[Gut-liver axis in inflammatory bowel disease. A retrospective study].

Introduction: Examination of the gut-liver axis came into the spotlight worldwide. Liver enzyme elevations are commonly seen in patients with inflammatory bowel disease (IBD), which is a diagnostic challenge in everyday clinical practice. Liver and biliary diseases are common extra-intestinal manifestations in Crohn's disease and ulcerative colitis.

Changes of erythrocyte element status of colectomysed cancerous patients: Retrospective study.

Nowadays it has been established that metals and metal-induced oxidative stress act on signal transduction pathways, and are in association with cancer growth and spreading as well as in neurodegenerative disorders. In cases of several neurodegenerative diseases metals, especially Al, can be considered as a risk factor. Frequency of chemotherapy-related cognitive impairment or "chemobrain" is mentioned to be significant in literature, although very little is known about the chemotherapy-caused chemobrain and its connection with metal homeostasis alteration.

[Dysmotility-type dyspepsia and eructation. Introduction of a new gas-analytical method].

This paper describes a new gas-analytical method used in a 55-year-old female patient with dyspepsia. Symptoms included epigastric fullness and inflation. Evaluation indicated an increased gas production in the proximal end of the small intestine that entered into the stomach via duodenogastric reflux.

Important bioactive molecules of erythrocytes in colorectal cancer patients after colectomy.

Formaldehyde (HCHO) and protoporphyrin, are in connection with redox homeostasis. Data show the importance of HCHO in proliferative as well as in apoptotic processes. Free protoporphyrin can be detected near the Zn-protoporphyrin in cancer and it has pro- and antioxidant forms depending on concentrations.

The importance of follow-up examinations in patients with carcinoid tumor.

Carcinoid tumors are rare forms of gastrointestinal tumors, although lately they have been found with increasing frequency. We report here the combined diagnosis of an intestinal metastasized carcinoid tumor. A 67-year-old patient was followed up during a nine-year period.

Comparative study between the free radicals and tumor markers in patients with gastrointestinal tumors.

The tumorous processes, increased level of tumor markers and the change of free radical status are associated in patents with gastrointestinal tumors. The aim of this study was to examine free radical status and tumor markers in patients with gastrointestinal tumors. Two hundered and thirteen patients with gastrointestinal tumor were examined.

[Occurrence of Helicobacter pylori in patients with gastroesophageal tumors].

Authors examined the occurrence of H. p. retrospectively in bioptic material for three years.

[Three-dimensional rectal ultrasonography in inflammatory bowel diseases].

Authors used three-dimensional ultrasound technique in diagnosing chronic inflammatory bowel diseases to demonstrate its activity and complications. For their examinations they adopted high-(7.5 MHz) frequency rectal transducers which made it possible to depict the layers and environment of the intestinal wall.

[Metastasized carcinoid tumor treated with interferon and octreotide].

The carcinoid tumours are rare forms of the gastrointestinal tumours (they make up 2%), though lately they have shown an upward tendency. Among different types of treatments of the carcinoid tumours in non metastatised cases, the surgical intervention stands first on the list. But when symptoms emerge, most of the tumours have metastases, for which there are various types of treatments.

[Serum acid alpha-1-glycoprotein (APG) levels in gastrointestinal tumors].

Using a new microanalytical method authors investigated the AGP level in the sera of 41 healthy individuals and 87 patients with and without malignant diseases of gastrointestinal tract verified clinically by other diagnostic (image forming) techniques. It could be stated that serum AGP levels measured in healthy persons were in good agreement with the data of others, and selecting 80 mg/dl concentration as upper limit of normal values (cut-off level, mean + 2SD) the specificity of the test for a healthy population was 95 per cent. AGP content in the sera of patients with various malignancies of the gastrointestinal tract, mainly of colon and stomach was significantly higher in comparison to the healthy controls.

[Gluing of sterile abdominal benign cyst walls with tissue adhesives (Tissucol) (preliminary report)].

The authors, endeavouring to stick the walls of percutaneously emptied cysts together had applied the two-component Tissucol fibrin glue in the treatment of abdominal and thoracic cysts. Their ten cases, however, may be considered only as preliminary experiences. It seems that the method can be recommended for an attempt to cease these formations in a fast and simple way.

[Ultrasound-guided percutaneous external catheterization-drainage of pancreas-related fluid collections].

The authors have extended the diagnostics indispensable in drainage of pancreatic fluid collections by intracavitary invasive methods. In five patients exfoliative cytology, in to patients target biopsy and in other two septotomy were performed. Intracavitary invasive diagnostic and therapeutic methods may be useful complementary tools with the traditional technique.
