Electrochemical detection and screening of bladder cancer recurrence using direct electrochemical analysis of urine: A non-invasive tool for diagnosis

2018

Although detection of urothelial cell carcinoma (or bladder cancer, BC) can be performed via cytological, molecular and genetic marker tests on urine, cystoscopy, an invasive technique, still remains as the gold methodology in clinical practice. It is presented a non-invasive method for detecting BC recurrence consisting of a direct electrochemical test in urine combining voltammetric data at gold and glassy carbon electrodes. The diagnosis is based on the ratio between characteristic voltammetric features recorded for tryptophan, serotonin and melatonin and other related metabolites. The method was tested by means of a clinical trial with 30 patients diagnosed of bladder cancer and a two c…

Gas-containing renal stones: a red flag for renal infection.

2022

Background Gas in the renal excretory system is described as a consequence of recent procedures but it can be a sign of severe conditions such as fistulas or infections; however, gas-containing renal stones are only rarely encountered. Purpose To describe the association of gas-containing renal stones and urinary tract infection. Material and Methods We performed a retrospective evaluation of the clinical and imaging findings in a series of six patients with gas-containing renal stones and compared our findings with those of patients with gas-containing renal stones reported in the literature. Urine and stone cultures were used as a diagnostic standard for urinary tract infection. Results I…

Thrombotic thrombocytopenic purpura (TTP) leading to pseudotumour's autoimmune pancreatitis (AIP): A case report

2012

International audience; Introduction: Autoimmune pancreatitis is an idiopathic inflammatory disease that produces pancreatic masses and ductal strictures. This benign disease can be associated with extrapancreatic manifestations including cholangitis, sialadenitis, inflammatory bowel disease or retroperitoneal fibrosis, mediastinal adenopathy, interstitial nephritis mainly due to immunoglobulin G4 (Ig G4), and occasional association with other auto-immune diseases. Observation: We report a 57-year-old woman who developed thrombotic thrombocytopenic purpura (UP) and pseudo-tumour's seronegative autoimmune pancreatitis (ATP) type 1. The patient was initially treated with pulse corticosteroids…

Antiketogene Wirkung von Xylit bei alloxandiabetischen Ratten

THERAPEUTIC AND COLATERAL EFFECTS OF 25-HYDRXYCHOLECAICI FEROL IN VITAMIN D DEFICIENCY

1974

Vitamin D polar metabolite, 25–HCC has been used in 2 infant groups whose ages range from 0–18 months. In the 1st group of 15 infants, all of them suffered from rickets, clinically, biochemistry and radiologically and no prophylactic vitamin D administration could be demonstrated. The control group (15 infants too) was admitted with similar diseases but no one suffered from rickets. Routine determinations for metabolic assesment of Ca phosphoric metabolism were perforaed in plasma and in 240. urine collections, prior and after 25–HCC adBinietration. The rickets group received 20 mcg/day, orally for 20 days and the control 10mcg/day in the same way. The biochemical study demonstrated that bo…

Kinder und Jugendliche mit neurogener Blasenfunktionsst�rung

2004

After the failure of conservative treatment in patients with neurogenic bladders, urinary diversion is a viable compromise between the urologist's concerns and the patient's desire, as the upper urinary tract can be protected in the long-term and high continence rates can be provided. This can be achieved with an acceptable complication rate. Our indications for orthotopic bladder augmentation or substitution involve patients with a good orthopedic condition and mobility, who find it easy to perform CISC through the urethra. A continent umbilical stoma offers a good alternative in obese, immobile or wheelchair bound patients. The serous lined extramural tunnel technique has proven to be sup…

Single Intravenous Dose Kinetics and Accumulation of Atenolol in Patients with Impaired Renal Function and on Hemodialysis

1980

The concentration of atenolol in plasma and urine was determined following an intravenous (i.v.) dose given to 17 hypertensive patients with a glomerular filtration rate (GFR) between 5 and 105 ml/min and in 4 patients on hemodialysis. In patients with normal renal function the mean half life of elimination was calculated to be 6.8 h. This value increased to a mean of 50.1 h in patients with a GFR below 10 ml/min. In patients on hemodialysis the half life of elimination was about 4 h. The elimination rate constants as well as the body and renal clearances of atenolol have a significant correlation with the GFR. Although accumulation of atenolol was observed, especially after multiple oral d…

Cigarette smoke-induced pulmonary endothelial dysfunction is partially suppressed by sildenafil.

2009

Abstract Cigarette smoke mediated oxidative stress and endothelial dysfunction are important processes in the pathogenesis of several lung disorders. In this study we evaluated the effect of PDE5 inhibition on pulmonary artery endothelial dysfunction induced by cigarette smoke in vitro . Human pulmonary artery endothelial cells (HPAEC) were incubated in the absence or presence of PDE5 inhibitor sildenafil (10 nM–1 μM), PKG agonist 8-Br-cGMP (1 mM), or the antioxidants dyphenyleneiodonium (DPI 1 μM) and N -acetylcysteine (NAC 1 mM) for 30 min. Then, cigarette smoke extract (CSE) was added for 24 h. CSE (2.5–10%)-induced ROS generation was suppressed by DPI, and partially reversed by sildenaf…

Muscle cramping in the marathon: dehydration and electrolyte depletion vs. muscle damage

2020

Martinez-Navarro, I, Montoya-Vieco, A, Collado, E, Hernando, B, Panizo, N, and Hernando, C. Muscle Cramping in the marathon: Dehydration and electrolyte depletion vs. muscle damage. J Strength Cond Res XX(X): 000-000, 2020-Our aim was to compare dehydration variables, serum electrolytes, and muscle damage serum markers between runners who suffered exercise-associated muscle cramps (EAMC) and runners who did not suffer EAMC in a road marathon. We were also interested in analyzing race pacing and training background. Nighty-eight marathoners took part in the study. Subjects were subjected to a cardiopulmonary exercise test. Before and after the race, blood and urine samples were collected and…
