Tripoding and a thumb print sign on X-ray are your buzz words for epiglottitis that you don't want to miss as it can cause very rapid respiratory compromise requiring ICU care. We'll go over what to look out for and how to treat epiglottitis in this week's episode

Key Points:

• Epiglottitis can present with rapid onset fever, sore throat, difficulty breathing, and drooling. On exam, you might see stridor, retractions, and tripoding which is when the patient is leaning forward with their head tilted upward.
• Epiglottitis can lead to respiratory failure and may require intubation
• The most common causes of epiglottitis are Staph aureus, Streptococcus pneumonoiae, and Haemophilus influenzae though the latter has decreased due to vaccination with the Hib vaccine
• Treatment for epiglottitis includes antibiotics like ceftriaxone and vancomycin for 7-10 days. Steroids and racemic epinephrine have not been shown to improve outcomes for epiglottitis.

Key Points:

• RSV immunizations can stimulate an immune response to create antibodies against RSV or can directly give antibodies to an individual
• The RSV vaccine (Abrysvo) for adults can be given to pregnant individuals to provide passive immunity to infants after birth. It should be given at 32-36 weeks of gestational and 2 weeks prior to delivery
• After birth, infants can be given an RSV immunization, either nirsevimab (Beyfortus) or clesrovimab (Enflonsia), which are RSV antibodies. These can be given to all infants less than 8 months old if the pregnant parent did not receive Abrysvo. High risk infants 8-19 months should also receive RSV immunization.

Key Points:

• Measles is a highly contagious vaccine preventable viral infection. From 1 single person infected with measles, an average of 18 people can be infected compared to an average of 10 for Ebola and an average of 6 for COVID.
• 2 doses of the live attenuated measles vaccine is 97% effective at preventing measles infection
• Herd immunity prevents wide-spread measles outbreaks. The threshold needed to prevent large scale measles outbreaks is 95%. Only 92.7% of kindergarteners in the US received both MMR shots for the 2023-2024.
• Symptoms of measles includes cough, conjunctivitis, coryza (rhinorrhea), Koplik spots (white spots in the mouth), and rash spreading from the face down, Serious complications include death (1-3 deaths per 1000 cases), encephalitis (20% mortality), and subacute sclerosing panencephalitis (SSPE) which is almost universally fatal.
