My medical student Clare Teng put together this great review article and even better video review of our experience with near infrared fluorophore visualization of #braintumor with #icg. #litbrain #brainsurgery

I am excited that Kati Kariko and Dr. Weissman who patented the mRNA vaccine technology were able to receive their vaccines Penn Medicine. I am still amazed that Kati Kariko was a PhD @PennNSG!

Interview season has begun! We are training the best and brightest! @PennNSG #litbrain

Thanks to @nasbs_org for sharing my work. #litbrain #endoscope @pennnsgy

Size alone does not predict hearing loss in acoustic neuroma. I applaud Mass Eye and Ear Dr Stankovic for this pioneering finding that perhaps protease are responsible for ototoxicity of these tumors.

"These findings indicate that nucleoside modification is an effective approach to enhance stability and translational capacity of mRNA while diminishing its immunogenicity in vivo. Improved properties conferred by pseudouridine make such mRNA a promising tool for both gene replacement and vaccination." And so the field of mRNA vaccines was born -- Neurosurgery basic research scientist @kkariko

#trigeminalneuralgia #facialpain aka #suicidepain can be cured with fully #endoscopic #microvascular decompression with less postoperative headache than conventional open surgery. #mvd can also cure #hemifacial spasm. Surgery by John Y.K. Lee, MD, MSCE. Procedure Invented by Peter Jannetta, MD.

Great resource. @PennNSG Rachel Blue, Stephen Miranda, H. Isaac Chen and medical student Ben Gu

#hemifacialspasm starts as an innocuous wink but spreads to the lower face and then closes the eye ultimately disfiguring the face. Botox is a poison which paralyzes the muscles but is not a cure. Microvascular decompression (Jannetta procedure) #brainsurgery can cure the cause of the problem. Fully #endoscopic #mvd provides fantastic visualization and is employed by master surgeons. #litbrain

Friday November 6, 2020. Intraoperative Molecular Imaging Fluorescent Guided Surgery - Penn CME course - virtual. Free for students and trainees. #litbrain

Beautiful day to serve as unaffiliated neuro trauma #concussjon consultant for the @NFL in a largely empty stadium. I was impressed by the amount of work NFL has done to keep players and staff safe with lots of #covid19 testing, #masks, #socialdistancing.

I thoroughly enjoyed the opportunity to present our research on near infrared fluorophores for #braintumor #brainsurgery. Thanks to @michaelivanmd and University of Miami Neurosurgery and panelists #litbrain https://youtu.be/8I9ydq4FMVY

Congratulations to superstar medical student for her paper combining icg and pdt using nanoparticles to treat glioblastoma! #litbrain #braintumor #brainsurgery @thecbearsuite

Driving from Pittsburgh to Philadelphia after lecturing at UPMC, I stopped by the Flight 93 National Museum to honor the courage of those who fought terrorists in the cabin of airplane, saving countless lives but at their own expense. #911 #neverforget #September11

Brain Tumor Surgeons delicately dissect normal vasculature, slippery tumors, and silky smooth eloquent cortex -- all while the patient is awake and talking! #awakecraniotomy #insular glioma #braintumor #brainsurgery @PennNSG #sylvianfissure #litbrain Awake Craniotomy. Patient talks throughout surgery in order to preserve language function. Tumor is delicately dissected from vasculature and normal anatomy.

Congratulations to Steve Cho, MD, MTR who graduates from Perelman school of medicine to join the illustrious Barrow Neurological Institute Neurosurgery training program! I have all confidence he will create a bright future for the field and patients. #litbrain @ Philadelphia, Pennsylvania

Congratulations to Steve Cho, MD, MTR who graduates Perelman school of medicine today and will start Barrow Neurological Institute Neurosurgery residency! I have all the confidence that he will create a brighter future for our field and our patients. #litbrain

I am very excited that patients with #acousticneuroma #brainsurgery #gammaknife will have an opportunity to share their experience, concerns, frustrations, successes at this Virtual Support Group - Philadelphia chapter of the Acoustic Neuroma Association. Special Thanks to Marya Camilleri who is leading the Philadelphia effort a well as Denise Miller, Meneske Silpagar and many others. http://campaign.r20.constantcontact.com/render
