Pictorial Essay on Ultrasound and Magnetic Resonance Imaging of Paraspinal Muscles for Myofascial Pain Syndrome.

The paraspinal muscles of the cervical, thoracic, and lumbar spine are important pain generators because muscle strains or myofascial pain syndrome caused by trigger points are common during clinical practice. Ultrasonography is the most convenient imaging tool for evaluating these muscles due to its advantages, such as providing good delineation of soft tissues, easy accessibility, and zero radiation. Additionally, ultrasound can serve as a useful guiding tool for paraspinal muscle intervention to prevent inadvertent injuries to vital axial neurovascular structures.

Solitary Calcified Nodules as the Cause of Carpal Tunnel Syndrome: Two Case Reports and Literature Reviews.

Solitary calcified nodule-related carpal tunnel syndrome (CTS) is rare and easy to be misdiagnosed owing to the high incidence of primary CTS. Release of the transverse carpal ligament without removal of the mass leads to persistence of the symptoms and subsequent complications like wasting of the thenar muscles. Here, we report two cases of solitary calcified nodule-related CTS and discuss the role of ultrasound in preventing misdiagnosis.

[Therapeutic effect of argon green laser for diabetic retinopathy].

Objective: To investigate the therapeutic effect of argon green laser for improving the visual acuity and relieving diabetic macular oedema in patients with diabetic retinopathy (DR).

Methods: In patients with preproliferative DR (PPDR) and proliferative DR (PDR), fundus fluorescein angiography (FFA) was performed to locate the area or spot where leakage occurred, followed by argon green laser photocoagulation of the identified leakage. In the 1-year-long follow-up study, both the visual acuity and changes in diabetic macular oedema were observed in both groups.
