Abscesso esplênico

Splenic abscess is a rare disease usually associated with immunosuppressed states. Its diagnosis may be difficult due to non-specific symptoms . The authors report a case of a healthy woman, 42 years old, bearer of splenic and renal abscesses , treated with antibiotics and splenectomy. A review of the literature is presented with emphasis on the diagnosis and treatment

Tratamento de fístulas enterocutâneas através de sistema a vácuo com alta pressão e dieta oral normal

Enterocutaneous fistulas are associated with prolonged hospital stay, high morbidity/mortality, and increase in hospital costs. This study aims to describe the use of a vacuum system and normal oral diet in dealing with this problem. Methods: Seventy-four consecutive patients with recent and defined external postoperative fistulas were analyzed. Abdominal imaging was used to exclude abscess and distal obstruction. The fistula tract was sealed with Foley catheter, connected to a negative pressure flask, changed daily for 5, 10 or 15 days, as necessary. Normal oral diet was permitted. Results: No patient died. Serum albumin and transferrin showed significantly higher levels at the end of treatment than at the beginning. The moderate and low-output fistulas had the best results (97% closed). Forty-eight (65%) fistulas closed after five days, 16(22%) after 10 days and 4(5%) after 15 days. Treatment failed in 6(8%) patients, who subsequently underwent surgery. Only one patient with low-output did not close her fistula. The cost of the treatment was US$ 41.75/day and it was considered cost effective. Conclusions: The vacuum system demonstrated good results in the treatment of fistulas. It included simplicity, low cost, short hospital stay, absence of skin breakdown, normal eating, good nutrition and activity patterns

Avaliacão da satisfação do usuário e da qualidade dos tratamentos endodônticos em Centros de Especialidades Odontológicas da Grande Natal-RN

Objective: To evaluate the degree of users satisfaction and technical quality of endodontic treatment in specialized dental clinics (CEO) of Grande Natal / RN between 2006 and 2008. Methodology: evaluated 282 endodontically treated teeth in CEOs through clinical and radiographic examinations. A questionnaire about the clinical condition of the tooth, evaluation of care and satisfaction with treatment was applied. Data on pre-and trans-operative were noted by the patient's clinical record. Endodontically treated teeth were examined by a specialist in endodontics, which compared with previous radiographs and current ones. The collected datas were presented descriptively by absolute numbers, percentages, averages. To determine the association between the independent and dependent variables was carried out through the bivariate association test Chi-square and Fisher exact test. Results: 79.8% presented with radiographic normal and 84.4% without pain symptoms. 8.2% of the teeth were fractured and 3.2% extracted. The persistence of the periapical lesion was associated with initial periapical status (p <0.05). 91.5% of patients are satisfied with the outcome of treatment. Such satisfaction is associated with absence of pain and an adequate esthetic tooth position (p <0.05). Conclusion: endodontic treatment in specialized dental clinics have an adequate technical quality, resulting in the success of endodontic therapy performed in these centers and that users are satisfied with the treatment

Expressão imuno-histoquímica de IL-17, TGF-β1 e FOXP3 em ganulomas periapicais, cistos radiculares e cistos radiculares residuais

Periapical lesions are chronic inflammatory conditions of periradicular tissues considered direct consequences of infectious diseases resulting from pulp necrosis and subsequent progression to periapical region. The participation of the immune response and bone resorption in the formation of these lesions has been investigated, so that different cell types and cytokines have been identified as contributors to this process. In this perspective, this study aimed to evaluate the immunohistochemical expression of IL-17, TGF-β1 and FoxP3 in periapical granulomas (PGs), radicular cysts (RCs) and residual radicular cysts (RRCs), seeking a better understanding of the etiopathogenesis these periapicopatias. To this end, we selected 20 cases of GPs, 20 CRs and 10 RRCs to undergo morphological analysis and immunohistochemistry for biomarkers above, the latter being performed quantitatively using scores and average percentages of immunostaining for the analysis of IL-17 and TGF- β1, while for the FoxP3 were counted only the positive lymphocytes. The results showed statistically significant differences between TGF-β1 and FoxP3 imunoexpressions, in relation to the periapical lesions studied (p = 0.002, p <0.001, respectively) but not between IL-17 and these (p = 0.355). Furthermore, the analysis of lymphocytes FoxP3-positive revealed significant statistical differences in that refers to the intensity of inflammatory infiltrate (p = 0.003) and also regarding thickness of the epithelial lining (p = 0.009). Finally, it was observed in the case of PGs, strong positive correlation between the amount of FoxP3- positive lymphocytes and the immunohistochemical expression of TGF-β1 (r = 0.755, p<0.001), as well as moderate positive correlation between IL-17 and TGF-β1 imunoexpressions (r = 0.503, p = 0.024). Thus, we can conclude that interactions between Th17 and Treg cells seem to be established at the site of injury, suggesting the involvement of both pro-inflammatory and immunoregulatory cytokines in the pathogenesis of periapical lesions
