[This communication intends to give an overview of the cell biological changes that maintain the underlying pathobiological events (invasive growth, metastasis formation, angiogenesis) of tumour progression. The multiple and continuously accumulating mutations of the cells affected by the etiological factors are collectively termed the malignant genotype of the tumour cells, which varies greatly on one hand, but, on the other hand, they are invariably related to an increased survival potential or invasive growth. Properties of the tumour cells produced by the malignant genotype, including immortalization, reduced apoptosis, uncontrolled proliferation, adaptation to hypoxia, resistance, metastatic potency and production of biopolymers harmful to the body are collectively termed the malignant phenotype. The malignant phenotype shows a remarkable variance among the tumours, also, certain forms are present in all stages, while others only appear in specific stages of tumour progression. Consequently, beside clinico-pathological examinations, the identification of the underlying malignant phenotype in each tumour allows a better prediction of tumour progression and a targeted planning of therapy.]

[INTRODUCTION - Henoch-Schönlein purpura is a systemic small vessel vasculitis characterized by vascular and/or mesangial IgA deposits, primarily affecting the vasculature of the skin, joints, kidneys and gastrointestinal tract. Gastrointestinal findings of various severity occur in 50 to 85% of the cases. We report on a 70-year-old woman who developed ileocaecal invagination and upper gastrointestinal haemorrhage as manifestations of Henoch-Schönlein purpura. CASE REPORT - The patient presented with two days history of palpable purpuric rash localized on the lower extremities. Based on the result of the skin biopsy, which showed leukocytoclastic vasculitis, IgA and C3 deposits, Henoch-Schönlein purpura was suspected. On the second night after admission colicky abdominal pain, vomiting and diarrhoea developed. Radiological examination showed an ileocaecal invagination and since symptoms deteriorated caecum resection and ileo-ascendestomy was performed. On the third postoperative day the patient became oligo-anuric, which was attributed to her Henoch-Schönlein disease, and systemic steroid pulse therapy was given. One month after the admission the patient experienced haematochezia. Emergency upper endoscopy revealed petechiae, haemorrhagic erosions and mucosal oedema, primarily in the descending part of the duodenum. Since these lesions were also considered as presentations of Henoch-Schönlein disease, another bolus of parenteral steroid was administered. Upper endoscopy repeated 3 days later showed remarkable improvement of the gastric and intestinal lesions. CONCLUSION - Gastrointestinal symptoms are common manifestations of Henoch-Schönlein purpura, thus their recognition, in which endoscopy plays a crucial role, is of major importance. Methylprednisolone pulse therapy is an effective therapeutic option not only in the management of severe renal or joint symptoms, but also in the treatment of gastrointestinal manifestations.]

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.

[Mental and physical health in light of health behaviours among sexual and gender minorities]

GUBÁN Zsuzsanna, CSEKÔ Csilla, SZÉL Zsuzsanna

[In a large proportion the reason behind enlisting both primary and secondary care are psychophysiologic disorders or symp­toms. In this current study we reviewed the literature regarding the physical and mental health of a subpopulation (sexual and gender minorities) and their patterns of health behavior. The literature examined in our study contains publications from January of 2009 to March of 2019. Based on the minority stress theory and the biopsychosocial model, the people from sexual and gender minorities face increased level of stress which affects their health and health behaviour in a negative way. Because of the factors mentioned above this group is more exposed to certain illnesses than the majority society – such conditions are cardiovascular diseases, lung diseases and several types of tumors and cancer. Furthermore the excess stress affects their psychological wellbeing and mental health. Summarizing the literature regarding the health and health behavior of people belonging to sexual and gender minorities our aim was to create an inventory of information for health care workers to help enhance the quality of care the members of these minorities receive. It could also support developement of cultural competence for the circle of professionals in education, law enforcement agencies, social care and health care system, in additional it might decreas health inequity.]

Purpose - In cancer patients, an ischemic stroke can be seen as both a direct effect of cancer and a complication of treatment. This condition can negatively affect the follow-up and treatment of these patients. For this research, we aimed to evaluate the clinical features, stroke types and etiological features of ischemic stroke patients with histories of cancer or found to have cancer during the aetiological investigation. Materials and methods - We retrospectively evaluated 100 patients (57 males, 43 females) who were hospitalized with acute stroke and determined to have the presence of cancer or a cancer history during the aetiological investigation between 2011 and 2016. All the demographic features, stroke types and localizations, National Institutes of Health Stroke Scale (NIHSS) scores, Rankin Scale scores, durations of cancer and cancer treatments were recorded. Results - The mean age of the patients was 67.07 ± 10.9 years old, the median NIHSS score was 5, and the median Rankin Scale score was 4. While 79% of patients had ischemic stroke risk factors, 21% did not. Atherosclerotic stroke was the most common stroke type (49%, n=49) and cryptogenic strokes were detected in 21% (n=21). In addition, 63% of the patients had chronic cancer (later than 6 months), 31% of the patients had recent cancer histories (less than 6 months), and 29% of the patients had metastases. Among all the malignancies, lung cancer (n=23), gastrointestinal cancer (n=20) and gynaecological-breast cancer (n=16) were the three most common. Moreover, 37% of the patients underwent chemotherapy, 29% underwent radiotherapy, and 88% of the patients had Carotid/Vertebral Doppler USG abnormalities. Conclusion - Similar to what is stated in the literature, an atherosclerotic stroke was the most common type of stroke in the cancer patients. Stroke risk factors were not detected in 21% of the patients, and in the majority of the patients, atherosclerotic changes in the carotid artery were observed in the Doppler examinations. In the aetiology and prognosis of ischemic stroke, it is important to keep in mind the existence of cancer in addition to the classical stroke risk factors.

GABAB receptor (gamma-aminobutyric acid type B receptors - GABABR) encephalitis is a rare manifestation of autoimmune encephalitides. We report four cases - including the first two Hungarian patients - with some peculiar features. One patient developed subacute disorientation and almost complete loss of short-term memory, but no epilepsy. Without immunotherapy, his memory spontaneously improved up to mild cognitive impairment in six weeks. GABABR antibodies persisted in his serum, and 18 months later, FDG-PET detected abnormal mediastinal lymph nodes and small cell lung cancer (SCLC). Another patient had persistently decreased sodium content in the peripheral blood. In those three patients who died, CSF was abnormal, but CSF was not pathological in the patient, who spontaneously improved. Brain MRI indicated signal intensity changes in the medial temporal areas in three cases. SCLC was found in three patients. Only the patient, who spontaneously improved, survived for more than 24 months. In summary, our cases show that (i) GABABR encephalitis may develop without epilepsy; (ii) the severe short-term memory loss can spontaneously improve; (iii) persistent hyponatremia can be present in the blood; (iv) the patient with benign course without epilepsy and CSF abnormality survived; (v) spontaneously remitting encephalitis can precede SCLC by 1.5 year, which emphasizes that repeated search for cancer is of paramount importance even in cases with spontaneous improvement.

Wnt pathway markers in low-grade and high-grade gliomas

NAGY Ádám, TOMPA Márton, KRABÓTH Zoltán, GARZULY Ferenc , MARÁCZI Alexandra , KÁLMÁN Bernadette

Aberrant activation of the Wnt pathway contributes to differentiation and maintenance of cancer stem cells underlying gliomagenesis. The aim of our research was to determine as to what degrees some Wnt markers are expressed in gliomas of different grades, lineages and molecular subtypes. Nine grade II, 10 grade III and 72 grade IV surgically removed, formalin-fixed paraffin-embedded glioma specimens were included. Mutation status of IDH1 codon 132 was defined by immunohistochemistry and pyrosequencing in all tumors. Grade II and III astrocytic and oligodendroglial tumors were further tested for the expression of p53 and ATRX by immunohistochemistry, and codeletion of 1p19q by fluorescent in situ hybridization. Expression levels of the non-canonical Wnt5a and Fzd2, and the canonical Wnt3a and beta-catenin Wnt pathway markers were determined by immunohistochemistry, and compared between subgroups stratified according to grade, lineage and the presence or absence of IDH1 R132H/C mutations. In the normal brain – grade II-IV glioma comparisons, a gradual increase was observed for the expressions of Wnt5a, Wnt3a, Fzd2 and beta-catenin. In the astroglial and oligodendroglial lineages of grade II and III gliomas, only the Wnt5a expression was significantly higher in the astroglial subgroup. Stratification according to the IDH1 status resulted in a significant increase of the Wnt3 expression in the wild type grade II-IV gliomas. These data extend previous observations and show a correlation of Wnt pathway activity with glioma grade. Further investigations of the Wnt marker expression regulation according to glioma lineage or IDH gene mutational status are in progress by using more exact molecular approaches.
