MMWR Morb Mortal Wkly Rep 2019 68 (50) 1166-1167 In July 2019, a Mexican-American woman aged 47 years in Sacramento, California, sought medical care for dysesthesias and weakness of her upper extremities. Over the ensuing 2 weeks of outpatient follow-up, her condition progressed to dysarthria, blurry vision, and gait unsteadiness, leading to hospital admission. While hospitalized, her condition declined rapidly to an agitated delirium. Two weeks into the hospitalization, screening blood and urine tests detected mercury concentrations exceeding the upper limit (UL) of quantification, indicative of abnormally high values of mercury (>160 μg/L [blood] and >80 μg/L [urine]). The hospital notified the California Poison Control System (CPCS) and the California Department of Public Health (CDPH). CPCS recommended oral dimercaptosuccinic acid, 10 mg/kg every 8 hours, which was administered via feeding tube. CDPH interviewed the patient’s family and learned that the patient was a long-term user of skin lightening creams obtained from Mexico (applied to the face twice daily for the past 7 years); the cream was analyzed and found to contain 12,000 ppm mercury. Mercury levels from the hospital specimens that initially implicated mercury were 2,620 μg/L blood mercury (reference population UL <1.81 μg/L)* and 110 μg/L urine mercury (UL <0.90 μg/L). A second blood specimen collected 11 days after the hospital initiation of ongoing dimercaptosuccinic acid chelation therapy detected 1,114 μg/L mercury. |

MMWR Morb Mortal Wkly Rep 2018 67 (11) 333-336 Hurricane Maria made landfall in Puerto Rico on September 20, 2017, causing major damage to infrastructure and severely limiting access to potable water, electric power, transportation, and communications. Public services that were affected included operations of the Puerto Rico Department of Health (PRDOH), which provides critical laboratory testing and surveillance for diseases and other health hazards. PRDOH requested assistance from CDC for the restoration of laboratory infrastructure, surveillance capacity, and diagnostic testing for selected priority diseases, including influenza, rabies, leptospirosis, salmonellosis, and tuberculosis. PRDOH, CDC, and the Association of Public Health Laboratories (APHL) collaborated to conduct rapid needs assessments and, with assistance from the CDC Foundation, implement a temporary transport system for shipping samples from Puerto Rico to the continental United States for surveillance and diagnostic and confirmatory testing. This report describes the initial laboratory emergency response and engagement efforts among federal, state, and nongovernmental partners to reestablish public health laboratory services severely affected by Hurricane Maria. The implementation of a sample transport system allowed Puerto Rico to reinitiate priority infectious disease surveillance and laboratory testing for patient and public health interventions, while awaiting the rebuilding and reinstatement of PRDOH laboratory services. |
