“We report the use of anastrozole and bicalutamide in a 5 year-old boy with familial male-limited precocious puberty. Clinical response showed decreased advancement of skeletal maturation, secondary sexual characteristics and aggressiveness with no short-term side effects. The combination seems a better option until long-term data are available.”
“A 53-year-old man presented with a 6-month history of intermittent right flank pain. Radiological imaging confirmed the diagnosis of retrocaval ureter (RCU) and ureteral calculus. Retroperitoneal laparoendoscopic

single-site Selleckchem CX-6258 surgery (LESS) ureterolithotomy and ureteroureterostomy was successfully performed. The operative time was 185 min and the blood loss was approximately 20 ml. The patient’s postoperative course was uneventful. Postoperative analgesia was not needed. The patient was discharged on the third postoperative day. The drain and double-J stent were respectively removed at 1 and 8 weeks postoperatively. At the 3-month follow-up,

nuclear scan showed no evidence of obstruction of the right kidney and the patient also remained symptom free. It may be concluded that retroperitoneal LESS Selleck BVD-523 repair for RCU is a feasible and safe procedure, which can be considered as a option for the management of RCU even if it is complicated by the presence of a ureteral calculus.”
“In recent years, there has been increased interest I-BET-762 manufacturer in biodegradable polyurethanes for use in regenerative medicine because of their versatility and biocompatibility. Nevertheless, these polymers are usually produced using organic solvents that can lead to the release of toxic components. In this work, polyurethane/montmorillonite nanocomposites were designed to work as guided tissue regeneration membranes to treat periodontal diseases. Polyurethanes were synthesized in an aqueous environment. The composition, morphology, and mechanical properties of the biomaterials were evaluated. The cellular viability,

proliferation, and morphology changes of rat culture cementoblasts were also investigated using a montmorillonite assay. Small-angle X-ray scattering, X-ray diffraction, and infrared spectroscopy results showed that the degree of clay delamination within the polymer was able to tailor the phase morphology of the polymer, the chemical aspects of the surface, the mechanical properties, and the kinetics of hydrolysis of the materials. The produced scaffolds provided a good environment for the adhesion and proliferation of cementoblasts and thus can be considered suitable biomaterials for participating in procedures associated with periodontal regeneration.
