Helicobacter pylori infection and oncogene expressions in gastric carcinoma and its precursor lesions.

Although it is fairly well accepted that Helicobacter pylori infection plays a significant role in causing gastric cancer, the exact mechanisms involved in its pathogenesis are unclear. We have examined the relationship between H. pylori infection and oncogene expression in different stages of disease progression from precursor lesions to gastric carcinoma.

Clinical impact of identifying Trichomonas vaginalis on cervicovaginal (Papanicolaou) smears.

The purpose of this study was to understand how clinicians manage asymptomatic women after Trichomonas has been reported on Papanicolaou (Pap) smears. Clinical information was obtained from questionnaires sent to healthcare providers whenever Trichomonas was identified during the study period. Trichomonas was identified in 173 (1.

Clinical significance of identifying candida on cervicovaginal (Pap) smears.

This study was undertaken to determine the clinical significance of detecting candida on Pap smear. Clinical information was obtained from a questionnaire sent to the health care provider whenever candida was identified during the study period. Candida was identified in 309 (3.

Atypical glandular cells of undetermined significance on cervical smears. A study with cytohistologic correlation.

Objective: The incidence of endocervical adenocarcinoma has increased steadily over the past two decades. Since the Bethesda System was introduced, the diagnosis of atypical glandular cells of undetermined significance (AGUS) has also risen and now accounts for 0.46-1.

Cytologic diagnosis of Ki-1 lymphoma in pleural and peritoneal effusions: a case report.

This is a report of a case of Ki-1-positive large-cell anaplastic lymphoma in an 87-year-old man diagnosed on pleural and peritoneal fluids by cytomorphologic and immunohistochemical examination. Papanicolaou-stained smears revealed many single, large neoplastic cells containing one or two nuclei with occasional multinucleated cells having a wreath-like nuclear arrangement. The tumor cells expressed Ki-1 antigen and epithelial membrane antigen.
