[INTRODUCTION AND AIM - During rou­tine blood panel testing, large amounts of bio­medical data are collected in Hungary and in all over the world. The aim of our - ethically approved - exploratory medical data analysis was to examine whether the analysis of correlations among several variables in a real-life, non-random blood panel data leads to meaningful results. DATA AND METHODS - In a retrospective study 2,292,199 anonymous routine blood panel data points were analyzed. Rank correlation was used between variables with more than 10,000 data points and strong (|ϱ|>0.5, p<0.001) relationships were visualized and interpreted. RESULTS - Similar laboratory values, effects of diseases affecting the same organ, as well as well-known medical interrelationships were shown between the examined laboratory parameter-pairs. DISCUSSION - Our exploratory data analysis shows that despite the non-random nature of the big blood panel sample, well-known medical correlations were very well detectable. Based on the results further re­search - with the inclusion of additional variables - seems reasonable and meaningful with due caution.]

[Praeeclampsia - 2019]

TAMÁS Péter, KOPPÁN Miklós

[Preeclampsia remains one of the most serious gestational diseases. Accumulating data support the opinion that the pathogenesis of preeclampsia (gestational hypertension + organ dysfunction) is not homogenous. The early-onset (onset of clinical phase before the 34th gestational week) type is a placental disease in which hypertension and organ dysfunctions are due to vasoconstriction and microthrombosis. The late-onset form is a maternal disease in which water retention - in connection with obesity - beyond the given vascular capacity may be an important progenitor of the clinical signs. These considerations should also influence the strategy of the treatment. ]

[The adverse effects of smoking on our respiratory system based on data of the Hungarian Public Health Screening 2010-2018 ]


[The regular smoking with or without clinical symptoms causes structural changes in the lung tissue and this is reflected in res­pi­ratory function tests. During the last 9 years of Hungary's comprehesive health promotion screening (MÁESZ) between 2010 and 2018, spiro­metric examinations (PEF, FEV1, MEF25-75, FVC) were performed on 70822 women and 60187 men. We used the percentage of predictive values in the analysis to describe the deviation from normal. The carbon monoxide (eCO) content measurement of the exhaled air (in ppm) was performed on 24899 women and 22340 men. The COPD Evaluation Ques­tionnaire (CAT) was completed by 4166 wo­men and 3170 men. All four parameters of spirometry showed lower values for smokers in both sexes, but in men they were lower than in women. Ageing lowered significantly the values. The rate of changes from normal predictive values and the difference between smokers and non-smokers was the highest for MEF25-75 and FVC. The expiratory CO content (eCO) was significantly higher in smokers than in non-smokers in all age groups. In smokers, the incidence in percent of abnormal CAT score was significantly higher. Respiratory screening tests reveal the harmful effects of smoking, even without clinical symptoms, and indicate the risk of developing COPD.]

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

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.

[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.]
