Tx for latent TB
9months isoniazid
MI: Lateral wall defect of LV means which coronary a. is occluded:
Left circumflex coronary a.
Recent trip to Africa
Periodic fevers, myalgias
Splenomegaly
thrombocytopenia
Malaria (plasmodium falciparum)
Ppx: antimicrobial
Acute otitis bugs in kids: (3)
*if concurrent purulent conjunctivitis
Tx
Moraxella, strep.pneumo, non-typeable H. influenza.
(adenovirus less common cause-no purulent discharge)
*If concurrent purulent conjunctivitis: H. Influ
Tx: uncomplicated-10day course of amoxicillin
recurrent-amp/clavulanic acid (augmentin)
Myringotomy, tube placement if persistent >3mth or 3 and + occurrences in 6 mth
Kartagener syndrome
autosomal recessive disorder, situs inversus, chronic sinusitis, airway disease bronchiectasis. Primary ciliary dyskinesia
Common causes of recurrent or chronic sinusitis
Air pollution, second hand smoke, inadequately treated acute sinusitis, structural abnormalities, allergic rhinitis (seasonal allergies)
vertigo, unilateral hearing loss, tinnitus
Meniere’s disease
Presbycusis
Loss of hearing with aging,
serous otitis media v.s suppurative otitis media v.s bacterial otitis externa vs. necrotizing otitis externa
- Serous otitis media: fluid in ear but not infected or inflammed, Exam= bulging tympanic membrane
- Suppurative otitis media: Infected fluid in middle ear, will drain purulent fluid tympanic membrane ruptures. Fever, cranky kids, No pain with manipulation of pinna. Staph Aureus.
- Bacterial otitis externa: Swimmer’s ear, pain with manipulation of pinna. Pseudomonas
- Necrotizing otitis externa: aggresive Pseudomonas infection affecting surrounding bone. Fever, pain, purulent drainage but usually elderly and diabetic and immunocompromised
Acute otitis media risk factors in babies
Second hand smoke, no breastfeeding, pacifier use, day care,
PPSV 23 vaccine (pneumococcal polysaccharide vaccine) is given to kids with___
cochlear implants, asplenia, cardiac disease, sickle cell anemia (kids at high risk of pneumococcal diseases). **if less than 2 years old PPSV 13 is better to mount immune response
Tympanostomy for acute otitis media recommended for kids when
3 or + episodes in 6 months or 4+ episodes in 12mth, or high risk of speech and hearing impairment (craniofacial abnrmlaties kids or neurodevlpmtal disorders)
dysphagia vs odynophagia
diffculty swallowing vs pain with swallowing
Thyroglossal duct cysts
Common appearance of neck swelling that moves with protusion of tongue. 1/3rd appear after 20 yo. Thyroglossal duct connects tongue to thyroid. Ectopic tissue often only functional thyroid tissue so get imaging before considering cutting it out.
chronic rhinitis:
- allergic
- non-allergic
AR appears at <20yo w/ watery eyes, sneezing, nasal congestion, watery rhinorrhea. Identifiable triggers. Normal or pale blue mucosa with polyps.
NAR appears >20yo w/ nasal blockage, rhinorrhea and post-nasal drip. Cant ID trigger. Nasal mucosa: nrml or boggy and erythematous. Tx: intranasal glucocorticoids or antihistamines
otalgia
ear pain
cleft lip +/- palate: repair at age___
3 mths of age, RUle of 10: 10lbs, 10 weeks of age, 10g of Hgb
Can be autosomal dominant or recessive or X linked
Negative exercise stress test means…
<1% risk of cardiovascular events in the next year
Factors associated with increased risk of CV event on exercise stress test: -Clinical variables v/s EKG variables
- Clinical variables: poor exercise capacity, angina at low workload, fall in SBP from baseline, chronotopic incompetence
- EKG variables: >1mm ST depression, ST depression at low workload, ST elevations without Q waves, Ventricular arrhythmias
Bronchoprovocation testing for asthma. Positive and diagnostic findings are:
Fall in expiratory volume in 1 sec>10% =positive
if fall >15%=diagnostic
> 20% reduction in FEV1 with methacholine
TCA overdose
list TCA:
amitriptyline, nortriptyline, trimipramine, desipramine. (SNRIs, antihistamine, anticholinergic activity)
Mental status change, seizures, respi depression
Anticholinergic effects: dry mouth, blurred vision, dilated pupils, flushing, hyperthermia, urinary retention
CV effect:sinus tachycardia, arrhythmias, hypotension–> cause most of the death in TCA overdose as it prolongs PR/QRS/QT interval–> V.tach, V.fib
Tx: Sodium bicarbonate, best tx for managing cardiotoxic effects: increases pH and neutralizes TCA (non ionized) making them less available to bind to rapid sodium channels and inhibit them. It also increases extracellular Na.
mydriasis
dilated pupil
refeeding syndrome is due to which electrolyte being low:
phosphate
As dextrose present in TPN is given it shifts Phosphate into cells causing hypophosphatemia–> seizures, rhambdomyolysis, arrhythmias, CHF
obstructive vs. restrictive PFT
Obstructive: decreased FEV1 and decreased FEV1/FVC
Restrictive: decreased FEV1 and FVC but increased FEV1/FV, it will be > 80%
