None of the above", "role": "user" }, { "content": "Answer: B \nExplanation: Ans. is 'b' i.e., Non perpendicular principal meridians ASTIGMATISMo Astigmatism is a type of refractive error wherein the refraction varies in the different meridia. Consequently, the rays of light entering in the eye cannot converge to a point focus but form focal lines. The refractive error of the astigmatic eye stems from a difference in degree of curvature refraction of the two different meridians (i.e.,, the eye has different focal point in different planes). For example, the image may be clearly focused on retina in the horizontal plane, but not in the vertical plane.o The most common cause of astigmatism is abnormality of corneal curvature. Other less common causes are lenticular (curvature abnormality of lens,oblique position of lens) and retinal (oblique placement of macula). Types of astigmatismBased on axis of the principal meridiansRegular stigmatism : Principal meridians are perpendicularo With-the-rule astigmatism-the vertical meridian is steepest.o Against-the-rule astigmatism-the horizontal meridian is steepest.o Oblique astigmatism-the steepest curve lies in between 120 and 150 degrees and 30 and 60 degrees.Irregular astigmatism - principal meridians are not perpendicular.Based on focus of the principal meridiansSimple astigmatismo Simple hyperopic astigmatism - first focal line is on retina while the second is located behind the retinao Simple myopic astigmatism - first focal line is in front of the retina while the second is on the retina.Compound astigmatismo Compound hyperopic astigmatism-both focal lines are located behind the retina,o Compound myopic astigmatism-both focal lines are located in front of the retina.Mixed astigmatism-focal lines are on both sides of the retina (straddling the retina).Treatment of Astigmatismo Treatment of astigmatism consists : -Optical treatment: - It consists of cylindrical power spectacles or contact lens.

The relative youthfulness of the patient often rules out prostatic enlargement, which characteristically occurs after the age of 50. As the stream becomes narrower, micturition is prolonged and is followed by postmicturition dribbling as a result of urine trickling from the dilated urethra proximal to the stricture. Urinary frequency by day and night is common and is due to incomplete bladder emptying, coexisting detrusor overactivity or urinary infection. If the stricture is tight enough, the patient will go into acute retention, although this is rare. If this happens, there is a danger that clumsy attempts to pass a urethral catheter will result in a false passage. If a patient has gone into retention because of a urethral stricture, its lumen will be too narrow to pass even a tiny catheter and suprapubic catheterisation is required. Investigation involves uroflowmetry, urethroscopy, urethrography and ultrasound scanning to assess bladder emptying and to detect any upper tract dilatation. The urinary flow rate is typically prolonged and plateau shaped while urethroscopy allows the stricture to be viewedas a circumferential scar. Openings of false passages commemorate previous misguided attempts to pass a urethral catheter. Urethrography using a water-soluble contrast medium will show the extent and severity of the stricture Ref: Bailey and love 27th edition Pgno : 1482", "role": "assistant" } ]

Scar tissue formation may be secondary to previous granulomatous disease (tuberculosis), infarction, or interstitial diseases of the lung associated with fibrosis (e.g., progressive systemic sclerosis). The pathogenesis of scar carcinoma is not completely understood. One theory is that scar tissue blocks lymphatic drainage, causing an increased concentration of anthracotic pigment-containing carcinogens.

It occurs in cytosol 3 Carbon atoms end product (pyruvate or lactate) is produced. Irreversible steps are catalyzed by : - Glucokinase/Hexokinase, phosphofructohnase-I, and pyruvate kinase. Reversible steps are catalyzed by : - Phosphohexose isomerase, aldolase, phosphotriose isomerase, glyceraldehyde 3-phosphate dehydrogenase, Phosphoglycerate kinase, Phosphoglycerate mutase, Enolase. Energy (ATP) using steps are catalyzee by : - Hexokinase/glucokinase, phosphofurctokinase. Energy (ATP) production at substrate level are catalyzed by : Phosphoglycerate kinase, Pyruvate kinase. Reducing equivalent (NADH) production is catalyzed by : Glyceraldehyde 3-phosphate dehydrogenase. Cancer cells derive nutrition from glycolysis as they have lack of 02 supply because of lack of capillary network.

In this disease, the skin shows atrophic alterations. Changes in the head include thin eyebrows, loss of eyelashes, sharp features, thin lips, and an immobile expression.
