Gita Khalili Moghaddam, Christopher Robin Lowe
The research reported herein integrates a generic holographic sensor platform and a smartphone-based colour quantification algorithm in order to standardise and improve the determination of the concentration of analytes of interest. The utility of this approach has been exemplified by analysing the replay colour of the captured image of a holographic pH sensor in near real-time. Personalised image encryption followed by a wavelet-based image compression method were applied to secure the image transfer across a bandwidth-limited network to the cloud...

BACKGROUND: Posterior fossa decompression without (PFD) or with duraplasty (PFDD) for the treatment of type 1 Chiari malformation (CM-I) is controversial. We thus did a systematic review and meta-analysis of studies to assess the effect on clinical and imaging improvement, operative time, complications and recurrence rate between PFD and PFDD in patients with CM-I. METHODS: We systematically searched PubMed, Embase, Cochrane, Web of Knowledge, and ClinicalTrials...

OBJECTIVE: The etiologies and epidemiology of traumatic cervical spine fracture have not been described with sufficient power or recency. Our goal is to describe demographics, incidence, etiology, spinal cord injuries (SCIs), concurrent injuries, treatments, and complications of traumatic cervical spine fractures. METHODS: Retrospective review of the Nationwide Inpatient Sample. ICD-9 E-Codes identified trauma cases from 2005-2013. Patients with cervical fracture were isolated...

Symptomatic spinal epidural hematoma (SSEH) following spinal surgery is rare but one of the serious complications. SSEH can leave devastating neurological consequences if missing the optimal timing for treatment. The early diagnosis of SSEH is critical to the neurologic recovery, and MRI examination can help to check the location and the scope of the hematoma and provide imaging information for surgical operation. The risk factors of SSEH can be divided into preoperative factors, intraoperative factors and postoperative factors...

Vertebral pathological fracture and metastatic epidural spinal cord compression (MESCC) due to metastatic cancer inevitably cause pain, neurological deficit, impaired function, and decreased quality of life and are indications for surgery. In such cases, earlier surgical intervention has the potential to prevent permanent neurological deficit and disability and to maintain function and quality of life. Therefore, the aim of this study was to identify and evaluate risk factors for pathological fracture and MESCC in patients with spinal metastases...

Retrograde false-lumen flow after thoracic endovascular aortic repair of Type B aortic dissection occurs occasionally and may have a negative impact on aortic remodelling and even prevent the decompression of the false lumen. A 67-year-old man with a Type B aortic dissection underwent thoracic endovascular aortic repair for severe compression of the true lumen and visceral malperfusion 7 weeks after the onset. Intraoperative angiography revealed proximal entry tear closure, but the false-lumen flow increased because of retrograde flow through the re-entry tear...

Fundamental computer science concepts have inspired novel information-processing molecular systems in test tubes (1-13) and genetically encoded circuits in live cells (14-21) . Recent research has shown that digital information storage in DNA, implemented using deep sequencing and conventional software, can approach the maximum Shannon information capacity (22) of two bits per nucleotide (23) . In nature, DNA is used to store genetic programs, but the information content of the encoding rarely approaches this maximum (24) ...

Foraminal stenosis causing nerve root compression and radiculopathy is a relatively common pathology in the lumbar spine. The treatment of choice, when surgery is indicated, is foraminal decompression at the affected level, usually through a conventional midline open foraminotomy. Minimally invasive lateral foraminotomy with partial lateral facetectomy is a potentially effective surgical alternative when such a surgery is warranted. The evaluation of the efficacy and benefits of this approach for treatment of radiculopathy; an assessment of facet integrity; and, a detailed description of the procedure are also provided...

OBJECTIVE: Among newer neuroprotectant modalities, hypothermia and progesterone have shown a beneficial role in preliminary studies enrolling patients with severe traumatic brain injury (sTBI). The primary objective of this study was to evaluate the efficacy of progesterone with or without prophylactic hypothermia in acute sTBI patients. MATERIALS AND METHODS: This is a prospective, outcome assessor, statistician blinded, randomized, and placebo-controlled phase II trial of progesterone with or without hypothermia (factorial design)...

INTRODUCTION: Patients with symptomatic spondylolisthesis are frequently treated with nerve root decompression, in addition to pedicle screw fixation and interbody fusion. Minimally invasive approaches are gaining attention in recent years, although there is no clear evidence supporting the proclamation of minimally invasive spine surgery (MISS) being better than open surgery. We present the design of the MISOS (Minimal Invasive Surgery versus Open Surgery) trial on the effectiveness of MISS versus open surgery in patients with degenerative or spondylolytic spondylolisthesis...

Victor E Staartjes, Marc L Schröder
BACKGROUND: The addition of fusion to decompression for stenosis with Grade I degenerative spondylolisthesis is a controversial topic, and the question remains if fusion provides any real benefit to the patient that warrants the increased healthcare utilization and perioperative morbidity. In addition, there is no consensus on indications for the use of fusion over decompression alone. METHODS: Patients received fusion or decompression according to a decision-making protocol based on their pattern of complaints, the location of the compression, as well as facet angles and effusion as proven predictors of postoperative instability...

The prevalence of gallstones is 10% to 15% in adults. Individuals with acute cholecystitis present with right upper quadrant pain, fever, and leukocytosis. Management includes supportive care and cholecystectomy. The prevalence of choledocholithiasis is 10% to 20%, and serious complications include cholangitis and gallstone pancreatitis. The goal of management in individuals with choledocholithiasis consists of clearing common bile duct stones. Acute ascending cholangitis is a life-threatening condition involving acute inflammation and infection of the common bile duct...

OBJECTIVE: The aim of this study was to analyze the depolymerization in metalloproteinase (ADAM17), epidermal growth factor receptor (EGFR), the expression of Ki-67 of glioma patients and the correlations with malignancy. PATIENTS AND METHODS: 53 brain glioma samples resected from patients who had surgery from April 2015 to May 2016 at Chinese People's Armed Police Force General Hospital were selected. According to the degree of malignancy: 22 patients were divided into a deterioration group (stage I to II); 31 patients in highly deteriorated group (stage III to IV); 14 brain tissue samples of traumatic decompression from the hospital as control group...

AIM: We assessed the role of triangular vertebral canal shape (VCS) in pain severity, pain-related findings, and postoperative satisfaction in patients with lumbar spinal stenosis (LSS) who had undergone decompressive surgery. MATERIAL AND METHODS: This cross-sectional study conducted at a single center included 61 consecutive patients who had undergone surgical treatment for LSS. By comparing pre- and postoperative data, the role of triangular VCS in pain severity [assessed using a visual analog scale (VAS)], pain-related findings, and postoperative satisfaction of patients was examined...
