The sonographic features of intra-abdominal pregnancy.

The sonographic features of three cases of extrauterine, intra-abdominal pregnancy are presented in conjunction with a brief review of the clinical and radiographic features of the condition. Based on our experience and a review of the literature, we found that the major criteria for the sonographic diagnosis of extrauterine, intra-abdominal pregnancy include: 1) demonstration of a fetus in a gestational sac outside the uterus, or the depiction of an abdominal or pelvic mass identifiable as the uterus separate from the fetus; 2) failure to see a uterine wall between the fetus and urinary bladder; 3) recognition of a close approximation of the fetus to the material abdominal wall; and 4) localization of the placenta outside the confines of the uterine cavity.

Sonographic features of carcinoma of the gallbladder.

The sonographic features of carcinoma of the gallbladder are reviewed. Four cases of carcinoma of the gallbladder are presented which illustrate some, but not all, of the sonographic findings resulting from this abnormality. The findings illustrated are (a) a small gallbladder containing stones associated with a mass in the porta hepatis, (b) diffuse gallbladder thickening, fixation, and irregularity, (c) a papillary mass with an irregular border projecting from the gallbladder wall, and (d) a small, localized area of gallbladder wall thickening associated with cholelithiasis. Although inflammatory disease of the gallbladder can present similar sonographic findings, the correlation of the clinical findings and close inspection of the sonographic changes illustrated and described in this publication may allow the only means of a preoperative diagnosis of carcinoma of the gallbladder.

Accelerated Fermentation of Brewer's Wort by Saccharomyces carlsbergensis.

A rapid procedure for wort fermentation with Saccharomyces carlsbergensis at 12 C is described. Fermentation time was reduced from 7 to 4 days with normal inoculum by shaking. Increasing the inoculation to 5 to 10 times normal and shaking resulted in complete fermentation in 3 days. Maximum yeast population was reached rapidly with the large inocula, but fermentation proceeded at approximately the same rate when inoculations in excess of four times the normal were used. Similar results were obtained with both small-scale (100 ml) and microbrew (2.4 liters) fermentations.
