Frostbite involves freezing of fluids inside and outside of cells that results in cell breakdown, electrolyte imbalances, and inflammation. [8] Surrounding blood vessel constriction and injury disrupts blood flow to affected tissue, which may cause tissue death . [11]
The pathological mechanism by which frostbite causes body tissue injury can be characterized by four stages: Prefreeze, freeze-thaw, vascular stasis, and the late ischemic stage. [16] Prefreeze phase: involves the cooling of tissues without ice crystal formation. [16] Freeze-thaw phase: ice-crystals form, resulting in cellular damage and death ...
Complications and death due to relapsing fever are rare. [citation needed] Tetracycline-class antibiotics are most effective. These can, however, induce a Jarisch–Herxheimer reaction in over half of those treated, producing anxiety, diaphoresis, fever, tachycardia and tachypnea with an initial pressor response followed rapidly by hypotension.
The recommended room temperature for babies is generally between 68 and 72 degrees Fahrenheit, and experts warn that overheating is linked to sudden infant death syndrome (SIDS). Liu notes that ...
Scabies and lice are at epidemic proportions, he said, but other fungal, bacterial and viral infections and parasites are also running wild. With the flood of patients, even simple cases can ...
Head lice and body lice. Malathion is approved by the US Food and Drug Administration for treatment of pediculosis. [11] [12] It is claimed to effectively kill both the eggs and the adult lice, but in fact has been shown in UK studies to be only 36% effective on head lice, and less so on their eggs. [13]
After just two minutes, heart rates reach a level more commonly expected during intense aerobic exercise testing, Franklin said. About 805,000 people in the U.S. have a heart attack every year in ...
Completely changing the clothing, washing the infested clothing in hot water, and in some cases also treating recently used bedsheets all help to prevent typhus by removing potentially infected lice. Clothes left unworn and unwashed for 7 days also result in the death of both lice and their eggs, as they have no access to a human host. [16]
