A six-week-old male infant was admitted for investigation of cholestasis and pale stools. He became lethargic and apnoeic with prolonged seizures after a percutaneous liver biopsy. Subsequent investigations showed conjugated hyperbilirubinaemia, elevated liver enzymes, and hypoglycaemia. The radinuclide hepatobiliary scintigraphy was non-excretory. After an operative cholangiogram, the infant developed Addisonian-like crisis with bradycardia, hypotension, respiratory distress, metabolic acidosis, hypoglycaemia, hyponatraemia, and hyperkalaemia. Blood investigations confirmed congenital hypopituitarism. Hormone replacement therapy with L-thyroxine and cortisone acetate resulted in dissolution of jaundice and the reduction of the liver size.

Malaria continues to be a problem for children returning or immigrating to industrialized countries from tropical regions. Proper diagnosis begins with clinical suspicion. In nonimmune children, malaria typically presents with high fever that might be accompanied by chills and headache. Symptoms and signs may be more subtle in partially immune children, and anemia and hepatosplenomegaly may also be present. Children may present with respiratory distress and/or rapidly progressing cerebral malaria that manifests as altered sensorium and, sometimes, seizures. Thick blood smears help to determine when infection is present, but a single smear without parasites is not sufficient to rule out malaria. Thin blood smears aid in identifying the species of parasite. Treatment must include careful supportive care, and intensive care measures should be available for treating children with complicated Plasmodium falciparum malaria. Medical regimens can include mefloquine, atovaquone-proguanil, sulfadoxine-pyrimethamine, quinine or quinidine, clindamycin, doxycycline, chloroquine, and primaquine.

Organophosphate (OP) insecticide toxicity is the leading cause of major morbidity and death in the insecticides class. The clinical syndrome of OP toxicity varies widely, ranging from the classic cholinergic syndrome to flaccid paralysis and intractable seizures. The mainstays of therapy for OP-poisoned patients are atropine, pralidoxime, and benzodiazepines. Tachycardia is not a contraindication to treatment with atropine in OP toxicity. Atropine should be administered to alleviate respiratory distress, symptomatic bradycardia, and as an adjunct to benzodiazepines to alleviate seizure activity. Atropine should not be administered systemically to alleviate miosis. In acute OP toxicity, a continuous pralidoxime infusion should be considered. Intermediate syndrome and OP-induced delayed neuropathy may occur in select patients with OP poisoning.

Paroxetine, a selective serotonin reuptake inhibitor (SSRI) may be given in severe cases of maternal depression and panic disorders during pregnancy. However, it may lead to severe withdrawal symptoms: respiratory distress, jitteriness, convulsions, hypoglycaemia, an impaired muscle tone and necrotising enterocolitis. These symptoms, also called neonatal withdrawal syndrome, may last up to one month. We report a girl born at 37 weeks of gestation presenting 12 hours after birth with hypopnea, bradycardia and a decreased muscular tone of unknown origin. The child was transferred to the NICU and was intubated and ventilated mechanically. Within the first days the patient also developed cerebral seizures. The EEG showed severe abnormalities. Later we learned that the patient's mother had been treated with Paroxetine during pregnancy. The patient recovered after two days of ventilation and anticonvulsive medication with phenobarbital. The EEG result showed a siginificant improvement. At day 10 she was discharged in good condition. Recognition and treatment of the presented neonatal problems could have been more effective and faster, if the attending pediatricians had been informed earlier about the maternal medication with SSRIs. Neonates of mothers who were treated with SSRIs during pregnancy should be monitored. Paroxetine withdrawal syndrome should be considered as one of the differential diagnosis of neonatal encephalopathy.

To evaluate the independent contribution of absent or reversed end-diastolic umbilical artery Doppler flow (AREDF) in the prediction of subsequent adverse neonatal outcomes, we performed Doppler examinations on 270 preeclamptic women with a singleton pregnancy. The end-point variables were low Apgar scores and adverse neonatal outcomes (respiratory distress syndrome, intracranial hemorrhage, sepsis, seizures, jaundice, hypoglycemia, hypocalcemia, thrombocytopenia, polycythemia, and neonatal mortality). Stepwise logistic regression was used to control for gestational age, oligohydramnios, and fetal growth restriction. Infants with AREDF had an increased frequency of hypoglycemia (odds ratio=1.7) and polycythemia (odds ratio=1.7), whereas the remaining neonatal outcomes were explained by gestational age and growth restriction. Therefore, live-born infants of preeclamptic patients with AREDF velocities, independent of prematurity and growth restriction, are prone to hypoglycemia and polycythemia.

The developing brain has an increased susceptibility to seizure activity, and neonatal seizures can adversely affect neurodevelopmental outcome. This study aimed to determine the incidence of neonatal seizures in very low birthweight infants and to identify perinatal and postnatal factors associated with the occurrence of clinical seizures. A population-based cohort of 6525 very low birthweight infants born from 1995 through 1999 comprised the study group. Maternal, perinatal, or postnatal variables that showed a significant association with neonatal seizures in a univariate analysis were tested by a multiple logistic regression to assess the independent effect of each variable on the risk of seizures. The overall incidence of seizures was 5.6%. Significant independent predictors of neonatal seizures were decreasing gestational age, male gender, respiratory distress syndrome, pulmonary air leak (pneumothorax and pulmonary interstitial emphysema), intraventricular hemorrhage, periventricular leukomalacia, patent ductus arteriosus, surgical ligation of patent ductus arteriosus, necrotizing enterocolitis, and surgical treatment of necrotizing enterocolitis. Neonatal seizures appear to be associated with major morbidities and surgical interventions in very low birthweight infants. Continuous electroencephalographic monitoring could be warranted in infants following surgical treatment.

Wolf-Hirschhorn syndrome (WHS, OMIM 194190) is a chromosomal disorder characterized by retarded mental and physical growth, microcephaly, Greek helmet appearance of the facies, seizures/epilepsy. Closure defects of lip or palate, and cardiac septum defects occur in 30-50% of cases. Its cause is a deletion in the short arm of chromosome 4. We present a male patient, born after 37 weeks gestation, as the fourth pregnancy of non-consanguineous healthy parents, with unilateral cleft lip and palate, hypertelorism, a right-sided ear tag, and mild epispadias. At age 10 weeks he developed acute respiratory distress and acute bowel obstruction requiring emergency laparotomy. This revealed a left-sided posterolateral diaphragmatic defect, type Bochdalek, with incarceration of the small intestines necessitating major bowel resection. Clinical genetic investigation suggested a chromosome anomaly, but regular karyotyping was normal. However, FISH analysis showed a microdeletion in the short arm of chromosome 4 (4p-), consistent with WHS. A combination of this syndrome with congenital diaphragmatic hernia (CDH) has been rarely described. CDH can present either as an isolated defect at birth, or with multiple congenital abnormalities, or as part of a defined syndrome or chromosomal disorder. Therefore CDH, although not common in WHS, can lead to its diagnosis relatively early in life. We strongly recommend a clinical genetic evaluation of each CDH patient with facial anomalies taking into consideration 4p- deletion syndrome.

In view of very limited availability of paediatric intensive care (PIC) facilities in developing countries, it is important to define priorities and recognise children who might benefit most from PIC. The objective of this retrospective, descriptive analysis was to identify the clinical indicators for intensive care in children with acute bacterial meningitis (ABM). The study included 220 children aged between 1 month and 12 years with ABM admitted to the paediatric services of an urban, tertiary-care, teaching hospital in northern India from July 1993 to December 1996. Of these, 88 were transferred to the PICU by the primary physician, 59% were comatose (Glasgow coma score <8), 44% had raised intracranial pressure (ICP), 24% were in shock and 42% had respiratory distress/failure. Seizures occurred during their illness in 64 children, 34 of whom had refractory status epilepticus. Endotracheal intubation was needed in 29 and ventilatory support in 19 children. Most of the life support measures were required during the initial 48 hours. Nineteen (22%) children died, 16 of whom were comatose on admission. Multiple system involvement was associated with higher mortality. There were no deaths among the children who were not transferred to the PICU. Children with ABM who have a Glasgow coma score <8, clinical signs of raised ICP, refractory status epilepticus, shock and/or respiratory compromise should be prioritised to receive PIC.

Amongst organophosphate compounds, both pesticides and warfare neurotoxics are probably the most representative. These compounds are irreversible acetylcholinesterase inhibitors. Usual clinical signs observed after acute poisoning are mainly respiratory distress, convulsions and seizures. Following acute poisoning, an emergency treatment must be provided as soon as possible (maximum delay of 1 hour post-poisoning), to prevent irreversible brain damage and patient death. At the present time, there is no efficient delayed treatment which could be provided if this 1 hour latency is overpassed. However, neurogenesis by stem cell engraftment, eventually complemented by gene therapy strategy, could be a potential therapeutic approach to repair organophosphate-induced brain damage. Main stem cell engraftement strategies successfully used for brain damage of various origins are reviewed in this Article.

A neonate presenting to the emergency department can present a challenge to even the most experienced clinician. This article has focused on four deceiving and potentially devastating neonatal diseases. 1. Neonatal herpes is a potentially devastating illness without pathognomonic signs or symptoms. Early recognition and therapy can reduce mortality markedly. Although no specific sign or symptom is diagnostic,the diagnosis should be strongly considered in the presence of HSV risk factors, atypical sepsis, unexplained acute hepatitis, or focal seizure activity. Acyclovir therapy should be initiated before viral dissemination or significant CNS replication occurs. 2. Pertussis is a disease in which infants are at greatest risk of death or severe complication. Neonatal pertussis often presents in an atypical manner, lacking the classic signs and symptoms such as the "whoop."More common signs and symptoms include cough, feeding difficulty,low-grade fever, emesis, increasing respiratory distress, apnea, cyanosis,and seizures. Management should include hospitalization, supportive care, and antibiotics. 3. Congenital heart defects, particularly ductal-dependent lesions, may have an initial asymptomatic period that culminates in a rapidly progressive and fatal course. A neonate with CHD presents with shock refractory to volume resuscitation or pressor support. Resuscitative efforts are ineffective unless PGE, is administered. 4. Inborn errors of metabolism often are unsuspected because of their protean and heterogeneous nature. Signs and symptoms are subtle,are nonspecific, and often mimic other, more common diseases.An elevated index of suspicion, along with application and correct interpretation of a select few laboratory tests, is the key to making a diagnosis. Therapy is relatively straightforward and focused on resuscitation followed by prevention of catabolism and correction of specifically identified abnormalities. Although these disorders are relatively uncommon, prompt diagnosis and therapy can lead to a decrease in morbidity and mortality. The key is to maintain a high index of suspicion.
