Fungus balls as a cause of upper urinary tract obstruction are rare, with less than 60 cases reported in the literature. We herein describe three cases pf secondary anuria caused byCandida infection of the upper urinary tract. The first case was observed in a patient with a transplanted kidney, the second in a diabetic patient and the third in a patient suffering from chronic kidney failure. The treatment consisted of urinary drainage, identification of the infectious organism and appropriate antifungal treatment. 相似文献

Nanoparticles (NPs) are new inspiring clinical targets that have emerged from persistent efforts with unique properties and diverse applications. However, the main methods currently utilized in their production are not environmentally friendly. With the aim of promoting a green approach for the synthesis of NPs, this review describes eco-friendly methods for the preparation of biogenic NPs and the known mechanisms for their biosynthesis. Natural plant extracts contain many different secondary metabolites and biomolecules, including flavonoids, alkaloids, terpenoids, phenolic compounds and enzymes. Secondary metabolites can enable the reduction of metal ions to NPs in eco-friendly one-step synthetic processes. Moreover, the green synthesis of NPs using plant extracts often obviates the need for stabilizing and capping agents and yields biologically active shape- and size-dependent products. Herein, we review the formation of metallic NPs induced by natural extracts and list the plant extracts used in the synthesis of NPs. In addition, the use of bacterial and fungal extracts in the synthesis of NPs is highlighted, and the parameters that influence the rate of particle production, size, and morphology are discussed. Finally, the importance and uniqueness of NP-based products are illustrated, and their commercial applications in various fields are briefly featured.Nanoparticles (NPs) are new inspiring clinical targets that have emerged from persistent efforts with unique properties and diverse applications. 相似文献

The incorporation of tungsten trioxide (WO3) by various concentrations of graphitic carbon nitride (g-C3N4) was successfully studied. X-ray diffraction (XRD), Scanning Electron Microscope (SEM), and Diffused Reflectance UV-Vis techniques were applied to investigate morphological and microstructure analysis, diffused reflectance optical properties, and photocatalysis measurements of WO3/g-C3N4 photocatalyst composite organic compounds. The photocatalytic activity of incorporating WO3 into g-C3N4 composite organic compounds was evaluated by the photodegradation of both Methylene Blue (MB) dye and phenol under visible-light irradiation. Due to the high purity of the studied heterojunction composite series, no observed diffraction peaks appeared when incorporating WO3 into g-C3N4 composite organic compounds. The particle size of the prepared composite organic compound photocatalysts revealed no evident influence through the increase in WO3 atoms from the SEM characteristic. The direct and indirect bandgap were recorded for different mole ratios of WO3/g-C3N4, and indicated no apparent impact on bandgap energy with increasing WO3 content in the composite photocatalyst. The composite photocatalysts’ properties better understand their photocatalytic activity degradations. The pseudo-first-order reaction constants (K) can be calculated by examining the kinetic photocatalytic activity. 相似文献

Auricular fibrillation is the most common sustained cardiac arrhythmia, yet the optimal strategy for its management remains unclear. Since the study AFFIRM from which resulted them final were deferred in December 2002, the assumption of responsibility of the fibrillation of the old subject tends to become clarified. 86 patients at least 65 years or more were enrolled in our retrospective study from January 1997 to June 2003. The mean age is 70 years (65 to 82 years) and sex ratio to 0.79. 34% had a history of hypertension and 12% had a coronary artery disease. 2 groups were individualized, according to the year of admission before or after 2002. It comes out from these work 2 points: the restoration of the sinusal rhythm was the first choice. In the event of failure, the option was to maintain fibrillation and this, in the 2 groups. The AVK were founded in the large majority of the cases only after year 2002. 相似文献

Desmoplastic small round cell tumor (DSRCT) correspond to a recent clinicopathological entity, individualized in 1989 into the group of tumors with small round cells. This pathology puts ethiopathogenic, diagnostic, therapeutic and prognosis problems. Indeed, the ethiopathogenic is still unknown, diagnosis is asserted only by immuno-histochimic and cytogenetic study because of the big number of differential diagnoses and the anatomopathologic polymorphism. Its treatment is not well codified and its outcome remains dark in spite of therapeutic progress. The objective of this work is to report a personal observation of a DSRCT and to proceed to a review of the literature to clarify the epidemiological, clinical, paraclinical and therapeutic aspects of this rare tumor. 相似文献

Sweet's syndrome or acute febrile neutrophilic dermatosis is relatively frequent. It can be isolated or associated to other diseases, particularly, inflammatory or autoimmune diseases, lymphoproliferative or malignant disorders. In this retrospective study, we report 10 cases of Sweet's syndrome recorded over a 42 months period. The female predominance was net (9 womens for 1 man). The mean age was 45 years. The diagnosis was established, in all cases, on clinical, biological and histological criteria. The lesions occurred most commonly on legs (9 cases). The failure of antibiotics has been noted in all patients, and colchicine has been demonstrated efficient in 6 patients. Our study confirms the interest of cutaneous biopsy in case of papulo-nodular lesions which has not respond to antibiotics. 相似文献

Eosinophilic cystitis is a rare and uncommon inflammatory bladder disease, in which the pathophysiology is unclear; only a few cases of such disease induced by intravesical instillations have been described. We report a case of eosinophilic cystitis after intravesical bacillus Calmette-Guerin (BCG) instillation for nonmuscle-invasive transitional cell carcinoma of the bladder. To our knowledge, this report is the first case of eosinophilic cystitis induced by intravesical BCG therapy. 相似文献
