Common presentations for pit viper envenomation are local edema, hypotension, and ultimately myonecrosis
Extensive areas of acute hemorrhage and myonecrosis
appeared to be related to envenomation.
Current plans to use hyperbaric oxygen at AVC include: Carbon monoxide poisoning and smoke inhalation injuries, clostridal myositis and myonecrosis
, crush injury, other acute traumatic ischemia, enhancement of healing in selected problem wounds, exceptional blood loss, intracranial abscess, necrotizing soft tissue infections (necrotizing fasciitis), osteomyelitis (refractory), skin grafts and flaps (compromised), and thermal burns.
This organism has been reported to cause several infections, including clostridial myonecrosis
(8), osteomyelitis, septic arthritis, panophthalmitis, aortitis, intraabdominal abscess, intracranial infections, and abdominal wall cellulitis.
Therefore, type A exhibits several powerful toxicities, and infection with type A may result in myonecrosis
, hemolysis, an increase in vascular permeability and platelet aggregation [25;14].
In contrast, the prognostic value of periprocedural myonecrosis
in men vs women has yielded conflicting results (19, 20).
Pathogenesis of myonecrosis
induced by crude venom and a myotoxin of Bothrops asper.
This lesion produces myonecrosis
, tissue disruption, edema, hypercontracted fibers, and inflammatory cell infiltration (especially neutrophils and macrophages) .
Chen WH, Lee PY, Ng W, Tse HF, Lau CP Aspirin resistance is associated with a high incidence of myonecrosis
after non-urgent percutaneous coronary intervention despite clopidogrel pretreatment.
Categorization of Stillbirths Intrapartum deaths Antepartum deaths Normal weight for Signs of autolysis: gestational age Skin "slips" off with touch No signs of autolysis Dermis discolored grey-brown Disarticulated calvarial bones Brown discoloration of umbilical cord Causes Causes Associated with Possibly preventable (if diagnosed (or caused by): and treated early) "Sentinel" event Placental Maternal death Hypertensive disorders Abruption Infectious Uterine rupture Bacterial: chorioamnionitis Cord accident Viral: chronic villitis Placenta or Fungal: umbilical abscesses vasa previa Parasitic: intervillositis Entrapment (malpresentation, Toxic/metabolic macrosomia, pelvic size) Maternal diabetes Birth asphyxia Meconium myonecrosis
Sepsis Other exposures: tobacco, cook smoke?
10) There is some evidence that fasciotomy may increase myonecrosis
in snake-bitten limbs.
The infection had tracked up through the rectus sheath bilaterally, with associated myonecrosis
, and complete separation of the muscle from the anterior and posterior rectus sheath fascia.
