[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.]

[Cardiovascular risk of non-steroidal antiinflammatory drugs]

FARSANG Csaba

[During the past decade, a number of original publications, reviews and metaanalyses were published on the cardiovascular safety of nonsteroidal antiinflammatory drugs (NSAIDs). As this group of medicines is among the most frequently used ones and many preparations are available over the counter, it seems to be prudent to summarise the most important results on the safety of these drugs, and underline their potentially harmful cardiovascular side effects. Nevertheless, it can also be emphasized that there are substantial differences between different compounds, and the cardiovascular risk does not depend on the ratio of COX-1/COX-2 selectivity. Cardiovascular risk can be increased by all NSAIDs with the possible exception of naproxen.]

[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.]

[Diagnosis and therapy of cerebrovascular diseases - Retrospection to the efforts for managing patients with stroke in the last two decades in Hungary]

NAGY Zoltán

[The first Hungarian guideline regarding management of stroke patients has been published in 1990 (LAM). In the past 21 years, clinical practice in stroke care has improved significantly in Hungary and is currently performed according to evidencebased protocols issued by international and national consensus meetings. Currently the EUSI guideline published in 2008 and the management protocol written in the same year by the board of the Hungarian Stroke Society are followed. The most important changes of the past 20 years in stroke management have been the following: the priority concept and lysis therapy have become common in daily practice, emergency examination has been performed in selected TIA cases and an up-to-date practice has been established in stroke prevention. The increasing number of lysis therapy each year demonstrates an improving organisation of stroke care and improving professional preparedness. In selected stroke centres, all the modern technical facilities are available, on the other hand, substantial development is needed in a number of stroke units. A national stroke registry and quality control are warranted for further professional development in Hungary.]

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.

Late simultaneous carcinomatous meningitis, temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting with mono-symptomatic vertigo – a clinico-pathological case reporT

Although vertigo is one of the most common complaints, intracranial malignant tumors rarely cause sudden asymmetry between the tone of the vestibular peripheries masquerading as a peripheral-like disorder. Here we report a case of simultaneous temporal bone infiltrating macro-metastasis and disseminated multi-organ micro-metastases presenting as acute unilateral vestibular syndrome, due to the reawakening of a primary gastric signet ring cell carcinoma. Purpose – Our objective was to identify those pathophysiological steps that may explain the complex process of tumor reawakening, dissemination. The possible causes of vestibular asymmetry were also traced. A 56-year-old male patient’s interdisciplinary medical data had been retrospectively analyzed. Original clinical and pathological results have been collected and thoroughly reevaluated, then new histological staining and immunohistochemistry methods have been added to the diagnostic pool. During the autopsy the cerebrum and cerebellum was edematous. The apex of the left petrous bone was infiltrated and destructed by a tumor mass of 2x2 cm in size. Histological reexamination of the original gastric resection specimen slides revealed focal submucosal tumorous infiltration with a vascular invasion. By immunohistochemistry mainly single infiltrating tumor cells were observed with Cytokeratin 7 and Vimentin positivity and partial loss of E-cadherin staining. The subsequent histological examination of necropsy tissue specimens confirmed the disseminated, multi-organ microscopic tumorous invasion. Discussion – It has been recently reported that the expression of Vimentin and the loss of E-cadherin is significantly associated with advanced stage, lymph node metastasis, vascular and neural invasion and undifferentiated type with p<0.05 significance. As our patient was middle aged and had no immune-deficiency, the promoting factor of the reawakening of the primary GC malignant disease after a 9-year-long period of dormancy remained undiscovered. The organ-specific tropism explained by the “seed and soil” theory was unexpected, due to rare occurrence of gastric cancer to metastasize in the meninges given that only a minority of these cells would be capable of crossing the blood brain barrier. Patients with past malignancies and new onset of neurological symptoms should alert the physician to central nervous system involvement, and the appropriate, targeted diagnostic and therapeutic work-up should be established immediately. Targeted staining with specific antibodies is recommended. Recent studies on cell lines indicate that metformin strongly inhibits epithelial-mesenchymal transition of gastric cancer cells. Therefore, further studies need to be performed on cases positive for epithelial-mesenchymal transition.

Alexithymia is associated with cognitive impairment in patients with Parkinson’s disease

SENGUL Yildizhan, KOCAK Müge, CORAKCI Zeynep, SENGUL Serdar Hakan, USTUN Ismet

Cognitive dysfunction (CD) is a common non-motor symptom of Parkinson’s disease (PD). Alexithy­mia is a still poorly understood neuropsychiatric feature of PD. Cognitive impairment (especially visuospatial dysfunction and executive dysfunction) and alexithymia share com­mon pathology of neuroanatomical structures. We hypo­thesized that there must be a correlation between CD and alexithymia levels considering this relationship of neuroanatomy. Objective – The aim of this study was to evaluate the association between alexithymia and neurocognitive function in patients with PD. Thirty-five patients with PD were included in this study. The Toronto Alexithymia Scale–20 (TAS-20), Geriatric Depression Inventory (GDI) and a detailed neuropsychological evaluation were performed. Higher TAS-20 scores were negatively correlated with Wechsler Adult Intelligence Scale (WAIS) similarities test score (r =-0.71, p value 0.02), clock drawing test (CDT) scores (r=-0.72, p=0.02) and verbal fluency (VF) (r=-0.77, p<0.01). Difficulty identifying feelings subscale score was negatively correlated with CDT scores (r=-0.74, p=0.02), VF scores (r=-0.66, p=0.04), visual memory immediate recall (r=-0.74, p=0.01). VF scores were also correlated with difficulty describing feelings (DDF) scores (r=-0.66, p=0.04). There was a reverse relationship bet­ween WAIS similarities and DDF scores (r=-0.70, p=0.02), and externally oriented-thinking (r=-0.77,p<0.01). Executive function Z score was correlated with the mean TAS-20 score (r=-62, p=0.03) and DDF subscale score (r=-0.70, p=0.01) Alexithymia was found to be associated with poorer performance on visuospatial and executive function test results. We also found that alexithymia was significantly correlated with depressive symptoms. Presence of alexithymia should therefore warn the clinicians for co-existing CD.

[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.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.
