Summary
Long-term industrial solvent exposure to trichloroethylene (TCE) can cause disabling myoclonic encephalopathy. This case highlights severe neurological damage from workplace TCE exposure, even after cessation of exposure.
Area of Science:
- Neuroscience
- Toxicology
- Occupational Health
Background:
- Trichloroethylene (TCE) is a common industrial solvent with known cardiovascular and central nervous system toxicity.
- Occupational exposure can occur via inhalation, ingestion, or skin absorption.
Observation:
- A 25-year-old woman developed disabling myoclonic encephalopathy after 18 months of workplace TCE exposure.
- Neurological symptoms progressed despite cessation of exposure, with thalamic and cerebellar involvement.
Findings:
- Non-toxicological causes for the encephalopathy were ruled out.
- The patient experienced severe limitations in daily activities and was deemed permanently disabled.
- Symptomatic treatment provided only partial relief.
Implications:
- This case underscores the potential for severe, progressive neurological sequelae from chronic TCE exposure.
- Highlights the importance of recognizing and managing occupational solvent neurotoxicity.
- Emphasizes the need for stringent workplace safety measures to prevent solvent-related disabilities.

01:29Hepatic Encephalopathy
DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
01:26Anticholinesterase Agents: Poisoning and Treatment
Anticholinesterases, also known as cholinesterase inhibitors, work by blocking the breakdown of acetylcholine, leading to its accumulation in the synaptic cleft. This accumulation indirectly enhances both muscarinic and nicotinic actions. These agents are classified as reversible or irreversible based on their mechanism of action.
Irreversible agents form a strong bond with the cholinesterase enzyme, making it inactive. The breakdown of the phosphorylated enzyme is slower than the...

01:36Types of Toxins
Humans continually engage with an environment rich in potentially harmful chemicals. These are introduced to our bodies through inhalation, ingestion, or skin contact. These chemicals exist in various forms, such as air and environmental pollutants, agricultural chemicals, organic solvents, and heavy metals.
Air pollutants, primarily gases, pose significant threats to respiratory health, leading to conditions like hypoxia, lung cancer, and in extreme cases, death.

01:19Encephalitis l: Introduction
Encephalitis is inflammation of the brain parenchyma, most often due to infections or autoimmune processes. It presents with neuropsychiatric features such as fever, altered mental status, behavioral changes, cognitive dysfunction, seizures, focal deficits, and sometimes autonomic instability. In some cases, the meninges are also involved, resulting in meningoencephalitis.Infectious CausesInfectious encephalitis is most commonly viral but can also result from bacterial, fungal, or parasitic...
01:26Toxic Reactions: Overview
When toxic substances penetrate the human body, they disseminate to various tissues, undergoing metabolic changes. This process yields reactive metabolites that may covalently bind with specific target molecules, resulting in toxicity.
Toxicity falls into two primary categories: local and systemic.
Local toxicity appears at the exposure site, such as protein denaturation caused by caustic substances.
In contrast, systemic toxicity requires the toxic agent's absorption and distribution,...

01:28Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
