Thoracic aortic aneurysm in a buck associated with caseous lymphadenitis / Aneurisma de aorta torácica associado à linfadenite caseosa em caprino reprodutor

This paper reports the clinical, bacteriological and pathological findings of a thoracic aortic aneurysm in a four-year-old Anglo-Nubian goat buck, related to a framework of visceral caseous lymphadenitis. General clinical examination showed heart rate of 75 beats per minute, respiratory rate of 20 movements per minute and ruminal movements of four movements per minute. Superficial lymph nodes were normal upon palpation. Rectal temperature was slightly high (40.5°C). Blood test showed an intense leukocytosis (54,000/µL), characterized by strong neutrophil shift to the left. At necropsy, a large blood clot was detected in the thoracic cavity. The thickening of the myocardium and dilatation of the aorta in the thoracic portion, presenting a saculiform format was also observed. A large number of abscesses were disseminated in the media and intima layers of aorta. The aorta lumen obstruction by arterial plaques consisting of inflammatory infiltrate, predominantly neutrophilic was also detected. Abscesses were found spread in turbinate, rumen, reticulum, kidneys, liver, spleen, testicles and aorta wall. The microbiological exam of exudate confirmed Corynebacterium pseudotuberculosis as the causal agent.

Este trabalho descreve os achados clínicos, bacteriológicos e patológicos de um aneurisma da aorta torácica em um reprodutor caprino da raça Anglo-Nubiana, de quatro anos de idade, relacionado a um caso de linfadenite caseosa visceral. Ao exame clínico geral observaram-se: frequência cardíaca de 75 batimentos por minuto, frequência respiratória de 20 movimentos por minuto e movimentos ruminais de quatro movimentos por minuto. Os linfonodos superficiais encontravam-se normais à palpação. A temperatura retal estava ligeiramente aumentada (40,5°C). No hemograma completo, observou-se leucocitose intensa, 54.000/µL, caracterizada por um forte desvio neutrofílico à direita. Nos achados de necropsia, observou-se, na cavidade torácica, presença de um grande coágulo de sangue. No coração, foi identificado espessamento do miocárdio. Uma dilatação na porção torácica da artéria aorta foi detectada, apresentando um aspecto saculiforme. Um grande número de abscessos estava presente nas camadas média e íntima da aorta. Observou-se, também, obstrução do lúmen da aorta por placas de infiltrado inflamatório, predominantemente neutrofílico. A disseminação de abscessos nos cornetos, rúmen, retículo, fígado, baço, rins, testículos e parede da aorta foi detectada. O exame microbiológico do exsudato confirmou o Corynebacterium pseudotuberculosis como o agente causal.

Hepatocellular carcinoma presenting as neutrophilic leukaemoid reaction--a rare entity.

Leukaemoid reaction is a rare, growth factor-driven, paraneoplastic manifestation of hepatocellular carcinoma. It may masquerade as the neutrophilic chronic myeloid leukaemia or as chronic neutrophilic leukaemia. A 52-year-old male presented with hepatosplenomegaly and severe leucocytosis. He had progressive leucocytosis, neutrophil alkaline phosphatase score elevated, liver function tests altered. FNAC from the mass in the liver revealed features of moderately differentiated hepatocellular carcinoma. The patient deteriorated within two weeks and died thereafter.

Infected Ewing's sarcoma of spine.

An unusual case of extradural, intraspinal Ewing's sarcoma with significant extraspinal extension is reported. In view of associated constitutional symptoms, suggestive signs, leucocytosis, elevated ESR and operative findings, the initial diagnosis of Pott's spine was entertained. The lesion however turned out to be infected Ewing's sarcoma on histopathology and bacteriological examination.

Acute myeloid leukemia-FAB classification and its correlation with clinico-Hematological features

The French-American and British [FAB] classification of 62 consecutive cases of acute myeloid leukemia was undertaken. AML-M2 was the commonest FAB type [32.26%], followed by Ml and M4 [22.58% each], M5 [8.6%] and M6 and M7 [1.61% each], respectively. One of the patients was diagnosed as AML-MO [not a FAB type]. The mean age of Ml, M2, M3 and M5 cases was between 25and 29 years, whereas in M4 patients it was 45.6 years. AML-M2, M4 and M5 were commoner in males, Ml in females and M3 equal in both sexes. Feeling of weakness, easy fatiguability and pallor were invariably present in all FAB types. All the patients of Ml and M5, 85% of M2, 64% of M 4 and 50% of M3 presented with fever. Bleeding manifestations were most frequent in M3 cases followed by M5, Ml, M4 and M2, respectively. Hepatomegaly and splenomegaly were relatively less prominent features in M3 as compared to other FAB types. Amongst the haematological parameters, anaemia was more severe in M1, leucocytosis in M2 and thrombocytopenia in M3 cases as compared to other FAB types

Sindrome de Sweet un paciente de 79 años / Sweet's syndrome in a 79 year old patient

1. Se presenta un típico caso de Síndrome de Sweet en una paciente de sexo femenino, de 79 años, considerándose la de más edad relatada hasta ahora. Se hace el diagnóstico clínico por la morfología, topografía, etc., juntamente con la sintomatología dolorosa y la evolución de las lesiones. 2. El laboratorio informa leve leucocitosis neutrofílica. 3. El estudio histopatologico muestra el típico infiltrado neutrofílico y edema en dermis papilar, compatible en Dermatosis Aguda Febril Neutrofílica o Síndrome de Sweet papilar, compatible con Dermatosis Aguda Febril Neutrofílica o Síndrome de Sweet. 4. El tratamiento corticoideo y antihistamínico arrojó buenos resultados. Clínicamente no había datos de interés, pero se propone mantener a la paciente bajo control, por ser el Sweet considerado un processo eventualmente paraneoplásico

Alteraciones leucocitarias en ratones portadores de sarcoma 180 / Leukocyte changes in mice bearing sarcoma 180

Se determinaron los valores avsolutos de la sdistintas poblaciones leucocitarias periféricas en ratones BALB/c normales y esplenectomizados (XB), desafiados con Sarcoma 180 sólido (S180s) y ascítico (S180a), inoculados por vías subcutánea e intraperitoneal, respectivamente. Las evaluaciones fueron realizadas al 8-, 15- y 25- día de crecimiento tumoral. Se observó: 1) leucocitosis en todos los grupos; 2) disminución del número de linfocitos al 15- y 25- día y disminución de monocitos al día 25-, en el grupo con S180s; 3) en el grupo XB, un incremento de todas las poblaciones leucocitarias, máximo entre el 8- y 15- día, valores que tendieron a normalizarse en el día 25-, en el grupo XB inoculado con S18s, neutrofilia, linfocitosis y monocitosis hasta el día 25-; 4) los valores máximos de neutrofilia correpsondieron al grupo S180a con 1905% de incremento en el día 15-, mientras que las cifras mayores de linfocitos y monocitos fueron observadas en el brupo XB inoculado con S180s en el día 15- con incrementos de 387% y 589% respectivamente, y 5) el aumento de neutrófilos fue constante en todos los grupos, observándose además altereaciones particulares en cada grupo
