[Antiphospholipid syndrome is a recently recognized clinical entity characterized by the presence of deep vein and cerebral thrombosis, thrombocytopenia and recurrent fetal loss. The syndrome is caused by autoantibodies directed against phospholipid antigens. The clinical syndrome is most frequently associated with systemic lupus erythematosus.]

[Our preliminary experience with intraoperative ultrasonography during laparoscopic cholecystectomy is presented. The importance of intraoperative diagnostic procedures in biliary surgery such as cholangiography and operativ ultrasonography are discussed.]

[The two groups did not differ from each other in terms of improvement in clinical symptoms. Using a visual analogue scale and the Likart questionnaire, breathlessness appeared to be relieved with the active agent, but the duration of exertion or exercise capacity was found to be the same. Exercise-induced tachycardia and blood pressure elevation were attenuated with xamoterol (p < 0.01). The drug showed no arrhythmogenic effect. At 100 days after randomisation, 32 patients in the xamoterol group (9.1%) had died, compared with 6 (3.7%; p=0.02) of those treated with placebo.]

[The patho-histological characteristics of alcohol induced acute and chronic organ and tissue injuries were reviewed. Neuropathy and brain lesions, gastrointestinal tract in alcoholism, alcoholic liver disease, pancreatitis, cardiomyopathy, aseptic bone necrosis, rhabdomyolysis were discussed based on the literature. ]

[Each year tumours, including oral cancers, result in more and more deaths in Hungary. The oral cavity has a special position, because the precancerous lesions and conditions which occur in it can be detected by simple procedures. The authors use the latest definitions and disease classifications approved by WHO, to systematize the essential knowledge for the early diagnosis of the most frequent precance roses in Hungary, taking into consideration aspects of clinical morphology, epidemiology, localizational frequency, the risk/level of the tumour and the main principles of treatment. In addition to a detailed description of leukoplakia, erythroplakia, smoker's palate, actinic cheilitis, lichen and sideropenic anaemia, cheilitis glandularis, cornu cutaneum, naevus pigmentosus, discoid lupus erythematosus, submucosus fibrosis, xeroderma pigmentosum and tertiery syphilis are also mentioned. The purpose of the review is to call attention to the fact, that, due to the significant increase in mortality caused by oral tumours, the early diagnostic activity of dentists should be supported by the awareness of general practitioners and a national stomatooncological screening network should be established. ]
