Cocaine use and dependence in young adults: associated psychiatric disorders and personality traits.

Current and lifetime prevalence of substance use and psychiatric disorders was determined by administering the NIMH-DIS, revised to cover DSM-III-R diagnoses, to a sample of 1007 young adults. Personality and affectivity were measured also. Increased rate of any Substance Use Disorder was related to use of cocaine more than 5 times over the lifetime regardless of whether or not criteria for Cocaine Dependence were met. Increased rate of any Affective Disorder was related to dependence in those who used cocaine more than 5 times. Cocaine use was associated with increased neuroticism, psychoticism and negative affect.

Migraine, major depression and panic disorder: a prospective epidemiologic study of young adults.

We examined prospectively the risk for major depression (MDD) and panic disorder in persons with prior history of migraine. A random sample of 995 young adults was interviewed in 1989 and reinterviewed in 1990. A history of migraine at baseline increased fourfold the risk for MDD during the follow-up interval. A history of any anxiety disorder exacerbated the risk for MDD in persons with migraine. Persons with a history of migraine were twelve times more likely to become cases of panic disorder than those with no history of migraine. The risk for MDD and/or panic disorder was unrelated to whether or not migraine was active during the year preceding the baseline interview or in remission for more than one year. The findings suggest that migraine, major depression and anxiety disorders might share common predispositions.

Nicotine withdrawal symptoms and psychiatric disorders: findings from an epidemiologic study of young adults.

OBJECTIVE: Earlier, the authors reported on the association of nicotine dependence with major depression and anxiety disorders in a group of young adults. This report describes the occurrence of withdrawal symptoms and their sociodemographic and psychiatric correlates in persons in that group who tried unsuccessfully to abstain from smoking. METHOD: A random sample of 1,007 members of a health maintenance organization, 21-30 years old, were interviewed with a revised version of the NIMH Diagnostic Interview Schedule. Data on nicotine withdrawal came from a subset of 239 smokers who had tried unsuccessfully to quit or cut down on smoking. RESULTS: With two exceptions, each of the DSM-III-R nicotine withdrawal symptoms was reported by more than one-half of these smokers. Withdrawal symptoms were more severe in white than in black smokers but were unrelated to sex, educational level, or marital status. Persons with histories of major depression or any anxiety disorder reported more severe withdrawal symptoms than persons with neither of these disorders. Severity of withdrawal, or any specific symptom, did not account for the association between major depression and continued smoking. Furthermore, severity of withdrawal was unrelated to continued smoking. CONCLUSIONS: While the long-term clinical significance of nicotine withdrawal is unclear, the evidence indicates that in the general population, abstinence from smoking is associated with a variety of disturbances, including a craving for cigarettes, dysphoria, and symptoms of irritability or nervousness. In this study disturbances were more severe in persons with histories of major depression or anxiety disorders.

Posttraumatic stress disorder in an urban population of young adults: risk factors for chronicity.

OBJECTIVE: Despite progress in epidemiologic research on posttraumatic stress disorder (PTSD), little is known about factors that distinguish chronic from nonchronic PTSD. In a previous report, the authors identified a set of personal predispositions associated with PTSD following traumatic events in a general population sample of young adults. The purpose of this analysis was to identify characteristics of chronic PTSD and examine whether any of the suspected risk factors for PTSD was associated specifically with chronic PTSD. METHOD: A random sample of 1,007 21- to 30-year-old members of a large health maintenance organization in the Detroit area was interviewed, using the National Institute of Mental Health Diagnostic Interview Schedule (DIS), revised for DSM-III-R. The analysis was performed on data from 394 respondents who reported traumatic events, of whom 93 met criteria for PTSD. Chronic PTSD was defined as duration of symptoms for 1 year or more. RESULTS: Persons with chronic PTSD (N = 53) had, on the average, a significantly higher total number of PTSD symptoms and higher rates of overreactivity to stimuli that symbolized the stressor and interpersonal numbing than persons with nonchronic PTSD. The rates of one or more additional anxiety or affective disorders and a variety of medical conditions were higher in persons with chronic than nonchronic PTSD. Family history of antisocial behavior and female sex were associated specifically with chronic PTSD. CONCLUSIONS: The findings suggest that chronic PTSD may be associated with specific risk factors and clinical features. Longitudinal data on the course of PTSD are needed to determine whether the distinct features and the medical and psychiatric histories of persons with chronic PTSD are complications attendant on a chronic course or coexisting disturbances that inhibit recovery.

Migraine, suicidal ideation, and suicide attempts.

We examined the risk of suicide attempts and suicidal ideation separately in persons with (1) migraine with aura alone, (2) migraine with aura and coexisting major depression, (3) migraine without aura alone, and (4) migraine without aura and coexisting major depression. Persons with migraine with aura alone and migraine with aura and coexisting major depression had significantly higher rates of suicide attempts and suicidal ideation compared with persons with neither migraine nor major depression. The rates of suicide attempts and suicidal ideation in persons with migraine with aura and major depression were higher than the combined rates in persons with major depression alone and migraine with aura alone. In contrast, migraine without aura was not associated with an increased risk for suicide attempts and suicidal ideation.

The effect of very low birth weight and social risk on neurocognitive abilities at school age.

We tested the hypothesis that very low birth weight (VLBW < 1.5 kg) children would have significantly poorer neurocognitive abilities at school age than would normal birth weight full-term age mates, that differences would persist after control for neurologic impairment and social risk, and that VLBW would interact with social risk. Two hundred forty-nine VLBW children and a randomly selected sample of 363 normal birth weight age mates born 1977 through 1979 were tested at 8 years. A neurologic examination and tests of intelligence, language, speech, reading, mathematics, spelling, visual and fine motor abilities, and behavior were performed. Twenty-four (10%) VLBW had a major neurologic abnormality compared with none of the controls. VLBW had significantly poorer scores on all tests, with the exception of speech and the total behavior score. These differences persisted among VLBW children without major neurologic abnormality, with the exception of social competence, reading, and spelling. Even normal IQ, neurologically normal VLBW had significantly poorer scores than did controls in expressive language, memory, visuomotor, and fine motor function, and measures of hyperactivity. When social risk was controlled in multiple regression analyses, VLBW still had an adverse effect on all outcome measures with the exception of speech. Social risk was, however, the major determinant of outcome. We found an interaction between VLBW and social risk only in verbal IQ and in the opposite direction than hypothesized.

Traumatic events and posttraumatic stress disorder in an urban population of young adults.

To ascertain the prevalence of posttraumatic stress disorder (PTSD) and risk factors associated with it, we studied a random sample of 1007 young adults from a large health maintenance organization in the Detroit, Mich, area. The lifetime prevalence of exposure to traumatic events was 39.1%. The rate of PTSD in those who were exposed was 23.6%, yielding a lifetime prevalence in the sample of 9.2%. Persons with PTSD were at increased risk for other psychiatric disorders; PTSD had stronger associations with anxiety and affective disorders than with substance abuse or dependence. Risk factors for exposure to traumatic events included low education, male sex, early conduct problems, extraversion, and family history of psychiatric disorder or substance problems. Risk factors for PTSD following exposure included early separation from parents, neuroticism, preexisting anxiety or depression, and family history of anxiety. Life-style differences associated with differential exposure to situations that have a high risk for traumatic events and personal predispositions to the PTSD effects of traumatic events might be responsible for a substantial part of PTSD in this population.

Nicotine dependence, major depression, and anxiety in young adults.

To determine whether nicotine dependence, classified by level of severity, was associated with other substance dependence, major depression, and anxiety disorders, we studied a random sample of 1007 young adults in the Detroit (Mich) area using the National Institute of Mental Health Diagnostic Interview Schedule, revised according to DSM-III-R. The systematic coverage of DSM-III-R criteria of nicotine dependence provides an unprecedented opportunity to separate persons with nicotine dependence from the larger class of persons with a history of smoking and to examine the prevalence of psychiatric disorders among persons with nicotine dependence and among nondependent smokers. The lifetime prevalence of nicotine dependence was 20%. Nicotine dependence was associated with alcohol, cannabis, and cocaine dependence. Controlling for the effects of other substance dependencies, persons with nicotine dependence had higher rates of major depression and anxiety disorders. The strength of these associations varied by level of severity of nicotine dependence. Nondependent smokers had higher rates of other substance dependencies, but not of major depression or anxiety disorders.

Migraine, psychiatric disorders, and suicide attempts: an epidemiologic study of young adults.

To determine the prevalence of migraine and the risks for psychiatric disorders and suicide attempts associated with it, we studied a random sample of 1,007 young adults from a large Health Maintenance Organization in the Detroit, MI area. The lifetime prevalence of migraine was 7% in males and 16.3% in females. The rate of migraine was higher in persons with lower education and was equal in whites and blacks. Persons with migraine were at increased risk for affective and anxiety disorders, nicotine dependence, and alcohol or illicit drug abuse or dependence. There was a consistent trend toward higher psychiatric comorbidity in migraine with aura than in migraine without aura. Coexisting anxiety, which generally preceded migraine, was associated with a marked increase in the odds of major depression. Persons with migraine had higher rates of suicide attempts than persons without migraine. The odds ratio for suicide attempts, adjusted for coexisting major depression and other psychiatric and substance use disorders, in migraine with aura was 3.0 (95% confidence interval, 1.4-6.6). The coexistence of migraine with major depression, anxiety disorders, and suicide attempts has important clinical and research implications.

Public attitudes toward some changes in the division of labor in medicine.

This study examined public attitudes toward the delegation of medical tasks to nonphysician health workers. Data were obtained in household interviews of a probability sample of the adult residents of Cuyahoga County, Ohio (N = 808). The proportions of the sample giving approval to care from nonphysicians varied widely among the 18 tasks on which opinions were elicited. The results of the public survey were compared to those from an earlier national survey of physicians. Physicians' responses paralleled the responses of the lay public regarding most tasks. However, with respect to regular checkups on babies and prenatal checkups, markedly higher proportions of the physicians than the public were willing to delegate to nonphysicians. The analysis indicated that public attitudes toward task delegation in medical practice do not bear strong relationships to social status indicators, political self-designations, or preceived health status.

Chlorpropamide-induced changes in patients with hyperparathyroidism.

Ten patients with primary hyperparathyroidism were placed on a constant 30 mEq of calcium and 120 meq of sodium diet, and alterations in their calcium balance in response to standard oral doses of chlorpropamide were studied over a 4 day control period and a 4 day treatment period. The 10 patients treated with chlorpropamide significantly increased the urinary excretion of calcium and sodium and decreased the excretion of cyclic adenosine monophosphate (AMP). The serum calcium was lowered in six of the patients treated with chlorpropamide, and three of these patients, who had diabetes mellitus and either refused or were too ill for parathyroidectomy, continued to receive chlorpropamide for periods of 9 to 36 months. These three patients experienced prolonged lowering of the serum calcium level and became less confused, lethargic, and fatigued. The interrelationships between the chlorpropamide-induced changes in excretion of calcium, sodium, and cyclic AMP still must be clarified.

Work settings and job satisfaction: a study of primary care physicians and paramedical personnel.

This paper examines job satisfaction of primary care physicians and paramedical personnel in traditional office practices and in modern medical organizations. A series of two-way analyses of variance using work settings and occupational level as independent variables showed consistent effects of setting on job satisfaction. In modern organizational settings satisfaction with the work activity, with coworkers, and with income was lower than in traditional practices. Only with respect to income, were physicians, on the average, more satisfied than paramedical workers. The relationships between job satisfaction and the variety and complexity of work as well as ownership of work settings are analyzed and discussed.

The role of the nurse-practitioner in a pediatric team: patient definitions.

Patient conceptions and evaluations of the nurse-practitioner role were explored in a random sample of families who attended a pediatric office team comprising a pediatrician and a nurse-practitioner. Patients do not perceive the nurse to have expertise in an exclusive domain of health problems. Thus, the majority of patients do not consider her addition to the office to have improved on the doctor services. Although many patients took advantage of the opportunity to discuss with the nurse issues they regarded unworthy of the doctor's time, they did not value time spent with the nurse as meriting dispensing with some of the doctor time or the payment of an additional fee. The low value placed by patients on the diffuse area of "care" as opposed to the application of medical science hinders the prospects of public recognition of the nurse-practitioner. This applies particularly to the nurse-practitioner as a team member, where an explicit attempt is made to articulate the unique domains and boundaries of the various professionals.

Renal responses to PTH in patients with hormone-resistant (pseudo) hypoparathyroidism.

Five patients with pseudohypoparathyroidism were compared to normal subjects and patients with hypoparathyroidism in their ability to respond to the infusion of parathyroid hormone (PTH) by altering excretion of calcium, sodium, potassium, phosphate and bicarbonate. In patients with pseudohypoparathyroidism, impairment in renal responses to PTH was more generalized than has been recognized. The patterns of response varied from patient to patient. The most commonly observed abnormality, aside from lack of increase in urinary cyclic adenosine 5'-monophosphate (AMP) was failure to decrease the calcium to sodium clearance ratio, and indication of impaired renal calcium reabsorption. The responses which most closely approximated normal, including a normal decrease in the calcium to sodium clearance ratio, occurred in a patient (Case 1) who had the largest, although impaired, response in cyclic AMP excretion. Conversely, the most abnormal responses occurred in three patients (Cases 2, 4 and 5) who had the smallest increases in cyclic AMP excretion after the administration of PTH. The impaired renal reabsorption of calcium after the administration of PTH (lack of decrease in calcium to sodium clearance ratio) may, when present, be in part responsible for hypocalcemia.
