Tilt testing for syncope.

Vasovagal syncope is a common cause of sudden collapse. It results from inappropriate activation of left ventricular mechanoreceptors causing sudden vasodilation with bradycardia. Tilt testing is an inexpensive and non-invasive way of establishing a vasovagal diagnosis in unexplained syncope. If critical care nurses improve their understanding of the pathophysiology of vasovagal syncope and the procedure of tilt testing, their care of syncopal patients will be enhanced. This literature review discusses the pathophysiology and clinical presentation of vasovagal syncope. The procedure of tilt testing is explained and the treatment of vasovagal syncope is briefly reviewed.

Sadism and other paraphilias in normal controls and aggressive and nonaggressive sex offenders.

Penile circumference responses (PCRs) to a visual age/gender erotic preference battery were analyzed from 60 normal controls and 227 sexual offenders. Sixty offenders were classified as sexual aggressives on the basis of their behavior and damage to their victims. The mean PCR to sadism slides (visual portrayals of nonsexual violence against fully clothed females) was significantly larger for the sexually aggressive group compared to the sexual nonaggressive offender and normal control groups. There were no significant differences in mean victim damage scores between the sexual aggressives who responded significantly to the sadism slides and those who did not. Thus, PCRs were not useful in identifying more from less dangerous sexual aggressives. The incidence of a clinically significant PCR to any of the four paraphilic categories included in the assessment battery was 28, 60, and 65% in the normal controls, sexual nonaggressives, and sexual aggressives, respectively. For sadism, it was 5, 8, and 45% respectively, for these groups. Pedophilia had a low incidence of co-occurrence with other paraphilias whereas sadism, transvestism/fetishism, and the courtship disorder paraphilias had a high incidence of co-occurrence.
