ObjectivesIn 2017, the Centers for Disease Control and Prevention reported more than 47,600 deaths as a result of opioid overdose in the United States. In an effort to reduce these deaths, California passed legislation providing pharmacists with the ability to furnish naloxone without a prescription. Our study examined pharmacies in San Francisco that furnished naloxone and provided guidance for pharmacies seeking to develop similar programs. The study aims were to (1) identify the legal, structural, social-environmental, and financial components of a pharmacy model that allows for successful naloxone distribution, (2) evaluate the attitudes and beliefs of pharmacy staff members toward patients receiving or requesting naloxone, and (3) assess relationships between these attitudes and beliefs and naloxone furnishing at the pharmacy.MethodsThis cross-sectional study used a series of semistructured interviews of pharmacy staff in San Francisco conducted April-October 2019. Through a thematic, inductive analysis of collected data, emerging themes were mapped to the primary study aims.ResultsWe interviewed 14 pharmacists and pharmacy technicians at 4 community pharmacies. We identified 4 factors for success in implementing a naloxone furnishing protocol: administrative-led efforts, pharmacist-led efforts, increasing pharmacist engagement, and increasing patient engagement. The respondents also discussed the approaches they used to overcome previously identified barriers: cost, time, expectations of unwanted clientele, and patients' feelings of stigma.ConclusionPharmacists' approaches to implementing naloxone furnishing had common features across locations, suggesting many of these strategies could be replicated in other community pharmacies.

BackgroundTapentadol (TAP) and tramadol (TRA) provide pain relief through similar monoaminergic and opioid agonist properties.ObjectiveTo compare clinical effects and medical outcomes between TAP and TRA exposures reported to the National Poison Data System of the American Association of Poison Control Centers.MethodsA retrospective cohort study was conducted analyzing national data for single medication TAP or TRA cases reported from June 2009 through December 2011. Case outcomes, dichotomized as severe versus mild; clinical effects; and use of naloxone were compared.ResultsThere were 217 TAP and 8566 TRA cases. Significantly more severe outcomes were associated with TAP exposures for an all-age comparison (relative risk [RR] = 1.24; 95% CI = 1.04-1.48), and for the

BackgroundWe assessed the predictive value of selected factors on the outcomes of death and prolonged renal insufficiency (RI) from ethylene glycol poisoning.MethodsRetrospective, observational California Poison Control System study, over a 10-year period (1999-2008). We compared 2 groups. The first group (D/RI) included 59 patients who died (9 patients) or had prolonged RI (50 patients). Prolonged RI was defined as kidney injury in which dialysis was required for greater than 3 days after presentation. The second group (RECOV) of 62 patients had an uncomplicated recovery. Secondarily, we evaluated the association of time to antidote (ethanol and/or fomepizole) and time to dialysis with these outcomes.ResultsThe D/RI group was more likely than the RECOV group to present comatose, have seizures, and require intubation. The D/RI group had a lower mean initial arterial pH of 7.03 (standard deviation [SD] 0.20), compared to 7.27 (SD 0.14) for the RECOV group. The D/RI group had a higher initial creatinine (1.7 mg/dL, SD 0.71) than that of the RECOV group (1.0 mg/dL, SD 0.33). Patients with a time to antidote greater than 6 hours had a higher odds of dying or having prolonged RI (OR 3.34, 95% CI : 1.21-9.26) Patients with a time to dialysis greater than 6 hours had a lower odds of dying or having prolonged RI (OR 0.36, 95% CI : 0.15-0.87).ConclusionCompared to survivors with an uncomplicated recovery, patients poisoned with ethylene glycol who died or had prolonged RI were more likely to exhibit clinical signs such as coma, seizures, and acidosis. Antidote administration within 6 hours is associated with better outcomes, unlike earlier time to dialysis.

BackgroundVentricular dysrhythmias are a serious consequence associated with drug overdose and chemical poisoning. The risk factors for the type of ventricular dysrhythmia and the outcomes by drug class are not well documented.ObjectiveThe aim of this study was to determine the most common drugs and chemicals associated with ventricular dysrhythmias and their outcomes.MethodsWe reviewed all human exposures reported to a statewide poison control system between 2002 and 2011 that had a documented ventricular dysrhythmia. Cases were differentiated into two groups by type of arrhythmia: (1) ventricular fibrillation and/or tachycardia (VT/VF); and (2) torsade de pointes (TdP).ResultsAmong the 300 potential cases identified, 148 cases met the inclusion criteria. Of these, 132 cases (89%) experienced an episode of VT or VF, while the remaining 16 cases (11%) had an episode of TdP. The most commonly involved therapeutic classes of drugs associated with VT/VF were antidepressants (33/132, 25%), stimulants (33/132, 25%), and diphenhydramine (16/132, 12.1%). Those associated with TdP were antidepressants (4/16, 25%), methadone (4/16, 25%), and antiarrhythmics (3/16, 18.75%). Drug exposures with the greatest risk of death in association with VT/VF were antidepressant exposure [odds ratio (OR) 1.71; 95% confidence interval (CI) 0.705-4.181] and antiarrhythmic exposure (OR 1.75; 95% CI 0.304-10.05), but neither association was statistically significant. Drug exposures with a statistically significant risk for TdP included methadone and antiarrhythmic drugs.ConclusionsAntidepressants and stimulants were the most common drugs associated with ventricular dysrhythmias. Patients with suspected poisonings by medications with a high risk of ventricular dysrhythmia warrant prompt ECG monitoring.

BackgroundPepper spray is a common lacrimator used by law enforcement and the public to subdue individuals and for self-defense. The risk factors for severe injury due to pepper spray exposure are not well documented and there is a lack of guidelines to identify patients that require transport and medical evaluation in an emergency department.ObjectiveThe aim of this study was to determine the prevalence of and circumstances associated with symptoms suggestive of tissue injury beyond transient irritation in persons exposed to pepper spray.MethodsWe reviewed all human exposures to pepper spray reported to a poison control system between 2002 and 2011. Cases were differentiated into 2 outcome groups: minor or self-limiting symptoms versus those with more severe symptoms suggestive of tissue injury that warranted a medical evaluation. A comparison of the variables between the outcome groups was performed using odds ratios (ORs), 95% confidence intervals (CIs), and associated P values.ResultsA total of 4,544 cases were identified and 3,671 met the inclusion criteria. Of these, 249 cases (6.8%) were found to have more severe symptoms that warranted a medical evaluation. There were no reported deaths. The cases with more severe symptoms most commonly involved the ocular (53.8%), respiratory (31.7%), and dermal (17.7%) organ systems. Factors with largest independent associations with more severe outcomes were use for law enforcement training (OR, 7.39; 95% CI, 2.98-18.28), direct intentional exposure for purposeful use to incapacitate (OR, 3.02; 95% CI, 1.80-5.06), and for law enforcement on individual target suspects or crowd control (OR, 2.45; 95% CI, 1.42-4.23).ConclusionsThere was a low 1 in 15 potential risk for more severe adverse health effects in persons exposed to pepper spray that warranted a medical evaluation. The risk was highest when used for training of law enforcement personnel and involved severe ocular symptoms. This suggests that routine use of pepper spray for training of law enforcement or military personnel be reconsidered. Protective goggles may be an option when direct spraying into the face of trainees. Transport for medical evaluation should be considered for exposed persons that manifest persistent ocular or respiratory symptoms.

ObjectivesThe Internet may be the first source of information used by parents during a suspected poisoning of their children. Our primary aim was to assess the reliability of the Internet as a resource for information for parents to initially manage a suspected poisoning involving their child without outside consultation.MethodsWe distributed a self-administered survey to English-speaking parents to evaluate their Internet access behaviors so we could emulate their search strategies for a poisoning. A panel of clinical toxicologists performed an evaluation of Websites to determine the proportion that provided accurate and adequate information on common substances involved in poisonings.ResultsOf 21 parents surveyed, 15 (71%) used the Internet daily, with Google and Yahoo being the most commonly used search engines. Seven parents (39%) were somewhat to very likely to utilize the Internet during a poisoning scenario with prescription medications involving their child. Overall, only 27 (38%) of the Websites reviewed advised the user to call the poison center with the proper 800 telephone number, whereas no Website provided adequate information to manage the poisoning without outside consultation. Few Websites provided information on the toxic dose (13%), how to determine whether to manage the poisoning at home or in a hospital (22%), or first aid (28%).ConclusionsThe information provided on the Internet for substances involved in poisonings is variable and often incomplete. Reliance on the Internet for poisonings could create needless delays and inappropriate assessments and actions to manage a pediatric poisoning incident.

The aim of this study was to report 3-year outcomes of toxicity, cosmesis, and local control using a once daily fractionation scheme (49.95 Gy in 3.33 Gy once daily fractions) for accelerated partial breast irradiation (APBI) using three-dimensional conformal radiotherapy (3D-CRT). Between July 2008 and August 2010, women aged ≥40 years with ductal carcinoma in situ or node-negative invasive breast cancer ≤3 cm in diameter, treated with breast-conserving surgery achieving negative margins, were accrued to a prospective study. Women were treated with APBI using 3-5 photon beams, delivering 49.95 Gy over 15 once daily fractions over 3 weeks. Patients were assessed for toxicities, cosmesis, and local control rates before APBI and at specified time points. Thirty-four patients (mean age 60 years) with Tis 0 (n = 9) and T1N0 (n = 25) breast cancer were treated and followed up for an average of 39 months. Only 3% (1/34) patients experienced a grade 3 subcutaneous fibrosis and breast edema and 97% of the patients had good/excellent cosmetic outcome at 3 years. The 3-year rate of ipsilateral breast tumor recurrence (IBTR) was 0% while the rate of contralateral breast events was 6%. The 3-year disease-free survival (DFS), overall survival (OS), and breast cancer-specific survival (BCSS) was 94%, 100%, and 100%, respectively. Our novel accelerated partial breast fractionation scheme of 15 once daily fractions of 3.33 Gy (49.95 Gy total) is a remarkably well-tolerated regimen of 3D-CRT-based APBI. A larger cohort of patients is needed to further ascertain the toxicity of this accelerated partial breast regimen.

BackgroundWe examined forensic serum toxicology and pharmacogenomics data from a woman on codeine shortly before she caused a motor vehicle accident.MethodsA woman driving erratically collided with a parked car of a highway seriously injuring 2 men working to repair the parked vehicle. The woman tested positive for codeine, acetaminophen and barbital. She had been taking these medications for 20 years due to migraine headache. Serum toxicology and genotype analysis for cytochrome P450, UDP glucuronosyltransferase, and other metabolizing enzymes were measured.ResultsThe woman was tried and convicted of driving under the influence resulting in bodily harm and was sentenced to 6 years. Toxicology results on peripheral blood showed a total and free codeine of 840 and 348 μg/L, respectively, and total morphine of 20 μg/L (17, 3, and 0 μg/L for morphine-3-glucuronide, morphine-6-glucuronide, and free morphine, respectively). She was heterozygous for CYP 2D6 *2/*4 (extensive/poor metabolism) and heterozygous for UGT 2B7 *1/*2 (extensive/ultra-rapid metabolism). The woman was also taking fluoxetine and bupropion which are strong inhibitors of CYP 2D6.ConclusionsBased on her genotype and phenotype and reports by the arresting officer, we suggest that the subject in question was not intoxicated by opiates at the time of her motor vehicle accident and may have been falsely incarcerated.

Emperor penguins, the largest of all the penguin species, attain heights of nearly four feet and weigh up to 99 pounds. Many students are not motivated to learn mathematics when textbook examples contain largely nonexistent contexts or when the math is not used to solve significant problems found in real life. This article's project explores how male Emperor penguins are able to survive in Antarctica. In so doing, it addresses measurement, applies geometry, and helps foster problem-solving skills, all within a real-life context. Students use a fairly small set of background skills to combine and apply geometry, measurement, conversions, and (possibly) statistics to the problem of computing penguin body surface area and heat conservation. Students become aware of the concept of measurement uncertainty and how it could affect the outcome of the problems they were solving. Finally, students learn about model assumptions and questioned their validity and effect on the outcome of their computations. They combine many areas of mathematics with science to solve a real-life problem; this activity is meaningful and fun learning experience for both teacher and student.
