Background There is a paucity of data concerning the optimal ventilator management in patients with COVID-19 pneumonia; particularly, the optimal levels of positive-end expiratory pressure (PEEP) are unknown. We aimed to investigate the effects of two levels of PEEP on alveolar recruitment in critically ill patients with severe COVID-19 pneumonia. Methods A single-center cohort study was conducted in a 39-bed intensive care unit at a university-affiliated hospital in Genoa, Italy. Chest computed tomography (CT) was performed to quantify aeration at 8 and 16 cmH2O PEEP. The primary endpoint was the amount of alveolar recruitment, defined as the change in the non-aerated compartment at the two PEEP levels on CT scan. Results Forty-two patients were included in this analysis. Alveolar recruitment was median [interquartile range] 2.7 [0.7–4.5] % of lung weight and was not associated with excess lung weight, PaO2/FiO2 ratio, respiratory system compliance, inflammatory and thrombophilia markers. Patients in the upper quartile of recruitment (recruiters), compared to non-recruiters, had comparable clinical characteristics, lung weight and gas volume. Alveolar recruitment was not different in patients with lower versus higher respiratory system compliance. In a subgroup of 20 patients with available gas exchange data, increasing PEEP decreased respiratory system compliance (median difference, MD − 9 ml/cmH2O, 95% CI from − 12 to − 6 ml/cmH2O, p p = 0.003), increased PaO2 with FiO2 = 0.5 (MD 24 mmHg, 95% CI from 12 to 51 mmHg, p 2 with FiO2 = 1.0 (MD 7 mmHg, 95% CI from − 12 to 49 mmHg, p = 0.313). Moreover, alveolar recruitment was not correlated with improvement of oxygenation or venous admixture. Conclusions In patients with severe COVID-19 pneumonia, higher PEEP resulted in limited alveolar recruitment. These findings suggest limiting PEEP strictly to the values necessary to maintain oxygenation, thus avoiding the use of higher PEEP levels.

This cross-sectional study has investigated the diagnostic and therapeutic management of patients suffering from multiple sclerosis (MS) in the Campania Region (Italy). A survey involving all the reference centers for MS in Campania Region was conducted from March to August 2011. Centers responded to a web-administered questionnaire on management and clinical characteristics of MS patients. In the study period, 3263 patients (mean age 37 years, 66 % females) accessed the centers. Patients received a first diagnosis of MS in 161 cases (4.9 %). About 37 % of the subjects without a previous diagnosis came to the centers on their own initiative. All patients underwent a complete neurological examination and expanded disability status scale. The other most common investigations were magnetic resonance imaging (44.0 %) and evoked potentials (22.1 %). The number of treated patients was 2797 (87.1 %). The most used drugs were interferon b and glatiramer acetate. The time between diagnosis and initiation of therapy exceeded 6 months in 32 % of cases. Second-line drugs were under-used: 16 % of patients who might benefit from them show high clinical and radiological disease activity despite treatment with immunomodulant drugs. The MS care management of the surveyed centers showed consistent margins for improvement in 2011. Even though these data do not represent the current situation, they can be used to monitor improvements in MS care.

ObjectiveTo assess the effects of subcutaneous (sc) interferon (IFN) -1a on cognition over 5 years in mildly disabled patients with relapsing-remitting multiple sclerosis (RRMS).MethodsPatients aged 18-50 years with RRMS (Expanded Disability Status Scale score ≤4.0) who had completed the 3-year COGIMUS study underwent standardized magnetic resonance imaging, neurological examination, and neuropsychological testing at years 4 and 5. Predictors of cognitive impairment at year 5 were identified using multivariate analysis.ResultsOf 331 patients who completed the 3-year COGIMUS study, 265 participated in the 2-year extension study, 201 of whom (75.8%; sc IFN β-1a three times weekly: 44 µg, n = 108; 22 µg, n = 93) completed 5 years' follow-up. The proportion of patients with cognitive impairment in the study population overall remained stable between baseline (18.0%) and year 5 (22.6%). The proportion of patients with cognitive impairment also remained stable in both treatment groups between baseline and year 5, and between year 3 and year 5. However, a significantly higher proportion of men than women had cognitive impairment at year 5 (26.5% vs 14.4%, p = 0.046). Treatment with the 22 versus 44 µg dose was predictive of cognitive impairment at year 5 (hazard ratio 0.68; 95% confidence interval 0.48-0.97).ConclusionsThis study suggests that sc IFN β-1a dose-dependently stabilizes or delays cognitive impairment over a 5-year period in most patients with mild RRMS. Women seem to be more protected against developing cognitive impairment, which may indicate greater response to therapy or the inherently better prognosis associated with female sex in MS.

Multiple sclerosis (MS) patients are often emotionally disturbed. We investigated anger in these patients in relation to demographic, clinical, and mood characteristics.About 195 cognitively unimpaired MS patients (150 relapsing-remitting and 45 progressive) were evaluated with the State Trait Anger Expression Inventory, the Chicago Multiscale Depression Inventory, and the State Trait Anxiety Inventory. The patients' anger score distribution was compared with that of the normal Italian population. Correlation coefficients among scale scores were calculated and mean anger scores were compared across different groups of patients by analysis of variance.Of the five different aspects of anger, levels of withheld and controlled Anger were respectively higher and lower than what is expected in the normal population. Although anger was correlated with anxiety and depression, it was largely independent from these mood conditions. Mean anger severity scores were not strongly influenced by individual demographic characteristics and were not higher in more severe patients.The presence of an altered pattern of anger, unrelated to the clinical severity of MS, suggests that anger is not an emotional reaction to disease stress. An alteration of anger mechanisms might be a direct consequence of the demyelination of the connections among the amygdale, the basal ganglia and the medial prefrontal cortex.

Citrus liqueurs are typical alcoholic beverages produced in the italian Region Campania. The determination of teh alcohol percentage in the alcoholic extract of citrus peel and of obtained liqueurs by density measurements using the official methods does not lead in general to accurate results. This paper proposes a simple procedure that leads to accurate results using the official methods by measuring the density on a distillate of both the alcoholic extract of citrus peel and of the derived citrus liqyeurs previously clarified by filtration to separate the essential oils.

Dysarthria is the principal motor abnormality following vascular damage to pontine paramedian structures, owing to the involvement of corticobulbar fibres. Here we describe 2 cases of adults affected by dysarthria following transient muteness as the result of a stroke in pontomesencephalic structures. Their clinical outcome was very similar to that of young patients who have undergone surgery of the 4th ventricle. Recently the importance of pons involvement has also been underlined in these cases. This case report suggests the existence of a functional network for speech, in which the pontomesencephalon is an important station for the triggering and the efficacy of verbal production.

Background To investigate in a large cohort of patients with multiple sclerosis (MS), lesion load and atrophy evolution, and the relationship between clinical and magnetic resonance imaging (MRI) correlates of disease progression. Methods Two hundred and sixty-seven patients with MS were studied at baseline and two years later using the same MRI protocol. Abnormal white matter fraction, normal appearing white matter fraction, global white matter fraction, gray matter fraction and whole brain fraction, T2-hyperintense, and T1-hypointense lesions were measured at both time points. Results The majority of patients were clinically stable, whereas MRI-derived brain tissue fractions were significantly different after 2 years. The correlation between MRI data at baseline and their variation during the follow-up showed that lower basal gray matter atrophy was significantly related with higher progression of gray matter atrophy during follow-up. The correlation between MRI parameters and disease duration showed that gray matter atrophy rate decreased with increasing disease duration, whereas the rate of white matter atrophy had a constant pattern. Lower basal gray matter atrophy was associated with increased probability of developing gray matter atrophy at follow-up, whereas gray matter atrophy progression over 2 years and new T2 lesion load were risk factors for whole brain atrophy progression. Conclusions In MS, brain atrophy occurs even after a relatively short period of time and in patients with limited progression of disability. Short-term brain atrophy progression rates differ across tissue compartments, as gray matter atrophy results more pronounced than white matter atrophy and appears to be a early phenomenon in the MS-related disease progression.
