Blood levels of homocysteine, cysteine, glutathione, folic acid, and vitamin B12 in the acute phase of atherothrombotic stroke.
2009
Blood levels of total homocysteine (tHcy), cysteine (Cys), total and reduced glutathione (tGSH and rGSH), folic acid (FA), and vitamin B(12) (B(12) change during ischemic stroke as accompaniment of the tissue damage. The relationship between these changes remains scantly investigated. We evaluated the variation of these molecules in the 48 h after acute large artery atherothrombotic stroke (LAAS) and searched for the presence of matched variation of them. The study involved 50 subjects affected by acute LAAS and 49 healthy controls. Plasma levels of tHcy and Cys were significantly higher and serum levels of FA and B(12) and plasma levels of rGSH were significantly lower in the patients than…
Endoluminal sclerosis with diode laser in the treatment of orofacial venous malformations
2012
Introduction: The appearance of vascular anomalies in the orofacial area is a common condition, which represents about 50% of these malformations. Traditional treatment approach, such as surgery and chemical sclerosis has been given way to a few less-invasive options, as the use of the 810nm diode laser to induce the sclerosis of the venous malformation by intralesional photocoagulation. Objectives: The objective of this study was to determine the efficacy of the diode laser in the intralesional treatment of the orofacial venous malformations (OFVM), describing the recommended surgical approach, as well as to report the main associated complications. Patients and Methods: 10 cases of OFVM, …
How to Name Papillary Tumors of the Bladder in Children: Transitional Cell Carcinoma or Papillary Urothelial Neoplasm of Low Malignant Potential?
2015
Urinary bladder malignancies are uncommon in children. Approximately 80 children with papillary carcinoma have been described to date, presenting as papillary neoplasms of both low grade and low stage. On the basis of the 1973 World Health Organization classification, tumors were classified as transitional cell carcinoma of the urinary bladder (TCCB). Owing to more detailed histologic criteria, this term has been replaced by papillary urothelial neoplasm of low malignant potential and low-grade carcinoma of the urinary bladder in the World Health Organization-International Society of Urologic Pathology consensus classification system of urothelial neoplasms 2004. Nevertheless, TCCB still re…
Factor V Leiden and prothrombin gene mutation in inflammatory bowel disease in a Mediterranean area.
2001
Abstract Background. Thromboembolism has been reported to be associated with inflammatory bowel disease. Aim. To evaluate the association of factor V Leiden and prothrombin gene mutation with inflammatory bowel disease in a population of patients with thromboembolic events and inflammatory bowel disease and in a control population of patients with inflammatory bowel disease without thromboembolic events. Patients and methods. A series of 18 patients with inflammatory bowel disease and a history of arterial or venous thrombosis and 45 patients with inflammatory bowel disease without thromboembolic events were evaluated for the presence of factor V Leiden and prothrombin gene mutation. Freque…
Effectiveness of platinum wire microcoils for venous occlusion: A study on patients treated for venogenic impotence
1994
The purpose of this study was to determine the effectiveness of venous occlusions achieved by embolization with platinum microwire coils. Follow-up venographies in 19 patients, 1-20 months (average 8 months) after coil embolizations, were evaluated. Twenty-eight of 126 (22.2%) coil embolizations were found to be patent. Coils which had not formed or partially formed upon embolization had a patency/recanalization rate of 37.5% (12/32). Among coils which had formed nearly completely or completely only 16 of 95 (17%) showed venous patency. As coil embolization had been augmented by sclerotherapy in all patients, the effectiveness of long-term venous occlusion by platinum wire coils alone is pr…
Metabolic and Cardiovascular Effects of Switching Thiazides to Amlodipine in Hypertensive Patients With and Without Type 2 Diabetes (the Diuretics an…
2020
Background: Different studies have indicated that thiazide diuretics can increase the risk of developing type 2 diabetes (T2D). Therefore, in this study, we investigated whether switching from hydrochlorothiazide (HCTZ) to amlodipine resulted in ameliorating different cardiovascular and metabolic measures in hypertensive patients with or without T2D. Methods: This study [Diuretics and Diabetes Control (DiaDiC)] was a 6-week, single-blind, single-center randomized controlled trial. The first 20 normal glucose-tolerant, 20 prediabetic, and 20 T2D consecutive patients were randomized to continue the previous antihypertensive treatment with HCTZ (12.5-25 mg/day) or to switch from HCTZ to amlodi…
Effects of aquatic resistance training on mobility limitation and lower-limb impairments after knee replacement.

Objective To study the effects of aquatic resistance training on mobility, muscle power, and cross-sectional area. Design Randomized controlled trial. Setting Research laboratory and hospital rehabilitation pool. Participants Population-based sample (N=50) of eligible women and men 55 to 75 years old 4 to 18 months after unilateral knee replacement with no contraindications who were willing to participate in the trial.

Factors responsible for interindividual differences in the dose requirement of phenprocoumon
1987
The total and unbound plasma concentrations of phenprocoumon and the prothrombin complex activity were determined in 51 patients on phenprocoumon. A 7-fold difference in the dosing rate (10-70 micrograms/kg/day) was required to maintain the prothrombin complex activity at 11-30% of normal. The variation in dosing requirement was mainly due to interindividual differences in the intrinsic clearance of phenprocoumon and only to a minor degree to differences in sensitivity to it. On average patients with myocardial infarction required only 2/3 of the daily dose of phenprocoumon of post cardiac surgery patients and patients with thrombosis and emboli. That difference appeared to be due to higher…
Sex-related Differences in Disposition and Response to Phenprocoumon in Rats
1988
Abstract The pharmacokinetics and the pharmacological response to phenprocoumon have been studied in female and male inbred Lewis-Wistar rats. A significantly lower clearance was found in female than in male rats (7.9 ± 1.4 vs 24.5 ± 2.5 mL h−1 kg−1, respectively; t = 15.09, P < 0.001) as well as a lower apparent volume of distribution (288 ± 46 vs 617 ± 105 mL kg−1; t = 7.58, P < 0.001) and a longer half-life (25.5 ± 3.4 vs 17.5 ± 1.8 h; t = 5.16, P < 0.001). The binding of phenprocoumon was higher in female than in male rats (fu: 0.0096 ± 0.0008 vs 0.0124 ± 0.0007, respectively; t = 6.66, P < 0.001). The total (C) as well as the unbound concentration (Cu) neede…

2019
Patient: Male, 59 Final Diagnosis: Chromophobe renal cell carcinoma, stage IV Symptoms: Discomfort in the right hypochondrium Medication: Oncolytic virus Rigvir Clinical Procedure: Nephro-adrenalectomy Specialty: Oncology Objective: Unusual or unexpected effect of treatment Background: Renal cell carcinoma is the most commonly diagnosed primary malignant tumor of the kidney in adults, and includes the variant of chromophobe renal cell carcinoma. Despite new targeted therapies that improve progression-free survival (PFS) and overall survival (OS) for early-stage renal cell carcinoma, the 5-year survival for patients with stage IV renal cell carcinoma remains below 10%, and the 50% OS is less…
