Elevated Blood Lead Levels Associated with Retained Bullet Fragments - United States, 2003-2012.

An estimated 115,000 firearm injuries occur annually in the United States, and approximately 70% are nonfatal (1). Retained bullet fragments (RBFs) are an infrequently reported, but important, cause of lead toxicity; symptoms are often nonspecific and can appear years after suffering a gunshot wound (2,3). Adult blood lead level (BLL) screening is most commonly indicated for monitoring of occupational lead exposure; routine testing of adults with RBFs is infrequent (3). States collaborate with CDC's National Institute for Occupational Safety and Health (NIOSH) to monitor elevated BLLs through the Adult Blood Lead Epidemiology and Surveillance (ABLES) program (4,5). To help assess the public health burden of RBFs, data for persons with BLLs ≥10 µg/dL reported to ABLES during 2003-2012 were analyzed. An RBF-associated case was defined as a BLL ≥10 µg/dL in a person with an RBF. A non-RBF-associated case was defined as a BLL ≥10 µg/dL without an RBF. During 2003-2012, a total of 145,811 persons aged ≥16 years with BLLs ≥10 µg/dL were reported to ABLES in 41 states. Among these, 457 RBF-associated cases were identified with a maximum RBF-associated BLL of 306 µg/dL. RBF-associated cases accounted for 0.3% of all BLLs ≥10 µg/dL and 4.9% of BLLs ≥80 µg/dL. Elevated BLLs associated with RBFs occurred primarily among young adult males in nonoccupational settings. Low levels of suspicion of lead toxicity from RBFs by medical providers might cause a delay in diagnosis (3). Health care providers should inquire about an RBF as the potential cause for lead toxicity in an adult with an elevated BLL whose lead exposure is undetermined.

Surveying Local Health Departments and County Emergency Management Offices on Cooling Centers as a Heat Adaptation Resource in New York State.

Local agencies in New York State (NYS) set up cooling centers to provide relief from summer-time heat especially for people with limited access to air-conditioning. We aimed to determine cooling center locations in NYS, and explore county agencies' involvement in organizing and promoting utilization of cooling centers. We conducted a survey among county health and emergency preparedness offices in NYS (excluding NYC) and explored official county websites. We identified 377 cooling centers, mostly in metropolitan areas of NYS. Although 47 % of counties listed locations online, only 29 % reported locations via survey. Radio (90 %) and internet (84 %) were popular for information dissemination. Air-conditioning was available at all indoor cooling center facilities. Cooling centers in 13 % of the counties were accessible by either public transportation or shuttles arranged by the facility. About 38 % counties do not consider cooling centers important in their region or promote informal cooling centers. More than a third of New York counties had neither cooling centers nor plans to establish a cooling center as extreme heat was not perceived as a threat in their region.

Extreme heat awareness and protective behaviors in New York City.

Heat waves can be lethal and routinely prompt public warnings about the dangers of heat. With climate change, extreme heat events will become more frequent and intense. However, little is known about public awareness of heat warnings or behaviors during hot weather. Awareness of heat warnings, prevention behaviors, and air conditioning (AC) prevalence and use in New York City were assessed using quantitative and qualitative methods. A random sample telephone survey was conducted in September 2011 among 719 adults and follow-up focus groups were held in winter 2012 among seniors and potential senior caregivers. During summer 2011, 79 % of adults heard or saw a heat warning. Of the 24 % who were seniors or in fair or poor health, 34 % did not own AC or never/rarely used it on hot days. Of this subgroup, 30 % were unaware of warnings, and 49 % stay home during hot weather. Reasons for not using AC during hot weather include disliking AC (29 %), not feeling hot (19 %), and a preference for fans (18 %). Seniors in the focus groups did not perceive themselves to be at risk, and often did not identify AC as an important health protection strategy. While heat warnings are received by most New Yorkers, AC cost, risk perception problems, and a preference for staying home leave many at risk during heat waves. Improving AC access and risk communications will help better protect the most vulnerable during heat waves.

Health effects of coastal storms and flooding in urban areas: a review and vulnerability assessment.

Coastal storms can take a devastating toll on the public's health. Urban areas like New York City (NYC) may be particularly at risk, given their dense population, reliance on transportation, energy infrastructure that is vulnerable to flood damage, and high-rise residential housing, which may be hard-hit by power and utility outages. Climate change will exacerbate these risks in the coming decades. Sea levels are rising due to global warming, which will intensify storm surge. These projections make preparing for the health impacts of storms even more important. We conducted a broad review of the health impacts of US coastal storms to inform climate adaptation planning efforts, with a focus on outcomes relevant to NYC and urban coastal areas, and incorporated some lessons learned from recent experience with Superstorm Sandy. Based on the literature, indicators of health vulnerability were selected and mapped within NYC neighborhoods. Preparing for the broad range of anticipated effects of coastal storms and floods may help reduce the public health burden from these events.

Low-risk criteria for pelvic radiography in pediatric blunt trauma patients.

CONTEXT: The American College of Surgeons recommends that any patient with blunt trauma undergoes radiographic evaluation, including a radiograph of the pelvis. Studies have questioned the use of such routine pelvic radiographs (PXR) in pediatrics. Selective elimination of PXR would save time, money and unshielded radiation exposure to the gonads. OBJECTIVE: To determine if a defined set of historical and clinical factors could predict low risk for pelvic fracture and incorporate these factors into a clinical decision guideline. DESIGN, SETTING, AND PATIENTS: A retrospective chart review of all blunt trauma patients 25 years or younger in whom a PXR was obtained from January 2002 to June 2006 presenting to an urban level 1 trauma center. A total of 579 patients underwent 580 trauma evaluations. MAIN OUTCOME MEASURES: Variables including sex, mechanism of injury, Glascow Coma Score, Pediatric Trauma Score, fall height, lower extremity injury, blood on rectal examination, blood at meatus, and clinical need for computed tomography (CT) were compared with outcomes of pelvic fracture and pelvic fracture requiring surgical intervention. RESULTS: There were 22 pelvic fractures identified, resulting in a fracture rate of 4%. The negative predictive value for pelvic fracture was 98.3% (95% confidence interval [95% CI], 96.9%-99.2%) if no lower extremity injury was present, 99% (95% CI, 98.2%-99.6%) if physical examination of the pelvis was normal, and 99.5% (95% CI, 98.6%-99.9%) if there was no need for abdominopelvic CT. The negative predictive value was 100% (95% CI, 98.8%-100%) if any one of these 3 factors is present. CONCLUSIONS: Using the clinical findings of (1) lack of lower extremity injury, (2) lack of an abnormal physical examination of the pelvis, and (3) no need for abdominopelvic CT, pelvic fracture can be reliably excluded. Pelvic radiography can be eliminated in the evaluation of these patients, potentially decreasing time expenditure, radiation exposure, and cost.

A cluster of children with seizures caused by camphor poisoning.

BACKGROUND: Isolated cases of camphor-induced seizures have been reported in young children after gastrointestinal, dermal, and inhalation exposure. In 1982, after a series of unintentional ingestions of camphor products, the US Food and Drug Administration restricted the camphor content to <11% in some products intended for medicinal use. Camphor products intended for use as pesticides must be registered with the US Environmental Protection Agency. Still, many imported camphor-containing products fail to meet Food and Drug Administration and Environmental Protection Agency requirements for labeling and content. OBJECTIVE: To describe a cluster of cases of camphor-associated seizure activity resulting from the availability of imported camphor products in certain ethnic populations that use it as a natural remedy. METHODS: We present 3 cases of seizures associated with imported, illegally sold camphor in young children who presented to a large, urban children's hospital in Bronx, New York, during a 2-week period. RESULTS: The children's ages ranged from 15 to 36 months. Two children ingested camphor, and 1 child was exposed through repetitive rubbing of camphor on her skin. All 3 patients required pharmacologic intervention to terminate the seizures. One patient required bag-valve-mask ventilation for transient respiratory depression. All 3 patients had leukocytosis, and 2 patients had hyperglycemia. Exposure occurred as a result of using camphor for spiritual purposes, cold remedy, or pest control. After identification of these cases, the New York City Department of Health released a public health warning to keep camphor products away from children. Similar warnings were issued later by other state health departments. CONCLUSIONS: These cases highlight the toxicity associated with camphor usage in the community and that inappropriate use of illegally sold camphor products is an important public health issue. Camphor may be a common, yet unrecognized, source of seizures in children in certain ethnic populations that use it as a natural remedy. Efforts are needed to educate the communities about the hazards of using camphor products and to limit the illegal availability of these products.

Multisystem organ failure after large volume injection of castor oil.

We report a case of multisystem organ failure after large volume subcutaneous injection of castor oil for cosmetic enhancement. An unlicensed practitioner injected 500 mL of castor oil bilaterally to the hips and buttocks of a 28-year-old male to female transsexual. Immediate local pain and erythema were followed by abdominal and chest pain, emesis, headache, hematuria, jaundice, and tinnitus. She presented to an emergency department 12 hours postinjection. Persistently hemolyzed blood samples complicated preliminary laboratory analysis. She rapidly deteriorated despite treatment and developed fever, tachycardia, hemolysis, thrombocytopenia, hepatitis, respiratory distress, and anuric renal failure. An infectious diseases evaluation was negative. After intensive supportive care, including mechanical ventilation and hemodialysis, she was discharged 11 days later, requiring dialysis for an additional 1.5 months. Castor oil absorption was inferred from recovery of the Ricinus communis biomarker, ricinine, in the patient's urine (41 ng/mL). Clinicians should anticipate multiple complications after unapproved methods of cosmetic enhancement.

Grand rounds: nephrotoxicity in a young child exposed to uranium from contaminated well water.

CONTEXT: Private wells that tap groundwater are largely exempt from federal drinking-water regulations, and in most states well water is not subject to much of the mandatory testing required of public water systems. Families that rely on private wells are thus at risk of exposure to a variety of unmeasured contaminants. CASE PRESENTATION: A family of seven--two adults and five children--residing in rural northwestern Connecticut discovered elevated concentrations of uranium in their drinking water, with levels measured at 866 and 1,160 microg/L, values well above the U.S. Environmental Protection Agency maximum contaminant level for uranium in public water supplies of 30 microg/L. The uranium was of natural origin, and the source of exposure was found to be a 500-foot well that tapped groundwater from the Brookfield Gneiss, a geologic formation known to contain uranium. Other nearby wells also had elevated uranium, arsenic, and radon levels, though concentrations varied widely. At least one 24-hr urine uranium level was elevated (> 1 microg/24 hr) in six of seven family members (range, 1.1-2.5 microg/24 hr). To assess possible renal injury, we measured urinary beta-2-microglobulin. Levels were elevated (> 120 microg/L) in five of seven family members, but after correction for creatine excretion, the beta-2-microglobulin excretion rate remained elevated (> 40 microg/mmol creatinine) only in the youngest child, a 3-year-old with a corrected level of 90 microg/mmol creatinine. Three months after cessation of well water consumption, this child's corrected beta-2-microglobulin level had fallen to 52 microg/mmol creatinine. SIGNIFICANCE: This case underscores the hazards of consuming groundwater from private wells. It documents the potential for significant residential exposure to naturally occurring uranium in well water. It highlights the special sensitivity of young children to residential environmental exposures, a reflection of the large amount of time they spend in their homes, the developmental immaturity of their kidneys and other organ systems, and the large volume of water they consume relative to body mass.

Effective risk communication in children's environmental health: lessons learned from 9/11.

In situations with visible threats to children's health, pediatric health care providers must be prepared to communicate the health risks of environmental exposures. Several factors influence the effectiveness of such discussions: whether the individual providing the information is considered a reliable source, the familiarity of the physician and parent/guardian with these issues, and the limited research specifically assessing risk of exposure in childhood. This article describes the theory behind effective risk communication using examples from events following September 11, 2001. It shares lessons learned and provides a template for risk communication that can guide pediatric providers.

The environment in pediatric practice: a study of New York pediatricians' attitudes, beliefs, and practices towards children's environmental health.

Chronic diseases of environmental origin are a significant and increasing public health problem among the children of New York State, yet few resources exist to address this growing burden. To assess New York State pediatricians self-perceived competency in dealing with common environmental exposures and diseases of environmental origin in children, we assessed their attitudes and beliefs about the role of the environment in children's health. A four-page survey was sent to 1,500 randomly selected members of the New York State American Academy of Pediatrics in February 2004. We obtained a 20.3% response rate after one follow-up mailing; respondents and nonrespondents did not differ in years of licensure or county of residence. Respondents agreed that the role of environment in children's health is significant (mean 4.44 +/- 0.72 on 1-5 Likert scale). They voiced high self-efficacy in dealing with lead exposure (mean 4.16-4.24 +/- 0.90-1.05), but their confidence in their skills for addressing pesticides, mercury and mold was much lower (means 2.51-3.21 +/- 0.90-1.23; p < 0.001). About 93.8% would send patients to a clinic "where pediatricians could refer patients for clinical evaluation and treatment of their environmental health concerns." These findings indicate that New York pediatricians agree that children are suffering preventable illnesses of environmental origin but feel ill-equipped to educate families about common exposures. Significant demand exists for specialized centers of excellence that can evaluate environmental health concerns, and for educational opportunities.
