TL;DR: Findings from the epidemiological monitoring project are presented, based on a preliminary examination of data collected in 15 centres on parasuicides aged 15 years and over treated in health facilities in defined catchment areas during the year 1989, and it is argued that the differences between centres are valid and should be addressed in further research.
Abstract: The WHO/EURO multicentre study on parasuicide is a new, coordinated, multinational, European study that covers two broad areas of research: monitoring trends in the epidemiology of parasuicide (epidemiological monitoring study); and follow-up investigations of parasuicide populations, with a view to identifying the social and personal characteristics predictive of future suicidal behaviour (repetition prediction project). This article provides background information on the development and organization of the multicentre study, and presents selected findings from the epidemiological monitoring project, based on a preliminary examination of data collected in 15 centres on parasuicides aged 15 years and over treated in health facilities in defined catchment areas during the year 1989. The overall parasuicide incidence varied considerably across the centres, from a high (event) rate of 414 per 100,000 males in Helsinki to a low of 61 among males in Leiden. The highest female event rate was 595 in Pontoise, and the lowest 95 in Guipuzcoa. The mean event rate across all centres was 167 among males and 222 among females. Parasuicide incidence tended to be elevated among 15- to 34-year-olds, with lowest rates among those aged 55 years and over. With one exception (Helsinki), the female parasuicide rate was higher than the male rate, the F:M ratio ranging from 0.71:1 to 2.15:1, with a median of 1.5:1 (events). Short-term repetition rates (as measured by the event:person ratio) differed between centres, from 1.03 to 1.30 (median = 1.12) among males, and from 1.07 to 1.26 (median = 1.13) among females. Although we warn against generalizing from our findings to make statements about differences in parasuicide between countries, we argue that the differences between centres are valid and should be addressed in further research.

TL;DR: The results indicate that educational programs that can have pronounced effects on the health care system have to be repeated approximately every 2 years if long‐term effects are to be expected.
Abstract: In 1983-1984 the Swedish Committee for the Prevention and Treatment of Depression offered an educational program on diagnosis and treatment of depressive disorders to all general practitioners on the island of Gotland. The program has been carefully evaluated; 1982 was used as the baseline and the main evaluation was carried out in 1985. After the educational programs, the frequency of sick leave for depressive disorders decreased, the frequency of inpatient care for depressive disorders decreased to 30% of that at the baseline; the prescription of antidepressants increased, but prescription of major tranquilizers, sedatives and hypnotics decreased. The frequency of suicide on the island decreased significantly. This study describes the long-term effects. In 1988, 3 years after the project ended, the inpatient care for depressive disorders increased, the suicidal rate returned almost to baseline values and the prescription of antidepressants stabilized. Thus, the effects were strictly related in time to the educational programs, indicating that the effects were real and not only a coincidence with local trends on Gotland. Furthermore, the results indicate that educational programs that can have pronounced effects on the health care system have to be repeated approximately every 2 years if long-term effects are to be expected.

TL;DR: In patients with alcohol‐related severe hepatocellular damage, the oxidative P 450 catalyzed formation of the Me‐DTC and probably also of its sulfoxide and sulphone metabolites is impaired, and thus inactivation of ALDH activity in the liver appears to be delayed or even completely absent.
Abstract: After ingestion, disulfiram (DSF) is rapidly converted, probably in the stomach, to its bis (diethyldithiocarbamato) copper complex. Consequently, absorption and distribution via the gastrointestinal mucosa into the blood might involve both the parent drug and its copper complex. In the blood, both compounds are rapidly degraded to form diethyldithiocarbamic acid (DDC), which is unstable and is further degraded to form diethylamine and carbon disulphide. DDC is also a substrate of phase II metabolism, which involves formation of diethyldithiomethylcarbamate (Me-DDC) and the glucuronic acid of DDC. Me-DDC also undergoes oxidative biotransformation to diethylthiomethylcarbamate (Me-DTC), which is further oxidized to its corresponding sulphoxide and sulphone metabolites. Me-DTC may to act as a suicide inhibitor with a preference for the mitochondrial low Km isozyme of aldehyde dehydrogenases (ALDH 1), whereas the two S-oxidized metabolites, especially the sulfone metabolite, are more potent inhibitors not only of ALDH 1, but also of the cytosolic high Km isozyme of ALDH (ALDH 2). The inhibitory reaction between the enzyme and each of the three metabolites is characterized by a covalent adduct formation, probably with the cysteine residue at the active site of the enzymes. The adduct formed is nonreducible at a physiological concentration of glutathione, and inactivation in the presence of this endogenous tripeptide was increased by action in vitro of the sulphoxide and sulphone metabolites. Those findings are all in concordance with the in vivo observations made on DSF. In human volunteers treated with increasing doses of DSF and challenged with ethanol between each of the dosage periods, the mean plasma concentrations of Me-DTC at steady state were proportional to the DSF doses given. There was also a close relationship between increased oxidative metabolic formation of Me-DTC, high oxidative formation of acetaldehyde, and the full complements of a valid disulfiram ethanol reaction (DER). Consequently, Me-DTC in plasma may not only serve as a marker of the oxidative metabolic function of the liver, but also of the therapeutic effectiveness of the treatment in subjects at steady state. Obviously, there is a need for individual dose-titration regimens. In patients with alcohol-related severe hepatocellular damage, the oxidative P 450 catalyzed formation of the Me-DTC and probably also of its sulfoxide and sulphone metabolites is impaired, and thus inactivation of ALDH activity in the liver appears to be delayed or even completely absent. The consequence for the patient may be an insufficient DER.(ABSTRACT TRUNCATED AT 400 WORDS)

TL;DR: R risperidone is comparable to haloperidol as an antipsychotic, but that it has a safer EPS profile, according to the laboratory, endocrinological and cardiovascular safety parameters.
Abstract: Forty-four chronic schizophrenic inpatients participated in this multicentre 12-week parallel-group double-blind trial. After a run-in period of 2 weeks and a single-blind placebo wash-out of 1 week, they were randomly assigned to treatment with either the serotonin2 and dopamine-D2 antagonist risperidone or haloperidol. Two patients were excluded from the efficacy analysis. Five patients dropped out in the haloperidol group and 1 in the risperidone group. At the end of the trial, the mean daily dose was 12 mg for risperidone and 10 mg for haloperidol. The risperidone group showed greater improvement on the Positive and Negative Syndrome Scale for Schizophrenia, the Schedule for Affective Disorders and Schizophrenia-change version, and the Nurses' Observation Scale for Inpatient Evaluation. The improvement of negative symptoms was more pronounced in the risperidone group until week 8 of double-blind treatment. The consumption of antiparkinsonian medication was 10 times lower with risperidone. Both drugs were well tolerated and the laboratory, endocrinological and cardiovascular safety parameters were comparable. This study suggests that risperidone is comparable to haloperidol as an antipsychotic, but that it has a safer EPS profile.

TL;DR: Results of ratings on the Gottfries‐Bråne‐Steen dementia rating scale indicated that both cognitive and emotional functioning improved significantly more in the citalopram‐ treated subgroup of patients with dementia than in the placebo‐treated subgroup.
Abstract: A total of 149 patients in 7 centers in Denmark, Norway and Sweden entered a 6-week double-blind trial intended to assess the antidepressant effect and safety of citalopram vs placebo in depressed elderly patients (65 years of age or older) who might also suffer from somatic disorders and/or senile dementia. Results of ratings on the Hamilton Rating Scale for Depression, the Montgomery-Asberg Depression Rating Scale and the Clinical Global Impression Scale provided consistent evidence that the citalopram-treated patients improved more than the placebo-treated patients. Results of ratings on the Gottfries-Brane-Steen dementia rating scale indicated that both cognitive and emotional functioning improved significantly more in the citalopram-treated subgroup of patients with dementia than in the placebo-treated subgroup.

TL;DR: Demographic characteristics (gender, age, race, educational level) and diagnostic variables were strong predictors of type of substance abuse and the results demonstrate the importance of matching groups on demographic characteristics when exploring diagnostic differences in preference to abuse specific types of substances.
Abstract: The relationship between history of specific types of substance abuse (alcohol, stimulants, cannabis, hallucinogens, narcotics) and demographic and diagnostic variables was evaluated in a large (n = 263) sample of schizophrenic, schizoaffective, major depression and bipolar disorder patients. Prevalence rates were also compared with rates observed in a previous study (1983-1986) conducted using the same methods. Demographic characteristics (gender, age, race, educational level) were strong predictors of type of substance abuse. Patients with a history of cocaine abuse had fewer prior hospitalizations, suggesting that less impaired psychiatric patients may be more prone to illicit substance abuse. Diagnoses were not related to most types of substance abuse, although there was a trend for bipolar patients to have a history of alcohol abuse. The results demonstrate the importance of matching groups on demographic characteristics when exploring diagnostic differences in preference to abuse specific types of substances.

TL;DR: In 1982‐1983 a random sample of 1486 people aged 65 years and above was generated from general practitioner lists; 1070 were interviewed in the community using the Geriatric Mental State and a Social History questionnaire, and the cohort was followed up by interview 3 years later.
Abstract: In 1982-1983 a random sample of 1486 people aged 65 years and above was generated from general practitioner lists; 1070 were interviewed in the community using the Geriatric Mental State and a Social History questionnaire. The cohort was followed up by interview 3 years later. At year 3 the diagnostic computer program AGECAT diagnosed 44 incident cases of depression. Information from the depressed group's initial and further interviews was compared with a control group (which excluded cases of affective or organic mental illness). Univariate analysis yielded three factors that were significantly associated with the development of depression 3 years later: a lack of satisfaction with life; feelings of loneliness; and smoking. Multivariate analysis confirmed their independent effects and revealed 2 further factors attaining significance: female gender and a trigger factor, bereavement of a close figure within 6 months of the third-year diagnosis. Some other factors traditionally associated with depression, such as poor housing, marital status and living alone, failed to attain significance as risk factors.

TL;DR: The results suggest that the consumption of cannabis by schizophrenic patients could attenuate negative symptoms, which would support the self‐medication hypothesis of cannabis abuse.
Abstract: A study was carried out on a group of 95 schizophrenic patients (DSM-III-R criteria) under the age of 35, 23 of whom were cannabis abusers in the past year. The objective of the study was to evaluate the effect of cannabis on positive and negative schizophrenic symptoms, evaluated using Andreasen's Scales for the Assessment of Positive and Negative Symptoms (SAPS and SANS). There were no statistically significant differences between the groups on the SAPS; the group of cannabis abusers had higher scores except for the delusions subscale. On the SANS nonabusers scored higher, with a significant difference on the alogia subscale. The results suggest that the consumption of cannabis by schizophrenic patients could attenuate negative symptoms, which would support the self-medication hypothesis of cannabis abuse.

TL;DR: The data show that the mortality of manic‐depressive and schizoaffective patients given long‐term lithium treatment does not differ significantly from that of the general population.
Abstract: Clinical research centers in Aarhus, Berlin, Hamilton and Vienna collected mortality data for 827 manic-depressive and schizoaffective patients given lithium treatment for more than 6 months. The average duration of the treatment was 81 months and the total time on lithium 5600 patient-years. For each patient, the mortality risk was calculated by entering the appropriate national life tables for the general population. The number of observed deaths was 44; the number of expected deaths was 49.7. The standardized mortality ratio, 0.89, did not differ significantly from 1.0. The mortality of manic-depressive patients is 2-3 times that of the general population. Our data show that the mortality of manic-depressive and schizoaffective patients given long-term lithium treatment does not differ significantly from that of the general population.

TL;DR: The behavioral, biochemical and cardiovascular effects of intravenous yohimbine and clonidine were determined and are consistent with a large body of preclinical and human data relating increased noradrenergic neuronal function to human anxiety and fear states.
Abstract: In order to evaluate possible abnormal noradrenergic neuronal functional regulation in patients with panic disorder, the behavioral, biochemical and cardiovascular effects of intravenous yohimbine (0.4 mg/kg) and clonidine (2 micrograms/kg) were determined in 15 healthy subjects and 38 patients with panic disorder. A subgroup of 24 panic disorder patients were observed to experience yohimbine-induced panic attacks and had larger yohimbine-induced increases in plasma 3-methoxy-4-hydroxyphenylglycol (MHPG) than healthy subjects and other panic disorder patients. A blunted growth hormone response to clonidine and a significant clonidine-induced decrease in plasma MHPG was also observed in this subgroup of panic disorder patients. These data replicate and extend previous investigations, which are consistent with a large body of preclinical and human data relating increased noradrenergic neuronal function to human anxiety and fear states.

TL;DR: It is concluded that low doses of clomipramine effectively reduce premenstrual irritability and dysphoria with a response rate close to 100%.
Abstract: Forty nondepressed women displaying severe premenstrual irritability and/or dysphoria and fulfilling the DSM-III-R criteria of late luteal phase dysphoric disorder were treated daily for 3 menstrual cycles with either the potent serotonin reuptake inhibitor clomipramine (25-75 mg; flexible dosage) (n = 20) or placebo (n = 20). In both treatment groups premenstrual irritability and dysphoria (as rated daily by the patients using a visual analogue scale) were significantly reduced as compared with the rating during 2 pretreatment reference cycles; however, in the placebo group this reduction was only about 40% whereas, in the clomipramine group, the symptom decrease was greater than 80%. At all 3 treatment cycles, patients on clomipramine displayed significantly lower symptom rating than controls. Also with respect to the rating of global improvement, the results obtained with clomipramine were considerably and significantly better than those obtained with placebo. It is concluded that low doses of clomipramine effectively reduce premenstrual irritability and dysphoria with a response rate close to 100%. The possible role of serotonin in the pathophysiology of the premenstrual syndrome is discussed.
TL;DR: It is postulate that other factors (such as intellect, past experience, personality etc.) must be involved in modulating the expression of insight in patients suffering from schizophrenia or depression.
Abstract: Difficulties surrounding the meaning of insight in psychiatry have led to neglect of its assessment in clinical practice. A study is described in which an insight scale was constructed and tested in a sample of 43 patients suffering from schizophrenia or depression. The results showed that the insight instrument was able to provide a qualitative and quantitative assessment of insight. Qualitative features brought out by the scale included patients' perception of changes within themselves and within their environment, their recognition of being ill and their acknowledgment of needing help. Quantitative measurements showed that there was a significant improvement in the level of insight over the period of hospital admission. In addition, scores obtained on the insight scale were inversely correlated with the severity of the patients' disorder, though these correlations occurred at different times in relation to the different disorders. We thus postulate that other factors (such as intellect, past experience, personality etc.) must be involved in modulating the expression of insight. Although the insight instrument needs refining, we suggest that it may be a useful tool in the further exploration of insight in clinical practice.
TL;DR: The findings extend earlier work showing higher HC in vascular patients from general medical populations, and also suggest a possible metabolic factor in certain dementias associated with late‐life depression.
Abstract: Depression among elderly people with reversible cognitive loss often manifests with concomitant vascular disease and can also precede the development of nonvascular degenerative dementia. Little is known about etiological factors for reversible or irreversible dementias in older depressed people. The amino acid homocysteine (HC), which is both a vascular disease risk factor and a precursor of the excitotoxic amino acids cysteine and homocysteic acid, could play a role in the pathophysiology of such individuals. Twenty-seven depressed elderly acute inpatients by DSM-III-R criteria had significantly higher plasma homocysteine levels and lower cognitive screening test scores than did 15 depressed young adult inpatients. HC was highest in the older patients who had concomitant vascular diseases (n= 14). HC was lowest in the older depressives who had neither vascular illnesses nor dementia (n= 8), comparable to the young adult depressives. Higher HC correlated significantly with poorer cognition only in the nonvascular geriatric patients (rs= -0.53). The findings extend earlier work showing higher HC in vascular patients from general medical populations, and also suggest a possible metabolic factor in certain dementias associated with late-life depression.
TL;DR: It is concluded that carbamazepine is as effective as lithium in the prophylaxis of bipolar affective disorder; changeover from lithium to carbamazepsine should be done slowly.
Abstract: A 12-month double-blind trial of carbamazepine vs lithium, given as sole treatment for the prophylaxis of bipolar affective disorder, was carried out in 31 patients. All were previously stable on lithium; 15 were switched over to carbamazepine and 16 remained on lithium. Although the overall relapse rate was similar in the 2 groups (6 on carbamazepine, 8 on lithium), nearly all the relapses in carbamazepine occurred in the first month, probably precipitated by lithium withdrawal. Two patients on carbamazepine developed a rash and were withdrawn. More side effects were noted during the early stages on carbamazepine. Patients on lithium tended to gain weight (+4 kg) compared with carbamazepine (-3.1 kg). It is concluded that carbamazepine is as effective as lithium in the prophylaxis of bipolar affective disorder; changeover from lithium to carbamazepine should be done slowly.
TL;DR: In this community study the consequences associated with sexual abuse within the family appear to be widespread and not very specific, and show as additional comorbidity rather than as increased severity within a disorder.
Abstract: This study reports results from follow-up interviews with 301 women aged 18-44 years who were first identified 2 years earlier in a cross-sectional study of 1498 adults in the general population of the city of Christchurch, New Zealand. The prevalence of intrafamilial sexual abuse was 13%. This incestuous sexual abuse in childhood was associated with an increase in many adult mental symptoms, particularly symptoms of depression, bulimia and generalized anxiety. In this community study the consequences associated with sexual abuse within the family appear to be widespread and not very specific, and show as additional comorbidity rather than as increased severity within a disorder. These results do not support the strong direct causal effects postulated in some theories derived from clinical studies.
TL;DR: Regional abnormalities of in vivo31P NMR spectra in the brains of chronic schizophrenic patients may represent different patterns of dysfunction of membrane phospholipid bilayers and high‐energy phosphate metabolism in the specific cerebral regions.
Abstract: Phosphorus-31 chemical shift imaging showed regional abnormalities of in vivo 31P NMR spectra in the brains of chronic schizophrenic patients. In the left temporal region, the level of % phosphodiesters (PDE) was increased and the level of % gamma alpha beta-ATP (obtained by summation of gamma-ATP, alpha-ATP, and beta-ATP) was decreased. In the basal ganglia, the levels of % PDE were decreased and the level of % phosphomonoesters was increased. The levels of % gamma alpha beta-ATP were increased in the right basal ganglia. The level of % phosphocreatine was decreased in the frontoparietal region. These findings may represent different patterns of dysfunction of membrane phospholipid bilayers and high-energy phosphate metabolism in the specific cerebral regions.
TL;DR: The burden of care experienced by family members of 90 patients with major affective disorder was evaluated and the burden was significantly more among families of bipolar patients than those of major depression.
Abstract: The burden of care experienced by family members of 90 patients with major affective disorder was evaluated. The extent of burden in these families was considerable. The burden was significantly more among families of bipolar patients than those of major depression. Prolonged illness and high levels of dysfunction among patients correlated consistently with severity of burden. Severity of illness, higher age of the patient and number of episodes of the illness also influenced the extent of burden. Variables such as gender of the patient, religion, education, occupation, family type and size and the locus of control of both patients and relatives did not influence the extent of burden significantly. These results have substantial implications for the planning of intervention strategies.
TL;DR: This article describes a comparison of Composite International Diagnostic Interview (CIDI) diagnostic results and results based on clinicians’ observation of CIDI assessments, consistent with the results from a similar comparison between the C IDI and checklist results for ICD‐10 diagnoses.
Abstract: This article describes a comparison of Composite International Diagnostic Interview (CIDI) diagnostic results and results based on clinicians' observation of CIDI assessments. Psychiatrists scored a DSM-III-R criteria checklist either while observing or after administering 20 CIDI interviews. Overall diagnostic concordance between the checklist and CIDI diagnoses was found to be good (kappa = 0.78). Good diagnostic agreement was also found for 3 groups of DSM-III-R disorders: depressive disorders (kappa = 0.84), psychoactive substance use disorders (kappa = 0.83) and anxiety phobic disorders (kappa = 0.76). These results are consistent with the results from a similar comparison between the CIDI and checklist results for ICD-10 diagnoses.
TL;DR: A normal isozyme pattern seems to be a prerequisite for the development of alcoholism, which supports the principle of disulfiram treatment and Measurements of plasma Me‐DTC or the reduction of leucocyte ALDH 1 activity may be valuable markers for the proper dose titration and the rational use of this drug.
Abstract: Disulfiram (Antabuse) is one of several aldehyde dehydrogenase (ALDH) inhibitors that raise the plasma level of acetaldehyde following ethanol ingestion. The usually pleasant reaction to ethanol is thereby changed to an unpleasant one, owing to a number of bodily reactions to acetaldehyde. Populations showing genetic polymorphism with a lack of some isozymes of ALDH have exhibited an intolerance to ethanol similar to that seen with disulfiram. A normal isozyme pattern seems to be a prerequisite for the development of alcoholism, which supports the principle of disulfiram treatment. Disulfiram is an irreversible ALDH inhibitor when administered in vivo. Diethylthiomethylcarbamate (Me-DTC) is formed from disulfiram in three metabolic steps. This compound and two further oxidized metabolites appear to be active metabolites of disulfiram. Measurements of plasma Me-DTC or the reduction of leucocyte ALDH 1 activity may be valuable markers for the proper dose titration of disulfiram and the rational use of this drug. Some toxicological points are discussed.
TL;DR: There was no relationship between D2/Taq 1 genotype and concentrations of these monoamine metabolites in this group, which exhibits lower CSF HVA and 5‐HIAA as compared to controls, and this lack of relationship was replicated in 24 Caucasian alcoholics in the United States.
Abstract: If a genetic association between the D2 dopamine receptor genotype and alcoholism is mediated by altered dopamine function, then a stronger association might be found in alcoholics who are deviant in indices of dopamine function and by comparing alcoholics to nonalcoholics matched for ethnic origin. Therefore, we evaluated the D2/TaqI polymorphism in 29 impulsive violent alcoholic Finns, 17 nonimpulsive violent alcoholic Finns and 36 Finnish controls free of mental disorders, alcoholism and substance abuse. In 37 of the alcoholics, we measured cerebrospinal fluid (CSF) homovanillic acid (HVA), 5-hydroxyindoleacetic acid (5-HIAA) and 3-methoxy-4-hydroxyphenylglycol. There was no relationship between D2/Taq 1 genotype and concentrations of these monoamine metabolites in this group, which exhibits lower CSF HVA and 5-HIAA as compared to controls. There was also no genotypic difference between Finnish alcoholics and nonalcoholic controls. The lack of relationship between D2/Taq1 genotype and HVA concentration was replicated in 24 Caucasian alcoholics in the United States.
TL;DR: It is argued that the general neurotic syndrome may represent a personality diathesis that makes the individual more vulnerable to both anxiety and depressive symptoms.
Abstract: The validity of the general neurotic syndrome, a combination of anxiety, depression and dependent personality disorder, was examined in a 2-year study of outpatients with dysthymic, panic and generalized anxiety disorder diagnosed using a structured interview schedule. The general neurotic syndrome, found in a third of the patients, was associated with greater mental disorder and a significantly worse outcome than patients without the syndrome. It did not, however, predict response to treatment. Further analysis revealed that the general neurotic syndrome was a better predictor of short- and long-term outcome than any other variable apart from initial psychopathology score. It is argued that the syndrome may represent a personality diathesis that makes the individual more vulnerable to both anxiety and depressive symptoms.
TL;DR: In a sample of 105 elderly subjects from 2 day centres and a psychiatric outpatient clinic in Singapore, the ECAQ was compared with Kahn's Mental Status Questionnaire and the sensitivity of the scales was found to be similar but the E CAQ had a higher specificity and positive predictive value, and lower overall miscalculation rate.
Abstract: Most questionnaires designed to assess cognitive impairment among elderly people are constructed in the West, where literacy is high. However, such questionnaires may not be applicable in developing countries because of cultural differences or low literacy. The Elderly Cognitive Assessment Questionnaire (ECAQ) is derived from items in the Mini-Mental State Examination and Geriatric Mental State Schedule. It is a satisfactory scale for quantitative assessment of cognitive impairment among elderly people living in developing countries. This 10-item questionnaire shows a sensitivity of 85.3%, specificity 91.5%, positive predictive value 82.8% and overall miscalculation rate 10.5%. In a sample of 105 elderly subjects from 2 day centres and a psychiatric outpatient clinic in Singapore, the ECAQ was compared with Kahn's Mental Status Questionnaire. The sensitivity of the scales was found to be similar but the ECAQ had a higher specificity and positive predictive value, and lower overall miscalculation rate.
TL;DR: The results indicated that Eysenck's neuroticism was the best predictor of negative interpersonal life events and symptoms added a negligible amount to the variance explained in the occurrence of life events.
Abstract: The element of chance and the role of the individual in causing negative life events was explored by examining the relationship between measures of personality, symptoms, and a number of demographic variables in a nonclinical population (n = 892). The results indicated that Eysenck's neuroticism was the best predictor of negative interpersonal life events. Symptoms added a negligible amount to the variance explained in the occurrence of life events. The well-established relationships between neuroticism and symptoms and life events and symptoms are discussed in the light of these findings.
TL;DR: The low rate of antidepressant prescription in patients committing suicide probably reflects insufficient diagnosis and treatment of depressive disorders, and it is urgent that diagnostic and pharmacotherapeutic routines be improved.
Abstract: The use of antidepressants has been low in Jamtland County for many years, while the suicide rate has been among the highest in Sweden. A continuous outpatient prescription recording system has been in operation in Jamtland since 1970. Through this system we traced the prescription pattern of 80 individuals who committed suicide from 1970 to 1984. Suicide patients obtained 1.5 times more prescription drugs than 80 matched controls, mainly psychotropics and vitamins. During the 3 months prior to the suicide, half of the patients had received medical attention and 73% of the women and 40% of the men had obtained prescription drugs, in one-third from the psychiatric department. While 53% and 29%, respectively, obtained psychotropic drugs, only 13% and 9% respectively were prescribed antidepressants, often in low doses. People who will commit suicide often seek medical help. The low rate of antidepressant prescription in patients committing suicide probably reflects insufficient diagnosis and treatment of depressive disorders. It is urgent--for the individual as well as for society--that diagnostic and pharmacotherapeutic routines be improved. Language: en
TL;DR: The data suggest that increased cortisol secretion is a characteristic of the depressed state in mixed manics, although pure manics may also have increased DST nonsuppression.
Abstract: There is little information about hypothalamic-pituitary-adrenocortical (HPA) axis function in mania, particularly in mixed states. We therefore investigated HPA function and its relationship to clinical state in 19 hospitalized manic patients meeting Schedule for Affective Disorders and Schizophrenia - Research Diagnostic Criteria for acute manic episodes, compared patients with and without a mixed presentation, and examined correlations between HPA activity and behavior. Data were available from 13-16 patients. Behavioral and biochemical analyses were conducted during a 15-d placebo period. Patients with mania had elevated cerebrospinal fluid (CSF) and urinary free cortisol excretion compared with healthy subjects, and did not differ from depressed patients in any cortisol measures. Mixed manics had significantly higher morning plasma cortisol, postdexamethasone plasma cortisol and CSF cortisol than pure manics. Five of 7 mixed manics and 3 of 9 pure manics were dexamethasone suppression test (DST) nonsuppressors. Afternoon plasma cortisol and CSF cortisol correlated significantly with depressed mood; urinary free cortisol correlated with anxiety. None of the cortisol measures correlated with mania or agitation scores. These data suggest that increased cortisol secretion is a characteristic of the depressed state in mixed manics, although pure manics may also have increased DST nonsuppression.
TL;DR: These results are consistent with several lines of evidence implicating a role for the cerebellar vermis in affective disorders and provide the first MR documentation of the differential effects of aging on posterior fossa morphology in normal subjects compared with patients with major depression.
Abstract: High-field magnetic resonance (MR) images were used to study posterior fossa morphology in 27 patients with major depression and 36 normal control subjects. Depressed patients demonstrated smaller brain stem and cerebellar vermis than controls. These differences were highly significant for the anterior cerebellar vermis and medulla. There was also a striking age-related decline in midbrain size in depressed patients as well as in controls. Our results are consistent with several lines of evidence implicating a role for the cerebellar vermis in affective disorders and, in addition, provide the first MR documentation of the differential effects of aging on posterior fossa morphology in normal subjects compared with patients with major depression.
TL;DR: Findings suggest the possibility of a specific relationship between B12 levels and severity of cognitive impairment in patients with AD.
Abstract: This study examines the relationship between folate, vitamin B12 and severity of cognitive impairment in patients with Alzheimer's disease (AD) as compared with other disorders associated with cognitive impairment. The patients were 97 consecutive referrals to an AD clinic. Forty patients had either possible or probable AD, 31 had other dementias (OD) and 26 had mild cognitive impairment (cognitively impaired, not demented; CIND). Patients had blood drawn for serum, red cell folate and B12, as well as other biochemical indicators of nutrition, within 24 h of the Mini-Mental State Examination (MMSE). In the AD group, only B12 was significantly correlated with MMSE. Using regression analysis, B12 contributed significantly to variance in MMSE. There was no correlation between MMSE and serum, red cell folate or B12 in the OD or CIND group and no significant correlation between MMSE and other nutritional indices in any group. These findings suggest the possibility of a specific relationship between B12 levels and severity of cognitive impairment in patients with AD.
TL;DR: In assessing psychopathology in young adults an age‐adjusted child‐oriented instrument might be a good alternative to the existing adult‐oriented instruments, especially when one takes into account the problem of data comparability over time in longitudinal studies in which children are followed into adulthood.
Abstract: This study compares the screening capacity of an age-adjusted child-oriented questionnaire, the Young Adult Self Report (YASR) with two adult-oriented questionnaires, the General Health Questionnaire-28 (GHQ-28) and Symptom Checklist-90 (SCL-90) in a sample of young adults (18-25 years). The YASR performed just as well as the SCL-90 and both performed better than the GHQ-28. The relatively poor performance of the GHQ-28 compared with the YASR and SCL-90 could not be attributed to instrument characteristics or to the use of referral status as indicator of psychopathology. In assessing psychopathology in young adults an age-adjusted child-oriented instrument might be a good alternative to the existing adult-oriented instruments, especially when one takes into account the problem of data comparability over time in longitudinal studies in which children are followed into adulthood.
TL;DR: Findings confirm and strengthen prior reports of an association between depression and attempted suicide and current suicidal thinking.
Abstract: The relationships between symptoms and both prior suicide attempts and current suicidal thinking were examined in a sample of schizophrenics at 2 points in time. Fifty subjects meeting DSM-III criteria for schizophrenia were assessed within 1 week of admission, and 41 were reassessed at a 6-month follow-up. On admission, prior suicide attempts were significantly associated with current depression, female sex, lower education and more frequent hospitalization. The association with depression remained significant at follow-up. In addition, current suicidal thinking was associated with depression at both times but also with negative symptoms at time 1 and delusions and hallucinations at time 2. These findings confirm and strengthen prior reports of an association between depression and attempted suicide.
TL;DR: Analysis of spontaneous ADR reports to the Danish Committee on Adverse Drug Reactions during 1968–1991 shows the same ADR profile, although with a higher rate of neurological and psychiatric and a lower rate of hepatic reactions.
Abstract: Adverse drug reactions (ADR) to disulfiram treatment have been reported as single cases, but few systematic investigations exist In this study we analysed the spontaneous ADR reports to the Danish Committee on Adverse Drug Reactions during 1968–1991 In that period 154 ADRs to disulfiram were reported, mainly of hepatic, neurological, skin, and psychiatric reactions, in decreasing order of frequency The safety of disulfiram, estimated on the amount produced and the number of reactions reported, corresponds to an intermediate rate of adverse reactions (1 per 200–2000 treatment year) Over the 23-year period, 14 deaths were reported in Denmark and this corresponds to a rate of 1 per 25,000 treatment year; the chief cause was liver toxicity Reports to the WHO collaborating Centre for International Drug Monitoring in Uppsala, Sweden, showed the same ADR profile, although with a higher rate of neurological and psychiatric and a lower rate of hepatic reactions
The latency time from the start of treatment to the manifestion of the ADR differed according to organ Hepatitis occurred with a distinct peak after 2 months of treatment, skin reactions peaked after 2 weeks, and the rate of neurological ADR increased with duration of therapy The relation of skin reactions and hepatitis to nickel allergy is discussed, as is the dose-dependency of neuropathy
Concomitant disulfiram treatment affects the metabolism of several drugs and the dynamics of others, leading to a number of clinically important drug interactions The disulfiram drug interactions are reviewed
