Among all scientific traditions alive, medical publishing has a good chance to be the oldest. The first fully peer reviewed academic journal, “Medical Essays and Observations” was launched in 1731 by the Royal Society in Edinburgh. Since then, hundreds of medical journals have been published worldwide. Medical publication in Hungary started in 1857 when the famous physician, Markusovszky founded “Orvosi Hetilap”, which has been published since then every week (with short breaks during the world wars). It is now a most prestigious piece in AKJournals’ portfolio, listed in Journal Citation Reports, with a remarkable impact factor.

The primary function of medical articles is the validation of cutting-edge theoretical and clinical research, by providing reference and relevant forums. New drugs and medical practices can only enter the mainstream practise if their randomised trials had passed under the critical lens of prestigious peer reviewed journals. Technical reports help practitioners to improve their arsenal. Case reports confirm theories and provide tools for investigating or disclosing possible malpractice. Review articles serve educational purposes. Some more popular articles may play a role in educating the interested audience.

Types of medical articles

The papers published in medical journals can be classified in the following main categories

  • Research articles report about novel research results, of both theoretical and (direct or indirect) practical relevance.
  • Review articles survey specific topics by summarising and analysing all information available in the medical literature. Reviews are kind of combining results from different studies on the same topic. They can be useful for specialists in the field, may help them to prevent, diagnose, or treat a particular disease.
  • Case reports and case series reports about a concrete story of a concrete patient. They can be interesting because of their uniqueness, not matching any known diagnosis or describing unexpected symptoms. The report should describe each of the diagnosis, treatment, the patient’s response to it and the follow-up history. Case series are related reports about similarly treated patients.
  • Editorials are typically not peer reviewed shorter communications from senior members of the Editorial Board or from invited renown scholars. They discuss questions of relevance for the scientific community at the moment (say, about public health, or more generally, the health system).
  • Letters to the editor are articles of the interactive type, a form for readers to contact the medical journal. They can express comments, questions, or criticisms regarding some articles published in that journal. They provide a sophisticated forum for medical communities.

Összefoglaló. A Cronkhite–Canada-szindróma egy extrém ritka, nem öröklődő, gyomor-bél rendszeri polyposissal, fehérjevesztő enteropathiával és ectodermalis elváltozásokkal járó megbetegedés. A világon eddig összesen körülbelül 500 esetet jegyeztek fel. Az etiológia pontosan nem tisztázott, hátterében elsősorban autoimmun folyamatot feltételeznek. A diagnózis a páciens kórtörténetén, a fizikális vizsgálaton, az endoszkópos képen és a szövettani leleten alapul. A jelen közleményben egy 71 éves férfi beteg esetét mutatjuk be. A klinikai kép és az elvégzett vizsgálatok alapján a tünetek hátterében Cronkhite–Canada-szindrómát igazoltunk, majd a szakirodalomban leggyakrabban alkalmazott kombinált protonpumpagátló, kortikoszteroid és meszalazin adását vezettük be, illetve táplálásterápiát alkalmaztunk. Tudomásunk szerint Cronkhite–Canada-szindrómás beteg esete Magyarországon elsőként kerül ismertetésre. Orv Hetil. 2021; 162(11): 432–438.

Summary. Cronkhite–Canada syndrome is an extremely rare, noninherited disease, characterized by gastrointestinal polyposis, protein-losing enteropathy and ectodermal abnormalities. Approximately 500 cases have been reported worldwide. The aetiology is unknown, most probably autoimmune mechanisms may be involved. The diagnosis is based on patient history, physical examination, endoscopic findings and histology. Here we report the case of a 71-year-old male, diagnosed with Cronkhite–Canada syndrome. The treatment consisted of proton-pump inhibitor, corticosteroids, mesalazin and nutritional therapy. To the best of our knowledge, this is the first report of Cronkhite–Canada syndrome in Hungary.

Összefoglaló. Az extracorporalis membránoxigenizációt egyre gyakrabban alkalmazzák világszerte refrakter légzési és/vagy keringési elégtelenség kezelésében. Intézetünkben 2015-ben kezdtük meg a program előkészítését és felépítését. Célunk az extracorporalis membránoxigenizációs kezelés élettani alapjainak rövid ismertetése, különös tekintettel a venovenosus konfigurációra, és az eddig kezelt eseteink eredményeinek összefoglalása. Az irodalom szisztematikus áttekintése és a kezelt esetek adatainak retrospektív értékelése voltak a módszereink. 2016 óta összesen 14 beteg esetében használtunk extracorporalis membránoxigenizációt (8 férfi, 6 nő, életkor 51 ± 15 év, APACHE II. score 24 ± 7). Az indikáció 9 esetben súlyos refrakter hypoxaemiás légzési elégtelenség, 1 esetben tracheooesophagealis fistula és légzési elégtelenség, 1 esetben műtét alatti támogatás tervezett trachearekonstrukció során és 3 beteg esetében refrakter cardiogen shock volt. Az extracorporalis membránoxigenizáció 11 betegben a légzés, 3 betegben a keringés támogatását szolgálta, 13 venovenosus, 1 venoarteriosus konfigurációban. Az extracorporalis támogatás ideje légzéstámogatás esetében 14 ± 6 nap, a cardialis támogatások esetében 5 ± 4 nap volt. Az intenzív osztályos ápolási idő 27 ± 13, illetve 21 ± 17 nap volt a két betegcsoportban. 9 beteget jó funkcionális állapotban bocsátottunk el, 5 beteg halt meg osztályunkon, további 3 később a kórházi bennfekvés során. Az extracorporalis membránoxigenizációs program regionális centrumokban Magyarországon is megvalósítható. A nemzetközi ajánlások, oktatási módszerek alkalmazásával a nemzetközi irodalomban közölt túlélési eredményekhez hasonló eredmények érhetők el hazánkban is. Orv Hetil. 2021; 162(11): 425–431.

Summary. Extracorporeal membrane oxygenisation is commonly used worldwide for refractory respiratory and circulatory failure. We started to organise the introduction of this therapeutic modality in 2015. Our aim is to give a short review about extracorporeal life support, especially veno-venous extracorporeal membrane oxygenation, and to present our first results. We provide a systematic review of the currently available literature and a summary of our first treatments. As of 2016, we supported 14 patients with extracorporeal membrane oxygenisation (8 men, age 51 ± 15 years, APACHE II score 24 ± 7). The indications were refractory hypoxaemic respiratory failure in 9, tracheo-oesophageal fistula and respiratory failure in 1, support during surgery for planned tracheal reconstruction in 1, and refractory cardiogenic shock in 3 patients. We provided respiratory support in 11, circulatory support in 3 cases, with 13 veno-venous and 1 veno-arterial configuration. The support lasted for 14 ± 6 days in respiratory, and for 5 ± 4 days in cardiac cases. Intensive care length of stay was 27 ± 13 and 21 ± 17 days in the two patient groups. We discharged 9 patients in good functional state, 5 patients died during intensive care and further 3 later, during the hospital stay. Our results show that the implementation of an extracoporeal membrane oxygenation program is feasible in Hungarian tertiary centers. In line with international recommendations and adapting international training courses, the survival is very similar to that reported in the literature. Orv Hetil. 2021; 162(11): 425–431.

Összefoglaló. Számos adat igazolja, hogy az inzulinrezisztencia gyakori jelenség gyermek- és serdülőkorban, és szoros kapcsolatban áll a cardiovascularis kockázat növekedésével, ami miatt a kérdéskörre az életnek ebben a korai szakaszában is kiemelt figyelmet kell fordítani. Ma már egyre több ismerettel rendelkezünk a kockázati tényezőket illetően, nincs azonban egységes álláspont az inzulinrezisztencia meghatározására vonatkozóan a klinikai gyakorlatban, és nem rendelkezünk megfelelő laboratóriumi markerekkel, melyek segítségével a veszélyeztetetteket széles körben eredményesen lehetne azonosítani. Mindezek alapján a laboratóriumi módszerrel történő szűrés ebben az életkorban nem indokolt, azonban a társuló és következményes kórállapotok klinikai alapon történő felismerésére törekedni kell. A cardiovascularis kockázat megelőzésére irányuló életmódbeli prevenció hatásos az inzulinrezisztencia csökkentésében, a gyakorlatban azonban kivitelezése és eredményessége korlátozott. A gyógyszeres intervenció jelenleg ebben az életkorban csak egyes szelektált esetekben kerülhet alkalmazásra. További klinikai kutatásokra van szükség az inzulinrezisztencia mérése, az életmódbeli és gyógyszeres intervenciós lehetőségek területén annak érdekében, hogy sikeres stratégiák legyenek kialakíthatók a cardiovascularis halálozás megelőzése, csökkentése érdekében. Orv Hetil. 2021; 162(11): 403–412.

Summary. Numerous data confirm that insulin resistance is a common phenomenon in children, and closely links to an increase in cardiovascular risk, therefore it is urgent to pay attention to this from early childhood. Today, we have more and more knowledge about risk factors, but there is no common position on the definition of insulin resistance in clinical practice and we do not have adequate laboratory markers to identify those at risk effectively. Based on all these factors, laboratory screening is not justified at this age, however, efforts should be made to recognize associated and consequent conditions on a clinical basis. Lifestyle prevention to prevent cardiovascular risk is effective in reducing insulin resistance, but in practice its implementation and effectiveness are limited. At present, pharmacological intervention can only be used in certain selected cases with this age group. Further clinical research is needed to measure insulin resistance, lifestyle and drug intervention options in order to develop successful strategies to prevent and reduce cardiovascular death.

Összefoglaló. Bevezetés: A kiégés jelensége fokozottan érinti az egészségügyi dolgozókat, a nagyfokú stressz, a folyamatos fizikai és emocionális megterhelés miatt. A kiégés mérését fogorvosok körében végeztük, mivel Magyarországon még nem készült csak fogorvosokat mérő keresztmetszeti vizsgálat. Célkitűzés: Elsődleges célunk a fogorvosi kiégés előfordulásának, súlyosságának mérése, a rizikófaktorok kiszűrése volt. Másodlagos célul a kiégés veszélyére való figyelem felkeltését tűztük ki az érintett csoportban. Módszer: Az adatgyűjtés a ’Maslach Burnout Inventory – Human Services Survey’ 22 tételes magyar, validált változatával történt online formában. Eredmények: Online kérdőívünket 407 fogorvos töltötte ki. A következő eredményeket kaptuk: az emocionális kimerülés esetében a válaszadók 20%-a (81 fő) tartozik a magas kategóriába, a cinizmus dimenziójának esetében a válaszadók 17,5%-át (70 fő) jellemzi a magas pontszám. A teljesítményvesztés magas dimenziója a minta 75%-ában (302 fő) volt igazolható. Szignifikáns (p≤0,05) védőfaktornak találtuk a harmonikus kollegiális viszonyt, a hobbi meglétét, a 2–4 óra napi munkát, a támogató otthoni és munkahelyi légkört, az egészségi probléma és a saját vállalkozás hiányát. Szignifikáns negatív eltérést 6–10 éve dolgozó férfiak körében találtunk. Következtetés: Az eredmények felhívják a figyelmet a legfontosabb protektív tényezőkre, melyek segítségével csökkenthető a kiégés mértéke. Orv Hetil. 2021; 162(11): 419–424.

Summary. Introduction: Burnout has an increased impact on healthcare workers due to severe stress, constant physical and emotional strain. Burnout was measured among dentists, as no such cross-sectional study has been made in Hungary. Objective: Our primary goal was to measure the incidence and severity of dental burnout and to screen for the risk factors. Our secondary goal was to raise awareness of the risk of burnout in the affected group. Method: Data collection was performed online with the 22-item Hungarian validated version of Maslach Burnout Inventory – Human Services Survey. Results: 407 dentists completed our online questionnaire. The following results were obtained: in the case of emotional exhaustion, 20% of the respondents belong to the high category, in the cynicism dimension, 17.5% of the respondents have high scores. The high dimension of performance loss is typical in 75% of the sample. We found that harmonious collegial relationships, the existence of a hobby, 2–4 hours of daily work, a supportive home and work atmosphere, the lack of health problems and self-employment are significant (p≤0.05) protective factors. Significant negative differences were found among men who had been working for 6–10 years. Conclusion: The results draw attention to the most important protective factors that can help reduce the rate of burnout. Orv Hetil. 2021; 162(11): 419–424.

Abstract

Heat stress affects the performance of poultry species and also induces immunosuppression. Chickens can be treated by thermal conditioning to have better heat stress tolerance. Our purpose was to determine the effect of acute heat stress on the immune response, i.e. antibody production against Newcastle disease virus (NDV) and change in the proportion of leukocyte components, in chicks subjected to prenatal heat conditioning. Eighty as-hatched broiler chicks from the same parent stock were used: control (40 chicks incubated at 36.7 °C from days 18–20 of embryonic life) and thermally manipulated (TM) (40 chicks incubated at 38.4 °C from day 18–20 of embryonic life; 4 h/day). The chickens were exposed to heat stress: at day 19 (31 °C/8 h) and at day 35 (32 °C/10 h). The first heat stress (day 19) decreased the lymphocyte counts and significantly increased the heterophil counts (P < 0.05) in both treatments (from 34.25 to 55% in the controls and from 37 to 60.06% in the TM chicks). The second heat stress (day 35) did not alter the heterophil and lymphocyte profiles of the chickens. Before the heat stress, all of the chickens (control and TM) presented the same positive antibody titres to NDV vaccination. After the first heat stress, 50% of the control samples and 40% of samples from the TM chickens were negative. After the second heat stress, 80% of the TM samples were negative.

Abstract

A case of a 13-year-old girl after being injured on the left eyeball by a stick from a cage, is presented. Along vitreous haemorrhage, retinal oedema and ischaemia, the disc was replaced by a cavity. Multimodal imaging was performed, which confirmed the optic nerve damage. The eye had no light perception anymore. Our case is a demonstration for complete avulsion of the optic nerve after blunt injury.

Abstract

In recent years, coronary computed tomography angiography (CCTA) has emerged as an accurate and safe non-invasive imaging modality in terms of detecting and excluding coronary artery disease (CAD). In the latest European Society of Cardiology Guidelines CCTA received Class I recommendation for the evaluation of patients with stable chest pain with low to intermediate clinical likelihood of CAD. Despite its high negative predictive value, the diagnostic performance of CCTA is limited by the relatively low specificity, especially in patients with heavily calcified lesions. The discrepancy between the degree of stenosis and ischemia is well established based on both invasive and non-invasive tests. The rapid evolution of computational flow dynamics has allowed the simulation of CCTA derived fractional flow reserve (FFR-CT), which improves specificity by combining anatomic and functional information regarding coronary atherosclerosis. FFR-CT has been extensively validated against invasively measured FFR as the reference standard. Due to recent technological advancements FFR-CT values can also be calculated locally, without offsite processing. Wall shear stress (WSS) and axial plaque stress (APS) are additional key hemodynamic elements of atherosclerotic plaque characteristics, which can also be measured using CCTA images. Current evidence suggests that WSS and APS are important hemodynamic features of adverse coronary plaques. CCTA based hemodynamic calculations could therefore improve prognostication and the management of patients with stable CAD.

Abstract

Klippel-Trenaunay syndrome (KTS) is an uncommon congenital condition, resulting in vascular malformations affecting capillary, venous, and lymphatic systems and bone and/or soft tissue hypertrophy. Magnetic Resonance Angiography (MRA) may be useful in assessing the severity of the disease and for treatment planning. We present two cases of two white men with the typical clinical presentation of Klippel-Trenaunay syndrome i.e. vascular malformations (capillary, venous and lymphatic) and localized bone and/or soft tissues hypertrophy. Splenic hemangiomas were evidenced in both patients and MRA was helpful in assessing and delineating the abnormal venous drainage system. KTS is a complex disorder whose true prevalence and etiology are still unknown. In most cases the emblematic clinical manifestation consisting in vascular malformations and extremity overgrowth is represented. KTS may be associated with several different conditions including scoliosis and splenic hemangiomas. The presence of the lateral marginal vein (LMV) is pathognomonic. Imaging is fundamental in confirming the diagnosis and for therapeutic strategies. An effective treatment does not exist to date and a multidisciplinary approach is usually required to prevent complications.

Abstract

Combined anatomical and functional evaluation of coronary artery disease (CAD) using computed tomography (CT) has recently emerged as an accurate, robust, and non-invasive tool for the evaluation of ischemic heart disease. Cardiac CT has become a one-stop-shop imaging modality that allows the simultaneous depiction, characterization, and quantification of coronary atherosclerosis and the assessment of myocardial ischemia. Advancements in scanner technology (improvements in spatial and temporal resolution, dual-energy imaging, wide detector panels) and the implementation of iterative reconstruction algorithms enables the detection of myocardial ischemia in both qualitative and quantitative fashion using low-dose scanning protocols. The addition of CT perfusion (CTP) to standard coronary CT angiography is a reliable tool to improve diagnostic accuracy. CTP using static first-pass imaging enables qualitative assessment of the myocardial tissue, whereas dynamic perfusion imaging can also provide quantitative information on myocardial blood flow. Myocardial tissue assessment by CTP holds the potential to refine risk in stable chest pain or microvascular dysfunction. CTP can aid the detection of residual ischemia after coronary intervention. Comprehensive evaluation of CAD using CTP might therefore improve the selection of patients for aggressive secondary prevention therapy or coronary revascularization with high diagnostic certainty. In addition, prognostic information provided by perfusion CT imaging could improve patient outcomes by quantifying the ischemic burden of the left ventricle. The current review focuses on the clinical value of myocardial perfusion imaging by CT, current status of CTP imaging and the use of myocardial CTP in various patient populations for the diagnosis of ischemic heart disease.
