Lege Artis Medicinae - 2006;16(06)

[PEG (percutaneous endoscopic gastrostomy) has by now become a widely used method, especially to ensure long-term enteral nutrition. In developed countries nearly 1 in 1000 people have a PEG. Although the use of PEG increases year by year in Hungary, it is still performed too rarely or too late. PEG is an invasive but simple endoscopic technique that may be carried out even at the patient's bed. In cases when the routinely used oral route for oesophago-gastro-duodenoscopy is impossible one of the following alternative ways can be chosen: endoscopy via a laryngoscope, through the opened pharynx, through a large pharyngo-oesophageal fistula or transnasally. These allow the bypassing of stenoses and the placement of PEG. There are few absolute contraindications and complications occur rarely. Early treatment and follow-up of dermatitis is important since it may be the first sign of severe complications. PEG tubes may function for many years with proper maintenance. Feeding via PEG tubes is especially effective in head and neck malignancies or injuries and in neurological disorders. In surgery it can be used for the management of surgical complications or for decompression of the stomach and duodenum. PEG-feeding is common in geriatrics and in paediatrics, sometimes with questionable indications. If used with adequate indications, ethical considerations, wise forethought, and a decision made together with the patient and family, PEG may improve lifespan and quality of life, decrease complications and side effects of the therapy and owing to its cosmetic benefits it facilitates re-socialisation.]

[AUTOIMMUNE PANCREATITIS - AN UNDERDIAGNOSED DISEASE?]

CZAKÓ László

[Autoimmune pancreatitis is a recently recognized type of chronic pancreatitis that is clearly distinct from alcoholic chronic pancreatitis. Its clinical symptoms include jaundice, abdominal pain, weight loss and diabetes mellitus. It may be associated with other autoimmune diseases. IgG levels are elevated and autoantibodies can be detected. Pancreatic imaging reveals a diffuse enlargement of the pancreas and irregular narrowing of the main pancreatic duct. The characteristic histological features are lymphoplasmacytic infiltration and fibrosis. Autoimmune pancreatitis responds dramatically to steroid therapy, in contrast to other types of chronic pancreatitis, which hardly respond to any of the various therapies. It is important to be aware of this disease because it may be mistaken for other forms of chronic pancreatitis or pancreatic cancer, which leads to pancreatic resection when steroid treatment would be sufficient. This review discusses the clinical, laboratory, histological and imaging findings that are seen in autoimmune pancreatitis with particular focus on diagnosis. With the improvement of the diagnostic work-up less unnecessary pancreatic resections are expected to happen in patients with autoimmune pancreatitis.]

[ENDOTHELIAL DYSFUNCTION IN DYSLIPIDAEMIA - THE ROLE OF THE RENIN-ANGIOTENSIN SYSTEM]

FARKAS Katalin

[Dyslipidaemia is one of the known main risk factors of atherosclerosis by causing endothelial dysfunction that initiates and promotes vascular remodelling. Recent data from experimental and clinical studies suggest the existence of lipoprotein- neurohormonal interactions that may adversely affect vascular structure and function. Elevated lipid levels enhance the activation of the renin-angiotensin system, and, on the other hand, activation of the renin-angiotensin system leads to increased LDL cholesterol biosynthesis and oxidized-LDL uptake. These findings may explain the synergistic effect on cardiovascular risk observed in patients with coexisting hypertension and dyslipidaemia. The combined use of cholesterol-lowering drugs and inhibition of the tissue renin-angiotensin system may be more efficient in reducing cardiovascular risk.]

[FUTURE CARRIER AND FAMILY PLANS OF 5TH-YEAR FEMALE MEDICAL STUDENTS]

FEITH Helga Judit, KOVÁCSNÉ Tóth Ágnes, BALÁZS Péter

[INTRODUCTION - The aim of this study was to analyze female medical students' carrier and family attitudes and plans in view of two social problems: (1) the increasing shortage of physicians in Hungary and (2) conflicts and health problems in the life of female doctors caused by professional and family duties. METHOD - The basis of this study is a selfreported questionnaire-based survey performed in the spring of 2004 among 5th-year female medical students in the faculties of general medicine at Semmelweis and Debrecen universities. One hundred and seventeen students (46.2%) responded. RESULTS - The overwhelming majority of students (91.5%) want to work as a physicians, and 63.5% plan to work abroad in health care. As to family planning, 95.7% of the respondents would like to have children, although only 52.8% plan to stay at home in the first three years. CONCLUSION - These data suggest that the majority of Hungarian female medical students want to be engaged in the medical profession and plan to meet both family and career demands. Due to its special requirements, however, this profession may generate future marital, childmother relationship and workplace conflicts.]

GYÖKERES Tibor, KIRÁLY Ágnes, LAKATOS László, MADÁCSY László

[This paper reviews the current knowledge on the association of obesity and gastrointestinal disorders. While the relationship between obesity and cardiovascular disorders has recently gained wide professional publicity, there are few data on the gastroenterological aspects of obesity. After a discussion on obesity as an epidemic, its international and national prevalence, and public health risks, the most common obesity-related gastrointestinal disorders, their incidence, pathomechanism and consequences are presented by the organ systems affected, including gastrooesophageal reflux disease, fatty liver, gallstone disease, diseases of the pancreas, and colorectal carcinoma. Finally, the means of prevention and treatment are summarized.]

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 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.]

[Second game, 37th move and Fourth game 78th move]

[What has Go to do with making clinical decisions? One of the greatest intellectual challenges of bedside medicine is making decisions under uncertainty. Besides the psychological traps of traditionally intuitive and heuristic medical decision making, lack of information, scarce resources and characteristics of doctor-patient relationship contribute equally to this uncertainty. Formal, mathematical model based analysis of decisions used widely in developing clinical guidelines and in health technology assessment provides a good tool in theoretical terms to avoid pitfalls of intuitive decision making. Nevertheless it can be hardly used in individual situations and most physicians dislike it as well. This method, however, has its own limitations, especially while tailoring individual decisions, under inclusion of potential lack of input data used for calculations, or its large imprecision, and the low capability of the current mathematical models to represent the full complexity and variability of processes in complex systems. Nevertheless, clinical decision support systems can be helpful in the individual decision making of physicians if they are well integrated in the health information systems, and do not break down the physicians’ autonomy of making decisions. Classical decision support systems are knowledge based and rely on system of rules and problem specific algorithms. They are utilized widely from health administration to image processing. The current information revolution created the so-called artificial intelligence by machine learning methods, i.e. machines can learn indeed. This new generation of artificial intelligence is not based on particular system of rules but on neuronal networks teaching themselves by huge databases and general learning algorithms. This type of artificial intelligence outperforms humans already in certain fields like chess, Go, or aerial combat. Its development is full of challenges and threats, while it presents a technological breakthrough, which cannot be stopped and will transform our world. Its development and application has already started also in the healthcare. Health professionals must participate in this development to steer it into the right direction. Lee Sedol, 18-times Go world champion retired three years after his historical defeat from AlphaGo artificial intelligence, be­cause “Even if I become the No. 1, there is an entity that cannot be defeated”. It is our great luck that we do not need to compete or defeat it, we must ensure instead that it would be safe and trustworthy, and in collaboration with humans this entity would make healthcare more effective and efficient. ]

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.
