Prognostic value of neutrophile-to-lymphocyte ratio (NLR) and lactate dehydrogenase (LDH) levels for geriatric patients with COVID-19.

Aim: In this study it was aimed to evaluate the prognostic factors for the geriatric patients with confirmed COVID-19 in a tertiary-care hospital at Kastamonu region of Turkey.

Method: Patients (≥65-year-old) who had PCR positivity for COVID-19 between March 2020 and April 2020 in our center were recorded retrospectively. A p value less than 0.

Determination of the ideal sampling technique to reduce repeated procedures:a comparative study including 393 fine-needle aspirations for thyroid nodules.

Background/aim: Fine-needle aspiration biopsy is an established method for the evaluation of thyroid nodules, but it has not been standardized worldwide yet. Adequacy of the aspirations is affected by several factors. The aim of this study is to determine the main factors affecting the adequacy and to suggest a procedural technique expected to reduce repeated procedures.

Effect of 900MHz electromagnetic fields emitted from cellular phones on fracture healing: an experimental study on rats.

Objective: The aim of this study was to investigate the effect of electromagnetic fields (EMFs) at 900 MHz frequencies on bone fracture healing.

Methods: The study included 30 adult male Wistar albino rats (average weight: 256 g) divided into two equal groups. Transverse fracture was created manually by pressing a finger on the right tibias of all rats and fractures were fixed intramedullary using a K-wire.

[Effect of bone cement application on the incidence of deep vein thrombosis in major joint arthroplasties].

Objectives: In this study, we have investigated whether the application of bone cement has an effect on the frequency of deep vein thrombosis (DVT) in major joint arthroplasties (MJA).

Patients And Methods: A total of 95 MJA cases meeting the inclusion criteria of this study between January 2004 and January 2005 were divided into cemented and cementless groups. For prophylaxis, all patients were given low molecular weight heparin (LMWH).

Determining the effectiveness of various treatment modalities in carpal tunnel syndrome by ultrasonography and comparing ultrasonographic findings with other outcomes.

Unlabelled: Firstly, we aimed to determine the effectiveness of various treatment modalities using ultrasonography (US), and secondly, we aimed to assess the correlations between the ultrasonographic findings and electrophysiological tests, symptom severity, functional status and physical findings. 74 hands of 47 patients with carpal tunnel syndrome (CTS) were randomly treated by applying wrist splinting alone in the neutral position (23 hands), phonophoresis with corticosteroid (PCS) (28 hands) and phonophoresis with non-steroid anti-inflamatory drug (PNSAI) (23 hands). The cross-sectional area (CSA) of the median nerve (MN) was determined by ultrasound on the initial and at the 3 months after treatment.

Biomechanical comparison of two different collar structured implants supporting 3-unit fixed partial denture: a 3-D FEM study.

Objective: The purpose of the study was to compare the effects of two distinct collar geometries of implants on stress distribution in the bone as well as in the fixture-abutment complex, in the framework and in the veneering material of 3-unit fixed partial denture (FPD).

Material And Methods: The 3-dimensional finite element analysis method was selected to evaluate the stress distribution in the system composed of 3-unit FPD supported by two different dental implant systems with two distinct collar geometries; microthread collar structure (MCS) and non-microthread collar structure (NMCS). In separate load cases, 300 N vertical, 150 N oblique and 60 N horizontal, forces were utilized to simulate the multidirectional chewing forces.

Biomechanical effects of two different collar implant structures on stress distribution under cantilever fixed partial dentures.

Objective: The purpose of the study was to compare the effects of two distinct collar geometries of implants on stress distribution in the bone around the implants supporting cantilever fixed partial dentures (CFPDs) as well as in the implant-abutment complex and superstructures.

Materials And Methods: The three-dimensional finite element method was selected to evaluate the stress distribution. CFPDs which was supported by microthread collar structured (MCS) and non-microthread collar structured (NMCS) implants was modeled; 300 N vertical, 150 N oblique and 60 N horizontal forces were applied to the models separately.

A simple clinical model composed of ECG, shock index, and arterial blood gas analysis for predicting severe pulmonary embolism.

Background: Objective diagnosis of severe pulmonary embolism (PE) is obligatory because of its considerable mortality.

Aim: To assess the abilities of electrocardiography (ECG) score (sECG) and the newly generated scoring system composed of the scores obtained from arterial blood gas (ABG) analysis and shock index (SI) in addition to sECG in predicting severe PE.

Material And Methods: The degree of pulmonary vascular obstruction (sPVO) and the right ventricular dysfunction (RVD) were determined with spiral computed tomography (CT) in 53 consequent patients with PE.

Stability of locking and conventional 2.0-mm miniplate/screw systems after sagittal split ramus osteotomy: finite element analysis.

Objective: The aim of this study was to evaluate the mechanical stresses over the bone and hardware after sagittal split ramus osteotomy (SSRO) fixed with standard titanium or locking plate/screws using finite element analysis.

Study Design: A 3-dimensional finite element model of the mandible was created, and SSRO and 5 mm advancement was simulated on a computer model. The model was fixed with either 2.

Erdosteine modulates radiocontrast-induced hepatotoxicity in rat.

It has been suggested that reactive oxygen species (ROS) plays an important role in radio contrast media (RCM)-induced ischemia reperfusion tissue injury although antioxidants may have protective effects on the injury. We investigated the effects of erdosteine as an antioxidant agent on RCM-induced liver toxicity in rats by evaluation of lipid peroxidation (as TBARS), catalase (CAT), superoxide dismutase (SOD), reduced glutathione (GSH) and glutathione peroxidase (GSH-Px) values and histological evaluation. Twenty-one rats were equally divided into three groups as follows: control, RCM, and RCM plus erdosteine.

The value of ultrasonographic measurement in carpal tunnel syndrome in patients with negative electrodiagnostic tests.

The diagnosis of carpal tunnel syndrome (CTS) is mainly based on clinical findings and electrodiagnostic tests (EDT). However, EDT results do not support clinical findings in some cases. It has been recently suggested that ultrasonography (US) can be used to diagnose CTS.
