Fine needle aspiration cytology of polymorphous adenocarcinoma of the salivary glands: A report of 11 patients and review of the literature.

Background: Polymorphous adenocarcinoma (PAC) is a rare malignant tumor of the minor salivary glands. It has an infiltrative growth, variable architectural patterns, neurotropism and cellular monomorphism. Approximately 75% of the cases show a specific mutation in the protein kinase D1 (PRKD1) gene.

Prevalence of Fecal Incontinence in Women During Pregnancy: A Large Cross-Sectional Study.

Background: Although some studies have analyzed the prevalence of urinary incontinence during pregnancy, there are scarce data on the frequency and characteristics of fecal incontinence during this period.

Objective: The aim of this study was to determine the incidence and characteristics of women with fecal incontinence symptoms during early and late pregnancy, to evaluate its impact on quality of life, and to identify whether there is a specific clinical pattern that could identify patients at risk.

Design: This was a cross-sectional observational study.

Time-dependent effects of unfractionated heparin in patients with ST-elevation myocardial infarction transferred for primary angioplasty.

Aims: Initial thrombolysis in myocardial infarction (TIMI) flow and mortality are related in ST-elevation myocardial infarction (STEMI) patients treated with primary angioplasty (PPCI). It is unclear whether early adjunctive treatment with unfractionated heparin (UFH) is beneficial for coronary patency. We investigated the effect of UFH administered before transfer versus in the catheterization laboratory (CathLab) on initial patency of the infarct related artery (IRA) in transferred STEMI patients treated with PPCI.

Prevalence of abnormal anal cytology and high-grade squamous intraepithelial lesions among a cohort of HIV-infected men who have sex with men.

Background: The incidence of anal cancer among HIV-infected patients is higher than that in other populations. Anal high-grade squamous intraepithelial lesions are considered precursors to invasive squamous-cell carcinomas and are strongly associated to high-risk human papillomavirus infection.

Objective: The aim of this study is to determine the prevalence of anal high-grade squamous intraepithelial lesions through screening based on cytology and high-resolution anoscopy with biopsy in a cohort of HIV-infected men who have sex with men.

Micropapillary carcinoma of the urinary tract: a cytologic study of urine and fine-needle aspirate samples.

Objective: Micropapillary carcinoma (MPC) is an aggressive variant of urothelial carcinoma that needs early and specific recognition. In order to determine whether this tumor variant can be recognized with cytology, we evaluated a large cytohistological series.

Study Design: It was a retrospective cytohistological correlation study including 20 patients with MPC.
