Wet gangrene developed in all 4 limbs following repair of a rupture in the lower urinary tract in a 2-week-old foal. Dehydration and hypoxemia are suspected as the inciting causes of the necrosis.
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
Ventricular tachycardia occurs with myocardial ischaemia, hypoxia, hypercarbia, hypokalaemia, and digitalis toxicity. We report recurrent ventricular tachycardia occurring in a patient with gangrene of the lower extremities in whom none of the common aetiologies for dysrhythmia could be
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
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
Transcutaneous oxygen tension at 44 degree C and maximal isotope clearance (90m Tc-pretechnetate + histramine) just proximal to the 1st toe and systolic toe blood pressure (strain gauge) were studied on a tilt table in patients with various degrees of obstructive arteriosclerotic disease. In legs
OBJECTIVE
Hyperbaric oxygen therapy (HBO) has been successfully used in several disorders derived from tissue hypoxia, due to the extra oxygen supply to the tissues it enables. In this manuscript we performed a systematic review including all the existing data published until 2010 about HBO in
Transcutaneous oxygen tension Ptco2 is directly related to skin oxygen delivery. Regional transcutaneous oximetry ( RTO ) compares peripheral and truncal (Ptco2), yielding a regional perfusion index indicative of local limb perfusion. The relative diagnostic values of RTO , Doppler ankle-brachial
A paradoxical embolus associated with orthodeoxia-platypnea syndrome and intracardiac shunting is extremely uncommon. We present a patient who was found to have a positional change in desaturation after a right pneumonectomy who suffered from gangrene of the right foot and simultaneous deep venous
1. Prolonged exposure of the extremities to cold insufficient to cause tissue freezing produces a well-defined syndrome. 'Immersion foot' is one of the descriptive but inaccurate terms applied to this syndrome. The clinical features, aetiology, pathology, prevention, and treatment of immersion foot
Extracts of annual ryegrass (Lolium rigidum) infected with Anguina sp. and Corynebacterium sp., and associated with an outbreak of annual ryegrass toxicity in sheep, were administered to 2-week-old rats by a single intraperitoneal injection. Rats that received a lethal dose of toxin developed
A total 37 patients suffering from end stage-IV Fontaine (CLI and diabetic foot) with an ulcerated limb in whom all previous therapeutic strategies failed (e.g. surgical revascularization and endovascular repair) were selected and underwent local transplantation of Autologous Bone Marrow Stem Cells
1. Enteral feeding and factors promoting hypoxia and ischaemia of the gut are thought to cause necrotising enterocolitis of the newborn but have not been proven as factors in the pathogenesis of NEC. Enteral feeding may be started in principle on the first day of life at a rate of 10-20 ml/kg/day.
Introduction: Management of acute abdomen during COVID-19 pandemic may be challenging.
Presentation of case: A 42-year old man was hospitalized for Covid-19 pneumonia. Fever,
The clinical manifestations and prognosis of peripheral vascular disease (PVD) depend upon the severity of limb hypoxia. Transcutaneous oxygen tension (Ptco2) is related to tissue oxygenation, but limb Ptco2 varies with changes in systemic as well as peripheral oxygen delivery (Do2). Previously we
