Computerized invasive measurement of time-dependent intraocular pressure
Campos,T.V.O.; Jacobovitz,S.; Almeida,H.G.; Massensini,A.R.; Moraes,M.F.D.Several methods have been described to measure intraocular pressure (IOP) in clinical and research situations. However, the measurement of time varying IOP with high accuracy, mainly in situations that alter corneal properties, has not been reported until now. The present report describes a computerized system capable of recording the transitory variability of IOP, which is sufficiently sensitive to reliably me...
Baroreflex function in conscious rats submitted to iron overload
Cardoso,L.M.; Pedrosa,M.L.; Silva,M.E.; Moraes,M.F.D.; Colombari,E.; Chianca-Jr.,D.A.Our hypothesis is that iron accumulated in tissue, rather than in serum, may compromise cardiovascular control. Male Fischer 344 rats weighing 180 to 220 g were divided into 2 groups. In the serum iron overload group (SIO, N = 12), 20 mg elemental iron was injected ip daily for 7 days. In the tissue iron overload group (TIO, N = 19), a smaller amount of elemental iron was injected (10 mg, daily) for 5 days foll...
New concepts in hyperactive malarial splenomegaly.
Moraes, M F; Soares, M; Arroz, M J; Do Rosário, V E; Da Graça, J Pimenta; Abecasis, PHyperreactive malarial splenomegaly is thought to represent an immunological dysfunction due to recurrent episodes of malaria. The authors present a case of hyperreactive malarial splenomegaly in a patient from São Tomé e Príncipe and discuss aspects of its differential diagnosis and treatment. A revision is made of recent concepts related to its pathogenesis and relationship with lymphoproliferative disorders....
Low-cost automatic activity data recording system
Moraes,M.F.D.; Ferrarezi,C.; Mont'Alverne,F.J.A.; Garcia-Cairasco,N.We describe a low-cost, high quality device capable of monitoring indirect activity by detecting touch-release events on a conducting surface, i.e., the animal's cage cover. In addition to the detecting sensor itself, the system includes an IBM PC interface for prompt data storage. The hardware/software design, while serving for other purposes, is used to record the circadian activity rhythm pattern of rats wit...
Glass pipette-carbon fiber microelectrodes for evoked potential recordings
Moraes,M.F.D.; Garcia-Cairasco,N.Current methods for recording field potentials with tungsten electrodes make it virtually impossible to use the same recording electrode also as a lesioning electrode, for example for histological confirmation of the recorded site, because the lesioning procedure usually wears off the tungsten tip. Therefore, the electrode would have to be replaced after each lesioning procedure, which is a very high cost solut...
Cellular immune response to mycobacterial antigens.
Ordway, D; Centro de Malária e Outras Doenças Tropicais/IHMT e Hospital Egas Moniz, Lisboa.; Moraes, M F; Oliveira, L; Badura, R; Pinheiro, M NThe authors studied the immunological response before and after beginning anti-tuberculous therapy, of a previously health, HIV negative, 22 year old black male, from the Republic of Cape Verde. The patient had multiple vertebral bony lesions associated to subcutaneous abscesses. As immunological markers of antigen recognition, we measured blastogenic and cytotoxic responses and gamma-IFN secretion towards 30 k...
Hepatopulmonary syndrome.
De Oliveira, M L; Serviço de Pneumologia, Hospital Egas Moniz, Lisboa.; Moraes, M F; Pinheiro, M A; Da Graça, J P; Abecasis, PHepatopulmonary Syndrome is an uncommon clinical situation of unknown cause. It remains the focus of intense investigation and ongoing debate. The authors present a case of a 77 year old man with chronic liver disease known for 5 years, who developed central cyanoses, digital clubbing and hypoxemia. On searching for the cause of these clinical features, the diagnosis of Hepatopulmonary Syndrome was admitted and...
Kikuchi's disease. A rare cause of fever, lymphadenopathies and polyarthritis.
Moraes, M F; Serviço de Medicina II, Hospital Egas Moniz, Lisboa.; da Graça, J P; Araújo, C; de Matos, A A; de Lacerda, M J; Abecasis, PThis is a case report of a 29-year-old white female patient with Kikuchi's disease, presenting fever, polyarthritis, lymph gland enlargement, anemia, leucopenia with a relative lymphocytosis, altered liver function tests and circulating immune complexes. A literature review is made with emphasis on the etiology, clinical course and pathogenesis of this illness. ; This is a case report of a 29-year-old white fe...
Broncho-splenic fistula caused by hydatidosis.
Moraes, M F; Serviłco de Medicina Interna e Radiologia do Hospital de Egas Moniz, Unidade de Doenças Infecciosas e Parasitárias (UDIP-H.E.M.), Lisboa.To our knowledge, this is the first case report of a broncho-splenic fistula of hydatid origin. We discuss the clinical, radiological and therapeutic aspects of this rare complication of hydatid disease. ; To our knowledge, this is the first case report of a broncho-splenic fistula of hydatid origin.
