Comprehensive approach to diagnostic cytology in endometrial pathology (review of literature).

A cytological examination of uterine cavity material has proven to be the effective method of detecting and clarifying the diagnosis of cancer and non-tumor endometrial diseases. However, sometimes there are difficulties in interpreting the results in a traditional (classical) cytological examination, due to high level of inadequate samples: the presence of mucus, a large number of blood elements, structures of poorly visible cells in the wrong preparation of the smear. At present, the method of liquid cytology, based on the technology of preparation of standard thin-layer cytological preparations from liquid cell suspension, is increasingly developed and widespread.

[Impressionable cytology method in diagnostics of dry eye syndrome.].

Analysis of the cellular composition of the eyeball conjunctival prints and evaluation of the informative of the cytomorphological method of research in the diagnosis of dry eye syndrome (DES). Cytological examination using impression cytology was performed in 72 patients: 60 patients with DES and 12 without eye disease (control group). The main component of cytological sample in patients with DES are (a) squamous epithelium (hyperkeratocytes); (b) groups and clusters of flattened epithelial cells; (c) a small amount (up to five in the preparation) of goblet cells.

Sperm Sediment Cytology: A New Technique for Diagnosing Occult Urologic Infections.

Background: Ill-defined chronic symptoms such as itching, burning, urethral discharge, and pelvic pain are not uncommon in male urologic patients. Often, microscopic urinalysis, bacterial cultures, and laboratory testing are non-contributory. We have developed a technique for sperm sedimentation and used the cytologic examination of the sediment routinely in more than 4,000 patients with urologic complaints over the last 5 years.

Comparative Evaluation of β-Catenin and E-Cadherin Expression in Liquid Aspiration Biopsy Specimens of Thyroid Nodules.

We compared the results of gene molecular and immunocytochemical studies of β-catenin and E-cadherin in different variants of nodular thyroid disease (nodular colloid goiter, follicular thyroid adenocarcinoma, papillary thyroid cancer) and revealed changes of the function of the E-cadherin/β-catenin complex leading to switching from adhesion function of β-catenin in nodular colloid goiter to predominantly transcriptional activity in papillary carcinoma. The results confirm the important role of disturbances in E-cadherin-β-catenin interactions in the mechanisms of malignant transformation of follicular epithelium.
