RESUMO

AIM: Colposcopic indexes including Reid index and Swede score were developed to make the colposcopy more objective. The aim of our study was to evaluate the significance of colposcopic indexes in the evaluation of ASC-H cervical lesions. METHODS: We carried out a cross-sectional study in the Clinic of Obstetrics and Gynecology between January 2013 and December 2018. The study included 535 women, from which 66 women had a cytological result ASC-H. Scoring of all colposcopic findings was assessed according to Reid modified index and Swede score and a composite score was determined. Frequency distributions were compared using χ2 /Fisher exact test. Spearman rank correlation coefficient was computed between RCI and Swede score. RESULTS: Sensitivity, specificity, positive and negative predictive value and positive likelihood ratio of modified Reid colposcopic index at a cutoff of ≥4 for the detection of HSIL+ lesions were: 86.11% (95% CI: 70.5-95.3), 83.33% (95% CI: 65.3-94.4), 86.11% (95% CI: 69.7-94.8), 83.33% (95% CI: 64.5-93.7) and 5.17 (95% CI: 2.3-11.6). Swede score with the cutoff value ≥5 showed comparable results to modified Reid index with the increased sensitivity: 94.44% (95% CI: 81.3-99.3). CONCLUSION: ASC-H category represents the trickiest cytological diagnosis as it is underlined with the high risk of severe cervical dysplasia. Evaluating the cervical lesion by the use of colposcopic indices helps the gynecologist to objectively evaluate all the pathologies of uterine cervix. Swede score with the cutoff value 8 also enables a 'see and treat' option in management of atypical squamous cells, cannot exclude high-grade lesions.

RESUMO

Metastatic breast cancer is characterized by aggressive spreading to distant organs. Despite huge multilevel research, there are still several important challenges that have to be clarified in the management of this disease. Therefore, recent investigations have implemented a modern, multiomic approach with the aim of identifying specific biomarkers for not only early detection but also to predict treatment responses and metastatic spread. Specific attention is paid to short miRNAs, which regulate gene expression at the post-transcriptional level. Aberrant miRNA expression could initiate cancer development, cell proliferation, invasion, migration, metastatic spread or drug resistance. An miRNA signature is, therefore, believed to be a promising biomarker and prediction tool that could be utilized in all phases of carcinogenesis. This article offers comprehensive information about miRNA profiles useful for diagnostic and treatment purposes that may sufficiently advance breast cancer management and improve individual outcomes in the near future.

RESUMO

Endometrial cancer is the most commonly diagnosed gynecological cancer and its incidence is increasing worldwide. The number of patients with this disease is likely to continue to grow, including younger patients. It is a complex disease driven by abnormal genetic and epigenetic alterations, as well as environmental factors. Many endometrial cancers show estrogen-dependent proliferation. The carcinogenic mechanisms are unknown or not completely explained beyond mutations of single oncogenes and tumor suppressor genes. Possible carcinogenic mechanisms include imbalance between endometrial proliferation by unopposed estrogen and the mismatch repair (MMR) system; rmethylation changes and mutation of genes. Epigenetic changes resulting in aberrant gene expression are dynamic and modifiable features of many cancer types. A significant epigenetic change is aberrant DNA methylation. In this review, we review evidence on the role of different changes in relation to endometrial carcinogenesis. Carcinogenic mechanisms of endometrial cancer involve both genetic and epigenetic changes. Determination of the detailed carcinogenic mechanisms will be useful for prevention and diagnosis of endometrial cancer, risk assessment, and development of new treatment strategies targeting genes.

RESUMO

BACKGROUND: Postpartum hemorrhage (PPH) represents a serious problem for women and obstetricians. Because of its association with hemorrhagic shock and predisposition to disseminated coagulopathy, it is a leading cause of maternal deaths worldwide. Furthermore, the jeopardy of PPH is rising with the secondary form of PPH occurring between 24 hours and 6 weeks postpartum, when women are already discharged home. The causes of this pathology are severe inflammation (endometritis), inherited coagulation disorders, consumptive coagulopathy, and retained products of conceptions. Others are of rare occurrence, such as vessel subinvolution (VSI) of the placental implantation site, uterine artery pseudoaneurysm, or trauma. CASE PRESENTATION: We present a rare form of recurrent secondary postpartum hemorrhage in a woman after uncomplicated cesarean delivery, with review of the literature linked to the management of this situation originating in the rare local VSI in the placental implantation site, defective decidual homeostasis, and coagulopathy confined to the uterus. CONCLUSION: The placental site VSI is one of the rare causes of secondary PPH, and this situation is frequently underdiagnosed by clinicians. The histological confirmation of dilated "clustered"-shaped myometrial arteries partially occluded by thrombi of variable "age" together with the presence of endovascular extravillous trophoblasts confirms the diagnosis.

RESUMO

OBJECTIVE: Ultrasonographic evaluation of the postpartum uterus to prevent retained placental tissue complications is still a matter of debate, and it is difficult to interpret its necessity on the basis of previous studies. We hypothesized that the application of uterotonics on the basis of regular postpartum ultrasound scanning of the uterus may reduce the number of unnecessary curettages in a large unselected population. METHODS: This was a cross-sectional observational study conducted among mothers (n = 6,028) delivering at two different (secondary and tertiary) hospitals to analyze the benefit of postpartum uterine ultrasound for clinical implications. Women delivering at the secondary care unit (n = 1,915) had no regular postpartum ultrasound scans in comparison to those delivering at the tertiary unit (n = 4,113). On regular ultrasound scans, morphological findings in the uterine cavity were recorded. Upon the presence of an intrauterine hyperechogenic mass larger than 2 cm in diameter, mothers received a single dose of uterotonics (methylergometrin 0.2 mg or oxytocin 5 IU) intramuscularly and control sonography after 24 h. In case of intrauterine mass persistence and serious postpartum hemorrhage women underwent a surgical intervention. The management was similar at the secondary unit, but ultrasound scans were provided only when there was a clinical finding. All patients were followed-up 6 weeks after labor. RESULTS: Women delivering at the secondary institution experienced a higher incidence of puerperal surgical interventions (1.51 vs. 0.87%) and lower agreement between sonography and histological findings (72.4 vs. 86.1%) compared with women delivering at the tertiary care unit, respectively (P < 0.05), where the general incidence of interventions was 1.10% after spontaneous and 0.19% after cesarean deliveries. In addition, trained sonographers reached only 13.9% false-positive ultrasound scans. Time-dependent regression analysis of uterine morphological involution variables showed a significant association between uterine length, width, uterine cavity and cervical channel mass, P < 0.0001, P < 0.01, P < 0.05, P < 0.05, respectively, and insignificant association between uterine cavity volume with an increased time period postpartum. CONCLUSIONS: In this study, routine ultrasound evaluation of the uterus in the postpartum period with regular application of uterotonics decreased the rate of surgical interventions. We strongly advise the introduction of postpartum uterine scanning into obstetrical practice, most suitably provided around day 3 after delivery.

RESUMO

Malignancies are one of the leading causes of mortality in women during their reproductive life. Treatment of gynecological malignant tumors during pregnancy is possible but not simple, since it creates a conflict between care of the mother and the fetus. BC is the most prevalent malignancy diagnosed in pregnancy, ranking up to 21% of all pregnancy-related malignancies. Due to its stets increasing prevalence, aggressive cancer subtype, and severe ethical and psychological aspects linked to the disease, experts raise an alarm for an acute necessity to improve the overall management of the PABC-the issue which has strongly motivated our current paper. Comprehensive research data and clinical experience accumulated in recent years have advanced our understanding of the disease complexity. PABC treatment must be individualized with an emphasis on optimal care of the mother, while observing standard treatment protocols with regard to safety of the fetus. Treatment protocols should be elaborated based on the individualized patient profile, bearing in mind the acute danger to the mother, maximizing the therapy efficacy and minimizing harmful effects to the fetus. Complex consulting on treatment options, their impacts on pregnancy and potential teratogenic effects requires tight "doctor-patient" collaboration. Complications that may arise due to the treatment of breast cancer in pregnancy require a multiprofessional expertise including oncologists, neonatologists, perinatologists, obstetricians, teratologists, and toxicologists, and an extensive psychological support throughout the pregnancy and after giving birth. Thereby, specifically psychological aspects of PABC diagnosis and follow-up are frequently neglected, being not yet adequately explored in the entire disease management approach. Herewith, we update the status quo regarding the currently available diagnostic modalities, complex treatment algorithms, and novel clinical approaches which altogether argue for an urgent necessity of a paradigm shift moving away from reactive to predictive, preventive, and personalized medical approach in the overall management of PABC meeting the needs of young populations, persons at high risk, affected patients, and families as the society at large.
