High mortality and residual kidney damage with Coronavirus disease-19-associated acute kidney injury in northern India.

BACKGROUND: Acute kidney injury (AKI) is associated with morbidity and mortality in COVID-19 patients. The incidence of AKI and its outcomes vary in different parts of the world. We aimed to analyze the AKI incidence, predictors of AKI, mortality, and renal function outcomes on follow-up in hospitalized patients with COVID-19. MATERIALS AND METHODS: The study was designed as a retrospective, observational study of electronically captured data on the hospital information system of laboratory-confirmed COVID-19 patients, with and without AKI, between March 2020 to June 2021. The predictor of AKI and mortality and residual damage in recovered AKI patients were analyzed. RESULTS: Of the 3395 patients, 3010 COVID-19 patients were eligible. AKI occurred in 951 (31.5%); with stages 1, 2, and 3 in 605 (63.7%), 138 (14.5%), and 208 (21.8%) patients, respectively. AKI severity increased with COVID-19 severity. Of 951 AKI patients, 403 died, and 548 were discharged. AKI group had higher mortality (42.3%) than the non-AKI (6.6%). At discharge, complete recovery was noticed in 370(67.5%), while 178 (32.5%) had residual damage. At three months of follow-up, 108 (69.6%) of 155 patients showed complete recovery. Residual damage was observed in 47 (30.3%). In 14 (9%) patients, serum creatinine remained elevated above the baseline. Thirty-three (21.2%) patients showed proteinuria (n = 24) and microscopic hematuria (n = 9). CONCLUSIONS: AKI is common among patients hospitalized with COVID-19 and is associated with high mortality. Residual kidney damage post-COVID-19 in recovered AKI patients may increase the CKD burden.

Teledentistry and its applications in paediatric dentistry: A literature review.

BACKGROUND: During the unfortunate event of the COVID-19 pandemic, restrictions were placed on face-to-face interactions in dentistry to promote social distancing and reduce spread of virus. In order to provide dental services teledentistry was employed. OBJECTIVE: This article aims to review the literature and information available on the provision and utilization of teledentistry as a method to address oral health needs of paediatric patients. RESULTS: Teledentistry has been utilised in paediatric population for the purpose of oral health education and promotion, remote diagnosis and monitoring, and behaviour guidance. Studies involving paediatric population for aforementioned applications have shown that this practice strategy is beneficial to provide dental treatment in remote locations with little access to paediatric dental specialists, monitor patients between appointments, conduct remote diagnosis and screening programmes, promote oral health of children through dental education, and in pre-appointment behaviour guidance. This method was particularly useful during the current COVID-19 pandemic where dentists use their mobile phones, computer webcams for patient appointments while maintaining safe distance and avoid exposing themselves as well as patient to the virus. CONCLUSION: Teledentistry can be a supplement to face-to-face methods of paediatric dental care, ultimately leading to better patient management. This technology can make a significant contribution in reducing the supply-demand gap of paediatric dental specialists in places where healthcare facilities are limited and ensure safety during the pandemic whilst providing dental care to paediatric patients. Further research is required for safe, effective and evidence-based use of teledentistry in the field of paediatric dentistry.
