Morphological differences of the fallopian tube ampoule in young and old age

Работа основана на морфологическом исследовании ампул маточных труб 130 рожавших женщин молодого и старческого возраста. Применены макрометрический, гистологический, иммуногистохимический и микрометрический методы исследования. Выявлены закономерности возрастной морфологической изменчивости ампулы маточной трубы, проявляющиеся в уменьшении параметров их длины, а также наружных диаметров в середине ампулы и в местах перехода перешейка в ампулу и ампулы в воронку от молодого возраста к старческому возрасту. Гистоархитектоника ампул маточных труб у женщин в старческом возрасте характеризуется уплощением эпителия слизистой оболочки, образующей обилие близлежащих утолщенных складок, формирующих неравномерное сужение просвета ампулы. Определяется истончение мышечной оболочки с разрастанием вместо нее соединительной ткани и скоплением адипоцитов в подсерозной основе. В старческом возрасте отмечается более выраженная экспрессия виментина, прослеживающаяся не только в эндотелии и субэндотелиальном слое кровеносных сосудов, включая капилляры, но и в отдельных фибробластах. Установлено, что особенности микрометрических характеристик ампул маточных труб заключаются в уменьшении внутреннего периметра эпителиальной выстилки и площади просвета, наряду с увеличением площади их стенки при срединном сечении, в старческом возрасте в сравнении с молодым. The work is based on a morphological study of ampoules of the fallopian tubes of 130 young and senile women who gave birth. Macrometric, histological, immunohistochemical and micrometric methods of investigation were applied. The regularities of age-related morphological variability of the fallopian tube ampoule are revealed, which are manifested in a decrease in the parameters of their length, as well as external diameters in the middle of the ampoule and at the places of transition of the isthmus into the ampoule and ampoule into the funnel from young age to old age. Histoarchitectonics of ampoules of the fallopian tubes in women in old age is characterized by flattening of the epithelium of the mucous membrane, which forms an abundance of nearby thickened folds that form an uneven narrowing of the lumen of the ampoule. The thinning of the muscle membrane is determined with the growth of connective tissue instead of it and the accumulation of adipocytes in the subserose base. In old age, there is a more pronounced expression of vimentin, which can be traced not only in the endothelium and subendothelial layer of blood vessels, including capillaries, but also in individual fibroblasts. It was found that the features of the micrometric characteristics of the fallopian tube ampoules consist in a decrease in the inner perimeter of the epithelial lining and the lumen area, along with an increase in the area of their wall at the median cross-section in old age compared with young age.

Endometriosis’s impact on reproductive structures and its treatment

Endometriosis is a painful, chronic disease affecting approximately 10% of all women at reproductive age, and from the most common locations where endometriosis is found: the ovary, fallopian tubes, and uterine ligaments, and, less commonly they are found in the lung, the bladder, rectum, and intestines. It is known that endometriosis, in the reproductive organs, causes pelvic pain before or during menstruation, difficulty in pregnancy or infertility, for reasons that are not entirely clear, but some theories have tried to explain this phenomenon and confirmed that it may be a result of a defect in the immune and hormonal system in addition to some factors that affect egg’s quality and the movement of the gametes and therefore reproduction function. Treatment options now focus on pain management and attempting to limit the progression of implants, using a range of hormonal medications such as anti-progesterone, progestin, oral contraceptives, and GnRH, also including surgical procedures such as endometriosis and adhesion tissue. In this review, weshed light on the damage and issues that women may face due to this disease. We discuss some alternative solutions used by specialists for patient susceptibility.

Synchronous papillary endometrial and ovarian cancer in a 64-year-old woman

Obesity, nulliparity, and comparatively younger age may attribute a “hormonal field effect” which leads to the development of synchronous endometrioid cancers. The morphological unit consisting of the uterus, fallopian tubes, and ovary as part of the Mullerian system may explain the synchronous appearance of these malignancies. Synchronous endometrial and ovarian cancer (SEOC) is defined as the simultaneous presence of these dual cancers at the time of diagnosis as opposed to metachronous cancer where these two cancers are diagnosed at different chronologic time points. Synchronous malignancies in the female genital tract are very rare entities. Synchronous endometrial and ovarian tumors must be differentiated from either primary endometrium or ovarian tumors with metastasis. The landmark criteria for diagnosing such cases have been laid down by Ulbright and Roth.

Spectrum of Lesions in the Fallopian Tubes – A Histopathogical Study

Introduction: The Fallopian tubes are a pair of narrow tubular structures connecting the ovary and the uterus. It is usually the site of fertilization and plays a very important role in the fusion of the sperm and ovary and helps in movement of the fertilized zygote to the uterus. Even though being an organ of very small size the importance of the variety of lesions occurring in the fallopian tubes is often not considered. Biopsies of the fallopian tubes are taken to show the different lesions found in the tubes. Aim: The main aim of the study is to study the spectrum of lesions occurring in the fallopian tubes and correlation of these findings with its clinical parameters. Study Design: This is a retrospective descriptive study Place and Duration of Study: Department of Pathology, Saveetha Medical College, Saveetha Institute of Medical and Technical Sciences, Thandalam, Chennai between June 2019- December 2019. Methodology: A retrospective study of all the fallopian tube specimens sent for routine histopathological analysis over a period of 6 months was carried out. The different pathological lesions were observed from the relevant clinical data and the correlation with its clinical parameters was done. Results: A sample size of 77 specimens was collected among which the commonest age group which was found to have the highest number of lesions was between 26-30 years. This was found to be in correlation to the reproductive age group of women. The most common form of pathological lesion observed was ectopic pregnancy (about 46% of total pathological lesions), followed by Paratubal cysts (23%), Hydrosalpinx (15%) and Hematosalpinx (8%). Cystadenoma was the only benign tumor observed in this study and constituted 8% of the total pathological lesions. Conclusion: This study shows the importance of histopathological examination of all fallopian tube specimens with or without abnormal findings.

Ayurveda Interventions in the Management of Tubal Blockages- Case Studies

Failure to conceive within one or more years of regular unprotected coitus is defined as Infertility. Tubal blockage is one of the most common causative factors in female infertility. The prevalence is 19.1% in the fertility age group. This condition is not described in Ayurvedic classics as itself tubal blocks but Blockages of fallopian tubes can be better correlated with Vandhyatvadue to Artavbijavahasrotavrodha (Blockages in fallopian tubes). All three doshas are responsible for causing blockages. Normalizing the vitiated Vata-kapha-doshaleads to restoration of tubal function and easy conception. Here are two cases with bilateral tubal blockage which were treated successfully with certain Ayushakti herbal remedies and Uttarbasti (Intrauterine enema) with Ksharbasti. Recording and publishing this data is worthwhile as there are minimum chances of complication with assured results. With this treatment we can definitely avoid unnecessary use of hormones and IVF protocol and can give cost effective and promising results

Multi-modal Profiling of the Extracellular Matrix of Human Fallopian Tubes and Serous Tubal Intraepithelial Carcinomas

Recent evidence supports the fimbriae of the fallopian tube as one origin site for high-grade serous ovarian cancer (HGSOC). The progression of many solid tumors is accompanied by changes in the microenvironment, including alterations of the extracellular matrix (ECM). Therefore, we sought to determine the ECM composition of the benign fallopian tube and changes associated with serous tubal intraepithelial carcinomas (STICs), precursors of HGSOC. The ECM composition of benign human fallopian tube was first defined from a meta-analysis of published proteomic datasets that identified 190 ECM proteins. We then conducted de novo proteomics using ECM enrichment and identified 88 proteins, 7 of which were not identified in prior studies (COL2A1, COL4A5, COL16A1, elastin, LAMA5, annexin A2, and PAI1). To enable future in vitro studies, we investigated the levels and localization of ECM components included in tissue-engineered models (type I, III, and IV collagens, fibronectin, laminin, versican, perlecan, and hyaluronic acid) using multispectral immunohistochemical staining of fimbriae from patients with benign conditions or STICs. Quantification revealed an increase in stromal fibronectin and a decrease in epithelial versican in STICs. Our results provide an in-depth picture of the ECM in the benign fallopian tube and identified ECM changes that accompany STIC formation. (J Histochem Cytochem XX: XXX–XXX, XXXX)

THE QUALITY OF BEE QUEENS OBTAINED BY DIFFERENT METHODS

Honeybees can only live and work in a bee colony. There is normally only one queen bee in a standard bee colony. It is the family's only fully matured female and the mother of young queen, drone, and worker bees. When a bee colony loses its queen bee and is unable to reproduce a new one, it eventually dies. Timely change of queen bees every 2 years, as well as increasing and maintaining the strength of bee colonies are the main zootechnical measures to maintain optimal life of bees and get the maximum amount of products from them. The presence of the queen bee in the bee family of honey bees fully influences their flight activity in collecting bee pollen. In its absence, the harvesting of pollen and its processing, as well as the extraction of wax and the construction of honeycombs, the cultivation of brood, and the collection of nectar are significantly slowed down and then completely stopped. With the advent of the uterus, all the functions of the family as a whole biological system are restored. Therefore, the quality of queens is a determining factor in the viability and productivity of the bee colony. The aim of the study was to compare the quality of reproductive function of queen bees of Apis mellifera sossimai and Apis mellifera carpatica breeds in different ways of obtaining them, and the impact on productivity of the bee colony. To carry out experimental work in the apiary, three control groups and two experimental groups were formed, with nine bee colonies in each group. In the first group, the queen bees were artificially breeded from the nursery, in the second group - fistulous queens bees, and in the third - the swarm queen bees. The apiary is situated on a 50-50 meter plot of land. Hives are used to keep bee colonies. Bees are kept in the apiary of the Ukrainian field breed. A pollinating honey area is available at the apiary. A winter house, a mobile vehicle, and a suitable chamber for honey pumping are all available at the apiary. Mustard is sown around the apiary every year. According to the study, big full-fledged queen bees are born in a healthy, physiologically complete bee colony. When the strength of a bee colony was increased, the queen bees were born 30 mg lighter. The number of fallopian tubes of queen bees raised with a biological integrity breach is 185,1 ± 7,3, while the number of fallopian tubes of queen bees raised with biological integrity is 207,6 ± 7,4. If the bees bring nectar and pollen during the breeding process, the queen bees are born huge, but without the forage а little and with poor executive abilities. It makes no difference how strong the foraging is; even 200 – 300 g of nectar and pollen per day has a positive impact on the quality of queen bees produced. Fistula uteruses had higher egg production compared to swarms in the same conditions of colony development.

Isolated Fallopian Tube Torsion: A Rare Entity

Isolated fallopian tube torsion is an extremely rare occurrence in a young female. The lady concerned presented with acute abdominal pain and the ovaries were normal on the scan with dilated fallopian tubes. On laparoscopy, it was revealed that she was suffering from fallopian tube torsion and laparoscopic salpingectomy was performed. The patient recovered well postoperatively.

Undescended ovary without abnormal development of uterus and urinary system: a report of four cases

Background Congenital anatomic abnormalities of fallopian tubes and ovaries are rarely reported. Herein, we describe four cases of undescended ovary during laparoscopic surgery with abnormal anatomy of fallopian tube, yet without abnormal uterine development and urinary system abnormalities, which are analyzed by their clinical features and effects on reproductive function. Case presentation For the patients with undescended ovary, the location of unilateral or bilateral upper poles of the ovaries were usually much higher than that of the bifurcation of the common iliac vessel, and the fallopian tubes at the same side opened in the para-colonic sulcus. Among these four patients, two patients had primary infertility, one patient had tubal pregnancy rupture and bleeding, and one patient had uterine leiomyoma. The development of uterus was normal in all cases, and there was no abnormal development of urinary system. During the infertility examination, the fact that fallopian tubes lifted up in hysterosalpingography (HSG) might be regarded as an indicator of possible undescended ovary. The pelvic ultrasonography examination was of limited use in diagnosing undescended ovary. Conclusion Laparoscopy is the gold standard for the diagnosis of undescended ovary. When there is periodic post-sacral spinal pain, MRI or HSG can be used for diagnosis of undescended ovary.

Mucociliary apparatus of the fallopian tubes and related pathogenetic aspects contributing to infertility and prospects for correction (analytical review)

Introduction. The mucociliary apparatus (MCA) of the fallopian tubes (MTр) represents one of the key mechanisms and arms in functioning of female reproductive system. A prominent role of impaired MCA in the pathogenesis of reproductive system diseases and infertility, on the one hand, as well as insufficient knowledge and elucidation of this topic, on the other hand, spurred current study.Aim: to improve our understanding about a role for reproductive system MCA and its impairment in developing diseases and infertility, as well as to identify potential perspectives for their correction.Materials and Methods. We searched for publications and analyzed literature data from 1980 to 2020 using various scientific databases, including Index Medicus, PubMed/MEDLINE, Embase, Cochrane Library and Russian scholarly journals related to gynecology, obstetrics and reproduction.Results. The analysis conducted allowed to originally assess the morpho-functional, structural-genetic features and other important aspects of MCA MTр. In addition, we demonstrated an impact of various factors on developing diverse types of pathological processes, including those capable of causing infertility. Moreover, we also elucidated a state of MCA MTр coupled to various diseases, including genetically determined disorders.Conclusion. The role of impaired MCA MTр in developing pathological process and infertility was of tremendous importance and deserves close attention, because they are often remained undiagnosed by standard methods and require use of morphological and functional research methods for verification. Perspectives for diagnostics and correction of MCA MTр disorders are further discussed.
