Mir-661: A key Factor in Embryo-Maternal dialog With Potential Clinical Application to Predict Implantation Outcome?
2015
Implantation resulting in a full-term pregnancy is, by large, more than a passive process in which the developed conceptus is passively glued to the uterus through adhesive molecules. It is the result of a perfectly orchestrated dialog between a viable embryo and a receptive endometrium, through a mixture of paracrine and juxtacrine processes in which many key proteins and growth factors play fundamental roles (Pellicer et al., 2002.) Since their discovery, microRNAs have become prominent regulatory candidates, providing missing links for a few biological pathways in this process, although their exact role in human normal embryo formation and endometrial preparation for pregnancy remains un…
Penile dermal flap in patients with Peyronie's disease: long-term results.
2010
Purpose: In 1995 a penile dermal flap was described as an ideal operation for penile curvature due to Peyronie's disease. We report our experience with penile dermal flaps in patients with penile curvature due to Peyronie's disease. Materials and Methods: Between January 2001 and May 2004, 26 potent white men with Peyronie's disease underwent corporoplasty with a penile dermal flap. They were evaluated at 3, 6 and 12 months, and yearly thereafter by determination of penile length changes and residual curvature, and the International Index of Erectile Function-5. Results: At the maximum followup (mean 95 months, range 81 to 108) 22 of 26 patients (85%) were available for examination, of whom…
Nephron sparing surgery for renal cell carcinoma with normal contralateral kidney: 25 years of experience.
2006
We report the long-term results of our consecutive series of 504 patients who underwent NSS for cancer suspicious, solid renal tumors in the presence of a normal opposite kidney at our institution since 1979.A total of 715 patients underwent NSS since 1969, including 504 for an elective indication, that is with a normal opposite kidney. Of these patients 381 (75.6%) had RCC, 123 (24.4%) had cancer suspicious benign lesions, including 53 (10.5%) with oncocytoma, 33 (6.5%) with angiomyo(lipo)ma, 23 (4.6%) with a complicated cyst and 13 (2.8%) with other benign lesions. Of the 381 patients with RCC 283 (74.3%) had clear cell, 68 (17.8%) had papillary and 30 (7.9%) had chromophobic RCC. Mean tu…
The pathologist's role in the detection of rare variants of bladder cancer and analysis of the impact on incidence and type detection.
2018
BACKGROUND: Histology is one of the most important factors determining the prognosis of bladder cancers and rare variants are generally associated with decreased disease specific survival compared to pure transitional cell carcinomas. We believe that rare bladder cancer variants are likely underdiagnosed in the absence of a dedicated uro-pathologist in many centers. The objective of this study is to evaluate the contribution of a dedicated uro-pathologist on the identification of rare bladder cancer variants. METHODS: We retrospectively analyzed the clinical and histological records of all patients which underwent a radical cystectomy and lymph node dissection between January 2000 and Septe…
Predictors of oncological outcomes in T1G3 patients treated with BCG who undergo radical cystectomy
2018
PURPOSE: To evaluate the oncological impact of postponing radical cystectomy (RC) to allow further conservative therapies prior to progression in a large multicentre retrospective cohort of T1-HG/G3 patients initially treated with BCG. METHODS: According to the time of RC, the population was divided into 3 groups: patients who did not progress to muscle-invasive disease, patients who progressed before radical cystectomy and patients who experienced progression at the time of radical cystectomy. Clinical and pathological outcomes were compared across the three groups. RESULTS: Of 2451 patients, 509 (20.8%) underwent RC. Patients with tumors > 3 cm or with CIS had earlier cystectomies (HR = 1…
Recurrence, progression and cancer-specific mortality according to stage at re-TUR in T1G3 bladder cancer patients treated with BCG: not as bad as pr…
2018
PURPOSE: The goals of transurethral resection of a bladder tumor (TUR) are to completely resect the lesions and to make a correct diagnosis to adequately stage and treat the patient. Persistent disease after TUR is not uncommon and is why re-TUR is recommended in T1G3 patients. When there is T1 tumor in the re-TUR specimen, very high risks of progression (82%) have been reported. We analyze the risks of recurrence, progression to muscle-invasive disease and cancer-specific mortality (CSM) according to tumor stage at re-TUR in T1G3 patients treated with BCG. METHODS: In our retrospective cohort of 2451 T1G3 patients, 934 patients (38.1%) underwent re-TUR. 667 patients had residual disease (7…
Position paper on liver and kidney diseases from the Italian Association for the Study of Liver (AISF), in collaboration with the Italian Society of …
2021
Abstract Liver and kidney are strictly connected in a reciprocal manner, in both the physiological and pathological condition. The Italian Association for the Study of Liver, in collaboration with the Italian Society of Nephrology, with this position paper aims to provide an up-to-date overview on the principal relationships between these two important organs. A panel of well-recognized international expert hepatologists and nephrologists identified five relevant topics: 1) The diagnosis of kidney damage in patients with chronic liver disease; 2) Acute kidney injury in liver cirrhosis; 3) Association between chronic liver disease and chronic kidney disease; 4) Kidney damage according to dif…
Unilateral multicystic dysplastic kidney in infants exposed to antiepileptic drugs during pregnancy
2007
Prenatal exposure to antiepileptic drugs (AEDs) increases the risk of major congenital malformations (MCM) in the fetus. AED-related abnormalities include heart and neural tube defects, cleft palate, and urogenital abnormalities. Among the various congenital anomalies of the kidney and urinary tract (CAKUT), multicystic dysplastic kidney (MCDK) disease is one of the most severe expressions. Although prenatal ultrasound (US) examination has increased the prenatal diagnosis of MCDK, the pathogenesis is still unclear. We report on four cases of MCDK in infants of epileptic women treated with AEDs during pregnancy. From October 2003 to June 2006, we observed four infants with unilateral MCDK bo…
Intraspinale neurenterische Cyste mit Lungengewebsdystopie bei Myelocele

Es wird ein Fall einer kombinierten Misbildung (spinale neurenterische Cyste mit einer thorakalen Meningomyelocele) beschrieben. Das Ergebnis der neurochirurgischen Behandlung war sehr befriedigend.
Verwertbarkeit verschiedener Cysteinderivate bei langfristiger parenteraler Ernährung
1989
Utilization of cysteine derivatives for parenteral nutrition was established by means of nitrogen balance of growing rats. N,N-bis-acetylcystine and bisacetyl-glycyl-cystine were not utilized as substrates. N-acetylcysteine, glutathione disulfide, and L-thiazolidine-(4)-carboxylic acid gave evidence as suitable cysteine sources for parenteral nutrition.
