“…Doubts have occasionally been expressed on the long-term safety of talc, mainly in relation to possible asbestos contamination; cosmetic talc is now subjected to x-ray diffraction and other quality control tests to ensure freedom from detectable asbestos.' Foreignbody granuloma is a theoretical risk, even with pure talc, but is not known to constitute a hazard with cosmetic talc in practice; a recent study2 showed minimal levels of respirable talc particles during normal use, the highest level being [1][2][3][4][5][6][7][8][9] The ionised calcium in the blood influences the action of the heart. The buffering capacity of the blood for calcium is such that slight increases in intake do not affect the ionised moiety.…”

In a retrospective survey performed to assess the reliability of ultrasound of the gall bladder in a district hospital the radiologists performing the examinations had little or no previous experience in non-obstetric ultrasound. In 142 patients who had the presence or absence of gall stones proved by surgery gall stones had been correctly predicted in 84% of patients with stones and absent in 64% of those without. This compares favourably with earlier reports from North America, and shows that ultrasound of the gall bladder is useful, even when staff experience is limited.

“…which were diagnosed by ultrasonographic and oral cholecystography [8], We used gallbladders from male patients only in order to avoid the hor monal fluctuation that normally occurs in women. Sixteen patients (mean age 56 ± 14.15 years) had radiolucent gallstones and 9 patients (mean age 54.44 ± 9 .7 3 years) had radiopaque ones.…”

Twenty-five gallbladders were studied in vitro. Sixteen had radiolucent gallstones and 9 had radiopaque gallstones. The radiolucent gallstones had a cholesterol content of 94.17 ± 3.76% and the radiopaque gallstones had a cholesterol content of 56.6 ± 4.46%. Half the maximal response (ED₅₀) to cholecystokinin octapeptide (CCK-OP) and to carbachol in strips from patients with radiolucent gallstones was 0.8 ± 0.15 and 27.01 ± 3.74 × 10^-7M, respectively. In strips from patients with radiopaque gallstones, the ED⁵⁰ was 0.4 ± 0.08 and 14.92 ± 3.07 × 10^-7M, respectively. The ED₅₀ values to CCK-OP and carbachol were greater in strips from specimens with radiolucent gallstones than in strips from specimens with radiopaque gallstones (p < 0.05). There was no significant difference in the maximal contractile response of the two groups. It can be concluded that gallbladder sensitivity to CCK-OP and carbachol can be modified in relation to differences in the cholesterol and calcium content of the stones.

“…Goldberg et al [10] reported an accuracy of 68% when evaluating the presence or absence of gallstones in their 38 patients whose gallbladders had not visualized by oral cholecystography. The overall accuracy of gallbladder ultrasonography was 84% in the series reported by Doust et al [5], 92.8% in the series of Lutz et al (18), and 90% in the series of Arnon and Rosenquist [19].…”

Abstract. Grey-scale ultrason.ography is a relatively new diagnostic modality which can be employed to evaluate the cholecystographically nonvisualized gallbladder and the jaundiced patient. The procedure is simple to perform and causes no discomfort to the patient. Ultrasonography can detect gallstones and differentiate obstructive (surgical) from hepatocellular (medical) jaundice. Frequently, it is also instrumental in diagnosing the cause o f biliary obstruction in the patient with obstructive jaundice. Eleven illustrative cases are presented in which ultrasonography played a key role in establishing the correct diagnosis.Key words: Biliary tract, obstruction -Gallbladder, calculi -Gallbladder, ultrasound. AnatomyThe normal gallbladder is usually closely applied to the inferior surface of the right lobe o f the liver.Ultrasound is a useful diagnostic tool in evaluating the gallbladder which is inadequately visualized by oral cholecystography [1 5]. This noninvasive procedure is simple to perform and causes no discomfort to the p~/tient. Ultrasonography of the cholecystographically not visualized gallbladder is possible, because this diagnostic modality depends only on the morphology and acoustic characteristics of the gallbladder and is independent of hepatic and biliary functions. The bile-filled gallbladder can readily be demonstrated by ultrasound in most patients. A 92-98% visualization rate has been reported in normal fasting individuals [2,[5][6][7][8]. We would like to demonstrate the efficacy of this technique by presenting a number of illustrative cases in which gallbladder ultrasonography played a key role in establishing the correct diagnosis.
