Factors determining the occurrence of serum agglutinins to eubacterium and peptostreptococcus species in patients with Crohn's disease and ulcerative colitis.

Recently, the demonstration of serum agglutinins to Eubacterium and Peptostreptococcus strains has been found to be useful as a diagnostic test for Crohn's disease. Therefore, conditions determining the occurrence of these antibodies were studied in patients with Crohn's disease and ulcerative colitis. Localization of Crohn's disease in the colon, the presence of fistulae and serum levels of immunoglobulins were found to be contributory determinants for the occurrence of the agglutinins.

Carcinoma of the esophagus: results of treatment.

The treatment results of the Rotterdam working group on esophageal cancer during the period January 1970-January 1978 were assessed. A total number of 328 patients were treated: 230 males and 98 females. Of the 133 patients eligible for a combined treatment modality i.e. preoperative radiotherapy and surgery, 52 showed irresectable or metastatic disease during operation. The five year actuarial survival rate of the 81 patients, in whom curative surgical resection of the tumor was performed, amounted to 21%. Females fared better than males, the five year survivals being 42% and 12% respectively. This female preponderance in survival is partly explained by the considerable postoperative mortality of the male patients: 28% vs 7.4% in females. Patients who received only radiation therapy, whether curative or palliative, had a very bad prognosis. It is concluded that preoperative irradiation followed by surgical removal of the tumor should be performed in all operable-curable patients.

Abnormal blood vessels of the prepyloric antrum in cirrhosis of the liver as a cause of chronic gastrointestinal bleeding.

Three elderly females presenting with iron deficiency anaemia and faecal loss of blood were found to have a macronodular cirrhosis of the liver and an unusual red spotty appearence of the prepyloric antral mucosa. One patient underwent antral resection and the surgical specimen revealed abnormalities of the (sub)mucosal blood vessels. Anaemia and occult faecal blood loss disappeared after operation. It is suggested that this type of antral vascular abnormality is aetiologically related to hepatic cirrhosis and may represent a gastric equivalent of cutaneous spider angiomata.

Therapy of esophageal carcinoma. Results from the Joint Group on Esophageal Carcinoma in Rotterdam.

During the period 1978-1981 172 patients were referred to the Rotterdam Joint Group on Esophageal Carcinoma. Ninety-one patients were considered for combined therapy, comprising radiation therapy and surgery, and 10 patients refused surgery. The figures given in this material are actuarial survival values corrected for intercurrent death (the actuarial overall survival in parentheses). The 4-year survival in 69 patients who completed this treatment was 39 per cent (26%) (significantly better for women compared with men; significantly better for tumors less than 2 vertebrae compared with tumors greater than or equal to 2 vertebrae). The resectability rate was 85 per cent and the operation mortality rate 20 per cent. Thirty-eight patients had curative radiation therapy with a 4-year corrected survival of 5 per cent (3%). For palliative treatment, radiation therapy and endoscopic introduction of a Celestin tube were mostly used. The results of curative as well as of palliative treatment of esophageal carcinoma have shown improvement during the past decade compared with an earlier period.
