[Acute gastrointestinal bleeding is a life threatening condition. Almost 90% of the acute bleeding episodes originate from the upper gastrointestinal tract with a 5-10% mortality rate. Emergency endoscopy is capable to detect the bleeding source offering the chance of endoscopic therapy as well. Injecting epinephrine in a 1:10000 diluted solution into the mucosa surrounding the ulcer is the generally used endoscopic haemostatic method. In ulcer bleeding cases permanent protonpump- inhibitor infusion for 72 hours is the therapy of choice to increase gastric pH and for the stabilization of the coagulum covering the ulcers. Mortality can be decreased by surgery performed in an early elective manner. The most important aim of gastroenterological treatment in ulcer bleeders is to avoid the rebleeding episodes which increase the mortality. Acute bleedings resulting from stress ulcers are typical complications in patients undergoing major surgery and require intensive care unit treatment. The mortality rate of stress ulcer bleeders can reach or even exceed 50%. Occasionally stress ulcers have a large ulcer like appearance but in most of the cases they have an erosive confluent formation. For the prophylaxis of the stress ulcer development and bleeding an effective inhibition of gastric acid secretion is recommended in the perioperative period as well as during the intensive care. Considering gastroenterological aspects protonpump- inhibition therapy offers the most effective protection of gastric mucosal barrier by increasing gastric pH. Despite sucralfate is being frequently used, the recommended stress ulcer prophylactic therapy is permanent PPI (pantoprazole or omeprazole) infusion in a dose of 8 mg/hours. With this prophylactic medication for 48-72 hours stress ulcers can be prevented in most of the cases without any significant adverse event.]

[LEGIONNAIRES’ DISEASE]

ROJKÓ Lívia

[Legionellae are important causative agents of nosocomial and community acquired pneumonias, the prevalence varying between 2-30%. The number of verified infections are increasing from year to year, which may be the consequence of the more sensitive and commonly applied laboratorical methods or can be explained by the spread of non-natural living environments created by humans. The outcome of Legionella infections are strongly determined by the host immune system, the comorbidities, the time to the diagnosis made and the initiated treatment. This review focuses on the various clinical manifestations of the Legionella infections, and summarises the diagnostic criteria and therapeutic methods in practice.]

[INTRODUCTION - The aim of this study is to analyse the local inequalities in the access and utilization of special home nursing within Hungary focusing on the South-Transdanubian Region. DATA AND METHODS - In the first part of the study we compared the indicators of the access and utilizations of special home nursing at national and county level. In the second part of the analyses we made a detailed analyses of utilization data of home nursing in the three counties (Baranya, Somogy, Tolna) of the South- Transdanubian Region of Hungary. Data is derived from the financial database of the National Health Insurance Fund of Hungary for the period 1998-2002. RESULTS - The access of population to the special home nursing increased from 83,8% (1998) to 95,1% (2002). The utilization rate increased from 74,8% (1998) to 84,1% (2002). Within the South-Transdanubian Region we found significant local inequalities in the utilization of services (number of cases, number of visits), which were represented by the tools of geographical information system. CONCLUSIONS - There have been significant differences in the access and utilization of home nursing with remarkable within country inequalities.]

[HANS SELYE 70 YEARS LATER: STEROIDS, STRESS ULCERS & H. PYLORI]

SZABÓ Sándor

[Although Hans Selye is mostly known for his discovery & development of the stress concept, he also introduced the first physiologically sound, structure-activity classification of steroids that was also based on the chemical structure of steroids in 1943. He not only introduced the names of glucocorticoids & mineralocorticoids but discovered the anti- & pro-inflammatory properties, respectively, of these steroids in animal models. Furthermore, he not only described the first stress-induced gastric ulcers in rats (1936) & characterized the first human ‘stress ulcers’ during the air-raids in London during World War II (1943). Thus, Selye was a much more productive & creative scientist than it is generally considered.]

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.

[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.]
