Current management of purpura fulminans: a multicenter study.

Seven burn centers performed a 10-yr retrospective chart review of patients diagnosed with purpura fulminans. Patient demographics, etiology, presentation, medical and surgical treatment, and outcome were reviewed. A total of 70 patients were identified. Mean patient age was 13 yr. Neisseria meningitidis was the most common etiologic agent in infants and adolescents whereas Streptococcus commonly afflicted the adult population. Acute management consisted of antibiotic administration, volume resuscitation, ventilatory and inotropic support, with occasional use of corticosteroids (38%) and protein C replacement (9%). Full-thickness skin and soft-tissue necrosis was extensive, requiring skin grafting and amputations in 90% of the patients. One fourth of the patients required amputations of all extremities. Fasciotomies when performed early appeared to limit the level of amputation in 6 of 14 patients. Therefore, fasciotomies during the initial management of these patients may reduce the depth of soft-tissue involvement and the extent of amputations.

A biopsy of the use of the Baxter formula to resuscitate burns or do we do it like Charlie did it?

The Baxter formula is commonly used to calculate fluid requirements. Baxter reported that 12% of patients would require more than 4.3 mL/kg per percentage of total body surface area (%TBSA). We anecdotally observed that we frequently exceeded the predictions of the formula, and we wondered if this was unique to our practice. We studied our last 11 burn-related resuscitations and collected fluid resuscitation data from US burn centers. Twenty-eight centers were queried, and 6 centers shared data. We were therefore able to study the resuscitation data of 50 adult patients. For 29 patients (58%), 4.3 mL/kg/%TBSA was exceeded compared with the 12% reported by Baxter. These findings suggest that in actual practice, fluid volumes administered are larger than the Baxter formula predicts. This survey does not explain why. Possible reasons for the larger fluid volumes are as follows: (1) the sample is not representative; (2) the formula is used improperly; (3) burns have changed and require more fluids; (4) burn care has changed.

Problems in diagnosis and management of desmoid tumors.

Thirty-two primary desmoid tumors occurred in 29 patients. The median patient age was 32 years, and 55% of the patients were females. An antecedent history of trauma at the tumor site was elicited from 28% of patients. Thirty-one of 32 primary tumors were completely excised at initial presentation. Five tumors were treated with adjuvant radiotherapy. The overall recurrence rate for primary and recurrent lesions was 60%. The recurrence rate in children (88%) was more than twice that found in adults (38%). A single recurrence did not significantly increase the likelihood of a subsequent recurrence. Greater than 90% of all recurrences took place within 3 years of treatment. The rate of recurrence was not clearly influenced by the status of histologic margins, although this was examined in less than half the tumors. Desmoid tumors are aggressive neoplasms that exhibit a strong propensity for local recurrence. They should be treated as low-grade malignancies with documentation of histologic margins and close clinical follow-up within the framework of a tumor registry.
