[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. ]

USLU Ilgen Ferda, ELIF Gökçal, GÜRSOY Esra Azize, KOLUKISA Mehmet, YILDIZ Babacan Gulsen

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.

[What may hurt the patient’s leg? Lower extremity ischaemia]

FENDRIK Krisztina, BIRÓ Katalin, KOLTAI Katalin, ENDREI Dóra, TÓTH Kálmán, KÉSMÁRKY Gábor

[Peripheral artery disease (PAD) is of high prevalence, and one of the most common clinical manifestations of the atherosclerosis beside ischaemic heart disease and cerebrovascular disease. PAD should be considered as a systemic disease, PAD patients have two times higher ten-year cardiovascular mortality than the normal population. For these reasons, the early recognition of the disease, the appropriate secondary preventive medical and non-medical therapy are of great importance. Risk stratification, proper physical examination, ankle pressure, ankle-brachial index, toe pressure, transcutaneous partial tissue oxygen pressure measurement and duplex ultrasound are the cornerstones to an early diagnosis. This summary aims at calling attention to the fact that lower extremity pain can not only be caused by musculo­sceletal diseases but limb and/or life-threatening limb ischaemia can be revealed in the background. ]

[Juvenile idiopathic arthritis: from diagnosis to treatment]

MOSDÓSI Bernadett

[Juvenile idiopathic arthritis is a heterogeneous group of diseases that is one of the most common chronic diseases of childhood. It begins before 16 years of age, the etiology is unknown, it is persisting for at least 6 weeks and other pathologic conditions could be excluded. Juvenile idiopathic arthritis includes several diseases categories, each of them have distinct methods of presentation, clinical symptoms, pathogenesis and treatment options. Recent advances in the understanding of the immunological pathogenesis of the diseases have led to dramatic improvements in treatment. Although the management is using a multidisciplinary approach, the disease often persist into adulthood and can cause significant long-term morbidity and physical disability. Our article discusses the classification, clinical manifestations, differential diagnosis, treatment and complications of juvenile idiopathic arthritis. ]

[Mobbing and bullying among physicians - when colleagues become enemies]

KAPOCSI Erzsébet

[Workplace mistreatment, mobbing, bully-ing, or psychoterror has become a prioritised field of research in social sciences in the past two-three decades. Mobbing means more than a simple conflict situation between two individuals; it is a complex problem that could and should be investigated in various individual and organisational contexts. In spite of its large-scale theoretical and empirical research, the phenomenon still does not have a uniform definition; it is most commonly de-scribed via its social manifestations. Although the interpersonal constellation of mobbing is diverse, its trigger factors, stages and participants show similar patterns. The description and the evaluation of consequences is also uniform in the literature: workplace mobbing is accompanied by considerable health impairment, and it has severe psychosomatic and mental health effects on both the targeted individuals and the whole community. The latter group has to deal with poor performance, impaired morale and dissatisfaction. All these factors add up and lead to significant financial damage as well. The prevalence of mobbing is especially high in health care. Hierarchy, continuous overload, as well as emotional and physical stress all favour the development of mobbing. In turn, the professional-social culture of medicine that is based on traditions contributes to its acceptance, understatement and denial. The first time medical students have to face psychoterror is typically during their university years. The positive aspects of socialisation and finding their vocation cannot always compensate for the negative experiences. The model role of physicians, their behaviour towards colleagues and students can be protective, but it can also trigger further mobbing. Prevention is essential both at the organisational and individual level, and it requires complex measures whose effect will only be felt in the long term. ]

[Depression from the aspect of polygenic studies: the role of the relationship between genes and the environment]

GONDA Xénia

[Depression is a multifactorial disease with both genes and environmental factors as well as complex relationships between these factors playing a role in its background. However, in spite of several decades of research no genetic variants playing a straightforward and robust role in the background of depression have been identified. One reason behind this is the genetic and biological heterogeneity of depression, while another is that in the majority of studies environmental effects interacting with genetic variants have not been considered which may mask important genetic effects. Furthermore, relative contribution of genetic and environmental factors may vary in case of different manifestations and subtypes of depression which has not only etiopathological relevance but may also influence choice and efficiency of treatment. Consideration of heterogeneity of depressive syndromes, as well as environmental effects in case of both candidate gene and whole genome association studies, and qualitative analysis of environmental effects in depression and antidepressant research may extend our existing knowledge concerning the pathophysiology of depression and may also aid identification of new antidepressive therapeutic targets. ]

[Gout, hyperuricaemia and cardiovascular risk - Effects of allopurinol]

KÉKES Ede

[Hyperuricemia has an increasing clinical relevance due to its pathomechanism and its presence and adverse effects on cardiovascular, metabolic and renal diseases today. Its presence is a world phenomenon and in our country, we have seen increasing incidence rates during the screening surveys in recent years. Convincing evidence suggests that the high uric acid values in cardiovascular and renal diseases is an independent risk factor for CV mortality and their clinical manifestations. Experimental and clinical evidences indicates that in addition to gout, all high uric acid levels should be considered to initiate the XO inhibitor allopurinol treatment. Recently, in some diseases, in the treatment of the underlying disease (especially elderly hypertension, ischemic heart disease, chronic heart failure, chronic kidney failure) is also considered as an adjunct therapy.]

[Organic and non-organic perspectives in feeding and eating disorders under three years of age]

SCHEURING Noémi, DANIS Ildikó, KAROLINY Anna, SZABÓ László

[Providing optimal nutrition to infants and toddlers is a critical issue for both parents and experts. Besides the quality and quantity of food, indications of feeding behaviour such as feeding method and acceptance by the child are also crucial when determining feeding issues. The development of self-feeding is a significant part of the healthy somatomental development of a toddler between the age of 0-3 years. Efficient treatment of infants and toddlers with feeding disorders is often challenging in clinical practice. These symptoms frequently appear together with additional behaviour disorders, therefore functional reasons have to be taken into consideration in such cases. Due to the complexity of manifestations, applying tools beyond me­dical competence and involvement of special related professions are necessary. The general diagnostic systems of BNO-10 (International Classification of Diseases) and DSM-V (Statistical Manual of Mental Disorders) which are also applied in our country cannot be used appropriately for clear classification of early childhood feeding disorders and for examination of their backgrounds. DC:0-3R (Diagnostic Classi­fication of Mental Health and Develop­men­tal Disorders of Infancy and Early Childhood- Zero to Three), generally used in Anglo-Saxon countries, can be considered as a complex diagnostic system. Using the DC:0-3R classification system (1), we will present six types of feeding disorders affecting children between the age of 0-36 months in which organic and functional origins have been examined as well. In our article we argue for the complex, psychosomatic interpretation and treatments of early childhood feeding disorders.]

[Antibody deficiencies, investigation, therapy]

MOSDÓSI Bernadett, NYUL Zoltán

[Inborn antibody deficiencies represent the most common primary immunodeficiency diseases. This heterogeneous group of disorders is characterised by insufficient antibody production resulting from a genetic defect of B cell differentiation or from abnormal interactions between B and T cells. The clinical manifestations are recurrent, often severe upper and lower respiratory tract infections, but chronic diarrhea and autoimmune diseases might also occur. Timely diagnosis and therapy significantly decrease morbidity, thus increasing life expectancy and improve quality of life.]

[Reversible hepatocerebral degeneration-like syndrome due to portovenous shunts]

SIBEL Güler, UFUK Utku, AHMET Tezel, ERCÜMENT Ünlü

[Ataxia and tremor are rare manifestations of hepatocerebral degeneration due to portovenous shunts. Ammonia is a neurotoxin that plays a significant role in the pathogenesis of hepatic encephalopathy. A 58-year old male patient was assessed with the complaints of gait disturbance, hand tremor, and impairment of speech. His neurological examination revealed dysarthric speech and ataxic gait. Bilateral kinetic tremor was noted, and deep tendon reflexes of the patient were hyperactive. Serum ammonia level was found to be 156.9 μg/dL. Cranial magnetic resonance (MR) imaging revealed increased signal intensity in bilateral globus pallidus on T1-weighted axial sections, and bilateral prominent hyperintense lesions in the middle cerebellar peduncles on T2-weighted axial sections. On his abdominal MR portography, multiple portohepatic venous collaterals were noted in the right and left lobes of liver parenchyma in 2D FIESTA axial MR sections. To our knowledge, we reported the first case of acquired hepatocerebral degeneration presenting with cerebral symptoms without any hepatic findings in which clinical improvement was noted, and hyperammonemia disappeared following medical treatment.]
