gas gangrene/hypoxia

Intrauterine passage of meconium is common, occurring in approximately 10-15% of term births. Uncommonly, long-standing meconium exposure is associated with umbilical vascular myonecrosis, but few studies have evaluated specific clinical and pathologic features. This is a retrospective study of 481

A 73-year-old man admitted for febrile left leg pain with dyspnea, who had poorly controlled diabetes was found on admission to have severe hypoxia and chest X-ray showed infiltrates in the middle to lower left lung. X-rays of the left leg showed gas around the knee joint. These findings suggested

Clostridium perfringens gas gangrene is a fulminant infection, and radical amputation remains the single best treatment. It has been hypothesized that rapid tissue destruction is related to tissue hypoxia secondary to toxin-induced vascular obstruction, and previous studies demonstrated that

Skeletal muscle regeneration after myonecrosis involves the activation, proliferation and fusion of myogenic cells, and a coordinated inflammatory response encompassing phagocytosis of necrotic cell debris, and the concerted synthesis of cytokines and growth factors. Myonecrosis often occurs in

A 86-year-old woman hospitalized for analysis of persistent abdominal discomfort died, apparently of myocardial infarction, shortly after admission. Autopsy revealed extensive myocarditis caused by infection with Clostridium septicum. As a portal of entry a carcinoma of the colon was found. The

The case of a man who injected turpentine intravenously in an attempt to kill himself is reported. The patient developed immediate pulmonary edema and hypoxia, followed later by cellulitis at the site of injection. Although only one death to date has been attributed to this form of chemical abuse,

Marked electrolyte abnormalities characterized by profound hyperkalemia, hyponatremia, hypocalcemia, and hyperphosphatemia were noted in 4 neonatal foals with acute rhabdomyolysis and pigmenturia. In 2 foals, rhabdomyolysis developed 4-6 days after admission for dysmaturity, and in 2 foals,

Three groups, each of four sheep, were randomly allocated under blinded conditions to receive the beta-adrenoceptor agonists, salbutamol, fenoterol or isoprenaline, in doses of 0.5, 2, 8, 32 and 128 micrograms/kg intravenously at 15-minute intervals. A separate group of four animals received equal

Myotoxins present in Bothrops venom disrupt the sarcolemma of muscle fibers leading to the release of sarcoplasmic proteins and loss of muscle homeostasis. Myonecrosis and tissue anoxia induced by vascularization impairment can lead to amputation or motor functional deficit. The objective of this

Anaerobic soft tissue infections are still life threatening infections. Although their frequency is actually moderate; they remain severe because physicians are often insufficiently aware of them. Although the classification between myonecrosis and necrotizing fasciitis is still valid, these

OBJECTIVE To determine whether hyperbaric oxygen (HBO) therapy is an effective adjunct treatment for hypoxic wounds. METHODS We identified studies from technology assessment reports on HBO and a MEDLINE search from mid-1998 to August 2001. We accepted randomized controlled trials (RCTs), cohorts,

War wounds are the most complex type of non-targeted injuries due to uncontrolled tissue damage of varied and multifold localizations, exposing sterile body areas to contamination with a huge amount of bacteria. Wound contamination is caused by both the host microflora and exogenous agents from the

Hypoxia in solid tumors is a major obstacle in conventional treatment because of inefficient delivery of therapeutic agents to the lesions, but offers the potential for anaerobic bacterial colonization that can lead to tumor destruction. We have previously reported a recombinant Clostridium

Group A streptococcal necrotizing fasciitis/myonecrosis and Clostridium perfringens gas gangrene are two of the most fulminant gram-positive infections in humans. Tissue destruction associated with these infections progresses rapidly to involve an entire extremity. Multiple-organ failure is common,
