BACKGROUND: We aimed to evaluate the effect of doxylamine, a first generation antihistamine, as a local analgesic agent by comparing its effect to bupivacaine. METHODS: After blocking the cutaneous trunci muscle reflex (CTMR) by subcutaneous injection of doxylamine, we assessed doxylamine's cutaneous analgesic effect in rats. The dose-related effect and duration of doxylamine on infiltrative cutaneous analgesia were compared with that of bupivacaine. RESULTS: We demonstrated that doxylamine, as well as the local anesthetic bupivacaine produced the cutaneous analgesic effects in a dose-related fashion...

Interferon-beta (IFNβ) are effective treatments for relapsing multiple sclerosis. IFNβ treatment includes subcutaneous (sc) IFNβ-1b, intramuscular and sc IFNβ-1a, and sc pegylated IFNβ-1a (PEG-IFNβ-1a). PEG-IFNβ-1a offers the advantage of a prolonged duration of action with a less frequent administration (every 2 weeks) and a higher patient adherence. However, the use of subcutaneous interferons could be characterized by potential skin toxicity. Injection site reactions (ISRs), featured by erythema, edema, pain and pruritus, are the most common adverse reactions...

As a new generation of amide-type local anesthetics (LAs), ropivacaine has been widely used for pain management in clinical settings. Increasing evidence has shown that administration of ropivacaine causes cytotoxic effects and apoptosis. However, the underlying molecular mechanisms still need to be elucidated. In the current study, our results indicated that ropivacaine treatment caused a significant induction of heme oxygenase-1 (HO-1) at both the mRNA and protein levels in human SHSY5Y cells. Levels of HO-1 mRNA and protein peaked at 1 h and 18 h, respectively, in response to ropivacaine treatment...

BACKGROUND: Anaphylaxis-like reactions occur within minutes after application of local anesthetics (LA), most commonly during dental interventions. Impressive symptoms including respiratory distress or loss of consciousness frequently give rise to a suspicion of allergy and may prompt patients and treating physicians to refuse future LA injections. OBJECTIVE: Non-allergic mechanisms are responsible for the majority of LA-induced immediate-type reactions. In view of the preponderance of non-allergic reactions, the question arises whether genuine LA allergy may be missed during routine testing procedures...

Simultaneous recording of optical and electrophysiological signals from multiple cortical areas may provide crucial information to expand our understanding of cortical function. However, the insertion of multiple electrodes into the brain may compromise optical imaging by both restricting the field of view and interfering with the approaches used to stabilize the specimen. Existing methods that combine electrophysiological recording and optical imaging in vivo implement either multiple surface electrodes, silicon probes, or a single electrode for deeper recordings...

Renal tubular acidosis (RTA) with hypokalemia may precipitate acute respiratory failure and potentially fatal arrhythmias like ventricular fibrillation. Though there are random reports of respiratory failure needing mechanical ventilation and sudden death in patients with RTA and hypokalemia, the anesthetic management of these patients has not been clearly elucidated. Acidosis and hypokalemia have significant interactions with both general and local anesthetics and alter their effect substantially. Proper preoperative planning and optimization are required for the safe conduct of anesthesia in this subset of patients...
