Study Design: Prospective observational study in a tertiary referral center. Patients treated via translabyrinthine surgical approach for sporadic AN microresection between December 2015 and 2018.

Determinants of therapy switch in multiple sclerosis treatment-naïve patients: A real-life study.

Background: With many options now available, first therapy choice is challenging in multiple sclerosis (MS) and depends mainly on neurologist and patient preferences.

Objectives: To identify prognostic factors for early switch after first therapy choice.

Methods: Newly diagnosed relapsing-remitting MS patients from 24 Italian centers were included.

Assessing association of comorbidities with treatment choice and persistence in MS: A real-life multicenter study.

Objective: To assess whether the presence of concomitant diseases at multiple sclerosis (MS) diagnosis is associated with the choice and the treatment persistence in an Italian MS cohort.

Methods: We included newly diagnosed patients (2010-2016) followed in 20 MS centers and collected demographic and clinical data. We evaluated baseline factors related to the presence of comorbidities and the association between comorbidities and the clinical course of MS and the time to the first treatment switch.

Pathophysiology, assessment and management of multiple sclerosis fatigue: an update.

Fatigue is one of the most common symptoms associated with multiple sclerosis, affecting almost 80% of patients with 55% of them reporting it as one of the worst symptoms experienced, often independently of the level of disability. Areas covered: We review the main pathophysiological hypothesis, fatigue assessment scales, and its management. Expert commentary: Fatigue pathophysiology is complex and is often influenced by other secondary but relevant factors (e.

Erythroblastaemia in natalizumab-treated patients with multiple sclerosis.

Background: Natalizumab is a monoclonal antibody that significantly reduces the occurrence of relapses in relapse-remitting multiple sclerosis (RRMS) patients. Early papers on the clinical use of natalizumab in RRMS patients reported erythroblastemia as occasional and transient.

Objectives: to determine the prevalence and absolute count of erythroblasts (nucleated red blood cells, NRBCs) in peripheral blood of RRMS patients in different treatment groups and healthy controls from the same geographic area using the same equipment for laboratory analysis.

Glatiramer acetate-induced hepatitis in a young female patient with multiple sclerosis.

We report the first Italian case of glatiramer acetate-related acute hepatotoxicity. A 25-years-old woman suffering from multiple sclerosis presented acute hepatitis after eight months of treatment. Neither infective, nor autoimmune markers were detected.

Long-term course of oxaliplatin-induced polyneuropathy: a prospective 2-year follow-up study.

This prospective study sought to identify the potential reversibility of oxaliplatin-induced peripheral neuropathy (OXAIPN) by following-up its long-term course 2 years after discontinuation of oxaliplatin (OXA)-based chemotherapy. Participants were 91 colorectal cancer patients treated with OXA-based chemotherapy. Neurological assessment, clinical Total Neuropathy Score© (TNSc©) and nerve conduction studies were performed at baseline (T0), the end of chemotherapy (T1) and 2 years (T2) after discontinuation of chemotherapy.

Correspondence between neurophysiological and clinical measurements of chemotherapy-induced peripheral neuropathy: secondary analysis of data from the CI-PeriNomS study.

Chemotherapy-induced peripheral neuropathy (CIPN) lacks standardized clinical measurement. The objective of the current secondary analysis was to examine data from the CIPN Outcomes Standardization (CI-PeriNomS) study for associations between clinical examinations and neurophysiological abnormalities. Logistic regression estimated the strength of associations of vibration, pin, and monofilament examinations with lower limb sensory and motor amplitudes.

Early predictors of oxaliplatin-induced cumulative neuropathy in colorectal cancer patients.

Objectives: Peripheral neuropathy ranks among the most common dose-limiting and disabling side-effect of oxaliplatin (OXA)-based chemotherapy. The aim of this prospective, multicentre study was to define early clinical and neurophysiological markers that may help to identify patients at risk of developing severe, treatment emergent, cumulative OXA-induced peripheral neuropathy (OXAIPN).

Methods: 200 colorectal cancer patients, scheduled to receive OXA-based chemotherapy, were prospectively followed.

Neurophysiological examination of dorsal sural nerve.

Introduction: Nerve conduction study of the dorsal sural nerve (DSN) has been reported to be a sensitive method for early detection of peripheral neuropathies. However, normal reference values are scarce and vary greatly among the different studies.

Methods: A comprehensive neurophysiological study, including nerve conduction velocity (NCV) and sensory nerve action potential (SNAP) recording, was performed in 294 healthy subjects (21-86 years) with no evidence of neuropathy.

Chemotherapy-induced peripheral neurotoxicity can be misdiagnosed by the National Cancer Institute Common Toxicity scale.

The assessment of chemotherapy-induced peripheral neurotoxicity (CIPN) is still uncertain as several of the most frequently used scales do not rely on a formal neurological evaluation and depend on patients' reports and examiners' interpretations. The aim of this study was to compare the assessment of CIPN using the National Cancer Institute Common Toxicity Criteria (NCI-CTC) scale and a formal neurological assessment scored with the Total Neuropathy Score (TNS, i.e.

Effects of manidipine and delapril in hypertensive patients with type 2 diabetes mellitus: the delapril and manidipine for nephroprotection in diabetes (DEMAND) randomized clinical trial.

To assess whether angiotensin-converting enzyme inhibitors and third-generation dihydropyridine calcium channel blockers ameliorate diabetic complications, we compared glomerular filtration rate (GFR; primary outcome), cardiovascular events, retinopathy, and neuropathy in 380 hypertensive type 2 diabetics with albuminuria <200 mg/min included in a multicenter, double-blind, placebo-controlled trial (DEMAND [Delapril and Manidipine for Nephroprotection in Diabetes]) and randomized to 3-year treatment with manidipine/delapril combination (10/30 mg/d; n=126), delapril (30 mg/d; n=127), or placebo (n=127). GFR was centrally measured by iohexol plasma clearance. Median monthly GFR decline (interquartile range [IQR]) was 0.
