Risk factors for high fall risk in elderly patients with chronic kidney disease
2022
Purpose: Patients with chronic kidney disease (CKD) usually represent an aging population, and both older age and CKD are associated with a higher risk of falling. Studies on risk factors among subjects with CKD are lacking. Methods: Records of outpatients from one geriatric clinic in Turkey were retrospectively reviewed. A result of ≥ 13.5 s on the timed up and go (TUG) test was accepted as a high risk of falls. Independent predictors of an increased risk of falls among subjects with CKD (estimated glomerular filtration rate of < 60 mL/min/1.73 m2) were identified using logistic regression models. Results: Patients with CKD (n = 205), represented the 20.2% of the entire cohort and was i…
Kinetics of serum total and free prostate-specific antigen (PSA) after extended multisite prostate biopsy: Comparison among biopsy, transurethral res…
2008
Abstract Background The kinetics and reproducibility of serum prostate-specific antigen (PSA) following extended multisite biopsies are unknown. The aim of this study was to examine the kinetics of hematogenous leakage of PSA molecules by comparing the postintervention PSA manner among extended biopsies, transurethral resection of the prostate (TURP) and biopsy plus TURP. Methods Total and free PSA values were examined before and sequentially after intervention (at 1 hour, 24 hours, 2 days, 14 days, and 28 days), in patients who underwent 14-core prostate biopsy (Biopsy, n = 53), TURP (TURP, n = 21), or prostate biopsy plus TURP (Biopsy+TURP, n = 18). Results Ten patients in the Biopsy grou…
Usefulness of microalbuminuria in cardiovascular risk stratification of essential hypertensive patients
2004
<i>Background/Aims:</i> To evaluate the influence of microalbuminuria (albumin excretion rate – AER) determination and echocardiography (ECHO) on cardiovascular risk stratification, initially performed according the 1999 WHO/ISH guidelines by using only routine diagnostic procedures with or without fundal examination. <i>Methods:</i> 312 essential hypertensives attending our institution were studied retrospectively. Cardiovascular risk was assessed in a semiquantitative way using four categories of absolute cardiovascular disease risk (low, medium, high and very high risk), as proposed by the 1999 WHO/ISH guidelines, on the basis of data on the average 10-year risk o…
Rectosigmoid Pouch (Mainz Pouch II) in Children
2005
Continent anal urinary diversion is a therapeutic option in bladder exstrophy. We report our long-term results with the rectosigmoid pouch (Mainz pouch II), a modification of the classic ureterosigmoidostomy.A total of 38 children with a mean age of 5 years (range 0.5 to 17) underwent a Mainz pouch II procedure between 1991 and 2004. Most patients (33) had bladder exstrophy or incontinent epispadias. In 14 children (37%) urinary diversion was performed after failed primary reconstruction. In 6 children conversion was performed from an incontinent type of urinary diversion. Renal function, continence and metabolic changes were analyzed. A total of 35 children were followed for a mean of 112 …
How radical prostatectomy procedures have changed over the last 10 years in Italy: a comparative analysis based on more than 1500 patients participat…
2020
Purpose Therapeutic strategies for prostate cancer (PCa) have been evolving dramatically worldwide. The current article reports on the evolution of surgical management strategies for PCa in Italy. Methods The data from two independent Italian multicenter projects, the MIRROR-SIU/LUNA (started in 2007, holding data of 890 patients) and the Pros-IT-CNR project (started in 2014, with data of 692 patients), were compared. Differences in patients' characteristics were evaluated. Multivariable logistic regression models were used to identify characteristics associated with robot-assisted (RA) procedure, nerve sparing (NS) approach, and lymph node dissection (LND). Results The two cohorts did not …
Long-term outcome of ventral buccal mucosa onlay graft urethroplasty for urethral stricture repair
2004
Abstract Objectives To evaluate our patients who were treated with ventral buccal mucosa onlay grafts for open urethral stricture repair with a follow-up exceeding 5 years. Buccal mucosa onlay is widely used for urethral reconstruction; however, the long-term outcome of these patients remains unclear. Methods During the past 10 years, 67 patients underwent ventral buccal mucosa onlay graft surgery for urethral stricture repair. Of these, 32 were followed up for longer than 5 years (mean 6.9 years) for the occurrence and timing of any postoperative complications. All patients had undergone prior internal urethrotomy (mean 2.9 procedures), and the average length of the stricture was 4.3 cm (r…
Incidence, Clinical Symptoms and Management of Rectourethral Fistulas After Radical Prostatectomy
2009
Rectourethral fistula is a rare but severe complication after radical prostatectomy and there is no standardized treatment. We retrospectively evaluated the incidence, symptoms and management of rectourethral fistulas based on our experience.From 1999 to 2008 we performed 2,447 radical prostatectomies. Patients in whom postoperative rectourethral fistulas developed were identified. Based on the therapeutic approach patients were categorized into group 1-conservative treatment, group 2-colostomy with or without surgical closure and group 3-immediate surgical closure without colostomy.Rectourethral fistulas developed in 13 of 2,447 patients (0.53%) after radical prostatectomy. The risk of rec…
Influence of Ketamine anaesthesia on renal and cardiovascular functions in mongrel dogs
1979
Cardiac minute volume, renal blood flow, pulse volume, heart rate and urinary output were determined by means of experiments made on 10 mongrel dogs. Anaesthesia was maintained by nitrous oxide/oxygen mixture administered with Ketamine. Under the conditions described it was observed that -- contrary to what is found in human patients -- cardiac and renal minute volume as well as pulse volume are significantly decreased. No significant changes has been observed in the heart rate. Whilst urinary output was decreased, the excretion of individual electrolytes was found to be different.
IgE in patients with glomerulonephritis and minimal-change nephrotic syndrome
1979
Serum levels of IgE were studied in 30 children with minimal-change nephrotic syndrome and 32 children with mesangioproliferative glomerulonephritis during different stages of the disease and treatment. In addition, tissue obtained by renal biopsy was investigated by immunofluorescence histology; no deposits of IgE could be found. The serum IgE levels, however, were increased, particularly in patients with minimal-change nephrotic syndrome. It is concluded that IgE does not play a pathogenic role in the development of the renal disease, but that increased IgE levels are an indication of a disturbance of the immune system.
Nicotinic drugs and postganglionic sympathetic transmission
1970
1. Isolated rabbit hearts with the sympathetic nerves attached were perfused with Tyrode solution. The noradrenaline output into the perfusate was measured fluorimetrioally. 2. When the niootinic autoinhibition produced by infusions of nicotine, DMPP, or acetylcholine (in the presence of atropine) was fully developed, the output of noradrenaline evoked by electrical stimulation of the postganglionic sympathetic nerves was not depressed. 3. Acetylcholine in the presence of atropine produced a transitory facilitation of the noradrenaline output evoked by sympathetic nerve stimulation. 4. Prolonged infusion of DMPP caused an adrenergic neurone block which was not observed after nicotine, or ac…
