Q

Glucose metabolism in the brain is increased in comparison to the waking state.
A. REM sleep
B. non-rapid eye movement (NREM) sleep
C. both
D. neither

A

A. REM sleep
For questions 108-113 see V&A pp. 405-407. Although most dreams occur inrapid eye movement (REM) sleep, they can occur in non-REM (NREM) sleep.Adult somnambulism, K complexes, and sleep spindles all occur in NREM sleep (the latter two in stage 2). Glucose metabolism in the brain isincreased in REM and decreased in NREM sleep in comparison to the wakingstate.

Q

Three clinical forms are noted.

B. glycogen storage disease type V (McArdle’s disease)
C. both
D. neither

A

D. neither
For questions 114-117 see V&A pp. 1513-1516. Glycogen storage disease type I1results from acid maltase (alpha-1,4-glucosidase) deficiency and has threeforms: childhood (Pompe’s disease), childhood, and adult forms. Glycogenaccumulates in lysosomes throughout the body. Glycogen storage diseasetype V (McArdle’s disease) results from myophosphorylase deficiency.Glycogen cannot be converted to glucose-6-phosphate, and the blood lactatedoes not rise after ischemic exercise. Both types

Q 
Wilson's disease is characterized by
I. high urinary copper excretion
11. high serum copper
111. low ceruloplasmin levels

A. I, 11, 111
B. I, I11
C. 11, IV
D. IVE. all of the above
A

B. high urinary copper excretion, . low ceruloplasmin levels
V&A pp. 1026-1030. Wilson’s disease is characterized by an increased urinarycopper excretion, low serum copper levels, and low ceruloplasminlevels. The computed tomographic (CT) scan sometimes shows hypodenseareas in the lenticular nuclei.

118
Q

Each of the following is true of central pontine myelinolysis except
A. A marked inflammatory response with destruction of nerve cells in thepons is seen.
B. It is associated with rapid correction of hyponatremia.
C. It is associated with chronic alcoholism.
D. Quadriplegia, pseudobulbar palsy, and a locked in syndrome can occur.
E. Some patients have no signs or symptoms referable to the pontine lesion.

A

A. A marked inflammatory response with destruction of nerve cells in thepons is seen.
V&A p. 1193. Microscopically, destruction of the medullated sheaths withrelative sparing of the axis cylinders and preservation of nerve cells in thepons is seen. An inflammatory response is absent.

A

D. protein of 35 mg%
V&A p. 758. The protein is elevated in tuberculous meningitis; usually 100 to
200 mg/dL.
