Carbamazepine, a drug that is clinically effective in paroxysmal pain syndromes and in epilepsy, also appears to be effective in the treatment of manic-depressive illness. The mechanisms of action of carbamazepine and its endocrine effects remain unclear. Therefore, the hormone responses to sequential stimuli--namely, arginine, thyrotropin-releasing hormone (TRH), and luteinizing hormone-releasing hormone--were studied in six patients with major depressive disorder before and during treatment with carbamazepine. The drug was found to blunt the thyrotropin-stimulating hormone response to TRH and to augment the prolactin response to arginine. The advantages of the experimental design and the implications of the findings for carbamazepine's mechanism of action in affective illness are discussed.

The relationship between chronic pain and depression has become enmeshed in the literature. In an attempt to unravel the relationship between chronic pain and depression, the authors studied a uniform group of 80 chronic back pain patients with and without depression using the dexamethasone suppression test (DST). The DST examines the hypothalamic response to an exogenously administered steroid (dexamethasone) challenge. In normal subjects and patients without major depression, the dexamethasone suppresses the release of cortisol from the adrenal glands. In 40% of patients with major depression, there is an early escape of cortisol from dexamethasone suppression. We found that 40% of patients with a DSM-III major depression (dysphoric mood, appetite and sleep changes, loss of energy and interest, decreased concentration, suicidal ideation, and feelings of self-reproach) were non-suppressors and none of the patients without major depression showed this abnormality. These findings suggest that the concept of chronic pain as a variant of depression might be an oversimplification.

Cerebrospinal fluid (CSF) levels of beta-endorphin (beta-EP) were measured in 9 migraineurs with interparoxysmal headache (MIH), in 13 patients with major depression in an active phase (5 suffered from MIH), and in 16 age-matched controls. beta-EP was measured by specific RIA after gel-chromatography. While beta-EP levels of depressed patients (58.5 +/- 21.0 fmol/ml, M +/- SD) were similar to those of controls (65.8 +/- 26.6), those of migraineurs (15.0 +/- 11.1) were significantly reduced (p less than 0.01). In depressed patients also suffering from MIH, beta-EP concentrations (22.8 +/- 7.2, p less than 0.05) were half those reported in depressed patients without pain problems. The reduced CSF beta-EP levels in patients whose headache and depression coexist support the notion that this neuropeptide is concerned with chronic pain, independently of the affective state.

An association between chronic pain and depression has been recognized for a long time. However, the exact nature of this relationship remains unclear. The authors studied 71 patients for affective disorders and schizophrenia-lifetime version (SADS-L). Based on the interviews, we were able to identify 31 patients with major depression, 8 patients with minor depression and 18 with intermittent depressive disorder as defined by Research Diagnostic Criteria. Item analysis using the Hamilton Depression Rating Scale and the Montgomery-Asberg Depression Rating Scale showed that the items did not discriminate in patients with major depression the presence of organic findings. However, most of the items significantly discriminated between the various types of depression and patients without depression. The occurrence of clearly defined depression points to several avenues of research aimed at clarifying the incidence etiology and treatment of depression in these patients.

The relationship between anxiety and chronic pain has been poorly studied. The authors studied the occurrence of symptoms of anxiety in chronic low back pain patients. Anxious mood and other symptoms of anxiety were commonly seen in patients with chronic low back pain. Symptoms of anxiety were more common in patients with depression, especially those with major depression. Anxious mood, tension and general somatic symptoms of the sensory type were more common than any other type of anxiety symptoms. The authors discuss the potential role of anxiety in chronic pain patients.

The ethics of psychosurgery involve questions of moral philosophy and pragmatism in alleviating human suffering. The weighing of scientific data along with philosophical oughts and shoulds is required. The medical literature indicates definite efficacy for some kinds of limbic surgery, mainly cingulotomy and capsulotomy, in some kinds of conditions, namely major depression, pain and anxiety. The relative utility of these procedures given the severity of the illnesses and the safety of the procedures described is significant. Ethical and moral conflicts over altruism, autonomy and suffering require recognition before their due considerations (Kleinig 1985). The following recommendations emerge from these considerations: 1. No consideration of ethics in psychosurgery is complete without consideration of both the scientific data and moral conflicts. 2. The considerable efficacy and safety of cingulotomy and capsulotomy must be acknowledged. 3. Indications and contraindications do exist for selecting patients. Major psychiatric Axis I diagnoses of depression and anxiety are the indications. Personality disorders are not indications. 4. Peer review, unfettered consent and knowledge of the psychodynamics of severe illness are three ingredients necessary for wise decisions about performing limbic surgery. 5. The liberal advocation of autonomy without responsibility is an amoral, not liberating, point of view. 6. Politics should be denounced as the most serious ethical problem in medical decision making. Political intrusion into the scientific matters and the doctor-patient relationship has created ethical problems with psychosurgery and continues to do so today.

In the present study of 253 patients with chronic pain syndrome we have made a multidimensional approach. All patients have been included in the study independent of coexisting states of anxiety or depression. We included criteria for diagnosis, duration, generability and intensity of pain, anxiety and depression, psychosocial stressors and social functioning. Using this system we have evaluated the antipain effectiveness of clomipramine and mianserin in a double-blind, placebo-controlled trial. By use of the Melancholia Scale 16 patients (6%) had a major depression, and by use of the Hamilton Anxiety Scale, 72 patients (28%) had a generalized anxiety disorder. The results showed no statistically significant difference between the three treatments, when using a visual analogue scale (VAS 10 cm with cut-off score 2 cm) for severity of pains as outcome criteria or the results of VAS and Global Clinical Impression Scale using the criteria of reduction of 50% or more between the pretreatment and posttreatment scores. By use of all the assessments it is possible to make an improvement curve for each patient expressed by the area under the curve, and not even there we found a difference between the three treatments. Clomipramine and mianserin were significantly superior to placebo in the topographical pain subgroup with headache using area under the improvement curves as criteria (p less than 0.05). When the 60-item General Health Questionnaire was used to identify minor psychiatric morbidity 44% was found. We can use this as a measure of quality of life. Our results have indicated that placebo-controlled studies are still needed in this field of research.

Recent studies have shown that depression can be assessed in patients who have chronic pain. This study shows that various subtypes of depression can be differentiated in such patients using a standardized diagnostic schema for psychiatric disorders and a self-rating instrument for assessing the level of psychologic distress. In addition, when examining the onset of pain and subtypes of depression, there was no correlation between the onset of major depression and pain, whereas there was a strong positive correlation between the onset of chronic depression and pain. The recognition of the subtypes of depression has clinical implications in the management of the patient with chronic pain and depression.

It has been suggested that "fibrositis" or rheumatic pain modulation disorder (RPMD) is a variant of depressive illness. Both disorders are associated with abnormalities in sleep physiology. Since the clinical features of RPMD do not meet all the criteria for a major depressive disorder, the symptoms and sleep physiology in subjects with dysthmic disorder (DSM III criteria) (N = 6), and RMPD (N = 6) were compared, in order to determine the similarity between the two groups. The sleep physiology in dysthymic disorder was first examined over three consecutive nights since a systematic evaluation of the sleep physiology in this group of disorders has not yet been reported. All dysthymic patients showed episodic bursts of high-amplitude (75-150 microvolts) theta (3-5 Hz) bursts in stage 2 sleep, and REM onset latency was abbreviated only on night 2. The theta bursts have not been previously reported, and may be an early marker of disorganization of non-REM sleep in the dysthymic subjects. The comparison of the two groups revealed that RPMD subjects reported more pre- and post-sleep pain (p less than 0.01), lighter sleep (p less than 0.01), and more physical ailments during sleep (p less than 0.01), and had more alpha (7-11.5 Hz) in non-REM sleep (p less than 0.01).(ABSTRACT TRUNCATED AT 250 WORDS)

Depression is a complex, debilitating illness that is frequently present in a medically ill population. Assessment of depression presents a challenge to the nurse practitioner whose patient may not describe a depressed mood, but presents with multiple somatic complaints that do not respond to usual interventions. A two-phase descriptive survey that examined the incidence and severity of depressive symptomatology in 30 women on their initial visits to a general medical clinic is reviewed. In addition to an evaluation of depression, somatic symptoms and demographic data relevant to the assessment of depression were obtained. Fifty percent (15) of the women exhibited symptoms of depression as measured by the Beck Depression Inventory. Significant positive correlations were found between depression, stress, level of somatic symptoms, pain and family history of depression. A chart review was done four months subsequent to administration of the Beck Depression Inventory for data concerning care. Significant negative correlations were found between depression and number of clinic visits. The chart review revealed that the depression experienced by the 15 women was apparently unrecognized and untreated. The diagnostic criteria for major depression and the medical conditions that may present with depressive symptoms are covered to assist NPs in recognizing depression. Drugs that can aggravate an existing depression or cause depression as a side effect are listed. The short form of the Beck Depression Inventory is provided to help NPs uncover hidden depressive symptoms in their clients.
