[Radiology of pancreas: review from the last year - Gastro Update 2007]

FORRAI Gábor

[PURPOSE - To demonstrate the recent results in radiological diagnostics of pancreas, and the actual place of the imaging and interventional methods. METHOD - Systematic review of the most recent articles from the last year in the following subjects: acute, chronic and autoimmune pancreatitis, pancreatic cancer and other tumors, PET and special imaging problems in pancreas transplantation. RESULTS - Annually, experience in pancreatic diagnostical methods are accumulating rapidly. Therefore, there is a continuous change in the examination algorithm with new diagnostic and therapeutic modalities making their way into the daily routine. Some of the algorithms become obsolete within a few years and their further application is considered mismanagement. Some other methods become obligatory steps in the diagnostics. These are the reasons why up-to-date knowledge of the literature is mandatory.]

[Role of contrast enhanced ultrasound in clinical practice]

HARKÁNYI Zoltán

[Ultrasound contrast agents consist of micro bubbles which can be visualized during their short intravascular and parenchymal transit time. An US system with special software, a small amount of intravenous contrast agent and a skilled operator is necessary to produce a successful study. This method can also be introduced into the clinical practice in our country. Careful indications and well performed studies can reduce the number of unnecessary CT and MR studies and biopsies. Contrast enhanced US has special clinical significance in the detection and characterization of focal liver masses, monitoring drug and local treatment effects of different abdominal tumors and in the case of injury of abdominal parenchymal organs.]

[Evaluation of cystic renal masses with MDCT]

BATA Pál, MIKUSI Regina, KARLINGER Kinga, BÉRCZI Viktor, SZENDRŐI Attila, ROMICS Imre

[Modern CT and MRI scanners can give an exact and rapid diagnosis in the case of most cystic renal masses. Dilemma in their diagnosis is whether or not the changes need surgical intervention. The question of follow-up is decided with the use of the Bosniak classification. To characterize the cystic changes excellent quality, multiphasic MDCT examination is necessary with the following parameters: 80-120 mls. of non-ionic iodinated intravenous contrast material given with an injector at 3 ml/sec flow-rate with saline flush technique, unenhanced and post-contrast scans obtained at 35 and 70 seconds, with more scans at 120-300 seconds, as deemed necessary. A collimation of 16x1.5 mm with an overlap of 50% should be aimed for. Through the primary data we perform a reconstruction of 2 mm, with an option to create volume-rendered image sin the post-processing phase, as necessary. With the help of this CT protocol we can measure the different criterions of Bosniak classification in the cystic masses like minimal, smooth or irregular wall thickening, with or without enhancement. We can recognize hairline thin or thickened septa, fine or irregular (thick or nodular) calcifications, solid component with or without contrast enhancement. Using these criteria each cystic mass can be assigned to a Bosniak cystic category (I, II, IIF, III and IV)]

[High resolution sonography for the examination of peripheral nerves]

JOSEF Böhm

[High-frequency sonography is an important method for the imaging of the peripheral nerves, even though it is rarely used. For the examination of superficially located nerves, currently available transducers with frequencies between 12-17 MHz offer a better axial resolution than even MRI. Sonography is superior to MRI especially for the examination of nerves of the upper extremity. Main indications for the sonography of the nerves are entrapment syndromes, traumatic injuries of the nerves, tumors, polyneuropathies and sonographically-guided interventions. The sensitivity of sonography and electrophysiology in the diagnosis of carpal tunnel syndrome and cubital tunnel syndrome are comparable. The combination of ultrasonography with electrophysiological studies increases the diagnostic yield in carpal and cubital tunnel syndromes. Sonography provides information for planning of peripheral nerve surgery and is helpful in evaluating postoperative complications. In selected cases, sonography can detect nerve lesions that require operative therapy earlier than electrophysiology. With technical enhancements, highfrequency ultrasonography is gaining increasing importance in the routine diagnostics of peripheral nerves lesions.]

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

JARABIN András János, KLIVÉNYI Péter, TISZLAVICZ László, MOLNÁR Anna Fiona, GION Katalin, FÖLDESI Imre, KISS Geza Jozsef, ROVÓ László, BELLA Zsolt

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

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

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[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]

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. ]

[Focus on Lege Artis Medicinae (LAM)]

VASAS Lívia, GEGES József

[Three decades ago, LAM was launched with the goal of providing scientific information about medicine and its frontiers. From the very beginning, LAM has also concerned a special subject area while connecting medicine with the world of art. In the palette of medical articles, it remained a special feature to this day. The analysis of the history of LAM to date was performed using internationally accepted publication guidelines and scientific databases as a pledge of objectivity. We examined the practice of LAM if it meets the main criteria, the professional expectations of our days, when publishing contents of the traditional printed edition and its electronic version. We explored the visibility of articles in the largest bibliographic and scientific metric databases, and reviewed the LAM's place among the Hun­ga­rian professional journals. Our results show that in recent years LAM has gained international reputation des­pite publishing in Hungarian spoken by a few people. This is due to articles with foreign co-authors as well as references to LAM in articles written exclusively by foreign researchers. The journal is of course full readable in the Hungarian bibliographic databases, and its popularity is among the leading ones. The great virtue of the journal is the wide spectrum of the authors' affiliation, with which they cover almost completely the Hungarian health care institutional sys­tem. The special feature of its columns is enhanced by the publication of writings on art, which may increase Hungarian and foreign interest like that of medical articles.]

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.
