Tetracycline and penicillin resistant Clostridium perfringens isolated from the fangs and venom glands of Loxosceles laeta: its implications in loxoscelism
Clinical characterization of dermonecrotic loxoscelism
in equine of Cordoba, Colombia
In all of the cases analyzed, a differential diagnosis was performed between EG and Warfarin-induced skin necrosis, cocaine-induced skin necrosis, calciphylaxis, septic emboli, loxoscelism
, diabetic microangiopathy, disseminated intravascular coagulation, necrotizing vasculitis, paraneoplastic extensive necrotizing vasculitis, pyoderma gangrenosum, livedoid vasculopathy, necrotizing fasciitis, and necrosis secondary to the use of vasoactive drugs.
: Case Report and Literature Review
In a small percentage of patients, violin spider bites may present with severe, sometimes life-threatening systemic illness with haemolysis, coagulopathy, shock, renal failure, and multiple organ damage (loxoscelism
intermedia is widespread in human domestic habitats and its bite causes a public health problem known as loxoscelism
(Fischer, 1994; Fischer and VasconcellosNeto, 2005a; Marques-da-Silva et al., 2006).
All of these are often falsely attributed to loxoscelism
In fact, these critical molecular messengers are involved in the genesis of a constellation of human pathophysiological phenomena: stroke, pericarditis, peritonitis, loxoscelism
, meningitis, sepsis, coagulation disorders, myocardial dysfunction, and circulatory collapse (16-19).
There are two types of skin loxoscelism
, the necrotic (75%) and edematous (4%) .
Because some bites cause systemic loxoscelism
, clinicians should be familiar with its manifestations.
Reported treatments for loxoscelism
include hyperbaric oxygen, dapsone, antihistamines, antibiotics, dextran, glucocorticosteroids, vasodilators, heparin, nitroglycerin, electric shock, curettage, and surgical excision, but "none of these has been proved effective," Dr.
