Association of Valproic Acid Use, a Potent Histone Deacetylase Inhibitor, and Melanoma Risk.

Histone deacetylase inhibitors, including valproic acid, selectively induce cellular differentiation and apoptosis in melanoma cells. No published pharmacoepidemiologic studies have explored the association between valproic acid use and melanoma risk. We conducted a retrospective cohort study of adult white Kaiser Permanente Northern California members (n = 2,213,845) from 1997 to 2012 to examine the association between valproic acid use and melanoma risk.

Wilderness Dermatology: Bugs, Plants, and Other Nuisances That May Ruin Your Hike.

Spending time outdoors can be rewarding. However, exposure to the sun, insect bites, and plant exposures may result in a wide range of dermatologic manifestations. In this article, we describe potential cutaneous manifestations of common wilderness exposures in New England including photodermatoses from prolonged sun exposure, phytodermatoses from plant exposures, and arthropod-bite reactions from common insects (mosquitos, spiders, ticks, hymenoptera, mites and chiggers).

Medicinal plants with traditional use: Ethnobotany in the Indian subcontinent.

Traditional medicine uses cultural knowledge and practices to promote health maintenance as well as diagnose and treat disease. In developing countries, the majority of people rely on traditional medicines; however, many of these practices have not been rigorously and systematically studied or reported. We review the current understanding and research behind traditional therapies prevalent in the Indian subcontinent, including mind-body and energy-based healing, botanical medicine, and herbal remedies.

Information needs of Botswana health care workers and perceptions of wikipedia.

Background: Since the UN Human Rights Council's recognition on the subject in 2011, the right to access the Internet and information is now considered one of the most basic human rights of global citizens [1,2]. Despite this, an information gap between developed and resource-limited countries remains, and there is scant research on actual information needs of workers themselves. The Republic of Botswana represents a fertile ground to address existing gaps in research, policy, and practice, due to its demonstrated gap in access to information and specialists among rural health care workers (HCWs), burgeoning mHealth capacity, and a timely offer from Orange Telecommunications to access Wikipedia for free on mobile platforms for Botswana subscribers.

Using TV white space spectrum to practise telemedicine: A promising technology to enhance broadband internet connectivity within healthcare facilities in rural regions of developing countries.

The following correspondence provides an overview of TV White Space (TVWS) technology, regulations, and potential applications to the health care sector. This report also introduces "Project Kgolagano," a Botswana-based initiative representing the first endeavour to utilize TVWS internet connection for practising telemedicine. TV "white space" refers to the previously unused, wasted spectrum within TV radiofrequency channels that can now be leveraged to obtain broadband internet access.
