[Gastrointestinal stromal tumors]


[Gastrointestinal stromal tumors are the most common mesenchymal neoplasm of the gastrointestinal tract. Gastrointestinal stromal tumors are characterized by remarkable variability in their differentiation potential. They are defined by their expression of KIT (CD117), a tyrosine kinase growth factor receptor. The expression of KIT is important to distinguish gastrointestinal stromal tumors with immunohistochemically method from other mesenchymal neoplasms such as leiomyomas, leiomyosarcomas, leiomyoblastomas and schwannomas. Pathologically proved gastrointestinal stromal tumors are appropriate KIT-inhibitor therapy. Gastrointestinal stromal tumors arise with variable frequency throughout the gastrointestinal tract, they most frequently occur in the stomach (40-70%), followed by the small intestine (20-30%), colorectum (5- 15%) and esophagus (<5%). The most gastrointestinal stromal tumors arise within the muscularis propria, they most commonly have an exophytic growth pattern and manifest as dominant extraluminal masses. Radiologic features of gastrointestinal stromal tumors vary depending of tumor size and organ of origin. They are characteristically well circumscribed, sharply defined and have hemorrhage, necrosis or cyst formation. The radiologic features of gastrointestinal stromal tumors are often distinct from those of epithelial tumors. There are no specific radiologic features to separate gastrointestinal stromal tumors from other mesenchymal tumors, yet.]

[Esophageal diverticula in mixed connective tissue disease]

SZÁNTÓ Dezső, SZŰCS Gabriella, DITRÓI Edit

[INTRODUCTION - The functional and morphological changes of oesophagus occur in two third of mixed connective tissue disease patients according to the literature. CASE REPORT - We report three cases of 27, 39 and 48 year old women suffering of lateral pharyngoesophageal, epibronchial and epiphrenic diverticula associated with connective tissue disease. Diverticula had an average diameter of 3.8 cm (maximal diameters: 7.2-8 cm). The esophageal pouches produced dysphagia, dystonia, motility disorders, food stagnation and vomiting, retrosternal burning sensation and tachyarrythmia after 5-16 month's latency period. In one patient pneumoesophagus also evolved. The high serum enzyme levels and proximal electromyogram proved the presence of polymyositis. CONCLUSION - The localization, number and the size of esophageal diverticula are determined by the interstitial myopathy.]

[Basics and methods of radiostereometric analysis in orthopaedic practice]

ILLYÉS Árpád, KISS Rita M., KÖLLŐ Katalin, KISS Jenő

[Photogrametry is a discipline processing geometric information of images according to the general image concept. Radiostereometric analysis (Roentgen stereophotogrametric analysis) is the most dynamically developing area of the orthopaedic photogrametry. The aim of the authors was to summarize the different methods of radiostereometric analysis in use. Two basically different methods are used: marker-based and model-based radiostereometric analysis. The authors summarize and compare the steps, the advantages and the disadvantages of either method. Radiostereometric analysis is because of its high precision appropriate as a tool in scientific research and diagnostic in orthopaedics, such as detecting the 3D micromotion of different components of implants, the wear of polyethylene inserts or determining anterior-posterior and rotational movements of the knee. Analyzing the reproducibility and accuracy of the reconstruction methods one can establish that the accuracy of analytical methods in use is behind the accuracy of digital automated software. The precision of the model-based radiostereometry can never achieve the accuracy of the marker based radiostereometry because of the inaccuracy of the initial input model of implants, although the one of the method of reversed engineering - one of model-based radiostereometric analysis - can approach the accuracy of marker-based radiostereometry.]

[Solitary fibrous tumor of the chest]

AGÓCS Ágnes, KISHINDI KISS Katalin, PENCS Mónika, TÓTH Tivadar

[INTRODUCTION - Solitary fibrous tumor is a rare, in most of the cases benign tumor of mesenchymal origin arising from the pleura. CASE REPORT - Significantly raised right hemidiaphragm was noted on the chest X-ray of an elderly female patient with good general condition. A large solid mass lesion was seen above the normally positioned right hemidiaphragm on ultrasound and chest CT examinations. The mass was removed by surgical resection and a solitary fibrous tumor was confirmed by histological and immunhistochemical examinations. CONCLUSION - Solitary fibrosus tumor is a rare and histologically benign tumor. Occasionally it may enlarge rapidly and transform into malignant variant after several years. Therefore complete surgical resection and long term follow up is needed in all cases.]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[The connection between the socioeconomic status and stroke in Budapest]


[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[The Comprehensive Aphasia Test in Hungarian]


[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. ]

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.
