Question: Abstract: Random-dot stereograms were found to be capable of producing fusional vergence amplitudes in the absence of monocular contours. These vergence amplitudes are not an artefact of monocular contours provided by the target borders or test instrument and are comparable in range to vergence amplitudes measured clinically with second degree fusion targets in an amblyoscope. We conclude that diplopia of monocularly recognisable contours is not necessary for producing fusional vergence amplitudes.
Which is the apt title for the abstract? option1: Vergence amplitudes with random-dot stereograms. option2: Coronary vasodilation by nitrates is not mediated by the prostaglandin system: a quantitative cineangiographic study.

Answer: Vergence amplitudes with random-dot stereograms.

Question: Abstract: To assess whether continuous arteriovenous ultrafiltration (CAVU) might constitute a useful alternative to hemodialysis in the management of patients with advanced liver failure, we carried out CAVU in 3 patients with decompensated Laennec's cirrhosis. CAVU was utilized in two patients with acute renal failure and pulmonary edema to stabilize renal function and facilitate administration of large amounts of fluid. In the third case, CAVU was successfully utilized to mobilize fluid in a patient refractory to conventional diuretic regimens. We conclude that CAVU may constitute an appropriate alternative to traditional hemodialysis in patients with advanced liver disease and renal functional impairment.
Which is the apt title for the abstract? option1: Continuous arterio-venous ultrafiltration in cirrhotic patients with ascites or renal failure. option2: Hepatitis B prophylaxis in dental professionals [letter]

Answer: Continuous arterio-venous ultrafiltration in cirrhotic patients with ascites or renal failure.

Question: Abstract: Pillars of calcification are rarely found in the skin. An interesting case is described where rows of new bone developed in the skin which had been grafted 31 years previously to cover partial skin thickness burns of the shin. The problems of heterotropic ossification are discussed.
Which is the apt title for the abstract? option1: Calcinosis cutis--a rare late complication of burns. option2: Plicatic acid-specific IgE and nonspecific bronchial hyperresponsiveness in western red-cedar workers.

Answer:
Calcinosis cutis--a rare late complication of burns.
