Value of baseline radiograph for COVID-19 infected patients

Introduction: A cluster of pneumonia cases of unknown origin was first reported in Wuhan China then the causative pathogen was identified and named severe acute respiratory syndrome coronavirus 2 (SARS-Cov2) and the associated disease was named coronavirus disease 2019 (COVID-19). Chest radiograph has lower sensitivity for the detection of lung abnormalities but it has a role in disease progression and also in the late stages of COVID19. This study aims to evaluate the value of baseline radiographs in COVID-19-infected patients. Method: This is a retrospective study of COVID-19 patients with RT-PCR confirmation who were admitted to Eka Kotebe General Hospital and had baseline chest x-ray between April and May 2020. Baseline chest x-ray of all patients who have confirmed COVID-19 infection was reviewed and analyzed. Result: The study included 355 patients, 224 (63.1%) were male and 131 (36.9%) were female. Patient age ranged from 4 - 82 years with a mean age of 35. Two hundred twelve patients were symptomatic; the rest 143 were asymptomatic. Of the 355 baseline CXR, only 60 (16.9%) had abnormal radiographs and the rest 295 (83.1%) had normal radiographs. A combination of interstitial changes and GGO were the predominant descriptive finding accounting for 33.3% . Conclusion: Even if chest radiographs are important in the workup of patients with COVID-19 infection, the use of baseline radiographs in COVID-19 infection should not be a routine practice. Disease severity and timing of imaging appear to impact the rates of normal baseline imaging.

COVID-19 infection prevention preparedness, practices and case management in the primary health care units in Ethiopia

BACKGROUND: COVID-19 as pandemic declared by WHO on March 11, 2020 and first case detected in Ethiopia on March 13/2020. The COVID-19 caused a global crisis, including millions of lives lost, public health systems in shock and economic and social disruption. Strategies depend on how an existing health system is organized. Even though public health emergency operation centers of the Ethiopia switched to emergency response, there is no national evidence about infection prevention and control. Therefore, this project aimed to assess the level of infection prevention and control and management of COVID- 19 in Ethiopia, 2021. METHODS: The cross-sectional study conducted at four regions and one city (Amhara, Oromia, SNNPR, Sidama Region, and Dire Dawa). Being with zonal health departments and woredas health offices, primary health care units were selected. The data were collected electronically through Kobocollect software from November 08-28/2021. Descriptive analysis like frequency and percentage was conducted by SPSS software version 25 and the results were presented by tables, figures and narration. RESULTS: Data were collected from 16 hospitals, 92 health centers, and 344 health posts. All hospitals have designated COVID-19 focal person. There were significant number of woredas and PHCUs who didn't have IPC guidelines and protocols. About 11 woredas had no any type of diagnostic tests for COVID-19. CONCLUSIONS: The study revealed that there were significant gaps on Infection prevention and control practice, shortage of personal protective equipment, isolation and specimen transportation problem, lack of call centers. We recommend concerned bodies to fill the identified gaps.

Radiology residents' perception of working and training from home during covid-19 pandemic

Introduction: The spread of coronavirus disease 2019 (COVID-19) pandemic disrupted the personal and profes-sional lives of many throughout the world. To mitigate the spread of the virus, Addis Ababa University introduced an online teaching/learning method which minimized the physical engagement of faculty members and residents. Online teaching is a major shift in the history of the country's oldest and largest university. Objectives: This study aimed to investigate how trainees managed to cope up with the sudden changes in the teach-ing/learning system, and assess the ensuing satisfaction with the new method of teaching/learning. Methods: Descriptive research design was implemented and analysis of variance (ANOVA) and T-tests were used to test hypotheses. Analysis of data collected from 58 radiology residents found that, the residents appreciated the participatory nature of the newly introduced online learning method. Results: The results showed that residents have accepted the new teaching/learning method and are satisfied with it. Furthermore, tests of hypotheses revealed that there is no significant difference in level of satisfaction between female and male residents as well as throughout the three years of radiology residency training. Conclusion: The new method of teaching/learning has a positive acceptance among trainees and there was high level of satisfaction with the new method. Poor internet network, reduced in-person mentoring, failure to make engaging discussions due to large number of participants were the common challenges to online teaching in the setting.

The value of ultrasound in characterizing and determining the etiology of ascites

BACKGROUND: The aim of this study was to assess the role of transabdominal ultrasonography in characterizing and determining the etiology of ascites in comparison with laboratory ascitic fluid analysis and other methods used to establish the final diagnosis. METHODS: A prospective descriptive study was conducted on 61 patients with ascites attending outpatient department (OPD) or admitted to wards of Tikur Anbesa Specialized Hospital (TASH) and referred to radiology department for imaging from June 2017 to November 2017. Data were collected following the internationally recommended scanning technique in consecutive bases. The data were analyzed using SPSS version 20. The comparison of ultrasound and laboratory findings with final clinical diagnosis was analyzed using Chi-square test (X2). RESULTS: Of 61 patients with ascites enrolled in this study, females were 35(57.4%) with age range of 16 to 75 and mean age of 43.2±14.11. The cause of ascites was established in 59 cases using a combination of clinical, pathological, imaging evidences and tumor markers. However there were two cases who had ascites with indeterminate cause. US suggested the diagnosis in 54(91.5%) patients. Excluding mixed and indeterminate cases, ultrasound characterized ascites correctly as exudate and transudate in 95% cases. CONCLUSION: Ultrasound has significant accuracy to distinguish transudate and exudate ascites and in suggesting the underlying cause. It can be a valuable method of investigation of ascites in places where CT and MRI are not available, and it is the best complement for laboratory investigations on ascites in suggesting the etiology based on ascitic fluid texture and ancillary findings
