Prevalence of Oral Lesions in Hospitalized Patients with Infectious Diseases in Northern Brazil

The aim of this study was to assess the prevalence of oral lesions in infectious-contagious diseases patients being treated in the University Hospital of the Federal University of Para, northern Brazil. One hundred seven patients with infectious diseases were clinically investigated for oral lesions at the University Hospital of Para, northern Brazil. From total sample, most patients were men (65.7%) with a mean age of 45.4 years. About prevalence of systemic diseases, tuberculosis was the most frequent illness, followed by AIDS, hepatitis types B and C, leishmaniasis, and meningitis. Analyzing oral manifestations, periodontal diseases and candidiasis were the most prevalent diseases in both genders, followed by recurrent aphthous ulcers, saburral tongue, simplex herpes, and squamous cell carcinoma. Of all 107 patients, only 10 males and 6 females did not present any oral manifestation. There was no statistical difference between genders with any systemic condition (P > 0.05). The great prevalence of oral manifestations in hospitalized patients with systemic disorder emphasizes the need of integral dental care in this context, aiming at a multidisciplinary approach of patients. Therefore, presence of some oral conditions, such as candidiasis, should be an alert to different systemic conditions, once in assistance with physicians; dentists can influence the early diagnosis and treatment.

Cardiac Lesions in 30 Dogs Naturally Infected With Leishmania infantum chagasi

The hearts of 30 dogs naturally infected with Leishmania infantum chagasi were evaluated histologically and immunohistochemically. Myocardial lesions were detected in all dogs, including lymphoplasmacytic myocarditis (27/30), myonecrosis (24/30), increased interstitial collagen (22/30), lepromatous-type granulomatous myocarditis (7/30), fibrinoid vascular change (3/30), and vasculitis (1/30). The parasite was detected in the hearts of 20 of 30 dogs. The number of parasitized cells correlated with the intensity of the inflammation and with the number of granulomas. The results indicate that cardiac lesions are prevalent in dogs with naturally occurring leishmaniasis even in the absence of clinical signs of cardiac disease.

Experience with the sandwich technique in endovascular thoracoabdominal aortic aneurysm repair

Background: The sandwich technique is an endovascular off-the-shelf solution for patients with thoracoabdominal aortic aneurysms (TAAAs). In a sandwich configuration, the chimney stent runs in the middle of a space created by two or three aortic endografts.Methods: All patients with TAAAs who were treated with the sandwich technique were included in the study. Self-expanding Viabahn grafts (W. L. Gore and Associates Inc, Flagstaff, Ariz) were used as parallel grafts in the renal arteries and visceral vessels. Caudad-facing chimney grafts were used for the visceral arteries and cephalad-facing periscope grafts for the renal arteries.Results: During the study period, 32 patients with TAAAs were treated with sandwich grafts. Indication for the procedure in 43% was an acute onset of symptoms, including two patients with a rupture and a retroperitoneal hematoma. Three patients required an additional debranching procedure. A total of 104 chimney grafts were implanted. Two patients died postoperatively because of the operation. Major adverse events were recorded in five patients, including one patient with persistent paraplegia and two with permanent renal failure requiring dialysis. The incidence of chimney graft occlusion was higher in patients with three or four parallel grafts than in those with two chimney grafts only. Patients with chronic dissections had a 12-times higher incidence of chimney graft occlusion than aneurysm patients. The number of patients with type I or III endoleaks was higher in the group with three or four parallel grafts.Conclusions: The sandwich technique is an off-the-shelf endovascular alternative to treat patients with TAAAs in an emergent setting. The combination of chimney grafts with a periscope configuration enables a rapid endovascular aneurysm exclusion with acceptable midterm results.

Primary relapse site pattern in women with triple-negative breast cancer

Despite the remarkable improvements in breast cancer (BC) characterization, accurate prediction of BC clinical behavior is often still difficult to achieve. Some studies have investigated the association between the molecular subtype, namely the basal-like BC and the pattern of relapse, however only few investigated the association between relapse pattern and immunohistochemical defined triple-negative breast cancers (TNBCs). The aim of this study was to evaluate the pattern of relapse in patients with TNBC, namely the primary distant relapse site:One-hundred twenty nine (129) invasive breast carcinomas with follow-up information were classified according to the molecular subtype using immunohistochemistry for ER, PgR and Her2. The association between TNBC and distant relapse primary site was analyzed by logistic regression. Using multivariate logistic regression analysis patients with TNBC displayed only 0.09(95% CI: 0.00-0.74; p = 0.02) the odds of, the non-TNBC patients of developing bone primary relapse. Regarding visceral and lymph-node relapse, no differences between in this cohort were found.Though classically regarded as aggressive tumors, TNBCs rarely development primary relapse in bone when compared to non-TNBC, a clinical relevant fact when investigating a metastasis of an occult or non-sampled primary BC.

Biologia populacional de Bryconamericus turiuba - Langeani, Lucena, Pedrini & Tarelho-Pereira, 2005 - no Rio Passa Cinco, sub-bacia do Rio Corumbataí, SP

O objetivo deste trabalho foi caracterizar a população de Bryconamericus turiuba do rio Passa Cinco com relação à estrutura em comprimento, proporção sexual, dinâmica alimentar, aspectos reprodutivos e condição corporal. O local estudado é um dos principais rios da sub-bacia do rio Corumbataí. Foram amostradas três pontos na região do alto curso contemplando trechos de ordem 2, 3 e 4. As amostragens foram realizadas ao longo de um ano e os apetrechos de pesca utilizados foram: peneira,, aparelho de pesca elétrica e covos. Foram capturados 191 indivíduos, sendo a maior quantidade no ponto 2 e na estação de cheia. A estrutura em comprimento da espécie revelou que os indivíduos não ultrapassaram 8 cm de comprimento padrão e que machos e fêmeas apresentaram comprimentos diferentes, sendo as fêmeas maiores que os machos. A proporção sexual não diferiu do esperado. Houve diferença entre os graus de gordura acumulada na cavidade visceral e graus de repleção estomacal dos peixes entre os pontos e épocas, sendo que na seca todos os indivíduos capturados apresentavam-se sem gordura. Foram analisados 49 estômagos. Onze diferentes itens alimentares foram encontrados nos conteúdos estomacais, sendo que inseto terrestre adulto apresentou-se como preferencial em alto grau. As dietas não apresentaram diferença entre os pontos de coleta nem entre as épocas. A maioria dos indivíduos com gônadas maduras foi capturada na estação seca, indicando que a reprodução ocorre neste período e estende-se por vários meses. Foram analisados 42 pares de ovários maduros. A fecundidade obtida foi 576 ovócitos, com diâmetro variando de 147 Vm a 1.176 Vm. A espécie em estudo pode ser considerada estrategista-k quanto as suas táticas reprodutivas, por possuir baixa fecundidade, pequeno porte e desova prolongada durante...(Resumo completo, clicar acesso eletrônico abaixo)

Utilização da acupuntura no tratamento de cães com discopatia intervertebral

The intervertebral disc diseases have a high casuistic in clinical routines veterinary among dogs. These conditions can cause pain, paresis or paralysis of limbs depending on the degree of injury. Clinical signs are not limited to the intervertebral disc, other anatomical parts are included. In conventional medicine, treatment may be surgical or clinical, by the use of corticosteroids with muscle relaxants. Acupuncture was an alternative to treating these diseases due to its anti-inflammatory and analgesic effects. Although there are few studies for the treatment of discopathies, acupuncture triggers the release of substances such as dynorphins, beta-endorphins and serotonin, among others; that act inhibiting somatic and visceral pain. Electroacupuncture is used to potentiate the effects of acupuncture. It can be performed with different frequencies according to the clinical evolution. However there are different opinions related to the greater efficacy in relation to acupuncture. The restraint and monitoring of the treated animal are important factors for its recovery. The association between acupuncture and conventional treatment (surgical or clinical) achieved better results than acupuncture alone. This proves that acupuncture can be considered an option in order to minimize the complications of surgery or assist in patient recovery
