Comparison of clinical characteristics and outcomes of hospitalized patients with seasonal coronavirus infection and COVID-19: a retrospective cohort study.

BACKGROUND: Unlike SARS-CoV and MERS-C0V, SARS-CoV-2 has the potential to become a recurrent seasonal infection; hence, it is essential to compare the clinical spectrum of COVID-19 to the existent endemic coronaviruses. We conducted a retrospective cohort study of hospitalized patients with seasonal coronavirus (sCoV) infection and COVID-19 to compare their clinical characteristics and outcomes. METHODS: A total of 190 patients hospitalized with any documented respiratory tract infection and a positive respiratory viral panel for sCoV from January 1, 2011, to March 31, 2020, were included. Those patients were compared with 190 hospitalized adult patients with molecularly confirmed symptomatic COVID-19 admitted from March 1, 2020, to May 25, 2020. RESULTS: Among 190 patients with sCoV infection, the Human Coronavirus-OC93 was the most common coronavirus with 47.4% of the cases. When comparing demographics and baseline characteristics, both groups were of similar age (sCoV: 74 years vs. COVID-19: 69 years) and presented similar proportions of two or more comorbidities (sCoV: 85.8% vs. COVID-19: 81.6%). More patients with COVID-19 presented with severe disease (78.4% vs. 67.9%), sepsis (36.3% vs. 20.5%), and developed ARDS (15.8% vs. 2.6%) compared to patients with sCoV infection. Patients with COVID-19 had an almost fourfold increased risk of in-hospital death than patients with sCoV infection (OR 3.86, CI 1.99-7.49; p < .001). CONCLUSION: Hospitalized patients with COVID-19 had similar demographics and baseline characteristics to hospitalized patients with sCoV infection; however, patients with COVID-19 presented with higher disease severity, had a higher case-fatality rate, and increased risk of death than patients with sCoV. Clinical findings alone may not help confirm or exclude the diagnosis of COVID-19 during high acute respiratory illness seasons. The respiratory multiplex panel by PCR that includes SARS-CoV-2 in conjunction with local epidemiological data may be a valuable tool to assist clinicians with management decisions.

An overlooked cause of septic shock: Staphylococcal Toxic Shock Syndrome secondary to an axillary abscess.

Staphylococcal Toxic Shock Syndrome (TSS) is characterized by rapid onset of fever, rash, hypotension, and multiorgan system involvement. Clinical manifestations of staphylococcal TSS include fever, chills, hypotension, and a diffuse macular erythroderma followed by desquamation one to two weeks later. The disease came to public attention in the 1980s with the occurrence of a series of menstrual-associated cases. However, the relative incidence of staphylococcal TSS not associated with menstruation has increased, and still, it remains an overlooked cause of septic shock. We present the case of a healthy 19-year-old male that presented with fever, chills, malaise, near-syncope, and a non-fluctuant, mobile nodule in the left armpit. The patient developed septic shock requiring critical care. He underwent extensive investigations resulting negative except for PCR for the detection of MRSA, raising the suspicion for STSS. For that reason, antibiotics for staphylococcal coverage were started, after which he started to improve. Ultimately, the mobile nodule evolved to fluctuant access. Incision and drainage was performed, and cultures confirmed the presence of Staphylococcus aureus.

MMR Vaccine Adverse Drug Reactions Reports in the CDC WONDER System, 1989-2019.

Dissemination of misleading information regarding vaccine safety has contributed to the reduction in vaccination rates and the resurgence of diseases once considered eliminated. The CDC WONDER interface can be used to perform simple but powerful safety analyses and counter misinformation. The dissemination of false and misleading information regarding vaccine adverse reactions online has led to negative consequences, including raising parents' concerns about vaccine safety and fostering a growing opposition to the use of vaccines. However, health care workers can also use online resources to counter misinformation. The Centers for Disease Control and Prevention Wide-ranging Online Data for Epidemiologic Research (CDC WONDER) is an online interface that allows health care workers to access the large-linked electronic health record database Vaccine Adverse Event Reporting System and perform near real-time vaccine safety analyses; hence it has the potential to become a powerful and accessible tool to provide information-driven decision-making regarding vaccine safety.
