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  • Editorials are typically not peer reviewed shorter communications from senior members of the Editorial Board or from invited renown scholars.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

Abstract

In this study, the ability of microRNA-1906 (miR-1906) to attenuate bone loss in osteoporosis was evaluated by measuring the effects of a miR-1906 mimic and inhibitor on the cellular toxicity and cell viability of MC3T3‐E1 cells. Bone marrow-derived macrophage (BMM) cells were isolated from female mice, and tartrate-resistant acid phosphatase signalling was performed in miR-1906 mimic-treated, receptor-activated nuclear factor kappa-B (NF-κB) ligand (RANKL)-induced osteoclasts. In-vivo, osteoporosis was induced by ovariectomy (OVX). Rats were treated with 500 nmol/kg of the miR-1906 mimic via intrathecal administration for 10 consecutive days following surgery. The effect of the miR-1906 mimic on bone mineral density (BMD) in OVX rats was observed in the whole body, lumbar vertebrae and femur. Levels of biochemical parameters and cytokines in the serum of miR-1906 mimic-treated OVX rats were analysed. The mRNA expression of toll-like receptor 4 (TLR4), myeloid differentiation primary response 88 (MyD88), p-38 and NF-κB in tibias of osteoporotic rats (induced by ovariectomy) was observed using quantitative reverse-transcription polymerase chain reaction. Treatment with the miR-1906 mimic reduced cellular toxicity and enhanced the cell viability of MC3T3‐E1 cells. Furthermore, osteoclastogenesis in miR-1906 mimic-treated, RANKL-induced osteoclast cells was reduced, whereas the BMD in the miR-1906 mimic-treated group was higher than in the OVX group of rats. Treatment with the miR-1906 mimic also increased levels of biochemical parameters and cytokines in the serum of ovariectomised rats. Finally, mRNA expression levels of TLR4, MyD88, p-38 and NF-κB were lower in the tibias of miR-1906 mimic-treated rats than in those of OVX rats. In conclusion, the miR-1906 mimic reduces bone loss in rats with ovariectomy-induced osteoporosis by regulating the TLR4/MyD88/NF‐κB pathway.

Abstract

Objective

The present report evaluates the protective effects of luteolin against diabetic retinopathy (DR).

Materials and methods

Diabetes was induced in rats by i.p. administration of 60 mg/kg of streptozotocin (STZ), followed by treatment with luteolin for 4 weeks. The effects of luteolin were determined based on the blood glucose and cytokine levels, and parameters of oxidative stress in retinal tissue of DR rats. The diameter of retinal vessels was estimated by fundus photography. A Western blot assay was used to determine the expression of apoptotic proteins and Nod-like receptor 3 (NLRP3) pathway proteins in the retina of DR rats. A molecular docking study was performed to evaluate the interaction between luteolin and NLRP3.

Results

The level of blood glucose was reduced in the luteolin-treated group compared with the DR group. Reductions in cytokines and oxidative stress were observed in the retinal tissues of the luteolin-treated group relative to the DR group. Moreover, treatment with luteolin reduced the expression of NLRP1, NOX4, TXNIP, and NLRP3 proteins, and ameliorated the altered expression of apoptotic proteins in the retina of DR rats.

Conclusion

In conclusion, luteolin prevents retinal apoptosis in DR rats by regulating the NLRP/NOX4 signalling pathway.

Abstract

Feline calicivirus (FCV), feline alphaherpesvirus 1 (FHV-1) and feline panleukopenia virus (FPLV) as well as retroviral agents such as feline leukaemia virus (FeLV) and feline immunodeficiency virus (FIV) are important viral pathogens of cats. The aim of this study was to detect and characterise FHV-1, FPLV, FeLV, FIV and feline foamy virus (FFV) in oropharyngeal, nasal and conjunctival swabs from 93 cats that had been screened for FCV previously. We wanted to determine the possible risk factors for infection with these viruses. The prevalence was found to be 12.9% for FHV-1 and 9.7% for FPLV. FIV was detected only in two samples and FeLV in one sample, whereas the presence of FFV was not demonstrated in any of the clinical samples. The statistical analysis of the results showed that breed, age, health status, and lifestyle are important predisposing factors to FHV-1 (P < 0.05). For FPLV, only clinically unhealthy animals were found to be at risk (P < 0.001). Sequence analysis revealed that the two FIV-positive samples in this study contained different (A and B) subtypes of the virus. This is the first report on the occurrence of subtype A FIV in Turkey.

A kórházi visszavételt igénylő súlyos folyadék-elektrolit zavar mint az ileosztóma egyik szövődménye

Readmission indicated by severe fluid-electrolyte disturbances as a complication of ileostomy

Magyar Sebészet
Authors: Kornél Vajda, Ildikó Horti, Kornélia Trepák, and László Sikorszki

Összefoglaló. Bevezetés: A neoadjuváns radio-kemoterápia után végzett rektum tumorok műtéte során általános gyakorlattá kezd válni a tehermentesítő ileosztóma képzése a súlyos varratelégtelenségekből származó szövődmények csökkentése érdekében. Maga az ileosztóma is 20–60%-os előfordulási gyakorisággal lehet szövődmények forrása, 16,9–40%-ban pedig a dehidráció képezi a visszavétel okát. Célkitűzés: Vizsgálatunk célja az volt, hogy áttekintsük saját beteganyagunkat az ileosztóma szövődményei alapján, különös tekintettel a dehidrációra és az abból fakadó következményekre, ennek segítségével pedig kidolgozzunk egy kezelési protokollt, amely a betegek segítségére van ezen súlyos szövődmények megelőzésében. Eredmények: Retrospektív módon elemeztük az osztályunkon 2017. 09. 01. és 2019. 12. 31. között különböző indikáció alapján készített tehermentesítő kacs ileosztóma képzésben részesült betegek morbiditási és mortalitási adatait. Ezen idő alatt 252 rektoszigmoideális reszekciót és 33 abdominoperineális rektum exstirpációt végeztünk. Ileosztómát 110 betegnél készítettünk. 27 beteg (24,5%) került visszavételre súlyos vesefunkció-romlás és ioneltérések miatt. 24 beteg egy alkalommal, 1 beteg két alkalommal, 2 beteg pedig három alkalommal került visszavételre. A visszavétel a műtéttől számítva átlagosan 49,6 nappal (1–343) történt. A felvételkor és visszavételkor a betegek átlagos GFR értéke 54,66 (38–60) ml/perc/1,73 m2 – 22,8 (5–51) ml/perc/1,73 m2 (p = 0,001), átlagos se Na 140,7 (133–145) mmol/l – 131,4 (111–144) mmol/l (p = 0,001), se K 4,6 (3,2–5,6) mmol/l – 5,37 mmol/l (3,6–7,6) (p = 0,0005) és az se Kreatinin 89,6 (54–149) µmol/l – 333,3 (107–877) (p = 0,001) µmol/l volt. Megbeszélés: Tekintettel az ileosztóma okozta dehidráció rövid és hosszú távú súlyos szövődményeire, valamint a magas visszavételi kockázatra, fontos a betegek kockázatbecslése, a korai oktatás és a dehidráció megelőzése, a rendszeres kontroll biztosítása. Amennyiben a feltételek adottak, az ileosztóma korai zárása is megfontolandó.

Summary. Introduction: After the operations of rectal tumours following neoadjuvant chemo-radio therapy it is a common practice to create a defunctioning ileostomy in order to prevent complications due to anastomotic leak. The ileostomy itself can be the source of complications with 20–60% incidence rate, while dehydration causes 16.9–40% of readmissions. Aims: Our goal was to review our own cases on the basis of complications of ileostomy particularly with regard to dehydration and its consequences. We wanted to develop a therapeutic protocol to help prevent these severe complications. Results: We retrospectively analyzed the morbidity data of our patients who had defunctioning ileostomy for different indications between 01.09.2017–31.12.2019. During this period, 252 rectosigmoid resections and 33 abdominoperineal resections of the rectum were performed. Ileostomy was created for 110 patients. 27 patients (24.5%) were readmitted with severe renal impairment and electrolyte disturbances. 24 patients were readmitted once, 1 patient twice and 2 patients 3 times. Readmission happened an average of 49.6 days (1–343) after the operation. At admission and readmission the average of GFR (glomerular filtration rate) of patients was 54.66 (38–60) ml/min/1.73 m2 – 22.8 (5–51) ml/min/1.73 m2 (p = 0.001), the average of serum Na level was 140.7 (133–145) mmol/l – 131.4 (111–144) mmol/l (p = 0.001), the average of serum K level was 4.6 (3.2–5.6) mmol/l – 5.37 (3.6–7.6) mmol/l (p = 0.005) and the average of serum creatinine level was 89.6 (54–149) µmol/l – 33.3 (107–877) µmol/l (p = 0.001). Conclusion: With regard to the short and long term severe complications of dehydration and the high risk of readmission caused by ileostomy, it is important to estimate the risk of patients, to educate the inpatients as early as possible, to commence the prevention of dehydration, and regularly monitor in the outpatient setting. Provided the conditions are given, the early closure of ileostomy should be considered.

Abstract

Objective

Multiple sclerosis (MS) is a chronic and progressive neurological disease affecting the central nervous system (CNS). Some studies report an association between MS pathogenesis and cytokines. Here, we aimed to determine and evaluate serum kisspeptin-10 level in MS patients and its related clinic parameters.

Materials and Methods

A total of 92 participants, 46 patients with relapsing-remitting MS (mean age, 38.92 ± 14.76; 22 men and 24 women) and 46 healthy controls (mean age, 37.04 ± 15.49; 22 men and 24 women) were enrolled in the study. All MS patients were neurologically examined, and magnetic resonance imaging (MRI) was performed. Clinical data (neuropathic pain, expanded disability status scale (EDSS) score, etc.) and the patients' demographic characteristics were recorded. The serum level of kisspeptin-10 was analyzed by enzyme-linked immunosorbent assay (ELISA) method.

Results

The level of kisspeptin-10 was measured as 2.305 ± 2.781 ng/mL in MS patients and 9.342 ± 9.483 ng/mL in controls. MS patients had significantly lower kisspeptin-10 levels than controls (P = 0.000). Kisspeptin-10 has the highest diagnostic value [Area under curve (AUC) = 0.881, 95% confidence interval (CI), 0.812–0.950] as cut-off value (2.470), sensitivity (80.40%) and specificity (72.87%) in the MS group. Furthermore, the kisspeptin-10 level was negatively correlated with third ventricle diameter (TVD) (P = 0.048) and vitamin D concentration (P = 0.004). No significant difference was determined between kisspeptin-10 and other clinical parameters.

Conclusion

As a potential prognostic biomarker, serum kisspeptin-10 level was significantly lower in patients with MS than in those without. Moreover, we observed negative correlations between vitamin D, TVD size, and kisspeptin-10. We think comprehensive studies are needed to verify and elucidate this issue.

Authors: István Rozsos, Gergely Vadász, and Melinda Gadácsi

Összefoglaló. Célkitűzés: A már több mint egy évtizede alkalmazott lézeres aranyérműtét technikai tapasztalatai alapján kidolgozott mikrohullámú termo-koagulációs műtét bevezetésének korai eredményeinek bemutatása. Közleményünkben a lézeres és microwave elven működő eszközökkel végzett aranyérműtéti eredményeinket mutatjuk be. Betegek és módszerek: A 26 lézerszállal és a 14 mikrohullámú merev antennával végzett műtét összehasonlítását végeztük el. Eredmények: Mindkét csoportban az átlagos panaszmentesség 2 hét alatt alakult ki, a két módszer között jelentős különbséget nem találtunk. Megbeszélés: Az új műtéti eljárásokat kereső világunkban az általunk most kipróbált lehetőség lehetővé teszi a gyors és teljes gyógyulást adó kezelést. A termo elven működő rendszerek kevesebb fizikai roncsolással érik el a kívánt hatást. A microwave technika a lézeres beavatkozások biztonsági előírásainak szükségessége és körülményessége nélkül alkalmazható.

Summary. Abstract: In addition to the traditional surgical options for hemorrhoid disease, newer treatment methods are evolving along the principle of reducing the burden on patients and providing similar or better healing. Thermo-based systems achieve the desired effect with less physical destruction. In this paper, we discuss the results of hemorrhoid surgery performed with laser and microwave devices. Patients and methods: We compare the results of 26 operations done with laser fibers and 14 operations using microwave rigid antennas. Results: In both groups, the average complaint-free period developed within 2 weeks, no significant difference was found between the two methods. Discussion: As we are always looking for new methods and surgical solutions, an option we are testing now indicates that thermal treatment can provide a quick and complete cure without the need for complicated safety requirements of laser interventions.

Vissza a jövőbe: gastro-oesophagealis junctio subepitheliális tumorának laparoszkópos transgastricus resectiója

Back to the future: laparoscopic transgastric resection of a subepithelial tumor in the gastroesophageal junction

Magyar Sebészet
Authors: Zsolt Varga, Péter Sárkány, and Dezső Tóth

Összefoglaló. Esetismertetés: A gyomor subepitheliális tumorainak laparoszkópos ékresectiója egy széleskörűen elfogadott és alkalmazott eljárás. A gastro-oesophagealis junctio (GOJ) közeli elváltozások esetén ez a technika azonban a gyomorbemenet szűkületének magas kockázata miatt erősen korlátozott. Ilyen lokalizáció esetén megfelelő technika lehet a laparoszkópos transgastricus resectio. Esetünkben egy 44 éves férfi dysphagiájának hátterében azonosított subepitheliális tumor resectióját végeztük el ilyen módon. A műtét során a pneumoperitoneum készítését követően a gyomrot orogastricus szonda segítségével insuffláltuk, majd 3 darab ballonnal rendelkező portot vezettünk a gyomorba. A 6 × 3 × 3 cm-es elváltozás intragastricus kimetszését követően a nyálkahártyát tovafutó öltéssorral zártuk. A speciment zsákba helyeztük, majd a gyomorból és a hasüregből eltávolítottuk. A portok gastrotomiás nyílásait zártuk. 24 órán át nasogastricus szondát hagytunk hátra, hasűri draint nem hagytunk vissza. A pneumoperitoneum idő 115 perc volt, vérveszteséget vagy intraoperatív szövődményt nem észleltünk. Eseménytelen posztoperatív szak után a beteget a műtétet követő harmadik napon otthonába bocsátottuk. A szövettani vizsgálat leiomyomát igazolt. Megbeszélés: Bár a páciens utánkövetése még folyamatban van, az irodalmi adatok alapán GOJ közeli elváltozások esetén a transgastricus technika biztonságos, hatékony, valamint jó funkcionális eredményt biztosító eljárás, a kiújulás magasabb kockázata nélkül.

Summary. Case report: Laparoscopic wedge resection of the subepithelial tumors of the stomach is a widely accepted and utilized approach. The use of this technique for lesions located near the gastroesophageal junction (GEJ) is rather limited by the high risk of consequential stenosis of the gastric inlet. The laparoscopic transgastric resection can be a feasible choice for this location. A 44-year-old male patient had been investigated for dysphagia, which confirmed a subepithelial gastric lesion. We performed the resection of the tumor using this technique. After the creation of pneumoperitoneum, the stomach was insufflated using an orogastric tube, then 3 balloon-type ports were inserted intragastrically. The 6×3×3 cm large tumor was resected and the mucosa was closed by running sutures. The specimen was placed into a plastic bag, then retrieved from the stomach and the abdominal cavity. The gastrotomy sites of the ports on the stomach were closed. A nasogastric tube was left in situ for 24-hours without any intraabdominal drains. The pneumoperitoneum time was 115 minutes long, blood loss or intraoperative complication was not noticed. The postoperative period was uneventful, and the patient was discharged from the hospital three days after surgery. The histological examination confirmed the diagnosis of leiomyoma. Summary: Even though the follow-up of the patient is ongoing, according to the scientific literature, transgastric resection of subepithelial tumors located near the GEJ is a safe and effective technique, which provides good functional results, without having a higher risk for recurrence.
