[Sweet syndrome associated with Crohn disease].

The association of Sweet's syndrome and Crohn's disease is rare. We report a new case of such association. A 45 year-old woman developed a diarrhea, fever, and skin lesions consistent with a presumptive diagnosis of Sweet's syndrome. Crohn's disease was also diagnosed. Oral prednisone, associated with mesalazine, effected improvement of both cutaneous lesions and bowel disease. The ten cases of the literature and ours show that Sweet's syndrome may occur during an acute phase of Crohn's disease. Most of the time, Crohn's disease has already been diagnosed. However, this was not so with our patient, wherein lies the originality of our case. A general corticotherapy is the preferred course of treatment.

[Quality of psychomotor recovery after colonoscopy under general anesthesia using propofol. Value of tests of awakening].

Achieving colonoscopy under general anaesthesia entails the problem of ambulatory-care anaesthesia, in particular because perception of patient's recovery determines to some extent the length of monitoring following colonoscopy. The aims of the study was to assess the quality of patient's recovery after a colonoscopy under general anaesthesia while using propofol, by means of psychomotor-tests. METHODS--Colonoscopy was performed in 40 patients according to the following anaesthetic protocol: induction: propofol 2 mg/kg, continuous support: propofol 10 mg/kg/h i.v. with a 50 mg bolus in case of insufficient sedation; series of 3 psychomotor-tests were performed the day before and 1 hour, 3 hours and 6 hours after colonoscopy. The 3 psychomotor-tests studied: coordination (Newman test), time-space orientation and short-term memory. RESULTS--Forty patients, 25 females and 15 males, underwent colonoscopy with general anaesthesia for an average time-period of 22 +/- 11 min. The mean dose of propofol used was 286 +/- 102 mg. Awakening was complete in all patients, according to physical criteria such as consciousness and cardiovascular status, 20 min after receiving colonoscopy. The average psychomotor-tests results over time were (as percentages of original values) (*P < 10(-3); **P < 0.05): [table: see text] At 6 hours, 35 patients (87.5%) had recovered to their original performance and at 3 hours, 30 patients (75%) retained 90% their former state as measured with 3 psychomotor-tests. Neither by age or sex nor by propofol doses used or length or anaesthesia, the study population differed significantly. CONCLUSION--Three hours after colonoscopy under general anaesthesia using propofol, 30 patients (75%) had recovered at least 90% to their initial performances. Newman test was the most disturbed but there was no predictive factor for the quality of recovery. Psychomotor-tests may be useful before authorizing early discharge after colonoscopy under general anaesthesia but other recommendations about conditions of discharge after sedation must be also implemented.

[Necrotizing amebic colitis].

We report a case of necrotizing amebic colitis in a 43 year-old patient, 10 years after a stay in Senegal, successfully treated by right hemicolectomy. Entamoeba histolytica were found in colon necrosis and amoebiasis serology was positive, leading to the diagnosis. The epidemiologic, physiopathologic, clinical and therapeutic features of this exceptional affection are described. A few cases have been previously reported in non endemic areas where pre-operative diagnosis is rarely made. In endemic areas, a conservative treatment by ileostomy and colonic lavage seems to reduce the death rate.

[Quality assessment of colonscopies in current practice in the Aquitaine area].

UNLABELLED: Sensitivity of colonoscopy depends on the technical quality of the procedure. The aims of this study were to evaluate the usual of colonoscopy in the French area of Aquitaine and to determinate the factors associated with a procedure of good quality. Thirty four gastroenterologists prospectively recorded indications, conditions of practice and results of the colonoscopies that were performed during 4 consecutive weeks. Six hundred and eighty six colonoscopies were analysed, performed in 387 women and 299 men, mean age: 59.9 years. INDICATIONS: irritable bowel syndrome: 34%, patients belonging to high risk groups: 30%, recent transit disturbance: 27%, rectal bleeding: 23%, positive fecal occult blood test: 4.3%. Preparations: polyethylene glycol (PEG) 78%, in 2 doses: 20%; PEG alone: 43%, associated with enemas and laxatives: 19%, with enemas: 14%, with laxatives: 2%; minimum-residue diet before colonoscopy: 58%. The caecum was reached in 86% of colonoscopies. Ninety-nine colonoscopies were incomplete. Fifty one per cent of colonoscopies reached the caecum with visualization of total colic mucosa, 35% reached the caecum with one at least imperfectly seen colic area.(ABSTRACT TRUNCATED AT 250 WORDS)
