Abstract
OBJECTIVES Oculodentodigital dysplasia (ODDD) is a rare autosomal dominant congenital malformation syndrome characterized by high penetrance and great phenotypic heterogeneity. Neurological manifestations are thought to occur in about one third of cases, but systematic studies are not available. We performed deep neurological phenotyping of 10 patients in one ODDD pedigree. METHODS Retrospective case series. We analyzed in depth the neurological phenotype of a three-generation family segregating the heterozygous c.416 T > C, p.(Ile139Thr) in GJA1. Clinical and neuroradiological features were retrospectively evaluated. Brain MRI and visual evoked potentials were performed in 8 and 6 cases, respectively. RESULTS Central nervous system manifestations occurred in 5 patients, the most common being isolated ataxia either in isolation or combined with spasticity. Furthermore, sphincteric disturbances (neurogenic bladder and fecal incontinence) were recognized as the first manifestation in most of the patients. Subclinical electrophysiological alteration of the optic pathway occurred in all the examined patients. Neuroimaging was significant for supratentorial hypomyelination pattern and hyperintense superior cerebellar peduncle in all examined patients. CONCLUSION The neurological involvement in ODDD carriers is often missed but peculiar clinical and radiological patterns can be recognized. Deep neurological phenotyping is needed to help untangle ODDD syndrome complexity and find genotype-phenotype correlations.

Abstract
BACKGROUND The patients' request for treatment with clear aligners is constantly increasing. The aligners permit to the clinicians a valid way to solve a lot of orthodontic cases but the patients' compliance and the clinicians' capabilities and knowledge of the technique is fundamental for the outcome. METHODS Seventy-two digital models of 18 consecutive patients treated with Invisalign and Smart Track aligners for 14 weeks were analyzed. The operator positioned 24 points on each model and were obtained the values of arch depth and perimeter of arch before and after the treatment. The variations of measurement were calculated with t student test. RESULTS A decrease of arch depth and perimeter was found from t0 to t1 and the most relevant difference was observed in the upper arch depth with a decrease of 1.3 mm and in the upper arch perimeter with a difference of 1.1 mm. CONCLUSIONS There was always a decrease of the values of arch depth and arch perimeter at the end of the treatment, especially in the upper arch. These changes must be considered by the clinicians to perform a better treatment to obtain the most predictable results and a patient's higher satisfaction.

Abstract
OBJECTIVE To evaluate the degree of agreement of dietary intake reported by the patient subject with the dietary intake reported by a respondent (a next-of-kin or a caregiver), collected by a validated Food Frequency Questionnaire (FFQ). METHODOLOGY 126 adults, both sexes, the average age was 65.9 years for patients and 54.4 years for respondents. They were recruited from the General Practice Clinic at the Clinical Hospital of São Paulo (AGD-FMUSP). The agreement between the responses given by patients and respondents was assessed using Spearman, weighted Kappa and Bland Altman tests. RESULTS The analysis for accuracy between responses (Spearman test) showed a moderate degree of agreement (0.31-0.39) for Energy, Total fat, Total Saturated Fatty Acids (SFA), Total Monounsaturated Fatty Acids (MUFA). Regarding food groups a moderate agreement was found for the majority of the foods (fruits (0.30), dairy products (0.50), natural juices (0.45), beans (0.48), butter/margarine (0.55), coffee (0.41) and soda (0.45), with the exception of vegetables (0.12) and rice (0.63). The ingestion differences did not exceeded the limit of the two standard deviations for the majority of the pairs (Bland Altman). A respondent subsample composed only of husband/wives (N = 36) revealed a moderate agreement concordance for most macronutrients studied (0.30 - 0.58), except polyunsaturated fats (0.25). CONCLUSION The results of this study show that, the FFQ may be used in cases where is impossible to get the answers directly from the patients.

Abstract
BACKGROUND Myeloablative and hematopoietic stem cells transplantation therapy (HSCT) often acts as side-effect to oral mucositis (OM) with no effective treatment. This randomized-controlled trial analyzed the efficacy of palifermin, administered as a dose during HSCT therapy, as primary prophylaxis on pediatric patients with acute lymphoblastic leukemia (ALL). METHODS In this study forty-six patients (9-15 years) with B-cell acute lymphoblastic leukemia (B-ALL) were analyzed. The patients underwent allogenic HSCT conditioned by myeloablative regimen. Subsequently to randomization, patients in the palifermin group were assigned to receive palifermin, 60 mg/kg, intravenously as a single dose 3 days before and after transplant conditioning regimen cycle. The patients in the Control group received only a placebo treatment. Maximum severity of OM, incidence and duration of ulcerative OM, incidence and duration of severe OM limitations were evaluated. RESULTS A statistically significant reduction in the incidence of OM up to grade 3 in the palifermin group compared to the control group was discovered. There was also a reduction, confirmed at 60 days, in the degree of severity of mucositis in the palifermin group, with an average of 1.54 grade in the palifermin group, and of 2.16 in the Control group and in the use of opioid analgesics. CONCLUSIONS This study indicates that a single dose of palifermin used as primary prophylaxis during HSTC therapy can prevent severe OM in pediatric patients with ALL and used as secondary prophylaxis can prevent the recurrence of severe OM in high-risk patients with previous mucosal injury and improves the quality of life in pediatric patients with ALL.

Abstract
AIM Retention is the phase of orthodontic treatment that attempts to hold teeth in their corrected positions after orthodontic therapy is completed. The aim of this study was to consider fiber-reinforced composites (FRC) as a possible alternative to conventional multistranded stainless steel wire for retention through SEM analysis. METHODS Two different FRC orthodontic retainers were investigated, i.e. Everstick® (Stick Tech Ltd, Turku, Finland) (type A, 24 samples), with a diameter of 0.76 mm made of glass fibers and a Young's modulus of elasticity of 28 gpa, and Ribbond® (Ribbond, Inc., Seattle, Washington, WA, USA) (type B, 24 samples), with ultra high molecular weight and with an high Young's modulus of elasticity by polyethylene fibers cold treated with plasma gas. Six groups were created: control groups A1 and B1, composed by 8 type A and 8 type B samples without impregnation and only with fluid resin before curing; groups A2 and B2, composed respectively by 8 type A and 8 type B samples impregnated with fluid resin Heliobond for 6 seconds; groups A3 and B3, composed respectively by 8 type A and 8 type B samples impregnated with fluid resin Heliobond for 6 minutes before curing. RESULTS Cross- and lengthwise SEM analysis of the sectioned samples made showed that fiber without impregnation with fluid resin, before curing, showed interwoven and straight directed cylindrical fibers. The SEM analysis denoted that the two types of fiber shows structural characteristics differing in dimension, number, diameter and orientation of FRC without a preliminary treatment through impregnation of the fibers with fluid resin. CONCLUSION An impregnation time of 6 seconds could considerably reduced voids, crazes and microcracks of the fibers, making them more resistant to the other oral and bacterial agents. A larger time of impregnation (6 minutes), with fluid resin before hardening, further enhances the morphological characteristics of the FRC.

Abstract
Neurofibromatosis type 2 (NF2) is an autosomal dominant syndrome with a prevalence of approximately 1 in 30,000. NF 2 is characterized by bilateral vestibular schwannomas, as well as meningiomas, ependymomas and gliomas. Currently, surgical resection and radiotherapy represent the mainstay of treatment, although new studies suggest a role for certain chemotherapeutic agents. Intravenous administration of Bevacizumab (Avastin, Genetech Pharmaceuticals) has been shown to be active in the treatment of vestibular schwannomas. The IV route of administration, however, carries a risk of known systemic side-effects such as bowel perforation, wound dehiscence and pulmonary embolism. In addition, the percentage of drug that reaches the tumor site may be restricted by the blood tumor barrier. This report describes the super-selective intra-arterial infusion of Bevacizumab following blood brain barrier disruption for the treatment of vestibular schwannomas in three patients with Neurofibromatosis type 2. It represents the first time such a technique has been performed for this disease. Additionally, this method of drug delivery may have important implications in the treatment of patients with vestibular schwannomas associated with Neurofibromatosis type 2.

Abstract
Pulsar systems accelerate particles to immense energies. The detailed functioning of these engines is still poorly understood, but polarization measurements of high-energy radiation may allow us to locate where the particles are accelerated. We have detected polarized gamma rays from the vicinity of the Crab pulsar using data from the spectrometer on the International Gamma-Ray Astrophysics Laboratory satellite. Our results show polarization with an electric vector aligned with the spin axis of the neutron star, demonstrating that a substantial fraction of the high-energy electrons responsible for the polarized photons are produced in a highly ordered structure close to the pulsar.

Abstract
To identify factors that may limit acceptance of HIV testing and enrolment in the programmes for the prevention of mother-to-child-transmission of HIV, we retrospectively assessed the performance of the service at St Francis Hospital, Nsambya in Kampala. Over five years, a total of 26,556 pregnant women were offered voluntary counselling and confidential HIV testing and, if HIV positive, enrolment in the programme. Acceptance of the HIV test increased in the last two years (from 72.7% in 2001-2002 to 79.9% in 2003-2004). Enrolment in the programme increased over time and was greater among older (64% in women older than 30 years and 44.8% in those aged less than 20 years) and highly educated women. HIV prevalence was associated with age and inversely associated with the level of education. The need for specific personnel for counselling, male partners' involvement and availability of antiretroviral drugs for those who needed treatment were identified as factors possibly affecting implementation.

Abstract
BACKGROUND AND AIM Macrophage inflammatory protein 3alpha (MIP-3alpha) is a recently described lymphocyte directed C-C chemokine expressed predominately at extralymphoid sites, including the intestine. The aim of this study was to determine whether colonic epithelial cells produce MIP-3alpha and whether its expression is upregulated in inflammatory bowel disease. METHODS AND RESULTS We found that interleukin 1beta and tumour necrosis factor alpha dose dependently stimulated MIP-3alpha production in Caco-2 and HT-29 intestinal epithelial cells. In cytokine treated Caco-2 and HT-29 cells, a significant increase in MIP-3alpha protein production was observed after three hours and continued for at least 24 hours. Analysis of colonic tissues by quantitative real time polymerase chain reaction and ELISA revealed significantly elevated MIP-3alpha mRNA levels (7.9-fold; p<0.05) and protein levels (8.9-fold; p<0.05) in Crohn's disease compared with controls or ulcerative colitis. MIP-3alpha immunoreactivity in normal colon and inflammatory bowel disease was principally associated with crypt and surface epithelial cells. Moreover, MIP-3alpha protein levels were elevated in primary epithelial cells isolated from patients with inflammatory bowel disease. CONCLUSIONS These findings indicate that increased enterocyte MIP-3alpha production may play an important role in lymphocyte activation and recruitment to the colonic epithelium in Crohn's disease and ulcerative colitis.

Abstract
Lidocaine and related local anaesthetics have been shown to be effective in the treatment of ulcerative colitis (UC). However, the mechanisms underlying their therapeutic effect are poorly defined. Intestinal epithelial cells play an important role in the mucosal inflammatory response that leads to tissue damage in UC via the secretion of pro-inflammatory cytokines and chemokines. The aim of this study was to evaluate the direct immunoregulatory effect of lidocaine on pro-inflammatory cytokine and chemokine secretion from intestinal epithelial cells. HT-29 and Caco-2 cell lines were used as a model system and treated with lidocaine and related drugs. The expression of IL-8, IL-1beta and the IL-1 receptor antagonist (RA) were assessed by ELISA and quantification of mRNA. In further experiments, the effect of lidocaine on the secretion of IL-8 from freshly isolated epithelial cells stimulated with TNFalpha was tested. Lidocaine, in therapeutic concentrations, inhibited the spontaneous and TNFalpha-stimulated secretion of IL-8 and IL-1beta from HT-29 and Caco-2 cell lines in a dose-dependent manner. Similarly, suppression of IL-8 secretion was noted in the freshly isolated epithelial cells. Other local anaesthetics, bupivacaine and amethocaine, had comparable effects. Lidocaine stimulated the secretion of the anti-inflammatory molecule IL-1 RA. Both the inhibitory and the stimulatory effects of lidocaine involved regulation of transcription. The results imply that the therapeutic effect of lidocaine may be mediated, at least in part, by its direct effects on epithelial cells to inhibit the secretion of proinflammatory molecules on one hand while triggering the secretion of anti-inflammatory mediators on the other.

Abstract
Spontaneous esophageal perforation (Boerhaave's syndrome) remains a difficult diagnostic and management problem with controversial recommendations regarding its treatment. The clinical manifestations of the disease are variable, and may be misleading, thus delaying accurate recognition. On the other hand, in view of the rapid onset of severe complications, particularly mediastinitis, a prompt diagnosis is essential to a better prognosis, successful operative outcome and potential survival. A case of spontaneous perforation of the thoracic esophagus penetrating the left pleural space treated within 4 hours from admission to the Emergency Room, with minimal surgical intervention is presented. Despite negative chest X-ray, a thoracic TC showed a small right sided effusion with left sided hydropneumothorax, and the definitive diagnosis was obtained by contrast study with a water soluble medium which showed the leak communicating freely with the left pleural space. The patient underwent repair by thoracic approach, the rupture was closed with a primary suture without flap reinforcement and the pleural space drained with the placement of single chest thoracostomy tube. The recovery was uneventful. The analysis of this case report and of the appropriate literature reveals that a poor prognosis is correlated with the time elapsed between the perforation and treatment. In conclusion the importance of an early aggressive surgical treatment for the Boerhaave's syndrome is emphasized, because any perforation treated more than 24 hours after the onset of symptoms, irrespective of the procedure used, is associated with a significantly higher morbility and mortality.

Abstract
This study was designed to evaluate locoregional anesthesia (double block of sciatic and femoral nerves with ENS) for ambulatory knee arthroscopic surgery. A statistical evaluation was performed in 50 adult outpatients (41 males, 9 females, ASA class 1 or 2) undergoing ambulatory knee arthroscopic procedures. Basal and intraoperative BP, HR SaO2 were recorded and the intensity of analgesia was also assessed according to the patient's subjective evaluation. Extra sedative or analgesic requirements were also recorded. There were no statistical changes in hemodynamic parameters during the perioperative period. The effectiveness of the anaesthetic block was classified as very good in 84% of patients, good in 2%, sufficient in 6% and inadequate in 8%. All patients were discharged in four hours after surgery. Our study shows that in ambulatory arthroscopic surgery, sciatic and femoral block with ENS is a valuable alternative to general anaesthesia.

Abstract
Renal function was assessed in 20 (11 female and 9 male, age 21-76 years, mean 53) renal patients with a creatinine clearance 25-145 ml/min, mean 95, to evaluate the effects of iohexol, a non-ionic low-osmolar contrast medium. Intravenous urography was performed in 16 patients and computed body tomography in 4, using a dose of iohexol ranged between 0.6-3.3 (mean 1.17) g/kg b.w. Different parameters of renal function were determined in the week preceding and 1, 3 and 5 days after the administration of iohexol. The principal renal effect of iohexol was an increase of urinary alanine aminopeptidase, gamma-glutamyltransferase, lactate dehydrogenase, alkaline phosphatase and N-acetyl-beta-D-glucosaminidase. The maximum increase of enzymuria was observed on day 1 after the administration of iohexol. In most cases enzymes returned to base-line values within 3 days. No relevant variation of renal hemodynamics (glomerular filtration rate and effective renal plasma flow) was observed after iohexol. In conclusion, iohexol can increase of urinary enzymes, but the effect is rapidly reversible and is not accompanied by a clinically significant impairment of renal hemodynamics.
