[When can we consider cardiopulmonary resuscitation?]

LEN Doyal, DANIEL Wilsher

JULY 27, 1994

Lege Artis Medicinae - 1994;4(07)

[In collaboration with the Royal London Trust, Len Doyal and Daniel Wilsher have developed a set of guidelines for deciding when not to resuscitate a patient. The guidelines describe the procedure to be followed when giving an order not to resuscitate and the clinical, legal and moral criteria that must be met before such a decision can be made. The authors hope that the guidelines will be of assistance to all those responsible for developing criteria for not performing resuscitation in hospitals. ]

[Ultrasonic signs of suspected fetal chromosomal aberration]

ÁDÁM Zsolt, NÉMET János, SZABÓ István, CSABAY László, TÓTH-PÁL Ernő, HAJDÚ Júlia

[The authors summarize the relevant ultrasonic findings in case of suspected fetal chromosomal aberration. Some of these signs are detectable during routine ultrasonic screening examinations. In high-risk cases, prenatal chromosomal analysis is recommended. The following ultrasonic findings indicate a situation of high risk: disturbances of the lymphatic and amniotic fluids (e.g. hydrops, hygroma colli, polyhydramnios, nuchal edema), certain skull and brain alternations, abnormalities of the thorax and abdomen, and „minor” findings such as a single umbilical artery, choroid plexus cyst, pyelectasy, or changes in the size or shape of the long tubular bones, if these signs are accompanied by other anomalies or growth retardation.]

[Advantages and limits of the open tube and flexible esophagoscopes]

TÓTA Julianna, IRÁS Béla

[The two types of endoscopes presently available for examination and treatment of the esophagus are the traditional open tube esophagoscope and the flexible endoscope. Despite the many advantages offered by the flexible endoscope, its limitations should not be forgotten. The open tube esophagoscope should not be thought of as out-of-date, since its new variations have important therapeutic applications. The authors examine the advantages and disadvantages of the two types of esophagoscopes as discussed in the literature. ]

[An update on obstructive sleep apnea]

METES Ágnes, HIRSCHBERG Andor

[Obstructive sleep apnea, which occurs in approximately 2% of the adult population, is the more common of the two major forms of sleep apnea. The conse quences and dangers of excessive daytime sleepiness are emphasized along with the other well-known characteristics of sleep apnea syndrome. Both the decreased upper airway muscle tone during sleep and the negative pressure due to breathing through the obstructed airways may cause upper air ways to collapse. The history has a very important role in the clinical assessment, while the role of the physical examination is limited. An exact and reliable diagnosis may be arrived at through laboratory evaluation, e. g. polysomnography (PSG), Multiple Sleep Latency Test (MSLT), or radiologic examinations. Among conservative treatments, reduction of the body weight is usually effective in mild to moderate cases. In severe apneas, nasal continuous positive airway pressure (nCPAP) is the current treatment of choice. The efficacy of surgical intervention is still controversial. According to most authors, uvulopalatopharyngoplasty (UPPP) has a 50% success rate. Most recently good results have been obtained with maxillo-facial surgery in a variety of selected patients. ]

[The role of echocardiography in the management of ventricular free wall rupture ]

PÁL Mátyás, LENGYEL Mária

[Our goal was to evaluate which diagnostic and therapeutic approaches could provide a better chance of survival. Between January 1, 1987, and December 7, 1992, 772 patients with acute myocardial infarction were treated in the Hungarian Institute of Cardiology. Cardiac rupture was investigated by the retrospective analysis of clinical data, electrome chanical dissociation, echocardiographic signs and autopsy findings. Ventricular free wall rupture was found in 28 cases. The diagnosis was confirmed by autopsy in 23, by intraoperative findings in 4 cases, and by echocardiography and pericardiocentesis in 1 case. Pericardial effusion was detected in 12 of 14 cases undergoing emergency echocardiography. Seven of these had pericardiocentesis and 2 patients underwent surgical pericardial fenestration. Following this 4 patients were referred to surgery. All 4 patients died: 2 during and 2 shortly after operation. The bleeding stopped in 1 case, after pericardiocen tesis and continous drainage and during the 12 month follow-up the patient is alive and well. In acute myocardial infarction, electromechanical dissociation or signs of tamponade are indications for emergency echocardiography, and if pericardial effusion can be visualized, pericardiocentesis should be performed. This can lead to a temporary haemodynamic improvement, providing sufficient time for emergency surgery.]

[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. ]

[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. ]

[Association between cyclothymic affective temperament and hypertension]

NEMCSIK János, BATTA Dóra, KŐRÖSI Beáta, RIHMER Zoltán

[Affective temperaments (cyclothymic, hypertymic, depressive, anxious, irritable) are stable parts of personality and after adolescent only their minor changes are detectable. Their connections with psychopathology is well-described; depressive temperament plays role in major depression, cyclothymic temperament in bipolar II disorder, while hyperthymic temperament in bipolar I disorder. Moreover, scientific data of the last decade suggest, that affective temperaments are also associated with somatic diseases. Cyclothymic temperament is supposed to have the closest connection with hypertension. The prevalence of hypertension is higher parallel with the presence of dominant cyclothymic affective temperament and in this condition the frequency of cardiovascular complications in hypertensive patients was also described to be higher. In chronic hypertensive patients cyclothymic temperament score is positively associated with systolic blood pressure and in women with the earlier development of hypertension. The background of these associations is probably based on the more prevalent presence of common risk factors (smoking, obesity, alcoholism) with more pronounced cyclothymic temperament. The scientific importance of the research of the associations of personality traits including affective temperaments with somatic disorders can help in the identification of higher risk patient subgroups.]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]

VÁLYI Péter

[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]
