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.

Although there may be variable presentations depending on the stage and location of cysts in the nervous system, most children (> 80%) present with seizures particularly partial seizures. About a third of cases have headache and vomiting. Diagnosis is made by either CT or MRI. Single enhancing lesions are the commonest visualization of a scolex confirms the diagnosis. Some cases have multiple cysts with a characterstic starry-sky appearance. Management involves use of anticonvulsants for seizures and steroids for cerebral edema. The use of cysticidal therapy continues to be debated. Controlled studies have shown that cysticidal therapy helps in increased and faster resolution of CT lesions. Improvement in long -term seizure control has not yet been proven. Children with single lesions have a good outcome and seizure recurrence rate is low. Children with multiple lesions have recurrent seizures. Extraparenchymal NCC has a guarded prognosis but it is rare in children. In endemic areas NCC must be considered in the differential diagnosis of seizures and various other neurological disorders. [Indian J Pediatr 2009; 76 (5) : 537-545]

It is being widely tried as a targeted antispasticity treatment in children with cerebral palsy. A number of studies have shown that it reduces spasticity and increases the range of motion and is particularly useful in cases with dynamic contractures. However improvement in function has not been convincingly demonstrated. It is an expensive mode of therapy and the injections need to be repeated after 3-6 months. Whereas Botulinum toxin can be a valuable adjunct in select cases, it should not be projected as a panacea for children with spastic cerebral palsy.

MRI of the spine revealed an intramedullary tuberculoma at the level of C5-7. Investigations further revealed evidence of tuberculosis in the brain and lungs as well. The child made a rapid recovery with medical management alone.

The majority of cases usually occur in individuals with defective cell-mediated immunity, most commonly due to HIV infection. The authors here in report an 8-year-old girl from Nepal who presented with fever, cough, headache, lymphadenopathy, hepatosplenomegaly and cutaneous lesions. Lymph node biopsy revealed multiple granulomas composed of histiocytes and epitheliold cells along with numerous yeast forms of cryptococcus. Cultures of CSF, sputum and urine yielded cryptococcus neoformans. Surprisingly,the immune function in terms of T-cell number, CD4 : CD8 ratio, serum immunoglobulins and HIV serology was normal. After the diagnosis of disseminated cryptococcosis was established, the patient was treated with 5-fluorocytosine (100 mg/kg/day) for initial two weeks and amphotericin B (1 mg/kg/day) for 13 weeks. Patient responded well to the treatment with disappearance of presenting symptoms, cutaneous lesions, and lymphadenopathy, though she still had hepatosplenomegaly, which also decreased. Unfortunately, she developed loss of vision in 10th week of therapy. The patient was discharged on oral fluconazole (6 mg/kg/day) and no recurrence was found during the follow-up period of more than 9 months. This is the first case of disseminated cryptococcosis with no detectable immune deficit, from India.

There is scarcity of epidemiological data, required to plan services in resource constrained developing nations. To study the prevalence and treatment gap in childhood epilepsy in north Indian city, in the age group of 1-18 years. A two stage stratified cluster sampling; probability proportionate to size (PPS) was employed. A ten question screening questionnaire was employed to identify the presence of epilepsy. Definitions provided by International League against Epilepsy (ILAE) were used to classify screen positive subjects as epilepsy and to calculate the treatment gap. The prevalence rate for epilepsy was 6.24/1000 population. Febrile seizures and neurocysticercosis were most common causes of symptomatic seizures in childhood. This study of epidemiology of epilepsy provides valuable aid in optimizing effective community approach, thereby improving outcomes of childhood epilepsy.

The subjects were consecutive cases of children with a diagnosis of nonepileptic seizures (N=17, mean age = 10.7 years, S.D. = 1.26) and two groups of control groups matched on age and sex: true seizure group and healthy controls. All the children were recruited from the out-patient services of the Department of Pediatrics of a tertiary care teaching hospital in North India. Detailed history taking and clinical examination was done in the case of every child. A standard 18 channel EEG was done in all the children and a video EEG was done in 12 cases of children with nonepileptic seizures. The Childhood Psychopathology Measurement Schedule (CPMS) and Life Events Scale for Indian Children (LESIC) were used to measure the children's emotional and behavioral functioning at home, and the number of life events and the stress associated with these events in the preceding year and the year before that. Short-term outcome was examined three to six months after the diagnosis of nonepileptic seizures was made. Unresponsiveness without marked motor manifestations was the most common "ictal" characteristic of the nonepileptic seizures. Pelvic thrusting, upper and lower limb movements, head movements, and vocalization were observed in less than one-third of the patients. Increased psychosocial stress and significantly higher number of life events in the preceding year were found to characterize children with nonepileptic seizures, as compared to the two control groups. The nonepileptic seizures and true seizures groups had a higher proportion of children with psychopathology scores in the clinically significant maladjustment range, as compared to those in the healthy control group. A majority of the patients (82.4%) either recovered completely or had more than 50% reduction in the frequency of their symptoms, after three to six months of initiation of therapy. Psychosocial stress is common among children with nonepileptic seizures. Confirmatory diagnosis by video EEG, along with prompt psychosocial intervention, often results in a favorable outcome for most children with nonepileptic seizures.

Attributes favorable to sonography that make it almost indispensable for routine care of the newborn includes easy access, low cost, portability, lack of ionizing radiations and exemption from sedation or anaesthesia. Cranial sonography has highest impact in neonates suspected to have meningitis and its complications; perinatal ischemia particularly periventricular leukomalacia (PVL); hydrocephalus resulting from multitude of causes and hemorrhage. Not withstanding this, cranial sonography has yielded results for a repertoire of indications. Approach to cranial sonography involves knowledge of the normal developmental anatomy of brain parenchyma for correct interpretation. Correct technique, taking advantage of multiple sonographic windows and variable frequencies of the ultrasound probes allows a detailed and comprehensive examination of brain parenchyma. In this review, we discuss the technique, normal and v...

A retrospective evaluation of the pediatric patients with posterior reversible encephalopathy syndrome seen over the last 5 years in the authors' hospital was done. The magnetic resonance imaging (MRI) findings were analyzed, and a review of literature was performed. Out of 32 pediatric patients of posterior reversible encephalopathy syndrome, 10 (31.25%) were males and 22 (68.75%) were females, with a mean age of 10.6 years. Renal disease (62.5%) was the most common primary disease, followed by chemotherapy for hemato-oncologic malignancies (15.6%). Hypertension was present in 81.2% of cases. Atypical MRI findings were seen in 62.5% cases. Frontal involvement was common and seen in 56% of the cases. Overall, MRI findings considered atypical in adults were found to be common in the series of pediatric posterior reversible encephalop...

The confirmed diagnosis is based collectively on radiological findings and serodiagnostic techniques. The serodiagnostic techniques have variable sensitivity and specificity depending upon the technique, antigens used, location and number of cysts. Crude soluble extract (CSE), excretory secretory (ES) and lower molecular mass (LMM) (10-30 kDa) antigenic fraction of T. solium cysticerci were evaluated for antibody detection in serum and urine samples by ELISA. Serum and urine samples were collected each from 125 clinically suspected and radiologically proven NCC (111 with single Computed Tomography (CT) lesions and 14 with multiple CT lesions) and 125 control subjects (60 with neurological disorders other than NCC, 40 with other parasitic diseases and 25 apparently healthy subjects). The sensitivity of the ELISA with the use of CSE, ES and LMM antigenic fractions was 38.4%, 63.2% and 30.4% with serum (cut off dilution 400), 46.4%, 44% and 47.2% with neat urine and the specificity was 88%, 76.8% and 85.6% with serum (cut off dilution 400), 66.4%, 65.2% and 58.4% with neat urine samples, respectively. The study suggests that detection of antibody to ES antigen in serum samples may serve useful purpose for the serodiagnosis of human NCC.

Total body water (TBW), extracellular water (ECW) and urinary and serum sodium and osmolality were estimated on the day of hospitalization (Day 1) and after recovery/Day 10. Thirty age- and sex-matched children served as their controls. The TBW (683 +/- 63 (mean +/- SD) ml/kg) as well as ECW (311 +/- 76 ml/kg) was significantly higher in children with meningitis on Day 1 than in the controls (TBW 642 +/- 49 ml/kg, ECW 271 +/- 62 ml/kg) (P < 0.01), whereas the values after recovery (TBW 643 +/- 48 ml/kg, ECW 272 +/- 63 ml/kg) were similar to those of controls. Thus on the average a child with acute meningitis had excess body water, all of which was in the ECW compartment. The mean ECW excess was 33 +/- 32 ml/kg. Twenty-four of 27 surviving children had higher TBW and ECW at the time of admission compared with the values after recovery. On multiple regression analysis, the only significant determinant of ECW excess was severity of the illness (partial r2 = 0.62). The ECW excess was 70 +/- 8 ml/kg in severely ill, 50 +/- 32 ml/kg in moderately ill and only 12 +/- 18 ml/kg in mildly ill children (P < 0.01). Those who had complications or sequelae had much higher ECW (49 +/- 26 ml/kg) than those who recovered completely (17 +/- 27 ml/kg).(ABSTRACT TRUNCATED AT 250 WORDS)

All had a history of trauma and associated neurologic deficit which gave clue to the diagnosis. The authors present a child who presented with a massive, rapidly filling, clear pleural effusion in whom there was no neurologic deficit. The history of an automobile accident in the past had almost been forgotten. A subarachnoid-pleural fistula was discovered on exploratory thoracotomy. The entity should be thought of, and actively investigated, in a child with a history of trauma and a pleural effusion of obscure etiology, even if there is no associated neurologic deficit.

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.
