The effects of vitamin A deficiency on urolithiasis were investigated in male rats. A vitamin A-deficient diet caused important changes in the composition of the urine of the treated rats when compared with controls. One of the main effects was a decrease in the concentration of urinary glycosaminoglycans and zinc in the rats receiving the vitamin(More)
The effects of phytic acid and phytic acid/zinc mixtures on renal urolith development in an animal model of nephrolitiasis were studied. Male rats were divided into four groups of 15, 10, 10 and 12 rats each. The rats of Group I were treated with ethylene glycol; of Group II with ethylene glycol plus zinc; of Group III with ethylene glycol phytic acid; and(More)
Myo-inositol hexaphosphate (InsP6) is an abundant component of plant seeds. It is also found in significant levels in blood and mammalian tissues, but they are totally dependent on their dietary intake. In the present paper, we describe studies on the effect of InsP6 on a model of dystrophic calcification, which was chemically induced by subcutaneous(More)
PURPOSE In the procedure of sinus floor elevation, autogenous bone, allogenic grafts, and several other bone substitutes are used. However, autogenous bone is still considered the gold standard. Donor sites for autogenous bone are generally the iliac crest, oral cavity, calvarium bone, and tibia. In this work the experience with the use of a Safescraper(More)
The increase in the number of solid organ transplants has resulted in an increased incidence of opportunistic infections, including infection by typical and atypical mycobacteria, with risk of developing tuberculosis. Pretransplant chemoprophylaxis with isoniazid has become increasingly common in an attempt to prevent the disease. The source of infection in(More)
Infection by intracellular microorganisms with a special geographic distribution, such as Leishmania spp, has been reported in a limited number of patients undergoing solid-organ transplant (SOT). No cases of Leishmania spp infection in lung transplant patients were found in a review of the literature. In our series of 222 lung or heart and lung(More)
Lung transplantation is an established procedure to treat patients with end-stage lung disease. The criteria for recipient selection are broadening to include patients with congenital defects of the immune system, such as X-linked hypogammaglobulinemia (XLA). We report 2 cases of successful double lung transplantation in patients with XLA. The 2 men had(More)
PURPOSE Müller muscle-conjunctiva resection could be seen as a relative contraindication in patients with a prior history of a glaucoma filtering procedure, corneal disease, or corneal surgery. The concern centers around the theoretical risk of bleb-related complications or corneal damage from the palpebral conjunctival sutures. Our study aimed to determine(More)
We present the case of a 68-year-old man who presented dysphagia and weight loss over the previous three months. Esophageal transit showed extreme stenosis suspicious for neoplasia but which was revealed to be a granulomatous inflammatory lesion. Culture of the lesion revealed Mycobacterium tuberculosis. Chest x-ray showed pulmonary tuberculosis. Esophageal(More)
Lymphoproliferative syndromes are the most common tumors in transplant recipients. More than 90% of posttransplantation lymphoproliferative syndromes (PTLS) are considered to be associated with Epstein-Barr virus, and 86% are of the B-cell line. Histopathology ranges from polymorphic-reactive to monomorphic forms. Clonality should be studied using molecular(More)
