A retrospective study was performed to determine the clinical and pathologic features, etiology, and outcome of children with the reversal sign. The reversal sign, a striking CT finding, probably represents a diffuse, anoxic/ischemic cerebral injury. CT features of the reversal sign are diffusely decreased density of cerebral cortical gray and white matter with a decreased or lost gray/white matter interface, or reversal of the gray/white matter densities and relatively increased density of the thalami, brainstem, and cerebellum. Twenty children with the reversal sign were retrospectively analyzed. We divided the patients into three groups: (1) acute reversal, (2) intermediate group, and (3) chronic reversal. There were nine cases of trauma (seven of child abuse); nine hypoxia/anoxia incidents (birth asphyxia, drowning, status epilepticus); one bacterial meningitis; and one degenerative encephalitis. All acute- and intermediate-group patients had respiratory problems requiring ventilator support and intensive care. In five of seven patients who died, autopsy findings were consistent with anoxic/ischemic encephalopathy. Surviving patients have profound neurologic deficits with severe developmental delay. The CT reversal sign carries a poor prognosis and indicates irreversible brain damage.

We reviewed the medical records of 218 episodes of status epilepticus in 193 children who were admitted to the hospital between 1983 and 1987. Of the episodes, 61% were in boys and 39% in girls, with an age range of 1 month to 14 years (average, 3.2 years). The majority of episodes (73%) occurred in patients who were less than 5 years old, with 61% less than 3 years old and 28% less than 1 year old. Status epilepticus as the initial seizure occurred in 71% of episodes. In patients under 1 year of age, 75% of episodes were associated with acute causes (bacterial meningitis in 28% and electrolyte disorders in 30%), and 23% were idiopathic (19% associated with fever). In children less than 3 years old, 47% of episodes had an acute cause, 9% had a previously known seizure disorder, and 32% were idiopathic (30% associated with fever). In patients older than 3 years, 28% of episodes were associated with acute causes, 38% were known epileptics, and 13% were idiopathic (11% had fever). Overall mortality was 6%, with 1% of all episodes ending in death during the presenting seizure. We conclude that the etiology of status epilepticus is age related, with acute causes being more common in patients with a younger age at presentation. When our data are compared with other large studies in children, it appears that mortality associated with status epilepticus has decreased.

To determine the importance of intracranial hypertension in central nervous system acute infections, we studied intracranial pressure (ICP) in 27 patients, aged 45 days to 13 years. Fourteen had meningitis and 13 had encephalitis; all were in deep coma with a Glasgow Coma Scale 7 or less. Intracranial hypertension defined by a mean ICP above 15 mm Hg was observed in 12 patients with meningitis (86%) and in 9 with encephalitis (69%). Patients with meningitis exhibited a very early and severe intracranial hypertension. A striking difference is noted between survivors and non-survivors who had a very high maximal ICP with a severe reduction in cerebral perfusion pressure. Intracranial hypertension occurred in all patients with acute primitive encephalitis but only in 3/7 patients with post-infectious encephalitis. ICP monitoring seems to be important in the comatose forms of bacterial meningitis in the early period, herpes encephalitis and postinfectious encephalitis with severe status epilepticus.

To determinate the importance of intracranial hypertension in central nervous system (CNS) acute infections, we studied intracranial pressure (ICP) in 27 patients, age 45 days to 13 years. Fourteen had meningitis and 13 had encephalitis; all were in deep coma with Glasgow Coma Scale 7 or less. Intracranial hypertension defined by a mean ICP above 15 mmHg, was observed in 12 patients with meningitis (86%) and in 9 with encephalitis (69%). Patients with meningitis exhibited a sudden and severe intracranial hypertension. A striking difference was noted between survivors and non survivors who had a very high maximal ICP with a severe reduction of cerebral perfusion pressure (CPP). Intracranial hypertension occurred in all patients with acute primary encephalitis but in only 3/7 patients with post-infectious encephalitis. ICP monitoring seems to be important in the comatose forms of: (1) bacterial meningitis in the early period (2) herpes encephalitis (3) post-infectious encephalitis with severe status epilepticus.

Acute bacterial meningitis (ABM) in children is associated with a high rate of acute complications and mortality, particularly in the developing countries. Most of the deaths occur during first 48 hours of hospitalization. Coma, raised intracranial pressure (ICP), seizures, shock have been identified as significant predictors of death and morbidity. This article reviews issues in critical care with reference to our experience of managing 88 children with ABM in PICU. Attention should first be directed toward basic ABCs of life-support. Children with Glasgow Coma Scale (GSC) score < 8 need intubation and supplemental oxygen. Antibiotics should be started, even without LP (contraindicated if focal neuro-deficit, papilledema, or signs of raised ICP). Raised ICP is present in most of patients; GCS < 8 and high blood pressure are good guides. Mannitol (0.25 gm/Kg) should be used in such patients. If there are signs of (impending) herniation short-term hyperventilation is recommended; prolonged hyperventilation (> 1 hour) must be avoided. Any evidence of poor perfusion, hypovolemia and/or hypotension needs aggressive treatment with normal saline boluses and inotropes, if necessary, to maintain normal blood pressure. Empiric fluid restriction is not justified. Seizures may be controlled with intravenous diazepam or lorazepam. Refractory status epilepticus may be treated with continuous diazepam (0.01-0.06) mg/kg/min) or midazolam infusion. Ventilatory support may be needed early for associated pneumonia, poor respiratory effort and/or coma, and occasionally to reduce work of breathing in shock. Provision of critical care to children with ABM may reduce the mortality significantly as experienced by us.

Ceftriaxone is recommended in children with acute bacterial meningitis (ABM) for 10 days. However, the drug is expensive, and shorter duration of therapy, if equally effective, would cut costs of therapy and hospitalization. The aim of this study was to compare the outcome of 7 days vs. 10 days' ceftriaxone therapy in children with ABM. Seventy-three children aged 3 months to 12 years with ABM, consecutively admitted to hospital were enrolled. Ceftriaxone was given for 7 days to all. Randomization to group I (7 days) and group II (10 days) therapy was done on the seventh day. At the end of 7 days' therapy in group I and 10 days in group II, children were evaluated using a clinical scoring system. Children with a score of more than 10 were labelled as 'treatment failures' and were continued on ceftriaxone. If a score was less than 10, the antibiotic was stopped. Complications were appropriately evaluated and managed. All children were followed-up 1 month after discharge: neurodevelopmental assessment, Denver Development Screening Tests, IQ and hearing assessment were done. After excluding four patients, there were 35 children in group I and 34 in group II. The two groups were comparable with respect to age, sex, nutritional status, presenting clinical features, and CSF parameters. Organism identification was possible in 38 per cent of children: (Streptococcus pneumoniae, 21 per cent; Haemophilus influenzae, 13 per cent; meningococcus, 4 per cent). Treatment failure rate was comparable in both groups (9 in group I and 8 in group II) as was the sequelae at discharge and at 1 month (9 in group I, 15 in group II,p > 0.1). Status epilepticus and focal deficits at presentation were significantly associated with treatment failures and sequelae in both the groups (p < 0.05). Length of hospital stay was shorter in group I (10.8 +/- 6.0 days) as compared with group II (14.4 +/- 7.2 days,p < 0.05) and frequency of nosocomial infection was significantly more in group II (p < 0.05). It was concluded that clinical outcome of patients treated with 7 days' ceftriaxone therapy is similar to that of 10 days' therapy, and is associated with lesser nosocomial infection and earlier hospital discharge. Seven days ceftriaxone therapy may be recommended for uncomplicated ABM in children in developing countries.

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.

A 37-year-old man in a status epilepticus due to meningitis was admitted to Intensive Care because of respiratory insufficiency. Spinal fluid culture yielded Streptococcus salivarius. Despite extensive diagnostics, the source of this bacterium could not be found. However, the patient had recently undergone spinal anaesthesia for surgery on a toe ulcer, from which other bacteria were cultured. The patient died 2 weeks after admission with a picture of multiple organ failure. Bacterial meningitis following spinal anaesthesia may be the result of impairment of the blood-brain barrier due to a sudden drop of spinal fluid pressure during the puncture, or of the introduction of bacteria from the hair follicles or from a haematoma caused by the needle or the introducer. Hygienic measures and a proper technique when performing regional anaesthesia are important in preventing the dissemination of bacteria.

Infections of the central nervous system are a frequent cause for admission to the intensive care unit (ICU). These infections can be the reason for presentation to a hospital or a complication of an injury or surgical procedure. Diagnosing these infections can be very challenging, given the relative paucity of tests with high sensitivity and specificity. Regardless, identifying and treating the underlying cause remains the primary objective in each of these cases, but management of complications is the most common reason for ICU admission. Frequent complications include increased intracranial pressure, stroke, coma, and status epilepticus. Although the underlying infection often causes harm, the immune response to the agent and ensuing complications are often responsible for greater damage to the host. Even if the underlying infectious agent does not have a specific therapy, identifying it is important for limiting unnecessary testing. When certain infections are suspected, such as bacterial meningitis or viral encephalitis, empiric therapy should be initiated immediately. Outcomes for these conditions are linked to how quickly appropriate therapies are initiated.
