Minimally Invasive Resection of a Cervical Anterolateral Meningioma: 2-Dimensional Operative Video

Intradural extramedullary spinal tumors were historically managed through traditional midline approaches. Although conventional laminectomy or laminoplasty provides a wide tumor and spinal cord exposure, they may cause prolonged postoperative neck pain and late kyphosis deformity. Minimally invasive ipsilateral hemilaminectomy preserves midline structures, reduces the paraspinal...

Resection of a Pediatric Intramedullary Spinal Cord Tumor: 2-Dimensional Operative Video

This video is a case presentation and demonstration of surgical approach to a pediatric intramedullary spinal cord tumor (IMSCT). IMSCT can be associated with significant morbidity and aggressive resection is associated with more favorable long-term outcome. A 13-yr-old male presented to clinic for evaluation of rapidly progressive scoliosis to the left. A contrasted MRI revealed...

High Cervical Ependymoma Resection: 2-Dimensional Operative Video

This operative video illustrates resection of a cervical ependymoma in a 40-yr-old female with numbness of upper and lower extremities and ataxia. Magnetic resonance imaging (MRI) demonstrated an enhancing intramedullary intradural spinal mass at C2-3. The patient underwent a posterior cervical laminoplasty for tumor resection. This video highlights the natural history of this...

Working Channel Endoscopic Interlaminar Microdiscectomy: 2-Dimensional Operative Video

This video demonstrates a working channel interlaminar microdiscectomy performed in a patient with significant back and leg pain due to a persistent disc herniation. We describe this technique in detail, describing the endoscopic anatomy and illustrating key steps to safely perform this operation. Due to the limited soft tissue destruction required to access the disc space with...

Summary of the safety and tolerability of two treatment regimens of ceftaroline fosamil: 600 mg every 8 h versus 600 mg every 12 h

The recommended adult dose of ceftaroline fosamil is 600 mg q12h by 1 h intravenous (iv) infusion for 5–14 days in complicated skin and soft tissue infection (cSSTI) and 5–7 days in community-acquired pneumonia (CAP). A dosage of 600 mg q8h by 2 h iv infusion is approved in some regions for cSSTI patients with Staphylococcus aureus infection where the ceftaroline MIC is 2 or 4 mg...

Reliance on Facebook for news and its influence on political engagement

This paper examines the link between reliance on Facebook for news, political knowledge, and political engagement in the Philippines. We tested five hypotheses using data gathered from an online survey of 978 Filipinos conducted from February 1 to March 31, 2016. Findings support the hypothesis that those who rely less on social media as a news source exhibit higher levels of...

Quantifying pine processionary moth defoliation in a pine-oak mixed forest using unmanned aerial systems and multispectral imagery

Pine processionary moth (PPM) feeds on conifer foliage and periodically result in outbreaks leading to large scale defoliation, causing decreased tree growth, vitality and tree reproduction capacity. Multispectral high-resolution imagery acquired from a UAS platform was successfully used to assess pest tree damage at the tree level in a pine-oak mixed forest. We generated point...

Herd Immunity Likely Protected the Men Who Have Sex With Men in the Recent Hepatitis A Outbreak in San Diego, California

A high seroprevalence of hepatitis A virus (81%) among human immunodeficiency virus–negative high-risk men who have sex with men is likely why this community was largely spared from a recent hepatitis A virus outbreak in San Diego, California.

Validation of the French version of the LEIPAD in community-dwelling people aged 80 years and above

Background Few studies have addressed health-related quality of life in community-dwelling individuals aged 80 years and above and very few self-assessment quality of life questionnaires have been formally validated in these populations. This study aimed to validate a French version of the LEIPAD, a self-administered questionnaire assessing the health-related quality of life of...

Exploring the bacteriome in anthropophilic ticks: To investigate the vectors for diagnosis

Objective The aim of this study was to characterize the bacterial microbiome of hard ticks with affinity to bite humans in La Rioja (North of Spain). Methods A total of 88 adult ticks (22 Rhipicephalus sanguineus sensu lato, 27 Haemaphysalis punctata, 30 Dermacentor marginatus and 9 Ixodes ricinus) and 120 I. ricinus nymphs (CRETAV collection, La Rioja, Spain), representing the...

The effectiveness of colchicine combined with mitomycin C to prolong bleb function in trabeculectomy in rabbits

Purpose To investigate the potential of colchicine to improve bleb function after trabeculectomy. Methods To find the maximum usable colchicine concentration, an ocular irritation study was performed with the Draize test at concentrations of 0.001%, 0.01% and 0.1%. Additionally, the synergistic effect of topical colchicine instillation and MMC application to surgical site was...

Development of high-performance two-dimensional gel electrophoresis for human hair shaft proteome

The primary components of human hair shaft—keratin and keratin-associated proteins (KAPs), together with their cross-linked networks—are the underlying reason for its rigid structure. It is therefore requisite to overcome the obstacle of hair insolubility and establish a reliable protocol for the proteome analysis of this accessible specimen. The present study employed an...

Diagnosing cardiovascular disease in western lowland gorillas (Gorilla gorilla gorilla) with brain natriuretic peptide

Cardiovascular disease is a leading cause of death in zoo-housed great apes, accounting for 41% of adult gorilla death in North American zoological institutions. Obtaining a timely and accurate diagnosis of cardiovascular disease in gorillas is challenging, relying on echocardiography which generally requires anesthetic medications that may confound findings and can cause severe...
