To determine the association between family typology and dysfunction in families with adolescents in a Mexican population. Cross-sectional observational study. A total of 437 families in a Mexican population with adolescents attending a public high school. Determination of family typology (Mexican Family Medicine Council and Consensus) and family function (family APGAR) in adolescents and their parents/guardians. Identification of families with concordant perceptions among members (Cohen kappa), in which the association between typology and perception of family dysfunction was determined (odds ratio [OR]). The types of families are associated with family function by kinship, physical presence in the home and the level of family poverty. From the perception of the adolescent, the types are associated with: simple nuclear (OR 0.5, 95% CI 0.3-0.8), extended single parent (OR 1.9, 95% CI 1.03-3.5), integrated nucleus (OR 0.6, 95% CI 0.4-0.9), low family poverty (OR 0.5, 95% CI 0.3-0.8), and high family poverty (OR 5.3, 95% CI 1.5-18.6). From the perception of the tutor: the single parent (OR 1.9, 95% CI 1.09-3.4), and high family poverty (OR 2.9, 95% CI 1.1-7.7). There were 259 families with concordant perception of family function/dysfunction with a κ=0.189, determining that the types associated are: simple nuclear (OR 0.4, 95% CI 0.2-0.7), single-parent (OR 1.7, 95% CI 0.80-3.8), integrated nucleus (OR 0.5, 95% CI 0.3-0.8), non-integrated nucleus (OR 1.9, 95% CI 1.09-3.5), and high family poverty (OR 13.8, 95% CI 1.7-108.5). The family types with adolescents associated with family dysfunction are single-parent families with a non-integrated nucleus and high family poverty, and as protective factors, the simple nuclear and integrated nucleus.

Introducción. El trauma cervical penetrante es una entidad poco frecuente, con tendencia al alza, de considerable morbimortalidad. Es fundamental conocer su manejo por cirujanos en entrenamiento, quienes en su mayoría son comúnmente los proveedores del tratamiento en las áreas de urgencias. El objetivo de este estudio fue demostrar la experiencia de un centro de trauma en México en el tratamiento de trauma cervical penetrante administrado por cirujanos en entrenamiento. Métodos. Estudio retrospectivo de pacientes con diagnóstico de trauma cervical penetrante sometidos a exploración cervical entre los años 2014 y 2019. Se identificaron 110 expedientes, se excluyeron 26 por falta de datos indispensables para la investigación y se analizaron los datos de 84 pacientes. Resultados. El 96,4 % de los pacientes fueron hombres, la mayoría entre 16 y 50 años (83,3 %) y la zona anatómica II fue la más comúnmente lesionada (65,4 %). Las etiologías más frecuentes fueron heridas por arma cortopunzante (67,9 %) y heridas por proyectil de arma de fuego (25 %). El 95 % de los procedimientos fueron realizados por residentes de cuarto y quinto año. La mediana de días de estancia hospitalaria fue de 2 días. La incidencia de complicaciones fue de 9,5 % y la mortalidad de 1,2 %. Conclusiones. Los cirujanos generales en etapa de formación entrenados en centros de trauma tienen la capacidad de tratar de forma óptima el trauma cervical penetrante sin modificación de las tasas de morbimortalidad descritas en la literatura internacional.

Background: Specific IgE against Staphylococcus can be found in approximately 40% of patients with allergies, also in patients without allergies because they may be sensitized. These antibodies are functional, and they can induce histamine release contributing to chronic pruritus which can worsen disease severity. The objective of this study was to compare levels of specific IgE against S. aureus toxins in those populations. Methods: A cross-sectional, comparative non-blinded survey was made at the Regional Center for Allergy and Clinical Immunology. Ninety-nine adults between 18 and 70 years of age with allergic rhinitis (AR) and without allergic rhinitis (wAR) were recruited. A clinical history and demographic data, and allergic sensitization patterns to 35 aeroallergens were obtained, and participants were classified according to their severity using the Allergic Rhinitis and Its Impact on Asthma (ARIA) classification. Specific IgE levels were determined using ImmunoCAP™ 100 platform. Results: The median age (IQR) of the participants was 23 (20– 33.7); 56.2% were women. The most frequent comorbidities were asthma and obesity. Of the patients with AR, 46.7% were classified as mild intermittent and 25% as moderate persistent. IgE levels against staph toxins A, B, and TSST were significantly higher in the AR group vs the wAR group [median IQR 0.01 (0.01– 0.03) vs. 0.01 (0– 0.02), p = 0.01; 0.02 (0.01– 0.03) vs. 0.01 (0– 0.02), p= 0.02; 0.04 (0.02– 0.09) vs. 0.01 (0– 0.04), p=0.002, respectably]. A significant difference was found in serum IgE levels against Staph B toxin between severity subgroups. Conclusion: People with AR have higher IgE levels against staph toxins A, B and TSST than wAR subjects. However, it is not possible declare that the IgE titers were related to disease severity.
