A foodborne illness is any illness associated with or resulting from ingestion of food. This definition, as in most texts, is intentionally broad to accommodate the diverse methods and agents responsible for foodborne illness. These agents include microorganisms, marine organisms, and fungi, along with their associated toxins, and various chemical contaminants. The organism/agent and the [...]

The common cold is an acute respiratory tract infection characterized by mild coryzal symptoms, rhinorrhea, nasal obstruction, and sneezing. Although the incidence of the cold cannot be clearly defined because of seasonal and locational variability, it is estimated to vary from 3-6 cases per person per year. Children younger than 1 year have experienced an average [...]

A large number of drugs are currently available for reducing BP. Greater than 2/3 of all patients treated for hypertension will need more than one agent.  For example, in ALLHAT, 60 percent of those whose BP was controlled to <140/90 mmHg received two or more agents, and only 30 percent overall were controlled on one [...]

Blood Pressure Control Rates  Hypertension is the most common primary diagnosis in America (35 million office visits as the primary diagnosis).5 Current control rates (SBP <140 mmHg and DBP <90 mmHg), though improved, are still far below the Healthy People goal of 50 percent, which was originally set as the year 2000 goal and has [...]

Evaluation of hypertensive patients has three objectives: (1) to assess lifestyle and identify other cardiovascular risk factors or concomitant disorders that may affect prognosis and guide treatment (table 6); (2) to reveal identifiable causes of high BP (table 7); and (3) to assess the presence or absence of target organ damage and CVD.  Patient evaluation [...]

The accurate measurement of BP is the sine qua non for successful management. The equipment—whether aneroid, mercury, or electronic—should be regularly inspected and validated. The operator should be trained and regularly retrained in the standardized technique, and the patient must be properly prepared and positioned. The auscultatory method of BP measurement should be used.58 Persons [...]

The relationship between BP and risk of CVD events is continuous, consistent, and independent of other risk factors. The higher the BP, the greater the chance of heart attack, HF, stroke, and kidney diseases. The presence of each additional risk factor compounds the risk from hypertension as illustrated in figure 12. The easy and rapid [...]

Because of the new data on lifetime risk of hypertension and the impressive increase in the risk of cardiovascular complications associated with levels of BP previously considered to be normal, the JNC 7 report has introduced a new classification that includes the term “prehypertension” for those with BPs ranging from 120–139 mmHg systolic and/or 80–89 [...]

Data from the National Health and Nutrition Examination Survey (NHANES) have indicated that 50 million or more Americans have high BP warranting some form of treatment. Worldwide prevalence estimates for hypertension may be as much as 1 billion individuals, and approximately 7.1 million deaths per year may be attributable to hypertension. The World Health Organization [...]
