ABSTRACT

UNLABELLED: The fact that posttraumatic stress disorder is a very important construct in public health and opinion, especially in the United States of America, has veiled it dubious specificity and problematic universality. HYPOTHESIS: the abandon of Freudian theory since 1980 was correlative of a permanent revision of criteria to define "traumatic" in DSM versions, as well as of revaluation of ancient theory of dissociation. METHOD: most meaningful changes introduced in PTSD criteria are critically reviewed from DSM-IV to DSM-5. "Traumatic", symptoms and dissociative estates, and a new preschool children subtype are revised. CONCLUSION: "Traumatic" yet being an artificial criterion is steel needed in order to keep the construct as a whole. Dissociative estates occupy an important place for the American authors and have turned more visible in DSM-5 than in previous DSM. New chapter "Trauma and stressor disorders" and new descriptions about PTSD support an enlarged clinical view of "traumatic". Inconsistencies found between reviews considered for PTSD in DSM-5 show that different work groups contribute to the construction of the disorder with fragmentary and divorced parts from one another.

ABSTRACT

The Research Domain Criteria (RDoC) is an initiative of the National Institute of Mental Health of the United States of America, which based on research purposes consists of a new way of classifying mental disorders. His raison d’Ûtre is based on the conclusion that the knowledge progress of neurosciences does not seem to confirm the validity of the conventional psychiatric diagnoses. Furthermore, researching based on such diagnoses would weaken the progress in Psychiatry. Besides these scientific reasons, the Research Domain Criteria project is born within a political framework, giving raise to economic tensions. The objective of this paper is to discuss the first issue without avoiding the second one.

ABSTRACT

Antecedentes: los antiinflamatorios no esteroides (AINE) producen mayoritariamente reacciones pseudoalérgicas, es decir no mediadas por IgE. Distintos mecanismos de secreción se han propuesto para reacciones alérgicas y anafilactoideas. Objetivos: comparar los resultados de la activación de basófilos en presencia de diclofenac por medio de microscopia óptica (test de degranulación de basófilos (Ba humanos, TDBH) y citometría de flujo (CF) (TAB) en pacientes sensibles a aspirina, a fin de poder sugerir un posible mecanismo de activación. Métodos: el TDBH se realizó mediante coloración con azul de toluidina en células mononucleares. Para el TAB se utilizaron la marcación con anti-IgE/anti-CD45 para identificar los Ba y la expresión de CD63 para evaluar la activación. Se registró el porcentaje de Ba activados en cada caso después de la estimulación con la droga. Se investigó la respuesta a 1 µg/mL y 10 µg/mL de diclofenac en 8 pacientes con historia clínica de sensibilidad a aspirina y en 8 controles. La estimulación con fMLP fue el control positivo de la reacción. Resultados: 8/8 pacientes presentaron TDBH positivo para ambas dosis de diclofenac (X ± DE:42,6 ± 14,6 por ciento para 1µg/mL; y 45,65 ± 14,3 por ciento para 10 µg/mL) con diferencias significativas respecto del grupo control (X ± DE: 10,23 ± 3,36 por ciento y 17,74 ± 6,49 por ciento para 1 y 10 µg/mL, respectivamente). El TAB fue negativo en 7/8 pacientes pero 1/8 tuvo una respuesta leve (7,2 por ciento). Los porcentajes de Ba activados después de la estimulación con fMLP fueron similares en ambos grupos estudiados y con ambas técnicas empleadas. Conclusión: los AINE inducen, en pacientes sensibles, degranulación de Ba a través de mecanismos diversos que pueden o no incluir la extrusión de los gránulos citoplasmáticos
