BACKGROUND: Mutations in GNAQ/11 genes are considered an early event in the development of uveal melanoma that may derive from a pre-existing nevus. The Hippo pathway, by way of YAP activation, rather than MAP kinase, has a role in the oncogenic capacity of GNAQ/11 mutations. METHODS: We investigated 16 nevi from 13 human eyes for driver GNAQ/11 mutations using droplet digital PCR and determined whether nevi are clonal by quantifying mutant nevus cell fractions...

Familial risks of breast cancer (BC) are well established but whether BC clusters with other, i.e. discordant, cancers is less certain but of interest for the identification of common genetic and possible environmental factors contributing to a general cancer susceptibility. We apply a novel approach to search for familial associations of BC with other (discordant) cancers based on the Swedish Family-Cancer Database. Relative risks (RRs) were calculated for BC in families with increasing numbers of patients with discordant cancer X, and conversely, familial RRs for cancer X in families with increasing numbers of BC patients...

INTRODUCTION: Retinoblastoma represents only 3% of paediatric cancers, but it is the most prevalent intraocular tumour in this population. It develops in the retina as a primitive neuroectodermal tumour that affects development during gestation. The tumour presents in two different forms depending on whether or not it expresses a genetic modification. For patients diagnosed at preschool age, 75% are unilateral non-hereditary cases. While enucleation is the preferred treatment for advanced stages of the tumour, other modalities, such as systemic and intraocular chemotherapy, radiotherapy and local treatments with thermotherapy, cryotherapy, and brachytherapy can be used to try to preserve the eye...

A 73-year-old woman diagnosed with unresectable pancreatic cancer received weekly gemcitabine(GEM)plus albuminbound paclitaxel(nab-PTX)therapy. Four months after nab-PTX therapy was initiated, she presented with a rapidly decreasing vision in her left eye at an ophthalmology clinic. On admission, her visual acuity was decreased, and optical coherence tomography(OCT)revealed a cystoid macular edema(CME)only in her left eye. She discontinued the nab-PTX therapy immediately. Her visual acuity improved on follow-up 6 months later...

OBJECTIVE: Skin cancer is to a large degree behaviourally preventable, meaning that evidence-based interventions have scope to make a difference. Previous research indicates that appearance-based interventions such as facial morphing may be more effective than health-based interventions, and that it can personalise the issue of skin cancer. METHOD: This study examined attitudes to UV exposure, as well as reactions to a facial morphing intervention, through interviews with 25 women aged 35 years and older...

In the modern clinical practice of diagnostic radiology there is a growing demand for radiation dosimetry, it also being recognized that with increasing use of X-ray examinations additional population dose will result, accompanied by an additional albeit low potential for genetic consequences. At the doses typical of diagnostic radiology there is also a low statistical risk for cancer induction; in adhering to best practice, to be also implied is a low but non-negligible potential for deterministic sensitive organ responses, including in regard to the skin and eyes...

The visual detection of a disease biomarker is a promising strategy due to its simplicity and low cost, but the complexity of biological samples limits its application. Herein, a reliable and ultrasensitive colorimetric assay was proposed for detecting telomerase activity in crude cancer cell extracts. A telomerase substrate (TS) primer was immobilized onto magnetic beads (MBs) to form a MB/TS complex. In the presence of telomerase and deoxyribonucleotide triphosphates (dNTPs), the TS primer was elongated by adding multiple telomeric repeats (TTAGGG)n to the 3' end of the TS...

An 83-year-old man, a prostate cancer survivor of 10 years with multiple vertebral metastases presented with sudden onset of double vision. On examination he was found to have an isolated partial left abducens palsy with no other neurological deficits. Despite having microvascular risk factors, given his history of prostate cancer, aMRI brain scan was requested to look for a neurological cause. The scan revealed a metastatic lesion in the clivus encasing the cavernous sinus and carotid artery. He was referred to his oncologist for further management, however he opted out of further treatment and succumbed to his illness a month later...

Skin self-examination (SSE) consists of routinely checking the body for atypical moles that might be cancerous. Identifying atypical moles is a visual task; thus, SSE training materials utilize pattern-focused visuals to cultivate this skill. Despite widespread use, researchers have yet to explicate how pattern-focused visuals cultivate visual skill. Using eye tracking to capture the visual scanpaths of a sample of laypersons (N = 92), the current study employed a 2 (pattern: ABCDE vs. ugly duckling sign [UDS]) × 2 (presentation: photorealistic images vs...

BACKGROUND: There is inconclusive evidence from observational studies to suggest that people who eat a diet rich in antioxidant vitamins (carotenoids, vitamins C, and E) or minerals (selenium and zinc) may be less likely to develop age-related macular degeneration (AMD). OBJECTIVES: To determine whether or not taking antioxidant vitamin or mineral supplements, or both, prevent the development of AMD. SEARCH METHODS: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (which contains the Cochrane Eyes and Vision Trials Register) (2017, Issue 2), MEDLINE Ovid (1946 to 29 March 2017), Embase Ovid (1947 to 29 March 2017), AMED (Allied and Complementary Medicine Database) (1985 to 29 March 2017), OpenGrey (System for Information on Grey Literature in Europe) (www...

Ever since initial suggestions that instability at common fragile sites (CFSs) could be responsible for chromosome rearrangements in cancers, CFSs and associated genes have been the subject of numerous studies, leading to questions and controversies about their role and importance in cancer. It is now clear that CFSs are not frequently involved in translocations or other cancer-associated recurrent gross chromosome rearrangements. However, recent studies have provided new insights into the mechanisms of CFS instability, their effect on genome instability, and their role in generating focal copy number alterations that affect the genomic landscape of many cancers...

PURPOSE: Hyperthermia and radiation have the ability to induce structural and morphological changes on both macroscopic and microscopic level. Normal and damage cells have a different texture but may be perceived by human eye, as having the same texture. MATERIALS AND METHODS: To explore the potential of texture analysis based on run-length matrix, a total of 32 sphere images for each group and treatment regime were used in this study. Cells were subjected to the treatment with different doses of 6 MeV electron radiation (0 2, 4 and 6 Gy), hyperthermia (at 43° C in 0, 30, 60 and 90 min) and radiation + hyperthermia (at 43°C in 30 min with 2, 4 and 6 Gy dose) respectively...

PURPOSE: Little is known about black African (BA) and black African-Caribbean (BAC) men's views towards cancer; yet culture and acculturation can contribute to the way in which people understand, explain and develop their attitudes towards cancer. Hence, cancer prevention and early detection strategies may not be sensitive to United Kingdom (UK)-based black men's views, affecting their awareness of risk factors and early detection services. This study explored the views of UK-based BA and BAC men towards cancer...

REVIEW
Cynthia D Cooper
Black pigment cells, melanocytes, arise early during development from multipotent neural crest cells. Melanocytes protect human skin from DNA damaging sunrays and provide color for hair, eyes and skin. Several disorders and diseases originate from these cells, including the deadliest skin cell cancer, melanoma. Thus, melanocytes are critical for a healthy life and for protecting humans from disease. Due to the ease of visualizing pigment cells through transparent larvae skin and conserved roles for zebrafish melanophore genes to mammalian melanocyte genes, zebrafish larvae offer a biologically relevant model for understanding pigment cell development and disease in humans...

Gonadotropin-releasing hormone agonists, used widely in the treatment of metastatic prostate cancer and hormone receptor-positive breast cancer, are associated with a rare but potentially fatal outcome of pituitary apoplexy (PA). An 85-year-old man presented with sudden onset of headache, left eye pain, sensitivity to light, nausea and vomiting. The symptoms started 4 hours after initiation of leuprolide therapy for treatment of recently diagnosed metastatic prostate carcinoma. Radiological imaging of the brain demonstrated a heterogeneously enlarged pituitary gland measuring 19×16×13 mm and T1-hyperintense signal compatible with pituitary haemorrhage...
