El impacto de la inmunosupresión precoz en las complicaciones no asociadas al injerto hepático
2018
La falta de mejora a largo plazo de los resultados post-TH se debe en gran medida a complicaciones no asociadas al injerto en principio muy relacionadas con la exposición crónica a IS. En diferentes estudios se ha demostrado como la minimización de los ICN tiene un efecto protector en términos de toxicidad renal, metabólica, cardíaca y oncogénica. Sin embargo, no existe una evidencia sólida sobre el impacto que pueda tener la IS precoz, es decir aquella administrada en el post-trasplante inicial, y el desarrollo de dichas complicaciones. El grupo de Rodríguez-Perálvarez ha demostrado que tanto los niveles de Tac mayores de 10 ng/mL durante los primeros 15 días post-TH como la presencia de p…
Comparative histological and immunohistochemical study of ameloblastomas and ameloblastic carcinomas
2017
Background This study aimed to compare the histological and immunohistochemical characteristics of ameloblastomas (AM) and ameloblastic carcinomas (AC). Material and Methods Fifteen cases of AM and 9 AC were submitted to hematoxilin and eosin (H&E) and immunohistochemical analysis with the following antibodies: cytokeratins 5,7,8,14 and 19, Ki-67, p53, p63 and the cellular adhesion molecules CD138 (Syndecan-1), E-cadherin and β-catenin. The mean score of the expression of Ki-67 and p53 labelling index (LIs) were compared between the groups using the t test. A value of p<0.05 was considered to be statistically significant. Results All cases were positive for CKs 5, 14 and 19, but negative fo…
A short introduction to papillomavirus biology.
2003
In this report, the tropism of papillomaviruses, the structure of virions, the function of viral proteins and the use of pseudovirions for the analysis of the immune response against papillomaviruses and the search for the viral receptor are briefly described.
Pringle maneuver during open partial nephrectomy for renal tumors
2017
Introduction. Sparing kidney tissue is important because studies show that patients who have their entire kidney removed are more likely to suffer from chronic kidney disease after surgery than patients who received a kidney-sparing partial nephrectomy. The aim of study is to show the effectives of Pringle maneuver for clamping renal pedicle in order to minimize warm ischemia during open partial nephrectomy. Material and method. We retrospectively analyzed 34 patients diagnosed with cT1 renal tumors between 2012 and 2016 and underwent open partial nephrectomy in Sibiu Urology Department. During the surgery we perform clamping of renal pedicle with Satinsky clamp or with the Pringle maneuver…
Bladder tumours in children: An interesting case report of TCC with a partial inverted growth pattern.
2014
Bladder urothelial carcinoma is typically a disease of older individuals and rarely occurs below the age of 40 years. There is debate and uncertainty in the literature regarding the clinicopathologic and prognostic characteristics of bladder urothelial neoplasms in younger patients compared with older patients, although no consistent age criteria have been used to define "younger" age group categories. We report on a 16 years old girl with transitional cell carcinoma of the bladder with a partial inverted growth pattern who presented with gross hematuria. Ultrasonography revealed a papillary lesion in the bladder; cystoscopic evaluation showed a 15 mm papillary lesion with a thick stalk loc…
