The Effect of Intracranial Pressure on Perifocal Hyperemia
1969
It is known that a reversiblecortical trauma caused by local brain compression in the cat is accompanied by a pronounced decrease of rCBF at the compressed area and by a transient perifocal hyperemia [1].
DEGENERATIVE CERVICAL MYELOPATHY: REVIEW OF SURGICAL OUTCOME PREDICTORS AND NEED FOR MULTIMODAL APPROACH
2020
Degenerative cervical myelopathy is the most common cause of spinal cord injury in the elderly population in the developed world, and it significantly affects the quality of life of patients and their caregivers. Surgery remains the only treatment option able to halt disease progression and provide neurological recovery for most patients. Although it has remained challenging to predict exactly who will experience improvement after surgery, increasingly it has been shown that clinical, imaging, and electrophysiological factors can predict, with relatively good capacity, those more likely to benefit. Clinically, the baseline neurological impairment appears to be strongly related to the outcom…
White cord syndrome after non-contiguous double-level anterior cervical decompression and fusion (ACDF): A “no reflow phenomenon”?
2017
Abstract Study design Case report and review of literature. Objective To report a rare complication of anterior cervical decompression and fusion (ACDF) in a patient with severe cervical cord compression and review of relevant literature. Introduction The white cord syndrome is a very rare condition characterized by an ischemic-edematous lesion of the spinal cord following a surgical procedure, lacking intra o perioperative surgical or anesthesiological complications. Case report A 64-years old male affected by a severe cervical stenosis at multiple levels, with voluminous C3–C4 and C5–C6 disc herniations associated to T2-hyperintense myelomalacic area at C3–C4 level was admitted to our Uni…
Minimally Invasive Surgery for Decompression in Chiari I Malformation
2019
Chiari malformations (CMs) includes different pathologies sharing common anatomic deformities of the brainstem and cerebellum. CM type I was originally introduced by Hans Chiari and described as an “elongation of the tonsils and the medial parts of the inferior lobes of the cerebellum into cone-shaped projections which accompany the medulla oblongata into the spinal canal.” The prevalence of CM has been estimated to be between 0.1% and 0.5%, but it is possible that higher rates will be identified since the increasing the use of magnetic resonance imaging (MRI) in common clinical practice. Clinical studies have shown an equal prevalence in both sexes without particular ethnic or geographic d…
Does the Intrapelvic Compartment Syndrome Exist?
1998
Pelvic compartment syndrome is a rare condition. As in other musculoskeletal localizations, the intra-compartmental pressure raises above a critical level. In the pelvic compartment syndromes, the gluteal compartments are mainly concerned. We report on three patients with bilateral ureteral obstruction, due to compression by a massive retroperitoneal haematoma as a complication of an unstable pelvic ring or acetabular fracture. Anuria with renal organ failure, due to compression of the ureters in the small true pelvis represents an intrapelvic compartment syndrome. Anuria, due to ureteral compression, mostly developing 24 to 48 hours after injury, has to be differentiated from anuria due to…
Long-term effects of graduated compression stockings on cardiorespiratory performance
2015
ABSTRACT: The use of graduated compression stockings (GCS) in sport has been increasing in the last years due to their potential positive effects for athletes. However, there is little evidence to support whether these types of garments actually improve cardiorespiratory performance. The aim of this study was to examine the cardiorespiratory responses of GCS during running after three weeks of regular use. Twenty recreational runners performed three tests on different days: test 1) ¿ a 5-min maximal effort run in order to determine the participants¿ maximal aerobic speed; and tests 2) and 3) ¿ a fatigue running test of 30 minutes at 80% of their maximal aerobic speed with either GCS or PLAC…
Influence of Manual Therapies in Lumbar Disc Herniation A Case Study
2017
Magnetic Resonance Imaging (MRI) has so far been the best way to diagnose disc herniation, the high resolution of images taken on various vertebral tissues allowing the observation, in different planes, of situations such as: the displacement of dural sac and nerve roots, the disc hydration status, which are important data forthe diagnosis and prognosis of disc disease.Manual therapies mainly aim at restoring the lost joint mobility, but also the balance of muscular, skeletal and cranial systems. To this purpose, manipulationtechniques are used for decompression ofthe nerve root affected by disc herniation, spinal hypomobilityandnormalisation ofthe muscles that are peripheral to the lesion.…
A Multicenter International Randomized Controlled Manikin Study on Different Protocols of Cardiopulmonary Resuscitation for Laypeople: The MANI-CPR T…
2021
Background Compression-only cardiopulmonary resuscitation (CPR) is a suggested technique for laypeople facing out-of-hospital cardiac arrest (OHCA). However, it is difficult performing high-quality CPR until emergency medical services arrival with this technique. We aimed to verify whether incorporating intentional interruptions of different frequency and duration increases laypeople's CPR quality during an 8-minute scenario compared with compression-only CPR. Methods We performed a multicenter randomized manikin study selecting participants from 2154 consecutive laypeople who followed a basic life support/automatic external defibrillation course. People who achieved high-quality CPR in 1-m…
A multinational, multidisciplinary consensus for the diagnosis and management of spinal cord compression among patients with mucopolysaccharidosis VI.
2012
Cervical cord compression is a sequela of mucopolysaccharidosis VI, a rare lysosomal storage disorder, and has devastating consequences. An international panel of orthopedic surgeons, neurosurgeons, anesthesiologists, neuroradiologists, metabolic pediatricians, and geneticists pooled their clinical expertise to codify recommendations for diagnosing, monitoring, and managing cervical cord compression; for surgical intervention criteria; and for best airway management practices during imaging or anesthesia. The recommendations offer ideal best practices but also attempt to recognize the worldwide spectrum of resource availability. Functional assessments and clinical neurological examinations …
Vascular Decompression of Trigeminal and Facial Nerves in the Posterior Fossa under Endoscope-Assisted Keyhole Conditions
2008
Objective: The aim of this study was to determine the use and safety of the endoscope as an adjunct during trigeminal and facial nerve decompression procedures performed under keyhole conditions in the posterior fossa. Method: We performed 67 surgeries in 65 patients with symptomatic trigeminal and facial nerve compression syndromes. The diagnosis was made mainly on the basis of clinical history, examination, and magnetic resonance imaging scans. Surgery was performed in all cases under endoscope-assisted keyhole conditions. The follow-up was 1 week postoperatively, 6 months, and then yearly up to 7 years. All 34 patients with trigeminal neuralgia received preoperative medication treatment …
