A relationship has been suggested between clinical presentation of paraphilias and obsessive-compulsive disorder (OCD) with respect to the unwanted repetitive nature and insight into the ...irrationality of the paraphiliac behavior. This has led to speculation that paraphiliac disorders might belong to an "obsessive compulsive spectrum." To address this issue, and because of the striking selective benefit of serotonin reuptake blocking antidepressants (such as clomipramine) in the treatment of OCD, 15 paraphiliacs entered a double-blind crossover comparison of clomipramine vs. desipramine preceded by a 2-week single-blind placebo period. Four subjects responded to placebo and were dropped from the study. Three others failed to complete the study. Although the study is limited by the small number of patients and the heterogeneity of the paraphilias, the observed benefit from both tricyclics (over the initial placebo) encourages further study. For the 8 subjects completing the protocol, there was no preferential response to the more specific serotonin reuptake inhibitor suggesting a difference in underlying pathophysiology between paraphilia and OCD.
Issues that healthcare leaders should consider in determining whether to develop a teleintensivist program to support physician coverage in the ICU include those related to: Coverage. Scope. IT ...capabilities. Licensure of participating physicians and accreditation of the hospital. Payment. Potential impact on other ICU services. Performance measurement. Training and education.
The administration of l-dopa suppresses prolactin (PRL) secretion in normal subjects and in patients with hyperprolactinemia, although it is not known whether this effect, which requires the ...conversion of dopa to dopamine, is mediated peripherally or through the central nervous system. To distinguish between these effects, 10 normal subjects (6 male, 4 female) and 8 patients with hyperprolactinemia associated with pituitary tumors were given l-dopa, 0.5 g alone, or 0.1 g after a 24-h pretreatment with carbidopa, 50 mg every 6 h, which produces peripheral dopa decarboxylase inhibition. Similar degrees of PRL suppression were observed in normal subjects (basal plasma PRL 13+/-2 ng/ml) after l-dopa alone (48+/-4%) and after l-dopa plus carbidopa (58+/-6%). In patients with pituitary tumors and elevated plasma PRL (73+/-14 ng/ml), l-dopa alone led to PRL suppression comparable with that in normal subjects (47+/-6%). However, l-dopa plus carbidopa resulted in only minimal suppression of plasma PRL (19+/-4%) which was significantly less than after l-dopa alone (P < 0.001). Urinary homovanillic acid excretion, which reflected peripheral dopa decarboxylation was similar in controls and tumor patients after l-dopa both alone and after carbidopa pretreatment. Comparable suppression of PRL levels in response to a dopamine infusion (4 mug/kg per min for 3 h) was observed in controls and tumor patients. The results indicate that although peripheral conversion of exogenous dopa to dopamine can suppress PRL secretion, in normals, the central nervous system conversion of dopa to dopamine in the presence of peripheral dopa decarboxylase inhibition is sufficient to account for its PRL-suppressive effects. In contrast, patients with tumors, while retaining peripheral dopaminergic inhibitory effects on PRL secretion, exhibit a marked reduction of central dopaminergic inhibition of PRL secretion.
A selected review of the literature about short-term therapy and social skills as they may apply to depressed adolescents is presented. Two forms of group therapy are described. These are social ...skills and a traditional discussion group format. Some of the difficulties in establishing and evaluating a group therapy program are outlined.
