Some amphibians occur in agricultural landscapes during certain periods of their life cycle and consequently might be exposed to plant protection products (PPPs). While the sensitivity of aquatic life-stages is considered to be covered by the standard assessment for aquatic organisms (especially fish), the situation is less clear for terrestrial amphibian life-stages. In this paper, considerations are presented on how a risk assessment for PPPs and terrestrial life-stages of amphibians could be conducted. It discusses available information concerning the toxicity of PPPs to terrestrial amphibians, and their potential exposure to PPPs in consideration of aspects of amphibian biology...

OBJECTIFS: L'insuffisance rénale chronique (IRC) se définit comme une diminution prolongée et souvent définitive des fonctions exocrines et endocrines du rein. Cette maladie est évolutive, et lorsqu'elle atteint un stade terminal, elle est incompatible avec la vie. Afin d'évaluer cliniquement les troubles phosphocalciques, notre travail est mené chez les patients atteints d'IRC de l'ouest d'Algérie (Oran, Mostaganem, Ain Témouchent,…). Notre étude a porté sur 62 malades insuffisants rénaux chroniques...

This is a report of chromophobe renal cell carcinoma (ChRCC), a rare entity that accounts for 6% to 11% of cases of renal cell carcinoma (RCC). ChRCC is considered to yield a good prognosis as it typically presents as an early stage tumor with longer overall survival when compared with clear cell RCC; however, metastatic disease negates this survival difference and is characterized by poor prognosis. The available clinical investigations supporting the guidelines for treatment of metastatic RCC are predominantly based on clear cell RCC studies...

After a series of outbreaks associated with sprouts in the mid-1990s, the U.S. Food and Drug Administration (FDA) published guidelines in 1999 for sprouts producers to reduce the risk of contamination. The recommendations included treating seeds with an antimicrobial agent such as calcium hypochlorite solution and testing spent irrigation water for pathogens. From 1998 through 2010, 33 outbreaks from seed and bean sprouts were documented in the United States, affecting 1330 reported persons. Twenty-eight outbreaks were caused by Salmonella, four by Shiga toxin-producing Escherichia coli, and one by Listeria...

Tubulocystic renal cell carcinoma (TRCC) is an indolent type of renal cell carcinoma with a good prognosis based on the limited number of published cases. Herein, we describe the unusual clinical, pathologic and molecular findings in a case of TRCC. Our patient with TRCC had two local recurrences and a brain metastasis following radical nephrectomy. Unusual histologic findings included focal solid growth pattern and cytologic atypia. A genome-wide molecular inversion probe assay identified copy number (CN) loss in three chromosome regions and one region with copy-neutral loss of heterozygosity (copy-neutral LOH)...

OBJECTIVES: Bladder perforation is the second most common complication during transurethral resection of bladder tumours. It is unknown whether perforation affects the natural history of the tumour through cell seeding. The aim of this study was to study the impact of perforation on the oncologic outcomes of bladder carcinoma. MATERIALS AND METHODS: Between 2003 and 2007, 926 consecutive patients underwent transurethral resection of bladder tumours at our institution; 327 cases were staged ≥ pT2 and were treated immediately with cystectomy and/or multimodal therapy and therefore excluded from the study...

PURPOSE: Prostate cancer treatment results in several sexually related side effects beyond the well studied erectile dysfunction. Climacturia (leakage of urine during orgasm) has been reported after prostatectomy but studies have been limited by multiple factors. In this study we examine the prevalence, causes and impact on orgasm function of climacturia after definitive treatment of prostate cancer with surgery or radiation. MATERIALS AND METHODS: A total of 906 anonymous surveys were sent to patients with prostate cancer treated with surgery and/or radiation...

BACKGROUND: Benign prostate syndrome (BPS) is a common phenomenon in the aging male. Transurethral resection of the prostate (TURP) remains the international standard of care for -patients requiring surgical intervention for BPS. Although the voiding improvement following TURP is well-documented, controversy exists regarding its effect on post-operative sexual function. In this study we investigated the possible influence of individual surgeons on clinical voiding parameters and post-operative sexual function after TURP...
