spider bites/fever

Arachnidism can be manifested either through the skin or systemically. The genus Loxosceles is typically associated with wide necrotic skin lesions, in some cases accompanied by a generalized affection. This is a clinical case of a 16-month-old male, with an ulcer-necrotic lesion in the inferior

Acute generalized exanthematous pustulosis (AGEP) is an acute febrile rash, usually induced by drugs, which recently has been linked to spider bite. We report a case of a male patient, 48 years old, with an erythematous rash accompanied by fever and small non-follicular pustules. He reported

Loxoscelism, characterized by high fever, vomiting, malaise, a dermonecrotic lesion, and thrombocytopenia, was diagnosed in a 3-year-old female. Clinical laboratory and dermatological signs are described. Blood test showed a transient hypercoagulable state and the presence of IgG antibodies against

Brown recluse spider bites can cause local and systemic signs, including rash, dermonecrosis, edema, hemolysis, and acute kidney failure. These are mostly attributed to sphingomyelinase D, the main toxin. To evaluate the severity of the disease in pediatric patients with and without neutropenia, we

A retrospective review was made of 35 cases of Brown Recluse spider bites treated during a period of 21 years. The most common location of the bite was on the lower limbs, particularly the thigh. The main systemic manifestations were fever, malaise and maculopapular rash, but there were no cases of

Spider bites are a worldwide problem. Brown recluse spider bites can lead to severe local or systemic clinical effects, such as edema, necrotic ulcer, rashes, fever, chills, nausea, vomiting, malaise, arthralgia, myalgia, hemolysis, leukocytosis, disseminated intravascular coagulation, renal

A previously healthy 7-year-old white boy presented to St. Louis Children's Hospital with a 1-day history of headache, malaise, temperature of 38.7 degrees C, and a progressively erythematous, tender calf with central dusky purpura. On the morning of admission, his mother noticed a 2-mm crust on the

A 28-year-old man presented with painful progressive necrosis of the skin of his left leg which was associated with general toxicity and a high fever. A working diagnosis of necrotizing arachnidism was made, but no improvement followed two weeks of therapy with analgesics, antibiotics and

OBJECTIVE To report 6 children who had severe systemic reaction after spider bites requiring pediatric intensive care unit admission and to describe their clinical presentation, hospital course, and outcome. METHODS A retrospective analysis was done to identify patients presenting with brown recluse

OBJECTIVE To classify and characterize spider bites among inquiries to the National Poison Information Center (NPIC) between 1995 and 2004, in terms of the epidemiology and clinical symptomatology. METHODS Clinical and epidemiological data were obtained from the NPIC's patient records. The following

BACKGROUND Acute generalized exanthematous pustulosis (AGEP) is a rare and severe cutaneous reaction usually triggered by drugs. Other causative factors such as viral infections are rarely involved. In this study, we report a case of AGEP caused by a spider bite. METHODS A 56-year-old woman was

A 4-year-old girl was admitted 30 hours after being bitten by a black widow spider. The presenting symptoms were restlessness, profuse perspiration, severe abdominal pain and fever, while hypertension, hematuria and ECG changes developed later. Treatment was with intravenous fluids only, and she

Latrodectism, produced by the bite of Latrodectus spiders, is worldwide distributed, occurs in hot seasons, and affects mostly men when carrying out agricultural activities. The main symptoms are muscular pain and tremors, profuse perspiration, increased lacrimal, nasal and salival secretions, and

Loxoscelism, is caused by the bite of Loxosceles laeta spiders. It has two clinical forms: cutaneous loxoscelism (CL) and viscerocutaneous loxoscelism (VCL). VCL is characterized by hematuria, hemoglobinuria, jaundice, fever and sensorial involvement. In severe cases there is massive hemolysis and

BACKGROUND Loxosceles spiders are ubiquitous and responsible for many cases of envenomation in the world. The kind rufescens is present in the Provence and Occitan regions in France. During the summer 2015, we faced many Loxosceles rufescens cases of bites having led to extensive integumental
