The role of the sand in chemical warfare agent exposure among Persian Gulf War veterans: Al Eskan disease and "dirty dust".

The purpose of this paper is to inquire into the relationship between Al Eskan disease and the probable exposure to chemical warfare agents by Persian Gulf War veterans. Al Eskan disease, first reported in 1991, compromises the body's immunological defense and is a result of the pathogenic properties of the extremely fine, dusty sand located in the central and eastern region of the Arabian peninsula. The disease manifests with localized expression of multisystem disorder. Signs and symptoms of Al Eskan disease have been termed by the news media "Persian Gulf syndrome." The dust becomes a warfare agent when toxic chemicals are microimpregnated into inert particles. The "dirty dust" concept, that the toxicity of an agent could be enhanced by absorption into inactive particles, dates from World War I. A growing body of evidence shows that coalition forces have encountered Iraqi chemical warfare in the theater of operation/Persian Gulf War to a much greater extent than early U.S. Department of Defense information had indicated. Veterans of that war were exposed to chemical warfare agents in the form of direct (deliberate) attacks by chemical weapons, such as missiles and mines, and indirect (accidental) contamination from demolished munition production plants and storage areas, or otherwise. We conclude that the microimpregnated sand particles in the theater of operation/Persian Gulf War depleted the immune system and simultaneously acted as vehicles for low-intensity exposure to chemical warfare agents and had a modifying-intensifying effect on the toxicity of exposed individuals. We recommend recognition of a new term, "dirty sand," as a subcategory of dirty dust/dusty chemical warfare agents. Our ongoing research efforts to investigate the health impact of chemical warfare agent exposure among Persian Gulf War veterans suggest that Al Eskan disease is a plausible and preeminent explanation for the preponderance of Persian Gulf War illnesses.

Al Eskan disease: Persian Gulf syndrome.

This article examines the potential relationship between Al Eskan disease and the Persian Gulf syndrome. Al Eskan disease, reported in Military Medicine in 1992, is a novel and previously unreported condition triggered by the exceptionally fine sand dust of the Central and Eastern Saudi Arabian peninsula. We repeat our study of the pathogenesis of Al Eskan disease to include the ultrastructural and microanalytical study of the sand, aerobiological studies of the Kingdom of Saudi Arabia, and the etiology, symptoms, and prevalence of the disease. We conclude that immunodepression resulting from the continued presence of sand particles less than 1 micron in diameter in the lungs and bodies of Persian Gulf veterans explains not only the symptoms of the hyperegic lung condition of phase I and the symptoms of phase II of Al Eskan disease, but also provides an important clue to a common factor in most cases of Persian Gulf illnesses. We include a discussion of most of the commonly suspected agents in the Persian Gulf syndrome. In this case, we conclude that each of these factors, such as oil well fires, old-world diseases, or depleted uranium, are probably adjuvant or contributing causes. The only common exposure that would lead to recognition of the Persian Gulf syndrome as a single medical condition, rather than a catch-all phrase for unrelated conditions, appears to be exposure to the ubiquitous, fine sand of the area, and a resulting immunosuppression that is aggravated by opportunistic infections and other nonmicrobial ailments.

Report on the Hungarian Military Health Service Support (a former Soviet dominion).

The author describes the structure and organization of the Health Service Support of the Hungarian Armed Forces. The differences and similarities between the U.S. and the Hungarian Military Medical Services are highlighted. The potential for inter-operability is examined. The importance of such considerations is marked by the ongoing hostilities in the former Yugoslav Republic.

Al Eskan disease: Desert Storm pneumonitis.

The authors observed an acute desert-related disease when the mixture of the fine Saudi sand dust and pigeon droppings triggered a hyperergic lung condition. It was further aggravated by various kinds of organic pathogenic components contributing to an opportunistic infection of the lung. These all lead to the recognition of a new clinicopathological entity, Desert Storm pneumonitis or Al Eskan disease. For the first time, the Saudi sand dust's elemental composition was studied by ultrastructural and microanalytical means. The authors concluded that, contrary to previous beliefs, sand particles less than 1 microns (0.1 microns to 0.25 microns) in diameter are present in substantial quantities in the Saudi sand and are pathogenic, causing hyperergia. Pathogenesis of the sand dust, induced hyperergia, and its immunopathologic background are highlighted.

Graduate medical education into the 1990's. A call for debate.

The authors have reviewed the present system of graduate medical education, including independent, affiliated, and integrated residency training programs. Advantages and disadvantages are considered in light of recent changes in health-care delivery systems. Structure, historical development, present status, and limitations of the programs are discussed. Personnel resources of the residency program are classified as United States citizens and non-citizens, American medical school graduates, United States citizen graduates of foreign medical schools, and alien foreign medical school graduates, and their different educational backgrounds are compared. Financial aspects of these programs are considered, and the need to increase university control over residency programs, especially in multi-institutional affiliated residency training programs is discussed. The authors recommend upgrading the status of residents from that of student to that of full-fledged medical doctor with concomitant authority and responsibility.

Physical injuries, contractures and rigidity of skeletal muscle.

The authors condensed their knowledge of physical injuries of skeletal muscle, particularly injuries caused by mechanical energy, atmospheric pressure, radiation, extremes of temperature and electricity. The possible perils, outcomes and consequences are discussed. Special attention is given to the military medical projections.
