Objective To determine the outcomes effect of changing trends in patients with necrotizing acute soft tissue infections (NASTI) 2000–2008. Methods A single institution retrospective chart review of all patients treated for NASTI. Results There were 393 patients with mean age 50 years, diabetes 53%, % body surface area excised 3.5. Wounds were located on: extremity 57%, perineum 40%, trunk 26%. Wound cultures %: polymicrobial=62, Staphylococci=48, Streptococci=31. Patients developing complications %: Pulmonary=23, renal insufficiency/failure=27. During the study period, overall mortality rate remained unchanged: 30/393=7.6% (5.5% for patients first admitted by burn/trauma/acute care surgery vs. 29% for all other services, p =0.003). Significant annual increases were found in number of patients, p =0.03, male sex, p =0.000, transfer from outside hospital, p p =0.003, ventilator requirement >24h, p =0.0005, APACHE II p =0.002, and number of patients developing any complication, p =0.04. Statistically significant decreases annually were found in: days of antibiotic use, p =0.008, number of operations required for excision, p =0.02, development of non-wound infections, p =0.002, and length of stay in days (LOS), p =0.03. Conclusions This is the largest cohort of NASTI patients from a single institution to date, demonstrating significantly shorter LOS and decreased non-wound infection rates in the face of increasing BMI and APACHE II scores. The increasing number of patients and BMI suggests a causal relationship between NASTI and obesity. Initial care by surgeons experienced in caring for these patients provides mortality rates well below the national average.

Due to a successful Haemophilus Influenzae (HIF) vaccination program, this pathogen is no longer a major contributor to childhood morbidity and mortality. The effect on adult acquisition of HIF is unknown. The purpose of this study was to determine HIF infection frequency in severely burned patients. In a 62-month period, there were 1486 admissions. Twenty-four of 1486 (1.6%) burn patients had HIF pneumonia: 16 (1%) within 72 h after injury; 8 (0.5%) patients developed it after the seventh day of hospitalization; 74 of 1486 (5.0%) burn patients had pneumonia due to other organisms. There was no statistically significant difference between patients with HIF pneumonia and those with other pathogens with respect to age, race, sex, percent total body surface area (TBSA), inhalation injury, ventilator days, intensive care days, sepsis, or mortality. Nineteen percent of patients with HIF were

Infrequently reported, serious allergic reactions to topical antimicrobial agents used in the treatment of burn injuries are a potential source of confusion. To avoid misdirected therapy, an understanding of the manifestations of such reactions is important. Two recent cases of serious allergic reactions, one to silver sulphadiazine, one to mafenide acetate, are presented and the literature is reviewed.
