Conservative management of small adenomata in ulcerative colitis

OBJECTIVE AND METHODS: Patients with chronic ulcerative colitis may develop colitis-related dysplasia and/or sporadic adenomata. Differentiating between these two processes is important because they may dictate different therapeutic approaches. Although distinguishing features of sporadic adenomata versus colitis-related dysplasia have been suggested previously on an a priori basis, they have never been verified by follow-up analysis. We have identified six chronic ulcerative colitis patients whose discrete adenomata were managed conservatively, with subsequent continuation in their surveillance programs. RESULTS: Mean patient age was 69 yr with a mean 21.3 yr of ulcerative colitis. Surveillance endoscopy of 63 patient-yr duration yielded 24 adenomata. A mean follow-up after the initial adenoma diagnosis was 7.2 yr with no carcinoma identified (including the examination of one prophylactic colectomy specimen). One patient, with a 34-yr history of ulcerative colitis and a single sporadic adenoma subsequently developed dysplasia of flat mucosa 14 months later. CONCLUSIONS: Our findings concur with previous reports and indicate that small, discrete adenomata with morphology identical to those seen in the general population occur in patients with ulcerative colitis. Such lesions in patients older than 45 yr, with tubular or tubulovillous architecture and low-grade dysplasia, are effectively treated by polypectomy only and are not necessarily an indication for colectomy. However, sporadic adenomata and colitis-related dysplasia can develop metachronously. It is suggested that subsequent to a diagnosis of sporadic adenoma in a patient with chronic ulcerative colitis, surveillance should increase to colonoscopic examination every 6 to 12 months.     

Evaluation and management of the patient with ulcerative colitis

Subtalar joint dislocation is a rare entity, accounting for only 1% of all traumatic dislocations. The authors report a case of an adolescent with gradual lateral subluxation of an anatomically abnormal subtalar joint with no history of trauma, an extremely rare presentation. The patient also had a congenitally short limb. The patient underwent llizarov leg lengthening along with multiple surgeries of the subtalar joint. The choice of the Ilizarov technique to lengthen the leg and realign the subtalar joint in this case is discussed.     

X-ray symptoms in ulcerative colitis

Barium enema studies in 200 patients with ulcerative colitis were analyzed according to radiological symptoms. The results of the radiological examination were compared with those of rectoscopy and biopsy. In about 75 per cent of patients good agreement was achieved.     

Nephrotic syndrome in ulcerative colitis

Complicating disorders in various organs outside the intestinal tract are common in ulcerative colitis. This report deals with the occurrence of nephrotic syndrome in two patients with long-standing ulcerative colitis. In the patient studied in most detail, 2 episodes have taken place, the first developing into uremia. After colectomy had been performed, rapid improvement of renal function took place. The morphological changes in kidney biopsies were compatible with the presence of focal glomerular sclerosis. Activity in the complement system and a favorable response to steroid treatment indicate that humoral immune mechanisms are of pathogenetic importance with regard to the renal disease in these two patients. To our knowledge nephrotic syndrome has not previously been described as a complication to ulcerative colitis.     

Risk factors in ulcerative colitis

In 504 Jewish patients with ulcerative colitis the following risk factors were evaluated: sex, age at onset of disease, community group, extent of disease, and duration of disease. The disease was more severe in females. Severe attacks, weight loss, iron deficiency, liver disease and arthritis were significantly more frequent in females than in mles. Mortality was higher in patients who contracted the disease above age 50. The disease appeared to be more severe in patiets of Ashkenazi origin as compared to Orientals. The difference failed to reach statistical signifcance except for mortality. We confirmed the well-known adverse effect of extensive colonic involvement. Severe attacks, a severe course of the disease and extensive colonic involvement are more frequent with increasing duration of the disease.     

Appendiceal inflammation in ulcerative colitis

The epoxyalkanoyl derivatives were designed and synthesized as ACE inhibitors. Coupling of unsaturated carboxylic acids with amino acids and following epoxidation with dimethyldioxirane gave the epoxyalkanoyls with high yield. The inhibitory activity of synthesized compounds on angiotensin converting enzyme was IC50 values of 0.06-5.5 microM.     

Rifampicin for ulcerative colitis

The public health approach to injury control is now widely accepted. Since the development of this approach, there has been a shift in the perspective of public health programs to include broader definitions of health. There have also been increasing efforts to evaluate public health interventions in terms of health outcomes at the population level. In this context, it might be appropriate to broaden the focus of injury prevention to target more specifically injuries that are not life-threatening. Although they are not responsible for major morbidity at an individual level, they probably account for the greatest decrement in the health of the population as a whole.
