QBANK CARDS Flashcards
AVNRT
Atrioventricular Nodal Re entrant Tachycardia
- Most common form of paroxysmal Supra ventricular Tachycardia (SVT)
- Caused by a reentry mechanism do to presence a dual electrical pathway (slow & fast pathway) in the AV node.
- Vagal maneuvers increase parasympathetic tone which will cause temporary slowing of conduction in the AV node and an increase in the AV node refractory period leading to termination of AVNRT.
Urine Incontinence
STRESS
URGENCY
MIXED
OVERFLOW
Urine Incontinence /Stress/Tx
Leaking with valsalva
Lifestyle modification
Pelvic floor exercises
Pessary
Pelvic floor surgery
Urine Incontenence / Urgency / TX
Sudden, overwhelming or frequency need to void.
Tx: - lifestyle modification
- bladder training
- antimuscarinic drugs
Urine Incontinence/ Mixed /Tx
Feature stress and urgency
Tx: variable depends on predominant symptom.
Urine Incontinence / Overflow / Tx
Constant involuntary dribbling and incomplete emptying
Tx: - Identification and correction of underlying cause
- Cholinergic agonists
- intermittent self catheterization
Detrusor over activity
By Parasympathetic
Need to void + loss of urine
Tx:
OXYBUTYNIN
Decrease Ach activity (help increase bladder capacity and decrease detrusor contraction) decrease sense of urgency
If patient can’t tolerate antimuscarinic treatment due to the side effects ( dry mouth, constipation, blurry vision )
MIRABEGRON
BETA adrenergic agonist
Essential tremor
Tx: 1) BB (propanolol)
2) Anticonvulsants (Primidone)
- Howerver non selective Beta blocker are relatively contraindicated in patients with reactive airway disease
(Asthma, COPD, Heart block )
PRIMIDONE
Clozapine
Agranulocytosis (neutropenia)
Weight gain
Metabolic syndrome
Seizures
Ileus
Myocarditis
Hypothyroidism
Topical glucocorticoid (eye drops)
Systemic glucocorticoid
Can raise IOP ( Intraocular pressure )
Lhermitte Sign
Neuropathic pain
With neck movement
Fetal Hydrops
Inmune -> Rh Alloinmunization
Non inmune -> Parvovirus B19
-> Fetal Aneuploidy
-> Cardiovascular abnormalities
-> Thalassemia (Hb Barts)
OAG (open angle glaucoma)
Insidious loss of peripheral vision related to atrophy of the optic nerve head.
Signs: enlargement of the optic cup and increase cup disc ratio (cupping of optic disc) late finding.
- patient with steroid induced OAG, may develop central blurriness due to central edema.
- Chronic use of glucocorticoid
=> Cataracts
Hereditary Spherocytosis
Clx: hemolytic Anemia
Jaundice
Splenomegaly
Lab:
⬆️ MCHC
(-) COOMBS Test
Spherocytosis on peripheral smear
⬆️ Osmotic fragility on acidify glycerol lysis test
Abnormal eusin -5 maleimide biding test
Beck triad
Hypotension
JVD
Decreased heart sounds
