Evaluation of Specimen Types for Pima CD4 Point-of-Care Testing: Advantages of Fingerstick Blood Collection into an EDTA Microtube.

Effective point-of-care testing (POCT) is reliant on optimal specimen collection, quality assured testing, and expedited return of results. Many of the POCT are designed to be used with fingerstick capillary blood to simplify the blood collection burden. However, fingerstick blood collection has inherent errors in sampling. An evaluation of the use of capillary and venous blood with CD4 POCT was conducted.

Pre-analytic error: A significant patient safety risk.

Ancillary testing in cytopathology has grown dramatically over the past decade, enhancing the clinical value of cytology specimens obtained via minimally invasive methods. However, a complex testing landscape brings with it new and emerging risks to patient safety. Recognition of complicated systems issues as well as shared responsibility in process ownership can help to minimize safety risks. Because pre-analytic factors account for the majority of errors in pathology, attention to operational steps (test ...

Saliva as a diagnostic specimen for testing respiratory virus by a point-of-care molecular assay: a diagnostic validity study.

Automated point-of-care molecular assays have greatly shortened the turnaround time of respiratory virus testing. One of the major bottlenecks now lies at the step of the specimen collection especially in a busy clinical setting. Saliva is a convenient specimen type which can be provided easily from adult patients. This study assessed the diagnostic validity, specimen collection time, and cost associated with the use of saliva.

Automated Cervical Screening and Triage, Based on HPV Testing and Computer-Interpreted Cytology.

State-of-the-art cervical cancer prevention includes human papillomavirus (HPV) vaccination among adolescents and screening/treatment of cervical precancer (CIN3/AIS and, less strictly, CIN2) among adults. HPV testing provides sensitive detection of precancer but, to reduce overtreatment, secondary "triage" is needed to predict women at highest risk. Those with the highest-risk HPV types or abnormal cytology are commonly referred to colposcopy; however, expert cytology services are critically lacking in man...

Preference for Human Papillomavirus Self-Collection and Papanicolaou: Survey of Underscreened Women in North Carolina.

Self-collection of samples for human papillomavirus (HPV) testing (self-collection) has the potential to increase cervical cancer screening among underscreened women. We assessed attitudes toward at-home HPV self-collection compared with clinic-based Pap testing in this higher-risk population.

Moving towards an organized cervical cancer screening: costs and impact.

HPV screening has been shown to be more cost-effective than cytology screening under most scenarios. Furthermore, it should be offered only in organized programmes with good quality assurance mechanisms. This study analyses the comparative cost of the current policy of opportunistic cytology screening vs. a hypothetical organized programme based on primary HPV screening.

Comparison of siriraj liquid-based solution and standard transport media for the detection of high-risk HPV in cervical specimens.

To evaluate the performance of Siriraj liquid-based solution for HPV DNA testing compared with standard transport media METHODS: This cross-sectional study enrolled 217 women aged 30 years or older who attended for cervical cancer screening or had abnormal cervical cytology or were diagnosed with cervical cancer at the Department of Obstetrics-Gynecology, Siriraj Hospital from March 2015 to January 2016. We excluded patients with a history of any cervical procedures, hysterectomy, or previous treatment with...

Comparison of HPV genotyping and cytology triage, COMPACT-Study: Design, methods and baseline results in 14,642 women.

While cytology-based screening programs have significantly reduced mortality and morbidity from cervical cancer, the global consensus is that primary human papillomavirus (HPV) testing for cervical screening increases detection of high-grade cervical intraepithelial neoplasia (CIN) and invasive cancer. However, the optimal triage strategy for HPV-positive women to avoid over-referral to colposcopy may be setting specific. Since Japan requires data that has been generated domestically to modify screening gui...

Prevalence of intraepithelial lesion in cervical screening cytology in a First-level Care Unit

Cervical cancer represents the second leading cause of malignant neoplasm mortality in women globally. Cervical cytology is the most important screening study. It is therefore of interest to know the prevalence of cytological alterations in the Mexican population. In this study the objective was to calculate the prevalence of intraepithelial lesion in cervical screening cytology.

The use of p16/Ki-67 dual staining technology on cervical cytology of patients undergoing a LLETZ procedure.

The main objective of this prospective observational study was to investigate the diagnostic performance of the p16/Ki-67 dual stain technique (DST) for detecting CIN 2+ in a LLETZ referral setting. Test performances were compared with HR-HPV testing and Pap cytology.

The Diagnostic Accuracy of Cytology for the Diagnosis of Hepatobiliary and Pancreatic Cancers.

Although cytology testing is considered a valuable method to diagnose tumors that are difficult to access such as hepato-biliary-pancreatic (HBP) malignancies, its diagnostic accuracy remains unclear. We therefore aimed to investigate the diagnostic accuracy of cytology testing for HBP tumors.

Cervical screening in HPV-vaccinated populations.

Cervical screening with cytology has been the basis for substantial reductions in cervical cancer incidence and mortality in most high-income countries over the last few decades. More recently, there have been two key, parallel developments which have prompted a major re-consideration of cervical screening. The first is the emergence of evidence on the improved sensitivity of human papillomavirus (HPV) DNA testing compared to cytology, and the second is the large-scale deployment of prophylactic vaccination...

Ichthyological collection of the Museu Oceanográfico D. Carlos I.

The collection of the Museu Oceanográfico D. Carlos I is a historical specimen, instrument, and document collection that has been housed at the Aquário Vasco da Gama since 1935. The collection is largely the result of several scientific campaigns conducted by Dom Carlos de Bragança between 1896 and 1907. Specifically, the ichthyological collection consists of 675 surviving catalogue records of specimens caught, acquired or offered to D. Carlos I between 1892 to 1907, and includes the type specimen for B...

The pragmatic role of nasal cytology: a point-of-care testing to implement precision medicine in clinical practice.

Precision medicine is an up-to-date strategy aimed at individualizing precise pathophysiological mechanisms. Thus, precision medicine is the basis for personalized medicine, inasmuch as it seeks to define the most appropriate treatment for each patient. Nasal cytology requires only an optical microscope, stains, glasses, and nasal cytology curettes. The procedure may last very few minutes using quick staining and, therefore, it can be considered a reliable point-of-care test in the office setting.

Randomised trial of HPV self-sampling among non-attenders in the Slovenian cervical screening programme ZORA: comparing three different screening approaches.

Background To overcome obstacles within the Slovenian organised cervical cancer screening programme, a randomised pilot study of human papillomavirus (HPV) self-sampling among non-attenders was performed, aiming to assess three different screening approaches. Participants and methods Non-attenders aged 30-64 years from two Slovenian regions were randomised to two HPV self-sampling groups-the opt-in (I1, n = 14.400) and the opt-out (I2, n = 9.556), with a control group (P, n = 2.600). Self-collected samples ...

Socio-economic variations in anticipated adverse reactions to testing HPV positive: Implications for the introduction of primary HPV-based cervical screening.

Some cervical cancer screening programmes are replacing cytology with human papillomavirus (HPV) DNA testing as the primary screening test. Concerns have been previously raised around the potential psychosocial impact of testing positive for HPV. We analysed socio-economic variations in anticipated adverse reactions to testing positive for HPV in women of screening age in the general population. A questionnaire was mailed to a random sample of 5553 women aged 20-64 in 2010, selected through primary care in ...

Clinical Utility of CINtec PLUS Triage in Equivocal Cervical Cytology and Human Papillomavirus Primary Screening.

While cervical cytology is accepted triage for human papillomavirus (HPV)-positive women, the efficiency of cervical screening could be improved by exploiting disease markers with higher specificity.

Diagnostic performance of the E6/E7 mRNA-based OPTIMYGENE HR-HPV RT-qDx assay for cervical cancer screening.

Pap smear and high-risk human papillomavirus (HR-HPV) DNA testing are the most widely applied methods for cervical cancer screening, but both methods are limited by their low specificity and lack of association with the patients' prognoses. The aim of the study was to compare the clinical and prognostic significance of HPV E6/E7 mRNA as an early biomarker with cytology and HPV DNA detection in cervical cancer screening.

Dual p16 and Ki-67 Expression in Liquid-Based Cervical Cytological Samples Compared to Pap Cytology Findings, Biopsies, and HPV Testing in Cervical Cancer Screening: A Diagnostic Accuracy Study.

Our objective was to verify the sensitivity and specificity of dual immunocytochemistry staining for p16 and Ki-67 in liquid-based samples (the "dual" assay) for cervical lesion screening, compared to biopsy findings and human papillomavirus (HPV) DNA molecular detection.

Patterns of repeated anal cytology results among HIV-positive and HIV-negative men who have sex with men.

Men who have sex with men (MSM) are at increased risk for anal cancer. In cervical cancer screening, patterns of repeated cytology results are used to identify low- and high-risk women, but little is known about these patterns for anal cytology among MSM.

Optimizing the Use of a Voided Urine Cytology Specimen as Control Material for Anti-BK Virus Immunohistochemical Staining.

The use of colposcopic punch biopsy in the management of abnormal cervical cytology: a 5-year retrospective audit.

The aim of this study was to determine the accuracy of colposcopic punch biopsy to detect cervical epithelial neoplasia (CIN) II + in patients with abnormal cervical cytology and the major colposcopic findings in patients who underwent a loop electrosurgical excision procedure (LEEP), subsequently. A total of 231 patients with abnormal cervical cytology who underwent a colposcopy guided cervical biopsy and subsequent LEEP were analysed. The mean age was 33.4 ± 8.7 years. CIN II + rate on LEEP p...

Reliable identification of women with CIN3+ using hrHPV genotyping and methylation markers in a cytology-screened referral population.

Cervical screening aims to identify women with high-grade squamous intraepithelial lesion/cervical intraepithelial neoplasia 2-3 (HSIL/CIN2-3) or invasive cervical cancer (ICC). Identification of women with severe premalignant lesions or ICC (CIN3+) could ensure their rapid treatment and prevent overtreatment. We investigated high-risk human papillomavirus (hrHPV) detection with genotyping and methylation of FAM19A4/miR124-2 for detection of CIN3+ in 538 women attending colposcopy for abnormal cytology. All...

Patch Testing for the Evaluation of Metal Hypersensitivity in the Nuss Procedure: A Review of the Literature.

The Nuss procedure has become the predominant reason for the use of metal implants by pediatric general and thoracic surgeons. Current guidelines recommend preimplant testing for all patients undergoing the Nuss procedure, which differs from the guidelines for all other orthopedic procedures. This review was done to further evaluate this discrepancy.

Hyalinizing Trabecular Tumor of the Thyroid Gland, a Diagnostic Challenge in Fine-Needle Aspiration Cytology: Case Report.

Hyalinizing trabecular tumor (HTT) is a rare thyroid tumor with low to minimal malignant potential. HTT is often misinterpreted as other thyroid tumors, including papillary thyroid carcinoma (PTC) and medullary thyroid carcinoma (MTC), on fine-needle aspiration (FNA) cytology, because of its overlapping cytologic features, such as nuclear grooves and intranulcear pseudoinclusions. Although cytopathologists cannot definitely conclude HTT by FNA cytology, suspicion of HTT is necessary to avoid misdiagnosing H...
