PD-L1 and PD-L2 Expression in Different Tumor Stages and Types of Malignant Salivary Gland Neoplasms: A Single-center Experience.

There is a limited amount of data on the role of programmed cell death ligand (PD-L) -1 and PD-L2 in salivary gland carcinomas. We aimed to evaluate the prognostic value of PD-L1 and PD-L2 expressions, which are closely related to immune mechanisms, with respect to salivary gland tumor types and stages. Data from patients with salivary gland masses surgically removed between 2006 and 2021, diagnosed with a malignant salivary gland neoplasm, were retrospectively analyzed.

Predictive Power of Self-Efficacy on the Fear of Childbirth in Pregnant Women: Underlying Mechanisms of Social Support as a Mediator and the COVID-19 Fear as a Moderator.

Background: Fear of childbirth (FOC) is a common problem associated with psycho-social factors in pregnant women.

Objectives: This study aimed to determine the mediator of social support and the moderator role of fear of coronavirus disease 2019 (COVID-19) in the relationship between self-efficacy and FOC in pregnant women.

Materials And Methods: This descriptive and cross-sectional study was conducted with 422 pregnant women registered in 18 family health centers.

Long term effects of cochlear implant surgery on vestibular system in pediatric population.

Objective: The aim was to evaluate the vestibular system of children who had undergone cochlear implant surgery and to compare them with the healthy population by vestibulo-ocular reflex (VOR) gains in unilateral and bilateral implant users, with the implants both on and off.

Methods: Patients older than 5 years who had undergone cochlear implant surgery between 2012 and 2020 and who were cochlear implant users for at least one year were included. After consent was obtained, a video head impulse test (VHIT) was performed to evaluate the three semicircular canals, with devices on and off, and VOR gains were evaluated.

Corrective Effect of Verbascoside on Histomorphological Differences and Oxidative Stress in Colon Mucosa of Rats in Which Colon Ischemia-Reperfusion Injury was Induced.

Background: This study aims to show the corrective effect of verbascoside on histomorphological and biochemical differences in the colon mucosa of rats in which colon ischemia-reperfusion (I/R) injury was induced.

Methods: Fifty Sprague Dawley male rats were divided into 5 groups, of control, sham, ischemia (I), I/R, and I/R+verbascoside. Ischemia and reperfusion were applied to the suitable groups for 30 minutes and 120 minutes respectively, and 10 mg/kg verbascoside was administered intraperitoneally.

Clinical experience and treatment approaches in sinonasal osteomas from a Tertiary Care Hospital in Turkey.

Objective: Osteomas are slow-growing benign osseous tumors that particularly located in the paranasal sinuses (PS). Here, we aimed to define the clinical symptoms and features, diagnostic conditions caused by osteomas located in four different PSs, to evaluate the surgical indications and methods, to compare the factors that can affect the surgical decision, radiological findings, and prognosis.

Methods: The data of patients with paranasal sinus lesions and diagnosed as osteoma according to the radiological imaging, who applied to our clinic between 2010 and 2020, were retrospectively collected and re-evaluated in the light of clinical, radiological, and pathological data.
