[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.]

[Prenatal detection of campomelic dysplasia by sonography]

NAGY Gábor, VRECZENÁR László

[INTRODUCTION - The campomelic dysplasia is a disorder characterized by short and bowed lower limbs resulting in dwarfism. CASE REPORT - In the case of a 21-year-old primipara woman the second screening ultrasonography raised the suspicion of short and bowed lower limbs of the fetus, at the 19th week of the pregnancy. Repeated examinations proved the presence of short and bowed femurs and tibias and abnormal echogenecity of the bones. The upper limbs were almost normal in length. During the 19th week of pregnancy, after a genetic analysis in agreement of the parents the pregnancy was interrupted without any complication. Photography and Xray of the fetus confirmed the diagnosis. CONCLUSION - Fetal ultrasonography should include exact size measurement and observation of the shape of the long bones, making possible the early detection of limb anomalies. The anomaly being proven by positive genetic analysis the pregnancy can be interrupted at the parents' request.]

[Fatigue - symptom or side effect]

TOKODI Zsófia

[Cancer-related fatigue (CRF) is common in most cancer patient, which has a high impact on the quality of their life. It affects not only the patient itself, but also their families and relationships. It is the most underreported, overlooked and undertreated symptom. The screening and adequate treatment of CFR is getting more attention nowadays and it became the subject of guidelines of several international expert groups like the ASCO) and the NCCN. In this review we would like to summarize the contributory factors of CRF, the screening methods, the clinical assessment and the interventions of patients with cancer related fatigue. We try to give guidance to distinguish fatigue as a symptom of disease progression or as a side effect that we can treat. But lastly the most important question becomes that why CRF is so underreported.]

[How to detect it? Dementia screening in primary care]

KÁLMÁN János, PAPP Edina, PÁKÁSKI Magdolna

[The early stage of dementia, the diagnostic and clinical importance of prodromal stages of dementia have been increasingly recognised in the past few years. Nowa - days, simple, rapid, easy to use cognitive screening tests are available, such as the recently developed Early Mental Test and the standardised Mini-Mental State Exami - nation, Clock Drawing Test, which could help general practicioners in the recommended regular dementia screening. The aim of this review is to help general practicioners understand the nature and importance of prodromal and manifest stages of dementia syndromes, and to summarise the characteristics, advantages and disadvantages of dementia screening tests that can be used in primary care. In addition, practical hints are also integrated regarding the diagnosis, screening and referral of persons with high risk for dementia.]

[Current diagnostics and treatment of adolescent hypertension]

PÁLL Dénes, KATONA Éva, FÜLESDI Béla, JENEI Zoltán, POLGÁR Péter, PARAGH György, KAKUK György

[As the prevalence of hypertension in young people aged 14-18 is reported to be 1-1.5%, regular blood pressure measurement is proposed by the international committees in the adolescence, at least once a year. To establish the diagnosis of hypertension, repeated blood pressure measurements and sex-, age-, heightand weigt-based nomograms are needed. If casual blood pressures are consequently elevated, an ABPM measurement may provide additional informations, e.g. about white coat hypertension, daytime and nighttime blood pressure patterns and target organ damage. Thus, in such cases ABPM measurement is proposed to become the part of the routine examination. Following the diagnosis of hypertension in the adolescent, a further important step is to clarify the causes of the disease. In the majority of adolescent cases, essential hypertension is the diagnosis, but secondary (especially renal causes) are more frequent than in adulthood. First line treatment of adolescent hypertension is definitely non-pharmacologic. Pharmacologic treatment may be indicated if blood pressure is significantly increased (diastolic blood pressure, especially), if secondary hypertension is diagnosed or target-organ damage is present, or there are consistent complains related to the increased blood pressure. Treatment can be initiated with any of the antihypertensive drugs used in adults, but most frequently the use of beta-blockers and ACEinhibitors is recommended.]

[The Aim of the screening program was to investigate the blood pressure and the association with obesity, hypercholesterinaemia and increased body fluid in adolescents. Methods: A screening program was conducted during the period from April 2010 to May 2011.The screenings consisted of: blood pressure, heart rate, body composition determination, cholesterol, blood glucose, weight, height and BMI. Results: 2226 children fullfied all of the outlined criteria. Their range of age was between 14–18 years. The average systolic blood pressure was 126.34±12.55 Hgmm volt. At boys were higher 131.87±13.59 then at girls 117.49±5.69 Hgmm. The average diastolic blood pressure was 71.86±8.74 Hgmm. There were also higher at boys 72.61±9.17 then at girls 66.69±5.04 Hgmm. High systolic blood pressure (95%<) were 307/1326 cases at girls, and 403/876 cases at boys. High diastolic blood pressure were together with high systolic blood pressure, but less frequency. High diastolic blood pressure occurred at 85 girls and at 90 boys. Overweight and obes were 18.994% of girls and 15.26% of boys. The percentage of pathological high blood pressure was most frequent among boys and girls who are in the overweight group. The pathologically high level of body fat percentage appeared to be 12.98% among girls and 5.9% among boys. In elevated BMI groups the frequency of high body fat was 66% among girls and 81% among boys. The mean cholesterol was significantly higher in the overweight and obese group. Conclusions: Rates of hypertension and overweight and obesity are high in school children in Budapest, and increased bodyweight is a significant risk factor for hypertension. The results of the study will help to design preventive programmers.]
