Items in AFP with MESH term: Wound Infection
ABSTRACT: Vibrio vulnificus infection is the leading cause of death related to seafood consumption in the United States. This virulent, gram-negative bacterium causes two distinct syndromes. The first is an overwhelming primary septicemia caused by consuming raw or undercooked seafood, particularly raw oysters. The second is a necrotizing wound infection acquired when an open wound is exposed to warm seawater with high concentrations of V. vulnificus. Most patients, including those with primary infection, develop sepsis and severe cellulitis with rapid development to ecchymoses and bullae. In severe cases, necrotizing fasciitis can develop. Case-fatality rates are greater than 50 percent for primary septicemia and about 15 percent for wound infections. Treatment of V vulnificus infection includes antibiotics, aggressive wound therapy, and supportive care. Most patients who acquire the infection have at least one predisposing immunocompromising condition. Physician awareness of risk factors for V. vulnificus infection combined with prompt diagnosis and treatment can significantly improve patient outcomes. (Am Fam Physic
Skin and Wound Infections: An Overview - Article
ABSTRACT: Skin infections are common and may be caused by bacteria, fungi or viruses. Breaks in the skin integrity, particularly those that inoculate pathogens into the dermis, frequently cause or exacerbate skin infections. Bacterial skin infections caused by corynebacteria include erythrasma, trichomycosis axillaris and pitted keratolysis. Staphylococci may cause impetigo, ecthyma and folliculitis. Streptococcal skin infections include impetigo and erysipelas. Human papillomavirus skin infections present as several different types of warts, depending on the surface infected and its relative moisture, and the patterns of pressure. The many dermatomycoses (skin infections caused by fungi or yeasts) include tinea capitis, tinea barbae, tinea cruris, tinea manus, tinea pedis and tinea unguium (onychomycosis). Candidal infections occur in moist areas, such as the vulva, mouth, penis, skinfolds and diaper area. Wounds caused by wood splinters or thorns may result in sporotrichosis. Animal bites may result in complex, serious infections, requiring tetanus and, possibly, rabies prophylaxis in addition to appropriate antibiotic therapy.
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.
