Uso y utilidades clínicas del pletismógrafo en la evaluación de la respuesta sexual masculina: Ejemplificación a partir de tres casos

El pletismógrafo peniano es un instrumento que nos permite medir cambios en el diámetro del pene a partir de la exposición a estímulos elicitadores de la respuesta sexual. A pesar de las demostradas utilidades clínicas y empíricas de este instrumento, su uso todavía no se ha generalizado. Por ello, dedicamos este trabajo a ejemplificar el procedimiento a seguir para su aplicación y algunas de las utilidades clínicas que de él se derivan. Para ello recurriremos al análisis de tres casos clínicos; el primero de ellos, un joven con una elevada frecuencia de actividad sexual y de consumo de cibersexo; el segundo, el caso de un chico que a pesar de identificarse como heterosexual, mantiene relaciones sexuales con personas de su mismo sexo: finalmente, analizaremos el caso de otro chico con rasgos de compulsividad sexual. En los tres casos, la aplicación del pletismógrafo complementa una evaluación clásica de la conducta sexual y supone un elemento crucial en el análisis de cada caso.The penile plethysmograph is an instrument for measuring changes in the diameter of the penis after exposure to stimuli elicitors of sexual response. Despite the demonstrated clinical and empirical utility of this instrument, its use is not yet widespread. For this reason, we dedicate this paper to illustrate the procedure for application and some of its clinical utilities. For this purpose, we analyze three cases; the first case, a young man with a high frequency of sexual activity and consumption of cybersex; the second, the case of a boy who self-identifies as heterosexual but has relations with same sex people; finally, we discuss the case of another boy with sexual compulsivity traits. In all three cases, the penile plethysmograph complements classical assessment of sexual behavior and it’s a crucial element in the analysis of each case.Este trabajo ha sido financiado por el proyecto de investigación del Ministerio de Ciencia e Innovación (psi2011-27992 / 11 I 384)

HIV-Risk Index: Development and Validation of a Brief Risk Index for Hispanic Young People

The prevalence of HIV risk behaviors among young people facilitates the spread of HIV, in particular regarding unsafe sex behavior, although this trend is different within this population. For this reason, identifying the riskier young population is required to prevent HIV infection. The main purpose of this study was to develop and validate a risk index to assess the different sexual HIV risk exposure among Hispanic Young people. For this purpose, 9861 Spanish young people were randomly distributed into two groups (derivation and validation group). According to the results, the factor analyses grouped the nine items of the HIV- risk index into two factors (factor 1, direct sexual risk indicators and factor 2, indirect sexual risk indicators) with an equal structure for men and women by a multi-group confirmatory factor analysis. The variance explained was 54.26 %. Moreover, the Cronbach’s alpha coefficient revealed high internal reliability (α = .79) and the convergent validity supported its evidence based on different HIV risk indexes. Therefore, the HIV-risk index seem to be a rigorous and valid measure to estimate HIV risk exposure among young people.The authors acknowledge young people who have participated in our studies during these years, as well as some colleagues who have contributed to them such as Maite Edo, Mª Carmen Guirado, Jose Miguel Bravo, Sandra Gómez and Cristina Cassà.

Cybersex Addiction: A Study on Spanish College Students

The aim of this study was to determine type and frequency of online sexual practices among Spanish college students, prevalence of risk and pathological cybersex use profiles, and correlates/predictors of this behaviour. Participants were 1,557 males and females between 18 and 25 years old. Results showed that cybersex use is not as frequent as that documented in other Western countries. However, a significant percentage of participants with a risky (9%) or pathological (1.7% in men and 0.1% in women) profile was identified. Finally, we found a set of variables that, in interaction with gender, explains 58% of the variance for cybersex addiction scores

Relationship Status as an Influence on Cybersex Activity: Cybersex, Youth, and Steady Partner

The authors focus on the influence of participants’ having or not having a steady partner when reference to cybersex use. Participants were 1,239 young, Spanish individuals who completed the Internet Sex Screening Test. Results showed the influence of being in a relationship on certain consumption dimensions of cybersex; the influence was found to be greater in men than in women. In general, cybersex activity was higher for single participants, although it was also significant for participants with a steady partner. The authors’ findings facilitate the comprehension of the effect of new technologies in intimate human relationships

Malignant external otitis and mastoiditis associated with an IgG4 subclass deficiency in a child.

We have presented the first child in Delaware with malignant external otitis associated with IgG4 deficiency. Our patient needed three courses of intravenous antibiotics and twice required mastoidectomy, but has recovered completely following the restoration of the natural barrier between the internal and external ear, using a fascial graft from the large temporalis muscle. Some hearing deficit remains
