Abstract
Soft tissue sarcomas account for a small proportion of second cancers, with an estimated frequency of < 10%. The most common histologic type of soft tissue sarcomas as second cancers include mostly high-grade sarcomas, such as rhabdomyosarcoma, malignant peripheral nerve sheath tumour, fibrosarcoma, leiomyosarcoma, synovial sarcoma, alveolar soft part sarcoma and Ewing sarcoma/primitive neuroectodermal tumour (PNET). We report a case of superficial soft tissue Ewing sarcoma/PNET as a second cancer in a young patient previously treated for Hodgkin's disease (HD). To the best of our knowledge and based on a literature search, this is the first reported case of post-irradiation soft tissue Ewing sarcoma/PNET as a second cancer arising in the same area irradiated for cure of HD.

Abstract
BACKGROUND AND STUDY AIMS Covered self-expanding metal stents (SEMSs) have proven effective for managing malignant bile duct strictures and may reduce risk of tumor ingrowth. A new nitinol partially covered biliary SEMS was prospectively evaluated. PATIENTS AND METHODS 70 patients with inoperable extrahepatic biliary obstructions were enrolled in a prospective multicenter trial, and followed up to 6 months or death, whichever came first. Primary endpoint was adequate palliation defined as absence of recurrent biliary obstruction from partly covered SEMS placement to end of follow-up. RESULTS Mean age of the patients was 69 years and 52 % were men. Pancreatic carcinoma was present in 68 %. One stent was placed in 67 patients, two patients received two, and in one patient a guide wire could not traverse the stricture. In 55 % of patients the SEMS was inserted de novo and in 45 % for exchange with a plastic stent. Technical success was 97 %. At 6 months, 62 % of patients were free of obstructive symptoms; compared with baseline the mean number of symptoms per patient was significantly reduced (3.1 at baseline, 0.6 at 6 months; P < 0.0001) and total bilirubin levels dropped by 73 %. There were four cases of recurrent biliary obstruction, due to stent migration (2), tumor overgrowth (1), and sludge formation (1). Device-related complications included cholecystitis (3), right upper quadrant pain (1), and moderate pancreatitis (1). No tumor ingrowth was reported. CONCLUSIONS This new partially covered nitinol SEMS is easily inserted, and safe and effective in the palliation of biliary obstruction secondary to malignant bile duct strictures.

Abstract
BACKGROUND The association between genetic predisposition and environmental risk factors such as passive smoke in determining respiratory allergies is still uncertain; even less is known about the role played by passive smoking in influencing the success of therapy for rhinitis and allergic asthma. OBJECTIVE The purpose of this prospective, randomised study was to determine whether passive smoking influences the outcome of therapies in paediatric patients with allergic respiratory diseases. METHODS The study included 68 children (mean age 11.51 years; range: 5-17) suffering from perennial rhinitis and intermittent asthma monosensitised to Dermatophagoides. Thirty-four subjects were exposed to daily passive smoking in their families, 34 were not. The two groups have been then randomised to receive continuous treatment with cetirizine or SLIT for three years. RESULTS There were 3/34 (8.8%) dropouts in the SLIT arm and 4/34 (11.7%) in the cetirizine arm. After three years, the patients exposed to passive smoking showed higher nasal eosinophilia, a worse clinical-symptomatic and pharmacological score with a worsened bronchial reactivity and functional indices of persistent asthma, regardless of how they had been treated. Nevertheless, SLIT prevented the worsening of all the clinical parameters more than the antihistamine alone either among the children exposed to smoking or not. CONCLUSIONS Exposure to passive smoking in children suffering from respiratory allergies due to Dermatophagoides decreased the clinical response to both drug therapy and SLIT. Nonetheless, while the children submitted to drug therapy worsened or did not show any significant improvement, the ones treated with SLIT improved.

Abstract
OBJECTIVE Although endoscopic ultrasound combined with fine needle aspiration (EUS-FNA) is rapidly becoming the preferred diagnostic approach for the sampling and diagnosis of gastrointestinal and mediastinal malignancies, there are limited data as to its use in the diagnosis of lymphoproliferative disorders. Therefore, we carried out a retrospective evaluation of the performance of EUS-guided FNA combined with flow cytometry (FC) as a tool to improve overall sensitivity and specificity in the diagnosis of lymphoma. METHODS Of 1560 patients having EUS-guided FNA during the period of the study, a total of 56 patients were evaluated by cytology with FC after EUS-FNA. There was adequate material to perform FC analysis for all but one case. RESULTS EUS-FNA-FC gave a diagnosis of lymphoma in 11 cases and of reactive lymphadenopathy in 20. A specific histological type was defined by FC alone in eight cases. The remaining cases were diagnosed later by cytology and cell block sections: 13 carcinomas, nine granulomatous lymphadenopathies and one mediastinal extramedullary haematopoiesis. One case was considered only suspicious for lymphoma on cytology and FC but was not confirmed on molecular analysis and one had insufficient material for FC. CONCLUSIONS Our results show that a combination of EUS-FNA-FC is a feasible and highly accurate method, which may be used for the diagnosis and subtyping of deep-seated lymphoma, providing a significant improvement to cytomorphology alone both for diagnosis and treatment planning, as long as immunocytochemistry is available for non-lymphoma cases.

Abstract
Sublingual immunotherapy is widely recognized as a viable treatment for allergic rhinitis and asthma, but the optimal dosage is still under debate, especially with modified allergens. We assessed the clinical effects of a monomeric allergoid across 3 different maintenance doses in mite-monosensitized patients with rhinitis and intermittent asthma. Eighty-nine patients allergic to HDM were randomized to 3 maintenance doses of monomeric allergoid (Lais, Lofarma) or medications only. All the patients recorded their symptoms and rescue drug consumption in a diary card from November to February. Additionally, nasal eosinophil count, spirometry and methacholine bronchial challenge were performed at the beginning of the study and after 3 years. The symptom scores showed a clear improvement in all the three active arms versus baseline and versus the controls, irrespective of the dose. Likewise, a similar improvement versus baseline was seen for nasal inflammation and bronchial hyperreactivity. The SLIT with monomeric allergoids produces clinically significant results across a wide range of doses. The absence of significant side effects, even at high doses, is probably due to their low level of allergeni city.

Abstract
Reinke's edema is a benign disease of the human vocal fold, which mainly affects the sub-epithelial layer of the vocal fold. Microscopic observations show a strongly oedematous epithelium with loosened intercellular junctions, a disruption of the extracellular connections between mucosal epithelium and connective tissue, closely adherent to the thyroarytenoid muscle. Thickening of the basal layer of epithelium, known as Reinke's space, high deposition of fibronectin and chronic inflammatory infiltration it is also visible. We analyzed, together with the hepatocyte growth factor (HGF), the expression level of MIB-1 in samples harvested from patients affected by Reinke's edema, in order to define its biological role and consider it as a possible prognostic factor in the follow-up after surgical treatment. We observed a moderate expression of HGF in the lamina propria of the human vocal fold and in the basal membrane of the mucosal epithelium. Our finding suggests that this growth factor acts as an anti - fibrotic agent in Reinke's space and affects the fibronectin deposition in the lamina propria. MIB-1, on the contrary, showed a weak expression in the basement membrane of the mucosal epithelium and a total absence in the lamina propria deep layer, thus suggesting that only the superficial layer is actively involved in the reparatory process with a high regenerative capacity, together with a high deposition of fibronectin. The latter is necessary for the cellular connections reconstruction, after the inflammatory infiltration.

Abstract
Gallbladder carcinoma is the most common biliary tract tumor and the fifth most common gastrointestinal tract cancer. The prognosis of gallbladder carcinoma is poor and less than 5% of the patients are still alive five years postoperatively. Gallbladder specimens were obtained during surgical operations performed in eleven patients for resection of a gallbladder carcinoma, and during five autopsies (control cases selected among patients who died from for other causes, excluding those suffering from biliary or hepatic diseases). Immunohistochemical characterization and distribution of neurotrophins, with their respective receptors, were analyzed. The actual role played by these neurotrophic factors in the general regulation, vascular permeability, algic responsiveness, release of locally active substances and potential tumorigenesis in the gallbladder and biliary ducts compartment remains controversial. Our study revealed an increased immunohistochemical expression of NGF and TrKA in the epithelium and in the epithelial glands of the gallbladder carcinoma together with an evident immunoreactivity for BDNF in the same neoplastic areas. An evident immunoreactivity for NGF, TrKA and BDNF was observed in control specimens of gallbladder obtained during autopsies, whereas a weak or quite absent immunoreactivity was observed in the same specimens for NT4, TrKC and p75. On the contrary an appreciable immunoreactivity for p75 was observed in the specimens harvested from patients with gallbladder carcinoma. We also investigated the expression of some known tumor markers such as MIB-1 (anti Ki-67), CD34 and CA15-3, to identify a possible correlation between the expression of these molecular factors and the prognosis of gallbladder carcinoma. They resulted highly expressed in the stroma (CD34 and CA 15-3) and in the epithelium/epithelial glands (MIB-1) of the neoplastic areas and appeared to be almost absent in the control cases, suggesting that these markers, taken together, could be adopted as a panel of prognostic factors in the evaluation of the gallbladder carcinoma.

Abstract
BACKGROUND What makes a movement feel voluntary, and what might make it feel involuntary? Motor conversion disorders are characterized by movement symptoms without a neurologic cause. Conversion movements use normal voluntary motor pathways, but the symptoms are paradoxically experienced as involuntary, or lacking in self-agency. Self-agency is the experience that one is the cause of one's own actions. The matched comparison between the prediction of the action consequences (feed-forward signal) and actual sensory feedback is believed to give rise to self-agency and has been in part associated with the right inferior parietal cortex. Using fMRI, we assessed the correlates of self-agency during conversion tremor. METHODS We used a within-subject fMRI block design to compare brain activity during conversion tremor and during voluntary mimicked tremor in 8 patients. RESULTS The random effects group analysis showed that conversion tremor compared with voluntary tremor had right temporoparietal junction (TPJ) hypoactivity (p < 0.05 family-wise error whole brain corrected) and lower functional connectivity between the right TPJ, sensorimotor regions (sensorimotor cortices and cerebellar vermis), and limbic regions (ventral anterior cingulate and right ventral striatum). CONCLUSIONS The right TPJ has been implicated as a general comparator of internal predictions with actual events. We propose that the right TPJ hypoactivity and lower TPJ and sensorimotor cortex interactions may reflect the lack of an appropriate sensory prediction signal. The lack of a match for the proprioceptive feedback would lead to the perception that the conversion movement is not self-generated.

Abstract
The objective of this study is to evaluate women's awareness and interest in genetic testing for breast cancer risk, to identify socio-demographic factors, to analyse the reasons for wanting or not wanting to be tested and finally to determine whether breast cancer patients and healthy women have different attitudes towards genetic testing. Consecutive series of 879 women without and with breast cancer participated in a 20-item self-completing questionnaire. Among breast cancer patients, 57% answered that they would definitely or probably accept being tested, compared with 84% of women without breast cancer. At the multiple logistic regression analysis only to have a diagnosis of breast cancer conditioned significantly the interest to have genetic testing. Surprisingly, a family history of breast cancer was found to have no significant impact. The most frequently cited reason for being interested in genetic testing was 'to learn about your children's risk'. Although women's awareness about breast cancer genes is inadequate, the interest in genetic testing is substantial and higher both in healthy women and in women with breast cancer. These results provide important indications for the development of educational strategies.

Abstract
Cinzas leve de carvão tratadas pelo método hidrotérmico foram usadas como adsorvente de baixo custo para a remoção de íons metálicos e corante de solução aquosa. As isotermas de adsorção das cinzas leve tratadas foram estudadas e os resultados foram ajustados pelos modelos de Langmuir e Freundlich. A isoterma de Freundlich descreveu melhor o processo de adsorção do azul de metileno. Os dados de equilíbrio para a adsorção dos íons zinco e cádmio se ajustaram melhor á equação de Langmuir. O valor máximo de capacidade de adsorção obtido foi de 0,78 (mg g-1)(L mg)1/n para o azul de metileno, 38,1 mg g-1 para o Zn2+ e 67, 5 mg g-1 para o Cd2+. Os materiais sintetizados exibiram capacidades de adsorção muito maiores do que as das cinzas leves usadas como matéria-prima. O estudo mostrou que o material zeólitico pode efetivamente adsorver azul de metileno e íons metálicos com eficiências de remoção na faixa de 82-99%.

Abstract
BACKGROUND There is no agreement about exhaled nitric oxide (FE(NO)) and its change after haemodialysis (HD) in end-stage renal disease (ESRD) patients. To comprehensively assess NO production in the respiratory system, NO metabolites in exhaled breath condensate (EBC) needs to be measured in addition to FE(NO), taking into account the influence on these markers of airway pH, which may be regulated by ammonia (NH3+), present in large amounts in the breath of ESRD patients and removed by HD. STUDY DESIGN FE(NO) and NO metabolites (NOx, NO2-,NO3- ), pH and NH3+ in EBC were measured in 12 ESRD patients, before and after HD. Twelve healthy subjects acted as controls. RESULTS FE(NO )values of ESRD patients were similar to normals, while EBC-NOx, NO2-, NH3+ and pH were significantly higher in ESRD patients compared to normals (EBC-NOx 12.3, range 11.1-41.9 microm vs. 9.4, range 4.6-10.9 microm, P = 0.007; NO2- 4.70, range 1.17-8.22 microm vs. 0.90, range 0.72-1.17 microm, P = 0.023; NH3+ 2340, range 1325-3922 microm vs. 660, range 406-872 microm, P < 0.001; pH 7.16, range 6.82-7.44 vs. 6.60, range 6.42-6.76, P = 0.004, respectively). HD caused a mild significant decrease of FE(NO), and normalization of NH3+, NOx, NO2- and pH. A significant positive relationship between EBC-pH and EBC-NH3+ before and after HD (r(2) = 0.65, P = 0.000) was observed, explaining higher than normal EBC-pH before HD, while no relationship was found between EBC-pH and FE(NO) or NO metabolites. CONCLUSION Oxidative stress, and not EBC-pH, is the most probable cause of increased NO metabolites in ESRD patients before HD.
