Stroke outcome after domiciliary use of opioids in the peri-stroke period.
Stroke affects large number of people worldwide resulting in disability. The people in the northern region of India follow some domiciliary practices, which include administration of opioids at the onset of stroke to retard its progression. ⋯ In this cohort, we found that the domiciliary practice of opioids administration in the peri-stroke period is more common among the elderly and in the rural areas. There was no statistically significant difference in the mean NIHSS and MRS scores at admission as well as discharge implying that the opioid administration did not improve outcome or decrease the severity of the stroke. Our findings are robust enough to propose a larger sample size and follow-up in future studies to definitively ascertain the effect of opioids as pretreatment in stroke patients.

The molecular mechanisms underlying the susceptibility or resilience to trauma-related disorders remain incompletely understood. Opioids modulate emotional learning, but the roles of specific receptors are unclear. Here, we aimed to analyze the contribution of the opioid system to fear responses in two inbred mouse strains exhibiting distinct behavioral phenotypes. ⋯ Blockade of the endogenous opioid system restored freezing behavior in stress-resistant animals. The pharmacological stimulation of the kappa and delta opioid receptors in stress-susceptible individuals may alleviate fear. Thus, subtype-selective opioid receptor agonists may protect against the development of trauma-related disorders.

Hysterosalpingography (HSG) is a method of testing for tubal patency. However, women struggle to tolerate the procedure, as it is associated with some discomfort. Various pharmacological strategies are available that may reduce pain during the procedure, though there is no consensus as to the best method. ⋯ Topical anaesthetic applied before the procedure may be associated with effective pain relief during HSG, though the quality of this evidence is low. Intravenous opioids may also be effective in pain relief, though this must be weighed against their side effects and their effects on the recovery time. There is insufficient evidence to draw conclusions on the efficacy of other analgesics for HSG, or to reach any other conclusions regarding adverse effects.

Transmucosal Immediate-Release Fentanyl for Breakthrough Cancer Pain: Opportunities and Challenges for Use in Palliative Care.
Opioids are used to treat breakthrough cancer pain (BTCP) and can be classified by relative duration and onset of action. Regulatory approvals of numerous transmucosal immediate-release fentanyl (TIRF) formulations provide alternative options to palliative care-trained providers in the management of BTCP. TIRFs have been formulated as a sublingual tablet, sublingual spray, intranasal spray, pectin-based nasal spray, buccal tablet, and buccal soluble film. ⋯ Opportunities for use include palliation of BTCP in head and neck cancer and/or radiation-induced mucositis. The purpose of this review is to discuss TIRF formulation and dosing, pharmacokinetics, clinical efficacy, patient acceptability, and safety/tolerability. In addition, barriers to TIRF utilization will be discussed.
