Most common neuroimaging finding of schizophrenia
Most consistently replicated neuroimaging finding in schizophrenia = enlargement of lateral cerebral ventricles
Enlargement of cerebral ventricles in schizophrenia
Clinical feature to distinguish middle vs. anterior cerebral artery occlusion
Middle cerebral artery occlusion => contralateral somatoatosensory and motor deficit in face/arm/leg
vs.
Anterior cerebral artery occlusion => contralateral somatosensory and motor deficit predominantly in LE
First line pharmacologic agent for cancer-related anorexia/cachectic
Progesterone analogus
-lolz not weed (much better for HIV-associated cachexia)
Lab values to differentiate CML from leukemoid reaction
CML: more immature (myelocytes > metamyelocytes), absolute basophilia, low LAP (leukocyte alkaline phosphatase)
Leukemoid rxn to severe infxn: lower (like around 50k), more mature (metamyelocytes > myelocytes), high (normal) LAP, no basophilia
Lab tests to differentiate iron deficiency anemia from thalassemia trait
Both will be microcytic anemias, but iron deficiency will have high RDW and low #RBCs
While thalassemia will have normal RDW and normal number of RBCs
Besides sedation, risk of giving benadryl to elderly M
Benadryl has both antihistamine and anticholinergic properties
Anticholinergic properties => detrusor hypocontractility which may cause acute urinary retentnion in elderly M w/ enlarged prostate
5 mo old girl w/ failure to thrive and a renal tubular acidosis- which type of RTA does she likely have?
Type 1 (distal): not excreting enough protons -most likely to be congenitals
Others: type 2 (proximal): not reabsorbing bicarb (ex: Fanconi syndrome) vs. type 4 (aldo resistance)
Choriocarcinoma
(a) How to make dx
(b) Tx
Chiocarcinoma = gestational trophoblastic tumor
(a) Diagnose w/ elevated beta-hCG way after delivery
(b) Tx w/ chemotherapy
First line tx for VT on ECG
VT:
Main organ systems involved in disseminated histoplasmosis
Disseminated histo (usually in immunocompromised) when it spreads from lungs thru lymph into systemic
Describe the febrile nonhemolytic rxn to transfusion (MC transfusion rxn)
(a) Etiology
MC transfusion reaction is 2/2 (a) Cytokines that build up during storage of the blood
Clinically: w/in 1 hour of transfusion pt w/ fever and chills, but no DIC Or lab abnormalities
Two abx classes to treat legionella pneumonia
Legionella pneumonia = PNA w/ hyponatremia
Tx: macrolides (azithromycin) or quinolones (levofloxacin)
Give the typical presentation of Reye syndrome
Reye syndrome = acute liver failure (transaminitis, coagulopathy, hyperammonemia) and encephalopathy in child after influenza or varicella infection w/ aspirin use
MC location of medulloblastoma
(a) Clinical symptoms
MC location of medulloblastoma = cerebellar vemis (and almost always in the posterior fossa)
(a) => presents w/ cerebellar symptoms, like truncal ataxia
23 yo F w/ progressive lower back pain and stiffness x3 yrs
(a) Dx
(b) Diagnostic test
(a) Dx = ankylosing spondylitis
(b) Diagnose w/ Xray of sacroiliac joints w/ characteristic bamboo spine
- can’t diagnost w/ HLA-B27: present but not specific enough for diagnosis
Key clinical features of Chikungunya fever
Chikungunya fever = mosquito-borne illness in central/S America and tropical regions
High fever + severe symmetric polyarthritis (arthritis is the key here)
Classic CXR findings of contained aortic rupture
(a) vs. CXR findings of bronchial rupture
(a) Bronchial rupture => pneumothorax that doesn’t resolve w/ chest tube, pneumomediastinum, subcutaneous emphysema
Ddx for exudative pleural effusion
Workup for unexplained erythema nodosum
Erythema nodosum = painful lesions on shins associated w/ strep, Tb, sarcoidosis, coccidiomycosis, IBD, Behcets
MS
(a) LP findings
(b) Classic MRI findings
MS
(a) Oligoclonal bands
(b) MRI findings: pericentricular and juxtacortical lesions
Glomerulopathy MC associated w/ renal vein thrombosis
(a) Clinical presentation
Membranous glomerulonephrophaty
(a) Presents as progressive gradual worsening of renal fxn and proteinuria in asymptomatic pt
ex: 6 wks of periorbital edema and abdominal distention, sudden development of R sided abdominal pain fever and gross hematuria
What is euthyroid sick syndrome
Euthyroid sick syndrome aka “low T3” is when T3 is low but T4/TSH normal during an acute illness
When is MSAFP measured to screen for fetal anomalies?
(a) When is it high
(b) When is it low
Maternal serum alpha-fetoprotein screen measured btwn 15-20 weeks to screen for fetal anomalies
(a) High in open neural tube defects (anencephaly, open spina bifida), ventral wall defects (omphalocele, gastrocschisis), multiple gestations
- if high get ultrasound
(b) Low AFP associated w/ aneuploidies (trisomy 18, 21)
