Objetivo: Determinar la existencia de un patrón familiar de agregación del síndrome de intestino irritable (SII). Diseño: Es un estudio de casos y controles con proporción 1:2, llevado a cabo en una consulta externa de medicina general-familiar. Participantes: Hombres y mujeres de 18 a 60 años. Participaron 40 casos con SII de acuerdo con criterios de Roma IV, y 80 controles integrados por familiares sin alguna enfermedad gastrointestinal. Las mediciones principales fueron variables sociodemográficas, algún evento estresante relacionado, patrón evacuatorio predominante y patrón de repetición familiar para SII. Se analizaron los datos con estadísticas descriptivas e inferenciales. X2 para datos categóricos, estimación de odds ratio (OR) con intervalo de confianza (IC) 95%. Fue aprobado por el comité de ética institucional. Resultados: Hubo repetición del patrón de presentación del SII en familiares principalmente de primer grado. Fue mayor el riesgo de padecer este síndrome cuando el padre lo reportó (OR de 11,2; IC 95% 2-100,1), que cuando la madre lo presentó (OR 3,7; IC 95% 1,4-9,9), o hermano(a) (OR 2,8; IC 95% 1,1-6,6). En ambos grupos, el familiar que más frecuentemente presentaba SII fue en la línea colateral (hermano/a) (37,5% en los casos vs. 17,5% en los controles [p=0,023]). En ambos grupos el género predominante fue el femenino con 80,0% en los casos y 57,5% en los controles. Conclusión: Existe en la población mexicana un patrón de agregación familiar. La enfermedad es más frecuente en familiares en primer grado. Es importante dilucidar si quien desempeña el rol más importante en SII es el trasfondo genético o el entorno familiar.(AU)


Objective: To determine a family aggregation pattern of Irritable Bowel Syndrome (IBS). Design: it is a case-control study with a 1.2 ratio. Setting. External consultation of a general family medicine practice. Participants: men and women from 18 to 60 years old. Cases (40): people with IBS according to the Rome IV criteria, and Controls (80): relatives without gastrointestinal disease. Main measurements. Sociodemographic variables, related stressful events, predominant evacuation patterns, and family repetition patterns for IBS. Data were analyzed with descriptive and inferential statistics. Chi-square for categorical data (< p.05 as significant) estimate of ORs with 95% confidence interval. The institutional ethics committee approved it. Results: The IBS presentation pattern was repeated in relatives, mainly first-degree. The risk of suffering from IBS was higher when the father reported it (OR 11.2 (95% CI; 1.2 -100.1), than the mother OR 3,7 (95% CI; 1.4 – 9.9), sibling OR 2.8 (95% CI; 1.1 – 6.6. In both groups, the relative who most frequently presented IBS was in the collateral line (sibling) (37.5% in cases vs. 17.5% in controls (p=0.023). In both groups, the predominant gender was female, with 80. 0% in cases and 57.5% in controls. Conclusion: SII has a familial recurrence pattern in the Mexican population. The disease is more frequent in first-degree relatives. It is important to elucidate the importance of the role that plays genetic background vs. the influence of the family environment in SII.(AU)

INTRODUCTION: In the care of patients with medically unexplained physical symptoms (MUPS) it is important what they think about their symptoms. OBJECTIVE: To validate the psychometric properties of a symptom attribution scale in patients with MUPS and to verify its reliability. METHODS: A non-probabilistic sample of 400 male and female adult patients were interviewed in the outpatient services of a family medicine hospital, 200 with MUPS and 200 with a defined organic pathology. Each group was diagnosed with defined criteria, and a scale with content and construct validity was applied by means of principal component analysis with varimax rotation. RESULTS: The scale was made up of 12 items with two factors, one of symptom psychosocial attribution and other with organic attribution. The psychosocial-origin factor showed a variance of 49.7%. The goodness-of-fit test demonstrated that the correlation matrix was adequate, and Bartlett's sphericity test indicated statistical significance (p < 0.0001); Cronbach's alpha was 0.841. CONCLUSION: The scale showed acceptable construct validity and good reliability and stability. The implications of these results for future measurement research are discussed.


INTRODUCCIÓN: En la atención de pacientes con síntomas físicos médicamente no explicables (SFMNE) es importante lo que el paciente piensa de sus síntomas. OBJETIVO: Validar propiedades psicométricas de una escala de atribución del síntoma en pacientes con SFMNE y verificar su confiabilidad. MÉTODOS: Se entrevistó a una muestra no probabilística de 400 pacientes adultos, hombres y mujeres, en la consulta de un hospital con medicina familiar, 200 con SFMNE y 200 con patología orgánica concreta. Se diagnosticó a cada grupo con criterios definidos y se aplicó una escala con validez de contenido y de constructo por medio de análisis de componentes principales con rotación varimax. RESULTADOS: La escala quedó integrada por 12 reactivos con dos factores, uno de atribución psicosocial y otro de atribución orgánica del síntoma. El factor de origen psicosocial tuvo una varianza de 49.7 %. La prueba de bondad de ajuste mostró que la matriz de correlaciones fue adecuada y la prueba de esfericidad de Bartlett indicó significación estadística (p < 0.0001); el alfa de Cronbach fue de 0.841. CONCLUSIÓN: La escala mostró una validez de constructo aceptable y buena confiabilidad y estabilidad. Se discuten las implicaciones de estos resultados para la investigación de mediciones futuras.

THERE ARE ANALYZED SOME OF THE MAIN ASPECTS RELATED TO THE CAUSALITY OF PREECLAMPSIA, PRIVILEGING TWO TYPES OF MODELS: the clinic model and the epidemiologic model, first one represented by the hypothesis of the reduced placental perfusion and the second one considering the epidemiologic findings related to the high levels of psychosocial stress and its association with preeclampsia. It is reasoned out the relevance of raising the causality of the disease from an interdisciplinary perspective, integrating the valuable information generated from both types, clinical and epidemiologic, and finally a tentative explanatory model of preeclampsia is proposed, the subclinical and sociocultural aspects that predispose and trigger the disease are emphasized making aspects to stand out: the importance of reduced placental perfusion as an indicator of individual risk, and the high levels of physiological stress, as a result of the unfavorable conditions of the psychosocial surroundings (indicator of population risk) of the pregnant women.
