Some of the world's most dangerous spiders have been certified in some areas of Iran. Spider bites are common in some geographical areas, and are sporadic in some regions. Spider bites can be classified as latrodectism or loxoscelism. If the patient had not seen the spider, the clinical manifestations of latrodectism could be easily mistaken for other types of bite or sting; or an infectious di...

Loxoscelism is a rare but often underestimated cause of dermonecrosis in emergency departments. Different kinds of treatment are proposed in literature, but a shared management protocol is not yet available. We propose a therapeutic protocol considering a case which occurred in our emergency department, managed with the support of the Poison Control Center (PCC) and the Hyperbaric Unit. In part...

Loxosceles laeta spiders were captured in the West zone of São Paulo City, this being the first record of the specie in this area. Since loxoscelism is an important public health problem in the South region of Brazil, it is necessary to investigate the presence of this spider in São Paulo City.

Loxoscelism, the term used to describe lesions and clinical manifestations induced by brown spider's venom (Loxosceles genus), has attracted much attention over the last years. Brown spider bites have been reported to cause a local and acute inflammatory reaction that may evolve to dermonecrosis (a hallmark of envenomation) and hemorrhage at the bite site, besides systemic manifestations such a...

Introduction: Loxoscelism is a medical condition resulting from the envenomation by recluse spiders (Loxoscelesspp.), which could lead to necrotic tissue symptoms. The only species of this genus recorded from Iran, Loxosceles rufescens, or the Mediterranean recluse spider, has a cosmopolitan distribution and have already been recorded from numerous parts of Iran, including Bandar Abbas. This st...

loxosceles rufescens , commonly known as the mediterranean recluse or mediterranean fiddle-back spider is recorded from iran for the first time. the genus loxosceles contains 103 accepted species, two of them (including l. rufescens ) are cosmopolitan. all loxosceles species tested so far possess necrotic venoms, which is a unique characteristic among the order araneae. considering this charact...

BACKGROUND Brown recluse spider bites are a serious medical problem in the southeastern United States. Although most bites are asymptomatic, envenomation can result in a constellation of systemic symptoms referred to as loxoscelism. Patients can also develop necrotic skin ulcers (necrotic arachnidism). These ulcers are often difficult to heal and can require skin grafting or amputation of the b...
