Outcome after successful resuscitation of babies born with apgar scores of 0 at both 1 and 5 minutes.

OBJECTIVE: Our purpose was to evaluate the outcome of infants who underwent successful resuscitation after initial Apgar scores of 0 at both 1 and 5 minutes. STUDY DESIGN: Eligible infants were identified through the perinatal database at the University of Tennessee, Memphis. Hospital records and long-term outcomes, where available, of babies who met the above criteria occurring between January 1986 and February 1999 were reviewed. RESULTS: Thirty-three of 81,603 infants (0.4/1000 births) met our study criteria. Twenty-two (67%) babies died during hospitalization. Mortality decreased significantly from 100% for babies with a birth weight of <750 g to 38% for those weighing > or =2500 g at birth (P =.03). All 6 babies delivered before 26 weeks' gestation died. The incidence of 10-minute Apgar scores >0 was significantly higher among survivors than among those who subsequently died (82% vs 33%, P <.05). Nine survivors had hypoxic-ischemic encephalopathy diagnosed before discharge. Of the 7 infants with available follow-up, 4 had significant persisting morbidity. Two infants had normal neurologic examinations at follow-up. CONCLUSION: Survival in babies born with 1- and 5-minute Apgar scores of 0 is predicted by birth weight, gestational age, and 10-minute Apgar score. Long-term sequelae are common but not ensured.

Multidrug-resistant typhoid fever.

One hundred children (consecutive) with positive blood culture for Salmonella typhi were studied for clinical profile and complications. The common clinical features were fever (100%), vomiting (58%), abdominal pain (48%), cough (22%) and loose stools (14%) and the Widal test was positive in 75% patients. Eighty per cent of the salmonella isolates were resistant to amoxycillin, chloramphenicol and co-trimoxazole drugs, but all were sensitive to ciprofloxacin and ceftriaxone. Forty patients developed complications: encephalopathy (18), melaena (12), haematemesis (10), epistaxis (4), hepatitis (4), acalculous cholecystitis (4), bowel perforation (3) and nephritis (2). Complications were more frequent in children with multidrug-resistant typhoid. The final antibiotic required to render the children afebrile included ciprofloxacin (80), ceftriaxone, amoxycillin (4), chloramphenicol (4), amoxycillin and gentamicin (4), amoxycillin with chloramphenicol (2), and furazolidone (2). The defervesence time was least with ceftriaxone and greatest with amoxycillin. All the affected children made a complete recovery.

Representation of nociceptive stimuli in primary sensory cortex.

Using fMRI, we observed cortical activity associated with nociceptive hot and cold sensations applied to hand and foot that are not spatially restricted to the corresponding regions of the primary somatosensory cortex (SI). Hot (55-57 degrees C) and cold (0-2 degrees C) tactile stimuli were applied separately to the right hand and foot of eight right-handed subjects. Although somatotopic mapping of hand and foot was observed as expected based on the Penfield homunculus, activations associated with hot during both hand and foot stimulation and subsequently, cold, activated regions unique to each thermal modality irrespective of the body part. This distributed system for thermal information is present at both nociceptive and more neutral thermal intensities (i.e. warm and cool sensations) indicating the presence of distributed sensory processing associated with thermal-related sensations in human primary sensorimotor cortex.

Vitamin A supplementation in post-measles complications.

One-hundred-and-seventy-seven children with post-measles complications divided into two comparable groups were studied for the effect of Vit.A Supplementation. Eighty-nine children received Vit.A in doses of 200,000 units daily on two consecutive days in addition to antibacterials and other supportive care and 88 did not reveice Vit.A. The case fatality rate was 16 per cent in those who received VIT.A, while the same was 32 per cent in those who did not receive Vit.A (P < 0.02). There was no statistical difference in the mortality rate among two groups when the children were suffering from severe malnutrition or encephalopathy (P > 0.1).
