ABSTRACT
BACKGROUND: Coronavirus disease (COVID-19) infection represents a worldwide critical health burden from the sanitary perspective. This disease's symptoms range from a mild flu-like form to a severe life-threatening respiratory disease and respiratory failure. Several patients, however, remain paucisymptomatic. Among the symptoms that seem relevant are the changes in taste and smell, regardless of the disease's severity. METHODS: Data from patients affected by COVID-19 infection, hospitalized from 15 to 29 April, 2020, were analyzed. Questionnaires about smell, taste, and nasal function were administered to all, and a proportion also received the Quick olfactory Sniffin' Sticks Test (q-Sticks) to objectivate the presence of anosmia or hyposmia. The results of instruments and Q-Sticks were then compared. RESULTS: Thirty-seven patients (20 males, 54.1%), with a mean age 0f 69.19 years (SD = 17.96; median 76, IQR: 63-82) were evaluated. Among the patients, 8 (22%) were asymptomatic. Out of the remaining 29 patients, 28 (97%) had fever, 19 (66%) asthenia, 11 (38%) dry cough, 10 (34%) dyspnea, and 6 (21%) gastroenteric symptoms. The q-Sticks test was performed on 27 patients and showed that 6 with anosmia, and 16 patients had hyposmia, where only 5 (14%) patients complained of loss of smell by conducting the questionnaires. CONCLUSION: Although olfactory disturbances may be secondary to other factors, a sudden onset of anosmia or hyposmia should be assessed as a possible symptom of COVID-19 infection. The use of questionnaires or anamnestic collection is sometimes not enough, while adding to them a simple test such as the q-Sticks test can provide more accurate and reliable data. A simple, easy-to-perform, and reliable tool (q-Sticks) for olfactory disorders assessment can be administered to identify the real size of anosmia in patients with COVID-19 infection and detect the early stage of infection or paucisymptomatic patients, therefore becoming important to reduce the spreading of the pandemic.
ABSTRACT
BACKGROUND: A systemic coagulation dysfunction has been associated with COVID-19. In this case report, we describe a COVID-19-positive patient with multisite arterial thrombosis, presenting with acute limb ischaemia and concomitant ST-elevation myocardial infarction and oligo-symptomatic lung disease. CASE SUMMARY: An 83-year-old lady with history of hypertension and chronic kidney disease presented to the Emergency Department with acute-onset left leg pain, pulselessness, and partial loss of motor function. Acute limb ischaemia was diagnosed. At the same time, a routine ECG showed ST-segment elevation, diagnostic for inferior myocardial infarction. On admission, a nasopharyngeal swab was performed to assess the presence of SARS-CoV-2, as per hospital protocol during the current COVID-19 pandemic. A total-body CT angiography was performed to investigate the cause of acute limb ischaemia and to rule out aortic dissection; the examination showed a total occlusion of the left common iliac artery and a non-obstructive thrombosis of a subsegmental pulmonary artery branch in the right basal lobe. Lung CT scan confirmed a typical pattern of interstitial COVID-19 pneumonia. Coronary angiography showed a thrombotic occlusion of the proximal segment of the right coronary artery. Percutaneous coronary intervention was performed, with manual thrombectomy, followed by deployment of two stents. The patient was subsequently transferred to the operating room, where a Fogarty thrombectomy was performed. The patient was then admitted to the COVID area of our hospital. Seven hours later, the swab returned positive for COVID-19. DISCUSSION: COVID-19 can have an atypical presentation with thrombosis at multiple sites.
