[The development of malignous tumours is a prolonged, multistage process. The onset of clinical symptoms and subjective complaints is preceded by the preclinical detectable phase, during which the tumour does not cause any symptoms but it has some signs and can be detected by screening. Information on the tumour’s natural history is of practical importance for choosing the screening strategy. When evaluating screening results, the various biases related to biological reasons need to be taken into consideration.]

[Experiences about the breast diagnostic methods are accumulating year-to-year, rapidly. Therefore the current examination algorithm is changing continuously. New diagnostic and therapeutic modalities are entering into the daily practice. Some of them became obsolete, so far their application is becoming a faulty decision. Some other methods become obligatory steps in the diagnostics. These are the reasons why the up-to-date knowledge of the literature is mandatory. Systematic review of the most recent articles of the last two years (January 2005-December 2006) of breast radiological diagnostics and the actual place of the imaging and interventional methods are presented. The following topics are summarized: breast cancer screening with conventional and digital mammography, computer assisted diagnostics (CAD), high risk patients' screening, US, MRI, MSCT, PET/CT, diagnostic interventions, differential diagnostics, percutaneous tumour ablation, therapy-related questions in the diagnostic work up.]

[The importance of recognition and proper treatment of hypertension and the maintenance of adherence in hypertension care]

NEMCSIK János, PÁLL Dénes, JÁRAI Zoltán

[Hypertension is the leading cause of death and disability-adjusted life years. In the United States hypertension accounts for more cardiovascular (CV) deaths than any other modifiable CV disease risk factor and was second only to cigarette smoking as a preventable cause of death for any reason. In our country the situation is similar. In Hungary the number of subjects with hypertension is approximately 3.5 million and this high prevalence contributes markedly to the poor Hungarian CV morbidity and mortality figures. The recognition of hypertension, the initiation of drug therapy and the long-term follow- up of the patients is mainly the task of primary care. Besides that it inheres high responsibility, this is also a grateful commitment, as hypertension in most of the cases can be treated properly with lifestyle-changes and medications leading to a marked decrease of CV complications, especially stroke. In our review article we would like to focus on the high prevalence of hypertension worldwide as well as in our country, the exact implementation of screening, the risk reduction potential of the proper treatment and the importance of the long-term maintenance of treatment adherence.]

[POSSIBILITES AND DIFFICULTIES OF COLORECTAL CANCER SCREENING IN HUNGARY]

ÚJSZÁSZY László, SIMON László, HORVÁTH Gábor, TAM Beatrix

[The frequency of colorectal cancer is increasing all over the world. It is the second most frequent oncological disease leading to death in both sexes in Hungary. The main part of colorectal cancer develope after the age of 50. In case of patients having higher risk we have to calculate with the earlier appearance of the tumour and detectable molecular genetic disorders. The development of colorectal cancer needs a long time. Before the appearance of the cancer, precancerous processes (adenomas, polyps) can be detected in the large intestine. The development of colorectal cancer can be prevented by the removal of the adenomas (polypectomy). There are many different and efficient methods to detect the precancerous and early disorders. For increasing the compliance to screening programs the common efforts of the society, the National Health Care Services and medical doctors are necessary. The education of the population and the medical services would also be helpful. The colorectal cancer screening programs are costeffective and supported by the different health services independently from the type of the insurance. Screening the patients having higher risk is one of most important task. In these cases the use of colonoscopy is the most frequent method for the screening and follow up as well.]

[Health Protective Screening Program of Hungary 2010-2020. Metabolic syndrome - Results in 2010-2012]

KÉKES Ede, BARNA István, DAIKI Tenno, DANKOVICS Gergely, KISS István

[1 597 163 health assessments were performed on 65267 persons as a part of screening program. 132 964 participants were participated in our lifestyle advice program. The number of questionnaire responses for health statue were 3 717 480 during three years. This publication presents the results of metabolic disorders explored by screening. The metabolic syndrome was characterized by visceral obesity, abnormal glucose level and elevated blood pressure. Reasonable suspicion of metabolic syndrome was occured in 33-38% of subjects. Where the positive criteria was present, there were higher values of investigated parameters (waist, glucose, cholesterol, systolic blood pressure, uric acide level) compared with those of negative criteria.]

[The role and scope of screening and diagnosing obstructive sleep apnea syndrome by the family physician]

ANNUS János Kristóf, ÁDÁM Ágnes, BECZE Ádám, CSATLÓS Dalma, LÁSZLÓ Andrea, KALABAY László, SZAKÁCS ZOLTÁN

[Diagnosis and treatment of sleep disorders play an increasingly important role in everyday clinical practice of family physicians. Obstructive sleep apnea syndrome (OSAS) is a significant disorder of this disease group due to its relatively high incidence rate and increasing risk of adverse medical outcomes in the course of time. The prevalence of OSAS is 2-4% in the general population. It is characterized by obstructive apneas and hypopneas mostly with desaturations and/or arousals caused by the repetitive collapse of the upper airway during sleep. Besides impairing sleep efficacy and daytime neurocognitive functions, OSAS increases cardiovascular risk as well. The typical clinical presentation is an excessive daytime sleepiness and loud snoring interrupted by brief pauses of breathing. It can be a risk factor for treatment-resistant and/or non-dipper hypertension, nocturnal cardiac arrhythmias, stroke, cognitive decline and depression. The importance of OSAS is presented by the fact that - according to the latest related Hungarian law reforms - risk evaluation of the disorder is part of the medical assessment of suitability for a driving license. The family physician’s tasks are to recognize the clinical symptoms, identify high-risk patients with potential complications who need adequate treatment and eventually guide them to sleep-diagnostic centers. ]
