[The possibilities of CT and MR imaging in hydrocarbon research]

BOGNER Péter, FÖLDES Tamás, ZÁVODA Ferenc, REPA Imre

[INTRODUCTION - Cross-sectional medical imaging techniques were applied on geological samples (cores) in order to reveal their morphological and functional properties. Our aim was to reveal those CT and MRI methods that are capable to characterize certain petrophysical parameters and can be correlated with core morphology. MATERIALS AND METHODS - Similarly to pre- and postcontrast scanning in human diagnostic imaging CT scans of core samples were obtained in dry and flooded state, that helped to define and calculate morphological and functional parameters. Several MRI sequences were also tested, mainly spin-echos with short echo time. RESULTS - Several hundred meters of core samples have been examined in the last three years. Effective porosity can be calculated from CT data, that characterizes oil/gas storage capacity of the given geological formation. CT information is superior to conventional petrophysical methods due to its spatial resolution. Nevertheless, we can not quantify permeabilty yet, but describe it qualitatively. We found only limited use of medical MR imaging methods. DISCUSSION - Cross-sectional imaging, primarily CT scanning was introduced to the Hungarian oil and gas industry in the last three years. It seems that the method will be used more and more frequently through the entire process of oil/gas exploitation. Our further goals include the implementation of the CT measurements in other areas like environment control, and further develope measurement conditions.]

[Ultrasound is not a stetoscope]

HARKÁNYI Zoltán

[Introduction of the small size, portable ultrasound machines opened new opportunities in ultrasound imaging. The optimal application of these equipments and the new problems related to the use are widely discussed in the literature. This brief review summarizes the advantages, main indication and limitations of the method. The single most important aspect for the patient is that emergency ultrasound examination should be available regardless of the profession of the doctors. The most difficult question is how to provide and control an optimal education and training for the doctors. Possible solutions are also discussed. It is predictable that the availablity of the portable ultrasound studies will significantly increase the number of examinations, therefore economical consequences must also be considered. The author disagree with the conception, which states that ultrasound machine can be used as a stetoscop in the doctor's pocket.]

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

[Vaccines against COVID-19 pandemic]

FALUS András, SZEKANECZ Zoltán

[The rapidly spreading SARS-CoV2 respiratory virus has evoked an epidemic with serious aftermath around the world. In addition to the health effects, the global economic damage is actually unpredictable. At the same time, the pandemic has launched a series of unprecedented collaborative scientific research, including the development of vaccines. This study summarizes up-to-date information on vaccines, immune memory, and some emerging clinical effects.]

[A short chronicle of three decades ]

KAPRONCZAY Katalin

[Hungarian professional periodicals started quite late in European context. Their publish­ing, editing and editorial philosophy were equally influenced by specific historical and political situations. Certain breaking points of history resulted in termina­tion of professional journals (War of In­de­pendence 1848-1849, First and Se­cond World Wars), however there were pe­riods, which instigated the progress of sciences and founding of new scientific journals. Both trends were apparent in years after the fall of former Hungarian regime in 1990. The structure of book and journal publishing has changed substantially, some publishers fell “victim” others started successfully as well. The latters include the then-established publishing house Literatura Medica and its own scientific journal, Lege Artis Me­di­cinae (according to its subtitle: New Hun­garian Medical Herald) issued first in 1990. Its appearance enhanced significantly the medical press market. Its scientific publications compete with articles of the well-established domestic medical journals however its philosophy set brand-new trends on the market. Concerning the medical community, it takes on its problems and provides a forum for them. These problems are emerging questions in health care, economy and prevention, in close interrelation with system of public health institutions, infrastructure and situation of those providing individual health services. In all of them, Lege Artis Medicinae follows consequently the ideas of traditional social medicine.]
