BACKGROUND Fournier gangrene due to advanced rectal cancer is a rapidly progressive gangrene of the perineum and buttocks. Emergency surgical debridement of necrotic tissue is crucial, and secondary surgery to resect tumors is necessary for wound healing. However, pelvic exenteration damages the pelvic floor, increasing the likelihood of herniation of internal organs into the infectious wound. ...

BACKGROUND Even though there is no consensus, many authors believe that in the cases of large hiatal defects, structurally altered crura and/or absence of peritoneal lining, a crural reinforcement should be performed. Reinforcement could be performed with different techniques and different type of mesh, either synthetic or biologic. The disadvantages of mesh repair include the possibility of se...

We give an overview of relative tensor products (RTPs) for von Neumann algebra modules. For background, we start with the categorical definition and go on to examine its algebraic formulation, which is applied to Morita equivalence and index. Then we consider the analytic construction, with particular emphasis on explaining why the RTP is not generally defined for every pair of vectors. We also...

OBJECTIVE To present our method for anterior skull base reconstruction after oncological resections. METHODS One hundred nine patients who had undergone 120 anterior skull base resections of tumors (52 malignant [43%], 68 benign [57%]) via the subcranial approach were studied. Limited dural defects were closed primarily or reconstructed using a temporalis fascia. Large anterior skull base def...

Whereas arthroscopic superior capsule reconstruction has recently been introduced to treat irreparable rotator cuff tears with encouraging outcomes, graft options and fixation remain debated. The purpose of this article is introduce a modified technique using the long head biceps tendon as augmentation for fascia lata autograft.

A rare case of extensive lesions of secondary syphilis of varied morphology is presented. The predominant lesions were of conyloma lata, which were present on neck, axillae, inguinal folds, and inner thighs.
