What are the symptoms of nephrotic syndrome? Nephrotic syndrome is a kidney disorder characterized by a specific group of symptoms resulting from damage to the glomeruli, the filtering units of the kidneys.

What are the symptoms of nephrogenic systemic fibrosis? Nephrogenic systemic fibrosis (NSF) is a rare condition that primarily affects individuals with kidney dysfunction, particularly those with end-stage renal disease or those undergoing dialysis.

What are the symptoms of nephrogenic diabetes insipidus? Nephrogenic diabetes insipidus (DI) is a condition characterized by the kidneys’ inability to concentrate urine due to a lack of response to the antidiuretic hormone (ADH) (also known as vasopressin). This results in excessive urination (polyuria) and increased thirst (polydipsia). The symptoms of nephrogenic diabetes insipidus can…

What are the symptoms of neovascularization of the eye? Neovascularization of the eye, also known as ocular neovascularization, refers to the growth of new blood vessels in the eye, often in response to ischemia (lack of blood flow) or other pathological processes. This condition can occur in various parts of the eye, including the retina,…

What are the symptoms of neonatal opioid withdrawal syndrome? Neonatal Opioid Withdrawal Syndrome (NOWS) occurs when a newborn experiences withdrawal symptoms due to exposure to opioids while in utero. This exposure can result from the mother taking prescription opioids, using illicit opioids, or receiving medication-assisted treatment with methadone or buprenorphine during pregnancy. The symptoms of…

What are the symptoms of neonatal lupus? Neonatal lupus erythematosus (NLE) is a rare condition that affects infants of mothers with certain autoimmune diseases, most commonly systemic lupus erythematosus (SLE).
