Studio ecografico e sierologico dell'echinococcosi cistica nei campi profughi Saharawi

Lo studio è stato condotto con lo scopo di valutare la prevalenza dell’echinococcosi cistica nella popolazione dei campi profughi Saharawi in Algeria. Per questo motivo si è provveduto allo studio ecografico dei pazienti pervenuti nelle strutture ospedaliere (totale di 263 pazienti) e al prelievo ematico nei soggetti che presentassero lesioni sospette di malattia idatidea. E’ stato rilevato un totale di 3 pazienti con cisti epatiche e altri 14 pazienti con lesioni cistiche in altri organi addominali. Gli esami sierologici svolti sui campioni ematici di questi pazienti si sono rivelati negativi per la ricerca di anticorpi diretti contro E. granulosus. In associazione si è svolto uno studio sierologico sui sieri di bambini Saharawi che si sono recati nel nostro paese in anni passati. In questo caso la positività del movimento anticorpale è stata rilevata in 5 campioni sui 35 esaminati

Evaluation of a PfHRP-2 based rapid diagnostic test versus microscopy method among HIV-positive and unknown serology patients in Ouagadougou, Burkina Faso

We evaluated the performance of a malaria rapid diagnostic test (RDT; Malaria Quick Test(®); Cypress Diagnostic) compared with the standard thick-smear microscopy method using blood samples from human immunodeficiency virus (HIV)-infected individuals and individuals of unknown HIV status collected in Ouagadougou, Burkina Faso. Our results show that 42.1% of 114 HIV-infected patients were concordantly RDT- and thick smear-positive, and 55.3% were concordantly negative. Sensitivity and specificity of the RDT test were 100.0% and 95.4%, respectively, with 5.9% false-positive results and a total agreement of 97.4%; 127 patients with unknown HIV serology were analyzed; of them, 40.9% were RDT- and thick smear-positive, and 46.4% concordantly negative. Sensitivity and specificity were 100.0% and 78.6%, respectively, with 23.5% false-positive results and a total agreement of 87.4%. Malaria Quick Test(®) is rapid and effective for the diagnosis of malaria and has a high sensitivity, confirming its use in general and HIV patients in particular

Implementation of tuberculosis prevention for exposed children, burkina faso

Objective: To develop and test a simple system for recording and reporting the diagnosis and treatment of latent tuberculosis infection and to compare the effects of passive and active tracing of child contacts on indicators of such infection. Methods: We revised Burkina Faso's latent tuberculosis infection register and quarterly tuberculosis reporting form. Subsequently, coverage of the routine screening of contacts, who were younger than five years, for active tuberculosis and the corresponding percentages of such contacts who, if eligible, initiated preventive therapy were measured, nationwide, between 1 April 2016 and 31 March 2017. In 2016, we evaluated indicators of latent tuberculosis infection in the Hauts-Bassins region before and after community health workers had begun the active tracing of contacts who were younger than five years. Findings: In Burkina Faso, during our study period, 3717 cases of pulmonary tuberculosis and 1166 corresponding contacts who were younger than five years were reported as the result of routine screening and passive contact tracing. The overall contact:index ratio was 0.31 and corresponding screening coverage was 82.0% (956/1166) and proportion of children starting on preventive treatment was 90.5% (852/941). Active tracing in Hauts-Bassins led to a substantially higher contact/index ratio (1.83) and screening coverage (99.3%; 145/146). Conclusion: The newly established recording and reporting system proved feasible and user-friendly and allowed measurement of global indicators of latent tuberculosis infection. Compared with active tracing, passive tracing led to much lower estimates of the numbers of child contacts

Burden and characteristics of the comorbidity tuberculosis - diabetes in Europe : TBnet prevalence survey and case-control study

Background: The growing burden of diabetes mellitus (DM) is posing a threat to global tuberculosis (TB) control. DM triples the risk of developing TB, modifies the presenting features of pulmonary TB, and worsens TB treatment outcomes. We aimed to analyze the prevalence of DM among TB patients and to describe the characteristics and clinical presentation of TB-DM patients in Europe. Methods: We performed a cross-sectional survey on the prevalence of DM among consecutively diagnosed adult TB patients in 11 European TB referral centers located in France, Germany, Greece, Italy, Russia, Slovakia, Spain, and the United Kingdom over the period 2007–2015. We also selected DM-TB cases and TB only controls with a 1:3 ratio to perform a case-control analysis, including patients selected from the countries mentioned above plus Norway and Ukraine. Results: Among 3143 TB enrolled patients, DM prevalence overall was 10.7% and ranged from 4.4% in Greece to 28.5% in the United Kingdom. Patients’ median ages ranged from 36 to 49 years, and all centers had >60% males; the proportion of foreign-born patients varied widely across sites. In the case-control study, DM was independently associated with older age and, among older patients, with being foreign-born. Among patients with pulmonary involvement, cavities on chest imaging were more frequently observed among those with DM. Conclusions: Diabetes mellitus represents a challenge for TB control in Europe, especially in foreign-born and in elderly patients. Specific screening strategies should be evaluated

I segni raccontano. La Lingua dei Segni Italiana tra esperienze, strumenti e metodologie

Il libro, nato dalle ricerche, esperienze, proposte e sperimentazioni presentate al 3° Convegno sulla Lingua dei Segni Italiana, racconta di una lingua che è parte della vita di molte persone sorde e udenti, e si dipana intorno a quattro tematiche: i profili professionali in evoluzione; la LIS come risorsa; le esperienze di bilinguismo e integrazione; i diritti, i servizi e l’accessibilità.The book, born from the research, experiences, proposals and experiments presented at the 3rd Conference on Italian Sign Language, tells of a language that is part of the life of many deaf and hearing people, and unfolds around four themes: professional profiles Evolving; the LIS as a resource; experiences of bilingualism and integration; rights, services and accessibility

Awareness, discussion and non-prescribed use of HIV pre-exposure prophylaxis among persons living with HIV/AIDS in Italy: a Nationwide, cross-sectional study among patients on antiretrovirals and their treating HIV physicians

Background: Before Pre-Exposure Prophylaxis (PrEP) was officially recommended and made available, a few surveys among gay and bisexual men, and persons living with HIV/AIDS (PLWHA), identified an informal use of antiretrovirals (ARVs) for PrEP among HIV-negative individuals. Before PrEP availability in Italy, we aimed to assess whether PLWHA in Italy shared their ARVs with HIV-negative individuals, whether they knew people who were on PrEP, and describe the level of awareness and discussion on this preventive measure among them and people in their close circle. Methods: Two anonymous questionnaires investigating personal characteristics and PrEP awareness, knowledge, and experience were proposed to HIV specialists and their patients on ARVs in a one-week, cross-sectional survey (December 2013-January 2014). Among PLWHA, a Multivariable Logistic Regression analysis was conducted to identify factors associated with PrEP discussion with peers (close circle and/or HIV associations), and experience (use in close circle and/or personal ARV sharing). Results: Eighty-seven specialists in 31 representative Infectious Diseases departments administered the questionnaire to 1405 PLWHA. Among specialists, 98% reported awareness, 65% knew the dosage schedule, and 14% had previously suggested or prescribed PrEP. Among PLWHA, 45.6% were somehow aware, discussed or had direct or indirect experience of PrEP: 38% "had heard" of PrEP, 24% were aware of studies in HIV-negative individuals demonstrating a risk reduction through the use of ARVs, 22% had discussed PrEP, 12% with peers; 9% reported PrEP use in close circle and 1% personal ARV sharing. Factors predictive of either PrEP discussion with peers or experience differed between men and women, but across all genders were mainly related to having access to information, with HIV association membership being the strongest predictor. Conclusions: At a time and place where there were neither official information nor proposals or interventions to guide public policies on PrEP in Italy, a significant number of PLWHA were aware of it, and approximately 10% reported PrEP use in their close circle, although they rarely shared their ARVs with uninfected people for this purpose. Official policies and PrEP availability, along with implementation programs, could avoid risks from uncontrolled PrEP procurement and self-administration practices
