Spontaneous hematoma within the iliopsoas muscle (SIH) is a rare complication most commonly seen in coagulopathic patients. Often, patients undergoing microvascular free tissue transfer are anticoagulated for anastomotic patency. Here we describe two cases of postoperative SIH following contralateral anterolateral thigh (ALT) free tissue transfer for reconstruction of oncologic head and neck de...

A 51-year-old woman presented with a rare case of spontaneous intracranial hypotension (SIH) complicated by a delayed subdural hematoma (SDH) that required surgical evacuation 2 months after epidural blood patching (EBP). Subdural fluid collections are common among patients with SIH. These fluid collections vary in appearance from thin subdural hygromas to rare large SDHs associated with signif...

It was with great interest that we read the paper by Girgis et al. (3) and the related papers regarding spontaneous intracranial hypotension (SIH) in Turkish Neurosurgery. SIH is characterized with orthostatic headache, diffuse dural enhancement on MRI and low cerebrospinal fluid pressure in the absence of trauma history or lumbar puncture (3). Herein, we aimed to share our experience in a man ...

Time-resolved studies of silylene, SiH, , generated by laser flash photolysis of phenylsilane, have been carried out to obtain rate constants for its bimolecular reaction with monosilane, SiH4. The reaction was studied in t he gas phase over the pressure range 1-100 Torr, with both Ar and SF, as bath gases, at six temperatures in the range 298-665 K. The reaction of SiH, with SiH, to form disil...

This review article focuses on the recent applications of tris(trimethylsilyl)silane as a radical-based reagent in organic chemistry. Numerous examples of the successful use of (TMS)(3)SiH in radical reductions, hydrosilylation and consecutive radical reactions are given. The use of (TMS)(3)SiH allows reactions to be carried out under mild conditions with excellent yields of products and remark...

BACKGROUND Spontaneous intracranial hypotension (SIH) is a well-recognized neurologic disorder that typically presents with orthostatic headaches, low cerebral spinal fluid pressures and distinct abnormalities on magnetic resonance imaging. METHODS We present a case of a rare presentation of SIH. RESULTS A 49-year-old man presented with a two week history of orthostatic headaches that rapid...

RATIONALE G protein-coupled receptor kinases (GRKs) are dynamic regulators of cellular signaling. GRK5 is highly expressed within myocardium and is upregulated in heart failure. Although GRK5 is a critical regulator of cardiac G protein-coupled receptor signaling, recent data has uncovered noncanonical activity of GRK5 within nuclei that plays a key role in pathological hypertrophy. Targeted ca...

Ionizing radiation causes DNA damage and consequent apoptosis, mainly due to the production of hydroxyl radicals (HO•) that follows radiolytic splitting of water. However, superoxide (O2•-) and H2O2 also form and induce oxidative stress with resulting LMP (lysosomal membrane permeabilization) arising from iron-catalysed oxidative events. The latter will contribute significantly to radiation-ind...

Self-inflicted harm (SIH) has a substantial lifetime prevalence, it is associated with tremendous costs, and its rate is increasing on a national scale. To examine the characteristics of those admitted for SIH in the US and to investigate the factors that potentially modify the methods used for SIH. This was a retrospective analysis of admitted cases of SIH including suicide attempts between 20...

BACKGROUND AND PURPOSE The radiologic diagnosis of idiopathic intracranial hypertension (IIH) is one of exclusion, with no reproducible positive features described in the imaging literature. Because MR venography is prone to flow artifacts, diagnosis of secondary intracranial hypertension (SIH) can also be problematic. Vascular hydraulics can be useful for diagnosis of these conditions when mea...
