ER stress promotes antitumor effects in BRAFi/MEKi resistant human melanoma induced by natural compound 4-nerolidylcathecol (4-NC).

Pharmacol Res 2018 Dec 11. Epub 2018 Dec 11.

Skin Biology Group, Clinical Chemistry and Toxicology Department, School of Pharmaceutical Sciences, University of São Paulo, São Paulo, Brazil. Electronic address:

Melanoma accounts for only 4% of malignant neoplasms of the skin, but is considered the most serious because it is highly deadly. Mutations in the MAPK (Ras-Raf-MEK-ERK) pathway is closely linked to the lack of control of cell proliferation. Especially in melanoma, this pathway has become a target for the development of oncogene-targeted therapies, such as the potent inhibitors of v-Raf murine sarcoma viral oncogene homolog B (BRAFi) and mitogen-activated protein kinase kinase (MEKi).

Cancer Neoantigens.

Annu Rev Immunol 2018 Dec 14. Epub 2018 Dec 14.

Division of Molecular Oncology and Immunology, The Netherlands Cancer Institute, 1066 CX Amsterdam, The Netherlands; email: ,

Malignant transformation of cells depends on accumulation of DNA damage. Over the past years we have learned that the T cell-based immune system frequently responds to the neoantigens that arise as a consequence of this DNA damage. Furthermore, recognition of neoantigens appears an important driver of the clinical activity of both T cell checkpoint blockade and adoptive T cell therapy as cancer immunotherapies. Read More

What We Already Know About This Topic: WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Although dantrolene effectively treats malignant hyperthermia (MH), discrepant recommendations exist concerning dantrolene availability. Whereas Malignant Hyperthermia Association of the United States guidelines state dantrolene must be available within 10 min of the decision to treat MH wherever volatile anesthetics or succinylcholine are administered, a Society for Ambulatory Anesthesia protocol permits Class B ambulatory facilities to stock succinylcholine for airway rescue without dantrolene. The authors investigated (1) succinylcholine use rates, including for airway rescue, in anesthetizing/sedating locations; (2) whether succinylcholine without volatile anesthetics triggers MH warranting dantrolene; and (3) the relationship between dantrolene administration and MH morbidity/mortality.

In-Phase and Opposed-Phase Imaging: Applications of Chemical Shift and Magnetic Susceptibility in the Chest and Abdomen.

Radiographics 2018 Dec 14:180043. Epub 2018 Dec 14.

From the Mallinckrodt Institute of Radiology, Washington University School of Medicine, 510 S Kingshighway Blvd, Campus Box 8131, St Louis, MO 63110.

For the radiologist performing body MRI, chemical shift imaging is a unique tool available to investigate the cellular composition of tissue. By leveraging the inherent difference in resonant frequency between water and fat protons that is due to their local chemical environment, chemical shift image acquisition can be timed to image water and fat protons when their collective signals are in phase or out of phase, to determine the relative amount of fat signal and water signal within an individual voxel. Loss of signal intensity between the in-phase and opposed-phase MR images indicates intravoxel lipid and can be used to make definitive benign diagnoses, characterize the tissue composition of solid organs, and serve as an adjunct imaging feature aiding in the diagnosis of a variety of benign and malignant processes in the chest and abdomen.

Long-term use of low-molecular-weight heparin in a patient with Heartware BIVAD (HVAD) with underlying sustained ventricular fibrillation.

J Cardiol Cases 2016 Dec 7;14(6):171-173. Epub 2016 Sep 7.

Division of Cardiovascular Surgery, Mazankowski Alberta Heart Institute, Edmonton, Alberta, Canada.

We report the case of a 59-year-old patient with Heartware (Framingham, MA, USA) biventricular assist device (BIVAD) implantation who had long-term sustained ventricular fibrillation and was managed on low-molecular-weight heparin for up to two years without any adverse events. The successful outcome in this case provides a clue that the long-term management of Heartware BIVADs with low-molecular-weight heparins could be a viable option even in patients with underlying malignant arrhythmias. < Long-term management of Heartware biventricular assist devices (BIVADs) using low-molecular-weight heparin is possible.

Division of Neurosurgery, Tane General Hospital, Osaka, Japan.

We present a rare case of cardiac malignant fibrous histiocytoma (MFH; undifferentiated pleomorphic sarcoma); to date, fewer than 100 cases of cardiac MFH have been reported. In this case, transthoracic echocardiography revealed cardiac tumors in the left atrium (LA) of a 53-year-old woman with a 3-month history of worsening dyspnea; the largest tumor was found to protrude through the mitral valve in diastole, causing stenosis. Three of the four tumors were resected during emergency surgery; however, the residual tumor extension into the left pulmonary vein could not be removed. Read More

Undifferentiated pleomorphic sarcoma (UPS), previously known as malignant fibrous histiocytoma, is a neoplasm that occurs most often in the extremities, trunk, and retroperitoneum. Rarely, UPS can occur in the cardiac chambers and great vessels. The diagnosis of UPS is difficult to establish with noninvasive imaging techniques, and these tumors may be mistaken for benign neoplasms preoperatively. Read More

Cardiology 4, Cardio-thoracic-vascular Department, Niguarda Cà Granda Hospital, Milan, Italy.

A 47-year-old male was admitted to hospital for severe pericardial effusion; he had undergone surgical removal of cutaneous melanoma 10 years before. Echocardiography-guided pericardiocentesis revealed the presence of intramyocardial masses, which were better defined and characterized, together with pericardial involvement, by cardiac magnetic resonance. Pericardial fluid drained was negative for malignant cells, so video-assisted thoracoscopy was performed and pathologic tissue was biopsied, leading to the diagnosis of metastatic melanoma.

Pushing and loss of elastic fibers are highly specific for melanoma and rare in melanocytic nevi.

Arch Dermatol Res 2018 Dec 13. Epub 2018 Dec 13.

Dermatology Department, Inselspital Bern University Hospital, University of Bern, Freiburgstrasse, 3010, Bern, Switzerland.

The histopathological differentiation of melanocytic nevi from malignant melanoma (MM) is based on well-known criteria, and is straightforward in the vast majority of cases. However, there are few cases of melanocytic lesions (ML), the diagnosis of which is very challenging or even impossible. Here we have studied several morphological characteristics with particular focus on elastic fibers (EF) to identify features, helpful for the distinction between nevi and MM. Read More
