Obstructive uropathy following aortofemoral graft surgery.

1991

Fifty patients who had undergone aorto-bifemoral bypass with a bifurcated Dacron graft for aortoiliac arteriosclerotic obliteration were examined with real-time sectorial ultrasound to screen for the presence of hydronephrosis. Hydronephrosis was detected in only 1 case. The low incidence of this complication in our cases may be due to the fact that all our patients were explored at least 1 year after surgery. Some may have developed hydronephrosis early, but this may have resolved spontaneously during the first year after the operation, thus remaining undiagnosed. Pathogenic mechanisms suggested for the development of hydronephrosis and therapeutic approaches are discussed. We conclude tha…

Risk factors for resurgery in men with artificial urinary sphincter: Role of urethral strictures

2017

Objective: The aims of the present study were to evaluate the outcome of implantation of an artificial urinary sphincter (AUS) in male patients with iatrogenic urinary incontinence and to analyse possible risk factors for resurgery, with particular focus on the effects of posterior urethral strictures (US). Methods: The outcomes of AUS implantation surgeries performed by 2 surgeons on consecutive patients between January 1999 and 2015 were evaluated retrospectively. Univariate analysis with Cox proportional hazard regression was used to assess correlations between resurgery (explantation or substitution of the urethral cuff) and risk factors. Hazard ratios (HR) associated with AUS survival …

Transurethral incision of duplex system ureteroceles in neonates: does it increase the need for secondary surgery in intravesical and ectopic cases?

2004

OBJECTIVE To evaluate the relevance of ureterocele ectopia and associated reflux on the outcome of duplex system ureteroceles (DSU) after neonatal transurethral incision (TUI). PATIENTS AND METHODS The study included 41 neonates with a diagnosis of DSU; the ureterocele was ectopic in 24 (58%). Before TUI, vesico-ureteric reflux (VUR) was present in 13 lower moieties (32%) and seven contralateral ureters (17%). TUI was always performed within the first month of life. The follow-up and management were tailored for each patient from the findings at ultrasonography, voiding cysto-urethrography and renal scintigraphy. Results of intravesical and ectopic DSU were compared using Fisher's exact tes…

Can We Clinically Distinguish Anejaculation From Retrograde Ejaculation in Patients on α1A-Blockers Therapy for Lower Urinary Tract Symptoms?

2019

To investigate the physiopathology of ejaculatory disorders (EjD) and discriminate between retrograde ejaculation (REj) and anejaculation (AEj) induced by α1A-blockers, through the association between the mean postorgasm seminal vesicle volume and the presence of sperm in midstream urine, in patients with moderate-to-severe lower urinary tract symptoms (LUTS) secondary to benign prostatic enlargement.Therapy-naïve male patients with LUTS and without previous EjD were treated with α1A-blockers. Pre- and post-treatment EjD were investigated through question 4 of the 4-item Male Sexual Function questionnaire and the Male Sexual Health Questionnaire for Ejaculatory Dysfunction Short Form (MSHQ-…

Popular uses of wild plant species for medicinal purposes in the Nebrodi Regional Park (North-Eastern Sicily, Italy)

2014

Ethnopharmacological relevance: The area of the Nebrodi Regional Park (North-Eastern Sicily, Italy) has Q3 been quantitatively investigated in an ethnobotanical study for the first time. A total of 90 wild species are used for medicinal purposes and the uses of 5 species have not previously been reported in ethnobotanical studies in Italy (e.g., the use of Arisarum vulgare O. Targ. Tozz. for the treatment of rheumatic pains, the use of Silene vulgaris (Moench) Garcke for the treatment of liver diseases). Aim of the study: The aim of this paper was to understand to what extent current knowledge on the medicinal use of plants is still an element of the culture within the rural populations of …

Neurotransmitter receptor density changes in Pitx3ak mice – A model relevant to Parkinson’s disease

2014

Abstract Parkinson’s disease (PD) is the second most common neurodegenerative disorder, characterized by alterations of nigrostriatal dopaminergic neurotransmission. Compared to the wealth of data on the impairment of the dopamine system, relatively limited evidence is available concerning the role of major non-dopaminergic neurotransmitter systems in PD. Therefore, we comprehensively investigated the density and distribution of neurotransmitter receptors for glutamate, GABA, acetylcholine, adrenaline, serotonin, dopamine and adenosine in brains of homozygous aphakia mice being characterized by mutations affecting the Pitx3 gene. This genetic model exhibits crucial hallmarks of PD on the ne…

Histamine and serotonin released from the rat perfused heart by compound 48/80 or by allergen challenge influence noradrenaline or acetylcholine exoc…

1994

Terminal nerve fibres of the autonomic nervous system closely approach mast cells in peripheral organs, and mutual influences between release of neurotransmitters or mast cell mediators may cause neuro-immunological interactions. We have studied the influence of mast cell degranulation on the release of endogenous noradrenaline and newly incorporated acetylcholine (such as 14C-choline/acetylcholine overflow) evoked by stimulation of extrinsic postganglionic sympathetic or preganglionic vagal nerves in the rat Langendorff heart perfused with Tyrode solution. Compound 48/80 perfused in normal hearts, or ovalbumin infused into hearts from rats sensitized to ovalbumin, enhanced the overflow of …

Amplifying effect of serotonin on contractile responses in rat aorta and depletion of intracellular Ca-stores

1993

1. Serotonin, 1 microM, induces a contractile response in isolated rat aorta in the presence or absence of extracellular Ca. 2. In Ca-free media, the fast phasic contraction is lower in magnitude and further addition of serotonin evokes no response. 3. Recovery of the contractile response in Ca-free medium is obtained by a 40 min incubation in Ca-containing solution. 4. In Ca, Mg-free medium, the response to serotonin is significantly higher than that obtained in the presence of Mg. 5. An amplifying effect of serotonin on the contractile responses induced by serotonin itself or by noradrenaline was observed in Ca-containing but not in Ca-free solution.

Liraglutide and Renal Outcomes in Type 2 Diabetes.

2017

BACKGROUND: In a randomized, controlled trial that compared liraglutide, a glucagon-like peptide 1 analogue, with placebo in patients with type 2 diabetes and high cardiovascular risk who were receiving usual care, we found that liraglutide resulted in lower risks of the primary end point (nonfatal myocardial infarction, nonfatal stroke, or death from cardiovascular causes) and death. However, the long-term effects of liraglutide on renal outcomes in patients with type 2 diabetes are unknown. METHODS: We report the prespecified secondary renal outcomes of that randomized, controlled trial in which patients were assigned to receive liraglutide or placebo. The secondary renal outcome was a co…
