New possibilities of complex ttreatment of cervical ectropion

Introduction. Ectropion of the cervix (EC) is a condition when there is a cicatricial deformity of the uterine cervix (as a result of traumatic injuries) with visualization of the ectopic columnar epithelium on the vaginal part of it. The ectopia is currently classified as a variant of the normal histophysiological state of the cervix. This article discusses the features of the course and methods of treatment of complicated EC.Objective of the study is: to develop and evaluate the effectiveness of a new method of complex treatment of CE.Material and methods. In an open prospective study, 133 patients with CE (groups 1 and 2) and 56 healthy women (group 3) has taken part. In group 1 (n = 83), we have used a method for treating CE developed by us, which included two stages: stage I – elimination of microbial and viral pathogen in combination with immunomodulatory therapy, II – electrosurgical treatment (Leep biopsy) and treatment of the cervix with Galavit (100 mg of dry matter) dissolved in 5 ml of Miramistin (Patent for invention RU 2568768 C1). In group 2 (n = 50), surgical treatment of CE has been preceded by vaginal sanitation, empirical antibacterial and antiviral therapy. Diagnostic measures, in addition to standards, have included: determination of interleukins IL-1β, IL-6, IL-8, IL-10 in the discharge of the cervical canal, ultrasound diagnostics with Doppler measurements in the vessels of the central zone of the cervix. Statistica 7.0, SPSS 17 packages have been used for statistical processing.Results and discussion. Before the start of treatment, patients in groups 1 and 2 have been found to have a combination of CE with cervicitis (100%), ASCUS cytological picture (more than 60%), abnormal colposcopic signs (100%), imbalance of the local immune system with a predominance of Th1 cytokines (the content of IL-8 increased 2.6 times; IL-1b – 13 times; IL-6 – 20 times, and IL-10 – in 1.7 times) against the background of increased vascularization and cervical perfusion. The reparative process after Leep biopsy in group 1 has ended by the end of 3 weeks in 65.6% of patients, in group 2 – in 25.5%, after 5 weeks – in 100% and 57.4%, respectively, after 8 – in group 2, 91.5%. The average period of epithelialization of a wound on the cervix in group 1 was 27.4 ± 4.3 days, in group 2 – 39.5 ± 5.6 days (p = 0.01). After 2 years, the recurrence of cervical pathology has been recorded only in group 2 (34.0%).Conclusion. The use of the developed method of two-stage complex therapy for CE increases the effectiveness of treatment, prevents complications after Leep biopsy, accelerates epithelialization by 30.6% and avoids recurrence of the disease

Liquid-shaped microlens for scalable production of ultrahigh-resolution OCT microendoscope

Endoscopic optical coherence tomography (OCT) is a valuable tool for providing diagnostic images of internal organs and guiding interventions in real time. Miniaturized OCT endoscopes are essential for imaging small and convoluted luminal organs while minimizing invasiveness. However, current methods for fabricating miniature fiber probes have limited ability to correct optical aberrations, leading to suboptimal imaging performance. In this study, we introduce a new paradigm of liquid shaping technique for the rapid and scalable fabrication of ultrathin and high-performance OCT microendoscopes suitable for minimally invasive clinical applications. This technique enables the flexible customization of freeform microlenses with sub-nanometer optical surface roughness by regulating the minimum energy state of curable optical liquid on a wettability-modified substrate and precisely controlling the liquid volume and physical boundary on a substrate. Using this technique, we simultaneously fabricated 800-nm OCT microendoscopes with a diameter of approximately 0.6 mm and evaluated their ultrahigh-resolution imaging performance in the esophagus of rats and the aorta and brain of mice.Comment: 42 pages, 7 figures in the main tex

Diagnosis of Cervical Cancer and Pre-Cancerous Lesions by Artificial Intelligence: A Systematic Review

The likelihood of timely treatment for cervical cancer increases with timely detection of abnormal cervical cells. Automated methods of detecting abnormal cervical cells were established because manual identification requires skilled pathologists and is time consuming and prone to error. The purpose of this systematic review is to evaluate the diagnostic performance of artificial intelligence (AI) technologies for the prediction, screening, and diagnosis of cervical cancer and pre-cancerous lesions
