The present study reports the case of an 81-year-old woman who underwent lumboperitoneal shunt (LPS) placement for idiopathic normal-pressure hydrocephalus. After LPS placement, the patient presented with radicular pain. A computed tomography scan revealed that the intradural lumbar catheter was tangled at the T11 vertebra; therefore, we decided to remove the catheter under local anesthesia. When 1 cm of the lumbar catheter was withdrawn, the patient suddenly complained of complete loss of bilateral leg sensation and muscle strength...

There is little evidence for the involvement of microRNAs (miRNAs) in the regulation of circadian rhythms during enamel development. Few studies have used ameloblast-like cell line LS8 to study the circadian rhythm of gene activities related to enamel formation. However, the transcriptomic analysis of miRNA expression in LS8 cells has not been established yet. In this study, we analyze the oscillations of miRNAs in LS8 cells during one-day cycle of 24 h by next generation deep sequencing. After removal of low quality reads, contaminants, and ligation products, we obtained a high number of clean reads in all 12 samples from four different time points...

Background: Despite widespread use by manual therapists, there is little evidence regarding the reliability of thoracic spine static palpation to test for a manipulable lesion using stiffness or tenderness as diagnostic markers. We aimed to determine the interrater agreement of thoracic spine static palpation for segmental tenderness and stiffness and determine the effect of standardised training for examiners. The secondary aim was to explore expert consensus on the level of segmental tenderness required to locate a "manipulable lesion"...

BACKGROUND: Reconstruction of complex back defects, especially after corrective spine surgery, is a challenging problem. In these patients hardware issues predominate and flap failure has serious consequences. Certain subunits of the back pose even greater problems, specifically the central region between T9 and T12. The purpose of this article is to present a novel technique for reconstruction of such spinal defects using a newly described trapezius muscle propeller flap based on the dorsal scapular vessels...

There is an imperative need for effective control of bovine tuberculosis (BTB) on a global scale and vaccination of cattle may prove to be pivotal in achieving this. The oral and parenteral use of a heat-inactivated Mycobacterium bovis (M. bovis) vaccine has previously been found to confer partial protection against BTB in several species. A role for complement factor C3 has been suggested in wild boar, but the exact mechanism by which this vaccine provides protection remains unclear. In the present study, a quantitative proteomics approach was used to analyze the white blood cell proteome of vaccinated cattle in comparison to unvaccinated controls, prior (T0) and in response to vaccination, skin test and challenge (T9 and T12)...

Spontaneous intracranial hypotension (SIH), caused by CSF leaks, can trigger headaches, and is treated using epidural blood patch (EBP) procedures. We aimed to determine the effectiveness of a newly devised two-site blind EBP procedure as the initial treatment for SIH and compare its effectiveness with that of conventional targeted EBP. We retrospectively reviewed data for 116 patients who underwent EBP for SIH between November 2013 and April 2017. Patients were divided into two groups: those who initially received two-site blind EBP (n = 28) at the cervicothoracic (C7/T1) and thoracolumbar junctions (T12/L1) for sealing CSF leaks at all levels, and those who received targeted EBP after CT myelography (n = 88)...

OBJECTIVEThe surgical correction of adult spinal deformity (ASD) often involves modifying lumbar lordosis (LL) to restore ideal sagittal alignment. However, corrections that include large changes in LL increase the risk for development of proximal junctional kyphosis (PJK). Little is known about the impact of cranial versus caudal correction in the lumbar spine on the occurrence of PJK. The goal of this study was to investigate the impact of the location of the correction on acute PJK development.METHODSThis study was a retrospective review of a prospective multicenter database...

Background: Acute pancreatitis has been described as potential complication of both abdominal and non-abdominal surgeries. The pathogenetic mechanism underlying acute pancreatitis in spine surgery may include intraoperative hemodynamic instability causing prolonged splanchnic hypoperfusion, as well as mechanical compression of the pancreas due to scoliosis correction, with a higher risk in cases of more extended fusions, especially in young adults with lower body mass index (BMI). Case presentation: We report here a case of postoperative acute pancreatitis with benign evolution in a young female patient after the first and second surgery of a two-stage correction of right thoracic idiopathic scoliosis...

Alzheimer's disease (AD) is a fatal dementing neurodegenerative disease, currently lacking an efficacious disease-modifying therapy. In the last years, there has been some interest in the use of homotaurine as a potential therapeutic compound for AD, but more work is still needed to prove its efficacy as disease modifier in dementia. Since inflammation is believed to play a key role in AD development, we sought to investigate here the in vivo homotaurine effect on inflammatory response in patients at the earliest stages of AD, i...

Ginsenoside Compound K (CK) showed potent activity against IgE for the treatment of asthma. A series of CK analogues were then synthesized by straightforward procedures. The in vivo anti-IgE activity evaluations using the OVA-induced asthmatic mouse model revealed preliminary SARs of the CK analogues, which showed that the sugar type, modifications on A-ring and the C20 side chain of CK all affected much on the activities. Primary SARs optimization led to the discovery of compounds T1, T2, T3, T8 and T12, which displayed superior or comparable anti-asthmatic effects (IgE value = 1237...

PURPOSE: Detailed knowledge of the anatomy of the thoracic aorta is crucial for thoracolumbar spinal surgery. The purpose of the present study is to describe the relative displacement of the aorta to the spine in supine, prone and prone position with padding. Improved understanding of the magnitude and direction of this often-overlooked change could benefit preoperative planning and decision-making. METHODS: A total of 200 patients underwent CT scan of the thoracic spine in the standard supine, prone and prone position with padding...
