Terminal ileum of patients who underwent colonoscopy: endoscopic, histologic an...

CONTEXT: For the diagnosis of the diseases which affect the terminal ileum, the colonoscopy allows macroscopic evaluation and the performing of biopsies. Studies with criteria for the endoscopic and histological characterization of this segment are scarce and there are still some doubts about the need of biopsies in patients with normal ileoscopy. OBJECTIVE: Study the terminal ileum of patients who underwent co...

Leiomioma benigno metastatizante de veia cava inferior: rara complicação tardia...

Large vessel tumors diagnosis is usually difficult. Benign metastasizing leiomyoma is a rare condition occurring inside peripheral vessels. There are few publications about this tumor inside inferior vena cava. A 54 years old female patient is presented with a previous hysterectomy for myomas. She complained of no specific symptoms 18 months after surgery. Computer tomography revealed a 7.5 x 3.5 x 4.0 cm mass ...

Tatumella ptyseos causing severe human infection: report of the first two Brazi...

Tatumella ptyseos is the type species of the Tatumella genus (Enterobacteriaceae). This fermentative Gram-negative rod has only rarely been reported as a cause of human infections; there is very little information about it in the medical literature. We report here the first two Brazilian cases of T. ptyseos infections, both evolving to severe sepsis.

CASE REPORT: The patient was a 35-year-old woman with epigastric pain that only occurred during menstruation, who had a history of bladder endometriosis. Endoscopy of the upper digestive tract showed norm...

Time-domain analysis of electromagnetic structures using vectorial and orthogon...

Este trabalho apresenta uma nova formulação para a simulação da propagação de campos eletromagnéticos no domínio do tempo em duas e três dimensões. Os algoritmos desenvolvidos incorporam a discretização por elementos finitos e usam as funções de base de arestas ortogonais em duas e, pela primeira vez, em três dimensões para descrever o comportamento de propagação dos campos elétrico e magnético em diferentes es...

Questing one Brazilian query: reporting 16 cases of Q fever from Minas Gerais, ...

Q fever has been considered non-existing in Brazil where reports of clinical cases still cannot be found. This case-series of 16 patients is a result of a systematic search for such illness by means of clinical and serologic criteria. Serologic testing was performed by the indirect microimmunofluorescence technique using phase I/II C. burnetii antigens. Influenza-like syndrome was the most frequent clinical for...

More about human monocytotropic ehrlichiosis in Brazil: serological evidence of...

Human Ehrlichia chaffeensis infections have been reported in North America, Asia and Europe, but only recently have human cases been reported in Brazil. Nine new human cases of E. chaffeensis infection diagnosed on a clinical and serological basis are reported. Serological tests were performed with indoor slides prepared with CDC stock DH-82 cells infected with E. chaffeensis (Arkansas strain). All but two pati...

Antibodies to Rickettsia rickettsii, Rickettsia typhi, Coxiella burnetii, Barto...

Rickettsial diseases except those belonging to spotted fever group rickettsioses are poorly studied in South America particularly in Brazil where few epidemiological reports have been published. We describe a serosurvey for Rickettsia rickettsii, R. typhi, Coxiella burnetii, Bartonella henselae, B. quintana, and Ehrlichia chaffeensis in 437 healthy people from a Brazilian rural community. The serum samples were...
