Maxillofacial infections in post covid-19 era: A series of 2 cases

Everybody in the world including the health care sector has witnessed the devastating effects of COVID- 19 infection. It is an enigma to say whether COVID -19 has gone for good or not, but has definitely presented as a challenge in itself for dental professionals. Complications have escalated especially at the end of the 2nd wave, probably due to various immunosuppressant drugs that have been used for it's aggressive treatment. These cases highlights osteomyelitis of maxilla and surrounding structures in patients due raised levels of blood sugar and also due to steroidal therapy. Recent reports that have been published, show a rate of approximately 80.76% of such cases in maxilla, out of which 61.53% patients were found to be diabetic before diagnosis. These cases presents post COVID-19 osteomyelitis which is believed to be triggered by highly raised blood sugar levels in a patient who was not a known case of diabetes mellitus.

CoviBlock: A Secure Blockchain-Based Smart Healthcare Assisting System

The recent COVID-19 pandemic has underlined the significance of digital health record management systems for pandemic mitigation. Existing smart healthcare systems (SHSs) fail to preserve system-level medical record openness and privacy while including mitigating measures such as testing, tracking, and treating (3T). In addition, current centralised compute architectures are susceptible to denial of service assaults because of DDoS or bottleneck difficulties. In addition, these current SHSs are susceptible to leakage of sensitive data, unauthorised data modification, and non-repudiation. In centralised models of the current system, a third party controls the data, and data owners may not have total control over their data. The Coviblock, a novel, decentralised, blockchain-based smart healthcare assistance system, is proposed in this study to support medical record privacy and security in the pandemic mitigation process without sacrificing system usability. The Coviblock ensures system-level openness and trustworthiness in the administration and use of medical records. Edge computing and the InterPlanetary File System (IPFS) are recommended as part of a decentralised distributed storage system (DDSS) to reduce the latency and the cost of data operations on the blockchain (IPFS). Using blockchain ledgers, the DDSS ensures system-level transparency and event traceability in the administration of medical records. A distributed, decentralised resource access control mechanism (DDRAC) is also proposed to guarantee the secrecy and privacy of DDSS data. To confirm the Coviblock's real-time behaviour on an Ethereum test network, a prototype of the technology is constructed and examined. To demonstrate the benefits of the proposed system, we compare it to current cloud-based health cyber-physical systems (H-CPSs) with blockchain. According to the experimental research, the Coviblock maintains the same level of security and privacy as existing H-CPSs while performing considerably better. Lastly, the suggested system greatly reduces latency in operations, such as 32 milliseconds (ms) to produce a new record, 29 ms to update vaccination data, and 27 ms to validate a given certificate through the DDSS.

Urologic Education in the Era of COVID-19: Results From a Webinar-Based Reconstructive Urology Lecture Series.

OBJECTIVE: To determine the response to a virtual educational curriculum in reconstructive urology presented during the COVID-19 pandemic. To assess learner satisfaction with the format and content of the curriculum, including relevance to learners' education and practice. MATERIALS AND METHODS: A webinar curriculum of fundamental reconstructive urology topics was developed through the Society of Genitourinary Reconstructive Surgeons and partnering institutions. Expert-led sessions were broadcasted. Registered participants were asked to complete a survey regarding the curriculum. Responses were used to assess the quality of the curriculum format and content, as well as participants' practice demographics. RESULTS: Our survey yielded a response rate of 34%. Survey responses showed >50% of practices offer reconstructive urologic services, with 37% offered by providers without formal fellowship training. A difference in self-reported baseline knowledge was seen amongst junior residents and attendings (P < .05). Regardless of level of training, all participants rated the topics presented as relevant to their education/practice (median response = 5/5). Responders also indicated that the curriculum supplemented their knowledge in reconstructive urology (median response = 5/5). The webinar format and overall satisfaction with the curriculum was highly rated (median response = 5/5). Participants also stated they were likely to recommend the series to others. CONCLUSION: We demonstrate success of an online curriculum in reconstructive urology. Given >50% of practices surveyed offer reconstruction, we believe the curriculum's educational benefits (increasing access and collaboration while minimizing the risk of in-person contact) will continue beyond the COVID-19 pandemic and that this will remain a relevant educational platform for urologists moving forward.
