  • A healthy digestive system is fundamental to supporting human life. Its ability to extract nutrients from the food we eat affects our general well-being in health and our response to illness in ill-health. Disorders of the digestive system range from mild and self-limiting to severe and life-threatening, but affect everyone to some extent and at some point during their life. This chapter provides a general overview of the digestive system, and then explores its components in greater detail. Common conditions are examined through patient scenarios.

  • People who pursue careers in Internal Medicine are drawn to the specialty by a love of patients, mechanisms, discovery, education, and therapeutics. We love hearing the stories told to us by our patients, linking signs and symptoms to pathophysiology, solving the diagnostic dilemmas, and proposing strategies to prevent and treat illness. It is not surprising given these tendencies that internists prefer to continue their life-long learning through problem solving. This book is offered as a companion to the remarkable 17th edition of Harrison’s Principles of Internal Medicine.

  • Anesthesia management is markedly influenced by pregnancy. Pregnancy-induced physiologic alterations may be compounded by labor, pregnancy-associated conditions (e.g., pregnancy-induced hypertension), or intercurrent disease states of the mother or fetus (e.g., heart disease, pulmonary hypertension, diabetes, or isoimmunization). The pregnancy alterations most influencing anesthesia are those of the cardiovascular, pulmonary, and gastrointestinal systems. At term, cardiac output is increased by 30%–40% above nonpregnant levels in the absence of aortocaval compression.

  • The health effects of violence against women are serious, far-reaching, and intertwined. Health care providers have the opportunity and the obligation to identify cases of abuse. For many women in developing countries, a visit to a health clinic for reproductive or child health services may be their only contact with the health care system. The health care sector can capitalize on this opportunity by ensuring a supportive and safe environment for clients, helping providers ask about abuse, and helping women receive the care they need.

  • In recent years, all western industrialized countries, and to a growing extent even many developed and developing Asian nations, have witnessed a remarkable growth in numbers of older people [1]. Future projections anticipate continued increases, particularly in numbers of individuals who are 85 years and older [1]. Although US statistics have indicated recent declines in disability trends [2], overall numbers of older individuals living with disability and functional dependence are likely to increase given projected increases in life expectancy [3].

  • Forces are at work which may be changing the way the general public thinks about the autopsy. The past few decades have seen a consistent, almost depressing drop in autopsy rates across the world. Once considered the foundation of medical science, the autopsy has fallen into relative disfavor. As the authors of this book discuss, the overall autopsy rate in England has dropped to approximately 25%, with 22% representing coroner mandated cases and only 3% attributable to hospital/academic cases.

  • It has been widely acknowledged that Bulgaria’s macroeconomic performance has changed dramatically since 1997. Macroeconomic and financial stability have been restored and economic activity started to recover; inflation was brought down to single-digit numbers, real incomes have been rising and the chronic fiscal gap has been closed. A CBA is an extremely rigid macroeconomic regime which hardens macro-budget constraints as it eliminates direct central bank credits to finance the budget deficit.

  • The major domestic support measure besides the milk quota system is public intervention (buying into storage) for butter and SMP. By administering the market price for butter and SMP through intervention purchases, the EU aims to put a floor on the producer milk price. If market demand is satisfied, minor surpluses or deficits will, in principle, show up through changes in the level of intervention stocks, but the market prices will not fall much below the respective intervention levels. ...

  • In 1991 I was presenter of the BBC’s Watchdog programme, married to my copresenter John Stapleton with a two-year-old son. Life was good. I had never heard of bowel cancer, had no idea that it was the second biggest cancer killer in the UK. So I had no worries that the subtle symptom I had spotted intermittently – just a bit of rectal bleeding – might be serious. When my GP reassured me that it was ‘nothing to worry about’ at my age, ‘probably piles’, I believed him. It was a terrible shock to discover nearly a year later, through my persistence, that I had advanced bowel...

  • The gastrointestinal tract (GI tract) plays dual roles in hwnan physiology: digestion and uptake of nutrients and the more daunting task of maintaining immune homeostasis (protecting the body from potentially harmful microbes, while inducing tolerogenic responses to innocuous food, commensals and self-antigens). The unique architecture ofthe GI tract facilitates both ofthese functions; multiple levelsofinfolding results in an immense overall surface area that allows maximal nutrient absorption while housing the largest nwnber ofimmune cells in the body.

  • Sepsis is a complex syndrome characterized by systemic inflammation in response to infection. It is a significant health problem with an estimated 750,000 new cases in the USA annually [1]. It is also the third leading cause of death in developed countries, equalling the number of fatalities from acute myocardial infarction. The incidence of sepsis has increased in recent decades and is predicted to continue to rise. The high sepsis-related mortalities and the burden on healthcare systems means there is an urgent need to improve the diagnosis and management of sepsis patients....

  • The major 2S albumin allergen from Brazil nuts, Ber e 1, was subjected to gastrointestinal digestion using a physiologically relevantin vitro model sys-tem either before or after heating (100 C for 20 min). Whilst the albumin was cleaved into peptides, these were held together in a much larger struc-ture even when digested by using a simulated phase 1 (gastric) followed by a phase 2 (duodenal) digestion system. Neither prior heating of Ber e 1 nor the presence of the physiological surfactant phosphatidylcholine affected the pattern of proteolysis.

  • The liver is the most important organ in which drugs are structurally altered. Some of the resulting metabolites may be biologically inactive, some active and some toxic (see Chapter 7).The liver is exposed to drugs in higher concentrations than are most organs because most are administered orally and are absorbed from the gastrointestinal tract.Thus the whole dose must pass through the liver to reach the systemic circulation.
