Columnar and metaplastic cells in vault smears: cytologic and colposcopic study.

Vault smears (n = 250) were examined as routine follow up of hysterectomized individuals. Although the majority of these smears were normal, 14 of them revealed the presence of columnar cells or metaplastic cells. None of these patients had any known cause which could account for the presence of these cells in a post-hysterectomy smear. The possible explanations could be (i) the common mullerian origin of the upper vaginal mucosal cells, (ii) exfoliated reparative squamous parabasal and basal cells mimicking columnar cells, (iii) goblet cell metaplasia in atrophic vaginal epithelium.

The abnormal glandular smear: cytologic prediction, colposcopic correlation and clinical management.

We reviewed recent cytological reporting of abnormal glandular cells on cervical smears in order to assess the predictive value of these reports and the contribution of colposcopy in the assessment of these abnormalities. The study consisted of a 5-year retrospective review of the clinical management of 80 women with abnormal glandular cells on a cervical smear, with clinical and histopathological data available for review in the interval 1992-1996. There were two groups of women: (i) those referred with gynaecological symptoms and (ii) those with screen detected abnormalities who were asymptomatic and significantly younger than the first group. The predictive value of a glandular smear for malignancy was 42.5% and for premalignancy 28.8%. The most common lesions detected were cervical intraepithelial neoplasia (CIN) (13), endometrial cancer (13), cervical adenocarcinoma (10) and cervical intraepithelial glandular neoplasia (CIGN) (8). Four cases of endometrial carcinoma presented through screening. In the remainder a variety of benign conditions were identified as responsible for the abnormal smear. Failure to find an explanation for the abnormal smear only occurred in 8.8%. In developing a protocol for abnormal glandular smears, our observations indicate that: (a) those with abnormal bleeding require endometrial sampling; (b) for those with screen detected abnormality, colposcopy is valuable as it is a sensitive predictor of early invasion and can predict glandular abnormality; (c)diseases of the entire genital tract, non-gynaecological viscera and metastatic cancer can generate cytological abnormality; (d) screen detected borderline abnormality in endocervical cells is associated with CIN III.

Colposcopic and histologic findings and human papillomavirus (HPV) DNA test variability in young women positive for HPV DNA.

The purpose of this study was to determine the prevalence of human papillomavirus (HPV)-related disease in women positive for HPV DNA by using a commercially available DNA detection kit and to compare these results to HPV DNA variability observed in repeated sampling. Young women attending family planning clinics who were positive for HPV DNA on routine screening were asked to return for a repeat HPV DNA test, cytology, colposcopy, and biopsy if indicated. Of the 78 women examined, 35% had biopsy-verified low-grade dysplasia of the cervix, and 64% had evidence of HPV-related disease somewhere in the anogenital area. Fifty percent of the women had a negative test on repeat sampling, but there was no association between DNA persistence at the second visit and colposcopic/histologic findings. In conclusion, the minority of women positive for HPV DNA have latent infection. In addition, variability in detection is common and unrelated to the presence of HPV-related disease.

Hymenal colposcopic examination in sexual offenses.

Colposcopy, a method of more detailed examination of the cervix, widely used in the world but the application of this technique to forensic examinations is not. This presentation offers the benefits of the use of colposcopy in the examination of sexual assaults on women in a city in Brazil by a Medical Examiner of Mogi das Cruzes in the State of São Paulo near the megapolis of the same name. In 11.80%, or 59 of the 500 cases examined by the author, this technique has been of value to determine unsuspected trauma, fringed hymen, infantile hymen, healing, and accurate information in questionable cases.

Treatment of cervical intraepithelial neoplasia by colposcopically directed cryosurgery and subsequent pregnancy experience.

Of 420 patients attending a colposcopy clinic 204 were treated with outpatient cryosurgery for cervical intraepithelial neoplasia. It was possible to assess a definite outcome of therapy in 159 patients, and the lesion was successfully eradicated in 87% of them. Treatment failure appeared to be more common in patients of high parity, when the lesion extended into the cervical canal, and in those patients with large lesions. Failure appeared to be unrelated to patient age and to the histological grade of the lesion. In subsequent pregnancies utero-cervical function was preserved.
