In August 2020, the U.S. Food and Drug Administration (FDA) became aware of nitrosamine impurities in certain samples of rifampin. [61] The FDA and manufacturers are investigating the origin of these impurities in rifampin, and the agency is developing testing methods for regulators and industry to detect the 1-methyl-4-nitrosopiperazine (MNP ...
Putty kidney is a radiological term describing a calcified kidney typically seen in the end stages of chronic renal tuberculosis.The term "putty kidney" derives from the radiographic appearance of extensive amorphous calcification within the kidney, resembling the consistency of putty.
The scarring of the small blood vessels, called capillary sclerosis, is the initial lesion of analgesic nephropathy. [7] Found in the renal pelvis, ureter, and capillaries supplying the nephrons, capillary sclerosis is thought to lead to renal papillary necrosis and, in turn, chronic interstitial nephritis.
The right kidney sits just below the diaphragm and posterior to the liver. The left kidney sits below the diaphragm and posterior to the spleen. On top of each kidney is an adrenal gland. The upper parts of the kidneys are partially protected by the 11th and 12th ribs.
If the kidney injury is the result of dehydration, there may be thirst as well as evidence of fluid depletion on physical examination. [9] Physical examination may also provide other clues as to the underlying cause of the kidney problem, such as a rash in interstitial nephritis (or vasculitis) and a palpable bladder in obstructive nephropathy.

Kidney ischemia [1] is a disease with a high morbidity and mortality rate. [2] Blood vessels shrink and undergo apoptosis which results in poor blood flow in the kidneys. More complications happen when failure of the kidney functions result in toxicity in various parts of the body which may cause septic shock, hypovolemia, and a need for surgery. [3]
The choice of urinary anti-infective agents for patients with renal dysfunction is generally similar to that for individuals with normal kidney function. However, in cases where the patient's glomerular filtration rate (GFR) decreases to less than 20 mL/min, drug dosages adjustment is necessary because achieving the desired therapeutic serum ...
The goal of therapy is to preserve kidney function, reduce the risk of MGRS recurrence after kidney transplant and maintain a sustained hematologic response. The difference of involved-uninvolved free light chains less than 4 or greater than a 90% reduction of involved free light chains are the minimum hematologic responses needed for the ...
