[8th Hungarian Congress on AlzheimerAbstracts]

[Despite of the now well-recognised importance of trace elements in medical field - it is established that several diseases of the central nervous system, like Alzheimer’s disease are connected to alterations of trace elements levels - reliable data on their concentrations in normal and pathological human brain are still rare. Correlation studies are even more scarce in the literature, especially in case of Alzheimer’s disease.]

[Functional imaging of cerebrospinal fluid pathology]

BORBÉLY Katalin

[The most common problem addressed by dynamic radionuclide imaging of cerebrospinal fluid (CSF) abnormalities is differentiating patients with normal-pressure hydrocephalus (NPH) from those with other forms of degenerative brain disorder who would clearly not benefit from surgical treatment by ventricular shunting. Radionuclide cisternography (RC) SPECT and regional cerebral blood flow (rCBF) SPECT are critically important for the diagnosis and therapy management of patients with chronic hydrocephalus. However, radionuclide imaging is helpful not only in identifying patients with NPH showing improvement after shunting. RC reveals tracer activity outside the intracranial cavity, indeed. The importance of establishing the diagnosis arises from the fact that untreated leaks can be followed by meningitis in up to one quarter of patients. CSF collections may communicate with the subarachnoid space. RC SPECT has proved useful in assessing the communication of the arachnoid cysts (CSF collection) with the ventricular or subarachnoid compartment. Improved anatomical detail revealed by SPECT imaging is helpful in solving problems of the CSF pathology. Sensitive and accurate assessments of normal and disordered CSF dynamics can be obtained with RC SPECT.]

[Traumatic prepontine tension pneumocephalus (in English language)]

KUNCZ Ádám, ROOS Arne, LUJBER László, HAAS Daniella, REFAI Al Mohamed

[Objective - A case of prepontine tension pneumocephalus after temporal bone fracture is presented. Case report - An 8-year-old girl suffered a head injury due to a fall off her bicycle. She lost her consciousness, and when she was admitted to the local hospital the Glasgow Coma Score (GCS) was 8/15 (eye opening: 2; verbal answer: 2; motor response: 4) and there was bleeding from the right ear. The patient's condition deteriorated rapidly and she needed intubation and ventilation. CT of the brain revealed large amount of air in the prepontine region, displacing the brainstem posteriorly. Patient was kept ventilated, meanwhile cerebrospinal fluid (CSF), as otorrhea appeared on the right side. CT was repeated 36 hours later, showing significantly less air in the prepontine area. The patient was weaned off the respirator, extubated and the level of consciusness improved. Later the patient developed meningitis, which was treated by systemic antibiotics with lumbar CSF drainage applied for five days. A high resolution CT scan of the petrous bone revealed a fracture crossing the middle part of the pyramid. Patient showed a full recovery except a right-sided mixed hearing loss. Conclusion - Rapid neurological deterioration following head injury can be a consequence of tension pneumocephalus. Prepontine pneumocephalus can be caused by minor fracture of petrous bone. High resolution CT is necessary to visualize minor fracture of the petrous bone. Conservative treatment may be satisfactory to treat tension hydrocephalus.]

[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. ]

[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.]

[History of vaccine production in Hungary ]

ÓCSAI Lajos

[This study presents the complete history of the Hungarian vaccine production, partly in association with the process of fighting vaccine-preventable infectious diseases, and underlines the fact that every government actively contributed to the age-adjusted mandatory vaccination schedule of the past 140 years. It demonstrates the various achievements from the smallpox lymph production through the launch of diphtheria serum production at Phylaxia and the establishment of the National Public Health Institute (OKI) with its vaccine production and the later institutional transformation of OKI into Humán as economic corporation to its closure. Among all OKI’s vaccine production activities, this study focuses on the production of influenza vaccines, due to its international importance in the 1960s and 1970s. The vaccine production against diphtheria tetanus and pertussis stands out from Humán’s activities, and the tetanus component of this vaccine is still used in the products of a multinational vaccine manufacturer. ]

[Diagnosis and treatment of microvascular coronary heart disease. Specialities of conditions in Hungary]

SZAUDER Ipoly

[Invasive investigations show that in two-thirds of patients the myocardial ischaemia persists without obstructive coronary disease and any other heart conditions (INOCA). The underlying cause may be microvascular dysfunction (CMD) with consecutive microvascular coronary disease (MVD) and microvascular or epicardial vasospastic angina (MVA). The modern practice of clinical cardiology while using the developed non-invasive cardiac imaging permits exact measuring of the coronary flow with its characteristic indices. All of these improve the diagnosing of CMD-induced myocardial ischemia and provide opportunity to determine primary MVD cases. Since the recognition and treatment of MVD is significantly underrep­resented in the Hungarian medical care, the primary stable microvascular angina (MVA) is described in detail below with its modern invasive and non-invasive differential diagnosis and treatment, concerning especially its frequency provoked by high blood pressure and female coronary heart diseases. There are highlighted all recommended diagnostic procedures available under domestic conditions.]
