Periodontal changes induced by fixed orthodontic therapy.

Background: Orthodontic therapy is a complex process involving a series of specialists in the dental field: the oral-maxillo-facial surgeon, the periodontologist, sometimes even the prosthetist, implantologist, or general practitioners. The injuries of the oral mucosa induced by orthodontic therapy include gingival overgrowths, traumatic lesions of the oral mucosa, different degrees of periodontal damage manifested by gingival retraction, alveolar bone resorption.

Methods: From a total of 327 subjects who came to the Dental Clinic in Craiova 74 subjects were selected, who presented with gingival overgrowth associated with fixed orthodontic therapy.

Progress Toward Reversed Uterine Diastolic Flow in the Third Trimester - An Inauspicious Sign.

Background: Increased uteroplacental resistance is associated with high uterine artery pulsatility and resistance indices and early diastolic notching. Evolution toward reversed diastolic uterine flow in the third trimester was scarcely reported previously. The feature was related to severe complications for both mother and fetus.

Mental Well-Being of Nursing Staff and Destructive Role of COVID-19 Fear and Perceived Stress.

Health crises across the globe bring dramatic changes to the lives of individuals and organizations. These crises have some psychological effects on society. The COVID-19 pandemic also caused some serious problems for individual and organizational life.

Learning deep architectures for the interpretation of first-trimester fetal echocardiography (LIFE) - a study protocol for developing an automated intelligent decision support system for early fetal echocardiography.

Background: Congenital Heart Disease represents the most frequent fetal malformation. The lack of prenatal identification of congenital heart defects can have adverse consequences for the neonate, while a correct prenatal diagnosis of specific cardiac anomalies improves neonatal care neurologic and surgery outcomes. Sonographers perform prenatal diagnosis manually during the first or second-trimester scan, but the reported detection rates are low.

Can Ultrasound Analysis of the Yolk Sac be a Predictor of Pregnancy Outcome?

The Yolk sac is the first source of transfer between the mother and the embryo, with a nutritional and gas exchange function, vital for the development of the embryo, to which we can add primitive hematopoiesis, the production of stem cells and germ cells. Although normal-term pregnancies with abnormal aspects of the yolk sac have been described, the smaller or larger size of the yolk sac is associated with pregnancy loss. Our study aimed to determine whether the yolk sac size change, determined by measuring diameter (2D ultrasonography) or volume (3D ultrasonography), is independently associated with adverse pregnancy outcomes.

Prenatal findings and pregnancy outcome in fetuses with right and double aortic arch. A 10-year experience at a tertiary center.

Objective: Our objective was to evaluate the accuracy of the prenatal diagnosis and the relation between the type of right aortic arch (RAA) with other intra- or extracardiac (EC) and chromosomal anomalies.

Methods: A retrospective, observational study was conducted between 2011-2020 in a Romanian tertiary center. All RAA cases, including double aortic arch (DAA), were extracted from the databases and studied thoroughly.

The Implications of the First Trimester 2d and Volumetric Ultrasound in Pregnancy Outcome.

Background: The purpose is to investigate the role of the first trimester ultrasound markers: cown rump lengh (CRL), gestational sac volume (GSV), embryonic volume (EV) and yolk sac volume (YSV) as parameters for outcome.

Methods: Observational clinical study that was carried out in the Obstetrics and Gynecology Clinic. The study included a number of 81 unselected patients evaluated from the first trimester.

The performance of hyperadherence markers in anterior placenta praevia overlying the Caesarean scar.

Objectives: To assess the ultrasound (US) impact in diagnosing placenta accreta (PA) in patients with anterior placenta praevia localization, overlying a Caesarean scar.

Patients, Materials And Methods: This is a prospective study between January 2016 and December 2017 that included patients with Caesarean scar and placenta praevia in the third trimester of pregnancy. By means of two-dimensional (2D) grayscale and color Doppler, we investigated the presence of the following US markers for placental invasion: intraplacental lacunae, abnormal blood vessels at the myometrium-bladder interface, thinning of the hyperechogenic uterine serosa-bladder wall interface, loss of normal hypoechoic retroplacental myometrial space.

The importance of perinatal autopsy. Review of the literature and series of cases.

Perinatal autopsy remains the gold-standard procedure used to establish the fetal, neonatal or infant abnormalities. Progressively, perinatal pathology has become a specialized field with important roles of audit for fetal prenatal diagnostic tools, in parents counseling regarding future pregnancies, in scientific research, for epidemiology of congenital abnormalities and teaching. The differences between prenatal ultrasound and autopsy reports represent a strong argument for the autopsy examination following termination of pregnancy.

Stillbirth in dichorionic twins discordant for major and minor anomaly, followed by asynchronous delivery - a rare occurrence. Case presentation.

The single stillbirth long-term intrauterine retention in dichorionic twin pregnancy is rarely reported. Also, the birth of a fetus is followed in most cases by immediate expulsion of the second twin. We hereby present an unusual case of asynchronous delivery of dichorionic twins, associating discordance for major and minor anomaly.

Study of some invasiveness markers as pathogenic factors in oral pseudoepitheliomatous hyperplasia.

Pseudoepitheliomatous hyperplasia is a benign reactivated epithelial lesion secondary to another pathology, whose incidence is difficult to establish. There still exist controversies regarding the origin and pathogenesis of these lesions. For this purpose, we performed an immuno-histochemical study upon 20 cases of oral pseudoepitheliomatous hyperplasia associated with inflammatory and neoplastic conditions, investigating a series of markers with a possible pathogenic potential in developing this type of lesions.
