[Crohn's disease: disease activity and recurrence following surgery].

The data from 238 patients (108 men, 130 women, mean age 29 [15-71] years), who had undergone operations for Crohn's disease between 1968 and 1988, were analysed retrospectively with the purpose of ascertaining the significance of an endoscopically demonstrated "early recurrence". In 170 patients postoperative colonoscopy had been performed at least once. In 130 patients the activity of the disease in the years before and after operation was compared in terms of such parameters as haemoglobin, erythrocyte sedimentation rate, serum albumin, body weight and the frequency of acute flare-ups of the disease and admissions to hospital. The probability of an endoscopically demonstrable recurrence was 90% after 5 years, while the corresponding figure for a symptomatic recurrence was 40%. This indicates that the routine performance of postoperative colonoscopies is of no value in assessing the prognosis. The probability of a reoperation was 21% after 5 years; in cases where both the ileum and colon were involved the probability was three times as high as in those with isolated involvement of either the small or the large intestine. Post-operatively, a substantial reduction in disease activity of several years' duration was achieved in the overall majority of cases.

[Meckel's diverticulum and lower gastrointestinal bleeding. Problems of preoperative diagnosis].

A hitherto perfectly healthy 28-year-old man suddenly passed stools containing bright red blood, and haemoglobin concentration fell at first to 10.1 g/dl. No bleeding source was found on gastroscopy and coloscopy. Nor was the source found by enteroclysis during a bleeding-free interval. Emergency laparotomy was performed after a recurrence of massive bleeding and revealed, 60 cm oral of the ileocaecal (Bauhin's) valve, a Meckel's diverticulum with ulcerated heterotopic gastric mucosa, 5 x 3 x 2 cm in size, and this was resected. 17 red blood cell concentrates had to be infused pre- and postoperatively, but there were no further complications.

[Rocky Mountain spotted fever].

After returning from a holiday in the USA a 24-year-old man fell ill with diarrhoea, high fever and marked rash including the palms of the hands and soles of the feet. When a history of a tick bite in the USA was elicited, a rickettsial infection was suspected. Treatment with doxycycline, 100 mg twice daily, was instituted finally and the fever slowly resolved. The patient became completely well again within four weeks. Serological tests confirmed the diagnosis of Rocky Mountain spotted fever.

[Cheilitis granulomatosa as the first manifestation of Crohn's disease].

A 39-year-old man developed a painless swelling of the lower lip, which histologically was a granulomatous inflammation of the corium as in granulomatous cheilitis. Four weeks after onset of the disease recurrent diarrhoea set in, the result of Crohn's disease of the jejunum, terminal ileum and caecum. Granulomatous cheilitis, occurring as sole sign of the Melkersson-Rosenthal syndrome, is a manifestation of Crohn's disease. Even if there are no intestinal symptoms. Crohn's disease must be excluded in the differential diagnosis.

Diagnosis of fistulae and sinus tracts in patients with Crohn disease: value of MR imaging.

To investigate the potential of MR imaging in the evaluation of sinus tracts or fistulae associated with Crohn disease, 17 patients with pelvic or abdominal fistulae or sinus tracts underwent MR imaging with multislice spin-echo techniques, 500/15 and 1600/22,80 (TR/TE). The presence of fistulae and/or sinus tracts was confirmed by contrast-enhanced CT (n = 17) and/or sonography (n = 8), sinography (n = 6), or barium studies (n = 4). In all but three cases the fistulae and extramucosal inflammatory abnormalities were shown by MR. T1-weighted images provided excellent delineation of the extension of the fistulae relative to sphincters and adjacent hollow viscera and showed inflammatory changes in fat planes. T2-weighted images showed fluid collections within the fistulae, localized fluid collections in extraintestinal tissues, and inflammatory changes within muscles. The supralevator and infralevator compartments were well defined on coronal images. Thus, the perirectal spread of fistulae and sinus tracts with respect to the levator ani could be demonstrated in all cases. Our results suggest that MR imaging is useful for the demonstration and evaluation of pelvic and abdominal sinus tracts or fistulae associated with Crohn disease.

[Pericardial effusion during the therapy of Crohn's disease with 5-aminosalicylic acid].

A 22-year-old woman with Crohn's disease was treated with 5-aminosalicylic acid (Claversal), four times 500 mg daily, because of increased inflammatory activity. Retrosternal pain set in after two weeks; in another two weeks a moderately enlarged heart was noted on the chest X-ray and pericardial effusion diagnosed echocardiographically. After stopping the medication the pericardial effusion resolved without further treatment. Immunoserology failed to demonstrate autoantibodies, but a repeat lymphocyte stimulation test was positive. There is a possible causal relationship between 5-aminosalicylic acid medication and the pericardial effusion, although the pathogenetic mechanisms is not known.

[Primary biliary liver cirrhosis and granulomatous pulmonary infiltrates].

Primary biliary cirrhosis was diagnosed in a 48-year-old woman in the light of clinical and laboratory data, antimitochondrial antibodies and histologic features in liver biopsy. Four years later the patient developed pulmonary infiltration of changing localization. Histologic investigation of transbronchial biopsy revealed granulomas in the bronchial mucosa and peribronchial tissue. There were no further signs of sarcoidosis. The question is discussed whether granulomatous pulmonary infiltrations are an extrahepatic manifestation of primary biliary cirrhosis.

[Eosinophilic gastroenteritis with ascites].

Eight years after the onset of bronchial asthma a 28-year-old woman fell ill with abdominal pain, diarrhoea and rapidly increasing ascites. Increased numbers of eosinophils in the protein-rich ascitic fluid and histologically demonstrated eosinophilic infiltration of the intestinal mucosa, together with the history and symptoms, established the diagnosis of eosinophilic gastroenteritis. The disease proved self-limiting without specific treatment. Within four years of first manifestations there were two short recurrences with rapid regression without specific treatment.

[Intravenous subtraction angiography as a control examination following blood vessel surgery].

21 patients were examined after different, mostly peripheral vessel operations by intravenous angiography in combination with photographic subtraction. In all cases there was a diagnostic reliability on the documented findings. Structure of vessel-side, morphology of stenoses, formation of a collateral circulation, functioning of bypasses and arteriovenous shunts could be judged sufficiently by the conventional intravenous subtraction angiography (ISA). As a convenient method for the control of the arterial vessel side after vessel operation and angioplasty, the ISA is a suitable method when the digital subtraction angiography is not available. The image quality of the ISA at present is at least equivalent to that of the DVSA .
