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


[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]


[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]


[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.]

[The Comprehensive Aphasia Test in Hungarian]


[In this paper we present the Comprehensive Aphasia Test-Hungarian (CAT-H; Zakariás and Lukács, in preparation), an assessment tool newly adapted to Hungarian, currently under standardisation. The test is suitable for the assessment of an acquired language disorder, post-stroke aphasia. The aims of this paper are to present 1) the main characteristics of the test, its areas of application, and the process of the Hungarian adaptation and standardisation, 2) the first results from a sample of Hungarian people with aphasia and healthy controls. Ninety-nine people with aphasia, mostly with unilateral, left hemisphere stroke, and 19 neurologically intact control participants were administered the CAT-H. In addition, we developed a questionnaire assessing demographic and clinical information. The CAT-H consists of two parts, a Cognitive Screening Test and a Language Test. People with aphasia performed significantly worse than the control group in all language and almost all cognitive subtests of the CAT-H. Consistent with our expectations, the control group performed close to ceiling in all subtests, whereas people with aphasia exhibited great individual variability both in the language and the cognitive subtests. In addition, we found that age, time post-onset, and type of stroke were associated with cognitive and linguistic abilities measured by the CAT-H. Our results and our experiences clearly show that the CAT-H provides a comprehensive profile of a person’s impaired and intact language abilities and can be used to monitor language recovery as well as to screen for basic cognitive deficits in aphasia. We hope that the CAT-H will be a unique resource for rehabilitation professionals and aphasia researchers in aphasia assessment and diagnostics in Hungary. ]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]


[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

[Focus on Lege Artis Medicinae (LAM)]

VASAS Lívia, GEGES József

[Three decades ago, LAM was launched with the goal of providing scientific information about medicine and its frontiers. From the very beginning, LAM has also concerned a special subject area while connecting medicine with the world of art. In the palette of medical articles, it remained a special feature to this day. The analysis of the history of LAM to date was performed using internationally accepted publication guidelines and scientific databases as a pledge of objectivity. We examined the practice of LAM if it meets the main criteria, the professional expectations of our days, when publishing contents of the traditional printed edition and its electronic version. We explored the visibility of articles in the largest bibliographic and scientific metric databases, and reviewed the LAM's place among the Hun­ga­rian professional journals. Our results show that in recent years LAM has gained international reputation des­pite publishing in Hungarian spoken by a few people. This is due to articles with foreign co-authors as well as references to LAM in articles written exclusively by foreign researchers. The journal is of course full readable in the Hungarian bibliographic databases, and its popularity is among the leading ones. The great virtue of the journal is the wide spectrum of the authors' affiliation, with which they cover almost completely the Hungarian health care institutional sys­tem. The special feature of its columns is enhanced by the publication of writings on art, which may increase Hungarian and foreign interest like that of medical articles.]

We aimed to analyze the clinical, laboratory and neuroimaging findings in patients with sporadic Creutzfeldt-Jakob disease (CJD) in a single center as well as to review other published cases in Turkey. Between January 1st, 2014 and June 31st, 2017, all CJD cases were evaluated based on clinical findings, differential diagnosis, the previous misdiagnosis, electroencephalography (EEG), cerebrospinal fluid and cranial magnetic resonance imaging (MRI) findings in our center. All published cases in Turkey between 2005-2018 were also reviewed. In a total of 13 patients, progressive cognitive decline was the most common presenting symptom. Two patients had a diagnosis of Heidenhain variant, 1 patient had a diagnosis of Oppenheimer-Brownell variant. Seven patients (53.3%) had been misdiagnosed with depression, vascular dementia, normal pressure hydrocephalus or encephalitis. Eleven patients (87%) had typical MRI findings but only 5 of these were present at baseline. Asymmetrical high signal abnormalities on MRI were observed in 4 patients. Five patients (45.4%) had periodic spike wave complexes on EEG, all appeared during the follow-up. There were 74 published cases in Turkey bet­ween 2005 and 2018, with various clinical presentations. CJD has a variety of clinical features in our patient series as well as in cases reported in Turkey. Although progressive cognitive decline is the most common presenting symptom, unusual manifestations in early stages of the disease might cause misdiagnosis. Variant forms should be kept in mind in patients with isolated visual or cerebellar symptoms. MRI and EEG should be repeated during follow-up period if the clinical suspicion still exists.
