[Q]: Abstract: Patients with essential hypernatremia maintain urinary concentrating ability despite plasma hyperosmolality and low plasma vasopressin concentrations. We investigated renal sensitivity to ultralow dose vasopressin infusions in two patients with a syndrome of hypodipsia, hypernatremia with selective osmoreceptor dysfunction, early puberty, and aggressive behavior. The patients were water loaded until a hypotonic diuresis was established. Vasopressin was infused in stepwise increments from 0.4-12 fmol/kg X min. Both patients had increased renal sensitivity to vasopressin, achieving negative free water clearance at infusion rates of 0.4 and 4 fmol/kg X min (normal greater than or equal to 6). Treatment for 3 months with 1-desamino-8-D-arginine vasopressin (DDAVP) led to an improvement in behavior and the reporting, for the first time, of a sensation of thirst. After DDAVP therapy both patients had a reduction of their renal sensitivity to infused vasopressin. We conclude that untreated patients with essential hypernatremia have increased renal sensitivity to vasopressin which is reduced by DDAVP administration.

[Q]: Abstract: To study the relationship between lung weight and lymph flow, we used an in situ, isolated sheep lung preparation that allowed these two variables to be measured simultaneously. All lungs were perfused for 4.5 h at a constant rate of 100 ml X min-1 X kg-1. In control lungs, the left atrial pressure (Pla) was kept at atmospheric pressure. In experimental lungs, Pla was kept atmospheric except for a 50-min elevation to 18 mmHg midway through the perfusion. During this period of left atrial hypertension, pulmonary arterial pressure rose from 18 to 31 mmHg, lymph flow rose from 3 to 12 ml/h, and the lymph-to-plasma oncotic pressure ratio (pi L/pi P) fell from 0.7 to 0.48. After left atrial pressure was returned to control, pulmonary arterial pressure, lymph flow, and pi L/pi P all returned to control levels. The rate of weight gain after the return of left atrial pressure to control was also the same as that in the control group. However, during the period of left atrial hypertension 135 ml of fluid were filtered into the lung, and this large increase in lung weight remained after the pressure was lowered. The presence of this substantial excess lung water despite control values for vascular pressures, lymph flow, rate of weight gain, and pi L/pi P suggests that the absolute amount of lung water has little influence on the dynamic aspects of lung fluid balance. These results are consistent with a two-compartment model of the interstitial space, where only one of the compartments is readily drained by the lymphatics.

[Q]: Abstract: Twenty-three patients with idiopathic scoliosis were tested for upper extremity proprioceptive function. All subjects had documented progression of deformity, with an average curvature of 34 degrees. The average ages for scoliotics and 18 control subjects were 16.1 and 20.8 years, respectively. Controls had no spinal deformity and underwent identical test procedures. The test results showed that scoliotic subjects had significant asymmetry between right and left limbs in their threshold for detection of joint motion (p less than or equal to 0.005) and in their ability to reproduce angles to which their elbow joint had been previously positioned (p less than or equal to 0.025). Slight asymmetry also was observed in the reproduction tests of the control group (p less than or equal to 0.013); however, there was no significant asymmetry seen in this group for the threshold test. Performance of bilateral limbs was designated good and bad for both groups; the limb that performed better in proprioceptive function was designated good limb. Analysis of data showed that the scoliotics' good and bad limbs performed inferiorly in both threshold and angle reproduction tests when compared with normal controls. The results of this study imply, but do not localize, a neurologic deficit in scoliotic patients.
