93). A density plot for normalized expression of shared genes on both platforms showed comparable bi-modal distribution and dynamic range. RNASeq demonstrated relatively larger signaling intensity whereas nCounter system displayed higher inter- sample variability. Estimated fold changes for all shared genes showed high correlation (Spearman coefficient 0.73). This agreement is even better when only significantly differentially expressed genes were compared. Composite gene expression profiles, such as an interferon gamma (IFNg) signature, can be reliably inferred by both assays. In summary, our study demonstrates that focused transcript read-outs can reliably be achieved by both technologies, and shows that both approaches achieve comparable results despite their intrinsic technical differences.

OBJECTIVE To identify the cause of autosomal dominant tremulous myoclonus-dystonia in a UK kindred with affected individuals in three generations. METHODS Known genetic causes of myoclonus-dystonia were excluded. We combined clinical and electrophysiological phenotyping with whole-exome sequencing and Sanger sequencing to identify candidate causal variants in a family with tremulous myoclonus-dystonia. RESULTS The core phenotype consisted of childhood-onset dystonia predominantly affecting hands and neck, with a fast tremor with superimposed myoclonus, and in some, subtle cerebellar signs. We identified a novel missense variant in KCNN2 (NM_021614c.1112G>Ap.(Gly371Glu)) which was the only variant we were able to identify segregating with the phenotype over three generations. This variant, which is absent from the most recent version of gnomAD, was predicted to be deleterious by SIFT and PolyPhen-2, and obtained an overall CADD score of 29.7. CONCLUSION KCNN2 (potassium calcium-activated channel subfamily N member 2), a member of the KCNN family of potassium channel genes, is highly conserved across species and in humans is highly expressed in the brain, particularly the cerebellum. KCNN2 mutations have never been described as pathological in human disease, but are recognised abnormalities in two rodent models of fast, jerky tremor. Segregation, absence of the variant in the normal population and in silico prediction of a deleterious effect together with animal models compatible with the clinical phenotype are all in line with KCNN2 mutations being a plausible cause underlying myoclonus-dystonia.

Greater knowledge of the disease, which is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV2), will help us to prioritise our limited health resources. Because the virus is new, and no vaccine is yet available, everyone is naïve and susceptible to being infected with SARS-CoV2. The virus will continue to spread until an effective vaccine exists or sufficient members of our global population have been infected to establish herd immunity. At the moment, the best way to minimize loss of life and severe cases requiring intensive care is to try and shelter vulnerable groups of individuals and slow down the spread of the virus.

Examine differential staging of tumors across the three systems and the resulting implications for clinical decision making. STUDY DESIGN Retrospective chart review. METHODS This study included 118 patients who underwent excision of primary cSCC of the head and neck as well as elective neck dissection for the same tumor between 2006 and 2017. Tumors were staged using the 2010 7th edition American Joint Committee on Cancer (AJCC 7) staging system, the 2016 8th edition AJCC staging system (AJCC 8), and the Brigham and Women's Hospital (BWH) alternative tumor staging system published in 2013. RESULTS There were 28 patients (23.7%) with positive nodal metastases at the time of tumor excision. this website Almost all tumors staged as tumor (T)2 using AJCC 7 were upstaged to T3 or T4 using the new AJCC 8, and these two groups accounted for the majority of the nodal metastases. Similarly, the BWH-staged T3 group contained the highest number of tumors with nodal metastases. None of the three staging systems significantly stratified tumors in a manner that predicted the presence of nodal metastases. CONCLUSION Individuals with cSCC tumors staged T3 or higher in the AJCC 8 and BWH staging systems should undergo neck dissection, whereas those with lower staging should be discussed with the patient on a case-by-case basis.

STUDY DESIGN Prospective, blinded, controlled clinical trial. SAMPLE POPULATION Healthy dogs undergoing orthopedic surgery (n = 10). METHODS Half of the length of each surgical wound was treated with Phovia, and the remaining 50% was treated with saline solution on the first day after surgery and every 3 days until day 13. Wound healing of treated and control areas within each wound was evaluated via macroscopic assessment and histological and immunohistochemical analysis of treated and control wounds. RESULTS The areas treated with Phovia achieved lower histology scores (P = .001), consistent with complete re-epithelialization, less inflammation of the dermal layer, and greater and more regular deposition of collagen. According to immunohistochemistry, expression of factor VIII, epidural growth factor, decorin, collagen III, and Ki67 was increased in treated compared with untreated tissues.
