In October 2001, four cases of inhalational anthrax occurred in workers in a Washington, D.C., mail facility that processed envelopes containing Bacillus anthracis spores. We reviewed the envelopes’ paths and obtained exposure histories and nasal swab cultures from postal workers. Environmental sampling was performed. A sample of employees was assessed for antibody concentrations to B. anthracis protective antigen. Case-patients worked on nonoverlapping shifts throughout the facility. Environmental sampling showed diffuse contamination of the facility, suggesting multiple aerosolization events. Potential workplace exposures were similar for the case-patients and the sample of workers. All nasal swab cultures and serum antibody tests were negative. Available tools could not identify subgroups of employees at higher risk for exposure or disease. Prophylaxis was necessary for all employees. To protect postal workers against bioterrorism, measures to reduce the risk of occupational exposure are necessary.

The purpose of this study was to compare certain demographic, clinical, and criminal variables within subgroups of obsessional followers, and compare them to a group of offenders with mental disorders to attempt to replicate earlier findings. A static group archival design utilized a non-random group of convenience and a randomly selected comparison group. Sixty-five obsessional followers and 65 offenders with mental disorders were evaluated by psychiatrists and psychologists for court ordered reasons during their criminal proceedings. Both groups were evaluated during the same period, in the same court diagnostic clinic, and generally for sentencing determinations. The obsessional followers were measured on demographic, diagnostic, pursuit, victim, threat, violence, emotional, motivational, and defense variables. Inferential comparisons that used parametric and nonparametric statistics were done within and between groups on select variables. The obsessional followers had significantly greater estimated IQ than the offenders with mental disorders, but were neither older nor better educated. There were no significant differences in the high prevalence of both DSM-IV Axis I and II diagnoses. Obsessional followers who stalked prior sexual intimates were significantly more likely to have a substance abuse or dependence diagnosis. Obsessional followers who stalked strangers or acquaintances were more likely to be delusional. The majority of the obsessional followers, primarily motivated by anger, both threatened and were violent toward person or property. The modal obsessional follower is an average or above IQ, unemployed, unmarried male in his fourth decade of life, chronically pursuing a prior sexually intimate female. He is diagnosed with substance abuse or dependence and a personality disorder NOS, and has a prior psychiatric, criminal, and substance abuse history. He is angry, likely to threaten her, and assault her person or property without causing serious injury.

Behavioral and familial correlates of predominantly White, suburban heroin abusers were investigated to determine whether such abuse was self-contained experimentation or suggestive of generalized personality disorders and impaired family relationships. Twenty of 296 male high school students recruited from 10 middle-class suburban schools had engaged in episodic heroin abuse. Of 29 antisocial behaviors other than heroin abuse assessed, heroin abusers engaged in 16 significantly more frequently. Heroin abusers found their fathers to be significantly less nice, honest, strong, and kind than did nonabusers, according to semantic differential technique. They found themselves to be significantly less strong than did nonabusers, suggesting failure to model themselves after adequately coping fathers. Heroin abusers also found their mothers to be significantly less fair, honest, and valuable than did nonabusers. It was concluded that episodic heroin abuse among suburban adolescents is suggestive both of generalized antisocial behavior and of impaired family relationships.
