摘要:

A case control study of women with carcinomain situ(CINIII) was undertaken comparing Papanicolaou smears for which false negative reports had been issued with slides for which true positive reports had been made. the number of abnormal cells was the strongest differentiating factor. Where there were less than 50 abnormal cells on the slide, the odds of a false negative report being issued was 23.7 times greater (95% confidence interval 3.7‐150) than when there were 200 or more abnormal cells. In false negative slides, the abnormal cells were likely to be not represented throughout the slide, present only as single cells rather than as groups, small in size and with finely granular normochromatic nuclei. We conclude that there are intrinsic differences between true positive and false negative slides. Given these characteristics, rapid rescreening of slides that are considered negative may not be an effective method of reducing the false negative rat

摘要:

Partial screening was performed on 10 800 cervical smears, comprising 8640 filed negative and unsatisfactory smears and 2160 newly received smears prior to conventional screening. Each slide was screened for 30 s and those considered abnormal were reviewed by standard screening. Partial screening led to the detection of 27 additional infections and 44 additional cytological abnormalities. These detection rates are better than those obtained with the traditional method of rescreening only a proportion of smears. Amongst the smears partially screened before conventional screening, partial screening detected 37‐66% of infections and 22‐71% of cytological abnormalities. We recommend the use of partial rescreening of all negatively reported smears as a method of internal quality control in cervical cytology laborator

摘要:

In Papanicolaou‐stained smears certain structures such as nucleoli,Pneumocystis carinii, Charcot‐Leyden crystals, bacteria and fungi show a brilliant fluorescence. the morphological characteristics of microorganisms which can be detected by this system, especially mycobacteria, are described. This screening method offers the possibility of providing the clinician with a provisional diagnosis within hours. Proof of the nature of the organisms should be obtained by cult

摘要:

A type of smokeless tobacco, known as Maras powder, is widely usedin lieuof cigarettes in the south‐eastern region of Turkey. In the present study, we evaluated cytological smears obtained from the lesion of lower lip mucosa of 80 smokeless tobacco users. There were severe epithelial abnormalities in seven out of the 80 subjects. Punch biopsies from these cases disclosed dysplasia in three cases, carcinomain situin two, and carcinoma in the other two cases. There was mild dysplasia in two punch biopsies of the remaining 73 cases. Oral cancer in tobacco powder users appeared to be related to the length of use, as it was observed only in subjects with 15 or more years of exposur

摘要:

The pilot study was undertaken to evaluate the role of FNA cytology in the clinical management of patients with thyroid swelling, in a District General Hospital (DGH) setting. One hundred and eleven patients were investigated over a period of 3 years, with a total of 142 fine needle aspirations. Statistical analysis showed a sensitivity of 71%, a specificity of 91% and a false negative rate of 2.7%. These results compare very favourably with other institutions. This study therefore shows that thyroid nodule FNA cytology can be performed in a DGH with a high standard of diagnostic accuracy, the results of which play a key role in patient management.
