RESUMEN

Breast implant anaplastic large cell lymphoma (ALCL) is a T-cell neoplasm arising around textured breast implants that was recognized recently as a distinct entity by the World Health Organization. Rarely, other types of lymphoma have been reported in patients with breast implants, raising the possibility of a pathogenetic relationship between breast implants and other types of lymphoma. We report eight cases of Epstein-Barr virus (EBV)-positive large B-cell lymphoma associated with breast implants. One of these cases was invasive, and the other seven neoplasms were noninvasive and showed morphologic overlap with breast implant ALCL. All eight cases expressed B-cell markers, had a non-germinal center B-cell immunophenotype, and were EBV+ with a latency type III pattern of infection. We compared the noninvasive EBV+ large B-cell lymphoma cases with a cohort of breast implant ALCL cases matched for clinical and pathologic stage. The EBV+ large B-cell lymphoma cases more frequently showed a thicker capsule, and more often were associated with calcification and prominent lymphoid aggregates outside of the capsule. The EBV+ B-cell lymphoma cells were more often arranged within necrotic fibrinoid material in a layered pattern. We believe that this case series highlights many morphologic similarities between EBV+ large B-cell lymphoma and breast implant ALCL. The data presented suggest a pathogenetic role for breast implants (as well as EBV) in the pathogenesis of EBV+ large B-cell lymphoma. We also provide some histologic findings useful for distinguishing EBV+ large B-cell lymphoma from breast implant ALCL in this clinical setting.

RESUMEN

The American Society of Plastic Surgeons commissioned a multistakeholder Work Group to develop recommendations for autologous breast reconstruction with abdominal flaps. A systematic literature review was performed and a stringent appraisal process was used to rate the quality of relevant scientific research. The Work Group assigned to draft this guideline was unable to find evidence of superiority of one technique over the other (deep inferior epigastric perforator versus pedicled transverse rectus abdominis musculocutaneous flap) in autologous tissue reconstruction of the breast after mastectomy. Presently, based on the evidence reported here, the Work Group recommends that surgeons contemplating breast reconstruction on their next patient consider the following: the patient's preferences and risk factors, the setting in which the surgeon works (academic versus community practice), resources available, the evidence shown in this guideline, and, equally important, the surgeon's technical expertise. Although theoretical superiority of one technique may exist, this remains to be reported in the literature, and future methodologically robust studies are needed.

RESUMEN

The purpose of this study was to examine the hospital course and outcomes of elderly trauma patients. We accomplished a retrospective review of all consecutive trauma patients admitted to a level II trauma center from January 2000 to April 2002. Gender, Injury Severity Score (ISS), length of stay (LOS), operative procedure, morbidity, and mortality of patients > or = 90 years of age were compared with younger patients. Of 2645 trauma admissions, 137 patients (5%) were > or = 90 years (range, 90 to 108 years; mean, 93.1 years); 5 patients were > or = 100 years. One hundred eleven (81%) patients were female; 26 (19%) male. Average ISS for patients > or = 90 was 8.75 and was 7.78 for younger patients. One hundred sixteen elderly patients (85%) had ISS < 15. Falls were the most common mechanism of injury (93%), usually ground-level falls (64%). Two hundred ninety-two injuries included 133 fractures and 102 soft tissue injuries. Thirty-four elderly patients (25%) and 733 younger patients (29%) required surgery. Complications developed in 8 per cent of older and 6 per cent of younger patients. Hospital LOS averaged 4.36 days for older and 3.51 days for younger patients. Six older (4.4%) and 63 younger (2.5%) patients died. ISS scores and LOS were slightly higher in elderly patients, but morbidity and mortality were comparable in both groups.
