Purpose: Non-invasive encapsulated follicular variant of papillary thyroid cancer was reclassified as non-invasive follicular thyroid neoplasm with papillary-like nuclear features (NIFTP). These neoplasms have an extremely low malignant potential. The aim of this study was (1) to assess the prevalence of NIFTP in patients with papillary thyroid carcinoma, (2) to evaluate their outcomes, and (3) to determine their molecular profile.

In patients with papillary thyroid cancer we compared clinicopathological characteristics between those harboring BRAF mutation and those without it. Twenty five consecutive patients operated for benign nodules and for papillary carcinoma were prospectively included.

A 30-bp deletion in latent membrane protein-1 gene (del-LMP-1) has been identified in various pathologies. The aim of this study was to determine EBV genotypes and 30-bp deletion frequency in HIV-infected patients from Argentina.

Design: A cross-sectional study was conducted on 172 HIV-infected individuals: 62 asymptomatic HIV carriers (group A), 30 HIV progressors (group B), 73 AIDS patients (group C), seven AIDS patients with brain lymphoma (group C-BL); and 26 blood donors (group BD) as healthy carriers. EBV load was measured in peripheral blood mononuclear cells (PBMC) and plasma samples using a semi-quantitative PCR method.
