To compare the effect of inhaled nitrous oxide (INO) on pain control during in-office hysteroscopy with 1% lidocaine paracervical infiltration and no analgesic.

Single-blind stratified randomised clinical trial with masked assessment by a third party.

Department of Obstetrics and Gynaecology in a Spanish hospital.

Women who underwent hysteroscopy.

Patients were stratified into three groups according to the purpose of the hysteroscopy (biopsy, polypectomy or tubal sterilisation) and then assigned to different treatment groups through a permuted-blocks randomisation within strata. Pain scale was provided by a gynaecologist totally blinded to procedures and treatments. Effects were assessed using a one-way analysis of variance following an intention-to-treat approach.

Visual analogue scale (VAS) from 0 to 100mm.

A total of 314 women were included 105 to INO, 104 to 1% lidocaine and 105 to no analgesic. Baseline characteristics were comparable. Mean VAS score after the procedure was 34.7±25.8mm, 36.1±22.9mm (P=1.0) and 47.3±28.2mm (P=0.001) for INO, 1% lidocaine and no analgesic, respectively. No adverse events were reported in 91 (86.7%) patients in the INO group compared with 79 (76%) in the 1%-lidocaine group (P=0.04) and 85 (81%) in the no-analgesic group (P=0.26).

INO was as effective as 1% lidocaine in pain control for in-office hysteroscopy and was better tolerated. The no-analgesic group presented the poorer results, so was the least recommended clinical option.

Topical corticosteroids are commonly used in the management of allergic otitis externa to diminish inflammation. A common strategy is to make compounded solutions of dexamethasone in ear cleaner.

The objective of this study was to determine the stability of dexamethasone when added to four commercial ear cleaners (ec) designated ecA, ecB, ecC and ecD.

Two concentrations (0.1 and 0.25mg/mL) of dexamethasone were formulated for each cleaner solution from a 2mg/mL solution and stored in the original manufacturers' bottles at two temperatures room (22˚C) and refrigerated (4˚C). Samples were evaluated in triplicate, using liquid chromatography-tandem mass spectrometry at 10 time points over 90days. The mean and standard deviation were calculated for each time point.

A solution was considered stable if the dexamethasone value remained >90% of the target concentration. All dexamethasone solution values were stable to 90 days, except two solutions for ecA; the 0.25 mg/mL dexamethasone concentration was only stable to 14 (4˚C) and 21 days (22˚C).

These results provide preliminary evidence in support of pharmaceutical stability data for dexamethasone when included in the above compounded solutions at the noted concentrations and temperatures.

Here, it was shown that the one-electron reduction of [(o-Ph2 P(C6 H4 )Acr)AuCl]+ (Acr=9-N-methylacridinium) produces a neutral stable radical, the structure of which showed a marked increase in the Au-Acr distance. MSAB purchase Related structural changes were observed for the phosphine oxide analogue [(o-Ph2 P(O)(C6 H4 )Acr]+ , the reduction of which interfered with the P=O→carbenium interaction. These structural effects, driven by a reduction-induced change in the electronic and electrostatic characteristics of the compounds, showed that the charge and accepting properties of the carbenium unit can be modulated. These results highlight the redox-noninnocence of carbenium Z-type ligand, a feature that can be exploited to induce specific conformational changes.
Opioid prescription for chronic noncancer pain is associated with problematic use. We aimed to review and summarize the evidence on the prevalence of problematic use of opioids in adults with chronic noncancer pain and investigate whether the prevalence rates were changing over time.

A systematic review of the literature was undertaken following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. We systematically searched the literature in the electronic databases MEDLINE, SCOPUS, and Web of Science and studies with adult participants with chronic noncancer pain using opioids with indication of one or more of the following terms about problematic opioid use abuse, misuse, addiction, dependence, problematic use, and aberrant behavior/use were eligible for data extraction. Meta-analysis was performed to estimate the pooled prevalence rates using a random-effects model, and subanalysis was conducted.

Our search identified a total of 784 potentially relevant studies. After a thorough evaluation, 19 papers, mostly from the United States, were included in our qualitative and quantitative synthesis. The majority of the data came from speciality pain clinics. The estimated prevalence of problematic use of opioids in adults with chronic noncancer pain was 36.3% (95% confidence interval 27.4 to 45.2%; I
=99.64%). Problematic opioid use was mostly identified using the questionnaire method. Thirteen studies (68%) presented a low risk of bias.

Our study presents an alarming estimate regarding the prevalence of problematic use of opioids among patients with noncancer pain. These results deserve special attention from health care professionals and health authorities.
