Background: Vaginal atresia (VA) is a rare female genital tract malformation characterized by the absence or incomplete development of the vagina, often leading to cyclic abdominal pain and menstrual blood retention in adolescent patients. Vaginal atresia is often accompanied by multiple organ malformations. The condition poses significant challenges in diagnosis and management, requiring a multidisciplinary approach.

Case description: Herein, we report a case of type I congenital VA in a 13-year-old female presenting with congenital biliary atresia and urinary system malformation. Upon initial evaluation, the patient exhibited VA incision and laparoscopic excision of a left ovarian cyst under general anesthesia. By the 2-month follow-up, the patient reported normal menstrual flow without accompanying abdominal pain.

Conclusion: This case underscores the complexity of type I congenital VA concurrent with multiple organ malformations. Timely identification and proper management strategies are crucial for securing the best possible patient outcomes. Further research is warranted to elucidate the underlying mechanisms and improve treatment modalities for such cases.

Objective: To compare the subjective and objective results of laparoscopic sacrocolpopexy (LSC) with and without the introduction of a vaginal packing one year after surgery. Methodology: This is a retrospective cohort study of 125 women after laparoscopic sacrocolpopexy operated on in 2013-2016 with complete annual follow-up. Patients with a total hysterectomy were excluded from the study. Basic patient characteristics, preoperative POP-Q and surgery data were collected. The subjective outcome of the surgery was assessed using the PGI-I (patient global impression of improvement). The anatomic outcome of the surgery was evaluated using the composite definition of surgical failure based on POP-Q (Ba ≥ -1, C ≥ -3, Bp ≥ -1). Patients were divided into two groups according to whether or not they had vaginal packing after surgery. Statistical analysis was performed using c2, Wilcoxon and Fischer test according to the distribution of normality. Results: A total of 125 women were enrolled in the study; 48 (38.4%) after LSC, 58 (46.4%) with concomitant supracervical hysterectomy and 19 (15.2%) after sacrohysterocolpopexy. Vaginal packing was introduced for 24-48 hours after surgery in 86 (68.8%) women. The groups did not differ in age, body mass index, smoking or preoperative pelvic organ prolapse quantification system. We did not observe statistically significant differences in PGI-I first year after surgery. The difference in anatomic surgical failure did not reach statistical significance, although more failures were observed in the group without packing (12.8 vs. 3.5%; P = 0.09). The mean C-point value one year after surgery was lower in the non-tamponade group (-7 vs. -7.5; P < 0.009). No mesh extrusion or serious complications were recorded in the monitored group. Conclusion: Vaginal packing after LSC probably does not affect patient satisfaction after surgery, however, it may be associated with better anatomical outcome one year after the surgery. The results of the study must be confirmed by a more detailed prospective evaluation.

Objective: Copeptin is a stable fragment of vasopressin. Copeptin levels have been found to reflect the degree of endothelial stress in various conditions, including acute coronary syndrome. Copeptin may be a bio marker for endothelial stress during pregnancy. However, there is still a lack of understanding of its dynamics and levels throughout pregnancy. This study aims to describe intra-individual and longitudinal changes in copeptin levels at 30th and 36th gestational weeks in healthy pregnant women with uncomplicated pregnancy and delivery and to establish specific reference ranges.

Methods: A total of 125 pregnant women with uncomplicated pregnancy and delivery were included. These women were monitored throughout their pregnancy and gave birth at the Department of Obstetrics and Gynecology Olomouc University Hospital. The blood was taken at ~30 and ~36 gestational weeks. Serum copeptin levels were measured using a Kryptor Compact PLUS analyzer. For statistics, we used R software and the "referenceRanges" package.

Results: It was found that serum levels of copeptin were significantly higher in the 36th week group than in the 30th week group (P < 0.05). Cook's distance was used to eliminate outliers. The 30th week median was 3.377 pmol/l, reference range = 1.343-7.829 pmol/l, and the 36 week was median 4.735 pmol/l and reference range = 2.06-13.2 pmol/l. In the 36th week reference range, the median was higher than in healthy, non-pregnant women (P < 0.05). Copeptin values can exceed 10 pmol/l, particularly after the 36th week. In the 3rd trimester, this value may indicate cardiovascular and endothelial overload.

Conclusion: Copeptin levels were found to vary significantly depending on gestational week. The proposed reference ranges take into account the increased secretion of vasopressin in pregnancy. The existence of specific upper reference limits represents a potential advantage in detecting pregnant women prone to hypertensive disease in the 3rd trimester.

Estrogens are key hormones that play a vital role in the physiology of the reproductive system in women. However, their therapeutic use in hormonal treatment, contraception, and the treatment of hormone-dependent diseases may be associated with a number of side effects, especially on the liver. This article focuses on the mechanisms of action of estrogens and their potential hepatotoxic effects, as well as risk factors and possible differences between representatives.

Objective: To present a case of acute haemorrhagic stroke during 3rd trimester of pregnancy and to describe management and successful delivery of healthy baby.

Case report: Haemorrhagic stroke is responsible for significant morbidity and mortality. Prognosis can be improved only by urgent diagnosis and care. We report a case of pregnant woman at 37th week of pregnancy with acute haemorrhagic stroke of unknown etiology with clinical appearance of thunderclap headaches and overall disorientation. We describe diagnostic approach and a successful management followed by further differential diagnosis and treatment. The foetus was delivered by acute caesarean section at 37th week of pregnancy.

Conclusion: Occurrence of haemorrhagic stroke in pregnancy is rare. There are no specific guidelines that recommend the time and mode of delivery; therefore, each case is assessed individually.

The human placenta serves as a vital barrier between the mother and the developing fetus during pregnancy. A defect in the early development of the placenta is associated with severe pregnancy disorders. Despite its complex development, various molecular processes control placental development, and the specialization of trophoblast cells is still not fully understood. One primary obstacle is the lack of suitable cell model systems. Traditional two-dimensional (2D) cell cultures fail to mimic in vivo conditions and do not capture the intricate intercellular interactions vital for studying placental development. However, three-dimensional (3D) organoid models derived from stem cells that replicate natural cell organization and architecture have greatly improved our understanding of trophoblast behavior and its medicinal applications. Organoids with relevant phenotypes provide a valuable platform to model both placental physiology and pathology, including the modeling of placental disorders. They hold great promise for personalized medicine, improved diagnostics, and the evaluation of pharmaceutical drug efficacy and safety. This article provides a concise overview of trophoblast stem cells, trophoblast invasion, and the evolving role of organoids in gynecology.

Objective: To analyze the main indications for induction of labor with vaginal misoprostol in high-risk pregnancies as well as the main variables associated with failed induction in a tertiary center in the metropolitan region of Rio de Janeiro, Brazil.

Methods: A retrospective cohort study analyzed the medical records of pregnant women who underwent induction of labor. Inclusion criteria were singleton pregnancy, gestational age ≥ 34 weeks, Bishop score ≤ 6, fetuses in cephalic presentation, and no contraindications for the use of vaginal misoprostol. The labor induction protocol consisted of vaginal misoprostol 25 mcg every 6 hours, with a maximum of eight doses (200 mcg) to ripen the cervix if Bishop's score was ≤ 6.

Results: A total of 88 cases of labor induction were analyzed. Main indications for labor induction were preeclampsia and gestational hypertension (N = 28; 31.8%), chronic arterial hypertension (N = 19; 21.6%), and gestational diabetes mellitus (N = 12; 13.6%). We observed that vaginal delivery was associated with the number of vaginal misoprostol doses (P = 0.000348). The most common indications for cesarean section were failure of labor induction (N = 21; 40%) and suspected acute fetal distress (N = 17; 33%). We did not observe a statistical difference between indication of labor induction and mode of delivery. There were no fetal deaths. Six neonates were admitted to the neonatal intensive care unit (NICU), one for respiratory distress, one for preterm delivery, and four for hypoglycemia. There was no statistical difference in the rate of NICU admission between delivery modes (P = 0.692).

Conclusion: The main indication for cesarean section in this study was induction failure, indicating the need to review and continuously monitor the protocol to increase success rates without compromising perinatal outcomes.

Most bone tumors are metastatic. Breasts, lungs, kidneys, and thyroid are the primary sites most commonly involved in bone metastasis-type outcomes. This case study describes the involvement of a patient with a bone tumor located in the axial skeleton, initially in the sacral region. However, the primary site was undefined. Therefore, it was necessary to expand the investigation with immunohistochemistry, which demonstrated a metastatic tumor compatible with endometrioid adenocarcinoma. But even after examination, no active lesion was found in the endometrial region. The study was observational, descriptive, and aimed to discuss the importance of more specific investigative methods. In this context, immunohistochemistry stands out as an exquisite method capable of optimizing diagnosis, therapy, and consequently, prognosis.

The authors present a case of 1st trimester miscarriage where an early, complete hydatidiform mole was clinically suspected. Histopathological and immunohistochemical analyses excluded a complete mole, but the histomorphological profile was in concordance with a partial hydatidiform mole. Genetic analysis excluded a partial mole based on biparental genome composition, where further genetic analyses detected trisomy of chromosome 16. Trisomy of chromosome 16 is a frequent cause of 1st trimester abortions and may lead to highly abnormal placental histomorphology mimicking a partial mole. Genetic analyses are crucial for proper differential diagnosis and for the determination of adequate follow-up and prognosis for further pregnancies.

Endometrial cancer is the most common gynecological cancer and the second most prevalent female malignancy in the developed world. It is typically diagnosed in postmenopausal women, presenting with the characteristic clinical symptom of uterine abnormal bleeding. In the past, only two histological types were considered. However, it has become increasingly evident that endometrial cancer is a clinically heterogeneous disease, and this heterogeneity is closely associated with the diversity of underlying molecular alterations. The Cancer Genome Atlas classification has significantly advanced the diagnosis, risk stratification, and management of endometrial cancer by categorizing it into four molecular subgroups, each characterized by distinct mutational burdens and copy number alterations.
