Frosts are also affected by varicose veins, cardiovascular diseases, obliterating endarteritis
(gradual narrowing of the vessels, mainly the arteries of the legs), diabetes mellitus with diabetic polyneuropathy (lowering the threshold of pain and temperature sensitivity of the upper and lower extremities).
A number of studies showed pathological changes of the placenta, such as villous infarcts, hypovascularity, fibrosis, and thickening of the basal membrane, obliterative endarteritis
, cytotrophoblast proliferation, and syncytiotrophoblasts knotting in patients with IUGR.
Photomicrography of the kidney of an animal of group I (sham) in the area not subjected to ischemia, showing the endarteritis
obliterans (EO) associated with interstitial nephritis (IN).
This necrosis is secondary to thrombosis of small vessels, which is due to endarteritis
obliterans caused by the spread of microorganisms into the subcutaneous space that in addition to generating local edema, hypoxia, decrease in local blood supply, which helps anaerobic bacterial overgrowth.
5) The same study further noted that previous chemoradiation, which is an independent predictor of OCF and PCF development, likely exerted direct toxic effects on tissue and caused tissue hypoxia due to endarteritis
obliterans and fibrosis, both of which led to poor tissue healing.
Typical features of syphilis, such as endarteritis
and phlebitis, were not easy to see in this particular case due to extensive necrosis.
Both the isolated endarteritis
group and the positive control group were treated with corticosteroids or T cell depleting therapy; negative controls received no treatment.
However, there are high risk, huge trauma and lots of complications, particularly systemic embolism, infective endarteritis
, cerebral abscess, and rupture of aneurysmal communications, with this operation.
2) Microarray techniques revealed a virulence plasmid related to Salmonella choleraesuis (group C), known as the most frequent serotype involved in infectious endarteritis
The disease process involves an entry point for microorganisms (rupture of skin) with synergistic polymicrobial infection leading to obliterative endarteritis
of subcutaneous arteries, necrosis of skin, subcutaneous tissues, fat, muscles, fasciae with suppuration and gas formation.
The disintegrating larvae release antigens that incite an initial endarteritis
and localized pneumonitis followed by an organizing granuloma rather than causing an ischemic pulmonary infarct like a pulmonary artery embolus.
El diagnostico es esencialmente clinico, sin embargo se pueden realizar biopsias de piel que, aunque a veces son normales, pueden mostrar oclusion de arteriolas por la proliferacion intimal, configurando un patron de endarteritis
obliterante con posible trombo que ocupa la luz arterial
