Randomized Controlled TrialChronic postthoracotomy pain and perioperative ketamine infusion.
The objectives of this study were to investigate whether continuous intravenous ketamine during the first 72 hours after thoracotomy could reduce the incidence and intensity of chronic postthoracotomy pain (CPTP) and to define the incidence and risk factors of CPTP. Seventy-eight patients receiving thoracotomy for lung tumor (benign or malignant) were randomly divided into two groups: ketamine group (n = 31) and control groups (n = 47). Patients in the ketamine group received intravenous ketamine 1 mg/kg before incision, followed by 2 μg/kg/minute infusion for 72 hours plus sufentanil patient-controlled intravenous analgesia after thoracotomy. ⋯ Retractor used time (OR = 5.811, P = .002), inadequate acute pain control (NRS ≥ 5) (OR = 5.425, P = .048), and chemotherapy (OR = 3.784, P = .056) were independent risk factors for chronic postthoracotomy pain. The authors conclude that continuous intravenous ketamine (2 μg/kg/min) during the first 72 hours after thoracotomy was not beneficial to prevent chronic postthoracotomy pain. The independent risk factors for chronic postthoracotomy pain were retractor used time, inadequate acute pain control, and chemotherapy.

Case ReportsAtypical Withdrawal Symptoms after Abrupt Tramadol Discontinuation: A Case Report.
Tramadol is a commonly utilized analgesic in the United States. One common misconception is that tramadol is safer than other opioid medications, or less likely to cause physical dependence. Given these misconceptions, the likelihood of patients experiencing withdrawal after discontinuation may be commonly overlooked as well. ⋯ She reports concerning symptoms of significant mucus production, fullness in chest and soreness in neck. Although tramadol is a Schedule IV Controlled Substance the risk of physical dependence and likelihood of patients experiencing withdrawal symptoms after abrupt cessation should not be diminished. Tramadol should not be considered a "safer" opioid therapy without potential of classic or atypical withdrawal symptoms, as well as risk of abuse, misuse or addiction.

Potential Drug Interactions in Terminally-Ill Cancer Patients, a Report from the Middle East.
This study aims to evaluate the epidemiology of potential drug interactions in terminally-ill cancer patients receiving exclusively supportive care. In this cross-sectional study, during a 6-month follow-up, we considered the medical record of terminally-ill cancer patients referred to palliative care at the cancer center in Isfahan, Iran. Potential drug-drug interactions (DDIs) were assessed by Lexi-Interact ver.1.1 online software. ⋯ The most frequent pharmacological class of drugs responsible for DDIs were quetiapine (91 cases), oxycodone (87 cases), and sertraline (55 cases). Interaction between oxycodone and sertraline was found to be in the top 10 detected DDIs (13.7%). Our results showed that potentially moderate or major drug-drug interactions often occur among terminally-ill cancer patients and the clinical significance of DDIs should be considered meticulously in the palliative care cancer setting.

Nebulized Fentanyl for Dyspnea: A Retrospective Chart Review.
Nebulized fentanyl is well established for analgesia but its use for dyspnea requires further investigation. The aim of our study was to determine the effectiveness of nebulized fentanyl in treating patients with dyspnea and to determine if there were harmful side effects described by patients or their providers. We used a convenience sample of patients from July 1 2014 to July 1 2018 and performed a retrospective chart review. ⋯ Also, 71% of patients with documented responses experienced an improvement in their dyspnea. Our preliminary data suggest that nebulized fentanyl has limited side effects and may have a role in the treatment of dyspnea. Further research is necessary to determine its efficacy.

Case ReportsSuspected Buprenorphine-Precipitated Opioid Withdrawal following Intercourse: A Case Report.
Buprenorphine, a partial mu-opioid receptor agonist, is a commonly prescribed medication for opioid use disorder (OUD). There is evidence that drugs may enter the male genitourinary tract by an ion-trapping process, based on the lipid solubility and degree of ionization (1). ⋯ Limited evidence exists surrounding cervical absorption of drugs via seminal fluid transmission. This also prompts survey of the frequency of this event and the influence on treatment within this population.
