Dose-dependent emergence of acute and recurrent corneal lesions in sulfur mustard-exposed rabbit eyes.

Sulfur mustard (SM) is a lipid soluble alkylating agent that causes genotoxic injury. The eye is highly sensitive to SM toxicity and exposures exceeding 400 mg min/m can elicit irreversible corneal pathophysiologies. Development of medical countermeasures for ocular SM exposure has been hindered by a limited understanding of dose-dependent effects of SM on corneal injury.

Attached to a Diagnosis: The Quandary of Social Deficits and Reactive Attachment Disorder.

Alex is a 9-year-old boy brought to you, his primary care provider, for a "fifth opinion." You have cared for Alex since he was adopted from a Romanian orphanage at 3 years of age. He has been physically healthy with normal growth parameters and no evidence of fetal alcohol syndrome.

Median lethal dose determination for percutaneous exposure to soman and VX in guinea pigs and the effectiveness of decontamination with M291 SDK or SANDIA foam.

Soman (GD) and VX are chemical warfare agents that can be absorbed through the skin. We determined the median lethal dose (MLD) for the cutaneous application of GD and VX in anesthetized haired guinea pigs and then tested the ability of a currently fielded decontamination kit, the M291 Skin Decontamination Kit (SDK), and decontaminating foam made by SANDIA Labs to decontaminate areas that have been exposed to cutaneous applications of GD and VX. The fur of guinea pigs was clipped on the left flank 24h prior to exposure.

Perspectives on the use of scopolamine as an adjunct treatment to enhance survival following organophosphorus nerve agent poisoning.

Scopolamine (SCP) is an anticholinergic drug used clinically for decades to treat motion sickness, as a surgical preanesthetic, and as a smooth muscle antispasmodic. It has also been used experimentally as a pretreatment and/or treatment adjunct to mitigate the toxic sequelae of organophosphorus (OP) nerve agent intoxication. SCP has been reported to increase survival, prevent or terminate seizures, and reduce morbidity from nerve agent intoxication in a number of animal models.

Butyrylcholinesterase as a therapeutic drug for protection against percutaneous VX.

The administration of purified human plasma-derived butyrylcholinesterase (HuBuChE) as a pretreatment has been demonstrated to enhance survival and protect against decreased cognitive function after exposure to organophosphorus poisons (OPs). Based on efficacy data obtained with guinea pigs and non-human primates and the lack of behavioral side effects, plasma-derived HuBuChE has been granted investigational new drug status by the US Food and Drug Administration. The recent availability of a recombinant form of HuBuChE (rHuBuChE) from the milk of transgenic goats has now allowed us to determine the pharmacokinetics of that material in guinea pigs and use it as a therapy following exposure to the VX.

Pro-2-PAM therapy for central and peripheral cholinesterases.

Novel therapeutics to overcome the toxic effects of organophosphorus (OP) chemical agents are needed due to the documented use of OPs in warfare (e.g. 1980-1988 Iran/Iraq war) and terrorism (e.

Education and counselling for genital herpes: perspectives from patients.

The incidence and prevalence of genital herpes continue to increase in the USA, and the availability of new, accurate serological tests for herpes simplex virus (HSV) may identify millions of previously unrecognized cases. Newly diagnosed genital HSV infections place a serious burden on healthcare providers in terms of education and counselling. The study was initiated to assess the need for and potential use of an improved system for education and counselling of patients newly diagnosed with genital herpes.

Application and detection of (14)c-hd in two mouse models.

The CD1-haired mouse and the SKH-hairless mouse are two animal models that have been used to evaluate sulfur mustard (HD) exposure and protection in our laboratory. In a recent study we observed that a substance P inhibitor protected the haired mouse ear against an HD solution, but the same drug was not successful in protecting the hairless mouse against HD vapor. This experiment prompted us to compare HD exposures between these models.
