Radiation oncologists are increasingly tasked with the management of elderly patients with non-melanoma skin cancer, unsuitable for surgical intervention due to inoperable lesions and/or poor performance status. In this cohort, hypofractionated radiotherapy, delivered either daily, alternative daily or once weekly is highly effective. A systematic literature search was conducted of PUBMED, MEDLINE and EMBASE databases using the algorithm ('radiotherapy' OR 'radiation therapy' OR 'brachytherapy') AND ('hypofraction' OR 'hypofractionated' OR 'hypofractionation') AND ('skin neoplasms' OR 'carcinoma' OR 'malignancy') AND ('skin' OR 'epidermis' OR 'epidermal' OR 'cutaneous')...

An unknown mass in the left atrium can be challenging to differentiate, especially after previous heart transplant. A precise diagnosis is clinically crucial because of the therapeutic implications. CMR is a useful, non-invasive tool to distinguish intra-cardiac lesions, thereby enabling clinicians to initiate adequate therapy.

Juvenile allogenic chondrocyte implantation (JACI; DeNovo NT Natural Tissue Graft®; Zimmer, Warsaw, IN) with autologous bone marrow aspirate concentrate (BMAC) is a relatively new all-arthroscopic procedure for treating critical-size osteochondral lesions (OCLs) of the talus. Few studies have investigated the clinical and radiographic outcomes of this procedure. We collected the clinical and radiographic outcomes of patients who had undergone JACI-BMAC for talar OCLs to assess treatment efficacy and cartilage repair tissue quality using magnetic resonance imaging (MRI)...

AIMS: HIF is an important transcription-regulator for adaptation to cellular stress in cells of myeloid origin. Classically, expression and activity of HIF1-α is regulated by oxygen-concentration within cell. However, there exists an alternative regulatory mechanism affecting HIF1-α levels independent of oxygen concentration particularly in inflammatory cells like macrophages. Here we report the mechanism of HIF1-α upregulation in TAMs by Oncostatin-M (OSM) independent of cellular oxygen concentration...

BACKGROUND: FDA approved the Gore Viabahn (WL Gore, Flagstaff, AZ, USA) stent for both femoro-popliteal arterial denovo and instent restenosis (ISRS) lesions. To date there is little data on Viabahn stent graft outcomes in ISRS arterial disease. METHODS: Between 2007 and 2014 we identified 734 patients who underwent 1573 endovascular interventions in our institution for infra-inguinal revascularization. Among these, 48 patients had 143 Viabahn stents placed. Of these, 26 patients had 94 stents placed for ISRS and 22 patients had 49 stents placed for denovo lesions...

Salivary Duct Carcinoma (SDC) is a distinctive and clinically aggressive adenocarcinoma of salivary origin. It arises from the ductal epithelium, predominantly occurring in the major salivary glands, especially the parotid gland. Here, we report a case of an extensive salivary gland pathology involving the right side of face, possibly arising from the parotid gland in a 25-year-old male patient. On routine histopathology, the tumour mass revealed a papillary pattern of neoplastic ductal epithelial cells showing comedo-like-central necrosis...

BACKGROUND: Articular cartilage injuries are a common injury among young, active patients, and the most appropriate treatment for these injuries remains controversial. A promising new technology in the treatment of high-grade cartilage injuries is particulated juvenile articular cartilage (PJAC) allograft (DeNovo NT, Zimmer, Warsaw, Indiana). This has been shown to be successful in multiple joints including the knee, talus, and elbow. No studies or case reports exist in supporting or discouraging its use in injuries of the wrist, in specific, the scaphoid...

BACKGROUND: Gastrodia elata is a well-known medicinal orchid. In nature, the germination rate of G. elata is extremely poor, because there is no endosperm within the mature seed. It is crucial for G. elata to obtain nutrition from mycorrhizal fungi (Mycena) at the early-stage of germination. After germination, the seed gives rise to a protocorm. However, there are no "omic" studies on understanding the interaction between Gastrodia and Mycena. Here, we used transcriptomic approaches to explore changes in seed germination of G...

BACKGROUND: Response to Hepatitis B virus (HBV) vaccination can be diminished in some (50-80%) but not all dialysis patients. We hypothesized, that the response to vaccination on dialysis may correlate with the development of anti-HLA antibodies after renal transplantation and might therefore be a valuable parameter to predict alloresponses. METHODS: The response to HBV vaccination on dialysis and the development of deNovo anti-HLA antibodies post-transplant was analyzed in 188 non-immunized renal transplant recipients...

Ameloblastic Carcinoma (AC) is uncommon malignant epithelial odontogenic tumour of jaw, with characteristic histologic features and behavior. Clinically, it has aggressive, infiltrative growth pattern with a distinct predilection for mandible. It exhibits histologic features of ameloblastoma and gets dedifferentiated overtime to culminate in carcinoma. Majority of the cases arise denovo (primary) and only few cases arise from a pre-existing ameloblastoma (secondary). Spindle-cell differentiation in ameloblastic carcinoma is rare; Salter described it as a separate entity "low-grade spindle cell ameloblastic carcinoma...

Single nucleotide polymorphisms (SNPs) in choline metabolizing genes are associated with disease risk and greater susceptibility to organ dysfunction under conditions of dietary choline restriction. However, the underlying metabolic signatures of these variants are not well characterized and it is unknown whether genotypic differences persist at recommended choline intakes. Thus, we sought to determine if common genetic risk factors alter choline dynamics in pregnant, lactating, and non-pregnant women consuming choline intakes meeting and exceeding current recommendations...

INTRODUCTION: Motor cortex plasticity is reported to be decreased in Parkinson's disease in studies which pooled patients in various stages of the disease. Whether the early decrease in plasticity is related to the motor signs or is linked to the future development of motor complications of treatment is unclear. The aim of the study was to test if motor cortex plasticity and its cerebellar modulation are impaired in treatment-naïve Parkinson's disease, are related to the motor signs of the disease and predict occurrence of motor complications of treatment...

Whole-exome and whole-genome sequencing have facilitated the large-scale discovery of de novo variants in human disease. To date, most de novo discovery through next-generation sequencing focused on congenital heart disease and neurodevelopmental disorders (NDDs). Currently, de novo variants are one of the most significant risk factors for NDDs with a substantial overlap of genes involved in more than one NDD. To facilitate better usage of published data, provide standardization of annotation, and improve accessibility, we created denovo-db (http://denovo-db...

Background: Sperm DNA damage is underlying aetiology of poor implantation and pregnancy rates but also affects health of offspring and may also result in denovo mutations in germ line and post fertilization. This may result in complex diseases, polygenic disorders and childhood cancers. Childhood cancer like retinoblastoma (RB) is more prevalent in developing countries and the incidence of RB has increased more than three fold in India in the last decade. Recent studies have documented increased incidence of cancers in children born to fathers who consume alcohol in excess and tobacco or who were conceived by assisted conception...

BACKGROUND: The technique of axillary vein (AV) or subclavian vein (SV) puncture has become an important alternative to cephalic vein (CV) cutdown as an approach allowing cardiac lead introduction into the venous system during cardiac implantable electronic device (CIED) implantation procedures. Irrespective of the technique used, the injury associated with lead insertion may induce a reflex venous spasm that can even cause total venous obstruction. In order to assess the incidence of AV spasm during AV puncture, we analysed a total of 735 (382 in females and 353 in males; mean age 75 ± 11 years) de novo CIED implantation procedures involving transvenous lead insertion conducted between January 2014 and December 2015...
