Texte intégralBackground Ischemic events (IEs) and intracranial hemorrhages (ICHs) are feared complications of atrial fibrillation (AF) and of antithrombotic treatment in such patients. Methods AF patients admitted to the Emergency Units of the Bologna area (Italy) with acute IE or ICH were prospectively recorded over a 6 month period. Results 178 patients (60 male; median age 85 y) presented with acute IE, antithrombotic therapy was: a) vitamin K antagonists (VKAs) in 31(17.4%), INR at admission: <2.0 in 16, 2.0-3.0 (ie.in range) 13, and > 3.0 in 2); b) aspirin (ASA) in 107 (60.1%); c) no treatment in 40 (22.5%), mainly because AF was not diagnosed. Twenty patients (8 male; median age 82) presented with acute ICH: 13 (65%) received VKAs (INR 2.0-3.0 in 11, above>3.0 in 2); whilst 6 (30%) received ASA. Most IEs (88%) and ICH (95%) occurred in patients aged >70. A modeling analysis of patients aged >70 was used to estimate annual incidence in subjects anticoagulated with VKAs in our Network of Anticoagulation Centers (NACs), or those expected to have AF but not included in NACs. The expected incidence of IE was 12.0%/year (95% CI 10.7-13.3) in non-NACs and 0.57 %/year (95% CI 0.42-0.76) in NACs (ARR: 11.4% y; RRR: 95%, p<0.0001). The incidence of ICH was 0.63%/year (95% CI 0.34-1.04) and 0.30%/year (95% CI 0.19-0.44), respectively (ARR: 0.33%/year; RRR: 52.4%/year, p= 0.04). Conclusion IEs occurred mainly in elderly patients who received ASA or no treatment. Half of anticoagulated patients with IEs had subtherapeutic INRs. Therapeutic approaches to elderly subjects with AF require an effective anticoagulant treatment strategy.

Texte intégralINTRODUCTION Few studies in Literature have investigated the anamnestic and medical features that might be associated with increased pain levels during medical abortion. The primary aim of our study is to identify the anamnestic and clinical characteristics that may represent risk factors for intense pain levels, with particular focus on women’s pre-treatment psychological distress and anxiety levels. Moreover, we evaluate the correlation between pain and gestational age. MATERIALS AND METHODS This prospective, observational, non-pharmacological, multicentric study was conducted at the Department of Obstetrics and Gynecology of Azienda USL of Bologna, and at the Department of Gynecology and Human Reproduction Physiopathology of IRCCS S. Orsola – Malpighi Hospital. We included all women who opted for medical treatment for abortion, between June 1st, 2021 and November 30th, 2021. In addition to anamnestic records and ultrasound data, women were asked to fill in the following questionnaires: GHQ-12, GAD-7, STAI-6, VAS. The potential risk factors were, therefore, selected for inclusion in the multivariate regression analysis. RESULTS On 242 women enrolled, 38.0% experienced severe pain during medical abortion. A previous history of intense dysmenorrhea appeared the strongest risk factor for pain, when evaluating the size effect of each significant predictor (OR = 6.30, 95% CI 2.66 – 14.91), followed by a GHQ-12 score > 9 (OR = 3.33, 95% CI 1.43 – 7.76). On the contrary, our analysis confirmed that a previous vaginal delivery represented a protective feature against intense pain (OR 0.26, 95% CI 0.14 – 0.50). CONCLUSIONS Our data clearly show that nulliparity, dysmenorrhea, and increased baseline anxiety levels significantly increase the likelihood of severe pain in women undergoing medical abortion. Medical abortion is a safe and effective procedure, but it is often associated with pain symptoms. The identification of women at risk for experiencing severe pain is crucial to improve women’s care.

Texte intégralPurpose: Sentinel lymph node (SLN) biopsy (SLNB) is widely accepted for staging of melanoma patients. It has been shown that clinico-pathological features such as Breslow thickness, ulceration, age and gender are better predictors of relapse and survival than SLN status alone. The aims of this study were 1) to evaluate the long-term (10-years) prognostic impact of SLNB and 2) to determine predictive factors associated with SLN metastasis, relapse, and melanoma specific mortality (MSM). Methods: This was a prospective observational study on 289 consecutive patients with primary cutaneous melanoma who underwent SLNB from January 2000 to December 2007, and followed until January 2014, at an Italian academic hospital. Results: SLN was positive in 64 patients (22.1%). The median follow-up was 116 (79–147) months. Ten-year disease free survival and melanoma specific survival were poor in patients with positive SLN (58.7% and 66.4%, respectively). Only the increasing Breslow thickness resulted independently associated to an increased risk of SLN metastasis. Cox regression analysis shown that Breslow thickness >2mm was an independent predictor of relapse, and male gender and Breslow thickness >2mm of MSM. At 10-year, SLN metastasis was not significantly associated either to relapse or to MSM. Conclusions: After the fifth year of follow-up, SLN metastasis is not an independent predictive factor of relapse and mortality that are mainly influenced by the characteristics of the primary tumor and of the patient. Patients with Breslow thickness >2mm regardless of the SLN status should be considered at high-risk for 10-year relapse and mortality.

Texte intégralL’utilizzo di antipsicotici atipici nei pazienti con grave cerebrolesione acquisita ha il suo razionale nel meccanismo d’azione di queste molecole rispetto ai neurolettici convenzionali. In questa tipologia di pazienti è necessario nella maggior parte dei casi intervenire farmacologicamente su quadri di tipo comportamentale e su aspetti cognitivi che si manifestano in seguito al danno, piuttosto che sulla produttività psicotica classica dei quadri schizofrenici. In altre parole, l’efficacia antipsicotica derivante dal blocco della via dopaminergica mesolimbica sulla sintomatologia positiva, non è la caratteristica dirimente nella scelta di un farmaco antipsicotico nel grave cerebroleso. Svolgono un ruolo di i maggiore rilevanza nella scelta terepeutica le potenzialità che ha il farmaco di non influire negativamente su un quadro motorio già gravemente compromesso, e contemporaneamente di contenere aspetti comportamentali di entità tale da compromettere il buon esito di un percorso riabilitativo. Alla luce di quanto detto, l’agonismo D2 dovrebbe non interferire con i livelli fisiologici di dopamina nelle vie deputate al corretto funzionamento della motricità e del sistema endocrino, risparmiando quindi ai pazienti effetti secondari quali i sintomi extrapiramidali e l’iperprolattinemia, che si avrebbero con il blocco dei recettori dopaminergici delle vie nigrostriatali, mesocorticali e tuberoinfundibolari. Inoltre, per ciò che riguarda la sintomatologia negativa, l’agonismo dopaminergico dovrebbe ripristinare un’adeguata attività dopaminergica nelle vie in cui questa è deficitaria, come può essere la via mesocorticale. A differenza di quanto accade nella schizofrenia, il deficit nel caso di paziente con grave cerebrolesione acquisita è verosimilmente di natura secondaria, cioè legato alla lesione riportata. Anche se si tratta di meccanismi d’azione adottati per la schizofrenia, dunque, di frequente nei pazienti con grave cerebrolesione si assiste alla comparsa di una sintomatologia simile a quella negativa propriamente schizofrenica, con apatia, abulia, mancanza di iniziativa o, come nel nostro campione di pazienti oggetto di studio, si assiste alla comparsa di alterazioni comportamentali sul versante produttivo dell’agitazione e dell’aggressività. Un ulteriore aspetto dirimente nella scelta di un antipsicotico nel trattamento riabilitativo di questi pazienti è la sua efficacia sulla dimensione cognitiva. Sono stati reclutati 20 soggetti in regime di ricovero ordinario presso l’Unità per la Riabilitazione delle turbe Neuropsicologiche Acquisite (URNA) dell’IRCCS “E. Medea” Ass. La Nostra famiglia-Polo Veneto di Conegliano e Pieve di Soligo (TV). I soggetti sono affetti da agitazione post-lesionale come conseguenza di grave cerebrolesione acquisita (GCA). I soggetti del campione, al manifestarsi nel corso del ricovero di comportamenti aggressivi o di episodi di agitazione di entità e durata tali da necessitare trattamento clinico, sono stati trattati farmacologicamente con quetiapina. Le variazioni comportamentali sono state registrare con la scala ABS. Al momento del reclutamento, il punteggio alla scala Level of Cognitive Functioning (LCF) era compreso tra 4 e 6. Si è inoltre provveduto a reclutare un campione di controllo, comparabile per sesso, età e LCF che manifestasse alterazioni della sfera cognitiva e comportamentale, ma per il quale non fosse opportuno dal punto di vista clinico il trattamento farmacologico. Entrambi i gruppi sono stati valutati sul piano motorio con la FIM. I due gruppi di pazienti ricevono in misura uguale trattamenti riabilitativi multidisciplinari, in regime di ricovero ospedaliero. Al termine dell’osservazione, i due gruppi ( trattato e non trattato farmacologicamente) sono stati misurati e confrontati per LCF e FIM per valutare ove presente l’entità del miglioramento e se presenti o meno influenze del farmaco sul piano cognitivo e motorio nel campione che ha assunto il farmaco rispetto all’altro. Nel campione trattato è stata fatta un’analisi qualitativa per quantificare, descrivere le caratteristiche e l’andamento del disturbo comportamentale in relazione all’assunzione dell’antipsicotico, per descrivere la distribuzione dei punteggi nelle sottoscale dell’ABS in modo da definire meglio le caratteristiche del disturbo comportamentale anche in relazione a variabili quali il momento della giornata o all’eziologia del danno. Questi dati possono essere utili oltre che per coadiuvare le scelte del trattamento farmacologico, anche per fornire strumenti che possono contribuire a una piu’ appropriata gestione del disturbo comportamentale all’interno di un setting riabilitativo. I risultati dimostrano che la quetiapina riduce effettivamente la sintomatologia comportamentale; il campione che ha assunto il farmaco è risultato comunque migliorare dal punto di vista cognitivo e anche sul piano motorio. In altre parole, la quetiapina utilizzata nel paziente con grave cerebrolesione acquisita affetto da agitazione e aggressività, consente di ridurre la sintomatologia senza influenzare negativamente gli aspetti cognitivi e motori.

Texte intégralBackground. Delirium is a neuropsychiatric syndrome more frequent in advanced cancer patients. The Memorial Delirium Assessment Scale (MDAS) is a validated tool used for diagnosis, severity and measuring phenomenology of delirium. The aim of this study is to compare the prevalence at admission, incidence during hospitalization and phenomenology of delirium in advanced cancer patients in two different settings: a hospice and an oncology ward. Methods. We conducted a prospective observational study of patients admitted at Hospice Bentivoglio of the Hospice MT Chiantore Seràgnoli Onlus Foundation (Bentivoglio, Bologna, Italy) (FHS) and attended by the Palliative Care Supportive Team at the Oncology Ward of the University Clinic of Navarra (Pamplona, Spain) (CUN). MDAS was administered at initial hospitalization and repeated every week. Frequency analysis, Chi-squared Pearson Test, Fisher test, Anova Test and Wilcoxon test were analyzed. Results. 227 were enrolled (176 in FHS, 51 in CUN). Delirium prevalence was 26% (46/176) FHS, 22% (11/51) CUN (p<0.585). Delirium incidence was diagnosed in 18% (31/176) of patients in FHS, in 8% (4/51) at CUN (p<0.208). At the time of discharge/death, irreversible delirium was present in 37% (65/176) of patients at FHS, in 6% (3/51) at CUN (p<0.001). In a subset of 32 patients, MDAS was compared at the time of diagnosis of delirium and one week later. In 22 patients with reversible delirium, all MDAS items showed a reduction in the level of intensity of delirium, but in 10 patients with irreversible delirium, the level of all items reminded at the same intensity. Conclusion. Delirium prevalence at admission and incidence during hospitalization was similar in both settings, but the evolution was different: in FSH at discharge/death, there was a higher prevalence of irreversible delirium. Signs of delirium can improve in reversible delirium and not worsen in irreversible delirium by early diagnosis and proper treatment.

Texte intégralENGLISH ABSTRACT Background: patients’ satisfaction for nursing care in the healthcare is an aspect that has become increasingly important over the years, not only for the nursing -as it is counted among nursing sensitive outcomes- but also at in economic and political issues. In Pediatrics, the philosophy most embraced in the Western world is Family Centered Care, which envisages the centrality of the child and his or her family unit in the entire care process. Few studies have evaluated the relationships between the experience of family caregivers regarding the care received and the organizational aspects of nursing care. Objectives: To examine the experience of family caregivers in relation to the hospitalization they have lived with their child and evaluate the relationship with the nursing care received and the care setting Methods: Cross-sectional study; multi-level data (administrative, nurses and caregivers) through convenience sampling. Participation has always been preceded by acceptance to participate in the study following the reading of the informed consent. For these analyses a sub-sample comparable with the studies in the literature was extrapolated. Nine hospitals affiliated with the Italian Pediatric Hospitals Association, located in different Italian regions, were involved in the data collection at the caregivers level. The data were collected through a web survey, at the nurse level, and through the Child HCAHPS, specially adapted and validated for the Italian context (S-CVI 0.91; ICC 0.90; Cronbach's Alpha 0.90). The data were analysed at the unit level through descriptive statistical analysis, to describe the sample and the variables of interest with central trend indices, frequencies and percentages; then, a linear regression model has been built to study the relationships between caregivers’ outcomes and the nursing (workload) and setting (pediatric hospital vs general hospital) variables. Data from to the caregivers’ survey, the Top Box approach was applied as indicated in the literature: each item was recoded as an indicator variable of whether respondents selected the most positive response option (eg "Yes, absolutely", “Always, or “rate 9-10”). All analyses were conducted using IBM SPSS statistical software, version 22. Results: Ninety-six units, 1472 nurses and 635 caregivers were involved in the study. The areas in which the highest percentage values were achieved were those relating to pain and communication with doctors and nurses. The lowest values, on were related to safety, preparation for discharge and comfort. Overall, the responses given by caregivers in pediatric hospitals were better than those reported by caregivers in general hospitals. The linear regression model showed that increasing the workload score by one point decreases the hospital's overall rating by 2.12 points; adding the type of hospital to the model, it was found that being in a pediatric hospital increases the hospital's overall rating by 0.28 points. Conclusions: this is the first study conducted in Europe that investigates the experience of caregivers in the Pediatrics through the gold standard tool for evaluating Family Centered Care, and is also the first to relate these outcomes with the characteristics of the nursing staff. These data confirm once again how nursing care can influence the hospitalization experience by impacting on the quality and care provided. In addition, these data can be very useful in identifying improvements to make pediatric nursing care increasingly family-centered and effective.

Texte intégralMucosal Lesions in patients with autoimmune bullous diseases are the most difficult to manage and tend to relapse more frequently than skin lesions. Consequentially, these lesions have a very important impact on quality of life of affected patients. PRP has recently been approved for the treatment of dermatological diseases characterized by difficult-to-treat mucosal and cutaneous ulcerated lesions. The mechanism of action is based on the its well-known repairing capacity (structural and functional) and on its ability to stimulate tissue proliferation and regeneration. PRP is very safety and side effects have not been described so far. We have currently used platelet gel on 10 patients with MBA and, despite the small number, it was possible to observe an initial assessment of the effectiveness but also the limits of this treatment. All patients showed a rapid improvement in pain symptoms with a consequent improvement in the quality of life.

Texte intégralDermoscopy is a cheap, easy to use and noninvasive diagnostic method to evaluate and follow up pigmented and nonpigmented skin lesions. In this retrospective observational study we examined dermoscopic images of 35 acquired and congenital melanocytic nevi affecting acral volar skin in children seen at the Dermatologic Unit, Sant’Orsola Malpighi Hospital, University of Bologna, from 2004 to 2011 in order to define dermoscopic features and to compare the baseline and follow up dermoscopic patterns. Significant dermoscopic changes between baseline and follow up pictures were observed in 88,6% of patients; in particular we noticed a brightening of the lesion in a high percentage of patients (80%) and a total regression in one patient in a period of time of 36 months. It is interesting to note that the brightening of the lesions occurred mainly in sites subjected to chronic mechanical stress such as soles and fingers so we hypothesize a role of repeated traumatism in changes occurring in acral melanocytic nevi in children.

Texte intégralActinic keratosis (AK) is the most common epithelial neoformation in the clinical practice. Most of the treatments of AK are “field” therapies, i.e. aimed at treating the “field of cancerization”, which consists of all the lesions, both clinical and subclinical, that develop after the accumulation of pre-neoplastic modifications due to long-term exposure to carcinogens, in this case ultraviolet (UV) radiation. Photodynamic therapy (PDT), which can be performed with the conventional technique (using red light) or with the daylight technique (using natural radiation), is widely used for the treatment of multiple AKs and field of cancerization. The recent literature has shown that nicotinamide (the active form of vitamin B3), may reduce the onset of new AKs and non-melanoma skin cancer, since it can promote DNA repair process and reduce the immunosuppression linked to UV-exposure. Only few studies have focused on the possible associations between PDT and nicotinamide, and in particular on the combined effect of PDT and nicotinamide in the treatment of AK. This study aims to compare the efficacy of two different treatments, i.e. PDT associated with systemic nicotinamide and PDT alone, for the treatment of multiple AKs and field of cancerization in the head and neck district.

Doctoral thesis, Università degli studi di Padova, 2012. http://hdl.handle.net/11577/3425698.
Texte intégralPremessa La vitamina Kappa (K), intesa K1 o Fillochinone (PK) e K2 o Menachinone (MK), è coinvolta nella produzione non solo delle proteine della coagulazione ma anche nella produzione di proteine GLA dell’osso e della matrice che regolano la mineralizzazione ossea e le Calcificazioni Vascolari (CV). Studi in letteratura suggeriscono che basse concentrazioni di Vitamina K sono associate con aumentato rischio di fratture e calcificazioni vascolari. I pazienti (pz) in emodialisi (HD) sono ad alto rischio di tali complicanze. Noi abbiamo condotto uno studio osservazionale volto a valutare la Prevalenza del Deficit di Vitamina K e la associazione tra lo Status della Vitamina K, le Fratture Vertebrali (FV) e le CV nei pz in HD. Materiali e Metodi Studio Osservazionale Multicentrico in 387 pz in HD, 18 centri dialisi tra il nord e centro Italia. Abbiamo misurato i livelli di: vitamina K (in High-performance liquid chromatography, HPLC), Osteocalcina o Bone GLA Protein (BGP), Matrix GLA Protein (MGP) e altri biomarkers di routine. Un gruppo di soggetti sani (comparabile per età e sesso) è stato usato come controllo. La valutazione delle FV e delle CV era centralizzata e a doppio cieco. Le FV erano valutate mediante analisi computerizzata scannerizzando la Radiografia della Colonna vertebrale in L-L (T5-L4). Era considerata FV una riduzione dell’altezza del corpo vertebrale >20%. La severità della FV era stimata in Lieve, Moderata e Severa (rispettivamente riduzione del: 20-25%, 25-40% e > 40%). Valutammo le CV con il metodo di Witteman (Lancet,1994). La CV era misurata dalla lunghezza del deposito calcifico lungo la parete dell’Aorta Addominale (Lieve 0.1-5cm, oderato 5.1- 10cm e severa > 10cm). Valutammo anche la presenza o assenza della calcificazione delle Arterie Iliache nella medesima Radiografia. Ogni differenza era risolta dal consensus. Risultati I pazienti in dialisi cronica presentavano importanti deficit di Vitamina K. Abbiamo inoltre trovato alta prevalenza di FV e CV. Conclusioni Questo studio, basato su una importante casistica di pazienti in dialisi del Nord e Centro Italia dimostra che un’importante frazione di tali pazienti è carente di vitamina k e che tale stato carenziale è correlato a complicanze di estremo interesse clinico, quali le FV e le CV. Su tale base si ritiene che ai pazienti con malattia renale cronica, assieme all’intake di Calcio e Vitamina D, si dovrebbe raccomandare l’assunzione di un adeguato introito di vitamina K al fine di realizzare una corretta Calcificazione dell’osso ed evitando in questo modo di causare il danno della CV. Studi aggiuntivi dovrebbero essere effettuati per investigarae il Ruolo della Vitamina K nelle Fratture Ossee e nelle CV anche nella popolazione generale

Texte intégralIntroduction: Portal vein thrombosis (PVT) is a frequent event in patients with cirrhosis. It can be treated with anticoagulants, but the optimal management is still unclear. Aim: The aim of this study was to retrospectively analyze the natural history of portal thrombosis in cirrhotic patients and bleeding events in a large cohort of patients with or without anticoagulation therapy. Methods: We analyzed data from 182 patients with cirrhosis and PVT, diagnosed from January 2008 to December 2015. 81 patients were anticoagulated and 101 were untreated. Demographic characteristics, extension of portal vein thrombosis, anticoagulant treatment and hemorrhagic events were evaluated. Results: thrombosis had improved in 46 (56.8%) treated patients and in 26 (25.7%) untreated patients. The anticoagulation group had significantly better recanalization rate than the untreated group (p <0.001). The duration of treatment (p = 0.005) and twice-daily dosing (p = 0.003) were the only predictors of recanalization in treated patients. Of 46 patients who achieved recanalization, 17 (36%) had recurrent thrombosis after stopping anticoagulation therapy. Kaplan–Meier curve analysis revealed a higher survival rate in the treated group than in controls (p=0,010). Anticoagulant treatment was the only independent factor related to survival in multivariate analysis (p=0,014, HR:0,303, CI: 0.101-0.907). Bleeding complications occurred in 22 (21.8%) untreated patients and in 16 (19.7%) treated patients, only in 4 cases related to the anticoagulant treatment. Conclusions: Anticoagulant is a safe and effective treatment that leads to partial or complete recanalization of the portal venous axis in 56% of patients with cirrhosis and PVT. Duration of treatment of at least 12 months and twice-daily dosing seem associated with higher recanalization rates. Discontinuation of therapy is associated with high risk of recurrence of PVT. The anticoagulant treatment seems to improve survival in cirrhotic patients with PVT.

Texte intégralIntroduction: Portal vein thrombosis (PVT) is a frequent event in patients with cirrhosis. It can be treated with anticoagulants, but the optimal management is still unclear. Aim: The aim of this study was to retrospectively analyze the natural history of portal thrombosis in cirrhotic patients and bleeding events in a large cohort of patients with or without anticoagulation therapy. Methods: We analyzed data from 182 patients with cirrhosis and PVT, diagnosed from January 2008 to December 2015. 81 patients were anticoagulated and 101 were untreated. Demographic characteristics, extension of portal vein thrombosis, anticoagulant treatment and hemorrhagic events were evaluated. Results: thrombosis had improved in 46 (56.8%) treated patients and in 26 (25.7%) untreated patients. The anticoagulation group had significantly better recanalization rate than the untreated group (p <0.001).

Texte intégralBackground: Despite the current availability of treatments and the known association between early care and a good prognosis, the treatment demand for eating disorders (EDs) stays low if compared to the their prevalence. Fears generated by common stigmatizing attitudes toward EDs partially explain this condition. Stigma towards psychiatric disorders, with prejudice and discrimination, is a phenomenon deeply rooted in the society; while opinions towards psychotic disorders, depression and anxiety have been thoroughly studied, only a few studies explore stigmatizing trends toward EDs, especially towards anorexia nervosa (AN) and bulimia nervosa (BN). Furthermore, these researches are lacking in Italian population. To program public health interventions, able to raise awareness and improving treatment requests by potential patients, we need to understand attitudes of young people towards these issues, and how the stigmatizing contents change according to different demographic characteristics. Aims: This study aims to estimate prevalence and level of stigmatizing trends and beliefs related to AN and BN in a big Italian university students sample. Socio-demographic trends related to stigmatizing tendencies, the associations with the experiential knowledge of the problem and the causal attribution beliefs are also investigated. Methods: 2,109 participants completed an online survey with a sociodemographic card, two questionnaires related to trends and stigmatizing beliefs towards AN and BN and questions about personal experience, level of contact with patients and causal attribution beliefs. The measure of trends and stigmatizing beliefs has been done with the multi-item questionnaire SAB-BN (Stigmatizing Attitudes and Beliefs about Bulimia Nervosa - SAB-BN; McLean, 2014) translated in Italian and adapted for AN. The process of translation of the instrument was carried out according to the WHO guidelines and the translated and adapted versions were administered to a pilot group of students with the aim of improving expressions, and discrepancies in the translation. The factors selected for causal attribution were selected from previously published studies. The invitation to participate in the survey was mailed to all students enrolled in the degree programs of the university. Results: Results for AN and BN are overlapping, signalling that participants tend to assimilate the two conditions. Prevalence and level of stigmatizing trends in students are low, except in the components of Personal Responsibility and Guilt (63%) and Social Distance (about 13%). Examination of demographic differences in stigmatizing attitudes in the student sample indicated uniform attitudes but males, aged 18-25 group, and students living in family held significantly higher stigmatizing attitudes. Stigma is lower in underweight subjects. 11.52% of the sample declared a previous EDs diagnosis and 3.84% a current EDs diagnosis: in both cases, more than 90% of the sample is female. Subjects with a previous diagnosis, but not those with a currentone, report less stigmatizing attitudes. 82.79% of the sample knows people with an EDs, but this knowledge doesn’t s improve stigmatizing attitudes. More than 50% of the sample attributes a main or a fundamental role for the development of AN and BN to environmental factors, with percentages over 75% for parenting and over 80% for media influence. In contrast, more than 60% of the sample believes that genetics are little or not involved in the development of these diseases. The importance attributed to environmental factors predicts a reduction in the stigma level, while the emphasis on the lack of self-discipline increases it. Conclusions: Results provide fundamental advices in order to program preventive and anti-stigma actions, to increase the awareness relating the disorder and to improve the demand for treatments.

Texte intégralIn questa tesi di dottorato è stata effettuata una valutazione clinica, neuropsichiatrica e biochimica di pazienti affetti da diversi tipi di Mucopolisaccaridosi (MPS), con lo scopo di analizzare la storia naturale di queste patologie, e perciò la loro insorgenza e la loro progressione nel tempo, ma anche di valutare gli effetti, sulla storia naturale, delle terapie ad oggi disponibili e di individuare marcatori precoci di severità. Questo progetto di tesi è parte di un progetto multicentrico più esteso sulle mucopolisaccaridosi, che prevede anche una valutazione preclinica effettuata sui modelli murini, non riportata in questa tesi. Inoltre, il progetto ha prodotto una piattaforma informatica, accessibile da remoto da tutte le Unità Operative afferenti al progetto stesso, sulla quale sarà possibile continuare a caricare i dati nei pazienti nel corso del tempo, in modo da aumentare quanto più possibile la numerosità del campione da analizzare. Questa tesi riporta i risultati dell'analisi effettuata sui 58 pazienti MPS finora disponibili, a 3 diversi tempi di valutazione progressiva. L'analisi del campione qui valutato ha confermato come i pazienti MPS siano diagnosticati con un certo ritardo, e ciò vale soprattutto per gli affetti da MPS III, diagnosticati mediamente dopo i 5 anni di età; questo forse anche a causa delle particolari manifestazioni cliniche di questa specifica sindrome. Inoltre, tale dato potrebbe essere influenzato dall'eterogeneità del campione analizzato, che comprende sia diagnosi recenti che percorsi diagnostici datati. Il sospetto clinico su queste patologie è sicuramente aumentato negli ultimi anni e ciò indubbiamente aiuterà una diagnosi precoce. Per quanto riguarda i segni e i sintomi all'esordio, il 41% dei pazienti del campione presenta contemporaneamente più segni e sintomi, e per quasi il 30% dei soggetti MPS il sospetto che porta a formulare la diagnosi è di origine muscolo-scheletrica. Tra le MPS neuronopatiche analizzate, presentano all'esordio segni e sintomi di origine neurologica il 37.5% delle MPS II e il 38.5% delle MPS III. Quest'ultimo dato risulta particolarmente interessante, dato che comunemente si considera che il coinvolgimento periferico nelle MPS III sia relativo. Dai dati qui analizzati, ciò non sembra vero all'esordio, quando in oltre il 60% dei casi i pazienti possono presentare segni e sintomi non neurologici, dato questo importante da considerare in fase di diagnosi. Da un punto di vista neurologico, èrisultato evidente come, indipendentemente dalle diverse forme di MPS, sia neuronopatiche che non, mediamente la metà dei pazienti presenti macrocefalia alla diagnosi, con punte del 85% nel caso della MPS I. Nelle forme neuronopatiche, diversi sono i segni e i sintomi che si presentano alla diagnosi e/o in corso di progressione; in questa tesi sono stati in particolare analizzati i disturbi del linguaggio e la disabilità intellettiva. Come era già noto, l'analisi effettuata in questo lavoro di tesi conferma come la disabilità intellettiva non riceva alcun giovamento dalla somministrazione della terapia enzimatica sostitutiva, in particolare per quanto riguarda i pazienti affetti dalla forma severa di MPS II, nei quali si evidenzia un aumento significativo nel tempo del grado di severità neuro-cognitiva. Come atteso, anche le caratteristiche psichiatriche delle diverse MPS, come i disturbi del sonno e del comportamento, non ricevono beneficio dall'ERT. Alcune variabili periferiche hanno evidenziato, invece, di trarre giovamento dalla terapia sostitutiva; tuttavia, nella maggior parte dei casi si apprezza solo una tendenza a un miglioramento, mentre un miglioramento statisticamente significativo si è evidenziato per l'epatosplenomegalia e i livelli di glicosaminoglicani (GAG) urinari. In modo interessante, l'analisi qui effettuata ha messo in evidenza alcune correlazioni significative tra la concentrazione dei GAG quantitativi e il coinvolgimento neuropsichiatrico e tra i livelli urinari di eparan-solfato, identificati tramite saggio qualitativo, e le medesime problematiche. In queste patologie, l'identificazione di biomarcatori che aiutassero a comprendere, ancora in fase molto precoce di malattia, quale potrebbe essere la sua progressione, sarebbe di notevole importanza per la gestione del paziente e dei suoi famigliari, e anche per la valutazione di una corretta scelta terapeutica. E' auspicabile che in un prossimo futuro un'analisi critica di molti dati clinici e biochimici ricavati da un'ampia popolazione di pazienti consenta di identificare altri biomarcatori, utili ad una diagnosi precoce e possibilmente ad una prognosi sulla severità della sua progressione.

Texte intégralThe severity of DMT2 and its complications such as chronic kidney disease (CKD) lead to increase vascular stiffness, measurable with CAVI, and alterations in substances implicated in vascular damage like Klotho, FGF23, and Sclerostin. The aim of the study was to evaluate the role of CKD stage 1-2 and possible alterations of 25 (OH)Vitamin-D, FGF23, Klotho, and Sclerostin on early vascular damage in DMT2. Methods: Patients included: DMT2 from <10 years, age <60 years, no insulin therapy, eGFR≥60 ml/min/1.73m2, absence of vascular complications. We have evaluated CAVI, albumin-excretion-rate (ACR), 25(OH)Vitamin-D, Klotho, FGF23, and Sclerostin. 30 healthy subjects were the control for CAVI, Klotho, FGF23 and Sclerostin. Results: We enrolled 40 women and 60 men, average age 56 years (IQR: 52-59), 5-year DMT2 (IQR: 2.7-7), HbA1c 6.3% (5.8-6.7), eGFR of 95 ml/min/1.73m2. FGF23 (42±10 vs controls 29.8±11 pmol/l, p<.05) and Sclerostin (36.2±7 vs 26.6±1 pmol/l, p<.05) were increased and Klotho reduced (673±300 vs 845±330 pg/ml, p<.05). CKD (ACR≥30mg/gr; eGFR between 60-90 ml/min /1.73m2) was present in 12.6%. The mean CAVI was normal and the patients with borderline (≥8, 33%) and pathological (≥9, 13%) CAVI were older (p.001), with longer duration of DMT2 (p.022) and 25(OH)Vitamin-D lower (p.041). CAVI correlated positively with age (p.001), Hb1Ac (p.036), systolic blood pressure (SBP) (p.012) and diastolic blood pressure (DBP) (p.001) and correlated negatively with 25(OH)Vitamin-D (p.046). The multivariate analysis showed positive predictors of CAVI age (p.001), DBP (p.0001), ACR (p.008) and Klotho (p.017). Discussion: In our DMT2 population, borderline and pathological CAVI is associated with increased ACR, elevated DBP and reduced 25(OH)Vitamin-D and the alterations of FGF23, Sclerostin and Klotho, secondary to CKD, are an early sign of possible vascular damage . Conclusion: ACR, 25(OH)Vitamin-D and DBP can be modifiable risk factors for early vascular damage in DMT2.

Texte intégralIdiopathic Intracranial Hypertension (IIH) is a rare neurological disease (incidence <2/100,000/year) whose main feature is a high CSF pressure in absence of brain tumors, and mainly affect young obese women (12-20/100,000/year). IIH diagnosis is based on presence of papilloedema and on the CSF pressure measurement: according to different criteria, the lower bound is 250 or 200mmH2O. The clinical presentation is not homogeneous and the most common signs/symptoms are: headache (75% of cases), vertigo (50%), transient visual obscuration (70%), tinnitus (50%), perioptic subarachnoid space distension (80%), empty sella (75%), posterior globe flattening (60%), transverse sinus narrowing (60%). Prognosis is generally positive, although up to 25% of patients may develop long-term permanent visual loss. IIH heterogeneous presentation and rarity make planning of wide RCT difficult. Therefore, observational studies are of utility as the enable to generate preliminary results and research hypothesis that, in turn, enable to identify core-interest variables, hypothesize longitudinal trends and define sample size for prospective studies. In this report I presented the association of relevant signs/symptoms with IIH diagnosis, the impact of obesity and Binge Eating Disorder (BED) and, finally, patients’ disability profile. The first study reports a retrospective analysis of clinical, radiological and neuro-ophtalmological data referred to 115 patients undertaking diagnostic procedures. It was showed that radiological and neuro-ophtalmological signs/symptoms were more relevant than neurological ones to confirm IIH diagnosis and that the presence of 7 or more signs/symptoms was associated to IIH confirmation, which conversely did not happen with 4 or less. The second study moves from the evidence of a strong association between IIH and obesity, and between BED and obesity: obese-BED patients do not respond well to weight loss programs, but no literature exists on BED-IIH association. We included 57 patients, hospitalized for diagnostic purposes: IIH was confirmed in 38, BED in 7, six of whom had IIH (15.8%). Compared to non-obese ones, obese patients (particularly those with BED) were more likely to have IIH (P<.001), intracranial pressure >200mmH2O (P<.001) and optic nerve atrophy (P=.002). If the sub-group of IIH patients is taken into account, those with BED had higher intracranial pressure (340mmH20 vs.280 mmH20; P=.037) than the non-BED counterparts, while BMI levels were comparable. The third study moves from the paucity of studies addressing patients’ quality of life, and the lack of studies addressing disability, in patients with IIH. We enrolled 38 patients which filled in the WHODAS-12 (average score: 23.6), the MIDAS, BDI-II and SF-36. Results show a relevant disability in these patients: WHODAS-12 average score was higher than that observed in many other neurological patients. Moreover, disability associated to IIH was mostly related to headaches frequency and mood level. In conclusion, these studies are of clinical and management importance as they are based on a sample that is highly representative of daily clinical practice, i.e. patients with clinical features that enable to suppose IIH. The information herein reported opens to new perspectives for the clinical and research activities connected to a rare disease such as IIH: in the long-run, the importance of creating a network of centers with expertise in IIH and of a clinical registry; on a short-term, the importance of completing 12-months follow-up of baseline parameters.
