Fistula Test





How are the results of Fistula test interpreted?
1. In fistula over the dome of the lateral semicircular canal: Increase pressure causes conjugate horizontal deviation of the eyes towards the normal side. As pressure is maintained, jerk nystagmus develops with fast component towards the affected ear. As pressure is released, eyes return to normal

2. Fistula of the lateral semicircular canal (anterior to the ampulla) causes deviation of eyes, to the affected side

3. Vestibular erosion causes rotatory horizontal nystagmus towards the diseased ear

4. Fistula of the posterior semicircular canal causes vertical movement of eyes.

Peripheral signs of AR:

Peripheral signs of AR:
large-volume, 'collapsing' pulse also known as:
Watson's water hammer pulse
Corrigan's pulse (rapid upstroke and collapse of the carotid artery pulse)
low diastolic and increased pulse pressure
de Musset's sign (head nodding in time with the heart beat)
Quincke's sign (pulsation of the capillary bed in the nail; named for Heinrich Quincke)
Traube's sign (a 'pistol shot' systolic sound heard over the femoral)
Duroziez's sign (systolic and diastolic murmurs heard over the femoral artery when it is gradually compressed with the stethoscope)
Also, these are usually less detectable in acute cases.
Less used signs include:
Lighthouse sign (blanching & flushing of forehead)
Landolfi's sign (alternating constriction & dilatation of pupil)
Becker's sign (pulsations of retinal vessels)
Müller's sign (pulsations of uvula)
Mayen's sign (diastolic drop of BP>15 mm Hg with arm raised)
Rosenbach's sign (pulsatile liver)
Gerhardt's sign (enlarged spleen)
Hill's sign - a ≥ 20 mmHg difference in popliteal and brachial systolic cuff pressures, seen in chronic severe AI. Considered to be an artefact of sphygmomanometric lower limb pressure measurement.
Lincoln sign (pulsatile popliteal)
Sherman sign (dorsalis pedis pulse is Quickly located & unexpectedly prominent  age>75 yr)
Ashrafian sign (Pulsatile pseudo-proptosis)
Cor en sabot(boot shaped heart)- TOF
Cor bovinum- 3° syphilis. N chronic AR..
