Abstract Introduction Sacrospinal anomalies that may accompany anorectal malformations may cause fecal and urinary incontinence despite proper anomaly treatment. The sacral ratio has been suggested in the determination of both the prognosis in terms of incontinence and the need for further examination for sacrospinal anomalies. The normal and clinically decisive values of sacral ratio are given differently in publications. We aimed to determine the distribution of the sacral ratio in children under 12 months and to develop the sacral ratio percentile card that will enable one to give an age-independent parametric result in clinical evaluations. Materials and Methods The files of patients under 1 year of age who had anteroposterior direct radiography including pelvis were reviewed retrospectively. Sacral ratio was studied for 360 patients, 30 patients per month. Percentile card was developed with LMS software and reference values were used as 1, 2, 3, 4, and 10%. Results The lowest sacral ratio value was 0.514 and the highest value was 0.936. There was no statistical difference between the mean sacral ratio of the cases when they were classified on a monthly basis (p = 0.191). Low percentile values were found slightly different at first 4 months of age. Conclusion Although the mean of sacral ratio does not change significantly during the first year of life, values that are considered pathological for patients are within different percentile limits depending on age. Instead of using sacral ratio with some clinically decisive values, we think that parametric evaluation with the help of the percentile card will increase its clinical value.

During an outbreak of epidemic diarrhea a new serotype of Escherichia coli: E. coli 0127:B8, was isolated from 44 of 145 infants and from 1 nurse among 82 adult personnel in attendance. Among the 44 infants whose rectal swab cultures were positive, 20 were in the first month of life, 16 were 2 to 6 months of age, and 6 were 7 to 12 months of age, a total of 42 being in the first year of life. Severe epidemic diarrhea associated with the presence of E. coli 0127:B8 was characterized by the sudden development of extreme abdominal distention among some of the infants; explosive onset of diarrhea and the presence of a pungent, musty, objectionable odor not noticed around other patients with diarrhea. E. coli 0127: B8 was isolated more frequently while the patients were having diarrhea. Neomycin® was used orally for the specific treatment of patients with diarrhea. The early dosage was small due to our caution in using a new antibiotic. Over the 4 months period of this study the dosage was gradually increased. The average dose was 40 mg./kg./day for the patients with positive cultures and 46 mg./kg./day for those with negative cultures. Of 22 patients with positive cultures, 12 who were treated with Neomycin® alone or in addition to other antibiotics continued to show the presence of E. coli 0127:B8 after Neomycin® therapy had been terminated; however, only 2 of these patients had recurrence of diarrhea, both having had negative cultures while receiving Neomycin®. The administration of Neomycin® to every infant on the 2 wards, regardless of clinical condition, was followed by a decreasing incidence of diarrhea and decreasing detection of E. coli 0127:B8. The dose of Neomycin® was 40 to 50 mg./kg./day. It is our feeling that Neomycin® administered orally was of definite clinical value therapeutically and prophylactically but in the dosage used was inadequate bacteriologically. Four deaths occurred among the 44 infants whose rectal swab cultures were positive for E. coli 0127:B8 and necropsy studies were made on each. A hemorrhagic enteritis was present in 3 infants and in the fourth infant the cause of death was a congenital heart condition. Death of 1 patient with negative rectal swab cultures may very likely be attributed to severe diarrhea. Sera from patients and personnel failed to show the presence of agglutinins for E. coli 0127:B8. in vitro sensitivity tests showed that the order of decreasing bactericidal effectiveness of 5 antibiotics for E. coli 027:B8 was polymyxin, Neomycin®, chloramphenicol, Achromycin®, and Terramycin®. All strains were resistant to dihydrostreptomycin and sodium sulfadiazine. Only the last strains isolated from 2 patients showed increased resistance to Neomycin®, four-and sixteenfold when compared with the first strains isolated from the same patients.

To determine possible characteristics of infant victims of sudden death, we examined 114 items related to the pre- and postnatal histories of 42 pairs of twins one of whom died of sudden infant death syndrome (SIDS) leaving a surviving sibling. Interviews with the parents were conducted after the occurrence of SIDS, and the data were checked with records held by gynecologists and pediatricians. To evaluate the specificity of any factors, we studied a control group of 42 age- and sex-matched pairs of twins, both of whom survived the first year of life. Only 11 of 114 characteristics were significantly related to SIDS: future victims had a smaller weight and height at birth, stayed longer in the nursery, and followed a moving object with their eyes, had head control, and smiled at a later age than their surviving siblings. They also fatigued more often during feeding (11/42) and had reduced arm and neck tonus (9/42). They were described as longer sleepers than their surviving siblings. During sleep, some SIDS twins, but no surviving twin, were found to be cyanotic at least once or pale (4/42) and were repeatedly covered with abundant sweat (8/42). In the control group of normal twins, the occurrence of most of these characteristics was found with a frequency comparable to that seen in the SIDS infants; the specificity of these characteristics is thus considered doubtful. The mean birth weight and height were significantly greater in the control group, and no control infant had an episode of cyanosis or pallor or repeated episodes of profuse sweating observed during their sleep. It is concluded that, if further research validates the occurrence of night hyperhydrosis in some future SIDS victims, this symptom could be a clinical risk factor.

Colour discrimination was investigated in infants aged 4 – 14 months. 250 healthy subjects and 80 subjects with slight defects in basic visual functions (the risk group) participated. A coloured toy was moved in front of the subject and disappeared behind a screen, reappearing after 2 – 3 s at the other side. Sometimes when the toy was hidden, the experimenter replaced it with another one that differed only in colour: yellow was replaced by blue or vice versa (Y/B switch), or red by green or vice versa (R/G switch). The form and size of the toy remained constant. The emotional reaction of surprise showed whether the infant discriminated these colour pairs. The brightness of the stimuli was slightly varied make sure that the infant reacted to the change in colour rather than brightness. About 75% of healthy 4 – 5-month-olds showed good expressive reactions to the Y/B switch, and practically all children did so at 7 – 8 months. The discrimination of red and green develops more slowly: only at 12 months did practically all children show good reactions to the R/G switch. In all children, Y/B discrimination preceded R/G discrimination. The mean difference between the numbers of children discriminating these two pairs was 7.6%. The infants of the risk group were as good as their healthy age-mates in Y/B discrimination, but performed significantly less well on R/G: the mean difference between the numbers discriminating the former but not the latter was 17.0%. Possible reasons for the retardation of chromatic discrimination in the risk group are discussed.

The Mean

The mineralization coefficient (M.C.) (the amount of nitrate nitrogen formed in one season in sift, by bare fallowing the soil, as a percentage of the amount of organic nitrogen in the topsoil at the onset of the season) was measured on two soils at Katherine, N.T. The determination of M.C. is regarded as useful in evaluating the 'true' decomposition constant of a soil under annual cropping conditions. Its relation to the 'apparent' decomposition constant is discussed. Tippera clay loam had a mean M.C. of 4.80 per cent, and the fluctuations around the mean were positively related to amount of rainfall. The M.C. for Blain sand dropped from 12.5 per cent in the first year of cultivation to 5.0 per cent in the third and fourth years. The data indicate that the initial high nitrogen yields on the sandy soil will in time decline to a low level unless a legume crop is incorporated in the cropping system.

Early exposure to sweet tastes predicts similar food preferences and eating behavior in later life and is associated with childhood obesity. The aim of this study was to explore the associations of early (during the first year of life) and subsequent intake of sugar-sweetened beverages (SSBs) with 4-y caries trajectories among Scottish young children. We used data from 1,111 Scottish children who were followed annually from age 12 to 48 mo (4 sweeps in total). SSB intake was reported by parents in every sweep. SSB intake was broken down into 2 components, the initial SSB intake and the deviation over time from that initial value. Childhood dental caries was clinically determined (including noncavitated and cavitated lesions) every year. The association of SSB intake with baseline decayed, missing, and filled tooth surfaces (dmfs) (intercept) and rate of change in dmfs over time (slope) was examined in 2-level linear mixed-effects models, with repeated observations nested within children. Both the initial SSB intake and the deviation from the initial SSB intake were positively associated with steeper caries trajectories. By sweep 4, the predicted mean dmfs difference was 1.73 between children with low and high initial SSB intake (1 standard deviation below and above the mean) and 1.17 between children with low and high deviation from their initial SSB intake (1 SD below and above the mean). The findings of this prospective study among Scottish young children provide evidence that the introduction of SSBs during the first year of life can put children in a trajectory of high levels of dental caries. They support current recommendations to avoid sugars for very young children and interventions targeting early feeding practices for caries prevention.

In a first part, the present status of the HIPPARCOS mission is described. Despite the degradations and failures of gyroscopes, it is still hoped that a 4 1/2 mission duration will be reached. The first-year of data has been reduced by both FAST and NDAC consortia. For the best 46200 observed stars, the distribution of standard errors in positions has a maximum of 1.5 mas in latitude and 1.8 mas in longitude and the mean standard error for parallaxes is of the order of 3 mas. The comparison of results obtained by both consortia shows that the differences are small and quite consistent with the announced internal precisions. Magnitude measurements are precise to 0.02 magnitude for a 4 second observation. The precision to be expected for double star observations is also given. The main new result is that the magnitudes of the components are obtained with a few hundredths of a magnitude precision. This allows to devise a new method of mass determination based upon the parallax and a recalibrated mass-luminosity diagram. The parallax dependence of the results is much more favourable than in the case of the classical determination of masses using orbital motions.

SummaryThe paper reports on a study, conducted in four successive seasons, of sexual development and breeding activity in females of the Iceland breed, the only breed of sheep kept in the country. The ewe lambs normally attained puberty in their first year of life, on average at 7 months of age, with marked individual variation in both age and body weight at first oestrus. Ewe lambs always showed oestrus on average slightly later than mature ewes (2–9 years), the mean date of onset of the breeding season of the latter being 8 December, however, with considerable individual variation. Furthermore, ewe lambs had a shorter breeding season (1–4 months) than ewes (4–6 months) and they appeared to experience more silent heats resulting in less regular cyclic activity. There seemed to be a minor increase in the duration of the oestrous cycle with age and ewe lambs clearly exhibited shorter oestrus (heat) than ewes. With seasonal breeding activity ranging from November to May the mid-breeding season occurs some 4–7 weeks after the shortest day.

Vitamin D is essential for calcium absorption and for maintaining bone health in the pediatric population. We conducted a retrospective study to establish the profile of a child aged under 3 years old with vitamin D deficiency in the context of correct prophylaxis, on a cohort of 49 children from two general practitioner offices. From the study group 30.6% of children (15 cases) had low vitamin D levels. The mean serum 25(OH)D level was 41.5±16.6 ng/ml. Regarding nutrition in the first year of life, breastfeeding predominated (83.7% of patients), and only 8.16% of patients had clinical signs of rickets. So, low serum levels of vitamin D can also be found in children who have successfully received correct prophylaxis with vitamin D. Keywords: vitamin D, children, rickets

A study was devised to determine whether levels of fetal hemoglobin (HbF) synthesis are elevated in infants with bronchopulmonary dysplasia (BPD) when compared with the levels of HbF synthesis found in normal control infants. Twelve infants with BPD, whose postconceptional ages ranged from 40 to 62 weeks, were studied. The mean (±SD) gestational age and birth weight was 29 ± 1.9 weeks and 1289 ± 376 g, respectively. Elevation infants matched for birth weight, gestational age, and postnatal age served as the control subjects. Blood samples were incubated in an amino acid mixture containing [14C]leucine. The adult hemoglobin and HbF were then separated by column chromatography on diethylaminoethyl-Sephadex. The results demonstrated that the mean (±SD) level of HbF synthesis in infants with BPD was significantly higher than that in the control infants (42.6 ± 22.9% vs 18.8 ± 12.8%; P < .01). When levels of HbF synthesis in the infants with BPD and the control infants were compared with data previously reported in normal infants, 7 of the 12 infants with BPD, but none of the control infants, were synthesizing amounts of HbF greater than would be expected for their postconceptional age. The results suggest that cardiopulmonary insufficiency could stimulate HbF synthesis during the first year of life as a result of an erythropoietic response to hypoxemia.

Four years of experience in the evaluation and management of lead intoxication in the first year of life were reviewed. This study was conducted in a lead referral program within the state of Massachusetts, whose comprehensive lead laws include extensive (and now mandatory) lead screening of all children. Over the period of study, 50 (14%) of 370 new patients enrolled in the program were Infants aged 12 months or younger. Median age of these infants was 11 months (range 1 through 12 months). Mean peak lead level was 39.0 µg/dL while the mean peak erythrocyte protoporphyrin concentration was 111.9 µg/dL of whole blood. Thirty-two percent of infants were ambulatory at the time lead intoxication was diagnosed; only 24% had a history of pica. Twenty-six percent of parents were welfare dependent. Apparent sources of plumbism included household renovation (n = 20), direct ingestion of paint chips (n = 10), formula preparation with lead-contaminated water (n = 9), lead dust importation (n = 1), and congenital exposure to elevated maternal lead level (n = 1). In 9 cases the source was not found. When this profile was compared with that of a randomly selected group of 47 children aged 18 through 30 months, who were seen in the lead program during the same interval, apparent sources of intoxication in the older group were paint chip ingestion (n = 41), household renovation (n = 2), and unknown (n = 4) (P < .0001). On the basis of these data, it is concluded that lead intoxication in infants is common and has significantly different origins from that in toddlers. Lead intoxication from infant formula reconstituted with contaminated water may account for many of these cases. These findings support recommendations that lead screening begin at the age of 6 months for children with any likelihood of lead exposure.
