Bipolar manic-depressive illness is a chronic disease in which patients experience recurrent episodes of mania and depression. Patients often change from a nonverbal, retarded depression of many months' duration to a hyperactive, psychotic, manic condition during the switch. The time required for the switch from depression into mania varies from 5 minutes to a couple of days. Just before it happens, pateints experience marked insomnia and decreased rapid eye movement sleep. It is hypothesized that specific changes in brain monoamine metabolism precede the switch. Alterations in neurotransmitter metabolites, as measured in urine and cerebrospinal fluid, may precede and accompany it. The switch into mania can be precipitated by environmental stresses or by drugs that act by increasing functional brain monoamines. Drugs that reverse the manic state all share the common property of affecting biogenic amines. The switch into mania is viewed in the context of a longitudinal cyclic process and may be further studied with specific pharmacologic agents that block drug-induced maniclike states in man.

Twenty-one patients with brucellosis wereinvestigated. Four patients with the classical manifestations of acute brucellosis presented no problems in diagnosis. The other 17 patients suffered from chronic disease and had no history of any acute episode of brucellosis. The most common symptoms in this group were tiredness, fatigue, depression, arthralgia and muscular pains. Abdominal pain and pain in the temperomandibular joints were marked in some patients. Most of these patients had been receiving psychiatric treatment. Clinical examination was largely negative, but lymphadenopathy was found in 9 cases. Brucella meningo-encephalitis was diagnosed in 7 patients who complained of severe headache. Problems in the diagnosis of chronic brucellosis with an insidious onset are discussed.

Because of the increased incidence of chronic disease and other health problems associated with aging, chronic pain is a common companion for the elderly. Pain is of great clinical importance, often associated with disability, loss of independence, and reduced quality of life. A fact that is of interest to psychiatric nurses is that many elderly with complaints of chronic pain also exhibit signs and symptoms of depressive disorders. Treating chronic pain conditions is complex and difficult, and health-care professionals are increasingly recognizing that psychological factors are often involved in the development and continuation of chronic pain problems. Depression is one of these influential variables. Increased understanding of the role of depression in the etiology and maintenance of chronic pain can improve assessment and intervention for the elderly with chronic pain complaints.

Overall 180 children aged 3 months to 12 years with acute and chronic hepatitis B and delta were examined for macrophagal function. Chemotaxis, saturation with esterase, the content of nuclear RNA were estimated, antigens of HB virus in these cells were identified as well. The data obtained attest to the correlation between the degree of macrophagal function disorders and the gravity of acute virus hepatitis. The chronic disease is characterized by stable depression of mononuclear cells with a tendency toward deeper depression of their function in patients with virus hepatitis delta as well as a higher rate of HBsAg and HBeAg demonstration in these cells. The authors provide evidence for advisability of the use of BCG vaccine and tactivin in patients with the chronic disease, since they improve macrophagal function, promote the inhibition of HB-virus replication and the onset of a stable remission in patients with chronic hepatitis B and delta.

Assessment of physical and psychosocial dysfunction is recognized as essential in chronic pain patient evaluation. One instrument, the Sickness Impact Profile (SIP), has demonstrated good reliability and validity as a measure of dysfunction among chronic pain patients. An alternate measure, the Chronic Illness Problem Inventory (CIPI), is shorter and more easily scored than the SIP, but as yet has not been applied widely to chronic pain problems. In the present study, 95 chronic low back pain patients completed the SIP, the CIPI, activity diaries, the McGill Pain Questionnaire (MPQ), and the Center for Epidemiologic Studies-Depression scale (CES-D), before participating in a chronic pain treatment study. Overt pain behaviors were also coded from videotapes of a standardized assessment protocol. Seventy-five subjects completed the measures post-treatment. The results indicate that although the SIP and the CIPI are significantly correlated and appear to be measuring similar constructs, there is also substantial unshared variance between them, suggesting that they may tap somewhat different aspects of dysfunction in chronic pain. The CIPI shows promise as a useful alternative measure of dysfunction in chronic low back pain patients, but requires further validation for this purpose.

We evaluated, among depressed medical patients who are high utilizers of health care, whether improved vs unimproved depression is associated with differences in the course of functional disability. At baseline, 6 months, and 12 months, depression and disability were assessed among a sample of enrollees in health maintenance organizations (N = 145) in the top decile of users of ambulatory health care who exceeded the 70th percentile of health maintenance organization population norms for depression. Improved depression was defined as a reduction of at least one third in depressive symptoms averaged across the two follow-up times. At the 12-month follow-up, persons with severe-improved depression experienced a 36% reduction in disability days (79 days per year to 51 days per year) and a 45% reduction in disability score. Persons with moderate-improved depression experienced a 72% reduction in disability days (62 days per year to 18 days per year) and a 40% reduction in disability score. In contrast, persons with severe-unimproved depression reported 134 disability days per year at baseline, while persons with moderate-unimproved depression reported 77 disability days per year at baseline. Neither group with unimproved depression showed improvement in either disability days or disability score during the 1-year follow-up period. High utilizers of health care with severe-unimproved depression were more likely to have current major depression and to be unemployed. Improved (relative to unimproved) depression was associated with borderline differences in the severity of physical disease and in the percent married. We conclude that depression and disability showed synchrony in change over time. However, depression and disability may show synchrony in change with disability because both depression and disability are controlled by some other factor that influences the chronicity of depression (eg, chronic disease or personality disorder). The finding of synchronous change of depression and disability provides a rationale for randomized controlled trials of depression treatments among depressed and disabled medical patients to determine whether psychiatric intervention might improve functional status in such patients. Such research is needed to determine whether there is a causal relationship between depression offset and reductions in functional disability.

This paper re-examines the association between menopause and depression using data from a study in which 477 women were interviewed 6 times over a 3-year period. Menopause is examined as one of a series of factors which may increase the risk of depression for women in middle age, such as children leaving home, the death and illness of family members, the stresses of daily living, health and the onset of chronic disease. Rather than hormonal changes, it seems to be her health coupled with the shifts and stresses of family life in a woman's menopausal years which may trigger her depression.

Using population-based automated pharmacy data, patterns of use of selected prescription medications during a 1 year time period identified by a consensus judgement process were used to construct a measure of chronic disease status (Chronic Disease Score). This score was evaluated in terms of its stability over time and its association with other health status measures. In a pilot test sample of high utilizers of ambulatory health care well known to their physicians (n = 219), Chronic Disease Score (CDS) was correlated with physician ratings of physical disease severity (r = 0.57). In a second random sample of patients (n = 722), its correlation with physician-rated disease severity was 0.46. In a total population analysis (n = 122,911), it was found to predict hospitalization and mortality in the following year after controlling for age, gender and health care visits. In a population sample (n = 790), CDS showed high year to year stability (r = 0.74). Based on health survey data, CDS showed a moderate association with self rated health status and self reported disability. Unlike self-rated health status and health care utilization, CDS was not associated with depression or anxiety. We conclude that scoring automated pharmacy data can provide a stable measure of chronic disease status that, after controlling for health care utilization, is associated with physician-rated disease severity, patient-rated health status, and predicts subsequent mortality and hospitalization rates. Specific methods of scoring automated pharmacy data to measure global chronic disease status may require adaptation to local prescribing practices. Scoring might be improved by empirical estimation of weighting factors to optimize prediction of mortality and other health status measures.

This study examined age differences in the quality of self-report data in patients with chronic disease conditions (hypertension, diabetes, heart disease, depression). Data are from 2,304 patients in three health care systems in Los Angeles, Chicago, and Boston. Results support the idea that self-report health data can be gathered from older and younger patients without significant decrements in data quality. Specifically, results showed: (1) small decreases in the reliability of multi-item measures with age, primarily occurring in balanced scales; (2) little evidence of differences among age groups in response set or the tendency to respond "don't know" or "uncertain," although older patients had a greater tendency to respond in a socially desirable manner; (3) higher item nonresponse in older patients; (4) little variation in item nonresponse by type of question or question placement; (5) generally high panel retention in all age groups, supporting the value of repeated follow-up; and (6) similar known-groups validity across age groups.

Vigorous physical activity can improve the health of both adults and children. Among adults, regular physical activity can reduce risk for chronic diseases such as coronary heart disease, hypertension, noninsulin-dependent diabetes mellitus, colon cancer, and depression, as well as lower all-cause death rates (1,2). Among children, regular physical activity can reduce chronic disease risk factors such as obesity, elevated cholesterol, and hypertension (3). Physical activity patterns established during childhood may extend into adulthood (4). This report examines the prevalence of vigorous physical activity among U.S. students in grades 9-12.
