Mercury toxicity: a family case report.

Background: Environmental pollution exposes humans to toxic substances. Herein we present 5 family members aged20-54 years that were poisoned by liquid mercury.

Case Reports: Case 1 presented to our clinic with cough, fever, and night sweats. The patient had neutropenia, anemia,and pneumonia, rapidly developed acute respiratory distress syndrome (ARDS), and died on day 4 of hospitalization.Her WBC count was 0.4 × 10³ mm-3 (normal range: 4.3-10.3 × 103 mm-3) and Hb was 10.8 g dL-1 (normal range: 11.5-16.0 g dL-1). Case 2 presented with bicytopenia; the leukocyte count was 1.3 × 103 mm-3 (normal range: 4.3-10.3 × 103mm-3) and the PLT count was 88 × 103 mm-3 (normal range: 150-400 × 103 mm-3). Cases 2 and 3 had toxic peripheralneuropathy. The PLT count in case 3 was 123 × 103 mm-3 (normal range: 150-400 × 103 mm-3). Cases 4 and 5 presentedwith fatigue and headache; these 2 patients did not have positive findings, apart from high levels of mercury in theblood. We have written informed consent.

Conclusion: We think that heavy metal exposure-although rare-should be considered in patients that present withnumerous symptoms involving multiple systems, including the cardiovascular, respiratory, and neurological systems.The present report is unique in that in describes mercury poisoning in 5 members of the same family.
