The impact of IL-6 and IL-28B gene polymorphisms on treatment outcome of chronic hepatitis C infection among intravenous drug users in Croatia.

Background: Several genes and their single nucleotide polymorphisms (SNPs) are associated with either spontaneous resolution of hepatitis C infection or better treatment-induced viral clearance. We tested a cohort of intravenous drug users (IVDU) diagnosed with chronic hepatitis C virus (HCV) for treatment response and its association with the SNPs in the interleukin-6 (rs1800795-IL6) and the interleukin-28B (rs12979860-IL28B) genes.

Methods: The study included 110 Croatian IVDU positive for anti-HCV antibody.

Expression of Ki-67 and p53 in meningiomas.

Unlabelled: Meningiomas account for about 30% of all primary brain tumors. It is difficult to predict the behaviour of meningiomas, and identification of protein markers responsible for the regulation of cell proliferation can be very helpful. The aim of this study was to evaluate immunohistochemical expression of Ki-67 and p53 in 170 meningiomas.

Polypoid angiomyofibroblastoma tumor of nasal cavity: case report.

We report an extremely rare case and localization of polypoid angiomiofibroblastoma tumour, a case report and review of the world literature concerning angiomiofibroblastoma tumour. We present the case of a 74-year-old man who underwent left anterior and posterior ethmoidectomy with extirpation of tumour mass from left nasal cavity, epipharinx and left sphenoid sinus. The prognosis for this group of tumour is good and patient didn't receive any kind of therapy except surgical treatment.

Direct molecular detection of Mycobacterium tuberculosis suspected to be the specific infection in a case of recurrent tonsillitis.

We report a case of a 21-year-old man with recurrent tonsillitis caused by Mycobacterium tuberculosis. For a period of 5 months, the patient had tonsillitis seven times and was treated with several oral or parenteral antibiotics. On one of these occasions, tonsillitis was complicated with a peritonsillar abscess that was treated by incision.
