Changing trend of SSPE over a period of ten years.

Sub acute sclerosing pan-encephalitis (SSPE) is a slowly progressive inflammatory disorder of the central nervous system. A decline in frequency has been noticed in most of the developed countries, whereas it continues to be high in developing countries. Though a number of studies have been carried out, the exact trend of SSPE is still not clear. Hence the present study was carried out to analyze the trend of SSPE over the past ten years in and around Chandigarh. A total of 205 patients with clinical features suggestive of SSPE were enrolled for the study during Jan'92 to Dec. 2001. Measles specific antibodies were detected in blood and CSF by HAI method. 114 patients were found to be positive for measles specific HAI antibody with a male preponderance. The number of SSPE cases were found to be more during the period 1992-95 in comparison to the next 6 years (p < 0.05). The high incidence of SSPE in our country could be due to improper vaccine coverage, poor cold chain maintenance or circulation of atypical measles virus strain.

Shaken baby syndrome masquerading as apparent life threatening event.

A variety of diseases and disorders can present as an acute life-threatening event among which shaken baby syndrome has been recently recognized. A high index of suspicion along with an ophthalmologic evaluation and cranial imaging helps to identify this form of child abuse, which needs multidisciplinary management.

Folic acid and phenytoin induced gingival overgrowth--is there a preventive effect.

The role of folic acid (5mg/day) in combination with oral hygiene measures (group II) vis-a-vis oral hygiene measures alone (group I) in prevention of phenytoin-induced gingival overgrowth was investigated in a one-year follow-up study on sixty, 8-13-year-old epileptic children receiving phenytoin. The allocation of the children to the two groups was done alternately. In these children, at baseline, plaque (Silness & Löe), gingivitis (Löe & Silness) and probing depths of gingival sulcus were recorded. These parameters were re-evaluated at 3-monthly intervals when gingival overgrowth was also recorded (Modified Harris & Ewalt Index). It was seen that, after a period of one year, gingival overgrowth occurred in 60 and 50 percent children of groups I & II respectively and its development, too, was delayed in group II. More cases (93 percent) in group II exhibited minimal overgrowth as against 78 percent in group I. The study concluded that systemic folic acid prescribed along with phenytoin delays the onset and reduces the incidence and severity of gingival overgrowth induced by phenytoin.

Cerebral gigantism with West syndrome.

A case of cerebral gigantism (Sotos syndrome) with West syndrome in a one-year-old male child is reported. The case had a large stature, typical facies and neurodevelopmental delay along with infantile spasms, which were refractory to treatment with valproate and clonazepam.

Incidence of phenytoin induced gingival overgrowth in epileptic children: a six month evaluation.

Thirty children aged 8-13 years with epileptic disorders and receiving mono-drug therapy with Phenytoin, were selected from the Departments of Pediatrics and Neurology of PGIMER, Chandigarh to evaluate the development of gingival overgrowth induced by phenytoin over a period of six months. These children were evaluated at baseline at three monthly intervals for a period of six months for plaque (Silness and Loe, 1964), gingivitis (Loe and Silness, 1963) and probing depth of the gingival sulcus. Gingival overgrowth was noted as and when it developed using modified version of Harris and Ewalt Index, 1942. No attempt was made to modify the childrens' prevailing oral habits. The results indicated that gingival overgrowth in 57% of the children was in the mesio-distal dimension of the gingival papillae and occurred within six months of initiation of therapy with Phenytoin.

Bacterial meningitis in children: critical care needs.

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.

Diagnosis and management of children with attention deficit hyperactivity disorder.

Attention deficit hyperactivity disorder (ADHD) is one of the most prevalent childhood psychiatric disorder which is characterized by three core symptoms of inattention, hyperactivity and impulsivity. It is estimated that 5% to 10% of school aged children suffer from this disorder. This disorder is more common in boys than girls. Comorbidity is a major problem and is present in as many as two thirds of children with ADHD. A multiple modality approach to treatment which combines pharmacotherapy, psycho education, behaviour therapy, environmental changes and social skills training is recommended. The outcome of ADHD is variable and unless properly treated in early years may predispose the child to serious psychopathology in adulthood.

The child with cerebral palsy--clinical considerations and management.

Cerebral Palsy (CP) is a non-progressive disorder of the motor system secondary to brain injury during early development. Associated non-motor problems are frequent and contribute significantly to the disability. While spastic CP is the commonest, dyskinetic CP continues to be a problem in our contribute. Acquired CP mostly secondary to CNS infections constitutes a significant proportion of cases in developing countries. Early diagnosis, proper assessment of the functional capacity and needs of the child and providing early intervention are important. A multidisciplinary approach to management with active parental involvement helps the child achieve his potential.

Newer antiepileptic drugs and non surgical approaches in epilepsy.

Newer antiepileptic drugs (AEDs) have helped the management of about one third of children with epilepsy who are refractory to primary AED(s). Vigabatrin and lamotrigine are being used as first line drugs for infantile spasms and Lennox Gestaut syndrome (LGS) respectively. Most of the others are, as of now, used as add-on drugs with specific indications. The ketogenic diet has been used successfully in some children with LGS. Steroids have a clear role in infantile spasms. Efficacy of immunoglobulins is mainly anecdotal. Physicians should familiarise themselves with the efficacy, pharmacokinetics and side effects of these drugs and ensure their rational use.
