[INTRODUCTION - In patients presenting with isolated tissue perfusion disturbance without large vessel involvement the examination of hand microcirculation is of major importance. In our study we present the results of three examination methods used for hand perfusion monitoring which measure the tissue microcirculation in different depths. PATIENTS AND METHODS - We examined 58 primary Raynaud's patients using capillary microscopy, laser doppler perfusion imaging and hand perfusion scintigraphy with Tc-99m-DTPA. From our patients 38 were smokers, 42 patients frequently suffered from headache. For the validation of our laser Doppler results we involved into the study also 16 non-smoker healthy volunteers. For the standardisation of the results the studies were performed in a climatised room. During the laser examination we performed and analysed also the post-occlusion hyperaemia test. RESULTS - In the majority of our patients no morphological alterations were found with capillary microscopy. In primary Raynaud’s patients the perfusion values measured with laser-Doppler scanner in basic condition were significantly lower both in fingers’ and palm’s regions compared to healthy controls. In the primary Raynaud’s group the smokers had significantly lower hyperaemic response than the non-smokers and we measured also significantly lower FPR (finger-to-palm ratio) values with hand perfusion scintigraphy. Both with laser doppler imaging and hand perfusion scintigraphy there was no difference between the values measured in patients with or without headache. CONCLUSIONS - We consider of benefit the functional examination of hand circulation in all diseases involving the hand microcirculation.]

[Pathomechanism of Crohn’s disease and ulcerative colitis]

GÁL István, CSIKI Zoltán, SZEGEDI László, G. KISS Gyula

[The two archetypes of inflammatory bowel diseases, Crohn’s disease (CD) and ulcerative colitis (UC) have a considerably high prevalence and chronic morbidity, and thereby a striking public health relevance amongst the maladies involving the gastrointestinal tract. Unveiling their pathogenesis can be the key for the development of successful therapeutic approaches. Our view of these diseases has undergone radical changes in the past few years, and the latest discoveries have shed new light upon their pathomechanism. A multifactorial view is appropriate when explaining their pathogenesis, although certain factors are seemingly of particular importance.]

[Animal models of experimental arthritis can be used to understand pathophysiology of the arthritic processes in patients and provide opportunity to develop new therapeutic approaches. The animal models can be divided into different categories based on the pathomechanism of the model and on the features that resemble human inflammatory joint diseases. This review provides an overview of the most widely used types of experimental arthritis models emphasizing their advantages and limitations in the basic arthritis research.]

[Immune-dysfunctions in patients with Hodgkin’s lymphoma being in a long lasting complete remission]

ALEKSZA Magdolna, KERESZTES Katalin, BARÁTH Sándor, SIPKA Sándor, ILLÉS Árpád

[OBJECTIVES - Immunosuppression has long been known to be associated with Hodgkin’s lymphoma. The authors report on immunologic abnormalities with special focus on cellular immunity in patients with Hodgkin’s disease in complete remission. METHODS - We determined the proportion of the lymphocytes subpopulations, activated T cells, CD4+/CD25+ suppressor T cell population and intracytoplasmic cytokines by flow cytometry. The soluble cytokines were measured by classical ELISA technique. RESULTS - Based on lymphocyte cell surface antigen expression the subpopulations were as described in the literature, however a unique elevation of CD4+/CD25+ cell fraction was detected. The decreased amount of IFN-γ in the serum suggest Th2 dominance, but reduced intracellular IL-4 production in both CD4+ and CD8+ cells results from Th1 dominance. These results somewhat contrary but can not be completely compared as in vivo and in vitro techniques used for the analysis are not identical. However a constant elevation concentration and expression of IL-10 and TGF-β is observed. CONCLUSION - These alterations may reflect the existence of an immunosuppressive state also in the peripheral blood of Hodgkin’s lymphoma patients not only in the lymph nodes.]

[Hand perfusion scintigraphy in primary and secondary Raynaud's syndrome]

GARAI Ildikó, GALUSKA László, VARGA József, SZŰCS Gabriella, CSIKI Zoltán

[INTRODUCTION - The aim of the study was to investigate the circulatory characteristics of primary and secondary Raynaud’s syndrome patients using the hand perfusion scintigraphic method developed by the Nuclear Medicine Department of the DUMHC. PATIENTS AND METHODS - The authors examined 84 patients presenting classical symptoms of the disease: episodic ischemia with three-phase color change of the fingers. After visual evaluation theyanalyzed the obtained images quantitatively, using of the finger/palm ratio. Statistical analysis comparisons were made between the clinically separated primary and the secondary Raynaud's group. RESULTS - With the visual evaluation regional perfusion disturbances were frequently found in the secondary group - 37 from 51 patients - while only 2 from 33 patients in the primery group; the difference was statistically significant (p<0,001). The results of the quantitative analysis showed that the finger/palm ratio (FPR) values were significantly lower (p<0.05) in primary Raynaud’s group. In the FPR values there were not any differences between genders or the fingers of the right and left hands. CONCLUSIONS - The hand perfusion scintigraphy applying Tc-99m-DTPA is a noninvasive, cost effective diagnostic tool, which reflects objectively the global and regional microcirculatory abnormalities of the hands, and offers quantitative data for the follow-up.]

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.

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.
