[The use of adequate imaging protocol reduces morbidity and mortality in emergency cases of pregnant women. The least harmful, but sufficiently informative imaging method should be chosen that provides us with the diagnosis in the shortest delay. Although the reduction of harmful effects is important, life threatening complications can be avoided by an indicated and well effectuated imaging method using ionizing radiation.]

[Pulmonary abnormalities in haematological malignancies - The role of imaging in differential]

GYŐRI Gabriella, MAGYAR Péter, KOVÁCS Balázs, BÉRCZI Viktor, BALASSA Katalin, DEMETER Judit

[Patients with hematological malignancies may develop a wide range of pulmonary abnormalities due to the hematological disease itself as well as in response to therapy. Immunosuppression and intensive chemotherapy induced severe neutropenia hold a high risk of infection. Infectionrelated morbidity and mortality are still high. One of the most common infectious complications is invasive mycosis, which is lethal in a high percentage of cases if not treated immediately and adequately. Non-infectious complications, such as secondary pulmonary lymphoma, thromboembolism, hemorrhage or drug induced fibrosis may develop during the course of the disease. Sometimes it is difficult to make a definitive diagnosis. As invasive methods (bronchoscopy, bronchoalveolar lavage, biopsy) are mostly contraindicated in these patients with severe neutropenia and thrombocytopenia, imaging techniques are especially important. It is a great challenge to differentiate infectious and noninfectious processes. CT and HRCT play an essential role in differential diagnosis. An early and accurate diagnosis is sometimes the only chance for survival.]

[Purpose - The scientific study of Pál Széchényi’s mummy was carried out by our research team composed of the members of several institutions in 2007 April. The scientific examinations represented a milestone, since up till now it was unclear whether it was a natural or artificial mummy and the century-old question whether Pál Széchényi was in fact a victim of arsenic poisoning in 1710 or it was only a legend could also be answered. Methods - The non-invasive examinations were carried out with multislice CT, traditional X-ray, biopsy, toxicology, energy-dispersive X-ray, X-ray fluorescens analysis, 3D optical digitalization indicator system, endoscope and 3D rapid-prototyping printing. Results - The examinations proved that Archbishop Pál Széchényi’s death was natural, and his body was artificially mummified. The CT examinations were carried out in a slice thickness of under 1 mm facilitating printed skull copy made by 3D rapid-prototyping method which provided the exact and detailed basis for the facial reconstruction.]

[Family planning in multiple sclerosis: conception, pregnancy, breastfeeding]

RÓZSA Csilla

[Family planning is an exceptionally important question in multiple sclerosis, as women of childbearing age are the ones most often affected. Although it is proven that pregnancy does not worsen the long-term prognosis of relapsing-remitting multiple sclerosis, many patients are still doubtful about having children. This question is further complicated by the fact that patients – and often even doctors – are not sufficiently informed about how the ever-increasing number of available disease-modifying treatments affect pregnancies. Breastfeeding is an even less clear topic. Patients usually look to their neurologists first for answers concerning these matters. It falls to the neurologist to rationally evaluate the risks and benefits of contraception, pregnancy, assisted reproduction, childbirth, breastfeeding and disease modifying treatments, to inform patients about these, and then together come to a decision about the best possible therapeutic approach, taking the patients’ individual family plans into consideration. Here we present a review of relevant literature adhering to international guidelines on the topics of conception, pregnancy and breastfeeding, with a special focus on the applicability of approved disease modifying treatments during pregnancy and breastfeeding. The goal of this article is to provide clinicians involved in the care of MS patients with up-to-date information that they can utilize in their day-to-day clinical practice. ]

[The radiohygienic aspects of the interventional radiology]

PELLET Sándor, GICZI Ferenc, GÁSPÁRDY Géza, TEMESI Alfréda

[Interventional radiology is a relatively new and very rapidly developing cost-effective branch of radiology. Its aim to help or to replace surgical procedures and interventions in many cases are life saving, which are performed by imaging modality control (most commonly angiography or fluoroscopy). During interventional radiological procedures the exposure of staff and patients is usually higher, than in conventional radiography or fluoroscopy. Deterministic effects may also occur. The dosimetry can be carried out by film dosimetry, thermoluminescent dosimetry, DAP meters, semiconductor detectors and personal electronic dosimeter. The basis of reduction of radiation exposure is the radiation protection training. An important rule is that reduction of patient exposure is connected with reduction of staff exposure. With the use of appropriate tools and training the most injuries are avoidable.]

JÁRAI Zoltán, VÁRBÍRÓ Szabolcs

[Hypertension complicates approximately 10% of the pregnancies and with this high blood pressure is the most frequent cardiovascular comorbidity during pregnancy. Hypertension during pregnancy accounts for a substantial maternal and perinatal morbidity and mortality risk. In our review we focus on the forms, diagnosis and therapeutic possibilities of gestational hypertension according to the European and domestic guidelines.]

[Even in the absence of clinically signifi cant co-morbidities, cancer care is a major challenge for both patients and healthcare professionals. Routine anticancer treatment may be complicated by special clinical situations such as pregnancy or organ transplantation. The dosage of certain oncotherapy agents may be further affected by impaired renal and hepatic function or diabetes mellitus. These days, given the improved prognosis of cancerous diseases and increased survival, personalized therapy and prevention of long-term side effects is becoming particularly important, especially in the above-mentioned oncological situations. In this summary, we review the anticancer treatments recommended by ESMO in specifi c clinical situations.]

[Menopause and pregnancy are especially vulnerable periods of women’s life regarding hypertension. The “Guidelines for the Management of Arterial Hypertension”, issued by the European Society of Hypertension and the European Society of Cardiology, dedicates a separate chapter to hypertension in women. The renewed guidelines of the Hungarian Society of Hypertension also pays a special attention to hypertension detected during pregnancy. In this article, the euthors review the topics of hypertension detected during menopause and pregnancy, discussing pathomechanism and therapy.]
