Health-Related Quality of Life Evaluation Using the Short Form-36 in Patients With Human T-Lymphotropic Virus Type 1-Associated Myelopathy.

Background: Human T-lymphotropic virus type 1 (HTLV-1)-associated myelopathy (HAM) is a neuroinflammatory disease, causing various neurological symptoms, including motor, sensory, and bladder and bowel dysfunctions. This study was designed to reveal the impact of HAM and related symptoms on health-related quality of life (HRQoL). Methods: We analyzed the Short Form-36 (SF-36) and clinical data of 538 patients with HAM registered in the HAM-net, a nationwide patient registry for HAM in Japan. HRQoL was evaluated using the SF-6D (a health state utility value calculated from the SF-36) and eight SF-36 subscales. A general liner model was used to estimate the impact of major HAM-related symptoms, including gait dysfunction, sensory disturbance in the legs (pain and numbness), urinary dysfunction, and constipation, on the SF-6D and SF-36 subscale scores. Results: The mean age and disease duration were 62.0 and 16.5 years, respectively. Of the patients, 73.2% needed walking aid; 42.7 and 67.1% had leg pain and numbness, respectively; 92.1% had urinary dysfunction; and 77.9% had constipation. The mean SF-6D score was 0.565, which was significantly lower than the national average (0.674 in the 60-69 years age group; p < 0.001), exceeding the minimal important difference (0.05-0.1). All the major symptoms were significantly associated with a decrease in the SF-6D score. The SF-36 subscale scores were significantly lower than the national standard of 50 (p ≤ 0.001), except for mental health (MH). Gait dysfunction was associated with lower scores in physical functioning (PF), limitations on role functioning because of physical health, bodily pain, general health perception (GH), vitality (VT), and social functioning; however, no association was observed between gait dysfunction and limitations on role functioning because of emotional problems and MH. Meanwhile, sensory disturbance in the legs was associated with a decrease in scores in all subscales. Urinary dysfunction was associated with worse PF, GH, VT, and MH. Constipation was associated only with PF. Conclusion: HRQoL of patients with HAM was worse than that of the general population and was associated with all major symptoms. Thus, patients should be comprehensively managed to achieve better HRQoL.

Utility of transoral motion-mode ultrasonography to detect tongue fasciculation in patients with amyotrophic lateral sclerosis.

INTRODUCTION: Increasing evidence suggests the utility of the submandibular approach for ultrasonography to detect tongue fasciculation in amyotrophic lateral sclerosis (ALS). We hypothesized that transoral motion-mode ultrasonography (TOMU) would be useful to detect tongue fasciculation in patients with ALS. METHODS: Patients with sporadic ALS showing clinically definite tongue fasciculation were enrolled, and the ultrasonography findings of patients' tongues on TOMU and ultrasonography by the conventional submandibular approach were analyzed. RESULTS: Six patients with clinically definite ALS were enrolled in this study. Although small, irregular muscle movements of 5 to 10 mm in amplitude and 0.1 to 0.2 second in duration were detected in all patients by TOMU, similar muscle movements were detected in only two of the six patients by the submandibular approach. DISCUSSION: TOMU appeared to be useful for detecting tongue fasciculation in ALS patients. Further study is needed to better determine its role as a diagnostic tool for ALS.

Opalski Syndrome Treated with Intravenous Recombinant Tissue Type Plasminogen Activator-Case Report and Review of Literature.

A 65-year-old man with a history of Wallenberg syndrome caused by vertebral artery dissection at 62 years old was admitted to our hospital with nausea, vertigo, right facial dysesthesia, right hemiplegia, crossed sensory disturbance (sensory loss and numbness in the right face and left body below the neck), and right limb ataxia. Magnetic resonance imaging (MRI) performed 80 minutes after onset revealed no acute ischemic stroke lesions, but magnetic resonance angiography (MRA) demonstrated complete occlusion of the right vertebral artery. Based on these neurological and MRA findings, atypical lateral medullary infarction was suggested, and intravenous tissue plasminogen activator (IV-tPA) was started 178 minutes after onset. Right hemiplegia improved immediately after IV-tPA administration. MRI performed on hospital day 2 showed an acute ischemic lesion on the right side of the medulla oblongata, resulting in a diagnosis of Opalski syndrome. Opalski syndrome is a rare subtype of Wallenberg syndrome accompanied by hemiplegia of the side ipsilateral to the lesion, and expansion of the stroke lesion to the corticospinal tract below the pyramidal decussation is considered to cause ipsilateral hemiplegia. Based on this case and previous reports, Opalski syndrome should be considered when limb ataxia and crossed sensory deficit are observed among patients with hyperacute-onset hemiplegia, and IV t-PA therapy should be considered even in the absence of neurological findings such as dysphagia, dysarthria, and Horner's signs and radiological evidence of acute ischemic stroke.
