The spectrum of androgen excess disorders.
2006
A better understanding of the different phenotypes and of their endocrine and metabolic characteristics permits investigators to distinguish three main androgen excess disorders: classic polycystic ovary syndrome (PCOS), mild ovulatory PCOS, and idiopathic hyperandrogenism. These androgenic phenotypes differ more for the severity of the endocrine and metabolic alteration than for the etiopathogenetic mechanisms. The appearance of a particular androgenic phenotype is determined by a sum of genetic and environmental factors, but mostly by body weight.
Radical cystectomy or bladder preservation with radiochemotherapy in elderly patients with muscle-invasive bladder cancer: Retrospective Internationa…
2017
IF 3.156; International audience; Background: Radical cystectomy (RC) and radiochemotherapy (RCT) are curative options for muscle-invasive bladder cancer (MIBC). Optimal treatment strategy remains unclear in elderly patients.Material and methods: Patients aged 80 years old and above with T2-T4aN0-2M0-Mx MIBC were identified in the Retrospective International Study of Cancers of the Urothelial Tract (RISC) database. Patients treated with RC were compared with those treated with RCT. The impact of surgery on overall survival (OS) was assessed using a Cox proportional hazard model. Progression included locoregional and metastatic relapse and was considered a time-dependent variable.Results: Be…
A 9-Year Retained T-Tube Fragment Encased within a Stone as a Rare Cause of Jaundice
2008
Biliary diseases such as cholangitis may cause jaundice and liver damage. Here, we report on an unusual cause of jaundice in an 84-year-old man 9 years after cholecystectomy. Ultrasound analysis revealed unclear extrahepatic cholestasis and subsequent ERCP showed a large biliary stone sourrounding a T-tube fragment that had remained in the common bile duct for more than 9 years after surgery. The tip of the drainage and the stone could be successfully removed using Dormia baskets. This case suggests that plastic material accidentally left in the common bile duct favours the development of large biliary casts when present over long periods of time.
The significance of premature luteinization in an oocyte-donation programme
2006
BACKGROUND: Several evidences indicate that premature luteinization (PL) may affect IVF outcome. The primary end-point of the present study was to verify the effect of PL on the pregnancy rate (PR) of our oocytedonation programme. METHODS: PL was defined as serum progesterone ³1.2 ng/ml on the day of HCG. We analysed retrospectively 240 oocyte-donation cycles in which 120 women donated twice, with PL in the first donation cycle and no PL in the following one, acting as its own control. Recipients (n = 240) were divided in two groups according to the presence of PL (n = 120) or not (n = 120). Both groups were compared regarding donor cycle parameters and recipient cycle outcome. RESULTS: The…
Change in kidney volume after kidney transplantation in patients with autosomal polycystic kidney disease
2018
BackgroundThe indication to bilateral nephrectomy in patients with autosomal dominant polycystic kidney scheduled for kidney transplantation is controversial. Indeed, the progressive enlargement of cysts may increase the risk of complications and the need for nephrectomy. However, very few studies investigated the change in kidney volume after kidney transplantation.Material and methodsIn this prospective cohort study, the change in native kidney volume in polycystic patients was evaluated with magnetic resonance imaging. Forty patients were included in the study. Kidney diameters and total kidney volume were evaluated with magnetic resonance imaging in patients who underwent simultaneous n…
The impact of re-transurethral resection on clinical outcomes in a large multicentre cohort of patients with T1 high-grade/Grade 3 bladder cancer tre…
2015
Objectives To determine if a re-transurethral resection (TUR), in the presence or absence of muscle at the first TUR in patients with T1-high grade (HG)/Grade 3 (G3) bladder cancer, makes a difference in recurrence, progression, cancer specific (CSS) and overall survival (OS). Patients and methods In a large retrospective multicentre cohort of 2451 patients with T1-HG/G3 initially treated with bacille Calmette–Gu erin, 935 (38%) had a re-TUR. According to the presence or absence of muscle in the specimen of the primary TUR, patients were divided in four groups: group 1 (no muscle, no re-TUR), group 2 (no muscle, re-TUR), group 3 (muscle, no re-TUR) and group 4 (muscle, re-TUR). Clinical out…
Postoperative nomogram for invasive bladder cancer: does it really work? A multicenter cohort study.
2011
Objectives: Nomograms are statistical models designed to maximize predictive accuracy. We have tested the statistical correlation between the predictions of International Bladder Cancer Nomogram Consortium and the clinical outcomes in a multicenter Italian cohort of patients treated with radical cystectomy (RC) and pelvic lymph-nodes dissection. Methods and materials: Two hundred four patients who underwent RC were selected for multiple variable and then enrolled in the study. Patients were tested by the "online tool" based on the nomogram, then stratified and risk grouped for 5-year predicted disease-free survival (pDFS): low risk (67%-100%), intermediate risk (34%-66%), and high risk grou…
An increased body mass index is associated with a worse prognosis in patients administered BCG immunotherapy for T1 bladder cancer
2018
PURPOSE: The body mass index (BMI) may be associated with an increased incidence and aggressiveness of urological cancers. In this study, we aimed to evaluate the impact of the BMI on survival in patients with T1G3 non-muscle-invasive bladder cancer (NMIBC). METHODS: A total of 1155 T1G3 NMIBC patients from 13 academic institutions were retrospectively reviewed and patients administered adjuvant intravesical Bacillus Calmette-Guérin (BCG) immunotherapy with maintenance were included. Multivariable Cox regression analysis was performed to identify factors predictive of recurrence and progression. RESULTS: After re-TURBT, 288 patients (27.53%) showed residual high-grade NMIBC, while 867 (82.8…
Cholecystokinin-8 sulfate modulates the anticonvulsant efficacy of vigabatrin in an experimental model of partial complex epilepsy in the rat.
2009
Summary Purpose: We evaluated the possible additive effect induced by the administration of the anticonvulsant vigabatrin (VGB) and cholecystokinin-8 sulfate (CCK-8S) on an experimental model of partial complex seizures (maximal dentate gyrus activation, MDA). Moreover, the functional involvement of γ-aminobutyric acid (GABA) neurotransmission was tested by iontophoretically administering bicuculline (GABA receptor antagonist) in the dentate gyrus. Methods: Urethane anesthetized rats were pretreated with VGB (50, 100 or 200 mg/kg, i.p.) or CCK-8S (8 nmol/kg, i.p.) alone or coadministered with VGB (50 mg/kg, i.p.). Dentate gyrus epileptic activity was obtained through the repetitive electr…
Oculoectodermal syndrome: Report of a new case with a broad clinical spectrum
2014
Oculoectodermal syndrome (OMIM 600268) is rare and characterized by aplasia cutis congenita, epibulbar dermoids, and other abnormalities. We report herein on a newly recognized patient with oculoectodermal syndrome, which is the 19th reported patient with OES. The boy aged six years demonstrated a broad clinical spectrum of this condition, including aplasia cutis congenita, epibulbar dermoids, hyperkeratotic papule, mildly enlarged cisterna magna, and an enlarged fluid space in the quadrigeminal cistern, suggesting a cyst. He also manifested anomalies not reported associated with this disorder, including systematized epidermal nevus following Blaschko's lines, hypopigmented skin lesions, an…
