Objectives: The majority of chlamydial and gonococcal infections in women are asymptomatic and, if left untreated, may result in serious sequelae. Simple and accurate testing of men and women at risk for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (GC) is the single most effective strategy for control of sexually transmitted infections. New tests using easy-to-acquire samples, such as the Papanicolaou (Pap) test, need to be validated in an effort to expand and improve detection. The objective of this study was to determine the performance of a new nucleic acid amplification test using two liquid-based cytology media for the detection of CT and GC.
Methods: The study was conducted in two phases at 11 geographically diverse, high- and low-prevalence sites. Three endocervical reference swabs as well as an endocervical SurePath or PreservCyt liquid cytology specimen sampled with a broom or brush/spatula were collected in a randomized order from each subject. Reference endocervical swabs were tested with three Food and Drug Administration-approved methods and compared to two new automated tests, the CT Q Amplified DNA Assay (CTQ) and the GC Q Amplified DNA Assay (GCQ).
Results: For the SurePath phase, 1838 subjects were enrolled. The sensitivity and specificity of the CTQ assay were 95.0% and 99.7%, respectively, and the GCQ assay was 100% for both. In the PreservCyt phase, 2164 subjects were enrolled. The sensitivity and specificity of the CTQ assay were 94.1% and 99.8%, respectively, and the GCQ assay was 95.3% and 99.95%, respectively. There was no significant difference in the results.
Conclusions: In this investigation, high sensitivity and specificity of the CTQ and GCQ assays were demonstrated for samples collected in either of two liquid-based cytology media when compared with endocervical swabs. The results were similar in both collection methods (broom or brush/spatula) and in high- and low-risk populations.

Thyroid cytopathology, particularly in cases of atypia of undetermined significance/follicular lesions of undetermined significance (AUS/FLUS), suffers from suboptimal sensitivity and specificity challenges. Recent advancements in digital pathology and artificial intelligence (AI) hold promise for enhancing diagnostic accuracy. This systematic review included studies from 2000 to 2023, focusing on diagnostic accuracy in AUS/FLUS cases using AI, whole slide imaging (WSI), or both.

Background: Liquid-based cytology (LBC) is a newer method of preparing cervical cell samples. This technique involves collecting cells in a liquid fixative and preparing and evaluating them.
Aim: This study aims to investigate cervical smears prepared using the Ezi-Prep LBC method and analyze the positivity rate for cervical cancer and assess the diagnostic accuracy of LBC in detecting cervical abnormalities among females with abnormal vaginal conditions attending a tertiary care center.

A cylindroma is a relatively rare tumor classified as a benign tumor with apocrine and eccrine differentiation, mainly occurring on the scalp. While there are some reports on the cytological findings of cylindromas, there are no reports concerning stamp preparation. Here, we report a case of a 60-year-old female who presented with a tumor on the right scalp.

Background And Objectives: We are reporting the performance of HPV self-sample collected by a novel kit in comparison with clinician collected cervical sample for HPV testing for cervical cancer screening.
Methods: Consenting, eligible women aged 25 to 60, with a positive cervical cancer screening test report in the past one year but without any prior treatment for cervical abnormalities were enrolled in the study. Each woman provided 2 samples for the HPV test (vaginal self-sample collected with the CERVICHECKTM, an indigenous kit from India and cervical sample collected by the clinician).

Introduction: To identify prognostic biomarkers that could predict how well patients will respond to lenvatinib/pembrolizumab (LEN/PEM). The utility of certain inflammatory biomarkers in endometrial liquid-based cytology (LBC) or peripheral blood samples, such as neutrophil counts, lymphocyte counts, and neutrophil-to-lymphocyte ratio (NLR) were explored.
Methods: The study included 25 patients with advanced or recurrent endometrial cancer who had received LEN/PEM between August 2018 and March 2024.
