Daytime blue light exposure can reduce fatigue and increase alertness in young healthy adults. Little is known of the daytime blue light influence on alertness in elders. A prospective with-in subject study was carried out in Peking University Third Hospital to evaluate the impact of cataract surgery on visual functions and the electroencephalogram alertness response to blue light stimulus before and after surgery. 14 participants diagnosed with age-related cataract were scheduled for monocular cataract surgery with ultraviolet-filtering intraocular lens (IOL) implantation...

Deep brain stimulation (DBS) is an effective treatment for movement disorders. It relies on the accurate placement of leads within small nuclei in the basal ganglia. Traditionally, this has been done with great success using frame-based stereotaxy. More recently, frameless systems have been introduced, and several studies have investigated whether they can achieve a similar accuracy. The objective of this meta-analysis was to assess the difference in targeting accuracy between frameless and frame-based systems in deep brain stimulation, using prior studies reporting error in all cardinal directions...

This study, an extension of Fernandes et al. (2017), provided consistent contrast sensitivity function (CSF) measurements in a large sample. CSF was assessed for luminance stimuli in different 48 chronic smokers and 50 healthy nonsmokers. Stimuli for the CSF were Gabor patches with spatial frequencies of .2, 2.5, 5.0, 10.0, and 20.0 cycles per degree (cpd). The use of Gabor patches minimizes uncertainty in spatial position and detection of frequencies. The Gabor patches consisted of vertical gratings that were multiplied by a two-dimensional spatial Gaussian envelope...

Muscular spasticity due to neurological disorders is a heavy cause of severe pain and disability for many patients, compromising the independence and quality life. Baclofene is a good tool to guarantee patients independence and pain control. Anyway in chronic therapy oral treatment become unsatisfactory. In all these cases, intrathecal baclofen therapy (ITB), after sub fascial implantation of intrathecal pumps is used as an important long term treatment to reduce spasticity. After pump implantation the drug reservoir must be refilled periodically in order to maintain the reduction of spasticity and avoid the symptoms and signs of withdrawal...

BACKGROUND: Transcranial direct current stimulation (tDCS) has been explored as a potential intervention in Parkinson's disease (PD) and recent studies have shown promising results in cognitive, gait and motor function. However, evidence of efficacy is limited due to small size studies, short treatment periods, lack of standardization of methodologies and other study design limitations. Remotely supervised-tDCS (RS-tDCS) allows "at-home" study participation, potentially easing recruitment, compliance and overall feasibility for clinical studies...

Posterior surgery has been widely used as an initial surgery for cervical ossification of the posterior longitudinal ligament (OPLL). However, some patients require revision surgery because of failure of symptom relief or late neurological deterioration after posterior surgery. The aim of this study is to retrospectively investigated the surgical results and complications of anterior controllable antedisplacement fusion (ACAF) as a revision surgical technique after initial posterior surgery for OPLL. The present study concluded 13 patients...

This nationwide study of the adult Korean population aimed to compare the survival period between synchronous and metachronous group and to determine recent treatment trends in newly diagnosed spine metastasis patients. Data were extracted from the Korean Health Insurance Review and Assessment Service database. Patients in this study were newly diagnosed with metastatic spine tumors between July 1, 2011 and June 31, 2014. The metachronous group was defined when the primary tumor was diagnosed prior to the diagnosis of spine metastasis, otherwise patients were considered to be the part of the synchronous group...

This report details prominent neuropsychiatric features in one family with an ADCY5 gene mutation. ADCY5 mutations cause a variable motor phenotype, though most cases have some core involuntary movement features. The psychiatric aspects of the disorder have not been emphasised in previous publications. We discuss possible pathogenesis.

Little is known about changes in glucose metabolism in patients with chronic severe traumatic brain injury (sTBI). It remains to be elucidated how neurological manifestations of sTBI are associated with brain glucose metabolism during longitudinal follow-up. We show here that neurological manifestations are associated with changes of brain glucose metabolism by using two serial 18F-fluorodeoxyglucose positron emission tomography/computed tomography (18F-FDG PET/CT) images. In this longitudinal observational study, two serial 18F-FDG PET/CT images from each of 45 patients were analyzed for whole-brain maximum standardized uptake values (SUVmax)...

Clinical decision making is susceptible to biases and can be improved with the application of predictive models and decision support systems (DSS). The purpose of this study was to develop a predictive risk stratification model and DSS that could accurately predict whether a patient was likely to be of high- or low-acuity discharge disposition (DD) status subsequent to DBS surgery. Data were collected for 135 DBS patients by reviewing medical records. Multivariate logistic regression was applied to develop the predictive algorithm...

Venous sinus thrombosis secondary to traumatic brain injury and head trauma is increasingly detected following contrast enhanced cranial imaging in acute trauma. The presence of sinus thrombosis poses further challenges in the management of traumatic brain injury patients with cerebral contusions, intraparenchymal haemorrhages or subdural/extradural haemorrhages. The decision to anti-coagulate such trauma induced venous sinus thrombosis is controversial and requires further attention and research to delineate risks versus benefits of treatment...

In this study the three-dimensional anatomy of the corona radiata and tapetum via the fiber dissection and diffusion tensor imaging of the brain for ventricular surgery was demonstrated. Ten formalin-fixed cerebral hemispheres were dissected for corona radiata and tapetum via Klingler's fiber dissection method under an operating microscope. The corona radiata and tapetum were dissected through lateral and medial surfaces of the cerebral hemisphere, respectively. All surgical routes for ventricular lesions were evaluated for white matter fibers during and after dissections...

Narrow cervical spinal canal is an important risk factor for the development of cervical myelopathy. Patients with this disease often present with congenital narrowness of the cervical spinal canal. While there are studies on patients with subaxial spinal canal stenosis (SAS), few examined the coexistence of congenital narrow spinal canal in patients with cervical myelopathy at the C1 level. We investigated the characteristics of patients with C1 stenosis (C1S) with special reference to the size of the atlas...

Posterior lumbar interbody fusion with cortical bone trajectory (CBT-PLIF) is a form of minimally invasive decompression and fusion, whereas microendoscopic laminotomy (MEL) is a form of minimally invasive decompression surgery. No study has compared the clinical outcomes of the two methods for patients who have degenerative spondylolisthesis (DS) with instability. In this study, CBT-PLIF and MEL were both offered to 64 patients who met the inclusion criteria. Each patient then selected his or her preferred treatment...

INTRODUCTION: Pulmonary emboli (PE) is a significant source of morbidity and mortality in the trauma patients. The use of chemical prophylaxis to prevent deep venous thrombosis and subsequent PE is still controversial given its risk of increased intracranial hemorrhage expansion. OBJECTIVE: In the present study, we evaluated the incidence of PE in severe traumatic brain injury. METHODS: Retrospective review of patients who were admitted to a Neurosurgery unit from 2011 to 2013 with severe TBI who developed PE...

Sterile postoperative seromas can develop after posterior spinal surgery and cause pain, weakness, and numbness. Management typically involves operative evacuation. We propose that these collections can be managed with percutaneous computed tomography (CT) guided aspiration, potentially saving the patient an additional surgery. Here, we evaluate the safety and efficacy of this approach. Patients who developed symptomatic postoperative seromas within 60 days following surgery for spinal canal stenosis and had stable neurologic exams were considered for CT-guided percutaneous aspiration...

Mahlon D Johnson
The management of meningiomas, especially inoperable, previously irradiated recurrent and anaplastic meningiomas has been challenging due to the paucity of effective chemotherapy. Numerous studies suggest that tumor-mediated immunosuppression may facilitate progression of many malignancies. Recent identification of PD-L1 expression in some types of cancer cells has raised the possibility that its inhibition of host immunosurveillance may be part of the mechanism. Thus, tumor cell PD-L1 might be a useful new target for chemotherapy in PD-L1- bearing tumors...

Synovial cysts constitute an uncommon degenerative lesion of the spine. They are usually asymptomatic but they may also cause symptoms of variable severity. The authors present three cases of such cysts, two in the lumbar region of a 55-year-old female and a 66 year old female and one in the cervical region of a 56-year-old male patient. All patients presented with radiculopathy. Magnetic Resonance Images revealed a cystic lesion at the L4/5 level in the first case, at L5/S1 level in the second case and at the C7/T1 junction level in the third case...
