Does glatiramer acetate provoke hepatitis in multiple sclerosis?

An association between multiple sclerosis and autoimmune hepatitis has been described. The latter can also be unmasked or exacerbated by a variety of therapies used in multiple sclerosis, such as beta-Interferon or glatiramer acetate. Two cases of hepatitis occurring after exposure to glatiramer acetate are described here: the first, was possibly due to autoimmune hepatitis, rather than glatiramer acetate induced liver injury, the second was definite autoimmune hepatitis.

Cell discohesion and multifocality of carcinoma in situ of the bladder: new insight from the adhesion molecule profile (e-cadherin, Ep-CAM, and MUC1).

Urothelial cell carcinoma in situ (CIS) of the bladder is a superficially diffusive and highly discohesive disease. The authors analyzed the expression of some adhesion molecules (e-cadherin and Ep-CAM) and MUC1 in 32 unifocal and multifocal bladder urothelial cell CIS in an attempt to clarify this discohesion. E-cadherin was strongly expressed, in more than 75% of the cases.

Detection of Leishmania infantum kinetoplast DNA in laryngeal tissue from an immunocompetent patient.

Mucosal leishmaniasis of the upper respiratory tract is usually associated with the visceral form or is found in immunosuppressed individuals. This report presents a case of isolated mucosal leishmaniasis in an immunocompetent patient, whose diagnosis mainly rested on histology and positive polymerase chain reaction result for Leishmania donovani in the laryngeal tissue. A 59-year-old man, who never lived outside Italy, showed a subglottic mucosal polypoid-like lesion.
