1. the presence of both increased irritability and AV nodal block (such as paroxysmal atrial tachycardia with a 2:1 AV nodal block). is suggestive of..
digoxin toxicity though With toxicity, practically any arrhythmia can be seen.
2. ST segment changes are pretty characteristic, with their "reverse tick" conformation. These changes are not indicative of toxicity, but merely the presence of digitalis

3. Seventy-four percent of all acute rejection episodes occur between 1 and 6 months after transplantation
4. how to manage it?
a percutaneous renal biopsy ( to grade it and to follow response)
treatment modalities include
high-dose steroids alone,
high-dose steroids plus antilymphocyte globulin
or high-dose steroids plus OKT3
(the latter was murine monoclonal antibody to the human CD3 complex).

- in giving a dose of antivenom the age or weight of the patient DOES NOT MATTER. all that matters is the amt of venom injected.

i think studying from the clinicl vignettes first and then doing the initial summary chapters is a better idea than trying to learn the inital ones first...

i am doing q book these days..i havnt heard ppl praise q bank that often..in fact ppl do their step 2 and step 3 q boks before step 2..
relax sheeezo. psych meds are not that tough if u dont allow them to be..in fact u shud study them with the aim of generalization...back then( in med college) i put in a lot of effort in understanding what the syptoms are eg of neuroleptics.not just learning their names but recognizing what they r...its tough work initially but definitely worth it

- to distinguish a SAH from a putamenal hemorrhage look for the neuro deficits.
contralateral conjugate paralysis--> putamen nerve deficits ( CN II--PCA aneurysms, Increased icp--CNVI false localizing sign) - signs of high ICP ( papilledema, headache, n , vomiting etc ) are common to both

approach to vignette with parkinsonism
- if SYMMETRICAL vertical gaze limitation and axial rigidity think progresive supranuclear palsy others ( dementia involves frontal lobe more hippocampal/memory systems) initial symptom-falls Modest response with levodopa imaging unremarkable
- if asymmetrical vertical eye movemnts ok falls late into disease pronounced improvement with med think parkinson's disease
Etcs
cause of Bilateral pallidal necrosis--> Co poisoning
gaze unafected
vascular parinsonism is a d/dt but requires heavy burden of disease
when freaking out
look for VERTICAL gaze in case

Age - Risk of malignancy increases with age
- Risk of 3% at age 35-39 years
- Risk of greater than 50% in patients older than 60 years
- Usually, nodules are identifiable by the time they are 8-10 mm on chest radiographs
- size alone is a pior predictor in a give individual
- The growth rate refers to the doubling time of a nodule, ie, doubling in volume.
- volume of a sphere equals 4/3 pr3; therefore, a 26% increase in diameter on a chest radiograph represents one doubling in volume. ( 2d on x-ray, not 3 d)
- For example, an increase from 1-1.3 cm equals one doubling. A 1-2 cm increase relates to an 8-fold increase in volume.
- Bronchogenic carcinomas usually have a doubling time of 20-400 days
- Doubling times shorter than 20-30 days are seen in infections, infarction, lymphoma, or fast-growing metastases.
- Doubling times greater than 400 days are typically benign
- Absence of change in size of a nodule over 2 years is highly suggestive of a benign lesion.
- of course exceptions occur. CXR may not accurately dectecta 3mm change
