Tartrazine, an azo dye prevalent in pharmaceuticals and food items, was investigated for its impact on fetal development, specifically examining visceral and skeletal abnormalities in rat offspring exposed to daily oral doses throughout pregnancy. Fourteen pregnant rats were randomly assigned to control and tartrazine groups (seven animals each), with tartrazine administered via oral gavage at 7.5 mg/kg throughout gestation.

Background/aim: This study investigated the possible degeneration in cochlear morphology induced by preeclampsia (PE) and the therapeutic/preventive effect of vitamin D (Vit D) and magnesium sulfate (MgSO) used separately and together on feto-maternal outcomes.

Materials And Methods: We created PE in rats using a reduced uterine perfusion pressure (RUPP) animal model and recorded blood pressure (BP), embryonic survival (ES), and embryonic weight (EW) and evaluated cochlear morphology by electron microscopy.

Results: The PE group had elevated BP, a decreased number and weight of live pups, and significant degeneration in the cochlea compared to the sham group.

Objective: In this study, we created an animal model to demonstrate the effects of thiamine on the hearing pathways of new-borns during pregnancy and lactation by inducing a dietary thiamine deficiency in the mother.

Methods: The study included 16 female Wistar albino rats. The animals were separated into four groups and provided the appropriate amounts of dietary thiamine according to their groups during pre-pregnancy, pregnancy, and lactation periods.

Background: Recent studies reported the relationship between genetic variations and TAS2R38, which is a bitter taste receptor expressed in the cilia of human sinonasal epithelial cells, among the predisposing factors playing role in immune response to upper respiratory tract bacterial infection. The present study aims to examine the relationship of TAS2R38 genotype with the active microorganism and the effect of genotype on the surgical outcomes among chronic rhinosinusitis patients.

Methodology: 34 patients undergoing endoscopic sinus surgery (ESS) for chronic rhinosinusitis with or without polyps (23 CRSwNP, 11 CRSsNP) and 30 patients undergoing septoplasty surgery for isolated nasal septum deviation were included.

Background: Systemic immune-inflammatory index (SII), which is derived from neutrophil, platelet and lymphocyte counts, represents the homeostatic balance among inflammatory, immune and thrombotic status. The systemic immune-inflammatory index is superior to indices such as neutrophil-lymphocyte ratio in predicting prognosis in various malignancies, while it is shown to predict future cardiac events better than traditional risk factors after coronary intervention.

Objectives: Herein, we aimed to evaluate the relationship of the systemic immune-inflammatory index with atherosclerotic burden and in-hospital complications in acute coronary syndrome patients.

Article Synopsis
  • The study investigates the role of periostin as a potential biomarker for chronic rhinosinusitis with nasal polyps (CRSwNP) and its relationship with polyp burden and surgical outcomes.
  • In a sample of 26 CRSwNP patients undergoing endoscopic surgery and 30 patients undergoing septoplasty, they measured preoperative and postoperative scores along with tissue and serum periostin levels.
  • Findings showed that periostin levels were significantly higher in CRSwNP patients and correlated positively with tissue eosinophils and postoperative symptom scores, suggesting it could be useful for assessing disease severity and prognosis.

Background: Obesity is a common and growing health problem in vascular surgery patients, as it is in all patient groups. Evidence regarding body mass index (BMI) on endovascular aneurysm repair (EVAR) outcomes is not clear in the literature. We aimed to determine the impact of obesity on perioperative and midterm outcomes of elective EVAR between obese and non-obese patients.

Background/aim: Paget’s disease (PD) of the breast is a very rare presentation of breast malignancy, accounting for 1%–3% of all primary breast tumors. We aimed to evaluate and compare the clinicopathological features and clinical outcome of PD accompanied by in situ carcinoma and invasive cancer.

Materials And Methods: We used the archive of our pathology laboratory retrospectively for age, sex, history of surgery, histopathological findings, treatment modalities, and follow-up information.

Objectives: Vocal fold nodules (VFN) are a bilateral epithelial thickening of the membranous vocal folds. In this study, children with VFN and their mothers took part in voice therapy. We then compared acoustic analyzes and subjective evaluations to those in previous literature to determine whether voice therapy is more effective for children with VFN when their mothers also take part in therapy.

Calculation of effective orifice area (EOA) is crucial for the evaluation of prosthetic valve (PV) function and there is lack of data on the best method, particularly in obese patients, in whom two-dimensional (2D) transthoracic echocardiography (TTE) is cumbersome. We sought to compare two methods of calculating EOA through Continuity equation; one using standard 2D-TTE and other three-dimensional (3D) stoke volume (SV), in patients with bileaflet mechanical PV stratified by body mass index (BMI). On conventional TTE, SV mas measured using standard 2D derived data and 3D derived SV in 38 aortic and 62 mitral PV patients who were referred for further evaluation for mild/moderate symptoms of dyspnea.

Background: Iatrogenic biliary tract injury (BTI) is a rare complication but has high risks of morbidity and mortality when it is not early noticed. Although the treatment varies depending on the size of injury and the time until the injury is noticed, endoscopic and percutaneous interventions are usually sufficient. However, it should be remembered that these interventions may cause major complications in the following years, such as biliary stricture, recurrent episodes of cholangitis and even cirrhosis.

Background/aim: Esmolol and amiodarone are two most commonly used antiarrhythmic drugs in coronary artery bypass grafting (CABG) surgery. Nevertheless, blockade of beta-2 receptors by increasing doses raise concerns about possible vasospasms. We studied the vasoactive effects of amiodarone and esmolol on left internal mammary artery (LIMA), radial artery (RA), and saphenous vein (SV) grafts.

Aim: Peripheral artery disease (PAD) is a manifestation of atherosclerosis with poor prognosis. It is generally complicated by vascular calcification, which is located either in the intima as patchy infiltrates; or circumferentially in the media, also known as medial arterial calcification (MAC). Obstructive PAD is reflected by low anklebrachial index (ABI ≤ 0.

This study aimed to compare the real-life results of TECAM, a thiotepa-based conditioning regimen consisting of thiotepa (40 mg/m days -5 to -2), etoposide (200 mg/m days -6 to -3), cytarabine (200 mg/m days -4 to -1), cyclophosphamide (60 mg/kg day -3), and melphalan (60 mg/m days -2 to -1) with that of the conventional carmustine-based regimen BEAM. We reviewed 125 consecutive patients who underwent a first autologous transplantation (ASCT) for B-cell lymphomas at a large tertiary transplantation center between 1999 and 2014. TECAM (n=65) and BEAM (n=60) had comparable results (3yPFS 49 vs 62%, P=0.
