Sommario/riassunto

Simulation models are an established method used to investigate processes and solve practical problems in a wide variety of disciplines. Central to the concept of this second edition is the idea that environmental systems are complex, open systems. The authors present the diversity of approaches to dealing with environmental complexity and then encourage readers to make comparisons between these approaches and between different disciplines.  Environmental Modelling: Finding Simplicity in Complexity 2nd edition is divided into four main sections: An overview

Sommario/riassunto

Most men with BPH can be diagnosed and managed in the primary care setting. In choosing appropriate treatment, clinicians must take into account not only the nature and severity of symptoms but also the preferences of the patient and his immediate family, cost–benefit considerations and long-term effectiveness of therapy.    Written by two leading urologists, 'Fast Facts: Benign Prostatic Hyperplasia' provides a refreshingly readable, practical overview of the pathophysiology, diagnosis and treatment of BPH including:    • Use of DRE and PSA results to discriminate between prostate cancer and BPH  • An evidence-based review of the latest medical therapies  • A concise overview of the surgical and minimally invasive treatment options  • When to refer to a urologist    There is important work to do to raise awareness of men’s health issues in general and the problem of BPH in particular. Lower urinary tract symptoms are among the commonest reasons for a man to consult his doctor, and this ever-popular book – the first 7th edition in the Fast Facts series – remains a must-read for all primary care providers.    Contents:    • Pathophysiology  • Diagnosis  • Medical management  • Traditional surgical treatment options  • Minimally invasive treatment options  • Considerations in treatment decisions  • Issues in BPH  • Useful resources
