Sonography can reveal a Morton's neuroma in 85% of cases. Identification of the presumed plantar digital nerve in continuity with the mass improves diagnostic confidence. The finding of an interdigital mass greater than 20 mm in length should raise suspicion of an abnormality other than a neuroma.

Cefoxitin, a parenteral cephamycin ,B-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 were bacteremic. The most frequently recovered pathogens were Staphylococcus aureus (six patients), Haemophilus influenzae (four patients), and Streptococcus pneumoniae (three patients). All organisms were susceptible to cefoxitin. All 26 children were considered improved or cured. No severe adverse reactions were encountered. Phlebitis (4%), eosinophilia (12%), and elevated liver function tests (4%) were associated with therapy. Cefoxitin appears to be a safe, effective, and welltolerated antibiotic when used in children with susceptible bacterial infections other than meningitis.Cefoxitin, a cephamycin, beta-lactam antibiotic, has been effective and well tolerated in adults with infections due to susceptible bacteria (3-5). Its antimicrobial spectrum of activity, which includes gram-positive cocci and Haemophilus influenzae, makes it a potentially useful drug for the parenteral treatment of serious infections in children, which are most often due to these organisms (2).
