How and when Trust in Authorities Contributes to Conformity toward COVID-19 Protective Actions.
Cutaneous melanoma metastases can contribute to visual disturbances through a variety of factors, including metastasis to the vitreal fluid. The optimum management of metastatic cutaneous melanoma to the vitreal fluid is unknown, but can include radiation therapy or systemic therapy including immunotherapy. A high degree of suspicion is necessary to consider this complication while working with patients with cutaneous melanoma.The results of local-regional advanced melanoma (stage III) management are still not satisfactory. Particularly, there is no personalized treatment in stage III melanoma patients due to the lack of useful classical pathological markers for prognostication of indolent or aggressive course of the disease. The aim of this study was to explore melanoma genomic landscape by means of the mutational profiling of 50 genes influencing carcinogenesis pathways in the randomly selected 93 kinase inhibitor-naïve (KI-naïve) stage III patients. The genomic alterations were found in 27 out of 50 tested genes and at least one pathogenic variant was detected in 77 out of 93 cases (82.7%). Survival rate was negatively affected by the presence of the somatic mutations in AKT1, ATM, CDH1 and SMARCB1, while the BRAF+ status in KI-naïve stage III population correlated with the longer median overall survival. Genomic alterations in WNT pathway correlated with extranodal adipocyte tissue involvement (P = 0.027) and higher number of metastatic lymph nodes (P = 0.045). In terms of survival, the Cox model confirmed the worse prognosis in patients with mutation in the WNT pathway [hazard ratio (HR) = 2.9, P = 0.017], and better prognosis in cases with mutations in BRAF pathway (HR = 0.5, P = 0.004). WNT/β-catenin pathway alteration was associated with more advanced/aggressive disease. From this perspective, the concept of blocking the activity of the WNT pathway in selected cases appears promising and complementary to the BRAF inhibition therapeutic option for the future.The treatment of cancer during pregnancy presents a unique challenge. Optimal treatments are often altered or even delayed to protect fetal growth and organogenesis. The landscape of cancer treatment has shifted dramatically over the past several years and treatment with checkpoint inhibitors, including anti-PD1 and anti-CTLA-4 agents has revolutionized treatment outcomes for patients across numerous tumor types. Until recently, little is known about the use of checkpoint inhibitor therapy during pregnancy; however, in animal studies, exposure to checkpoint inhibitors at the time of or after conception led to high incidences of spontaneous abortion, stillbirth, and premature delivery. In this report, we describe the successful pregnancy and clinical course of a patient diagnosed with metastatic melanoma who conceived twins while undergoing dual checkpoint blockade with ipilumumab and nivolumab. While there are case reports of patients receiving checkpoint inhibitors during pregnancy, our case is the first to describe a successful pregnancy that was conceived during treatment with combination anti-CTLA-4 and PD-1, with therapy continuing throughout pregnancy. This case adds to the growing evidence that favorable pregnancy outcomes may be possible while receiving checkpoint inhibition, which will hopefully allow for more optimal treatment of young pregnant patients with cancer.PURPOSE OF REVIEW The aim of this review is to provide insight into the diagnosis and management of patients with refractory coeliac disease (RCD) and highlight recent advances in this field. RECENT FINDINGS The diagnosis of RCD can be more accurately confirmed with flow cytometry in addition to immunohistochemistry. Dietary input and excretion of gluten immunogenic peptides can help rule out gluten contamination, and therefore, substantiate a diagnosis of RCD type I. Small bowel capsule endoscopy (SBCE) is important at diagnosis and follow-up in addition to duodenal histology. Apart from ruling out complications, it can give information on extent of disease in the small bowel, and therefore, help assess response to therapy. Those patients with a poor response can have earlier intensification of therapy, which may result in an improved outcome. RCD also occurs in patients with serology negative coeliac disease but with an increased mortality compared with patients with serology-positive coeliac disease. SUMMARY Patients with RCD can present with persistent symptoms of malnutrition but can also be completely asymptomatic. Serology is not a reliable marker to detect refractory disease. Immunostaining and flow cytometry are necessary for a diagnosis of RCD. Small bowel endoscopy enables disease extent to be assessed and allows for small bowel biopsies to be taken in case of suspicious lesions. Small bowel radiology can be complementary to small bowel endoscopy.PURPOSE OF REVIEW The present review offers its readers a practical overview of protein-losing enteropathy, particularly with regard to diagnostic and therapeutic approaches. The aim is to support clinicians in their daily practice with a practical tool to deal with protein-losing enteropathy. RECENT FINDINGS The literature covering protein-losing enteropathy does not appear to be quite recent and also guidelines are scanty. The main innovations during the last decade probably regard the introduction of enteroscopic techniques in the diagnostic flowchart. Mepazine supplier The use of video-capsule and device-assisted enteroscopy has enabled the direct exploration of the small bowel and the identification of the damage causing the loss of proteins from the gastrointestinal tract. Other innovations are to do with the therapies of the disorder underlying protein-losing enteropathy, although the support with nutritional supplementation are the direct remedies to tackle the protein loss. SUMMARY Protein-losing enteropathy represents an important clinical aspect of different gastrointestinal and extra-intestinal diseases. An established flowchart is still unavailable, but the use of enteroscopy has deeply changed the modern diagnostic approach. Nutritional support and therapy of the underlying disease are pivotal to patients' management.
