A small amount of reverse T3 (rT3) is also formed.In the normal thyroid, the average distribution of iodinated compounds is 23% MIT, 33% DIT, 35% T4, 7% T3, and 2% reverse T3.",

Can be diagnosed intrauterineExplanationClinical features of ARPKD (Autosomal recessive polycystic kidney disease) are:Classic ARPKD is generally diagnosed in utero or within the neonatal period and characterized by greatly enlarged echogenic kidneys in diseased fetuses. (Option a)Reduced fetal urine production may contribute to oligohydramnios and pulmonary hypoplasia.About 30% of affected neonates die shortly after birth due to respiratory insufficiency. Close to 60% of mortality occurs within the first month of life.In the classic group, most patients are bom with renal insufficiency and ESRD (End stage renal disease). (Option b)However, infants often have a transient improvement in their GFR; death from renal insufficiency at this stage is rare.Some patients are diagnosed after the neonatal stage and form the older group. Morbidity and mortality in this group often involve systemic hypertension, progressive renal insufficiency, and liver manifestations.The hallmarks of ARPKD liver disease are biliary dysgenesis due to a primary ductal plate malformation with associated periportal fibrosis, namely congenital hepatic fibrosis (CHF) and dilatation of intrahepatic bile ducts (Caroli's disease). CHF and Caroli's disease can then lead to portal hypertension exhibiting hepatosplenomegaly, variceal bleeding, and cholangitis.Some patients with the diagnosis of ARPKD at 1 year of age with nephromegaly exhibit slowly declining renal function over 20 years with only minimally enlarged kidneys at ESRD (Option c and e) and markedly atrophic kidneys following renal transplantation.The slow progression of renal disease is likely due to increasing fibrosis rather than the development of cysts.Systemic hypertension is common in all ARPKD patients, even those with normal renal function.

Acute gastritis is also known as hemorrhagic gastritis or acute erosive gastritis. Acute gastritis is associated with the use of nonsteroidal anti-inflammatory drugs, such as aspirin, ibuprofen, and coicosteroids, and also with alcohol, chemotherapy, ischemia, shock, and even severe stress. Two types of stress ulcers are Curling's ulcers, seen in patients with severe burns, and Cushing's ulcers, seen in patients with intracranial lesions. Grossly acute gastritis appears as multiple, scattered, punctate (less than 1 cm) hemorrhagic areas in the gastric mucosa. This is helpful in differentiating acute gastritis from peptic ulcers, which tend to be solitary and larger. Microscopically the gastric mucosa from a patient with acute gastritis is likely to reveal mucosal erosions, scattered neutrophils, edema, and possibly hemorrhage. Acute gastritis.

"content": "Ans. A: Ankylosing Spondylitis The basic pathologic lesion of ankylosing spondylitis occurs at the entheses, which are sites of attachment to bone of ligaments, tendons, and joint capsules. Enthesopathy results from inflammation, with subsequent calcification and ossification at and around the entheses. Inflammation with cellular infiltration by lymphocytes, plasma cells, and polymorphonuclear leukocytes is associated with erosion and eburnation of the subligamentous bone. The process usually stas at the sacroiliac joints. Other enthesopathic sites include the iliac crest, ischial tuberosity, greater trochanter, patella, and calcaneum. Ankylosing spondylitis/ AS/ Bechterew's disease/ Bechterew syndrome/ Marie Strumpell disease/Spondyloahritis is a chronic, painful, degenerative inflammatory ahritis primarily affecting spine and sacroiliac joints, causing eventual fusion of the spine. AS is a systemic rheumatic disease and one of the seronegative spondyloahropathies. About 90% of the patients express the HLA-B27 genotype. Men are affected more than women by a ratio in excess of 10:1. Typical signs of progressed AS are the visible formation of syndesmophytes on X-rays and abnormal bone outgrowths similar to osteophytes affecting the spine. Complete fusion results in a complete rigidity of the spine, a condition known as bamboo spine. In 40% of cases, ankylosing spondylitis is associated with iridocyclitis causing eye pain and photophobia. 4.1 AS is also associated with ulcerative colitis, Crohn's disease, psoriasis, and Reiter's disease Other complications are aoic regurgitation, Achilles tendinitis, AV node block and amyloidosis & restrictive lung disease. A clinical examination and X-ray studies of the spine, which show characteristic spinal changes and sacroiliitis, are the major diagnostic tools. The Schober's test is a useful clinical measure of flexion of the lumbar spine performed during examination.",

When the staing molecule is pyruvate, the oxidative decarboxylation of pyruvate, the oxidative decarboxylation of pyruvate yields 2.5 ATPs and therefore, 12.5 ATPs are produced when staing compound is pyruvate. Since, two molecules of pyruvate enter the TCA cycle when glucose is metabolized (glycolysis produces 2 molecules of pyruvate), the number of ATPs is doubled. Therefore, 25 ATP molecules, per glucose molecule, are produced when pyruvate enters the TCA cycle.Note : Previously calculations were made assuming that NADH produces 3 ATPs and FADH generates 2 ATPs. This will amount a net generation of 30 ATP molecules in TCA per molecule glucose and total 38 molecules from staing. Recent experiments show that these values are overestimates and NADH produces 2.5 ATPs and FADH produces 1.5 ATPs. Therefore, net generation during TCA is 25 ATPs and complete oxidation of glucose through glycolysis plus citric acid cycle yield a net 32 ATPs.Energy yield (number of ATP generated) per molecule of glucose when it is completely oxidized through glycolysis plus citric acid cycle, under aerobic conditions, is as follows :- Method ofNo of ATPsNo of ATPsPathwayStepEnzymeSource ATP formationgained perglucose(new calculation)As per oldcalculationGlycolysis1Hexokinase MinusMinus 1Do3Phosphofructokinase MinusMinus 1Do5Glyceraldehyde-3-p DHNADH Respiratory chain2.5 x 2 = 53 x 2 = 6Do61,3-BPGkinase ATPSubstrate level1 x 2 -- 21 x 2 = 2Do9Pyruvate kinaseATP Substrate level1 x 2 = 21 x 2 = 2Pyruvate to?PyruvateNADH Respiratory chain2.5x2= 53x2= 6Acetyl CoA Dehydrogenase TCA cycle3Isocitrate DHNADH Respiratory chain2.5x2= 53 x 2= 6Do4Alpha keto glutarate DHNADH Respiratory chain2.5x2= 53x2= 6Do5Succinate thiokinaseGTP Substrate level1 x 2 = 21 x 2 = 2Do6Succicinate DHFADH2Respiratory chain1.5x2= 32 x 2= 4Do8Malate DHNADH Respiratory chain2.5x2= 53 x 2= 6Net generation in glycolytic pathway 9 minus 2= 7 10 minus 2= 8Generation in pyruvate dehydrogenase reaction 5 * 6Generation in citric acid cycle 20 * 24Net generation of ATP from one glucose mole 32 * 38",

Teeth erupt normally with no obvious abnormality but rapidly develop mobility resulting from limited root support. In type II, the deciduous teeth are similar to those in dentinogenesis imperfecta, whereas the permanent teeth appear normal.\nRadiological signs\nIn Type I, all the teeth, except the canines, have extremely short roots. The roots are conical or blunted. There is pulpal obliteration and the inferior aspects of the crown exhibit linear crescent-shaped radiolucent lines. Periapical radiolucencies are commonly seen associated with non-carious teeth in Type I dentinal dysplasia. In Type II dentinal dysplasia, obliteration of the pulp occurs post eruption in the deciduous dentition. In the permanent dentition, there is alteration in the configuration of the pulp resulting in enlarged pulp chambers extending well down into the root.

Sympathetic ophthalmia is thought to be an autoimmune inflammatory response toward ocular antigens, specifically a delayed hypersensitivity to melanin-containing structures from the outer segments of the photoreceptor layer of the retina. It is thought that Louis Braille, who injured his left eye as a child, lost vision in his right eye due to SO Floating spots and loss of accommodation are among the earliest symptoms. The disease may progress to severe iridocyclitis with pain and photophobia. Commonly the eye remains relatively painless while the inflammatory disease spreads through the uvea. The retina, however, usually remains uninvolved. Papilledema, secondary glaucoma, vitiligo and poliosis of the eyelashes may accompany SO. Diagnosis is clinical, seeking a history of eye injury. An impoant differential diagnosis is Vogt-Koyanagi-Harada syndrome (VKH), which is thought to have the same pathogenesis, without a history of surgery or penetrating eye injury. Definitive prevention of SO requires prompt (within the first 7 to 10 days following injury) enucleation of the injured eye. Evisceration--the removal of the contents of the globe while leaving the sclera and extraocular muscles intact--is easier to perform, offers long-term orbital stability, and is more aesthetically pleasing. But evisceration may lead to a higher incidence of SO compared to enucleation. Immunosuppressive therapy is the mainstay of treatment for SO. When initiated promptly following injury, it is effective in controlling the inflammation and improving the prognosis.",
