, JA Clin Rep., 2021.06, Background: Hyperactive dysfunction syndrome (HDS) refers to a constellation of symptoms developing from cranial nerve overactivity caused by neurovascular compression at the root entry or exit zone near the brainstem. Although the combined features of HDS are seen in the elderly, there are no reports of such cases in adolescents, to date.
Case Presentation: A 17-year-old male was diagnosed with right glossopharyngeal neuralgia and treated with microvascular decompression. He experienced new-onset right facial pain later and was diagnosed with right trigeminal neuralgia, which required prompt radiofrequency thermocoagulation of the right mandibular nerve. Follow-up in the third post-treatment year revealed the absence of symptom recurrence.
Discussion: We report the treatment of a rare case of adolescent-onset combined HDS presenting as trigeminal and glossopharyngeal neuralgia. This report highlights the possibility of combined hyperactive dysfunction syndrome in younger age groups. It is crucial to establish a diagnosis early on for prompt management..

Chiaki Yamada, Aiko Maeda, Katsuyuki Matsushita, Shoko Nakayama, Kazuhiro Shirozu, Ken Yamaura., 1kHz high-frequency spinal cord stimulation alleviates chronic refractory pain after spinal cord injury: a case report., JA Clin Rep., 2021.04, Background: Patients with spinal cord injury (SCI) frequently complain of intractable pain that is resistant to conservative treatments. Here, we report the successful application of 1kHz high-frequency spinal cord stimulation (SCS) in a patient with refractory neuropathic pain secondary to SCI.
Case presentation: A 69-year-old male diagnosed with SCI (C4 American Spinal Injury Association Impairment Scale A) presented with severe at-level bilateral upper extremity neuropathic pain. Temporary improvement in his symptoms with a nerve block implied peripheral component involvement. The patient received SCS, and though the tip of the leads could not reach the cervical vertebrae, a 1kHz frequency stimulus relieved the intractable pain.
Conclusions: SCI-related symptoms may include peripheral components, SCS may have a considerable effect on intractable pain. Even when the SCS electrode lead cannot be positioned in the target area, 1kHz high-frequency SCS may still produce positive effects..
