Therapeutic efficacy of an Fc-enhanced TCR-like antibody to the intracellular WT1 oncoprotein.

Purpose: RMFPNAPYL (RMF), a Wilms' tumor gene 1 (WT1)-derived CD8 T-cell epitope presented by HLA-A*02:01, is a validated target for T-cell-based immunotherapy. We previously reported ESK1, a high avidity (Kd < 0.2 nmol/L), fully-human monoclonal antibody (mAb) specific for the WT1 RMF peptide/HLA-A*02:01 complex, which selectively bound and killed WT1(+) and HLA-A*02:01(+) leukemia and solid tumor cell lines.

The HoVert technique: a novel method for the sectioning of alopecia biopsies.

Background: Cicatricial forms of alopecia, including lichen planopilaris (LPP) and discoid lupus erythematosus (DLE), may present with overlapping clinical features. In such cases, histopathological examination may provide key information for resolving the differential diagnosis. Optimally, microscopical analysis for alopecia requires both vertical and horizontal sections, and this may necessitate multiple samples.

Left atrial fibroelastoma.

We describe a 67-year-old man with a history of stroke who was found to have a mass at the left atrial ridge, at the free wall of the left atrium between the left atrial appendage and the pulmonary vein. The mass was removed surgically and pathological analysis showed fibroelastoma. A literature search showed that fibroelastoma in the left atrial ridge frequently causes embolic stroke.

The use of somatosensory evoked potentials to determine the relationship between patient positioning and impending upper extremity nerve injury during spine surgery: a retrospective analysis.

Somatosensory evoked potential (SSEP) monitoring is used to prevent nerve damage in spine surgery and to detect changes in upper extremity nerve function. Upper extremity SSEP conduction changes may indicate impending nerve injury. We investigated the effect of operative positioning on upper extremity nerve function retrospectively in 1000 consecutive spine surgeries that used SSEP monitoring.
