Thickening of the LF is correlated with disc degeneration, aging, BMI, LSS, spinal level, and disc herniation. The authors concluded that thickening of the LF is due to buckling of the LF into the spinal canal secondary to disc degeneration more than to LF hypertrophy. Sex and the degree of pain were not correlated with the thickness of the LF.
Background:Anaplastic astrocytoma (AA; WHO grade-III) patients determination of prognostic factors helps generating multimodal therapy protocols. For this purpose, in the Baskent University, Adana Medical Research Center, specific characteristics of AA patients who have surgery were retrospectively investigated and factors which affect prognosis has been determined.Patients and Methods:Between January 2005 and 2009, 20 patients who have AA have been evaluated retrospectively. Totally, 20 patients had 31 operations. Sixteen patients had only adjuvant radiation therapy (RT). In the postoperative period, 8 patients received adjuvant RT. Nine of 10 patients with tumor recurrence received concomitant therapy with temozolomide (ConcT with TMZ) protocol. No adjuvant therapy protocol could be applied in three patients with poor general condition in the postoperative period.Results:Median survival for patients died was 16±17 months; one year survival was 75% and five year survival 25%. After univariate analysis, preoperative Karnofsky performance score (KPS) was ≥80 (P=0.005577*), postoperative KPS was ≥80 (P=0.003825*), type of tumor resection (P=0.001751*), multiple operations (P=0.006233*), and ConcT with TMZ protocol (P=0,005766*) were all positive prognostic factors which extend the survival.Conclusions:The results of the multivariate analysis did not put forward an independent prognostic factor acting on the survival period (P>0.05).
Idiopathic ventral spinal cord herniation is a rare cause of progressive myelopathy that demonstrates unique radiological features. We describe a case of thoracic spinal cord herniation through an anterior dural defect and discuss the characteristic findings on magnetic resonance imaging and computed tomographic myelography. A 36-year-old man presented to our clinic with progressive leg weakness and spasticity in both legs. Magnetic resonance imaging of the thoracic spinal canal demonstrated C-shaped anterior kinking of an atrophied spinal cord and enlarged dorsal subarachnoid space at the T5-T6 level. Computed tomographic myelography showed ventral herniation of the spinal cord and no evidence of an intradural spinal arachnoid cyst. Ventral spinal cord herniation is a commonly misdiagnosed entity. Knowledge of the characteristic imaging appearance of this treatable condition is important for proper diagnosis and treatment.
We suggest that E-selectin is as valuable as the other well-known inflammatory markers in the pathogenesis of LDH. In our opinion, beside the well-known nonsteroidal anti-inflammatory drugs, antagonists targeting E-selectin can be potentially effective therapeutics for controlling inflammation in LDH.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
