Q

Outline the points of the Centor Criteria and score is required?

A

Vesicles in Tympanic Membrane

99
Q

If a patient mentions they feel dizzy, what questions can you ask to clarify it better?

A
  • Is it a spinning sensation (vertigo)?
  • Is it a feeling of imbalance (disequilibrium)?

  • Is it a feeling of faint (pre-syncope)?
100
Q

How can Vertigo be categorised?

Q

On what set of patients can the HINTS exam be performed?

A

  • Nystagmus
  • A normal full neurological examination
106
Q

Outline the HEAD IMPULSE TEST component of the HINTS exam

A
  • Whilst they’re focusing on your nose, move the patient’s head side-to-side rapidly and then back to the midline
  • If there is a disruption to the vestibular-ocular reflex, so eyes move with head and then saccade back, this is called “corrective saccade” and POSITIVE HEAD IMPULSE TEST
  • If there is NO disruption to the vestibular-ocular reflection, this is termed a “normal” and in a patient with vertigo this would suggest a central cause
107
Q

Outline the NYSTAGMUS component of the HINTS exam

A
  • Observe the patient’s gaze when they are looking directly ahead, and then ask the patient to left and right without fixating on an object
  • If unidirectional nystagmus → Peripheral cause (reassuring)
  • If bidirectional nystagmus → Central cause, highly specific for stroke
108
Q

Q

What is a Thyroglossal Cyst, and how does it form?

A
  • During fetal development, the thyroid gland starts at base of tongue. It then travels down the neck to its final position in front of the trachea, beneath the larynx. It leaves a track behind called the thyroglossal duct, which then disappears
