[The role of steroid hormones in the protection against oxidative stress]

BÉKÉSI Gábor, FEHÉR János

[The incidence of vascular diseases increases in postmenopausal women. This negative trend seems to be controllable favourably by hormone replacement therapy (HRT). Based on the free radical mediated mechanism of atherogenesis the authors try to find the reasons for these observations on the basis of their and others’ data. They consider the increase of activity and amount of neutrophil enzyme myeloperoxydase by certain steroid particulars one of the most important elements of the vasoprotective effect of HRT. This increase diminishes the production of superoxide anion by the inhibition of the NADPH-oxidase enzyme. The observation proved firstly by the authors, that the plasma levels of myeloperoxydase - and so the ability for the inhibition of superoxide anion production by neutrophils - decreases in elderly people, might explain the higher incidence of some free radical mediated illnesses in the elderly. The authors also give a short review of antioxidant effects of steroids in general.]

[The importance of vitrectomy in the management of diabetic retinopathy in proliferative stage]

BERECZKI Árpád

[Vitrectomy is a closed microsurgical technique, by which intraocular tissue, blood and foreign bodies can be removed through a small incision in the pars plana with an automated suction-cutting device (vitrectom), while maintaining normal or slightly elevated intraocular pressure. This technique requires many accessory instruments (microscope, endoillumination, intraocular instruments, endolaser). The main application of vitrectomy is the treatment of severe complications in diabetes mellitus: diabetic retinopathy in the proliferative stage. Vitrectomy is indicated in diabetic retinopathy for the removal of intraocular bleeding and for the treatment of complications of diabetic proliferative vitreoretinopathy (recurring bleeding, tractional and rhegmatogenous retinal detachment). In the case of intraocular bleeding, early vitrectomy is better than delayed, providing good visus (V: 0,5) in 25% of all patients (based on literature data). In retinal detachment cases of tractional origin, surgery provides satisfactory visus for self-care in 2/3rd of all patients.]

[Gastrointestinal stromal tumor]

GONDA Gábor

[Gastrointestinal stromal tumors were subject of much controversy in the last decades. This type of tumors was delineated from the leiomyoma - leiomyosarcoma group. GISTs show variable histological picture, moreover, they are capable of dual (neurogen and myogen) differentiation as it is proved by immunohistochemical and ultrastructural studies. These tumors have relatively good prognosis, only 10-30% of them is malignant, although it is difficult to predict their behaviour in a given case. The most reliable signs of malignancy - cytological pleoimorphism, high mitotic activity, proliferation index above 10 %, and aneuploid DNA content - are generally accepted. The treatment of choice is excision, but not enucleation. Radical surgery is not necessary, since lymph node metastasis is exceptionally rare. Further investigations revealed electronmicroscopical and immunohistochemical (CD 34, CD 117) similarities of tumor cells and interstitial cells of Cajal (ICC) located in the wall of the bowel. The results of these investigations led to the theory that cells of GIST and ICCs are of the same stem cell origin. Molecular genetic studies are also of great help in the differential diagnosis and in predicting the prognosis of GISTs. Mutations in the c-kit gene can not be detected in leiomyomas, so they are thougt to be specific for GISTs. Mutation of exon 11. of chromosome 4. is observed only in malignant GISTs.]

[Assessing Nurses’ Knowledge of Surgical Wound Care, Complications and Knowledge of Bandages]

FERENCZY Mónika, BÁLINT Beáta, KOMLÓSI Kálmánné, KARÁCSONY Ilona

[Aim of our research was to assess the knowledge of nurses working in surgical departments about surgical wound treatment, phases of wound healing, its complications, and intelligent bandages. Our quantitative, cross-sectional, descriptive examination was carried out in a hospital in Transdanubia with non-random, expert sampling and a self-made questionnaire. Our target group was nurses working in the surgical departments of the hospital (N=85). During the data analysis, the descriptive statistical methods of MS Office Excel 2016 software were calculated: mean, standard deviation, frequency. A χ2-test was used to examine the relationship between variables (p <0.05). Knowledge of bandages was not affected by educational attainment (p>0.05). Those who perform wound care in their daily work have more knowledge about the wound treatment sequence of the wounds that are primarily healing, as well as about intelligent dressings (p<0.1). For the classes, there was a significance for the recognition of complicated wounds, knowledge of the benefit of the absorbable suture and the use of analgesic procedures (p<0.001). In the interests of patient safety, nurses’ knowledge of wound treatment needs to be continuously improved. It is necessary to provide an accessible source of information and further training.]

[History of the development of wound care]

SZABÓNÉ Révész Erzsébet

[The onset of wound care dates back thousands of years. To make the wet wound treatment used today so effective can be a bumpy road. Knowledge of local processes required for wound care, mapping of the effectiveness of materials needed for wound care, treatment of bleeding suppression and traumatic shock caused by injury, destruction of pathogens entering the wound, ensuring optimal hygiene during wound care, treatment of the underlying disease in chronic wounds, all contributed to our ability to provide effective care today. The series of wars over the millennia have greatly aided the development of wound healing, as many developments are still known today that were already used by the army before they spread into everyday practice. ]

[Encephalitis following COVID-19 disease]

VARANNAI Lajos, MAGYAR Zsuzsa, BARANYAI Beatrix, AJZNER Éva, CZURKÓ Marina

[Shortly after that COVID-19 appeared it became clear, that although the disease mainly characterized by respiratory symptoms, other signs frequently appeared, which showed involvation of other organs. There are several new publications which report about neurological complications. According to data developing of encephalitis could be relatively frequent among these. Its symptoms can mostly be observed concommittantly with respiratory symptoms or during critical state of the disease, and several forms were detected. In our patient symptoms of central nervous system involvement appeared a few weeks after healing of COVID-19 pneumonia. Clinical signs, imaging, electroencephalograpy and cerebrospinal fluid analysis confirmed the diagnosis of encephalitis. Considering the previous SARS-CoV-2 infection and the results of the examinations, we think this case was a postinfectious central nervous system disease. There are only a few data available regarding encephalitis after Covid-19 disease in the literature, yet. ]

Cyanocobalamin and cholecalciferol synergistically improve functional and histopathological nerve healing in experimental rat model

ALBAY Cem, ADANIR Oktay, AKKALP Kahraman Asli, DOGAN Burcu Vasfiye, GULAEC Akif Mehmet, BEYTEMUR Ozan

Introduction - Peripheral nerve injury (PNI) is a frequent problem among young adults. Hopefully, regeneration can occur in PNI unlike central nervous system. If nerve cut is complete, gold standard treatment is surgery, but incomplete cuts have been tried to be treated by medicines. The aim of the study was to evaluate and compare clinical and histopathological outcomes of independent treatment of each of Vitamin B12 (B12) and Vitamin D3 (D3) and their combination on sciatic nerve injury in an experimental rat model. Materials and methods - Experimental animal study was performed after the approval of BEH Ethics Committee No. 2015/10. 32 rats were grouped into four (n=8) according to treatment procedures, such as Group 1 (controls with no treatment), Group 2 (intraperitoneal 1 mg/kg/day B12), Group 3 (oral 3500 IU/kg/week D3), Group 4 (intraperitoneal 1 mg/kg/day B12+ oral 3500 IU/kg/week D3). Sciatic Functional Index (SFI) and histopathological analysis were performed. Results - SFIs of Group 2, 3, 4 were statistically significantly higher than controls. Group 2 and 3 were statistically not different, however Group 4 was statistically significantly higher than others according to SFI. Axonal degeneration (AD) in all treatment groups were statistically significantly lower than in Group 1. AD in Group 4 was significantly lower than in Group 2 and 3; there was no significant difference between Group 2 and 3. There was no significant difference between Group 1,2 and 3 in Axonolysis (A). But A of Group 4 was significantly very much lower than all others. Oedema- inflammation (OE-I) in all treatment groups were significantly lower than in Group 1; there was no significant difference between Group 2 and group 4. OE-I in Group 2 and 4 were significantly lower than in Group 3. There were no significant differences between Group 1, 2 and 3 in damage level scores; score of Group 4 was significantly lower than of Group 1. Conclusions - B12 and D3 were found effective with no statistically significant difference. But combined use of B12 and D3 improve nerve healing synergistically. We recommend combined use of B12 and D3 after PNI as soon as possible.

[Therapeutic potential and risks of ayahuasca]

BOKOR Petra, FRECSKA Ede, CSÁNYI Barbara, BRYS Zoltán

[Ayahuasca, which originates from the Amazon Basin, is a psychoactive brew of two components. Its active agents are betacarboline and tryptamine derivatives. Near the spring of the Amazon River this brew is still a central component of many healing and tribal rituals. During the past few decades, the substance has become known among both laymen and scientistss and nowadays its use is spreading all over in Europe. In the present paper we give an overview of the scientific research and describe ayahuasca's main features, the main questions raised over its use, the risk factors and potential benefits. A growing number of scientific results seem to support the psychotherapeutic potential of ayahuasca, which has a strong serotonergic effect, whereas studies on its effect on the immune system also raise the possibility that certain ethno-medical observations can be scientifically proved.]
