We describe a neonate having congenital pyloric atresia (CPA) associated with epidermolysis bullosa (EB), also known as Carmi syndrome. The case is unusual as it was complicated with pharyngo-esophageal perforation (PEP) and a definite family history of EB in pervious generations could be recorded.
Neonatal hyperbilirubinemia is a common problem in newborn nurseries and manifest clinically as jaundice. Nearly 25-50% of all newborns and a much higher percentage of premature babies develop hyperbilirubinemia. This is mostly physiological, but a small percentage of these babies have pathological jaundice, requiring detailed investigations and management. It is also absolutely essential to consider a possibility of extra-hepatic biliary atresia early, during management of a case of neonatal direct hyperbilirubinemia as early surgical intervention results in a better outcome in EHBA. This article aims to describe the diagnostic approach to neonatal hyperbilirubinemia with special emphasis on conditions requiring surgical intervention also it throws light on present status of EHBA in Indian circumstances.
BACKGROUND: When used for induction of anesthesia, ketamine usually increases intraocular pressure (IOP). However, the effect of low doses of ketamine, which are used for parental separation in children, is unknown. We studied the effect of two different doses of ketamine on IOP in anesthetized children. METHODS: Forty children age 1 to 6 years who met American Society of Anesthesiologists physical status I criteria scheduled to undergo surgery were randomly selected to receive either an induction dose (6 mg/kg) or a low dose (3 mg/kg) of ketamine intramuscularly. Anesthesia was induced and maintained with halothane, and ketamine was injected 10 minutes after induction. Intraocular pressure was measured using a Perkins applanation tonometer before ketamine administration and every 5 minutes thereafter for 20 minutes by an observer who was unaware of the ketamine dose used. 10.8 +/- 2.2 mm Hg to 12.6 +/- 2.8 mm Hg at 5 minutes and 11.9 +/- 2.5 mm Hg at 10 minutes after administration of ketamine in the induction-dose group. There was no significant change in IOP after administration of ketamine in the low-dose group. Intraocular pressure was significantly higher in the induction-dose group compared to the low-dose group at 5 minutes after administration of ketamine. More patients in the induction-dose group had postoperative airway obstruction and sedation than in the low-dose group. CONCLUSIONS: In children anesthetized with halothane, ketamine had a dose-dependent effect on IOP, with 6 mg/kg of the drug causing a small increase in IOP at 5 to 10 minutes and 3 mg/kg not altering the IOP. The higher dose of ketamine also was associated with an increased incidence of postoperative complications.
