Background and purpose of the workshopConcern about the venous thromboembolism (VTE) risk of new hormonal contraceptive options shortly after their entry into the market has triggered a number of 'pill scares', each of which resulted in panic stopping of the formulations in question and a spike in unplanned pregnancies, yet with no subsequent reduction in VTE rates among women of reproductive age.Perhaps the best example of a recent pill scare that resulted in enormous harm from a public health perspective was the 'third-generation pill scare' that occurred in many countries in Europe and around the world in 1995. At that time the new third-generation pills were promoted as being less androgenic and as possibly having fewer adverse effects on cardiovascular and metabolic parameters and thereby potentially being safer than existing pills.Shortly after the introduction of these third-generation pills, reports of a possible increased risk of VTE began to appear. Such reports brought the progestogen component of these pills under scrutiny and inevitably a phenomenon known as 'stimulated reporting' occurred. Physicians with patients on these new pills were more likely to send their patients for assessment of any leg pain or swelling and more likely to report any VTE episodes to regulatory authorities because of heightened awareness of the possible risk. What followed was an international pill scare when regulatory authorities in a number of countries issued alerts about the possible increased risk of VTE with thirdgeneration pills. Panic stopping of pills by millions of women resulted in an abrupt and alarming rise in unplanned pregnancy as evidenced by sudden increases in deliveries and abortions, 1-3 each with their attendant increased risks of VTE.The history of this unfortunate episode is well documented. After class action lawsuits and lengthy trials, at which experts in epidemiology debated the findings, there emerged an awareness that studies examining VTE risks, in particular, required an understanding of the epidemiology of VTE and the possible biases that might systematically result in findings which diverged from the 'truth'. 4,5 The precise effects of different hormonal contraceptives on the haemostatic system continue to be studied and debated 6,7 but because compelling data for an increased risk have not been demonstrated the lawsuits were ultimately thrown out 8 and third-generation pills remain on the market and are widely prescribed today. 9 In 2009, anecdotal reports of VTE episodes in women using an ethinylestradiol/drospirenone (EE/DRSP)-based oral contraceptive (Yasmin ® ) were followed by publications with conflicting findings about the risk of VTE with this product. This led the manufacturer to invite experts in gynaecology, reproductive endocrinology, haematology and epidemiology to a workshop to critically review these recent publications to understand the reasons for divergent results and to produce a consensus statement about the likely comparative risk of this new formulation and other mar...

Introduction: This study compared healing of the scars after cesarean section during the first postpartum year using a single-or double-layer suturing technique. Scarring was assessed by a transvaginal ultrasound. We explored the appearance and localization of uterine scars with regard to the obstetric history. Our aim was to compare the position of the scar or defect, if present, its dimensions, and any residual myometrium with respect to the suturing technique during the cesarean section.Material and methods: Women with uncomplicated singleton pregnancies indicated for elective or acute cesarean section were randomly allocated to the uterine closure technique group. During the first postpartum year, their lower uterine segment was examined with a transvaginal ultrasound in three consecutive visits at 6 weeks, 6 months and 12 months.Results: 324 women attended the 12-month visit; of these, 149 underwent single-layer closure of the uterine incision and 175 double-layer technique. A higher proportion of the defects is seen in the single-layer closure technique of suturing. Defects in the single-layer group were wider (0.002) and the residual myometrial thickness in the singlelayer group were thinner (0.019). Women who underwent cesarean section at the stage of full cervical dilation had scars that were closer to the external cervical os (0.000). The position of the uterus varies greatly between controls (0.000). The combination of uterine position and scar defect presence changed significantly between controls (0.001), and was significantly dependent on the suturing method (0.003). Defects with or without contact with the uterine cavity changed statistically between controls (0.017). Both types of defects were more common in the single-layer closure technique group. Conclusions:The findings of this study demonstrate that double-layer technique with the first continuous nonlocking suture followed by a second continuous nonlocking suture is associated with better suture healing and greater residual myometrialThis is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.

Ovulatory disorders are common causes of amenorrhea, abnormal uterine bleeding and infertility and are frequent manifestations of polycystic ovary syndrome (PCOS). There are many potential causes and contributors to ovulatory dysfunction that challenge clinicians, trainees, educators, and those who perform basic, translational, clinical and epidemiological research. Similarly, therapeutic approaches to ovulatory dysfunction potentially involve a spectrum of lifestyle, psychological, medical and procedural interventions. Collaborative research, effective education and consistent clinical care remain challenged by the absence of a consensus comprehensive system for classification of these disorders. The existing and complex system, attributed to the World Health Organization (WHO), was developed more than three decades ago and did not consider more than 30 years of research into these disorders in addition to technical advances in imaging and endocrinology. This article describes the development of a new classification of ovulatory disorders performed under the aegis of the International Federation of Gynecology and Obstetrics (FIGO) and conducted using a rigorously applied Delphi process. The stakeholder organizations and individuals who participated in this process comprised specialty journals, experts at large, national, specialty obstetrical and gynecological societies, and informed lay representatives. After two face-to-face meetings and five Delphi rounds, the result is a three-level multi-tiered system. The system is applied after a preliminary assessment identifies the presence of an ovulatory disorder. The primary level of the system is based on an anatomic model (Hypothalamus, Pituitary, Ovary) that is completed with a separate category for PCOS. This core component of the system is easily remembered using the acronym HyPO-P. Each anatomic category is stratified in the second layer of the system to provide granularity for investigators, clinicians and trainees using the ‘GAIN-FIT-PIE’ mnemonic (Genetic, Autoimmune, Iatrogenic, Neoplasm; Functional, Infectious and Inflammatory, Trauma and Vascular; Physiological, Idiopathic, Endocrine). The tertiary level allows for specific diagnostic entities. It is anticipated that, if widely adopted, this system will facilitate education, clinical care and the design and interpretation of research in a fashion that better informs progress in this field. Integral to the deployment of this system is a periodic process of reevaluation and appropriate revision, reflecting an improved understanding of this collection of disorders.

Introduction: With the increasing number of caesarean sections, the number of cesarean scar pregnancies (CSP) is also increasing. This is a relatively new entity of an ectopic pregnancy, which is risky mainly because of its possible association with placenta accreta spectrum. CSP is thought to represent about 6% of the total number of ectopic pregnancies in all women who have a history of at least one caesarean section. The estimated incidence of CSP is about 1/1,688 of all pregnancies and about 1/ 2,000 of all caesarean sections. Material and methods: Retrospective analysis of individual cases of cesarean scar pregnancies managed in our health care facility in the years 2012–2021. Results: In total, we managed 16 cases of pregnancy in the caesarean scar in 15 women. In one woman, we recorded CSP twice. The mean age of the women was 36.6 years (27–41). The mean number of caesarean sections was 1.6 (1–3) and gestational week was 7 (4–10). The average time since the caesarean section was 3.6 years (2–11). The management was methotrexate administration once, hysteroscopic resection once and 11times primarily vacuum aspiration only, when in two cases we had to attach laparoscopic uterine artery ligation due to postoperative bleeding. We performed primary ligature of uterine arteries twice before performing vacuum aspiration. In pregnancies above 10 weeks of gestation, we observed more bleeding complications requiring surgical management. Bleeding complications were also related to the presence of fetal cardiac action. Conclusion: Early correct diagnosis is essential in the management of CSP. Pregnancies up to the 10th week of gestation are managed by simple vacuum aspirations under ultrasound guidance. If the pregnancy is over the 10th week of gestation and especially with cardiac activity, we add laparoscopic uterine artery ligation before vacuum aspiration. All patients are subsequently advised to undergo laparoscopic resuturing of the lower uterine segment. Key words: cesarean scar pregnancy – ultrasound – vacuum aspiration – uterine artery ligation – methotrexate
