A study was made of the contribution of the cytobrush to determining the composition of the cervical smear. From a population of women screened in The Netherlands in 1987, 733 women were selected whose smears for the second time in a row lacked endocervical cells. Note was made of method of contraception, age of the woman, and day of the menstrual cycle. A control group was formed of women whos...

background: cervical cancer is the third most common cancer in women in the world. papanicolaou smear is known as a standard test for cervical cancer screening; however, the most important challenge is high rates of false negative results. the aim of this study was to compare the quality of smears obtained by anatomical spatula and spatula-cytobrush. the most important factor in false negative ...

OBJECTIVE This prospective study aims to compare three different sampling techniques for the collection of endometrial cytological specimens in the mare: the guarded culture swab, the uterine cytobrush and the low volume uterine flush. MATERIAL AND METHODS The study population consisted of six healthy Standardbred mares in dioestrus. In each mare an acute endometritis was induced by performin...

Chlamydiae are now commonly detected in genital tract specimens in routine diagnosis by direct immunofluorescence. Direct immunofluorescence is as sensitive and specific as conventional culture.' Studies in our laboratory also suggest that direct immunofluorescence may be a valuable test for cure.2 One of the problems encountered with direct immunofluorescence, as with culture, is the need for ...

A comparison between nonspatula (cotton swab and Cytobrush) cervical sampling methods and spatula (wooden Ayre spatula and plastic extended-tip Szalay Cyto-Spatula) sampling methods was made in 109 cases. Based on the presence of endocervical cells, there were statistically significant qualitative differences between the non-spatula methods as well as between the spatula methods, but not betwee...

Subclinical endometritis has a major effect on the reproductive performance of dairy cows and also on the success of embryo collection. Thus it is important to minimize the number of false-negative diagnoses. In order to evaluate the question of whether or not a single cytobrush sample is representative of the whole endometrium, 53 German Holstein embryo donor cows in the northwest of Germany w...

Background: Numerous studies indicate that Papanicolaou smears contain better cellular material when the technique for collecting the sample employs the Zelsmyn Cytobrush TIl. Few studies, however, have examined its ability to increase the percentage of abnormal Papanicolaou smear results in actual clinical practice. Methods: This study looked at 7999 Papanicolaou smears done by 46 primary care...

In an attempt to increase Chlamydiazyme (Abbott Laboratories) detection of Chlamydia trachomatis antigen and to establish the reproducibility of positive results, we carried out an investigation into the usefulness of testing duplicate specimens, of more aggressive endocervical specimen collection by using cytobrushes instead of swabs, and of the repeated testing of both specimens from patients...

OBJECTIVES The Papanicolaou smear is a standard test for cervical cancer screening; however, the most important challenge is high false negative results. Several factors contribute to this problem and one the most important is inappropriate sampling. The aim of this study was to compare the quality of smears obtained by either an anatomical spatula or a spatula-cyto brush. METHODS One hundred...
