Impact of gas emboli and hyperbaric treatment on respiratory function of loggerhead sea turtles (Caretta caretta)

2018

We investigated lung function in bycaught sea turtles with and without gas emboli. Hyperbaric O2 treatment significantly improves lung function. Pulmonary function testing may be a useful diagnostic tool to assess fisheries induced trauma.

Magnetic resonance findings in scuba diving-related spinal cord decompression sickness

1997

Scuba diving is associated with risk of severe decompression sickness (DCS type II), which results from rapid reduction of the environmental pressure sufficient to cause the formation into tissue or blood of inert gas bubbles previously loaded within tissues as a soluble phase. DCS type II constitutes a unique subset of ischemic insults to the central nervous system (CNS) with primarily involvement of the spinal cord. Ten patients with diving-related barotrauma underwent neurologic examination. Two of them presented progressive sensory and motor loss in the extremities at admission and were presumed affected by spinal cord DCS. Magnetic resonance imaging (MRI) demonstrated abnormalities in …

Cisternostomy for Traumatic Brain Injury: Pathophysiologic Mechanisms and Surgical Technical Notes

2016

Objective Traumatic brain injury (TBI) is one of the major challenges in health care, representing the third most frequent cause of death. Current optimal management is based on a progressive, target-driven approach combining both medical and surgical treatment strategies. Here we describe cisternostomy, an emerging surgical treatment for the treatment of TBI. Methods Cisternostomy is a novel technique that incorporates knowledge of skull base and microvascular surgery. By opening the brain cisterns to atmospheric pressure, the technique could decrease the intracranial pressure due to a backshift of the cerebrospinal fluid (CSF) from the swollen brain to the cisterns through the Virchow-Rob…

Surgical Treatment in Symptomatic Chiari Malformation Type I: A Series of 25 Adult Patients Treated with Cerebellar Tonsil Shrinkage

2019

Background: The variety of symptoms and radiological findings in patients with Chiari malformation type I makes both the indication for surgery and the technical modality controversial. We report our 5-year experience, describing our technique and critically evaluating the clinical results. Methods: Between 2012 and 2016, 25 patients (15 female and 10 male; mean age 39.2 years) underwent posterior fossa decompression for Chiari malformation type I. Their clinical complaints included headache, nuchalgia, upper limb weakness or numbness, instability, dizziness and diplopia. Syringomyelia was present in 12 patients (48%). Suboccipital craniectomy was completed in all cases with C1 laminectomy …

Clinical analysis following lumbar interspinous devices implant: where we are and where we go

2014

Objectives:We present our experience with patients treated with interspinous devices who are affected by neurogenic intermittent claudication (NIC) or lumbar disc herniation (LDH) where the interspinous system has been inserted following microdiscectomy.Study design:Retrospective study.Methods:This study included patients (n=100) with NIC secondary to lumbar spinal stenosis (group 1), and patients (n=100) with LDH (group 2) in whom the interspinous device has been implanted following radicular decompression in a period spanning 6 years. The latter have been compared with a homogenous group of patients (n=100) where no interspinous system has been implanted following microdiscectomy (group 3…

Cervical Spondylotic Myelopathy: When and Why the Cervical Corpectomy?

2020

Background: Cervical spondylotic myelopathy (CSM) is a degenerative disease that represents the most common spinal cord disorder in adults. The best treatment option has remained controversial. We performed a prospective study to evaluate the clinical, radiographic, and neurophysiologic outcomes for anterior cervical corpectomy in the treatment of CSM. Methods: From January 2011 to January 2017, 60 patients with CSM were prospectively enrolled in the present study. The patients were divided according to the modified Japanese Orthopaedic Association scale (mJOA) score into 2 groups: group A, patients with mild to moderate CSM (mJOA score ≥13); and group B, patients with severe myelopathy (mJ…

Operative management of epidural tumors of the spine

1994

Seventy-two patients with neoplastic involvement of the vertebral column were operated on between 1986 and 1991. In the course of 79 operations anterior decompression and stabilization alone were performed in 3 cases, while ventrodorsal spondylodesis was carried out in 10 individuals. The remainder of the patients underwent exclusively dorsal decompression and stabilization, mainly with the Cotrel-Dubousset instrumentation (CDI). No external spinal support was required following posterior fixation by CDI alone or in combination with ventral spondylodesis. Forty patients suffered from neurological deficits preoperatively, 20 of them being unable to walk, in most cases owing to severe vertebr…

Intraparenchymal Brain Hemorrhage: "Birdlime" Effect Usefulness.

2018

The authors previously reported the novel transposition techniquefor microvascular decompression (MVD) using a tissue glue-coated collagen sponge (TachoSil Tissue Sealing Sheet; CSLBehring KK, Tokyo, Japan) soaked withfibrin glue (Tisseel 2-Component Fibrin Sealant, Vapor-Heated; Baxter Healthcare,Glendale, California, USA), termed the“birdlime”technique

Severe odontogenic infection: An emergency. Case report

2017

Odontogenic infections (OI) are a major reason for consultation in dental practice. They affect people of all ages, and most of them respond well to current medical and surgical treatments. However, some OI can spread to vital and deep structures, overcome the host immune system - especially in diabetic, immunocompromised or weakened patients - and even prove fatal. Ludwig's angina is a severe form of diffuse cellulitis that can have an acute onset and spread very rapidly, bilaterally affecting areas of the head and neck, and may prove life threatening. A case of severe dental infection is presented in which emphasis is placed on the importance of airway maintenance, followed by surgical de…
