UW Flashcards
Friedrich Ataxia
Autosomal recessive
Progressive gait ataxia and dysarthria in teens.
Due to degeneration of spinal tracts.
Also presents with hypertrophic cardiomyopathy, scoliosis, diabetes.
Vitamin Deficiencies in Cystic Fibrosis
Fat soluble vitamins, ADEK.
Vit. K deficiency leads to bleeding problems (↑PT)
Turner Syndrome
Coarctation of aorta
Short stature
Ovarian dysgenesis –> amenorrhea –> ↑bone fractures
Cat-scratch disease
Non-painful
Regional lymphadenopathy +/- fever
Tx w/ azithromycin
Iron poisoning Tx
Deferoxamine
Shaken baby
Retinal hemorrhages, subdural bleed
Should do non-contrast CT of head and skeletal survey to look for signs of abuse
Cystinuria
Recurent hx stones (hexagonal crystals)
Caused by poor renal reabsorption of cystine –> accumulation.
Test w/ cyanide-nitroprusside test
Vascular ring vs laryngomalacia
Laryngomalacia is from collapsing supraglottic structures during inspiration leading to inspiratory stridor that improves when prone.
Vascular ring is aortic arch forming around esophagus and trachea leading to constriction and inspiratory + expiratory stridor. Extending the neck pulls airway enough to decompress them and improve symptoms.
Duchenne Muscular dystrophy
Gene deletion of dystrophin (X-linked recessive) -> severe proximal LE weakness –> Gower Sign (using hands to walk themselves up to standing).
Large calves from fat replacement of muscle
Progressively worsens to heart/respiratory failure.
Common cause of recurrent UTIs
Constipation –> rectal distension –> poor voiding –> UTI
Treatment for ring worm
Topical clotrimazole
First line treatment of lyme disease
Oral doxycycline
Findings of Reye Syndrome
Aspirin during flu or varicella infection.
Encephalopathy (seizures)
Acute liver failure
Cerebral edema -> increased intracranial pressure
Main risk of rotavirus vaccine
Intussusception
Contraindicated in kids with previous intussusception
Next step after positive ortolani & barlow maneuvers
Ultrasound of the hips
