Wire-localized breast biopsy (WLBB) remains the standard method for the surgical excision of nonpalpable breast lesions. Because of many of its shortcomings, most important a high microscopic positive margin rate, alternative approaches have been described, including radioactive seed localization (RSL). This review highlights the literature regarding RSL, including safety, the ease of the procedure, billing, and oncologic outcomes. ⋯ RSL is a promising approach for the resection of nonpalpable breast lesions. It is a reliable and safe alternative to WLBB. RSL is at least equivalent compared with WLBB in terms of the ease of the procedure, removing the target lesion, the volume of breast tissue excised, obtaining negative margins, avoiding a second operative intervention, and allowing for simultaneous axillary staging.

Comparative Study
Sustained low-efficiency dialysis versus continuous veno-venous hemofiltration for postsurgical acute renal failure.
In postsurgical acute renal failure patients with moderate unstable hemodynamics or fluid overload, the choice of dialysis modality is difficult. This study was performed to compare the outcomes between the sustained low-efficiency dialysis (SLED) and continuous veno-venous hemofiltration (CVVH) in these patients. ⋯ Among the postsurgical patients requiring acute dialysis with severe fluid overload or moderately unstable hemodynamics, the patients treated with SLED had a higher first postdialysis MAP than those treated with CVVH, which led to lower mortality. Further multicenter randomized clinical trials of larger sample size are needed to compare the effects of SLED and CVVH on the outcomes of postsurgical acute dialysis patients.

Patients with penetrating injuries are known to have worse outcomes than those with blunt trauma. We hypothesize that within each injury mechanism there should be no outcome difference between insured and uninsured patients. ⋯ Insurance status is a potent predictor of outcome in both penetrating and blunt trauma.
