The human leukocyte antigen G molecule (HLA-G) expression in patients with nasal polyposis.

Introduction: Sinonasal polyposis (NP) is a chronic inflammatory pathology of the nasal/paranasal cavities which affects from 1%-4% of the population. Although polyps seem to be a manifestation of chronic inflammation in both allergic and non-allergic subjects, the pathogenesis of nasal polyposis remains unknown. HLA-G molecules are a kind of no classic class I antigen with anti-inflammatory and tolerogenic properties.

Hybrid capture II and PapilloCheck® tests for detection of anal high-risk human papillomavirus.

Introduction: This study evaluated the level of concordance between hybrid capture II (HCII) and PapilloCheck® for the detection of high-risk human papillomavirus (HPV) in anal samples.

Methods: Anal cell samples collected from 42 human immunodeficiency virus (HIV)+ patients were analyzed.

Results: Considering only the 13 high-risk HPV types that are detectable by both tests, HCII was positive for 52.

Analysis of HLA-G gene polymorphism and protein expression in invasive breast ductal carcinoma.

The human leukocyte antigen G (HLA-G) is a non-classical HLA class I molecule predominantly expressed in trophoblastic placental cells to protect the fetus during pregnancy. However, evidence has shown that this molecule may be implicated in the immune escape mechanism of tumor cells. Thus, the aim of this study was to evaluate the frequency of 14-bp insertion/deletion HLA-G polymorphism, as well as the expression of this molecule in patients with invasive breast ductal carcinoma (IDC).

A comparative study between conventional and liquid-based cytology in screening for anal intraepithelial lesions in HIV-positive patients.

Anal intraepithelial neoplasia (AIN) is associated with HPV infection and can be detected by cytological screening. While conventional exfoliative cytology (CC) is a low-cost and nonaggressive method, liquid-based cytology (LBC) tends to give clearer readings. Although studies of the efficacy of anal cancer screening methods would be of great importance for groups at high risk for AIN, few such studies have been conducted.

Value of human papillomavirus typing for detection of anal cytological abnormalities.

Purpose: The objective of this study was to evaluate anal cytology and human papillomavirus (HPV) typing in patients with human immunodeficiency virus infection.

Materials And Methods: Anal samples were collected from 61 patients (44 men and 17 women) and analyzed by PapilloCheck test and conventional cytology.

Results: Of all anal samples, 37.

Rhinoscleroma causing severe bilateral nasal obstruction.

Rhinoscleroma is a chronic, infectious and granulomatous disease of the respiratory tract. There is often a delay in diagnosis due to unfamiliarity with the disease and also because culture is not always positive. We report a case in a 26-year-old woman with granular mass obstructing bilateral nasal cavities and causing breathing difficulty.
