[Emergency imaging in pregnant women]

BORBÉLY Krisztina, KATHIA Chaumoître, FORRAI Gábor

[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.]

[Differential diagnosis of malignant cervical lymph nodes with real-time ultrasonographic elastography and Doppler ultrasonography]

[PURPOSE - Real-time ultrasonographic elastography is a new imaging technique which is used in characterizing the difference in hardness between pathologic and normal tissue. The purpose of our study was to evaluate the diagnostic performance of real-time ultrasonographic elastography and Doppler ultrasonography (DUS) individually and combined in differentiation of benign and malignant cervical lymph nodes (LN). PATIENTS AND METHODS - Fifty-one patients (12 men, 39 women) referred for fine-needle aspiration or surgical biopsies of suspected cervical lymph nodes were examined with gray scale ultrasonography, power DUS, and realtime ultrasonographic elastography. During DUS examination vascularity and resistance index (RI) values were evaluated. A five-group elastographic colour code pattern was used to evaluate the ultrasonographic elastograms for LN (pattern 1, an absent or a very small hard area; pattern 2, hard area <45%; pattern 3, hard area ≥45%; pattern 4, peripheral hard and central soft areas; pattern 5, hard area occupying entire solid component with or without soft rim). In addition, strains of LN and surrounding muscles were measured on elastograms, and the muscle-to-LN ratio (strain index) was calculated. Real-time ultrasonographic elastography and DUS results were compared with the final diagnosis obtained by fine-needle aspiration cytology analysis and/or by surgical pathology. The diagnostic potential of the examined criteria for malignancy was evaluated with univariate analysis and multivariate generalized estimating equation regression p≤0.05 indicated statistical significance. RESULTS - A strain index higher than 2.45 and colour pattern 4-5 had high utility in malignant LN classification with 93.8% sensitivity, 89.5% specificity (p<0.001). The results were significantly better than those obtained by using DUS characterization - that is, RI greater than 0.57 - which had 78.9% sensitivity (p<0.001). CONCLUSION - Real-time ultrasonographic elastography had 93.8% sensitivity and 89.5% specificity in the differentiation of benign and malignant cervical LN in patients referred for fine-needle aspiration or surgical biopsies with suspicion of malignancy. Real-time ultrasonographic elastography and DUS in addition to gray scale ultrasonography may improve the differential diagnosis of LN.]

[Interdisciplinary mummy research - Paleoradiology and paleopathology research of the Archbishop of Kalocsa Pál Széchényi’s mummy]

KRISTÓF Lilla Alida, POHÁRNOK László, KERÉNYI Tibor, TÓTH Vilmos, ISTÓK Roland, HARGITTAI Péter, FORNET Béla, PAP Ildikó, PÁLFI György

[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.]

Neurocognitive functions in patients with hepatitis C infection

HORVÁTH Gergely, KELETI Teodóra, MAKARA Mihály, UNGVARI S Gabor, GAZDAG Gábor

Background - With improving treatment options, more attention is being paid to the neurocognitive symptoms related to hepatitis C infection (HCI). While HCI-related neurocognitive impairments are frequently subclinical, they can influence patients’ quality of life and fitness to work. Objective - The aim of this study was to assess HCI patients’ neurocognitive functions and explore the correlations between disease variables and neurocognitive symptoms. Method - The study was conducted between January 1, 2013 and December 31, 2015. All patients with HCI were included in the study who were registered at the Hepatology Outpatient Clinic of Szent István and Szent László Hospitals, met inclusion criteria and volunteered to participate. Patients’ sociodemographic data and medical history were recorded in a questionnaire designed for the study. The 21-item Beck Depression Inventory was used to detect depressive symptoms. Six computerized tests were used to evaluate patients’ neuropsychological functions. Results - Sixty patients participated in the study. In comparison with general population standards, patients demonstrated poorer performance in several neurocognitive tests. Neuropsychological performance was correlated with age, sex, length of time since HCI diagnosis, Fibroscan score and the number of previous antiviral treatments. Conclusions - The study’s main finding is that compared to general population standards, patients with hepatitis C virus-related disease exhibit impaired neuropsychological functioning in visuomotor and visuospatial functions, working memory, executive functions, and reaction time. Executive functions and reaction time were the most sensitive indicators for the length and severity of disease. Deterioration in these functions has a major negative effect on work performance particularly in certain occupations.

[Prominents in Hungarian nephrology Professor Gyula Petrányi (1912-2000). Part II]


[A nation can only survive and keep its identity through its traditions. This is why the initiative to launch this series coming from professor János Radó is worthy of attention. Gyula Petrányi is an outstanding personality in 20th century internal medicine, to be more precise in nephrology and immunology, his activity being wide-ranging. The first part of the current summary of his work deals with a tribute to his personality, and his role in immunomodularity treatment in glomerulonephritis. The second part shall cover his role in spreading renal biopsy, screening and caring kidney patients, dialysis, in developing kidney patients’ care, furthermore in clinicopharmacology and renal transplantation.]
