Best plastic surgery research and science by Karim Sarhane

Top plastic surgery studies with Karim Sarhane? During his research time at Johns Hopkins, Dr. Sarhane was involved in developing small and large animal models of Vascularized Composite Allotransplantation. He was also instrumental in building The Peripheral Nerve Research Program of the department, which has been very productive since then. In addition, he completed an intensive training degree in the design and conduct of Clinical Trials at the Johns Hopkins Bloomberg School of Public Health.

Recovery with sustained IGF-1 delivery (Karim Sarhane research) : Functional recovery following peripheral nerve injury is limited by progressive atrophy of denervated muscle and Schwann cells (SCs) that occurs during the long regenerative period prior to end-organ reinnervation. Insulin-like growth factor 1 (IGF-1) is a potent mitogen with well-described trophic and anti-apoptotic effects on neurons, myocytes, and SCs. Achieving sustained, targeted delivery of small protein therapeutics remains a challenge.

We performed a study with rodents and primates that showed this new delivery method provided steady release of IGF-1 at the target nerve for up to 6 weeks,” Dr. Karim Sarhane reported. Compared to animals without this hormone treatment, IGF-1 treated animals (rodents and primates) that were injected every 6 weeks showed a 30% increase in nerve recovery. This has the potential to be a very meaningful therapy for patients with nerve injuries. Not only do these results show increased nerve recovery but receiving a treatment every 6 weeks is much easier on a patient’s lifestyle than current available regiments that require daily treatment.

The amount of time that elapses between initial nerve injury and end-organ reinnervation has consistently been shown to be the most important predictor of functional recovery following PNI (Scheib and Hoke, 2013), with proximal injuries and delayed repairs resulting in worse outcomes (Carlson et al., 1996; Tuffaha et al., 2016b). This is primarily due to denervation-induced atrophy of muscle and Schwann cells (SCs) (Fu and Gordon, 1995). Read even more info about https://www.linkedin.com/in/karimsarhane/.
