BACKGROUND Computer Tomography (CT) is considered the gold standard for assessing the morphological changes of lung parenchyma. Although novel CT techniques have substantially decreased the radiation dose, radiation exposure is still high. Magnetic Resonance Imaging (MRI) has been established as a radiation- free alternative to CT for several lung diseases,(More)
RT-PCR is the most sensitive assay for diagnosis of influenza, due to enhanced rapidity and sensitivity as compared to classical methods. Hemi-nested RT-PCR was developed, targeting NP gene for influenza A and NS gene for influenza B, based on a previous single round RT-PCR method. The new method was compared with the previous technique for analytical(More)
Periodontitis is a multifactorial polymicrobial infection characterized by a destructive inflammatory process. Porphyromonas gingivalis, a Gram-negative anaerobic black-pigmented rod, which produces several virulence factors that stimulate human periodontal ligament cells (HPLCs) to produce various inflammatory mediators, has been implicated as a crucial(More)
The study was aimed to evaluate the malaria over/underdiagnosis and over/underprescription of antimalarial drugs. Between February and March 2007 blood samples were collected from 336 non-severe febrile outpatients attended in two peripheral Tanzanian hospitals. Microscopy and a rapid diagnostic test (RDT) were done locally and the accuracy evaluated by(More)
We investigated the prevalence and intensity of symptoms and the use of drugs for symptom control among all HIV-infected patients reporting to the outpatient clinics or wards of 15 clinical centres in central Italy, recording clinical and epidemiological data on three consecutive days. A total of 1128 patients were observed and tabulated. Their most(More)
Periodontitis is a multifactorial polymicrobial infection characterized by a destructive inflammatory process affecting tooth-supporting tissues and resulting in periodontal pocket formation, alveolar bone resorption and, eventually, tooth loss. The continuous challenge of host immune and resident cells by periodontopathogens and their virulence factors,(More)
Linezolid is used to treat patients with multidrug-resistant (MDR)/extensively drug-resistant (XDR)-tuberculosis (TB) cases, although clinical data on its safety, tolerability and efficacy are lacking. We performed a retrospective, nonrandomised, unblinded observational study evaluating the safety and tolerability of linezolid at 600 mg q.d. or b.i.d. in(More)
BACKGROUND The pathogenesis of malaria is the result of complex interactions between parasites, host and environment. Several studies have assessed the role of genetic characteristics of Plasmodium falciparum infection in the clinical severity of malaria infection comparing different genotypic determinants in mild and severe cases. The genes encoding the(More)
Immune function in acromegalic patients has been poorly investigated. The aim of this study was to evaluate the main surface antigen clusters of circulating lymphocytes in acromegaly. One hundred patients with active acromegaly (55 women and 45 men, aged 20-70 yr) and 200 healthy subjects sex- and age-matched with the patients (110 women and 90 men, aged(More)
OBJECTIVE Evidence available to date indicates that dengue viruses 1, 2, and 3 could be among the causes of acute fever in eastern Africa. Recently, four reports on dengue infection in travelers and residents have raised concerns over the occurrence of dengue fever in mainland Tanzania and in Zanzibar. The objective of this study was to provide(More)
