The aim of this study was to determine overall trends and center-level variation in utilization of completion lymph node dissection (CLND) and adjuvant systemic therapy for sentinel lymph node (SLN)-positive melanoma. ⋯ There has been an overall decline in CLND and simultaneous adoption of adjuvant systemic therapy for patients with SLN-positive melanoma though wide variation in practice remains. Accounting for differences in patient mix, location of care contributed significantly to the observed variation.

Randomized Controlled Trial
Adenosine causes short-lasting vasodilation and headache, but not migraine attacks in migraine patients: A randomized clinical trial.
Migraine is a common disabling disease with a complex pathophysiology. Headache is a frequent side effect after intravenous adenosine administration, although adenosine receptor antagonist, caffeine, relieves migraine headache. These observations suggest a possible involvement of adenosine signaling in headache and migraine pathophysiology. ⋯ Adenosine increased heart rate ( P < 0.001), facial skin blood flow ( P < 0.05), and STA diameter (AUC T0-20min , P = 0.01) and decreased V MCA (AUC T0-20min , P < 0.001) compared with placebo. Adenosine induced headache accompanied by a short-lasting (<30 minutes) dilation of intracerebral and extracerebral arteries. The nonsignificant migraine induction might be because of the presence of several adenosine receptors with counteracting signaling, highlighting the need of more selective modulators to dissect the implication of adenosine in migraine.

Referred sensation location can be altered by a strong heterotopic nociceptive stimulus: Implications for clinical pain conditions.
Referred sensations (RS) are a common clinical phenomenon in patients with musculoskeletal pain; however, the underlying mechanisms of RS and implications for diagnosis and management are poorly understood. The location of referral seems to have a preferred site, but studies have suggested it can be redirected to a site of previous injury and pain. However, it is not known if the same phenomenon can occur for a much shorter-lasting painful stimulus in the trigeminal system. ⋯ However, the RS location was displaced on average 1.2 cm between the baseline and postinfusion assessments for the hypertonic saline infusion, which was significantly increased when compared with the isotonic saline infusion which was on average 0.4 cm. These novel findings indicate the potential to modify the location of RS in the trigeminal system following a relatively brief noxious input. Clinicians need to be aware of the possible rerouting of RS in patients with complex orofacial pain.

Balanced Nonopioid General Anesthesia With Lidocaine Is Associated With Lower Postoperative Complications Compared With Balanced Opioid General Anesthesia With Sufentanil for Cardiac Surgery With Cardiopulmonary Bypass: A Propensity Matched Cohort Study.
There are no data on the effect of balanced nonopioid general anesthesia with lidocaine in cardiac surgery with cardiopulmonary bypass. The main study objective was to evaluate the association between nonopioid general balanced anesthesia and the postoperative complications in relation to opioid side effects. ⋯ A balanced nonopioid general anesthesia protocol with lidocaine was associated with lower odds of postoperative complication composite outcome based on respiratory failure and confusion.

The design of the optimal preoperative evaluation is a much debated topic, with the anaesthetist-led in-person evaluation being most widely used. This approach is possibly leading to overuse of a valuable resource, especially in low-risk patients. Without compromising patient safety, we hypothesised that not all patients would require this type of elaborate evaluation. ⋯ A number of alternatives to the anaesthetists-led in-person preoperative evaluation have already been researched: that is telephone evaluation, telemedicine evaluation, evaluation by questionnaire and nurse-led evaluation. However, more high-quality research is needed to assess viability in terms of intraoperative or early postoperative complications, surgical cancellation, costs, and patient satisfaction in the form of Patient-Reported Outcome Measures and Patient-Reported Experience Measures.
