Glucose disposal was studied in six very low birth weight infants (birth weight 1093 +/- 67 g (M +/- SEM), gestational age 29.8 +/- 0.6 weeks, postnatal age 5.2 +/- 0.9 days) by constant infusion steady state technique. All babies required artificial ventilation because of respiratory distress syndrome (four) or aspiration pneumonia (two). Nine healthy prematures of comparable birth weight, gestational age, and postnatal age formed the control group. During a constant glucose infusion at a rate of 8 mg/kg/min (7.7 +/- 0.2) mean blood glucose levels of the sick infants were higher than the corresponding control values. All sick babies had glycosuria (glucose excretion 34 +/- 19 mg/kg/hr compared to none of the controls 0.8 +/- 0.2, p less than 0.01). Glucose disposal in the sick prematures was significantly decreased in comparison to the healthy infants [92.6% (78.7 to 99.3%) of input rate vs. 99.8% (99.7 to 99.9%), p less than 0.01]. It is concluded that sick very low birth weight infants tend to develop hyperglycemia, glucosuria, impaired glucose disposal, and renal caloric wasting when exogenous glucose is supplied at a rate of 8 mg/kg/min, which is usually well tolerated by healthy prematures.

The dysphagia that occurs as an early sign of progressive supranuclear palsy (PSP), and which may predispose patients to aspiration pneumonia, has never been fully characterized. We evaluated 27 patients (mean +/- SEM: age, 64.9 +/- 1 years; symptom duration, 52 +/- 5 months) who met the clinical National Institute of Neurological Disorders and Stroke and Society for PSP (NINDS-SPSP) criteria for possible or probable PSP, with a swallowing questionnaire, an oral motor and speech examination, and either a modified barium swallow or ultrasound studies. Twenty-eight age- and sex-matched healthy controls (age, 65.6 +/- 1.5 years) were also evaluated with the questionnaire, oral examination, and the ultrasound study. We used ANOVA statistics to evaluate differences between groups; nonparametric correlations to assess associations between swallowing and motor and cognitive abnormalities; and logistic regression analysis to determine if the items of the questionnaire or oral examination predicted ultrasound or modified barium swallow abnormalities. While PSP patients had at least one complaint on the swallowing questionnaire (mean, 6.6), healthy controls had fewer and less relevant complaints (0.3). Patients with moderate-to-severe cognitive disabilities had significantly more complaints of dysphagia than those with mild or no impairment. PSP patients' oral motor skills and speech were mildly impaired but significantly different from those of controls. In the ultrasound studies, PSP patients had significantly fewer continuous swallows and required a longer duration to complete their swallows than did healthy controls. They also had mild-to-moderate abnormalities in the modified barium swallow study. The swallowing questionnaire, oral motor examination, and speech production examination accurately predicted the abnormalities detected with the swallowing studies. While 75% of patients had abnormal speech, all but one had abnormal swallowing studies. Thus, although dysphagia is associated with dysarthria, the two conditions are not always paired in the same patient. Our results suggest that the swallowing questionnaire and oral motor examination are an easy and cost-effective method to predict the swallowing disturbances in PSP.
