Differentiation of Post-Polio Syndrome from Prior Poliomyelitis Sequela by Assessing Paraspinal Muscle Involvement in Magnetic Resonance Imaging.

Post-polio syndrome (PPS) affects former polio patients, manifesting decades after initial infection with progressive symptoms like pain, fatigue, and muscle weakness. Diagnosis relies on the clinical criteria and exclusion of other probable causes. The purpose of this study is to determine the scope and new diagnostic value of magnetic resonance imaging (MRI) in identifying muscle involvement in PPS and distinguishing it from prior poliomyelitis (PPM).

The frequency of superior cluneal nerve entrapment diagnosed with ultrasound-guided nerve block in patients with low back pain: A prospective, cross-sectional study.

Introduction: To determine the frequency of superior cluneal nerve entrapment (SCN-E) in patients who applied to our outpatient clinic with low back pain.

Methods: Two hundred patients with mechanical low back pain persisting more than 3 months were included in our study. All patients were evaluated with detailed clinical history and physical examination.

Quadriceps femoris muscle ultrasound in sarcoidosis: an observational case-control study.

Background: Although loss of muscle mass may be associated with general weakness, intolerance to physical activity and fatigue, it is underestimated and poorly understood in patients with sarcoidosis.

Aim: To compare the quadriceps femoris muscle (QFM) thickness measured by ultrasonography (US) between the female patients with sarcoidosis and controls, secondly to assess the correlation between the muscle strength, fatigue and QFM thickness.

Design: Observational, case-control study.

Ultrasonographic evaluation of ulnar nerve morphology in patients with ulnar nerve instability.

Introduction/aims: Ulnar nerve instability (UNI) in the retroepicondylar groove is described as nerve subluxation or dislocation. In this study, considering that instability may cause chronic ulnar nerve damage by increasing the friction risk, we aimed to examine the effects of UNI on nerve morphology ultrasonographically.

Methods: Asymptomatic patients with clinical suspicion of UNI were referred for further clinical and ultrasonographic examination.

Ultrasonographic Evaluation of Nail Involvement in Patients With Axial Spondyloarthritis.

Objectives: This study aimed to evaluate the nail units of patients with axial spondyloarthritis (ax-SpA) using ultrasound and to identify any subclinical changes. We also aimed to examine the relationship between clinical enthesitis scores and nail involvement in patients with ax-SpA.

Methods: The study included 40 patients with ax-Spa, 40 patients with psoriatic arthritis (PsA), and 40 healthy controls.
