Arachnoid granulations (also arachnoid villi, and Pacchionian granulations or bodies) are small outpouchings of the arachnoid mater and subarachnoid space into the dural venous sinuses of the brain. The granulations are thought to mediate the draining of cerebrospinal fluid (CSF) from the subarachnoid space into the venous system .
Arachnoiditis is an inflammatory condition of the arachnoid mater or 'arachnoid', one of the membranes known as meninges that surround and protect the central nervous system. The outermost layer of the meninges is the dura mater (Latin for hard) and adheres to inner surface of the skull and vertebrae. [ 1 ]
Hypomagnesemic hypercalciuric nephrocalcinosis (magnesium-losing kidney)[248250] PCLN1: 3q27: AR: Nephrocalcinosis, renal failure, ocular/hearing defects, polyruria, polydipsia, recurrent urinary tract infections, recurrent renal colic, normotensive: Plasma: ↓Mg, ↑PTH; Urine: ↑Ca, ↑Mg Distal Tubule/Collecting Duct: Liddle's syndrome ...
[1] [2] They receive blood from the cerebral veins, and cerebrospinal fluid (CSF) from the subarachnoid space via arachnoid granulations. They mainly empty into the internal jugular vein. [2] Cranial venous sinuses communicate with veins outside the skull through emissary veins. These communications help to keep the pressure of blood in the ...
Pyelonephritis is inflammation of the kidney, typically due to a bacterial infection. [3] Symptoms most often include fever and flank tenderness. [2] Other symptoms may include nausea, burning with urination, and frequent urination. [2] Complications may include pus around the kidney, sepsis, or kidney failure. [3]
It has been proposed that a positive biofeedback loop may exist, where raised ICP (intracranial pressure) causes venous narrowing in the transverse sinuses, resulting in venous hypertension (raised venous pressure), decreased CSF resorption via arachnoid granulation and further rise in ICP.
Interstitial nephritis is uncommon (<1% incidence) in patients without any symptoms but occurs in about 10-15% of hospitalized patients with acute kidney injury of unknown cause. [2] While it can occur in patients of all ages, it is more common in elderly patients, perhaps due to increased exposure to drugs and other triggering causes.
