COVID-19 Pandemic might be considered as a catalyst for transformation in healthcare experience via the use of video consultation as a method for telemedicine. The aim of our qualitative study is to understand the patient perception of video consultations in telemedicine, which has been used by a single pulmonologist in only one university hospital in Turkey since the first three months of the pandemic. Research findings are essential when it comes to a more effective and widespread future use of telemedicine, as it focuses on patient experience about a medical technology that is newly introduced. Totally 30 patients were randomly chosen and interviewed who get healthcare support via telemedicine. A semi-structured questionnaire was used to learn the experiences and opinions of the interviewees. The expressions of the patients highlight some advantages of using telemedicine such as being free from risk of contagion caused by exposure in the hospital, being able to save time and money while reaching to the physician online whenever needed, and success in technical details even though they were experiencing it for the first time. A very few of the patients are feeling discomfort to be in front of the screen. Almost all patients are applicants to suggest to other individuals the system they used, in conditions to be appropriate, and continuity after the pandemic period. Since the pandemic has propagated from one patient, the worldwide implementation of telemedicine might be catalyzed by following in the footsteps of the sporadic examples of decisiveness nourished from patient experiences.

Objectives: The COVID-19 pandemic is having a major impact on the lives of everyone, but in particular on the health and well-being of older people. It has also disrupted the way that individuals access services and interact with one another, and physical distancing and "Stay at Home" orders have seen digital interaction become a necessity. While these restrictions have highlighted the importance of technology in everyday life, little is known about how older adults have responded to this change. Methods: Two surveys, one in 2019 and another in 2020 collected data on a combined total of 1923 older adults aged 65 years and older in Canada. These looked at how older adults think about and use technology, with the 2020 survey additionally questioning how COVID-19 has impacted their use and attitudes towards technology. Results: While older adults feel more isolated in 2020, many feel positive about the benefits of technology and have increased technology use during the pandemic to support their health, wellness, and communication needs. Discussion: The results highlight the potential of technology for supporting older adults in various aspects of healthy aging. While these results point to the opportunities afforded by technology, challenges remain, such as how social and economic factors influence technology uptake.

Purpose: To compare a self-etch and a two-step etch-and-rinse adhesive in terms of internal and marginal composite-tooth bond failure separately on enamel and dentin/cement at 36-48 months after restoration placement using optical coherence tomography (OCT).

Materials and methods: Twenty-seven patients with two or three class V composite restorations of noncarious cervical lesions 36-48 months after placement were included. The one-step self-etch adhesive Futurabond M ([Voco] group SE, n = 25) and the two-step etch-and-rinse adhesive Solobond M ([Voco] group ER, n = 20) combined with the nanohybrid composite Amaris (Voco) were evaluated. The four-step etch-and-rinse adhesive Syntac classic combined with Tetric EvoCeram (Ivoclar Vivadent) served as the control (n = 18). Spectral-domain OCT (SD-OCT, 1310-nm center wavelength) was applied. Marginal gaps and internal interfacial adhesive defects were quantified in cross-sectional OCT images. Groups were statistically compared using the Friedman/Wilcoxon test (α = 0.05).

Results: In enamel, nonsignificantly different percentages of marginal gap formation and internal interfacial adhesive defects were found between the groups (pi ≥ 0.258). In dentin/cement, SE showed significantly less marginal gap formation compared to ER (p < 0.001) and control (p = 0.001), and at the internal dentin-composite interface less adhesive defects were found compared to ER (p < 0.001) and control (p = 0.003).

Conclusion: The self-etch adhesive used in the current study appears recommendable for restoration of noncarious cervical lesions with composite.

Coronavirus disease 2019 (COVID-19)-related intracranial hemorrhage (ICH) is believed to be associated with at least one known risk factor for ICH, such as hypertension, hyperlipidemia, diabetes mellitus, severe pneumonia, or anticoagulation therapy. However, in this study, we report a case of ICH in a 14-year-old boy with mild COVID-19 infection without pneumonia who had no such risk factors. The only abnormal laboratory finding was temporary depletion of vitamin K-dependent coagulation factors. This case indicates that COVID-19 infection may cause simultaneous asymptomatic intracranial microhemorrhages and temporary depletion of vitamin K-dependent coagulation factors. This temporary depletion might transform the intracranial microhemorrhages into symptomatic ICH.
