RESUMO
OBJECTIVES: We sought to evaluate the impact of New York City's (NYC's) 2004 carbon monoxide (CO) alarm legislation on CO incident detection and poisoning rates. METHODS: We compared CO poisoning deaths, hospitalizations, exposures reported to Poison Control, and fire department investigations, before and after the law for 2000 to 2010. Use of CO alarms was assessed in the 2009 NYC Community Health Survey. RESULTS: Investigations that found indoor CO levels greater than 9 parts per million increased nearly 7-fold after the law (P < .001). There were nonsignificant decreases in unintentional, nonfire-related CO poisoning hospitalization rates (P = .114) and death rates (P = .216). After we controlled for ambient temperature, the law's effect on hospitalizations remained nonsignificantly protective (incidence rate ratio = 0.747; 95% confidence interval = 0.520, 1.074). By 2009, 83% of NYC residents reported having CO alarms; only 54% also recently tested or replaced their batteries. CONCLUSIONS: Mandating CO alarms significantly increased the detection of potentially hazardous CO levels in NYC homes. Small numbers and detection bias might have limited the discovery of significant decreases in poisoning outcomes. Investigation of individual poisoning circumstances since the law might elucidate remaining gaps in awareness and proper use of CO alarms.

Propylene glycol (PG), a widely used solvent and lubricant, is thought to have low toxicity when ingested. Three cases were identified where PG, either alone or in combination with other chemical agents, contributed to death. The decedent in whom PG was the sole agent was a 32-year-old schizophrenic man with cardiomegaly and renal impairment. The blood PG concentration was 4410 mg/L at least 9.5 h following ingestion.

BACKGROUND: Buprenorphine is an opioid agonist medication that is both safe and effective in the treatment of opioid use disorders and the prevention of opioid overdoses. Despite this, media coverage has highlighted public concerns about the potential safety consequences of buprenorphine misuse and diversion. To address the possible contribution of buprenorphine to overdose mortality, we systematically tested post mortem blood specimens from decedents who had died of an unintentional drug overdoses in 2013. METHODS: We retrospectively tested consecutive drug overdose cases that occurred from June through October 2013. Cases with available blood specimens were tested for buprenorphine and norbuprenorphine using liquid chromatography-tandem mass spectrometry. Toxicology results were linked to death certificates and case files from New York City Vital Statistics and New York City Office of the Chief Medical Examiner. RESULTS: Of the 98 unintentional drug overdose fatalities tested, only 2 (2.0%) tested positive for buprenorphine metabolites. All 98 unintentional fatalities involved multiple substances. CONCLUSIONS: Buprenorphine was infrequently found in drug overdose deaths in New York City. Since the safety and efficacy of buprenorphine are well documented, and overdoses resulting from buprenorphine treatment or diversion are very rare, facilitating access to buprenorphine treatment is strongly recommended.

We reviewed all 87 deaths from the Happy Land Social Club fire. All deaths were due to smoke inhalation. The carboxyhemoglobin (COHb) concentrations ranged from 37 to 93% with a mean of 76.5%. The vast majority (97%) of the decedents had a COHb concentration over 50%. Cyanide blood concentrations ranged from 0 to 5.5 mg/L with a mean of 2.2 mg/L. Nine decedents had no cyanide detected, and seven had cyanide concentrations of less than 1 mg/L. Fewer than one third of the decedents had thermal injuries, and most were partial thickness burns involving less than 20% body surface area. Ethanol was detected in 72% of decedents with a range of 0.01 to 0.29 g% and a mean blood concentration of 0.11 g%. Cocaine or cannabinoid use was identified in 9% of the decedents. All decedents were visually identified, and all had soot in the airway extending to the major bronchi. Carboxyhemoglobin concentrations corresponded well with deaths from smoke inhalation. Cyanide concentrations did not correspond with the extent of smoke inhalation, and the role of cyanide in contributing to these deaths is doubtful. Hydrogen chloride inhalation, as evidenced by comparison of the pH of tracheal mucosa to controls, was not a factor.

We reviewed 17 intentional ingestions of cyanide that occurred in New York City over a ten-year interval. The toxicologic and postmortem findings were reviewed. Certain occupations and nationalities of the decedents predominated among this group of suicides. Scientists, jewelers. and metal workers were common occupations among the decedents. In addition, 8 of 17 fatalities were West Indian/Caribbean Island and South American decedents, including three decedents from Guyana. Fourteen of the 17 fatalities were male. Pink lividity, a "bitter-almond" smell. and a hemorrhagic gastric mucosa were not prevailing findings in these decedents. A color test was used for screening for cyanide with confirmation and quantitation using gas chromatography.

MDMA ("ecstasy") has gained renewed popularity as a drug of abuse. To access the epidemiology and causes of death of MDMA-positive fatalities, all deaths investigated by the OCME that tested positive for MDMA (22 deaths) between January 1997 and June 2000 were reviewed. There were three deaths in each 1997 and 1998, eleven in 1999, and five in the first part of 2000. Of these 22 deaths, 13 were due to acute drug intoxications, 7 due to mechanical injury (blunt trauma, gunshot wounds), and 2 due to a combination of natural disease and acute drug intoxication. Evidence of recent opiate and/or cocaine use was found in 7 of the acute intoxication deaths and in none of the traumatic or combination natural/intoxication deaths. The race of all decedents was White between the ages of 17-41 years, and 18 of 22 were men.

Ibogaine is a naturally occurring psychoactive plant alkaloid that is used globally in medical and nonmedical settings for opioid detoxification and other substance use indications. All available autopsy, toxicological, and investigative reports were systematically reviewed for the consecutive series of all known fatalities outside of West Central Africa temporally related to the use of ibogaine from 1990 through 2008. Nineteen individuals (15 men, four women between 24 and 54 years old) are known to have died within 1.5-76 h of taking ibogaine. The clinical and postmortem evidence did not suggest a characteristic syndrome of neurotoxicity. Advanced preexisting medical comorbidities, which were mainly cardiovascular, and/or one or more commonly abused substances explained or contributed to the death in 12 of the 14 cases for which adequate postmortem data were available. Other apparent risk factors include seizures associated with withdrawal from alcohol and benzodiazepines and the uninformed use of ethnopharmacological forms of ibogaine.

BACKGROUND: Clenbuterol is a potent, long-acting beta-adrenergic agonist that has been reported as an adulterant of heroin. We describe an atypical syndrome in five users of clenbuterol-tainted heroin. METHODS: All cases were referred to a regional Poison Control Center. Urine and blood were analyzed using gas and liquid chromatography as well as mass spectrometry. CASE SERIES: Five heroin users presented with a syndrome characterized by muscular spasm, tremor, hyperreflexia, and elevated serum creatine phosphokinase concentrations. All patients lacked findings of acute clenbuterol toxicity but tested positive for clenbuterol and negative for strychnine and a battery of common potential adulterants. CONCLUSIONS: We report five cases of a novel neuromuscular syndrome in users of clenbuterol-adulterated heroin. It is unclear whether these reactions represent an atypical response to clenbuterol or another unidentified contaminant.

BACKGROUND: The U.S. Food and Drug Administration recently extended the Black Box warning on anti-depressants regarding pediatric suicidality to include young adults. The decision was guided by results from meta-analyses of 372 randomized controlled clinical trials of antidepressants for adults. Nearly all suicidality in those trials was nonfatal suicide attempts and ideation. Here, we consider whether antidepressants are linked with adult suicide deaths. METHOD: Subjects in this medical examiner surveillance study included all suicides, 18 years and older, in New York City from 2001-2004. Postmortem blood was analyzed for the presence of antidepressants. RESULTS: There were 1419 adult suicides in New York City during the study period. Antidepressants were detected at autopsy in 23.1% of the suicides who met criteria for toxicology analyses. Antidepressants were least prevalent in suicides aged 18-24 years (13.9%). CONCLUSIONS: Antidepressants were detected in less than one-quarter of adult suicides in New York City from 2001-2004. The majority of the suicides were not attributable to antidepressant use, and perhaps many could have been prevented with appropriate treatment. Although this study does not provide evidence for a link between antidepressant use and subsequent suicide, careful monitoring of patients receiving antidepressants remains critically important.

OBJECTIVES: Patients in emergency departments who use methadone frequently use tricyclic antidepressants (TCAs) and/or benzodiazepines (BZDs). This is a potentially dangerous drug combination. The authors hypothesized that the presence of methadone and a TCA, a BZD, or both is associated with an "accidental" overdose (AOD) death more often than a death from any other cause. METHODS: A retrospective chart review of New York City Office of Chief Medical Examiner data for 2003 was performed. Decedents who tested positive for methadone that were classified as an AOD death, as determined by the medical examiner, were compared with deaths from all other causes for the presence of a TCA, a BZD, or both. A logistical regression was performed to develop a multivariate model identifying additional variables associated with a methadone-positive AOD death. A p-value of <0.05 was considered significant, and 95% confidence intervals (CIs) were calculated. RESULTS: In 2003, there were 5,817 medical examiner cases, of which 500 (8.6%) were methadone positive. Of the methadone-positive cases, 493 were available for analysis; 95 (19.3%) were TCA positive and 158 (32.0%) were BZD positive. The odds of having an AOD death in methadone-positive decedents testing TCA positive, BZD positive, or both were 2.11 (95% CI = 1.32 to 3.37; p < 0.01) for TCAs, 1.66 (95% CI = 1.12 to 2.45; p < 0.02) for BZDs, and 4.34 (95% CI = 1.97 to 9.56; p < 0.001) for both. The multivariate logistic regression of analytes revealed the following covariates associated with an AOD death as well: amitriptyline, cocaine, morphine, or opiates. CONCLUSIONS: Among the methadone-positive cases, testing positive for a TCA, a BZD, or both was associated with an AOD death.
