Death rate and causes of death during a mean period of 5.8 years were investigated in 250 male inpatients with psychotic disorders (DSM-III). Fifty patients died during the observation period. Suicide was confirmed in 11 of these patients and could not be excluded in 7 cases, where the cause of death was reported as uncertain. Clinical and neurobiological characteristics (DST-non-suppression, CSF proteins, and monoamine metabolites) were compared in patients who committed suicide and non-suicide patients of the same age, with or without suicidal behaviour. A highly increased mortality rate was seen among the patients and the rate of suicide was more than 20 times higher than that expected in a normal population of the same age. The estimated annual incidence of suicide was 2.5%, 1.3%, 1.0% and 0.4% for patients with bipolar disorder, paranoid psychosis, major depression and schizophrenic disorder, respectively. The following factors were significantly positively correlated with completed suicide: depressive mood, elated mood, paranoid ideas, and paternal age. All suicides had previously shown suicidal behaviour and the suicide occurred during or shortly after a period of hospitalisation. No correlations were found with age at onset of illness, duration of illness, substance abuse or neurobiological parameters.
Possible psychiatric implications of impairment of the blood-brain barrier were studied in 25 patients with paranoid psychosis. Determination of the ratio between the albumin concentrations in cerebrospinal fluid and serum showed increased, indicating impairment of the blood-brain barrier, in seven patients and normal values in 18. The two groups were compared for clinical, pharmacokinetic, neurophysiological and anamnestic variables. The highly significant finding that onset of psychosis had occurred, on average, 20 years earlier in the patients with impairment of the blood-brain barrier than in those without suggests that such impairment might influence the development of psychosis in predisposed individuals.
Eleven patients from a lithium-treated cohort of 64 patients with major affective disorder (DSM-III) were investigated after a mean of 6.7 years on lithium prophylaxis and reinvestigated 7 years later, at which point they had discontinued lithium for a mean of 2.3 years. Therapeutic outcome was compared in the 11 discontinuers and 20 continuers on lithium from the same cohort, matched for sex, age, and mental status on admission to the study. Ratings of psychopathology (CPRS) at the end of the 7-year follow-up period showed that the only significant difference between the patient categories was a higher frequency of reported autonomic disturbances and worry over trifles in the discontinuers. Daily doses of neuroleptic drugs were significantly higher in discontinuers than in controls by the end of the study. Alternative concomitant treatment outside conventional medicine was sought by 45% of the discontinuers, whereas no lithium-treated control reported the need for such additional therapeutic measures.
Thirty-seven patients with major affective disorders according to DSM-III and on continuous lithium treatment were followed during a 7-year period. Outcome was assessed by use of the Comprehensive Psychopathological Rating Scale and by the need for additional psychotropic medication and for hospital and outpatient care. Anamnestic variables and patient's attitudes to their lithium medication were also included in the analysis of outcome, as were laboratory data, including lithium parameters. An increase in psychopathology was demonstrated in a significant number of patients and was attributed mainly to an increase in the depressive symptoms, with a significant increase in the rated scores for fatiguability, pessimistic thoughts, reduced sleep, and inner tension. Suicidal thoughts were common, but no suicide attempts were made. A significant number of patients complained of failing memory, but no significant progression was demonstrated during the 7-year study period. The increase in the depressive symptoms was closely correlated with the number of hospital admissions for depressive recurrence and with the number of days in hospital. The following factors showed a significant relationship with the increase in depressive symptoms: serum lithium levels, large increase in the elimination half-life of lithium, low level of social functioning, low TSH values, and need of concomitant administration of antidepressants and benzodiazepines.
A case report is given of a pair of monozygotic twin girls with neurofibromatosis caused by a new mutation. The symptomatology was dominated by a neurofibrosarcoma on the leg of one twin and by a large plexiform neurofibroma on the neck of the other twin. Otherwise, the disease showed similar, although not identical or mirror-image distribution of subcutaneous neurofibromas and café-au-lait spots. The twins had identical HLA and blood group antigens and the same chromosome aberration. These case reports indicate that nonhereditary factors may influence the manifestations of neurofibromatosis. A review of the literature on monozygotic twins with neurofibromatosis is given.
The concept of cycloid psychosis has gained increasing acceptance during recent decades. Using the diagnostic criteria of Perris and Brockington, an intelligible delineation of a group of patients has been obtained. Few epidemiological data on cycloid psychosis have been reported so far. The objective of the present study was to describe the one-year incidence of cycloid psychosis in a clinical sample. The diagnostic registers of all patients hospitalized for a functional or an organic psychosis and discharged in the year 1983, in Lund, Sweden were investigated. 514 patients were identified of whom 83 were admitted to hospital for the first time. 29 of these patients had a functional psychosis and were below the age of 50. In this age group 7 cases (4 women, 3 men) fulfilled the diagnostic criteria of cycloid psychosis and thus constituted almost one fourth of all first admissions of functional psychoses that year. The one-year incidence for first admission in cycloid psychosis was 5.0 per 100,000 inhabitants in women and 3.6 per 100,000 inhabitants in men within the age group 15-50 years in the catchment area of 163,175 persons. We conclude that cycloid psychosis constitutes a considerable proportion of functional psychoses in both sexes.
