...years a measure of a person’s cumulative cigarette consumption over a long period of time. It is expressed as the number of packs (assuming 20 cigarettes in a pack) smoked per day multiplied by the number of years of smoking: number of pack years = (packs [or cigarettes/20] smoked per day) × (years smoking) . For example, a patient who has smoked 15 cigarettes a day for 40 years has a (15/20) × 40 = 30 pack-year smoking...

The Q-angle is normally less than 15° in men and 20° in women when the quadriceps are relaxed. The angle becomes smaller when the quadriceps are contracted. A Q-angle greater than 20° increases the likelihood of the quadriceps pulling the kneecap laterally, increasing the risk of knee disorders such as patellofemoral pain syndrome ....

...capacity, or volume of oxygen consumed per minute per kilogram body weight. The average VO 2 max for a 20-year-old female is between 32–38 ml kg −1 min −1 ; for a 20-year-old male it is 36–44 ml kg −1 min −1 . Endurance athletes tend to have a higher VO 2 max than those involved in power activities. The highest VO 2 max value recorded for a male is 94 ml kg −1 min −1 for a champion Norwegian cross-country skier. Aerobic training may improve VO 2 max by 15–20% or more. Such increases are due to changes within the cardiopulmonary transport system and tissue...

... n. 1. the mammary gland of a woman: one of two compound glands that produce milk. Each breast consists of glandular lobules – the milk-secreting areas – embedded in fatty tissue (see illustration). The milk passes from the lobules into ducts, which join up to form 15–20 lactiferous ducts . Near the front of the breast the lactiferous ducts are dilated into ampullae , which act as reservoirs for the milk. Each lactiferous duct discharges through a separate orifice in the nipple. The dark area around the nipple is called the areola . See also ...

...ultrasound ( ultrasonography ) n. A technique using ultra-high frequency sound waves (1–20KHz) to visualize soft tissues. Sound waves are produced by mechanical vibrations using a piezoelectric transducer to convert electrical signals into sound waves, which are transmitted through the tissues as a series of pulses. It is becoming increasingly used for diagnostic purposes in the head and neck region in which shorter wave lengths (7–12MHz) are utilized; it is often the first imaging modality of choice for soft tissue lesions including lymph nodes and ...

...acids The building blocks of protein. They have an amine group (–NH 2 ) and a carboxyl group (–COOH ). There are about 80 naturally occurring amino acids, but only about 20 are used in proteins. Some of the amino acids can be obtained only from the diet: these are called essential amino acids and are used to manufacture the others. Amino acids may be used as an energy source during endurance activities, but they probably supply no more than 10% of the body's demands. Some amino acids, such as gamma-aminobutyric acid and glutamate function as...

... n. the arrangement of teeth in the mouth. The primary dentition comprises the teeth of young children. It consists of 20 teeth, made up of incisors, canines, and molars only. The lower incisor erupts first at about 6 months of age, and all the primary teeth have usually erupted by the age of 2½ years. The lower incisors are shed first at about 6 years of age, and from this time until about 13 years old both primary and permanent teeth are present; i.e. there is a mixed dentition . The permanent dentition consists of up to 32 teeth, made up of...

...primary (deciduous) dentition The first set of teeth which erupt into the mouth. Each mouth quadrant has 5 teeth—2 incisors anteriorly, 1 canine distal to the 2 incisors and 2 molars distal to the canine—to make a total dentition of 20 teeth. The incisors erupt at 6–9 months of age, followed by the first molars at 12–14 months, the canines at 16–18 months, and finally the second molars at 24–30 months. There can be considerable variation in eruption dates, although eruption of the central incisors after the lateral incisors usually indicates some pathology....

...contusions, sprains, and strains). Ice reduces swelling and internal bleeding, reduces the metabolism of injured tissue, and decreases the activity of pain receptors. Generally, the ice is applied for at least the first 24–48 h after the injury, for periods no longer than 20 min, and with intervals of at least 30 min between applications. Evidence now suggests that intermittent icing for up to 7 days may be beneficial, particularly for severe bruises, There are many ways of applying the ice, but usually it is wrapped in a wet towel; if ice is applied...

...extended period of time there is a marked loss of mineral below the tooth surface, resulting in the appearance of a white spot lesion on the enamel. Microscopically, enamel caries starts as a wedge shape with the point towards the dentine and an intact outer layer of enamel about 20–50µm thick. The lesion is reversible at this stage. Enamel caries tends to occur in areas of stagnation where the plaque is not readily removed, such as in tooth pits and fissures, interproximal areas, or around poorly contoured restorations. If the acidic condition persists, the...
