role at the various stages of production and distribution chains of consumption.
Tasting is also the instrument of wine critics and of wine contest judges.
Assessment of specialized critics and the results obtained in wine contests exert great
influence over wine market. The outcome of these evaluations, nevertheless, has
revealed poor accuracy, precision and reproducibility. Still, the wine market is strongly
influenced by such results.
This thesis introduces a revision on anatomical and physiological knowledge of
the sense organs involved in the sensory evaluation of wines. The chemical basis for the
origin of wines organoleptic characteristics regarding their appearance, aroma and oral
sensations is also analyzed.
Based on this knowledge, the causes of errors, deviations and inaccuracy in wine
tasting are then discussed, as well as how these factors contribute to illusory results at

Cytomegalovirus colitis is among the principal causes of this sympton, and colonoscopy is the gold standard examination to diagnose it. The objetive of this study is to define the main endoscopic findings in AIDS patients with CMV colitis. PATIENTS AND METHODS On two hundred forty five colonoscopies perfomed in AIDS patients, over a ten year period, sixty two examinationts in fifty one patients diagnosed cytomegalovirus colitis. Full length colonocopy with ileum intubation and multiple biopsies of all segments examined were always attempted. All diagnoses were confirmed by histologic and inmunohistochemical studies. RESULTS Total colonoscopy was possible in 97,5% of these examinations, and ileum intubation was achieved in 87,2% of them. A heterogeneous ulcerative pattern was present in 82% of these cases and in 50% of then only the proximal segments were affected. The cytomegalovirus was also found in one patient with normal mucosa on total endoscopic examination. In 10% of these exams another infectious agent was observed. CONCLUSION We may conclude that full length colonoscopy with ileum intubation and multiple biopsies of all segments, even if they are endoscopically normal, has always to be attempted in all cases of AIDS patients with diarrhea.

Remote populations are especially vulnerable to these conditions due to reduced access to screening and adequate treatment. In this context, the Belterra project was designed as a pilot taskforce to deliver gastrointestinal screening to an underserved Amazonian population and to spread knowledge and practice to local health workers. This study aimed to describe the implementation and present the results of the Belterra Project. Patients and methods The project took place between October 2014 and December 2017 in Belterra, Pará, Brazil. Public-private partnerships were obtained and were essential for funding. The project required complex logistic solutions to provide gastrointestinal screening to every inhabitant between 50 and 70 years of age, including medical equipment and personal transportation to a remote area. Subjects were asked about their medical history, and received a physical ex...

This study considered pre- (January-August 2013) and post- (October 2013-October 2014) intervention periods. We considered the time and cost of personnel, number of adverse events, audit adjustments to patient bills, and urgent requests and returns of medications to the central pharmacy. Costs were evaluated based on a 5-year analytical horizon and are reported in Brazilian Reals (R$) and US dollars (USD). The observed decrease in the mean number of events reported with regard to the automated drug-dispensing system between pre- and post-implementation periods was not significant. Importantly, the numbers are small, which limits the power of the mean comparative analysis between the two periods. A reduction in work time was observed among the nurses and administrative assistants, whereas pharmacist assistant...

Two hundred thirty-four patients (0.6%) had acute lower gastrointestinal bleeding of moderate or severe intensity. A definitive diagnosis was possible in 151 cases, 64.5% of these patients.This study was approved by the Institutional Review Board. Medical charts were reviewed.All examinations were done under sedation by the same medical team.The predominant sources of bleeding were colonic diverticula (73 patients; 31%), ischemic or infectious colitis (18 patients; 7.7%) and radiation proctitis (18 patients; 7.7%).A specific therapeutic intervention was performed on 61 of the 151 patients who had the diagnosis confirmed (40.4%), according to the source of bleeding. Most patients with postpolypectomy bleeding were treated with injection of epinephrine (40%) and clipping (40%). Patients with angiodysplasia were treated predominantly with argon plasma c...

For this purpose, 603 lymph nodes from 46 lesions were stained by the peroxidase-antiperoxidase technique. Tumor cells were detected in 22 nodes from 12 patients, mainly in the subcapsular sinuses, permitting a restaging of these patients into two groups: those now considered to have metastatic disease and those free of metastases. However, the 5-year follow-up showed no statistical differences in survival between the two groups.

Laparoscopic treatment of intussusception is rarely reported and must be considered for this clinical condition. We described a 35-year-old male with PJS who presented with rectal bleeding and abdominal pain. One duodenal polyp and two others in the jejunum, which caused intussusception, were visualized on preoperative investigation. Polyps were identified by laparoscopy and removed extracorporeally through enterotomies. All lesions were hamartomas. The patient was discharged on the third postoperative day and has been asymptomatic for more than 2 years. Laparoscopy allows an adequate access to explore and treat small bowel polyps and avoid the classic laparotomy.

Thirty-one reservoirs were implanted in 29 patients. Complications were observed in 19.3% of the cases imposing the removal of 12.9% of them. No reservoir have been lately removed because of infection or obstruction. Based on their results, the authors conclude that the totally implanted reservoir is extremely helpful for patients submitted to chemotherapy for long periods.

The colonoscopic procedure was always followed by biopsies, even in the absence of macroscopic lesions. The most frequent diagnosis was colitis due to citomegalovirus infection observed in 64 exams (27.1%) and presented with an inflammatory pattern with ulcers, followed by Cryptosporidium sp., found in 31 exams (13.1%). This infection, conversely, presented as an inflammatory non-ulcerative lesion. Others pathogens found in lower frequency were: Mycobacterium sp., Histoplasma capsulatum, Herpes simplex, Isospora sp., Giardia sp., Candida sp. and Campilobacter sp.. Neoplastic lesions, mostly Kaposy's sarcoma, were detected in 10 of the colonoscopies (4.2%). The most frequent colorectal disorders in AIDS patients detected by endoscopic procedures are citomegalovirus and Cryptosporidium in...

This thesis introduces a revision on anatomical and physiological knowledge of
the sense organs involved in the sensory evaluation of wines. The chemical basis for the
origin of wines organoleptic characteristics regarding their appearance, aroma and oral
sensations is also analyzed.
Based on this knowledge, the causes of errors, deviations and inaccuracy in wine
tasting are then discussed, as well as how these factors contribute to illusory results at
wine contests and to the assessment made by skilled critics, which is often dissociated
