We evaluated liposomal amphotericin B (AmBisome; Vestar, San Dimas, CA) administered to 88 immunocompetent patients (56 children) with visceral leishmaniasis (VL) caused by Leishmania infantum. Thirteen patients received 4 mg/kg on days 1-5 and 10 (total dose, 24 mg/kg), and all were cured; 42 received 3 mg/kg on days 1-5 and 10 (18 mg/kg), and 41 were cured; 32 received 3 mg/kg on days 1-4 and 10 (15 mg/kg), and 29 were cured (amastigotes were not cleared from 1 child, and 2 relapsed). One adult was cured with a total dose of 12mg/kg. The four children who were not cured received 3 mg/kg for 10 days; none had further relapses. There were no significant adverse events. For VL due to L. infantum, we recommended a total dose of AmBisome of > or = 20 mg/kg, given in > or = 5 doses of 3-4 mg/kg over > or = 10 days.
Endometriosis is defined as endometriotic tissues growing outside the uterine cavity. The cell biological processes responsible for the pathogenesis of this disease are not well understood. In order to detect differences in proliferative activity between endometria and endometriotic lesions, Ki67 staining was analysed. In addition, expression of epidermal growth factor (EGF) and its receptor was examined using immunohistochemistry. For dedifferentiation processes pointing to invasive properties of the uterine epithelium, the presence of the adhesion complex E-cadherin with the associated alpha- and beta-catenin was investigated. Specimens of endometrium in the proliferative phase of 36 patients without, and 79 patients with, endometriosis together with endometriotic lesions were studied. The study revealed a significantly reduced proliferation activity in uterine epithelium within the ectopic lesions but no differences between eutopic endometria of non-affected and affected patients. Furthermore, a lower expression of both EGF and its receptor in the epithelial cells of the ectopic glands was observed. The adhesion complex E-cadherin, together with alpha-, and beta-catenin, was slightly reduced in uterine epithelial cells of women with endometriosis and less expressed in endometriotic lesions. The results indicate that epithelial cells of endometriotic lesions are not hyperproliferative, but do appear to dedifferentiate, displaying an invasive character.
Population aging is the demographic phenomenon characterizing all countries in the world, and it is challenging the national infrastructures, in particular health systems. However, aging itself is not associated with increased medical spending, but disability and comorbidity that affect older individuals are the actual drivers for health expenditures. Therefore, if people age in better health, medical spending may be significantly reduced. Preventative interventions proved to be effective in reducing/preventing disease and disability and often found to be cost effective, include diet and exercise interventions, medications, routine disease screenings, and immunizations. Vaccination can protect older citizens against life-threatening diseases, such as influenza, pneumococcal infections, tetanus, and against diseases which adversely impact their quality of life, such as herpes zoster (HZ). Including HZ vaccination in its citizens' lifetime immunization calendar can reinforce Europe's commitment toward active, healthy aging. This paper outlines the consensus statement of a group of Italian experts on HZ.
Medical scientific societies have the core mission of producing, pooling and disseminating solid and updated scientific information. We report the successful experience of the partnership of four national Medical Scientific Societies active in Italy in producing scientific advice on vaccines and vaccination. In particular, i) the Italian Society of Hygiene, Preventive Medicine and Public Health; SitI, ii) the Italian Society of Paediatrics; SIP, iii) the “Italian Federation of General Practitioners”; FIMP, and iv) the Italian Federation of General Medicine FIMMG) have worked together since 2012 to produce shared evidence-based recommendations on vaccination schedules, namely the “Lifetime Immunization Schedule” which introduced for the first time in Italy a life-course approach to vaccination. The 2014 edition of the “Lifetime Immunization Schedule” was used as a basis to develop the 2017–2019 Italian National Prevention Plan, approved by The Italian Ministry of Health in February 2017. In this report, we present the structure, content and supporting evidence of the new 2016 “Lifetime Immunization Schedule” and we expand on the influential role of medical scientific societies in researching and advocating for effective and safe vaccination programmes’ implementation at the national level.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
