[Covid-19 associated neurological disorders]

SZÔTS Mónika, PÉTERFI Anna, GERÖLY Júlia, NAGY Ferenc

[The clinical signs of SARS-CoV-2 infection has become more recognisable in recent times. In addition to common symptoms such as fever, cough, dyspnea, pneumonia and ageusia, less common complications can be identified, including many neurological manifestations. In this paper, we discuss three Covid-19 associated neurological disorders (Case 1: Covid-19 encephalitis, Case 2: Covid-19 organic headache, Case 3: SARS-CoV-2-infection and ischaemic stroke). We emphasize in our multiple case study that during the present pandemic, it is especially important for neurologists to be aware of the nervous system complications of the virus infection, thus saving unnecessary examinations and reducing the frequency of patients’ contact with health care personnel. ]

Electrophysiological investigation for autonomic dysfunction in patients with myasthenia gravis: A prospective study

NALBANTOGLU Mecbure, AKALIN Ali Mehmet, GUNDUZ Aysegul, KIZILTAN Meral

Myasthenia gravis (MG) is an autoimmune disorder of neuromuscular transmission. Autonomic dysfunction is not a commonly known association with MG. We conducted this study to evaluate autonomic functions in MG & subgroups and to investigate the effects of acetylcholinesterase inhibitors. This study comprised 30 autoimmune MG patients and 30 healthy volunteers. Autonomic tests including sympathetic skin response (SSR) and R-R interval variation analysis (RRIV) was carried out. The tests were performed two times for patients who were under acetylcholinesterase inhibitors during the current assessment. The RRIV rise during hyperventilation was better (p=0.006) and Valsalva ratio (p=0.039) was lower in control group. The SSR amplitudes were lower thereafter drug intake (p=0.030). As much as time went by after drug administration prolonged SSR latencies were obtained (p=0.043).Valsalva ratio was lower in the AchR antibody negative group (p=0.033). The findings showed that both ocular/generalized MG patients have a subclinical parasympathetic abnormality prominent in the AchR antibody negative group and pyridostigmine has a peripheral sympathetic cholinergic noncumulative effect.

[The first Hungarian patient with Guillain-Barre syndrome after COVID-19]

NADIM Al-Muhanna, BÉRES-MOLNÁR Katalin Anna, JARECSNY Tamás, FOLYOVICS András

[Guillain-Barré syndrome (GBS) is a sporadic, relatively rare disease. In serious cases, it can lead to respiratory failure and death. The correlation between SARS-CoV-2 and the risk of GBS is not yet known. COVID-19-associated prolonged pulmonary complications could be worsened by the potential airway interference caused by GBS. The literature is inconsistent whether SARS-CoV-2 virus has direct or indirect effect on the onset of GBS. The authors describe the medical history of the first published GBS patient in Hungary with a preceding confirmed COVID-19 infection. The trigger role of COVID-19 infection is assumed because of the subsequent development of GBS after COVID-19 infection. So far none of the patients in the literature (including this patient) had positive PCR of SARS-CoV-2 virus from the cerebrospinal fluid.]

[Cases of inborn errors of metabolism diagnosed in children with autism ]

ÇAKAR Emel Nafiye, YILMAZBAŞ 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.]

[Complication of the Metabolic Syndrome in Women with Polycystic Ovary Syndrome]

KOMLÓSI Kálmánné, KISS Sarolta, FERENCZY Mónika, MÁTÉ-PÓHR Kitti, PAKAI Annamária

[In our research we compared whether pregnant women with polycystic ovary syndrome or the mothers who were healthy through pregnancy has a higher risk to develop high BMI, metabolic syndrome, preeclampsia, polyhydramnion and macrosomia. Our research is a retrospective, cross-sectional study. In the random sampling within the target group, the target group was diagnosed with PCOS (n=50) and the control group was mothers who had undergone uninterrupted pregnancy (n=50). The exclusion criterion is the coexistence of other endocrine disease that may affect the parameters under consideration, in addition to the control group the diagnosis of PCOS. With IBM SPSS for Windows 22.0, we applied two-sample T-test and Khi2 test (p<0.05). The BMI values ​​measured in the PCOS study group are higher than in the control group (p<0,05). Pregnant women with PCOS has a higher risk of developing high blood pressure, and high cholesterol (p<0,05). The difference between the two groups can not be considered significant for the development of proteinuria and oedema. Emphasis should be placed on PCOS gravid care, early detection of metabolic disturbances, accurate documentation, and elimination of complications and illnesses associated with the disease.]

[Possibility of ARNI (angiotensin receptor-neprilysin inhibitor) treatment in hypertension]

KÉKES Ede

[The natriuretic peptide (NP) is an important endocrine, autocrine and paracrine system that is in constant interaction with RAAS and the sympathetic nervous system in order to ensure a continuous cardio-renal homeostasis. In abnormal conditions – if the pressure/volume load develops in the heart or there are some disorder in the vascular tone or in sodium-water balance, the NP system triggers the body’s defense mechanism. The neutral endopeptidase (NEP) inactivates the vasodilator NPs, bradykinin and vasoconstrictor angiotensin II and endothelin I as well. From this knowledge, the idea that inhibition of the effect of NEP (NEPg) offers a potentially beneficial option in the treatment of heart failure and hypertension was initiated, only the stimulatory effect of angiotensin II needs to be blocked. After a lengthy search, they arrived at a dualacting molecule with a beneficial effect of NEP inhibition (secubitrile) and the angiotensin II AT1 receptor antagonist valsartan (ARNI). Several clinical studies have shown that ARNI alone and in combination with other antihypertensive agents significantly reduces SBP and DBP in hypertensive patients. Its effect is also present in isolated systolic hypertension and in chronic kidney disease with high risk. Do not administer with an ACE inhibitor. Based on clinical experience to date, there is a logic expectation that ARNI will also be classified as a useful antihypertensive agent in the near future.]

[Arrhythmias in hypertension]

ZÁMOLYI Károly

[Hypertension has been recognized as the principal and most common risk factor and underlies many cardiovascular (CV) conditions, including heart failure, coronary artery disease, stroke, and chronic renal failure. Different cardiac arrhythmias have been recognized as clinical manifestations of hypertensive heart disease, related to structural and functional pathophysiological changes of the myocardium, which may predispose to arrhythmias, most commonly atrial fibrillation. Both supraventricular arrhythmias and ventricular arrhythmias may occur in the hypertensive patients, especially when associated with left ventricular hypertrophy or heart failure.]

[30 year history of surgery and the surgeon’s future ]

KUPCSULIK Péter

[During the past 3 decades, laparoscopic surgery has launched a revolution in operative medicine. The German gynaecologist Kurt Semm transformed the diagnostic laparoscopy for therapeutic procedure, as he performed the first laparoscopic ap­pen­dectomy. The surgeon Erich Mühe contributed with laparoscopic cholecystectomy to the set of surgical instruments. All over the world, a wide spectrum of laparoscopic procedures has been app­lied. Several laparoscopic procedures are now preferred over open approaches. Morbid obesity is associated with significant comorbidity and mortality. In­suffi­ciency of dietary measures lead to development of surgical interventions that resulted in unexpected excellent outcomes. “Metabolic surgery” was born. New methods and rising market of socio-medical requirements inspired progress in plastic surgery. Thanks to innovations in technology, reconstructive breast surgery has opened new ways. In the 1990s the prototype of “mas­ter–slave” robot controlled by a surgeon was constructed. Future of robotic surgery depends on cost reduc­tion, development of new technologies and creating the best applications. Coo­pe­ra­tion with partner medical specialities is essential for further development in surgery. Despite of obvious impact of new technologies the surgeon's way of thinking, personal qualities decision-making and professional knowledge remain cru­cial for further evolution. ]

[Tumor induction by chemotherapy]

[Without chemotherapy, the fi ve-year survival rate of detected cancers would be between 0 and 15%, depending on the tumor, and between 17 and 85% with current therapy. Several warnings call attention to the dangers of chemotherapy-induced side effects, most notably the potential for tumor-inducing ability, which can affect 5-10% of patients who have recovered beyond fi ve years. Some systematically applied drugs used in chemotherapy (alkylating agents, etoposide, arsenic trioxide) are able to cause mutations in healthy cells of the patients, increasing the likelihood that the mutated cells will start a later (secondary) tumor formation. In addition to mutagenic effects, some chemotherapeutic agents exert their effects on normal myeloid and epithelial cells of the body, which, by altering the tissue microenvironment, create the potential for malignant transformation. Tumor-associated macrophages (TAMs), which can alter gene expression patterns by tumor cell secreted factors and promote the survival and invasiveness of tumor cells by pro-carcinogenic signals, are very important in this process. It is of utmost importance that doctors, pharmacists, technicians and nurses working with cancer-causing materials do not come into direct contact with dangerous substances and wear appropriate protective equipment.]

[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. ]
