Abstract
A substantial minority of deployed Gulf War veterans developed posttraumatic stress disorder (PTSD), depression, and several chronic illnesses. Although military combat and exposure to certain nuclear, biological, and chemical agents (NBCs) increase risk for post-deployment health problems, they do not fully explain many Gulf War veteran health diagnoses and are not viable treatment targets. Experiential avoidance (EA; one's unwillingness to remain in contact with unpleasant internal experiences) is a modifiable psychosocial risk factor associated with PTSD and depression in veterans as well as pain and gastrointestinal diseases in the general population. In this study, we recruited a national sample of deployed Gulf War veterans (N = 454) to test the hypothesis that greater EA would be significantly associated with higher lifetime odds of PTSD, depression, "Gulf War Illness" (GWI/CMI), and other chronic illnesses common in this veteran cohort. Participants completed a self-report battery assessing demographic, military-related, and health-related information. Multivariate analyses showed that after adjusting for age, sex, race, combat exposure, and NBC exposure, worse EA was associated with higher lifetime odds of PTSD, depression GWI/CMI, gastrointestinal problems, irritable bowel syndrome, arthritis, fibromyalgia, and chronic fatigue syndrome (ORs ranged 1.25 to 2.89; effect sizes ranged small to large), but not asthma or chronic obstructive pulmonary disease. Our findings suggest medical and mental health providers alike should assess for EA and potentially target EA as part of a comprehensive, biopsychosocial approach to improving Gulf War veterans' health and wellbeing. Study limitations and future research directions are also discussed.

Abstract
Up to June 2001, 3000 British veterans of the Gulf War had sought advice from a special medical assessment programme established because of an alleged Gulf War syndrome. After assessment those attending were classified as completely well, well with symptoms, well with incidental diagnoses treated or controlled, or unwell (physically or mentally). Mental illness was confirmed by a psychiatrist. The first 2000 attenders have been reported previously. The present paper summarizes findings in all 3000. 2252 (75%) of those attending were judged ‘well’, of whom 303 were symptom-free. Medical diagnoses were those to be expected in such an age-group (mean age 34 years, range 21–63). No novel or unusual condition was found. In 604 of the 748 unwell veterans, a substantial element of the illness was psychiatric, the most common condition being post-traumatic stress disorder. The healthcare requirements of the Gulf veterans seen in this programme can therefore be met by standard National Health Service provision.

Abstract
Depleted uranium munitions have been used in recent military operations in both the Gulf and the Balkans and there have been concerns that exposure to depleted uranium may be a cause of `Gulf War Syndrome’ and cancer clusters. We recount the properties of depleted uranium, its military uses, and the situations in which personnel may be exposed. Following a review of scientific literature, the health effects of depleted and natural uranium exposure are described and the major outcomes of research into Gulf Veterans’ Illnesses are summarised. We conclude that, although there is the potential for uranium exposures to cause renal damage or lung cancer, the risk of harm following depleted uranium exposure in military settings seems to be low. We advise on the management of casualties exposed to depleted uranium and suggest control measures that may be appropriate to protect personnel who provide casualty care.

Abstract
Using the strength-of-conclusion scheme enumerated in Box 2, based on two class II studies, there is probably a causal link between deployment to the Persian Gulf theater of operation and the development of the poorly defined multisymptom illness known as GWS (level B). Based on class IV studies, there is insufficient evidence to determine if exposure to toxins encountered during the Persian Gulf war caused GWS (level U). A major limitation of the literature regarding the GWS is the reliance on self-reporting to measure exposure to putative causal toxins. Although objective measures of toxin exposure in GWV generally is unavailable, modeling techniques to estimate exposure levels to low-level nerve agents and smoke from oil well fires have been developed. It would be useful to determine if exposure levels determined by these techniques are associated with GWS. The lack of a clear case definition GWS also hampers research. Some go even further, claiming that the absence of such a definition renders the condition illegitimate. Although an objective marker to GWS would be useful for studies, the absence of such a marker does not make the syndrome any less legitimate. in essence, GWS merely is a convenient descriptive term that describes a phenomenon: GWV reporting suffering from medically unexplained health-related symptoms. In this sense, it shares much with the other medically unexplained syndromes encountered in practice. The real debate surrounding medically unexplained conditions is not whether or not they exist, but defining their cause. In this regard, investigators fall into two camps. One camp insists that the conditions are caused by a yet-to-be-discovered medical problem, rejecting out of hand the possibility of a psychologic origin. The other camp insists the conditions are fundamentally psychogenic rejecting the possibility of an undiscovered medical condition. The evidence shows, however, that the conditions exists, the suffering is real, and the causes are unknown.

Abstract
The authors have reviewed the literature on neurobehavioral toxicity of pesticides to assess the status of knowledge on this matter. Some data suggest that exposure to DDT and fumigants may be associated with permanent decline in neurobehavioral functioning and increase in psychiatric symptoms, but, due to the limited number of studies available and the scarce knowledge on exposure levels, no firm conclusion can be drawn. Data on subjects acutely poisoned with organophosphorous compounds suggest that an impairment in neurobehavioral performance and, in some cases, emotional status may be observed as a long-term sequela, but the possibility still remains that these effects were only an aspecific expression of damage and not of direct neurotoxicity. Studies carried out on subjects chronically exposed to organophosphates, but never acutely poisoned, do not provide univocal results but the slight changes consistently observed in sheep dippers suggest the need of focusing on activities characterized by relatively higher exposure levels. In general, the main limits of existing knowledge are the variability of the testing methods used, which makes it difficult to compare the results of single studies, and the scarce knowledge on exposure levels. A promising approach may be the conduction of prospective longitudinal or cohort studies, where exposure and dose assessment can be more easily controlled, or the evaluation of cohorts of workers a priori selected for the availability of environmental and biological monitoring data. The follow up of the populations under study may give an answer at the problem of the prognostic significance of the observed changes. Also the protocols used to assess neurobehavioral functioning need to be standardized.
