Frozen Section Histoanatomy of the Peritarsal Eyelid.

Background: Mohs surgery of eyelid skin cancers requires detailed knowledge of anatomy for precise surgery and accurate evaluation of histology.

Objective: To review the histology of the peritarsal eyelid using frozen sections as encountered intraoperatively by Mohs surgeons.

Methods: The authors review the literature describing the anatomy and histology of the peritarsal eyelid from the lens of a Mohs surgeon.

Changes in inundation drive carbon dioxide and methane fluxes in a temperate wetland.

Wetlands cycle carbon by being net sinks for carbon dioxide (CO) and net sources of methane (CH). Daily and seasonal temporal patterns, dissolved oxygen (DO) availability, inundation status (flooded or dry/partially flooded), water depth, and vegetation can affect the magnitude of carbon uptake or emissions, but the extent and interactive effects of these variables on carbon gas fluxes are poorly understood. We characterized the linkages between carbon fluxes and these environmental and temporal drivers at the Old Woman Creek National Estuarine Research Reserve (OWC), OH.

Anticipated Versus Unanticipated Incomplete Mohs Micrographic Surgery for Keratinocyte Carcinomas: Impact on Treatment Delays and Final Margin Status.

Background: Mohs micrographic surgery may be discontinued with positive margins as an anticipated strategy for multidisciplinary care or as an unanticipated occurrence. Management of primary tumors has not been compared after anticipated versus unanticipated incomplete Mohs micrographic surgery (iMMS).

Objective: To compare rates and timing of adjuvant surgery after iMMS and final margin status when iMMS is anticipated versus unanticipated.

Impacts of acute and chronic suspended solids exposure on juvenile freshwater mussels.

Construction activities may affect adjacent water systems by introducing increased levels of suspended solids into the water body and may subsequently affect the survival and growth of freshwater mussels. We tested three sediment types from sites in Missouri, including Spring River sediment (SRS), Osage River bank clay soil (ORC), and quarried limestone from Columbia (LMT). We prepared series of suspensions of each sediment with total suspended solids concentrations ranging from 0 to 5000 mg/L.
