A new antidepressant, amoxapine, which is a dibenzoxazepine deprivative, was compared with amitriptyline in a randomised double-blind trial. Forty-eight patients were included and 41 completed a 4-week treatment. Most of the patients were maintained on 150 mg daily. Assessments were made by the Hamilton Psychiatric Rating Scale for Depression (HAM-D), Nurses' Observation Scale for Inpatient Evaluation (NOSIE), Clinical Global Impression (CGI) scale and Patient's Self-Evaluation. The total HAM-D score was considerably reduced in the majority of the patients. Amitriptyline was the most effective with regard to symptoms included in the factor Sleep Disturbances and-secondary maybe-towards some items included in the factor Somatization. For the remaining items,including the items of the factors Anxiety/Depression and Apathy, the last score was lower in the amoxapine group than in those treated with amitriptyline. Among the unipolar cases the amoxapine treated patients were more satisfied with regard to efficacy (P = 6.3%). The frequency of side effects such as tremor and dizziness was considerably lower in the amoxapine group. In total, the side effects lasted longer in the amitriptyline group. We conclude that amoxapine seems to be an effective antidepressant with a low frequency of side effects.

This study was conducted to evaluate the relationship between the prevalence of subjective symptoms in workers using vibrating tools and the duration of chain saw operation and to examine whether the symptoms were relevant to factors other than the usage of vibrating tools. The statistical model of multivariate analysis was adapted to analyze individual data on the subjective symptoms of 317 chain saw operators. The obtained results were as follows: 1. In analysis of covariance, age-adjusted operating year in workers with peripheral circulatory, peripheral neurological and musculoskeletal disturbances was significantly longer than that without such disturbances. For these disturbances, partial regression coefficients of operating year were significantly high in multiple regression analysis. These results show that these disturbances and age-adjusted operating year are mutually closely related. 2. Multiple regression analysis showed that the partial regression coefficients of both operating year and age were low for nine symptoms, i.e. dulling sense of touch, joint pain, headache, dizziness and/or tinnitus, profuse sweating, discomfort of stomach, palpitation and/or dyspnea, hearing disturbance and lumbago. These results suggest that such symptoms were not related to either age or chain saw operation. 3. The results of principal component analysis were visualized in three-dimensional space in order to evaluate the relationships among the symptoms. The analysis showed that peripheral circulatory and neurological disturbances appeared independently and that general symptoms such as easy fatigability, headache, forgetfulness, vertigo and/or tinnitus, easy irritability, sleep disorder, profuse sweating, discomfort of stomach, palpitation and/or dyspnea, shoulder stiffness, hearing disturbance and lumbago consisted of four independent groups. Each group has no relationship with duration of chain saw operation. This suggests other harmful factors of the groups play a role in the prevalence of the symptoms.

The aim of this study was to evaluate the safety of zimeldine, a 5-HT reuptake inhibitor, in the long-term treatment of depressive disorders. The study was an open label, multicentre investigation involving 147 patients who were suffering from depressive illness and who needed long-term anti-depressant treatment. Sixty-five patients completed the intended treatment period of 1 year, 75 terminated prematurely, and 7 are still in the programme. The reasons for termination were mainly ineffectiveness of the drug and adverse reactions. During the long-term treatment the most common emergent symptoms were, in order of decreasing frequency, dizziness, dry mouth, sleep disorders, sweating, tremor, nausea and headache. The side-effects were, however, mild and they generally decreased during the treatment period. No new adverse symptoms were reported. In the long-term treatment group, body weight showed a slight mean decrease. Clinical chemistry and cardiovascular investigations were judged to show no changes of clinical importance. It is concluded that zimeldine was shown to be a safe drug in this 1-year treatment programme of depression.

In a Finnish general practice 120 patients with psychosomatic disorders, manifest as syndromes of tension headache, cardiac neurosis, dizziness or muscular tension, were randomly allocated to treatment over a 4-week period with either flupenthixol (1 to 2 mg per day) or diazepam (5 to 10 mg mg per day). The 4 syndromes and 12 associated symptoms (anxiety, fatigue, depression, pain, asthenia, muscle fatiguability, tension, dyspnoea, restlessness, palpitations, sleep disorders, and vertigo) were rated on a 4-point scale on entry, at 2 weeks and at 4 weeks. Both drugs reduced significantly the average total scores for syndromes and single symptoms after 2-weeks' treatment. Flupenthixol was the more effective in relieving fatigue and vertigo; diazepam in relieving headache, anxiety, tension, restlessness and sleep disturbance. Cardiac neurosis, palpitations and general muscular tension responded poorly to both drugs. After 4 weeks, relief of vertigo, pain and fatigue was more evident in the flupenthixol group, and of anxiety, tension and restlessness in the diazepam group. Side-effects were complained of at some stage by 17 patients in the flupenthixol group (9 of fatigue, 5 of sleep disturbance, 1 of constipation, 1 of extrapyramidal symptoms, and 1 of weight gain) and by 16 patients in the diazepam group (10 of fatigue, 4 of sleep problems and 2 of diarrhoea).

Outpatients with endogenous depression diagnosed according to the research diagnostic criteria of Feighner et al. were randomly referred to treatment with zimelidine (100 mg b.i.d., group Z) or maprotiline (75 mg b.i.d., group M). Patients who did not respond to treatment by days 28 were crossed over to the other drug. This preliminary report comprises results up to day 28 and includes antidepressive effect as rated by CPRS and globally, side effects, clinical chemistry and ECG. Ratings were double-blind at days 0, 7, 14 and 28, and a washout period of 4--7 days preceeded the trial. Group Z includes 27 and group M 28 patients with equal distribution of sex, age, duration of present episode, initial severity, etiology and previous course. There were 11 dropouts in group M and 5 in group Z due to side effects or treatment failure. On the other hand, 8 patients in group Z had to cross over to the other drug versus 2 in group M. According to the total CPRS score and the global score the antidepressive effect was somewhat better in group Z at 2 weeks but similar at 1 and 4 weeks. Group Z is less sedative but still seems to have a better anti-anxiety effect. Side effects were on a low level. There was a greater number of patients in group Z who complained of nausea, vomiting, loose stools, sleep disorder and sweating, and in group M dry mouth, drowsiness, dizziness and accomodation difficulties. Chemical analyses and ECG showed slight and inconsistent changes.

In recent years research has shown that subsets of patients with mitral valve prolapse also have associated autonomic or neuroendocrine dysfunction that can result in a number of related symptoms, including fatigue, palpitations, chest pain, exercise intolerance, dyspnea, dizziness, headache, sleep disorders, gastrointestinal disturbances, cold extremities, and panic attacks. These patients have been classified as having mitral valve prolapse syndrome. This article discusses the pathogenesis and management of mitral valve prolapse syndrome and serves to make clinicians aware of newer developments in the study of autonomic function and dysfunction.

The efficacy of moclobemide (300-450 mg/day) was compared with fluoxetine (20-40 mg/day) in a double-blind, multicentre study in 209 patients with new episodes of depression selected from 612 consecutive depressed patients representative of those consulting psychiatric services in Finland. Antidepressant efficacy was assessed with the Hamilton Depression Rating Scale (HDRS), Montgomery-Asberg Depression Rating Scale and Clinical Global Impression (CGI). The Medical Outcome Study Short-form General Health Survey (SF-20) and 15D Measure of Quality of Life were used to measure effectiveness in terms of health-related quality of life. Efficacy was evident with both drug treatments, with 67% in the moclobemide group and 57% in the fluoxetine group having a reduction in HDRS of more than 50%. Similarly, 77% of the patients in the moclobemide group and 67% in the fluoxetine group were assessed on the CGI as much better or very much better after 6 weeks of treatment. The most commonly reported adverse events were nausea, other gastrointestinal symptoms, nervousness, dizziness and sleep disorders. Nausea was significantly more common in the fluoxetine group and was found especially in women. Premature terminations of treatment were 18% in the moclobemide and 21% in the fluoxetine group. A significant change for the better in quality of life was found in both treatment groups, even at week 2 but especially after 6 weeks of treatment. Improvement was not only seen in dimensions measuring depression or mental health but also in other dimensions.

An open, randomized comparison of artemether-benflumetol (CGP 56 697; Novartis) with artesunate-mefloquine was conducted in 617 patients with acute uncomplicated multidrug-resistant falciparum malaria on the western border of Thailand. Both treatments rapidly and reliably cleared fever and parasitemia, and there was no significant difference in the initial therapeutic response parameters. Parasite genotyping was used to distinguish recrudescences from new infections. The 63-day cure rate for artesunate-mefloquine (94%) was significantly higher than the cure rate for artemether-benflumetol (81%) (P < 0.001). Both regimens were well tolerated. Nausea, vomiting, dizziness, sleep disorders, and other neurological side effects were between two and four times more common in the artesunate-mefloquine group than in the artemether-benflumetol group (P < 0.001). Artemether-benflumetol is effective and very well tolerated in the treatment of multidrug-resistant falciparum malaria. A higher dose than that used in the present study may improve efficacy.

The purpose of this atlas is to present a review of the literature showing the advantages of SPECT brain perfusion imaging (BPI) in mild or moderate traumatic brain injury (TBI) over other morphologic imaging modalities such as x-ray CT or MRI. The authors also present the technical recommendations for SPECT brain perfusion currently practiced at their center. For the radiopharmaceutical of choice, a comparison between early and delayed images using Tc-99m HMPAO and Tc-99m ECD showed that Tc-99m HMPAO is more stable in the brain with no washout over time. Therefore, the authors feel that Tc-99m HMPAO is preferable to Tc-99m ECD. Recommendations regarding standardizing intravenous injection, the acquisition, processing parameters, and interpretation of scans using a ten grade color scale, and use of the cerebellum as the reference organ are presented. SPECT images of 228 patients (age range, 11 to 88; mean, 40.8 years) with mild or moderate TBI and no significant medical history that interfered with the results of the SPECT BP were reviewed. The etiology of the trauma was in the following order of frequency: motor vehicle accidents (45%) followed by blow to the head (36%) and a fall (19%). Frequency of the symptoms was headache (60.9%), memory problems (27.6%), dizziness (26.7%), and sleep disorders (8.7%). Comparison between patients imaged early (<3 months) versus those imaged delayed (>3 months) from the time of the accident, showed that early imaging detected more lesions (4.2 abnormal lesions per study compared to 2.7 in those imaged more than 3 months after the accident). Of 41 patients who had mild traumatic injury without loss of consciousness and had normal CT, 28 studies were abnormal. Focal areas of hypoperfusion were seen in 77% (176 patients, 612 lesions) of the group of 228 patients. The sites of abnormalities were in the following order: basal ganglia and thalami, 55.2%, frontal lobes, 23.8%, temporal lobes, 13%, parietal, 3.7%, insular and occipital lobes together, 4.6%.

The authors prospectively assessed symptoms induced by the interruption of antidepressants in 16 patients (11 women and 5 men), aged from 33 to 85 years (mean = 52.4 +/- 16.4), treated with antidepressants since at least two weeks. All patients were free of alcohol abuse or dependence disorder and of other dependence to psychoactive substances. None of them presented medical illness. Diagnosis were made by separate evaluations by two authors and confirmed with a semistructered assessment instrument: the Schedule for Affective Disorders and Schizophrenia (Lifetime Version). All patients were submitted to a brutal discontinuation of their antidepressant agent. Patients were assessed twice, before the interruption of the antidepressant, and 72 hours later. Effects of antidepressant interruption were assessed by several means. Modification of anxiety and depression were evaluated using the Montgomery Asberg Depression Rating Scale (MADRS) and the Hamilton Anxiety Scale. Symptoms of withdrawal were assessed with Cassano and al.'s scale SESSH including an evaluation of anxiety, agitation, irritability, anergy, difficulty on concentrating, depersonalization, sleep and appetite disorders, muscle pains, nausea, tremor, sweating, altered taste, hyperosmia, paresthesias, photophobia, motor incoordination, dizziness, hyperacousia pain, delirium. Fourteen of the 16 patients (87.5%) presented modifications of their somatic or psychic state 3 days after the interruption of the antidepressant treatment. Most frequent symptoms were: increase in anxiety (31%), increase in irritability (25%), sleep disorders (19%), decrease of anergia and fatigue (19%). Mean scores of anxiety and depression were not significantly modified by the withdrawal. Following TCAs interruption (7 patients) most frequent symptoms were sleep disorders; increase in anxiety, nausea. Among patients withdrawn from SSRIs (6 patients), most frequent symptoms were increase in anxiety, increase in irritability, headache. Patients also presented a decrease of nausea, and of anorexia.
