[Medical aid in dying or physician assisted suicide]

KŐMÜVES Sándor

[The paper reflects upon the process in which physician assisted suicide, as it is traditionally called, is being reinterpreted. First, changes in word usage shall be demonstrated by examples taken form the relevant US laws and statements of prestigious US organisations. Then the interpretive possibilities of suicide, as it is traditionally called, and their consequencies are discussed. In this context the present state of art of the Hungarian criminal law is briefly presented. Finally some remarks on the normative element of the practice are made. ]

[Differential diagnosis and treatment of hyponatraemia]

NÉMETH Zsófia, DEÁK György

[Hyponatraemia (serum sodium concentration < 136 mmol/l) is the most frequent electrolyte abnormality that inceases the risk of both in-hospital, and outpatient mortality. Antidiuretic hormone action or low glomerular fitration rate or low excretable osmoles or their combination are involved in its pathogenesis. Differential diagnosis is based on medical and medication histories, serum- and urine osmolality and urine sodium concentration. Measurement of fractional excretions of urea and uric acid help identifying low effective circulting volume, renal hypoperfusion. Symptomatic hyponatraemia or an acute decrease of serum sodium concentration exceeding 10 mmol/l should be treated with 3% NaCl to avoid impending threat to life. The principles of the treatment of chronic hyponatraemia are restriction of water intake and elimination of etiologic factor(s) (eg. medications - most often thiazides). In case of contracted axtracellular volume, isotonic saline should be given. In case of euvolaemia, restriciton of water intake is fundamental. In case of expanded extracellular volume, (heart failure, liver cirrhosis, nephrosis), water and NaCl intake should be restricted along with aldosteron antagonist and loop diuretic therapy. In chronic hyponatraemia, the rise of serum sodium concentration should not exceed 10 mmol/l during the first 24 hours and 8 mmol/l/day thereafter. ]

[„Is it worth the while to be further occupied with the history of medicine? - letter by Gyula Magyary-Kossa to Bódog Csajkás]

PERJÁMOSI Sándor

[In 1941 Bódog Csajkás, a young historian of medicine at the beginning of his career, wrote a letter to Gyula Magyary-Kossa, the most outstanding character of Hungarian medical historiography and sent him some of his works. In this letter he asked if there was a point in further devoting himself to the history of medicine. In a short and encouraging answer Magyary-Kossa urged the young man to continue with his efforts. ]

[Depression in medical practice - the possibilities of diagnosis and treatment]

OSVÁTH Péter

[Nowadays, there is an increasing incidence of depressive mood disorders, so we have more and more depressed patients in everyday clinical practice. Unfortunately, in many cases, this is not recognized and thus the treatment of depressed patients is not adequately addressed. Untreated depression not only increases the burden of the patient and his environment, but leads to serious and dangerous psychic and somatic complications. However, with modern and complex psychopharmacological, psychotherapeutic and sociotherapeutic methods, depressive mood disorders can be effectively treated. In this paper I review the etiologic background, the characteristics of depressive mood disorders and the most important steps of making diagnosis, as well as the state of the art therapeutic options. Rapid recognition and effective treatment of depressive symptoms has important therapeutic and preventive significance, so today, besides psychiatrists, there is an increasing role for general practitioners and other specialists (internists, neurologists, etc.).]

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.

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.

[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.

There were two sessions for both groups: the immediate testing phase and the delayed retesting phase, separated by 24 hours. Our results suggest that the timing of learning and sleep plays an important role in the stabilizing process of memory representation to resist against forgetting.]
