Top Articles in Primary Care
by John Russell Neil S. SkolnikThis book reviews, in one place, the breadth of articles that form the basis for the current practice of medicine. When physicians examine medical literature, there are articles that are quoted over and over again, as well as articles that have established the standards that are so embedded that we no longer think of where those standards came from. When clinicians treat patients with diabetes, why do we aim for an A1c less than 7%? That standard comes primarily from two trials, the DPPT and the UKPDS trial, both of which broke new ground when they were published. In addition, the ACCORD trial informed us that a lower A1c goal does not improve outcomes, and may in fact lead to worse outcomes. Understanding these trials helps physicians to make better decisions for their patients and gives them a greater appreciation for the information they work with every day.The chapters are organized by system such as respiratory, cardiovascular, diabetes, etc. and within each system, in the chronological order of publication. Each article reviewed includes a succinct overview of methodology and the results, followed by a discussion that puts the results into clinical context. All articles are selected and chapters written by primary care physicians who understand what is relevant to the intended audience for the book. Written by experts in the field, Top Articles Every Clinician Should Know provides readers with one source where information can be found about the most important articles published in the medical literature that informs the way clinicians practice primary care today.

Top Knife: L'arte e il mestiere della chirurgia del trauma
by Asher Hirshberg Kenneth L. MattoxQuesto libro si propone di impartire i consigli utili sul modo migliore per accompagnare il paziente traumatizzato grave in sala operatoria, organizzare il lavoro tuo e dell’équipe, sudare sette camicie per risolvere una situazione difficile, ma alla fine chiudere l’intervento con il miglior risultato possibile. In poche parole, una guida pratica sulla chirurgia del trauma destinata non solo agli specializzandi e ai tirocinanti, ma anche ai chirurghi generali interessati al trattamento dei pazienti traumatizzati e ai chirurghi che operano in condizioni difficili – ad esempio presso gli ospedali militari, i distretti rurali o nell’ambito di missioni umanitarie. Sull’atlante chirurgico impari a utilizzare le mani, ma certo non a ragionare, prevenire le mosse e improvvisare, mentre grazie ai nostri consigli pratici apprenderai che quando operi un paziente traumatizzato con emorragia massiva devi usare la testa, oltre che le mani. La prima parte illustra alcuni dei principi generali della chirurgia del trauma, soffermandosi non tanto su come si dovrebbe suturare, quanto piuttosto sulla necessità di sviluppare la capacità di pensare e programmare quando si sta davanti al tavolo operatorio. Purtroppo soltanto di rado, per non dire mai, queste capacità si apprendono frequentando le scuole di specializzazione. La seconda parte è dedicata alla chirurgia del trauma vista come uno sport da contatto: insegna come si trattano specifiche lesioni a carico dell’addome, del torace, del collo e dei vasi periferici, mettendo in particolare evidenza come le cose potrebbero non andare per il verso giusto, un aspetto quasi sempre tralasciato dai testi tradizionali. L’esperienza, invece, ci ha insegnato che imparare dove sono le insidie è essenziale se si vuole imparare ad operare. La lezione più importante che ci auguriamo tu possa trarre da questa guida è di scegliere sempre la soluzione più semplice, perché nella chirurgia del trauma è l’unica che non riserva mai sorprese e dà risultati.

Top Tips for GPs: A Beginner's Guide to General Practice
by Knut SchroederFor GPs and practice managers the challenge of the NHS reforms is to understand the business context in which general practice operates. Of the many skills learned from commerce and industry needed for the development of an effective strategy, business planning has been demonstrated to bring important benefits to the practice. However, for many the concept is necessary but unfamiliar. This book sets out to demystify the subject, explains the benefits and, by way of numerous examples, shows how they can be applied to the single-handed GP and group practices, whether or not they are fundholders. It suggests that good clinical care is not possible without the necessary planning and management skills to run a business.

Topics and Perspectives in Adenosine Research: Proceedings of the 3rd International Symposium on Adenosine, Munich, June 1986
An "International Conference on Physiological and Regulatory Functions of Adenosine and Adenine Nucleotides" was held in Banff, Canada, in June 1978. Four years later, in June 1982, an "International Symposium on Adenosine" took place in Charlottesville, Virginia, USA. Both meetings revealed an increasing interest of scientists from numerous disciplines on biochemical, physiological and pathophysiological aspects of adenosine as a proposed mediator of various specified regulatory functions, both on the cellular and organ level. In view of the obvious continuity of adenosine research in well-established and newly emerging fields, a scientific committee was charged with organizing a further meeting to be held in Munich, Germany, in June 1986. Members of the committee were H. P. Baer, Canada, R. M. Berne, USA, and E. Gerlach, G. W. Kreutzberg and J. Schrader, FRG. It was the general intention that in this conference, purposely named "3rd International Symposium on Adenosine", emphasis should be placed on the presentation of shorter reports concerning both latest as well as controversial aspects and developments in as wide a scope of adenosine research as possible. Therefore, in addition to more than 50 presentations by invited speakers, over 120 posters were displayed. Coinciding with the symposium, abstracts of all contributions were published in Pfltigers Archiv - European Journal of Physiology [Vol. 407, Suppl. 1, 1986]. This book, entitled "Topics and Perspectives in Adenosine Research", now enholds all papers presented at the 3rd International Symposium on Adenosine, together with the complete discussions following each talk.
Topics in Acute and Chronic Pancreatitis: Proceedings of the International Meeting held in Padenghe sul Garda (Italy), September 14-15, 1979
by C. Banterle G. Cavallini P. Pederzoli G. P. Marzoli A. Dagradi L. A. ScuroThe increasing incidence of both chronic pancreatitis and pan creatic cancer was the primary impetus for the organization of this meeting, an additional factor being the widespread existence of pancreatic disease within Italy itself. It is well known that the treatment of chronic and particularly of acute pancreatitis is still a matter of controversy, and it seemed useful to compare our own experience with that of other centers working in the same field. Consequently, in addition to numerous Italian specialists in the field, doctors from the Federal Republic of Germany, Denmark, Great Britain, France, and Austria were invited to attend the meeting. The symposium lasted two days and comprised eight sessions dealing with the anatomy and physiology of the pancreas and the pathophysiology, diagnosis, and treatment of pancreatic diseases. A central feature of the discussion on the surgical treatment of chronic pancreatitis was the debate between those who favor the use of drainage and those who believe resection to be the best treatment. Finally, I would like to thank Dr. Cavallini and Dr. Pederzoli very much for their help in organizing the meeting and also the local authorities for their aid. Professor Adamo Dagradi Director of the Institute of Clinica Chirurgica, Verona Opening Address I am pleased to welcome all partlclpants and particularly the guests from abroad, to this meeting on the clinical evaluation of pancreatitis.

Topics in Biomedical Gerontology
by Pramod C. Rath Ramesh Sharma S. PrasadThis book presents a collection of articles on various aspects of current research on aging. These include model systems, cellular, biochemical and molecular aspects of experimental aging research, as well as selected intervention studies on age-related diseases.Aging is a global challenge to human society. Children are always in a hurry to become adults, while adults produce offspring and add to the gene pool. However, after adulthood or the attainment of reproductive maturity, all physiological parameters of the living organism start to undergo the aging process. Old age sets in slowly but surely, and usually continues for a prolonged period. If vigor and vitality are the main advantages of adulthood, old age offers the rewards of experience and maturity.Biologists ask questions such as: Why do we age? How do we become old? Is it possible to slow down, postpone or even prevent aging? In turn, medical experts ask: What are the diseases associated with old age? Are there medicines that can help affected elderly patients? In fact both groups are asking themselves how can we add more health to old age.Healthy aging is the dream of every individual. But to achieve this, it is fundamental that we first understand the cellular, biochemical and molecular basis of the aging process in mammalian cells, tissues and intact living organisms, which can serve as experimental model systems in Biomedical Gerontology. Once the biology of aging is understood at the genetic and molecular levels, interventional approaches to aging and its associated diseases may be easier to plan and implement at the preclinical level.
Topics in Clinical Pharmacology and Therapeutics
by Robert F. MarondeDr. Maronde has performed a major service in bringing together a superb array of scholars and clinicians to discuss not only the basic principles in therapeutics and clinical pharmacology but also the application of those principles to a wide range of clinical problems. Inclusion of chapters on adverse drug reactions, drug overdose, nonmedical prescription drug use, physician prescribing patterns, and the pharmaceutical industry makes this a particularly valuable book for clinicians. It is increasingly important that clinicians be well grounded in the principles of pharmacodynamics and pharmacokinetics because more and more of our patients are aging and cannot be treated as young or middle-aged adults. Elderly patients are liable to either drug overdose or underdose if traditional dosage formulas are followed because of changes in drug metabolism, drug distribution within the body, drug excretion, or changes in receptor site sensitivity. Because the elderly often present with mUltiple chronic diseases and require a variety of medications, they are more prone to medication errors, drug-drug interactions, and adverse drug reactions. The inclusion of three excellent chapters relating to drug-drug interactions, adverse drug reactions, and drug overdose is most welcome and is a valuable addition to this outstanding text on therapeutics and clinical pharmacology. Adverse drug reactions present a potentially serious problem for any patient for whom drugs are prescribed and particularly for those who must take multiple prescriptions.
