Q

What are the 4 types of hearing loss?

A
  1. Conductive: most common in children = interference with mechanical transmission of sound through the external and middle ear
  2. Sensorineural hearing loss: failure to transduce vibrations to neural impulses within the cochlea or transmit impulses down the vestibulocochlear nerve
  3. Mixed hearing loss: combination of both due to damage throughout middle ear and inner ear

Q

What is the protocol for starting psychostimulant medications for chidlren with ADHD?
-different types of psychostimulants

A

Types of 1st line treatment:

  1. Methylphenidate (ritalin, concerta)
  2. Amphetamine

  2. TCAs
  3. Alpha agonists (clonidine)

Over the first 4 weeks, increase the med dose as tolerated to achieve maximum benefit

  • if side effects prevent further dose adjustment or if ineffective, use an alternative class of stimulants
  • ie. if methylphenidate is unsuccessful –> switch to amphetamine –> if unsuccessful, switch to atomoxetine

Q

What are the two types of breath holding spells?

  • when do spells usually begin?
  • treatment?
A

Involuntary breath holding that leads to brief period of unconsciousness and is usually triggered by anger, fear or pain
Two types of breath-holding spells:
1. Pallid = vasovagal reflex, often made worse by iron deficiency anemia, caused by reflex vagal-cardiac bradycardia, occurs in response to being surprised or scared
2. Cyanotic: result from prolonged expiratory apnea causing intrapulmonary shunting, usually from temper

  • ***Each episode starts with a cry (often a “silent” cry and marked pallor in the case of the pallid type) and progresses to apnea and cyanosis
  • spells usually begin between 6-18 months of age, can persist up to 4-6 yo
  • syncope, tonic posturing and even reflex anoxic seizures may follow, particularly in breath-holding spells of the pallid type
  • injury, anger, frustration, particularly with surprise are common triggers
  • education and reassurance of parents is usually all that is needed as these episodes are self-limited and outgrown within a few years
  • treatment of coexisting iron deficiency is needed if present (new evidence shows that you can actually just give iron!)
  • Treatment:
    1. do not provide secondary gain when episodes occur since this can reinforce the episodes = ignore the spells
    2. prepare for unpleasant surprises (such as receiving a shot) rather than surprising the child
  • ***Rarely: may need anticholinergic drugs (atropine), CPR teaching, or antiepileptic drug therapy for anoxic seizures for recurrent episodes

Q

What is the definition of amblyopia?

  • causes?
  • diagnosis?
  • treatment?
A

Amblyopia: loss of visual acuity due to lack of a clear image projecting onto the retina

  • can be secondary to deviated eye (strabismic amblyopia), an unequal need for vision correction between the eyes (anisometropic amblyopia), a high refractive error in both eyes (ametropic amblyopia) or media opacity within the visual axis (deprivation amblyopia)
  • diagnosis: complete ophtho exam revealed reduced acuity that is unexplained by organic abnormality
  • usually asymptomatic and is detected only by screening programs
  • treatment: remove media opacity or prescribe appropriate glasses so that well-focused retinal image can be produced in each eye.
  • the sound eye is then covered (occlusion therapy) or blurred with glasses or drops (penalization therapy) to stimulate proper visual development of the more severely affected eye
  • occlusion therapy can provide speedier improvement in vision but some children better tolerate atropine penalization
  • need close monitoring by ophthalmologist
  • series of prospective studies show that some children can achieve similar results with less patching or use of atropine drops
