RESUMO
OBJECTIVE: Evaluation of the importance of pleuro-pulmonary involvement in paediatric patients with blunt splenic trauma. METHOD: A retrospective chart review of 27 patients, aged 2-16 years, treated for blunt splenic injury between 1992 and 1999 was performed. RESULTS: All patients except one were treated conservatively. In 12 patients (44.4%) left-sided pleuro-pulmonary involvement was diagnosed as primary traumatic injury or as a late complication. While Grade I and II splenic injuries were prevalent, pleuro-pulmonary involvement patients had a more severe degree of splenic injury. Chest pain, dyspnoea and diminished respiratory sounds were present on primary examination in patients with chest trauma. Body temperature during the first 5 post-trauma days was significantly higher among pleuro-pulmonary involvement patients. Specific pleuro-pulmonary involvement diagnoses on admission in six children with primary chest trauma were: lung contusion, pleural thickness, or haemo-pneumothorax. Three of them developed delayed pleural effusion. In the other six children with pleuro-pulmonary involvement, late complications appeared during 2-5 days post-trauma. CONCLUSIONS: Pleuro-pulmonary involvement was observed in almost half of patients with blunt splenic trauma. Pleuro-pulmonary involvement occurred either early as a result of direct chest trauma or was delayed. High suspicion, careful monitoring of body temperature and repeated chest X-ray studies are recommended for early diagnosis and treatment of delayed pleuro-pulmonary involvement.

Intestinal dysmotility and neurogenic bladder have been described as part of two autosomal-recessive mitochondrial disorders assumed to be due to a defect in communication between the nuclear and mitochondrial genomes: myoneurogastrointestinal encephalopathy (MNGIE) and diabetes insipidus, diabetes mellitus, optic atrophy, and deafness (Wolfram syndrome). Partial cytochrome c oxidase deficiency has been described in both. We describe three Ashkenazi Jewish siblings with progressive intestinal dysmotility, neurogenic bladder, and autonomic manifestations but no central nervous system involvement. Cytochrome c oxidase deficiency was demonstrated in peripheral and multiple intestinal muscle biopsies. Mitochondrial DNA analysis of an intestinal biopsy of patient 1 showed heteroplasmy consisting of a normal 16.5-kb band and an approximately 28-kb band, suggestive of a duplication. Mitochondrial DNA analysis of a muscle biopsy of patient 2 showed multiple deletions, mainly 10- and 11-kb bands. We suggest that this unique combination of intestinal pseudo-obstruction and neurogenic bladder could comprise a new autosomal-recessive mitochondrial disorder.
