A Clinical Test for Diagnosis of Humeroradial Joint Lesions in the Presence of Lateral Elbow Pain: Single-Case Design with Arthroscopic Confirmation

引用

International Journal of Clinical Medicine 2018年第3期9卷 162-174页

作者： Holly Jonely jean-michel Brismée David Lutton Department of Health Human Function & Rehabilitation Sciences The George Washington School of Medicine & Health Sciences Washington DC USA Center for Rehabilitation Research Texas Tech University Health Sciences Center Lubbock TX USA Department of Orthopaedic Surgery The George Washington School of Medicine & Health Sciences Washington DC USA

INTRODUCTION: Lateral epicondylosis is a common cause of lateral elbow pain, however, some patients fail conservative management. One reason, many pathologies have similar presentations. There are no valid and reliable clinical tests to differentiate between tendopathy and arthropathy. This single case design looks at the utilization of the humeroradial joint (HRJ) distraction test to diagnose HRJ chondropathy. CASE SUMMARY: 38-year-old male recreational athlete with persistent lateral elbow pain, impaired motion, crepitus and locking. Disability of the Arm Shoulder Hand Questionnaire (DASH): 13.33/100. DASH Sport Module, 68.75/100. Differential Diagnosis: Chondropathy of the HRJ with loose body, based on history of elbow pain and locking, non-capsular pattern of limitation of motion and a positive HRJ distraction test. Intervention: loose body manipulation improved pain free range of motion with continued remarkable HRJ distraction test;referral to orthopedic surgeon. Plain radiographs and CT demonstrated a loose body and marked cartilage thinning within the HRJ. Arthroscopic removal of the loose body and plica resection was performed. Surgical exploration confirmed Grade 3 cartilage lesions within the radial head without involvement of the extensor muscle group. Post-operative physical therapy focused on restoration of accessory joint motion and education on return to functional and recreational activity. OUTCOMES: Full range and normal joint accessory motion, DASH score and DASH Sport Module score reduced to 8.33 and 25, 12-weeks post-operative. CONCLUSION: Arthroscopic exploratory surgery is recommended for chronic lateral elbow pain resistant to conservative management;however, patients who present with pain in the absence of a positive clinical examination and radiographic findings benefit least from arthroscopic evaluation. No clinical test(s) have been validated in the literature to diagnose HRJ lesions. This report is the first to propose the use of a new c

Moyamoya Disease Associated with Hyperhomocysteinemia: A Rare Cause of Stroke in Sub-Saharan Africa

引用

World Journal of Neuroscience 2022年第1期12卷 22-28页

Introduction: Moyamoya disease (MMD) is a chronic cerebrovascular disorder characterized by progressive bilateral occlusion of the supraclinoid internal carotid artery (ICA) and its main branches, associated with the development of fine collateral networks, especially adjacent to the site of occlusion in the deep areas of the brain. MMD frequently occurs in East Asian populations, including pediatric and adult patients, and may lead to ischemic or hemorrhagic stroke, headache, epilepsy or transient ischemic attack. The majority is presumed to be of genetic origin and few cases of thrombophilia have been reported in MMD. We report a case of MMD in a young sub-Saharan African woman associated with Hyperhomocysteninemia (HHCys). Observation: A 33-year-old female was seen for aphasia, which had suddenly appeared fourteen days before, and was associated with memory impairment. She mentioned chronic headaches during the 10 previous years, of frontal seat, without migraine criteria. She had no history of hypertension, no obesity, no known dyslipidemia, and there was no family history of stroke. Neurological examination noted Wernicke’s aphasia, with discreet right central facial palsy, associated with memory impairment. The brain MRI revealed semi recent infarct in the left parietal lobe, sequelae in the left temporo-occipital and right frontal with lacunar ischemic lesions, associated with several foci of sub- cortical demyelination. MRA showed stenosis of the supraclinoid carotid arteries and their division branches. In addition, there was a stenosis of the posterior cerebral arteries, with a network of anastomosis at the level of the base of the skull. An investigation of thrombophilia showed hyperhomocysteinemia (HHCys). The diagnosis of moyamoya disease associated with hyperhomocysteinemia was mentioned. She was treated by Aspirin combined to folic acid. After a 3-year setback the patient was asymptomatic. Conclusion: MMD is a rare cause of stroke in sub-Saharan Afric

Improve Image Decoding in Lightweight Environment Using a Coroutines Based Approach

The JPEG2000 still image compression standard, while providing a remedy for the many shortcomings of its predecessor JPEG, is still slow to establish itself on the Internet. This problem is mainly due to the complexity of the COder-DECoder (CODEC) which implies its non-adoption by large firms and platforms in the field of image acquisition, processing and transmission. Indeed, the encoding and decoding process consumes a lot of CPU, memory and energy resources and takes a lot of computing time. The objective of this paper is to propose a model for decoding jpeg2000 on lightweight devices running on the Android mobile operating system. This implementation uses coroutines, which are a lightweight process model with reduced resource consumption costs compared to conventional AsyncTask threadsets. The model minimizes decoding time while minimizing CPU and memory usage, resulting in a fast and energetically economical decoded image. The results of integrating the coroutines from the main thread into the decoding process instead of the AsyncTask from the main thread produced better performance in terms of computation time, CPU and memory utilization. Indeed, the use of our model has led to a gain of around 23.41% in execution time, 9.8% in CPU utilization rate and 18.56% in memory utilization rate, compared to the model proposed in the literature which uses the threads.
