Abstract
OBJECTIVE Sativex® is an exclusive cannabinoid-based drug approved for the treatment of spasticity due to Multiple Sclerosis (MS). The most common side effects include dizziness, nausea, and somnolence. However, it is still under debate whether the drug could cause negative cognitive effects. The aim of our study was to investigate the effect of Sativex® on functional and psychological status in cannabis-naïve MS patients. PATIENTS AND METHODS All the study participants (i.e. 40 patients affected by MS) underwent a specific clinical and neuropsychological assessment to investigate spasticity and associated symptoms, besides the cognitive and psychiatric domains commonly impaired in MS, before and after 1 and 6 months of Sativex® administration. RESULTS After the treatment, we did not observe any significant neurobehavioral impairment in all the patients, but one. CONCLUSIONS Our findings suggest that Sativex® treatment does not significantly affect the cognitive and neurobehavioral functions. However, the study supports the relevance of an extensive neuropsychological evaluation in MS patients selected for the drug administration, in an attempt to early detect the uncommon but important neurobehavioral side effects.

Abstract
Given the increasing life expectancy observed in Western countries, there is a marked interest to know more about how aging could influence respiratory health. The aim of our study was to assess the prevalence, clinical characteristics and age of onset of allergic sensitization and clinical symptoms in a sample of atopic elders living in Campania region area (Southern Italy). Fourteen Allergy units or Centres examined a total of 462 patients. In this context 215 (46.53%) had positive skin prick tests (SPTs) to at least one allergen and were diagnosed with respiratory allergy. Parietaria represents the most common sensitizing agent in elders living in Campania region, followed by dust mites, grass pollen and Olea europaea. A relatively high percentage of atopic subjects suffered from respiratory symptoms at a fairly advanced age, namely 8.3% at 60-64 years, 10.2% at 65-70 and 5.7% at > 70 years. In conclusion, the prevalence and clinical significance of airway allergic sensitization in the elderly living in Campania region is more significant than expected in latter stages of life. Physicians should not neglect the role of atopy as a risk factor for the onset of allergic respiratory symptoms even in elderly patients.

Abstract
BACKGROUND AND PURPOSE Charcot-Marie-Tooth (CMT) disease is the most common inherited neuropathy, but therapeutic options have been limited to symptom management. Past pharmacological trials have failed, possibly due to insensitive outcome measures (OMs). The aim of the current study was to evaluate the validity and reliability of the 6-min walk test (6MWT) and StepWatch(™) Activity Monitoring (SAM) with other previously validated OMs in CMT disease. METHODS A prospective multicenter study was performed, consecutively enrolling 168 CMT patients (104 with CMT1A, 27 with CMT1B, 37 with X-linked CMT) from Italian centers specializing in CMT care. RESULTS Statistical analysis showed that the 6MWT was highly related with all previously used OMs. Some, but not all, SAM parameters were related to commonly used OMs but may provide more information about quality of life. CONCLUSIONS The current study demonstrated the validity and reliability of the 6MWT and SAM as OMs for CMT. Moreover, SAM provides data that correlate better with quality of life measures, making it useful in future rehabilitation trials.

Abstract
418 Background: Approximately 30% of patients with hepatocellular carcinoma (HCC) on the wait list for liver transplant (LT) fall off the transplant list due to progressive HCC. Stereotactic Body Radiotherapy (SBRT) has been used as a “bridge” to LT in patients who are not amenable to RFA or TACE. Methods: Baseline patient characteristics, radiotherapy details and outcomes were reviewed in HCC patients who received SBRT as a bridge to LT. Results: Between July 2004 and Dec. 2014, 601 patients with HCC were listed for LT, of which 400 (66.5%) received bridging therapy. 38 patients, at high risk for HCC progression, were unsuitable for RFA or TACE, receiving SBRT as a bridging therapy. Median SBRT dose was 36Gy in 6 fractions (range 8.5-48Gy in 1 – 6 fractions), including 1 patient who was transplanted after receiving one fraction. 25 of 38 patients (67%) had all lesions treated (median number of lesions 2 {1-8}); 13 patients received SBRT only to the dominant lesion at highest risk of growing or rupturing. At the time of SBRT, 42% had HCC within Milan criteria, and median Child Pugh score was A6 (range A5-B8). 5 patients (13%) dropped off the transplant wait list due to development of metastatic disease (4) and macrovascular invasion with progressive disease (1). Median irradiated HCC volume was 60.5cc (range 7-216cc). Median liver volume (minus HCC) was 1491cc (737-2728cc). Median mean dose to the liver minus HCC was 11.2Gy (2.8-18.6Gy) and median effective liver volume irradiated was 28% (11-66%). 1 patient was admitted 2 months post SBRT with hepatic pain - possibly attributable to SBRT and another patient developed a rib fracture 8 months post SBRT (max rib dose 43Gy in 6 fractions). No other specific SBRT toxicity was noted. The 1-, 3- and 5-year disease free survival and actuarial survival of HCC patients treated with SBRT who went on to have transplant was 93%, 79% and 79%, and 89%, 76% and 76% respectively. Including patients who dropped off the transplant list, the intent-to-treat 1-, 3 - and 5-year survival was 89%, 65% and 65%. There was no reported increase in operative morbidity at the time of transplant in patients treated with SBRT. Conclusions: SBRT can be used safely and effectively in HCC patients as a bridge to liver transplant.

Abstract
PURPOSE After thyroidectomy for thyroid cancer, patients often withdraw L-T4 for diagnostic or therapeutic purposes, showing signs and symptoms of hypothyroidism. A slighter hypothyroidism (reducing L-T4 to one-half) has been proposed to limit these inconveniences. We evaluated half-dose L-T4 protocol, in comparison to conventional L-T4 withdrawal, in terms of effectiveness and improvement of clinical and biochemical disorders. METHODS We randomized 55 thyroid cancer patients into two groups: 29 patients underwent 5 weeks of half-dose of previous L-T4 treatment (HD group); 26 patients replaced L-T4 with L-T3 for 3 weeks followed by 2 weeks of withdrawal (TW group). Clinical features (Zulewsky clinical score) and biochemical parameters (lipids, liver, and muscle enzymes) were evaluated in all patients at baseline and after 5 weeks. RESULTS Total cholesterol, creatine kinase, lactate dehydrogenase, aspartate aminotransferase, and alanine aminotransferase increased at 5 weeks in both groups, but significantly more in TW, but no difference was found by clinical score. Patients who achieved the thyroid-stimulating hormone (TSH) target value (25 µU/ml) were 92.3% in TW group and 48.3% in HD group (p < 0.001). In the HD group, only basal TSH statistically correlated with the achievement of the TSH target. Receiver operating characteristic curves indicated that a basal TSH ≥0.52 μU/ml is required to reach an adequate TSH level. CONCLUSIONS Half-dose L-T4 protocol, compared to conventional L-T4 withdrawal, is associated with less biochemical disorders but no significant clinical advantage. Therefore, the half-dose protocol reaches an adequate TSH target in 48.3% of patients and is not effective unless basal serum TSH is ≥0.52 μU/ml.

Abstract
PURPOSE This work reports the extension of a semiempirical method based on the correlation ratios to convert electronic portal imaging devices transit signals into in vivo doses for the step-and-shoot intensity-modulated radiotherapy Siemens beams. The dose reconstructed at the isocenter point Diso, compared to the planned dose, Diso,TPS, and a γ-analysis between 2-dimensional electronic portal imaging device images obtained day to day, seems to supply a practical method to verify the beam delivery reproducibility. METHOD The electronic portal imaging device images were obtained by the superposition of many segment fields, and the algorithm for the Diso reconstruction for intensity-modulated radiotherapy step and shoot was formulated using a set of simulated intensity-modulated radiotherapy beams. Moreover, the in vivo dose-dedicated software was integrated with the record and verify system of the centers. RESULTS Three radiotherapy centers applied the in vivo dose procedure at 30 clinical intensity-modulated radiotherapy treatments, each one obtained with 5 or 7 beams, and planned for patients undergoing radiotherapy for prostatic tumors. Each treatment beam was checked 5 times, obtaining 900 tests of the ratios R = Diso/Diso,TPS. The average R value was equal to 1.002 ± 0.056 (2 standard deviation), while the mean R value for each patient was well within 5%, once the causes of errors were removed. The γ-analysis of the electronic portal imaging device images, with 3% 3 mm acceptance criteria, showed 90% of the tests with Pγ < 1 ≥ 95% and γmean ≤ 0.5. The off-tolerance tests were found due to incorrect setup or presence of morphological changes. This preliminary experience shows the great utility of obtaining the in vivo dose results in quasi real time and close to the linac, where the radiotherapy staff may immediately spot possible causes of errors. The in vivo dose procedure presented here is one of the objectives of a project, for the development of practical in vivo dose procedures, financially supported by the Istituto Nazionale di Fisica Nucleare.

Abstract
BACKGROUND We have shown that mycobacterial antigens and CpG oligodeoxynucleotides downmodulate airway allergic inflammation by mechanisms dependent on T-cell activation. Here, we investigated the participation of the innate response, particularly the role of MyD88 adaptor, and Fas molecules in the effectiveness of DNA-HSP65 or CpG/culture filtrated proteins (CFP) immunotherapy. METHODS Mice sensitized and challenged with Der p 1 allergen were treated with DNA-HSP65, CpG/CFP, or with adoptively transferred cells from immunized mice. The treatment efficacy was assessed by evaluating eosinophil recruitment, antibody, and cytokine production. RESULTS In addition to downregulating the Th2 response, DNA-HSP65 and CpG/CFP promoted IL-10 and IFN-γ production. Adoptive transfer of cells from mice immunized with DNA-HSP65 or CpG/CFP to allergic recipients downmodulated the allergic response. Notably, transfer of cells from DNA-HSP65- or CpG/CFP-immunized MyD88(-/-) mice failed to reduce allergy. Additionally, for effective reduction of allergy by cells from CpG/CFP-immunized mice, Fas molecules were required. Although DNA-HSP65 or CpG/CFP immunization stimulated antigen-specific production of IFN-γ and IL-10, the effect of DNA-HSP65 was associated with IL-10 while CpG/CFP was associated with IFN-γ. Moreover, after stimulation with mycobacterial antigens plus Der p 1 allergen, cells from mite-allergic patients with asthma exhibited similar patterns of cytokine production as those found in the lung of treated mice. CONCLUSIONS This study provides new insights on the mechanisms of allergen-free immunotherapy by showing that both DNA-HSP65 and CpG/CFP downregulated house dust mite-induced allergic airway inflammation via distinct pathways that involve not only induction of mycobacterial-specific adaptive responses but also signaling via MyD88 and Fas molecules.

Abstract
BACKGROUND During pregnancy, immunological and hormonal alterations place women at increased risk for influenza-related severe illnesses including hospitalization and death. Although A(H1N1) pdm09 infection resulted in increased disease severity in pregnant women, the precise mechanisms responsible for this risk have yet to be established. OBJECTIVES The present study was aimed to investigate the role of host chemokines and cytokine profiles in A(H1N1) pdm09 infection regarding disease severity in pregnant women. STUDY DESIGN This retrospective survey examined 41 pregnant women with confirmed A(H1N1) pdm09 infection. Of them, 12 died (D), 29 survived (S), and 17 remained uninfected and served as controls (C). Antiviral response was evaluated for IFN-β expression and gene expression profiles of cytokines (TNF-α, IL-6, IL-12, TGF-β) and chemokines (IL-8, RANTES, MCP-1, IP-10), and the viral Matrix (M1) gene was quantified and normalized using the housekeeping gene product β-actin mRNA. RESULTS Higher IL-8 and TNF-α mRNA expression were found in D and S compared with C, while IL-6 showed higher expression in D. Interestingly, these results were associated with a decrease in the anti-inflammatory response of TGF-β mRNA and IFN-β. These alterations would lead to an imbalance in the immune response of those patients. CONCLUSIONS Pregnancy-related reductions in IFN-β and TGF-β expression levels and elevated levels of pro-inflammatory cytokines could explain the increased severity of infection and death of pregnant women. These findings may help improve the understanding of the high susceptibility and disease severity to influenza virus infection during pregnancy.
