Spider Bites
Infectious Disease Epidemiology Section Office of Public Health, Louisiana Dept of Health & Hospitals 800-256-2748 (24 hr number) www.infectiousdisease.dhh.louisiana.gov SPIDER BITES Revised 6/13/2007 Epidemiology There are over 3,000 species of spiders native to the United States. Due to fragility or inadequate length of fangs, only a limited number of species are capable of inflicting noticeable wounds on human beings, although several small species of spiders are able to bite humans, but with little or no demonstrable effect. The final determination of etiology of 80% of suspected spider bites in the U.S. is, in fact, an alternate diagnosis. Therefore the perceived risk of spider bites far exceeds actual risk. Tick bites, chemical burns, lesions from poison ivy or oak, cutaneous anthrax, diabetic ulcer, erythema migrans from Lyme disease, erythema from Rocky Mountain Spotted Fever, sporotrichosis, Staphylococcus infections, Stephens Johnson syndrome, syphilitic chancre, thromboembolic effects of Leishmaniasis, toxic epidermal necrolyis, shingles, early chicken pox lesions, bites from other arthropods and idiopathic dermal necrosis have all been misdiagnosed as spider bites. Almost all bites from spiders are inflicted by the spider in self defense, when a human inadvertently upsets or invades the spider’s space. Of spiders in the United States capable of biting, only a few are considered dangerous to human beings. Bites from the following species of spiders can result in serious sequelae: Louisiana Office of Public Health – Infectious Disease Epidemiology Section Page 1 of 14 The Brown Recluse: Loxosceles reclusa Photo Courtesy of the Texas Department of State Health Services The most common species associated with medically important spider bites: • Physical characteristics o Length: Approximately 1 inch o Appearance: A violin shaped mark can be visualized on the dorsum (top). -

Homeowner Guide to Scorpions and Their Relatives
HOMEOWNER Guide to by Edward John Bechinski, Dennis J. Schotzko, and Craig R. Baird CIS 1168 Scorpions and their relatives “Arachnid” is the scientific classification category for all eight-legged relatives of insects. Spiders are the biggest group of arachnids, with nearly 3800 species known from the U.S and Canada. But the arachnid category includes other types of eight-legged creatures that sometime cause concern. Some of Idaho’s non-spider arachnids – such as scorpions -- pose potential threats to human health. Two related non-spider arachnids – sun scorpions and pseudoscorpions – look fearsome but are entirely harmless. This publication will help you identify these three groups and understand the threats they pose. All three of these groups almost always are seen as lone individuals that do not require any control. Scorpions IDENTIFICATION AND BIOLOGY FLUORESCENT SCORPIONS Scorpions are easily identified by their claw-like pincers at the The bodies of some scorpions – normally pale tan to darker red-brown – front of the head and their thin, many-segmented abdomen that glow yellow-green when exposed to ultraviolet light.

Scorpions primarily occur in the sagebrush desert of the southern half of Idaho, but one species – the northern scorpion (Paruroctonus boreus)– occurs as far north as Lewiston, along the Snake River canyon of north-central Idaho. -

Giant Whip Scorpion Mastigoproctus Giganteus Giganteus (Lucas, 1835) (Arachnida: Thelyphonida (=Uropygi): Thelyphonidae) 1 William H
EENY493 Giant Whip Scorpion Mastigoproctus giganteus giganteus (Lucas, 1835) (Arachnida: Thelyphonida (=Uropygi): Thelyphonidae) 1 William H. Kern and Ralph E. Mitchell2 Introduction shrimp can deliver to an unsuspecting finger during sorting of the shrimp from the by-catch. The only whip scorpion found in the United States is the giant whip scorpion, Mastigoproctus giganteus giganteus (Lucas). The giant whip scorpion is also known as the ‘vinegaroon’ or ‘grampus’ in some local regions where they occur. To encounter a giant whip scorpion for the first time can be an alarming experience! What seems like a miniature monster from a horror movie is really a fairly benign creature. While called a scorpion, this arachnid has neither the venom-filled stinger found in scorpions nor the venomous bite found in some spiders. One very distinct and curious feature of whip scorpions is its long thin caudal appendage, which is directly related to their common name “whip-scorpion.” The common name ‘vinegaroon’ is related to their ability to give off a spray of concentrated (85%) acetic acid from the base of the whip-like tail. This produces that tell-tale vinegar-like scent. The common name ‘grampus’ may be related to the mantis shrimp, also called the grampus. The mantis shrimp Figure 1. The giant whip scorpion or ‘vingaroon’, Mastigoproctus is a marine crustacean that can deliver a painful wound giganteus giganteus (Lucas). Credits: R.

Arthropod Envenomations: Immunologic and Toxicologic Considerations Cyrus Rangan, MD, FAAP, ACMT
Emergency Department Evaluation and Treatment for Children With Arthropod Envenomations: Immunologic and Toxicologic Considerations Cyrus Rangan, MD, FAAP, ACMT Arthropod envenomations are a significant cause of environmental injury in children. Bees, wasps, and spiders inflict injury via specialized venoms with a broad range of components, mechanisms, and potential treatments. Immunologic and toxicologic considerations in the evaluation and management of arthropod envenomations are important for the under- standing of the progression of envenomations, prompt diagnosis of severe conditions including anaphylaxis, and the use of antivenom in selected cases. Clin Ped Emerg Med 8:104-109 ª 2007 Published by Elsevier Inc.

Bees are attracted to carbon dioxide (hence, United States in 2005 [1]. The phylum Arthropoda the predilection for bees to fly around the facial area), includes 2 clinically important classes: Insecta (order: bright colors (ie, clothing), and sweet odors (ie, Hymenoptera—bees, wasps, yellow jackets, and ants), perfumes, fragrances). Children commonly believe that and Arachnida (ticks, scorpions, and spiders). Virtually bees are aggressive insects, but they are mostly docile all arthropods possess some form of venom for immobi- creatures; indeed, the sometimes fearful behavior of lization and digestion of prey, yet only a select few species children around a nearby bee may increase the risk of a have developed venom delivery mechanisms capable of sting. Mass envenomations may occur when a hive is poisoning humans [2]. Pathophysiologic mechanisms of physically disturbed by children throwing rocks or other venom vary considerably among arthropods, and clinical objects at the hive [3]. -
Instruction Sheet: Bee Sting, Local Reaction
University of North Carolina Wilmington Abrons Student Health Center INSTRUCTION SHEET: BEE STING, LOCAL REACTION The Student Health Provider has diagnosed a mild allergic reaction to a bee/wasp sting. Fortunately, most bee stings are not serious and cause only temporary swelling, redness, and pain at the sting site. Rarely, a whole-body allergic reaction occurs; shock can result. The stinger, if still in the wound, should be removed; if the stinger is left in place, bee toxin continues to enter the body, increasing the reaction. A stinger should be removed with a piece of paper or credit card, using a sideways scraping motion. A pair of tweezers can also be used to remove the stinger, but try not to squeeze the stinger, or more toxin can be pushed inside the wound. Realize that swelling may increase at first, even with treatment. Measures can be taken, however, to minimize the reaction to bee stings. MEASURES YOU SHOULD TAKE TO HELP TREAT YOUR BEE STING: 1. Rest and elevate the affected body part. Rest and elevation help reduce swelling and pain. 2. Apply cold packs to the area off-and-on for the first 24 hours after injury. Cold helps ease discomfort, and minimizes additional swelling. Do not apply ice directly to the area, causing discomfort. Rather, aim for coolness, yet comfort, applying a layer or two of cloth between the cold pack and affected area. 3. Take over-the-counter antihistamines: In the morning, take a non-sedating antihistamine such as loratadine, 10 mg daily. At night, take diphenhydramine (Benadryl), 25 mg, 1 or 2 every 6 hours for itching and swelling. -
