RESUMEN
BACKGROUND: We examined whether somatic symptoms reported by patients with bipolar spectrum disorder (BSD), in this study defined as bipolar II (BD-2) or recurrent brief depression with (RBD-H) or without (RBD-O) a history of hypomanic symptoms might point to the possible underlying disease markers (endophenotypes). We hypothesized that somatic symptoms that are possible indirect indicators of endophenotypes should be more prevalent among patients than among healthy controls; should not correlate with neuroticism; should not correlate with the severity of current mental status (e.g., anxiety, depression); and should not correlate with the use of psychotropic drugs including antiepileptics or be explained by co-morbid medical diseases. METHODS: Sixty-one patients (BD-2: n=21; RBD-H: n=19; RBD-O: n=21) were compared with 21 healthy controls. Assessments included a 123-item somatic symptom checklist; assessments for neuroticism, anxiety and depression. Candidate somatic symptoms were selected using a 4-step inclusion/exclusion procedure. RESULTS: Seven symptoms survived in all three groups: general (fatigue, feeling exhausted); sensory (leaden sensation in legs, pain in the body, impaired sense of smell); cognitive (loss of memory) and autonomic (excessive perspiration). In addition 15 symptoms survived in one or two groups (examples: impaired hearing, hypersensitivity to sound, inability to find words). LIMITATIONS: Possible selection bias and small sample size precludes firm conclusions with regards to specific symptoms. CONCLUSION: Our approach identified symptoms for which an association with BSDs has been suggested previously, as well as symptoms not commonly associated with BSDs. The findings support the feasibility and validity of using assessment of somatic symptoms as an approach to identify potential endophenotypes in BSDs.

BACKGROUND: We compared ICD-10 psychiatric disorders in female patients with fibromyalgia (n=45) or functional dyspepsia (n=18) with age-matched random sample controls (n=49). METHOD: Version 2 of The Schedules for Clinical Assessment in Neuropsychiatry (SCAN) was used for present state examination and lifetime diagnoses. RESULTS: Current psychiatric disorders (somatoform pain disorder and specific phobia omitted) were diagnosed in 80% of fibromyalgia patients (OR=8.3), 83% of functional dyspepsia patients (OR=10.3) and 33% controls. Among fibromyalgia patients 27% had lifetime panic disorder. Lifetime mood disorders were found in 83% of functional dyspepsia patients. First-degree relatives with psychiatric disorder were found in 16% of the fibromyalgia patients, 50% of functional dyspepsia patients and 20% of controls. CONCLUSIONS: Fibromyalgia is associated with panic disorder and functional dyspepsia with mood disorders in substantial subgroups. Psychiatric symptoms and somatic complaints are closely related in these disorders.

The aim of the present study was to assess the use of consultation-liaison psychiatry in Norway, the resources used, the organisation and quality of the services, and whether there is a need to increase the services and improve the education. A questionnaire was mailed to all the major somatic and psychiatric departments in Norway. The questionnaires were completed and returned by 189 somatic departments (85%) and 74 psychiatric departments (55%). Each psychiatric department gives a median of two consultations each week (range 1-13). A minority of the consultations are with a specialist in psychiatry. About 60% of the psychiatric departments offer supervision of younger doctors. Psychiatric evaluation is seldom carried out when the somatic diagnosis is unclear. Most of the somatic departments are satisfied with the services. Both the somatic and psychiatric departments express a need for more extensive services and more education in medical psychology.
