ABSTRACT

RATIONALE: Paraneoplastic cerebellar degeneration (PCD) is a rare neurodegenerative syndrome associated with antibodies targeting the Purkinje cells of the cerebellum. Most cases of anti-Yo-associated PCD occur in females, with <20 cases reported in males. Herein, we report a male patient with anti-Yo-associated PCD who was treated with plasma exchange and achieved a favorable outcome. PATIENT CONCERNS: A 64-year-old man presented with progressive ataxia, gait instability, and dysuria. Electroencephalography, electromyography, brain and spinal neuroimaging, and routine laboratory examinations were all normal. The anti-neuronal antibody Anti-Yo was detected in the serum but not in the cerebrospinal fluid (CSF). DIAGNOSIS: The patient was diagnosed with definite anti-Yo-associated PCD based on the clinical manifestations, anti-Yo was detected in the serum and response to treatment. INTERVENTIONS: At beginning, the patient was treated with dexamethasone (10 mg/day for 10 days). Then, plasma exchange was performed. OUTCOMES: After treated with dexamethasone, no clinical improvement was noted in this patient. In the following month, his condition deteriorated. However, after two courses of plasma exchange, neurological examination showed marked improvement in gait. After four courses of plasma exchange, the patient could walk independently, the Romberg test was negative, and anti-Yo antibodies were undetectable. At the 6-month follow-up, the patients' symptoms were relieved, and tests for anti-Yo antibodies remained negative. LESSONS SUBSECTIONS: Treatment with plasma exchange for anti-Yo-associated male PCD patients without a concomitant tumor are recommend and need more studies.

ABSTRACT

OBJECTIVE: To evaluate sleep disturbances of Chinese frontline medical workers (FMW) under the outbreak of coronavirus disease 2019 (COVID-19), and make a comparison with non-FMW. METHODS: The medical workers from multiple hospitals in Hubei Province, China, volunteered to participate in this cross-sectional study. An online questionnaire, including Pittsburgh Sleep Quality Index (PSQI), Athens Insomnia Scale (AIS) and Visual Analogue Scale (VAS), was used to evaluate sleep disturbances and mental status. Sleep disturbances were defined as PSQI>6 points or/and AIS>6 points. We compared the scores of PSQI, AIS, anxiety and depression VAS, as well as prevalence of sleep disturbances between FMW and non-FMW. RESULTS: A total of 1306 subjects (801 FMW and 505 non-FMW) were enrolled. Compared to non-FMW, FMW had significantly higher scores of PSQI (9.3 ± 3.8 vs 7.5 ± 3.7; P < 0.001; Cohen's d = 0.47), AIS (6.9 ± 4.3 vs 5.3 ± 3.8; P < 0.001; Cohen's d = 0.38), anxiety (4.9 ± 2.7 vs 4.3 ± 2.6; P < 0.001; Cohen's d = 0.22) and depression (4.1 ± 2.5 vs 3.6 ± 2.4; P = 0.001; Cohen's d = 0.21), as well as higher prevalence of sleep disturbances according to PSQI > 6 points (78.4% vs 61.0%; relative risk [RR] = 1.29; P < 0.001) and AIS > 6 points (51.7% vs 35.6%; RR = 1.45; P < 0.001). CONCLUSION: FMW have higher prevalence of sleep disturbances and worse sleep quality than non-FMW. Further interventions should be administrated for FMW, aiming to maintain their healthy condition and guarantee their professional performance in the battle against COVID-19.
