Life-threatening altered mental status secondary to memantine in an adolescent undergoing cranial radiotherapy for medulloblastoma.

Introduction: Memantine is used for neurocognitive protection in patients undergoing cranial radiotherapy for central nervous system tumors and is reported to be well-tolerated.

Case Report: Presented is a case of memantine-induced altered mental status requiring an intensive care unit admission. An 18-year-old male with relapsed, progressive medulloblastoma presented with severe altered mental status shortly after the first fraction of palliative whole brain radiotherapy.

Guideline for Children With Cancer Receiving General Anesthesia for Procedures and Imaging.

Children with cancer and those undergoing hematopoietic stem cell transplantation frequently require anesthesia for imaging as well as diagnostic and therapeutic procedures from diagnosis through follow-up. Due to their underlying disease and side effects of chemotherapy and radiation, they are at risk for complications during this time, yet no published guideline exists for preanesthesia preparation. A comprehensive literature review served as the basis for discussions among our multidisciplinary panel of oncologists, anesthesiologists, nurse practitioners, clinical pharmacists, pediatric psychologists, surgeons and child life specialists at the Children's Hospital of Philadelphia.

Improving Guideline-Congruent Care for Chemotherapy-Induced Nausea and Vomiting Prophylaxis in Pediatric Oncology Patients.

Purpose: Chemotherapy-induced nausea and vomiting (CINV) is a very common side effect of pediatric cancer therapy. High-quality, evidence-based, pediatric-specific guidelines for prophylaxis and treatment of CINV are available. At many centers, guideline-concordant care is uncommon.

A nanoscale DNA force spectrometer capable of applying tension and compression on biomolecules.

Single molecule force spectroscopy is a powerful approach to probe the structure, conformational changes, and kinetic properties of biological and synthetic macromolecules. However, common approaches to apply forces to biomolecules require expensive and cumbersome equipment and relatively large probes such as beads or cantilevers, which limits their use for many environments and makes integrating with other methods challenging. Furthermore, existing methods have key limitations such as an inability to apply compressive forces on single molecules.
