Reference :Harrison Principles of Medicine

Transient or Sudden Visual Loss

Amaurosis Fugax

This term refers to a transient ischemic attack of the retina (Chap. 364). Because neural tissue has a high rate of metabolism, interruption of blood flow to the retina for more than a few seconds results in transient monocular blindness, a term used interchangeably with amaurosis fugax. Patients describe a rapid fading of vision like a curtain descending, sometimes affecting only a portion of the visual field. Amaurosis fugax usually occurs from an embolus that becomes stuck within a retinal arteriole (Fig. 29-5). If the embolus breaks up or passes, flow is restored and vision returns quickly to normal without permanent damage. With prolonged interruption of blood flow, the inner retina suffers infarction. Ophthalmoscopy reveals zones of whitened, edematous retina following the distribution of branch retinal arterioles. Complete occlusion of the central retinal artery produces arrest of blood flow and a milky retina with a cherry-red fovea (Fig. 29-6). Emboli are composed of either cholesterol (Hollenhorst plaque), calcium, or platelet-fibrin debris. The most common source is an atherosclerotic plaque in the***** carotid artery or aorta, although emboli can also arise from the heart, especially in patients with diseased valves, atrial fibrillation, or wall motion abnormalities.

96. which alpha 2 agonist is used to relieve spasticity in amyotrophic lateral sclerosis?
A.clonidine
B.Brimonidine
C.Apraclonidine
D.Tizanidine

Ans:D.Tizanidine

Reference:Katzung Pharmacology


Tizanidine

As noted in Chapter 11, agonists such as clonidine and other imidazoline compounds have a variety of effects on the central nervous system that are not fully understood. Among these effects is the ability to reduce muscle spasm. Tizanidine is a congener of clonidine that has been studied for its ***spasmolytic actions. ***Tizanidine has *****significant 2-adrenoceptor agonist effects, but it reduces spasticity in experimental models at doses that cause fewer cardiovascular effects than clonidine. Neurophysiologic studies in animals and humans suggest that tizanidine reinforces both presynaptic and postsynaptic inhibition in the cord. It also inhibits nociceptive transmission in the spinal dorsal horn.

99. retroperitoneal fibrosis MC presents as
A.b/l pedal edema
B.ascites
C.ureteral obstruction
D.--

Ans:C.ureteral obstruction(REPEAT)

Reference:Sabiston

The fibrosis is usually confined to the central and paravertebral spaces between the renal arteries and sacrum and tends to encase the aorta, inferior vena cava, and ureters. The process usually begins at the level of the aortic bifurcation and spreads cephalad. In 15% of instances, the fibrotic process extends outside of the retroperitoneum to also involve the peripancreatic and periduodenal spaces, the pelvis, and the mediastinum.

Patients present with a vague constellation of symptoms, including abdominal or flank pain, weight loss, malaise, and hypertension. Scrotal or leg edema caused by lymphatic obstruction may also be present. Laboratory tests often provide evidence of renal insufficiency and anemia. Other laboratory abnormalities include an elevated erythrocyte sedimentation rate and an elevated C-reactive protein level.

B.20%
C.60%
D.80%

Ans: C.60%

Refernce : Harrison Medicine

H. pylori infection is virtually always associated with a chronic active gastritis, but only 10–15% of infected individuals develop frank peptic ulceration. The basis for this difference is unknown. Initial studies suggested that >90% of all DUs were associated with H. pylori, but H. pylori is present in only *****30–60% of individuals with ****GUs and 50–70% of patients with DUs.
