BACKGROUND The precise characterisation of a high risk status for the development of a psychiatric disorder and the question of how well this predicts disease manifestation is of major importance as negative consequences of late diagnosis and treatment have been well demonstrated. In the absence of well defined and disease specific biological markers for(More)
The prevalence and severity of chronic pain after video-assisted thoracic surgery for pulmonary resection remains to be defined. Three hundred forty-three of 391 consecutive patients 3 to 31 months after pulmonary resection by lateral thoracotomy (n = 165) or video-assisted thoracic surgery (n = 178) responded to a questionnaire aimed at comparing the(More)
OBJECTIVE The burden of depression represents the most debilitating dimension for the majority of patients with bipolar disorder and dominates the long-term course of the illness. The purpose of this manuscript is to review the evidence base of the available treatment options for bipolar depression within two frequent clinical scenarios. METHODS The(More)
BACKGROUND Patients with diffuse pulmonary infiltrates often require biopsy for a diagnosis. Standard operative therapy, open wedge resection via thoracotomy, is associated with known morbidity. We hypothesized that closed thoracoscopic wedge resection may result in reduced morbidity and decreased duration of hospital stay. This retrospective study compares(More)
BACKGROUND Considering results from the early recognition and intervention in psychosis, identification and treatment of individuals with at-risk states for the development of bipolar disorders (BD) could improve the course and severity of illness and prevent long-term consequences. Different approaches to define risk factors and groups have recently been(More)
One hundred thirty-eight consecutive, nonrandomized patients, with equivalent demographic and preoperative physiologic parameters, underwent either a video-assisted thoracic surgical (VATS) approach (n = 81) or a limited lateral thoracotomy (LLT) approach (n = 57) to accomplish pulmonary resection for peripheral lung lesions (< or = 3 cm in diameter). Wedge(More)
Nutritional support in patients with advanced cirrhosis is difficult due to protein, fluid and salt restrictions. Successful liver transplantation should improve nutrient tolerance. We randomly assigned 28 hypoalbuminemic cirrhotic patients to receive, immediately after liver transplantation, one of three regimens: group 1, no nutritional support (n = 10);(More)
BACKGROUND Environmental conditions early in life may imprint the circadian system and influence response to environmental signals later in life. We previously determined that a large springtime increase in solar insolation at the onset location was associated with a younger age of onset of bipolar disorder, especially with a family history of mood(More)
BACKGROUND In a previous meta-analysis of randomized controlled trials comparing lithium with placebo as a long-term treatment in bipolar disorders, we observed a clear preventative effect for manic episodes; however, the effect was equivocal for depressive episodes. Since then, the evidence base has grown further. In this update, we furthermore present the(More)
