The authors report a case of Trimeresurus albolabris (white-lipped green pit viper) bite in a 6-year-old girl living in rural Yuen Long. Despite repeated use of Agkistrodon halys antivenin, the patient developed severe coagulopathy with defibrination syndrome on the fourth day of envenomation, which was also refractory to therapy with fresh frozen plasma. When treatment was switched to green pi...

5. Isbister GK, Gray MR. White-tail spider bite: a prospective study of 130 definite bites by Lampona species. 'Mobile phone sign' in early vitamin B12 deficiency Sir, I greatly enjoyed the letter from Kozak and Schattner regarding 'Mobile Phone Sign' in early vitamin B12 deficiency. 1 I would, however, like to make one comment. I note that the patient reported in the letter was treated (succes...

Cognitive behavioural therapy (CBT) can be an effective treatment for spider phobia, but the underlying neural correlates of therapeutic change are yet to be specified. The present study used magnetoencephalography (MEG) to study responses within the first half second, to phobogenic stimuli in a group of individuals with spider phobia prior to treatment (n=12) and then in nine of them following...

An 80-year-old man living in Fréjus in southern France had a cellulitis on the right arm (Figure 1). The patient had no fever, chills, systemic symptoms, or other clinical signs. He felt a slight pain in his arm during the night and while folding his arm, he crushed a spider. The spider’s body was immediately recovered and then identified by an entomologist (Figure 2). This typical skin lesion ...

BACKGROUND Specific phobias are among the most common anxiety disorders. Exposure therapy is the treatment of choice for specific phobias. However, not all patients respond equally well to it. Hence, current research focuses on therapeutic add-ons to increase and consolidate the effects of exposure therapy. One potential therapeutic add-on is biofeedback to increase heart rate variability (HRV)...

Brown recluse spider (Loxosceles reclusa) envenomations with subsequent necrotic skin lesions occur infrequently, and systemic loxoscelism is rarer still. We report a case of 2 successive developing necrotic lesions, each on adjacent medial aspects of the legs, secondary to presumed Loxosceles envenomation. A 31-year-old man with no significant past medical history presented to the emergency de...

Measurements of regional cerebral blood flow (rCBF) were performed in 16 women suffering from spider phobia. The non-invasive 133Xe inhalation method, giving information about the blood flow of superficial areas, was used. The subjects were studied under three conditions: during resting, when exposed to a videotape showing nature scenery, and finally when watching a video with living spiders. D...
