Insights
This case study presents chronic tetraethyl lead poisoning in a four-person family. Environmental exposure led to severe neurological and organ damage, highlighting the need for prompt toxicological diagnosis.
Area of Science:
- Environmental Toxicology
- Clinical Toxicology
- Neurology
Background:
- Chronic exposure to heavy metals can lead to severe health issues.
- Tetraethyl lead (TEL) poisoning is a serious environmental health concern.
- Early diagnosis and intervention are crucial for managing heavy metal toxicity.
Observation:
- A family presented with diverse symptoms including behavioral changes, hallucinations, nausea, vomiting, and diarrhea.
- Elevated liver enzymes (CPK, ALT, AST, GTP, LDH) were detected in all affected family members.
- High serum lead concentrations and confirmed diethyl lead in urine indicated tetraethyl lead poisoning.
Findings:
- The study identified chronic tetraethyl lead poisoning in a four-person family.
- Neurological dysfunction, liver damage, and cardiovascular issues were observed.
- Diagnosis was confirmed through clinical presentation and extensive toxicological testing.
Implications:
- This case underscores the importance of considering environmental factors in neurological and systemic illnesses.
- Prompt identification of heavy metal exposure sources is vital for family health.
- Public health awareness and environmental monitoring are essential to prevent such poisoning incidents.
Unlabelled:
The aim of this study was the presentation of the chronic tetraethyl lead poisoning of the 4 person family in the place of settlement.
Case Report:
15.5-years-old man was admitted to the regional Pediatric Ward because of changes of behavior, hallucinations, agitation. Nausea, vomiting, metallic taste and diarrhea were observed prior to the admission. In the case history, there were no data suggested of the toxic origin of the disorder . The CSF examination and CT of the brain were normal. Increased activity of CPK, ALT, AST, GTP, LDH in the blood were found. Paranoid syndrome was diagnosed by psychiatric evaluation. The patients' mother presented similar signs in almost the same time. The laboratory tests of the blood taken from the patients' father and older brother revealed the increase activity of the same enzymes (CPK, ALT, AST, LDH). All family was admitted to the Department of Clinical Toxicology in Kraków because of suspicion of the heavy metal poisoning. The toxicological laboratory test showed in all described patients the toxic serum lead concentration accordingly: 440 microg/l--older brother, 490 microg/l--father, 508 microg/l--mother and 635 microg/l--primary described patient. Because of the fact, that were no characteristic for lead poisoning changes in blood picture, the toxicological investigations were continued. As a result of these examinations presence of a diethyl lead in urine was confirmed. In the evaluation of the multiorgan damages connected with tetraethyl lead poisoning, we paid special attention on CSN dysfunctions. The USG and scintigraphy examinations revealed the liver damage. The different kinds of arrhythmias indicated on cardiovascular system damage. Based on clinical presentation and laboratory investigations the chronic tetraethyl lead poisoning was diagnosed.
