Nedocromil sodium for chronic asthma in children.

BACKGROUND: Currently inhaled corticosteroids are the main stay in the maintenance treatment of chronic asthma in children. Although inhaled corticosteroids play a crucial role in the management of childhood asthma, the long-term side effects of inhaled corticosteroids used in the management of chronic asthma in children are not clearly known. OBJECTIVES: The objective of this review is to compare the safety and efficacy of inhaled nedocromil sodium with placebo in the treatment of chronic asthma in children. SEARCH STRATEGY: We searched the Cochrane airway group trials register, Cochrane controlled trials register, Current contents, review articles, reference lists of articles. We also contacted the drug manufacturer and primary authors for additional citations. We also searched abstracts of major respiratory society meetings. The last search was carried out in October 2004 SELECTION CRITERIA: Randomised placebo controlled trials comparing nedocromil sodium to placebo in the treatment of chronic asthma in children (0 to 18 years). DATA COLLECTION AND ANALYSIS: Both authors independently assessed trial quality and extracted data. Study authors were contacted for additional information. MAIN RESULTS: Fifteen trials (twelve parallel group studies; three crossover trials recruiting 1422 children (837 males and 585 females)) were included. The studies were generally of good methodological quality. Two large long term studies used nedocromil for six months and four to six years and showed conflicting results in symptom free days. Short term studies (duration between 4 weeks to 12 weeks) showed that nedocromil sodium produced some improvement in a number of efficacy measures compared to placebo including FEV(1), FVC, FEV(1) % predicted, PC20 FEV(1), evening PEF and symptom scores. The parent's assessment of efficacy was in favour of nedocromil (odds ratio (OR) 0.5 (95% CI 0.3 to 0.8). Nedocromil sodium has a good safety profile. The only significant side effect observed was unpleasant taste. There was little evidence for a clinically dose response effect and only a few studies recruited participants with severe asthma. AUTHORS' CONCLUSIONS: A limited number of small studies have shown that nedocromil is of benefit in improving lung function and some measures of symptoms, but the evidence with regard to the primary outcome of the review was conflicting. Two long-term trials did not show consistent effects on lung function outcomes, whereas several small short-term trials have shown benefit in these outcomes. Differing severities at baseline may explain this difference with milder participants experiencing less benefit, although the discrepancy between study findings may also reflect publication bias. Nedocromil sodium is associated with a very good safety profile with no significant short term or long- term adverse side effects. Although nedocromil may have advantages over inhaled corticosteroids in terms of side effects, there is a need for head to head trials of nedocromil and inhaled corticosteroids to establish whether asthma control is similar, especially in mild asthma. It is not yet clear where nedocromil should sit in relation to other therapies in the treatment of asthma in children.

Peripheral neuropathy--a rare complication of paediatric systemic lupus erythematosus.

Peripheral neuropathy is an uncommon complication in paediatric systemic lupus erythematosus (SLE). We report the case of a 10-year-old Chinese girl who developed peripheral neuropathy within 3 months of the onset of SLE and presented with bilateral foot drop and sensory symptoms of both hands and feet. There was no involvement of the central nervous system at the time of presentation. The patient was negative for anticardiolipin antibodies, but positive for lupus anticoagulant. She was treated with intravenous methylprednisolone followed by oral steroids, methotrexate, gabapentin and amitryptyline. Although peripheral neuropathy is a rare complication of paediatric systemic lupus erythematosus, one should be vigilant for this entity as part of the neurological spectrum. It may not be associated with involvement of the central nervous system. Antiphospholipid antibodies may have role in the pathogenesis of SLE associated peripheral neuropathy. We speculate that routine nerve conduction studies may have a role in detecting sub-clinical cases.

Late presenting congenital diaphragmatic hernia.

Delayed herniation of the abdominal contents through a congenital diaphragmatic hernia may occur beyond the neonatal period. The case is reported of a 9 month old child presenting with acute respiratory distress secondary to tension gastrothorax. The chest radiograph showed a tension gastrothorax. Nasogastric tube placement confirmed herniation of the stomach into the left chest and is the initial treatment of choice when a tension gastrothorax is identified. The late presenting congenital diaphragmatic hernia poses considerable diagnostic challenges often leading to misdiagnosis and risk of thoracocentesis. The possibility of late presenting congenital diaphragmatic hernia should be considered in unusual cases of pneumothorax, especially in the absence of trauma so that unnecessary procedures like chest tube drainage can be avoided.

Papillary fibroelastoma of the tricuspid valve presenting as neonatal pulmonary haemorrhage.

UNLABELLED: Papillary fibroelastoma is a benign tumour of the cardiac valve apparatus. We present an unusual case of life-threatening pulmonary haemorrhage and disseminated intravascular coagulation in a neonate associated with this benign cardiac tumour. Papillary fibroelastoma of the tricuspid valve rarely presents in children and, to our knowledge, this is only the second reported case in a neonate. The patient was successfully managed by anticoagulation therapy followed by surgical excision of the tumour. This case illustrates the potentially fatal presentation of this benign cardiac tumour among neonates. CONCLUSION: Pulmonary haemorrhage of this degree is unusual in an otherwise healthy term neonate and needs careful investigation for unusual pathology including potential sources of pulmonary emboli in the heart. We emphasize the value of echocardiography in the evaluation of unexpected pulmonary haemorrhage in the newborn.
