ABSTRACT
A tap water enema combined with intravenous iodine contrast medium was used for computed tomographic (CT) study of the entire clean colon in 35 patients. Thirty of them showed a high suspicion of rectal, colon, or cecal pathology at either clinical examination, barium enema study, or endoscopy. The remaining five patients were examined for suspected local recurrence of carcinoma. This CT technique detected the wall abnormality in all but one case with two small adenomatous polyps. This procedure, which is simple, inexpensive, and has a good acceptance and tolerance, can accurately detect mural wall abnormalities.

Thirty-four patients with a high suspicion of gastric lesion at endoscopy were studied by two computed tomographic (CT) techniques: one using a gas-producing agent and the other using water as an oral contrast media. Intravenous contrast medium was also given in all patients who underwent the water technique. Final histologic proof was obtained either by endoscopy or at surgery. Both CT techniques detected the wall abnormality in 32 of the 34 patients, and both techniques missed the same lesion in two patients. The water technique showed more gastric wall details and the lesion's limits could be defined more accurately. The acceptance and tolerance of the gas-producing agent was better in severely ill patients than tap water.

The subject of this work is to describe one of the possible applications of the informatics system in medical bacteriology, its exploitation in edition of the analysis results and in the management of produced stocks. The informatics is presently a very productive tool giving a precise information, a very important time gain and a better control of the costs. This work admit two chapters. In the first one, we give general notions of informatics and in the second one we describe the applications.

Forty-five patients having previously undergone surgical removal of hydatid cysts were examined for recurrence using CT. Recurrence of hydatid disease was demonstrated in 11 patients. At the site of surgical cyst evacuation, cyst-like structures (pseudocysts) were demonstrated in 15 patients. Although pseudocysts were smaller than the original cysts and demonstrated a flattened appearance and a thicker wall, differentiation from recurrent viable hydatid cysts was difficult. Five of the pseudocysts had attenuation values between 10 and 35 HU, and eight had attenuation values close to that of fat (- 20 to - 100 HU). The findings of this study may be important in the follow-up of patients with hydatid disease.
