RESUMEN
ABSTRACT: Ketamine is a dissociative anesthetic commonly used for procedural sedation owing to its perceived favorable safety profile. Despite its frequent use, overdoses of ketamine are rarely reported, and no cases with serum levels of ketamine or its metabolite have previously been reported. We report a case of an iatrogenic pediatric ketamine 20 mg/kg intramuscular overdose with serial ketamine and norketamine levels that resulted in minimal toxicity.

BACKGROUND: Carboxyhemoglobin (COHb) levels are obtained when there is suspicion for carbon monoxide (CO) exposure. Serial COHb levels are sometimes obtained despite the well-established half-life of COHb with oxygen supplementation. We sought to evaluate the trends and characteristics associated with obtaining serial carboxyhemoglobin levels. METHODS: A retrospective review was performed at an academic medical center for all inpatient and emergency department cases with either single COHb or serial COHb levels from 1 April 2010 through 31 March 2015. Data collected included age, gender, pregnancy status, smoking history, encounter month, admission status, oxygen administration, fire or burn history, vital signs, presenting symptoms, hyperbaric oxygen (HBO2) therapy use, initial pH, troponin, lactate, and COHb levels. The time and change in values between serial levels were also obtained. RESULTS: 624 cases were identified, with 106 (17%) having multiple carboxyhemoglobin levels. A mean of 2.6 (range 2 - 9) serial COHb levels were obtained. The average initial COHb was 8.9%. Subsequent serial levels were obtained on average at 353, 663 and 1,095 minutes and averaged 2.8%, 1.8% and 1.1% respectively. Serial COHb levels were obtained more commonly in burn patients, those admitted to the ICU and those who had HBO2 therapy. Four patients had an increase in COHb level on serial testing. The largest increase of these was from 2.0% to 3.9%. CONCLUSION: Serial COHb levels were not infrequent in this study. No clinically significant increase in COHb was identified by serial testing. Further studies should examine the clinical utility of such practices.

The 2C drugs are hallucinogenic phenethylamines. They and their n-benzyloxymethyl analogs have become popular as "legal highs," and significant toxicity has been attributed to their use. We report on a case of seizures, systemic inflammatory response, and rhabdomyolysis associated with laboratory-confirmed 4-iodo-2,5-dimethoxyphenethylamine and 4-iodo-2,5-dimethoxy-N-(2-methoxybenzyl) phenethylamine exposure. A 17-year-old male teenager developed seizures after taking "2 strips of acid." The seizures resolved with midazolam, but he became apneic and was intubated. His head computed tomography was unremarkable. Initial creatinine level was 1.5 mg/dL, with a creatine kinase of 112 U/L. His urine immunoassay drug screen was negative. He was extubated within 12 hours but had elevated temperatures for 48 hours. He was treated with antibiotics, but no source of infection was identified. His creatinine level peaked at 2.46 mg/dL. His creatine kinase peaked 72 hours later at 14579 U/L. He was treated with intravenous fluids and did not require renal replacement therapy. He recovered fully and was discharged after 5 days. Serum and urine samples were tested using liquid chromatography time-of-flight mass spectrometry. We detected 4-iodo-2,5-dimethoxyphenethylamine and 4-iodo-2,5-dimethoxy-N-(2-methoxybenzyl) phenethylamine in both serum and urine. No other substances were detected. The 2C drugs and their n-benzyloxymethyl analogs are potent serotonergic agents. Their use has been associated with multiple adverse effects including seizures, rhabdomyolysis, and death. They should be considered in differential diagnosis for drug-induced seizures and as a cause for systemic inflammatory response. This case highlights the significant toxicity seen with these compounds.

OBJECTIVE: To characterize pediatric exposures to the antidementia drugs donepezil, memantine, rivastigmine, and galantamine by reviewing a poison control system's database. STUDY DESIGN: A retrospective review of a statewide poison control system's database identified cases of pediatric (less than 19 years of age) exposures to antidementia drugs over an 11-year period. Data collected included age, sex, drug(s) involved, route of exposure, reason for exposure, symptoms, and interventions. RESULTS: There were 189 cases identified (53% male, median age: 2.3 years, 99% unintentional exposures). Donepezil was the most commonly reported exposure (106 cases), followed by memantine (57), galantamine (18), oral rivastigmine (16), and transdermal rivastigmine (3). Coingestants were reported in 68 (36%) cases. Symptoms were reported in 38 (20%) cases. Gastrointestinal symptoms were most common (n = 21) followed by central nervous system depression (n = 15). Oral rivastigmine was associated with higher rates of symptoms. No bradycardia, seizures, or fasciculations were reported. Eighty-nine cases (47%) were evaluated at a health care facility, and 13 (7%) were admitted to a hospital. Oral rivastigmine exposures were associated with increased rate of health care facility evaluation. Activated charcoal was administered in 28 cases. Atropine was given only once, for drooling. There were no serious outcomes or deaths in this series. CONCLUSIONS: Reported pediatric exposures to antidementia drugs resulted in minimal morbidity and no mortality. Oral rivastigmine exposures were found to be associated with more symptoms and health care facility evaluations.

The use of oral antineoplastic agents in nonmedical settings continues to increase. There are limited data available on pediatric exposures to these agents. We sought to identify characteristics of such exposures. We performed a retrospective review of database of a statewide poison system from 2000 to 2009 for all cases of pediatric exposures to oral antineoplastic agents, which took place in a nonmedical setting. Data collected include gender, age, agent of exposure, dose, drug concentration, reason for exposure, symptoms, outcomes, interventions, and length of hospital stay. There were a total of 328 patients. The mean average age was 4.1 years. Eighty-nine percentage (n = 293) was unintentional. Exposures to 21 different antineoplastic agents were identified. Methotrexate (n = 91) and 6-mercaptopurine (n = 47) were the most common agents encountered. Two hundred ninety-nine (91%) cases had no symptoms reported. When reported, gastrointestinal symptoms (n = 17) and central nervous system sedation (n = 6) were most common. One case of pancytopenia was reported. No deaths were reported in this series. Sixty-seven percent (n = 220) were managed at home, whereas 19 (6%) were admitted to a health care facility. Cases were followed by the poison control center for 0.34 days (SD = 1.40). In this study, exposures to oral antineoplastics were primarily unintentional, asymptomatic, and managed at home. Study limitations include possible reporting bias, inability to objectively confirm exposures, and limited duration of monitoring by the poison control center. In this retrospective review, no significant morbidity or mortality was reported from pediatric exposures to oral antineoplastic drugs in the nonmedical setting.

BACKGROUND: Phencyclidine (PCP) use is anecdotally associated with agitation and injury and is frequently tested for in the setting of trauma. We sought to determine characteristics of trauma patients with a PCP-positive urine immunoassay drug screen (UDS) and if they had increased levels of care or mortality. METHODS: A 5-year retrospective review of a level 1 trauma center's trauma registry identified patients with a PCP-positive UDS. This group was then compared with 2 randomly selected control groups from the same trauma registry which were matched for age and sex but differed in that one had no sEtOH detected and a negative UDS (drug-free group) whereas the other had sEtOH or an other-than-PCP-positive UDS (other-drug group). Subgroup analysis was performed comparing PCP-positive patients with undetectable sEtOH with other-drug patients with undetectable sEtOH. RESULTS: The registry contained 7770 patients of which 156 met inclusion criteria. The mean age was 33.4years (range, 19-63), and 77% were male (n=121). When compared with the other-drug group, the PCP-positive group had significantly lower injury severity score, rates of intensive care unit admission, and sEtOH. No difference was seen in vital signs, mechanism of injury, ventilator days, intensive care unit days, total hospital days, disposition, or mortality between the 3 groups. This remained true even when subgroups with negative sEtOH were compared. CONCLUSION: This study suggests that a PCP-positive UDS in the setting of trauma is not associated with increased level of care, length of stay, or mortality.

An 11-year-old boy presented with an antimuscarinic toxidrome due to benztropine and risperidone ingestion. His delirium was prolonged and difficult to treat with benzodiazepines. Multiple doses of physostigmine successfully treated it. Benztropine is a potent antimuscarinic agent, whereas risperidone has not been reported to cause antimuscarinic toxicity. The use of physostigmine to treat benztropine intoxication in a pediatric patient has not previously been described. In this case, multiple doses were used and were well tolerated.

Donepezil and memantine are commonly prescribed antidementia drugs. There is a paucity of literature concerning pediatric ingestions of these drugs. We describe a case of a 2-year-old child who developed encephalopathy after an unintentional ingestion of donepezil and memantine. A 2-year-old girl was found by her family members agitated and reporting visual hallucinations. In the emergency department, she became sedated and had rightward eye deviation. She was hospitalized and had extensive neurological and infectious disease testing that was unremarkable, except for an electroencephalogram, which showed a nonspecific encephalopathy. She recovered with supportive care for 72 hours. Serum concentrations of donepezil and memantine measured on arrival were 470 ng/mL (therapeutic range, 25-50 ng/mL) and 32 ng/mL (therapeutic range, 70-150 ng/mL), respectively. This case demonstrates that unintentional ingestions of memantine and donepezil can potentially cause significant and prolonged neurological symptoms in pediatric patients.

Zolpidem is a widely prescribed anti-insomnia agent. Although most pediatric zolpidem ingestions are benign, large ingestions can cause significant central nervous system (CNS) depression. Flumazenil has been reported to reverse the CNS effects of zolpidem. We describe a case of a large pediatric zolpidem ingestion resulting in profound CNS depression that responded to flumazenil administration. Serial zolpidem serum levels confirmed the ingestion. A 10-year-old boy with trisomy 21 presented to the emergency department 1 hour after he was found sedate with several zolpidem 5-mg tablets in his mouth. Seventeen tables (85 mg) were unaccounted for from a prescription bottle. He became unarousable approximately 2 hours after his ingestion. Flumazenil 0.2 mg intravenously was given with rapid return to his baseline mental status. He became resedate 1 hour later but was arousable. Sixteen hours after his presentation, he was asymptomatic. Serial zolpidem serum levels were obtained, showed an initial level of 310 ng/mL, and demonstrated zero-order kinetics. Zolpidem is an imidazopyridine, which binds to the benzodiazepine receptor. It is rapidly absorbed and has a short-half life. Unintentional pediatric ingestions of zolpidem are typically well tolerated. However, this case demonstrates that large ingestions may cause significant and prolonged CNS depression. Flumazenil, a benzodiazepine receptor antagonist, has been described to reverse the effects of zolpidem in adult ingestions. There are few published reports describing flumazenil use in pediatric ingestion patients. This case suggests that flumazenil may be an effective treatment for zolpidem-induced CNS depression in the pediatric patient.

Introduction: This is the 2021 Annual Report of the Kansas Poison Control Center (KSPCC) at The University of Kansas Health System. The KSPCC serves the state of Kansas 24-hours a day, 365 days a year with certified specialists in poison information and clinical and medical toxicologists. Methods: Encounters reported to the KSPCC from January 1, 2021 through December 31, 2021 were analyzed. Data recorded includes caller demographics, exposure substance, nature and route of exposure, interventions, medical outcome, disposition, and location of care. Results: The KSPCC logged 18,253 total encounters in 2021, including calls from every county in Kansas. A majority of human exposure cases (53.6%) were female. Approximately 59.8% were pediatric exposures (defined as 19 years of age or less). Most encounters occurred at a residence (91.7%) and most were managed there (70.5%). Unintentional exposures were the most common reason for exposures (70.5%). The most common reported substance in pediatric encounters was household cleaning products (n = 815) and cosmetics/personal care products (n = 735). For adult encounters, analgesics (n = 1,241) and sedative/ hypnotics/antipsychotics (n = 1,013) were the most frequently reported. Medical outcomes were 26.0% no effect, 22.4% minor effect, 10.7% moderate effect, and 2.7% major effects. There were 22 deaths. Conclusions: The 2021 KSPCC annual report demonstrated that cases were received from the entire state of Kansas. Pediatric exposures remained most common but cases with serious outcomes continued to increase. This report supported the continued value of the KSPCC to both public and health care providers in the state of Kansas.
RESUMEN
Phencyclidine is one of the drugs of abuse included in qualitative urine drug screens that are frequently ordered in the emergency department despite concerns about specificity and clinical utility. Many drugs have been described to cause false-positive results for phencyclidine. We present 2 cases of false-positive phencyclidine qualitative urine drug screen results in patients with seizures from tramadol misuse or abuse. The involvement of tramadol and its active metabolite, N-desmethyltramadol, was confirmed by in vitro testing. These cases illustrate that tramadol and its metabolites can trigger a false-positive phencyclidine urine drug screen result in nonfatal cases and highlight the lack of specificity of the phencyclidine qualitative urine drug screen.

OBJECTIVES: Rattlesnake envenomations are cited to cause gastrointestinal (GI) symptoms, which may be indicators of systemic envenomation. We sought to identify whether the presence of early GI symptoms, defined as occurring within 4 hours of the bite, could be used to predict antivenom use or bite severity. METHODS: We performed a retrospective review of a statewide poison system's database for all cases of rattlesnake envenomation from January 2000 to December 2009. Data collected included presence of GI symptoms and antivenom use. The GI symptoms were further classified as early (within 4 hours) or late. Bite severity was determined using the minimal to moderate to severe scoring system from collected data. Data were then analyzed with a χ(2) test and Fisher's exact test to evaluate for association between early GI symptoms and either antivenom use or bite severity. RESULTS: There were 2570 reported rattlesnake exposures in the database. Sixty-one (2.4%) of these had GI symptoms reported. Of these, 36 (59%) had symptoms develop within 4 hours of envenomation. A total of 49 patients (80%) received antivenom. Early GI symptoms were seen in 31 (63%) of patients receiving antivenom versus 5 (42%) of patients not receiving antivenom (P = .20). Early GI symptoms were seen in 4 of 6 (66%) of the severe group, 19 of 29 (66%) of the moderate group, and 13 of 26 (50%) of the minimal group (P = .47). CONCLUSIONS: Gastrointestinal symptoms after rattlesnake envenomations were rarely reported in this poison center study, and the presence of early GI symptoms did not predict bite severity or the use of antivenom.

BACKGROUND: The US Food and Drug Administration released a warning related to potential adverse effects related to intentional misuse or abuse ingestions of diphenhydramine in September 2020. We sought to evaluate adolescent-aged (13-19 y) diphenhydramine ingestions reported to US poison control centers to characterize these exposures, adverse effects, outcomes, and trends in outcomes and reasons for ingestion. METHODS: The US National Poison Database System was queried for all exposures to diphenhydramine between January 1, 2007 and December 31, 2020. RESULTS: 47,644 ingestions were included for analysis. An increase in the number of ingestions, percentage of cases due to an intentional reason for ingestion and suspected suicide was observed. More serious outcomes, cardiac complications, seizures, and deaths were more common following intentional ingestions and specifically suspected suicide over misuse or abuse. CONCLUSIONS: Adolescent ingestions of diphenhydramine increased between 2007 and 2020. More serious outcomes, intentional reasons, and suspected suicide also increased over the study interval. Suspected suicide was associated with cardiac complications, seizures, coma, and death at higher rates than misuse or abuse. While misuse and abuse remain a concern, public health interventions focusing on the risk that diphenhydramine pose as an agent of suicide attempt may be of higher impact.

Introduction: This is the 2020 Annual Report of the Kansas Poison Control Center (KSPCC) at The University of Kansas Health System. The KSPCC receives calls from the public, law enforcement, healthcare professionals, and public health agencies. Methods: Encounters reported to the KSPCC from January 1, 2020 through December 31, 2020 were analyzed for caller location, demographics, exposure substance, nature of exposure, route of exposure, interventions, medical outcome, and location of care. Encounters were classified as human or animal exposure, confirmed non-exposure, or information call (no exposure). Results: There were 19,780 total encounters, including 18,492 human exposure cases. These cases were primarily female (53.6%, n = 9,911) and pediatric (19 years of age or less; 59.5%, n = 10,995). Acute cases (82.7%, n = 15,294), unintentional exposures (73.8%, n = 13,643), and ingestions (85.9%, n = 15,901) were most common. The most common reported substance was household cleaning products (n = 937) in pediatric (children ≤ 5) and analgesics (n = 1,335) in adults. An increase in exposures to disinfectants and household cleaning products was seen. Moderate (n = 1,812) or major (n = 482) clinical outcomes were seen in 12.4% of cases. There were 18 deaths in 2020 reported to the KSPCC. Conclusions: Over 18,400 exposures were managed by the KSPCC in 2020. Pediatric exposures remained the most common encounter. An increase in exposures to disinfectants and other household cleaning products was seen. This report supported the continued value of the KSPCC to both public and acute healthcare in the state of Kansas.
RESUMEN
OBJECTIVE: We sought to examine ADHD modified release (MR) and immediate release (IR) stimulant ingestion exposures reported to the National Poison Data System (NPDS) to characterize the nature of the exposures and the outcomes associated with them. METHODS: The NPDS was queried for all single-substance exposures to MR and IR ADHD preparations between January 1, 2007 and December 31, 2017. MR and IR preparations were identified by a generic code of "amphetamine and related compounds" or "methylphenidate" and specific product name containing XR, CD, ER, LA, and SR. RESULTS: A total of 15,796 MR ingestions and 23,418 IR ingestions were identified and followed to known outcome. The majority of ingestions occurred in male patients and in own residence. More serious outcomes (moderate, major, or death) were more common in adult IR and MR ingestions as compared to pediatric; rates of serious outcome increased with age amongst pediatric ingestions. Unintentional ingestions were more common in both MR and IR pediatric cases while intentional ingestions occurred more frequently in adult cases. Symptoms consistent with a hyperadrenergic state were experienced in adult and pediatric patients for both MR and IR ingestions. Supportive care including benzodiazepine administration was more common in IR than MR ingestions. Decontamination with whole bowel irrigation was infrequent. CONCLUSION: Rates of more serious outcome were similar between IR and MR ADHD stimulant ingestions. More serious outcomes were associated with advancing age and intentional ingestions. Similar rates of agitation, tachycardia, and hypertension were experienced by pediatric IR and MR ingestions while more common in adult IR as compared to MR ingestions. Rates of decontamination with whole bowel irrigation were overall low.

BACKGROUND: Medications for opioid use disorder (MOUD) including buprenorphine is recommended for patients with opioid use disorders. We sought to evaluate the frequencies of respiratory depression, intubation, and naloxone administration, and clinical outcomes among patients reported to the National Poison Database System (NPDS) following single-substance and multiple-substance buprenorphine oral exposures. METHODS: NPDS was queried for all MOUD-approved buprenorphine product exposures between 1 January 2003 and 31 December 2019. Data abstracted included year, route, gender, age, site of exposure, management site, medical outcome, recorded "related" respiratory depression ("respiratory rate <10 breaths/min and/or a SpO2 (pulse oximetry)≤90%), reported administration of naloxone and intubation in oral exposure cases followed to known outcome. Concomitant products were also recorded in multiple-substance buprenorphine cases. RESULTS: 27,275 (11,010 multiple and 16,265 single) buprenorphine oral exposures were identified and followed to known outcome. A 65-fold increase in reported cases was reported over the study interval. A steady increase in the frequency of more serious outcomes by year was also observed. Respiratory depression occurred at a frequency of 11.8% (pediatric single-substance), 11.2% (pediatric multiple-substance), 11.3% (adult single-substance), and 11.9% (adult multiple-substance). Among oral exposures of buprenorphine and only one other product, benzodiazepines, opioids, ethanol, and amphetamines were most common. CONCLUSIONS: Oral exposures have increased substantially between 2003 and 2019. More serious outcomes including deaths following oral exposures to buprenorphine have also increased over the same interval for both adult and pediatric patients. Clinically significant rates of respiratory depression in both adult and pediatric patients when taken alone and with additional substances were observed.

INTRODUCTION: There is concern that acute benzodiazepine (BZD) withdrawal may result in morbidity and mortality. However, there is a paucity of medical literature regarding clinical characteristics and outcomes of acute BZD withdrawal. We sought to characterize acute BZD withdrawal and its associated clinical outcomes and treatment at a midwestern academic medical center. METHODS: This was a retrospective study. The medical records of the University of Kansas Hospital, a tertiary academic medical center, were queried for patients with a diagnosis of BZD withdrawal, drug withdrawal, sedative-hypnotic withdrawal, or withdrawal-NOS from January 1, 2009 to January 1, 2016. Data collected included age, sex, month/year of encounter, initial vital signs, type of drug withdrawal (alcohol, opioid, BZD, or other), type of BZD withdrawing from, disposition, duration of hospitalization, seizures, endotracheal intubation, mortality, and pharmacological treatment. RESULTS: Eighty-two cases were identified. Cases per year increased over the study period. Thirty-one (38%) cases involved concurrent drug withdrawal with opioids most common (n = 25). Alprazolam (n = 32) was the most common BZD implicated in BZD withdrawal. Thirty-nine cases (47%) were admitted including seven to the ICU. Seizures were reported in 8 (10%) cases. Endotracheal intubation occurred in three (3.6%). Sixty-seven patients (81%) were treated with a BZD, with lorazepam (n = 42) most used. There were no deaths. Upon discharge, 40 (49%) patients received a prescription for a benzodiazepine. CONCLUSIONS: Cases of acute BZD withdrawal increased over the study period but were associated with only occasional morbidity and no mortality. Further multi-center studies are warranted to characterize the incidence and characteristics of acute BZD withdrawal better.
RESUMEN
INTRODUCTION: This is the 2019 Annual Report of the Kansas Poison Control Center (KSPCC) at The University of Kansas Health System. The KSPCC is one of 55 certified poison control centers in the United States and serves the state of Kansas 24-hours a day, 365 days a year with certified specialists in poison information and clinical and medical toxicologists. The KSPCC receives calls from the public, law enforcement, health care professionals, and public health agencies. All calls to the KSPCC are recorded electronically in the Toxicall® data management system and uploaded in near real-time to the National Poison Data System (NPDS) which is the data repository for all poison control centers in the United States. METHODS: All encounters reported to the KSPCC from January 1, 2019 through December 31, 2019 were analyzed. Data recorded for each exposure includes caller location, age, weight, gender, exposure substance, nature of exposure, route of exposure, interventions, medical outcome, disposition, and location of care. Encounters were classified as human exposure, animal exposure, confirmed non-exposure, or information call (no exposure reported). RESULTS: The KSPCC logged 20,589 total encounters in 2019, including 19,406 human exposure cases. The KSPCC received calls from every county in Kansas. A slim majority of human exposure cases (50.5%, n = 9,790) were female. Approximately 61% (n = 11,876) of human exposures involved a child (defined as 19 years of age or less). Most encounters occurred at a residence (91.6%, n = 17,780) and most cases (64.9%, n = 12,599) originated from a residence. The majority of human exposures (85.5%, n = 16,589) were acute cases (exposures occurring over 8 hours or less). Ingestion was the most common route of exposure documented (85.3%, n = 16,548). The most commonly reported substance in pediatric (children ≤ 5) encounters was cosmetics/personal care products (n = 959) followed closely by household cleaning products (n = 943). For adult encounters, analgesics (n = 1,296) and sedative/hypnotics/antipsychotics (n = 1,084) were the most frequently involved substances. Unintentional exposures were the most common reason for exposures (75.4%, n = 14,634). Most encounters (65.9%, n = 12,780) were managed in a non-healthcare facility (i.e., a residence). Among human exposures, 14,591 involved exposures to pharmaceutical agents while 9,439 involved exposure to non-pharmaceuticals. Medical outcomes were 26.4% (n = 5,116) no effect, 18.8% (n = 3,652) minor effect, 9.3% (n = 1,813) moderate effect, and 3.1% (n = 603) major effects. There were 14 deaths in 2019 reported to the KSPCC. Cases from healthcare facilities and cases with moderate or major medical outcomes increased in 2019 compared to 2018. The number of deaths reported to the KSPCC increased in 2019 to 14 from 7 in 2018. CONCLUSIONS: The results of the 2019 Kansas Poison Control Center's annual report demonstrated that cases were received from the entire state of Kansas totaling over 19,400 human exposures per year. While pediatric exposures remained the most common encounter, there continued a trend of increasing number of cases from healthcare facilities and for cases with serious outcomes. The experience of the KSPCC is comparable to national data. This report supported the continued value of the KSPCC to both public and acute health care in the state of Kansas.
