Alternative Specimens – Drug Testing

Drug use in the workplace continues to be a problem in the United States, as large numbers of illegal drug users pose a danger to themselves and others. The most common technique for detecting drug use in the workplace is urine drug testing. Problems with this technique include the lack of long-term drug detection and the inability to correlate test results with impairment. Other specimens for drug testing include saliva, hair, and sweat.

The Financial Review is subdivided into a Usual, Customary and Reasonable (UCR) Analysis and a Medical Billing Audit, and involves a comprehensive review of the Universal Bill and itemization. The Clinical Review is a thorough review of the medical records performed by trained Registered Nurses and the Medical Director to determine the necessity of treatment for accident-related injuries.

Organic Solvent-induced Neurotoxicity

Organic solvents are a chemical class of compounds that are used routinely in commercial industries. These compounds exist in liquid form at room temperature, and are useful because they can dissolve fats, oils, resins, rubbers, and plastics. Short-term, high level exposure to these compounds can result in reversible and irreversible health effects. Studies have demonstrated that some effects can persist for months to years after employees are removed from the area with solvent exposure.

Indoor Air Quality

Indoor air quality is most often compromised by mold, but can also be affected by off-gassing exposure, volatile organic compounds, and CO, NO2, and SO2 contamination. Three negative health effects that can result from exposure to certain molds are allergy, infection, and toxicity. Most effects from mold exposure disappear when the exposure decreases.

Spinal Cord Stimulators

Spinal Cord Stimulators use electrical currents to treat chronic pain. A small pulse generator, which is implanted in the abdomen, sends electrical pulses to the spinal cord. These electrical impulses interfere with the transmission of pain signals to the brain and theoretically lead to pain relief. Spinal Cord Stimulators are not considered as a treatment option until non-invasive treatments have failed.

Intrathecal Infusion Pumps

An Intrathecal Infusion Pump is an implantable drug delivery device that can administer a variety of medications (such as opioids, local anaesthetics, adrenergic-agonists, and other agents) through a catheter to the spine. These devices are invasive and costly, with granulomas potential side effects. Common side effects include migration of the catheter, infections, and side effects related to extensive opiate use.

Complex Regional Pain Syndrome

Complex Regional Pain Syndrome (CRPS) is a chronic pain syndrome characterized by continuous pain that is disproportionate to any inciting event. Diagnostic criteria include edema of the skin, discoloured skin, cool skin, abnormal hair growth and atrophy. Treatment of CRPS often includes occupational and physical therapy, pain control, and rehabilitation.

Trichloroethylene (TCE) Medical Experts

Trichloroethylene (TCE) is a neurotoxic solvent most commonly used to degrease and clean machine parts. There are currently approximately 3.5 million workers exposed to TCE, with 100,000 of them exposed on a full-time basis. Negative health effects of TCE can impact the central and peripheral nervous systems, skin, kidney, liver, and heart.
