von Hansemann Cells from Fresh Urine Sediment Samples in the Diagnosis of Malakoplakia.

Background: Malakoplakia is characterized by the presence of plaques with macrophages containing inclusion bodies. The diagnosis of this disease is carried out by biopsy of the lesion. The objective of this paper was to assess the value of fresh urine sediment in the diagnosis of malakoplakia.

Use of Sialic Acid as a Complementary Method in the Cytological Diagnosis: Preliminary Study.

Introduction: Cellular morphology does not allow, in many cases, to safely establish a diagnosis of malignancy or benignity. Sialic acid is found in the membranes of well-differentiated mature cells, normally located in the alpha-2,3 position. During tumor progression, changes occur in glycosylation of proteins and lipids, including alterations in the sialylation patterns of tumor cells.

[Quality of the exo-endocervical sampling in the prevention of uterine cervix cancer].

Cervical and vaginal cytology, Papanicolaou test (PAP), is the most effective test for screening of preneoplastic lesions, and cervical cancer prevention. Its sensitivity goes from 50 to 98%, according to different statistics, and this variation is related to the sampling procedure. A satisfactory smear should be taken from the transformation zone, the junction between endocervix and exocervix.

New Biochemical Parameters in the Differential Diagnosis of Ascitic Fluids.

Background: In the cases of ascitis, it is essential to determine their origin using the parameters obtained by the cytological and biochemical examinations. The aim of this study was to evaluate the usefulness of different biochemical markers and the number of cells in the differential diagnosis of ascitic fluid (AF).

Methods: One hundred ninety-one cases of AF were studied, who were admitted to the hospital from January 01, 2009 to December 31, 2014.

Urothelial cells in smears from cervix uteri.

Objectives: To establish the cytological criteria to identify the urothelial cells in cervical smears in order to avoid mistakes in the cytological diagnosis.

Materials And Methods: Cervical smears from 34 post menopausal women with vesicovaginal fistulas, advanced bladder prolapse and genital erosive lichen planes (vulvar kraurosis) (Group 1) and transitional cell metaplasia of the cervix (TCM, Group 2) were stained with Papanicolaou technique. The cervical samples were taken during the routine annual examination for prevention of the uterine cancer.
