Avaliação da influência do estresse em modelo experimental de colite por administração de Ácido Trinitrobenzenosulfônico (TNBS) em concentração subinflamatória

Inflammatory bowel disease (IBD) is a chronic and relapsing disease caused by exaggerated response of the immune system. It represents a significant health problem by limiting the quality of life and being the main risk factor for colorectal cancer. Despite of its importance, the high worldwide incidence and being the object of research for several decades, the etiology remains unknown. Studies indicates an interaction between genetic and environmental factors which together with the intestinal microbiota, leads to an uncontrolled immune response. One of the aggravating environmental factors often discussed is stress, as the daily life of the population in general is increasingly rushed. In order to demonstrate the influence of stress on IBD, this study aimed to standardize an experimental model of colitis induced by instillation of a trinitrobenzene sulfonic acid (TNBS) noninflammatory concentration plus exposure to stress that intensify the inflammation. Therefore, an experiment was done to determine what would be the noninflammatory concentration. In this step, four different concentrations of TNBS (1, 6, 12.5 or 40mg/ml) were tested and the lowest concentration capable of inducing a noninflammatory response in the gut was defined as 1 mg/ml. Then, a second experiment was performed which induced colitis and exposed the animals to restraint stress. The results, however, showed that this stimulus was not enough to exacerbate the damage caused by the 1 mg/ml concentration of TNBS in the colon. With some changes in the protocol, the third experiment associated cold and restraint, as well as changes on the day of euthanasia, which occurred immediately after the stress session. The results of myeloperoxidase activity measurement were unexpected due to the noninflammatory concentration of TNBS caused an intestinal inflammation similar to the concentration of 40 mg/ml. However, the results of glutathione quantification and the corticosterone ...

Conduta no tratamento de gengivite ulcerativa necrosante (GUN) em serviço de urgência

Necrotizing ulcerative gingivitis is a periodontal disease which suddenly appears and presents an acute clinical course, characterized by patients' pain, discomfort and halitosis. Ulceration on papilla and marginal gingiva can be observed. For this reason, patients presenting this condition may seek dental assistance in Health Units or Graduation Institutions, being the dentist responsible for the adoption of a clinical treatment that minimizes symptomatology. The purpose of this case report is to expose and discuss aspects of clinical treatment for this disease applied to the reality of this service.

Direct retrospective comparison of adalimumab and infliximab in preventing early postoperative endoscopic recurrence after ileocaecal resection for crohn's disease: results from the MULTIPER database

Both adalimumab [ADA] and infliximab [IFX] seem to be effective in the prevention of early postoperative endoscopic recurrence [EPER] after ileocaecal resection in Crohn's disease [CD] patients. There is lack of data with direct comparison between the two agents in the postoperative scenario. The aim of this study was to compare the rates of EPER in patients treated with ADA and IFX after ileocaecal resection for CD. This was a multicentre retrospective analysis of EPER rates in CD patients after ileocaecal resections, from seven referral centres in three countries. Endoscopic recurrence was defined as Rutgeerts' score ≥ i2. The patients were allocated according to treatment to two groups: ADA or IFX. The EPER rates were compared between the two treatment groups. Among the 168 patients included in the database, 96 received anti-tumour necrosis factor [TNF] agents after resection [37 in the ADA and 59 in the IFX groups] and were included in this comparative study. The groups were comparable in all baseline characteristics, mainly age, gender, previous resections, perianal CD, and mono or combination therapy. EPER was identified in 9/37 [24.32%] in the ADA group vs 16/59 [27.12%] in the IFX group [p = 0.815]. In this retrospective direct comparison between ADA and IFX therapy after ileocaecal resection, there was no significant difference between the two anti-TNF agents in terms of EPER rates. However, prospective randomised studies are needed to confirm these data and better define the role of each agent in the prevention of EPER.

Carcinoma de células escamosas em assoalho vaginal de um bovino nelore associado a metástase em pulmão: relato de caso

The squamous cell carcinoma (SCC) is a neoplasm that affect pets and production animals and it’s very common in tropical countries like Brazil; develops in sparsely pigmented, stratified squamous epithelium and in mucosal surfaces exposed Ultraviolet action. The SCC is quite infiltrative but rarely causes metastases. Its occurrence in the female reproductive tract is recognized in the literature on cattle breeds from Europe. This case was a female bovine, Nelore, adult, who was referred to the "Hospital Veterinário Luiz Quintiliano de Oliveira" with dark brown fluid leakage and putrid odor, associated with ulcerative growth of the vagina. Because the extent of injury, the animal was euthanized and taken to the necropsy, which was observed on board structure, ulcerated and pus in the vaginal floor, infiltrated into the pelvic cavity to the serosa of the uterine body. The microscopic findings were detected neoplastic proliferation of epithelial cells in the floor and vaginal metastases in the lung parenchyma, and classified the primary tumor and metastasis as squamous cell carcinoma moderately differentiated.

Periodontite ulcerativa necrosante: tratamento fisico da superficie radicular com Er YAG laser

Necrotizing ulcerative periodontitis is associated with bacteria and predisposing risk factors. The treatment is centered in elimination and/or control of the bacteria and predisposing risk factors. However the disease acute phase could induce sequelae as periodontal tissue destruction which may be treated by periodontal surgical procedures.

Halitose bucal: importância da saburra lingual e periodontite na sua etiologia

In general the human breath doesn't have smell or it is so only lightly perceptible to the surrounding ones, varying of pleasant the unpleasant, being taken in consideration the sensibility of the person. Halitosis or bad breath doesn't truly represent a disease, being present in a considerable portion of the population. Ethiologically exist several involved factors, could make an appointment breathing, gastric intestinal, organic and psychic disturbances and mainly oral factors, being the microbial colonization of the tongue the most common, beside the pathological situations involving periodontitis, as necrotizing ulcerative gengivitis. For representing a true obstacle biopsicossocial, the halitosis it influences directally in the family life, work, the patients' atmosphere social, being its diagnosis specific, demanding in certain occasions treatment multidisciplinar. In that sense, the present study if report to a literary revision of the theme, approaching the main aspects of the development of the halitosis, as well as its biological origin and its clinical implications.
