Usefulness of repeat cytology at the time of first colposcopy.

The value of repeat cytology in the detection of high-grade preinvasive or invasive disease was analyzed at the time of colposcopy in cases of patients with abnormal referral cytology. A series of 136 patients with squamous abnormalities in their referral cytology, who had undergone repeat cytology and for whom outcome had been established, were included in the study. Final diagnosis consisted of 27 negative results (20%), 37 cases of CIN1 (27%), 31 CIN2 (23%), 39 CIN3 (29%), and 2 (1%) cases of squamous cell carcinoma (SCC).

[Helicobacter pylori identification by brush gastric cytology: a comparison with histologic method].

The purpose of this study was to verify the efficacy of brush gastric cytology for diagnosis of Helicobacter pylori infection in patients, submitted to elective gastroscopy, compared to the method of endoscopic histology. Endoscopy was performed on 157 patients, divided into two dyspeptic groups: group A (n = 27) with duodenal ulcer; and group B (n = 130) without ulcer. In group A, the percentage of positive cases detected by brush cytology (77.
