After age 40, creatinine clearance decreases an average of 8 mL/min/1.73 m2/decade; however, the age-related decrease varies substantially from person to person. Serum creatinine levels often remain within normal limits despite a decrease in GFR because older adults generally have less muscle mass and are generally less physically active than younger adults and thus produce less creatinine. Maintenance of normal serum creatinine levels can mislead clinicians who assume those levels reflect normal kidney function. Decreases in tubular function with age parallel those in glomerular function. Refer katzung 11/e p1039", "role": "assistant"}] |

This is not a good screening test but a positive result is highly specific. The best investigation would be cystoscopy & biopsy. Investigations for bladder cancer 1. Urinary cytology - Exfoliated cells from both normal and neoplastic urothelium can be readily identified in voided urine. Examination of cytological specimens can detect the malignant cells either at the time of initial presentation or during follow-up. Cytological examination may be especially useful in screening high-risk population and assessing the response to treatment. 2. Cystourethroscopy and tumor resection - The diagnosis and initial staging of bladder cancer is made by cystoscopy and transurethral resection. 3.Imaging (IVP, CT, MRI) - Although various imaging techniques can detect bladder cancer, its presence is confirmed by cystoscopy & biopsy. - Therefore imaging modalities are used to image the upper urinary tract and, when infiltrating bladder tumors are detected to assess the depth of muscle wall infiltration and the presence of local & distant metastasis. - Intravenous urography remains one of the most common imaging tests for the evaluation of hematuria. However, intravenous pyelography is increasingly being replaced by computed tomography (CT) urography, which is more accurate, for evaluation of the entire abdominal cavity, renal parenchyma, and ureters in patients with hematuria. Bladder tumors may be recognized as pedunculated, radiolucent filling defects projecting into the lumen; nonpapillary, infiltrating tumors may result in fixation or flattening of the bladder wall. 4. Urinary tumor markers - - Several new tests have been developed in order to overcome the shocomings of urinary cytology such as the low sensitivity for low-grade superficial tumors and inter-observer variability. - Commercially available tests include, the BTA test, the BTA stat test, the BTA TRAK assay determination of urinary nuclear matrix protein (NMP22), Immunocyt and UroVysion . - These tests can detect cancer specific proteins in urine (BTA/NMP22) or augment cytology by identifying cell surface or cytogenetic markers in the nucleus. Other tests under investigation include identification of the Lewis X antigen on exfoliated urothelial cells, and the determination of telomerase activity in exfoliated cells. - These tests have been demonstrated to enhance detection of bladder cancer when used either individually or in combination with cytology. They have been used to detect both new index tumors as well as recurrent tumors.", "role": "assistant"}] |

The RV, the FRC, and the TLC, however, cannot be determined with a spirometer because the subject cannot exhale all the gas in the lungs. The lung volumes not measurable with spirometry can be determined by the nitrogen-washout technique, by the helium-dilution technique, and by body plethysmography. The FRC is usually determined, and RV (which is equal to FRC minus ERV) and the TLC (which is equal to VC plus RV) are then calculated from volumes obtained by spirometry. Ref: Levitzky M.G. (2007).

According to this hypothesis, atherosclerosis is a chronic inflammatory response of the aerial wall initiated by injury to endothelium. Pathogenesis of atherosclerosis Following stages occurs in the pathogenesis of Atherosclerosis: Endothelial injury Earliest stages of the development of atherosclerosis are mediated by the inflammatory cascade. Inflammation mediated injury to endothelium is the cornestone in the development of atherosclerosis. After injury, endothelium is activated and there is increased expression of adhesion molecule-VCAM-1 and there is increased permeability to endothelium. TNF is the major cytokine to induce this expression. Migration of leukocytes When VCAM-1 is expressed on endothelium, leukocytes adhere to the endothelium. Leukocytes than cross the endothelial barrier and begin to accumulate in subendothelial intimal space. Macrophages engulf LDL cholesterol and form foam cells - formation of earliest lesion, i.e. fatty streak. Macrophages also form oxygen free radicals that cause oxidation of LDL to yield oxidized LDL (modified LDL). Smooth muscle cell migration and proliferation Inflammatory cells in subendothelial intimal space secrete cytokines, mainly PDGF, TGF-ct and FGF which cause migration of smooth muscle cells from media to subendothelial intimal space as well as their proliferation. Maturation of plaque Smooth muscle cells synthesize extracellular matrix (especially collegen) and conve a fatty streak into a mature fibrofatty atheroma, and contribute to the progressive growth of atherosclerotic lesions.", "role": "assistant"}] |

Pg 156Explanation:Kawasaki disease is associated with hydrops of gallbladder.Gallbladder Wall Thickening A gallbladder wall that is thickened is a sign of inflammation. This is a non-specific finding, and many other pathologic processes, as well as a postprandial gallbladder, can give you falsely elevated measurements.It is important to measure the wall of the anterior gallbladder surface because of the acoustic enhancement artifact mentioned.Because sound waves travel through a fluid-filled structure, no attenuation occurs. Thus, when those sound weaves hit the back of the gallbladder, they will be so strong that they will obscure an accurate picture of the wall thickness.For gallbladder wall thickness, greater than 3 mm is abnormal.Differential for Thickened Gallbladder WallPostprandialRenal failureAscitesHepatitisHypoalbuminemiaHIV/AIDSAdenomyomatosisMultiple myelomaCholecystitisCongestive heart failure", "role": "assistant"}] |
