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  • Editorials are typically not peer reviewed shorter communications from senior members of the Editorial Board or from invited renown scholars.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.

Hematológia–Transzfuziológia
Authors: László Szerafin, Péter Takács, Gabriella Varjasi, László Rejtő, Péter Ilonczai, Lóránt Varju, Katalin Keresztes, and János Jakó

Összefoglaló. Bevezetés: A krónikus lymphoid leukémia kezelésében jelentős előrelépést eredményezett az ibrutinibterápia bevezetése. A gyógyszer első vonalbeli és többed vonalbeli kezelése is magas remissziós arányt eredményezett, bár a terápia korai bevezetése és a kedvező genetikai eltérések esetén az eredmények jobbak. A progressziómentes túlélést befolyásoló egyéb tényezőkről azonban még kevés adat áll rendelkezésre. Célkitűzés: Krónikus lymphoid leukémiás betegek ibrutinibkezelése során a teljes hematológiai remisszió elérését és a progressziómentes túlélés időtartamát befolyásoló tényezők vizsgálata. Betegek és módszer: 47 krónikus lymphoid leukémiás beteg (életkor: 39–84 év, férfi 27, nő 20, követési idő 5–58 hónap, medián 15 hónap) klinikai és laboratóriumi adatainak retrospektív elemzése. Eredmények: A teljes hematológiai remisszió elérése független volt a betegek nemétől, életkorától, a betegség stádiumától, az immunglobulin gén nehézlánc-variábilis régió státuszától, a genetikai aberrációktól, az abszolút neutrophilszámtól, az abszolút monocytaszámtól és a vörösvértestnagyság-eloszlási görbe szélességétől. A progressziómentes túlélést a komplett remisszió elérése (p = 0,00073) és a magasabb abszolút neutrophilszám (<4 G/l vs. ≥4 G/l, p = 0,022) befolyásolta szignifikánsan, a vörösvértestnagyság-eloszlási görbe szélességértékével való összefüggés pedig statisztikailag határértéken volt (p = 0,065). A Cox-féle regressziós elemzésbe bevont változók közül csak a teljes hematológiai remisszió elérése mutatott szignifikáns hatást a progressziómentes túlélésre (p = 0,0147). Következtetések: A teljes hematológiai remisszió elérése az egyéb vizsgált tényezőktől független, szignifikáns hatással bír a betegek progressziómentes túlélésére. Az abszolút neutrophilszám és a vörösvértestnagyság-eloszlási görbe szélessége szintén hasznos kiegészítő prognosztikus marker lehet. Az elemzett esetek száma még alacsony a komolyabb következtetések levonására, azonban így is elmondható, hogy az eredmények egy része már a szakirodalom korábbi eredményeit tükrözi.

Summary. Introduction: The introduction of ibrutinib therapy has led to significant advances in the treatment of chronic lymphocytic leukemia. Both first-line and multiple-lines treatments of the drug resulted in high remission rates, although results were better with early initiation of therapy and favorable genetic abnormalities. However, little data are available on other factors influencing progression-free survival. Objective: To investigate factors influencing the achievement of complete hematological remission and progression-free survival with ibrutinib treatment in patients with chronic lymphocytic leukemia. Patients and metods: Retrospective analysis of clinical and laboratory data from 47 chronic lymphoid leukemia patients (age: 39–84 years, male 27, female 20, follow-up 5–58 months, median 15 months). Results: Achieving complete hematologic remission was independent of patient gender, age, disease stage, immunoglobulin heavy chain variable region status, genetic aberrations, absolute neutrophil count, absolute monocyte count, and red blood cell distribution width. Progression-free survival was significantly affected by complete remission (p = 0.00073), and higher absolute neutrophil counts (<4 G/l vs. ≥ 4 G/l, p = 0.022), the red blood cell distribution width was statistically less significant (p = 0.065). Of the variables included in the Cox regression analysis, only the achievement of complete hematologic remission had a significant effect on progression-free survival (p = 0.0147). Conclusions: Achieving complete hematologic remission, independent of the other factors studied, has a significant effect on patients’ progression-free survival. Absolute neutrophil count and red blood cell distribution width can also be a useful additional prognostic marker. The number of analyzed cases is still low to draw more serious conclusions, but it can still be said that some of the results already reflect previous results in the literature.

Abstract

This study was to investigate whether high-intensity interval training (HIIT) and saffron aqueous extract (SAE) would provide a synergistic effect to improve tumor volume reduction and also modulate pro- and anti-apoptotic protein expression in tumor tissue of 4T1 breast cancer-bearing mice. Female mice following induction of breast cancer through injection of 4T1 cell lines were randomly divided into four groups: (1) HIIT, (2) SAE, (3) HIIT+ SAE, and (4) control. The tumor volume was significantly lower in the HIIT, SAE, and HIIT+SAE groups than in the controls. The protein level of caspase-3 in the HIIT and the SAE groups was higher than in the control and the HIIT+SAE groups. The Bax protein level in the SAE group was higher than in the control. The HIIT+SAE group showed a lower level of Bax than the HIIT and the SAE groups. The protein level of Bcl-2 was higher in the HIIT+SAE vs. both the HIIT and the SAE groups. Finally, the ratio of Bax/Bcl-2 was significantly higher in the HIIT and the SAE groups than in the HIIT+SAE and control groups. These findings indicate that a combination of HIIT and SAE interventions does not improve the apoptotic induction in tumor tissue, while both HIIT and SAE treatments may mediate apoptotic pathway as evinced by the elevated ratio of Bax/Bcl-2 and caspase-3 levels during tumor progression in breast cancer-bearing mice.

Összefoglaló. A humán szervezetnek az alapvető biokémiai reakcióihoz vasra és annak biztonságos használatára van szükség. Emberben vasexcretios út hiányában a vasanyagcsere sarkalatos pontja a duodenális absorptio, amelyet a májsejtek által termelt hormon, a hepcidin szabályoz. A hepcidin a ferroportin lisosomalis degradációját okozva blokkolja a vasnak a vérbe való belépését a duodenális enterocytából, a reticuloendothelialis rendszer (RES) macrophagokból és a májsejtekből. A reguláló hormon képzését a szervezet vaskészlete mellett az erythropoiesis, hypoxia és inflammatorikus folyamatok befolyásolják. A szabályozás kóros eltérései vashiány vagy vasterhelés útján súlyos betegségeket okozhatnak. A hepcidin képződését befolyásoló folyamatokat illetően ismereteink jelentősen gyarapodtak, közleményünk célja ezek bemutatása.

Summary. The basic biochemical reactions of the human body require iron and its safe utilisation. In absence of an iron-excreation pathway in human, the pivotal point of iron metabolism is duodenal absorption, which is regulated by a hormone produced by liver cells, the hepcidin. Causing lisosomal degradation of ferroportin, hepcidin blocks the iron entry into the blood from duodenal enterocytes, reticuloendothelial system (RES) macrophages, and liver cells. In addition to the body’s iron stores, the production of the regulatory hormone is also affected by erythropoiesis, hypoxia and inflammatory processes. Abnormal regulation can lead to serious illness through iron deficiency or iron stress. Regarding the processes influencing the formation of hepcidin, our knowledge has significantly increased and the aim of our paper is to present them.

Összefoglaló. Bár az elmúlt évtizedben számos új gyógyszer került be a myeloma multiplex kezelésének eszköztárába, a betegség az esetek nagy részében továbbra is gyógyíthatatlan, ezért új hatóanyagok bevonására van szükség. A venetoclax a bcl-2 antiapoptotikus fehérje gátlása révén ható új típusú gyógyszermolekula, amelynek különböző hematológiai malignitásokban történő alkalmazásáról az elmúlt években számos tanulmány készült. Myeloma multiplexben való alkalmazása a hatásmechanizmusnak megfelelően a magas bcl-2/mcl-1, illetve bcl-2/bcl-xl aránnyal rendelkező betegeknél előnyös, amely kedvező konstelláció elsősorban a t(11;14) transzlokált betegeknél áll fenn. Bár korai tanulmányok mutattak kedvező eredményeket más citogenetikai eltéréssel rendelkező betegeknél is, a törzskönyvezési igénnyel indított nagy, randomizált 3. fázisú Bellini klinikai vizsgálat a venetoclaxszal kezelt betegeknél ugyan a t(11;14) csoportban nagyon kedvező eredményekre vezetett, de a nem t(11;14) betegeknél többlethalálozást és OS-csökkenést mutatott ki. A vizsgálati eredmények értelmében a venetoclax-alapú terápia myeloma multiplexben csak t(11;14) betegeknek ajánlható. Az optimális alkalmazással és kombinációs partnerekkel kapcsolatban további vizsgálatok szükségesek, mindazonáltal a venetoclax terápia a myeloma multiplex személyre szabott kezelésének irányába tett első lépést jelentheti.

Summary. Although recent decades introduced several new drugs to multiple myeloma therapy, the disease is still considered incurable in most cases and thus warrants the development of new agents. Venetoclax is a novel type of drug inhibiting the antiapoptotic bcl-2 molecule whose use in varying hematological malignancies has been evaluated by a multitude of studies in recent years. Considering its mechanism of action, application in multiple myeloma is possible in patients with high bcl-2/mcl-1 and bcl-2/bcl-xl ratios. This favourable constellation is primarily found in patients with t(11;14) translocations. Although early studies showed some promising results in patients with different citogenetic makeup, the large randomized phase 3 Bellini study which confirmed ventetoclax’s high effectivity in t(11;14) patients, proved increased mortality and OS loss in the case of non-t(11;14) patients treated with the drug. In light of these results, venetoclax based therapy may only be recommended for t(11;14) myeloma patients. Further research is needed to determine optimal application and combination partners, but venetoclax therapy may be the first step towards personalized myeloma care.

Background:

It has been observed that gluteal-femoral adipose tissue has a protective effect against risk factors for cardiovascular disease but has not yet been concluded how different evaluation methods of fat distribution affect the results.

Methods:

To test the hypothesis that B-mode ultrasound-measured subcutaneous adipose tissue distribution is associated with cardiovascular risk factors, 326 Japanese unmedicated postmenopausal women aged 50-70 years were analyzed. Subcutaneous adipose tissue thickness at 6 sites (anterior and posterior aspects of trunk, upper-arm, and thigh) and serum total (TC) and high-density lipoprotein cholesterol (HDLC) was measured, and a ratio of HDLC to TC (HDLC/TC) was calculated. We used Bayesian linear regression with 4 separate models with each model predicting HDLC/TC.

Results:

Our first model provided evidence for an inverse correlation (r = –0.23) between ultrasound measured body fat (6 site measurement) and HDLC/TC. The second model noted evidence for an inverse correlation between trunk fat and HDLC/TC and found evidence for the null with respect to the correlation between thigh fat and HDLC/TC. Therefore, we added thigh fat to the null model to produce Distribution Model 2. Within this model, we noted an inverse correlation (r = –0.353) between trunk fat and HDLC/TC. Our last model determined that within the trunk fatness, the abdominal area (anterior trunk) was a larger predictor than the subscapular site (posterior trunk).

Conclusion:

These results support the evidence that ultrasound-measured abdominal subcutaneous adipose tissue thickness is a non-invasive predictor for monitoring the risk for dyslipidemia in postmenopausal women.

Abstract

The present case report describes the clinical signs and case resolution of an intact 9-year-old male crossbreed dog with spontaneous constipation. The dog presented with abdominal pain, lack of appetite, tenesmus and without signs of defecation in the last 4 days. No important alterations were observed in the complete blood count and biochemistry. A substantial obstruction caused by a faecaloma and a prostate with increased size was observed on X-rays. Benign prostatic hyperplasia (BPH) was confirmed by ultrasonography (size: 48.29 cm3) and by testing the serum canine prostate-specific arginine esterase concentration (105.97 ng/mL). Colon impaction was resolved with rectal enemas within two days. BPH was treated with osaterone acetate. Ultrasonographic checks were performed after 60 and 180 days from the demission and a concrete constant reduction of prostatic volume and of the clinical signs was established. Faecaloma is an uncommon finding in male dogs, and it occurs especially as a consequence of BPH. Colon impaction in patients with BPH is usually subclinical, but it is important to underline how, in severe cases, perforation of the colon and faecal peritonitis can occur, leading to fatal conditions for the animal. In conclusion, prostatic enlargement should always be considered in male dogs suffering from colonic impaction.

Összefoglaló. Az új típusú koronavírus-fertőzés (COVID–19) nagy terhet ró az egészségügyi ellátórendszerre és a társadalomra. A betegségnek három nagy szakasza van, melyek alapvetően meghatározzák a kezelést. Az I–IIA fázisban az antivirális, míg a IIB–III. fázisban a gyulladásgátló kezelés áll előtérben, melyhez intenzív terápiás, szupportív kezelés csatlakozik. A jelen ajánlás kizárólag a gyógyszeres kezelésre vonatkozik, és a rendelkezésre álló bizonyítékok alapján foglalja össze a terápiás lehetőségeket. Emellett egy javasolt kezelési algoritmust is tartalmaz. Orv Hetil. 2021; 162(17): 643–651.

Summary. The novel coronavirus infection (COVID-19) places a heavy burden on the health care system and our society. There are three major stages in the disease that fundamentally determine treatment approaches. Phases I–IIA require primarily antiviral treatment. In phases IIB–III, anti-inflammatory treatment is needed accompanied by intensive and supportive care. This recommendation applies only to pharmacotherapy and summarizes the therapeutic options based on the available evidence. It also includes a proposed treatment algorithm. Orv Hetil. 2021; 162(17): 643–651.

Összefoglaló. Az achondroplasia kialakulásáért az FGFR3-gén mutációja tehető felelőssé, mely a porc növekedési lemezében található chondrocyták érésében okoz zavart. Az esetbemutatásban szereplő lánygyermeknél a születést követő első hónapban a klinikai, laboratóriumi és röntgenvizsgálatok alapján achondroplasia igazolódott. A klinikai tünetek közé tartoznak a rövid végtagok – különösen a proximalis szegmensben –, a macrocephalia, a hypotonia és a horkolás. Szembetűnő a középarc hypoplasiája. A középfül diszfunkciója tovább súlyosbítja a kórképet, sok esetben megfigyelhető a hallás nagyfokú csökkenése, illetve kezelés hiányában akár a hallás elvesztése. A közlemény részletesen bemutatja az obstruktív alvási apnoe szindróma diagnózisrendszerét és kezelési alternatíváit, hangsúlyozva az orthodontiai szempontokat. A fül-orr-gégészeti és a fogszabályozó terápiának köszönhetően, a diagnózistól számított harmadik évre, az alvási apnoe szindróma megszüntetésével a folyamatos pozitív nyomású lélegeztetést el lehetett hagyni. A horkolás és az alvási apnoe szindróma kezelése napjainkban egyre nagyobb hangsúlyt kap, melynek komplex kezelésében a fogszabályozás is jelentős lehet. A harmonikus együttműködés és teamkezelés betegünknél jelentős életminőség-javulást eredményezett. Orv Hetil. 2021; 162(17): 683–688.

Summary. Development of achondroplasia is due to the mutation of FGFR3 gene, which disrupts the maturation of chondrocytes found in the growth plate. The diagnosis of the girl in the present case study was established based on clinical symptoms, laboratory tests and X-ray imaging in the first month following childbirth. Clinical symptoms include shorter limbs especially in the proximal segments, macrocephaly, hypotonia and snoring. Hypoplasia of the midface is apparent. Dysfunction of the middle ear further worsens the condition, in many cases severe hearing loss and, without treatment, even deafness can be observed. The publication describes the diagnostic criteria and therapeutic options of obstructive sleep apnea syndrome in detail, with an emphasis on the orthodontic aspects. A comprehensive combined three-year oto-laryngological and orthodontic treatment finally succeeded in controlling the sleep apnea syndrome and it was possible to discontinue the continuous positive airway pressure therapy by the end of the orthodontic therapy. Nowadays, even more alternative therapeutic approaches are available to treat snoring and sleep apnea syndromes, in which the role of orthodontics must not be neglected. Harmonic collaboration and team work treatment resulted in a significant improvement in the quality of life of our patient. Orv Hetil. 2021; 162(17): 683–688.

Abstract

Prion disease is a fatal neurodegenerative disease with a broad host range in humans and animals. It is caused by proteinase K-resistant prion protein (PrPres). In previous studies, a heterogeneous infection in Cervidae and Caprinae was reported. Chronic wasting disease (CWD) has been frequently reported as the only prion disease in Korea that occurs in livestock. Thus, there is a possibility of transmission of CWD to Korean native black goats. However, PrPres has not been investigated thus far in Korean native black goats. We found strong linkage disequilibrium between c.126G>A and c.414T>C (r2 = 1) and between c.718C>T and c.126G>A (r2 = 0.638). In addition, the haplotype GTGTAAAC (representing codons 42, 102, 127, 138, 143, 146, 218 and 240) showed the highest frequency with 45.1%. Among 41 Korean native black goats, 20 animals (48.78%) were homozygous for the susceptible haplotypes (histidine at codon 143, asparagine at codon 146 and arginine at codon 154). Interestingly, we did not detect PrPres bands in any of the tested animals, including the 20 animals carrying potential scrapie susceptible haplotypes.
