Comparison of the diagnostic value of histopathological examinations of miscarriage products after pharmacological induction of miscarriage and curettage

Objectives: For early miscarriage (pregnancy loss ≤ 12 weeks of gestation), two types of therapeutic treatment are offered (pharmacotherapy and curettage of the uterine cavity) depending on the presence and severity of clinical symptoms as well as patient choice. Our study aimed to assess the diagnostic value of the results of histopathological examinations of miscarriage products in relation to the administered treatments.  Material and methods: 850 medical records from patients diagnosed with missed miscarriage or empty gestational sac were analyzed retrospectively. Patients underwent surgical treatment or pharmacotherapy. Inefficacy of pharmacotherapy resulted in subsequent curettage. The results of histopathology were evaluated for their diagnostic value and classified: subgroup 1 — high value specimen (the studied specimen included fetal tissues, and villi), and subgroup 2 — no-diagnosis (the studied specimen included maternal tissues, autolyzed tissues, blood clots). Data were compared with chi-squared test. Differences was considered significant at p < 0.05.  Results: 1128 histopathological test results were analyzed; 569 (50.4%) were obtained during pharmacotherapy and 559 (49.6%) after curettage; out of the latter 497 after the initial pharmacotherapy and 62 after surgery. In the pharmacotherapy group, high value specimens comprised 231 cases (40.59%) while no diagnosis was obtained in 338 cases (59.4%). Considering specimens obtained in the course curettage, high value specimens were found in 364 cases (65.1%) while results that did not allow a diagnosis to be made were found in 195 cases (34.9%).  Conclusions: Tissue specimens of high diagnostic value are obtained significantly more often during surgical treatment of miscarriage than during pharmacotherapy

Anterior abdominal fixation — a new option in the surgical treatment of pelvic organ prolapse

Objectives: To present anterior abdominal fixation — a new surgical technique for the treatment of pelvic organ prolaps (POP) and to evaluate the results of the treatment of patients with stage III and IV POP operated using this technique.Material and methods: Anterior abdominal fixation for treating stage III and IV POP was carried out in 42 women, who were qualified according to the Pelvic Organ Prolapse Quantification System (POP-Q) scale at baseline and after 12 months. The Pelvic Floor Disability Index-20 (PFDI-20), along with its symptom scales, were evaluated.Results: The mean age 42 operated women was 64.5 years, and the average BMI was 27.3 (83% women were overweight). At baseline, 29 (69%) women had POP stage IV, and 13 (31%) women had POP stage III. Overall, 14 (33%) underwent laparoscopy, 28 (67%) underwent laparotomy. At 12 months, 14 (33.3%) women had POP stage I; 21 (50%) women had POP stage II. Seven patients (16.6%) experienced a recurrence of disease with advancement at the degree of III/IV; 4 (9.5%) women required adjuvant surgery in the form of anterior and posterior vaginal wall surgery. No early complications after surgery were observed. The comparison of the results before and after surgery showed statistically significant improvement in terms of the P-QoL score as well as PFDI-20 along with its 3 symptom scales.Conclusions: Anterior abdominal fixation of the uterus to the anterior abdominal wall is effective, safe, and technically easy to perform in the treatment of POP of advanced stage

Placental mesenchymal dysplasia and hepatic cyst

Placental mesenchymal dysplasia (PMD) is a rare benign vascular anomaly of the placenta. It can be misdiagnosed asa molar pregnancy resulting in unnecessary termination of pregnancy.A 30-year-old woman was referred to our hospital at 18 gestational weeks due to suspicion of molar pregnancy. The ultrasoundshowed a bulky placenta with multiple cysts. Oligohydramnion and fetal hypoechogenic cystic area without doppler flowwere diagnosed at 23 weeks. The baby was operated on after delivery, and an 80 mm multifocal cyst originating from the rightlobe of the liver was removed. The placenta demonstrated swelling stem villi with enlarged vessels and increased interstitialcells without trophoblast proliferation. PMD and fetal hepatic cyst can coexist; however, the relationship between thoseconditions remains to be elucidated. PMD is associated with adverse pregnancy outcomes but also with a good prognosis

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements
