Ultrasound versus magnetic resonance imaging in the evaluation of shoulder joint pathologies in a cohort of rheumatoid arthritis patients
AbstractBackgroundRheumatoid arthritis (RA) is a systemic autoimmune disease that has a great impact on different joints, may result in their destruction and loss of function. Although the shoulder is affected in a large portion of patients with RA, it does not receive much attention during the follow up of RA. The precise diagnosis of shoulder pain in RA is a clinical challenge and benefits from a reliable imaging modality to detect its exact origin.AimTo determine the diagnostic accuracy of ultrasound (US) in detecting shoulder joint pathologies in RA, considering magnetic resonance imaging (MRI) as the gold standard.Materials and MethodsThis cross ‐sectional, observational study was carried out on 30 RA patients complaining of unilateral or bilateral shoulder pain. Patients were subjected to history taking, clinical shoulder examination, plain X‐ray, US examination following a standardized protocol, and MRI. The results were correlated wi th each other.ResultsIn comparison with the MRI findings, US showed high accuracy in terms of sensitivity (Sn) and specificity (Sp) in supraspinatus tendinopathy (Sn 96.6%; Sp 93.3%), biceps tenosynovitis (Sn 87.5%; Sp 97.6%), subacromial ‐subdeltoid bursitis (Sn 72.7%; Sp 95.7%), humeral erosions (Sn 90.5%; Sp 97.3%), and acromioclavicular osteoarthritis (Sn 85.7%; Sp 95.7%). In terms of reliability, the agreement between US and MRI was almost perfect (κ = .9,P

We developed a three-dimensional (3D) printed simulator (3D-printed PCNL model) for urological trainees.Methods: 40 s year urology residents were randomly assigned into two groups, completing PCNL surgical steps on a URO Mentor™ surgical simulator (Group A) or on our new 3D-printed PC...
CONCLUSION: Data suggest different roles of opioidergic system and their antagonist in pain control and mood in PTSD. However, further investigations need to be done in order to reveal the role of endogenous opioidergic system and opioidergic antagonist system as a mediator in PTSD patients suffering from acute or chronic pain.

CONCLUSIONS: MSG administered parenterally to the higher dose to adult rats affects the immunoreactivity of S100β protein in PAG. Phenotypic changes of the studied cells may indicate reactivity of glial cells and increased expression of the studied protein whereas a decrease in their number may result from the increased protein secretion into the extracellular space or cytotoxic death of glial cells.

LUNG CANCER symptoms include difficulty breathing, headaches, and persistent chest pain. But you could also be at risk of an advanced tumour if you develop a subtle sign on your eyes. Could you be at risk of lung cancer?
Conclusion: GCT of the sellar region is difficult to diagnose on routine neuroimaging. Therefore, accurate diagnosis requires careful identification of clinical signs, magnetic resonance imaging including hypointensity on T2-weighted imaging, and analysis of combined morphological and immunohistochemical studies.

Conclusion: Intracranial hypotension should be considered part of the differential diagnosis for patients presenting with an upgaze palsy. PMID: 32494377 [PubMed]
In this study, we measured alterations in cerebrospinal fluid (CSF) spaces in the spinal canal and in the posterior cranial fossa distant from the site of benign foramen magnum tumors. Methods: Twenty-nine magnetic resonance imaging scans of patients with foramen magnum tumors (8 meningiomas and 21 C2 neurinomas) were identified for radiological morphometric analysis and compared with normal control scans. The anterior-posterior distance between the pontomedullary junction and the clivus, the spinal canal diameter, spinal cord diameter, and cord-canal ratios were measured at the C6 and T2 levels. Results: The mean ...
Conclusion: DAVFs are treatable lesions that rarely occur in the pediatric age group. They are associated with serious neurological morbidity. When suspected, they should be immediately diagnosed with magnetic resonance imaging/magnetic resonance angiography, and formal angiography. Prompt neurosurgical and neuroradiological/ endovascular opinions and intervention should be sought to provide and the best treatment strategy. PMID: 32494372 [PubMed]
Conclusion: Our findings indicated that burr hole drainage without irrigation is a good surgical modality in patients with CSDH, and preoperative MRI findings can evaluate the risk of recurrence. PMID: 32494371 [PubMed]
Conclusion: Image guidance can help reduce complications and is becoming an essential tool in performing ETV. IGS ETV technique may benefit young neurosurgeons the most and can help them overcome the learning curve with safety. PMID: 32494369 [PubMed]
