Botulinum Toxin A Salvage of Ischemic Hand Trauma

Summary: Posttraumatic hand injuries from crush injury, infusion, or iatrogenic vascular cannulation can cause ischemic finger damage that can progress to necrosis and digital amputation. Botulinum toxin type A (Botox) improves blood flow in chronic vasospastic disorders of the hand. Botox’s efficacy in salvaging ischemic loss in digits in acute traumatic and iatrogenic injury has not been previously reported. From February of 2015 to December of 2016, 11 patients at a Level I trauma center (West Virginia University) presented to the hand surgery service with early ischemic injury and vascular compromise to hand and fingers as a result of crush, direct drug injection, or proximal arterial injury from drug injection or catheterization. Before 2015, all patients with vascular compromise were treated with standard protocol. After January of 2016, patients were treated with additional injection of 80 to 100 U of Botox into the palm and wrist. Before administration of Botox, six patients with vascular compromise of one or more fingers were treated with a conservative protocol and 83 percent had amputation of necrotic digits. After January of 2016, five patients with ischemia were treated with Botox into the palm and proximal arteries. All Botox-treated digits were preserved (100 percent salvage). Pain scores were lower in Botox-treated fingers. We conclude that (1) in the acute traumatic vascular hand injury, early Botox injection markedly increases digital salvage; (2) di...

AbstractPurpose of ReviewAnkle sprains are a common injury that can lead to chronic lateral ankle instability resulting in pain, poor function, and decreased quality of life. The purpose of this review is to present information regarding injury mechanisms to the lateral ligaments of the ankle and the necessary steps to appropriately diagnose lateral ligament instability.Recent FindingsThe literature demonstrates that history and physical examination is often a reliable method for diagnosis of lateral ankle instability. In addition, imaging modalities are often used as adjuncts for diagnosis, especially when physical exam f...

CONCLUSIONS: Our findings suggest that the origins of the early-onset CS require serious investigation. Research into the potential to reduce future chronic pain conditions through early effective treatment of primary dysmenorrhea is also needed. PMID: 32475703 [PubMed - as supplied by publisher]

​Emergency providers expeditiously sift and sort patients on their shifts and streamline procedures like how to place an ear wick in a patient with otitis externa, a quick and useful procedure for a patient who will reap the rewards.Standard ear wicks. The material is made from a dehydrated sponge composed of hydroxylated poly(vinyl acetate). It increases in size when liquid is applied. Photo by M. Roberts.Otitis externa can cause significant swelling, irritation, pruritis, and pain to the ear canal. Occasionally, the canal is so swollen it may be difficult to administer ear drops. An ear wick can be inserted between the...

To the Editor In the ESCAPE randomized clinical trial, Dr Issa and colleagues concluded that early surgery compared with an endoscopy-first approach resulted in significantly less pain over 18 months among patients with chronic pancreatitis. We are concerned about the generalizability of the finding.

AbstractThe use of cocaine constitutes a major health problem. Cocaine use is associated with acute and chronic complications that might involve any system, the most common being the cardiovascular system. The precise incidence of cocaine-induced cardiomyopathy remains mysterious and probably underreported. Cocaine use should be considered in young patients presenting with chest pain or heart failure without other underlying risk factors. Cocaine-related cardiovascular complications can be acute or chronic and include ischemic and non-ischemic events. Frequent cocaine users have a seven-fold higher risk of myocardial infar...
