nobody............?

a)

Lewy bodies accumulated in the pars compacta of the substantia nigra resulted in cell death.

Hmm, I guess it's essentially the same mechanics for Alzheimer

I thought so, but i dont have answer keys.

thanks.

E
As there was bronchopneumonia he may have viral inclusions pneumonia being of viral origin

E is a possibility yea. But you are guaranteed to find Lewy bodies is not all neurons are dead and phagositized. I wish I could see the answer to this questions.

I go for A, lewy bodies.

  #8

I'd go for A too .. as the history suggests Parkinsons ... and so does the findings .. So .. One would definitely find Lewy bodies .. !! Inclusion bodies .. ?? If the pts supposedly died as a complicatoin on the pneumonia .. one can find inclusion bodies in the Oligodendria ?? whats the pneumonia organism got to do with the pneumonia causing organism .. !

A

  #11

My answer is A.

  #12

i go for A .....based on diagnosis of exclusion..It cant be loss of cell in caudate nucleus becuse lesion in indirect pathways result in hyperactivity disorders, not parkinsons..cant be neuro fibrillary tangles because they are found in Alzeihmers disease where as this is a picture of Pakinsons disease...+ i dont see any attachment of pnumonia with oligodendrocytes ................so A is my answeer

  #13

i go for A !
wish we got to know the answer!

  #14

i feel ans should be d
neurofibrillary tangles

  #15

Classic Parkinson's Disease Dont need any other clues Bronchopneumonia is the Distractor.

the Only Disease with Loss of Pigmented Cells is parkinsonism

Bronchopneumonia is a distractor, thats obvious.

The answer is Lewy bodies. (A) in Sub Nigra. The photomicrograph is given in Robbin's Path Basis of Diseases with the relevant chapter.

Loss of neurons would have been correct if it were in the striatum where there is loss of DAergic neurons with time due to lack of stimulation. But the choice in Qn was "loss of neurons in Caudate nucleus" which is incorrect.

Parkinsonism, especially the idiopathic variety, is associated with dementia of Lewy-body type. (A larger class of Lewy-body dementia includes many non-Alzheimers dementias).
