OBJECTIVE To measure length of hospital stay (LHS) in patients receiving medication reconciliation. Secondary characteristics included analysis of number of preadmission medications, medications prescribed at admission, number of discrepancies, and pharmacists interventions done and accepted by the attending physician. METHODS A 6 month, randomized,(More)
Antithyroid drugs sometimes cause severe complications. Propylthiouracil (PTU) can be associated to ANCA positive vasculitis, most often related to myeloperoxidase subtype (ANCA-MPO). Our objective is to describe a female patient with Graves' disease, who developed PTU induced-autoimmune disease, with cutaneous, pulmonary, and renal lesions, associated with(More)
Diabetes mellitus, especially when not under control, can lead to several neurological complications being the development of involuntary movements one of the rarest presentations. Nonketotic hyperglycemia in aged patients who present with ballismus-chorea movements and cerebral image alterations in computerized tomography (CT) and magnetic resonance(More)
Fungal urinary tract infections are an increasing problem in hospitalized patients. Funguria may be a result of contamination of the urine specimen, colonization of hte urinary tract, or may be indicative of true invasive infection. In this study, we report the risk factors, clinical features, treatments and outcome in a group of 68 hospitalized patients(More)
PURPOSE To study the changes in calcium oxalate crystal morphology induced by different levels of supersaturation (SS) in human urine. MATERIALS AND METHODS Twenty-four hours urine samples from 5 normal men were collected. Each specimen was centrifuged and filtered. About 200 mL of each sample was dialyzed overnight. Aliquots of 2 mL of urine was then(More)
One of the defenses against nephrolithiasis is provided by macromolecules that modulate the nucleation, growth, aggregation and retention of crystals in the kidneys. The aim of the present study was to determine the behavior of two of these proteins, Tamm-Horsfall and uromodulin, in calcium oxalate crystallization in vitro. We studied a group of 10 male(More)
OBJECTIVES To study the role of urinary inhibitors on crystallization-nephrocalcin, Tamm-Horsfall protein (THP), and glycosaminoglycans (GAGs)-in hyperuricosuric nephrolithiasis using Dalmatian dogs, a breed well-known for high levels of uric acid excretion, in an in vivo model. METHODS Urine samples were collected from 10 stone-forming Dalmatian dogs and(More)
Objective. To profile a sample of gouty patients treated with allopurinol, benzbromarone, or a combination of these two drugs and to describe the impact of this therapy in reducing uric acid levels. Methods. An observational, transversal study was performed. We evaluated 48 patients diagnosed with gout who were seen at the Outpatient Rheumatology Clinic of(More)
