"While we found a statistically significant higher renal contrast excretion in patients with SIH compared with patients without SIH during early-phase CTM, no useful threshold value could be established that could reliably distinguish these groups with both high sensitivity and high specificity."

Intracranial pressure monitoring in patients with spontaneous onset of orthostatic headache - PubMed Portions of this work were presented in abstract and oral presentation form at the Twenty-eighth Anglo-Dutch Migraine Association meeting (08/06/2018), the Tenth Meeting of the International Society f...

📄New paper on ICP monitoring in pts with orthostatic HA and negative imaging found that most common identifiable pressure issue was high pressure (!)

“3 patients had low ICP (8%) and 6 patients had high ICP (16%). The remaining [had neither] (76%).

Most EBPs in the community are performed without imaging guidance.

Case report of how an intact plica dorsalis mediana prevented bilateral spread of blood, necessitating a second EBP under imaging.

Consider when EBP for PDPH “fails.”

“Flow Void Sign”: Flow Artifact on T2-Weighted MRI Can Be an Indicator of Dural Defect Location in Ventral Type 1 Spinal CSF Leaks Patients with spontaneous intracranial hypotension caused by type 1 dural defects typically have an epidural fluid collection on MRI. Still, the location of the defect is not usually readily identifia...

Headache that worsens upon standing may prompt suspicion for CSF leak.

But there is a normal sharp spike in CSF pressure immediately upon standing.

In some patients with IIH or RIH, this can paradoxically cause HA upon standing, tho usually transient.

Fascinating series of articles on CTD in Neurology in #FrontiersinNeurology including #CSFleak and orthostatic HA.

Great discussion and hypotheses- but surprising how little primary data underpins our current understanding. #knownunknowns

Where I did med school they still had beer on the pharmacy for alcoholics to prevent withdrawal during short stays. It was Pabst Blue Ribbon.

My favorite order was “PBR PO PRN”
