Carcino-embryonic antigen (CEA) has been tested in numerous clinical studies, from its discovery in 1965. In the context of treatment for colorectal carcinoma, its importance is primarily related to early detection of recurrences following potentially curative operations. However, its value was found to be limited in primary diagnosis. In certain cases,… (More)
The level of the tumor marker tissue polypeptide Antigen (TPA) rises distinctly after a surgical trauma. The rise begins between 3 and 6 days after operation; the elevation lasts for more than 6 weeks. Carcinoembryonic antigen (CEA) shows no comparable reaction.
The monitoring of CEA is valuable in the follow-up after curative resection of colorectal cancer and contributes to the early detection of local recurrence and distant metastases. The simultaneous detection of the CA 19-9 does not lead to a substantial advantage. The recurrences and especially the metastases detected by the monitoring of the tumour markers… (More)
In 103 patients with colorectal carcinoma carcinogenic antigen, 19-9 (CEA), tissue polypeptide (TPA) and carbohydrate antigen (CA 19-9) were measured in serum. The values determined in these patients and in a control group have been converted into specificity-sensitivity diagrams. Comparison of diagrams of the three markers showed that CEA has the greatest… (More)
A series of 23 patients is reviewed admitted to our hospital for non traumatic perforation of the small intestine, a condition found very rarely as a cause of acute abdominal disease. The causes were primary small bowel neoplasia (four patients), adhesions (five patients), intraluminal foreign bodies (two patients), small bowel metastases (two patients),… (More)
Three cases of ischemic necrosis of the right colon in chronic dialysis-dependent patients are reported. Low flow states, mucosal lesions, and changes in blood viscosity are discussed as etiologic factors.
The potential predatory ability of Chironomus riparius, well-known detritus-feeding chironomid larvae, on nematodes was investigated in a series of laboratory experiments. We analyzed the consumption rate (i) for different prey densities of adult and juvenile Caenorhabditis elegans (25–1200 and 25–2400 prey individuals, respectively), (ii) for different… (More)
The tumor markers carcinoembryonic antigen (CEA), tissue polypeptide antigen (TPA), and carbohydrate antigen 19/9 (CA19/9) have been compared with regard to their sensitivity to liver diseases. All three markers have been found to be sensitive to liver diseases, but to a different degree: TPA rises the most; CEA the least. The sensitivities of TPA and… (More)
Retinol-binding protein, haptoglobin and ceruloplasmin were determined in the plasma of patients with colorectal carcinoma. The comparison with a control group shows that retinol-binding is significantly decreased in colorectal carcinoma and that haptoglobin and ceruloplasmin are significantly elevated. The ROC-curves of the three parameters, however,… (More)
In a 28-year-old woman right-sided pneumothorax developed during a laparoscopic cholecystectomy. The authors believe that the pneumothorax was caused by in the inflow of carbon dioxide into the thoracic cavity without injury to the diaphragm. So far, only a few reports of this complication exist, but in the future it will probably occur more frequently,… (More)
