   Sammanfattning : The monoamines serotonin and dopamine are likely to be involved in the pathophysiology of social anxiety and other affective disorders, but their respective contributions and putative interactions in the causes and cures of these disorders are still not well understood. It is also largely unknown if and how expectations of treatment success affect brain neurochemistry and neural activations, and if expectations interact with antidepressants like selective serotonin reuptake inhibitors (SSRIs).

   Sammanfattning : In a retrospective follow-up study, n=202, long-term pain relief (>6 months) after a course of acupuncture treatments was found mainly among patients with chronic nociceptive pain while patients with neurogenic or psychogenic pain did not benefit much. In a placebo-controlled randomised single-blind long-term study with independent observer of chronic nociceptive low back pain, n=50, it was found that acupuncture, was significantly superior to true placebo in all outcome measurements, even more than 6 months after the treatment series.

4. 3. Obsessive-compulsive disorder, serotonin and oxytocin : treatment response and side effects

   Författare :Mats B. Humble; Ingemar Engström; Lars von Knorring; Lars Kjellin; Lil Träskman-Bendz; Örebro universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adverse effects; Obsessive-compulsive disorder; Orgasm; Oxytocin; Randomised controlled trial; Rating scale; Response prediction; Serotonin; Serotonin uptake inhibitors; Sexual function; Psychiatry; Psykiatri;

   Sammanfattning : Obsessive-compulsive disorder (OCD), with a prevalence of 1-2 %, frequently leads a chronic course. Persons with OCD are often reluctant to seek help and, if they do, their OCD is often missed. This is unfortunate, since active treatment may substantially improve social function and quality of life. LÄS MER

5. 4. Severe angina pectoris and spinal cord stimulation. Long-term effects and safety aspects

   Författare :Olof Ekre; Göteborgs universitet; []
   Nyckelord :Angina pectoris; Epidemiology; Spinal cord stimulation; Quality of life; Mortality; Health care costs; Electromagnetic interference; Placebo effects;

   Sammanfattning : Refractory angina pectoris has been defined as coronary artery disease and severe angina, where standard pharmacological and invasive treatment possibilities are exhausted. The epidemiology of this condition is virtually unknown.During the last few decades, additional treatment options have evolved for this condition. LÄS MER

7. 5. Recruitment to multicentre randomised controlled trials in stroke : lessons learnt from the effects trial

   Författare :Eva Isaksson; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Effects;

   Sammanfattning : Randomised controlled trials are the gold standard for evaluation treatments. Nevertheless, recruitment into trials is still challenging and many trials fail to meet their recruitment goals within the predetermined time. Less than one third of the trials managed to recruit according to their original plan. LÄS MER
