Drug craving, the irresistible urge for drug intake, is being discussed as a central construct for the explanation of addictive behaviour and for relapses so far only in substance-related addiction. Based on learning models for the maintenance of addiction, in this study, cue-induced craving and psychological variables that influence craving were investigated in subjects with excessive rewarding behaviour such as pathological gambling. Based on the cue-reactivity paradigm, pathological gamblers and healthy controls were exposed to gambling and other cues. Emotional processing of the gambling cues, cue-induced craving, and the influence on craving of depression, anxiety, and stress-coping strategies were investigated. The results demonstrate disorder-specific processing of cues in pathological gamblers, even after abstinence for more than a year. In addition, craving is influenced by psychological disabilities. Data are discussed with respect to comparable data in studies about substance-related addicts.
STUDY DESIGN: Semistructured interview. OBJECTIVES: To assess the degree of participation in sexual intercourse of a sample of women with spinal cord injury (SCI) in our community, to establish to what extent their sexual lives have been affected in comparison to before the injury, and to search for those factors that may have a major influence on both aspects. SETTING: Spinal Cord Injuries Unit, A Coruna, Spain. PARTICIPANTS: A total of 37 women, average age 40 years, time since onset average 10 years. RESULTS: In all, 62% claimed regular sexual activity after the injury. The women who suffered the injury before reaching the age of 18 years run a higher risk of not having physical relationships than those who were above that age when they incurred the SCI (P=0.04, OR 4.75). We discovered a significant drop in the frequency of intercourse (P=0.003) and the ability to reach an orgasm (P=0.008), after the injury. Of these women, 69% were satisfied with their current sexual activity and 77.4% considered the information they received from their doctors on the changes the SCI would cause in their sexuality to be either insufficient or nonexistent. CONCLUSIONS: There is a noticeable decrease in the frequency of intercourse as well as a significant reduction in the capability of reaching orgasm. Despite these changes and problems that ensue during intercourse as a result, most show satisfaction with their current sexual lives. On the other hand, the occurrence of the injury before the age of 18 years may imply a greater risk of not having an active sex life in adult years. We consider it is essential to provide the appropriate sexual information during the process of rehabilitation, aimed at helping women with SCI to adapt to their new situation.
Perinatal asphyxia may induce major neurological deficits shortly after birth as well as neurological/behavioural disorders later in development. We used a rat model of global perinatal asphyxia to model acute intrauterine asphyxia around the time of birth. Caesarean section was performed in rats and their pups, still in uterus horns, were placed into a water bath at 37 degrees C for periods of 0, 10 or 20 min. Pups were then given to surrogate mothers, and examined for long-term behavioural effects of the perinatal asphyctic insult. Behavioural assessment included analysis of novelty seeking behaviour at adolescence, while spatial discrimination abilities, response to both an acute and a chronic stress, and the effects of the full D1 receptor agonist SKF 82958 on open field behaviour were assessed at adulthood. Overall, no marked abnormalities were found in the novelty seeking test, in the ability to discriminate spatial changes in the test environment and in physiological response to stress. However, adult rats subjected to severe perinatal asphyxia (20 min) showed lower activity level and lower stereotyped behaviour after the administration of SKF 82958 in an open field test. These results support the observations from human and animal studies that perinatal insult can produce long-term dysfunction of dopaminergic neurotransmission, and points to the need of more thorough examination of the potential effects of perinatal asphyxia on hypothalamic-pituitary-adrenal (HPA) axis. Altogether, the present findings suggest that the present 20 min perinatal asphyxia model might serve for the study of neurodevelopmental disorders associated with perinatal insults.
