Sodium benzoate, potassium sorbate, and methyl hydroxybenzoate are commonly used as preservatives in liquid pharmaceutical preparations. The purpose of this study is to determine the amount of the aforementioned preservatives in pharmaceutical products, as some recent studies have reported serious side effects associated with the ingestion of these substances. The content of 37 liquid pharmaceu...

Conventional Papanicolaou smear method is still commonly used for cervical cancer screening in Japan, despite the liquid-based cytology (LBC) that has become a global tendency in the world recently. One of the obstacles in the way of popularization of this method seems to be the confusion as to diagnosis upon cervical glandular lesions. We performed comparison study between LBC and conventional...

To improve the positive predictive value (PPV) for high-risk human papillomavirus (HR-HPV) in primary screening, DNA ploidy was measured on the same liquid-based sample by image cytometry in 984 cases showing discrepancies between cytology and HR-HPV testing. Of the conflicting results, 14.5% corresponded to a cytologic lesion (from atypical squamous cells of undetermined significance to high-g...

AIMS To assess the validity and practicality of real time polymerase chain reaction (PCR) for human papillomavirus (HPV) testing in combination with liquid based cytology samples for cervical screening. METHODS Real time PCR using consensus (GPS+/6+) and type specific primers was developed to detect genital HPV types. This provides rapid, efficient amplification followed by denaturation of th...

PURPOSE To determine the prevalence of abnormal cervical cytology, as diagnosed using a liquid-based cytology technique, in pregnant women attending the Antenatal Care (ANC) clinic at Siriraj Hospital. MATERIALS AND METHODS This cross-sectional study included 655 first-visit pregnant women who attended ANC clinic at Siriraj Hospital during June to November 2015 study period. After receiving r...

OBJECTIVE The aim of this study was to compare liquid-based endometrial cytology with hysteroscopy and endometrial biopsy regarding its diagnostic accuracy in a series of postmenopausal women with abnormal uterine bleeding (AUB) or asymptomatic women with thickened endometrium assessed by transvaginal ultrasound as a screening procedure. METHODS   Inclusion criteria were: menopausal status; t...

Our study aims to present the principal and the advantage of using the Liquid Based Cytology method by Cytoscreen system, as an alternative to the conventional Babes-Papanicolaou test, by reducing the false negative results frequency due to the poor quality of the smears and the epithelial cell screening by the blood elements, mucus or inflammatory exudates. A set of 1 054 female patients was a...

cancer in Korea has been released in this journal [1]. It was developed based on preexisting guidelines generated by the American Society for Colposcopy and Cervical Pathology (ASCCP) [2], the National Comprehensive Cancer Network [3], the United States Preventive Services Task Force [4], and the Institute for Clinical Systems Improvement [5]. Coincidentally, updated versions of ASCCP guideline...

OBJECTIVE Early detection and diagnosis of endometrial carcinoma and precancerous change would undoubtedly become the most alluring part for researchers. With the emergence of endometrial brush samplers, a new upsurge in endometrial cytology is in the making. But endometrial specimens obtained by the endometrial brush samplers require special preservation solution. The objective of this study i...
