Maintenance cognitive-behavioral therapy and manualized psychoeducation in the treatment of recurrent depression: a multicenter prospective randomized controlled trial.

OBJECTIVE: This multicenter study compared the relapse and recurrence outcomes of two active treatments, maintenance cognitive-behavioral therapy (CBT) and manualized psychoeducation, both in addition to treatment as usual, in patients in remission from depression. METHOD: This was a multicenter prospective randomized observer-blinded study with two parallel groups. The authors assessed 180 patients with three or more previous major depressive episodes who met remission criteria over a 2-month baseline period and who were randomly assigned to 16 sessions of either maintenance CBT or manualized psychoeducation over 8 months and then followed up for 12 months. The main outcome measure was time to first relapse or recurrence of a major depression, based on DSM-IV criteria, as assessed by blinded observers with the Longitudinal Interval Follow-Up Evaluation. RESULTS: Cox regression analysis showed that time to relapse or recurrence of major depression did not differ significantly between treatment conditions, but a significant interaction was observed between treatment condition and number of previous episodes (<5 or ≥5). Within the subsample of patients with five or more previous episodes, maintenance CBT was significantly superior to manualized psychoeducation, whereas for patients with fewer than five previous episodes, no significant treatment differences were observed in time to relapse or recurrence. CONCLUSIONS: The results indicate that maintenance CBT has significant effects on the prevention of relapse or recurrence only in patients with a high risk of depression recurrence. For patients with a moderate risk of recurrence, nonspecific effects and structured patient education may be equally effective.

[Automutilation with indistinct underlying disease--difficulties of care in the community]. / Selbstverstümmelung bei unklarem Grundleiden--Schwierigkeiten der ambulanten Weiterversorgung.

INTRODUCTION: Self-mutilation is well-known in various psychiatric diseases and represents a challenge for forensic pathologists as regards the differentiation of accidental versus self-inflicted injuries, especially when a criminal charge is likely to emerge. METHOD: A case of extraordinarily severe self-inflicted injuries is presented as well as the related implications concerning clinical and ambulatory care for patients, whose underlying motivation remains unknown. RESULTS: A 60 year-old worker exhibited an open scull fracture and 14 abdominal wounds with protrusion of small intestine, from which a part of 160 cm length was completely removed beforehand. The patient claimed the wounds having been caused accidentally. When examined by a psychiatrist, disturbances in orientation, unrest and ill concentration were found, but no symptoms related to psychosis, depression or suicidal behaviour. DISCUSSION: Although the need for more detailed examination seemed to be clearly evident, the medical authorities did not take action. Consequently, no further psychiatric treatment was initiated. The implications of this case on the background of the literature are discussed.

Sleep apnea and occupational exposure to solvents.

OBJECTIVES: The possible effects of exposure to neurotoxic substances such as gasoline, diesel fuel, paint, varnish, and solvents on the pathogenesis of obstructive sleep apnea were examined. METHODS: Four hundred and forty-three persons with incident obstructive sleep apnea were recruited within the framework of a case-referent study. A reference population (N=397) was included as the first reference group. In addition 106 patients whose sleep laboratory findings confirmed that they were not suffering from obstructive sleep apnea were then included as a second reference group. Data were gathered with a questionnaire which had to be filled out by the persons with obstructive sleep apnea (cases) and the referents themselves. In the assessment of occupational exposure the questionnaires were filled out by the subjects themselves, and a job-exposure matrix was also used. Data were analyzed using logistic regression to control for age, region, body mass index, cigarette smoking, and alcohol consumption. RESULTS: None of the exposures were statistically significantly associated with obstructive sleep apnea. There was no correlation with occupation. Only current activities in service occupations revealed an increased odds ratio, 1.6 (95% confidence interval 1.1-2.4). CONCLUSIONS: No suggestion was found of an association between exposure to solvents and obstructive sleep apnea.
