BACKGROUND Surgical outcomes after orbital wall decompression have focused on the degree of exophthalmos and intraocular pressure. The aim of this research was to evaluate intraorbital volume using computed tomography (CT) images following two-wall decompression using a combined subcilliary and endoscopic approaches. METHODS A retrospective review was performed for all patients who had underg...

by T.J.R. Francis, D.J. Smith and J.J. W. Sykes, Institute of Naval Medicine, Hampshire, England. The current means by which we classify decompression sickness dates back only 30 years to the experience gained during the construction of the Dartford Tunnel in London. Golding et al [1] proposed a system for decompression sickness based upon perceived severity of the cases which arose in the cais...

Diving-related decompression illness is classified into 2 main categories: arterial gas embolism and decompression sickness. The latter is further divided into types 1 and 2, depending on the clinical presentation. MR imaging is currently the most accurate neuroimaging technique available for the detection of brain and spinal cord lesions in neurologic type 2 decompression sickness. Rapid bubbl...

Core decompression for avascular necrosis (AVN) of the femoral head continues to be a controversial procedure. Meta-analysis techniques were employed to identify 22 studies with a single surgical core decompression technique. A similar procedure identified eight studies that treated patients conservatively. The success rates for core decompression were 84%, 63%, and 29% for Steinberg stages I, ...

Eftedal OS, Lydersen S, Brubakk AO. The relationship between venous gas bubbles and adverse effects of decompression after air dives. Undersea Hyperb Med 2007; 34(2):99-105.The presence of gas bubbles in the vascular system is often considered a sign of decompression stress and several studies in the existing literature have addressed the relationship between the amount of bubbles detected by u...

Each year, over 45 countries export 30 million fish from coral reefs as part of the global marine ornamental aquarium trade. This catch volume is partly influenced by collection methods that cause mortality. Barotrauma in fish resulting from forced ascent from depth can contribute to post-collection mortality. However, implementing decompression stops during ascent can prevent barotrauma. Conve...

STUDY DESIGN Retrospective. PURPOSE To report the outcomes of patients with lumbar spinal stenosis treated with percutaneous endoscopic decompression, focusing on the results of clinical evaluations. OVERVIEW OF LITERATURE There are no studies about two portal percutaneous endoscopic decompression in the treatment of lumbar spinal stenosis. METHODS Medical and surgical complications were ...

Isolated inner ear decompression sickness (DCS) is recognized in deep diving involving breathing of helium-oxygen mixtures, particularly when breathing gas is switched to a nitrogen-rich mixture during decompression. The biophysical basis for this selective vulnerability of the inner ear to DCS has not been established. A compartmental model of inert gas kinetics in the human inner ear was cons...

Degenerative Scoliosis is well known for producing both neurological and mechanical symptoms in addition to deformity sometimes instability. Decompression alone has been treatment of choice patients with mild neurogenic claudication or radiculopathy but without However, fusion preferred counter deformity, instability forces. We intended study these variables when treated decompression alone. ev...

BACKGROUND Nerve decompression has been recently described as a therapy for migraine headaches. Multiple studies have demonstrated significant symptomatic relief or complete resolution of migraine symptoms in patients with surgical decompression. However, there is no study describing a causal relation between migraine headaches and nerve compression and resolution of symptoms with tumor removal...
