ABSTRACT
BACKGROUND: Teriflunomide (TRF) and Dimethyl fumarate (DMF) are licensed drugs for relapsing-remitting Multiple Sclerosis (RRMS). OBJECTIVES: We aimed to compare the rate and the time to discontinuation among persons with RRMS (pwRRMS), newly treated with TRF and DMF. MATERIALS AND METHODS: A retrospective study on prospectively collected data was performed in nine tertiary MS centers, in Italy. The 24-month discontinuation rate in the two cohorts was the primary study outcome. We also assessed the time to discontinuation and reasons of therapy withdrawn. Discontinuation of TRF and DMF was defined as a gap of treatment ≥ 60 days. RESULTS: A cohort of 903 pwRRMS (316 on TRF and 587 on DMF) was analyzed. During 24 months of follow-up, pwRRMS on TRF and DMF showed similar discontinuation rates. The analysis of predictors with Cox regression model showed differences between the two groups (p for log-rank test = 0.007); male gender [HR 2.21 (1.00-4.90); p = 0.01] and the number of previous switches [HR 1.47 (1.16-1.86); p = 0.01] were associated with higher hazard of discontinuation in the DMF group. CONCLUSIONS: In a real-world setting, pwRRMS on TRF and DMF had similar discontinuation rates over 24 months. Male pwRRMS on DMF with a previous history of therapeutic failure are at more risk of discontinuation therapy.

BACKGROUND AND PURPOSE: There are few population-based surveys on multiple sclerosis (MS) survival. To investigate MS survival in MS patients recruited during surveys conducted in Sicily. METHODS: Multiple sclerosis patients identified during previous surveys were randomly matched to two referent subjects by residence, year of birth, and gender. Living status was obtained by municipality records (end of follow-up June, 30th 2007) and, for the deceased, date and causes of death were searched. Kaplan-Meier plots were used to calculate differences in mortality between MS patients and referent subjects. MS risks for mortality with 95% confidence intervals (CI) were also calculated. RESULTS: We included 194 MS patients and 388 matched persons. Thirty MS patients (15.5%) and 28 referents (7.2%) had died until the end of follow-up. Mean survival from onset of the disease to death was 20.6 years. Mean age at death was 55.5 for MS patients and 64.8 for the referents. Adjusted Hazard Ratios for mortality in MS was 1.81 (95% CI 1.36-2.40). Kaplan-Meier estimates showed a higher mortality amongst patients compared to referent subjects (P < 0.001). CONCLUSIONS: The present study confirms the higher mortality risk in MS patients with no significant gender difference. Causes of death are related to complications of high disability and to increasing age.

We describe two cases of incidentally discovered split cord malformations in adults undergoing MR for symptoms unrelated to that malformation. Case 1 is an 80-year-old woman with pain due to a D7 and D8 vertebral body compression fracture resistant to medical treatment where we performed D7 and D8 percutaneous vertebroplasty with no complications and satisfactory pain control. Case 2 is a 59-year-old woman with L5 radiculopathy due to L5-S1 spondilolysthesis who had a satisfactory pain relief under medical treatment. The implementation and worldwide diffusion of MR revealed that diastematomyelia, split cord malformations traditionally seen in children, may be less rare than we thought in adults and can remain asymptomatic.
ABSTRACT
BACKGROUND AND PURPOSE: Previous studies on the association between Parkinson's disease (PD) and body mass index (BMI) have reported conflicting results. We investigated the relationship between PD and BMI by a case-control study. METHODS: PD patients were randomly matched to healthy individuals by sex and age. BMI distribution in cases has been compared with BMI of controls and odd ratios (ORs) with 95% CI were calculated. RESULTS: We included 318 PD patients and 318 controls. We observed no association between PD and BMI. BMI distribution in cases and controls was similar also when we adjusted for diabetes, hypercholesterolemia and the time elapsed between PD onset and the interview (OR = 0.99; CI = 0.94-1.03; P = 0.51). CONCLUSIONS: These results did not confirm the previously reported association between PD and BMI. Population characteristics and methodological issues may partially account for the differences observed between the present study and the others.

We present the case of a 63-year-old man with a C2 metastasis and a life expectancy of a few months who was independent at the time of diagnosis. In accordance with oncologists and radiotherapists, under antibiotic prophylaxis and general anesthesia, C2 vertebroplasty with an anterior medial transoral approach was performed, followed by radiotherapy. A satisfactory clinical result was obtained consisting in pain relief and avoidance of progression to vertebral collapse and spinal cord compression. We suggest that vertebroplasty should be performed even in compromised patients with a short life expectancy with a C2 metastasis difficult to access from a technical point of view.
ABSTRACT
In a set of a population- based study, long-term survival of 59 prevalent PD patients was compared with that of individuals free of neurological diseases matched 1:2 by sex and age of enrolment. PD individuals, compared with reference subjects, showed a two-fold increased risk of death (OR 2.1; 95 % CI 1.4, 3.1). Among causes of death, pneumonia and cachexia were significantly more frequent among PD patients than among individuals free of neurological diseases. We confirmed in a long-term follow-up study an increased mortality among PD individuals compared with that of the general population.

OBJECTIVE: To evaluate the influence of pregnancy and puerperium on the relapse rate of multiple sclerosis (MS). METHODS: We determined retrospectively the yearly mean relapse rate (MRR) during pregnancies occurring in the course of relapsing-remitting MS. We compared the MRR of pregnancy-time with that of non-pregnancy time by paired t-test. Relative risk (RR) of relapses during the pregnancy-time was also compared with that of non-pregnancy time by chi(2) analysis and 95% confidence intervals. RESULTS: From a population of 351 women affected by clinically definite MS, only 70 reported pregnancies during their relapsing-remitting phase of MS for a total of 98 pregnancies. Both MRR (P = 0.006) and RR (RR = 0.63, 95% CI = 0.40-0.94) decreased during the three trimesters of pregnancy. RR increased in the first 3 months of puerperium, although this was not statistically significant (RR = 1.36, 95% CI = 0.79-2.20). CONCLUSION: Our study confirms that in MS the relapse rate decreases throughout pregnancy and increases during puerperium. This suggests a complex interplay between hormonal and immune factors.

We report the case of a 34-year-old woman with clinical, neuroradiological and intraoperative histological findings, suggesting a low-grade astrocytic tumour. The demyelinating nature of the lesion was established through biopsy only after neurosurgery. The lesion size, in fact, greatly exceeded that of the perivenous demyelination seen in typical multiple sclerosis (MS) and tended to present as a space-occupying mass. This case underlines the importance of considering demyelinating isolated lesions in the differential diagnosis of a brain mass. Since misdiagnosis can result in unwarranted and aggressive therapy, it is critical for the neurologist to be aware of this serious diagnostic pitfall.

A young woman underwent craniotomy and wrapping of a ruptured basilar tip aneurysm on day 6 following a subarachnoid hemorrhage. An angiogram 3 years later showed that the aneurysm had disappeared. We suggest the possible reasons.
