Ultrasonic patterns of intrauterine fetal growth in a Latin American country.
Head circumference and its cross-sectional area, biparietal and fronto-occipital diameters, abdominal circumference and its cross-sectional area, and the transverse and anteroposterior diameters were measured in 30 healthy single fetuses from normal pregnancies by means of ultrasound. The 5th, 50th and 95th percentiles of distance and velocity curves are described. The comparison of the values of a perimeter (abdominal or cephalic) measured directly from the photograph or calculated by the ellipse formula, showed a straight correlation. The use of the ellipse formula in current practice may simplify and reduce the cost of this technology.

HCS, estriol and oxytocinase in maternal serum and neonatal condition in high risk pregnancies.
In order to find a reliable index of fetal wellbeing, maternal estriol, hCS and oxytocinase levels were related with condition of the neonate. Fifty six high risk pregnancies were studied. Estriol and hCS were determined by specific radioimmunoassay and oxytocinase with a colorimetric method. The condition of the newborn was evaluated by the APGAR score. Neonates were divided into two groups, depressed (APGAR score 0-6) and vigorous (APGAR score 7-10). When the mean birthweights of both groups were statistically different, maternal estriol levels were corrected to avoid the influencing factor of newborn weight. Mean maternal estriol level corresponding to vigorous newborns was 46.73 ng/ml. This value was statistically higher than that corresponding to the group of depressed newborns, which was 26.25 ng/ml (Fig. 1). The mean birthweight of depressed infants (2,382.75 g) was statistically lower than that of the vigorous group (3,044.75 g). The corrected mean maternal estriol values of vigorous neonates (45.44 ng/ml) was different from that of depressed ones (25.14 ng/ml) (Fig. 2). When patients were divided according to maternal diseases (diabetes, vascular pathology, Rh sensitization) serum estriol levels of the mother were statistically different according to the Apgar score of the newborns. There was no significant difference between serum hCS and oxytocinase levels of mothers with depressed and vigorous newborns. Discarding fetal weight as an influencing factor in maternal hormone level, our results indicate the suitability of maternal serum estriol determinations to predict condition of the newborns in high risk pregnancies.

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.

Blood acid-base balance at birth in neonates from labors with early and late rupture of membranes.
The purpose of this study was to determine whether the early artificial rupture of the amniotic membranes performed to shorten the duration of an otherwise normal labor and delivery might have potentially deleterious effects on the fetus that would be reflected in the neonate. In 38 infants delivered at term, acid-base balances and O2 and CO2 pressures were obtained in umbilical arterial and venous blood at birth, prior to the first inspiration. For the purpose of the study the infants were divided into two groups: group I infants were born after a normal labor in which the amniotic membranes were permitted to rupture spontaneously at full cervical dilatation; group II infants were born after a labor in which the membranes were ruptured artificially when cervical dilatation was 4 to 5 cm. There was no evidence of fetal distress, and all infants were vigorous at birth. The pH of umbilical venous blood was greater in the group with late rupture of the membranes (fiftieth percentile [P50] = 7.36) than in those born after early amniotomy (P50 = 7.30) (p less than 0.01). The pH values of umbilical arterial blood were also higher in the group I infants (P50 = 7.31) than in those born after amniotomy (P50 = 7.25)(p less than 0.025). These differences were also observed in the 19 neonates in whom the cord was not encircled around the neck at the time of birth. The PCO2 in umbilical venous blood was less, and the hemoglobin saturation was greater (P less than 0.05) in group I infants than in those of group II. It is possible that the influence of early amniotomy on fetal pH may be deleterious in infants born after high-risk pregnancies in which the uteroplacental circulation is impaired.

[Cost-effectiveness of individualized enteral nutrition by a nutrition support team in laryngectomized cancer patients].
The purpose of this study was to evaluate the effectiveness of a Nutritional Support Team (NST) in the control and follow-up of enteral nutrition (EN) in patients subjected to laryngectomy as a result of neoplasia. The study was performed on two groups of patients (A and B) who had been admitted into the Otorhinolaryngological Department, and who required EN by nasogastric tube during the postoperative period. Group A consisted of 20 patients in whom EN was based on standard guidelines, with a daily intake of 11.1 g of Nitrogen and 2.000 kcals. Group B included 23 patients who received EN individually, using NST with a daily intake of Nitrogen of between 8 and 21 g, and energy intake of between 2.000 and 3.000 kcals. The total cost of nutrition was calculated using the following partial costs: diet, administration, laboratory analysis and NST head responsible for follow-up of Group B. Individualized EN was more effective in nutritional terms than a standard diet in all patients. Using this form of treatment, positive Nitrogen balance were achieved, levels of seric albumin were maintained as well as weight, and complications were reduced. The average cost of nutrition per patient in Group B was 46.258 pesetas and in Group A, 43.963 pesetas. However, in the latter Group, there was an average additional weight loss of 4 kg per patient, and an increase in cost effectiveness ratio of 573 pesetas in weight gained in Group B compared to Group A.
