ABSTRACT
Objectives: The aim of this study was to investigate the pulmonary function of pediatric patients with COVID-19 after recovery. Methods: Pediatric patients aged 5-18 years hospitalized with diagnoses of COVID-19 and discharged with recovery were included in this prospective study. Pulmonary function tests (PFTs) were performed through spirometry. Results: The patient group consisted of 34 children and the control group of 33. The forced vital capacity (FVC%) values of the control and patient groups were 110.62±11.71 and 94.21±13.68 (p<0.001), forced expiratory volume in the first second (FEV1%) values were 104.91±6.26 and 98.67±14.93 (p=0.032), FEV1/FVC% values were 108.50±8.81 and 101.06±24.89 (p=0.034), and forced expiratory flow (FEF) 25-75% values were 106.71±6.68 and 101.85±24.89, respectively (p=0.286). However, Spearman correlation analysis revealed moderate negative correlation between length of hospital stay and FEF 25-75% (r=-0.364, p=0.35). Conclusion: PFTs in pediatric patients after recovery from COVID-19 were abnormal in the present study. The results were significant in terms of the development of mixed-type lung disease. Further long- and short-term studies are now needed for a better understanding of the prognosis in these patients.
ABSTRACT
OBJECTIVE: Hand hygiene, one of the most critical preventive methods against Coronavirus Disease-2019 (COVID-19) cross-transmission, has increased during the COVID-19 outbreak. The present study aims to investigate the prevalence and risk factors of hand eczema (HE) and associated symptoms in healthcare workers (HCWs) during the COVID-19 outbreak. METHODS: We distributed a self-administered online survey to physicians and nurses in Kahramanmaras, Turkey. The survey included questions about HE-associated symptoms and risk factors before and during the pandemic. RESULTS: Five hundred sixty-four individuals (349 physicians and 215 nurses) answered the survey. Post-COVID-19, the prevalence of HE increased from 6.6% to 11.7% and the prevalence of HE-associated symptoms increased from 39.5% to 79.3%. Female gender (odds ratio [OR]: 3.92; 95% confidence interval [CI]: 2.12-7.25), a history of atopic diseases (OR: 1.7; 95% CI: 1.03-2.8), more frequent handwashing (OR: 1.03; 95% CI: 1.01-1.05), and more frequent use of moisturizers (OR: 1.12; 95% CI: 1.01-1.24) were independently associated with the risk of HE-associated symptoms. CONCLUSION: Because of increased handwashing during the COVID-19 outbreak, there is a significant increase in HE-associated symptoms in HCWs. Proper education and preventive strategies for HE are urgently needed for HCWs fighting on the front lines of COVID-19.
ABSTRACT
A new type of coronavirus named as SARS-CoV-2 pandemic has begun to threaten human health. As with other types of coronaviruses, SARS-CoV-2 affects children less frequently, and it has been observed that the disease is mild. In the pathogenesis of a standard viral infection, the pathogen's contact with the mucosa is initially followed by an innate immunity response. T cells are the primary decisive element in adaptive immunity capability. For this reason, the adaptive immune response mediated by the thymus is a process that regulates the immune response responsible for preventing invasive damage from a virus. Regulatory T cells (T-reg) are active during the early periods of life and have precise roles in immunomodulation. The thymus is highly active in the intrauterine and neonatal period; it begins to shrink after birth and continues its activity until adolescence. The loss of T-reg function by age results in difficulty with the control of the immune response, increased inflammation as shown in coronavirus disease (COVID-19) as an inflammatory storm. Also, the thymus is typically able to replace the T cells destroyed by apoptosis caused by the virus. Thymus and T cells are the key factors of pathogenesis of SARS-CoV-2 in children.Conclusion: We speculated that thymus activity and T lymphocyte function in children protect them against the virus effects. Stimulating and preventing the inhibition of the thymus can be possible treatment components against COVID-19. What is Known: ⢠The SARS-CoV-2 infection does not often progress with an invasive clinic in children. ⢠Thymus activity and T lymphocyte functions are highly active in children. What is New: ⢠Effective thymus activity and T lymphocyte function in children protect them against the invasive SARS-CoV-2 infection. ⢠Stimulating and preventing the inhibition of the thymus can be possible treatment components against COVID-19.
