“Study Design. A retrospective study had been conducted this website to compare the existing preoperative scoring systems and to find useful prognostic factors for patients with spinal metastases from hepatocellular carcinoma (HCC).
Objective.
To evaluate different preoperative scoring systems and prognostic factors for patients with spinal metastases from HCC.
Summary of Background Data. Different scoring systems for metastatic spinal tumor have been designed for prognostic evaluation. However, these scoring systems were formulated from many different types of tumors, so that their efficacy for a certain type of cancer needs to be validated. Furthermore, some serologic test results may enhance the accuracy of the scoring system.
Methods. We conducted a retrospective study to evaluate 4 prognostic scoring systems and factors in a series of 41 cases with spinal metastases from HCC in a single center. These scoring systems include Tokuhashi revised score, Tomita score, Bauer score, and a revised van der Linden score by the authors. Serologic test items including serum albumin, aspartate aminotransferase, alanine transaminase, and lactate dehydrogenase (LDH) were also evaluated.
Results. The revised Tokuhashi scoring system provided statistically significant differences in survival time
between different groups (P = 0.012), while the Tomita and Bauer systems did not show statistically significant differences (P = 0.918 and P = 0.754, respectively). Significantly improved survival was found in patients with good performance Ion Channel Ligand Library price status and no visceral metastases (Group C, P = 0.008) in revised van der Linden scores. Univariate and multivariate analyses showed serum albumin and LDH were independent prognostic factors for survival time.
Conclusion. Revised Tokuhashi scoring system is practicable and highly predictive, while serum albumin and LDH also have
prognostic value in patients with spinal metastases from HCC, especially those without visceral metastases. More accurate prognosis may be obtained if the scoring systems include clinical and laboratory data in future.”
“PURPOSE: click here To evaluate an algorithm for corneal power estimation in intraocular lens (IOL) power calculation after myopic laser refractive surgery using direct corneal measurements.
SETTING: International Vision Correction Research Centre, University of Heidelberg, Heidelberg, Germany.
METHODS: Corneal parameters in normal eyes and eyes of refractive surgery cases were evaluated by rotating Scheimpflug imaging. Corneal optical power (K(optical)) calculated by a Gaussian optics formula was simplified as K(optical) = K(anterior) + K(2) (K(anterior) = anterior corneal power; K(posterior) posterior corneal Power; K(2) = K(posterior) – K(anterior) X K(posterior) X corneal thickness/1.
