Filter by:Cervical cancer screening is important as it enables identification of women at increased risk of the disease, but high-quality diagnostics of screen-positive women and effective treatment of those with precancer are critical in preventing progression to cancer. With the current transition from cytology-based to primary human papillomavirus (HPV)-screening and a growing proportion of HPV-vaccinated women, diagnostics of screen-positive women will become more challenging in the decades to come. Thus, there is a need to explore how to improve diagnostics while ensuring a low number of unnecessary procedures such as colposcopy and the collection of multiple cervical biopsies. The overall purpose is: - To investigate the diagnostic accuracy of cervical precancer when using a colposcopic scoring system in the diagnostic work-up of screen-positive women. - To investigate the performance of a colposcopic scoring system to identify women without cervical precancer in whom collection of biopsies can be safely omitted.
The goal of this observational study is to compare the accuracy and sensitivity of High-throughput human papilloma virus(HPV) typing and integrated assays with routine screening protocols (Cobas HPV test combined with thinprep cytologic test(TCT) for the detection of cervical intraepithelial neoplasia in the general and hospital populations. The main questions it aims to answer are: - High-throughput HPV typing and integrated assays can screen for ≥ cervical intraepithelial neoplasia (CIN2 or CIN3) with high sensitivity and accuracy. - High-throughput HPV typing and integrated assays can be promoted as a screening tool for cervical cancer. Participants will be screened with routine screening protocols (Cobas HPV test combined with TCT test), and if the results are abnormal, colposcopy and cervical biopsy will be performed.
The goal of this clinical study is to compare the clinical performance of a new 2-steps universal adhesive in patients with non-carious cervical lesions. The main question it aims to answer is: Is there any difference in clinical performance of a new 2-steps universal adhesives bonded with different etching strategies. Participants will have restorations using a new 2-steps universal adhesives in different etching strategies. - etch-and-rinse - selective enamel etching - self-etch
Preheating resin composites is the warming of resin composites by using a heating device (composite warmer) before its placement. Preheating increases the flow properties and allows better adaptation to cavity preparation. The high thermal energy also improves polymerization rate, thereby reducing microleakage. Conventional composites resin is used as one-paste light-cured systems, which are built up in increments to overcome the effects of setting shrinkage and to ensure thorough curing. Several studies report failure of cervical restorations of noncarious cervical lesions and an incessant search for the most suitable restorative material. Therefore, this study aims to evaluate the clinical performance of conventional resin composites compared with preheated resin composites in the treatment of noncarious cervical lesions. Our null hypothesis states that there is no difference between the clinical performance of preheated resin composites and conventional resin composites in the treatment of noncarious cervical lesions. This study will be conducted at the Conservative and Endodontics Department in Polyclinic B, Faculty of Dentistry, Manipal University College Malaysia (MUCM). It involves forty-six randomly selected patients with two similar noncarious cervical lesions, each on a canine, first premolar, second premolar or first molar on the contralateral side of the maxillary arch. One lesion will be restored with preheated resin composite (3M™ Filtek™ Z350 XT Universal Restorative) while the other lesion will be restored with conventional resin composite (3M™ Filtek™ Z350 XT Universal Restorative). Both restorations will be done on each patient's first visit. The patients will be recalled 1,3 and 6 months later for assessment of the restorations, using modified US Public Health Service (USPHS) criteria: marginal integrity, marginal discoloration, wear, retention, secondary caries and postoperative sensitivity.
The application of artificial intelligence in image recognition of cervical lesions diagnosis has become a research hotspot in recent years. The analysis and interpretation of colposcopy images play an important role in the diagnosis，prevention and treatment of cervical precancerous lesions and cervical cancer. At present, the accuracy of colposcopy detection is still affected by many factors. The research on the diagnosis system of cervical lesions based on multimodal deep learning of colposcopy images is a new and significant research topic. Based on the large database of cervical lesions diagnosis images and non-images, the research group established a multi-source heterogeneous cervical lesion diagnosis big data platform of non-image and image data. Research the lesions segmentation and classification model of colposcopy image based on convolutional neural network, explore the relevant medical data fusion network model that affects the diagnosis of cervical lesions, and realize a multi-modal self-learning artificial intelligence cervical lesion diagnosis system based on colposcopy images. The application efficiency of the artificial intelligence system in the real world was explored through the cohort, and the intelligent teaching model and method of cervical lesion diagnosis were further established based on the above intelligent system.
This study evaluates the Dynamic Spectral Imaging (DSI) Colposcope (DySIS) in it's ability to diagnose cervical dysplasia. Half of participants with be examined by the DySIS colposcope, there the other half will be examined by standard colposcopy.
This study evaluates the effect and feasibility of expanding the target population in the Danish cervical cancer screening program to include women aged 65 to 69 years. The study also evaluates if HPV self-sampling constitutes an appropriate screening method among older women.
Prevention of cervical cancer with cervical screening is one of the most successful screening activities in medicine. In Sweden, screening was implemented in the 1960s and has since prevented tens of thousands of women from having cervical cancer. Individual invitations to screening result in increased attendance therefore evaluating strategies for reaching women through invitations is particularly valuable. Women who regularly attend screening following an invitation reduce their risk of cervical cancer by as much as 90%. Of the women who are diagnosed with cervical cancer (about 550 women per year in Sweden), as many as 38% did not participate in the screening. Invitations for screening are sent to the entire population in Sweden aged 23-70. The current coverage of screening is 82.9%, which represents the proportion of women ages 23-70 who attend according to recommendations. In addition, many women are sporadic attenders who reduce their risk for cancer somewhat. The highest cancer risk is seen among those women who have never participated as well as women who have had a history of precancerous lesions or HPV infection but have not been followed-up. Cervical cancer is the first form of cancer for which there are approved molecular screening tests (HPV test). Unlike the older screening method (cytology), self-collected samples can be analyzed for HPV (the analysis method is so sensitive that it does not matter if the sample is not optimally taken). Invitations and reminders about cervical screening are sent by letter to the woman's home address (about 3 million letters per year in Sweden). This strategy results in a waste of resources and has a negative environmental impact. Regarding reminders, we have seen in previous research that the effect is not optimal. When sending a physical reminder letter to women who have not participated in more than 10 years (current routine), only 2% of the women invited came for sampling. Reminders with SMS are now standard for many businesses in society, such as car testing or dental appointments. It is inexpensive, saves the environment and there are studies that suggest it is more effective than sending physical letters. In this study, we intend to investigate whether SMS reminders, electronic letters, and physical letters for screening lead to increased participation and thus to a higher proportion of detected, treatable precursors of cervical cancer compared to before.
Intubation processes of patients under general anesthesia are important in terms of patient morbidity and mortality. The cervical region has also anatomical and physiologic speciality in which stability of the general condition of the patient during this intubation process. The cervical region needs to be manipulated very carefully due to respiratory center, cardiovascular balance and neurological integrity. During general anesthesia, the patient will be under the effect of muscle relaxant and especially the cervical region becomes vulnerable to trauma. The intubations made by affecting the cervical region as little as possible change the morbidity and mortality. Intubation with fiberoptic bronchoscopy and videolaryngoscopy has reduced the complications that other methods can cause. Awake intubation with fiberoptic bronchoscopy and videolaryngoscopy is important for neurological evaluation during the procedure. In this study, we aimed to compare awake intubation by videolaringoscopy and fiberotic bronchoscopy in patients with intubation difficulties due to restriction of neck movements in cervical surgery.
