Substance abuse and dependence in physicians: the Missouri Physicians' Health Program.

Substance abuse and dependence (alcohol and drugs) are behavioral disorders and treatable medical diseases. There is growing concern in the medical community for physicians impaired by these diseases. The Missouri Physicians' Health Program has been established to help impaired physicians return to healthy personal and professional lives. This confidential voluntary program of early referral, intervention, treatment, monitoring, and advocacy has been highly successful. The average recovery rate in this study of 146 participants was 94%.

The impaired physician, Part II: Missouri State Physicians Health Program.

Missouri Physicians Health Program (MPHP) was established to help impaired physicians return to healthy personal and professional lives. One percent of Missouri physicians will suffer some sort of impairment; ie: substance abuse, or dependency of drugs or alcohol within a year. This is a confidential voluntary program. This program of early referral, intervention, treatment and monitoring advocacy has been highly successful. The average recovery rate in this study of 75 participants was 92%.

Substance abuse and dependence in physicians: an overview of the effects of alcohol and drug abuse.

Substance abuse and dependence (alcohol and drugs) are behavioral disorders and treatable medical diseases. Early intervention followed by appropriate treatment can often help return physicians to healthy personal and professional lives. Current scientific evidence suggests the prevalence of substance abuse or dependence among the medical profession over a lifetime is approximately 10-15%, slightly in excess of the general population. The initiation of intervention is critical and ultimately may be lifesaving.

Specificity of mixed affective states: clinical comparison of dysphoric mania and agitated depression.

To investigate the clinical specificity of mixed affective states, we compared clinical characteristics of mixed (dysphoric) manics to those of agitated depressed patients. The subjects were inpatients studied in the NIMH Clinical Research Branch Collaborative Study on the Psychobiology of Depression, Biological Studies. Behavior and symptom ratings for depressive and manic symptoms were obtained during a 15-day placebo washout period. Patients with agitated depression were compared to those in acute manic episodes with and without prominent depressive symptoms. Mania ratings clearly distinguished agitated depressed from mixed manic patients. Concerning depression and general psychopathology, mixed manics had more severe agitation, hostility and cognitive impairment than did agitated depressed patients. Depressed mood and anxiety did not differ significantly between the two groups. Nurse ratings for depression and anxiety, based on ward behavior, were similar for mixed manics and agitated depressed patients, while physician-interview rated depression and anxiety were higher in agitated depressed patients. These data support the existence of superimposed depressive and manic syndromes in mixed manics.

Response to treatment with antidepressants of patients with severe or moderate nonpsychotic depression and of patients with psychotic depression.

Hospitalized patients were divided into nonpsychotic severely depressed (N = 53), nonpsychotic moderately depressed (N = 54), and psychotic depressed (N = 25) groups and treated with either imipramine or amitriptyline, up to 250 mg/day, for 4 weeks. Good response occurred in 39% of the 38 severely depressed, 67% of the 49 moderately depressed, and 32% of the 19 psychotic depressed patients who completed treatment. The response of the patients with nonpsychotic severe depression did not differ significantly from the response of those with psychotic depression, and both groups fared worse than the group with nonpsychotic moderate depression.

Stress, depression, and mania: relationship between perceived role of stressful events and clinical and biochemical characteristics.

We investigated the perceived role of stressful events in episodes of major affective disorder in patients studied in the NIMH Clinical Research Branch Collaborative Program on the Psychobiology of Depression (Biological Studies). Using items from the Schedule for Affective Disorders and Schizophrenia (SADS), episodes were divided into environment-sensitive (high perceived role of stressful events) and autonomous (minimal or no perceived role of stressful events). Patients with environment-sensitive episodes had fewer previous episodes and a longer index episode. The groups did not differ with respect to age, gender, education, socioeconomic group, diagnosis, severity of illness, or eventual response to treatment. Unipolar depressed patients with environment-sensitive episodes had lower CSF 5-HIAA than those with autonomous episodes. Among bipolar depressed patients, those with autonomous episodes had elevated excretion of O-methylated catecholamine metabolites and of epinephrine, while those with environment-sensitive episodes had normal excretion of catecholamines and metabolites. Manic subjects with environment-sensitive episodes had elevated norepinephrine excretion, while this was normal in manics with autonomous episodes. Relationships between environmental sensitivity of affective episodes and neurotransmitter function therefore appear to be related to the type of episode.

Cortisol measures in primary major depressive disorder with hypersomnia or appetite increase.

Morning plasma cortisol response to the 1 mg dexamethasone suppression test along with cortisol levels in blood, cerebrospinal fluid (CSF), and urine were measured in hospitalized male and female patients with primary major depressive disorder who reported hypersomnia (n = 23), or increase in appetite (n = 22). Comparisons were drawn to cortisol levels in patients with primary major depressive disorder who did not report hypersomnia or appetite increase (n = 23) and to normal controls (n = 23), all age- and sex-matched. Depressives with hypersomnia or increased appetite showed higher than normal 24-h urinary free cortisol concentrations. Depressed patients without hypersomnia or appetite increase had in addition to elevated free urinary cortisol concentrations higher than normal morning plasma cortisol levels before and after dexamethasone administration and a higher incidence of cortisol non-suppression after dexamethasone compared to normal subjects. The findings provide preliminary evidence that HPA activation in depression is diminished in the presence of hypersomnia and/or an increased appetite. Studies of the hypothalamic-pituitary-adrenal axis may be useful for differentiating subtypes of depression characterized by hypersomnia or enhanced appetite.

Sociodemographic and prior clinical course characteristics associated with treatment response in depressed patients.

A sociodemographic and clinical picture is presented of 82 depressed subjects who had an unequivocal response or lack of response to treatment with amitriptyline or imipramine. Patients with less severe depressive illness were found more likely to respond to treatment, while those with psychotic features were more likely to be treatment resistant. Sociodemographic and other prior and current clinical course variables were not predictive of treatment response in depressed patients.

The timing, specificity and clinical prediction of tricyclic drug effects in depression.

This research was aimed at studying the rate of action of tricyclic drugs in depressive disorders, specifying the behavioural effects associated with recovery, and predicting clinical response. The research design involved comparison of a recovered group with a group treated for the equivalent four weeks, who showed minimal to no response. The findings indicated significant differences in baseline characteristics between responders and non-responders. Further, the drugs were found to act early in the responders, within the first week of treatment. Specific changes at one week which distinguished responder and non-responder groups occurred in the disturbed affects, and in cognitive functioning. Improvements also occurred in somatic symptoms, but these latter changes were general and not associated with later recovery. At 2 1/2 weeks, all facets of the depressed condition showed positive change in the responders. Implications of the results for assessing rate of tricyclic drug actions, their effects on the interaction of affect and neurochemistry, and the practical application of the results for the clinical situation, are discussed.

Diagnosis and treatment of mixed mania.

In a study of 19 manic patients, the authors found that eight suffered from mixed mania, a condition in which depressive symptoms are found in the context of classic manic features. The presence of a mixed manic state predicted at least a slower and possibly a poor response to lithium therapy. The authors suggest that the delineation of a subgroup of mixed manic patients might help to identify potential lithium-resistant patients.

Mania. Diagnosis, state measurement and prediction of treatment response.

The phenomenology of the manic state and its response to lithium drug treatment were intensively studied as part of a larger NIMH Clinical Research Branch Collaborative Program on the Psychobiology of Depression. In view of the weaknesses in current methods for measuring the components of the manic state, a new instrument was developed, the Manic Diagnostic and Severity Scale (MADS). Its sensitivity in diagnosis and in measuring change was compared to other scales already in use. Finally baseline clinical data is presented that suggests that the presence of a "mixed" manic state is a predictor of lack of clinical response to lithium treatment.

Association of alcoholism and antisocial personality in a narcotic-dependent population: the Lexington addicts.

Men with antisocial personality have a higher prevalence of alcoholism than men without. This relationship was examined in a narcotic-dependent sample, and it was found that narcotic-dependent men with antisocial personality had a rate of alcoholism comparable to that of narcotic-dependent men without antisocial personality. The methodological and clinical explanations for this finding are discussed along with the neurophysiological implications.

Psychiatric diagnosis and prediction of drug and alcohol dependence.

Some sociodemographic variables that have distinguished the future addict from the general population have not been found to predict outcome in those already dependent. This study demonstrates that a past history of specific psychiatric disorders is predictive of outcome in narcotic addicts. Future research should focus on interactions among past histories, past and present personality and motivation, and situational variables in the search for reliable clinical prognostic factors.

Is the major histocompatibility complex linked to genes that increase susceptibility to affective disorder? A critical appraisal.

The evidence implicating genes linked to the major histocompatibility complex in the pathogenesis of affective disorder is reviewed, and 10 new multiplex families containing 26 affected siblings are presented. It is shown that when the data are properly analyzed by not dismantling multiplex sibships into all possible sib pairs, no individual data set presents compelling evidence of linkage. The present study is also negative. However, pooling all published families results in moderate evidence for nonrandom assortment.

Psychiatric illness in male and female narcotic addicts.

This report describes the results of initial psychiatric interviews on 100 male and 100 female narcotic addicts who were matched by age, race, and geographic origin. The majority met criteria for antisocial personality whereas about one in four males and one in seven females met criteria for alcoholism. Between one-third and one-half of the subjects met criteria for secondary depression. Bipolar affective disorder and schizophrenia rates were not elevated. Males significantly more often were diagnosed as having antisocial personality and alcoholism whereas females significantly more often were diagnosed as having a non-drug depression. Treatment implications of the observed differences between males and females are discussed.
