Walk your talk: Real-world adherence to guidelines on the use of MRI in multiple sclerosis

(1) Although guidelines about the use of MRI sequences for Multiple Sclerosis (MS) diagnosis and follow-up are available, variability in acquisition protocols is not uncommon in everyday clinical practice. The aim of this study was to evaluate the real-world application of MS imaging guidelines in different settings to clarify the level of adherence to these guidelines. (2) Via an on-line anonymous survey, neuroradiologists (NR) were asked about MRI protocols and parameters routinely acquired when MS patients are evaluated in their center, both at diagnosis and followup. Furthermore, data about report content and personal opinions about emerging neuroimaging markers were also retrieved. (3) A total of 46 participants were included, mostly working in a hospital or university hospital (80.4%) and with more than 10 years of experience (47.9%). We found a relatively good adherence to the suggested MRI protocols regarding the use of T2-weighted sequences, although almost 10% of the participants routinely acquired 2D sequences with a slice thickness superior to 3 mm. On the other hand, a wider degree of heterogeneity was found regarding gadolinium administration, almost routinely performed at follow-up examination (87.0% of cases) in contrast with the current guidelines, as well as a low use of a standardized reporting system (17.4% of cases). (4) Although the MS community is getting closer to a standardization of MRI protocols, there is still a relatively wide heterogeneity among NR, with particular reference to contrast administration, which must be overcome to guarantee an adequate quality of patients’ care in MS

Protective effect of levodropropizine against cough induced by inhalation of nebulized distilled water in patients with obstructive lung disease.

Levodropropizine is a recently developed, peripherally active antitussive agent which is widely used in clinical practice. In order to obtain further information on the spectrum of activity of this compound in experimental clinical models, a double-blind controlled study was carried out to evaluate the potential effect of the drug against cough and bronchoconstriction induced by inhalation of an ultrasonically nebulized solution of distilled water in patients with obstructive lung disease. Twenty patients were randomly divided into two groups, which received levodropropizine (60 mg t.i.d.) or placebo respectively for 7 consecutive days. Parameters evaluated at baseline and on the last day of treatment included (i) results of respiratory function tests (FEV1, IVC, FVC, TIFF, PEF, MEF75, MEF50, MEF25) performed before the stimulation test with nebulized water; (ii) total number of coughs during a 2-hour period after the stimulation test; (iii) bronchial responsiveness, quantified by calculating the volume of nebulized water required to induce a 20% reduction of FEV1 below the basal level. At pretreatment, the tussive response was very similar in the two groups. A significant decrease in number of coughs (from 34.4 +/- 8.4 at baseline to 15.6 +/- 4.9 post-treatment, p < 0.01) was observed after administration of levodropropizine, whereas placebo treatment produced no significant effect (number of coughs: 29.6 +/- 4.9 at baseline vs 24.8 +/- 9.6 post-treatment, N. S.). Bronchial responsiveness decreased significantly (compared to baseline) in both treatment groups, without any significant difference between drug and placebo. Respiratory function tests were not significantly affected by either treatment. It is concluded that levodropropizine effectively antagonizes the cough response induced by inhalation of distilled water without affecting bronchial responsiveness in patients with chronic obstructive lung disease

Dermoid Cysts - 16-year Survey

A total of 145 patients with orbital dermoid cysts examined at the Orbital Clinic, Institute of Ophthalmology, School of Medicine, University of Naples ''Federico II'' over a period of 16 years were reviewed. The orbital cysts were classified as exophytic and endophytic, according to their site of attachment in relation to the orbital rims. This classification can explain the different natural history of these lesions. The exophytic cysts growing externally are discovered in childhood, whereas the endophytic ones are discovered later in life when they produce bone damage, with or without invasion of the adjacent structures

Effect of ipratropium bromide and/or sodium cromoglycatepretreatment on water-induced bronchoconstriction in asthma

The mechanisms underlying water-induced bronchoconstriction are still not fully understood. Cholinergic reflexes and mast cell mediator release are currently believed to play an important pathogenetic role. In order to evaluate the relative contribution of each of these mechanisms, we studied the effect of ipratropium bromide (80 μg), a muscarinic antagonist, and sodium cromoglycate (20 mg), an inhibitor of mast cell mediator release, administered alone and in combination, in the prevention of bronchospasm induced by ultrasonic mist of distilled water (UMDW). Fifteen patients with documented atopic asthma and hyperresponsiveness to distilled water were selected for this randomized, placebocontrolled, double-blind study. Airway responses to pharmachological agents and bronchial challenge were measured by change in specific airways conductance (sGaw). Sodium cromoglycate had no effect on bronchial calibre, whilst ipratropium bromide and the combination of the two drugs produced a significant bronchodilation 30, 60 and 90 min after treatments. The maximal increase in sGaw (mean %±SD) was observed at 90 min: 63±28% and 58±22% after ipratropium bromide and the combined drugs respectively. UMDW (2, 4, 8, 16 ml water) caused a -36±19%, -42±19%, -49±18%, -56±15% mean %±SD fall in sGaw after placebo. Pretreatment with sodium cromoglycate abolished the bronchoconstriction to 2 ml (fall sGaw -5±23% NS) and significantly reduced the effect of 4 (-15±22%), 8 (-21±20%) and 16 ml (-24±18%) water. Ipratropium bromide caused a weaker but significant attenuation; fall in sGaw was -15±15%, -18±19%, -30±21% and -41±27% with 2, 4, 8 and 16 ml water respectively. Treatment with both drugs prevented UMDW bronchoconstriction; a decrease in sGaw greater than 10% was observed in four subjects only. These results suggest that water-induced bronchoconstriction is determined by more than one mechanism
