Objetivo: comprobar la relación entre el flujo y la capacidad amortiguadora salival con la experiencia de caries, en niños con bajo y alto índice de dientes cariados, perdidos y obturados (CPOD). Método: Se realizó un estudio descriptivo transversal a un grupo de 60 niños de 6 a 11 años de edad, de ambos sexos, admitidos para consulta en la Clínica de Admisión de la Facultad de Odontología de la Universidad Autónoma de Baja California, sede Mexicali. Se establecieron dos grupos en función del CPOD: grupo 1 (puntuación 0-3) y grupo 2 (4 o más). Se elaboró una historia clínica que incluyó tanto los datos generales del niño como el registro de la experiencia de caries bajo los criterios de la Organización Mundial de la Salud. Asimismo, se midieron y registraron el volumen de saliva estimulada y la capacidad amortiguadora para cada sujeto. Resultados: se observó una correlación negativa (r=¿0,221) entre el flujo salival y el CPOD; sin embargo, esta tendencia no fue estadísticamente significativa (p0,05). En cuanto a la capacidad amortiguadora, se hallaron diferencias estadísticamente significativas al relacionar una mayor capacidad amortiguadora y un CPOD bajo (p0,05). Conclusión: la mayor capacidad amortiguadora de la saliva se relacionó con la menor experiencia de caries. Por su parte, el flujo salival estimulado mostró alguna asociación descriptivamente con el CPOD, pero dicha asociación no fue estadísticamente significativa.

To determine risk factors associated to Burnout Syndrome in medical gynecologist staff who works at the Gynecology-pediatrics with Family Medicine Hospital number 31 of the IMSS at Mexicali city, Baja California.A cross sectional study was performed in 27 gynecologists (100% of the total gynecologist that works at that particular hospital). A validated survey instrument developed by Maslach was applied to them in order to identify the presence of the syndrome and a general questionnaire including sociodemographic information was also applied to the doctors. The statistical analysis was both descriptive and inferential including chi square, Student t and logistic regression.74.1% of the doctors who showed signs of Burnout Syndrome were males and 25.9% were females. The average doctors age of the group who developed Burnout was 44.81 +/- 6.11 years. The mean time in years of work for the doctors with the syndrome was 15.56 +/- 7.11 years. Only one doctor was divorced and she presented Burnout Syndrome, on the other hand, 62.5% of the married doctors showed evidence of Burnout Syndrome (p0.05). The general prevalence was 59.2%. Of those who showed signs of burnout, 87.5% presented it in low degree, 6.2% presented moderate degree, 6.2% presented high burnout degree. Out of all the organizational factors type, none resulted significative.The prevalence of the reported syndrome is apparently high when compared to the medical anesthesiology staff of the same hospital; however this difference is not statistically significative. In the unvaried and multivariate analyses, no organizational factor shows significance as a potential risk. It is necessary to consider psychological support to the affected doctors and to value the organization of the service, looking for an administrative reengineering.

To determine the prevalence of burnout syndrome in nursing staff in 2 different second level hospitals in the city of Mexicali, Baja California, Mexico.A cross-sectional study was conducted in all nursing staff (n = 698) in 2 second level hospitals (the Gynecology, Pediatrics and Family Medicine Hospital No. 31 and the General Specialist Hospital No. 30 in Mexicali). A stratified random sample was obtained from the 698 nurses, with a sample size of 184 nurses from each hospital. The Maslach Burn-out Inventory and a general questionnaire on demographic factors were used. Statistical analysis consisted of descriptive statistics and analysis of proportions using the chi-squared test.A total of 368 nurses were studied, of whom 345 (93.75%) were women. The mean age was 41.21 SD (standard deviation) = 6.59 years. The mean length of service was 15.87 (SD = 6.12) years. In both hospitals, the prevalence of burnout syndrome was 6.79% (25).Previous publications on burn-out have included studies performed in Mexico and in nurses in the emergency department of a tertiary hospital in Barcelona, as well as in other health care professionals. In comparison with these studies, the prevalence of burn-out observed in the present study was significantly lower.

To determine the prevalence of Burnout syndrome among anesthesiologists in Mexicali, Mexico.We carried out a descriptive, cross-sectional study. Burnout syndrome was measured using the Maslach Burnout Inventory-Human Services Survey (MBI-HSS). We administered the inventory to 92 anesthesiologists between October 2001 and February 2002. Statistical analysis included Chi square tests for categorical variables.89 questionnaires were returned, 22 females and 67 males. Burnout prevalence was 44% divided as follows: 17% reported high emotional exhaustion, 12.3% reported symptoms compatible with depersonalization, and 10% experienced a sense of low personal accomplishment.Our study differs slightly from the literature, although this may be attributed to the medical specialty we chose to survey. We suggest similar studies be carried out in other cities in Mexico to be able to have comparison groups.

El objetivo fue determinar la seroprevalencia e identificar los factores de riesgo asociados a la brucelosis bovina en hatos lecheros ubicados en el municipio de Tijuana, Baja California. Se realizó de septiembre de 1999 a septiembre del 2000, con una población en estudio de 19,000 bovinos lecheros mayores de seis meses de edad. Para determinar la seroprevalencia se utilizaron las pruebas de tarjeta y fluorescencia polarizada. Se dise #324;ó un cuestionario epidemiológico con el propósito de identificar los factores de riesgo asociados con la enfermedad. La seroprevalencia determinada por fluorescencia polarizada fue del 6.4 %. Las variables que presentaron asociación en el análisis univariable con la seropositividad a la brucelosis fueron: no remoción de desechos de abortos y partos, 2.40 razones de momios (RM), presencia de perros (RM = 2.65), orde #324;a de reactores antes o junto con animales sanos (RM= 6.74), no eliminación de reactores (RM= 6.19). En el análisis multivariado por regresión logística se observó que la variable orde #324;a fue significativa (RM ajustado = 4.65) y la edad, tomando como punto de corte dos a #324;os, fungió como variable de confusión (RM ajustado = 4.94). La prevalencia global de la brucelosis encontrada se puede considerar como moderada. La zonas productoras con la más alta prevalencia fueron la Gloria y el Murua. El estudio deja en claro cuales fueron los factores de riesgo que se asociaron con la enfermedad, lo cual posibilita un éxito mayor en la aplicación de un programa de control y erradicación.

In a blind, placebo-controlled trial, a homoeopathic dynamized dilution of Sulphur 201c was given orally to pregnant sows every 10 days. No significant difference was detected between the birth weight of litters (39 piglets) of treated sows and control litters (40 piglets). On day 30 statistically significant differences were observed both in the final weight of litters, mean total and daily weight gain.
