Abstract PDF: Background
We aimed to evaluate the clinical efficacy of cervical epidural block (CEB) in enhancing upper extremity (UE) muscle strength in patients with cervical disc herniation (CDH).
Methods
Ten patients with CDH underwent a single CEB session. Follow-up assessments were conducted weekly for 2 weeks through outpatient visits. Handgrip strength on the affected side (AHGS) and the interlateral difference in handgrip strength (DHGS) between the affected and unaffected sides were measured using a dynamometer before, immediately after, 1 and 2 weeks after CEB. Neck pain and radiating UE pain were assessed using a visual analog scale (VAS) at baseline and 2 weeks posttreatment.
Results
The median patient age was 46.4 years (range, 35–78 years). The affected disc levels were C5–6 in five patients, C6–7 in three, and C5–6–7 in two. The left side was affected in six patients and the right in four. The mean VAS score for neck pain decreased from 7.2 to 2.9, whereas that for radiating UE pain decreased from 6.3 to 2.8 after treatment. Both the AHGS and DHGS improved significantly compared to the baseline values at all posttreatment times. However, no significant differences were observed among the posttreatment time points. These findings remained consistent even after adjusting for age and sex.
Conclusion
CEB may offer therapeutic benefits by alleviating pain and improving UE muscle weakness in patients with CDH. However, further large-scale prospective studies are required to validate these preliminary results and determine the long-term efficacy of CEB in managing CDH.

Abstract PDF Supplementary Material: Dystonia is a movement disorder characterized by intermittent or sustained muscle contractions that lead to abnormal postures and/or repetitive movements. Although dystonia is traditionally considered a disorder of the basal ganglia, it has been observed in association with lesions at various sites of the motor and sensory pathways, including spinal cord pathologies such as syringomyelia, tumors, and demyelinating lesions. However, there has been an increasing number of focal dystonia cases due to peripheral injuries, such as soft tissue trauma, mononeuropathy, plexopathy, and radiculopathy. In this report, to the best of our knowledge, we present the first case of a patient who developed focal hand dystonia due to cervical mass hemorrhage. We review the literature and discuss possible mechanisms.

Abstract PDF

Hand injury in children was increased due to multiple environmental risks and failed attention of parents to children in rapidly developing society. By the results of this evaluation in 37 cases, it was summarized as follows. First, hand injuries in children most commonly occurs in spring, and occurs more commonly in the children at the age of high activity. The most common level of injury is zone I by microreplantation zone, and zone II by tendon injury zone. The more desirable results were obtained by full thickness skin graft and composite graft if it were possible. For the better functional results compare to adults, the methods and procedures must be constructed after more evaluation with more clinical cases. In the cases of pediatric hand injury, the most important fact is prevention of injury, with the close attention by parents, and the second is appropriate diagnosis and treatment for more functional results.
