BACKGROUND Fifteen (+/-)3,4-Methylenedioxymethamphetamine (MDMA) users, who did not show other drug dependencies or prolonged alcohol abuse, and 15 control subjects were included in the study. METHODS Prolactin (PRL) and cortisol (CORT) responses to the serotonergic agonist d-fenfluramine (D-fen), clinical psychobehavioral changes, and psychometric(More)
Neurotransmitter-neuroendocrine and cardiovascular responses to the administration of a psychologically stressful mixed-model test (Mental Arithmetic, Stroop Color Word Interference Task, Trier Social Stress Test) were examined in 20 male peripubertal subjects affected by anxiety disorder (group A: 14 with generalized anxiety disorder, 6 with generalized(More)
Correlations between sensation-seeking (SS) personality dimension and plasma concentrations of norepinephrine (NE), epinephrine, and NE-dependent testosterone (T), cortisol and prolactin (PRL) were studied in 74 physically and psychologically healthy male volunteers, in order to see whether or not the noradrenergic system is involved in the modulation of(More)
Previous studies of hormonal and neurophysiological changes in response to psychological stress in humans have produced contrasting findings due to differing experimental procedures and consistent individual variability. Habituation effects, which influence physiological coping in response to exposure to repeated stress, need to be investigated more(More)
PURPOSE Studies investigating temperament traits of drug abusers and their biological correlates have disclosed high rates of novelty seeking (NS) in opiate addicts, possibly based on dysfunctions of the dopaminergic (DA) system. The aims of the present study were to see whether or not the monoamine functions were impaired in detoxified addicts and whether(More)
Studies investigating temperament traits in humans and their biological correlates have found high levels of novelty seeking (NS) linked with dopaminergic system changes, and particularly a deficit of dopamine transporter. Harm avoidance and reward dependence, on the other hand, appeared to be associated, respectively with serotonin and noradrenaline(More)
OBJECTIVES With the increased use of trans-scrotal ultrasonography, the unexpected detection of nonpalpable hypoechoic testicular lesions has become more frequent. The different approaches vary from radical orchiectomy to simple ultrasound follow-up, but definitive guidelines do not yet exist about the management of these lesions. We report our series of(More)
A variety of detoxification methods have been utilized for the treatment of heroin withdrawal before individuals begin long-term opiate-free and naltrexone programs. While methadone in decreasing doses is still widely used for detoxication procedures, rapid and ultrarapid protocols including clonidine and opiate receptors antagonists have been proposed.(More)
OBJECTIVE To evaluate the outcomes, the patients', and their partners' satisfaction concerning the AMS Spectra penile prosthesis implantation. METHODS Twenty-two unresponsive or dissatisfied patients with phosphodiesterase 5 inhibitor oral therapy or prostaglandin intracavernous injection underwent a Spectra penile prosthesis implantation. No major(More)
A cohort of 20 patients with delayed priapism who underwent treatment at the Emergency Department of our academic referral centers between January 2002 and April 2010 was studied. Of these, 16 cases suffered from a low-flow priapism. A total of 6 cases were managed non-surgically, 10 required shunt surgery, and of these 5 were treated by early penile(More)
