Harvard Medical School; Chairman, Department of Medicine, and Harrison's Principles of Internal Medicine (HPIM), the premier medical textbook. Here's another link- Harrison's Principles of Internal Medicine 19th Edition PDF. Hi there! Below is the link to a pdf copy of the new Harrison's Principles of Internal Medicine 19th Edition book. I got this copy from a clinical.

A resultant twitch of the nose or lips suggests low calcium levels. This is now known as the Chvostek sign. EMG studies reveal single or often grouped motor unit discharges at low discharge frequency during tetany episodes.

Oct J Am Soc Nephrol. Guyton and Hall textbook of medical physiology 12th ed. The morphology of the organism may be classified as cocci , diplococci , bacilli also known as "rods" , spiral-shaped or pleomorphic.

Additional classification occurs through the organism's ability to take up the Gram stain and counter-stain ; bacteria that take up the crystal violet dye stain are referred to as "gram-positive," those that take up the counterstain only are "gram-negative," and those that remain unstained are referred to as "atypical. The most commonly encountered groupings of bacteria include gram-positive cocci, gram-negative bacilli, atypical bacteria, and anaerobic bacteria.

For example, 1st-generation cephalosporins are primarily effective against gram-positive bacteria, while 4th-generation cephalosporins are generally effective against gram-negative bacteria.

Empiric antibiotic therapy[ edit ] Main article: Empiric therapy Empiric antibiotic therapy refers to the use of antibiotics to treat a suspected bacterial infection despite lack of a specific bacterial diagnosis. Definitive diagnosis of the species of bacteria often occurs through culture of blood, sputum, or urine, and can be delayed by 24 to 72 hours.

Then, the most likely bacterial species for this type of infection are identified for lobar pneumonia in healthy adults: S. Lastly, an antibiotic or group of antibiotics are chosen that are reliably effective against the potential species of bacteria for example in lobar pneumonia, levofloxacin covers the majority of relevant bacteria.

Clinicians often aim to choose empiric antibiotic combinations that cover all appropriate bacteria but minimize coverage of inappropriate bacteria, as to reduce the incidence of antimicrobial resistance see below. Carbohydrates Carbohydrates can be classified as monosaccharide e. Carbohydrates must be reduced to the simplest form of glucose through digestion before your body can make use of them. In some situations, the body can compensate for decreased levels of carbohydrates by using alternative energy pathways such as burning fatty acids.

Protein Protein is important for the production, maintenance and repair of tissues in the body. When energy intake is insufficient, protein intake must be raised.

This is because ingested proteins are preferentially directed towards glucose sugar synthesis and oxidation. The tissues and organs in the body are made up of protein and protein compounds. Enzymes biological catalysts , antibodies and hormones also consist of protein. The building blocks of protein are called amino acids.

The body can make all of the 20 amino acids except eight, which are termed essential amino acids.

These are isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine. Histidine is essential only for infants. For adults, the recommended dietary allowance of protein is about 0.

Animal products tend to have the highest amount of proteins, followed by legumes beans , cereals rice, wheat, corn and roots. Protein derived from plants lack one or two essential amino acids. However, a good combination of plant-based protein can be of equal value to animal protein. For example, legumes lack methionine but have adequate amounts of lysine. Cereals, on the other hand, lack lysine but have a lot of methionine. Therefore, a mixture of rice and beans will supply all the essential amino acids.

Supplemental Nutrition Assistance Program: Examining the Evidence to Define Benefit Adequacy

Excess protein cannot be stored in the body, so we need to consume protein daily. Consuming too much protein is not recommended because it promotes increased calcium excretion through urine , which increases the risk of developing osteoporosis.

Additionally, too much protein intake may lead to a greater concentration of the amino acid homocysteine in the blood, and the subsequent conversion to thiolactone.

Thiolactone is associated with increased levels of atherosclerosis and endothelial damage. Fats and oils Most of the fats we consume occur in foods as triglycerides.

A triglyceride is comprised of three fatty acid molecules attached to a glycerol molecule.

Fatty acids are made up of carbon and hydrogen atoms and can be either saturated or unsaturated. Saturated fatty acids SFA have the maximum number of hydrogen atoms attached to the carbon chain, while unsaturated fatty acids have less than the required hydrogen atoms. For example, monounsaturated fatty acids e. Monounsaturated fats are found mainly in nuts, avocados, olive oil, canola oil, grapeseed oil, peanut oil, flaxseed oil, sesame oil, corn oil, safflower oil, sunflower oil, etc.

Polyunsaturated fatty acids PUFA have more than two hydrogen atoms missing e. Linoleic and linolenic acids are regarded as essential fatty acids EFAs because the body cannot make them. There are two categories of EFAs: omega-3 and omegaThey generally act as coenzymes.

Essential nutrient requirements Nutrients can be described as the chemical components of food and can be classified into six broad groups: carbohydrates, proteins, fats, vitamins, minerals and water.

Hypocalcemia is not a term for tetany but is rather a cause of tetany. It is required for growth in all stages of life. Looking for this for a long time.

Pregnant or lactating women, alcoholics and the elderly are more likely to suffer from vitamin B deficiency. Carbohydrates Carbohydrates can be classified as monosaccharide e.

Thanks so much.
