Background:
Ultrasound has been widely used in clinical settings for the assessment of different types of Arthritis as well as in their management. This Review study assessed the diagnostic value of Ultrasonography in comparison with major types of Arthritis namely Osteoarthritis (OA), Rheumatoid Arthritis (RA), Gouty Arthritis (GA), Pseudogout (Calcium Pyrophosphate Deposition Disease - CPPD), Psoriatic Arthritis (PA), Infectious Arthritis (IA) and Spondyloarthritis (SA).
Methodology:
Computerized literature search of PubMed was conducted from 1990 to present, for publications in English on diagnostic ultrasonography and major types of arthritis. A total of 206 publications were identified. Experimental and clinical studies that focused on the ultrasound features of the major types of Arthritis were accepted. A total of 52 out of the 206 publications, met our search criteria. Among these, 12 studies focused on OA, 7 on RA, 7 on GA, 5 on CPPD, 10 on PA, 4 on IA, and 7 on SA. From all the studies, some distinctive US features are reviewed for each of the major arthritis. Some of the features were unique and some overlapped.
Conclusion:
Ultrasound may demonstrate the ability to differentiate between the major types of Arthritis on a basic level when combined with history and physical examination. This can prove to be beneficial in the early diagnosis of the major types of arthritis, but with few limitations. This review literature shows that Ultrasound can be very helpful in bed side analysis of the major types of arthritis as well as in differentiating between them, because this modality besides being non-invasive is also very cheap.
We present a new, easy, convenient method for the diagnosis of digital clubbing using ultrasound. We also discovered a new parameter for the diagnosis of clubbing fingers and identification of pseudodigital clubbing, the SDUN. The increased SDUN might be taken as an early sign of digital clubbing.
Objective: To investigate the diagnostic value of ultrasound-guided percutaneous biopsy in the diagnosis of cervical lymph node lesions.Methods: From January 2017 to August 2019, ultrasound-guided percutaneous biopsy, using clinical 16G and 18G biopsy needles, were used in 190 patients with cervical lymph node lesions. After taking out the target tissue and having a pathologically confirmed diagnosis, it was possible to determine whether the material was satisfactory or not. All patients underwent ultrasound-guided biopsy for pathological diagnosis and postoperative pathology confirmed the final diagnosis.
Results:The study found that 185 patients had satisfactory materials, reaching 97.37% of the satisfaction rate. For cervical lymph node lesions, Ultrasound-guided 16G needle biopsy achieved 100% sensitivity, 96% specificity, and 98% accuracy, whereas Ultrasound-guided 18G needle biopsy achieved 100% sensitivity, 94% specificity, and 97% accuracy respectively. There was no significant difference noted between the two needle biopsies in the diagnosis of benign and malignant lesions (P>0.05); with 84% sensitivity, 93% specificity, and 87% accuracy being significantly different (P < 0.05).
Conclusion:Ultrasound-guided percutaneous biopsy is able to ensure a high accuracy of diagnosis and thereby reduce the occurrence of complications in patients with cervical lymph node lesions.
Objective:
To investigate and validate the role of the Knee-chest Decubitus position in fetal facial feature delineation by 4D Ultrasonography.
Methods:
Pregnant women were randomly divided into two groups: One group underwent knee-chest decubitus position prior to re-examination, and the second group underwent free activities like walking for 5, 15 or 30 minutes followed by a re-examination of the fetus. The acceptability of the fetal facial images following the two above mentioned activities was compared.
Results:
The Knee-chest Decubitus position was identified to be a more successful procedure for obtaining acceptable images. Additionally, it improved the fetal position and the resulting images were achieved significantly rapidly by this maneuver compared to free movement.
Conclusion:
The knee-chest decubitus position is simple, easy, safe and fast and thus of great convenience and promising for pregnant women.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
