The effect of diet and fasting on gallbladder opacification during oral cholecystography in dogs as measured by computed tomography.

To determine the influence of diet and fasting on gallbladder opacification during oral cholecystography, 10 dogs were studied in a blind, random fashion, giving single or two consecutive doses of iopanoic acid, sodium tyropanoate, or sodium ipodate while the animals were fasting, on a normal diet, or on a low-fat diet. Gallbladder density was determined by CT to eliminate the bias created by subjective interpretation of radiographs. For maximum, first-dose gallbladder opacification during clinical cholecystography, iopanoic acid should be given with a meal and sodium ipodate while the patient is fasting; diet makes no difference with sodium tyropanoate. For maximum opacification with two consecutive doses, iopanoic acid may be given with a meal or during fasting, while sodium ipodate and sodium tyropanoate should be administered during fasting.

Thoracic kyphosis: range in normal subjects.

Thoracic kyphosis was measured on chest radiographs of 316 "normal" subjects by means of a modification of the Cobb technique for measuring scoliosis. Patients were accepted as "normal" if they had no thoracic or spinal complaints or radiographic abnormalities in the chest including the thoracic spine. A total of 159 males and 157 female subjects 2-77 years old was studied. The relation among age, gender, and kyphosis were determined using least squares fits of first-order linear mathematical models. These results were also used to determine the expected ranges of kyphosis for a "normal" patient of a given age and gender. The degree of kyphosis increased with age and the rate of increase was higher in females than in males. Clinical explanations for this differential increase are discussed.
