The results of 20 patients were included in the analysis. A paired-samples t-test revealed no significant difference between clinical and ultrasound widths (t=-1.324, p=.20). Similarly, there was no significant difference between the lengths found from clinical assessment and ultrasound (t=-1.093, p=.29). For different tumor types, there was no significant difference between clinical and ultrasound widths or lengths for basal cell carcinoma (t=-1.307, p=.23; t=-1.389, p=.20) or squamous cell cancer (t=-0.342, p=.73; t=0.427, p=.68). CONCLUSION There is a diagnostic role for high-resolution ultrasound in Mohs surgery regarding the delineation of surgical margins, but its limitations preclude its practical adoption at this time.

CaHA, a new, easily injectable, safe dermal filler, has emerged as an excellent option for soft tissue augmentation in aging hands.

Background: Bar coding can reduce hospital pharmacy dispensing errors, but it is unclear if the benefits of this technology justify its costs. The purpose of this study was to assess the costs and benefits and determine the return on investment at the institutional level for implementing a pharmacy bar code system. Methods: We performed a cost-benefit analysis of a bar code-assisted medication-dispensing system within a large, academic, nonprofit tertiary care hospital pharmacy. We took the implementing hospital's perspective for a 5-year horizon. The primary outcome was the net financial cost and benefit after 5 years. The secondary outcome was the time until total benefits equaled total costs. Single-variable, 2-variable, and multiple-variable Monte Carlo sensitivity analyses were performed to test the stability of the outcomes.
