Overview and Comparison of Interscalene Block Techniques for Brachial Plexus Pain Management.

Purpose Of Review: Peripheral nerve blocks are performed using local anesthetics that are commonly performed prior to surgery to either be the sole anesthetic and/or for postoperative pain management. Interscalene blocks are a specific type of nerve block that targets the superior and middle trunks of the brachial plexus inhibiting transmission of pain signals from the upper extremities to the central nervous system making them useful in mitigating pain following surgeries involving the shoulder, upper arm, and elbow.

Recent Findings: Previously, interscalene blocks were performed with a nerve stimulator, which is an instrument designed to generate a twitch in surrounding muscles to verify the anesthetic block was placed in the correct location.

5 µm CW Ce-doped chalcogenide glass fiber laser with 17% slope efficiency.

Efficient room temperature mid-infrared laser action in a Ce-doped chalcogenide fiber was demonstrated. The fiber had a doped selenide glass core in an undoped sulfide glass cladding. The pump source was a CW Fe:ZnSe laser emitting at 4.

Fake Xanax: Designer Emerging Benzodiazepine Epidemic Linked to Morbidity and Mortality a Narrative Review.

Etizolam is a thienodiazepine derivative which produces an anxiolytic effect similar to benzodiazepines such as alprazolam (Xanax). Like classic benzodiazepines, etizolam has a high affinity towards the GABA receptor, and allosterically potentiates the effects of GABA resulting in neuronal hyperpolarization related to chloride influx. When taken in therapeutic doses, etizolam produces a similar effect to Xanax.

IPACK Block Efficacy for Acute Pain Management after Total Knee Replacement: A Review.

Purpose Of Review: Patients often experience a significant degree of knee pain following total knee replacement (TKR). To alleviate this pain, nerve blocks may be performed such as the adductor canal block (ACB). However, ACBs are unable to relieve pain originating from the posterior region of the knee.

The RU486-dependent activation of the GeneSwitch system in adult muscles leads to severe adverse effects in Drosophila.

Robust genetic systems to control the expression of transgenes in a spatial and temporal manner are a valuable asset for researchers. The GeneSwitch system induced by the drug RU486 has gained widespread use in the Drosophila community. However, some concerns were raised as negative effects were seen depending on the stock, transgene, stage, and tissue under study.
