This syndrome has a 5p deletion 

Cri-du-chat

This gram-negative coccobacillus has a polysaccharide capsule, causes meningitis, epiglottitis, and otitis media, and is targeted by the Hib vaccine.

Haemophilus influenzae type b (Hib)

These three things make up our innate immunity 

physical barriers, immune cells, chemical modulators

MMR

A 6-year-old boy presents with developmental delays, an unusually friendly and talkative personality with strangers ("cocktail party" demeanor), and a strong affinity for music. Genetic testing reveals a microdeletion on chromosome 7. What classic endocrine abnormality (causing polyendocrinopathy) and cardiovascular complication are associated with this syndrome?

What are Hypercalcemia (endocrine) and Vascular/Aortic Stenosis (cardiovascular)

200
These two virulence factors, employed by this catalase negative microbe, destroy complement 

M proteins and peptidase 

200

This innate immune cell creates the phagolysosome 

Neutrophils

A 28-year-old pregnant woman presents for routine prenatal care at 30 weeks gestation. She received Tdap during her last pregnancy 3 years ago. Which of the following is the most appropriate recommendation?

A. No vaccination is needed because she previously received Tdap
B. Give Td instead of Tdap
C. Administer Tdap during this pregnancy
D. Wait until postpartum

12-year-old boy presents with progressive liver disease, tremor, gait ataxia, and joint pain. Diagnostic labs confirm decreased serum ceruloplasmin and elevated 24-hour urinary copper excretion. What is a missing, yet KEY, PE exam finding in this patient? 

Kayser-Flesicher Ring 

300

A 28-year-old pregnant woman is reviewing recommended vaccines. She asks which vaccine helps protect her newborn against a respiratory infection caused by a gram-negative coccobacillus whose virulence factors include filamentous hemagglutinin and pertactin.

Tdap

These two bacteria are common causers of recurrent/severe infections of the ears, sinuses, and lungs 

Streptococcus pnenumoniae

Haemophilus influenzae

What is the difference between Hairy and Oral Leukoplakia 

oral: hyperkeratosis of mucosa in response to irritant (white lesion that won't scrape off.. biopsy if its acting sus) 

hairy: raised white acreas with corrugated surface on lateral border of tongue. Induced by EBV. Common finding in HIV.

Unlike Pneumovax 23, these pneumococcal conjugate vaccines generate a T-cell dependent immune response, leading to immune memory and maturation of the B-cell response.

Prevnar (PCV13/20), Vaxneuvance (PCV15), or Capvaxive (PCV21)

This is the treatment for Maple Syrup Urine Disease

Restrict BCAA intake, give thiamine, gene therapy

A 42-year-old man with functional asplenia presents for preventive care. Which encapsulated organism places him at particularly high risk for overwhelming infection and is specifically covered by routine adult vaccination recommendations?

Streptococcus pneumoniae

400

Deficiency in this, would lead to increased susceptibility for C. albicans and S. aureus infectinos 

phagocytic immune deficiency state (neutrophils and macrophages)

B. A different MenB vaccine increases immunogenicity
C. The same vaccine product must be used for all doses
D. No booster doses are recommended

500

This metabolic disorder presenting with IDD, seizures, hypothermia, loose skin, and hyperpigmented hair would display what type of characteristics on a pedigree? 

Menke's Disease 

- males more affected than females

- female carries common

- no father to son passage - skipped generations

500

This catalase negative bacteria uses the virulence factors: M-proteins/peptidase and Streptolysin O to evade the immune system 

S. pyogenes

500
Deficiency in C3 would lead to these outcomes

- decreased opsonization for phagocytic cells (C3b), trouble recruiting neutrophils to trigger inflammation (C3), trouble with B-lymphocyte recognition (C3D) AND increased H. flu and S. pneumo infections.
