[Laboratory control of the oral anticoagulant therapy]

VAJDA Zoltán, PÁL András, SIKOS Zita, SAS Géza

[There are two basic requirements in the treatment and prophylaxis of thromboembo lic diseases by chronic anticoagulation with coumarin (Syncumar). The first is the preven tion of a new thrombosis while the second is the avoidance of concomitant bleeding complications. For this reason it is necessary to achieve an appropriate anticoagulation level which can be characterised by labora tory measurement of the prothrombin level. In this paper, the theoretical and practical as pects of the laboratory control of Syncumar treatment are reviewed. The most serious problem is that the prothrombin level (Quick time) determinations utilising thromboplastin preparations from different sources give diffe rent values in the same patient plasma, which makes comparison of data from different laboratories impossible. The paper gives a brief overview of the definition and practical use of the International Sensitivity Index (ISI), characterising the different thromboplastin preparations, and the International Normali sed Ratio (INR) which can be calculated on the basis of the ISI. In spite of unquestionable improvements, the uncertainty about instrument-thromboplastin-ISI relationships reduces confidence in the INR system, especially when differences in INR values have clinical significance. Efforts need to be directed toward providing local, laboratory/instrument specific ISI values. ]

[The clinical significance of amaurosis fugax]

HORVÁTH Sándor, SOMLAI Judit

[The symptoms of amaurosis fugax (transient monocular loss of vision) indicate not only atherosclerotic disease of the ocular or extra cranial cerebral vessels, but also that of the systemic circulation. The prognostic significance of amaurosis fugax developing after the age of 50-55 years is similar to that of transient ischaemic attack of the brain: it could be a harbinger of atherosclerotic disease of the extra- and intracranial brain vessels as well as the coronary arteries. According to the mortality data, patients presenting with symptoms suggestive of amaurosis fugax will die due to heart disease, primarily myocardial infarct. Diagnostic evaluation should include not only ophthalmological, but also neurological and cardiovascular in vestigation to verify carotid and coronary atherosclerosis. Therapy of the whole disease and not just the symptoms will influence life expectancy in patients with amaurosis fugax. ]

[Methylprednisolone pulse therapy in systemic lupus erythematosus]

GERGELY Péter

[The aim of this retrospective study was to assess the efficacy and safety of methylprednisolone pulse therapy. Thirty five patients with severe systemic lupus erythematosus (lupus nephritis, severe hemolysis and antiphospholipid syndrome with central nervous system involvement, arterial occlusion and thombocytopenia) were treated by pulse methylprednisolone, followed by long-term corticosteroid (and cyclophosphamide) therapy. Thirty four patients achieved remission, after a mean of 4.7 weeks, which lasted on average for > 2.7 years. Six patients presented with an exacerbation after 1-2.5 years. Twenty eight patients are still in remission. No side effects were observed during pulse therapy. Methylprednisolone bolus therapy is safe and effective in severe systemic lupus erythematosus, including cases of lupus nephritis and severe central nervous system manifestations, but an appropriate choice of long-term therapy is essential.]

[The value of immunoscintigraphy in patients with metastatic malignant melanoma]

PAPÓS Miklós, LÁNG Jenő, CSERNAY László, SZEKERES Lenke, KUBA Attila

[Immunoscintigraphy with 99MTc-labeled F(ab'),fragments of monoclonal antibody (reactive with a high molecular associated antigen) was performed in patients with malignant melanoma. 24 investigations on 23 patients were carried out. A total of 40 lesions in 23 patients were detected by chest radiography, ultrasound, CT, bone scintigraphy or histology. 24 of the 40 lesions (60%) were visualized by immunoscintigraphy. Following correction of the physiological liver background by digital subtraction, 3 liver metastases were localized. These results indicate that immunoscintigraphy with radiolabeled F(ab')2 fragments can provide clinically useful information. ]

[Methodological letter from the Public Health and Epidemiology Technical College on vegetarian and similar diets in crèches and educational establishments]

[The nutritional status of vegetarians is strongly influenced by the type of diet they eat. While semi-vegetarian and lacto-ovo-vegetarian diets can meet the nutrient needs of young children, provided they are carefully and professionally planned, strict vegetarian or macrobiotic diets may not meet the needs for some nutrients and may be deficient in both children and adults. ]

[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.]

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

VOKÓ Zoltán

[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. ]

[Is the implementation of Vojta therapy associated with faster gross motor development in children with cerebral palsy? ]

SANZ-MENGIBAR Jose Manuel , MENENDEZ-PARDIÑAS Monica , SANTONJA-MEDINA Fernando

[Vojta therapy has been reported as clinically beneficial for strength, movement and gross motor activities in individual cases and is being included within the second of three levels of evidence in interventions for cerebral palsy. The goal of this study is to understand the effect of Vojta therapy on the gross motor function. Our clinical trial followed a one group, pre-post design to quantify rates of changes in GMFM-88 after a two-months period undergoing Vojta therapy. A total of 16 patients were recruited. Post-intervention acceleration rates of GMFM-88-items acquisition (0.005; p<0.001) and Locomotor Stages (1.063; p<0.0001) increased significatively following Vojta the­rapy intervention. In this study, Vojta therapy has shown to accelerate the acquisition of GMFM-88-items and Loco­motor Stages in children with cerebral palsy younger than 18 months. Because functional training was not utilised, and other non-Vojta therapy intervention did not influence the outcome, Vojta therapy seems to activate the postural control required to achieve uncompleted GMFM-88-items. ]

[Identifying osteoporosis in a primary care setting with quantitative ultrasound]

HIRDI Henriett Éva, SZOBOTA Lívia

[Osteoporosis is one of the most under-diagnosed and under-treated health conditions. In recent decades, several risk indices have been developed to identify women at risk for low bone mineral density (BMD) who require a BMD test. This study aimed to demonstrate that quantitative ultrasound bone density measurement can indeed be performed simply by nurses working in primary care, which can significantly facilitate early detection of osteopenic and osteoporotic conditions. Method: The medical records of all patients who had an ultrasound of the left heel using the quantitative heel ultrasound machine between March 2021 through December 2021 were reviewed retrospectively. The subjects were 20-64-year-old adults (N=1032). Calcaneal quantitative ultra­sound parameters were registered with Sonost-2000 bone densitometer. The body composition was measured using a multi-frequency segmental body composition analyzer. The measurement results were evaluated with SPSS 22.0 statistical program and descriptive statistics. The mean age of the population studied was 43.12±9.6 years; 29.7% were men and 70.3% were women. Of the women in our study, 2.4% were osteoporotic (T ≤ −2.5), and 49.86% were classified as osteopenic according to the WHO operational definition. Osteopenic values were measured in 32.35% of men. A total of 273 subjects (26.45%) in the study sample were in the 50-64 age group (223 women and 50 men). 4% of women over the age of 50 had osteoporosis and 63.7% had osteopenia. Rating of the OST score no one was placed in the high-risk group. Of the 9 women with osteoporosis, 8 were classified as low-risk and 1 as medium based on OST. Nurses in primary care are able to identify key risk factors for osteoporosis, examine the measurement with quantitative ultrasound, and identify individuals with the disease. ]

A variant of Guillain-Barre syndrome after SARS-CoV-2 vaccination: AMSAN

TUTAR Kaya Nurhan, EYIGÜRBÜZ Tuğba, YILDIRIM Zerrin, KALE Nilufer

Introduction - Coronavirus disease 2019 (COVID-19) is a respiratory infection that has rapidly become a global pandemic and vaccines against SARS-CoV-2 have been developed with great success. In this article, we would like to present a patient who developed Guillain-Barré syndrome (GBS), which is a serious complication after receiving the inactive SARS-CoV-2 vaccine (CoronaVac). Case report – A 76-year-old male patient presented to the emergency department with nine days of progressive limb weakness. Two weeks prior to admission, he received the second dose of CoronaVac vaccine. Motor examination revealed decreased extremity strength with 3/5 in the lower extremities versus 4/5 in the upper extremities. Deep tendon reflexes were absent in all four extremities. Nerve conduction studies showed predominantly reduced amplitude in both motor and sensory nerves, consistent with AMSAN (acute motor and sensory axonal neuropathy). Conclusion - Clinicians should be aware of the neuro­logical complications or other side effects associated with COVID-19 vaccination so that early treatment can be an option.
