PURPOSE The purpose of this study is to identify the subgroups of thyroid eye disease (TED) patients most likely to benefit from orbital fat decompression. METHODS This retrospective study reviews 217 orbits of 109 patients who underwent orbital fat decompression for proptosis secondary to thyroid eye disease. Charts were reviewed for demographic, radiographic, clinical, and surgical data. Th...

STUDY DESIGN Systematic review. OBJECTIVE To identify whether there is an advantage to instrumented or noninstrumented spinal fusion over decompression alone for patients with degenerative lumbar spondylolisthesis. SUMMARY OF BACKGROUND DATA The operative management of degenerative spondylolisthesis includes spinal decompression with or without instrumented or noninstrumented spinal fusion....

OBJECTIVE To examine whether use of the active compression-decompression device improves the haemodynamics of cardiopulmonary resuscitation compared with those of conventional cardiopulmonary resuscitation. DESIGN Prospective crossover study. SETTING The accident and emergency department of a university teaching hospital. PATIENTS 36 adult patients with non-traumatic, normothermic, out of...

A mixed-gas model for rats was developed to further explore the role of different gases in decompression and to provide a global model for possible future evaluation of its usefulness for human prediction. A Hill-equation dose-response model was fitted to over 5,000 rat dives by using the technique of maximum likelihood. These dives used various mixtures of He, N(2), Ar, and O(2) and had times ...

BACKGROUND Symptomatic labral tears of the hip are associated with bony abnormalities of the femoral head and acetabulum, resulting in impingement. These patients have characteristic internal rotation limitations, which can result in compensatory athletic injury patterns around the hip, pelvis, and lumbar spine. HYPOTHESIS Patients undergoing arthroscopic cam decompression will have improveme...

Compression techniques are widely used to reduce the amount of memory that is needed to store data. A common scenario is the use of compressed data on a secondary storage device. For subsequent access, data has to be retrieved and decompressed. One might assume that the additional decompression step implies a performance penalty. However, a careful selection of a suitable compression method and...

Patients with obstructive jaundice are prone to septic complications after biliary tract operations. Restoring bile flow to the intestine may help to decrease the complication rate. The present study is aimed at evaluating the effect of biliary decompression on bacterial translocation in jaundiced rats. Sixty-six male Sprague-Dawley rats were randomly allocated to six groups subjected to common...

OBJECTIVE To test the hypothesis whether enriched air nitrox (EAN) breathing during simulated diving reduces decompression stress when compared to compressed air breathing as assessed by intravascular bubble formation after decompression. METHODS Human volunteers underwent a first simulated dive breathing compressed air to include subjects prone to post-decompression venous gas bubbling. Twel...

1. Muscular activity during decompression causes bubble formation in the blood of intact bullfrogs. The amount of gas liberated depends on the degrees of muscular activity and supersaturation (as influenced by altitude). In decompressed dissected bullfrogs, bubbles appear in veins leading from active but not from inactive muscles. 2. Muscular activity during decompression similarly causes bubbl...

STUDY DESIGN Prospective study conducted at Jawaharlal Nehru Medical College, Datta Meghe Institute of Medical Sciences, Wardha, India. PURPOSE To show the efficacy of decompression in the late presentation of cervical spinal cord disorders. OVERVIEW OF LITERATURE Studies by various authors have shown that early spinal decompression results in better neurological outcomes. METHODS From Ja...
