American tegumentary leishmaniasis (ATL) is an infectious disease affecting skin and mucosa, which has shown a significant increase in incidence in recent decades, has an overall prevalence of approximately 1.5 million cases annually worldwide. The present study is an analytic approach, descriptive, cross-sectional profile with the objective of establishing clinical and epidemiological correlations etiologies of cutaneous leishmaniasis in a series of cases in western Pará In the survey included 102 individuals presenting clinical manifestations of ATL, selected in from October 2009 to November 2011, attended the Center for Zoonosis Control in the city of Santarém, state of Pará variables were analyzed from the application of the chi-square tack and presented through figures and tables. The results demonstrate that prevailed infections in males 85.29%, aged 30 to 40 years 32.35%, workers and residents of rural areas engaged in occupations mostly peasants 21.57%, showed single lesions 63.72%, 77.45% ulcerated type, located in the lower limbs in 58.82% of cases, with time to disease progression of 02 months on average 74.50%. Conclusion: Six Leishmania species were identified, and the subgenus Viannia more prevalent and predominant species E (V). braziliensis.

Background and Objectives — Considering the high prevalence of stomach cancer in the northern region of Brazil and the recognized relationship between chronic gastric inflammation caused by Helicobacter pylori, and its carcinogenic potential, the objective we had with this study was to investigate the presence of the microorganism in macro and microscopic presentations of neoplasm in different regions of the stomach, and in non-malignant lesions concomitant to the adenocarcinoma in patients originating from the metropolitan area of Belém (State of Pará, Brazil). Methods - Examinations were made on 172 patients divided into two groups: group I, formed by 75 patients with gastric carcinoma, and group II, formed by 97 patients with mild enanthematic gastritis, considered control group. The diagnosis was obtained during endoscopic examination and the respective biopsy. Gastric neoplasms were classified macroscopically in accordance with Borrmann's classification, and microscopically in accordance with Laurén's classification. In group I, 54 patients were male and 21 female while in group II, 22 patients were male and 75 female. The average age in group I was 61.2 years (range 27 to 86 years), while in group II it was 37.5 years (range 16 to 69 years). Thin sections were prepared and stained using the hematoxylin-eosin method. In the Helicobacter pylori research, the modified Gram stain was utilized. Statistical analysis was done by utilizing the chi-squared (c 2) test, Mann-Whitney test (U), and Fisher's exact test. Results - The results showed the detection of Helicobacter pylori were significantly greater in patients with mild enanthematic gastritis than in patients with gastric carcinoma. The presence of Helicobacter pylori in patients with gastric carcinoma and mild enanthematic gastritis was significantly greater in the antral region than in other gastric regions. Helicobacter pylori detection in patients with gastric carcinoma did not present a significant difference in relation to the macroscopic aspect of the tumor either intestinal or diffuse histological types. Conclusions - These data suggest the presence of the bacteria is predominant in the antral region and it does not show relation with the macroscopic types or histological intestinal or diffuse types of gastric carcinoma.

INTRODUCTION: In recent years, a growing number of studies have suggested the participation of the herpes virus in periodontal disease. OBJECTIVE: this study investigates the relationship between the presence of the Epstein-Barr herpes virus and periodontal infection in patients with chronic periodontitis. METHODOLOGY: subgingival biofilm samples were collected of subgingival sites with probing depths of 4 mm to 6 mm, and > 7 of 28 patients with chronic periodontitis. The control group consisted of 16 healthy subjects without clinical evidence of chronic periodontitis. Additionally, clinical parameters of probing depth, attachment level and Bleeding index were recorded. RESULT: the results showed averages of 2 mm probing depth, 1, 7 mm attachment level and 0.3 % bleeding on probing. Investigation of the herpes virus in the subgingival biofilm of the groups was performed using polymerase chain reaction with species-specific primer. Results of viral analysis indicated the absence of EBV in all subgingival samples analyzed. CONCLUSION: these results found no relationship between the presence of the Epstein-Barr herpes virus and chronic periodontitis.
