Although people with less critical symptoms should not visit hospitals in order to reduce exposure during a pandemic, it is of utmost importance that those experiencing risky symptoms visit in early stages to prevent delayed consequences. In this article, we reported three ST-segment Elevation Myocardial Infarction (STEMI) patients who would have benefited from visiting the hospital earlier while they were experiencing low threshold angina.

Acne vulgaris is a very common dermatologic disease. Here, we reported at least two cases of facial acne vulgaris exacerbation during the pandemic of coronavirus disease 2019 (COVID-19). Also, during the other respiratory disaster due to the severe acute respiratory syndrome coronaviru (SARS)in Singapore, skin reactions and complications of the personal protective equipment (PPE) were assessed. Acne was the most common complication of N95 masks. In China, where the COVID-19 has begun, the exacerbation of previous facial dermatoses was asked and the most exacerbated dermatoses after rosacea was acne. Two justifications for the exacerbation of acne have been proposed: first, the humid tropical microclimate created by the mask on the facial skin, which can induce acne and the second is local pressure of the mask on the face, which may cause pressure-induced obstruction of the  infundibulum of hair follicles. Dermatologists should expect exacerbations of acne in many patients during the respiratory epidemic and educate their patients.

The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is now a global threat. Various papers have addressed the pulmonary symptoms of this viral disease. Also, thrombotic complications have been highly prevalent among COVID-19 patients. Reports on rare presentations of COVID-19 can help fast diagnosis and management. In this study, a COVID-19 patient is presented who developed mesenteric ischemia.

Coronavirus disease 2019 (COVID-19) has become the most important challenge for health care worldwide. COVID-19 can be presented as an asymptomatic infection primarily or entirely, which plays a critical role in human-to-human transmission. This issue poses a huge challenge to the patients seeking care in the Emergency Department (ED).

We described the incidental diagnosis of COVID-19 among 11 patients referring to the ED due to the complaints not in favor of COVID-19. All patients had lung involvements in their chest computed tomography scan, and positive reverse transcriptase-polymerase chain reaction test.

It is suggested that during the COVID-19 outbreak, all the staff in the ED must be extremely cautious and deploy recommended personal protective equipment regardless of the patient’s primary complaint. All patients and their family members must be protected against any suspicious contacts while visiting the ED.

Background: The most common symptom of the novel Coronavirus Disease 2019 (COVID-19) infection is fever and dyspnea that leads to hypoxia in severe cases. Some COVID-19 patients experience neurological symptoms, including ischemic stroke and intracerebral hemorrhage. Sickle Cell Disease (SCD) is a hypercoagulable state, however, it has not been approved as a significant cause of Cerebral Venous Thrombosis (CVT). 

Case presentation: In this case report, we described CVT in an SCD patient who had COVID-19, as well. We reported a 32-year-old man with a history of sickle cell anemia presented with left hemiparesis, headache, and seizure. After evaluation of the patient, CVT accompanied by COVID-19 infection was diagnosed. He was treated with intravenous unsaturated heparin, antiepileptic drugs, and antiviral agents with a favorable outcome. Based on our knowledge, this is the first case study to describe an association between CVT and COVID-19 infection in a patient with SCD.

Conclusion: During the recent pandemic, vaso-occlusive attacks in SCD patients can be evaluated for COVID-19 as an etiological factor.

In recent months, coronavirus disease 2019 (COVID-19) is a significant global health problem that has a tremendous negative impact on the human being, and almost all countries of the world have been affected by the disease. CT imaging techniques have an important role in the primary diagnosis of pneumonia secondary to COVID-19; moreover, the level of pulmonary involvement in CT scan is one of the criteria for disease severity in the acute phase of COVID-19 pneumonia. Still, the role of CT scan in the follow-up period is unknown.
