The literature, field research, and daily practice stress the need for adequate communication in palliative care. Although language is of the utmost importance in communication, linguistic analysis of end-of-life discussions is scarce. ⋯ Linguistic analysis can help medical professionals to better understand their communicative skills, styles, and approach to patients in end-of-life situations. We have shown how linguistic analysis can contribute to a better understanding of physician-patient interaction. Moreover, we have illustrated the usefulness of interdisciplinary research in the medical domain.

Randomized Controlled Trial Multicenter Study
Efficacy and Safety of Low Dose Subcutaneous Diclofenac in the Management of Acute Pain: A Randomized Double-Blind Trial.
Diclofenac is an effective and well-tolerated nonsteroidal anti-inflammatory drug (NSAID) frequently used in the treatment of acute pain. Marketed formulations for parenteral administration usually contain 75 mg/3 mL of diclofenac sodium, which provide limited dosing flexibility, and are usually given intramuscularly. ⋯ Single SC doses of diclofenac HPβCD of 25 and 50 mg are effective and well tolerated for relieving pain compared with placebo.

Opioids have been used for spinal analgesia for more than a century, and their injection epidurally and intrathecally has a key role in the control of postoperative pain. Since the discovery of the endogenous opioid system, 3 decades ago, their use has become more generalized in obstetric analgesia, the management of chronic pain, and acute postoperative pain. To use opioids effectively for this type of analgesia, it is important to understand the pharmacokinetics and clinical pharmacology of these drugs, specifically those that produce analgesia by an intrinsic spinal mechanism. ⋯ It is more difficult for lipophilic opioids to reach and remain at sufficiently high concentrations at the site of action due to their sequestration in epidural fat and rapid plasma clearance from both epidural and intrathecal spaces, resulting in analgesia with a limited spread and duration, as well as the appearance of early supraspinal side effects. In contrast, morphine has very different properties, including greater spinal bioavailability and therefore administered neuraxially, it is suitable choice for the treatment of acute postoperative pain. However, when using morphine, a greater incidence of adverse effects can be expected, and it requires careful patient selection.

Intrathecal drug delivery (IDD) system with implantable pumps has been used to treat cancer-related pain as well as noncancer-related chronic pain. Opioids, including morphine and hydromorphone, are the most commonly used intrathecal (IT) agents. Although technology, techniques, and knowledge of IDD have improved, dose escalation occurs relatively rapidly in noncancer pain. ⋯ Annual increases in daily opioid dosage were higher among patients with neuropathic pain than among patients with other modalities; we also found no evidence of difference in annual pain reduction.
