Background and purpose
No subgroups of patients with higher treatment effects have been clearly detected in multiple sclerosis (MS). The aim of the present work was to evaluate whether there are ...subgroups of relapsing−remitting MS (RRMS) patients who are more responsive to treatments.
Methods
All published randomized clinical trials in RRMS reporting a subgroup analysis of treatment effect were collected. Two main outcomes, the annualized relapse rate (ARR) and the disability progression, were studied. The treatment effect in each subgroup was reported as a relative effect (RE), defined as the treatment effect in the subgroup relative to the overall effect. A meta‐analysis was run to compare the RE between subgroups.
Results
Six trials (6693 RRMS patients) were included. Treatment effects on ARR were significantly higher in younger than in older subjects (RE = 0.83 vs. RE = 1.30, P < 0.001), in patients with than those without gadolinium activity (RE = 0.86 vs. RE = 1.15, P = 0.005) and in patients with lower than in those with higher Expanded Disability Status Scale (RE = 0.96 vs. RE = 1.23, P = 0.02), and on disability progression in younger than in older subjects (RE = 0.82 vs. RE = 1.28, P = 0.017).
Conclusions
This study formally shows that in RRMS higher treatment effects are associated with characteristics of earlier (lower age and Expanded Disability Status Scale) and more active (higher gadolinium activity) disease.

Purpose
Our aim was to determine the main risk factors related to the occurrence of permanent alopecia in childhood medulloblastoma (MB) survivors.
Methods
We retrospectively analyzed the clinical ...features of all consecutive MB survivors treated at our institute. We divided the patients into 3 groups depending on the craniospinal irradiation (CSI) dose received and defined permanent alopecia first in terms of the skin region affected (whole scalp and nape region), then on the basis of the toxicity degree (G). Any relationship between permanent alopecia and other characteristics was investigated by a univariate and multivariate analysis and Odds ratio (OR) with confidence interval (CI) was reported.
Results
We included 41 patients with a mean10-year follow-up. High dose CSI resulted as an independent factor leading to permanent hair loss in both groups: alopecia of the whole scalp (G1 p-value 0.030, G2 p-value 0.003) and of the nape region (G1 p-value 0.038, G2 p-value 0.006). The posterior cranial fossa (PCF) boost volume and dose were not significant factors at multivariate analysis neither in permanent hair loss of the whole scalp nor only in the nuchal region.
Conclusion
In pediatric patients with MB, the development of permanent alopecia seems to depend only on the CSI dose ≥ 36 Gy. Acute damage to the hair follicle is dose dependent, but in terms of late side effects, constant and homogeneous daily irradiation of a large volume may have a stronger effect than a higher but focal dose of radiotherapy.

We have evaluated the immunological response to Hepatitis B virus (HBV) booster vaccine dose in 129 adults with underlying diseases in comparison with 694 subjects at occupational risk of infection, ...who have previously completed the primary series and resulted with anti-HBs <10 mIU/mL. After booster dose, 60.5% of the patients with underlying diseases and 14.8% of the subjects at occupational risk resulted seronegative. By comparing two groups, rate of subjects with anamnestic response was higher in at occupational risk group respect to that at risk for medical conditions (OR: 5.99 95%IC, 3.81-9.41, p < .001). This difference was associated to gender (males/females: OR: 0.619 95%IC, 0.421-0.910, p = .015) and age (better response for younger people, p = .011).
•Multiple sclerosis patients have exacerbated the Covid-19 infection similarly to the general population in the Turkish MS & Covid-19 cohort.•Immunomodulatory treatments used in the treatment of ...multiple sclerosis are not related to the severity of Covid-19 infection.•High age, high EDSS, and having a progressive MS type are risk factors for severe Covid-19 infection.•Young age and low comorbidity caused an overall mild course of Covid-19 infection in the Turkish MS population.
The pandemic of the new type of corona virus infection 2019 Covid-19 also affect people with Multiple Sclerosis (pwMS). Currently, the accumulating information on the effects of the infection regarding the demographic and clinical characteristics of the disease, as well as outcomes within different DMTs¸ enable us to have better practices on the management of the Covid-19 infection in pwMS.
To investigate the incidence of coronavirus disease 2019 (Covid-19) and to reveal the relationship between the demographic-clinical and therapeutic features and the outcome of Covid-19 infection in a multi-center national cohort of pwMS.
The Turkish Neurological Society-MS Study Group in association with the Italian MuSC-19 Study Group initiated this study. A web-based electronic Case Report Form (eCRF) of Study-MuSC-19 were used to collect the data. The demographic data and MS histories of the patients were obtained from the file tracking forms of the relevant clinics.
309 MS patients with confirmed Covid-19 infection were included in this study. Two hundred nineteen (219) were females (70.9%). The mean age was 36.9, ranging from 18 to 66, 194 of them (62.8%) were under 40. The clinical phenotype was relapsing-remitting in 277 (89.6%) and progressive in 32 (10.4%). Disease duration ranged from 0.2 years to 31.4 years. The median EDSS was 1.5, ranging from 0 to 8.5. The EDSS score was<= 1 in 134 (43%) of the patients. 91.6% of the patients were on a DMT, Fingolimod was the most frequently used drug (22.0%), followed by Interferon (20.1%). The comorbidity rate is 11.7%. We were not able to detect any significant association of DMTs with Covid-19 severity.
The Turkish MS-Covid-19 cohort had confirmed that pwMS are not at risk of having a more severe COVID-19 outcome irrespective of the DMT that they are treated. In addition, due to being a younger population with less comorbidities most had a mild disease further highlight that the only associated risk factors for having a moderate to severe COVID-19 course are similar with the general population such as having comorbid conditions and being older.

It is known that anti-Ro/SSA positivity leads to higher risk of miscarriage and fetal cardiac malformations. Particularly, anti-p200 antibodies against a finer specificity of the Ro/SSA antigen, have ...been associated with congenital heart block. The aim of the study was to assess the frequency of anti-p200 among female patients with different connective tissue diseases and, among these, the relevance of anti-p200 values in patients with cutaneous diseases compared to systemic diseases. Anti-p200 were investigated in 110 anti-Ro/SSA positive female sera, sent to our laboratory between 2008 and 2014 with suspect of connective disease, by using ELISA testing. Positivity was found in 40.9 % samples, 34 of them showed a strong positivity (values ≥ 1.0, cut off = 0.7). Patients with systemic diseases were anti-p200 positive in the 45.9 % of cases while patients with cutaneous diseases were positive in the 24.0 % of cases. Positivity for anti-p200 antibodies was revealed in 24.0 % of patients with discoid lupus erythematosus; 100 % of patients with dermatomyositis; 40.0 % of patients with mixed connective tissue disease; 25.0 % of patients with rheumatoid arthritis; 100 % of patients with Sjögren’s syndrome; 33.3 % of patients with subacute cutaneous lupus erythematosus; 42.9 % of patients with systemic lupus erythematosus; 80.0 % of patients with systemic sclerosis. No significant difference in anti-p200 prevalence was found between systemic and cutaneous involvement, nevertheless, considering only positive sera, the antibody titer was higher in systemic diseases rather than in cutaneous diseases (2.6 ± 1.7 and 1.7 ± 1.9;
p
= 0.041). The authors think screenings for anti-Ro/SSA and anti-p200 antibodies should be included in the laboratory checklist for pregnancy.

Abstract Background Asthma is characterised by chronic airway inflammation, a complex cascade of events, mostly sustained by eosinophil recruitment and activation. Fractional exhaled nitric oxide ...(FeNO) is a surrogate marker of airway inflammation closely associated with bronchial eosinophilia. FeNO is used to define asthma phenotype, to assess eosinophilic inflammatory severity and to predict corticosteroid responsiveness. Objective The aim of this study was to investigate whether FeNO may be associated with some clinical and functional factors in asthmatics evaluated in a real life setting. Methods Globally 363 patients (150 males, mean age 46.3 years) with asthma were consecutively evaluated. The following parameters were assessed: history, including comorbidities, physical examination, body mass index (BMI), lung function, asthma control grade, asthma control test (ACT), and FeNO. Results FeNO values were significantly higher in patients with poorly controlled asthma ( p < 0.01), asthma symptoms ( p = 0.015), wheezing ( p < 0.001), rhinitis diagnosis, ( p = 0.049) and rhinitis symptoms ( p = 0.019), but lower in patients with GERD ( p = 0.024) and pneumonia history ( p = 0.048). FeNO values increased in patients with the lowest corticosteroid dose ( p = 0.031). FeNO values > 25 ppb were associated with poorly controlled asthma (OR 3.71), asthma signs (OR 3.5) and symptoms (OR 1.79). A FeNO value cut-off of 29.9 ppb was fairly predictive of (AUC 0.7) poorly controlled asthma. Conclusions FeNO assessment in clinical practice may be a useful tool for monitoring asthmatics as it is associated with several clinical factors, including asthma control.
