Purpose We assessed the effects of COVID-19 infection on nasal mucociliary activity. Methods The study was conducted in the pandemic wards of Adiyaman University Training and Research Hospital during April and May 2020. All patients admitted to the COVID-19 pandemic wards during the study period were invited to participate in the study. The study included 40 adults who agreed to participate and underwent a mucociliary clearance test successfully. The primary outcome was mucociliary clearance time and the secondary variables of interest were age, sex, and sino-nasal outcome test-22 scores. The control group included 40 concomitant healthy patients who visited the outpatient ear, nose and throat clinic with non-nasal symptoms. Results The study included 40 COVID-19-positive patients and 40 healthy controls. The mean mucociliary clearance times of the study (15.53 ± 5.57 min) and control (9.50 ± 3.70 min) groups were significantly different (Z = 4.675, p < 0.001). However, the mucociliary clearance time was not significantly different between males and females (t = 0.590, p = 0.558). Conclusions Nasal mucociliary clearance time was prolonged in COVID-19 patients compared to healthy controls. Thus, we conclude that smell and taste are crucial symptoms that should not be overlooked in patients suspected of COVID-19 disease.

The triglyceride-glucose (TyG) index is calculated from fasting triglycerides and fasting glucose levels and is an indicator of insulin resistance. The present study investigates whether the TyG index has a role in predicting clinical outcomes in cases of acute coronary syndrome (ACS). This retrospective study included 646 patients with ST-elevation myocardial infarction (STEMI) and 1048 patients with non–ST-elevation myocardial infarction (NSTEMI). The association between major adverse cardiac events (MACEs) that developed in-hospital and at 60 months of follow-up and TyG index values were compared. Patients were divided into 2 groups: TyG index values of ≥8.65 and <8.65. During the hospital stay and 60 months of follow-up, 303 MACEs occurred. In both the STEMI and NSTEMI groups, as the TyG index increased, an increase was observed in MACE rates. MACE rates were also found to be highest in the group with TyG index ≥8.65 ( P < .001). TyG index, C-reactive protein, and age were independent predictors of MACEs in both the NSTEMI and STEMI groups. The present study found a significant association between higher TyG index values and increased risk of MACEs in ACS patients. The TyG index may prove useful to predict clinical outcomes in ACS patients.

Background: It is known that a wide frontal QRS‐T(f[QRS‐T]) angle in the electrocardiography (ECG) is associated with poor cardiovascular outcomes. The Tp‐e (the interval from the peak to the end of the T wave) interval and Tp‐e/QTc ratio show the dispersion of repolarization, and increased levels lead to ventricular arrhythmogenesis in congenital channelopathies and coronary heart disease. In this study, we aimed to investigate the relationship between f(QRS‐T), Tp‐e interval, and Tp‐e/QTc ratio and SYNTAX score in stable coronary artery disease (SCAD) patients.Methods: A total of 403 patients who performed coronary angiography for SCAD were included. The study population was divided into two groups based on the SYNTAX score. Group 1 included 248 patients (high SYNTAX score > 0), and group 2 included 155 patients (low SYNTAX score = 0). SYNTAX score was calculated using an online SYNTAX score calculator from the coronary angiography images of each patient. The f(QRS‐T) angle (QRS angle minus T angle) was calculated from the automated reports of the 12‐lead ECG device. Tp‐e interval and Tp‐e/QTc ratio and other electrocardiographic parameters were recorded.Results: The mean SYNTAX score in group 1 was 8. F(QRS‐T) angle, Tp‐e duration, Tp‐e/QT, and Tp‐e/QTc were significantly higher in group 1 compared with group 2. In the multivariate regression analysis, F(QRS‐T) angle and Tp‐e duration were independent predictors for SYNTAX scores in SCAD patients.Conclusions: Our study showed that Tp‐e interval, Tp‐e/QTc ratio, and f(QRS‐T) angle were increased in patients with higher SYNTAX scores in patients with SCAD patients.

Primary malignant melanoma of the nose and paranasal sinus mucosa is a rare disease and seen in less than 1% among all melanomas. Malignant melanomas have 2 origins: cutaneous and mucosal. The mucosal form has a worse prognosis because of its aggressiveness compared with that of the cutaneous form. Mucosal melanomas often occur at a rate of 2% to 3% among all melanomas and are typically found in the nasal cavity and paranasal sinuses. Generally, it is more common in males and in those older than 50 years. In this study, 4 patients were observed at the Cumhuriyet University Faculty of Medicine; 2 of them were a 64-year-old man and an 82-year-old woman who had a malignant melanoma originating from the nasal septal mucosa, 1 patient was a 72-year-old woman whose malignant melanoma originated from the inferior turbinate, and 1 patient was a 77-year-old woman with a sinonasally located melanoma. The conditions of these patients were discussed under the light of literature instructions.
