Treatment-Refractory Scleredema Diabeticorum Managed With Re-irradiation Using Volumetric Modulated Arc Therapy.

Scleredema diabeticorum is a rare connective tissue complication of diabetes, most typically observed in adults with longstanding type 2 diabetes. Patients develop reticular dermis thickening with a peau d'orange appearance at the upper back and neck that occasionally extends over the deltoids and lower back. While considered a benign disorder, it may signify more significant diabetes and can be functionally and cosmetically impairing with insidious onset, few to no effective treatments, and low spontaneous remission potential.

Proton Therapy in the Treatment of Men with Breast Cancer.

Purpose: Male breast cancer treatment involves multimodality therapy, including radiation therapy; nevertheless, few men have received proton therapy (PT) for it. Further, heart disease is an established leading cause of death in men, and radiation therapy heart dose correlates with cardiac toxicity, highlighting the need for cardiac-sparing radiation techniques. Thus, we provide a descriptive analysis of PT in a male breast cancer cohort.

Impact of mandated drug monitoring on opioid use during highly conformal radiotherapy for oropharynx cancer.

Background: Prescription drug monitoring programs (PDMPs) have proliferated due to increasing opioid-related deaths. We evaluated acute opioid use changes for 64 patients treated with highly conformal radiotherapy (RT) following a state-mandated PDMP.

Methods: Patients receiving proton therapy (PT) (n=40), intensity-modulated RT (IMRT) (n=14), or both (n=10) were divided into preintervention (n=26) and postintervention cohorts (n=38); records were reviewed retrospectively under an institutional review board (IRB)-approved tracking protocol.

Supramolecular Click Chemistry for Surface Modification of Quantum Dots Mediated by Cucurbit[7]uril.

Cucurbiturils (CBs), barrel-shaped macrocyclic molecules, are capable of self-assembling at the surface of nanomaterials in their native state, via their carbonyl-ringed portals. However, the symmetrical two-portal structure typically leads to aggregated nanomaterials. We demonstrate that fluorescent quantum dot (QD) aggregates linked with CBs can be broken-up, retaining CBs adsorbed at their surface, via inclusion of guests in the CB cavity.

Radiation Treatment for Cancer of the Anal Margin.

Objective: To identify best treatment practices by examining outcomes of anal margin cancer patients treated with radiotherapy.

Methods: Relevant literature was compared with 38 patients at our institution treated 1979 to 2019 with curative radiotherapy. Median age was 51.
