Prognosis of single unprovoked seizure.

201 patients (131 males and 70 females) with mean age of 18 years (range 5-55 years) who presented at median of 6 days after the onset of first unprovoked seizure were studied. They were followed for a mean period of 60 months (range 12-84 months). One hundred and fifty four (76%) patients were treated with anticonvulsant medication (group A) on a non-randomized basis and the remaining 47 patients (24%) were not treated (group B). Both the groups were comparable for age, sex, type of seizure and interval between onset of seizure and consultation. The cumulative risk of recurrence for entire study group was 24% at 1 month, 32% at 6 months, 34% at 12 months, 35% at 24 months and 36% at 36 months. The cumulative risk of recurrence in group A was 23%, 30%, 32%, 33% and 33% as compared to 28%, 36%, 40%, 43% and 45% at 1, 6, 12, 24 and 36 months respectively (p > 0.05). Maximum number of recurrences (67%) occurred within 1 month. No recurrence occurred after 36 months after the onset of first seizure. Age at onset, sex, seizure type, family history of seizure, EEG abnormalities and nature of antiepileptic drugs did not influence the risk of recurrence.

Acinetobacter sepsis in neonates.

Twenty-six neonates were diagnosed to have acinetobacter sepsis during 1986-90, representing 6.5% of all cases of bacteriologically proven sepsis. Of these 19 neonates were low birth weight (LBW) 12 were small for gestational age (SGA). Nineteen neonates had early-onset sepsis. The male to female ratio was 9:17. The hematological profile was suggestive of sepsis in 17 cases. All infants had clinical evidence of multi system infection. Eleven babies died; the cases-fatality rate was 42.3%. Only 15/25 culture isolates were sensitive to gentamicin and resistance to other antibiotics was even more frequent. Acinetobacter was cultured from other sites: eye swabs, skin pustules and umbilical catheter tips. Environmental nursery surveillance cultures done during the study period yielded Acinetobacter once from a crib, but no cases of sepsis occurred around that time. The epidemiological features of this organism illustrate the value of vigilance and precautionary measures.

Computerised neonatal case records: a four year experience.

A computerized system for neonatal case records has been used for the last four years at Kasturba Hospital. The software was developed in-house. The data base can be used to generate discharge summaries, neonatal statistics and epidemiological information. For a single patient, entry of data and printing of the discharge summary takes four to five minutes. Consolidated demographic and epidemiological statistics or selective clinical data for clinical research is easily retrievable. The system is efficient, accurate and easy to operate.

Quantitation of proteinuria using protein-creatinine ratio in random urine samples.

Estimation of proteinuria in children is cumbersome when a 24 h urine collection is needed. In the presence of a stable glomerular filtration rate, the ratio of urinary protein and creatinine should reflect the protein excretion. One hundred samples of urine (24 h and random samples) were collected from 50 children with nephrotic syndrome, 25 with nephrotic syndrome in remission and 25 normal children. The 24 h urine total protein and random urine protein-creatinine ratio were assessed on these samples. Linear regression analysis of the results showed excellent correlation between the values (r = 0.81, p less than 0.001). A random urine protein-creatinine ratio of greater than 3.5 correlated with massive proteinuria, while a ratio less than 0.2 was suggestive of physiological values. The sensitivity, specificity, positive and negative predictive values of the protein-creatinine ratio in massive proteinuria were very high. We conclude that the random urine protein-creatinine ratio can be used reliably to assess the degree of proteinuria in children.

Salmonella typhimurium isolated from bacteraemia.

During a two year period, a total of 15 strains of S. typhimurium were isolated and analysed by phage typing. Of these, 13 were found untypable, while two strains belonged to phage 76 and 22. All the strains were sensitive to Gentamicin and Cephaloridine. All but one showed multiple drug resistance.

Serum apolipoproteins A and B, lecithin: cholesterol acyl transferase activities and urinary cholesterol levels in nephrotic syndrome patients before and during steroid treatment.

Serum apolipoproteins A (Apo-A) and B (Apo-B) and lecithin: cholesterol acyl transferase (LCAT) activities and 24-hour urinary cholesterol levels were estimated in 25 nephrotic children before and during steroid treatment with 4 weeks of daily prednisolone followed by another 4 weeks of alternate-day prednisolone. The patients with untreated nephrotic syndrome (NS) showed significant decrease in serum Apo-A and LCAT activities associated with significant increase in serum Apo-B and urinary cholesterol levels compared to healthy controls (n = 25). Serum Apo-A levels correlated directly and Apo-B levels inversely with the serum albumin concentrations. After a transient elevation, the serum Apo-A level returned to control range by 8 weeks of treatment accompanied by a gradual increase in serum LCAT activity and decrease in urinary cholesterol excretion. Though, the serum Apo-B level was decreased with treatment, it was still significantly high compared to the controls.

Pediatric cancer care in India. A national survey.

A national survey of institutions treating children with cancer was undertaken in April 1988. The 21-item questionnaire included questions on personnel, treatment facilities, support services, attitudes and opinions regarding pediatric cancer care. 73 institutions responded. From the survey, it emerged that pediatricians did not see all pediatric patients with cancer at one-third of the respondent institutions. 50 percent of cancer centres did not have pediatricians. Cancer centres were better staffed with specialist personnel and better support services. Respondents felt that pediatric oncologists and specialist support personnel were necessary for optimal pediatric cancer care and facilities at medical colleges needed to be improved because of the large number of children with cancer treated at these institutions.

Neonatal behavior of small for gestational age infants.

The behavioral pattern of small for gestational age (SGA) infants differs from that of appropriate for gestational age (AGA) infants. Maternal malnutrition and SGA infants being a common problem in our country, we assessed the behavior of 36 full term SGA infants using the Brazelton scale. These infants had an excellent orienting capacity, state control and self quieting. Their motor performance was fair and autonomic regulation showed a good recovery over first 10 days. A comparison of this behavior with full term AGA infants showed a better orientation in SGA infants. Though there was a significant difference in motor, state regulation, and autonomic regulation, by the end of the first month they recovered to the same level as the AGA infants. The pattern of SGA behavior described is at marked variance with most of other reports from abroad.

Intraperitoneal ascariasis.

Seven children with intraperitoneal ascariasis are reported. One of them had two episodes. There were four instances of free worms in the peritoneal cavity, whereas others had peritoneal abscesses containing round worms. It is suggested that peritoneal ascariasis should be suspected whenever a child presents with peritonitis and/or an inflammatory abdominal mass having evidence of ascarial infestation.
