Determining the COVID-19 Knowledge, Awareness and Anxiety Levels of Intern Dentists

Introduction: COVID-19 is a contagious disease caused by Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2). The nature of dentistry leads to close contact with patients and exposure to saliva, blood, and other bodily fluids during treatment processes and it is a field where high-frequency devices that can make it easier for virus contamination are used. This study aims to determine the knowledge and approaches of COVID-19 infection control of intern dentists who have begun face-to-face education and their COVID-19-related fear and anxiety levels. Methods: The study comprised 4th and 5th-year students who began face-to-face education at the Ankara University Faculty of Dentistry 2020/2021 spring semester. A questionnaire was used as the data collection tool for this study. The data were collected using a knowledge questionnaire and a COVID-19 fear and anxiety scale. Results: The average COVID-19 knowledge score of the students was 63.65±9.64, their coronavirus fear average score was 17.63±5.57, and their anxiety average score was found to be 2.37±3.32. A positive relationship was found between the anxiety scores and the COVID-19 fear scores. The results of this study show that the COVID-19 knowledge level and fear of dentistry students are moderate and that their COVID-19 anxiety level is low. Conclusion: It was found that the knowledge and fear of coronavirus levels of intern dentistry students were moderate and that their coronavirus anxiety level was low

Influence of colonic mesenteric area on the number of lymph node retrieval for colon cancer: a prospective cohort study

Purpose The minimum harvested 12 lymph nodes (LNs) is regarded as the limit for accurate staging of nodal status in colorectal cancer patients. Besides the association of the lengths of resected intestinal segments and vascular pedicles, the mesocolic mesenteric area’s impact on LN count has not been studied. We aimed to evaluate the associations between metric variables, including the mesocolic mesentery area on the nodal harvest. Methods All consecutive patients who underwent elective colectomy with a curative intention for colon adenocarcinoma were prospectively included. The metric variables included the lengths of resected intestinal segments, vascular pedicle, and colonic mesenteric area. The variables influencing the LN count and the correlation between the total LN count and the specimens’ relevant metric measurements were analyzed. Results There were 46 patients with a median age of 64 years. The median count for total LNs was 22, and the LN positivity was 59.2%. There was an inadequate LN yield (0.05). There were significant positive correlations between total LN number and length of vascular pedicle and mesenteric area (r=0.576, P<0.001 and r=0.566, P<0.001). Conclusion The length of the vascular pedicle and mesenteric area were significantly correlated with total LN counts. Although there was no significant impact on the length of resected segments, the colonic mesenteric area can be used alone as a measure for the assessment of the nodal yield in colon cancer

Morphometric anatomic study and clinical significance of the collateral ligaments of the thumb interphalangeal joint

We aimed to emphasize the clinical significance of the collateral ligaments of the thumb interphalangeal joint through a morphometric anatomical study. Our study was performed on the thumbs obtained from 10 fresh cadavers in Akdeniz University Faculty of Medicine Anatomy Department Laboratory. The collateral ligaments in the thumb interphalangeal joint were examined and morphometric analysis was carried out using MicroScribe G2X. It was observed that the collateral ligaments are made up of proper (pCL) and accessory (aCL) components. pCL extends from the dorsal surface of the proximal phalanx head to the palmar surface of the proximal end of the distal phalanx, while aCL extends obliquely from dorsal to palmar and from proximal to distal and attaches to the palmar plate. The mean vertical and transverse diameters of the collateral ligament in the proximal interphalangeal joint were 12±2 mm (10 mm min 14 mm max) and 3±1 mm (2 mm min 4 mm max), respectively. Knowing the anatomy and morphometry of the collateral ligaments of the thumb interphalangeal joint will shed light on the surgical techniques that are to be applied in the reconstructions of injured ligaments.

Morphometric and Morphologic anatomic study and clinical significance of Greater tubercle

In this study, in tuberculum majus fractures, which are proximal humerus fractures; Morphometric measurements were made to guide surgeons and future implants. With the morphometric measurement of the greater tubercle, the length of the base, the length of the height, the length at its widest part, and its circumference were calculated. A 3D scanning device (Faro Focus 3D S120 Scanner Rental) was used to scan the proximal part of the humerus, and the proximal ends of the scanned humerus were transferred to the computer and morphometric measurements were made with the software program. As a result of the measurements made: Average base length of the large tubercle 26±2.34 mm, average anterior height of the greater tubercle 30±2.50 mm, average posterior height of the greater tubercle 9.5±0.4 mm and average Widest sagittal length of the greater tubercle 28.75±2.02 mm. We think that the morphological and morphometry of the tuberculum majus, which is one of the formations at the proximal end of the humerus, will guide surgeons with anatomically designed implants in surgical applications.

Association among Orthodontic Malocclusions, Paranasal Sinuses Anatomic Variations and Adenoid Vegetation in Children Using CBCT

The aim of this study is to evaluate the relationship between orthodontic malocclusion, paranasal sinus (PS) variations, and adenoid vegetation in a group of pediatric patients with chronic rhinosinusitis. Clinical and radiographical data were retrospectively evaluated and 58 patients were diagnosed as having chronic sinus disease. Cone-beam computed tomography (CBCT) images were acquired with Newtom-3G. Anatomical variations of the PS were assessed on every section. Additionally, for cephalometric analysis, the images were imported into the InVivoDental software program. A total of 252 anatomical variations, which encompassed 19 different types, were detected in the current study. Concha bullosa was the most common anatomical variation, at 72.4%. Septum deviation was the second most common one, at 67.2%. The Class III group exhibited a significantly higher prevalence of concha bullosa and secondary middle turbinate than the other groups. While adenoid vegetation was most common in the Class III group, sinusitis and antral disease were most common in the Class II group. Overall, Class III subjects exhibited fewer PS variations. In conclusion, concha bullosa emerged as the most prevalent anatomical variation, with distinctive patterns observed across different malocclusion groups. Therefore, CBCT is useful, especially in pediatric patients, due to its low dose advantage

Tracheal Rupture: A Rare Complication of Endotracheal Intubation

WOS: 000489006800009PubMed ID: 31620698Clinicians can encounter various complications after endotracheal intubation as a result of patient anatomy, difficult intubation, and time and number of interventions performed. A life-threatening complication of intubation is iatrogenic tracheal rupture that leads to pulmonary air leak syndromes. In this case report, we present a 10-month-old patient who presented to the healthcare center with cyanosis and cough after foreign body aspiration and underwent endotracheal intubation for hypoxia. In our report, we aim to draw attention to tracheal rupture, a complication that was identified in bronchoscopy and found to be associated with repeated interventions and stylet use

Glioma-on-a-Chip Models

Glioma, as an aggressive type of cancer, accounts for virtually 80% of malignant brain tumors. Despite advances in therapeutic approaches, the long-term survival of glioma patients is poor (it is usually fatal within 12–14 months). Glioma-on-chip platforms, with continuous perfusion, mimic in vivo metabolic functions of cancer cells for analytical purposes. This offers an unprecedented opportunity for understanding the underlying reasons that arise glioma, determining the most effective radiotherapy approach, testing different drug combinations, and screening conceivable side effects of drugs on other organs. Glioma-on-chip technologies can ultimately enhance the efficacy of treatments, promote the survival rate of patients, and pave a path for personalized medicine. In this perspective paper, we briefly review the latest developments of glioma-on-chip technologies, such as therapy applications, drug screening, and cell behavior studies, and discuss the current challenges as well as future research directions in this field

Could Platelet Indices and Neutrophil to Lymphocyte Ratio Be New Biomarkers for Differentiation of Arteritic Anterior Ischemic Neuropathy from Non-Arteritic Type?

The aim of this study was to assess the possible relationship between AAION (arteritic anterior ischemic optic neuropathy) and NAION (non-arteritic anterior ischemic optic neuropathy) with blood platelet parameters and NLR (neutrophil-to-lymphocyte ratio). The medical records of 12 patients with AAION, 33 patients with NAION, and 35 healthy subjects were examined. MPV, PDW, and PCT values showed marked elevation in AAION and NAION groups compared with control group. The mean NLR was statistically significantly higher only in AAION group compared to the NAION and control groups, suggesting that platelet function plays an important role in AIONs and NLR might be used to differentiate AAION from NAION

Determination of antioxidant activity and phenolic compounds for basic standardization of Turkish propolis

This study aimed to determine the standard amount of antioxidant content and compounds of the propolis for the standardization of propolis. For this purpose, the total flavonoids, total phenolic, CUPRAC antioxidant capacity content and the diversity of phenolic and flavonoid components of these propolis samples were found by HPLC determined at the 23 propolis samples which were collected different regions of Turkey. Beside that, the similarities and differences of these 23 provinces to each other according to their antioxidant capacities were investigated by multidimensional scaling analysis. The total flavonoid content in the propolis samples were determined between 21.28 and 152.56 mg CE/g. The total phenolic content in the propolis samples was found between 34.53 mg and 259.4 mg GAE/g. CUPRAC antioxidant capacity of the propolis samples and antioxidant range was found from 95.35 to 710.43 mg TE/g. Also, 4 flavonoid [Quercetin (min.1.12-max.4.14 mg/g), Galangin (min.0.72-max.40.79 mg/g), Apigenin (min.1.07-max.17.35 mg/g), Pinocembrin (min.1.32-max.39.92 mg/g] and 6 phenolic acid [Caffeic acid (min.1.20-max.7.6 mg/g), p-Coumaric acid (min.1.26-max.4.47 mg/g), trans-Ferulic acid (min.1.28-max.4.92 mg/g), Protocatechuic acid (1.78 mg/g), trans-Cinnamic acid (min.1.05-max.3.83 mg/g), Caffeic Acid Phenethyl Ester (CAPE) (min.1.41-max.30.15 mg/g)] components were detected as mg/g, in different ratios in propolis samples collected from different regions. The feature of this study, so far, is to have the maximum number of samples representing the Turkish propolis, and so is thought to help to national and international propolis standard workings.This work was supported by SBS Bilimsel Bio Cozumler Inc.
