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.

Discover the latest journals in Medical and Health Sciences

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  • Editorials are typically not peer reviewed shorter communications from senior members of the Editorial Board or from invited renown scholars.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. Bevezetés: Heveny myocardialis infarctusban a szívizommentés sikere, a beteg életkilátása nagymértékben függ a panasz kezdete és az elzáródott koszorúér rekanalizálása között eltelt ischaemiás időtől. Jelenleg az ér nyitása optimális esetben minden betegnél koszorúér-intervencióval történik. Célkitűzés: Annak vizsgálata, hogy öt év alatt mennyit változtak az ischaemiás idő összetevői, és miben változott az elzáródott ér nyitásának módszere ST-elevációs myocardialis infarctus (STEMI) miatt végzett primer coronariaintervencióban. Módszer: 2014. 01. 01. és 2018. 12. 31. között 1663, STEMI miatt koszorúér-intervencióval kezelt betegnél (1173 férfi és 490 nő) vizsgáltuk évenkénti bontásban a panasztól a koszorúér nyitásáig eltelt idő összetevőit és a 30 napos halálozást. Eredmények: Öt év alatt a panasztól az első egészségügyi kontaktusig medián 2:53 vs. 2:10 óra (p = 0,0132), ettől az intervenciós centrumba történt felvételig medián 1:17 vs. 1:03 óra (p = 0,009), a felvételtől a ballon nyitásáig medián 0:31 vs. 0:29 óra (p = ns) telt el. A panasztól a ballon nyitásáig eltelt idő (medián 5:29 vs. 4:07 óra, p = 0,0001) rövidült, döntően 2014 és 2015 között. A gyógyszerkibocsátó stent beültetése 15%-ról 96%-ra nőtt. A vizsgált években a légzés/keringés támogatás aránya 8,2–10,6–13,9–7,6–8,4, a 30 napos halálozásé 4,1–6,8–11,1–7,4–5,7% volt; a két érték korrelációt mutat (p = 0,827). Következtetés: Öt év alatt a panasztól az első egészségügyi kontaktusig és a kórházi beszállításig eltelt idő rövidült, de az Európai Kardiológiai Társaság ajánlásához képest hosszú; a kórházi felvételtől a ballon nyitásáig eltelt idő megfelelő. A négy órán belüli reperfúzió a betegek közel felében valósult meg. Az intervenciós centrumba való gyorsabb bekerülés javíthatna az eredményen. Orv Hetil. 2021; 162(13): 497–503.

Summary. Introduction: In acute myocardial infarction, the heart muscle salvage, the patient’s life expectancy is highly dependent on the elapsed ischaemic time from the onset of complaint to target vessel recanalisation. Nowadays, target vessel recanalisation is performed with coronary intervention in all patients in optimal case. Objective: To examine how the components of ischemic time and the opening procedure of the occluded coronary have changed over five years in primary intervention done in acute ST-elevation myocardial infarction (STEMI). Method: Authors studied data of 1663 (1173 male and 480 female) STEMI patients in annual breakdowns treated with coronary intervention between 01. 01. 2014 and 31. 12. 2018, time from complaint to coronary artery opening, details of intervention and 30 days mortality rate. Results: During the five years, time intervals were as follows: from onset of complaint to first medical contact: median 2:53 vs. 2:10 hours (p = 0.0132), from this to admission in the interventional centre: median 1:17 vs. 1:03 hours (p = 0.009), from hospital admission to balloon opening: median 0:31 vs. 0:29 hours (p = ns). In total, the complaint to balloon opening time (median 5:29 vs. 4:07 hours, p = 0.0001) diminished, decisively from 2014 to 2015. Ratio of drug-eluting stent implantation increased from 15% to 96%. In the investigated years, the need of respiratory and/or circulatory device support ratio was 8.2–10.6–13.9–7.6–8.4, 30-day mortality rate between 4.1–6.8–11.1–7.4–5.7%; these two values showed a correlation (p = 0.827). Conclusion: The time from complaint to first medical contact and transfer to hospital against the significant decrease is still longer than the recommendation of the European Society of Cardiology. The time from hospital admission to balloon opening is adequate. Reperfusion within four hours was achieved in half of the patients in total. Faster hospitalization may improve results.

Összefoglaló. Bevezetés: A rheumatoid arthritisszel kapcsolatos szolgáltatások igénybevétele nagy teher az egészségügyi rendszerek számára. Célkitűzés: Elemzésünk célja volt a rheumatoid arthritis okozta éves epidemiológiai és egészségbiztosítási betegségteher meghatározása Magyarországon. Adatok és módszerek: Az elemzésben felhasznált adatok a Nemzeti Egészségbiztosítási Alapkezelő (NEAK) finanszírozási adatbázisából származnak, és a 2018. évet fedik le. Meghatároztuk az éves betegszámokat, a prevalenciát 100 000 lakosra, továbbá az éves egészségbiztosítási kiadásokat korcsoportos és nemenkénti bontásban valamennyi egészségbiztosítási ellátás tekintetében. A rheumatoid arthritis kórképet fődiagnózisként a Betegségek Nemzetközi Osztályozása (BNO, 10. revízió) szerinti M0690-es kóddal azonosítottuk. Eredmények: Meghatározó betegforgalmat a gyógyszerek ártámogatása esetében találtunk: 7015 férfi, 23 696 nő, együtt 30 711 fő. A gyógyszer-ártámogatás betegforgalmi adatai alapján a 100 000 főre eső prevalencia férfiaknál 150,2 fő, nőknél 464,0 fő, együtt 314,1 fő volt. A rheumatoid arthritis kezelésére a NEAK 1,64 milliárd Ft-ot (6,07 millió USD, illetve 5,14 millió EUR) költött 2018-ban. A kiadások 19,3%-a férfiaknál, míg 80,7%-a nőknél jelenik meg. A gyógyszer-ártámogatás (az összes kiadás 42,8%-a), a járóbeteg-szakellátás (21,9%) és az aktívfekvőbeteg-szakellátás (12,4%) voltak a meghatározó költségelemek. Az egy betegre jutó átlagos éves egészségbiztosítási kiadás 53 375 Ft (198 USD/167 EUR) volt. Következtetés: A gyógyszerek ártámogatása bizonyult a fő költségtényezőnek. A rheumatoid arthritis előfordulási gyakorisága 3,1-szer magasabb a nők esetében a férfiakhoz képest. Orv Hetil. 2021; 162(Suppl 1): 30–37.

Summary. Introduction: Utilisation of services related to the treatment of rheumatoid arthritis poses a great burden for healthcare systems. Objecive: Our aim was to determine the annual epidemiological disease burden and the health insurance treatment cost of rheumatoid arthritis in Hungary. Data and methods: Data were derived from the financial database of the National Health Insurance Fund Administration (NHIFA) of Hungary, for the year 2018. The data analysed included annual patient numbers and prevalence per 100 000 population and annual health insurance treatment costs calculated for age groups and sex according to all health insurance treatment categories. Patients with rheumatoid arthritis were identified as main diagnosis with the following code of the International Classification of Diseases, 10th revision: M0690. Results: We found a significant patient turnover in pharmaceutical reimbursement: 7015 men, 23 696 women, in total 30 711 patients. Based on patient numbers in pharmaceuticals, prevalence for 100 000 population among men was 150.2 patients, among women 464.0, in total 314.1 patients. In 2018, NHIFA spent 1.64 billion HUF (6.07 million USD, 5.14 million EUR) on the treatment of patients with rheumatoid arthritis. 19.3% of the costs was spent on the treatment of male, 80.7% on female patients. Pharmaceuticals (42.8% of the total expenditures), outpatient care (21.9%) and acute inpatient care (12.4%) were the main cost drivers. Average annual health insurance treatment cost per patient was 53 375 HUF (198 USD/167 EUR). Conclusion: Pharmaceutical reimbursement was the major cost driver. The prevalence of rheumatoid arthritis was by 3.1 higher in women compared to men. Orv Hetil. 2021; 162(Suppl 1): 30–37.

Összefoglaló. Bevezetés: A térd és a lábszár sérülései jelentős terhet jelentenek az egyén és a társadalom számára. Célkitűzés: Elemzésünk célja volt a térd- és lábszársérülés okozta éves epidemiológiai és egészségbiztosítási betegségteher vizsgálata Magyarországon. Adatok és módszerek: Az elemzésben felhasznált adatok a Nemzeti Egészségbiztosítási Alapkezelő (NEAK) finanszírozási adatbázisából származnak, és a 2018. évet fedik le. Vizsgáltuk az éves egészségbiztosítási kiadásokat, azok megoszlását, az éves betegszámot, valamint a 100 000 lakosra vetített prevalenciát korcsoportok és nemek szerinti bontásban. A térd és a lábszár sérülései kórképeket a Betegségek Nemzetközi Osztályozása (BNO, 10. revízió) szerinti S80–S89-es kóddal azonosítottuk. Eredmények: A legköltségesebb ellátási forma az aktívfekvőbeteg-szakellátás volt, amelynek országos betegszáma összesen 18 398 fő (9868 fő férfi, 8530 fő nő) volt. Az aktívfekvőbeteg-szakellátás betegforgalmi adatai alapján a 100 000 főre eső prevalencia a férfiaknál 211,2 fő, a nőknél 167,0 fő, együtt 188,1 fő volt. A NEAK 8,808 milliárd Ft-ot költött 2018-ban a térd- és lábszársérülések kezelésére, ami 32,59 millió USD-nak, illetve 27,62 millió EUR-nak felelt meg. Az aktívfekvőbeteg-szakellátás a teljes egészségbiztosítási kiadás 61,4%-ával volt a legmeghatározóbb költségelem. A kiadások 52,0%-a férfiaknál, míg 48,0%-a nőknél jelent meg. A 49. életévig a férfiak, míg az 50. életév feletti korosztályban a nők sérüléseiből származó ellátások betegszámai és költségei a magasabbak. Következtetés: Az aktívfekvőbeteg-szakellátás bizonyult a fő költségtényezőnek. A betegség előfordulási gyakorisága 26%-kal volt magasabb a férfiak esetében, mint a nőknél. Orv Hetil. 2021; 162(Suppl 1): 54–60.

Summary. Introduction: Injuries to the knee and lower leg pose a great burden for the individual and society. Objective: The aim of our study was to determine the annual epidemiological disease burden and the health insurance treatment cost of knee and lower leg injuries in Hungary. Data and methods: Data were derived from the financial database of the National Health Insurance Fund Administration (NHIFA) of Hungary for the year 2018. The data analysed included annual health insurance costs and their distribution and annual patient numbers and prevalence per 100 000 population calculated for age groups and sex. Patients with knee and lower leg injuries were identified with the following code of the International Classification of Diseases, 10th revision: S80–S89. Results: The most expensive insurance treatment category was acute inpatient care, presenting 18 398 patients in total (9868 men, 8530 women). Based on patient numbers in acute inpatient care, the prevalence in 100 000 population among men was 211.2 patients, among women 167.0 patients, in total 188.1 patients. In 2018, NHIFA spent 8.808 billion HUF on the treatment of patients with knee and lower leg injuries (32.59 million USD, 27.62 million EUR). Acute inpatient care with 61.4% of the total health insurance expenditure was the main cost driver. 52.0% of the costs was spent on the treatment of male, while 48.0% on female patients. Until the age of 49, the number of patients and their costs were higher for men, while those over the age of 50 were higher for women. Conclusion: Acute inpatient care was the major cost driver. The prevalence of the disease was by 26% higher in men compared to women. Orv Hetil. 2021; 162(Suppl 1): 54–60.

Összefoglaló. Bevezetés: Magyarországon a vastag- és a végbéldaganat mindkét nem esetében a harmadik leggyakoribb daganatos megbetegedés és a második leggyakoribb halálok. Célkitűzés: Elemzésünk célja volt a vastag- és végbéldaganat okozta éves epidemiológiai és egészségbiztosítási betegségteher meghatározása Magyarországon. Adatok és módszerek: Az adatok a Nemzeti Egészségbiztosítási Alapkezelő (NEAK) finanszírozási adatbázisából származnak, és a 2018. évet fedik le. A daganat típusait a Betegségek Nemzetközi Osztályozása (BNO, 10. revízió) szerinti C18-as, C19-es, C20-as, C21-es, D010–D014-es és D12-es kóddal azonosítottuk. Meghatároztuk az éves betegszámokat korcsoportos és nemek szerinti bontásban, a prevalenciát 100 000 lakosra, az éves egészségbiztosítási kiadásokat valamennyi ellátási formára és daganattípusra vonatkozóan. Eredmények: A vastag- és végbéldaganatok kezelésére a NEAK 21,7 milliárd Ft-ot (80,2 millió USD; 68,0 millió EUR) költött 2018-ban. A költségek 58,0%-át az aktívfekvőbeteg-szakellátás költségei teszik ki. Az összköltségek megoszlása szerint a legmagasabb költségek a férfiaknál (4,98 milliárd Ft) és a nőknél (3,25 milliárd Ft) is a 65–74 éves korcsoportban figyelhetők meg. A legnagyobb betegszámot a járóbeteg-szakellátás esetében találtuk: 88 134 fő, ezt a háziorvosi ellátás (55 324 fő) és a CT, MRI (28 426 fő) követte. A vastagbél rosszindulatú daganata esetében az egy betegre jutó aktívfekvőbeteg-kassza alapján az éves egészségbiztosítási kiadás 1,206 millió Ft (4463 USD/3782 EUR) volt a férfiak és 1,260 millió Ft (4661 USD/3950 EUR) a nők esetében. Következtetés: Hazánkban az aktívfekvőbeteg-szakellátás bizonyult a fő költségtényezőnek, mely magában foglalja az onkoterápiás gyógyszeres költségeket is. Orv Hetil. 2021; 162(Suppl 1): 14–21.

Summary. Introduction: Colorectal cancer is the third most common type of cancer and the second most common cause of mortality in Hungary in both sexes. Objective: The aim of our study was to determine the annual epidemiological disease burden and health insurance cost of colorectal cancer in Hungary. Data and methods: Data were derived from the financial database of the National Health Insurance Fund Administration (NHIFA) of Hungary for the year 2018. Types of cancer were identified with the following codes of the International Classification of Diseases, 10th revision: C18, C19, C20, C21, D010–D014, D12. The data analysed included annual patient numbers according to age groups and sex, prevalence of care utilisation per 100 000 population, and annual health insurance costs for all types of care and all cancer types. Results: In 2018, NHIFA spent 21.7 billion HUF (80.2 million USD, 68.0 million EUR) on the treatment of colorectal cancer. 58.0% of the costs was spent on acute inpatient care. Regarding total costs, the highest costs were found in the 65–74 age group in both men (4.98 billion HUF) and women (3.25 billion HUF). The highest patient numbers were in outpatient care: 88 134 patients, general practice care (55 324 patients) and CT, MRI (28 426 patients). The annual health care treatment cost per patient was 1.206 million HUF (4463 USD/3782 EUR) in men and 1.260 million HUF (4661 USD/3950 EUR) in women. Conclusion: Acute inpatient care, including the costs of oncotherapeutic pharmaceuticals, was found to be the major cost driver in Hungary. Orv Hetil. 2021; 162(Suppl 1): 14–21.

Abstract

Background

Connexin 43 (Cx43) is the most ubiquitously expressed member of the family of connexins, constituting gap junctions and mediating cell communication, still its role in hearing loss has been little studied.

Methods

Immunohistochemistry was used to detect the expression pattern of Cx43. Spiral ganglia neurons (SGNs) and Corti co-culture were utilized to assay the re-innervation of hair cells by newborn SGNs. Gap19 was utilized to inhibit Cx43 hemichannels. Auditory brainstem responses (ABR) and endocochlear potential (E.P.) were measured to confirm the hearing loss.

Results

The expression of Cx43 in P14 mice was higher than in P0 and P28 (adult) mice, the earlier time point coinciding with the early inner ear development. Additionally, the growth and synapse generation of fibers were inhibited after Gap 19 treatment of the co-cultures of the Corti and SGNs from newborn mice. Furthermore, the inhibition of Cx43 could increase the ABR threshold and decrease E.P. level in postnatal mice, whereas such an effect was not observed in adult mice.

Conclusion

The function of Cx43 is critical during the early development of mouse cochlea but is dispensable in adult mice.

Abstract

Background and aim

There is only a limited number of major publications on the outcome of interventions for isolated popliteal artery stenosis. The purpose of this study was to report our results on mid-term patency and predictors of restenosis.

Patients and methods

This single-center retrospective study included 61 symptomatic patients (males, N = 33; median age, 65.1 years [IQR, 60.7–71.9 years]; Rutherford grade 4–6, N = 14) with at least two patent crural arteries, whose atherosclerotic stenoses/occlusions were treated with percutaneous transluminal angioplasty (PTA) or stenting (using self-expanding bare-metal Astron Pulsar stents) between 2011 and 2018.

Results

Twenty-six patients had PTA, while 35 underwent stenting. The median follow-up was 29 months (IQR, 10–47 months). The primary patency rates were not significantly different (P = 0.629) between PTA and stenting groups. Restenosis developed in nine patients (34.6%) in the PTA group, and in 12 (34.3%) in the stenting group. Restenotic lesions required re-intervention in nine cases (100%) in the PTA group, and in eight (66.7%) in the stenting group. Restenosis developed significantly less frequently (P = 0.010) in patients with a popliteal/P1 stent; the primary patency rates were also significantly better (P = 0.018) in patients with a popliteal/P1 stent when compared to popliteal/P2 plus multi-segment stents. Cox regression analysis identified lesion location as a predictor of in-stent restenosis (HR, 2.5; 95% CI, 1.2–5.5; P = 0.019).

Conclusion

Stenting was not superior when compared to PTA (if selective stenting was not considered as loss of patency). Follow-up should be more thorough in patients undergoing popliteal/P2 or multi-segment stenting.

Abstract

Marfan syndrome is a genetic disorder of the connective tissue, including involvement of the lungs.

Pulmonary function test was performed in 32 asymptomatic adult Marfan patients using European Community for Coal and Steel (ECCS) and Global Lung Function Initiative (GLI) reference values.

Using GLI equations for reference, significantly lower lung function values were noted for forced vital capacity (FVC) (87.0 ± 16.6% vs. 97.1 ± 16.9%; P < 0.01) and forced expiratory volume in the first second (FEV1) (79.6 ± 18.9% vs. 88.0 ± 19.1%; P < 0.01) predicted compared to ECCS. Obstructive ventilatory pattern was present in 25% of the cases when calculating with GLI lower limit of normal (LLN), and it was significantly more common in men as compared to women (n = 6, 50% vs. n = 2, 10%; P = 0.03).

GLI is more suitable to detect early ventilatory changes including airway obstruction in young patients with special anatomic features, and should be used as a standard way of evaluation in asymptomatic Marfan population.

Abstract

Background

Immunosuppressive therapy has improved the outcome of ANCA-associated vasculitis (AAV), but infectious morbidity and mortality remained high. Recognizing its risk factors seems crucial for prevention, aiming to increase survival of these patients.

Methods

We investigated the incidence and types of infections and assessed predictive factors in 132 patients with severe systemic AAV.

Results

Patients with lower than median incidence of total infections/patient-year during induction had lower baseline serum creatinine, dialysis requirement and Charlson comorbidity index (CCI), compared to those with higher than median incidence (P = 0.037; P = 0.024; P = 0.001; respectively). In subgroups with below and above than median number of severe infections/patient-year during induction, differences were found in baseline creatinine (P = 0.002) and dialysis requirement (P = 0.001); comparing the same cohorts during maintenance immunosuppression, baseline dialysis requirement, diabetes, CCI, and dose of cyclophosphamide (CYC) administered as induction therapy differed significantly (P = 0.019; P = 0.015; P = 0.001; P = 0.015, respectively). Severe infections were predicted by baseline serum creatinine (OR 1.002 [CI 1.001–1.003]) and pulmonary manifestation (OR 2.153 [CI 1.017–4.560]) during induction immunosuppression. In multivariable Cox regression model all-cause mortality was independently predicted by severe infection (HR 1.998 [CI 1.214–3.287]). Among the 168 positive cultures Gram-negative bacteria were responsible for blood stream infections in 33%, and respiratory tract infections in 72%.

Conclusions

Advanced renal failure, pulmonary involvement and high degree of comorbidities increase the risk of infection in AAV. Those who suffer infection during induction immunosuppression have worse long-term survival. Our findings indicate the need for high vigilance for infections and close follow-up of comorbidities when treating AAV.

Abstract

During behavioral states of immobility, sleep, and anesthesia, the hippocampus generates high-frequency oscillations called ripples. Ripples occur simultaneously with synchronous neuronal activity in the neocortex, known as slow waves, and contribute to memory consolidation. During these ripples, various neocortical regions exhibit modulations in spike rates and local field activity irrespective of whether they receive direct synaptic inputs from the hippocampus. However, little is known about the subthreshold dynamics of the membrane potentials of neocortical neurons during ripples. We patch-clamped layer 2/3 pyramidal cells in the posterior parietal cortex (PPC), a neocortical region that is involved in allocentric spatial representation of behavioral exploration and sequential series of relevant action potentials during ripples. We simultaneously monitored the membrane potentials of post hoc-identified PPC neurons and the local field potentials of the hippocampus in anesthetized mice. More than 50% of the recorded PPC neurons exhibited significant depolarizations and/or hyperpolarizations during ripples. Histological inspections of the recorded neurons revealed that the ripple-modulated PPC neurons were distributed in the PPC in a spatially non-biased fashion. These results suggest that hippocampal ripples are widely but selectively associated with the subthreshold dynamics of the membrane potentials of PPC neurons even though there is no monosynaptic connectivity between the hippocampus and the PPC.

Abstract

Objectives

Conditions that have similar initial presentations as sepsis may make early recognition of sepsis in an emergency room (ER) difficult. We investigated whether selected physiologic and metabolic parameters can be reliably used in the emergency department to differentiate sepsis from other disease states that mimic it, such as dehydration and stroke.

Methods

Loess regression on retrospective follow-up chart data of patients with sepsis-like symptoms (N = 664) aged 18+ in a large ER in Hungary was used to visualize/identify cutoff points for sepsis risk. A multivariate logistic regression model based on standard triage data was constructed with its corresponding receiver operating characteristic (ROC) curve and compared with another model constructed based on current sepsis guidelines.

Results

Age, bicarbonate, HR, lactate, pH, and body temperature had U, V, W, or reverse U-shaped associations with identifiable inflexion points, but the cutoff values we identified were slightly different from guideline cutoff values. In contrast to the guidelines, no inflexion points could be observed for the association of sepsis with SBP, DPB, MAP, and RR and therefore were treated as continuous variables. Compared to the guidelines-based model, the triage data-driven final model contained additional variables (age, pH, bicarbonate) and did not include lactate. The data-driven model identified about 85% of sepsis cases correctly, while the guidelines-based model identified only about 70% of sepsis cases correctly.

Conclusion

Our findings contribute to the growing body of evidence for the necessity of finding improved tools to identify sepsis at early time points, such as in the ER.
