Sick? Antibiotics aren’t always the answer

Hennepin County Medical Center (HCMC) recently initiated an Antibiotic Stewardship Program (ASP) as a result of two global phenomena: 1) the emergence of multi-drug resistant organisms and 2) a failure to develop new anti-infective agents. 

Outsmarting the bugs

Antibiotic resistance is the ability of a microbe to outsmart or evade the current arsenal of antibiotic drugs available. There are other organisms such as viruses and fungi that cause illness, but antibiotics aren’t effective against them.

“The ‘drivers’ of resistance are many, but we know that the more an antibiotic is used the more likely it is that an organism will find a way to ‘dodge the bullet’ and become resistant,” explains Dr. David Williams, lead physician for HCMC’s ASP. Continue reading

Cold truths about hypothermia

111960627Every Minnesotan is familiar with piling on coats, hats, mittens and other clothing to stay protected from the elements during the winter months. So far this year HCMC has treated at least 78 patients with complications from hypothermia – literally meaning “low (body) temperature.” No one plans to become hypothermic; car trouble, walking home from a party, or a slip and fall on the ice are just a few ways people inadvertently get over-exposed to the harsh cold.

Don’t get “burned” by frostbite!

Every year, the Burn Center at HCMC admits approximately 20-30 patients for treatment of frostbite.

Burn surgeons take care of injuries from extreme temperatures — both hot and cold.  Dr. Anne Lambert answers some general questions about frostbite.

What causes frostbite?

“Depending on how quickly the person gets cold, there are ice crystals forming within and around their cells, not unlike putting a piece of meat in the freezer,” explains burn surgeon Dr. Anne Lambert. “With the ice crystals forming, it decreases the blood flow and literally at some point stops the blood flow to certain points of the extremities.”

What body parts are most vulnerable to frostbite? 

“Just like everything else, our body tries to preserve the heat for its important parts, like the brain and other internal organs, so during cold temperatures, the blood vessels start to get smaller, decreasing blood flow to the distant parts of the body — like noses, ears, fingers and toes.  While these areas are the most likely body parts to be affected by frostbite, we’ve had people come in with their entire arm or leg frozen as well.”
