The investigation of personality traits of migraineurs with the Minnesota Multiphasic Personality Inventory (MMPI) is an important line of research, but so far has led to diverse conclusions. In this study, the MMPI (Chinese edition) responses of 50 Chinese subjects (10 men, 40 women) with migraine (4 migraine with aura, 46 without aura), during frequent headache attacks were compared with 30 nonheadache healthy control subjects (6 men, 24 women). Statistical analysis was made between the two groups. The results revealed that subjects in the migraine group had significantly higher scores on subtests of neurotic, (hypochondriasis, depression, hysteria, and psychasthenia), schizophrenia, and social introversion (P < 0.05 to 0.001). Utilizing the American T-score, we found the migraine group's MMPI profile was a typical 1.2.3.7 model. These results suggest migraineurs with frequent headache attacks have multiphasic personality abnormalities and partial cerebral function disturbances.

The use of psychotropic drugs has been associated with the syndrome of inappropriate antidiuretic hormone secretion (SIADH) in a number of case reports. SIADH is characterised by the sustained release of antidiuretic hormone (ADH) from the posterior pituitary. The patients have a reduced ability to excrete diluted urine, ingested fluid is retained, and the extracellular fluid expands and becomes hypo-osmolar. The cardinal signs are hyponatraemia, serum hypoosmolality and a less than maximally diluted urine. Common symptoms include weakness, lethargy, headache, anorexia and weight gain. These symptoms may be followed by confusion, convulsions, coma and death. The early symptoms are vague and nonspecific, and they may even mimic the symptoms of the psychiatric disorder itself. For antidepressants, the risk of SIADH seems to be highest during the first weeks of treatment. For antipsychotics, the risk seems to be more spread out in time. The causative role of the drug may sometimes be difficult to estimate, as even drug-free psychiatric patients, mostly those with schizophrenia, develop SIADH on the basis of psychogenic polydipsia. Smoking is another factor associated with the development of SIADH, and the risk may also increase with age. The acute treatment of SIADH induced by a psychotropic drug includes discontinuation of the drug as well as restriction of fluid intake. In cases with significant clinical symptoms, infusion of sodium chloride is recommended. After the acute management, it is useful to evaluate the causative role of the drug by performing a water loading test and/or drug rechallenge. If continued treatment with an antidepressant or antipsychotic is indicated, a drug with a different pharmacological profile should be chosen, and the serum sodium levels should be monitored closely. If treatment with the drug that caused SIADH must be continued, concomitant treatment with demeclocycline may reduce the tendency of hyponatraemia.

A double-blind, randomized study of parallel group design comparing remoxipride and thioridazine (dose range 150-600 mg/day of either drug) was undertaken at 11 Australian centres. A total of 144 patients (remoxipride = 73, thioridazine = 71) with DSM-III-R schizophrenia or schizophreniform disorder commenced the study, and 89 patients (remoxipride = 45, thioridazine = 44) completed the 6 weeks of the trial. The mean daily doses at last rating were 404 mg (remoxipride) and 378 mg (thioridazine). Initial Brief Psychiatric Rating Scale scores decreased by a mean 8.7 points in both remoxipride and thioridazine groups. Equivalent treatment responses were also confirmed by Clinical Global Impression. During the study, sedatives or hypnotics were needed by 68% of the remoxipride patients and 51% of the thioridazine patients. Thioridazine was associated with more postural hypotension, drowsiness, increased sleep, headache, dizziness on rising, dry mouth, sexual dysfunction and weight gain, while remoxipride patients reported more insomnia. There were no differences between remoxipride and thioridazine on dystonia, hypokinesia, dyskinesia, rigidity and akathisia. The results indicate that remoxipride has similar antipsychotic efficacy to thioridazine but causes fewer side effects.

There is evidence that the psychiatric importance of hypochondriacal or cenestopathic symptoms in schizophrenia is prone to be neglected, in so far as these symptoms are expressed through the discourse of somatic medicine. Psychopathological studies of these symptoms are few as compared to studies of other schizophrenic symptoms such as delusion or verbal acoustic hallucination. However, it could be said that such study is indispensable in developing both an understanding of schizophrenics and therapeutic strategies for the treatment of them, in so far as hypochondriaco-cenestopathic symptoms directly indicate a pathology of body-consciousness in schizophrenia. Motivated by these practical as well as theoretical demands, the author presents first of all statistical characteristics of hypochondriaco-cenestopathic symptoms based on a longitudinal study of 183 schizophrenic patients, who were observed for at least 5 years. All the patients satisfied the DSM-III-R criteria for schizophrenia. Taking into consideration these statistical characteristics, as well as certain detailed representative cases, the author proposes a new psychopathological perspective of the hypochondriaco-cenestopathic symptoms in schizophrenia. The essential result of this statistical investigation is summarized as follows. 81 schizophrenic patients exhibited the hypochondriaco-cenestopathic symptoms, accounting for 44.3% of the sample. If we exclude the cases which presented physical experience of being influenced (physikalische Beeinflussungserlebnis), appearance frequency of hypochondriaco-cenestopathic symptoms accounted for 27.9% of the sample. Among the manifestations of these symptoms, uncharacteristic somatic complaint was the most frequent. Here, the most common was pain of body (especially headaches). The second most common was complaint of easy fatigability. Concerning the appearance pattern of the symptom, we found no significant difference between the acute and chronic types, nor between the early and tardive types, while the complex type was significantly more frequent in comparison with the simple type. Among the other symptoms that co-occurred with the hypochondriaco-cenestopathic symptom, the most common was acoustic hallucination, whose frequency was highly statistically significant when compared to the non hypochondriaco-cenestopathic group. Regarding the relationship of the hypochondriaco-cenestopathic symptom with the subtypes of schizophrenia, the proportion of the paranoid type was significantly high in the non hypochondriaco-cenestopathic group.

The association between major depressive disorder (MDD) and self-reported histories of specific physical illnesses was investigated in 320 controls and 1968 first-degree relatives and 254 spouses of probands in the NIMH Collaborative Depression study. The Schedule for Affective Disorders and Schizophrenia-Lifetime Version was used to assign Research Diagnostic Criteria (RDC) diagnoses and a structured self-report instrument was used to assess lifetime medical history. Lifetime MDD was diagnosed in 914 subjects, 402 of whom had been hospitalized or received somatic treatment ('treated' MDD). Strong associations were observed between MDD (either treated or untreated) and both frequent/severe headaches and migraine headaches. There was a marked gender effect such that the relative odds for a woman with treated MDD to report migraine were over 5:1. Other associations were found between MDD and skin infections, respiratory illness, ulcer, hypotension, and diabetes. This is the largest non-patient sample using standardized assessment of mental disorders by direct interview in which associations between specific physical illnesses and MDD have been demonstrated. Implications for clinical practice and neurobiological research in depression are discussed.

During a 24-month period, 205 consecutive new referrals to Muhimbili psychiatric unit were studied. Their socio-demographic characteristics, sources of referral, types of treatment received before referral and the nature of their clinical problems were identified. Their neuropsychiatric disorders were classified according to ICD-10. The ratio of males to females was found to be 1.6:1. The average age was 29.3 years. 23.4% of adult patients were unemployed, two fifths of all patients were single and 70% of all subjects had less than eight years of formal education. Whereas 42.9% of all referrals were from other departments of Muhimbili hospital, the remaining were largely from parastatal dispensaries, district and regional hospitals within Dar es Salaam city. At least a fifth of all patients had consulted traditional healers prior to referral and antimalarials had been given inappropriately to 34 patients with mental problems. Mental disorders consisted of functional psychosis, 36.6% of which three quarters were schizophrenia, neurosis (19.5%), seizures (16.6%), substance abuse (8.8%), organic mental disorders (5.3%), headache (4.9%), sexual dysfunction (2.9%). The rest had conduct disorders and pseudocyesis. Seventeen percent of all cases had concomitant physical disorders. Most patients had delayed to seek medical help.

The social and clinical characteristics of one hundred and thirty-one women who attended the psychiatric outpatient clinic for the first time at the Department of Psychiatry, University of Ghana Medical School, within five years (1988-1992) were studied. The data suggested that the peak age of depressed women at consultation was between twenty and forty; and that a significant proportion of them were in the married group. Moreover the majority have no or very little education and thus little opportunity for gainful employment hence the majority were self employed. This finding is markedly different from the findings in the Western Countries, where the depressed women were much older, between thirty-five and fifty-four years; single and were gainfully employed. The average number of children per woman were between five and eight and the women had no adequate financial support from their husbands. These social characteristics reflected in the life-style and the kind of social stresses imposed upon these women in coping with life. These stresses showed in the clinical symptoms they represented, which were mainly somatisation disorder and somatic symptoms, with headaches and insomnia being the most prominent. However, psychological symptoms such as morbid thoughts were found to be few at this first consultation. It was highlighted that the social stresses might possibly be the causes of the clinical presentation of the depressed Ghanaian women. It was suggested that the specificity of headaches as a symptom of other psychiatric disorders other than depressive illness, for example schizophrenia and other endogenous psychiatric disorder among Ghanaian women require further research.

The results of an open tolerability and exploratory efficacy study of bretazenil, a partial benzodiazepine-receptor agonist in hospitalized schizophrenic patients with an acute psychotic episode (DSM-III-R criteria), are presented. The duration of the study was 6 weeks, with a mandatory titration (ascending doses of 3-18 mg/day) period of 14 days. The assessment criteria for tolerability were the frequency of adverse events (including EPS), vital signs and laboratory tests. The efficacy criteria, which were only descriptively analysed, were: (a) Clinical Global Impression (CGI, percentage of "very much" and "much" improvement); and (b) change in BPRS total score (e.g. percentage of patients showing > or = 40% decrease of BPRS score at the end of the treatment). Sixty-six patients (aged 21-62 years) with acute episodes of schizophrenia of moderate to marked severity (mean BPRS score = 46.3, range 26-76) were included in the study. Of these 66 patients (68%) were reportedly non-responders (n = 10) or partial responders (n = 35) to previous neuroleptic therapy. Twenty patients (30%) terminated the trial prematurely due to therapeutic failure (no improvement or worsening after 2 weeks of treatment), 17% of patients dropped out due to other reasons (transfer to other hospitals, withdrawal of consent, intercurrent diseases) and 4.5% of patients stopped the treatment due to adverse reactions. Four patients (6%) showed early complete remission and refused to be further treated. The analysis of efficacy (intention-to-treat) revealed a sustained decrease of BPRS scores with 49% of patients showing > or = 40% BPRS score change by the end of the treatment. Forty-four per cent of patients improved "very much" or "much". Eleven patients (17%) were full responders (BPRS score decrease 75-100%) and 21 patients (32%) showed at least 40% reduction of BPRS score. The reduction of BPRS scores in completers only was 60%. All BPRS factor scores decreased in parallel and, particularly, no preferential decrease of anxiety/depression subscores was found. The analysis of tolerability showed that 59% of patients presented no complaints at all. The most frequent treatment-related adverse reactions in the remaining patients were: sedation (n = 14), dizziness (n = 4) and headache (n = 3). The results of this study suggest moderate antipsychotic efficacy of bretazenil in schizophrenic patients. They encourage further investigations of partial benzodiazepine-receptor agonists in this indication, particularly because of the excellent tolerability and lack of extrapyramidal side-effects.

Following the conduct of a 28-day inpatient bioequivalence study of clozapine in schizophrenia patients, withdrawal effects after abrupt discontinuation from clozapine were assessed. Thirty patients who met DSM-III-R criteria for schizophrenia, residual type, or schizophrenia in remission were enrolled in the study. Patients were evaluated for symptoms of withdrawal effects for 7 days after clozapine 200 mg/day was abruptly withdrawn. Of 28 patients who completed the study, 11 had no withdrawal symptoms; 12 had mild withdrawal adverse events of agitation, headache, or nausea; four patients experienced moderate withdrawal adverse events of nausea, vomiting, or diarrhea; and one patient experienced a rapid-onset psychotic episode requiring hospitalization. Cholinergic rebound is a likely explanation for the mild to moderate withdrawal symptoms and is easily treated with an anticholinergic agent. Mesolimbic supersensitivity, as well as specific properties of clozapine, are discussed as likely causes for rapidonset psychosis. Our findings are consistent with previous reports of withdrawal reactions associated with clozapine, further reminding clinicians to monitor patients closely following abrupt discontinuation of clozapine.

In contrast to the well known chlorpromazine-induced cholestatic hepatitis, we report the case of a schizophrenic patient who presents a cytolytic hepatitis, without any prior hepatic disease. Mr G. was first hospitalized for depressive symptomatology. A pseudo-nevrotic schizophrenia was diagnosed. Pretherapeutic clinical and biological data were normal. A treatment with chlorpromazine 400 mg/day was given. At day 8, the patient was still anxious and began to be agitated. An increase to 500 mg/day of chlorpromazine posology and an addition of haloperidol 200 mg/day was implemented. At day 10, the following clinical symptoms appeared: 38.6 degrees C fever; headache; myalgia; epigastralgia and hypocondrium pain. Biological hepatitis disturbances (ALAT, 984 U/L; ASAT, 414 U/L) and hypereosinophilia with normal white cell count were found. Clinical and biological investigations were normal. Blood-culture, A, B, C hepatitis, HIV and CMV serologies were negative. Neuroleptic treatment was discontinued. Evolution to normality of the disturbances and biological data suggested a cytolytic hepatitis. Mr G... remained treated with flupentixol without side-effects. Phenothiazine-induced cholestatis is frequent, mild, and recovers spontaneously. The biological mechanism is supposed to be immunologic. Prevalence of biological hepatic disturbances is 10 to 20% with chlorpromazine in long-term treatment. More often, symptomatology is the same; jaundice, pruritus, abdominal pain, fever. Although pharmacological data suggest for a cytotoxic activity of phenothiazines, cytolytic hepatitis is poorly described. Maximum range of transaminase blood level reported in previous studies is about 400 U/l. This level is not clearly correlated with hepatic cell lysis. Few cases of hepatic necrosis have been reported. In all cases, preexistent hepatic injuries were observed. Chlorpromazine-induced cytolytic hepatitis is uncommon and cholestatic hepatitis mild. Biological hepatic parameters investigations remain necessary during neuroleptic treatment.
