Study on the effect of the growth regulator CGA 163935 on winter cereal crops

Au cours de la saison culturale 1990-1991, le régulateur de croissance CGA 163935 (MODDUS) a été appliqué selon différentes modalités sur froment d'hiver et escourgeon. Dans ces essais réalisés en région limoneuse belge sur des cultures conduites de manière intensive, l'influence de ce nouveau régulateur de croissance à action antiverse a été mesurée sur la longueur de la paille, sur la résistance à la verse, sur le rendement en grains et la qualité de la récolte et comparée à celles résultant de l'application de régulateurs agréés en Belgique sur ces cultures

Diagnostic précoce des récidives anastomotiques après chirurgie pour cancer rectal: utilité de l'échoendoscopie

Preoperative staging of rectal carcinoma by endoscopy, conventional radiology or CT scan is usually very disappointing for both depth of the infiltration into the rectal wall or perirectal tissues and in detection of parietal lymph nodes. In the same way, local recurrences are diagnosed too late by the same methods and chances for curative reintervention are very low. The aim of this study is to evaluate the clinical value of EUS in early diagnosis of local recurrence. For 40 months, 136 EUS were performed [with the Olympus GF-UM2, GF-UM3 or CF-UM3 echoendoscope (7.5 MHz or 12 MHz)] in 81 patients as follow-up after surgical resection of a previous rectal carcinoma. We performed EUS examination of the rectal suture and 10 cm above and below, every 6 months. In the post-operative follow-up group of 81 patients 23 cases of recurrence were suspected by EUS,- 14 underwent second look surgery, with confirmation of the diagnosis in all of them (only 5 of 14 were positive at endoscopic biopsy), - 7 patients did not undergo for second look surgery - 1 had no evidence of recurrence 20 months after EUS. - 1 patient had 2 positive EUS but negative biopsies, the patient wanted like to have a third EUS before surgery. 58 patients demonstrated no recurrence at EUS (no false negative). Various abnormalities can be observed in the suture area but only hypoechoic nodule -usually in the submucosa or muscularis propria - is of diagnostic value. Our results show that EUS is one of the best procedures currently available for assessing parietal involvement and staging of rectal carcinoma. EUS might be able to guide therapeutical options. EUS is a sensitive method to early diagnose local recurrence and lets the surgeon the opportunity for a second surgical - maybe curative - resection. © 1994 Springer-Verlag.SCOPUS: ar.jinfo:eu-repo/semantics/publishe

DONNEES CLINIQUES, ENDOSCOPIQUES ET HISTOLOGIQUES CHEZ 1100 PATIENTS DONT 574 COLONISES PAR CAMPYLOBACTER PYLORI

Of 1,100 patients checked by at least two diagnosis tests (urease, histology, culture) 574 (52.1 p. 100) were found to have Campylobacter pylori (C. pylori) in their antral mucosa. Significantly frequencies of C. pylori (p 60 g/day) and non steroid antiinflammatory drugs (NSAID) intake were not predictive for the presence of C. pylori but smokers were significantly at risk when the total (n = 1,100) population was taken into consideration. C. pylori was found in 29 p. 100 of asymptomatic controls (n = 31). There was no significant difference in the frequency and intensity of symptoms when comparing C. pylori+ and C. pylori- patients. The macroscopic aspect of the antral mucosa was not predictive since 51 p. 100 patients with normal endoscopy were C. pylori+. A strong correlation was observed between the incidence of C. pylori and the severity of gastritis at histology (p < 0.001) and C. pylori was found in 7 p. 100 of patients with normal histology. A sympatomatic index was prospectively established for 200 out-patients with NUD: in 70 C. pylori+ patients, improvement of symptoms was observed whatever the treatment (bismuth salts, amoxicillin, anti-H2, placebo) but significant rates of C. pylori clearance and improvement of gastritis were observed only in patients treated with bismuth salts or amoxicillin.SCOPUS: NotDefined.jinfo:eu-repo/semantics/publishe

Hard or recurrent gastrointestinal bleeding: Etiology and diagnostic pitfalls

We retrospectively investigated digestive bleeding of obscure origin, selecting patients where at the first gastroscopy and sigmoidoscopy the definitive diagnosis was not made. We identified three clinical situations: [1] cataclysmatic upper digestive bleeding with major hemodynamic consequences; [2] upper digestive bleeding with presence of blood in the stomach without any identified focal lesion. Submucosal non erosive hemorrhagic gastritis, secondary to venous malformations or ischaemic lesions, is the most significant etiological finding; [3] recurrent digestive bleeding without blood in the stomach may be of gastric, intestinal, or colonic origin. The diagnosis of gastric lesions necessitates repeated emergency gastroscopy with stimulation of the gastric mucosa. Laparotomy identifies half of the small intestinal lesions. Pancolonoscopy identifies angiodysplastic colonic lesions.SCOPUS: NotDefined.jinfo:eu-repo/semantics/publishe

Multipolar (BICAP) endoscopic coagulation in hard bleeders from upper gastro intestinal tract ulceration: A prospective study

In order to assess the efficiency of endoscopic multipolar electrocoagulation (BICAP), a prospective study was undertaken in 1981 in a selected population of hard bleeders from various lesions of the upper gastro intestinal tract. Until May 1988, 137 patients (13.9% of 985 acute upper GI investigated by our group) have been included according strict condition(s): arterial spurting at emergency endoscopy, rebleeding during hospital stay, admission hematocrit below 25%, prothrombin time below 50 or grade 3-4 shock. The frequency of usual high risk factors was: renal failure and coagulation disorders in 15% of patients, onset of the haemorrhage in this hospital in 28% and respiratory distress in 24%. BICAP therapy alone allows permanent hemostasis in 94% of acute GD ulcers (n = 32) and in 77% of chronic GD ulcers (n = 82). Success rate was significantly lower in patients with severe lung disease or chronic duodenal ulcer (mainly lying on posterior wall) but did not depend on the hemodynamic status nor the presence of pumping artery or visible vessel. No complication was observed and since portability and low cost are additional advantages, BICAP coagulation must be recommended for an efficient and rapid management of hard bleeders from upper GI tract ulcer.SCOPUS: NotDefined.jinfo:eu-repo/semantics/publishe

Management of rectal foreign bodies

The presence of foreign bodies inserted into the rectum is not an uncommon situation. Precise guidelines for the management and extraction of these foreign bodies are not frequently described in the literature. Anal access, whether endoscopic or surgical, varies depending on the type of foreign bodies, their size and morphology, and their location in the lower digestive tract. In this report, we describe a case of three rectal foreign bodies that necessitated a mixed endoscopic and surgical approach, and provide a review of the literature.SCOPUS: ar.jinfo:eu-repo/semantics/publishe
