Direct injection of tissue extracts in liquid chromatography/tandem mass spectrometry for the determination of pharmaceuticals and other contaminants of emerging concern in mollusks.
Abstract In the present study, a straightforward approach was validated for the analysis of pharmaceutically active compounds and endocrine-disrupting chemicals in the mollusk tissues, with a focus on two species commonly consumed in Southeast Asia (green mussels: Perna viridis; lokan clams: Polymesoda expansa). This approach relied on a simple solvent extraction (shaker table) followed by direct injection in liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS). This "cleanup-free" approach was made possible by the use of isotopically labeled surrogates (to correct for matrix effects) and a post-col...

Localized Erythema Multiforme-Like Contact Dermatitis From a Knee Brace
Abstract: A 47-year-old woman developed allergic contact dermatitis (ACD) to a knee brace after anterior cruciate ligament repair, manifesting as numerous erythema multiforme-like lesions. No previous cases of ACD to this Townsend Rebel knee brace, which is commonly worn postoperatively, have been reported. The patient was treated with triamcinolone ointment, cetirizine, and diphenhydramine. On follow-up, the lesions had resolved. We share this case to increase knowledge of this reaction pattern and encourage further similar reports to clarify the nature of the reaction. (Source: Clinical Journal of Sport Medicine)

Sex Differences In over-the-counter sleep aid use in older adults
Over-the-counter (OTC) sleep aids are widely self-administered and are generally safe, but their primary ingredients (diphenhydramine and doxylamine (DPH/DOX)) may pose risks, especially in older adults who may use these products outside of their label recommendations. This analysis characterizes the use of DPH/DOX for sleep disturbances by age and sex in older American adults. (Source: Value in Health)

Investigation of intercalation of diphenhydramine into the interlayer of smectite by XRD, FTIR, TG-DTG analyses and molecular simulation
In this study the intercalation of DPH in the interlayer of a Ca-smectite was characterized by X-ray diffraction, infra-red, and thermogravimetric analyses supported by molecular dynamic simulation. At the low (0.2–0.3 CEC) and high (0.6–0.7 CEC) adsorption levels, the intercalated DPH might take a horizontal monolayer or a bilayer configuration, resulting in a d001 expansion to 15 or 17 Å, respectively. As the amount of DPH intercalation increased, a gradual, yet systematic, dehydration due to removal of hydrated inorganic cation Ca2+ from the interlayer was observed. In addition, the intercalated DPH had a slightly ...

Case Presentation: Trick or Treat?
The Monday morning staff meeting was beginning when a school-aged child and his mother walked up to the glass door. Although the clinic had not opened, upon seeing the child's startling appearance, the four nurse practitioners (NPs) sprang into action. His face was red and severely swollen, his lips were twice normal size, and his eyes were nearly swollen shut (Figure). One NP retrieved the oxygen tank, another reached for the EpiPen, and the third readied the diphenhydramine. The NP at the door talked to the child and assessed his breath sounds.

Ionic Fluids Containing Both Strongly and Weakly Interacting Ions of the Same Charge Have Unique Ionic and Chemical Environments as a Function of Ion Concentration.
Abstract Liquid multi-ion systems made by combining two or more salts can exhibit charge ordering and interactions not found in the parent salts, leading to new sets of properties. This is investigated herein by examining a liquid comprised of a single cation, 1-ethyl-3-methylimidazolium ([C2 mim](+) ), and two anions with different properties, acetate ([OAc](-) ) and bis(trifluoromethylsulfonyl)imide ([NTf2 ](-) ). NMR and IR spectroscopy indicate that the electrostatic interactions are quite different from those in either [C2 mim][OAc] or [C2 mim][NTf2 ]. This is attributed to the ability of [OAc](-) to form comp...

A Comparison of Acute Treatment Regimens for Migraine in the Emergency Department
Migraine headaches are a common presenting complaint in emergency departments. Abortive treatment in this setting is not well studied, leading to considerable variation in treatment. The relationship between acute medications and emergency department revisits has not been studied. Eighty-five percent of children with migraine are successfully discharged from the emergency department; only 1 in 18 children require a return visit. Prochlorperazine is associated with less revisits than metoclopramide, and diphenhydramine use is associated with increased risk of return visits. (Read the full article) (Source: PEDIATRICS)

Show Me the Evidence: Is the Routine Use of Premedication for Transfusion Really Necessary?
Improvements in transfusion medicine, blood typing, and donor screening have reduced the likelihood of a reaction from administration of blood products. In an effort to prevent transfusion reactions, our current standard is to administer acetaminophen 650mg and diphenhydramine 25mg, 30 minutes before transfusions. This practice may unnecessarily place patients at increased risk for complications including falls, cognitive impairment, and hepatic toxicity. (Source: Biology of Blood and Marrow Transplantation)

Honey for acute cough in children.
CONCLUSIONS: Honey may be better than 'no treatment', diphenhydramine and placebo for the symptomatic relief of cough, but it is not better than dextromethorphan. None of the included studies assessed the effect of honey on 'cough duration' because intervention and follow-up were for one night only. There is no strong evidence for or against the use of honey.

In vitro detection of cardiotoxins or neurotoxins affecting ion channels or pumps using beating cardiomyocytes as alternative for animal testing.
Abstract The present study investigated if and to what extent murine stem cell-derived beating cardiomyocytes within embryoid bodies can be used as a broad screening in vitro assay for neurotoxicity testing, replacing for example in vivo tests for marine neurotoxins. Effect of nine model compounds, acting on either the Na(+), K(+), or Ca(2+) channels or the Na(+)/K(+) ATP-ase pump, on the beating was assessed. Diphenhydramine, veratridine, isradipine, verapamil and ouabain induced specific beating arrests that were reversible and none of the concentrations tested induced cytotoxicity. Three K(+) channel blockers, a...

An LC-MS/MS method for the simultaneous determination of lycorine and galanthamine in rat plasma and its application to pharmacokinetic study of Lycoris radiata extract in rats
Summary A rapid, sensitive, and selective liquid chromatography-tandem mass spectrometry was developed for the simultaneous determination of lycorine and galanthamine, two major constituents in Lycoris radiata extract, in rat plasma. Liquid-liquid extraction with ethyl ether was carried out using diphenhydramine as the internal standard. The two bioactive alkaloids were separated on a Zorbax SB-C18 reserved-phase column (150 mm × 4.6 mm, i.d., 5 μm) by gradient elution using a mobile phase consisting of methanol with 0.1% formic acid (A) and water with 0.1% formic acid (B) at a flow rate of 0.6 mL/min. All anal...

The Case Files: The Effects of an Epidural Steroid Injection
This study showed that the duration of absorption of 50 ml of air decreased from 5.8 to 1.9 weeks by 40% FiO2 from 1.9 to 0.6 weeks on room air and 100% FiO2, respectively. (Anesthesiology 1996;84:442.) Several diagnoses should be added to the headache differential diagnosis in the case of a patient receiving recent epidural spinal injections. Post-procedural headache or low-pressure headache, as well as pneumocephalus, should be added to the differential. The patient can be easily placed on a face mask to expedite air resorption, and can be provided symptom control as needed. This patient was successfully manag...
