The Effect of Progesterone Elevation on the Day of Trigger Administration: A Review of the Literature.

Since the advent of assisted reproductive technology, different variables have been shown to affect pregnancy outcomes. One of the most prevalent studied events is the premature rise in serum progesterone concentrations on the day of trigger administration during cycles of ovarian stimulation. This phenomenon, classically known as premature luteinization, has been observed significantly for decades and has been linked to adverse pregnancy outcomes and lower live birth rates.

Management of Twin Pregnancy Complications Amid COVID-19: Posterior Colpotomy Approach for Abdominal Cerclage Removal at 18 Weeks Gestation - A Case Report.

BACKGROUND Cervical incompetence and deformities contribute significantly to mid-trimester pregnancy losses and preterm births. Abdominal cerclages prevent these complications, particularly in patients with a history of failed vaginal cerclage or severe cervical deformities. However, pregnancy complications such as chorioamnionitis and fetal demise may necessitate cerclage removal.

Idiopathic Osteosclerosis and Condensing Osteitis in a Sample of the Lebanese Population: A Digital Panoramic Based Study.

Background: Idiopathic osteosclerosis (IO) is an area of enlarged bone production in the jaw that usually appears radiopaque and round, elliptical, or irregular in shape. Condensing osteitis (CO) is a focalized osseous reaction leading to periapical sclerotic bone growth.

Objective: The aim of this study was to investigate the prevalence, localization, shape, and dental relationship of IO and CO in a group of Lebanese patients and to correlate these findings to age and gender.

Bone Apposition in the Mandibular Angle in Adult Patients Diagnosed with Bruxism: a Digital Panoramic Based Study.

Background: Bruxism is defined as a movement disorder of the masticatory system leading to serious problem in the integrity of the oral dentition; it is characterized by teeth grinding and clenching and has been typically classified into three types: a) bruxism occurring during sleep, b) awake-related bruxism, and c) mixed sleep/awake-related bruxism.

Objective: The aim of this study was to assess any bone apposition in the mandibular angle in a group of adult patients diagnosed with bruxism using digital panoramic radiographs.

Methods: In the sample of 150 digital panoramic radiographs of 66 women and 84 men with an age range of 24-78 years and diagnosed with bruxism were evaluated.

Mapping Maxillary Sinus Septa in a Lebanese Sample: a Radio-anatomical Study.

Introduction: Sinus septa are bony processes that develop in a variable fashion. Such structures present a challenge for surgical procedures of the maxillary sinuses.

Aim: This study aims to evaluate the prevalence and patterns of maxillary sinus septa in a sample from the Lebanese population.

Steroid hormone pretreatments in assisted reproductive technology.

Adequate availability and FSH sensitivity of ovarian antral follicles and coordination of their growth during controlled ovarian hyperstimulation (COH) rank among factors that may determine outcome, particularly in patients presenting ovarian function defects and so-called "poor responders." Growing evidence indicates that both factors are positively influenced by steroid hormone pretreatments. First, data from studies conducted in both animals and in women exposed to virilizing androgen doses indicate that androgen pretreatments may increase follicle responsiveness to FSH and/or the number of growing follicles in the ovary, thereby constituting an interesting perspective in the management of "poor responders.

New automated antimüllerian hormone assays are more reliable than the manual assay in patients with reduced antral follicle count.

Objective: To compare the strength of the relationship between antral follicle count (AFC) and serum antimüllerian hormone (AMH) concentrations obtained with two automated and one manual AMH assays in three different AFC populations.

Design: Prospective cohort study.

Setting: University-affiliated IVF-ET center.
