Hemophilia a and spinal epidural hematoma in children.

Hemophilia A is an X-linked bleeding disorder, caused by deficient or defective blood coagulation factor VIII. The most characteristic symptoms of the severe forms of hemophilia A are joint and muscle bleeds. Intracranial hemorrhage occurs only in 3-10% of the patients. Spinal epidural hematomas are rarely seen. We describe a 13-month-old boy with hemophilia A who was admitted to the hospital because of irritability and unspecified pain for the past two days. There was no history of evident trauma, no fever. Physical investigation showed no skin lesions or hematomas and no obvious cause for the pain. Neurological examination showed a dysphoric toddler, mainly in the fetal position. No neurological abnormalities were found except for a miosis of the right pupil due to a suspected Horner syndrome. Magnetic resonance imaging of the spine showed an extensive epidural hematoma. The boy was successfully treated with intensive replacement therapy during three weeks and did not require surgical intervention. There was a rapid and complete clinical resolution. In conclusion, rare hematomas should be considered and searched for in children with bleeding disorders and not well understood complaints. Early diagnosis is important for the neurological outcome.

Seasonality of long term wheezing following respiratory syncytial virus lower respiratory tract infection.

BACKGROUND: It is well known that respiratory syncytial virus (RSV) lower respiratory tract infection (LRTI) is associated with subsequent wheezing episodes, but the precise natural course of wheezing following RSV LRTI is not known. This study aimed to determine the continuous development of wheezing following RSV LRTI in children up to the age of 3 years. METHODS: A prospective cohort study was performed in 140 hospitalised infants with RSV LRTI. Continuous follow up data were obtained with a unique log in which parents noted daily respiratory symptoms. RESULTS: A marked decrease in wheezing was seen during the first year of follow up. The burden of wheezing following RSV LRTI was observed during the winter season. Signs of airflow limitation during RSV LRTI were strongly associated with wheezing during the follow up period. Total and specific serum immunoglobulin E levels, patient eczema, and parental history of atopy were not associated with wheezing. CONCLUSIONS: Airway morbidity following RSV LRTI has a seasonal pattern, which suggests that viral upper respiratory tract infections are the predominant trigger for wheezing following RSV LRTI. There is a significant decrease in airway symptoms during the first 12 months after admission to hospital. Simple clinical variables, but not allergic risk factors, can predict the development of wheezing following RSV LRTI.
