Dislocated Shoulder Reduction in Wilderness

The Medicine for the Outdoors blog by Paul Auerbach has produced yet another great article! This tip on a technique for reducing a dislocated shoulder comes courtesy of Dr. Jeremy Joslin.

The technique he describes is called the Milch technique and his advice and descriptions of the procedure are very well written. Anybody who ventures off a paved road should have a read through the tips on this blog.

Thanks for a great article!

DEET in Pregnancy

I ran accross a good question about someone concerned with DEET use in pregnancy.  This is a very good question and a pregnant woman should always be aware of what she is doing and taking, with respect to the health of her baby. By the way, the article was over at BootsnAll Travel Health Forum.

DEET is safe for use by pregnant and breast feeding women, following manufacturer guidelines. CMAJ • August 5, 2003; 169 (3) “DEET-based insect repellents: safety implications for children and pregnant and lactating women” by: Gideon Koren, Doreen Matsui and Benoit Bailey.

Another fantastic article on Mosquito Bite prevention can be found here: Mosquitoes and Mosquito Repellents: A Clinician’s Guide by Mark S. Fradin, MD. This article is in Annals of Internal Medicine, 1 June 1998 | Volume 128 Issue 11 | Pages 931-940.

These are my two main sources when I need to refer about safety of mosquito repellents.

There are a few other options, as well. Avon Skin-so-soft lotion has some anti-mozzi effects and is well tolerated in children and adults. The downside to this is that it requires more frequent applications for decent protection. The anti-mosquito properties are believed to come from either fragrance of the cream or the chemicals it contains, benzophenone and diisopropyl adipate. Citronella oil should aslo be mentioned, although it is not proven to be as effective as DEET.

DEET is a very well know compound and has a wide safety profile. The few reported adverse events associated with DEET have largely been in pediatric populations and associated with improper use (using far too much and too often). For more information you can visit another post on mosquito bite prevention.

Water Purification Bag

There is a interesting new article over at Outdoorsmagic.com. A company called Pure Hydration has released their “Thirst Aid Bag”.

The bag, made from Armour Weave Technology, makes use of the company’s Aquapure Traveller filter. About the size of a water bottle, the filter has already been approved by London School of Tropical Medicine and claims to kill viruses and bacteria.

Chiefly designed for emergency use in disaster areas, the bag will have obvious uses in the hiking world, as well.

I am always interested in a small and effective water filter.

DesertUSA.com Survival Article

I grew up in Southern Arizona, the center of the Sonoran Desert. For people not used to the heat down there, it can be overwhelming. A really cool website, called DesertUSA.com, has an article by Felice Prage about “Surviving in the Sonoran Desert“.

The article contains loads of good information from sun protection and safe desert travel to special survival gear for deserts. I really liked it!

I have a page on Hot Climates over at AdventureDoc.org

Cholera Updates: Iraq and Vietnam

Iraq and Vietnam seem to have the unfortunate position of “top cholera hotspots” according to ProMed’s new diarrheal and cholera updates.

I was just asked a question, from a traveler going to Vietnam, about advice and safety. For knowledge of traveler’s diarrhea, you can visit the Adventure Doc Traveler’s Diarrhea Page.

Iraq:
ProMed stated that Iraq is facing a “Health Catastrophe” in Baghdad. Cholera cases continue to soar, mostly in the eastern part of the city. Poor sanitation is cited as the biggest factor to overcoming this outbreak. A November report form the UN stated 4569 new cases for the year and 22 deaths, all from cholera. Sanitation, clean drinking water, hand washing and prompt recognition of diarrhea followed by copius oral rehydration are the cornerstones to combating cholera.

Vietnam:
Another on-going epidemic with 1941 cases of acute diarrhea in northern provinces of Vietnam, of which 261 tested positive for cholera.

“According to Nguyen Tran Hien, director of the National Institute of Hygiene and Epidemiology, the results from tests on vegetables and water from areas where cases of cholera were identified found no sign of the cholera bacterium.” Source: Promed Mail.

Ha Tay and Ha Noi provinces are hardest hit.  Ha Tay, being a large producer of food products for the country, is in a prime spot for transmitting the disease all over the country.

Government inspectors are currently assesing the sitituation and giving out hand sanitizer and latex gloves to citizens in the hardest hit provinces.

The cholera vaccine is currently marketed by:
Dukoral ®
SBL Vaccin AB,
SE-105 21 Stockholm, Sweden
telephone +46-8-7351000,
e-mail: info@sblvaccines.se
website: http://www.sblvaccines.se

Although the CDC does not advise the vaccine for routine travelers. See more on the CDC cholera page. Previous vaccines have been notorious for causing intussusception in children. Intussusception is a cause for abdominal pain and bowel obstruction. This occurs, most commonly, when the bowel/intestine “telescopes” into itself, similiar to closing a spyglass. E-medicine has a great article about it.

Fatal Trypanosomiasis in Serengeti

The ISTM/Geo Sentinel has a news release about a fatal case of African Trypanosomiasis in a tourist traveling through the Serengeti. The victim was dead 6 days after being bitten by the notorious Tse Tse Fly, carrier of “African Sleeping Sickness”.

Apparently, she was initially diagnosed, by blood smear, as a case of malaria. This delay in correct diagnosis cost valuable time and the patient died in an Intensive Care Unit in a Niarobi hospital. This is the first case of African Trypanosomiasis, in a Serengeti Tourist, since 2001.

She was reported to acquire the infection while traveling through Tanzania.

The causative agent in Sleeping Sickness is Trypanosoma Brucei Gambiense, found is Western Africa, in areas where Glossinia (tsetse) species live. T.B. Rhodsiense is found in scattered spots of Eastern Africa and more associate with sylvatic cycles involving wild deer and range animals.

Nicknamed “Sleeping Sickness”, mental status changes are common. The acute nature of the disease suggest the East African form, T.B. Rhodiense.
