A Case of Switching from GnRH Agonist to Antagonist for Castration Resistant Prostate Cancer Control
GnRH antagonist and GnRH agonist are widely used as androgen deprivation therapy for metastatic prostate cancer. A previous report demonstrated that patients with PSA levels of #x3e;20 ng/mL using GnRH antagonists showed favorable outcomes in comparison to those using GnRH agonists. An 82-year old male patient with edema, a stony hard nodule on his prostate, and an initial PSA level of 6,717 ng/mL was referred to our hospital due to suspected prostate cancer. He received prostate needle biopsy and...
Neurothekeoma (NTK) is a specific benign soft tissue tumor, typically involving the skin of the head and neck area as well as the upper part of the body in young age with female predominance. It has a typical lobular pattern of growth but often displays atypical features such as myxoid stroma or fascicular pattern, which makes the diagnosis more difficult and may necessitate the use of immunohistochemical staining to differentiate NTK from nerve sheath tumor. Ocular NTK in general is very rare with...
Adenoid cystic carcinomas (ACCs) are malignant tumors that most often occur in the salivary glands and bronchi, with occurrence in the breast being rare. ACCs of the breast reportedly give rise to few lymph node metastases or distant metastases and have a favorable prognosis. A 56-year-old woman with a left breast mass identified by mammographic screening was examined at our institute. Breast ultrasound revealed a sharply marginated, hypoechoic mass 12.7 × 9.4 × 8.7 mm in size in the upper outer...
Epithelioid hemangioma is an uncommon benign vascular neoplasm which can arise in bone. Resection is generally curative, but occasionally lesions recur and recurrence after surgery can be morbid and destructive. Recent case reports have described the effective use of oral propranolol to control recurrent epithelioid hemangioma of the orbit. We report the case of a 26 year old man with recurrent aggressive osseous epithelioid hemangioma in the pelvis of which has been controlled for over a year with...
Prior to the advent of immune checkpoint inhibitors targeting PD-1/PD-L1 axis no drug demonstrated to improve survival or quality of life in the second-line treatment of recurrent or metastatic head and neck squamous cell carcinoma (R/M-HNSCC). Nivolumab appear to have a clear clinical benefit for R/M-HNSCC, based on improved survival, good toxicity profile, reduction in symptoms and improvement in overall quality of life. This benefit seems to be greater for PD-L1 positive patients and independent...

Superior vestibular neuritis: improved detection using FLAIR sequence with delayed enhancement (1 h)
Abstract Introduction Vestibular neuritis is the second cause of vertigo and new imaging protocols using delayed FLAIR with double-dose of gadolinium are proposed for its diagnosis. Our aim is to demonstrate that a single dose of gadolinium is sufficient. Methods Thirty-three patients with a unilateral vestibular neuritis are compared to a control group....
Abstract Purpose Surgical treatment is generally recommended for severe subglottic lesions following traumatic endotracheal intubation in children. An alternative approach is early transglottic corticosteroid administration to reduce scar formation and prevent the need for subsequent surgical intervention. This technique has been practiced successfully for several decades at the Children’s Hospital of Cologne and the outcomes of 26 subsequent...

Abstract Despite widespread evidence that mating and intra‐sexual competition are costly, relatively little is known about how these costs dynamically change male and female phenotypes. Here, we test multiple hypotheses addressing this question in replicate flocks of red junglefowl (Gallus gallus). First, we test the inter‐relationships between social status, comb size (a fleshy ornament) and body mass at the onset of a mating trial. While comb size covaried positively with body mass across individuals...
The adaptive value of epigenetic mutation: limited in large but high in small peripheral populations
Abstract The fate of populations during range expansions, invasions, and environmental changes is largely influenced by their ability to adapt to peripheral habitats. Recent models demonstrate that stable epigenetic modifications of gene expression that occur more frequently than genetic mutations can both help and hinder adaptation in panmictic populations. However, these models do not consider interactions between epimutations and evolutionary forces in peripheral populations. Here we use mainland‐island...
Abstract Evolutionary theory predicts that females seek extra‐pair fertilisations from high‐quality males. In socially monogamous bird species, it is often old males that are most successful in extra‐pair fertilisations. Adaptive models of female extra‐pair mate choice suggest that old males may produce offspring of higher genetic quality than young males because they have proven their survivability. However, old males are also more likely to show signs of reproductive senescence, such as reduced...

Abstract People can quickly detect bilateral reflection in an image. This is true when elements of the same luminance are matched on either side of the axis (symmetry) and when they have opposite luminance polarity (anti‐symmetry). Using EEG, we measured the well‐established Sustained Posterior Negativity (SPN) response to symmetry and anti‐symmetry. In one task, participants judged the presence or absence of regularity (Regularity Discrimination Task). In another, they judged the presence or absence...

Abstract The main effectors in tumor control are the class I MHC molecule-restricted CD8+ cytotoxic T lymphocytes (CTLs). Tumor-specific CTL induction can be regulated by dendritic cells (DCs) expressing both tumor-derived epitopes and co-stimulatory molecules. Immunosuppressive tolerogenic DCs, having down-regulated co-stimulatory molecules, are seen within the tumor mass and can suppress tumor-specific CTL induction. The tolerogenic DCs expressing down-regulated XCR1+CD141+ appear...

Many of today’s smaller surgical clinics have to sterilize equipment in-house, and autoclave sensitive instruments are processed using ethylene oxide, a carcinogenic, explosive, and irritating gas. Gas plasma is another low temperature option, but it requires large and expensive equipment that doesn’t make sense for small practices. A new company called Plasmapp has developed small gas plasma sterilizers that are fast, affordable, and can be placed in any size clinic. Moreover, they...
Siemens Healthineers won FDA clearance for the ARTIS icono angiography systems that are designed for use in a variety of procedure types. The ARTIS icono 2D/3D biplane system is intended for neuroradiology and abdominal imaging while the ARTIS icono floor has a single fluoroscope and is designed for vascular, interventional cardiology, surgical, and oncology procedures. Siemens touts its “OPTIQ image chain” implemented in the ARTIS icono, which supposedly “redesigns image processing for 2D...
Ventrix, a spin-off company of the University of California San Diego, has developed a special hydrogel that can be injected into the heart to provide a platform for cardiac repair following a heart attack. The technology was just tested in humans for the first time as part of an FDA-approved Phase 1 clinical trial. Though limited in size, the study pointed to the safety of the hydrogel and there are definite signs that it helps to improve cardiac function. The hydrogel is produced from the...
Biologics, being a group of drugs synthesized from biological sources, are often produced using bacteria. The manufacturing processes are usually slow and laborious, though they do benefit from economies of scale. Producing small quantities of biologics is typically limited to research labs, and even there it is limited in scope. Researchers at Duke University have now come up with an entirely new way to manufacture biologic drugs using engineered bacteria and tiny capsules. The bacteria,...
