ABSTRACT

Desde las observaciones de Quincke y Osler, que refirieron pacientes con una "tumefacción" diferente de las que provocaban habitualmente los mecanismos alérgicos hasta el descubrimiento de un nuevo mediador responsable de esos edemas dolorosos y deformantes, se han sucedido los aportes de los investigadores en el esclarecimiento de la patogenia y el tratamiento del AEH hasta la actualidad, en que el arsenal terapéutico se ve notablemente enriquecido por medicamentos altamente eficaces y específicos. Intentaremos describirlos. (AU)


From the observations of Quincke and Osler, who referred patients with a "swelling" different from those that usually provoked the allergic mechanisms until the discovery of a new mediator responsible for these painful and deforming edemas, have been the contributions of researchers in the Clarification of the pathogenesis and treatment of HAE to date, where the therapeutic arsenal is remarkably enriched by highly effective and specific drugs. We will try to describe them.(AU)

ABSTRACT

A pesar de que el angioedema hereditario es un padecimiento raro, tiene una amplia bibliografía que ratifica que la fisiopatología de esta enfermedad es compleja. La constante investigación de la industria farmacéutica no solo ha aportado nuevos recursos terapéuticos sino que ha logrado despertar un inusitado interés en la comunidad médica, permitiendo que tengamos una mayor comprensión sobre los mecanismos que presiden la aparición de las crisis. El Comité de Angioedema Hereditario de la AAAeIC ha desarrollado una puesta al día sobre esta entidad, que, por las características de sus síntomas, es abordada principalmente por los especialistas en alergia e inmunología clínica(AU)


Although hereditary angioedema is a rare condition, it has a large number of references that confirm that the pathophysiology of this disease is complex. The constant research of the pharmaceutical industry has not only brought new therapeutic resources, but also aroused an unusual interest in the medical community, allowing us to have a better understanding of the mechanisms that perform the onset of crises. The AAA e IC Hereditary Angioedema Committee has developed an update on this entity, which, due to the characteristics of its symptoms, is mainly addressed by specialists in allergy and clinical immunology.(AU)

ABSTRACT

Objetivo: Nuestro país, por su riqueza cultural, presenta diversas concepciones en torno al embarazo, parto y puerperio. Las costumbres y los procesos de embarazo, parto y puerperio, de la mujer Awajun (Aguaruna) o Wampis (Huambisa), en el contexto cultural de las comunidades indígenas, son revisadas en el presente estudio. Materiales y métodos: Estudio etnográfico descriptivo, cualitativo, realizado durante octubre de 2002 a abril de 2003, aplicándose 24 entrevistas a profundidad (a parteras, promotores de salud y usuarias), en las comunidades de Puerto Galilea y Chapiza, además de tres grupos focales. Dichas entrevistas se analizaron en función de cinco aspectos, relacionados con señales, peligros, dietas y cuidados durante el embarazo, parto y puerperio. Resultados: Los pobladores reconocen algunas señales depeligro en el embarazo, como el sangrado vaginal y pérdida de líquido amniótico. Los cuidados durante el embarazo se relacionan con las actividades diarias y la ingesta de alimentos (dietas). Existen algunos elementos que dificultan el parto y nacimiento, como el sentimiento de vergüenza para llamar al promotor. Logrado el parto, debe mantenerse los cuidados para la recuperación de la madre, y un decuado desarrollo del recién nacido. Conclusiones: Las concepcionesy percepciones del embarazo, parto y puerperio en comunidades nativas, norman el comportamiento de suspobladores, repercutiendo esto en la salud materna e infantil. Es necesario comprender esta cultura y capacitar agentes de medicina tradicional, implementando estrategias en promoción de la salud y atención de la gestante, fortaleciendo las capacidades institucionales e incrementando la cobertura.


Objective: Our country, due to its cultural richness, has many different conceptions with respect to pregnancy, delivery, and puerperium. Customs and occurrences during pregnancy, delivery and puerperium in Awajun (aguaruna) or Wampis (Huambisa) native women are reviewed in this study. Materials and methods: Ethnographic, descriptive, and qualitative study performed from October 2002 to April 2003. 24 in-depth interviews were carried out in midwives, healthcare promoters, and clients in Puerto Galilea and Chapiza communities, three focal groups were also assessed. The aforementioned interviews were analyzed taking into account five aspects related with signals, dangers, diet, and care to be taken during pregnancy, delivery, and puerperium. Results: People recognize some danger signals during pregnancy, such as vaginal bleeding and amniotic fluid loss. Care to be taken during pregnancy is related to daily activities and diets to be followed. There are some elements that pose difficulties for pregnancy and delivery, such as being ashamed to call a healthcare promoter. Once delivery occurs, care must be taken so that the mother recovers and the newborn has adequate development. Conclusions: Conceptions and perceptions with respect to pregnancy, delivery, and puerperium in native communities regulate people’s behavior, and this influences both mother and child health. It is necessary to understand this culture and to train health promoters with appropriate knowledge of traditional medicine, implementing health promotion and pregnant women health care strategies, strengthening institutional capacities and increasing health care coverage.

ABSTRACT

El estímulo eléctrico plantar (EEP) aplicado a ratas conscientes, incrementa la presión arterial media (PAM) y la frecuencia cardíaca (FC). En el presente trabajo evaluamos la hipótesis que la angiotensina II (ANG II) endógena media la respuesta simpática frente al EEP. Nuestros resultados muestran que el bloqueo del receptor AT1 con losartan, valsartan o eprosartan previene la respuesta vasopresora inducida por el EEP. La nefrectomía bilateral (NFX), la cual reduce los niveles circulantes de ANG, suprimió el incremento de la PAM y de las catecolaminas plasmáticas observada durante el EEP. La administración de una dosis subpresora de angiotensina II restauró la respuesta vasopresora inducida por el estrés en las ratas nefrectomizadas. La modulación de los niveles circulantes de angiotensina II alteró la respuesta presora frente al estrés. Así, la reducción de los niveles circulantes de ANG mediante una ingesta elevada de sodio, inhibió la respuesta presora frente al EEP. Por el contrario, el incremento del sistema renina-angiotensina inducido por una dieta baja en sal, facilitó la respuesta presora frente al estrés. Nuestros resultados indican que la angiotensina II endógena soporta la respuesta simpática frente al estrés, a través de la estimulación de los receptores AT1 presinápticos

ABSTRACT

The purpose of this study was to correlate soybean dust (SD) exposure, skin reactivity to soybean hull (SH) allergens, and symptoms of asthma and/or allergic rhinitis. A group of 365 subjects with asthma and/or allergic rhinitis and a control group of 50 individuals without respiratory symptoms were studied. The level of exposure to SD is defined as follows: 1) direct (DE); 2) indirect (ID), and 3) urban (UE). All subjects completed standard questionnaires. Skin tests with a SH extract and with common allergens were performed by the prick technique (SPT). Fifty-six (15.3


) patients and no subjects from control group had positive SPT (histamine index > or = 0.5) with a SH allergen extract. The percentages of positive SPT to SH extract were 38.7


in subjects with DE, IE and UE, respectively (p < 0.001). Monosensitization to SH was absent in all subjects. The percent of subjects with positive SPTs to mites (p < 0.01), pollen (p < 0.01) and molds (p < 0.05) were higher in subjects with a positive SPT to SH versus those with a negative SPT to SH. Sixty-six percent of subjects with DE and 13.6


of subjects with IE or UE reported respiratory symptoms after SD inhalation (Odds Ratio: 12.67 [2.4-74.9], p < 0.001). Compared to subjects exclusively sensitized to mites, patients sensitized to SH presented significantly different clinical characteristics. Soybean production has been increasing in Argentina during the last 20 years, determining an increase in the population exposed to chronic SD inhalation. This fact determines a high risk of sensitization and triggering of respiratory symptoms in atopic subjects. This study demonstrates that there is: 1) a high prevalence of skin reactivity to SH in subjects with asthma and/or allergic rhinitis from Argentina and that this prevalence is associated with the level of exposure to SD, and 2) an association between sensitivity to SH and severity of asthma. Measures to avoid release and inhalation of SD in rural areas from Argentina are needed.
