ResumenEl Strongyloides stercoralis (Ss) es un nematodo end emico en países de clima tropical y subtropical, y en España se han descrito casos, sobre todo en la costa mediterr anea. La infección por Ss suele ser asintom atica o manifestarse por síntomas predominantemente digestivos, y en los casos de hiperinfestación produce una estrongiloidiasis diseminada con sobreinfecciones bacterianas sist emicas que provocan una disfunción multiorg anica con resultado letal. Los factores de riesgo m as importantes para que una infección en principio intestinal y en muchas ocasiones asintom atica adquiera características de gravedad son la inmunosupresión y la utilización de corticoides, por su capacidad de alterar la función eosinofílica. El caso que presentamos corresponde a la forma de síndrome de hiperinfección por Ss acompañado de neumonía bilateral que ocasionó síndrome de distr es respiratorio agudo, con demostración del par asito en muestras de esputo, jugo g astrico y heces en un paciente con enfermedad de Crohn y tratamiento crónico con corticoides.
AbstractStrongyloides stercoralis (Ss) is an endemic nematode in tropical and subtropical countries. Cases have also been described in Spain, major mainly in the Mediterranean coast. Ss infection is usually asymptomatic or causes mild gastrointestinal symptoms. Spillover infection can cause widespread disseminated strongylodiasis associated to severe systemic bacterial infections which may lead to multiorgan failure and death. The most important risk factors that may convert an infection that is basically intestinal and often asymptomatic, to severe entity, are immunocompromised conditions and corticosteroids therapy, due to their effect on the eosinophil function. We report a case of a patient affected by Crohn's disease in chronic treatment with corticosteroids who developed a Ss hyperinfective condition with pulmonary involvement ARTICLE IN PRESS 0210-5691/$ -see front matter & 2009 Elsevier España, S.L. y SEMICYUC.

Romantic jealousy is one of the most complex emotions people experience in their relationships; people may reach high levels of violence as a result of pathological jealousy. This paper sought to adapt to Spanish language use and examine the psychometric properties of the Interpersonal Jealousy Scale (IJS). This scale evaluates the negative emotion resulting from actual or threatened loss of a loved one to a rival. We used a Colombian sample of 603 Colombian adults (59,03% women). Factor models were tested by Confirmatory Factor Analysis (CFA), in order to confirm the stability of the internal structure of the scale. The CFA supported the robustness of a one-dimensional structure with 18 items. Good internal consistency and evidence of external validity were found, as well as adequate adjustment parameters under the item response theory. In the analysis of the differential functioning of the items by sex, five items measured the different latent trait in men and women. The data indicate that the revised Spanish version of the IJS is a useful instrument to assess romantic jealousy.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
