Sensibilización al gato en pacientes con alergia respiratoria, experiencia de una institución universitaria

Antecedentes: La frecuencia de sensibilización al gato en sujetos con alergia respiratoria puede ser hasta de 60% y es un factor de riesgo para desarrollar alergia al gato. Objetivo: Establecer la frecuencia de sensibilización al gato por exposición ambiental y por prueba cutánea al alérgeno de gato Fel d1 en pacientes con alergia respiratoria. Métodos: Estudio transversal prospectivo comparativo realizado de agosto a noviembre del 2009. Se Incluyeron 198 sujetos divididos en dos grupos (un grupo de 98 pacientes con alergia respiratoria y otro con 100 controles sanos). Se les aplicó un cuestionario clínico epidemiológico y prueba cutánea con alérgeno de gato Fel d1 (1:20 p/v) mediante el método de punción epicutánea (Prick-test). Resultados: La frecuencia de sensibilización al gato medida por prueba cutánea en pacientes con alergia respiratoria fue de 25% comparado con 10% en sanos (p = 0.004). En los sujetos con rinitis alérgica y asma la frecuencia de sensibilización al gato fue de 31% y en los sujetos que tenían exclusivamente rinitis alérgica fue de 22% (p = 0.416). La presencia de síntomas a la exposición ambiental con gato en el grupo de pacientes con alergia respiratoria fue de 19%, en los sujetos sanos fue de 2% (p < 0.001). La presencia de gato en casa en pacientes con alergia respiratoria que fueron sensibles a la prueba cutánea de alérgeno de gato fue de 1%. Los pacientes tuvieron una frecuencia de sensibilidad a otros alérgenos como D. pteronyssinus (80%), D. farinae (72%), Cynodon (52%), Amaranthus, Salsola y Fraxinus (40% cada uno). Conclusión: La frecuencia de sensibilización al gato en sujetos con alergia respiratoria fue de 25%, similar a lo informado por otras series

Prevalence of allergy to hymenoptera sting among schoolchildren in Monterrey, México

Las picaduras de himenópteros pueden causar reacciones alergicas en individuos sensbilizados a su veneno. Hay pocos datos epidemiologicos sobre la prevalencia de este tipo de alergia en niños en México. El principal estudio de este año es conocer la prevalencia de la alergia al veneno de himenópteros en escolares de Monterrey, México

Evaluación de la función olfatoria en pacientes con rinopatía crónica.

Las enfermedades inflamatorias crónicas de la nariz se asocian con un defecít del flujo de aire y de la conducción en la mucosa olfatoria, por lo que estos procesos patológicos comúnmente se acompañan de disminución de la olfación

Prevalencia de trastornos dentomaxilofaciales en niños con rinitis alérgica que acuden a la consulta del Centro Regional de Alergia e Inmunología Clínica del Hospital Universitario "Dr. José E. González (abs)

La rinitis alérgica es el tipo mas común de rinitis crónica y una de las principales causas de respiración oral en niños. Existen pocos estudios que determinen las alteraciones dentomaxilofaciales en niños con rinitis alérgica y respiración oral

Annual Sexual Behavior in Boer Bucks Located in the Guerrero Tropics in Mexico

The aim of this study was to evaluate the intensity of the annual sexual behavior (SB) of Boer bucks under tropical conditions in southern Mexico. For one year, 16 extensively grazing males were evaluated for SB individually with estrogenized goats. From the beginning of the experiment and every 30 days, body weight (BW), body condition (BC), testicular circumference (TC), odor intensity (OI), and SB (nudging, ano-genital sniffing, flehmen, mounting attempts, mounts with intromission, and self-urination) were recorded. The bucks showed more intense SB during the months of November to May than during the months of June to October (p p p p p < 0.001). In fact, an increased odor was found from October to December. The conclusions are that breed male goats from the tropics of Guerrero have a more intense SB during the months of November to May, but TC, OI, BW, and BC correspond to the time of the year when forage availability is the greatest

Evaluation of functional capacity by 6-minute walk test in children with asthma

Background: Asthma patients show lower exercise tolerance. Objective: Assessment of functional capacity in children with asthma. Methods: Girls and boys from 6 to 17 years old were included in two groups: asthmatic patients and healthy subjects. PSPQ was applied and vital signs, peak expiratory flow and Modified Borg Dyspnea Scale were measured at the beginning and the end of 6MWD. Results: Participants included 58 subjects, including 32 asthmatic patients, and 55.2 % male subjects. Mean age: 10.6 years ± 3.1. Asthmatic group: mean distance covered in meters 456.04 ± 54.05, meters covered by gender 456.31 ± 48.73 male and 455.74 ± 61.29 female (p = 0.28). Control group: the mean was 468.28 ± 54.52 meters, meters covered by gender 465.98 ± 58.04 male, 471.44 ± 51.95 female (p = 0.35). The difference between asthmatic group and control group was 12.24 meters in favor of control group (p = 0.378). There was no association between body mass index (BMI) and distance covered (p = 0.53), but a Pearson correlation p = -0.445. In the male gender, CF was positively associated with self-perception in CAF variables: physical condition, physical attractiveness, strength (p = 0.04) and physical self-concept in general (p = 0.02). Conclusions: There was no significant difference in the distance covered between the two groups. The main impact factor was the body mass index with an inverse relation to the distance. Males had better physical self-perception, which is positively associated with CF

Contemporary use of cefazolin for MSSA infective endocarditis: analysis of a national prospective cohort

Objectives: This study aimed to assess the real use of cefazolin for methicillin-susceptible Staphylococcus aureus (MSSA) infective endocarditis (IE) in the Spanish National Endocarditis Database (GAMES) and to compare it with antistaphylococcal penicillin (ASP). Methods: Prospective cohort study with retrospective analysis of a cohort of MSSA IE treated with cloxacillin and/or cefazolin. Outcomes assessed were relapse; intra-hospital, overall, and endocarditis-related mortality; and adverse events. Risk of renal toxicity with each treatment was evaluated separately. Results: We included 631 IE episodes caused by MSSA treated with cloxacillin and/or cefazolin. Antibiotic treatment was cloxacillin, cefazolin, or both in 537 (85%), 57 (9%), and 37 (6%) episodes, respectively. Patients treated with cefazolin had significantly higher rates of comorbidities (median Charlson Index 7, P <0.01) and previous renal failure (57.9%, P <0.01). Patients treated with cloxacillin presented higher rates of septic shock (25%, P = 0.033) and new-onset or worsening renal failure (47.3%, P = 0.024) with significantly higher rates of in-hospital mortality (38.5%, P = 0.017). One-year IE-related mortality and rate of relapses were similar between treatment groups. None of the treatments were identified as risk or protective factors. Conclusion: Our results suggest that cefazolin is a valuable option for the treatment of MSSA IE, without differences in 1-year mortality or relapses compared with cloxacillin, and might be considered equally effective
