Lung computed tomography patterns of a cluster of asymptomatic young males with COVID-19 admitted to a teaching hospital in Kuala Lumpur.

BACKGROUND AND OBJECTIVE: Coronavirus Disease 2019 (COVID- 19) was first reported in Malaysia in March 2020. We describe here the clinical characteristics and computed tomography (CT) patterns in asymptomatic young patients who had laboratory-confirmed COVID-19. METHODS: This is a retrospective observational study where 25 male in-patients with laboratory-confirmed COVID-19 in Hospital Canselor Tuanku Muhriz. Demographics, clinical data and CT images of these patients were reviewed by 2 senior radiologists. RESULTS: In total there were 25 patients (all males; mean age [±SD], 21.64±2.40 years; range, 18-27 years). Patients with abnormal chest CT showed a relatively low normal absolute lymphocytes count (median: 2.2 x 109/L) and absolute monocyte count (median: 0.5 x 109/L). Lactate dehydrogenase was elevated in 5 (20%) of the patients. The procalcitonin level was normal while elevated levels of alanine aminotransferase, total bilirubin, platelet and C-reactive protein were common. Baseline chest CT showed abnormalities in 6 patients. The distribution of the lesions were; upper lobe 3 (12%) lower lobe 3 (12%) with peripheral distribution 4 (16%). Of the 25 patients included, 4 (16%) had ground glass opacification (GGO), 1 (4%) had a small peripheral subpleural nodule, and 1 (4%) had a dense solitary granuloma. Four patients had typical CT features of COVID-19. CONCLUSION: We found that the CT imaging showed peripheral GGO in our patients. They remained clinically stable with no deterioration of their respiratory symptoms suggesting stability in lung involvement. We postulate that rapid changes in CT imaging may not be present in young, asymptomatic, non-smoking COVID-19 patients. Thus the use of CT thoraxfor early diagnosis may be reserved for patients in the older agegroups, and not in younger patients.

Prospective Study of Functional Recovery of Stroke Patients at Three Months Post Admission: Outcomes and Implications for Post Stroke Care Provision

Functional recovery in the immediate post stroke period predicts the long-term prognosis of post stroke patients. Despite the advancement in stroke rehabilitation in improving the physical function of survivors, there are other factors that may influence functional recovery. We aimed to assess the functional recovery of ischaemic stroke patients attending a tertiary hospital and its associated factors in order to make recommendations for post stroke care after hospital admission. A three months prospective observational study looking at functional recovery using the Modified Barthel’s Index (MBI) and depression (Patient Heath Questionnaire-9)score of post stroke patients. There were 46 ischaemic stroke patients who were recruited for the study. At three months, only 37 patients were eligible for analysis. The mean age was 67.2 (SD 11) years with the Malays (50%) making up the majority of the patients, followed by Chinese (41.3%) and Indians (8.7%). There was a total of seven (15.2%) deaths. Hypertension was the most common risk factor (89.1%) followed by dyslipidaemia (65.2%) and diabetes mellitus(63.0%). The mean MBI difference was 45.2 (SD 27.0) with a median MBI of 17.0(IQR 33.0) at baseline compared to 85.0(IQR 42.0) at three months (p < 0.001, CI 35.98,55.45). The prevalence of depression (PHQ-9≥10) was 21.6%. Lower functional recovery was found among depressed patients (p <0.026) and among patients with recurrent stroke (p< 0.035). Significant functional recovery can be seen as early as threemonths post stroke. Factors such as recurrent stroke and depression may affect functional recovery post stroke; hence should be routinely screened.
