Goldfrank Show Notes Graduation 2020 Lewis R. Goldfrank, MD June 17, 2020 WELCOME TO THE GRADUATES Congratulations to a wonderful group of physicians. It is a pleasure to recognize your great accomplishments in the presence of your friends, families, loved ones and the residents and faculty who have learned so much from and with you. I would first like to recognize those of you who are members of the Gold Humanism Honor Society. There are a remarkable number of awardees in our graduating class of 2020. CLASS OF 2020 Joe Bennett (R) Max Berger (R) Ashley Miller (R) Leigh Nesheiwat (S) Kristen Ng (R) Emily Unks (S) AND Arie Francis (R) Nisha Narayanan (S) FUTURE PGY-4 Elena Dimiceli (S) Kamini Doobay (S) Mark Iscoe (R) FUTURE PGY-3 Stasha O’Callaghan (S) Nicholus Warstadt (S) FUTURE PGY-1 Aaron Bola (S) Alison (Ali) Graebner (S) Aron Siegelson (S) Melissa Socarras (S) Sarah Spiegel (S) Thomas Sullivan (S) Christy Williams (S) GOLD HUMANISM CORE VALUES Integrity, Excellence, Compassion, Altruism, Respect, Empathy, Service These are the values you want as a doctor for yourself or a loved one, * to have outstanding listening skills with patients * to be at your side during a medical emergency, * to have exceptional interest in service to the community, * to have the highest standards of professionalism * to integrate a humanistic approach in patient care. These values are what brought all of you to NYU-Bellevue and that you have honed throughout your training. The remainder of this talk shows how all of you have been successful and demonstrated these values some of you were elected to the Gold Humanism—all of you have achieved humanistic success. Your personal efforts in the face of uncertainty of the evolution of the pandemic, the inadequate supplies, the hospital and governmental problematic decisions are remarkable. In our country, the President did not mourn the loss of more than a 100,000 human beings and the needs of society. Nor did he provide the leadership and moral support that the country desperately needed to optimally handle this unprecedented crisis. You, in contrast, demonstrate unflappable commitment to address and overcome obstacles to care for your patients, assist your peers, educate and care for your families and friends, while also caring for yourselves. This is a tribute to your humanism. You created essential ways to help patients who were isolated from families and friends during the critical phases of COVID-19.

Episode 171.0 – Vaping Associated Lung Injury
An overview of Vaping Associated Lung Injury (VALI) Hosts: Audrey Bree Tse, MD Larissa Laskowski, DO Brian Gilberti, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/Vaping_Associated_Lung_Injury.mp3 Download 2 Comments Tags: Pulmonary, Toxicology Show Notes Why this matters As of Oct 15, vaping has been associated with acute lung injury in over 1400 people 33 deaths have been confirmed in 24 states 70+% of those with VALI are young men A large number of patients are requiring ICU/ intubation/ ECMO 4 main ingredients in solvent +/- Flavor additives +/- Nicotine or THC (Tetrahydrocannabinol) Propylene Glycol (PG) Vegetable Glycerin (VG) CDC definition of VALI (Vaping Associated Lung Injury) Using an e-cigarette (“vaping”) or dabbing* in 90 days prior to symptom onset AND Pulmonary infiltrate, such as opacities, on plain film chest radiograph or ground-glass opacities on chest CT AND Absence of pulmonary infection on initial work-up.  No evidence in the medical record of alternative plausible diagnoses (e.g., cardiac, rheumatologic, or neoplastic process). *Dabbing allows the user to ingest a high concentration of THC.  Butane Hash Oil (BHO), an oil or wax-like substance extracted from the marijuana plant, is placed on a “nail” attached to a specialized glass bong called a “rig.” A blow torch is used to heat the wax, which produces a vapor that can then be inhaled to supposedly produce an instantaneous effect. Pathophysiology At present, no single compound or ingredient has emerged as the cause, and there may be more than one cause The only common thread among the cases is that ALL patients reported using e-cig or vaping products Leading potential toxins: Vaping products containing THC concentrates: most cases are linked to THC concentrates that were either purchased on the street or from other informal sources (meaning not from a dispensary) Vitamin E acetate: nutritional supplement safe when ingested or applied to the skin (but likely not when inhaled) has been found in nearly all product samples of NY state cases of suspected VALI vitamin E acetate is NOT an approved additive at least by NYS Medical Marijuana program Other potential toxins: IT CANNOT BE UNDERSTATED that a small percentage of persons w/ VALI have reported exclusive use of nicotine-containing vape products, such as JUUL; as such, we must consider the potential toxicity of standard e-liquid or vape juice Flavor additives, that exists as chemical aldehydes: irritating and potentially damaging to lung tissue PG/VG: shown not only to break down to formaldehyde which is a known carcinogen,

Episode 170.0 – Septic Arthritis
An overview of septic arthritis. Hosts: Audrey Bree Tse, MD Brian Gilberti, MD https://media.blubrry.com/coreem/content.blubrry.com/coreem/Septic_Arthritis.mp3 Download One Comment Tags: Infectious Diseases, Orthopedics Show Notes Episode Produced by Audrey Bree Tse, MD Background Bacteria enters the joint by hematogenous spread due to absence of basement membrane in synovial space from invasive procedures, contiguous infection (e.g. osteomyelitis, cellulitis), or direct inoculation (e.g. plant thorns, nails) WBCs migrate into joint → acute inflammatory process → synovial hyperplasia, prevents new cartilage from forming, pressure necrosis on surrounding joint, purulent effusion Why do we care?  irreversible loss of function in up to 10% & mortality rate as high as 11% Cartilage destruction can occur in a matter of hours Complications include bacteremia, sepsis, and endocarditis Etiology Risk factors: extremes of age, RA, DJD, IVDA, endocarditis, GC, immunosuppression, trauma, or prosthesis Organisms:  Staph: staph aureus (most common), MRSA, Staph epidermis N gonorrhea: young healthy sexually active adults Strep: group A & B GNRs: IVDA, diabetics, elderly Salmonella: sickle cell disease Cutibacterium acnes: prosthetic shoulder infection Consider mycobacterial & fungal in more indolent courses Presentation Typically a single, warm, erythematous, tender joint (#1: knee (50% of cases) → hip, shoulder, ankle) *Any joint can be involved! IVDA can involve sacroiliac, costochondral, & sternoclavicular joints  Classic teaching: very painful with ROM, but this is not always present! Joint usually held in position of maximum joint volume Prosthetic joints may have less pain than expected for a septic joint given changed anatomy and disrupted nerve endings In 10-20% of cases, can see polyarticular involvement GC typically monoarticular but commonly polyarticular Often have fever & separate infection as well (only see fever in ~60% of cases) Diagnostics Arthrocentesis:  Gold standard  Tap joint even if acceptable ROM: septic joints can have normal motion so it does not exclude the diagnosis! Use ultrasound if possible Relative contraindications: overlying cellulitis (risk of seeding joint) or severe coagulopathies (weigh risk of creation or worsening of iatrogenic hemarthrosis) Keep in mind that a “dry tap” may occur due to incorrect needle placement, absent/ minimal joint effusion, ort mechanical obstruction Note: talk to ortho colleagues if prosthesis present prior to performing arthrocentesis
