Discal Cyst of the Lumbar Spine

Discal cysts of the lumbar spine: report of five cases and review of the literature

“…This finding was not demonstrated in intervertebral disc herniation and other intraspinal cysts [8,18]. Thus, this review shows that contrast flow into the disc demonstrated by discography is pathognomic, and this investigation is diagnostic for these lesions.…”

“…Moreover, in cases of doubtful diagnosis, surgery is performed to relieve the compression of the neural structures, as surgical treatment leads to symptom improvement, regardless of its origin [8,18]. In addition, intraoperative findings of the apparent connection between the corresponding disc and the cyst are also possible to differentiate discal cysts from other intraspinal cysts [8,21]. For these reasons mentioned above, we did not perform discography, and MRI was satisfactory for the management of the patients in our series.…”

“…MRI is very sensitive in the diagnosis of discal cysts, non-invasive, and better in demonstrating the relation of these lesions with the surrounding structures. Moreover, in cases of doubtful diagnosis, surgery is performed to relieve the compression of the neural structures, as surgical treatment leads to symptom improvement, regardless of its origin [8,18]. In addition, intraoperative findings of the apparent connection between the corresponding disc and the cyst are also possible to differentiate discal cysts from other intraspinal cysts [8,21].…”

Differential Argentometric Titration Equipped with a Reflectance Detector for the Determination of Halogen Anions

“…The bigger jump of the last step may be due to the exponential relationship bet-ween the reflected light and the concentration of an analyte. 8 The number of steps formed in the second part of the curve was counted to be 7 and the concentration of Br -ion in the mixture was found to be 1.94 mM. Figure 2-(b) shows the titration curve obtained with a mixture of [Br -] = 2.00 mM and [I -] = 4.00 mM and reveals the similar pattern as the curve shown in Figure 2-(a).…”

“…While several methods for the determination of halide ions in aqueous samples using electrochemical, 1-3 optical, 4 and chromatographic [5][6][7] techniques have been reported, they all require sophisticated devices and involve complex procedures. The method presented in this paper introduces a relatively simple technique utilizing a stopped flow argentometric titration system equipped with a reflection detector [8][9][10][11][12] for the analysis of aqueous binary mixtures of Br -and I -ions.…”
