Ski season is upon us. There is no greater relief on a frigid winter day than warming cold, painful fingers and toes. In a recent issue of Wilderness and Environmental Medicine (2009;20:33-38), William Sands, Ph.D. and colleagues authored an article entitled, “Comparison of Commercially Available Disposable Chemical Hand and Foot Warmers.” The objective of their study was to characterize the thermal behaviors of 14 commercially available hand and foot warmers.
The warmers were studied in pairs in a laboratory setting, not in frigid conditions. Each warmer was monitored with a rapidly-responding thermister to determine its external temperature. One of each pair of warmers was placed in a boot or glove. Temperature was recorded until the heat output of the devices ceased and the temperature was determined to be identical to ambient temperature.
The results were quite interesting. There was variability both within and between manufacturers and types of warmers. Some of the devices exceeded packaging claims, while others fell short. The greater the mass of the warmer, the longer the duration of heat production. Read more »

From the Journal of the American Mosquito Control Association comes an interesting article by BC Muller and colleagues (J Am Mosquito Control Assoc 2008;24:154-160) entitled “Ability of Essential Oil Candles to Repel Biting Insects in High and Low Biting Pressure Environments.”
Anyone who has spent much time outdoors, whether on a camping trip or enjoying a backyard picnic, has encountered the scourge of biting insects, and in particular, mosquitoes. There is no good reason to be bitten by a mosquito, and many very important reasons to avoid them, namely, the risk of transmission of infectious disease, such as dengue, West Nile virus, malaria and so on. My first experiences with mosquito repellents were the ubiquitous green (“snake”) coils and candle products, which were supposed to keep the critters away. No surprise – some of them work well and some of them do not work so well. Read more »

In a recent issue of Wilderness & Environmental Medicine (Volume 20, Number 2, 2009), Anne-Michelle Ruha and Steven Curry have written an article entitled “Recombinant Factor VIIa for Treatment of Gastrointestinal Hemorrhage Following Rattlesnake Envenomation.” This is a “case report,” meaning that this is a description of a particular medical event, rather than a study.
To open the piece, the authors observe that North American rattlesnakes possess venom with properties that can cause severe physiological effects, such as low platelet count and, on occasion. bleeding. In this report, we learn about a 44 year old man who was bitten on the index finger by an unidentified (unknown for this case) species of rattlesnake. The victim developed massive gastrointestinal bleeding that was treated eventually with a product known as recombinant factor VIIa. His initial clinical presentation included an altered level of consciousness, profoundly low blood pressure (shock), sweating, and vomiting of bright red blood. Read more »

This is the third post based upon my presentation given at the Wilderness Medical Society Annual Meeting held in Snowmass, Colorado from July 24-29, 2009. The presentation was entitled “Just When You Thought It Was Safe to Go Back in the Water.”” The topic was an overview of hazardous marine animals and it was delivered by me. In the previous post, there was information about stingrays and scorpionfishes. In this post, there is information about injuries from sea urchins incurred in the marine environment.
Sea urchins are free-living echinoderms with egg-shaped, globular or flattened bodies. They are covered by tightly arranged spines and/or triple-jawed pedicellariae, which are seizing and envenoming organs. The spines can be brittle, hollow, sharp and venom-bearing or blunt and non venom-bearing (such as with Hawaiian pencil urchins). Most persons are envenomed when they step upon or brush against an urchin. Read more »

This is the next post based upon my presentation given at the Wilderness Medical Society Annual Meeting held in Snowmass, Colorado from July 24-29, 2009. The presentation was entitled “Just When You Thought It Was Safe to Go Back in the Water.”” The topic was an overview of hazardous marine animals and it was delivered by me. In the previous post, there was information about shark attacks. In this post, there is information about envenomations incurred in the marine environment.
Marine venoms, similar to other toxins and poisons that originate in the animal and plant kingdoms, may cause a wide range of human physiological derangements. It is very important to remember that certain of these venoms, such as that elaborated by jellyfish, may invoke a serious allergic reaction.
Stingrays are a commonly incriminated group of envenoming animals. There are more than 10 species found in U.S. coastal waters, with from 1 to 4 venomous “stings” found on the top of the caudal appendage (“tail’). The spine is a serrated cartilaginous structure that houses venom glands covered by a fragile tissue sheath. Thus, when the spine enters a human victim, most commonly on the lower limb (ray is stepped upon) or upper limb (ray is handled), the tissue sheath is disrupted and venom enters the wound. Thus the injury is just a puncture/cut and an envenomation. Read more »
