Studies have indicated that the appendix plays an evident role in immune response and harbors a biofilm that may remain unaffected by gastrointestinal infections, such as infection with Clostridium difficile. Our research analyzes the prominent gut-associated lymphoid tissue (GALT) as a mechanism of defence in infection, as well as the robust biofilm that could aid in the reinoculation of beneficial bacteria within the colon. Furthermore, we wanted to determine if patients who have undergone a prior appendectomy, leading to decreased GALT and a lack of a bacterial reservoir, were predisposed to the development of Clostridium difficile, with particular emphasis in the recurrence and development of fulminant Clostridium difficile infections. Although research continues to be conflicting, there appears to be some connection between these variables, but prospective studies are needed in order to say for certain that there is a link.Hemophagocytic lymphohistiocytosis (HLH) is a rare hematologic disease caused by a disordered immune system. We present a case of reactive HLH (RHLH) with uncommon skin findings in a 35-year-old African American female with a history of hidradenitis suppurativa and morbid obesity. Skin findings on physical exam revealed bullous, ecchymotic, hypopigmented, and ulcerated lesions. The literature on the cutaneous lesions of RHLH is limited. Skin findings are an underrecognized feature of RHLH and can help alert to its presence or its recurrence after treatment.An enzymatic crosslinking strategy using hydrogen peroxide (H2O2) and horseradish peroxidase (HRP) has been receiving increasing attention for use with in situ-formed hydrogels (IFHs). Several studies have reported the application of IFHs in cell deliver
