Diagnosis of infertility from adenomyosis and endometriosis through entroxon based intelligent water drop back propagation neural networks

Adenomyosis is an abnormality in the uterine wall of women that adversely affects their normal life style. If not treated properly, it may lead to severe health issues. The symptoms of adenomyosis are identified from MRI images. It is a gynaecological disease that may lead to infertility. The presence of red dots in the uterus is the major symptom of adenomyosis. The difference in the extent of these red dots extracted from MRI images shows how significant the deviation from normality is. Thus, we proposed an entroxon-based bio-inspired intelligent water drop back-propagation neural network (BIWDNN) model to discover the probability of infertility being caused by adenomyosis and endometriosis. First, vital features from the images are extracted and segmented, and then they are classified using the fuzzy C-means clustering algorithm. The extracted features are then attributed and compared with a normal person’s extracted attributes. The proposed BIWDNN model is evaluated using training and testing datasets and the predictions are estimated using the testing dataset. The proposed model produces an improved diagnostic precision rate on infertility.

Uterine Embolization as a New Treatment Option in Adenomyosis Uteri

Adenomyosis is characterized by the development of endometrial ectopic glands and tissue in the myometrium layer in depth greater than 2.5 mm from the endometrial surface of the separative area by -myomas well as by hypertrophy and hyperplasia of the smooth muscles of the myometrium. This is filtration, not mere displacement, of the myometrium, from the endometrium. Clinical symptoms include dysmenorrhea and menorrhagia. It is diffuse (adenomyosis) or focal (adenomyoma), asymmetrically affects the uterine wall of premenopausal women (usually the posterior) and often coexists with myomas. The pathogenesis of adenomyosis remains unknown. The treatment options are: drug therapy, invasive treatment of fibroids: myomectomy (open—intra-abdominal, laparoscopic, hysteroscopic), hysterectomy, myolysis—cryocatalysis, microwave or radiofrequency thermal catalysis (RF-ablation), ultrasound focus catalysis (FUS), laser photocatalysis and percutaneous selective uterine artery embolization (UAE). Embolization remains an alternative and not a substitute of hysterectomy. The medical indication is made on a case-by-case basis, depending on age, desire for pregnancy and the clinical symptoms of adenomyosis.

Laparoscopic management of a full-thickness uterine niche with subsequent pregnancy outcome

Background: Uterine niche is the consequence of impaired healing of the myometrium following a lower segment transverse caesarean section (CS). Although there is conflicting evidence on the management of these cases, laparoscopic repair is a commonly used surgical treatment modality. Objectives: To demonstrate the management and laparoscopic repair of the niche with subsequent pregnancy outcome. Materials and Methods: We report a case of a 33-year-old patient who had a significant haematoma in the niche. The haematoma resolved after conservative management however, she remained symptomatic. Therefore, she had a laparoscopic repair. The narrated surgical video article demonstrates the dissection of the uterovesical fold overlying the niche, followed by the excision of the scar tissue and its repair with laparoscopic suturing. Ultrasound and magnetic resonance imaging images of the uterus demonstrating the haematoma at the caesarean section site, the niche after resolution of the haematoma and post-repair imaging are also provided. Main outcome measures: Repair of the niche, symptomatic relief of abnormal uterine bleeding, spontaneous conception and live birth. Ultrasonographic images also demonstrate uterine wall continuity post laparoscopic repair. Results: The patient recovered uneventfully. Full-thickness of myometrium was demonstrated with post-operative imaging and confirmed at the subsequent caesarean section. Gynaecological symptoms resolved following the repair. The patient conceived spontaneously after surgery and delivered at term by caesarean section without any complications. Conclusion: Laparoscopic management of the niche should be considered where there is a complete myometrial defect or significant thinning of the myometrium, especially in symptomatic women who desire future pregnancy.

Soluble FMS-Like Tyrosine Kinase-1: Role in placenta accreta spectrum disorder

Background: Placenta accreta is a pregnancy condition where the placenta's blood vessels attach too deeply to the uterine wall. Incidence of placenta accreta is increasingly seen today as the rate of cesarean section increases, however, the exact pathophysiology of this condition is still not fully understood. Soluble fms-like tyrosine kinase-1 (sflt-1) as a protein produced by the placenta was found to be decreased in placenta accreta, Therefore we aim to see if sfltsFlt-1 has a role in the development of placenta accreta. Methods: This study involved 40 samples from patients that had been diagnosed with placenta accreta spectrum disorder (case group), and 40 samples from patients with normal pregnancies (control group) at Rumah Skit Umum Pusat H.Adam Malik (RSUP) Haji Adam Malik Medan, in Indonesia. Diagnosis of placenta accreta syndrome was based on Placenta Accreta Spectrum Score (PAS), and International Federation of Gynecology and Obstetrics (FIGO) classification of placenta accreta spectrum disorder.Analyses were performed by independent t-test, man Mann-Whitney U test, and Kruskal-Wallis analysis test, with a P-value <0.05 considered as statistically significant (95%CI). Results: Based on this study, we found that the sFlt-1 level in the case group was lower than the control group. Data analysis using the Kruskal-Wallis test showed that there was a difference in sFlt-1 levels in this study group (p = 0.02), which was further evaluated with post hoc analysis using Mann. -Whitney U test. The results indicated that there were significant differences between the control and PAS 0, PAS1, and PAS 2 (p = 0.043; p = 0.002; p = 0.03). Conclusion: sFlt-1 levels decreased in placental invasive pregnancies compared to normal pregnancies, however, this still needs to be investigated further in a multi-center study, considering that sFlt-1 levels are also influenced by ethnicity and other conditions that cannot be excluded in this study.

Clinical case of expectant tactics of scar pregnancy and childbirth in the III trimester

One of the rare complications of a previous cesarean section is pregnancy with implantation in the area of the postoperative scar. The literature describes isolated reports of this pathology, which relate to early pregnancy. The forecast and tactics of their management are debatable issues.This article presents a case of successful monitoring of pregnancy and childbirth of a patient with a combined pathology: the placenta in the area of the cesarean scar with its diastase and central placenta previa with the germination of the uterine wall.The 34-year-old pregnant woman (III pregnancy and II expected childbirth) during ultrasound examination central a placenta previa was diagnosed. It had ingrowth into the uterine wall creating defect of the cesarean scar. Informed about the possible risks, patient strongly insisted on prolonging the pregnancy. Since 23 weeks she was in an obstetric hospital for the possibility of urgent surgery. Within 37 weeks, a planned caesarean section was performed by bottom access with subsequent extirpation of the uterus. Literary data from different countries almost all describe the completion of cesarean scar pregnancy in the first and second trimesters. Due to the rarity, heterogeneity of groups and the lack of a single protocol for the management of this pathology, combined or modified approaches to treatment are more often used. Primary prevention should begin at the stage of preventing a high frequency of cesarean section, reviewing the indications for it and conducting a truly justified surgery. Preconceprion care should be mandatory when planning the next pregnancy. Great attention should be paid to the localization of the chorion in the protocol of the screening ultrasound examination of the first trimester if there is uterine scar. In the case of a cesarean scar pregnancy, we cannot recommend an expectant tactics at this stage. Any method that eliminates cesarean scar pregnancy, especially in the early term, will saving the body and future fertility, as well as reduces morbidity and mortality.

Placenta Percreta Presents with Neoangiogenesis of Arteries with Von Willebrand Factor-Negative Endothelium

In placenta percreta cases, large vessels are present on the precrete surface area. As these vessels are not found in normal placentation, we examined their histological structure for features that might explain the pathogenesis of neoangiogenesis induced by placenta accreta spectrum disorders (PAS). In two patients with placenta percreta (FIGO grade 3a) of the anterior uterine wall, one strikingly large vessel of 2 cm length was excised. The samples were formalin fixed and paraffin-embedded. Gomori trichrome staining was used to evaluate the muscular layers and Weigert-Van Gieson staining for elastic fibers. Immunohistochemical staining of the vessel endothelium was performed for Von Willebrand factor (VWF), platelet endothelial cell adhesion molecule (CD31), Ephrin B2, and EPH receptor B4. The structure of the vessel walls appeared artery-like. The vessel of patient one further exhibited an unorderly muscular layer and a lack of elastic laminae, whereas these features appeared normal in the vessel of the other patient. The endothelium of both vessels stained VWF-negative and CD31-positive. In conclusion, this study showed VWF-negative vessel endothelia of epiplacental arteries in placenta accreta spectrum. VWF is known to regulate artery formation, as the absence of VWF has been shown to cause enhanced vascularization. Therefore, we suppose that PAS provokes increased vascularization through suppression of VWF. This process might be associated with the immature vessel architecture as found in one of the vessels and Ephrin B2 and EPH receptor B4 negativity of both artery-like vessels. The underlying pathomechanism needs to be evaluated in a greater set of patients.

Ovarian physiology of repeat breeder cows at Bathan area of Bangladesh

The experiment was implemented at farmer’s house and Bathan areas of Shahjadpur Upazila in Sirajganj and Bera Upazila under Pabna districts of Bangladesh. The aim of the study was to know the incidence of repeat breeding (RB), physiology of different follicles and deformity of ovary and uterus in Holstein Frisian (HF) cows. Forty (40) RB HF cows (>50% HF Genetic) were selected on the basis of age and parity. Pyometra, endo-metra, cervicitis, Salpingitis and tumor like growth etc. in uterine wall were observed. Luteal and follicular cyst was also identified. Number of growing follicle appeared ultrasonically, size of Graafian follicle, breed, cow’s body size, and inheritance level and parity, nutritional factors and days calving to first service were recorded properly. All collected data were statistically analyzed by the SPSS soft-ware program using completely randomized design (CRD). Results revealed that, significantly (P<0.05) highest Body Condition Score (BCS) was 3.47±0.05 observed in the cows of group-D whose age were more than 8 years of old compared to others group (table 1). In-case of average daily milk yield and remained dry condition differences were highly significant (P<0.001). Maximum milk yield (20.41±0.82 l/day) was observed in group-C compared to others group but minimum dry condition remaining period was observed in group-A than others. Days of heat showed number of AI service were non-significant (P>0.05) in the whole experiment (table-1). The percentage of infection (Pyometra, Endometra) in the uterine wall differed non-significantly (P>0.05) among all the groups and minimum occurrence were observed in group-A (figure 1). Highest percent of cyst observed in the right ovary than left of the cows of group-D compared to others group but the differences were non-significant (P>0.05).Comparatively higher percentage (58.82±12.30) of follicles observed in left ovary of group-D than right ovary of others group (table 3). Non-significantly (P>0.05) the highest average number (2.40±0.44) of follicles was observed in left ovary of the group-C than the cows of others group. Though the follicle size in the end of luteal phase differed non-significantly (P>0.05) but comparatively larger (14.90±1.54mm) follicle in diameter were observed in group-C, than the follicles of others groups.

Frontal tangential coronal view two-dimensional ultrasonography in assessment of fetal face [mouth and nose] in comparison with four-dimensional ultrasonography

Background The fetal face reflects strictly the development of the fetal brain during its growth. Four-dimensional (4D) examination permits continuous monitoring of the examined parts of fetal face and surface. The final performance of obstetric sonographic images depends upon multiple factors, such as fetal lie, uterine wall, abdominal wall fat, amniotic fluid, and the number of gestations which may limit the optimum performance of (4D) ultrasound. The two-dimensional (2D) ultrasound is the first choice due to its wide availability, low cost, and real-time capabilities. The tangential view obtained by (2D) ultrasound coronal sections through the face showed the nose, nostril, lips, eye, lens, and hard palate. Results One hundred and sixty fetuses showed straight forwards obstetric examination by both 2D and 4D examinations with identical final reports. While the total number of fetuses with clear images by 2D frontal tangential coronal examination was 191 cases, only 29 cases failed, whereas 170 cases obtained clear images by 4D examination, and 50 cases failed. Both 2D and 4D ultrasound failed to obtain clear images of 19 cases, while 4D failed for 31 cases, and 2D failed for 10 cases. 2D imaging was found to be significantly better than 4D imaging, with a P value of 0.009. Conclusion 2D ultrasound using the frontal tangential coronal view is an essential part of the fetal examination and more superior than 4D ultrasound in assessing facial anatomy and anomalies, as well comparable to 4D ultrasound as regards fascial expression.
