A first report of leptospirosis after liver transplantation.

Leptospirosis has been rarely reported in solid organ transplant recipients. We report the first case to our knowledge of leptospirosis in a liver transplant recipient who developed jaundice and renal insufficiency. We describe his favorable clinical progression and discuss the possible mechanisms involved in the more benign disease course. We also review the previously published cases of leptospirosis in solid organ transplant recipients. Although this disease does not appear to present any particularities in this context, we highlight the importance of clinical suspicion in this setting, particularly after liver transplantation.

Evaluation of grain yield in sorghum hybrids under water stress.

Sorghum grain yield can be significantly affected by climatic changes, especially drought and high temperature. The purpose of this study was to evaluate hybrids of grain sorghum grown under normal irrigation conditions or water stress in order to select those likely to be more tolerant of drought. Forty-nine hybrids were grown in a randomized block design experiment, with three replications. The plots consisted of four rows of 5 m length. Grain yield, weight of 1000 grains, harvest index, days to flowering, and plant height were measured. All of these characteristics were affected by water stress; however, grain yield showed the largest relative reduction. Comparison of the various genotypes showed that some hybrids had an acceptable grain yield under water stress, and maintained a high average yield compared to growth without stress. Several hybrids gave better grain yield than commercial check cultivars: 1170090, 1170092, 1170064, 1167026, 1167064, 1170093, 1167008, 1167029, 0009061, 1167092, 1105647, and 1170019 stood out for their acceptable plant height, earliness, and higher productivity.

Anatomic study of the collateral branches of the abdominal aorta of primate species Saguinus niger.

Saguinus niger is a primate of the family Callitrichidae, with a geographical distribution limited to northern Brazil, Guyanas, Suriname and Venezuela, where it inhabits rainforests along the coast. Three adult females from the Paragominas Bauxite Mine--PA were used, donated to the Laboratory of Animal Morphology Research (LAMR) of the Federal Rural University of Amazonia. These animals had died of natural causes. The arterial system was filled with latex, and the animals were fixed in 10% formalin. Afterwards, the abdominal aorta and its collateral branches were dissected. The arrangement of the abdominal aorta branches in this species showed a similar arrangement as domestic animals but differing in the formation of the coeliac trunk. The coeliac trunk originates from the abdominal aorta, and from this trunk, we found the hepatic, left gastric and splenic arteries, where the origin of these vessels was variable. These arteries originate from the coliac trunk or a common trunk originating from the coeliac trunk, a characteristic not described in other species. The other branches of the abdominal aorta from S. niger did not show great differences in origin when compared to other species.

[Splenic cyst. Review of the literature and report of 2 cases]. / Cisto esplênico. Revisão da literatura e relato de dois casos.

Splenic cysts are rare lesions. By 1978, only 651 cases had been reported. Over the years, the management of splenic cysts has changed with advances in surgical techniques. The traditional treatment of these lesions has been splenectomy. The recognition of the post splenectomy complications has led to emphasis on conservation of splenic tissue. Nowadays, the tendency is to use splenic salvage techniques: partial splenectomy, partial splenic decapsulation and laparoscopic assistance. The purpose of this paper is to review the literature, and to report two cases of splenic cysts that were treated by the conservative method.

Infeccao do trato urinario (ITU). Fatores predisponentes na evolucao da ITU em pediatria. / Urinary tract infection (UTI). Predisponent factors in the course of UTI in pediatrics

Os autores estudaram prospectivamente 160 pacientes portadores de ITU. Instituiram o tratamento convencional e seguiram os pacientes em protocolo especial. Quarenta e nove pacientes (30,62%) de ITU apresentaram fatores predisponentes no trato urinario, sendo que 34(21,25%) apresentaram ITU alta e 18 pacientes (11,25%) refluxo vesicoureteral. Apos o tratamento preconizado, 39 pacientes (24,37%) dos que apresentaram fatores predisponentes no trato urinario foram curados, salientando a cura de todos os casos de refluxo vesicoureteral. Concluiram os autores que nos casos de ITU com fatores predisponentes locais removiveis consegue-se a cura

Hipertensao arterial e estado de alcoolismo. / Arterial hypertension and alcoholism

Foram estudados 2.980 casos de alcoolismo no PSM de Juiz de Fora (MG); todos os casos apresentando sinais de ingesta recente de bebida alcoolica, motivo pelo qual procuraram assistencia medica. A hipertensao arterial (HA) foi encontrada em 68 individuos (2,28%), perfazendo 56 homens e 12 mulheres; 19 brancos, 40 pretos e 9 mulatos. A maioria da populacao estudada era jovem (15-35 anos), o mais jovem hipertenso com 15 anos e o mais velho com 65 anos. A HA foi mais frequente nos individuos pretos entre 26 e 45 anos (p< 0,05). 41,17% apresentaram-se hipertensos com alcoolismo tipo agudo e 58,83% hipertensos com alcoolismo tipo cronico. Conclui-se que a HA na populacao alcoolatra estudada coincide com a maior frequencia da HA essencial que incide sobre a raca masculina jovem
