Abstract
This study aimed to evaluate the ability of photodynamic therapy, based on the use of a gel containing 5% delta aminolaevulinic acid (ALAD) for 45' followed by irradiation with 630 nm LED (PDT) for 7', to eradicate Candida albicans strains without damaging the gingiva. C. albicans oral strains and gingival fibroblasts (hGFs) were used to achieve these goals. The potential antifungal effects on a clinical resistant C. albicans S5 strain were evaluated in terms of biofilm biomass, colony forming units (CFU/mL) count, cell viability by live/dead analysis, and fluidity membrane changes. Concerning the hGFs, viability assays, morphological analysis (optical, scanning electronic (SEM), and confocal laser scanning (CLSM) microscopes), and assays for reactive oxygen species (ROS) and collagen production were performed. ALAD-mediated aPDT (ALAD-aPDT) treatment showed significant anti-biofilm activity against C. albicans S5, as confirmed by a reduction in both the biofilm biomass and CFUs/mL. The cell viability was strongly affected by the treatment, while on the contrary, the fluidity of the membrane remained unchanged. The results for the hGFs showed an absence of cytotoxicity and no morphological differences in cells subjected to ALAD-aPDT expected for CLSM results that exhibited an increase in the thickening of actin filaments. ROS production was augmented only at 0 h and 3 h, while the collagen appeared enhanced 7 days after the treatment.

Abstract
Organs-on-a-chip (OoCs) are microfluidic devices constituted by PDMS or hydrogel in which different layers of cells are separated by a semipermeable membrane. This technology can set many parameters, like fluid shear stress, chemical concentration gradient, tissue-organ interface, and cell interaction. The use of these devices in medical research permits the investigation of cell patterning, tissue-material interface, and organ-organ interaction, mimicking the complex structures and microenvironment of human and animal bodies. This technology allows us to reconstitute in vitro complex conditions that recapitulate in vivo environments. One of the main advantages of these systems is that they represent a very realistic model that, in many cases, can replace animal experimentation, eliminating costs and related ethical issues. Organ-on-a-chip can also contain bacteria or cancer cells. This technology could be beneficial in dentistry for testing novel antibacterial substances and biomaterials, performing studies on inflammatory disease, or planning preclinical studies. A significant number of publications and reviews have been published on this topic. Still, to our knowledge, they mainly focus on the materials used for fabrication and the different patterns of the chip applied to the experimentations. This review presents the most recent applications of organ-on-a-chip models in dentistry, starting from the reconstituted dental tissues to their clinical applications and future perspectives.

Abstract
INTRODUCTION Tooth extractions can result in alveolar bone dimensional changes, necessitating additional bone grafting for implant placement. Alveolar Ridge Preservation (ARP) aims to counteract post-extraction changes. This study evaluates the bone regenerative properties of a freeze-dried bone allograft (FDBA) and the clinical outcomes of implants in grafted extraction sites. MATERIALS AND METHODS This case series enrolled 33 patients undergoing single/multiple tooth extractions followed by ARP. Biopsies were harvested during implant placement for histologic and histomorphometric analysis. Clinical outcomes included marginal bone loss and Pink Esthetic Score (PES). RESULTS 25 patients completed the study. FDBA augmented sockets exhibited new bone formation adjacent to graft particles. Implants (n=25) showed 100% survival and success rates at 1 and 2 years. PES improved significantly over time (p<.001), while marginal bone loss did not significantly differ at 1 and 2 years (p=.096). Specimens showed trabecular bone, residual FDBA particles, and marrow spaces. High magnification revealed immature bone and woven bone bridges around graft particles. No inflammatory cells were observed. CONCLUSIONS The case series provides valuable insights into ARP performed with FDBA; implants were placed after 3 months of healing without any additional bone augmentation, the histologic outcomes were favorable, and implants were successful after a 2-year period of follow-up.

Abstract
AIMS The first aim of this study was to characterize the surface topography of a novel 3D-printed dental implant at the micro- and macro-level. Its second aim was to evaluate the osteogenic, angiogenic, and immunogenic responses of human oral osteoblasts (hOBs), gingival fibroblasts (hGFs), mesenchymal stem cells (hAD-MSCs), and monocytes to this novel implant surface. METHODS A 3D-printed Ti-6Al-4 V implant was produced by selective laser melting and subjected to organic acid etching (TEST). It was then compared to a machined surface (CTRL). Its biological properties were evaluated via cell proliferation assays, morphological observations, gene expression analyses, mineralization assessments, and collagen quantifications. RESULTS Scanning electron microscopy analysis showed that the TEST group was characterized by a highly interconnected porous architecture and a roughed surface. The morphological observations showed good adhesion of cells cultured on the TEST surface, with a significant increase in hOB growth. Similarly, the gene expression analysis showed significantly higher levels of osseointegration biomarkers. Picrosirius staining showed a slight increase in collagen production in the TEST group compared to the CTRL group. hAD-MSCs showed an increase in endothelial and osteogenic commitment-related markers. Monocytes showed increased mRNA synthesis related to the M2 (anti-inflammatory) macrophagic phenotype. CONCLUSIONS Considering the higher interaction with hOBs, hGFs, hAD-MSCs, and monocytes, the prepared 3D-printed implant could be used for future clinical applications. CLINICAL RELEVANCE This study demonstrated the excellent biological response of various cells to the porous surface of the novel 3D-printed implant.

Abstract
Novel technologies such as complex magnetic fields-CMFs represent an eco-sustainable proposal to counteract the infection associated to resistant microorganisms. The aim of this study was to evaluate the effect of two CMF programs (STRESS, ANTIBACTERIAL) against clinical antifungal resistant C. albicans also evaluating their uneffectiveness on gingival fibroblasts (hGFs). The STRESS program was more efficacious on C. albicans biofilm with up to 64.37% ± 10.80 of biomass and up to 99.19% ± 0.06 CFU/ml reductions in respect to the control also inducing an alteration of lipidic structure of the membrane. The MTT assay showed no CMFs negative effects on the viability of hGFs with a major ROS production with the ANTIBACTERIAL program at 3 and 24 h. For the wound healing assay, STRESS program showed the best effect in terms of the rate migration at 24 h, showing statistical significance of p < 0.0001. The toluidine-blue staining observations showed the typical morphology of cells and the presence of elongated and spindle-shaped with cytoplasmic extensions and lamellipodia was observed by SEM. The ANTIBACTERIAL program statistically increased the production of collagen with respect to control and STRESS program (p < 0.0001). CMFs showed a relevant anti-virulence action against C. albicans, no cytotoxicity effects and a high hGFs migration rate. The results of this study suggest that CMFs could represent a novel eco-sustainable strategy to counteract the resistant yeast biofilm infections.

Abstract
BACKGROUND Although multiple sclerosis (MS) Intimacy and Sexuality Questionnaire-19 (MSISQ-19) is a widely applied tool, no unique definition of sexual dysfunction (SD) based on its score exists. OBJECTIVE To explore the impact of different MSISQ-19 cut-offs on SD prevalence and associated risk factors, providing relevant information for its application in research and clinical settings. METHODS After defining SD according to two different MSISQ-19 cut-offs in 1155 people with MS (pwMS), we evaluated SD prevalence and association with sociodemographic and clinical features, mood status and disability via logistic regression. RESULTS Depending on the chosen cut-off, 45% to 54% of pwMS reported SD. SD defined as MSISQ-19 score >30 was predicted by age (OR=1.01, p=0.047), cognition (OR=0.96, p=0.004) and anxiety (OR=1.03, p=0.019). SD defined as a score >3 on any MSISQ-19 item was predicted by motor disability (OR=1.12, p=0.003) and cognition (OR= 0.96, p=0.002). CONCLUSION Applying different MSISQ-19 cut-offs influences both the estimated prevalence and the identification of risk factors for SD, a finding that should be considered during study planning and data interpretation. Preserved cognition exerts a protective effect towards SD regardless from the specific study setting, representing a key point for the implementation of preventive and therapeutic strategies.

Abstract
This study aims to test a photodynamic protocol based on a gel containing aminolevulinic acid followed by red-LED (ALAD-PDT) irradiation on human gingival fibroblasts (hGFs) and osteoblasts (hOBs) cultured on a porcine acellular dermal matrix membrane (PADMM). In the previous literature, ALAD-PDT showed solid antibacterial activity and proliferative induction on HGFs cultured on plates and HOBs cultured on a cortical lamina. PADMMs are used in dentistry and periodontology to treat gingival recessions and to increase the tissue thickness in the case of a thin biotype without the risks or postoperative discomfort associated with connective tissue grafts. However, one of the possible complications in this type of surgery is represented by bacterial invasion and membrane exposition during the healing period. We hypothesized that the addition of ALAD-PDT to PADMMs could enhance more rapid healing and decrease the risks connected with bacterial invasion. In periodontal surgery, PADMMs are inserted after a full-thickness flap elevation between the bone and the flap. Consequently, all procedures were performed in parallel on hOBs and hGFs obtained by dental patients. The group control (CTRL) was represented by the unexposed cells cultured on the membranes, group LED (PDT) were the cells subjected to 7 min of red LED irradiation, and ALAD-PDT were the cells subjected to 45 min of ALAD incubation and then to 7 min of red LED irradiation. After treatments, all groups were analyzed for MTT assay and subjected to histological examination at 3 and 7 days and to the SEM observations at 3, 7, and 14 days. Different bone mineralization assays were performed to quantify the effects of ALAD-PDT on hOBs: ALP activity, ALP gene expression, osteocalcin, and alizarin red. The effects of ALAD-PDT on hGFs were evaluated by quantifying collagen 1, fibronectin, and MMP-8. Results showed that ALAD-PDT promoted cellular induction, forming a dense cellular network on hOBs and hGFs, and the assays performed showed statistically significantly higher values for ALAD-PDT with respect to LED alone and CTRLs. In conclusion, ALAD-PDT could represent a promising aid for enhancing the healing of gingival tissues after PADMM applications.

Abstract
The use of biomaterial for tissue repair involves the interaction between materials and cells, and the coagulum formation represents the first step of tissue healing. This process is particularly critical in the oral cavity, where the wounds are immediately subjected to the masticatory mechanical stress, saliva invasion, and bacterial attack. Therefore, the present study aimed to explore the structural features and the biological activities of a hemostatic collagen sponge on human gingival fibroblasts (HGFs) and human oral osteoblasts (HOBs). The microstructure of the collagen sponge was characterized by a scanning electron microscope (SEM) and histological analysis. The porosity was also calculated. To investigate biological activities, HGFs and HOBs were cultured on the collagen sponges, and their adhesion was observed at SEM on the third day, while cell viability was investigated at the third and seventh days by Tetrazolium (MTT) assay. For osteoblasts seeded on collagen sponge the mineralization ability was also evaluated by alkaline phosphatase (ALP) assay at the seventh day, and by Alizarin red staining on the 14th. Furthermore, the gene expression of ALP and osteocalcin (OCN) was investigated after 3, 7 and 14 days. SEM images of the sponge without cells showed a highly porous 3D structure, confirmed by the measurement of porosity that was more than 90%. The samples cultured were characterized by cells uniformly distributed and adhered to the sponge surface. Proliferation ended up being promoted, as well as the mineralization ability of the osteoblasts, mainly at the mature stage. In conclusion, this collagen sponge could have a potential use for tissue healing.

Abstract
This study aimed to evaluate the effects of a new photodynamic protocol (ALAD-PDT) on primary human osteoblasts (hOBs). The ALAD-PDT protocol consists of a heat-sensitive gel with 5% 5-delta aminolevulinic acid commercialized as Aladent (ALAD), combined with 630 nm LED. For this purpose, the hOBs, explanted from human mandible bone fragments, were used and treated with different ALAD concentrations (10%, 50%, 100% v/v) incubated for 45 min and immediately afterwards irradiated with a 630 nm LED device for 7 min. The untreated and unirradiated cells were considered control (CTRL). The cellular accumulation of the photosensitizer protoporphyrin IX (PpIX), the proliferation, the alkaline phosphatase (ALP) activity, and the calcium deposition were assessed. All concentrations (10, 50, 100%) determined a significant increment of PpIX immediately after 45 min of incubation (0 h) with the highest peak by ALAD (100%). The consequent 7 min of light irradiation caused a slight decrease in PpIX. At 48 h and 72 h, any increment of PpIX was observed. The concentration 100% associated with LED significantly increased hOB proliferation at 48 h (+ 46.83%) and 72 h (+ 127.75%). The 50% and 100% concentrations in combination to the red light also stimulated the ALP activity, + 12.910% and + 14.014% respectively. The concentration 100% with and without LED was selected for the assessment of calcium deposition. After LED irradiation, a significant increase in calcium deposition was observed and quantified (+ 72.33%). In conclusion, the ALAD-PDT enhanced proliferation, the ALP activity, and mineralized deposition of human oral osteoblasts, highlighting a promising potential for bone tissue regeneration.

Abstract
OBJECTIVE The purpose of this study is to evaluate the haemodynamic and respiratory effects of dexmedetomidine vs. propofol in patients with OSAHS during the drug-induced sleep endoscopy (DISE), and analyze simultaneously the electromyography of genioglossus muscle. PATIENTS AND METHODS We conducted a study on 50 patients with OSAHS; patients were subjected to DISE with simultaneous polygraphic cardiorespiratory measurement and electromyography of genioglossus muscle. Patients undergoing DISE were divided in two groups: in Group A (19 M; 8 W) was administered propofol TCI and in Group B (16 M; 7 W) was administered dexmedetomidine TCI. RESULTS In Group A, a mean minimal SpO2 decreasing of 3.7% (p=0.000) and a mean SpO2 decreasing of 1.6% (p 0.001) was noticed, while there was an increase in BP20 of 14.8% (p=0.000) and HR20 of 11.1% (p=0.000). In Group B, it was showed a decreasing of mean minimal SpO2 and mean SpO2 values, about 1.8% (p=0.000) and 1.1% (p 0.009) respectively, while there was an increase of BP20 and HR20, about 8.7% (p=0.000) and 8% (p 0.002), respectively. Despite EMG activity comparing spontaneous sleep with propofol-DISE, there is a statistically significative change for the amplitude (p=0.040) and an increase of 7.01% for the area under the curve (AUC). Comparing spontaneous sleep with dexmedetomidine-DISE induced one, there is only an increase of 25.87% in the AUC. CONCLUSIONS A greater worsening of the cardio-respiratory basal values was noted after sleep induction with Propofol and same results were obtained confronting EMG of genioglossus muscle data.

Abstract
BACKGROUND Teriflunomide (TRF) and Dimethyl fumarate (DMF) are licensed drugs for relapsing-remitting Multiple Sclerosis (RRMS). OBJECTIVES We aimed to compare the rate and the time to discontinuation among persons with RRMS (pwRRMS), newly treated with TRF and DMF. MATERIALS AND METHODS A retrospective study on prospectively collected data was performed in nine tertiary MS centers, in Italy. The 24-month discontinuation rate in the two cohorts was the primary study outcome. We also assessed the time to discontinuation and reasons of therapy withdrawn. Discontinuation of TRF and DMF was defined as a gap of treatment ≥ 60 days. RESULTS A cohort of 903 pwRRMS (316 on TRF and 587 on DMF) was analyzed. During 24 months of follow-up, pwRRMS on TRF and DMF showed similar discontinuation rates. The analysis of predictors with Cox regression model showed differences between the two groups (p for log-rank test = 0.007); male gender [HR 2.21 (1.00-4.90); p = 0.01] and the number of previous switches [HR 1.47 (1.16-1.86); p = 0.01] were associated with higher hazard of discontinuation in the DMF group. CONCLUSIONS In a real-world setting, pwRRMS on TRF and DMF had similar discontinuation rates over 24 months. Male pwRRMS on DMF with a previous history of therapeutic failure are at more risk of discontinuation therapy.

Abstract
BACKGROUND AND PURPOSE Late-onset multiple sclerosis (MS) has a prevalence of about 10-20% in natural history MS studies. Few data have been published about the long-term disease trajectory in the cohort of late-onset relapsing-remitting MS (LORRMS). The aim of this study was to identify the risk factors for reaching an Expanded Disability Status Scale (EDSS) score of 6.0 in LORRMS (onset at >40 years of age) and young-onset relapsing-remitting MS (YORRMS) (onset between 18 and 40 years of age). METHODS Clinical and radiological [magnetic resonance imaging (MRI) of the brain] follow-up data were collected. Disability was assessed by EDSS score. A Cox proportional hazards model was used to evaluate the demographic and clinical predictors of reaching an EDSS score of 6.0 in the two cohorts. RESULTS A total of 671 patients with relapsing-remitting MS were enrolled, 143 (21.3%) with LORRMS and 528 (78.7%) with YORRMS. In LORRMS, age at onset was 47.8 ± 5.3 (mean ± SD) years and duration of follow-up was 120.7 ± 52.7 months. In YORRMS, age at onset was 27 ± 2.7 years and duration of follow-up was 149.9 ± 92.7 months. The survival curve analyses showed a higher probability of reaching an EDSS score of 6.0 for LORRMS in a shorter time (months) than for YORRMS (94.2 vs. 103.2 months; log-rank 8.8; P < 0.05). On MRI, YORRMS showed more brain inflammatory features than LORRMS. In the multivariate Cox model, age at onset [Exp(B) value, 6.5; 95% confidence interval, 1.9-22.6; P < 0.001] and male gender [Exp(B) value, 1.7; 95% confidence interval, 1.0-2.8; P < 0.05] were the strongest predictors of reaching an EDSS score of 6.0. CONCLUSIONS The male population with LORRMS reached severe disability faster than those with YORRMS, even when YORRMS showed more brain inflammatory features on MRI.

Abstract
BACKGROUND The efficacy of lateral and escalation switch is a challenge in MS. We compared in a real-world setting the efficacy of switching to IFN beta-1a 44 mcg or to fingolimod in persons with relapsing remitting MS (pwRRMS) who failed with others injectable IFNs or glatiramer acetate. RESEARCH DESIGN AND METHODS retrospective analysis of 24 months prospectively-collected data at the MS center of the University of Catania, Italy was performed. Patients who were switched to IFN-beta 1a 44 mcg or fingolimod were analyzed using propensity-score covariate adjustment model within demographic (e.g. age and gender) and disease (e.g. timing of pre-switch relapse) characteristics. Switching-time was considered the starting-time of the observation. RESULTS 43 pwRRMS on IFN beta-1a 44 mcg and 49 pwRRMS on fingolimod were included. Baseline characteristics differed for EDSS score and number of T2 lesions (higher in group on fingolimod). At 24 months of follow up, both groups showed no differences in the survival curves of reaching a first new relapse, new T2 and Gd+ MRI brain lesions, even corrected for the propensity score covariate adjustment. CONCLUSIONS lateral switch to IFN beta-1a 44 mcg and escalation switch to fingolimod showed same ability in influencing RRMS disease activity at 24 months.

Abstract
BACKGROUND Pain is a common and heterogeneous complication of multiple sclerosis (MS). In this multicenter, cross sectional study, we aimed at investigating the prevalence of pain in MS using highly specific criteria for distinguishing the different types of pain. MATERIALS AND METHODS After a structured interview, in patients with pain, clinical examination and DN4 questionnaire were used for distinguishing neuropathic and nociceptive pain. In subjects with neuropathic pain, the Neuropathic Pain Symptom Inventory was used for differentiating neuropathic pain symptoms. RESULTS We enrolled 1249 participants (832 F, 417 M, mean age 33.9 years, mean disease duration 8 years, mean EDSS 3.2); based on clinical evaluation and DN4 score 429 patients (34.34%) were classified with pain (470 pain syndromes): 286 nociceptive pain syndromes and 184 neuropathic pain syndromes. Multivariate analysis showed that pain was associated with age, gender and disease severity and that neuropathic pain was distinctly associated with EDSS. CONCLUSIONS Our study, providing definite information on the prevalence, characteristics and variables associated with neuropathic pain due to MS, shows that a more severe disease course is associated with a higher risk of neuropathic pain. Our findings might, therefore, provide a basis for improving the clinical management of this common MS complication.

Abstract
This study Identifies the possible risk factors for osteonecrosis (ON) in a homogenous group of early system lupus erythematosus (SLE). Forty-six consecutive SLE patients (<5 years duration) followed at the Lupus Clinic, were enrolled between 2004 and 2005. An extensive clinical and laboratory evaluation using a standard electronic protocol established since 1999, including osteonecrosis symptoms and appropriate magnetic resonance imaging (MRI), were carried out at 1—6 months intervals. All other asymptomatic for osteonecrosis patients at study entry underwent MRI. ON confirmed by MRI was found in 10 of 46 patients (22%). Age, disease duration, clinical vascular features, frequency of thrombophilia and hypofibrinolysis factors and the lipoprotein profile were comparable in patients with and without osteonecrosis ( P > 0.05). Remarkably, the frequency of patients with system lupus erythematosus disease activity index (SLEDAI) ≥8 in the previous year of osteonecrosis clinical diagnosis was significantly higher when compared to patients without this manifestation (60.0% versus 19.4%, P = 0.011), supported by the higher glucocorticoid cumulative dose in the same period ( P = 0.045). In contrast, these two parameters evaluated in 13th—24th months preceding osteonecrosis diagnosis were similar in patients with and without osteonecrosis ( P > 0.05). In the logistic regression analysis only SLEDAI remained as an independent risk factor for ON (OR = 6.78, CI = 1.05—43.55, P = 0.04). Disease activity in the previous year of ON clinical diagnosis is the main predictor factor for the development of this complication in early SLE. Lupus (2007) 16, 239—244.

Abstract
BACKGROUND The presence of spinal cord (SC) magnetic resonance imaging (MRI) lesions can be expected to affect the mobility of people with relapsing-remitting MS (pwRRMS), but reports are ambiguous. OBJECTIVE The objective of this paper is to determine whether the presence of SC MRI lesions in early diagnosed pwRRMS could be considered a predictor of long-term disability. METHODS pwRRMS with an SC MRI performed within two years from the onset of symptoms and followed up for at least seven years were included. Patients were grouped into: (a) pwRRMs with at least one SC T2 MRI lesion, and (b) pwRRMs without SC T2 MRI lesions. The primary end point was to evaluate the effects of independent factors on reaching an Expanded Disability Status Score (EDSS) of 4.0. RESULTS A total of 239 pwRRMS matched the required criteria: 116 in the group with SC lesions and 123 in the group without SC lesions. At baseline, there were no statistical differences between the two groups. The presence of SC lesions (Exp(b) 4.4, CI 2.1-9.0, p < 0.001) and higher basal EDSS (Exp(b) 3.3, CI 2.3-4.8, p < 0.001) proved to be the best predictors of reaching EDSS 4.0. CONCLUSION The presence of T2 SC MRI lesions detected early from MS onset of RRMS predicts a worse prognosis.

Abstract
BACKGROUND Cyclophosphamide (Cyc) can induce ovarian failure and can have teratogenic effect. Few case reports of successful pregnancies after Cyc treatment in women with autoimmune diseases and malignancies have been described. To date, there are no data about Cyc effect on pregnancy outcomes in MS patients. AIM OF THE STUDY To describe pregnancy outcomes in multiple sclerosis (MS) patients treated with Cyc before conception. METHODS We reviewed retrospectively the medical records of all MS patients who received Cyc from 1st of January 1997 to 31st of March 2012, referring to the MS centre of the University of Catania. All pregnancies, occurred during the follow-up period after Cyc treatment, were recorded according to a computerized and standardized protocol (iMED). RESULTS We found a total of 105 MS women of childbearing age; eleven patients experienced a pregnancy (10.4%); 10 of them had a successful delivery; and one experienced a voluntary abortion. Five women had a preterm delivery. One child was small for gestational age. CONCLUSIONS Although the favourable pregnancy outcomes, Cyc should be avoided in young women planning a pregnancy. However, Cyc might be considered as a possible alternative to licensed therapies in few selected cases of very aggressive MS, including women of childbearing age.

Abstract
BACKGROUND The relationship between multiple sclerosis (MS) and headache (HA) is not well known. It was reported that interferon-beta (IFNβ) could induce or worsen HA. OBJECTIVE To evaluate the impact of IFNβ treatment on HA and the relationship between HA and the various commercial preparations of IFNβ in mildly disabled patients with MS. METHODS A specific questionnaire was administered to 357 relapsing-remitting MS patients. Characteristics of HAs were considered, including the temporal relationships with IFNβ administration. RESULTS One hundred and seventeen patients were treated with weekly intramuscular injections of interferon IFNβ-1a (Avonex(®)), 84 with subcutaneous injections of IFNβ-1b (Betaferon(®)) every other day, 48 and 108 with three times weekly subcutaneous injections of IFNβ-1a (Rebif(®)) 22 mcg or IFNβ-1a (Rebif(®)) 44 mcg, respectively. Three hundred and fourteen patients were affected by HA, and among them, 219 patients suffered of pre-existing HA. In this latter group, 121 subjects (55%) noted a worsening of their HA after starting IFNβ therapy; this was more frequently reported by patients treated with Avonex(®) and Rebif(®) 44. Ninety-five patients experienced new HA. CONCLUSION IFNβ treatment could worsen HA in patients with pre-existing HA or cause the appearance of new HA. Among different IFNβ preparations, Rebif(®) 44 and Avonex(®) seemed to be more cephalalgic than the other drugs.

Abstract
BACKGROUND The identification of biomarkers able to improve the differential diagnosis between multiple sclerosis (MS) and neuromyelitis optica (NMO) is challenging because of a different prognosis and response to treatment. Growing evidence indicates that brain and CSF N-acetyl aspartate (NAA) concentration is a useful marker for characterising different phases of axonal pathology in demyelinating diseases, and preliminary studies suggest that increased serum NAA levels may be a telltale sign of acute neuronal damage or defective NAA metabolism in oligodendrocytes. OBJECTIVE To evaluate whether serum and CSF NAA concentration differs in patients with MS and NMO. DESIGN Observational, multicentre, prospective, cross sectional study. METHODS Serum samples were collected from 48 relapsing-remitting MS, 32 NMO and 76 age matched healthy controls. Coeval CSF samples were available for all MS and for 8/32 NMO patients. NAA was measured in serum and CSF by liquid chromatography-mass spectrometry. RESULTS MS patients showed higher serum and CSF NAA levels than NMO patients, and higher serum NAA levels than healthy controls (p<0.001). High serum NAA values, exceeding the 95th percentile of serum NAA values in healthy controls, were found in 100% of patients with MS and in no patient with NMO. No differences in serum NAA levels were found between NMO and healthy controls. In MS, serum and CSF NAA levels correlated with disability score. CONCLUSIONS Determination of serum and CSF NAA levels may represent a suitable tool in the diagnostic laboratory workup to differentiate MS and NMO.

Abstract
We describe a 47-year-old male patient suffering from X-linked (or Bruton's) agammaglobulinemia with severe psoriatic arthritis (PsA), which started in childhood. PsA has been previously described in T-cell defective disorders, such as HIV infection, but our observation demonstrates that this rheumatic disease can also occur in subjects with B-lymphocyte cell functional impairment. Chronic inflammatory (bacterial?) involvement of the bowel could represent a pathogenetic connection between X-linked agammaglobulinemia and PsA.

Abstract
Swallowing problems can be relevant, even if underestimated, in Multiple Sclerosis (MS) patients. However, no specific questionnaire for the assessment of dysphagia in MS is available. We built a questionnaire (DYsphagia in MUltiple Sclerosis, DYMUS) that was administered to 226 consecutive MS patients (168 F, 58 M, mean age 40.5 years, mean disease duration 10.1 years, mean EDSS 3.1) during control visits in four Italian MS Centres. DYMUS was abnormal in 80 cases (35%). The patients who claimed to have swallowing problems had a significantly higher mean DYMUS score that the other patients (p<0.0001). Mean DYMUS scores were significantly higher in the progressive forms (p=0.003). DYMUS values were significantly correlated to EDSS (p=0.0007). DYMUS showed a very good internal consistency (Cronbach's alpha 0.877). Factor analysis allowed us to sub-divide DYMUS in two sub-scales, 'dysphagia for solid' and 'dysphagia for liquid', both of them had a very good internal consistency (Cronbach's alpha 0.852 and 0.870 respectively). DYMUS demonstrated to be an easy and consistent tool to detect dysphagia and its main characteristics in MS. It can be used for preliminary selection of patients to submit to more specific instrumental analyses, and to direct toward programs for prevention of aspiration.

Abstract
We evaluated the prevalence of hepatitis C virus (HCV) infection in Italian patients suffering from fibromyalgia (FM), in comparison with patients affected by non-HCV related rheumatic degenerative disorders. Consecutive patients with FM and a statistically comparable group of patients suffering from peripheral osteoarthritis (OA) or sciatica due to L4-L5 or L5-S1 herniated disc were tested for HCV infection with a third-generation microparticle enzyme immunoassay (MEIA). In the positive cases, a third-generation recombinant immunoblot assay (RIBA) confirmatory test and serum HCV-RNA test were performed. Fisher's exact test was performed to compare the prevalence of HCV infection (MEIA- and RIBA-positive results) obtained in the two enrolled groups. Enrolled were 152 subjects suffering from FM and 152 patients with peripheral OA or sciatica. Anti-HCV antibodies were found in 7/152 (4.6%) patients suffering from FM and in 5/152 (3.3%) of control subjects. No statistically significant differences in HCV prevalence were detected between cases and controls. Our present report does not confirm previous data indicating an increased prevalence of HCV in FM patients and does not seem to support a significant pathogenetic role of HCV under this condition.

Abstract
We describe a 28-year-old male patient in whom the development of idiopathic mixed cryoglobulinaemia (MC) with typical clinical manifestations such as polyarthralgia, weakness, purpura, and Raynaud's phenomenon was associated with a remarkable increase in serum triglycerides (TG). Prednisone administration was effective in classical cryoglobulinaemia symptoms and also in dyslipidaemia. Infective, autoimmune, and haematological disorders are often related to cryoglobulinaemia and it has been analysed that some of them also show an increase in TG.

Abstract
Hereditary angioedema (HAE) is an autosomal dominant disease that causes recurrent attacks of non-pitting edema of soft tissues, without pruritus. This disorder can also affect internal organs. The cause of HAE consists in quantitative or qualitative defective production of C1 inhibitor (C1-INH). Many autoimmune diseases such as systemic lupus erythematosus (SLE) (or SLE-like syndromes), Sjögren's syndrome, scleroderma, thyroiditis, glomerulonephritis, and inflammatory bowel disease have been described in patients suffering from HAE. A concomitance with pure arthritis was previously reported only in two adult patients. Here, we describe for the first time the association between HAE and a non-rheumatoid erosive oligoarthritis involving hips and wrists.

Abstract
Reactive oxygen and nitrogen metabolites, which are side products of cell metabolism, can produce a lot of damage in biological macromolecules and tissues, producing a number of chronic illnesses. On the other hand, antioxidant metabolites usually accumulated in fruits and vegetables can provide an effective protection by neutralizing these reactive molecules. Among comestible vegetables, berry fruits are considered one of the richest sources of antioxidant metabolites; hence, they represent a good model for molecular and biochemical investigations about the biosynthesis and the functional role of antioxidants in plants. This review illustrates how recent developments in the fields of genomics and bioinformatics can provide powerful tools to better understand the molecular mechanisms that trigger biosynthesis and accumulation of antioxidant metabolites in berries.

Abstract
The aim of this study was to review the surgical anatomy and the variants of the orbicularis oculi myocutaneus flap (OOMF) for reconstruction of inner canthus defects. Anatomic studies in fresh heads were carried out to demonstrate its blood and nerve supply. Four cases of epitheliomas of the inner canthus were treated with surgical excision and reconstructed with medially based island and nonisland OOMF. A 36-months follow-up showed no deformities of the flap, good colour matching and satisfaction scars. The flap is recommended for small to medium size defects of the inner canthus in patient with skin excess in the eyelid.

Abstract
GH excess is characterized by alterations of body composition such as decreased body fat mass; however, scant data are present regarding its effect on serum leptin levels. To better elucidate this topic, leptin secretion was studied in 20 acromegalic patients, before and after 6 months of treatment with somatostatin analogs (SR-lanreotide 30 mg and octreotide LAR). Basal GH, IGF-I, insulin, blood glucose and lipid levels were measured and the area under the curve (AUC) for insulin and glucose and oral glucose insulin sensitivity (OGIS) during oral glucose tolerance test (OGTT) were calculated. After 6 months of somatostatin analogs therapy, a significant reduction in GH and IGF-I plasma levels was observed (p<0.0005, both) with a significant increase of leptin levels (7.4+/-1.3 vs 13.2+/-1.6 ng/ml; p<0.05). Interestingly, the typical correlation of leptin with body mass index (BMI) was not present in active acromegaly, whereas it was restored after somatostatin analogs treatment; moreover, the gender difference in leptin secretion between men and women was preserved in active and controlled acromegaly. In conclusion, the gender-based leptin differences are preserved and leptin secretion/BMI ratio is normalized in acromegalic patients after somatostatin analogs therapy.

Abstract
We describe the cases of two patients with clinical and radiological findings of the reflex sympathetic dystrophy syndrome (RSDS) in whom the history of a previous genito-urinary inflammation and high levels of ESR lead us to suspect a hidden reactive arthritis. However, instrumental examinations showed a characteristic picture of RSDS without evident signs of arthritis. In both patients we decided a treatment with quinolones because of detection of an ureaplasma urealyticum genito-urinary infection. This brought to complete remission of the joint symptoms in a few days. Our findings suggest that ureaplasma urealyticum can cause and sustain a RSDS picture, maybe with a reactive arthritis-like mechanism, and that an antibiogram-driven antimicrobial treatment can be rapidly effective against this disorder.

Abstract
Reactive Arthritis (ReA) is an aseptic synovitis developing after a primary infection distant from the joint, mainly localized in the gastrointestinal (Enteroarthritis) or genitourinary tract (Uroarthritis). Because of either the asymmetric joint involvement, the possibility of involvement of the spine and enthesis, and the HLA-B27 association ReA is considered one of the spondylarthropathies. Recently, bacterial components or viable bacteria were found in joints during ReA. For this reason, the limits between ReA itself and infectious arthritis are now less definite. Generally accepted diagnostic and classification criteria are still lacking but the improvement in techniques for detection of bacteria increase the possibility to identify the triggering agents. Several studies have examined the role of antimicrobial drugs in ameliorating the natural course of ReA, with some positive results for Uroarthritis only. However, more conventional treatments based on NSAIDs, sulfasalazine and steroids are effective in many cases.

Abstract
The aim of the study was to assess the prevalence of anti-extractable nuclear antigen (ENA) antibodies in patients with chronic HCV infection. We studied 69 consecutive patients with chronic hepatitis C, 59 control subjects with non-HCV liver diseases, and 22 control subjects with extrahepatic, non-immune-mediated, chronic diseases. Thirty-two (46.3%) of 69 patients with HCV infection had anti-ENA antibodies: 16 (23.1%) showed anti-SSA antibodies and 14 (20.2%) had anti-SSB antibodies. Four of the patients with HCV infection suffered from sicca syndrome and three of them had also anti ENA antibodies. The prevalence of anti-ENA antibodies was significantly higher in the anti-HCV subjects compared with both control groups. Twenty-six of 44 HCV-antibodies-positive females had anti-ENA antibodies, compared with 6 of 25 males, showing a sex related difference. In conclusion, our results outline a specific role of HCV infection in the induction of anti-ENA antibodies. Female sex seems a predisposing condition.

Abstract
Increased monocyte adherence to the vessel wall is one of the earliest events in atherosclerosis. The mechanism by which hypercholesterolemia causes alterations in endothelial adhesiveness for monocytes is unclear. This study sought to determine if monocyte adhesion molecule expression is affected by low-density lipoprotein (LDL)-cholesterol levels. Patients with hypercholesterolemia and stable coronary artery disease were compared with those without major cardiovascular risk (control). Patients with hypercholesterolemia were treated with simvastatin 20--40 mg/day for 8--10 weeks. Blood samples were examined with flow cytometry assays at baseline and after cholesterol-lowering therapy. Monocyte CD11b and CD14 adhesion molecule expression, measured as fluorescence intensity, were significantly (P<0.0001) higher in hypercholesterolemic patients before the study (176.9+/-9.8 and 138.0+/-4.8, respectively) when compared with that in control subjects (97.2+/-8.1 and 84.0+/-6.4, respectively). Both decreased markedly with treatment: to 118.8+/-6.9 and 103.1+/-3.9, respectively. Monocyte L-selectin expression was significantly lower in patients with hypercholesterolemia before treatment (43.0+/-3.0) when compared with control subjects (79.9+/-2.7), and it increased markedly with treatment (54.2+/-2.5). LDL levels correlated directly with both CD11b and CD14 expression and correlated inversely with L-selectin expression. These data show that hypercholesterolemia affects monocyte adhesion molecule expression which, in turn, decreases with statin-induced plasmatic cholesterol reduction. Such perturbations in monocyte function likely represent a proinflammatory response to hypercholesterolemia and may have a role in the early progression of atherogenesis.

Abstract
Gastrointestinal endocrine neoplasms are rare tumours that have been classified by the peptides they secrete and the resulting clinical syndromes. The incidence of these tumours is estimated to be less than 1-1.5 cases/100,000 of the general population. These gastrointestinal endocrine cells are characterized by similar cytochemical and ultrastructural characteristics, contain amines and they are capable of uptake of amine precursors to amines or peptides. The function of these cells is the neuroendocrine regulation of normal homeostatic mechanisms including vasomotor tone as well as carbohydrate, calcium and electrolyte metabolism. Each amine precursor uptake and decarboxylation cell normally synthesizes, stores and secretes its single amine or polypeptide and is responsive to its environment for stimulation or suppression in the related clinical syndrome.
