Tick Removal - Article
ABSTRACT: Many methods of tick removal that have been reported in the literature have proved to be unsatisfactory in controlled studies. Some methods may even cause harm by inducing the tick to salivate and regurgitate into the host. Ticks are best removed as soon as possible, because the risk of disease transmission increases significantly after 24 hours of attachment. The use of a blunt, medium-tipped, angled forceps offers the best results. Following tick removal, the bite area should be inspected carefully for any retained mouthparts, which should be excised. The area is then cleaned with antiseptic solution, and the patient is instructed to monitor for signs of local or systemic illness. Routine antibiotic prophylaxis following tick removal generally is not indicated but may be considered in pregnant patients or in areas endemic to tick-borne disease.
ABSTRACT: In the course of their clinical work or during leisure activity, family physicians occasionally may encounter patients with injuries from marine creatures. Poisoning, envenomation, and direct trauma are all possible in the marine environment. Ciguatera poisoning can result from ingestion of predatory fish that have accumulated biotoxins. Symptoms can be gastrointestinal or neurologic, or mixed. Management is mostly symptomatic. Scombroid poisoning results from ingestion of fish in which histamine-like substances have developed because of improper refrigeration. Gastrointestinal and systemic symptoms occur. Treatment is based on antihistamines. Envenomations from jellyfish in U.S. waters and the Caribbean are painful but rarely deadly. Household vinegar deactivates the nematocysts, and manual removal of tentacles is important. Treatment is symptomatic. Heat immersion may help with the pain. Stingrays cause localized damage and a typically severe envenomation. The venom is deactivated by heat. The stingray spine, including the venom gland, typically is difficult to remove from the victim, and radiographs may be necessary to localize the spine or fragment. Surgical dÃ©bridement occasionally is needed. Direct trauma can result from contact with marine creatures. Hemorrhage and tissue damage occasionally are severe. Infections with organisms unique to the marine environment are possible; antibiotic choices are based on location and type of injury. Shark attacks, although rare, require immediate attention.
Prevention and Treatment of Dog Bites - Article
ABSTRACT: Almost one half of all dog bites involve an animal owned by the victim's family or neighbors. A large percentage of dog bite victims are children. Although some breeds of dogs have been identified as being more aggressive than other breeds, any dog may attack when threatened. All dog bites carry a risk of infection, but immediate copious irrigation can significantly decrease that risk. Assessment for the risk of tetanus and rabies virus infection, and subsequent selection of prophylactic antibiotics, are essential in the management of dog bites. The dog bite injury should be documented with photographs and diagrams when appropriate. Family physicians should educate parents and children on ways to prevent dog bites.
