Frostbite
With the cold months here people need to be made aware of injuries that may occur during these months. Exposure to a temperature below freezing usually leads to severe soft tissue damage (Figure 1). How does the body protect itself from cold? Thermoregulation The body has the ability to maintain a core body temperature by the process of thermoregulation. During extreme cold, the body receives a signal from sensory receptors. For example, there receptors are present in the hands or the feet (Figure 2). These sensory receptors will respond to the cold and send a signal up to the brain. The posterior hypothalamus is respo...

Trusting Your Gut: Diagnosis and Management of Clostridium septicum Infections
Clostridium septicum is a Gram-positive anaerobic bacillus that causes serious, life-threatening infections, including aggressive septicemia and myonecrosis. Clostridial myonecrosis can be broadly classified into two defined clinical presentations: traumatic and spontaneous. Clostridium perfringens is the most common cause of traumatic myonecrosis, while C. septicum is the most common etiological agent of spontaneous myonecrosis. Although rarely clinically encountered, C. septicum infections are often fatal. (Source: Clinical Microbiology Newsletter)

Tourniquets in Field Management of Active Bleeding
This study was groundbreaking. First, it was a prospective study; second, it found a complication rate of 1.7% limited to nerve palsies. These updated findings on complications of the device have helped to allay prior fears of morbidity that deterred tourniquet use. Following suit, the civilian community conducted its own research. Yielding low complication rates and high potential benefits, this research bolstered the recommendation for aggressive early tourniquet use.7 Mirroring the wave of change in military protocols, by 2012 some large metropolitan areas began equipping ambulances with commercial tourniquets and ...

Gate for bacterial toxins found
(University of Freiburg) Prof. Dr. Dr. Klaus Aktories and Dr. Panagiotis Papatheodorou from the University of Freiburg have discovered the receptor responsible for smuggling the toxin of the bacterium Clostridium perfringens into the cell. The TpeL toxin is formed by C. perfringens, a pathogen that causes gas gangrene and food poisoning. It is very similar to the toxins of many other hospital germs of the genus Clostridium. Aktories is member of the BIOSS Centre for Biological Signalling Studies. (Source: EurekAlert! - Biology)
