Evaluation of retinal microvascular changes with OCT-A in Parkinson disease and essential tremor.

This study aimed to evaluate the presence and comparison of microvascular abnormalities in essential tremor (ET) and Parkinson disease (PD) using optical coherence tomography angiography (OCT-A) and to show the relationship between retinal microvascular changes and disease stage in the patient group. A total of 176 eyes, including 26 PD diagnosed according to the United Kingdom PD Society Brain Bank criteria, 31 ET diagnosed according to the Washington heights-inwood genetic study of ET (WHIGET) criteria and 31 healthy controls, were included in the study. Unified PD assessment scale (UPDRS) motor scores, non-motor symptom scale (NMS), modified Hoehn&Yahr stages (mH&Y) and Fahn-Toloso-Marin grading scale were recorded.

Evaluation of magnetic resonance imaging findings in adhesive capsulitis: which quantitative findings are most valuable?

Objective: This study aims to investigate magnetic resonance imaging (MRI) findings in adhesive capsulitis (AC) and determine the most valuable MRI finding in diagnosis using easily applied quantitative methods.

Methods: Shoulder MRI was performed on 193 patients who were diagnosed with AC by clinical examination and 116 controls. Axillary pouch thickness (APT), superior and inferior glenohumeral ligament (SGHL and IGHL) thickness, coracohumeral ligament (CHL) thickness, fluid increase and soft-tissue thickness in the rotator interval (RI), and increases in the fluid and signal in the localization of biceps tendon attachment were evaluated.

Sonographic assessment of subacromial bursa distension during arm abduction: establishing a threshold value in the diagnosis of subacromial impingement syndrome.

Purpose: In this study, we aimed to establish a quantitative threshold value in the diagnosis of subacromial impingement syndrome by measuring the thickness of the subacromial bursa during abduction and adduction.

Materials And Methods: Forty-five patients with subacromial impingement syndrome and 54 healthy individuals underwent dynamic shoulder ultrasonography. The subacromial bursa, between the supraspinatus tendon margin and peribursal adipose tissue, was measured between the acromion and humeral head at its widest part.

Magnetic resonance imaging evaluation of shoulder joint in patients with early stage of ankylosing spondylitis: A case-control study.

Purpose: The goal of this prospective study was to determine the prevalence of shoulder abnormalities on magnetic resonance imaging (MRI) in patients with ankylosing spondylitis (AS) who have normal shoulder X-ray examinations and no clinical shoulder abnormalities using a case-control study.

Materials And Methods: Fifty-three patients with AS according to the SpondyloArthritis international Society (ASAS) criteria were enrolled in the study. Fifty-three patients with no AS served as control subjects.
