Lupus anticoagulant: a marker for stroke and venous thrombosis in primary Sjogren's syndrome

Antiphospholipid antibodies (aPL) and antiphospholipid syndrome (APS) have been described in primary Sjogren's syndrome (pSS) with controversial findings regarding aPL prevalence and their association with thrombotic events. We evaluated 100 consecutive pSS patients (American-European criteria) and 89 age-gender-ethnicity-matched healthy controls for IgG/IgM anticardiolipin (aCL), IgG/IgM anti-beta2-glycoprotein-I (a beta 2GPI), and lupus anticoagulant (LA) (positivity according to APS Sydney's criteria). Clinical analysis followed standardized interview and physical examination assessing thrombotic and nonthrombotic APS manifestations and thrombosis risk factors. aPLs were detected in 16 % patients and 5.6 % controls (p = 0.035). LA was the most common aPL in patients (9 %), followed by a beta 2GPI (5 %) and aCL (4 %). Thrombotic events occurred in five patients [stroke in two, myocardial infarction in one and deep-vein thrombosis (DVT) in four], but in none of controls (p = 0.061). Mean age at time of stroke was 35 years. Three patients with thrombotic events (including the two with stroke) had APS (Sydney's criteria) and were positive exclusively for LA. Comparison of patients with (n = 16) and without (n = 84) aPL revealed similar mean age, female predominance, and ethnicity (p > =0.387). Frequencies of livedo reticularis (25 vs. 4.8 %, p = 0.021), stroke (12.5 vs. 0 %, p = 0.024), and DVT (18.8 vs. 1.2 %, p = 0.013) were significantly higher in APL + patients. Conversely, frequencies of hypertension, dyslipidemia, diabetes, obesity, smoking, sedentarism, and hormonal contraception were similar in patients with or without aPL (p a parts per thousand yenaEuro parts per thousand 0.253). Our study identified LA as an important marker for APS in pSS, particularly for stroke in young patients, warranting routine evaluation of these antibodies and rigorous intervention in modifiable risk factors.

The use of body circumferences for the prediction of intra-abdominal fat in obese women with polycystic ovary syndrome

Introduction: Computerizd tomography (CT) is the gold standard for the evaluation of intra- (IAF) and total (TAF) abdominal fat; however, the high cost of the procedure and exposure to radiation limit its routine use. Objective: To develop equations that utilize anthropometric measures for the estimate of IAF and TAF in obese women with polycystic ovary syndrome (PCOS). Methods: The weight, height, BMI, and abdominal (AC), waist (WC), chest (CC), and neck (NC) circumferences of thirty obese women with PCOS were measured, and their IAF and TAF were analyzed by CT. Results: The anthropometric variables AC, CC, and NC were chosen for the TAF linear regression model because they were better correlated with the fat deposited in this region. The model proposed for TAF (predicted) was: 4.63725 + 0.01483 x AC - 0.00117 x NC - 0.00177 x CC (R-2 = 0.78); and the model proposed for IAF was: IAF (predicted) = 1.88541 + 0.01878 x WC + 0.05687 x NC - 0.01529 x CC (R-2 = 0.51). AC was the only independent predictor of TAF (p < 0.01). Conclusion: The equations proposed showed good correlation with the real value measured by CT, and can be used in clinical practice.

Anatomical, Clinical and Radiographic Characteristics of Styloid Syndrome (Eagle Syndrome): a Case Report

Styloid syndrome is characterized by an elongated styloid process or calcification of the stylomandibular and stylohyoid ligament. This study describes a case of a 65-year-old woman who presented to the Stomatology Clinic, University of Marilia with temporomandibular joint pain, ear ringing and a reduced ability to open the mouth. Panoramic and posteroanterior digital radiographs showed bilateral elongation of the styloid processes, especially of the right side, whose length extended beyond the mandible angle. The diagnosis was confirmed with the association of clinical data and image examinations. The treatment options for styloid Syndrome include clinical follow-up, surgical removal of the styloid process or fracture of the elongated process. The case was managed by providing prosthetic rehabilitation and clinical follow-up, observing the level of discomfort and the benefit that could be achieved by the therapy, and avoiding surgical intervention.

Body changes: antiretroviral therapy and lipodystrophy syndrome in people living with HIV/aids

Objective: to identify the different types of morphological alterations from lipodystrophy syndrome (LS) in outpatients and relate them to the therapeutic regimen used. Method: a cross-sectional study which recruited 60 patients with HIV and LS and 79 without LS, who consented to interview and data collection from their medical notes. Results: the region most affected by lipoatrophy was the face; by lipohypertrophy, the abdomen, and by the mixed form, the alterations to the abdomen, face, and upper and lower limbs. Conclusion: among the therapeutic regimens, that comprised of zidovudine, lamivudine and efavirenz seemed to protect against LS. Nursing can act in the early identification of the changes, as well as providing guidance and support for patients affected by the changes in their body image.

Chronic pain associated with the Chikungunya Fever: long lasting burden of an acute illness

Abstract Background Chikungunya virus (CHIKV) is responsible for major epidemics worldwide. Autochthonous cases were recently reported in several European countries. Acute infection is thought to be monophasic. However reports on chronic pain related to CHIKV infection have been made. In particular, the fact that many of these patients do not respond well to usual analgesics suggests that the nature of chronic pain may be not only nociceptive but also neuropathic. Neuropathic pain syndromes require specific treatment and the identification of neuropathic characteristics (NC) in a pain syndrome is a major step towards pain control. Methods We carried out a cross-sectional study at the end of the major two-wave outbreak lasting 17 months in Réunion Island. We assessed pain in 106 patients seeking general practitioners with confirmed infection with the CHIK virus, and evaluated its impact on quality of life (QoL). Results The mean intensity of pain on the visual-analogical scale (VAS) was 5.8 ± 2.1, and its mean duration was 89 ± 2 days. Fifty-six patients fulfilled the definition of chronic pain. Pain had NC in 18.9% according to the DN4 questionnaire. Conversely, about two thirds (65%) of patients with NC had chronic pain. The average pain intensity was similar between patients with or without NC (6.0 ± 1.7 vs 6.1 ± 2.0). However, the total score of the Short Form-McGill Pain Questionnaire (SF-MPQ)(15.5 ± 5.2 vs 11.6 ± 5.2; p < 0.01) and both the affective (18.8 ± 6.2 vs 13.4 ± 6.7; p < 0.01) and sensory subscores (34.3 ± 10.7 vs 25.0 ± 9.9; p < 0.01) were significantly higher in patients with NC. The mean pain interference in life activities calculated from the Brief Pain Inventory (BPI) was significantly higher in patients with chronic pain than in patients without it (6.8 ± 1.9 vs 5.9 ± 1.9, p < 0.05). This score was also significantly higher in patients with NC than in those without such a feature (7.2 ± 1.5 vs 6.1 ± 1.9, p < 0.05). Conclusions There exists a specific chronic pain condition associated to CHIKV. Pain with NC seems to be associated with more aggressive clinical picture, more intense impact in QoL and more challenging pharmacological treatment.

Clinical evolution of patients hospitalized due to the first episode of Acute Coronary Syndrome

AIM: to assess the clinical evolution of patients hospitalized due to the first episode of Acute Coronary Syndrome (ACS) according to its clinical manifestation. METHODS: data were collected from 234 patients, hospitalized between May 2006 and July 2009 due to the first episode of an ACS, by consulting their medical records. RESULTS: 234 patients were hospitalized, 140 (59.8%) due to Acute Myocardial Infarction (AMI). In the group with AMI, 19.3% presented complications, against 12.8% in the group with Unstable Angina (UA) (p=0.19). Angioplasty levels were higher among patients with AMI than with UA (p=0.02) and coronary artery bypass graft surgery was more frequent among UA patients (p=0.03). The majority (227; 97%) survived after the coronary event. Among the seven patients who died during the hospitalization, four had AMI (2.9%) and three UA (3.2%). CONCLUSIONS: A larger number of complications were found among infarction victims and the accomplishment of coronary artery bypass graft surgery differed between the groups.

La medida del síndrome de Burnout en deportistas: una perspectiva multidimensional

[ES] El objetivo fundamental de este trabajo es comparar dos instrumentos de medida del burnout en deportistas: el Inventario de Burnout en Deportistas-Revisado (IBD-R) y el Athlete Burnout Questionnaire (ABQ). Ambos modelos de medida asumen una composición tridimensional del síndrome existiendo supuestamente un paralelismo conceptual entre dimensiones. Los análisis de correlaciones realizados entre subescalas supuestamente equivalentes muestran, no obstante, que sólo existe un buen grado de convergencia entre una de las subescalas (Agotamiento Emocional del IBD-R y Agotamiento Físico y Emocional del ABQ). Otras dos subescalas que deberían converger (Reducida Realización Personal del IBD-R y Reducida Sensación de Logro del ABQ) muestran un grado de convergencia menor del esperado y las subescalas de Despersonalización del IBD-R y Devaluación de la Práctica Deportiva del ABQ apenas evidencian relación. Las disonancias teóricas y psicométricas observadas nos hacen reflexionar acerca de desarrollo de un nuevo modelo que integre los componentes del burnout no convergentes.

La partecipazione femminile al giornalismo politico-letterario. Italia e Francia tra Otto e Novecento.

By examining seven major reviews (the French “Revue des deux Mondes”, the “Revue de Paris” and the “Nouvelle Revue”; the Italian “Nuova Antologia”, the “Rassegna Nazionale”, the “Rivista europea” and the “Revue internationale”) this thesis investigate the female participation in high quality journalism in Italy and France between the 1870s and the First World War. The aim is to show that despite some obvious limitations, women found room in that apparently very ‘male’ space of culture and emerged on a considerable scale in all walks of the profession. Many women regularly published on high quality reviews. Some of them even rose to high positions on editorials board. With the exception of a few fields of knowledge – albeit fundamental to the journals’ overall structure – such as economics, finance and matters to do with the army and the colonies, women contributors covedered nearly all the range of subjects contained in this periodicals: not only fiction, but also literary criticism, travelogues, politics and others. Quality and cultural journals offered women writers a considerable space for entering the public sphere, as both authors and readers. It may thus construed on a dual plane: as an opportunity for women writers to join the new professional ranks of modern publishing, but also as an important terrain for acknowledgment of their standing as intellectuals.

Pensiero e creazione. Il theatrum philosophicum di Gilles Deleuze

Partendo dalla constatazione di un sempre maggiore utilizzo di terminologie, concetti e citazioni deleuziane all’interno delle pratiche sceniche contemporanee e nelle riflessioni ad esse legate, e prendendo atto dell’assenza di studi specifici che affrontino l’argomento nella sua complessità, il lavoro si propone di penetrare nelle opere e nelle teorie del filosofo Gilles Deleuze con uno sguardo attento al verificarne i punti di contatto bidirezionali con le arti sceniche, al fine di individuare – all’interno di un pensiero che solo raramente si è occupato direttamente di teatro, ma che del teatro ha la potenza – quel materiale che può servire da stimolo per la creazione e l’analisi della scena contemporaneo.

Applicazioni cliniche e sperimentali dell’ecografia toracica in pneumologia: la diagnostica precoce delle patologie pleuropolmonari

Lung ultrasound use is increasing in respiratory medicine thanks to its development in the latest years. Actually it allows to study diseases of the chest wall (traumas, infections, neoplasms), diaphragm (paralysis, ipokinesis), pleura (effusions, pneumothorax, thickenings, neoplasms) and lung parenchyma (consolidations, interstitial syndromes, peripheral lesions). One of the most useful application of chest ultrasound is the evaluation of effusions. However, no standardized approach for ultrasound-guided thoracenthesis is available. Our study showed that our usual ultrasonographic landmark (“V-point”) could be a standard site to perform thoracenthesis: in 45 thoracenthesis no pneumothorax occurred, drainage was always successful at first attempt. Values of maximum thickness at V-point and drained fluid volume showed a significative correlation. Proteins concentration of ultrasound patterns of effusions (anechoic, ipoechoic, moving echoic spots, dense moving spots, hyperechoic) were compared to those of the macroscopic features of fluids showing connection between light-yellow fluid and echoic moving spots pattern and between ipoechoic/dense moving spots and cloudy-yellow/serum-haematic fluids. These observations suggest that ultrasound could predict chemical-physical features of effusions. Lung ultrasound provides useful information about many disease of the lung, but actually there is not useful in obstructive bronchial diseases. Analysing diaphragmatic kinetics using M-mode through transhepatic scan we described a similarity between diaphragm excursion during an expiratory forced maneuver and the volume/time curve of spirometry. This allowed us to identify the M-mode Index of Obstruction (MIO), an ultrasound-analogue of FEV1/VC. We observed MIO values of normal subjects (9) and obstructed patients (9) comparing the two groups. FEV1/VC and MIO showed a significant correlation suggesting that MIO may be affected by airways obstruction; MIO values were significatively different between normal and obstructed so that it could identify an obstructive syndrome. The data show that it is possible to suspect the presence of obstructive syndrome of the airways using ultrasonography of the diaphragm.

La ville comme labyrinthe: réécritures d'un mythe entre les années 1950 et 1980

Entre les années 1950 et 1980, émerge une nouvelle forme de labyrinthe chez des romanciers européens comme Michel Butor, Alain Robbe-Grillet, Italo Calvino, Patrick Modiano et Alasdair Gray : un labyrinthe insaisissable et non cartographiable. Pour en rendre compte nous avons recours au modèle du rhizome, issu de la philosophie de Gilles Deleuze et de Félix Guattari, aussi bien qu'au concept d'hétérotopie de Michel Foucault. La spatialité de nos romans nous pousse à prendre en compte également les réécritures ironiques du mythe de Thésée, Ariane, le Minotaure, Dédale. Les citations et les allusions au mythe nous font remarquer la distance d'avec le modèle traditionnel et les effets de ce qu'on peut considérer comme un « bricolage mythique », dans le cadre d'un regard ironique, parodique ou satirique. La représentation romanesque du labyrinthe accentue d'un côté l'absence d'un centre, et de l'autre côté l'ouverture extrême de cet espace qu'est la ville contemporaine. En même temps, la présence de nombreux « espaces autres », les hétérotopies de Foucault, définit l'égarement des protagonistes des romans. Au fur et à mesure que les écrivains acquièrent conscience des caractéristiques « labyrinthiques » de ces espaces, celles-ci commencent à informer l'œuvre romanesque, créant ainsi un espace métafictionnel. Entre les années Cinquante et le début des années Soixante-dix, les Nouveaux romanciers français accentuent ainsi l'idée de pouvoir jouer avec les instruments de la fiction, pour exaspérer l'absence d'un sens dans la ville comme dans la pratique de l'écriture. Calvino reformule cette conception du roman, remarquant l'importance d'un sens, même s'il est caché et difficile à saisir. Pour cette raison, à la fin de l'époque que nous analysons, des auteurs comme Modiano et Gray absorbent les techniques d'écriture de ces prédécesseurs, en les faisant jouer avec la responsabilité éthique de l'auteur.

Il lavoro di tesi descrive il percorso per giungere alle linee guida di intervento scaturite dalla ricerca, per il potenziamento cognitivo ed affettivo di bambini e persone con x fragile nei contesti di casa, scuola e tempo libero.

La terapia demetilante con 5-azacitidina nelle sindromi mielodisplastiche: esperienza clinica del Nostro Istituto e correlazione con i dati biologici

Sulla base delle evidenze della letteratura (Fenaux, 2009; Lyons, JCO 2009), a partire da Settembre 2004 nel Nostro Istituto sono stati trattati 57 pazienti affetti da Sindrome Mielodisplastica (MDS) mediante terapia demetilante con 5-Azacitidina. Sono stati utilizzati differenti regimi terapeutici a seconda della classe di rischio IPSS: i pazienti a rischio basso/intermedio-1 hanno ricevuto Azacitidina 75 mg/mq/die sottocute per 5 giorni/mese (schema 5) per 8 cicli; i pazienti a rischio alto/intermedio-2 hanno ricevuto Azacitidina 50 mg/mq/die sottocute per 10 giorni/mese (schema 5+2+5) o Azacitidina 75 mg/mq/die per 7 giorni/mese (schema 7) fino a perdita della risposta. Su una casistica totale di 57 pazienti (15 a rischio basso/int-1; 41 rischio alto/int-2), l’87.7% (50 pazienti) sono risultati valutabili. Tra questi le risposte osservate sono state del 68% (34 pazienti), di cui il 14% (7 pazienti) ha ottenuto una Remissione Completa (CR) ed il 54% (27 pazienti) ha ottenuto un Hematologic Improvement (HI). La valutazione della risposta è stata eseguita secondo i criteri dell’International Working Group 2006 (IWG, Cheeson 2006). Le principali tossicità osservate sono state rappresentate da reazioni cutanee locali nel sito d’iniezione, tossicità gastrointestinale (stipsi e/o diarrea), mielotossicità, neutropenia febbrile, sepsi (3 pazienti). Tra i pazienti trattati abbiamo osservato la presenza di risposta ematologica prolungata (≥ 20 mesi) in 10 pazienti (20% dei pazienti valutabili). Inoltre, grazie alla collaborazione con il Dipartimento di Anatomia Umana dell’Università di Bologna (Prof. L. Cocco, Dott.ssa M.Y. Follo), tutti i pazienti trattati sono stati valutati per i livelli di espressione genica e metilazione del gene della fosfolipasi PI-PLC-beta1. I dati biologici così ottenuti sono stati correlati con quelli clinici, evidenziando la presenza di una correlazione tra i livelli di espressione genica e mutilazione della PI-PLC-beta1 e la risposta alla terapia demetilante con 5-Azacitidina.

Analisi del segnale elettro-oculografico per la valutazione di stati di sonnolenza

Obbiettivo: approfondire le conoscenze sul sonno attraverso l'analisi di possibili marcatori di sonnolenza, gli Slow Eye Movements, con particolare attenzione ad una specifica patologia del sonno chiamata Obstructive Sleep Apnea Syndrome (OSAS). Metodi: sono stati analizzati gli Slow Eye Movements a partire dall'output di un algoritmo automatico, già esistente, per la loro identificazione a partire dal segnale elettro-oculografico. Il lavoro è stato condotto in ambiente MATLAB. Risultati: si sono rilevate differenze in soggetti OSAS e sani: i primi mostrano un numero maggiore di SEM nell'arco della veglia. Questa attività diventa maggiore a distanze superiori dal sonno rispetto a soggetti sani. Inoltre si è riscontrato che i SEM in veglia sono associati ad un aumento di ritmo cerebrale alpha, ed una diminuzione del ritmo beta. Conclusioni: questo studio sembra validare i SEM come marcatori di sonnolenza e ne approfondisce la conoscenza. Essi potrebbero essere quindi utilizzati in ambito clinico e tecnologico per rilevare stati di sonnolenza.

La fotochemioterapia extracorporea (ECP) nel trattamento delle glomerulonefriti

I pazienti con glomerulopatie con sindrome nefrosica hanno poche opzioni di trattamento efficace. Riportiamo la nostra esperienza sull'utilizzo della fotochemioterapia extracorporea ( ECP) in 9 pazienti in cui non era stata osservata una risposta efficace/duratura alla convenzionale terapia farmacologica. L’ECP è una promettente terapia immunomodulante, che è stata utilizzata con successo nel trattamento di altre condizioni immunomediate come il rigetto nel trapianto e il GvHD. METODI: In questo studio abbiamo arruolato 9 pazienti, 5 maschi e 4 femmine, età media 32.7±8.9 anni, affetti da sindrome nefrosica e non responsivi/resistenti alle comuni terapie. Il follow-up medio è stato di 41.3±21.7 mesi. Tutti i pazienti sono stati sottoposti a cicli di fotochemioterapia extracorporea secondo il seguente schema: 1ciclo (2 sedute in 2 giorni consecutivi) ogni 15 giorni per tre mesi, seguito da 1ciclo al mese per tre mesi. Il follow up è stato effetuatio ogni 3 mesi durante il primo anno e poi ogni 12 mesi. Durante il follow up sono stati monitorati pressione arteriosa, funzione renale, marcatori diretti ed indiretti di attività della malattia e indici di flogosi. RISULTATI: attraverso l'analisi dei parametri ematochimici indici di attività di malattia, e monitorando l'eventuale progressione della malattia renale, è stato possibile dimostrare che l' ECP può rappresentare per casi selezionati di pazienti una valida ulteriore opzione terapeutica. Secondo i risultati preliminari tale trattamento risulta inoltre caratterizzato da un eccellente profilo di sicurezza . CONCLUSIONI: I risultati osservati suggeriscono che l’ECP è un trattamento efficace per i pazienti con glomenulonefriti con sindrome nefrosica, soprattutto in coloro che presentano ancora una buona funzionalità renale. Valutazioni cliniche aggiuntive dovranno aiuteranno a definire meglio la popolazione di pazienti in cui ECP sia più efficace e raccomandabile.
