Despite recent advances in the knowledge of pain mechanisms and pain management, postoperative pain continues to be a problem. Inadequately managed postsurgical pain has both clinical and economic consequences such as longer recovery times, delayed ambulation, higher incidence of complications, increased length of hospital stay, and potential to develop into chronic pain. Generally, opioids are the mainstay option for pain management in patients with moderate-to-severe postsurgical pain; however, opioids have significant side effects and have abuse potential. ⋯ Utilizing a multi-modal approach may result in a greater reduction in pain vs. single therapies in addition to minimizing opioid use, thus reducing opioid related side effects. However, not all approaches may be effective for all types of patients and not all analgesics may be a viable option for outpatient settings, ambulatory surgery, or the fast-track surgical procedures. In this report, we present a review of the literature with a focus on intranasal ketorolac in order to provide a timely update regarding past, present, and future multi-modal treatment options for postoperative pain.

Randomized Controlled Trial Clinical Trial
The Effect of Methylnaltrexone on the Side Effects of Intrathecal Morphine after Orthopedic Surgery under Spinal Anesthesia.
Methylnaltrexone is a peripheral opioid receptor antagonist that does not cross the blood-brain barrier; so without interference with pain relief, it could reverse the peripheral opioid side effects such as constipation, pruritus, postoperative ileus, and urinary retention. This study has been designed to evaluate the effect of methylnaltrexone on postoperative side effects of intrathecal morphine. In seventy-two 18- to 55-year-old patients scheduled for elective orthopedic operations under spinal anesthesia, neuraxial blockade was achieved using 10 mg 0.5% hyperbaric bupivacaine and 0.1 mg preservative-free morphine sulfate. ⋯ Pain score was significantly lower in group M. Respiratory depression or decreased level of consciousness was not reported in any patient. Subcutaneous administration of methylnaltrexone was not effective in decreasing postoperative urinary retention and pruritus, but lowered the rate of nausea and vomiting and pain score after intrathecal bupivacaine and morphine.

Chest pain frequently prompts emergency medical services (EMS) call-outs. Early management of acute coronary syndrome (ACS) cases is crucial, but there is still controversy over the relevance of pain severity as a diagnostic criterion. ⋯ In our out-of-hospital emergency setting, the severity of chest pain was not a useful diagnostic criterion for AMI.

Prosopagnosia is a rare dysfunction seen during the aura phase of migraine. We aimed to evaluate the face recognition, which has not previously been investigated in migraineurs during the interictal period, and its relationships with clinical features. ⋯ Migraineurs had poorer performance in both face recognition and visuospatial perception. These findings could be based on functional differences in the migraineurs' brain or genetic changes.

Opioid induced depression of sex hormones is a common finding in chronic pain patients receiving long-term opioids by oral, parenteral and even intrathecal routes of administration. The hypothalamic suppression by opioids leads to a hypogonadal state with low testosterone levels in males and subsequent low bone mineral density (BMD). ⋯ Testosterone supplementation was found to largely correct the effects of intrathecal opioids on testosterone levels and BMD.
