BACKGROUND In previous publications, we demonstrated the safety and short-term efficacy of laparoscopic sleeve gastrectomy (LSG) as a final step in the treatment of morbid obesity (MO). This study aimed to assess the mid-term efficacy of LSG. METHODS We performed a retrospective review of a prospectively collected database. Between November 2004 and(More)
The efficacy of treatment with nifurtimox and/or benznidazole among adults with chronic Chagas disease with no previous electrocardiographic disturbances was evaluated over a mean follow-up of 21 years, by means of conventional serology, xenodiagnosis, clinical examination, electrocardiograms and chest X-ray. One hundred and eleven patients, between 17 and(More)
Clinical and epidemiological results of 95 treated and untreated chronic chagasic children, with an up to 24 years follow-up period are presented. This population studied in the 1/14 age bracket, residing in Santa Fe city, Argentina, was diagnosed through Chagas-specific conventional serologic reactions. Clinical examination was supplemented with(More)
This work compared the time at which negative seroconversion was detected by conventional serology (CS) and by the ELISA-F29 test on a cohort of chronic chagasic patients treated with nifurtimox or benznidazole. A retrospective study was performed using preserved serum from 66 asymptomatic chagasic adults under clinical supervision, and bi-annual(More)
The analysis of medical image, in particular Magnetic Resonance Imaging (MRI), is a very useful tool to help the neurologists on the diagnosis. One of the stages on the analysis of MRI is given by a classification based on the Markov Random Fields (MRF) method. It is possible to find in the literature several packages to carry out this analysis, and of(More)
Similarity search in a large collection of stored objects in a metric database has become a most interesting problem. The Spaghettis is an efficient metric data structure to index metric spaces. However, for real applications, when processing large volumes of data, query response time can be high enough. In this case, it is necessary to apply mechanisms in(More)
