A scoring system for lung function tests in infants.

Measurements of thoracic gas volume (TGV), airway resistance (Raw), and airway conductance (Gaw) were calculated in a group of 42 normal infants using a whole-body plethysmograph. Maximum expiratory flow at functional residual capacity was measured in a separate group of 108 normal infants. Using data obtained from these infants the following regression equations were calculated: Gaw (L.s-1.cmH2O) = -0.0475 + 0.00164 x length (cm) square root of TGV (mL1/2) = -3.22 + 0.263 x length (cm) VmaxFRC (mL.s-1) = -173 + 5.2 x length (cm). The standard errors of prediction are a measure of the scatter of individual results from the normal population about the true regression line. They were used to define limits of the normal ranges for these tests of lung function, and to develop a scoring system. This approach is preferable to expressing results as percent predicted, which gives no indication of how likely a measurement is to be within normal limits.

Syncope as a presenting feature of hindbrain herniation with syringomyelia.

Syncope is rare as a presenting symptom of syringomyelia. Three cases are described in which syncope brought the patient to hospital and in each case syringomyelia was subsequently diagnosed and treated. The suggestion is made that impaction of hindbrain hernia or the Chiari malformation may be a causative mechanism of loss of consciousness in such cases; the three examples presented all did well after posterior fossa surgery to decompress the hindbrain hernia.
