RESUMEN

BACKGROUND: The estimated serum osmolality is a measurement of solutes in the blood, including sodium, glucose, and urea, but also includes ethanol and toxic alcohols (e.g., methanol, ethylene glycol, diethylene glycol, isopropyl alcohol, propylene glycol) when present. These rarely measured toxic alcohols can elevate the serum osmolality, giving the true measured osmolality. The difference between that and a calculated osmolality is the osmolal gap, which can be elevated in many clinical scenarios such as renal failure, ingestion of toxic alcohols, diabetic ketoacidosis, shock, and others. CASE REPORT: We report a patient with a history of alcohol use disorder who came to the Emergency Department with an abnormally elevated osmolal gap in the setting of altered mental status. The patient's increased osmolal gap was further investigated while he was promptly treated with fomepizole, thiamine, and urgent hemodialysis. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: We discuss the differential diagnosis for substances that increase the osmolal gap with respective ranges of elevation. This case demonstrates that although osmolal gap elevation is often attributed to the presence of toxic alcohols, other common etiologies may account for the gap, including acute renal failure and multiple myeloma.

RESUMEN

Background: Poison centers develop triage threshold guidelines for pediatric metformin ingestions. Our network uses 1700 mg, or 85 mg/kg. Objective: To describe the dose, clinical course, and outcomes for inadvertent metformin ingestions in children 5 years old and younger reported to our statewide poison center network. Methods: We searched the poison center database 2011 to 2021 for metformin ingestions in patients 5 years and younger. Variables included age, sex, weight, dose, symptoms, outcome, and more. We used descriptive statistics with medians and interquartile ranges (IQR) for continuous variables. Results: Of 669 cases, exposures by age were 208 (31.1%) 1 to 2 years, and 275 (41.1%) 2 years. Weight was recorded in 342 (51.1%) (median 13.5 kg; IQR: 3.7 kg), and dose in 149 (22.3%) (median 500 mg; IQR: 500 mg). Milligram/kilogram values were available for 103 (15.4%) with median 42.4 mg/kg, IQR: 39 mg/kg. Most (647, 98.5%) exposures were unintentional. Most (445/669, 66.5%) were managed at a non-healthcare facility, while 204 (30.7%) were already at or referred to a healthcare facility. Of these 204 patients, 169 (82.8%) were evaluated and treated at the emergency department and discharged. Four (2%) were admitted to critical care, and 7 (3.4%) to the ward. Medical outcomes by effect were 5 (0.7%) minor, 2 (0.3%) moderate, 253 (37.8%) none, 292 (43.6%) not followed (minimal effects possible), and no major effects or deaths. Of 20 clinical occurrences reported, vomiting was most common (8, 1.2%). Conclusion: Despite little recorded dosage information, pediatric metformin ingestions under 85 mg/kg had predominantly uneventful medical outcomes.

RESUMEN

BACKGROUND: Cycas revoluta (sago cycad or palm) is a popular ornamental plant in the United States. All parts of the plant contain toxins such cycasin and beta-methylamino-l-alanine, the ingestion of which can be harmful to humans and animals. The objective of this study was to characterize C. revoluta exposures reported to poison centers. METHODS: Cases were C. revoluta exposures reported to Texas poison centers during 2000-2018. The distribution of cases by selected variables was determined. RESULTS: Of 192 total C. revoluta exposures, the most common exposure routes were ingestion (55.7%) and dermal (34.4%). The patient age distribution was 28.1% 5 years or less, 15.1% 6-12 years, 4.7% 13-19 years, and 50.5% 20 years or more; 55.2% were male. The exposure was unintentional in 92.2% of the cases and occurred at the patient's own residence in 94.8%. The patient was managed on site in 78.6% of the cases, already at/en route to a healthcare facility in 12.0%, and referred to a healthcare facility in 8.9%. The most common reported clinical effects were dermal (23.4%), particularly puncture/wound (16.1%), dermal irritation/pain (14.6%), and edema (8.9%), followed by gastrointestinal (13.0%), particularly vomiting (8.9%) and nausea (7.8%). CONCLUSION: Most of the C. revoluta exposures tended to be unintentional and occurred at home. Although most of the C. revoluta exposures involved ingestion, 35% were dermal, and the most frequently reported clinical effects were dermal followed by gastrointestinal. Most of the exposures were not serious and were managed outside of a healthcare facility.

RESUMEN

BACKGROUND: Melia azedarach, also known as the chinaberry tree, is native to Southeast Asia and northern Australia but has become an invasive species in the United States. M. azedarach contains limonoid tetranotriterpenes, found in highest concentrations in its berries. Ingestion has been reported to result in adverse clinical effects affecting the gastrointestinal, cardiovascular, respiratory, and neurologic systems. OBJECTIVE: The objective of this investigation was to describe M. azedarach ingestions in Texas. METHODS: Cases were M. azedarach ingestions reported to Texas poison centers from 2000-2018. The distribution of cases was determined for various factors related to patient demographics, ingestion circumstances, management, and outcome. RESULTS: Of 990 total M. azedarach ingestions, 87.4% involved the berry. There was a seasonal pattern with 42.9% reported between March and May. The patients were male in 55.1% of cases; 86.6% of the patients were ≤5 years of age. Patients were managed outside of a health care facility in 89.9% of cases; 95.2% of the ingestions resulted in no or at most minor clinical effects. The most frequently reported clinical effects were gastrointestinal (8.9%) and neurologic (2.1%). The most common treatments were dilution (67.2%) and food/snack (16.8%). CONCLUSION: In this study that focused on M. azedarach ingestions reported to Texas poison centers, the ingestions tended to involve berries. Most of the patients were young children. The ingestions often occurred between March and May. The ingestions typically were managed outside of a health care facility and did not result in serious outcomes. The most common clinical effects were gastrointestinal and neurologic.

RESUMEN

Marijuana is one of the most commonly consumed psychotropic drugs in the world. It has been associated with adverse cardiovascular reactions including acute coronary syndrome, but this information is not widely known among emergency medicine clinicians. This article describes cannabis use as a contributing factor to acute myocardial infarction in a young woman with chest pain.

RESUMEN

Opioid misuse is a growing epidemic among the civilian and military communities. Five hundred prospective, anonymous surveys were collected in the emergency department waiting room of a military tertiary care hospital over 3 weeks. Demographics, medical and military characteristics were investigated for association with opioid use. Univariate logistic models were used to characterize the probability of misuse in relation to the demographic, medical, and military-specific variables. Traumatic brain injury (TBI) and posttraumatic stress disorder were investigated within different age cohorts with adjustment for deployment. The opioid misuse rate disclosed by the subject was 31%. Subjects with TBI were less likely to misuse opioids. We found a trend among younger cohorts to have a higher likelihood for misusing opioids when diagnosed with TBI or posttraumatic stress disorder with history of deployment in the past 5 years. The most common form of misuse was using a previously prescribed medication for a new pain. Traumatic brain injury and/or enrollment in post-deployment recovery programs maybe protective against opioid misuse. Chronic opioid use among young soldiers maybe viewed as a weakness that could influence opioid misuse. Younger cohorts of active duty service members could be at higher risk for misuse. Efforts to enhance close monitoring of misuse should address these at-risk populations.

RESUMEN

STUDY OBJECTIVE: Diphenhydramine is a moderately lipophilic antihistamine with sodium channel blockade properties. It is consumed recreationally for mild hallucinogenic and hypnotic effects and causes dysrhythmias, seizures, and death with overdose. Intravenous lipid emulsion is a novel agent used to treat lipophilic drug overdose. Two case reports describe clinical improvement with intravenous lipid emulsion after diphenhydramine toxicity, but no prospective studies have been reported. Our objective is to determine whether intravenous lipid emulsion improved hypotension compared with sodium bicarbonate for severe diphenhydramine toxicity in a model of critically ill swine. METHODS: Twenty-four swine weighing 45 to 55 kg were infused with diphenhydramine at 1 mg/kg per minute until the mean arterial pressure reached 60% of baseline. Subjects were randomized to receive intravenous lipid emulsion (bolus of 7 mL/kg and then 0.25 mL/kg per minute) or sodium bicarbonate (2 mEq/kg plus an equal volume of normal saline solution). We measured pulse rate, systolic blood pressure, mean arterial pressure, cardiac output, QRS interval, and serum diphenhydramine level. Twelve animals per group provided a power of 0.8 and α of .05 to detect a 50% difference in mean arterial pressure. We assessed differences between groups with a repeated-measures linear model (MIXED) and Kaplan-Meier estimation methods. We compared systolic blood pressure, mean arterial pressure, and cardiac output with repeated measures ANOVA. RESULTS: Baseline weight, hemodynamic parameters, QRS interval, time to hypotension, and diphenhydramine dose required to achieve hypotension were similar between groups. After hypotension was reached, there was no overall difference between intravenous lipid emulsion and sodium bicarbonate groups for cardiac output or QRS intervals; however, there were transient differences in mean arterial pressure and systolic blood pressure, favoring intravenous lipid emulsion (difference: mean arterial pressure, sodium bicarbonate versus intravenous lipid emulsion -20.7 [95% confidence interval -31.6 to -9.8]; systolic blood pressure, sodium bicarbonate versus intravenous lipid emulsion -24.8 [95% confidence interval -37.6 to -12.1]). Time to death was similar. One intravenous lipid emulsion and 2 sodium bicarbonate pigs survived. End-of-study mean total serum diphenhydramine levels were similar. The mean lipid layer diphenhydramine level was 6.8 µg/mL (SD 3.1 µg/mL) and mean aqueous layer level 8.6 µg/mL (SD 5.5 µg/mL). CONCLUSION: In our study of diphenhydramine-induced hypotensive swine, we found no difference in hypotension, QRS widening, or diphenhydramine levels in aqueous layers between intravenous lipid emulsion and sodium bicarbonate.

RESUMEN

OBJECTIVES: Oseltamivir (Tamiflu) is approved by the Food and Drug Administration and is advertised for the treatment of influenza types A and B. Patient perceptions of its efficacy have not been adequately studied. Recent systematic reviews have called the benefits of this drug into question relative to the cost and adverse effect profile. We hypothesized that most people would be unaware of the efficacy, cost, or adverse effect profile of the drug. Our objective was to determine patient perceptions of efficacy, cost, and adverse effect profile of oseltamivir for the treatment of influenza. METHODS: This was a cross-sectional, multiple-choice, open-response survey of adult patients and adult caregivers of pediatric patients who presented to the emergency department (ED) with flu-like symptoms. Flu-like symptoms were defined as any respiratory symptom plus fever or body aches. The study took place during the 2014-2015 flu season at a rural ED. We analyzed the data, with descriptive statistics reported as frequencies/percentages for categorical data. Survey data collected as Likert scale data were summarized using mean, median, and mode. RESULTS: During the 4-month period, 70 surveys were completed. A total of 67% of the participants were women, with 84% younger than 40 years. Subjects younger than 40 years were more likely to have seen advertising for oseltamivir (31% vs 0%, P = 0.04). Less than half reported having received the flu vaccine that year. Most reported that oseltamivir was an effective treatment for the flu. Most overstated the perceived efficacy of oseltamivir. Most were not willing to take the medication if it had adverse effects, with the most deterring adverse effects being potential kidney and liver injury. CONCLUSIONS: In our study most patients reported overly positive expectations for the efficacy of oseltamivir for treating influenza. Most reported that commonly listed adverse effects would deter their use of the medication.

RESUMEN

Metformin-associated lactic acidosis or lacticemia has been widely reported as an adverse drug effect in diabetic patients with other significant comorbidities and in acute overdose in adults. Lacticemia has been reported twice in a previously healthy pediatric population, both of which were suicide attempts and required hemodialysis. We report a case of a 17-year-old, nondiabetic, healthy adolescent girl with metformin-associated lacticemia who intentionally overdosed on metformin, had no coingestants, and was treated only with crystalloids. Furthermore, she did not require intravenous bicarbonate administration or extracorporeal removal.

RESUMEN

Liver function test (LFT) increase is an early sign of acetaminophen (APAP) toxicity. Typically, when an acute overdose patient is evaluated and has an initial undetectable APAP level and normal liver enzymes, the patient is not treated with N-acetylcysteine, and liver enzymes are not expected to increase later. We report a case of moderate LFT increase despite normal LFTs and an undetectable APAP level after delayed presentation of an APAP ingestion. A 22-year-old male with no medical history ingested 15-25 hydrocodone/APAP tablets (5 mg/500 mg). His suicide note and his bunkmate corroborated the overdose time. He arrived at the emergency department 16 hours after ingestion. At that time, his APAP level was <10 µg/mL, and his liver enzymes were normal [aspartate transaminase (AST) 31 U/L and alanine transaminase (ALT) 34 U/L]. Twenty-nine hours after ingestion, the psychiatry team obtained LFTs (AST 45, ALT 61). He had persistent nausea and diffuse abdominal pain. On repeat analysis, the APAP level at 36 hours was found to be <10 µg/mL, AST 150, and ALT 204. After 2 more days of increasing LFTs and persistent abdominal pain and nausea, the toxicology department was consulted, the patient was transferred to the medicine department, and intravenous N-acetylcysteine was started 66 hours after ingestion. He was treated for 16 hours and had a significant decline in LFTs and symptom resolution. His prothrombin time, bilirubin, lactate, creatinine, and mental status were normal throughout the admission. Other cases of LFT increase were excluded. Our case report illustrates that a moderate increase in liver transaminase may occur despite an initial undetectable APAP level and normal transaminases after a delayed presentation. In our case, no serious clinical effects were reported.

RESUMEN

N-Acetylcysteine (NAC) dosing for acetaminophen (APAP) overdose is weight based (150 mg/kg intravenous or 140-mg/kg oral loading dose) and, in the United States, the dosing protocol recommends using a maximum patient weight of 100 and 110 kg, respectively. Little clinical data describe the use of NAC for APAP poisoning in patients weighing >100 kg. The aim of this study was to describe the demographics, outcomes, and adverse event (AE) rates of patients weighing >100 kg treated with oral or IV NAC for APAP poisoning. Patients were identified from a multicenter retrospective NAC safety study for APAP overdose. We included patients with a recorded weight. Trained chart abstractors used a standardized form. Selected data included age, gender, weight, serum alanine transaminase, and aspartate transaminases, coingestants, NAC administration route, ingestion type, AEs, and outcome [hepatotoxicity (alanine transaminase > 1000 U/L), liver transplant, or death]. Descriptive statistics were used. Of 503 study patients, 37 (7.4%) had recorded weights >100 kg. The median (range) weight was 110 kg (101-160). The median (range) dosing for patients treated with oral NAC was 140 mg/kg (127-143 mg/kg) and 150 (108-168) mg/kg for IV NAC. Hepatotoxicity occurred in 12/36 (33.3%) patients. Death occurred in 4/36 (11.1%) patients. Thirteen NAC-related AEs occurred in 8 patients (1.6 per person). All AEs were related to NAC and were rated nonserious by the reviewer. Clinicians use an actual weight-based NAC dose rather than a maximum weight cutoff dose. Hepatotoxicity was common in our cohort. AEs were relatively common but not serious.

RESUMEN

INTRODUCTION: North American pit viper envenomation occurs over 4,000 times annually in the United States, with polyvalent Fab antivenom being the primary treatment. Fasciotomy is occasionally performed due to concerns about compartment syndrome. We utilized our direct access to Texas Poison Center Network data to create a new snakebite abstraction form and database on relevant available information between 2004 and 2021 and to identify, describe, and estimate the incidence of fasciotomy following pit viper envenomation in Texas. METHODS: We searched the Texas Poison Center Network database for cases during 2004-2021 using keywords such as fasciotomy, surgery, compartment pressure, and compartment syndrome. Descriptive statistics summarized the data. RESULTS: Of 16,911 reported envenomations, 0.69 percent involved fasciotomies (n = 117). Most common bite sites were digits/hands and lower extremities. Patients who underwent fasciotomy were typically male, aged 20-59, and 10 years younger than the total snakebite population. Only 6 percent of reported compartment syndrome cases had a compartment pressure measurement. Antivenom was administered in 101 (86.3 percent) cases, 92 (91.1 percent) of which received only Fab antivenom product. Patients with bites from rattlesnakes (47.9 percent) were associated with most fasciotomies. DISCUSSION: Our findings suggest a potential increase in snakebite exposures, accompanied by a decrease in fasciotomies. Overall, copperheads constituted the majority of snakebites, but most fasciotomies were from rattlesnake envenomations (47.9 percent). In this cohort, compartment syndrome diagnosis and decisions regarding fasciotomy were primarily based on clinical evaluation/surgeon expertise without compartment pressure measurements. Despite the efficacy of antivenom, only 86.3 percent of patients in our study received antivenom. CONCLUSIONS: Fasciotomy after North American pit viper envenomation in Texas is uncommon (0.69 percent) and has decreased over time, possibly due to increased antivenom use or surgeon comfort with nonsurgical management.

RESUMEN

INTRODUCTION: Exposures to hydrazines occur during aeronautic and space operations and pose a potential risk to personnel. Historically, extensive preparatory countermeasures have been taken due to concern for severe toxicity. This study seeks to better understand manifestations of acute occupational exposures to hydrazine to guide recommendations for management. MATERIALS AND METHODS: A retrospective database review of records from four United States regional poison centers was conducted of all human exposures to hydrazine, monomethylhydrazine, or 1,1-dimethylhydrazine over two decades. Following case abstraction, descriptive statistics were performed to characterize demographics, manifestations, treatments, and outcomes. RESULTS: One hundred and thirty-five cases were identified, and most were adult males exposed to inhaled hydrazine propellant vapors. Fifty-seven percent of patients were asymptomatic following exposure; otherwise, common symptoms were dyspnea, throat irritation, cough, ocular irritation, and headache. All patients were evacuated or received decontamination, with a few reports of symptomatic treatments, including oxygen supplementation and salbutamol (albuterol). Patients usually recovered quickly and were released after a brief healthcare facility evaluation or observed locally. No patients developed delayed symptoms. Symptoms of severe toxicity were not observed, and there were no deaths. DISCUSSION: Acute exposures to hydrazines during operations within the aerospace industry appear to be limited primarily to mucosal and mild pulmonary irritation without significant neurologic, hepatic, or hematologic toxicity. These findings are contrary to previously established expectations and may be related to low-level exposures or possibly due to current emergency countermeasures. CONCLUSIONS: Care in occupational hydrazine exposure will focus on evacuation, decontamination, and symptomatic management of chemical irritant properties of hydrazines. It is reasonable to manage mild cases outside of a healthcare facility. Continued endeavors in human space exploration and habitation will increase the risk of these exposures, making it imperative that clinicians be comfortable with the care and management of these patients.

RESUMEN

We report the case of a 59-year-old military beneficiary that presented to the emergency department after ingesting approximately 90 g of gabapentin immediate-release capsules during a deliberate self-harm attempt. Her serum gabapentin level was 72.8 mcg/mL approximately 3 hours after ingestion. Her renal function panel, complete blood count, and liver function panel were normal. Her urine drug screen, aspirin, ethanol, and acetaminophen level were negative. Her electrocardiogram was normal, including a normal QTc interval. Her only symptoms were nausea and mild sedation. She was admitted for observation with no sequelae noted. She was transferred to a psychiatric facility at that time for further evaluation and treatment. We report a case of gabapentin overdose that presented to the emergency department. Given the large volume ingestion with minimal morbidity, it appears that gabapentin has a wide therapeutic margin and may be safe in overdose.

RESUMEN

OBJECTIVE: Annually, more than 100,000 US and international military and civilian personnel work in Afghanistan within terrain harboring venomous snakes. Current literature insufficiently supports Afghan antivenom treatment and stocking guidelines. We report the clinical course and treatments for snakebite victims presenting to US military hospitals in Afghanistan. METHODS: All snakebite victims presenting to 3 US military emergency departments between July 2010 and August 2011 in northern and southern Afghanistan were examined via chart review. Case information included patient demographics, snake description, bite details and complications, laboratory results, antivenom use and adverse effects, procedures performed, and hospital course. RESULTS: Of 17 cases, median patient age was 20 years (interquartile range [IQR], 12-30), 16 were male, and 82% were Afghans. All bites were to an extremity, and median time to care was 2.8 hours (IQR, 2-5.8). On arrival, 8 had tachycardia and none had hypotension or hypoxia. A viper was implicated in 5 cases. Ten cases received at least 1 dose of polyvalent antivenom, most commonly for coagulopathy, without adverse effects. Six received additional antivenom, 6 had an international normalized ratio (INR) > 10, and none developed delayed coagulopathy. Three received blood transfusions. Hospital stay ranged from 1 to 4 days. None required vasopressors, fasciotomy, or other surgery, and none died. All had resolution of marked coagulopathies and improved swelling and pain on discharge. CONCLUSIONS: We report the largest series of snake envenomations treated by US physicians in Afghanistan. Antivenom was tolerated well with improvement of coagulopathy and symptoms. All patients survived with minimal advanced interventions other than blood transfusion.

RESUMEN

Importance: The US and Canada currently have no formal published nationwide guidelines for specialists in poison information or emergency departments for the management of acetaminophen poisoning, resulting in significant variability in management. Objective: To develop consensus guidelines for the management of acetaminophen poisoning in the US and Canada. Evidence Review: Four clinical toxicology societies (America's Poison Centers, American Academy of Clinical Toxicology, American College of Medical Toxicology, and Canadian Association of Poison Control Centers) selected participants (n = 21). Led by a nonvoting chairperson using a modified Delphi method, the panel created a decision framework and determined the appropriate clinical management of a patient with acetaminophen poisoning. Unique to this effort was the collection of guidelines from most poison centers in addition to systematic collection and review of the medical literature. Comments from review by external organizations were incorporated before the guideline was finalized. The project began in March 2021 and ended in March 2023. Findings: The search retrieved 84 guidelines and 278 publications. The panel developed guidelines for emergency department management of single or repeated ingestion of acetaminophen. In addition, the panel addressed extended-release formulation, high-risk ingestion, coingestion of anticholinergics or opioids, age younger than 6 years, pregnancy, weight greater than 100 kg, and intravenous acetaminophen use. Differences from current US practice include defining acute ingestion as an ingestion presentation from 4 to 24 hours after overdose was initiated. A revised form of the Rumack-Matthew nomogram was developed. The term massive ingestion was replaced with the term high-risk ingestion and denoted by a specific nomogram line. Other recommendations include specific criteria for emergency department triage, laboratory evaluation and monitoring parameters, defining the role of gastrointestinal decontamination, detailed management of acetylcysteine treatment, associated adverse effects, and stopping criteria for acetylcysteine treatment, as well as criteria for consultation with a clinical toxicologist. Finally, specific treatment considerations, including acetylcysteine dosing, fomepizole administration, and considerations for extracorporeal elimination and transplant evaluation, were addressed. Conclusions and Relevance: This qualitative study provides a consensus statement on consistent evidence-based recommendations for medical, pharmacy, and nursing education and practice to optimize care of patients with acetaminophen poisoning.

RESUMEN

OBJECTIVES: Our objective was to assess patients' understanding of emergency department (ED) wait times and why patients may leave the waiting room before seeing a provider. METHODS: Survey of patients in the ED waiting room of an urban tertiary care military hospital where civilian and military patients are treated. RESULTS: A total of 508/517 surveys (98%) were completed. Age ranges were 18 to 35 years (49%), 36 to 60 (31%), or older than 60 (20%). Education levels were high school (20%), some college (37%), or college graduate (39%). Of 503 respondents, 125 (25%) had left an ED waiting room before seeing a provider. The reasons included excessive wait times (91%) and family responsibilities (5%). Five hundred eight reported the factors that would motivate them to wait to see the physician (not leave without being seen [LWOBS]) were the severity of illness (64%), and if they received an update of wait times (26%); 82% (391/480) understood that severely ill patients were seen first. Patients attributed long wait times to doctors and nurses caring for other patients (292/583, 50%) and insufficient physician and nurse staffing (245, 42%). Of 802 responses for ideas to improve the wait, 34% said regular updates on estimated wait times, 21% said television shows or movies to view, 20% said books and magazines to read, and 11% said computers to access. CONCLUSIONS: Long wait times were the primary reason that patients left before seeing a provider, despite having ready access to care. Respondents attributed long wait times to patient volume and inadequate staffing. Regular updates on wait times and material for entertainment may improve the waiting experience and reduce LWOBS.

RESUMEN

Spice is an herbal mixture smoked for euphoria and mixed with synthetic cannabinoids that are undetected on urine drug screens. Spice use has increased in the military because it is considered legal and is not detected on urine drug screen. The authors describe 3 cases of Spice use in military members. Case 1: 19-year-old male presented with paranoia, agitation, and visual hallucinations after smoking the "Space" brand of Spice. Urine thin-layer chromatography (TLC) and gas chromatography-mass spectrometry (GC-MS) were negative. Case 2: 19-year-old female presented with sedation, amnesia, and agitation. She smoked the "Space" brand. She was alert within 3 hours of arrival. Urine GC-MS detected levorphanol. Case 3: 23-year-old male presented with delusions and paranoia. He complained of "monsters on his back." His symptoms improved in the emergency department (ED). His urine TLC and GC-MS were negative. All cases were admitted and evaluated by a toxicologist; all 3 had their history corroborated by family or friends, or with drug paraphernalia. Spice is a new herbal mixture that is increasingly used in the military. Expected effects are similar to cannabis, but may include more paranoia and hallucinations, and may differ for each brand.

RESUMEN

OBJECTIVES: In August 2007, the Food and Drug Administration (FDA) released a public health advisory recommending that over-the-counter cough and cold medications (CCMs) not be used in children younger than 2 years. Our objective was to assess parents' awareness and understanding of the guidelines. METHODS: We surveyed caregivers of children younger than 2 years in the emergency department of an urban tertiary care military hospital where civilian patients are also treated. After completing the survey, caregivers received a handout explaining the FDA's recommendations. RESULTS: Our response rate was 99% (264/265). First-time parents constituted 45% (114/251) of responders. Education level was high school, 21%; some college, 36%; and college graduate, 40%. Thirty-one percent (77/247) were aware of the FDA guidelines. Of these 77, 44 (57%) reported the guidelines indicated CCMs were not safe in children younger than 2 years, and 18 (23%) said CCMs have caused death. Twenty-six percent (68/264) did not give CCMs to their children younger than 2 years, and 40% of these reported it was because of learning about the guidelines; 63% (165/264) reported CCMs were effective, 11% ineffective, and 27% did not know. Fifty-seven percent (151/263) reported CCMs were safe, 12% unsafe, and 31% unsure. Twenty-two percent (31/143) planned to use or continue to use CCMs in their children, 34% did not, 23% not sure, and 21% only if their doctor advised it. CONCLUSIONS: The majority of caregivers were not aware of the FDA guidelines on CCM use in children younger than 2 years. Most thought CCMs were safe and effective.
