BACKGROUND Lumbar disc removal is currently the standard treatment for lumbar disc herniation. No consensus has been achieved whether aggressive disc resection with curettage (discectomy) versus conservative removal of the offending disc fragment alone (sequestrectomy) provides better outcomes. This study aims to compare the reherniation rate and clinical outcomes between discectomy and sequest...
Introduction: Intralobar pulmonary sequestration [ILS] is overall the most common form of Bronchopulmonary sequestration (BPS) commonly presenting as consolidation in the lower lung lobes. Methods: A young male (23 years) presented with hemoptysis and a large cavity with air fluid level in the left lower lung lobe for 6-7 years. Computed Tomography of chest and bronchoscopy were inconclusive an...
Using a local model Gammie (2001) has shown that accretion discs with cooling times tcool ≤ 3Ω −1 fragment into gravitationally bound objects, while those with cooling times tcool > 3Ω −1 evolve into a quasi-steady state. We use three-dimensional smoothed particle hydrodynamic simulations of protoplanetary accretion discs to test if the local results hold globally. We find that for disc masses ...
It is a general rule that of two complementary Drosophila imaginal disc fragments, one regenerates and the other duplicates. This paper reports an investigation of an exception to this rule. Duplicating fragments from the periphery of the wing disc which lacked presumptive notum were found to regenerate notum structures during and after duplication. The propensity for this was greatest in fragm...
Lumbar disc herniation is the most common diagnosis among the degenerative abnormalities of the lumbar spine (affecting 2 to 3% of the population), and is the principal cause of spinal surgery among the adult population. The typical clinical picture includes initial lumbalgia, followed by progressive sciatica. The natural history of disc herniation is one of rapid resolution of the symptoms (fo...
A 32-year-old man underwent radiofrequency thermal annuloplasty (TA) with percutaneous endoscopic discectomy (PED) under local anesthesia for chronic low back pain. His diagnosis was discogenic pain with a high signal intensity zone (HIZ) in the posterior corner of the L4-5 disc. Flexion pain was sporadic, and steroid injection was given twice for severe pain. After the third episode of strong ...
OBJECTIVES To evaluate the percentage of disc hernias that have disappeared after one year of follow-up and the time to disappearance. To determine whether gadolinium enhancement is useful for predicting whether the hernia will disappear. To analyze whether the pattern of enhancement can help predict whether the fragment will disappear. MATERIAL AND METHODS This prospective study included 118...
purpose: to present a patient with localized corneal edema due to a small retained fragment of nucleus in the anterior chamber after uncomplicated phacoemulsification. case report: a 74-year-old female subject with history of phacoemulsification in her right eye about 1.5 years ago complained of foreign body sensation, pain and decreased vision in the same eye. visual acuity of that eye had dec...
A 60-year-old woman complained of low back pain radiating to both buttocks and to the anterior aspect of the left thigh. MRI showed a left posterolateral epidural mass at the L1-L2 level. An epidural abscess was suspected, but the biochemistry was normal. Excision yielded complete relief of symptoms. Pathological examination demonstrated that the specimen was a migrated disc fragment. The autho...
