[IgG4-related disease]

ZEHER Margit

[IgG-4-related disease is a clinical entity characterised by significant elevation in serum IgG-4 levels, infiltration of IgG-4+ plasma cells into the involved tissues, enhanced fibrosis, and good therapeutic response to corticosteroids. The IgG-4 associated disease mostly affects two organs. The salivary and lacrimal gland enlargement and inflammation is known as Mikulicz’s disease, which had been previously known as a subtype of Sjögren’s syndrome for a long time. The other commonly involved organ is the pancreas, in which a special form of chronic pancreatitis, namely autoimmune pancreatitis develops. IgG-4 associated disease as a separate disease has been suggested by Japanese authors. Previously published data support the common pathogenesis of autoimmune pancreatitis and Mikulicz’s disease. Besides these two manifestations, similar histological lesions and elevated IgG-4 levels have been demonstrated in many other organs. At present, it is not clearly demonstrated whether IgG-4 syndrome is an autoimmune disorder, and we do not know the exact reason of the elevated IgG-4 levels in patients with this syndrome. IgG-4 is a regulatory immunoglobulin, the main function of which is to decelerate immune responses, thus its pathologic role in tissue destruction is difficult to explain. It is not clear either, whether IgG-4 syndrome is indeed a single disease, or only an example of overlapping symptoms of various diseases. On the basis of the characteristic histological lesions in various organs, IgG-4 syndrome is similar to multi-organ diseases, such as sarcoidosis or vasculitis.]

[Halogen addition and steroid effect]

NAGY Nikoletta, KEMÉNY Lajos

[Among locally administered anti-inflammatory drugs used in dermatology, steroids are among the most commonly applied ones. In everyday practice, choosing the right local steroid preparation is not easy, since more than 50 different local steroid preparations with at least 30 different active ingredients are available. The choice of the local steroid preparation depends on a number of aspescts. It is recommended to apply local steroid preparations that, besides having a strong effect, also have favourable side effect profiles. Moreover, it is subservient to apply local steroids that penetrate deeply into the skin, but have minimal systemic absorption, therefore do not inhibit significantly the hypothalamicpituitary- adrenal axis if administered locally. These characteristics of local steroid preparations are determined by chemical modifications at various positions on the steroid-frame. In this study, we examined the different types of chemical modifications, and the relationship between halogen addition and the characteristics of steroid preparations. We compared the local steroid preparations using the data of previous clinical trials. Regarding the efficacy, safety, tolerability and the risk/benefit ratio, the halogenated steroid preparations were overall superior to nonhalogeneted ones. Among the halogenated preparations, the fluticasone propionate, the mometasone furoate and clobetasol propionate were proved to be the most suitable locally administered, very potent or super potent ones.]

[Diagnosis of diabetes mellitus, treatment and care of diabetic patients in the adulthood - Novelties in the position statement of the Hungarian Diabetes Association, 2011]

JERMENDY György

[The position statement of the Hungarian Diabetes Association has been renewed in 2011. The new version of the position statement, comparing to that of the formerly published one in 2009, implies some new data which are currently reviewed. Besides target value of antidiabetic treatment the importance of the target range is emphasized. Details about the monogenic forms of diabetes and the role of the continuous glucose monitoring system are discussed. A treatment algorithm for type 2 diabetes is published and the use of newly available antidiabetic drugs is summarized. Finally, the importance of the early diagnosis and the prevention of diabetes mellitus are pointed out.]

[What happens to vertiginous population after emission from the Emergency Department?]

MAIHOUB Stefani, MOLNÁR András, CSIKÓS András, KANIZSAI Péter, TAMÁS László, SZIRMAI Ágnes

[Background – Dizziness is one of the most frequent complaints when a patient is searching for medical care and resolution. This can be a problematic presentation in the emergency department, both from a diagnostic and a management standpoint. Purpose – The aim of our study is to clarify what happens to patients after leaving the emergency department. Methods – 879 patients were examined at the Semmel­weis University Emergency Department with vertigo and dizziness. We sent a questionnaire to these patients and we had 308 completed papers back (110 male, 198 female patients, mean age 61.8 ± 12.31 SD), which we further analyzed. Results – Based on the emergency department diagnosis we had the following results: central vestibular lesion (n = 71), dizziness or giddiness (n = 64) and BPPV (n = 51) were among the most frequent diagnosis. Clarification of the final post-examination diagnosis took several days (28.8%), and weeks (24.2%). It was also noticed that 24.02% of this population never received a proper diagnosis. Among the population only 80 patients (25.8%) got proper diagnosis of their complaints, which was supported by qualitative statistical analysis (Cohen Kappa test) result (κ = 0.560). Discussion – The correlation between our emergency department diagnosis and final diagnosis given to patients is low, a phenomenon that is also observable in other countries. Therefore, patient follow-up is an important issue, including the importance of neurotology and possibly neurological examination. Conclusion – Emergency diagnosis of vertigo is a great challenge, but despite of difficulties the targeted and quick case history and exact examination can evaluate the central or peripheral cause of the balance disorder. Therefore, to prevent declination of the quality of life the importance of further investigation is high.]

[The role of sleep in the relational memory processes ]

CSÁBI Eszter, ZÁMBÓ Ágnes, PROKECZ Lídia

[A growing body of evidence suggests that sleep plays an essential role in the consolidation of different memory systems, but less is known about the beneficial effect of sleep on relational memory processes and the recognition of emotional facial expressions, however, it is a fundamental cognitive skill in human everyday life. Thus, the study aims to investigate the effect of timing of learning and the role of sleep in relational memory processes. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning. We used the face-name task to measure relational memory and facial expression recognition. There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. 84 young adults (average age: 22.36 (SD: 3.22), 21 male/63 female) participated in our study, divided into two groups: evening group and morning group indicating the time of learning.

Creutzfeldt-Jakob Disease: A single center experience and systemic analysis of cases in Turkey

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.

Neuroscience highlights: Main cell types underlying memory and spatial navigation

KRABOTH Zoltán, KÁLMÁN Bernadette

Interest in the hippocampal formation and its role in navigation and memory arose in the second part of the 20th century, at least in part due to the curious case of Henry G. Molaison, who underwent brain surgery for intractable epilepsy. The temporal association observed between the removal of his entorhinal cortex along with a significant part of hippocampus and the developing severe memory deficit inspired scientists to focus on these regions. The subsequent discovery of the so-called place cells in the hippocampus launched the description of many other functional cell types and neuronal networks throughout the Papez-circuit that has a key role in memory processes and spatial information coding (speed, head direction, border, grid, object-vector etc). Each of these cell types has its own unique characteristics, and together they form the so-called “Brain GPS”. The aim of this short survey is to highlight for practicing neurologists the types of cells and neuronal networks that represent the anatomical substrates and physiological correlates of pathological entities affecting the limbic system, especially in the temporal lobe. For that purpose, we survey early discoveries along with the most relevant neuroscience observations from the recent literature. By this brief survey, we highlight main cell types in the hippocampal formation, and describe their roles in spatial navigation and memory processes. In recent decades, an array of new and functionally unique neuron types has been recognized in the hippocampal formation, but likely more remain to be discovered. For a better understanding of the heterogeneous presentations of neurological disorders affecting this anatomical region, insights into the constantly evolving neuroscience behind may be helpful. The public health consequences of diseases that affect memory and spatial navigation are high, and grow as the population ages, prompting scientist to focus on further exploring this brain region.

Simultaneous subdural, subarachnoideal and intracerebral haemorrhage after rupture of a peripheral middle cerebral artery aneurysm

The cause of intracerebral, subarachnoid and subdural haemorrhage is different, and the simultaneous appearance in the same case is extremely rare. We describe the case of a patient with a ruptured aneurysm on the distal segment of the middle cerebral artery, with a concomitant subdural and intracerebral haemorrhage, and a subsequent secondary brainstem (Duret) haemorrhage. The 59-year-old woman had hypertension and diabetes in her medical history. She experienced anomic aphasia and left-sided headache starting one day before admission. She had no trauma. A few minutes after admission she suddenly became comatose, her breathing became superficial. Non-contrast CT revealed left sided fronto-parietal subdural and subarachnoid and intracerebral haemorrhage, and bleeding was also observed in the right pontine region. The patient had leucocytosis and hyperglycemia but normal hemostasis. After the subdural haemorrhage had been evacuated, the patient was transferred to intensive care unit. Sepsis developed. Echocardiography did not detect endocarditis. Neurological status, vigilance gradually improved. The rehabilitation process was interrupted by epileptic status. Control CT and CT angiography proved an aneurysm in the peripheral part of the left middle cerebral artery, which was later clipped. Histolo­gical examination excluded mycotic etiology of the aneu­rysm and “normal aneurysm wall” was described. The brain stem haemorrhage – Duret bleeding – was presumably caused by a sudden increase in intracranial pressure due to the supratentorial space occupying process and consequential trans-tentorial herniation. This case is a rarity, as the patient not only survived, but lives an active life with some residual symptoms.
