Among the most common causes of infection outside health-care institutions, community-acquired methicillin-resistant Staphylococcus aureus (Community aquired-MRSA) most often affects the skin and soft tissues. Besides causing significant morbidity, community-aquired MRSA is increasingly associated with serious and often fatal necrotizing pneumonia or fasciitis, endocarditis, and sepsis. The authoritative links on this resource help you to keep up to date with new diagnostic tests and treatments for community-aquired MRSA, as well as the latest news about local outbreaks and infection control strategies.
A15-year-old girl was referred to a pediatric endocrinologist for evaluation of hyperthyroidism. Her primary concerns were intermittent increases in heart rate and appetite (with a weight gain of 7 kg within the past year), feeling hot at night even in winter, persistent lower extremity edema that had been present since age 4 years, and difficulty in concentrating. She denied having diarrhea, sweating, fatigue, breathing difficulties, hair loss, or changes in hair texture.
For 3 days, a 7-year-old girl had severe, generalized abdominal pain. The patient described the pain as sharp and achy without radiation; she denied any relieving or aggravating factors. She also reported decreased appetite and energy for the past week.
The rash on this 4-week-old girl had appeared 5 days earlier on her face as thickened scales on an erythematous base and subsequently spread to the scalp, shoulder, chest, abdomen, and extremities. A few bullae were noted on the neck and hands. Initial treatment with cephalexin failed to control the rash, and the infant was admitted to the hospital for further evaluation.

Septic arthritis and several other types of musculoskeletal infections in children are caused by group A Streptococcus. Methicillin-resistant Staphylococcus aureus is emerging as a cause of skin infections in the sports community. Neisseria meningitidis in purpura fulminans usually is not associated with direct infection of musculoskeletal structures. More »
A novel H1N1 influenza virus has emerged from swine and is causing a worldwide pandemic. Children and young adults have been most affected, in terms of both numbers of cases and severity of disease. Perhaps the most striking feature of the pandemic so far is that fewer than half of those hospitalized or killed by this virus have had identifiable prior medical conditions or risk factors. More »
THAT BLUE LIGHT KILLS methicillin-resistant Staphylococcus aureus (MRSA) was demonstrated in the article “Visible 405 nm SLD Light Photo-Destroys Methicillin-Resistant Staphylococcus aureus (MRSA) In Vitro,” in the December 2008 issue of Lasers in Surgery and Medicine. Concerns about the clinical safety of the wavelength used (405 nm, spectral width 390 to 420 nm), which contains traces of ultraviolet light, led Chukuka Enwemeka, PhD, and colleagues from the School of Health Professions,...

Health care–associated pneumonia (HCAP) is a relatively new term used to describe pneumonia that develops in patients who have recently been exposed to nosocomial and drug-resistant pathogens as a result of hospitalization or residence in a nursing home, for example. A recent study found that about 25% of patients hospitalized with pneumonia had HCAP, and that the mortality rate was higher in those with HCAP than in those with community-acquired pneumonia (CAP).

I advise my patients who are carriers of methicillin-resistant Staphylococcus aureus (MRSA) to keep their fingernails trimmed. Long nails make the subungual spaces good havens for bacteria. S aureus, including MRSA, has been isolated from the subungual spaces of the hands of many at-risk patients who are MRSA carriers More »
Tenofovir disoproxil fumarate is a nucleotide reverse transcriptase inhibitor that is usually well tolerated with few adverse effects, but it has been implicated in the development of Fanconi syndrome and renal insufficiency because of its effects on the proximal renal tubule. Vancomycin nephrotoxicity is infrequent but may result from coadministration with other nephrotoxic agents, such as aminoglycosides. We report the cases of 2 patients receiving tenofovir as part of an antiretroviral... More »
