GAJDÁN Nikolett, LÉGRÁDY Péter, BAJCSI Dóra, MORVAY Zita, NAGY Endre, LETOHA Annamária, KYPROS Constantinou, FEJES Imola, SONKODI Sándor, ÁBRAHÁM György

[Renovascular hypertension is a well-known form of secunder hypertension. Two thirds of cases are caused by atherosclerotic plaque and one third are caused by fibromuscular dysplasia. The prevalence of it is less than 1%. Digital subtraction angiography is considered the goldstandard diagnostic method. The 58-year old female patient was hospitalized with resistant hypertension. Duplex ultrasonography showed fibromuscular stenosis the in left renal artery. Percutaneous transluminal angioplasty and stenting were performed. Her blood pressure normalized. The patient did not attend the control examinations. Next time in 2001, she was referred to our emergency department with increased blood pressure of 210/140 mmHg. Following control ultrasonography angiography showed total occlusion of the left renal artery and significant stenosis of the right renal artery. Left nephrectomy was necessary due to shrunken kidney and dilatation and stenting of the right renal artery. The blood pressure normalized again. Since 2004 until 2014 despite of the regular visits, we detected in stent restenosis of the right renal artery almost in each year. Even so, renal function was preserved all the time. In autumn of 2014, the patient suffered severe stroke, and few months later at the age of 74 she died. There are many open questions to discus concerning the right treatment of renovascular hypertension yet. Even so by performing 12 intravascular interventions we could ensure her acceptable quality of life for 16 years.]

[Systemic ANCA-associated vasculitis. Induction immunosuppression therapy, complications and outcome. Part 2]

HARIS Ágnes, POLNER Kálmán

[The present review is compiled of two parts, the first part aims to summarize the induction immunosuppressive therapy, the second part delineates the outcome and complications of ANCA-associated vasculitis. ANCA-associated vasculitis is a systemic disease, accompanied with rapidly progressive glomerulonephritis and severe, often life-threatening extrarenal complications. By early diagnosis and immediate initiation of immunosuppressive therapy both patient and renal outcome have been substantially improved. The major aims of modern therapeutic protocols are, besides improving survival, to decrease immunosuppressive drug toxicity and avoid infections. Immunosuppression is based on the combination of large dose of corticosteroid and cyclophosphamide, which is advisable to supplement by plasma exchange. The B-cell depleting anti-CD20 monoclonal antibody rituximab, which has already been available in Hungary, has been proved to be similarly effective in newly diagnosed ANCA-vasculitis, and even more effective in a relapsing disease, compared to cyclophosphamide. Amongst rituximab’s further indications in this disease is the preservation of young women’s fertility, and it also has priority in some other special cases. Early diagnosis and prompt immunosuppressive treatment have resulted that ANCAvasculitis became a treatable disease with reasonably good clinical outcome, yet both the disease and the immunosuppressive medications frequently cause complications, which necessitate continuous alertness of the attending nephrologists.]

[Isolated systolic hypertension in the elderly and very elderly]

FARSANG Csaba

[In the elderly (˃65 yrs) and very elderly (˃80 yrs) large clinical investigations showed that isolated systolic hypertension is the most frequent form of hypertension. In the background, several cardiovascular, neural and hormonal changes have been proved. One of the most important pathogenetic factor is the increase of arterial stiffness. This leads to the increase of pulse wave velocity and systolic blood pressure, and also to the decrease of diastolic blood pressure. Consequently, pulse pressure increases. All these factors contribute to the increase in incidence and prevalence of cardiovascular consequences of hypertension, which are more frequent than in younger ages.]

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

[The connection between the socioeconomic status and stroke in Budapest]

VASTAGH Ildikó, SZŐCS Ildikó, OBERFRANK Ferenc, AJTAY András, BERECZKI Dániel

[The well-known gap bet­ween stroke mortality of Eastern and Western Euro­pean countries may reflect the effect of socioeconomic diffe­rences. Such a gap may be present between neighborhoods of different wealth within one city. We set forth to compare age distribution, incidence, case fatality, mortality, and risk factor profile of stroke patients of the poorest (District 8) and wealthiest (District 12) districts of Budapest. We synthesize the results of our former comparative epidemiological investigations focusing on the association of socioeconomic background and features of stroke in two districts of the capital city of Hungary. The “Budapest District 8–12 project” pointed out the younger age of stroke patients of the poorer district, and established that the prevalence of smoking, alcohol-consumption, and untreated hypertension is also higher in District 8. The “Six Years in Two Districts” project involving 4779 patients with a 10-year follow-up revealed higher incidence, case fatality and mortality of stroke in the less wealthy district. The younger patients of the poorer region show higher risk-factor prevalence, die younger and their fatality grows faster during long-term follow-up. The higher prevalence of risk factors and the higher fatality of the younger age groups in the socioeconomically deprived district reflect the higher vulnerability of the population in District 8. The missing link between poverty and stroke outcome seems to be lifestyle risk-factors and lack of adherence to primary preventive efforts. Public health campaigns on stroke prevention should focus on the young generation of socioeconomi­cally deprived neighborhoods. ]

[The Comprehensive Aphasia Test in Hungarian]

ZAKARIÁS Lilla, RÓZSA Sándor, LUKÁCS Ágnes

[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. ]

Comparison of direct costs of percutaneous full-endoscopic interlaminar lumbar discectomy and microdiscectomy: Results from Turkey

ÜNSAL Ünlü Ülkün, ŞENTÜRK Salim

Microdiscectomy (MD) is a stan­dard technique for the surgical treatment of lumbar disc herniation (LDH). Uniportal percutaneous full-endoscopic in­terlaminar lumbar discectomy (PELD) is another surgical op­tion that has become popular owing to reports of shorter hos­pitalization and earlier functional recovery. There are very few articles analyzing the total costs of these two techniques. The purpose of this study was to compare total hospital costs among microdiscectomy (MD) and uniportal percutaneous full-endoscopic interlaminar lumbar discectomy (PELD). Forty patients aged between 22-70 years who underwent PELD or MD with different anesthesia techniques were divided into four groups: (i) PELD-local anesthesia (PELD-Local) (n=10), (ii) PELD-general anesthesia (PELD-General) (n=10), (iii) MD-spinal anesthesia (MD-Spinal) (n=10), (iv) MD-general anesthesia (MD-General) (n=10). Health care costs were defined as the sum of direct costs. Data were then analyzed based on anesthetic modality to produce a direct cost evaluation. Direct costs were compared statistically between MD and PELD groups. The sum of total costs was $1,249.50 in the PELD-Local group, $1,741.50 in the PELD-General group, $2,015.60 in the MD-Spinal group, and $2,348.70 in the MD-General group. The sum of total costs was higher in the MD-Spinal and MD-General groups than in the PELD-Local and PELD-General groups. The costs of surgical operation, surgical equipment, anesthesia (anesthetist’s costs), hospital stay, anesthetic drugs and materials, laboratory wor­kup, nur­sing care, and postoperative me­dication diffe­red significantly among the two main groups (PELD-MD) (p<0.01). This study demonstrated that PELD is less costly than MD.
