[EX Q]: Abstract: Three patients with postcholecystectomy unilateral hepatic duct stricture and subsequent liver atrophy were treated conservatively, with a successful outcome of up to three years follow up. A better understanding of the pathophysiological sequelae of segmental hepatic duct obstruction suggests that in such circumstances reconstructive surgery, with its attendant risks, may not invariably be necessary.

[EX Q]: Abstract: To determine the systemic absorption of epinephrine when it is given by inhalation, six normal volunteers were given 15 puffs, followed by 30 puffs, of epinephrine from a pressurized aerosol (160 micrograms epinephrine/puff). The peak mean (+/- SE) plasma epinephrine levels were 1.50 (+/- 0.61) and 4.22 (+/- 1.93) nmol/L 1 minute after each dose, respectively. The effect on physiologic finger tremor correlated with the plasma epinephrine level and returned to baseline 20 minutes after taking the higher dose. There was a small fall in mean plasma potassium levels of 0.45 mmol/L and a small rise in plasma glucose levels of 0.81 mmol/L. On a separate occasion an injection of 0.3 ml of 1/1000 (300 micrograms) epinephrine was given subcutaneously to the same individuals. This caused a peak plasma epinephrine level of 2.43 (+/- 0.47) nmol/L at 10 minutes, and this was still raised at 2.05 (+/- 0.41) nmol/L after 40 minutes. The maximum fall in the mean plasma potassium level was 0.43 mmol/L after the injection.

[EX Q]: Abstract: A method is described to measure reproducibly stiffness, and therefore "tone", at the elbow of patients with Parkinson's disease using a torque motor. In Parkinsonian versus normal patients (previously reported) it was observed that: the neutral angle in Parkinson's disease patients was significantly smaller (92 degrees +/- 15 degrees) than in normals (107 degrees +/- 10 degrees), and in Parkinson's disease patients, even with relatively mild symptoms, the upper limb was stiffer than normals in the totally relaxed state with no electromyographic activity present. Our results suggest that changes in the passive mechanical properties of the upper limb affected by Parkinsonian rigidity may have taken place, accounting for the more flexed neutral elbow angle and greater passive stiffness. Using this technique, response to antirigidity therapy and natural progression of illness can be quantitatively assessed and followed.
