The distribution of some risk factors on different psychiatric diseases in 1726 hospitalized patients were investigated within a prevalence study. To all tested factors there was a contrary behaviour of oligophrenic patients opposite to the group with a schizophrenia, organic and affective psychotics. Hypertension only was found more frequently in non psychotic psychopathia and oligophrenia than in psychosis. Therefore the prevalence of hypertriglyceridemia, hypercholesterinemia, diabetes, specific Ecg-changes, smoking of cigarettes and severe physical inactivity in oligophrenics was less except in all other group of diseases, also in consideration of the different frequency of psychopharmacal treatment. Electrocardiographical signs for coronary heart diseases also show a similar distribution of frequency. Likewise in psychiatric patients seems to be an agreement with the coronary morbidity and the somatic risk factors.

In 1969, a Pacific Northwest American Indian community cohort (n = 100) was interviewed for the presence of physical and psychiatric illnesses. The same community was studied again in 1988. This study describes the outcome among the original 100 subjects. The schedule for Affective Disorders and Schizophrenia Lifetime Version (SADS-L) served as the basic interview instrument, supplemented by data from medical records, death certificates, and medical and community informants. Twenty-five subjects had died, 13 from cardiovascular disorders and seven from alcohol-related illnesses. Among the 46 subjects re-interviewed, hypertension, heart disease, and diabetes had become significant sources of medical morbidity. Alcoholism was the most significant cause of psychiatric morbidity, particularly among males. This study indicates that greater attention should be focused upon prevention and treatment of alcoholism, cardiovascular disorders, and diabetes in this community and in other American Indian populations.

Immune mechanisms are thought to be important in a subpopulation of patients with schizophrenia. We examined the specificity of neural antibodies in patients with schizophrenia to identify a possible antigen. Serum antibodies from patients with schizophrenia and control subjects were tested for binding to protein extracts of human neuroblastoma cells by western blot. Protein antigens were characterised by aminoterminal and internal aminoacid sequence analysis. 14 of 32 (44%) otherwise healthy patients with schizophrenia had antibodies to a neuroblastoma protein of molecular weight 60 kDa. By partial sequence analysis, this protein was identified as the 60 kDa human heat-shock protein (hsp) that is the P1 mitochondrial protein, and which is 50% homologous to the mycobacterial 65 kDa hsp. Antigens that crossreact with hsp65 have been implicated in the pathogenesis of adjuvant-induced arthritis in rats and autoimmune diabetes in mice. Of 100 normal subjects or disease controls, antibodies to hsp60 were found in only 8 patients, all of whom had active infectious or inflammatory disease. Our results support the presence of abnormal immune reactivity involving hsp60 in a subset of patients with schizophrenia. The immune response may be related to the pathogenesis of the disease.

Pentasomy X mosaic in two adult sisters with non-insulin dependent diabetes mellitus is described. The younger sister had schizophrenia, and both were mentally retarded, but no apparent somatic abnormalities were found. Chromosome analyses revealed karyotype 45,X/46,XX/47,XXX/48,XXXX/49,XXXXX mosaic with a low frequency of aneuploidy on cultured peripheral lymphocytes and 46,XX on cultured skin fibroblasts in both sisters. The low frequency of X chromosome aberration may be responsible for the lack of somatic abnormalities and the long life in both sisters. The association of pentasomy X mosaicism and diabetes mellitus however appears to be coincidental.

The following article updates the GZD theory of schizophrenia (1) by showing that male transmission of risk, the parental age effect, racial differences in birth seasonality, the disturbed sex ratios in the offspring of schizophrenic mothers and the association between diabetes and schizophrenia are explained by changes to zinc homeostasis. A genetic component to the disorder is now seen as unnecessary, transmission of risk by either parent, and twin concordance differences can be explained by other means. The primary site of action of GZD is identified as the putative ZFY sex determining system. Evidence suggesting that other mental disorders might be caused by GZD is also discussed.

Six cases of acute renal failure (ARF) due to rhabdomyolysis were experienced between 1984 and 1989. Patients' ages ranged from 33 to 92 years old (average ages 61) and all were male. The causes of rhabdomyolysis were as follows: one crush syndrome, one acute arterial occlusion, one diabetic hyperosmolar nonketotic coma and three cases of malignant syndrome due to neuroleptica (mainly haloperidol). Underlying diseases included, one case of abdominal aneurysm, two cases of diabetes mellitus, two cases of schizophrenia and one case of reactive psychosis. Dehydration was considered as an important factor in the onset of rhabdomyolysis and ARF, because it was observed in 4 of the cases in this study. In all cases, the serum levels of potassium, phosphorus and uric acid as well as myoglobin and myogenic enzymes increased markedly. In patients with myoglobinuric ARF, severe metabolic acidosis and hypocalcemia in the oliguric phase and hypercalcemia in the diuretic phase were prominent. Muscle biopsy showed myolytic degeneration in 2 of 4 cases. Five cases were treated with hemodialysis and one case was managed conservatively. All 6 cases had relatively good prognosis. However, 3 cases with malignant syndrome showed outcomes more severe than in the other 3 cases without such syndrome.

1. Genetic databases are an expanding and readily accessible repository of information on the mapping and sequencing of the human genome, and that of other model organisms. The integration and application of this information to neuropsychiatric disease is illustrated using neuroendocrine and neuropharmacologic data, computerized and other genetic databases. 2. This computer-assisted integrated approach to knowledge structures permits the rapid generation of hypotheses, the prompt identification of candidate gene loci, an explanation for genetic heterogeneity, and strategies for the use of potential linked markers. 3. Results using this integrated search strategy demonstrate that over 30 candidate loci for neuropsychiatric disease have currently been mapped in man (spread over 14 chromosomes in the human genome), and that at least 6 homologous loci have been mapped in mouse. 4. Using a metabolic pathway approach, it can be shown that the best current candidate gene locus for a subtype of schizophrenia located on chromosome 5q11-13 (HGML10 # SCZD1 and OMIM #181510) is in the serotonergic pathway, i.e. a receptor for 5-hydroxytryptamine (subtype 1A; HGML10 #HTR1A) which also maps in the same chromosomal region. 5. Parallels are suggested between inborn errors of metabolic pathways in the somatic endocrine system (using insulin-dependent diabetes mellitus as a paradigm) and the neurotransmitter and hormonal systems within the brain. 6. A subset of neuropsychiatric disorders may thus be viewed as inborn errors of cerebral metabolic pathways primarily affecting the biogenic amine pathways.

American former prisoners of war (POWs) are an aging group who seek health care with increasing frequency. To examine the prevalence of long-term physical and emotional consequences of captivity in this population, the authors analyzed medical and psychiatric examination data for 426 former POWs. Detailed psychiatric diagnostic criteria were used to assess the POWs' mental health. Compared with general population groups, POWs had moderately elevated lifetime prevalence rates of depressive disorders and greatly elevated rates of posttraumatic stress disorder (PTSD), although their rates of hypertension, diabetes, myocardial infarction, bipolar disorder, schizophrenia, and alcoholism were not elevated. POWs who lost more than 35 percent of their body weight during captivity had higher rates of anxiety disorder, depressive disorders, PTSD, and schizophrenia, compared with other POWs.

These data, in combination with the literature reviewed above, demonstrate several important points for those who work in clinics where elders with sexual problems are seen: 1. The currently available literature on the relation of sexual dysfunction to psychiatric disorder in the elderly is not extensive, and much of the literature is limited by methodologic flaws. There is a clear need for improved research methods and a broader data base. Nonetheless, the existing studies indicate that psychologic disorders are found in conjunction with sexual dysfunction commonly enough that clinicians must regularly assess for their presence. 2. The cause of sexual problems is seldom simple or entirely clear. Diagnoses of psychologic concerns and disorders that might relate to sexual dysfunction are common, and most older patients' sexual dysfunction will have a mixed cause, with both medical and psychologic factors playing an important role in the development and maintenance of sexual dysfunction. In our series of patients, 52.8% had diagnosable psychologic difficulties that were assumed to be related to the sexual difficulties. Another large group (39.9%) had psychologic factors (although not diagnosable disorders) that were assumed to contribute to the current manifestation of sexual dysfunction. Thus, it should not be assumed, as it was in years past, that when one likely causative factor is identified (e.g, diabetes, performance anxiety, or depression), the cause of the dysfunction has been identified. 3. The types of psychopathology seen in sex clinics are typically fairly limited, with the largest proportions by far being alcohol abuse or depression (50.1% and 62.1%, respectively, of all psychologic diagnoses in our clinic). Major psychopathology is relatively underrepresented. We suspect this underrepresentation does not reflect a true population characteristic but, rather, a selection difference; patients with major psychopathology such as schizophrenia either do not complain of sexual dysfunction to their therapists or are not referred for treatment by their therapists. 4. The presenting complaints of patients with a psychologic disorder do not differ significantly from those of patients without a psychologic disorder in a general sexual dysfunction clinic. 5. Treatment outcome, especially the rate of successful treatment, does not differ between those with and those without psychologic diagnoses when physicians and psychologists work together on an interdisciplinary team to offer treatment.(ABSTRACT TRUNCATED AT 400 WORDS)

Medication noncompliance occurs among as many as one-third to one-half of all medical and psychiatric outpatients. Noncompliance has serious consequences for individuals diagnosed with schizophrenia, often resulting in higher rates of relapse and rehospitalization, and poorer community adjustment. Health education interventions have been shown to be effective in promoting compliance among patients with chronic medical illness such as hypertension or diabetes, but there have been few randomized trials of this approach among patients with chronic psychiatric disorders. This paper presents the results of an application of health education among a group of male psychiatric outpatients. Two interventions were developed which used health education techniques to 1) engage families or significant others as active participants in the aftercare process, and 2) train patients to become effective health care consumers. A total of 418 individuals participated in a six-month trial over a four-year study. Both interventions significantly improved medication compliance among those who received them. The results show that comparatively brief interventions can significantly alter medication compliance behavior and improve the quality of life for patients with chronic psychiatric disorders.
