Background And Objectives: Induction of anesthesia is a critical part of anesthesia practice. Sudden hypotension, arrhythmias, and cardiovascular collapse are threatening complications following injection of induction agent in hemodynamically unstable patients. It is desirable to use a safe agent with fewer adverse effects for this purpose. Present prospective randomized study is designed to compare propofol and etomidate for their effect on hemodynamics and various adverse effects on patients in general anesthesia.
Methods: Hundred ASA I and II patients of age group 18-60 years scheduled for elective surgical procedure under general anesthesia were randomly divided into two groups of 50 each receiving propofol (2mg/kg) and etomidate (0.3mg/kg) as an induction agent. Vital parameters at induction, laryngoscopy and thereafter recorded for comparison. Adverse effect viz. pain on injection, apnea and myoclonus were carefully watched.
Results: Demographic variables were comparable in both the groups. Patients in etomidate group showed little change in mean arterial pressure (MAP) and heart rate (HR) compared to propofol (p>0.05) from baseline value. Pain on injection was more in propofol group while myoclonus activity was higher in etomidate group.
Conclusions: This study concludes that etomidate is a better agent for induction than propofol in view of hemodynamic stability and less pain on injection.

Differentially localizing isoforms of the migraine component calcitonin gene-related peptide (CGRP), in the mouse trigeminal ganglion: βCGRP is translated but, unlike αCGRP, not sorted into axons.
J Headache Pain

Sensory Biology Unit, Translational Research Center, Rigshospitalet, Glostrup, Denmark.
Objective: The neuropeptide calcitonin gene-related peptide (CGRP) has been established to be a key signaling molecule in migraine, but little is known about the differences between the two isoforms: αCGRP and βCGRP. Previous studies have been hampered by their close similarity, making the development of specific antibodies nearly impossible. In this study we sought to test the hypothesis that αCGRP and βCGRP localize differently within the neurons of the mouse trigeminal ganglion (TG), using αCGRP knock out (KO) animals.

Background: Facial trauma repair requires precise reconstruction while preserving aesthetic units. Traditional local anesthesia can distort tissue planes and compromise surgical precision.
Methods: This prospective study evaluated landmark-based nerve blocks versus local infiltration for complex facial laceration repair in emergency settings from January 2022 through February 2023.
Dexmedetomidine versus hyaluronidase along with lumbar transforaminal epidural steroid injection in failed back surgery: a randomized double-blind clinical trial.

Background: Failed back surgery syndrome is a common problem faced by chronic pain management specialists. Steroid-only epidural injections have modest efficacy because of excessive scarring. Epidural hyaluronidase (HA), functions as a depolymerizing agent, successfully breaking down adhesions and collagen bundles, whereas dexmedetomidine (DEX) helps to reduce inflammation.

Background: Epidural steroid injections are frequently used to treat chronic radicular pain of a discogenic origin; however, their efficacy remains limited. Magnesium sulfate and dexmedetomidine are emerging adjuvants with the potential to enhance the effectiveness and prolong the therapeutic duration of steroid injections.
Methods: In this randomized, double-blind study, 90 patients with unilateral lower limb radiculopathy due to lumbar disc prolapse who did not respond to conservative treatment for 12 weeks were assigned to three groups.

Department of Anatomy, Cukurova University Faculty of Medicine, Adana, Turkey.
Background: Piriformis syndrome, which is seen as the cause of 0.3% to 6% of low back pain, is a painful condition that occurs as a result of compression of the piriformis muscle on the sciatic nerve. Although there are many studies in the literature about piriformis syndrome, no bibliometric analysis has been found.
