Xanthogranulomatous pyelonephritis: presentation and management

Xanthogranulomatous pyelonephritis (XGP) is characterized by the presence of lipid-laden foamy macrophages with both acute and chronic phase inflammatory cells. The aim of the study is to present our experience about patients with Xanthogranulomatous pyelonephritis. 29 patients were evaluated through a complete anamnesis and the preoperative management included routine blood and biochemical tests, urine culture and renal ultrasound, intravenous urography and computed tomography (CT). All patients underwent open nephrectomy followed by the pathological exam. The main symptoms of these patients were fever and flank pain. Preoperative laboratory tests revealed anemia, leukocytosis and increasing levels of blood urea nitrogen (BUN) and creatinine. Kidney failure was noticed in almost half of the cases. This study succeeded to evaluate the demographic, clinical, biological, surgical and histological characteristics. A pathological diagnosis is mandatory mainly for the evaluation of its coexistence with renal carcinoma

In vitro evaluation of probiotic properties of A lactic acid bacteria isolated from piglet

The aim of this study was to evaluate the probiotic aspects of lactic acid bacteria (LAB) isolated from faeces of a healthy piglet (30-d-old, Topigs). Cultural, morphological and biochemical characteristics by standard API 50 CHL Biomerieux strips of isolated strain was assayed as well. The strain was conserved as Lactobacillus fermentum 1 IBNA 95 and can be found in the collection of INCDBNA. It is a Gram positive, non-spore forming, aerotolerant bacteria. It appears isolated and grew at 37°C in Oxoid MRS broth and MRS agar medium. The functional properties tested were to survive at pH 3.0 and to present resistance at addition of 0.3% bile salts (w/v). The strain was able to survive at a low pH value and to tolerate 0.3% bile salt solution during 3h exposure under according simulated gastrointestinal condition. Lactobacillus fermentum 1 IBNA 95 was presenting some probiotic features, thus can be a promising feed supplement for piglet’s nutrition
