Six hundred thirty-two percutaneous renal biopsies were performed in 479 patients between 1965 and 1978. Complications occurred with 86 biopsies, an incidence of 8.5 per cent. Most complications (seventy-six of eighty-six) were minor, and either resolved spontaneously or did not require intervention. There were ten major complications, including 6 patients(More)
Mutator-like transposase is the most represented transposon transcript in the sugarcane transcriptome. Phylogenetic reconstructions derived from sequenced transcripts provided evidence that at least four distinct classes exist (I–IV) and that diversification among these classes occurred early in Angiosperms, prior to the divergence of Monocots/Eudicots. The(More)
Numerous reports have shown that serotonin (5-HT) has a detrimental effect on spermatogenesis and androgen synthesis. Serotonin has two mechanisms of action on the testicle: (1) vasoconstrictive changes possibly causing premature sloughing of spermatozoa, and (2) alteration of androgen metabolism. The data in our animals with the experimental varicocele(More)
A number of reports have shown that serotonin has a detrimental effect on spermatogenesis and androgen synthesis. Serotonin has 2 mechanisms of action on the testicle: 1) vasoconstrictive changes and 2) direct alterations of testicular metabolism and endocrine activity. The data in animals with the experimental varicocele clearly mimic the human situation.(More)
Priapism is a complication rarely seen in childhood leukemia. Whatever the etiology the basic pathologic feature is obstruction to venous outflow from the corpora cavernosa. The cavernous bodies are erect but the glans penis and the corpus spongiosum usually remain soft. Various forms of treatment have been advocated for the management of this condition and(More)
Anterior sacral meningocele is a rare entity. It arises from a congenital defect of the sacrum and the coccyx through which herniation of the caudal portion of the meninges and their contents occurs, forming a cyst-like structure. The cystic mass, which lies between the rectum and sacrum, produces a variety of symptoms depending on its size and contents and(More)
We herein report 4 cases of renal cell carcinoma with vena caval extension. Appropriate diagnostic studies and a planned surgical approach is the most effective treatment for intravascular spread. Accurate preoperative staging is important for a successful outcome. Although the technical challenges involved in performing a nephrectomy are substantial, these(More)
