RESUMEN
Radiofrequency thermal ablation (RFA) is widely used and has been accepted for the treatment of unresectable tumors. The leading technique that is used is percutaneous RFA under CT or US guidance. Multicenter surveys report acceptable morbidity and mortality rates for RFA. The mortality rate ranges from 0.1% to 0.5%, the major complication rate ranges from 2% to 3%. Diaphragmatic injury is a rare complication and it is described after RFA of subdiaphragmatic tumors. Most of them are without clinical importance. There are some case reports about diaphragmatic herniation of the intestine into the pleural cavity. We present a case of diaphragmatic perforation resulting in the herniation of the liver into the pleural cavity. A thoracotomy was performed, the liver was lowered back into the peritoneal cavity and the perforation was closed with mesh.
RESUMEN
This article reports a case of a female patient who presented with epigastric pain. Further investigations confirmed CMV infection as a cause of stenosing gastric ulcer. In this case treatment with a proton pump inhibitor and antivirotic treatment led to a full recovery. Orgain manifestation of CMV infection if often in immunocompromitant hosts and it is, on the contratry, relatively rare in immunocompetent adults.

Pancreatic cancer still remains one of the tumors with the worst prognosis. The five-year survival rate ranges between 0.4 to 2 per cent. In most cases the tumor is diagnosed at an advanced stage, which does not allow a radical surgical treatment. Currently, the diagnosis of pancreatic cancer is based on dynamically developing imaging methods that allow detecting even small lesions. The basic testing method is the contrast computed tomography which is, in most cases, linked up to the endoscopic ultrasonography. In most patients results of the cytopathological and histological examinations are obtained before surgical or oncological therapy. The decisive factor for further therapeutic approach is the tumor staging. Despite the apparent progress in diagnostic techniques, the early diagnosis of pancreatic cancer remains unsatisfactory.

BACKGROUND: Despite the introduction of new imaging methods, the prognosis of pancreatic carcinoma (PC) remains hopeless. Therefore, there has been exerted much effort to elucidate the risk factor enabling the diagnosis of PC in the "preclinical state". At the time of PC diagnosis, more than 30% of patients suffer from diabetes mellitus, much more often than in the rest of the population. It is not clear whether DM is a risk factor for PC onset or DM appears secondary to the destruction of the gland by the tumor progression or by the effect of unknown factors produced by the cancer cells. METHODS AND RESULTS: We enrolled 204 individuals into the study, 69 of them were controls, 70 patients had type 2 diabetes mellitus and 65 cases had newly diagnosed PC. The patients with PC had in 68% of cases disturbed glucose homeostasis and significantly higher values of insulin resistance index (HOMA-IR) in comparison with the control group. The presence of glucose homeostasis disturbances does not influence tumor staging and localization. CONCLUSIONS: Results of our pilot study confirmed the so far unsatisfactory state of PC diagnostics (majority of cases fall to stages III and IV) and corroborated the close relation to DM. The early markers for the risk of pancreatic carcinoma development should be searched among the factors participating in the regulation of the glucose homeostasis and insulin sensitivity.
