Fulminant immune-related colitis after dual checkpoint inhibitor therapy: case report.

Immune-related (IR) colitis is a potentially life-threatening complication of checkpoint inhibitors. Its presentation often includes diarrhea, abdominal pain and rectal bleeding and the median time to onset is 6-10 weeks post initiation of immunotherapy. We report an unusual case of fulminant IR-colitis beginning 3 days after the first dose of dual checkpoint blockade.

Utility of hemoglobin electrophoresis to distinguish between severe delayed hemolytic transfusion reaction versus hyperhemolysis syndrome.

Delayed hemolytic transfusion reaction (DHTR) and hyperhemolysis syndrome (HHS) are both complications of red blood cell transfusions in patients with sickle cell disease.Clinically, both present with hemolysis and can be difficult to differentiate. Hemoglobin electrophoresis may aid in the diagnosis.

A case of viral meningitis due to Varicella Zoster virus infection in a young adult male.

A 36-year-old male with headaches was empirically treated for herpes simplex virus meningitis; CSF PCR testing later confirmed varicella zoster virus meningitis. Valacyclovir was increased to 2 g QID for remaining duration of therapy with full recovery. This case highlights the importance of comprehensive testing and proper treatment adjustment for rarer etiologies of aseptic meningitis.

Platinum-Catalyzed Hydrosilylation in Polymer Chemistry.

This paper addresses a review of platinum-based hydrosilylation catalysts. The main field of application of these catalysts is the curing of silicone polymers. Since the 1960s, this area has developed rapidly in connection with the emergence of new polymer compositions and new areas of application.
