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.

Objective: Presentation of acute retrobulbar subperiostal hemorrhage (hematoma) in the course of delivery. The occurrence, possible threats and recommended methods of treatment are described. Introduction: Acute retrobulbar hemorrhage is always a serious condition. Even if not connected with other ocular trauma, it could cause permanent blindness. The reason is based on constriction of the eye, decreasing of the blood supply and thus disruption of the oxygen supply to sensitive retinal tissues. After a short time, these tissues start to deteriorate and lose their natural function. This event is often connected with exophthalmia and diplopia. The primary diagnostic procedure is to measure intraocular pressure (IOP). Even if the ideal diagnostic tools are not accessible, performing a lateral canthotomy (event. with inferior cantholysis) is recommended to relieve IOP in acute situations. Normal intraocular pressure is considered to be 8-21 mmHg. Case report: Our 29-year-old female patient was in the second stage of delivery and suddenly got retrobulbar hemorrhage, resulting in exophthalmia and diplopia. Her baby was delivered shortly after the event. The following delivery course was normal, including her perineum repair and puerperium. Our patient was fortunate because her visual acuity and IOP were normal. Therefore, we chose an observational treatment strategy. After 5 weeks, we noted successful disintegration of the hematoma and decreased exophthalmia and diplopia without other consequences. Conclusion: We described retrobulbar subperiostal bleeding in our patient in the course of delivery. We depicted possible threats that could result in blindness and described recommended methods of treatment. Even if such a situation is extremely rarely, we believe that knowledge of these guidelines could help medical professionals broaden their treatment options. This particularly occurs when a trained eye surgeon is not available.

Aim: Aim of the study to summarize the current information on diagnostic and treatment options for uterovesical fistula as a consequence of iatrogenic complication. Methods: Literature review of available information on surgical treatment options for uterovesical fistula resulting from previous caesarean section and comparison with our own experience in the developing world. Conclusion: Uterovesical fistula is an abnormal communication between the bladder and uterus. The cause of this pathology in most cases is an iatrogenic complication, most commonly arising after a caesarean section. The incidence of this pathology varies significantly geographically. In developed countries, these fistulas are rather rare. On the other hand, in developing countries, uterovesical fistulas are more common with a significant impact on the subsequent life of the patient due to generally inaccessible health care.

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.

Endometriosis is a chronic disease characterised by the presence of endometrial tissue outside the uterine cavity, affecting 5-15% of women, especially those of reproductive age. The disease may manifest itself as dysmenorrhoea, dyspareunia, sterility and chronic pelvic pain, among other symptoms. Although it is not malignant, it shares some characteristics with cancer and can lead to epithelial ovarian carcinoma. The risk of malignant transformation of endometriosis is estimated at 1% in premenopausal women and 1-2.5% in postmenopausal women. Our case report describes a 46-year-old female patient with long-standing abdominal pain and a history of surgically confirmed endometriosis. Imaging revealed a cystic mass in the left mesogastrium, which was subsequently surgically removed. Histological examination confirmed the presence of a low-grade endometrioid carcinoma arising from an extragenital endometriosis lesion. Following surgical treatment, the patient underwent adjuvant chemotherapy, after which she was in complete remission. The diagnosis of malignant transformation of endometriosis is complex, requiring a combination of thorough clinical examination, imaging, and histopathological verification. Therapy involves radical surgery and possibly adjuvant chemotherapy, similar to ovarian carcinomas. Despite advances in treatment and research, endometriosis remains a complex disease with unclear aetiology, heterogeneous clinical presentation, and risk of malignant transformation.

Objective: The objective of this study was to evaluate the Pap smear and colposcopy findings in female inmates in a prison unit in the state of São Paulo, Brazil.

Methods: A retrospective cross-sectional study was carried out by analyzing the Pap smear and colposcopy examinations of female inmates in a prison unit. The following socio-demographic data were assessed: age, nationality, level of education, marital status, height, weight, ethnicity, occupation, religion, sexual orientation, and presence of tattoos.

Results: The sample consisted of 894 women who had a Pap smear, the majority of whom were Brazilian (93.6%), 41.1% had an incomplete primary education, 58.5% were single, 50.1% were white, 60.7% had tattoos, and the predominant religion was Catholicism at 42.8%. Regarding sexual orientation, 124 (13.9%) women identified as bisexual, 640 (71.6%) as heterosexual, and 127 (14.2%) as homosexual. Most Pap smears showed benign findings (86.5%). Of the female inmates who had a Pap smear, 121 (13.5%) were referred for colposcopy. Altered colposcopy findings occurred in 95 (10.6%), with the most common findings being high-grade squamous intraepithelial lesions 36 (4.0%) and low-grade squamous intraepithelial lesions 27 (3.0%). The majority of women (96.0%) had no clinical signs of human papillomavirus - HPV (anogenital verrucous lesions) and only 36 (4.0%) had lesions suggestive of HPV on Pap smears. There were more HIV cases in the group with HPV verrucous lesions (P = 0.013).

Conclusion: We observed 13.5% and 78.5% of abnormal findings in Pap smears and colposcopy, resp.), in female inmates in a prison unit in the state of São Paulo, Brazil.

Objective: To investigate DNA methylation of specific tumor suppressor genes in endometrial hyperplasia compared to normal endometrial tissue. File and methodology: To search for epigenetic events, methylation-specific multiplex ligation-dependent probe amplification was employed to compare the methylation status of 40 tissue samples with atypical endometrial hyperplasia, 40 tissue samples with endometrial hyperplasia without atypia, and 40 control tissue samples with a normal endometrium.

Results and conclusion: Differences in DNA methylation among the groups were found in TWIST1, GATA4, MUS81, and NTRK1 genes (TWIST1: atypical hyperplasia 67.5%, benign hyperplasia 2.5%, normal endometrium 22.5%; P < 0.00001; GATA4: atypical hyperplasia 95%, benign hyperplasia 65%, normal endometrium 22.5%; P < 0.00001; MUS81: atypical hyperplasia 57.5%, benign hyperplasia 22.5%, normal endometrium 5%; P < 0.00001; NTRK1: atypical hyperplasia 65%, benign hyperplasia 27.5%, normal endometrium 10%; P < 0.00001). Higher methylation rates were observed for the tumor suppressor genes of TWIST1, GATA4, MUS81, and NTRK1 in samples with atypical endometrial hyperplasia compared to samples with normal endometrial tissue, and higher methylation rates were found in samples with atypical endometrial hyperplasia compared to samples of benign endometrial hyperplasia. DNA methylation of TWIST1, GATA4, MUS81, and NTRK1 is involved in the pathogenesis of atypical endometrial hyperplasia.

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.

Aim: The aim of this study is to compare the extent of ovarian endometriosis diagnosed at preoperative staging with subsequent perioperative findings. Definition of discrepancies observed according to the #Enzian 2021 classification.

Material and methods: The cohort includes 62 patients of reproductive age with preoperative findings of ovarian endometrioma. Patients were divided according to the #Enzian 2021 classification into subgroups (O1, O2 + O3) with unilateral and bilateral findings. The percentage concordance of preoperative and perioperative findings was evaluated.

Results: In the evaluation of ovarian involvement, the preoperative ultrasound diagnosis shows almost 100% agreement with the findings on the ovaries during surgery. Periadnexal adhesions were predicted preoperatively in only half of the cases. The difference in laterality was confirmed with T3 involvement in the O2 + O3 subgroup. In the bilateral involvement, the finding of the presence of grade 3 adhesions was doubled. An association of ovarian form of endometriosis (O2-O3) with deep infiltrating endometriosis of the small pelvis was observed in 50% of the cohort.

Conclusion: The ovarian form of endometriosis is associated with the occurrence of other endometriosis lesions in the small pelvis. In this study, it was confirmed that preoperative staging underestimates the extent of endometriosis in the small pelvis. In the surgical management of ovarian endometriosis, extensive adhesive process should be expected.
