Leclercia Adecarboxylata Causing Necrotizing Fasciitis in an Immunocompetent Athlete Injecting Illicit Testosterone Supplements.

Leclercia adecarboxylata (L. adecarboxylata) is an uncommon and often misdiagnosed cause of multiple infection types including skin and soft tissue, cholecystitis, and septicemia. It commonly afflicts immunocompromised hosts or individuals who experience trauma in aquatic environments. We present a case where this bacteria causes necrotizing fasciitis as a consequence of injecting street bought testosterone supplements. This patient was treated successfully with excisional debridement of the wound as well as a one week course of Linezolid and Bactrim.

Androgen receptor activation: a prospective therapeutic target for bladder cancer?

INTRODUCTION: Patients with non-muscle-invasive or muscle-invasive bladder cancer undergoing surgery and currently available conventional therapy remain having a high risk of tumor recurrence or progression, respectively. Novel targeted molecular therapy is therefore expected to improve patient outcomes. Meanwhile, substantially higher incidence of bladder cancer in men has prompted research on androgen-mediated androgen receptor (AR) signaling in this malignancy. Indeed, preclinical evidence has suggested that AR signaling plays an important role in urothelial carcinogenesis and tumor outgrowth as well as resistance to some of the currently available conventional non-surgical therapies. Areas covered: We summarize and discuss available data suggesting the involvement of AR and its potential downstream targets in the development and progression of bladder cancer. Associations between AR signaling and sensitivity to cisplatin/doxorubicin or bacillus Calmette-Guérin treatment are also reviewed. Expert opinion: AR activation is likely to correlate with the promotion of urothelial carcinogenesis and cancer outgrowth as well as resistance to conventional therapies. Molecular therapy targeting the AR may thus provide effective chemopreventive and therapeutic approaches for urothelial cancer. Accordingly, bladder cancer can now be considered as an endocrine-related neoplasm. Clinical application of various anti-AR therapies available for AR-dependent prostate cancer to bladder cancer patients is anticipated.
