Intramedullary Endometriosis of the Conus Medullaris.

Endometriosis (EM) is a common gynecological disease characterized by endometrial-like tissue outside the uterine cavity. We report a case of intramedullary EM, a rare condition with only seven similar cases reported until today. MRI showed a mass-like lesion within the spinal canal at the L1-L2 levels and the histological and immunohistochemical features were characteristic of intraspinal endometriosis (IEM). A review of the relevant literature and a comparison between our case and seven other similar cases were made. Intraspinal EM must be recognized as a potential cause of periodic neurological signs and symptoms in young and middle-aged women. Timely intervention and appropriate management can result in control of the disease and an improvement in neurological functions.

Spermatozoa retrieval for cryopreservation after death

ABSTRACT Objectives To describe the retrieval spermatozoa technique for cryopreservation after death, including the proximal part of vas deferens. Material and Methods A 28-years old man, with previous history of infertility, who had died 12 hours before, was submitted to spermatozoa retrieval for cryopreservation, with surgical bilateral resection in bloc of the proximal part of vas deferens, testicle and epididymis. At the laboratory, by milking the epididymis and vas deferens, the extracted fluid was collected; also, three samples of each testicle parenchyma were also harvested. Results The fluid from the vas deferens showed spermatozoa, mostly with in situ motility. Testicular fragments also presented spermatozoa, mostly with small tail movements or immobile. Conclusion The inclusion of the proximal part of vas deferens during spermatozoa retrieval after death must be performed, since it contains high concentration of spermatozoa, and even in the presence of previous infertility, as was with this patient, it is possible to retrieve spermatozoa.

Avaliaçäo dos efeitos da Membrana Cirúrgica de Polímero de Tetrafluoretileno na prevençäo de aderências: estudo experimental em ratos / Evaluation of the effect of the Polymer Membrane of Tetrafluoretileno in the prevention of tacks: experimental study in rats

As aderências peritoniais säo frequentes em cirurgias abdominais e pélvicas, podendo trazer, como consequência, esterilidade, dor pélvica crônica e obstruçäo intestinal. O objetivo deste estudo é avaliar a eficácia da membrana cirúrgica de polímero de tetrafluoretileno, utilizda como barreira cirúrgica intraperitoneal, para diminuir a formaçäo de aderências. Realizou-se estudo experimental com trinta ratos Wistar, fêmeas, adultos, nos quais, através de técnicas conhecidas para desenvolver modelos de aderências intraperitoniais, criaram-se condiçöes favoráveis para estudar uma barreira cirúrgicas...

Endometriose: tratamento com agonista do GnRH a partir de lesäo induzida em ratas / Endometriosis: treatment with agonist of the GnRH from lesion induced in female rats

Os autores procuram demonstrar a eficácia do tratamento com análogo do GnRH (acetato de leuprolide) na endometriose experimental induzida em ratas. A induçao foi realizada em 80 fêmeas. OS animais do grupo tratado tiveram suas lesoes avaliadas com quatro, sete, nove e 12 semanas de tratamento. O volume de tecido endometrial sofreu uma diminuiçao significativa com o uso de droga. Conclui-se, assim, que o acetato de leuprolide faz reduçao das lesoes de forma significativa e que a técnica utilizada para a induçao da endometriose é eficaz.
