Cranial sonography in preterm infants.

Fifty preterm newborn infants with gestational age of 28-36 weeks were subjected to real time cranial sonography to (a) evaluate the ventricular system and brain parenchyma, (b) determine the incidence of intracranial abnormalities, and (c) to establish the utility and advantages of routine cranial sonography in preterm infants. The lateral ventricular width varied from 6-12 mm (8.67 +/- 1.85 mm) while hemispheric width ranged between 3.68 to 3.95 cm with a mean of 3.84 +/- 0.25 cm. The lateral ventricular ratio ranged from 20.9 to 26.4% and it showed progressive decrease with increasing gestational age. Cavum septum pellucidum was found in 68% of the preterms. Incidental intracranial pathologies were detected in 12% of the preterms screened.

Clinical and bacteriological study of normal and inflamed neonatal conjunctivae.

Maternal vaginal and neonatal conjunctival flora were prospectively studied in a 117 mother baby pairs. The commonest isolates from both vaginal and conjunctival flora were E. coli, Staphylococcus aureus and Klebsiella species. In 85% of mother-baby dyads, isolates from vagina and conjunctiva were similar. The commonest bacterial isolates in neonates with conjunctivitis were Staphylococcus aureus (37.4%), E. coli (27.9%) and Klebsiella species (19.3%). Maternal coitus, infections, rupture of membranes and baby's birth weight and sex did not influence the occurrence of conjunctivitis.

Diagnostic and prognostic utility of C-reactive protein, alpha-1-antitrypsin and alpha-2-macroglobulin in neonatal sepsis: a comparative account.

C-reactive protein (CRP), alpha-1-antitrypsin (alpha-1-AT) and alpha-2-macroglobulin (alpha-2-MG) levels were evaluated serially in 25 healthy and 20 septicemic neonates and then compared as early diagnostic aids and prognostic indicators in this illness. Compared to healthy controls, septicemic neonates had significantly higher mean CRP levels (p less than 0.01). Neonates with septicemia, who recovered, had higher mean CRP levels than the group which died (p less than 0.05). As an early diagnostic aid CRP had a low Youden index, whereas for prognosis its index was higher. Septicemic neonates also had significantly higher mean alpha-1-AT levels (p less than 0.05), 12-24 hours after onset of illness, as compared to healthy neonates. Alpha-1-antitrypsin could not be used as an early diagnostic aid in septicemia, but was useful for predicting outcome. Mean alpha-2-macroglobulin levels did not show significant variation in healthy and septicemic neonates. Lower mean alpha-2-MG levels were observed in neonates recovering from septicemia. As an early diagnostic aid alpha-2-MG had a low Youden index, whereas for prognosis its index was higher. CRP had a higher Youden index than alpha-2-MG for early diagnosis of neonatal septicemia and had a higher index than both alpha-1-AT and alpha-2-MG for predicting outcome in septicemia. Serial use of CRP alone is, therefore, recommended for both purposes.

Evaluation of ceruloplasmin in neonatal septicemia.

Serial serum ceruloplasmin (Cp) levels were estimated in healthy and septicemic neonates, using single radial immunodiffusion. In 25 healthy neonates mean Cp levels were 19.82 mg/dl at birth, 18.20 mg/dl at 12-24 hours, 17.26 mg/dl at 14 +/- 4 days and 17.68 mg/dl at 28 +/- 4 days of life. For the entire neonatal period the mean Cp levels were computed to be 18.24 mg/dl. In 20 culture positive, septicemic neonates, mean Cp levels were 27 mg/dl at onset of disease, 28.65 mg/dl 12-24 hours later and 36.2 mg/dl after 7 +/- 3 days of start of illness (p less than 0.001 for all sampling intervals as compared to healthy group values in first month of life). The mean Cp levels were unaffected by gestational age in both groups. In the septicemic neonates, the mean Cp levels in dying neonates did not differ significantly from recovering neonates for all sampling intervals. It is concluded that estimation of serum Cp levels may help in diagnosis of neonatal septicemia, but it is not useful as an early diagnostic aid or for prognostication.

Complement components in neonatal sepsis.

Complement components C3, C1q, factor B and breakdown products of C3, i.e. C3c and C3d, were evaluated in the diagnosis and prognosis of sepsis in 24 neonates with proven sepsis. The complement components were measured by electroimmunodiffusion and breakdown products by counterimmunoelectrophoresis (CIEP). The babies with sepsis were found to have decreased levels of C1q and factor B as compared with suitably matched healthy controls. No statistically significant depression was observed in C3 levels of infected babies. However, breakdown products of C3, i.e. C3c and C3d, were detected in 58.3% of these babies. The breakdown products of C3 were not present in any of the healthy controls. The degree of depression of complement components was of no prognostic significance in neonatal sepsis.

Specific antibodies in colostrum of north Indian mothers with special reference to their nutritional status.

The anti-S. typhi antibody is predominantly IgA class, and the anti-polio-antibody, antimeasles antibody, anti-E. Coli enterotoxin antibody and anti-S. typhi agglutinins were found adequate in the colostrum samples of well- and under-nourished mothers. No antibody against tetanus toxin was detectable in colostrum samples from mothers of both the groups, although they have been immunized against tetanus toxoid during pregnancy, suggesting thereby that the presence of specific antibody in the mother's breast secretions is associated with the enteromammary axis, leading to the homing of B-lymphocytes which have been specifically sensitized in the gut.

Cord blood lipid levels in low birth weight newborns.

Cord blood cholesterol, triglyceride and FFA levels were estimated in 73 newborns, subdivided into various gestation weight categories (FTAGA, PTAGA, FTSGA and PTSGA). Cholesterol levels were not influenced by birth weight and gestation. Prematurity and growth retardation caused a significant elevation in triglyceride values. FFA levels were not influenced by prematurity, but growth retardation produced a significant increase. Birth weight and gestational age should be taken into consideration before labelling the newborn as hyperlipidemic.
