We tested the hypothesis that exposure to a stimulus resembling the original traumatic event would induce naloxone-reversible analgesia in patients with posttraumatic stress disorder (PTSD). Eight medication-free Vietnam veterans with PTSD and eight veterans without PTSD, matched for age and combat severity, viewed a 15-minute videotape of dramatized combat(More)
Chronic post traumatic stress has been described as a "physioneurosis" (Kardiner 1941), that is, a mental disorder with both psychological and physiological components. The behavioral sequelae of inescapable shock in animals and of massive psychic trauma in people show a striking parallel. Inescapable shock in animals leads to both transient catecholamine(More)
The hypothesis that the animal model of inescapable shock (IES) is an appropriate model for posttraumatic stress disorder (PTSD) predicts that re-exposure to a traumatic stressor will precipitate opioid-mediated stress-induced analgesia in people with PTSD. Eight Vietnam veterans with PTSD and eight matched veterans without PTSD viewed a combat videotape(More)
Beck's cognitive model predicts that depressed and anxious individuals can be differentiated on the basis of their cognitions regarding their self, world, and future. The present experiment used a trait-rating and incidental recall paradigm to test this "content-specificity" hypothesis. Clinically depressed, anxious, and psychiatric control subjects were(More)
ABSTRACT Adult patients with significant childhood and current symptoms of attention-deficit hyperactivity disorder (ADHD), but whose ADHD had not been previously recognized, were evaluated by three clinical consultants working with diverse referral populations. These 60 adults shared common characteristics of physical and mental restlessness, impulsivity,(More)
The CXCR4 chemokine receptor has been shown to respond to the C-X-C chemokine stromal-derived factor (SDF-1) and has recently been shown to be an important coreceptor for HIV-1 infection. In the present paper we have tested a number of human lymphocyte cell lines, including Jurkat, HUT78, CEM, and Sup-T1 for the presence of CXCR4 receptors. We found that(More)
The prevalence of homozygous hereditary hemochromatosis (HHC) is estimated at 1:250 in Caucasian adults. Little is known about ethnic subpopulations that might be at increased risk for this disease. HLA data have suggested a Celtic origin for HHC. Screening for HHC was offered to all employees of the Massachusetts Polaroid Corporation. Participants with a(More)
Infections due to Salmonella serotype enteritidis have increased markedly in the northeastern United States. Due to the potential severity of these infections, host risk factors for infection were determined in the largest nosocomial S. enteritidis outbreak to have occurred in the United States. In a case-control study, patients in a New York City hospital(More)
