fibrodysplasia ossificans progressiva (fop, mim 135100) is a rare genetic disease that is often inherited sporadically in an autosomal dominant pattern. the disease manifests in early life with malformed great toes and, its episodic and progressive bone formation in skeletal muscle after trauma is led to extra-articular ankylosis. in this study, a 17 year-old affected girl born to a father with...

background: sulfur mustard is one of the chemical warfare gases that has been known as a vesicant or blistering agents. it is a chemical alkylating compound agent that can be frequently absorbed through skin, respiratory system, genital tract, and ocular system. this study was done to pathologically analyze the microscopic pancreatic lesions in cadavers. methods: this case series study was perf...

Some studies have already addressed the effects of occupational organic solvent exposure on the visually evoked potentials (VEPs). Visual system is an important target for Sulphur Mustard (SM) toxicity. A number of Iranian victims of Sulphur Mustard (SM) agent were apprehensive about the delay effect of SM on their vision and a possible delay effect of SM on their visual cortex. This investigat...

Among the blistering (vesicant) chemical warfare agents (CWA), sulfur mustard is the most important since it is known as the “King of chemical warfare agents”. The use of sulfur mustard has caused serious damages in several organs, especially the eyes, skin, respiratory, central and peripheral nervous systems after short and long term exposure, incapacitating and even killing people and troops....

Background: Basal cell carcinoma (BCC), the most common form of skin cancer, usually occurs in the sun-exposed areas of the body like head and neck, yet is also seen in unexpected sites. Myriad studies have mentioned a lower limb BCC incidence rate of 1.5-13.5%.Methods: The present retrospective cross-sectional study was conducted on 650 BCC patients, who were referred to the dermatology tumor ...

It is unlikely that Gulf War veterans are suffering chronic effects from illnesses caused by chemical warfare nerve agent exposure. Extensive investigation and review by several expert panels have determined that no evidence exists that chemical warfare nerve agents were used during the Gulf War. At no time before, during, or after the war was there confirmation of symptoms among anyone, milita...

AIMS To study the synergistic effect of occupational chemical exposure and hepatitis virus infection on serum aminotransferase activity. METHODS A total of 568 male workers who were employed in five polyvinyl chloride (PVC) or four vinyl chloride monomer (VCM) manufacturing factories were studied. Information relating to current job title, alcohol consumption, and cigarette smoking was obtain...

background: the goal of the present study was to report the results of two parallel works in which the incidence of fetal deaths and also congenital malformations among the progenies of the iranian chemical victims were studied. methods: the subjects were progenies of a randomly selected population from survivors of chemical attacks during iran-iraq conflict. totally 807 male cases ranged 18-85...

Food may be contaminated with many chemical substances at any level along the production chain. Chemicals that may be found in food items can simultaneously be present in other matrices, as air, water, soil and dust; therefore, human exposure to chemicals via food has to be summed to the exposure through all the other possible routes. The role played by the food production chain with regard to ...
