Background: Benign prostatic hyperplasia unresponsive to medical treatment is an important problem for elderly patients. Although the gold standard surgical treatment is monopolar transurethral resection of the prostate (MTURP), postoperative complications are still a concern.

Aim: The aim of this study was to determine which transurethral prostate resection (TURP) methods are more effective and safer in elderly patients.

Objectives: Due to cross-clamping of the aorta during aortic aneurysm surgeries, ischemia-reperfusion (IR) develops, and it may cause damage to the aorta itself or even to remote organs by oxidative stress or inflammation. Fluoxetine (FLX) which might be used in the preoperative period for its tranquilizing effect also has antioxidant effects in short-term use. The purpose of our study is to examine whether FLX protects aorta tissue, against the damage caused by IR.

Introduction: This study aimed to compare the bond strength of teeth treated with radiotherapy with two cavity disinfectants (Chlorhexidine gluconate, a chitosan-containing agent).

Methodology: Eighteen newly extracted, non-carious human third molar teeth were used. The teeth were randomly divided into two main groups, treated and/or non-treated with radiotherapy, then separated into three subgroups for disinfectant agent application (CHX, chitosan, control).

Fossa navicularis (FN) is defined as bony depression that is not always present and is located anterior to the foramen magnum and pharyngeal tubercle on the inferior aspect of the basilar part of the occipital bone. It has been reported that FN can create an infection spread path from the pharynx to the intracranial structures. Therefore, the diagnosis of this variation is important.

Objective: To determine the clinical outcomes of prostatic artery embolization applied to patients with Material and methods: The study includes 30 patients diagnosed with benign prostatic hyperplasia in the urology clinic between 2012 and 2016, for whom anesthesia was contraindicated due to advanced age and comorbidities and who underwent prostatic artery embolization. These patients were evaluated before the procedure and in the 1st, 3rd, 6th, and 12th months after the procedure.

Results: The mean prostate volume of the patients was 68 cm3 before the procedure and 45 cm3 12 monthsafter the procedure.

Background: Malnutrition is associated with cardiovascular disease morbidity and mortality. Arrhythmias may be the cardiac consequences of malnutrition.

Objectives: The objective of the study was to evaluate the association between prognostic nutritional index (PNI), Controlling Nutritional Status (CONUT) score, and arrhythmic events on 24-h electrocardiography (ECG) Holter recording in patients without manifested arrhythmia.

Article Synopsis
  • The study explored the effectiveness of a novel sterilizable metal brush compared to other carriers for cryopreserving prepubertal testicular tissue.
  • The results indicated that the metal brush showed minimal cell damage and the highest viability rate of 91.6%, outperforming aluminum foil, metal wire, and high-security straw.
  • Findings suggest the metal brush is a promising option for improving the vitrification process in preserving testicular tissue for children undergoing gonadotoxic treatments.

Background and objective The morphology and morphometry of the foramen magnum (FM), which provides a passageway to vital neurological structures that relay information to and from the brain and spinal cord, are significant for many surgical approaches and applications. It was aimed to investigate the morphometric and morphological features of the FM on the cone-beam computed tomography (CBCT) images and to review the literature in detail. Methods CBCT images of 400 individuals (200 males, 200 females, aged between 18 and 65) were evaluated by Planmeca Romexis Viewer.

Background and objective The aim of this study was the examination of morphometry of the spinous process (SP) and interspinous space (ISS) of the lumbar region to help provide a basis for the design and implantation of interspinous devices. Methods Between 2017 and 2019, 215 individuals underwent magnetic resonance imaging of the lumbar region for various reasons. No pathology was detected in these images, and the participants' age, height, and weight information when available were included in the study.

In the literature, most of the craniofacial anthropometric landmarks found on both bones and soft tissue have been clearly defined and widely used. However, it seems that few landmarks such as nasion are generally often set incorrectly. Therefore, in this study, it was aimed to examine the nasion and sellion in the dry bones and to review the definitions of each landmarks.

Introduction: The aim of this study was to determine the incidence and morphometric and morphological characteristics of fossa navicularis (FN) on cone beam computed tomography (CBCT) images of healthy adults MATERIALS AND METHODS: CBCT images of 900 individuals (450 males, 450 females, over the age of 18) admitted to Gaziantep University, Dentistry Faculty were retrospectively examined. The incidence and shape of FN were determined. Transverse diameter (TDFN), sagittal diameter (SDFN), depth in transverse section (DFNT), depth in sagittal section (DFNS), and the shortest distance between the deepest point of FN and intracranial cavity (FNI) were measured.
