PURPOSE: Hyperextension-distraction type injury of the thoracolumbar spine is an unstable fracture pattern that generally necessitates surgical stabilization by posterior instrumentation. Care must be taken when positioning these patients from supine to prone due to the unstable nature of their injury. The study objectives were (1) to describe a novel modification of the Jackson table turn technique, which may be safer and more effective than the conventional log-roll method and traditional Jackson table technique for positioning patients with hyperextension-distraction injuries of the thoracolumbar spine from supine to prone in the operating room and (2) to present two cases in which this technique was successfully performed...

Background: Meningioma patients are known to face cognitive deficits before and after surgery. We examined individual changes in cognitive performance over time and identified preoperative predictors of cognitive functioning 12 months after surgery in a large sample of meningioma patients. Methods: Patients underwent neuropsychological assessment (NPA) using CNS Vital Signs 1 day before (T0), and 3 (T3) and 12 (T12) months after surgery. Patients' sociodemographically-corrected scores on 7 cognitive domains were compared to performance of a normative sample using one-sample z tests and Chi-square tests of independence...

Noxious stimuli induce a nociceptive withdrawal reflex (NWR) to protect the tissue from injury. Although the NWR was once considered as a stereotyped response, previous studies report distinct responses depending on the stimulation site and context for limbs. We aimed to determine whether noxious stimuli over the trunk produced adaptable complex NWR. We hypothesized that organization of the NWR of the trunk muscle would vary with the site of noxious input and would differ between body and spine postures, which modify the potential for specific muscles to remove threat...

TBA is a 15-mer DNA aptamer for human α-thrombin, and its three T-rich loops are involved in the binding interactions with thrombin differently. In order to clarify their specific spatial locations in the binding interactions and search for more favourable positions, here a systematic investigation of all the loop residues was conducted with 3'-inverted thymidine (iT), by which both unnatural 3'-3'- and 5'-5'-linkages for each incorporation were introduced in the tertiary structure. The changes in Tm values and CD spectra revealed that motifs T3T12 and T4T13 are structurally distinct...

OBJECTIVE: To compare the esthetic improvement between postorthodontic white-spot lesions (WSLs) treated by resin infiltration and microabrasion for 12 months. MATERIALS AND METHODS: A total of 20 patients with 128 teeth with postorthodontic WSLs were recruited. A simple randomized, split-mouth, positive controlled design was used to allocate patients to resin infiltration or microabrasion groups. The lesion area ratio (R value) was calculated between the area of a WSL and the labial surface of the corresponding tooth based on standardized clinical photographs...

The majority of compressive vertebral fractures in osteoporotic bone occur at the level of the thoracolumbar junction. Immediate decompression is often required in order to reduce the extent of neurological damage. This study evaluated four fixation methods for decompression in patients with thoracolumbar burst fractures, and presented the most suitable method for osteoporotic patients. A finite element model of a T7-L5 spinal segment was created and subjected to an L1 corpectomy to simulate a serious burst fracture...

In major depressive disorder (MDD) patients, life stress events represent a risk factor for a severe, early-onset, treatment-resistant and chronic endophenotype. Treatment-resistant depression (TRD) patients who have experienced traumatic events could benefit from evidence-based trauma-focused psychotherapies. Because this topic has never been investigated, the aim of this pilot trial was to evaluate whether trauma-focused cognitive-behavioural therapy (TF-CBT) and/or eye movement desensitization and reprocessing (EMDR) can help achieve depressive symptom remission in TRD patients...

PURPOSE: Thoracic disk herniation (TDH) is relatively uncommon. The surgical approach differs from lumbar or cervical disk herniations because serious complications are associated with the posterior approach in TDH. Various different approaches have been tried for the surgical removal of TDH, but most of them are cumbersome surgeries such as thoracotomy or thoracoscopic or anterior approaches with or without instrumentation. The requirement for a simplified, familiar, and less morbid surgery has motivated some new approaches...

RATIONALE: Spinal epidural abscess (SEA) is a rare condition that shows a high prevalence in immunocompromised patients. The clinical presentation of SEA includes the "classic triad" of pain, fever, and neurological dysfunction. However, these nonspecific features can lead to a high rate of misdiagnosis. SEA may lead to paralysis or even death; thus, prognosis of these patients remains unfavorable. PATIENT CONCERNS: We report a case of a multilevel (T6-T12) SEA in a 22-year-old woman...

Calcitonin gene-related peptide (α-CGRP) released from perivascular sensory nerves induces decreases in diastolic blood pressure (DBP). Experimentally, this can be shown by spinal thoracic (T9-T12) electrical stimulation of these afferent fibers. Since ergotamine inhibits these neurogenic vascular responses and displays affinity for monoaminergic receptors that inhibit neurotransmitter release, the present study investigated whether this ergotamine-induced inhibition results from activation of serotonin 5-HT1B/1D, dopamine D2-like and α2-adrenergic receptors...

PURPOSE: Body composition is of great prognostic value in several severe diseases, including different types of cancer as well as cardiometabolic disorders. We aimed to investigate the correlations of skeletal muscle mass and abdominal adipose tissue compartments between volumetric and single-slice measurements to study the usefulness of several anatomical landmarks for estimation of total compartment volumes using abdominal CT-scans. METHODS: In this retrospective study volumetric quantifications of paraspinal skeletal muscles (SM) and adipose tissue compartments (visceral adipose tissue, VAT; subcutaneous adipose tissue, SAT) were performed in 50 consecutive patients (26 male; mean age, 63 ± 15 years) who underwent abdominal multislice-CT for diagnostic purposes using an in-house software...

Greater kyphosis angles lead to increased loading on vertebral bodies in computational models. However, results about the relationship between severity of kyphosis and incident vertebral fracture (VF) risk have been conflicting. Therefore, the aim of this study was to evaluate associations between a) prevalent VFs and severity of kyphosis, and b) severity of kyphosis and incident VF risk, in smokers with or without COPD. Former and current smokers with or without COPD were included. CT scans were made at baseline, one-year and three-year follow-up...
