Primary progressive multiple sclerosis (PPMS) presents with clinical signs of slowly progressive long tract dysfunction that can overlap with neurodegenerative disorders, such as hereditary spastic paraplegia (HSP). Herein, we present two siblings in whom we have identified a novel mutation in the paraplegin (SPG7) gene. The proband, a 49-year-old woman, presented with a five-year history of progressive spastic paraparesis and ataxia. Brain MRI showed mild cerebellar atrophy. The genetic study revealed a homozygous mutation in the SPG7 gene, that led to the diagnosis of HSP. Four years previously, the younger brother had complained of slowly progressive spastic-ataxic gait, that started one year before; MRI had disclosed multiple areas of white matter hyperintensity with contrast enhancement. A diagnosis of active PPMS was made, and the patient started Disease-Modifying Therapy with further clinical and radiological stability. Once a genetic diagnosis was achieved in his sister, the patient underwent SPG7 testing, which disclosed the same mutation. Whether MS is a mimicry of HSP or it represents "double trouble" condition in this patient, it remains undetermined., (Copyright © 2020 Elsevier B.V. All rights reserved.)

Background: Definition of benign multiple sclerosis (BMS) remains controversial. Moreover, a sizeable proportion of classically defined BMS patients may be no longer benign (NLB) when re-assessed in the long-term. In a previous work, we found that after a five-year follow-up, a clinical score was able to identify patients at risk of losing their benign status., Objectives: In this 12-year reappraisal of the same cohort, we aimed at assessing the predictive value of the same score in the long-term., Methods: After a mean follow-up of 12.6 + 0.4 years, patients still having an EDSS score <3.0 were classified as "still benign" (SB), whereas patients having an EDSS score ≥3.5 were defined as NLB. The predictive value of the mentioned score was re-assessed using survival analysis., Results: By the end of the follow-up, 20 (32.8%) were classified as NLB. Patients were grouped on the basis of the above mentioned score. Patients with score 2-3 were at higher risk of NLB status at the follow-up (HR = 3.5; 95%CI 1.5-8.6; p = 0.005, accuracy = 70.5%)., Conclusions: In patients with established BMS, prognostic prediction of longer-term disease course remains of critical value. In this study, a clinical score was able to predict disease evolution in the long term., (Copyright © 2018 Elsevier B.V. All rights reserved.)

Background: We report a case of a woman affected by relapsing remitting Multiple Sclerosis who developed acute left ventricular dysfunction in the context of a severe brainstem relapse, one month after an attempt of in-vitro fertilization., Discussion: The characteristics of our case are consistent with the hypothesis of a possible causal association between an acute medulla oblongata lesion and the occurrence of Takotsubo cardiomyopathy., Conclusion: Our case adds to previous reports in this field and calls for awareness of this exceptional extra-neurological manifestation of MS. It seems also to confirm the possible association between MS relapses and ovarian stimulation., (Copyright © 2018 Elsevier B.V. All rights reserved.)
