Flumazenil can reverse the action of:

 # Flumazenil can reverse the action of:

A. Fentanyl

B. Propofol

C. Ketamine

D. Midazolam

The correct answer is D. Midazolam.

Flumazenil is a benzodiazepine (BZD) antagonist. It competes with benzodiazepine agonists and inverse agonists for the benzodiazepine receptor and reverses their depressant or stimulant effects respectively. Flumazenil abolishes the hypnogenic, psychomotor, cognitive and EEG effects of benzodiazepines. Among the options provided, Midazolam is a benzodiazepine. 

Uses: 

• To reverse benzodiazepine anaesthesia 

• Benzodiazepine overdose 

Jannetta procedure is done in:

 # Jannetta procedure is done in:

A. Bell’s palsy

B. Trigeminal neuralgia

C. Herpes Zoster

D. Paresthesias

The correct answer is B. Trigeminal neuralgia.

Microvascular decompression (MVD), also known as the Jannetta procedure, is a neurosurgical procedure used to treat trigeminal neuralgia (along with other cranial nerve neuralgias) a pain syndrome characterized by severe episodes of intense facial pain, and hemifacial spasm. The procedure is also used experimentally to treat tinnitus and vertigo caused by vascular compression on the vestibulocochlear nerve.

Angle between Frankfort horizontal plane and occlusal plane is:

 # Angle between FH plane and Occlusal plane is:

A. 1 degree

B. 10 degrees

C. 27 degrees

D. Parallel to each other

The correct answer is B. 10 degrees.

This is from Down's analysis. The cant measures the slope of occlusal plane to the Frankfort horizontal plane. When the anterior part of plane is lower than the posterior, the angle would be positive. Large positive angles are found in Class II facial patterns. A long mandibular ramus also tends to decrease this angle. The mean value is +9.3° with a range of +1.5° to +9.3°. 

Under metabolic conditions associated with a high rate of fatty acid oxidation, liver produces

 # Under metabolic conditions associated with a high rate of fatty acid oxidation, liver produces:

A. Glutamate

B. Acetoacetate

C. Cholesterol

D. Glycine

The correct answer is B. Acetoacetate.

- The ketone body formation occurs primarily due to non-availability of carbohydrates to the tissues and excessive utilization of fatty acids to meet the energy requirements of the cells. 

- Acetone, Acetoacetate and Beta-hydroxybutyrate are the ketone bodies. 

- Glucagon stimulates ketogenesis whereas insulin inhibits ketogenesis.
