Early postnatal growth evaluation in full-term, preterm and small-for-dates infants.
Postnatal growth patterns of weight, length/height and head circumference in full-term (FTI), preterm (PTI) and small-for-dates (SFDI) infants, are described by using distance and velocity data together with the concept of growth per unit of body weight. The study was performed in 112 healthy Caucasian infants, of a similar socioeconomic status, in Montevideo, Uruguay. Median growth velocity (MGV) and median growth velocity per unit (MGVU) of body size are defined. The authors stress that: (a) growth velocity is related to body mass, (b) a useful evaluation of growth is made by using two consecutive measures with a certain time interval independently of birthweight and gestational age, and (c) expressing growth per day per unit relates well to daily nutritional and other requirements.

Normal growth and development: current concepts.
Human growth and development are a continuum starting at conception. Prenatal growth can only be estimated at present but is an important consideration in an evaluation of a child's developmental status. Postnatal growth can be assessed for size attained (distance curve) or change over time (velocity curve). Velocity curves truly reflect the pattern of growth in stature.

The relationship of plasma guanethidine levels to adrenergic blockade.
Seventeen hypertensive patients receiving guanethidine for therapy were studied to determine the relationship of guanethidine plasma levels to adrenergic blockade. Plasma levels of guanethidine were measured by gas chromatography-mass spectrometry, and adrenergic blockade was defined by determining the venous reflex response to Valsalva maneuver or deep breath. A significant correlation was found between the change in the venous reflex response and the fall in mean standing pressure when guanethidine is given to patients maintained on a sodium restricted diet. A linear relationship was found between dose and plasma guanethidine concentration (p less than 0.0001), but there was a 6-fold interindividual variation in the plasma levels resulting from any given dose. Adrenergic blockade occurred when plasma levels were 8 ng/ml or higher. These results indicate that the large individual variation in dose requirements for the hypotensive effects of guanethidine most likely is not due to requirements for greatly different plasma levels of the drug; that the variation must result from pharmacokinetic determinants of differing plasma levels between individuals or from other factors, such as increased plasma volume, which maintain elevated arterial pressure in the face of adrenergic blockade.
