  • (5) In the interim, sonographic studies during pregnancy in women at risk for AIDS may be helpful in identifying fetal intrauterine growth retardation and may help raise our level of suspicion for congenital AIDS.
  • (6) Three types of responses were observed: group A, no inhibition of gastric acid secretion occurred in 17 (40%) ulcer patients and in three (18%) controls (p less than 0.05); group B, inhibition of gastric acidity occurred in seven (16%) ulcer patients and in 12 (71%) controls (p less than 0.05), and group C, retarded gastric acid inhibition occurred in 19 (44%) duodenal ulcer patients and in 2 (12%) controls (p less than 0.05).
  • (7) This new way of thinking is reflected in the 1992 AAMR definition of what mental retardation is (Luckasson et al., 1992).
  • (8) Confirmation of the striking correlation between increased urinary ammonia and lowered neonatal ponderal index may afford a simple test for the identification of nutrient-related growth retardation.
  • (9) Governmental officials as well as medical scientists in Taiwan have worked hard in recent years to develop and to implement various measures, such as prenatal diagnosis and neonatal screening, to lower the incidence of hereditary diseases and mental retardation in the population.
  • (10) A lower than normal percentage of REM sleep in these patients was consistent with their retarded intellectual development, which supports current thinking that REM sleep may be a sensitive index of brain function integrity.

  • (13) However, patients can be taught how to retard the onset of wrinkles by avoiding unprotected sun exposure, unnecessary facial movements, and certain sleeping positions.
  • (14) Between-group responsivity differences suggest developmental retardation in term (38-42 weeks) SGA newborns, but the faster SGA latencies may reflect 'induced' acceleration in auditory neurophysiologic function.
  • (15) Fifty-one severely retarded adults were taught a difficult visual discrimination in an assembly task by one of three training techniques: (a) adding and reducing large cue differences on the relevant-shape dimension; (b) adding and fading a redundant-color dimension; or (c) a combination of the two techniques.
  • (16) Thus, the patient with asymptomatic bacteriuria and a positive FA test is at greater risk of delivering an intrauterine growth-retarded infant.

  • (18) Partial duplication of the proximal part of the long arm of chromosome 5, on the other hand, is associated mainly with musculoskeletal abnormalities including muscle hypotrophy and hypotonia, scoliosis, lordosis, pectus carinatum, cubitus valgus, and genu valgum, in addition to psychomotor retardation.
  • (19) In contrast, the same concentration of isopropanol produced narcosis in the dams, retarded body-weight gain and reduced the feed intake.
