Oral manifestations of inflammatory bowel disease.

Inflammatory bowel diseases (IBD), including Crohn's disease and ulcerative colitis, have important extraintestinal manifestations, notably in the oral cavity. These oral manifestations can constitute important clinical clues in the diagnosis and management of IBD, and include changes at the immune and bacterial levels. Aphthous ulcers, pyostomatitis vegetans, cobblestoning and gingivitis are important oral findings frequently observed in IBD patients. Their presentations vary considerably and might be well diagnosed and distinguished from other oral lesions. Infections, drug side effects, deficiencies in some nutrients and many other diseases involved with oral manifestations should also be taken into account. This article discusses the most recent findings on the oral manifestations of IBD with a focus on bacterial modulations and immune changes. It also includes an overview on options for management of the oral lesions of IBD.

Unusual presentation of Ramsay Hunt syndrome in renal transplant patients: case report and literature review.

Ramsay Hunt syndrome (RHS) is a rare manifestation of varicella zoster virus (VZV) infection that accounts for around 12% of all cases of facial paralysis. Although it is more common in immunosuppressed individuals, it has not been yet reported in kidney transplant recipients. We describe the case of a 41-year-old man with a history of renal transplant for whom the diagnosis and treatment of RHS were delayed owing to an unusual presentation. We also review the literature on VZV infection in renal transplant patients.
