191. Iron deficiency “ low MCV, high TIBC, low ferritin, low iron (<60), high RDW (why? Because some are normocytic and some are microcytic so the range of width will be high), pica kid who eats sand and ice, plummer-vinson (web, low iron, glossitis), cow milk before age 1, exclusive breast-feeding, pregnancy. Tx “ 1st is to find the source of iron loss and fix that (before you give iron!), 2nd transfusion (if needed fast) or oral iron supplements for 6-12 months.
192. Anemia of Chronic Dz “ (how does this work? The body knows diseases (RA, TB, SLE, cancer) love iron, so it will hide iron away in stores (high ferritin) but keep it out of the serum (low serum iron and high TIBC)) if anemia is a/w chronic renal dz, look for Burr cells.
193. Thalassemia “ normal iron (so don™t give iron), target cells, nucleated rbc, x-ray shows crew-cut appearance of skull, dx c Hb electrophoresis, no tx for traits.

NEUROLOGY:

284. Migraine HA “ 70% unilateral, throbbing, aura, photophobia, family history, possible risk of stroke, worse c OCPs/EtOH/chocolate. Tx c NSAIDS, triptans (contraindicated in heart disease), ergots. Prevent c BB 1st, cab™s 2nd, sodium valproate/SSRI/TCAs.
285. Cluster headache “ same time every month/year, males mostly, tearing, redness, pain, rhinorrhea, feels like an ice-pick is shoved in your eye (old question). Tx c 100% oxygen 1st, steroids 2nd.
286. Temporal Arteritis “ >50yo c unilateral temporal HA, scalp tenderness, vision changes, high ESR. 1st step is give steroids, 2nd step temporal artery biopsy.
287. Pseudotumor Cerebri “ aka Benign Intracranial HTN “ increased ICP, HA, visual changes, obese female, papilledema, no focal CNS findings, a/w vitamin A toxicity. Dx c MRI 1st then LP 2nd, tx c azetazolamide.
288. Trigeminal Neuralgia “ pain whenever you touch your face @ 5th cranial nerve distribution. Tx c carbamazapine. Definitive treatment with surgical rhizotomy.
289. Essential Tremor “ at rest and motion. Tx c propranolol. (Tremor at rest only is Parkinson™s or hyperthyroidism, tremor c motion only is cerebellar dysfunction)
290. Nystagmus/Vertigo “ if + focal defecits, the problem is central (vertical nystagmus): cerebellum (CT/MRI), M. Gravis (MRI), Stroke (MRI/CT), phenytoin without an hearing loss or tinnitus. If no focal defecits, the problem is peripheral (in the ears), so pt will have hearing loss and tinnitus. If pt only has vertigo, its benign positional vertigo. If pt has hearing loss and tinnitus with it: Miniere™s disease (chronic disease), Acoustic Neuroma (look for ataxia), Labyrinthitis (acute viral infxn)
291. Epilepsy (as per Kaplan on what is important): do not treat 1st time seizures unless there is a family history, EEG is positive or pt has status epilepticus.
292. Status Epilepticus “ Dx: 1st sodium, 2nd glucose, 3rd calcium, 4th hypoxia, toxicology, CT-head, EEG (last!). Tx: 1st Benzo (lorazepam IV), 2nd Phenytoin, 3rd Barbiturate, 4th Anesthesia (succinylcholine/propofol “ these will just stop the shaking, wont stop the seizure).
293. Absence seizures “ kid stares into space, doing poorly in school, eye blinking, lip smacking, EEG c 3/sec spike and wave pattern. Tx c ethosuximide.
294. TIA “ focal, abrupt onset lasting less than 1 hour, symptoms resolve after 1 day. Risk of stroke in days to weeks. Amorosis fugax (curtain over an eye due to retinal dysfunction) needs Doppler U/S of carotids or MRA. Give heparin acutely (if no contraindications), then long term aspirin. If stenosis >70%, amaurosis fugax/TIA or small, non-disabling stroke do CEA (carotid endarterectomy) and give aspirin. If stenosis <70%, severely disabling stroke, or TIA/stroke in evolution give daily aspirin alone.
295. CVA “ 1st test is CT without contrast (although, if ischemic, it will show negative), 2nd is MRI. Heparin is not given until hemorrhagic stroke is ruled out. If ischemic, give tPA™s if less than 3 hours of onset. If hemorrhagic, control BP and ICP.
296. Ischemic Stroke Locations: MCA “ contralateral hemiplegia, hemianopsia, Broca™ s (nonfluent, babbling)/Wernicke™s (fluent but doesn™t make sense) aphasia. ACA “ contralateral leg paralysis, sphincter incontinence (they cant kick you, so they pee on you); Posterior “ cortical blindness, hemianopsia; Vertebrobasilar “ ataxia, horizontal gaze, nystagmus; Cerebellar “ ataxia and dizziness; As for hemorrhagic, remember that in the thalamus its only sensory loss, in the pontine/internal capsule/putamen its only motor loss.
297. Multiple Sclerosis “ insidious onset of CNS s/s in a woman aged 20-40 with exacerbations and remissions of numbness, parasthesia, weakness, optic neuritis, gait disturbance, incontinence and emotional/mental status changes. Look for classic b/l internuclear opthalmoplegia (lesion @ MLF so you cannot adduct in horizontal gaze) and scanning speech. Babinski may be positive. Entirely CNS (M.gravis and G-Barre are entirely PNS). 1st step is MRI, 2nd test is LP (oligoclonal bands). Tx acute exacerbation c steroids. Prevent next attack c ABC (Avonex (Inf-B), Betaseron (Inf-B) and Copaxone (Glatiramer acetate)). If stuck in 1 position all day, give baclofen or Tizanidine. If incontinent give oxybutinin or bethanacol.
298. Guillain-Barre Syndrome “ h/o URI of GI infection (campylobacter jejuni) or immunization 1 week before develops onset of symmetric, assending progressive weakness or paralysis and loss of DTRs. 1st step is PFTs (MCCOD is respiratory dysfunction due to paralysis, so monitor the pt™s NIF (negative inspiratory force) and if it keeps decreasing, consider intubation). Most accurate test is EMG. When do yo

thanks dr jiggy....that would be great...also i have a question.....about osteomyelitis....
whats is the first test to order?
what is the most sensitive test?
most specific?
gold standard?
i get so confused with this...please shed some light on this

Osteomyelitis “ 1st step is xray (sometimes may show the characteristic periosteal elevation). Most questions will have given you the X-ray and asked for the next test. So the 2nd is MRI, 3rd step is biopsy (not so much for diagnostic purposes, but for treatment purposes rather). When do you choose bone scan? If you cant do MRI (metal, pacemaker, hearing tubes, etc). So to answer your question in the way you asked it...
1st test is X-ray, 2nd test is MRI, 3rd test is Biopsy
Most sensitive is MRI
Most specific is MRI
Gold Standard would probably still be MRI (unless pt cannot get one, then it would be Bone scan)
