[Making way for pseudoscience?]


OCTOBER 27, 1993

Lege Artis Medicinae - 1993;3(10)

[In June 1993, the Royal British Medical Association decided that the subjects of paramedical medicine (naturopathy) would no longer be treated with disparaging disapproval, but would be taught in medical schools. This decision came as a surprise to most doctors, although chiropractic (osteopathy), herbal therapy (herbal medicine) and acupuncture have held their position in medicine for quite some time. ]

[The origin of serum catalase in healthy subjects and in some diseases]

GÓTH László

[The activity of serum catalase is highly increased in acute pancreatitis, hemolytic disorders and in some liver diseases, but there is no data on its tissue origin. The serum catalase activity was determined by a spectrophotometric assay in healthy subjects (n = 4275) as well as in increased erythropoesis (n = 424), in hemolytic diseases (hemolytic anemia = 12, megaloblastic anemia = 28, Zieve syndrome = 8, hemorrhage = 38), in acute pancreatitis, (n = 111), in liver diseases (fatty liver = 21, alcoholic hepatitis = 42, acute yellow atrophy = 18, toxic hepatitis = 15), and in liver congestion due to cardiac circulatory failure (n = 28). These diseases yielded increased serum catalase activity. This enzyme has no tissue specific isoenzymes, therefore mathematical and statistical approaches were used. The correlation between serum hemoglobin and serum catalase was analysed. The catalase release was estimated from the time activity curves of serum catalase and compared to its tissue equivalent. In healthy subjects about 60 percent of serum catalase derived from the erythrocytes and the rest from other tissues. During enhanced erythropoesis and in hemolytic diseases, similarly to hemoglobin, its source was the erythrocyte pool. In acute pancreatitis also the erythrocytes might be responsible for the increased serum catalase level. in some liver diseases as well as in liver congestion due to cardiac circulatory failure the increase of serum catalase derived from the liver cells. The diagnostic analysis of serum catalase requires the consideration of its increase as well as its origin. ]

[The surgical treatment of shoulder instability]


[The author briefly reviews the static and dynamic stabilizing system and the biomechanics of the shoulder and describes his principles and techniques of the surgical treatment of instability. A modified Bankart procedure is used for recurrent anterior dislocation. Bone blocks are implanted in cases of locked posterior dislocation. Different forms of cranial instability are described as well as partial and total superior glenoidal lesions. The author discusses surgical procedures used in the treatment of these instabilities. Cranial instability leads to impingement syndrome, which results in rotator cuff lesions. These lesions increase instability and the increased impingement leads to further rotator cuff damage. This vicious cycle can be interrupted by surgical intervention.]

[Clinical application of specific antibodies in immunotherapy of transplantation]


[In organ and tissue transplantation practice as well as in the therapy of autoimmune, haematological, immunological and oncological diseases, the possibility for applying immunotherapy is occuring more frequently. The paper deals with all those reagents which are primarily of polyclonal or monoclonal immunglobuline origin and play a significant role in the various cell-bound immune reactions on the surface of lymphocytes. In addition to the anti-lymphocyte or/rather anti-thymocyte globuline as well as the Orthoclone (anti-CD3 monoclonal antibody) reagents well known in clinical practice, it also refers to other lymphocyte surface anti-marker monoclonal anti-bodies (anti CD4, -CD8; anti TCR, anti-LFA reagents) under clinical trial. The article reviews the possible uses of the group of immunotherapeutical reagents in the clinical practice of Kidney and bone marrow transplantation. The pharmacological mechanism, side effects, and prospects for a wider use of these reagents in the future are discussed.]

[Prenatal follow up of a complex cardiac malformation complicated with complete AV block]

SZABÓ István, CSABAY László, NÉMET János, HAJDÚ Júlia, PAPP Zoltán

[In a congenital disorder of heart development where the complex cardiac malformation is pared with complete atrioventricular block heart rate is stabile between 50–60 beats/min. Transfer of atrial impulses through the AV node is fully blocked and the slow rhythmic heart beat is maintained by a ventricular pacemaker. In a case of such a complete cardiac malformation recognized in week 32 of gestation and the AV block complication caused stabile 57–58 beat/min bradycardia. 2-di mensional, pulsed and color Doppler ultrasonography was used to identify the disorder and to follow up the intrauterine condition of the fetus. Cardiotocography (CTG) could not generate appreciable results at such a low heart rate. During observation no centralization of fetal circulation causing intrauterine hypoxia was recorded. Updated knowledge on the pathogenesis and obs tetrical management of the fetal third degree AV block is also presented. In this case ultrasonography allowed clear-cut identification of the disorder and also ensured correct evaluation of the intrauterine status of the fetus when other diagnostic methods for evaluation were not applicable. ]

[Eurpean Concerted Action on Thrombosis and Disabilities Angioma Pectoris Study]


[Patients with more than 50% stenosis in one or more coronary arteries had significantly higher fibrinogen levels (p<0.0001). Reduced fibrinolytic activity was also observed in patients with coronary artery stenosis, mainly due to higher levels of plasminogen activator inhibitor-1 (PAI). Decreased fibrinolytic activity was strongly associated with diabetes, elevated triglyceride levels, smoking and impaired left ventricular systolic pump function. Cholesterol levels correlated mainly with protein C and plasminogen levels.]

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.

[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. ]

[Functional magnetic resonance imaging studies in pain research]

ÉDES Andrea Edit, JUHÁSZ Gabriella

[Functional imaging studies opened a new way to understand the neural activity underlying pain perception and the pathomechanism of chronic pain syndromes. In the last twenty years several results of functional magnetic resonance imaging (fMRI) studies have been published about examining the different aspects of complex pain experience. The aim of these studies is to understand the functioning of the pain control system, the so-called pain matrix, activated by acute nociceptive stimulus. Another important field of pain research is the investigation of neuronal processes underlying chronic pain, since the pathomechanism of this is still unclear. Our review aims to provide insight into the methods of pain research using fMRI and the achievements of the last few years.]

[Can we influence the negative drug attitude? Interpretation of the rejection of COVID-19 vaccine in the light of results of a pilot study ]

POGÁNY László , HORVÁTH A. András, LAZÁRY Judit

[Vaccination refusal is a serious obstacle to minimizing the spread of COVID-19. Nevertheless, the rejection of vaccine can be considered the result of a negative attitude towards medical treatment, and according to our previously published data, it can be influenced by the underlying affective state. Increased incidence of affective disorders and anxiety could be observed globally during the pandemic, which may have a significant impact on vaccination acceptance. The aim of our pilot study was to determine the association between clinical improvement of affective and neurocognitive symptoms and change of drug attitude and health control beliefs in a sample of psychiatric patients. A data set of 85 patients with psychiatric disorder has been analysed with the use of Patient’s Health Belief Questionnaire on Psychiatric Treatment (PHBQPT) with 5 subscales (Negative Aspect of Medication – NA; Positive Aspect of Medication – PA; Doctor health locus of control- Doctor HLOC; Internal HLOC; Psychological Reactance – PR); Hospital Anxiety Depression Scale (HADS-Anx; HADS-Dep) and neurocognitive tests, such as the Stroop test and the Trail Making Tests. All the tests were performed before and after a 14 days treatment. Paired t-tests and generalized linear models were performed to assess the associations between the variables. The baseline scores of NA and HADS-Anx correlated significantly (p=0.001) and after two weeks of treatment NA decreased (p=0.001), while Doctor HLOC and Internal HLOC increased (p=0.001 and p=0.006). The patients performance of the neurocognitive tests improved (all p<0.05). The reduction of HADS-Anx (p=0.002) and HADS-Dep (p=0.006) scores showed significant associations with the decrease of NA. Increase of the PA score was associated with reduction of HADS-Dep (p=0.028). Improvement of neurocognitive functions had no effect on PHBQPT scores. Important conclusions can be drawn regarding the rejection of the COVID-19 vaccine based on the associations found between the intensity of affective and anxiety symptoms and the attitude towards treatment. Our findings suggest that affective symptoms have a negative influence on the attitude towards treatment and that the improvement of these symptoms can facilitate the acceptance of the therapy, regardless of diagnosis. The modest effect of the improvement of neurocognitive functioning on the attitude towards drugs and the significant role of affective-emotional factors suggest that the accep­tance of vaccination probably cannot be facilitated solely with the aid of educational programs. Considering the increasing incidence of affective disorders during the COVID-19 pandemic, the screening of affective and anxiety symptoms and treatment of these disorders could be an important step towards the acceptance of the vaccine. Although psychiatry is not considered as a frontline care unit of the COVID cases, more attention is needed to pay on the availability of mental health services because refuse of vaccine can develop due to affective disorders too.]
