necrotizing fasciitis

necrotizing fasciitis and got the famous title of a "flesh-eating infection/bacteria"! Typically the infection enters the body through a break in the skin such as a cut or burn.
Unlike cellulitis, necrotizing fasciitis involves the deeper layers of tissue down to the deep fascia and it is caused by anaerobic bacteria or group A streptococci.
Clinical manifestations include fever with an area of erythema.
If not treated, the tissue begins to turn gray/black (seen on the top photo). It spreads quickly and aggressively from the primary  infected area and beyond and can result in amputation, shock, and death if not treated by a combination of surgical exploration and debridement (removing the dead tissue - bottom left photo) with IV antibiotics.
This patient had undergone a fasciotomy, a limb-saving procedure where the fascia was cut to relieve tension or pressure of the underlying tissue due to extensive necrosis.

Eye injury sustained while fishing from a fishing hook. Yes, those kind of injuries happens commonly among fisherman. Many fishing hooks have barbs that make them difficult to remove if they embed in an eye. If one do catch a hook in the eye, it is important not to try to remove it yourself, as you may cause more damage. Fish hook injuries most commonly occur in the hand. The standard method used to remove them from this site is to push the barb out through the skin,snip it off ,and then rotate the shaft backwards along the entry path. If the hook is simply dragged backwards with the barb in situ it produces much greater soft tissue damage. Good vision is usually restored without complications, and wearing proper eye protection is advised.
