    ABSTRACT: Hong SB, Kim HJ, Huh JW, et al.: A cluster of lung injury associated with home humidifier use: clinical, radiological and pathological description of a new syndrome. Thorax 2014; 69: 694–702.Background: This case series described a cluster of previously healthy adults who were admitted to a Korean intensive care unit for severe respiratory distress. All cases occurred over a several month period in 2011, some of which progressed to death. In-depth diagnostic testing did not reveal an infectious etiology.Research Question: The goal of the authors, along with the Korean Centers for Disease Control, was to investigate the cause of respiratory disease in a cluster of previously healthy patients.Methods: A multidisciplinary team, developed and chaired by the authors, was established to review the clinical features, laboratory, radiographic, and pathology findings for all cases. This team included pulmonologists, radiologists, and pathologists. A case was retrospectively defined as any patie ...

    ABSTRACT: The anticholinergic toxidrome is well described and relatively common. Despite controversy, studies have shown that physostigmine is relatively safe and effective in reversing this toxidrome. We would expect toxicologists would be liberal in its use. We retrospectively analyzed data in the Toxicology Investigators Consortium (ToxIC) registry, representing data from medical toxicologists in multiple institutions nationwide, searching for patients who exhibited an anticholinergic toxidrome, determining what treatment(s) they received, and classifying the treatments as physostigmine, benzodiazepines, physostigmine and benzodiazepines, antipsychotics, or no definitive treatment. The causal agents of the toxidrome were as reported by the treating toxicologist. Eight hundred fifteen consecutive patients with anticholinergic toxidromes were analyzed. Benzodiazepines alone were given in 28.7 %, 12.4 % were given physostigmine alone, 8.8 % received both physostigmine and benzodiazepines, 2.7 % were given antipsychotics, and 47.4 % were given no definitive treatment. In patients who received only physostigmine, there was a significant difference in the rate of intubation (1.9 vs. 8.4 %, OR 0.21, 95 % CI 0.05-0.87) versus other treatment groups. Physostigmine was given at varying rates based on causative agent with use in agents with mixed or unknown effects (15.1 %) being significantly lower than those with primarily anticholinergic effects (26.6 %) (p < 0.001). Patients with anticholinergic toxicity were more likely to receive benzodiazepines than physostigmine. Those patients who received only physostigmine had a significantly lower rate of intubation. Physostigmine was more likely to be used with agents exerting primarily anticholinergic toxicity than in those agents with multiple actions.

    ABSTRACT: Chronic pain is a common reason for emergency department (ED) visits. Our objective was to describe opioid prescribing practices of ED providers when treating patients with chronic pain. We retrospectively evaluated opioid prescriptions from EDs at two tertiary care military hospitals. We queried the outpatient record database to obtain a list of opioid medications prescribed and ICD-9 codes associated with visits for chronic pain. We collected provider type and gender, number of pills, opioid type, and refills. We compared the incidence with chi-square or Fisher's exact tests. Wilcoxon test was used for non-parametric continuous variables. Over 3 years, 28,103 visits generated an opioid prescription. One thousand three hundred twenty-two visits were associated with chronic pain, and 443 (33 %) visits were associated with an opioid prescription. Providers were 79 % physicians, 19 % physician assistants (PAs), 81 % male, and 69 % active duty military. Medications were 43 % oxycodone, 30 % hydrocodone, 9.5 % tramadol, 2.5 % codeine, and 15 % other. The number of pills was 20 [interquartile range (IQR) 15-30] (range 1-240), morphine equivalents (M.E.) per pill was 7.5 [7.5-7.5] (2.5-120) and total M.E. per prescription was 150 [112.5-270] (15-6000). Physicians were more likely to prescribe a non-opioid than PAs (77 vs 45 %, p < 0.0001). Civilian providers were more likely to prescribe an opioid than active duty providers (58 vs 42 %, p < 0.0001). Providers prescribed a median of 20 pills per prescription and most commonly prescribed oxycodone. PAs were more likely to prescribe an opioid for chronic pain than physicians. Civilian providers were more likely to prescribe an opioid than active duty providers.

    ABSTRACT: Carpet vipers (Echis) are found across the semiarid regions of west, north, and east Africa; west, south, and east Arabia; parts of Iran and Afghanistan north to Uzbekistan; and in Pakistan, India, and Sri Lanka. Recently, a new species belonging to the Echis genus, Echis omanensis has been recognized in Oman. Not much is known about the clinical manifestations of envenomation from its bite. A 63-year-old snake keeper presented to the emergency department shortly after being bitten by an Oman carpet viper (E. omanensis). The incident occurred during expression of the venom at a research center. The patient complained of severe pain and swelling of the left index finger, which extended to the mid-forearm within 1 h. His vital signs remained stable, with no evidence of systemic manifestations. He was treated initially with analgesics and tetanus toxoid. Due to rapidly progressive swelling and the potential for a delayed coagulopathy, the Saudi National Guard polyvalent snake antivenom was administered according to the Ministry of Health protocol. The patient was admitted to the intensive care unit, remained hemodynamically stable, and had normal serial coagulation tests, with subsequent resolution of the swelling. We report the first case of an E. omanensis bite in which the patient developed rapidly progressive local toxicity, which improved after administration of the Saudi polyvalent antivenom.

    ABSTRACT: The NBOMes (N-benzyl-oxy-methyl derivatives of known 2C phenylethylamines) are a new and growing class of potent synthetic stimulants. Case reports provide the bulk of available safety and clinical data for clinicians. We report two cases of NBOMe intoxication with 25C-NBOMe (the first lab-confirmed US case) and 25B-NBOMe, respectively, both confirmed via triple quadrapole mass spectrometry.

    ABSTRACT: Elevated concentrations of serum acetaminophen-protein adducts, measured as protein-derived acetaminophen-cysteine (APAP-CYS), have been used to support a diagnosis of APAP-induced liver injury when histories and APAP levels are unhelpful. Adducts have been reported to undergo first-order elimination, with a terminal half-life of about 1.6 days. We wondered whether renal failure would affect APAP-CYS elimination half-life and whether continuous venovenous hemodiafiltration (CVVHDF), commonly used in liver failure patients, would remove adducts to lower their serum concentrations. Terminal elimination half-lives of serum APAP-CYS were compared between subjects with and without renal failure in a prospective cohort study of 168 adults who had ingested excessive doses of APAP. APAP-CYS concentrations were measured in plasma ultrafiltrate during CVVHDF at times of elevated serum adduct concentrations. Paired samples of urine and serum APAP-CYS concentrations were examined to help understand the potential importance of urinary elimination of serum adducts. APAP-CYS elimination half-life was longer in 15 renal failure subjects than in 28 subjects with normal renal function (41.3 ± 2.2 h versus 26.8 ± 1.1 h [mean ± SEM], respectively, p < 0.001). CVVHDF failed to remove detectable amounts of APAP-CYS in any of the nine subjects studied. Sixty-eight percent of 557 urine samples from 168 subjects contained no detectable APAP-CYS, despite levels in serum up to 16.99 μM. Terminal elimination half-life of serum APAP-CYS was prolonged in patients with renal failure for reasons unrelated to renal urinary adduct elimination, and consideration of prolonged elimination needs to be considered if attempting back-extrapolation of adduct concentrations. CVVHDF did not remove detectable APAP-CYS, suggesting approximate APAP-protein adduct molecular weights ≥ 50,000 Da. The presence of urinary APAP-CYS in the minority of instances was most compatible with renal adduct production and protein shedding into urine rather than elimination of serum adducts.

    ABSTRACT: Oleander poisoning typically results in cardiac arrhythmias, hyperkalemia, and gastrointestinal irritation, and can be fatal. Oleander extracts have also been studied experimentally as hypoglycemic agents. Here, we describe a dog with confirmed oleander toxicosis presenting with classical symptoms and also hypoglycemia. After excluding other likely causes of hypoglycemia, the finding was attributed to oleander toxicosis, which has not been previously reported in dogs. A 7-year-old female spayed Maltese was presented to the emergency service after ingesting oleander leaves. Toxicosis was confirmed by measurement of digoxin using a competitive binding immunoassay, patient level 0.7 ng/mL (0.9 nmol/L) 24-h post-ingestion. Clinical symptoms included vomiting, cardiac arrhythmia, mild hyperkalemia, and hypoglycemia. Treatment was successful with aggressive supportive care, and the dog was discharged from the hospital after 48 h and made a full recovery. This case reviews the presentation and treatment of oleander toxicity but also highlights possible effects of oleander on blood sugar in dogs. Hypoglycemia in this dog, attributed to oleander poisoning, is interesting as it supports experimental research into hypoglycemic properties of oleander extracts.
