhood. In the studies I-II, the incidence of diabetes was examined among 15-39-year-old Finns during the years 1992-2001. Information on the new diagnoses of diabetes was collected from four sources: standardized national reports filled in by diabetes nurses, the Hospital Discharge Register, the Drug Reimbursement Register, and the Drug Prescription Register. The type of diabetes was assigned using information obtained from these four data sources. The incidence of T1DM was 18 per 100,000/year, and there was a clear male predominance in the incidence of T1DM. The incidence of T1DM increased on average 3.9% per year during 1992-2001. The incidence of T2DM was 13 per 100,000/year, and it displayed an increase of 4.3% per year. In the studies III-V, the effects of perinatal exposures and childhood growth on the risk for young adult-onset T1DM and T2DM were explored in a case-control setting. Individuals diagnosed with T1DM (n=1,388) and T2DM (n=1,121) during the period 1992-1996 were chosen as the diabetes cases for the study, and two controls were chosen for each case from the National Population Register. Data on the study subjects parents and siblings was obtained from the National Population Register. The study subjects original birth records and child welfare clinic records were traced nationwide. The risk for young adult-onset T2DM was the lowest among the offspring of mothers aged about 30 years, whereas the risk for T2DM increased towards younger and older maternal ages. Birth orders second to fourth were found protective of T2DM. In addition, the risk for T2DM was observed to decrease with increasing birth weight until 4.2 kg, after which the risk began to increase. A high body mass index (BMI) at the BMI rebound between ages 3-11 years substantially increased the risk for T2DM, and the excess weight gain in individuals diagnosed with T2DM began in early childhood. Maternal age, birth order, or body size at birth had no effect on the risk for young adult-onset T1DM. Instead, individuals with T1DM were observed to have a higher maximum BMI before the age of 3 than their control subjects. In conclusion, the increasing trend in the development of both T1DM and T2DM among young Finnish adults is alarming. The high risk for T1DM among the Finnish population extends to at least 40 years of age, and at least 200-300 young Finnish adults are diagnosed with T2DM every year. Growth during the fetal period and childhood notably affects the risk for T2DM. T2DM prevention should also target childhood obesity. Rapid growth during the first years of life may be a risk factor for late-onset T1DM.

Balance of growth factors in the human perinatal lung : Implications for physiological lung development and link to bronchopulmonary dysplasia

The aims of this Thesis was to evaluate the role of proangiogenic placental growth factor (PlGF), antiangiogenic endostatin and lymphangiogenic vascular endothelial growth factor (VEGF) -C as well as the receptors vascular endothelial growth factor receptor (VEGFR) -2 and VEGFR-3 during lung development and in development of lung injury in preterm infants. The studied growth factors were selected due to a close relationship with VEGF-A; a proangiogenic growth factor important in normal lung angiogenesis and lung injury in preterm infants. The thesis study consists of three analyses. I: Lung samples from fetuses, preterm and term infants without lung injury, as well as preterm infants with acute and chronic lung injury were stained by immunohistochemistry for PlGF, endostatin, VEGF-C, VEGFR-2 and VEGFR-3. II: Tracheal aspirate fluid (TAF) was collected in the early postnatal period from a patient population consisting of 59 preterm infants, half developing bronchopulmonary dysplasia (BPD) and half without BPD. PlGF, endostatin and VEGF-C concentrations were measured by commercial enzyme-linked immunosorbent assay (ELISA). III: Cord plasma was collected from very low birth weight (VLBW) (n=92) and term (n=48) infants in conjuncture with birth and endostatin concentrations were measured by ELISA. I: All growth factors and receptors studied were consistently stained in immunohistochemistry throughout development. For endostatin in early respiratory distress syndrome (RDS), no alveolar epithelial or macrophage staining was seen, whereas in late RDS and BPD groups, both alveolar epithelium and macrophages stained positively in approximately half of the samples. VEGFR-2 staining was fairly consistent, except for the fact that capillary endothelial staining in the BPD group was significantly decreased. II: During the first postnatal week in TAF mean PlGF concentrations were stable whereas mean endostatin and VEGF-C concentrations decreased. Higher concentrations of endostatin and VEGF-C correlated with lower birth weight (BW) and associated with administration of antenatal betamethasone. Parameters reflecting prenatal lung inflammation associated with lower PlGF, endostatin and VEGF-C concentrations. A higher mean supplemental fraction of inspired oxygen during the first 2 postnatal weeks (FiO2) correlated with higher endostatin concentrations. III: Endostatin concentrations in term infants were significantly higher than in VLBW infants. In VLBW infants higher endostatin concentrations associated with the development of BPD, this association remained significant after logistic regression analysis. We conclude that PlGF, endostatin and VEGF-C all have a physiological role in the developing lung. Also, the VEGFR-2 expression profile seems to reflect the ongoing differentiation of endothelia during development. Both endostatin and VEGFR-2 seem to be important in the development of BPD. During the latter part of the first postnatal week, preterm infants developing BPD have lower concentrations of VEGF-A in TAF. Our findings of disrupted VEGFR-2 staining in capillary and septal endothelium seen in the BPD group, as well as the increase in endostatin concentrations both in TAF and cord plasma associated with BPD, seem to strengthen the notion that there is a shift in the angiogenic balance towards a more antiangiogenic environment in BPD. These findings support the vascular hypothesis of BPD.

Perinatal mortality and maternal health in rural China

Background and context Since the economic reforms of 1978, China has been acclaimed as a remarkable economy, achieving 9% annual growth per head for more than 25 years. However, China's health sector has not fared well. The population health gains slowed down and health disparities increased. In the field of health and health care, significant progress in maternal care has been achieved. However, there still remain important disparities between the urban and rural areas and among the rural areas in terms of economic development. The excess female infant deaths and the rapidly increasing sex ratio at birth in the last decade aroused serious concerns among policy makers and scholars. Decentralization of the government administration and health sector reform impacts maternal care. Many studies using census data have been conducted to explore the determinants of a high sex ratio at birth, but no agreement has been so far reached on the possible contributing factors. No study using family planning system data has been conducted to explore perinatal mortality and sex ratio at birth and only few studies have examined the impact of the decentralization of government and health sector reforms on the provision and organization of maternal care in rural China. Objectives The general objective of this study was to investigate the state of perinatal health and maternal care and their determinants in rural China under the historic context of major socioeconomic reforms and the one child family planning policy. The specific objectives of the study included: 1) to study pregnancy outcomes and perinatal health and their correlates in a rural Chinese county; 2) to examine the issue of sex ratio at birth and its determinants in a rural Chinese county; 3) to explore the patterns of provision, utilization, and content of maternal care in a rural Chinese county; 4) to investigate the changes in the use of maternal care in China from 1991 to 2003. Materials and Methods This study is based on a project for evaluating the prenatal care programme in Dingyuan county in 1999-2003, Anhui province, China and a nationwide household health survey to describe the changes in maternal care utilization. The approaches used included a retrospective cohort study, cross sectional interview surveys, informant interviews, observations and the use of statistical data. The data sources included the following: 1) A cohort of pregnant women followed from pregnancy up to 7 days after birth in 20 townships in the study county, collecting information on pregnancy outcomes using family planning records; 2) A questionnaire interview survey given to women who gave birth between 2001 and 2003; 3) Various statistical and informant surveys data collected from the study county; 4) Three national household health interview survey data sets (1993-2003) were utilized, and reanalyzed to described the changes in maternity care utilization. Relative risks (RR) and their confidence intervals (CI) were calculated for comparison between parity, approval status, infant sex and township groups. The chi-square test was used to analyse the disparity of use of maternal care between and within urban and rural areas and its trend across the years in China. Logistic regression was used to analyse the factors associated with hospital delivery in rural areas. Results There were 3697 pregnancies in the study cohort, resulting in 3092 live births in a total population of 299463 in the 20 study townships during 1999-2000. The average age at pregnancy in the cohort was 25.9 years. Of the women, 61% were childless, 38% already had one child and 0.3% had two children before the current pregnancy. About 90% of approved pregnancies ended in a live birth while 73% of the unapproved ones were aborted. The perinatal mortality rate was 69 per thousand births. If the 30 induced abortions in which the gestational age was more than 28 weeks had been counted as perinatal deaths, the perinatal mortality rate would have been as high as 78 per thousand. The perinatal mortality rate was negatively associated with the wealth of the township. Approximately two thirds of the perinatal deaths occurred in the early neonatal period. Both the still birth rate and the early neonatal death rate increased with parity. The risk of a stillbirth in a second pregnancy was almost four times that for a first pregnancy, while the risk of early neonatal deaths doubled. The early neonatal mortality rate was twice as high for female as for male infants. The sex difference in the early neonatal mortality rate was mainly attributable to mortality in second births. The male early neonatal mortality rate was not affected by parity, while the female early neonatal mortality rate increased dramatically with parity: it was about six times higher for second births than for first births. About 82% early neonatal deaths happened within 24 hours after birth, and during that time, girls were almost three times more likely to die than boys. The death rate of females on the day of birth increased much more sharply with parity than that of males. The total sex ratio at birth of 3697 registered pregnancies was 152 males to 100 females, with 118 and 287 in first and second pregnancies, respectively. Among unapproved pregnancies, there were almost 5 live-born boys for each girl. Most prenatal and delivery care was to be taken care of in township hospitals. At the village level, there were small private clinics. There was no limitation period for the provision of prenatal and postnatal care by private practitioners. They were not permitted to provide delivery care by the county health bureau, but as some 12% of all births occurred either at home or at private clinics; some village health workers might have been involved. The county level hospitals served as the referral centers for the township hospitals in the county. However, there was no formal regulation or guideline on how the referral system should work. Whether or not a woman was referred to a higher level hospital depended on the individual midwife's professional judgment and on the clients' compliance. The county health bureau had little power over township hospitals, because township hospitals had in the decentralization process become directly accountable to the township government. In the township and county hospitals only 10-20% of the recurrent costs were funded by local government (the township hospital was funded by the township government and the county hospital was funded by the county government) and the hospitals collected user fees to balance their budgets. Also the staff salaries depended on fee incomes by the hospital. The hospitals could define the user charges themselves. Prenatal care consultations were however free in most township hospitals. None of the midwives made postnatal home visits, because of low profit of these services. The three national household health survey data showed that the proportion of women receiving their first prenatal visit within 12 weeks increased greatly from the early to middle 1990s in all areas except for large cities. The increase was much larger in the rural areas, reducing the urban-rural difference from more than 4 times to about 1.4 times. The proportion of women that received antenatal care visits meeting the Ministry of Health s standard (at least 5 times) in the rural areas increased sharply from 12% in 1991-1993 to 36% in 2001-2003. In rural areas, the proportion increase was much faster in less developed areas than in developed areas. The hospital delivery rate increased slightly from 90% to 94% in urban areas while the proportion increased from 27% to 69% in rural areas. The fastest change was found to be in type 4 rural areas, where the utilization even quadrupled. The overall difference between rural and urban areas was substantially narrowed over the period. Multiple logistic regression analysis shows that time periods, residency in rural or urban areas, income levels, age group, education levels, delivery history, occupation, health insurance and distance from the nearest health care facilities were significantly associated with hospital delivery rates. Conclusions 1. Perinatal mortality in this study was much higher than that for urban areas as well as any reported rate from specific studies in rural areas of China. Previous studies in which calculations of infant mortality were not based on epidemiological surveys have been shown to underestimate the rates by more than 50%. 2. Routine statistics collected by the Chinese family planning system proved to be a reliable data source for studying perinatal health, including still births, neonatal deaths, sex ratio at birth and among newborns. National Household Health Survey data proved to be a useful and reliable data source for studying population health and health services. Prior to this research there were few studies in these areas available to international audiences. 3.Though perinatal mortality rate was negatively associated with the level of township economic development, the excess female early neonatal mortality rate contributed much more to high perinatal mortality rate than economic factors. This was likely a result of the role of the family planning policy and the traditional preferences for sons, which leads to lethal neglect of female newborns and high perinatal mortality. 4. The selective abortions of female foetuses were likely to contribute most to the high sex ratio at birth. The underreporting of female births seemed to have played a secondary role. The higher early neonatal mortality rate in second-born as compared to first-born children, particularly in females, may indicate that neglect or poorer care of female newborn infants also contributes to the high sex ratio at birth or among newborns. Existing family planning policy proved not to effectively control the steadily increased birth sex ratio. 5. The rural-urban gap in service utilization was on average significantly narrowed in terms of maternal healthcare in China from 1991 to 2003. This demonstrates that significant achievements in reducing inequities can be made through a combination of socio-economic development and targeted investments in improving health services, including infrastructure, staff capacities, and subsidies to reduce the costs of service utilization for the poorest. However, the huge gap which persisted among cities of different size and within different types of rural areas indicated the need for further efforts to support the poorest areas. 6. Hospital delivery care in the study county was better accepted by women because most of women think delivery care was very important while prenatal and postnatal care were not. Hospital delivery care was more systematically provided and promoted than prenatal and postnatal care by township hospital in the study area. The reliance of hospital staff income on user fees gave the hospitals an incentive to put more emphasis on revenue generating activities such as delivery care instead of prenatal and postnatal care, since delivery care generated much profits than prenatal and postnatal care . Recommendations 1. It is essential for the central government to re-assess and modify existing family planning policies. In order to keep national sex balance, the existing practice of one couple one child in urban areas and at-least-one-son a couple in rural areas should be gradually changed to a two-children-a-couple policy throughout the country. The government should establish a favourable social security policy for couples, especially for rural couples who have only daughters, with particular emphasis on their pension and medical care insurance, combined with an educational campaign for equal rights for boys and girls in society. 2. There is currently no routine vital-statistics registration system in rural China. Using the findings of this study, the central government could set up a routine vital-statistics registration system using family planning routine work records, which could be used by policy makers and researchers. 3. It is possible for the central and provincial government to invest more in the less developed and poor rural areas to increase the access of pregnant women in these areas to maternal care services. Central government together with local government should gradually provide free maternal care including prenatal and postnatal as well as delivery care to the women in poor and less developed rural areas. 4. Future research could be done to explore if county and the township level health care sector and the family planning system could be merged to increase the effectiveness and efficiency of maternal and child care. 5. Future research could be done to explore the relative contribution of maternal care, economic development and family planning policy on perinatal and child health using prospective cohort studies and community based randomized trials.

Con el objeto de conocer la prevalencia de Cisticercosis bovina, así como las regiones de mayor afectación y las implicaciones económicas que ello ocasiona en animales faenados en el matadero NUEVO CARNIC, ubicado en el km 10 carretera norte, un km. al norte para el periodo de enero a junio de l 2008, se llevó a cabo el presente estudio, l os datos recopilados se obtuvieron de los registros de matanza del primer semestre del año 2008 (enero a junio), los cuales provenían de los registros de inspección postmorten realizados por los inspectores veterinarios, quienes utilizan el método del reglamento de inspección veterinaria de la carne para la republica de Nicaragua. El presente estudio fue observacional de tipo transversal, por estar determinado en un momento de la actividad del matadero. La determinación de la prevalencia consistió en determinar el número de animales afectados, los cuales se relacionaron con el número de animales faenados por lotes y total. Al iniciarse el estudio, sólo se conocía el número total de individuos que se incluyeron. La medición de la cantidad de enfermedad y de los factores de exposición se realizó simultáneamente una vez seleccionada la muestra. Las variables evaluadas fueron, prevalencia por tamaño del lote y total de animales faenados, regiones anatómicas de mayor afectación y pérdidas económicas para los ganaderos por sanitización y condena. Se encontró una prevalencia de 0.85% con respecto al total de animales faenados, y un 0.04% para animales condenados. La categoría que presentó mayor prevalencia y pérdidas económicas por C. bovis fue toro, seguida de la categoría vacas. El municipio de mayor frecuencia de afectación fue Managua. Las procedencias de San Lorenzo, el Tuma, Ayapal, Paiwas, Muy Muy, Boaco, Nagarote, Estelí, y la Paz Centro fueron los municipios con mayor prevalencia con respecto al total de animales faenados. Cuando el tamaño del lote es mayor de 50 animales la probabilidad de ocurrencia de prevalencia por lote y total son mayores. La región anatómica con mayor prevalencia fueron los músculos maseteros, seguido de la lengua. Las pérdidas económicas para los productores ascendieron a más de 2,000 dólares por mes. Los meses de mayores pérdidas fueron Junio y Marzo. Las procedencias y los pesos no son factores a considerar en los porcentajes de afectación y prevalencia de la enfermedad.

De los 59 bovinos afectados por Afecciones hepáticas, el 51% presentaron hepatitis, el 12% se refiere peri hepatitis, 10% a hepatitis telangiectasia, 5% a hepatitis pigmentación 3.4% hepatitis crónica, hepatitis absceso, peri hepatitis fibrinosa y absceso, y los rangos de 1.7% corresponden a hemorragia, adherencia, telangiectasia absceso, combina 1 y 9, (hepatitis focal crónica, degeneración, hiperplasia de canalículos biliares) 7 y 9 (degeneración, hemorragia, hiperplasia de canalículos biliares). Las pérdidas económicas por la cantidad hígados condenados fue de C$ 14, 160.00 córdobas que en dólares equivale a US$ 734.013.00 de acuerdo a la tasa de cambio del período estudiado.

Caracterizacion del comportamiento de la estomatitis vesicular en animales domesticos de pezuña hendida en la sexta region (Jinotega y Matagalpa) en el periodo 2008

El presente trabajo se realizó con el fin de contribuir al conocimiento dando a conocer la Caracterización del comportamiento de la estomatitis Vesicular en animales domésticos de pezuña hendida en la región VI (Jinotega y Matagalpa) en el periodo 2008, debido a su gran poder de difusión considerando que en Nicaragua no existe un programa de erradicación o control de la estomatitis vesicular, aunque los humanos también pueden contraer estomatitis vesicular. Se hizo necesario realizar un monitoreo de la enfermedad en esta región, determinar el tipo de cepa que es mas prevalente en la especie de pezuña hendida y el lugar anatómico que más afecta , se tomaron muestras en conjunto con técnicos del MAGFOR y fueron enviadas al Laboratorio de Diagnóstico de Enfermedades Vesiculares (LADIVES) ,localizado en Panamá, se llevó a cabo un análisis estadístico descriptivo, para este análisis se utilizó la información que se colectó en los casos atendidos entre el mes de Julio a Diciembre 2008 y la información retrospectiva de Enero a Junio, con apoyo de la base de datos de Enfermedades Vesiculares que lleva la oficina del Convenio Bilateral Antiaftosa (CAB) del MAGFOR Se elaboraron distribuciones de frecuencia, para las variables; diagnóstico, prevalencia, especie animal y región anatómica, lo que nos accedió informarnos sobre los valores concretos que adoptaron las variables a analizar y sobre el número(o porcentaje) de veces que se repite cada uno de esos valores y nos permitió construir los diagramas con los resultados, concluyendo que de un total de 132 muestras enviadas al laboratorio 82 resultaron positivas a Estomatitis Vesicular, 44 de ellas resultaron al serotipo New Jersey en la zona de Matagalpa y 33 en Jinotega, 5 resultaron positivas al serotipo Indian a en Matagalpa y en la región de Jinotega no se presentó ninguna positiva a este serotipo, la especie más afectada fue el bovino, de las 132 muestras enviadas 129 fueron tomadas en esta especie, siendo las pezuñas el lugar anatómico de mayor predilección para el virus, del total de muestras 91 se tomaran esta región, manifestándose con mayor frecuencia en épocas de lluvia sobre todo en los meses de mayo a octubre.
