[Early detection of asymptomatic dysbaric osteonecrosis of the shoulder after type 1 decompression sickness: a case report].

Dysbaric osteonecrosis by X-ray and CT scan in Chinese divers.

OBJECTIVE To compare the results of X-ray and CT scan for dysbaric osteonecrosis in Chinese divers. METHODS Both shoulders, hips and knees of 66 asymptomatic divers with diving duration of more than one year were examined by X-ray and CT scan. RESULTS The most frequent locations of dysbaric osteonecrosis were the upper femurs, followed by the upper humerus, lower femurs and upper tibias, an...

Aseptic necrosis of the femoral head after pregnancy: a case report

A documented case of beginning aseptic necrosis of the femoral head associated with pregnancy together with a review of the literature about this rare complication of pregnancy is presented. The known risk factors of osteonecrosis are; steroid use, alcoholism, organ transplantation, especially after kidney transplant or bone marrow transplantation bone, systemic lupus erythematosus, dyslipidemi...

The use of Diagnostic Imaging for Identifying Abnormal Gas Accumulations in Cetaceans and Pinnipeds

Recent dogma suggested that marine mammals are not at risk of decompression sickness due to a number of evolutionary adaptations. Several proposed adaptations exist. Lung compression and alveolar collapse that terminate gas-exchange before a depth is reached where supersaturation is significant and bradycardia with peripheral vasoconstriction affecting the distribution, and dynamics of blood an...

Extravascular Hydrophobic Surfaces, Fat Droplets, and the Connection With Decompression Illness: Spinal, Joint Pain, and Dysbaric Osteonecrosis

Comparison of Total Hip Arthroplasty and Core Decompression in Avascular Necrosis of the Femoral Head after Taking Temgesic and Norgesic

Background: Osteonecrosis is common after taking Temgesic and Norgesic. This study intended to suggest the preferable surgical treatment in osteonecrosis patients who use these drugs. Methods: Twenty tree patients with hip osteonecrosis who were hospitalized in the Kerman hospitals after using Temgesic and Norgesic were followed for about 14 months from 2008 to 2010 (from a minimum of 2 months ...
