4

meningococci vaccine?

yes but type B not widely available

5

other route of infection of gonorrhea? presentation?

perinatally (causes neonatal conjunctivitis)

6

What is Fitz-Hugh-Curtis caused by?

gonorrhea

7

other presentation of meningococcemia?

gangrene of toes

8

treatment for gonorrhea conjunctivits?

Fitz-Hugh-Curtis syndrome

o Coded character: Chanelle O’conner/seen in women with PID. Ascending, polymicrobial infection of the female genital tract that can involve the endometrium, uterine tube, and/or peritoneal cavity. House is full of adhesions from the roof to a hippo/infection of the liver capsule and “violin string” adhesions of peritoneum to liver. Perihepatitis is a complication that presents with RUQ pain. She’s profusely sweating + has discharge from her vagina/classic triad is fever + abdominal pain + vaginal discharge. Robby Page is licking up the discharge/caused by gonococci.
o Location: Hallweaver’s house on P street.
