The Effect of Diphenhydramine on Sleep in Pediatric Burn Patients: A Secondary Analysis
Adequate sleep is essential for maintaining homeostasis, especially when recovering from an illness; however, studies have shown that sleep disruption and sleep deprivation are common in intensive care unit patients, including children who have sustained burn injury. The purpose of this study was to evaluate the effect of diphenhydramine (DPH) on sleep in pediatric intensive care unit burn patients using Myra Levine’s Conservation Model as the organizing framework. For this study, secondary analysis of polysomnography data and retrospective chart review were used. Twelve DPH patients were pair matched in terms of morphin...

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.

Inhibition of cough reflex sensitivity by diphenhydramine during acute viral respiratory tract infection
Conclusions: Our results provide the initial evidence of the ability of diphenhydramine to inhibit cough reflex sensitivity in subjects with acute pathological cough. Timing of cough reflex sensitivity measurement may not have allowed demonstration of maximal antitussive effect of dextromethorphan. (Source: International Journal of Clinical Pharmacy)

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
CONCLUSIONS: The majority of children with migraines are successfully discharged from the ED and only 1 in 18 required a revisit within 3 days. Prochlorperazine appears to be superior to metoclopramide in preventing a revisit, and diphenhydramine use is associated with increased rates of return. (Source: PEDIATRICS)

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.

Modulatory effects of taurine on jejunal contractility.
Abstract Taurine (2-aminoethanesulfonic acid) is widely distributed in animal tissues and has diverse pharmacological effects. However, the role of taurine in modulating smooth muscle contractility is still controversial. We propose that taurine (5-80 mM) can exert bidirectional modulation on the contractility of isolated rat jejunal segments. Different low and high contractile states were induced in isolated jejunal segments of rats to observe the effects of taurine and the associated mechanisms. Taurine induced stimulatory effects on the contractility of isolated rat jejunal segments at 3 different low contractil...

Abstract 5041: The effect of YOCAS(C)(R) Yoga on prescription sleep medication and over-the-counter sleep medication usage in cancer survivors with impaired sleep quality
Background: Impaired sleep quality (ISQ) is highly prevalent among cancer survivors; 30-90% of cancer survivors report some form of ISQ following treatment. Cancer survivors with ISQ are often provided with sleep medications, which fall into two classes: prescription sleep medications (PSM) or over-the-counter sleep medications (OSM). The most common PSM are non-benzodiazepine hypnotics (NBH), benzodiazepines (BENZO), and tricyclic antidepressants (TCA). PSM have an uncertain efficacy, carry a risk of dependency, and may cause deleterious side effects. OSM (usually diphenhydramine and doxylamine) are believed to be safer, ...

1532p * the evaluation of paclitaxel hypersensitivity reactions (hsrs) following the discontinuation of prophylactic pre-medications
Conclusions: In patients receiving paclitaxel+platinum regimens or paclitaxel +/- trastuzumab, the discontinuation of pre-medications is a safe and feasible option if a patient has not experienced an HSR during the first or second dose of paclitaxel.Disclosure: All authors have declared no conflicts of interest.

Symptomatic treatment of the cough in whooping cough.
CONCLUSIONS: There is insufficient evidence to draw conclusions about the effectiveness of interventions for the cough in whooping cough. More high-quality trials are needed to assess the effectiveness of potential antitussive treatments in patients with whooping cough.

A viscous lidocaine mouthwash is no better than placebo for improving oral intake in children with painful mouth ulcers
Commentary on: Hopper SM, McCarthy M, Tancharoen C, et al.. Topical lidocaine to improve oral intake in children with painful infectious mouth ulcers: a blinded, randomized, placebo-controlled trial. Ann Emerg Med 2014;63:292–9. Context Ulcerative oral conditions, infectious (herpetic gingivostomatitis, herpangina, hand, foot and mouth disease) and non-infectious (pharyngitis, gingivostomatitis and aphthous), are often observed in children.1 While most conditions are benign, they can be highly painful, impair food intake, and, more specifically, result in dehydration in young children. Aetiological therapies of viral...

Pre-medications for cetuximab induced infusion reactions – Commentary
We read with great interest the recent work by Touma and colleagues evaluating the role of additional pre-medications to mitigate cetuximab-related hypersensitivity reactions (HSR) [1]. Their results suggest the addition of dexamethasone, albuterol and famotidine to diphenhydramine prior to cetuximab reduces the incidence of overall as well as high-grade HSR. This finding is in agreement with a retrospective analysis of the MABEL trial, which indicated that dexamethasone as a premedication reduced the rate of HSR [2]. (Source: Oral Oncology)

Electrocardiogram attenuation of QRS complexes in association with Takotsubo syndrome
The interesting case report by Rojas-Marte et al. [1], published ahead of print in the Journal on July 31, 2014, about a 31year-old woman who suffered Takotsubo syndrome (TTS), complicated by cardiac arrest and cardiogenic shock, following an overdose of ibuprofen and diphenhydramine, and was treated successfully with extracorporeal membrane oxygenation, provides me with the opportunity to bring to the attention of the authors a newly described association of TTS with early transient electrocardiogram (ECG) attenuation of the QRS complexes (ATTQRS) [2,3].
