In the field of traumatic stress, chemoprophylaxis is a term that is often used but rarely well understood. There has been no shortage of debate on the issue, but few rigorous studies to ground the discussion. The purpose of the current paper is to explore the issues surrounding this contentious area. Databases including PubMed, PsychArticles and Web of Knowledge were searched using the key words 'chemo or pharmaco', 'prevention or prophylaxis', and 'PTSD or post-traumatic stress'.

The objective of this study was to determine whether perceived health status of Iraqi immigrants and refugees residing in the United States was related to pre-migration environmental stress, current unemployment, and if they had emigrated before or after the 1991 Gulf War. A random sample of Iraqis residing in Southeast Michigan, US, was interviewed using an Arab language structured survey. The main outcome measure was self-rated health (SRH). Major predictors included socioeconomics, employment status, pre-migration environmental stress, and health disorders.

Few studies have examined the experience of posttraumatic growth, among police officers following traumatic incidents. Additionally, research examining the relationship between posttraumatic distress (e.g., posttraumatic symptoms) and posttraumatic growth among various populations has been inconsistent.

This article explicates a theory that oxytocin, a sexually dimorphic neurotransmitter and paracrine hormone, is a plausible mechanism linking early relational trauma with posttraumatic self disorders (e.g., dissociation, somatization, and interpersonal sensitivity), posttraumatic stress disorder, and pelvic visceral dysregulation disorders (e.g., irritable bowel syndrome, chronic pelvic pain, interstitial cystitis, and hyperemesis gravidarum). This posttraumatic oxytocin dysregulation disorders theory is consistent with the historical and contemporary literature.
