OBJECTIVE To correlate disease course and complications in children with juvenile dermatomyositis (JDM) and polymyositis (JPM) with specific features of muscle pathology on biopsy. METHODS This is a retrospective cohort analysis of 59 children diagnosed with JDM or JPM between 1965 and 1998 and followed at the Cincinnati Children's Hospital Medical Center (CCHMC) for a mean duration of 7.3 ye...

BACKGROUND The aetiology and pathophysiology of ulcerative colitis remains unclear; however, there is increasing recognition of the critical role of inflammatory cytokines in the pathogenesis of this disease. Among these, tumour necrosis factor alpha (TNF alpha) seems to play an important role. AIM To study the effects of an engineered human monoclonal antibody to TNF alpha (CDP571) in the tr...

While it has long been established that the chemokine receptor CCR9 and its ligand CCL25 are essential for the movement of leukocytes into the small intestine and the development of small-intestinal inflammation, the role of this chemokine-receptor pair in colonic inflammation is not clear. Toward this end, we compared colonic CCL25 protein levels in healthy individuals to those in patients wit...

Because the normal faecal flora includes bacteria which can produce mucus-digesting glycosidases, it follows that increased digestion of colonic mucus by these bacterial enzymes could be important in the pathogenesis of ulcerative colitis. Faecal activities of potential mucus-degrading glycosidases have therefore been assayed in samples from patients with inflammatory bowel disease and normal c...

Ulcerative colitis is not commonly associated with recognizable pulmonary disease and only four sporadic cases of sarcoidosis in association with ulcerative colitis have been previously reported. However, in a series of 680 patients with ulcerative colitis, pulmonary or extra-pulmonary sarcoidosis has at some stage been present in eight. These cases are reported in detail. The onset of either c...

Epidemiological evidence suggests that ulcerative colitis is a disease of nonsmokers, while Crohn's disease is a disease of smokers. The relative risk of developing ulcerative colitis is not only greater in nonsmokers, in addition there appears to be a rebound effect in smokers who quit, with the heaviest (ex-)smokers increasing their relative risk of the disease the most. This factor poses an ...

We herein describe a rare case of ulcerative colitis associated with unilateral hypoglossal nerve palsy. A 64-year-old woman developed severe active ulcerative colitis and was treated with prednisolone. The dose of oral prednisolone was reduced to 7.5 mg/day, following which the patient noticed slight dysphagia and a speech disturbance. She was diagnosed with unilateral hypoglossal nerve palsy,...

Sarcoidosis--a chronic, multisystem disease of unknown etiology characterized by noncaseating granulomas--may cause ulcerative lesions, particularly in African American women. A case of ulcerative sarcoidosis mimicking a venous ulcer is presented. The patient is a 44-year-old African American hypertensive, obese woman with a nonhealing medially based lower leg ulcer of 3 years' duration clinica...

BACKGROUND Takayasu arteritis and ulcerative colitis are immune-mediated inflammatory diseases; genetic factors are assumed to play an important role in the pathogenesis of these 2 diseases. However, the coexistence of these 2 diseases has rarely been reported. CASE REPORT In this report, we present a rare case of a 29-year-old man with a 4 years history of ulcerative colitis who developed Ta...

Clostridium difficile has been implicated in the relapse of ulcerative colitis. Controversy exists over this role and its relationship to sulphasalazine exposure. Sixty two of 77 patients with a documented relapse of ulcerative colitis were investigated for the presence of Clostridium difficile, or its toxin, prior to hospitalization. There was a low incidence of detection which was related to ...
