Pyoderma gangrenosum is a cutaneous disorder associated with systemic diseases such as ulcerative colitis, Crohn's disease, rheumatoid arthritis, and blood dyscrasias. We are reporting two cases of pustular pyoderma gangrenosum associated with ulcerative colitis. One patient had inactive bowel disease when she developed her third episode of pustules, erosions, and nodules on the left leg. The other patient exhibited a widespread painful vesiculopustular eruption that coincided with the onset of her colitis. Both patients presented with pustules as the primary manifestation of their pyoderma gangrenosum. Histologic examination of skin from both patients revealed an acute perifollicular inflammation. Pyoderma gangrenosum should be considered in the differential diagnosis of pustular disorders in children with underlying conditions such as ulcerative colitis.

Parameters in the differential diagnosis of enterocolitis have been poorly evident for many years. Development and profitable employment of endoscopic instruments were the first step towards advancing the diagnostic facilities in inflammatory bowel disease. The microbiologic examination of mucosal biopsies creates a new diagnostic dimension, and it distinctly seems to increase the diagnostic sensitivity for pathogens. Within fifteen months 152 patients admitted to the gastroenterologic unit with acute, or symptoms of exacerbated, bowel disease were examined for the aetiologic agents. Compared with former reports, idiopathic inflammatory bowel disease (IIBD) such as Crohn's disease (32.2%) and ulcerative colitis (18.4%) were decreased. Infectious colitis (22.3%), mostly Campylobacter or Yersinia infections, was, sometimes exclusively, diagnosed by bioptic microbiology, non-classifiable forms of colitis (21.7%), and rare forms (5.4%) were diagnosed more often. It proved to be important that IIBD was frequently superinfected by Campylobacter, Yersinia and Chlamydia, and the differential diagnosis was complicated, since these microorganisms can mimic IIBD. The results suggest that coloileoscopy combined with bioptic microbiologic investigation additional to faecal samples should include a search for Campylobacter and Yersinia. It appears indispensable that the final diagnosis "Crohn's disease" or "ulcerative colitis" should be confirmed by sequential coloileoscopy and microbiologic examination.

We have been able to isolate mycobacteria from intestinal specimens obtained by surgical resection or endoscopic biopsy from patients with Crohn's disease, ulcerative colitis, and noninflammatory bowel diseases. Nineteen slow-growing (Runyon groups I and III) and 17 rapid-growing (Runyon group IV) mycobacterial isolates were obtained. Slow-growing mycobacteria were recovered from approximately one-third of intestinal biopsy specimens from Crohn's disease, one-quarter of ulcerative colitis biopsies, and 40% of biopsies from noninflammatory bowel disease patients. Isolates were most commonly members of the Mycobacterium avium-complex. One isolate (from an ulcerative colitis patient) was biochemically similar to the Mycobacterium strain previously associated with Crohn's disease, and one from a Crohn's disease patient was Mycobacterium kansasii. The rapid-growing organisms were members of the Mycobacterium fortuitum-complex. In addition to conventional mycobacteria, spheroplasts (cell wall-defective forms) were isolated from 12 patients with Crohn's disease (most often from surgically resected colon) and 3 patients with ulcerative colitis; none were isolated from non-inflammatory bowel disease patients. We have been unable to identify a consistent relationship between the presence, or the species, of Mycobacterium and Crohn's disease. Our results do not support the proposed role of a specific mycobacterium in the pathogenesis of Crohn's disease. The cause of Crohn's disease remains unclear.

We used DNA-DNA hybridization to characterize a mycobacterial isolate, strain Linda, that was obtained from a patient with Crohn's disease and that has been reported to cause ileitis in experimental animals. We also investigated the association of this mycobacterium with Crohn's disease. Our results identified Mycobacterium strain Linda as a strain of Mycobacterium paratuberculosis, the etiologic agent of Johne's disease, a disease of ruminants that has some superficial resemblance to Crohn's disease. Sequences that hybridized with strain Linda DNA probes were detected in DNA extracted from human intestinal tissues from patients with Crohn's disease, ulcerative colitis, and noninflammatory bowel disease. These hybridizing DNA sequences were more prevalent in the muscle layers than in the intestinal mucosa, making it unlikely that they represented DNA from bacterial contaminants in the intestinal lumen. Measurement of the melting temperatures of the DNA-DNA hybrids formed between strain Linda probes and tissue DNAs indicated that the related sequences detected were of mycobacterial origin but were not identical to each other or to strain Linda DNA. These results do not support the proposed specific relationship between Mycobacterium strain Linda and Crohn's disease. The possible etiologic role of mycobacteria in Crohn's disease is discussed.

The pathology of the alimentary tracts of nine patients dying of Salmonella typhimurium infection is reviewed. Two patients had previous gastric operations, supporting previous reports that such patients are more susceptible to food poisoning. Four had no parietal (oxyntic) cells in the gastric mucosa, suggesting hypo- or anacidity. Only one had acute gastritis. None had acute enteritis, but in half of the patients, subtle histological changes suggested an 'enteropathy'. Acute diffuse colitis with abundant crypt abscesses, without stromal abscesses in the lamina propria, was the most constant finding and reparative features started very early, and occurred in later deaths. Under ideal circumstances this crypt abscess is readily distinguished from that of idiopathic ulcerative colitis, but can be confused with the crypt abscess of acute bacillary (sonne) dysentery. While the florid colonic changes may have settled in the late deaths, active inflammation is commonly present in the appendix mucosa on histology. The pathology of the alimentary tract in S typhimurium infection differs from that of S typhi and S paratyphi infections. There is little evidence of gastroenteritis, although subtle changes occur in the stomach and small intestine. The features are those of acute diffuse colitis with histological appendicitis, distinguishable from idiopathic ulcerative colitis.

Patients with Crohn's disease (n = 22), ulcerative colitis (n = 5), inactive Whipple's disease (n = 1), irritable bowel syndrome (n = 2), arthritis (n = 1) and Yersinia infections (n = 2) were examined with 111In-oxine labelled "mixed" leukocyte preparations (n = 12) or with 111In-oxine labelled "pure" granulocyte preparations (n = 21). Compared with barium enemas of the gut and colonoscopy, performed within of one week in 31 patients there was a correct location of infiltrated bowel segments in 24 patients (78%). The scan diagnosed more infiltrated segments in 4 patients (13%). In 3 patients it failed to diagnose one inflamed segment. In 24 patients the faecal 111In-excretion was expressed as percentage of the reinjected 111In-activity. All patients with non inflammatory bowel diseases and patients with inactive inflammatory bowel diseases excreted less than 2% of the reinjected 111In-activity. All but one female patient with active bowel disease excreted more than 2%. In 24 patients the correlation of ESR, CDAI and A.I. was available. There was a good correlation between ESR (r = 0.77, P less than 0.001), A.I. (r = 0.61, p less than 0.001) and the %-faecal faecal excretion. The 111In-labelling of white blood cells, especially of granulocytes, seems to be a reliable alternative method to localize infiltrated bowel segments and to assess disease activity in patients with inflammatory bowel diseases, compared to usually performed radiological, endoscopical and clinical methods.

Hypertrophic osteoarthropathy (HOA) in association with primary bowel disease is rare, but is usually seen in patients with chronic diarrheal states, such as Crohn's disease and ulcerative colitis. We record the first case of HOA associated with primary intestinal lymphoma in a patient who presented with chronic diarrhea.

Persistent diarrhoea with mucus-production developed in a 37 year homosexual man, and an initial diagnosis of ulcerative colitis was made after barium enema examination and rectal biopsy. The patient later developed cutaneous lesions which proved to be Kaposi's sarcoma, and the bowel lesion was also subsequently shown to be Kaposi's sarcoma. This tumour occurred as a manifestation of the acquired immune deficiency syndrome (AIDS). The patient was treated with alpha interferon, with partial regression of the skin lesions, but progression of the bowel tumour. Because of severe bowel symptoms, including episodes of subacute intestinal obstruction, the localised bowel disease was treated with radiotherapy. In view of the increasing incidence of AIDS, a diagnosis of Kaposi's sarcoma must be considered in homosexual men presenting with persistent diarrhoea, for which no infectious cause can be demonstrated.

The authors examined 1132 patients with chronic ulcerative colitis (CUC) seen at the Cleveland Clinic to clarify the relationship between the clinical features of colitis and the incidence and severity of erythema nodosum (EN) and pyoderma gangrenosum (PG). There were 21 patients (2%) with EN and 21 (2%) with PG, both of which affected those with active and extensive colitis. CUC was inactive in only 10% of the EN group and 20% of the PG group; it was left-sided in 20% of the EN group and 15% of the PG group. The mean duration of CUC before the appearance of EN and PG was 5 and 10 years, respectively. Three patients had consulted a dermatologist for PG before a clinical diagnosis of CUC was made. EN and PG recurred in 20 and 33% of cases, respectively. EN appeared almost exclusively on the legs, while PG appeared on various areas of the skin, including the site of ileostomy in one patient. EN was controlled with adequate medical or surgical treatment of CUC, but PG was relatively refractory, requiring specific treatment of its own in 30% of patients. In one case each, EN and PG recurred after subtotal colectomy but had resolved completely after proctectomy. In one patient, PG developed for the first time 1 year after total colectomy. Less than half of EN patients and two-thirds of PG patients ultimately had to undergo colectomy because of bowel disease. No patient required colectomy because of skin lesions.

The absorption of 75Se-23-selena-25-homotaurocholate (SeHCAT) was compared with vitamin-B12 absorption and conventional radiography in 44 patients with inflammatory bowel disease. The retention of SeHCAT was normal in 11 patients with ulcerative colitis but was abnormally low in 9 patients with terminal-ileal resection, 9 out of 14 patients with small-bowel Crohn's disease and in 2 out of 10 patients with Crohn's colitis. The 5 patients with small-bowel Crohn's disease and normal retention had either inactive disease or no radiological evidence of terminal ileal involvement. Measurements of the absorption of vitamin B12 did not discriminate between these groups, and there was very poor correlation between B12 and SeHCAT absorption (r = 0.506, P less than 0.05). There was extremely good correlation of SeHCAT retention measured using a wholebody counter with that measured using an uncollimated gamma camera (r = 0.96, P less than 0.001). The results suggest that SeHCAT retention may prove complementary to conventional methods of assessing small-bowel disease in patients with inflammatory bowel disease. As measurement by gamma camera is feasible, this test can be used in most departments of nuclear medicine.
