The diagnostic performance of chest computed tomography scanning in the diagnosis of coronavirus disease 2019 compared to polymerase chain reaction: A retrospective study of 1240 cases from Tripoli University Hospital, Libya

OBJECTIVE: The increasing prevalence of suspected cases of coronavirus disease 2019 (COVID-19) presenting to emergency departments (EDs) requires a rapid and reliable triaging tool. The diagnostic performance of chest computed tomography (CT) has yet to be validated for triaging cases in the ED. We aimed to assess the diagnostic performance of chest CT compared to GeneXpert Xpress Xpert severe acute respiratory syndrome coronavirus 2 test in rapidly diagnosing COVID-19 among patients with respiratory symptoms presenting to the ED. MATERIALS AND METHODS: This was a retrospective, single-center study at Tripoli University Hospital including cases with respiratory symptoms who underwent chest CT as well as polymerase chain reaction (PCR) testing for suspected COVID-19 between May 18 and August 18, 2020. RESULTS: A total of 1240 cases were included, among whom 570 had radiologically evident COVID-19 on chest CT (46%). Five hundred and sixty-five cases had positive PCR results (45.6%), of whom 557 had radiologically evident COVID-19 on chest CT (97.7%). The calculated accuracy, sensitivity, specificity, positive predictive value, and negative predictive value were 98%, 98.5%, 98%, 97.7%, and 98.8%, respectively, in relation to the PCR results. CONCLUSION: During the current pandemic, chest CT is a quick and reliable diagnostic tool for COVID-19 in the ED.

Prevalence, pattern, and attitudes of smoking among libyan diabetic males: A clinic-based study

Introduction: Smoking is a major avoidable cardiovascular risk factor and is a cause of premature death worldwide. Objectives: To study the prevalence, pattern, and awareness of health hazards of smoking among Libyan diabetic male patients in Tripoli Medical Center, Tripoli, Libya. Patients and Methods: A cross-sectional, clinic-based study using a predesigned questionnaire, the participants were interviewed by the author. The interview covered personal data, and questions about their smoking status, and their awareness of smoking hazards. Results: The overall prevalence of current smoking was 26.4% and past smoking 40.3%. The mean age was 50.8 ± 14.4 years (range 18–75 years). The mean age at which smoking started was 18.6 ± 5.3 years; all current smokers were cigarette smokers. Main reason for quitting smoking was related to health issues while social and religious considerations were the main reasons for never smoking. Conclusions: The prevalence of smoking among Libyan diabetic patients was high; this calls for incorporating smoking cessation services within the diabetes care clinics

Takayasu's arteritis in a Libyan female

Takayasu’s arteritis (TA) is a large‑vessel vasculitis that involves the aorta and its major branches. Renal arteries are frequently involved, usually with renovascular hypertension. The prevalence of TA in Arabs is low. A study of the epidemiological and clinical features of TA in Arabs included 197 identified patients between 1995 and 2012 and none of them was Libyan. We report a 61‑year‑old Libyan woman in whom TA manifested with hypokalemia and arterial hypertension. Previous ultrasound showed renal size asymmetry raised the possibility of renal artery stenosis. The diagnosis of TA was confirmed by magnetic resonance angiography, which showed a thickened abdominal aortic wall, occlusions of the left renal artery and left common iliac artery, stenosis of the right common iliac artery, and stenosis of both subclavian arteries. TA is rarely encountered in Arabs. However, the disease must be considered in patients who present with renovascular hypertension, in a context of other autoimmune disorders. arabic 6 English 33
