The relationship between prolonged cerebral oxygen desaturation and postoperative outcome in patients undergoing coronary artery bypass grafting.
58 patients who underwent on-pump coronary artery bypass graft surgery were evaluated for changes in regional cerebral oxygen saturation (rSO2) measured by near infrared spectroscopy (NIRS). If rSO2 during the operation fell to more than 20% under the baseline, standardized interventions were undertaken to maintain rSO2. Despite those interventions, in some cases we observed inability to maintain rSO2 above this threshold. ⋯ Three patients in prolonged desaturation group and no one in another group had stroke, coma or stupor (p=0.03). Logistic regression analysis revealed diabetes mellitus and age as predictors for prolonged rSO2 desaturation. We concluded that prolonged intraoperative rSO2 desaturation is significantly associated with worse neurological outcome in patients - nonresponders to standardized interventions for prevention of rSO2 desaturation.

Alterations in the masseter muscle and plasma IL-6 level following experimentally induced occlusal interference and chronic stress--a study in rats.
This study was undertaken to examine the alteration of masseter and plasma interleukin-6 after inducing occlusal interference and chronic stress. Male Wistar rats were submitted to chronic stress procedure, exposed to occlusal interference, or exposed to both mentioned procedures. Whole blood and masseter tissue were collected to determine interleukin-6 level, measured by means of ELISA. ⋯ No significant differences in plasma interleukin-6 level were found between groups (p>0.05), as well as no correlation with pain (p>0.05). Combination of occlusal interference and chronic stress leads to strong local reaction characterized by high levels of masseter interleukine-6. High concentrations of muscle interleukin-6 and its correlation with pain point to inflammatory background of masticatory muscle pain.

Randomized Controlled Trial Comparative StudySpinal anesthesia at the L2-3 and L3-4 levels: comparison of analgesia and hemodynamic response.
Aim of this study was to evaluate level of analgesia and hemodynamic response to spinal anesthesia obtained by administering 15 mg 0.5% isobaric bupivacaine at L2-3 vs. L3-4 interspace for inguinal herniorrhaphy, since studies comparing analgesia and hemodynamic response at the L2-3 vs. L3-4 interspaces are lacking. ⋯ L3-4 17%, 95% CI 0.07-0.32) and bradycardia (L2-3 19%, 95% CI 0.09-0.35 vs. L3-4 8%, 95% CI 0.02-0.23). Spinal anesthesia with isobaric bupivacaine administered in L2-3 interspace for inguinal herniorrhaphy provides superior analgesia and equal hemodynamic stability as compared to neuroaxial anesthesia administered in the L3-4 interspace.

Clinical TrialMeasurement of spinal sagittal curvatures using the laser triangulation method.
The purpose of the first part of the study was to establish the variability of repeated measurements in different measuring conditions. In the second part, we performed in a large number of patients, a measurement of thoracic kyphosis and lumbar lordosis and compared them to age, gender, and level of nourishment. In the first part, measurements were performed on a plastic model of the back of a patient with a rigid and a normal spine. ⋯ During measurements of the spinal angles it was important to pay attention to relaxation and the patient's position as well as to perform more measurements providing the average value. The age and the level of nourishment influence the size of the sagittal spinal angles. In the observed sample the effect of age was not confirmed.

A probable case of Hand-Schueller-Christian's disease in an Egyptian mummy revealed by CT and MR investigation of a dry mummy.
The challenging mission of paleopathologists is to be capable to diagnose a disease just on the basis of limited information gained by means of one or more paleodiagnostic techniques. In this study a radiologic, anthropologic and paleopathologic analysis of an ancient Egyptian mummy through X-rays, CT and MR was conducted. An Ancient Egyptian mummy ("Mistress of the house", Archeological Museum, Zagreb, Croatia) underwent digital radiography, computed tomography and magnetic resonance imaging employing 3-dimensional ultra-short-echo time (UTE) sequence, that allows to image ancient dry tissue. ⋯ The mummification techniques used and radiometric data (C14) dated it to 900-790.
