Neurofibromatosis type 1 growth charts.

Growth abnormalities such as macrocephaly and short stature have been described and are considered a consistent finding in neurofibromatosis type 1 (NF1), one of the most common autosomal dominant disorders in man. We present here a clinical study on the growth profile of a sample of NF1 patients collected through a population-based registry that covers three contiguous regions of North-East Italy (NEI-NF Registry). Auxometric traits of 528 NF1 patients have been measured with the aim of drawing growth charts for height, weight, and head circumference (OFC). Height velocity charts were based on a subset of 143 children who underwent multiple measurements. No differences in height were apparent between NF1 and normal subjects up to age 7 (girls) and 12 (boys) years; subsequently, the 50th centile of NF1 subjects tends to overlap with the 25th centile of normal subjects, and the 3rd centile is much lower in NF1 subjects than in normal subjects, mainly during adolescence. The negatively skewed distribution of height seems to indicate that height growth impairment affects only a proportion of NF1 subjects; height growth impairment does not seem related to disease severity. As for weight, our data suggest that slight overweight is a characteristic of adult NF1 subjects (mainly among males), independent of disease severity. Height growth velocity is normal during childhood for both sexes, whereas the pubertal spurt is slightly anticipated and reduced in NF1 boys but not in girls. Our data confirm previous observations that macrocrania affects most NF1 subjects; the shape of the head growth curve is similar in NF1 and normal girls, whereas NF1 boys present an OFC pubertal growth spurt much more pronounced and delayed than normal boys. The disproportion between OFC and height seems to be related to disease severity in boys but not in girls. Growth charts presented here can be useful in neurofibromatosis clinics for the identification of the effects of secondary growth disorders, for growth prognosis, and for the evaluation of the effects of a therapy such as GH therapy after radiotherapy for optic glioma

Use of Urokinase in childhood pleural empyema

Urokinase is an enzyme with a fibrinolytic effect that facilitates pleural empyema drainage through a chest tube. The aim of this study was to assess the risk of pneumothorax, the need for pleural debridement surgery, the persistence of fever, and the number of days in hospital in a group of children with parapneumonic pleural empyema treated with urokinase. This was an uncontrolled retrospective study on children suffering from parapneumonic empyema. Data collected on 17 children treated with urokinase were compared with 11 children treated prior to the advent of urokinase (the "historic" group). The urokinase was instilled in the pleural cavity over a period ranging from 2-8 days, amounting to a median total dose per kilogram of body weight of 18,556 IU (range, 7,105-40,299). Surgical treatment of the empyema involved drainage tube placement and/or debridement of the pleural cavity. Three children developed pneumothorax during their hospital stay, and one more case occurred 6 months after the child had recovered from his empyema; there were 3 cases of pneumothorax during the acute phase in the "historic" group (P = 0.54). Five children in the urokinase group were debrided and 12 were only drained, as opposed to 9 and 2, respectively, in the "historic" group (P = 0.02). The overall hospital stay was 17 days for the urokinase group, and 24 for the "historic" group (P = 0.02). No bleeding or other major complications were reported in the group treated with urokinase. In conclusion, urokinase treatment does not carry a risk of pneumothorax, while it does reduce hospital stay and the need for pleural debridement
