Abstract
OBJECTIVE The safety and efficacy of mecamylamine as a monotherapy in children and adolescents with Tourette's disorder (TD) was investigated in an 8-week multicenter, double-blind, placebo-controlled study. METHOD Eligible subjects included subjects with TD (DSM-IV), with a naturalistic mix of comorbid diagnoses, nonsmokers, aged 8 to 17 years, whose behavioral and emotional symptoms (according to parents) were more disturbing than tics. After a washout period of all psychotropic medication, subjects were randomly assigned to either mecamylamine (n = 29) or placebo (n = 32). Mecamylamine doses ranged from 2.5 to 7.5 mg/day. Primary efficacy measures included the Tourette's Disorder Scale-Clinician Rated (TODS-CR) and 21-point Clinical Global Improvement scale; secondary efficacy measures included the Yale Global Tic Severity Scale and a rage-attack scale (RAScal). RESULTS Of the 61 subjects who were randomized, 50 (82%) completed at least 3 weeks on medication and 38 (62%) completed the full 8-week trial. Study withdrawals included 12/29 on mecamylamine and 11/32 on placebo. For the total sample, mecamylamine was no more effective than placebo on any of the outcome measures. However, an item analysis of the TODS-CR suggested that mecamylamine may have reduced sudden mood changes and depression in moderately to severely affected subjects. Except for a slight increase in heart rate during the 1st week in both the mecamylamine and the placebo groups, there where no significant mecamylamine-related changes in vital signs, electrocardiogram, complete blood cell count, or blood chemistry values. CONCLUSIONS Mecamylamine, in doses up to 7.5 mg/day, is well tolerated in children and adolescents, but as a monotherapy it does not appear to be an effective treatment for tics or for the total spectrum of symptoms associated with TD. However, further studies should be conducted to investigate its possible therapeutic effects in subjects with comorbid mood disorders and as an adjunct to neuroleptic medication.

Abstract
In 1990s, it was found that GSAD is more common, more disabling, and more chronic than previously realized. For the first time, there are good data about a range of effective treatment options that can offer these patients substantial relief and protection from their disability.

Abstract
Self-reported past year use of alcohol, tobacco, marijuana, cocaine, and two controlled prescription substances (opiates, benzodiazepines); and self-reported lifetime substance abuse or dependence was estimated and compared for 12 specialties among 5,426 physicians participating in an anonymous mailed survey. Logistic regression models controlled for demographic and other characteristics that might explain observed specialty differences. Emergency medicine physicians used more illicit drugs. Psychiatrists used more benzodiazepines. Comparatively, pediatricians had overall low rates of use, as did surgeons, except for tobacco smoking. Anesthesiologists had higher use only for major opiates. Self-reported substance abuse and dependence were at highest levels among psychiatrists and emergency physicians, and lowest among surgeons. With evidence from studies such as this one, a specialty can organize prevention programs to address patterns of substance use specific to that specialty, the specialty characteristics of its members, and their unique practice environments that may contribute risk of substance abuse and dependence.

Abstract
OBJECTIVE This study evaluated the efficacy and safety of fixed doses of once-daily extended-release (XR) venlafaxine in outpatients with generalized anxiety disorder without concomitant major depressive disorder. METHOD Adult outpatients with generalized anxiety disorder but not major depressive disorder with total scores of 18 or higher on the Hamilton Rating Scale for Anxiety and scores of 2 or higher on its anxious mood and tension factors were eligible. Patients were randomly assigned to receive placebo or venlafaxine XR (75, 150, or 225 mg/day) for 8 weeks. Primary efficacy variables were final total and psychic anxiety factor scores on the Hamilton anxiety scale and final severity and global improvement item scores on the Clinical Global Impression (CGI) scale. RESULTS Of the 377 patients entering the study, 370 were included in a safety analysis and 349 in an efficacy analysis. Adjusted mean scores at 8 weeks (last-observation-carried-forward analysis) were significantly lower for one or more of the venlafaxine XR groups in four of four primary and three of four secondary outcome measures than for the placebo group. These included a change of 1.7 (versus 1.3) from baseline on CGI severity item scores and a final score of 2.2 (versus 2.6) on the CGI global improvement item. All doses of venlafaxine XR were well tolerated. CONCLUSIONS Venlafaxine XR is an effective and well-tolerated option for the short-term treatment of generalized anxiety disorder in outpatients without major depressive disorder.

Abstract
This article reviews results of reports suggesting that venlafaxine extended release (XR) may play an important role in the treatment of anxiety disorders, particularly generalized anxiety disorder (GAD). Statistically significant improvements in GAD for venlafaxine XR compared with placebo on the basis of the Hamilton Rating Scale for Anxiety were seen in the acute treatment studies up to 8 weeks and were maintained for 6 months. One comparative study found venlafaxine XR to be as effective as, or on some measures more effective than, buspirone at relieving GAD. Venlafaxine XR was safe and well tolerated in the GAD studies, with discontinuation rates due to adverse effects similar to the rates seen with placebo or buspirone.

Abstract
Panic disorder is a prevalent psychiatric condition that often is chronic and rarely resolves without medical intervention. Many patients with panic disorder initially present with a variety of somatic symptoms, including chest pain, nausea, or dizziness, and patients frequently seek care in ambulatory care settings. Although panic disorder is classified as a single entity, it can have many dimensions and may be associated with significant morbidity. During the past 2 decades, there have been significant advances in the treatment of panic disorder, and a range of therapeutic choices is now available. Four classes of medications, including the selective serotonin reuptake inhibitors (SSRIs), high-potency benzodiazepines, tricyclic antidepressants, and monoamine oxidase inhibitors, may be considered for the management of patients with panic disorder. Emerging clinical data favor the SSRIs as first-line treatment for patients with panic disorder, and paroxetine and sertraline have been approved by the U.S. Food and Drug Administration for use in panic disorder. This article reviews the efficacy and safety of these treatments, as well as their relative merits and disadvantages, and assists the practicing clinician in choosing among the various pharmacotherapies to tailor therapy to each patient's individual needs.

Abstract
OBJECTIVE As the health care reimbursement system has changed, brief screens for detecting mental disorders in primary care have been developed. These efforts have faced the formidable task of identifying patients with mental disorders, while at the same time minimizing the number of misclassified cases. Here we consider the balance between sensitivity and positive predictive value. Primary care patients with false positive and false negative results on screens for depression and panic disorder are compared with regard to comorbidity and functional impairment. METHODS This was a cross-sectional psychometric study. The study sample included 1001 primary care patients from the Department of Internal Medicine at Kaiser Permanente in Oakland, California. The Symptom-Driven Diagnostic System for Primary Care (SDDS-PC) screens and Sheehan Disability Scale were completed by the subjects. The SDDS-PC diagnostic interviews were administered to all subjects. RESULTS Patients with false positive results on the panic disorder screen did not differ from patients with false negatives results with regard to rates of other psychiatric disorders, functional impairment, or mental health service utilization. In contrast, patients with false negative depression screen results had significantly more psychiatric disorders and functional impairment than those with false positive depression results. CONCLUSIONS A substantial number of patients with either false positive or false negative screen results met diagnostic criteria for other mental disorders. Given the nominal burden of follow-up assessments for patients with positive screens, these data suggest that erring on the side of sensitivity may have been preferable when algorithms for these screens were selected.

Abstract
The Mini-International Neuropsychiatric Interview (M.I.N.I.) is a short structured diagnostic interview, developed jointly by psychiatrists and clinicians in the United States and Europe, for DSM-IV and ICD-10 psychiatric disorders. With an administration time of approximately 15 minutes, it was designed to meet the need for a short but accurate structured psychiatric interview for multicenter clinical trials and epidemiology studies and to be used as a first step in outcome tracking in nonresearch clinical settings. The authors describe the development of the M.I.N.I. and its family of interviews: the M.I.N.I.-Screen, the M.I.N.I.-Plus, and the M.I.N.I.-Kid. They report on validation of the M.I.N.I. in relation to the Structured Clinical Interview for DSM-III-R, Patient Version, the Composite International Diagnostic Interview, and expert professional opinion, and they comment on potential applications for this interview.

Abstract
OBJECTIVE Several recent studies have documented that substantial functional impairment is associated with many of the mental disorders seen in primary care. However, brief measures of mental health-related functional impairment are not commonly applied in primary care settings. The Sheehan Disability Scale (SDS), a three-item instrument for assessing such impairment, is evaluated in this study. METHOD A psychometric analysis of the SDS was conducted with a sample of 1001 primary care patients at Kaiser Permanente In Oakland, California. The SDS and the Symptom Driven Diagnostic System for Primary Care assessments were completed. RESULTS The internal consistency reliability of the SDS is high, with coefficient alpha of 0.89. The construct validity was substantiated in two ways. A one-factor model fit the data quite well. Furthermore, patients with each of six psychiatric disorders had significantly higher impairment scores than those who did not. Finally, over 80 percent of the patients with mental disorder diagnoses had an elevated SDS score and nearly 50 percent of those with elevated SDS scores had at least one disorder. CONCLUSIONS The psychometric properties of the SDS were evaluated in primary care. The internal consistency reliability was high. The analyses also lend empirical support for the construct validity. The scale is a sensitive tool for identifying primary care patients with mental health-related functional impairment, who would warrant a diagnostically-oriented mental health assessment.

Abstract
This study was designed to develop and validate a new computerized version of the Symptom Driven Diagnostic System for Primary Care (SDDS-PC) and examine its feasibility in primary care practice. One thousand and one patients (ages 18-70) coming for routine care to Kaiser-Permanente were screened on a self-administered symptom scale for major depression, alcohol and drug dependence, generalized anxiety, panic and obsessive compulsive disorders, and suicidal behavior. The screen was followed up by a brief diagnostic interview, administered by a nurse, which yielded a one-page summary of positive symptoms and a provisional computer-generated diagnosis for the physician. The physician reviewed the summary results and made a diagnosis. The nurse and physician were blind to the screen results. Patients were reinterviewed within 96 hours by a mental health professional (MHP) blind to previous results. The nurses' interviews ranged between 1.5 and 3.5 minutes for a screened positive diagnosis. Agreement between the nurse and physician diagnoses was excellent to moderate. Disagreement was usually in the direction of the physician ruling out major mental disorders in favor of subsyndromal or medical explanations. Only rarely did physicians diagnose disorders not detected by the nurse interview. Agreement between physician and MHP was moderate. Physicians using the SDDS-PC seldom made diagnoses that were not confirmed by the independent assessment of the MHP. The SDDS-PC may facilitate recognition of psychiatric disorders and minimize the physician's time in information gathering.

Abstract
OBJECTIVE This article examines social and occupational disability associated with several DSM-IV mental disorders in a group of adult primary care outpatients. METHOD The subjects were 1,001 primary care patients (aged 18-70 years) in a large health maintenance organization. Data on each patient's sociodemographic characteristics and functional disability, including scores on the Sheehan Disability Scale, were collected at the time of a medical visit. A structured diagnostic interview for current DSM-IV disorders was then completed by a mental health professional over the telephone within 4 days of the visit. RESULTS The most prevalent disorders were phobias (7.7%), major depressive disorder (7.3%), alcohol use disorders (5.2%), generalized anxiety disorder (3.7%), and panic disorder (3.0%). A total of 8.3% of the patients met the criteria for more than one mental disorder. The proportion of patients with co-occurring mental disorders varied by index disorder from 50.0% (alcohol use disorder) to 89.2% (generalized anxiety disorder). Compared with patients who had a single mental disorder, patients with co-occurring disorders reported significantly more disability in social and occupational functioning. After adjustment for other mental disorders and demographic and general health factors, compared with patients with no mental disorder, only patients with major depressive disorder, bipolar disorder, phobias, and substance use disorders had significantly increased disability, as measured by the Sheehan Disability Scale. CONCLUSIONS Primary care patients with more than one mental disorder are common and highly disabled. Individual mental disorders have distinct patterns of psychiatric comorbidity and disability.

Abstract
OBJECTIVE The goal of this study was to characterize primary care patients with false positive results on screens for mental disorders. METHOD A sample of 1,001 primary care patients completed self-administered screens and structured interviews for DSM-IV diagnoses. RESULTS A substantial proportion of the patients with false positive screen results for at least one diagnosis met the diagnostic criteria for other psychiatric disorders. They also had significantly greater functional impairment and higher rates of recent use of mental health services than the subjects with true negative results on the screens. CONCLUSIONS Although the positive predictive values of screens for specific mental disorders are in line with those of other medical screens, false positive results are not uncommon. This may be due in part to the sensitivity of brief screening instruments to nonspecific symptoms. The results suggest that as with other screens used in primary care, patients with false positive results on screens for mental disorders should receive clinical attention.

Abstract
BACKGROUND Psychotic symptoms include a variety of disturbances in perception, reality testing, speech, and behavior. We examine the prevalence, distribution, treatment, and functional impairment associated with psychotic symptoms in primary care patients. METHODS Data are drawn from a recent study of adult primary care patients (N = 1001) in a large, urban, prepaid group practice. At the medical visit, patients completed a questionnaire that probed demographic characteristics, health status, and mental health care utilization. Following the visit, patients received a telephone-administered, structured psychiatric interview that included 11 psychotic symptoms. Medication prescription data were also available. Comparisons are presented of patients with and without psychotic symptoms. RESULTS Thirty-seven (3.7%) patients reported one or more psychotic symptoms, most commonly a belief that others were spying on or following them (n = 16). As compared with patients without psychotic symptoms, a larger proportion of the patients with psychotic symptoms reported mental health-related work loss (54.1% vs 17.9%, P < .0001), suicidal ideation (21.6% vs 2.6%, P < .0001), major depressive disorder (32.4% vs 6.3%, P < .0001), bipolar disorder (29.7% vs 1.2%, P < .0001), and several other mental disorders. An antipsychotic medication had been prescribed during the previous 17 to 20 months for only two (5.4%) of the patients with psychotic symptoms. CONCLUSIONS Psychotic symptoms were relatively common (3.7%) in this practice and were strongly associated with functional impairment and affective, anxiety, or substance use disorders. Primary care physicians are encouraged to examine patients with these mental disorders for the presence of psychotic symptoms.

Abstract
OBJECTIVE To describe the prevalence and clinical characteristics of primary care patients who report suicidal ideation during the month before their medical visit. DESIGN Analysis of a self-administered suicidal ideation screening item using sociodemographic data, treatment history, and clinical data from structured interviews. SETTING Three Rhode Island private family practices, a South Carolina family medicine residency, and a California prepaid internal medicine group practice. PATIENTS Adult primary care patients (N = 2,749), 18 to 70 years old, who are able to read and write English, able to complete study forms, and willing to provide informed consent. RESULTS Sixty-seven (2.44%) of the patients reported suicidal ideation ("feeling suicidal") during the past month, and most of those patients (58.2%) received no mental health care during that time. The adjusted risk of suicidal ideation was significantly elevated for patients with self-reported fair or poor physical health (odds ratio [OR] 2.5; 95% confidence interval [CI] 1.5, 4.1), fair to poor emotional health (OR 18.0; 95% CI 8.8, 37.0), marital distress (OR 4.4; 95% CI 2.2, 8.8), and recent mental health-related work loss (OR 6.3; 95% CI 3.7, 10.5). In the California sample, patients with major depression (R 31.2; 95% CI 12.8, 76.1). generalized anxiety disorder (OR 23.4; 95% CI 8.1, 67.1), and drug abuse or dependence (OR 9.6; 95% CI 2.9, 31.6) were at increased risk of suicidal ideation. The "feeling suicidal" item identified 10 of 12 patients who acknowledged a recent plan to kill themselves. CONCLUSIONS In these primary care patients, suicidal ideation is strongly associated with mental disorder and mental health-related functional impairment, and can be detected with a single self-report "feeling suicidal" item.

Abstract
The frequent occurrence of desynchrony between psychiatric symptoms and disability makes it necessary to measure disability/ functional impairment in addition to psychiatric symptoms when tracking treatment outcome. Existing disability measures in psychiatry are comprehensive but lengthy. There is a need for short, simple, cost-effective, sensitive measures of disability and functional impairment in psychiatric disorders. We developed a discretized analog disability scale (DISS) which uses visual-spatial, numeric and verbal descriptive anchors to assess disability across three domains: work, social life and family life. The DISS has proved to be very sensitive to change in drug treatment studies in psychiatry. The usefulness of the DISS in assessing disability in terms of work, social and family relationships is discussed.

Abstract
This article reviews all available studies reported in the literature or presented at national or international meetings on the efficacy of serotonin selective reuptake inhibitors and less selective serotonin uptake inhibitors in panic disorder. The research data lags behind-rather than leads-experience in everyday clinical practice. The emerging data suggest that serotonin uptake inhibitors are superior to placebo and better tolerated than most of the older alternatives. As a result they are now becoming first-choice treatments in panic disorder.

Abstract
The role of serotonin in psychiatry has been the focus of speculation for several decades. The literature since 1966 is reviewed (and referenced) and five organizing questions are identified: (1) What are the major hypotheses regarding the involvement of the serotonin system in panic disorder? (2) Is there a serotonin system defect associated with panic disorder? (3) Is a serotonin system defect the cause of panic disorder? (4) Are the 5-HT1A agonists and the 5-HT2 antagonists effective in this condition? (5) Are serotonin selective uptake inhibitors (SSUIs) effective in panic disorder via the serotonin system or some other mechanism? Though the role of the serotonin system in panic disorder and social phobia is uncertain there is increasing agreement that SSUIs effectively treat panic disorder but further double-blind placebo-controlled studies are needed.

Abstract
This 8-week double-blind placebo-controlled trial investigated the relative efficacy and safety of alprazolam and buspirone in the treatment of panic disorder. Alprazolam (mean +/- SD dose 5.2 +/- 2.6 mg) produced a rapid and sustained improvement in panic attacks, anxiety, phobias, and disability and was superior to buspirone (mean +/- SD dose 61 +/- 26.5 mg) and placebo on all of these measures on completer (n = 85) and endpoint analysis (n = 92). Although higher doses of buspirone were used in this study than in previous trials, buspirone was not superior to placebo on any of the outcome measures. The results were disappointing in light of buspirone's benign side effect profile and low abuse potential.

Abstract
OBJECTIVE This study compares substance use by medical specialty among resident physicians. METHOD The authors estimated the prevalence of substance use of 11 medical specialties from a national sample of 1,754 U.S. resident physicians. RESULTS Emergency medicine and psychiatry residents showed higher rates of substance use than residents in other specialties. Emergency medicine residents reported more current use of cocaine and marijuana, and psychiatry residents reported more current use of benzodiazepines and marijuana. Contrary to recent concerns, anesthesiology residents did not have high rates of substance use. Family/general practice, internal medicine, and obstetrics/gynecology were not among the higher or lower use groups for most substances. Surgeons had lower rates of substance use except for alcohol. Pediatric and pathology residents were least likely to be substance users. CONCLUSIONS The authors' previous research indicates that residents overall have lower rates of substance use than their age peers in society. Yet resident substance use patterns do differ by specialty. Residents in some specialties are more likely to use specific classes of drugs, to use a greater number of drug classes, and to be daily users of alcohol or cigarettes.

Abstract
OBJECTIVE To estimate the prevalence of substance use among US physicians. DESIGN A mailed, anonymous, self-report survey that assessed use of 13 substances and permitted comparison with results of the National Household Survey on Drug Abuse. Rates of physician substance use were weighted to provide national prevalence estimates. PARTICIPANTS A national sample of 9600 physicians, stratified by specialty and career stage, and randomly selected from the American Medical Association master file. The response rate after three mailings was 59%. Demographic characteristics of respondents closely reflected those of the US physician population. MAIN OUTCOME MEASURES Subjects' self-reported use of 13 substances in their lifetime, the past year, and the past month; reasons for use; self-admitted substance abuse or dependence; and whether treatment was received. For controlled prescription substances, respondents were asked to report only use "not prescribed by another physician for a legitimate medical or psychiatric condition." RESULTS Physicians were less likely to have used cigarettes and illicit substances, such as marijuana, cocaine, and heroin, in the past year than their age and gender counterparts in the National Household Survey on Drug Abuse. They were more likely to have used alcohol and two types of prescription medications--minor opiates and benzodiazepine tranquilizers. Prescription substances were used primarily for self-treatment, whereas illicit substances and alcohol were used primarily for recreation. Current daily use of illicit or controlled substances was rare. CONCLUSIONS Although physicians were as likely to have experimented with illicit substances in their lifetime as their age and gender peers in society, they were far less likely to be current users of illicit substances. The higher prevalence of alcohol use among respondents may be more a characteristic of their socioeconomic class than of their profession. A unique concern for physicians, however, is their high rate of self-treatment with controlled medications--a practice that could increase their risk of drug abuse or dependence. Uniform national guidelines are needed to sensitize medical students and physicians to the dangers of self-treatment with controlled prescription substances.

Abstract
This study examined the relationship between work-related stress and substance use among resident physicians in the United States. Unlike previous studies of physician stress, this study distinguished between "stressors" (stressful job conditions) and "strains" (reactions to the work environment) and correlated each of these with substance use. Results indicated that relations among stressors, strains, and substance use were not strong. Strains, however, were more strongly related to substance use than stressors. Additionally, benzodiazepines were more strongly related to strains than other substances, suggesting that they may be used for self-treatment. Other implications of these findings and future research needs are discussed.
