background: in order to describe the patients and evaluate the effectiveness of treatments for widow spider envenomation, investigators require a reliable assessment tool. in this paper, the development of a clinical index for measuring the widow spider bite severity, latrodectus envenomation severity score (less), is described. methods: according to the valid methods for index development, a d...

We carefully analyze the WFPC2 and STIS images of GRB970228. We measure magnitudes for the GRB970228 point source component in the WFPC2 images of V = 26.20 −0.13, Ic = 23.94 +0.10 −0.09 and V = 26.52 +0.16 −0.18, Ic = 24.31 +0.15 −0.11 on March 26 and April 7, respectively; and Rc = 27.09 +0.14 −0.14 on September 4 in the STIS image. For the extended component, we measure magnitudes of Rc = 25...

BACKGROUND Brown recluse spider bites cause significant trauma via their tissue toxic venom. Diagnosis of these injuries and envenomation is difficult and many times presumptive. Treatment is varied and dependent upon presentation and course of injury. MATERIALS AND METHODS We present a case of a previously unreported incidence of osteomyelitis of the mandible as a result of a brown recluse s...

2015 © American Water Works Association JOURNAL AWWA OCTOBER 2015 | 107:10 Tularemia is an acute febrile zoonotic disease caused by the bacterium Francisella tularensis. Shortly after the initial isolation of the organism in Tulare County, Calif. (McCoy & Chapin 1912), the first case of a human infection was reported from Cincinnati, Ohio (Wherry & Lamb 1914). The first documented waterborne ou...

Congenital agenesis of lumbar vertebrae was diagnosed in a day-old female lamb based on radiology and clinical examinations. There was no neurological deficit in hindlimb and forelimb associated with standing disability. Radiography of the abdominal region revealed absence of lumbar vertebrae. Necropsy confirmed clinical and radiographic results. No other anomaly or agenesis was seen macroscopi...

Successful cognitive behavior therapy (CBT) for spider phobia is able to change patients' brain activation during visual symptom provocation. The present voxel-based morphometry study investigated whether this therapy approach can additionally affect brain structure. We analyzed gray matter volume of 12 spider-phobic patients prior to CBT and in a six-month follow-up investigation, and contrast...

Spider veins (also known as spider hemangiomas) unlike varicose veins (dilated pre-existing veins) are acquired lesions caused by venous hypertension leading to proliferation of blood vessels in the skin and subcutaneous tissues due to the release of endothelial growth factors causing vascular neogenesis. More than 60% of the patients with spider veins of the legs have significant symptoms incl...
