Upper and lower respiratory infections are encountered commonly in the emergency department. Visits resulting from occurrences of respiratory disease account for 10% of all pediatric emergency department visits and 20% of all pediatric hospital admissions. Causes of upper airway infections include croup, epiglottitis, retropharyngeal abscess, cellulitis, pharyngitis, and peritonsillar abscesses...

A 4-year-old girl with a history of surgery for strabismus was assessed in the emergency department for pruritic lesions on the right leg that had appeared 3 days previously. Although the patient was afebrile and in good general health, she was diagnosed with bacterial cellulitis and admitted to the hospital for intravenous antibiotic therapy. Improvement was very slow and the patient required ...

The febrile young infant is commonly encountered in the emergency department, and the incidence of serious bacterial infection in these patients is as high as 15%. Undiagnosed bacterial infections such as meningitis and bacteremia can lead to overwhelming sepsis and death or neurologic sequelae. Undetected urinary tract infection can lead to pyelonephritis and renal scarring. These outcomes nec...

Necrotizing fasciitis is a rapidly progressive life threatening bacterial infection of the skin, the subcutaneous tissue, and the fascia. We present a case of necrotizing fasciitis involving the nose complicated by cavernous sinus thrombosis. Few cases of septic cavernous sinus thrombosis have been reported to be caused by cellulitis of the face but necrotizing fasciitis of the nose is rare. It...

The composition of human skin acts as a natural habitat for various bacterial species that function in a commensal and symbiotic fashion. In a healthy individual, bacterial flora serves to protect the host. Under certain conditions such as minor trauma, impaired host immunity, or environmental factors, the risk of developing skin infections is increased. Although a large majority of bacterial a...

In this study, we compared Escherichia coli isolates from chickens with avian cellulitis with those from feces of healthy chickens. Cellulitis-derived strains presented phenotypic and genotypic characteristics of greater virulence than did the fecal isolates. Phylogenetic analysis by repetitive extragenic palindromic-PCR showed that, in agreement with their virulence characteristics, the cellul...

Fusidic acid (CEM-102), an orally bioavailable fusidane antibiotic with a unique mode of action, is under development for treatment of acute gram-positive bacterial skin and skin structure infections, including those caused by methicillin-susceptible and methicillin-resistant Staphylococcus aureus and streptococci. A phase 2, adaptive design, randomized, double-blind, multiple-center study of 1...

Cefoxitin, a parenteral cephamycin beta-lactam antibiotic, was evaluated for safety and efficacy in children with bacterial infections other than meningitis. Twentysix patients between 3 months and 7 years of age were treated with 80 to 160 mg/kg per day. The most common diagnoses were cellulitis (13 patients), pneumonia (5 patients), and bone and joint infection (4 patients). Nine patients wer...

Dissecting cellulitis is an inflammatory disease of the skin. We report a case of recurrent dissecting cellulitis in a patient with Crohn's disease. A 31-year-old man with a history of purulent scalp lesions presented with night sweats, weight loss, abdominal pain, and hematochezia. Colonoscopy revealed a diffuse friable mucosa with extensive pseudopolyps. Scalp biopsy demonstrated epidermoid i...

purpose: to report a case of acute myelogenous leukemia (aml) presenting with periorbital cellulitis and progressing to facial and neck cellulitis. case report: a 17 year old male patient presented with periorbital cellulitis which progressed to the right hemifacial and neck area. he did not respond to regular antibiotic therapy. peripheral blood smear showed leukocytosis with predominance of i...
