Prevention of secondary caries using fluoride-loaded chitosan nanoparticle-modified glass-ionomer cement.

Objective: To study the effect of incorporating chitosan and fluoride-loaded chitosan nanoparticles into a glass-ionomer cement (GIC) to prevent secondary caries.

Materials And Methods: A standard cervical cavity (mesio-distal width 6 mm, cervico-occlusal width 2 mm, and depth 2 mm) was prepared on 30 molars for the following restoration groups: group 1, conventional GIC restoration; group 2, chitosan (10%) modified GIC restoration; group 3, fluoride loaded chitosan nanoparticles (10%) modified GIC restoration. The restored teeth were subjected to 1,500 thermal cycles before undergoing a multi-species cariogenic biofilm challenge.

Determination of Low IgG Class Antibody Avidity Percentage by IgM Levels Specific to Toxoplasma Gondii.

Background: Ig (Immunglobulin) M detection and low avidity index are markers of recent infection in differentiating acute and chronic stages of Toxoplasma gondii (T. gondii) infections. In this study, we aimed to evaluate whether the anti-T.

A rare cause of acute abdominal pain: Actinomyces infection of colon mimicking a malignant neoplasm due to intrauterine device.

Actinomycosis is a rare, chronic granulomatous disease that is challenging to diagnose because the clinical symptoms and signs are nonspecific. Usage of intrauterine device (IUD) or being immunocompromised is facilitating factors. Clinical and radiological findings can mimic malignant neoplasm, inflammatory bowel disorder, or acute diverticulitis.

Evaluation of the relationship between progression and SARS-CoV-2 viral load in COVID-19 cases in Ankara, Turkey.

Introduction: Patients infected with SARS-CoV-2 may present with varying clinical pictures. This study aimed to examine the relationship between viral load cycle threshold value, clinical prognosis and other laboratory parameters in initial swab samples on the day of hospitalization.

Methodology: This retrospective and cross-sectional study included 112 patients, who were diagnosed with SARS-CoV-2 via the Bio-Rad CFX96 TouchTM system.

Investigation of Viral Load Cycle Threshold Values in Patients with SARS-CoV-2 Associated Pneumonia with Real-Time PCR Method.

Introduction: In this study, we aimed investigate the relationship of SARS-CoV-2 viral load cycle threshold (Ct) values with pneumonia.

Methodology: A total of 158 patients in whom SARS-CoV-2 was confirmed in upper respiratory tract (URT) samples with molecular method and who had computed tomography (CT) of the chest, between April 2020 and June 2020 were included in this retrospective cross-sectional study.

Results: Mean age of 158 PCR positive patients was 45.

Carbapenem and Colistin Resistant Klebsiella Pneumoniae ST14 and ST2096 Dominated in Two Hospitals in Turkey.

Background: The determination of clonal interactions between microorganisms is very important in epidemiological studies. In the present study, we aimed to evaluate the resistance mechanisms and genetic relationships of carbapenem and colistin resistant Klebsiella pneumoniae (K. pneumoniae) strains isolated from inpatients at two university hospitals in Turkey.

An Investigation into Bacterial Bloodstream Infections and Antibiotic Resistance Profiles in a Tertiary Hospital for a Ten-Year Period.

Background: Bloodstream infections are one of the major causes of healthcare-associated morbidity and mortality. The present study aims to investigate the prevalence of the microorganisms isolated from blood cultures and to evaluate susceptibilities to antimicrobial agents in a tertiary center, Gulhane Training and Research Hospital, Ankara, Turkey.

Methods: Blood cultures (BCs) were incubated in BACTEC/9050 (Becton Dickinson, USA) (2007 - 2015) and BacT/ALERT (bio-Merieux, France) (2014 - 2016) automated systems.

Medicinal leech therapy-an overall perspective.

Complementary medicine methods have a long history, but modern medicine has just recently focused on their possible modes of action. Medicinal leech therapy (MLT) or hirudotherapy, an old technique, has been studied by many researchers for possible effects on various diseases such as inflammatory diseases, osteoarthritis, and after different surgeries. has widest therapeutic usage among the leeches, but worldwide, many different species were tested and studied.

Evaluation of the BACTEC MGIT 960 SL DST Kit and the GenoType MTBDRsl Test for Detecting Extensively Drug-resistant Tuberculosis Cases.

Objective: The present study aimed to evaluate the performances of the BACTEC MGIT 960 SL DST kit and the GenoType MTBDRsl test for detecting second-line antituberculosis drug resistance in Multidrug-resistant TB (MDR-TB) cases.

Materials And Methods: Forty-six MDR-TB strains were studied. Second-line antituberculosis drug resistances were detected using the BACTEC MGIT 960 SL DST kit and the GenoType MTBDRsl test.

Comparison of probe disinfection procedures in routine ultrasonography: hot water versus antiseptic wiping.

Objective: It is commonly known that ultrasonography (US) transducers function as both a reservoir and means of transfer for hospital infections. The current study aimed to compare the antimicrobial effectiveness of using >80 °C water versus antiseptic wipes to disinfect US transducers.

Methods: Subsequent to abdominal inspections in three groups of 20 patients, a swab culture was taken from the transducer in each case.
