The dynamics, such as transmission, spatial epidemiology, and clinical course of Coronavirus Disease-2019 (COVID-19) have emerged as the most intriguing features and remain incompletely understood. The genetic landscape of an individual in particular, and a population in general seems to play a pivotal role in shaping the above COVID-19 dynamics. Considering the implications of host genes in the entry and replication of SARS-CoV-2 and in mounting the host immune response, it appears that multiple genes might be crucially involved in the above processes. ⋯ Host-pathogen interaction is a complex event and some additional genes might also contribute to the dynamics of COVID-19. Overall, these three genetic gateways proposed here might be the critical host determinants governing the risk, severity, and outcome of COVID-19. Genetic variations within these gateways could be key in influencing geographical discrepancies of COVID-19.

ReviewEvidence-Based Guidelines for Management of Head and Neck Mucosal Malignancies during the COVID-19 Pandemic.
Due to the current coronavirus disease 2019 (COVID-19) pandemic, otolaryngologists face novel challenges when treating patients with head and neck cancer. The purpose of this review is to evaluate the current evidence surrounding the treatment of these patients during this pandemic and to provide evidence-based recommendations with attention to increased risk in this setting. ⋯ Patient care plans should be guided by best available evidence to optimize outcomes while maintaining a safe environment in the setting of this pandemic.

According to the World Health Organization (WHO) the China office was first notified of cases of atypical pneumonia in Wuhan City on 31 December 2019. A viral genome sequence of a novel coronavirus, currently termed SARS-CoV‑2, with a disease process called COVID-19 was released 1 week later via online resources to obtain public health support in control of spread. Since then, the virus rapidly evolved into a global pandemic. ⋯ Currently, treatment is supportive. Researchers are working to develop vaccines and identify effective antiviral interventions. Those recently discussed in the literature are briefly reviewed.

ReviewSevere respiratory SARS-CoV2 infection: Does ACE2 receptor matter?
SARS-CoV-2 is a novel virus of the Coronaviridiae family that represents a major global health issue. Mechanisms implicated in virus/host cells interaction are central for cell infection and replication that in turn lead to disease onset and local damage. ⋯ Molecular mechanisms that promote interaction between SARS-CoV-2 virus and host with particular focus on virus cell entry receptor ACE2 are described. We further explore the impact of underlying medical conditions and therapies including renin-angiotensin inhibitors on modulating ACE 2, which is the major SARS-CoV-2 cell entry receptor.

Case Reports
Weakness and elevated creatinine kinase as the initial presentation of coronavirus disease 2019 (COVID-19).
COVID-19 is a global public health emergency with more than one million positive cases across the globe. COVID-19 has a multifaceted presentation. We are herein to report two cases of SARS-CoV-2 induced rhabdomyolysis with an initial presentation of weakness and elevated creatinine kinase (CK). ⋯ Routine chest X-ray showed bilateral infiltrates in both cases and subsequently reverse-transcription polymerase chain reaction (RT-PCR) for SARS-CoV-2 was positive. To the best of our knowledge, there was only one literature to date documented SARS-CoV-2 induced rhabdomyolysis as a late complication of COVID-19 patient. Our cases showed that elevated CK and rhabdomyolysis can be the sole initial presentation of patients with COVID-19 and total CK should be ordered in every patient on admission.
