We describe the clinical, laboratory and radiological features of 3 critically ill patients with COVID-19 who developed severe encephalopathy. The first patient did not regain consciousness when sedation was removed at the end of 2 weeks of intensive care. He had received treatment with convalescent plasma. His clinical examination was remarkable for intact brainstem reflexes, roving eye movements, later transient ocular flutter; and then what appeared to be slow ocular dipping. He had no coherent volitional response to the environment. The second patient recovered with measurable cognitive deficits after a prolonged period of encephalopathy. He had received combination treatment with interferon beta 1b and lopinavir/ritonavir. The third patient remained in persistent, severe agitated delirium and died 3 months into his illness. The MRI of the 3 patients showed multifocal abnormalities predominantly in the cerebral white matter, with varying involvement of the grey matter, brainstem and spinal cord. Case 1's MRI changes were consistent with acute disseminated encephalomyelitis. The patients also displayed blood markers, to varying degree, of autoimmunity and hypercoagulability. We were not able to convincingly show, from microbiological as well as immunological evaluation, if the effects of COVID-19 on these patients' nervous system were a direct consequence of the virus, proinflammatory-thrombotic state or a combination. Patient 1 responded partially to empirical, albeit delayed, therapy with intravenous immunoglobulins. Patient 2 recovered with no specific treatment. These cases illustrate the need to understand the full spectrum of encephalopathy associated with COVID-19 so as to better guide its management.

IntroductionRetrocaval ureter is a rare congenital anomaly with the ureter passage posterior to the inferior vena cava. Surgical repair is suggested for patients with significant functional obstruction. However, there is little literature to suggest the management of asymptomatic patients.Case presentationCase 1 patient is a 29 year-old Indonesian man and case 2 patient is a 41 year-old Malay man. Both patients were asymptomatic and well.DiscussionThis report is the short follow-up, therefore making it impossible to elucidate the natural history of uncorrected retrocaval ureters.ConclusionAt 8 month and 6 month respectively, they remained well without symptoms. Our report suggests that immediate surgical repair is not always needed. Longer follow-up with larger patient population is needed to formally elucidate the natural history of this uncommon condition.

We present a rare case of rectosigmoid malakoplakia treated with fluoroquinolone.

Neurological diseases including stroke and neurodegenerative disorders cause a hefty burden on the healthcare system. Survivors experience significant impairment in mobility and daily activities, which requires extensive rehabilitative interventions to assist them to regain lost skills and restore independence. The advent of remote rehabilitation architecture and enabling technology mandates the elaboration of sensing mechanisms tailored to individual clinical needs. This study aims to review current trends in the application of sensing mechanisms in remote monitoring and rehabilitation in neurological diseases, and to provide clinical insights to develop bespoke sensing mechanisms. A systematic search was performed using the PubMED database to identify 16 papers published for the period between 2018 to 2022. Teleceptive sensors (56%) were utilized more often than wearable proximate sensors (50%). The most commonly used modality was infrared (38%) and acceleration force (38%), followed by RGB color, EMG, light and temperature, and radio signal. The strategy adopted to improve the sensing mechanism included a multimodal sensor, the application of multiple sensors, sensor fusion, and machine learning. Most of the stroke studies utilized biofeedback control systems (78%) while the majority of studies for neurodegenerative disorders used sensors for remote monitoring (57%). Functional assessment tools that the sensing mechanism may emulate to produce clinically valid information were proposed and factors affecting user adoption were described. Lastly, the limitations and directions for further development were discussed.

Objectives: Despite the availability of cancer rehabilitation, utilization at our institution was low. We designed the Cancer Rehabilitation Questionnaire (CRQ) to investigate the prevalence of functional impairments amongst cancer survivors and attitudes towards rehabilitation participation. We evaluated the performance of CRQ as a screening tool for detecting clinically important physical dysfunction.Design: A cross-sectional study was performed, recruiting cancer survivors at a university outpatient oncology clinic. Cancer survivors completed the CRQ and European Organization for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire – Core 30 Questionnaires. Descriptive statistical analysis and receiver operator characteristics analysis were performed to assess the ability of the CRQ to detect clinically important physical dysfunction, as measured by the EORTC QLQ-C30.Results: Of 204 participants, 87.3% reported impairments in at least 1 CRQ domain. Pain and weakness were most common. The number of positive items correlated with EORTC global health status and functional scales. A cut-off of ≥ 4 on the CRQ predicted clinically important physical dysfunction (sensitivity 61.8%, specificity 75.5%). Of those with impairments, 53.9% were unwilling to participate in rehabilitation. Transportation, need for caregivers, and cost were the main barriers.Conclusion: Our findings will guide resource allocation to overcome barriers to participation. The CRQ can help to stratify cancer survivors requiring further rehabilitation interventions. LAY ABSTRACTFunctional impairments due to cancer and its treatment are common, and can be effectively addressed with rehabilitation. To better provide cancer rehabilitation, the Cancer Rehabilitation Questionnaire was designed to investigate what functional problems cancer survivors have and their attitudes towards participation in rehabilitation. We compared the cancer rehabilitation questionnaire with the European Organization for Research and Treatment of Cancer (EORTC QLQ-C30) to see if it could be used as a screening tool for rehabilitation needs. Of 204 participants, 87.3% reported functional impairments in at least 1 Cancer Rehabilitation Questionnaire domain. Pain and weakness were most common. The number of positive Cancer Rehabilitation Questionnaire items correlated with EORTC scales: ≥ 4 positive items in the Cancer Rehabilitation Questionnaire indicated that the number of physical impairments was clinically significant. Among participants with impairments, 53.9% were unwilling to participate in rehabilitation. Transportation, need for caregivers, and cost were cited as barriers. A simple screening tool, such as the Cancer Rehabilitation Questionnaire can help to stratify cancer patients requiring further rehabilitation and intervention.
