Corrected transposition of the great arteries with several associated anomalies in a 68-year-old patient

Few patients with corrected transposition of the great arteries survive past 50 years of age because of the association with congenital defects, development of total atrioventricular block, and right ventricular dysfunction. We report the case of a male patient with dextrocardia in situs solitus and corrected transposition of the great arteries associated with a wide atrial septal defect and severe pulmonary valvar and subvalvar stenoses. The patient also developed a large aneurysm on the pulmonary artery, total atrioventricular block diagnosed 8 years earlier, symptoms of dysfunction of the systemic ventricle in the previous 2 years, insufficiency of the left atrioventricular valve, and aortic regurgitation. Despite all these associated anomalies, the patient developed class III cardiac decompensation only at the age of 68 years, which makes this case a rarity. The patient was clinically treated, and was discharged from the hospital in good condition.

Determinação do sexo em pintos da raça Rhode Island Red

Examinando 201 pintos de um dia da raça Rhode Island Red, de rebanho selecionado pela postura e considerando diversos caracteres, principalmente os relacionados com a côr da penugem, conseguimos acertar em 197, numa proporção de 98,01%, não relatada da bibliografia que conhecemos. Julgamos como mais importantes, os seguintes caracteres : mancha clara na asa notada em 100% dos machos e 6,30% das fêmeas; o anel claro na perna ocorreu em 91,80% dos machos e 3,70% das fêmeas. Estas duas particularidades, sòmente, permitem separação de sexo superior a 96%. O sinal junto ao ângulo posterior do olho foi observado em 95,10% das fêmeas e 36,70% dos machos; ponta da asa escura não ocorreu em um macho sequer, mas em 53.20% das fêmeas; ponta da asa clara foi notada em todos os machos e em 46,80% das fêmeas. Os demais caracteres mencionados no quadro, constituem elementos auxiliares de menor valor mas devem ser examinados para se esclarecerem dúvidas. Os erros decorreram de se dar mais importância à pinta escura na cabeça que ao anel claro na perna e à mancha no bordo da asa. O presente trabalho contribui para o esclarecimento do assunto principalmente por considerar o anel claro da perna e o sinal escuro próximo ao ângulo posterior do olho, caracteres valiosos e ainda não apontados anteriormente. Ainda mais, a observação metódica e conjunta de um grande número de atributos relacionados com o dimorfismo sexual constitui um subsídio ao esclarecimento de tão interessante questão.

Análise do tamanho e da forma do ôvo em galinhas das raças Rhode Island Red e Light Sussex e do híbrido entre essas duas raças

Size and shape in eggs of Rhode Island Red and Light Sussex breeds and in the hibrid Rhode x Sussex were studied. These characters are influenced by quantitative genes. Major and minor diameter were used for estimating size of the eggs and the ratio minor/major diameter for shape indice. It was found, in the material analyzed, that: a) the eggs laid by the sa- me chick are pratically uniform; b) the correlation coeficient between major and minor diameter is weak; c) Rhode Island Red has short eggs than Light Sussex; d) short eggs is dominant on long eggs; e) egg shape is the same in Rhode Island Red and Light Sussex breeds and different in the hibrid, which has rounder eggs than the breeds.

Comparação das raças Rhode Island Red, Light Sussex e seu mestiço: ovos, pintos e frangos

The breeds Light Sussex, Rhode Island Red and the hibrid Light Sussex x Rhode Island Red, from the Poultry Department of "Luiz de Queiroz" School of Agriculture, at Piracicaba, S. Paulo, were studied in this paper, Tre authors, analysing eggs, pullets and chick growing arrived to the following conclusion: a) eggs of the Light Sussex breed were haevier; b) the Light Sussex breed was early maturing; c) the cross studied did not show hibrid vigor.

Estudo de correlação entre a postura e dimensões da bacia em Rhode Island Red

The AA. have studied, in this paper, the correlation of egg production in yearling R. I. R. pullets and the difference between the pelvic bones, an between the pelvic bones and keel. The distances between those bones were measured by the fingers. It was suggested an index = spread of pelvic x spread of keel bone. These three data were compared with the last 30 days production and with the production to date - six months. Comparisons have been made with 285 pullets. The AA. have concluded: (a) there is a positive correlation between the spread of the pelvic bones and the last 30 days (r = + 0,23 and pr = + 0,16); (b) there is not correlation of the distance between the pelvic bories to the keel and the last 30 days (r = + 0,11 and pr = - 0,01; (c) there is positive correlation of the distance between the pelvic bones to the keel and last six months production (r = + 0,27 and pr = + 0,19); (d) the correlation of the index sugested pratically equals correlation between pelvic bones (r = + 0,27 and pr = + 0,19); (e) correlation between last 30 days production and the total egg production is high (r = + 0,55 and pr = 0,53). Is is stated that spread of the pelvic bones is a low index of actual production and the distance of the keel a low index of total egg production in R. I. R. pullets. The last month real production is a better index of the total egg production.

The influence of shell species and size on the shell selection pattern of Paguristes tortugae (Decapoda, Diogenidae) from Anchieta Island (Ubatuba, Brazil)

Shell selection by the hermit crab Paguristes tortugae Schmitt, 1933 from Anchieta Island (Brazil) was analyzed using the six most frequently occupied shell species in the field and taking into account the sexual condition of the individuals, the shell size and the shell species. The experiments were conducted under laboratory conditions and the shell species preference was estimated on the basis of the frequency that each species was chosen by the individuals. The preferred shell species and size were determined by regression analysis. The highest correlation coefficients were obtained for the relations between the hermit dimensions and shell dry weight. The ovigerous females preferred shells with larger internal volume: Leucozonia nassa (Gmelin, 1791) and Cerithium atratum (Born, 1778). In the experiment of shell size, males preferred heavier shells whereas females selected the shape characteristics of the shell, such as the aperture and the internal volume, which are probably related to the growth and offspring guarantee, respectively. In general, and independent of sex condition, P. tortugae showed significant selection among all shells utilized. The results suggest that shell selection by P. tortugae involves sexual and reproductive condition preferences.

Population and reproductive features of the western Atlantic hermit crab Pagurus criniticornis (Anomura, Paguridae) from Anchieta Island, southeastern Brazil

The population of the hermit crab Pagurus criniticornis (Dana, 1852) was studied based on seasonal abundance, size frequency distribution, sex ratio, reproductive period, fecundity and shell relationship. Specimens were collected monthly by SCUBA diving in the infralittoral area of Anchieta Island, Ubatuba. A total of 1,017 individuals was analyzed. Animal size (minimum and maximum shield length, respectively) was 0.7 and 2.9 mm for males, 0.6 and 2.8 mm for non-ovigerous females, and 1.0 and 2.5 mm for ovigerous females. The sex ratio was 1:1.29. Sexual dimorphism was recorded by the presence of males in the largest size classes. Ovigerous females were captured during all months along the year, with percentages varying from 8% (July) to 84.3% (February) in relation to the total females collected. Mean ± SD fecundity was 168 ± 125 eggs and tended to increase with increasing hermit size. Shells of four gastropod species [Cerithium atratum (Born, 1778), Morula nodulosa (Adams, 1845), Anachis lyrata (Sowerby, 1832) and Modulus modulus (Linnaeus, 1758)] were occupied by ovigerous females of P. criniticornis but fecundity was not significantly different in relation to the different shell types. The profile showed continuous and intense reproduction of P. criniticornis probably related to strategies developed to compensate for interspecific competition in the studied insular area.

Alterações nucleares das cellulas do figado nas infecções de Macacus Rhesus e M. Cynomolgus pelo virus da febre amarella

No figado de um Macacus rhesus inoculado por BEAUREPAIRE ARAGÃO com sangue deum caso benigno de febre amarella e no qual elle descreveu symptomas e lesões typicas semelhantes ás obidas por STOKES, BAUER e HUDSON pela inoculação com o virus africano no mesmo animal, encontrámos alterações nucleares da mesma natureza das assignaladas, no herpes zoster, herpes symptomatico, varicella e virus III do coelho e descriptas ora sob o nome de "inclusões acidophilas intranucleares" (LIPSCHÜTZ, GOODPASTURE), ora sob o de "degeneração oxychromatica" (LAUDA e LUGER). Alterações nucleares semelhantes da cellula hepatica encontrámos, posteriormente em 13 M. rhesus e 2 M. cynomolgus inoculados com e virus brasileiro da febre amarella o qual fôra isolado independentemente por BEAUREPAIRE ARAGÂO e depois por A. MARQUES DA CUNHA e J. MUNIZ de dois casos benignos de febre amarella, tendo sido um dos macacos injectado directamente com o sangue do doente; dois macacos foram inoculados com Aedes aegypti infectados em homem e em macaco; os animais foram anímaes empregados em passagens em serie do virus pelo macaco, e talvez esse facto explique até certo ponto, as notaveis differenças por vezes encontradas nas alterações histopathologicas do figado, visto como, em condições naturaes, o virus nunca passa directamente de homem para homem. A intensidade com que se apresenta a degeneração oxychromatica de modo algum está na dependencia das alterações do conteúdo gorduroso, necrose e necrobiose encontradas; em um caso, ella era a unica alteração presente no figado, sendo então particularmente intensa. As inclusões acidophilas intranucleares (degeneração oxychromatica) não foram encontradas em diversos M. rhesus não inoculados e mortos por causas obscuras; no entanto, em taes figados eram presentes infiltração e degeneração gordurosas associadas a alterações de necrose e necrobiose. Alguns estadios (figuras intranucleares "em borboleta" e "em ameba", v. fig. g e h, Est. colorida) sendo abundantes, facilitam, em virtude de sua configuração especial, o reconhecimento da degeneração oxychromatica em córtes feitos segundo uma technica rapida (pequenos fragmentos de figado fixados em formol aquecido a 60°C.-trinta minutos, córtes em congelação, hematoxylina, eosina, alcool absoluto, phenol-xylol-creosoto, xylol, balsamo), não tendo, afóra isso, importancia especial. Ao passo que a degeneração e infiltração gordurosa, bem como a necrose e a necrobiose da cellula hepatica apresentam variações consideraveis em sua intensidade de um para outro animal em uma passagem em serie não interrompida do virus pelo M. rhesus, chegando mesmo a faltar interamente em dois animaes cujo figado, no entanto, mostrou-se capaz de reproduzir symptomas e lesões typicas na passagem seguinte, as inclusões acidophilas intranucleares (degeneração oxychromatica), de regra, se encontram com muito maior regularidade...

Investigações sobre doenças de Psittacideos

The present paper colligates the notions acquired in previous investigations, already published, and new observations upon diseases of the psittacidae, liable to be confused with psittacosis of parrots. The author calls attention to the indifference with regard to this question shown by investigators, even by those who dealt with the study of this disease on the occasion of the latest outbreak of psittacosis, in flagrant contrast with the researches upon the alterations induced by pathogenic agents of other diseases transmissible to man, when these agents pass through animals or when the latter are depositaries of the virus. This remark considerably enhances the importance of the presence paper from a hygienic and epidemiologic point of view, representing moreover a contribution to general knowledge and to veterinary medicine. The researches carried out since the appearance of the latest outbreak of psittacosis,-which occurred simultaneously with an epizooty in parrots lodged in aviary of the park of Agua Branca (Directory of Animal Industry of the State São Paulo)-led to the verification of the frequent existence in these animals of various diseases liable to be confused with psittacosis. These diseases are due to two kinds of pathogenic agents: virus and bacteria. In the first group there are to be found the diseases occasioned by the virus of human psittacosis, discovered by Western, Bedson and Simpson, and the disease me with in parrots coming from traders in S. Paulo. The infections by bacteria of the genus Salmonella and by those of other genera belong to the second group. As differential characters of the two infections due to virus, delineated on the strength of notions drawn from a detailed experimental study and from the literature on this subject, the following are given: ¹ Samples of our virus were sent, for comparison, to various investigators of psittacosis. Amongst them, Prof. M. Rivers acceded to our request; he found its nature to be different from that of the virus of psittacosis studiedby him. We are very much obliged to him for the attention he paid to this verification. Virus of psittacosis - Infectiousness: man, monkey, rabbit, mouse, hen, canary. Neurotropic affinity. Inclusions: small, protoplasmic. Exsiccation: the virus has good power of preservation. Symptoms: inactivity, drowsiness, frequent diarrhoea, oculo-nasal discharge and cough, coma. Duration: 4 to 5 days. Bodily lesions: congestion of intestines, splenomegaly. Virus of S. Paulo - Infects only psittacidae, particularly those of the genus Amazona. No localization in the nervous system. Large, nuclear. Is rapidly destroyed. Inactivity, inappetency, adynamia (drooping of the wings, indifference, leaning its beak against the bars of the cage in order not to fall down); profuse diarrhoea, of whitish stools, at times enterorrhagia; prolonged coma. 2 to 8 days. Foci of yellowish necrosis in liver, spleen and lung. At times, congestion of intestines. Characteristic features common to the two viruses.-They act in great dilutions, filter through tight candles though being partly retained, are preserved under glycerine or Bedson's solution, are stable at 55°C. heat and are destroyed by physical and chemical agents. Both virus diseases are very seldom met with in psittacidae: only once, amongst numberless sick parrots, the author met with a disease of the virus differring from that of psittacosis. This disease, greatly transmissible to man, ought to be more frequent, if it were common in parrots. On the contrary, bacteria cause diseases in these animals with great frequency, presenting variable characters, from a severe epizootic form, rapidly mortal, to ambulatory or silent forms, for the most part developing towards a cure or assuming a chronic character. Amongst the bacteria which cause the infection of this group the salmonellae predominate and amongst them the bacterium discovered by Nocard, as well as a species which in the course of this study is characterized under the name of Salmonella nocardi. The author believes that in the epizooty from which Nocard isolated his bacterium there was association of the virus-disease inducing the epizooty of that epoch in Paris with the bacterial disease, as must have happened in Argentina, where the disease was transmitted to man, and Santillan, according to Barros, isolated from the sick parrots bacteria of the genus Salmonella. The diseases of the two groups, that due to virus and that due to bacteria, are differentiated: Virus-diseases - Evolution: rapid, nearly always followed by death. Symptoms: sadness, profuse diarrhoea, of whitish stools, at times enterorrhagia, complete inappetency, adynamia, indifference, prolonged coma. Clinical forms: acute and subacute. Lesions: Foci of necrosis in liver and spleen without cellular reaction around the focus, yellow liver, multiple serositis. Presence of protoplasmic or nuclear granulations. Bacteriology: Complete lack or inconstant presence of bacteria in the organs and blood. Infectiousness of the organs and blood after filtration: positive. Bacterial diseases - Varies from one week to a month or more, not always fatal. Sadness, partial inappetency, tremblings, intensive thirst, mucous or mucosanguineous diarrhoea, lack of adynamia (reacts to stimulations and moves well at any time of the disease, though showing little disposition to locomotion), soiling of feathers. Frustrate, acute, subacute and chronic. Hepatic and intestinal cogestion, foci of necrosis in liver, spleen and lung with cellular reaction around the focus. Lack of granulations. Constant presence of bacteria in the organs and blood. Negative. The analysis of the litterature shows that the characteristic features of the diseases in parrots referred to parrot psittacosis, more frequently approach the bacterial diseases here described of these animals, a hypothesis which is reinforced by the observation of the greater frequency of infections...
