Electrosurgery: heating, sparking and electrical arcs.

The translation of impedance (R), current (I), and voltage (V) into tissue effects and the understanding of the settings of electrosurgical units is not obvious if judged by the many questions during live surgery. Below 200 V, the current heats the tissue until the steam of boiling stops the current. Thus, slower heating, because of less energy or a larger contact area, results in deeper coagulation.

Diagnostic Value of Autoantibodies against Steroidogenic Enzymes and Hormones in Infertile Women with Premature Ovarian Insufficiency.

The objective of the study was to evaluate the profile and diagnostic significance of serum autoantibodies in infertile patients with premature ovarian insufficiency (POI). The pilot study included 26 patients of reproductive age with POI and diminished ovarian reserve who received complex treatment using new surgical technologies (Group 1) and 18 patients without POI (Group 2). The profile of serum autoantibodies, including anti-ovarian antibodies, antibodies against thyroid peroxidase (TPO), steroidogenic enzymes, and steroid and gonadotropic hormones, was studied using modified ELISAs and human recombinant steroidogenic enzymes (CYP11A1, CYP19A1, CYP21A2).

A systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses 2020 checklist. Registration number: CRD42022354697.

Altered Glycolysis, Mitochondrial Biogenesis, Autophagy and Apoptosis in Peritoneal Endometriosis in Adolescents.

Energy metabolism plays a pivotal role in the pathogenesis of endometriosis. For the initial stages of the disease in adolescents, this aspect remains unexplored. The objective of this paper was to analyze the association of cellular and endosomal profiles of markers of glycolysis, mitochondrial biogenesis, apoptosis, autophagy and estrogen signaling in peritoneal endometriosis (PE) in adolescents.

Metformin and progestins in women with atypical hyperplasia or endometrial cancer: systematic review and meta-analysis.

Purpose: To assess metformin's effectiveness in adding it to progestin-based hormone therapy for treating atypical endometrial hyperplasia (AEH) and early endometrial cancer (EEC).

Methods: We conducted a systematic review and meta-analysis following PRISMA guidelines (registration number CRD42023399094). We searched databases for studies up to March 2023, including randomized and non-randomized clinical trials in English.

Novel Approaches to Possible Targeted Therapies and Prophylaxis of Uterine Fibroids.

Uterine leiomyomas are the most common benign tumors in women of childbearing age. They may lead to problems of conception or complications during the gestational period. The methods of treatment include surgical (myomectomy and hysterectomy, embolization of arteries) and therapeutic treatment (ulipristal acetate, leuprolide acetate, cetrorelix, goserelin, mifepristone).

The 10 "Cardinal Sins" in the Clinical Diagnosis and Treatment of Endometriosis: A Bayesian Approach.

Evidence-based data for endometriosis management are limited. Experiments are excluded without adequate animal models. Data are limited to symptomatic women and occasional observations.

Predictive Value of Ultrasound Imaging for Diagnosis and Surgery of Deep Endometriosis: A Systematic Review.

Objective: To calculate the predictive value and thus the clinical usefulness of transvaginal ultrasound (US) imaging for the management of deep endometriosis, knowing that the positive predictive value (PPV) varies with the prevalence and probably with the volume and location of the disease.

Data Sources: After registration on PROSPERO (CRD42022366323), PubMed was searched for all reports describing the diagnostic accuracy of US imaging for deep endometriosis published between January 1, 2000, and October 20, 2022.

Methods Of Study Selection: The 536 articles on "endometriosis AND US And diagnosis" were hand searched, and 30 reports describing sensitivity and specificity of deep endometriosis were found.

Endometriosis in Adolescents: Diagnostics, Clinical and Laparoscopic Features.

Background: The early diagnosis of endometriosis in adolescents is not developed.

Objective: We aim to conduct clinical, imaging, laparoscopic and histological analyses of peritoneal endometriosis (PE) in adolescents in order to improve early diagnosis.

Methods: In total, 134 girls (from menarche to 17 years old) were included in a case-control study: 90 with laparoscopically (LS) confirmed PE, 44 healthy controls underwent full examination and LS was analyzed in the PE group.

Reconsidering evidence-based management of endometriosis.

Background: Without an adequate animal model permitting experiments the pathophysiology of endometriosis remains unclear and without a non-invasive diagnosis, information is limited to symptomatic women. Lesions are macroscopically and biochemically variable. Hormonal medical therapy cannot be blinded since recognised by the patient and the evidence of extensive surgery is limited because of the combination of low numbers of interventions of variable difficulty with variable surgical skills.

Laser vaporization compared with other surgical techniques in women with ovarian endometrioma: a systematic review and meta-analysis.

Objective: To compare outcomes after laparoscopic cystectomy versus laser vaporization in women of reproductive age with ovarian endometrioma.

Evidence Review: Our systematic review and meta-analysis was registered in PROSPERO (CRD42021281781) and was done according to the PRISMA 2020 checklist. Studies (published until October 2021) were identified by searching PubMed, Cochrane Library, Google Scholar, and ClinicalTrials.

Malignant Clinical Course of "Proliferative" Ovarian Struma: Diagnostic Challenges and Treatment Pitfalls.

Struma ovarii (SO) is a monodermal teratoma predominantly composed of thyroid tissue (TT) showing benign, “proliferative”, or malignant histology. By imaging, a 38-year-old patient with lower backache revealed a 6.2-cm vertebral lesion (L5).

[Clinical guidelines «Polycystic Ovary Syndrome»].

Polycystic ovary syndrome (PCOS) is a polygenic endocrine disorder caused by both genetic and epigenetic factors. Depending on the period of a woman's life, the clinical picture, diagnosis, and treatment tactics of the disease are different. PCOS has a complex of reproductive, metabolic and psychological characteristics.

A Review of Recent Studies on the Effects of SARS-CoV-2 Infection and SARS-CoV-2 Vaccines on Male Reproductive Health.

According to world statistics, men are more susceptible to the coronavirus disease 2019 (COVID-19) than are women. Considering the interconnection between infections and male infertility, investigation of the potential impact of COVID-19 on men's reproductive health is now a particularly relevant topic. Published data indicate decreased sperm quality and orchitis development in patients with COVID-19, including reduced sperm count, decreased sperm motility, and elevated DNA fragmentation index.

Familial Predisposition to Leiomyomata: Searching for Protective Genetic Factors.

In order to determine genetic loci associated with decreasing risk of uterine leiomyomata (UL), a genome-wide association study (GWAS) was performed. We analyzed a group of patients with a family history of UL and a control group consisting of patients without uterine fibroids and a family predisposition to this pathology. Six significant single nucleotide polymorphisms were selected for PCR-genotyping of a large data set of patients with UL.

Peritoneal fluid progesterone and progesterone resistance in superficial endometriosis lesions.

Peritoneal fluid in ovulatory women is an ovarian exudate with higher estrogen and progesterone concentrations than in plasma. In the follicular phase, progesterone concentrations are as high as plasma concentrations in the luteal phase. After ovulation, estrogen and progesterone concentrations in the peritoneal fluid are 5-10 times higher than in plasma, both in women with and without endometriosis.

Alterations in lipid profile upon uterine fibroids and its recurrence.

Uterine fibroids (UF) is the most common (about 70% cases) type of gynecological disease, with the recurrence rate varying from 11 to 40%. Because UF has no distinct symptomatology and is often asymptomatic, the specific and sensitive diagnosis of UF as well as the assessment for the probability of UF recurrence pose considerable challenge. The aim of this study was to characterize alterations in the lipid profile of tissues associated with the first-time diagnosed UF and recurrent uterine fibroids (RUF) and to explore the potential of mass spectrometry (MS) lipidomics analysis of blood plasma samples for the sensitive and specific determination of UF and RUF with low invasiveness of analysis.

Prevalence of Endometriosis and Peritoneal Pockets in Women with Infertility and/or Pelvic Pain.

Objective: To evaluate the prevalence of endometriosis and peritoneal pockets and to analyze whether these pockets are associated with pain.

Methods: Analysis of prospectively registered data of all women undergoing laparoscopy for infertility or pelvic pain between 1988 and 2011 at KU Leuven University Hospital.

Results: Of 4497 women, 191 had 238 pockets, with a prevalence of 4.

Surgical management of endometriosis-associated pain.

Endometriosis and pelvic pain are associated. However, only half of the subtle and typical, and not all cystic and deep lesions are painful. The mechanism of the pain is explained by cyclical trauma and repair, an inflammatory reaction, activation of nociceptors up to 2.

Gene Expression Signature of Endometrial Samples from Women with and without Endometriosis.

Study Objective: To develop a prototype of a complex gene expression biomarker for the diagnosis of endometriosis on the basis of differences between the molecular signatures of the endometrium from women with and without endometriosis.

Design: Prospective observational cohort study. Evidence obtained from a well-designed, controlled trial without randomization.

The epidemiology of endometriosis is poorly known as the pathophysiology and diagnosis are unclear.

As the diagnosis requires a laparoscopy, we only have data in women with pain and/or infertility. Endometriosis has been considered to be a single disease defined as 'endometrium like glands and stroma outside the uterus'. However, subtle, typical, cystic ovarian and deep endometriosis lesions should be considered to be different pathologies which occur in all combinations and with different severities.
