[Stroke incidence and prevalence in the world]

KÉKES Ede

[The incidence and prevalence of ischaemic and haemorrhagic stroke declined continuously from 1970 to 2010. The rate of incidence was the lowest in North America, within Europe in the Mediterranean countries, France and in Asian developed countries. The incidence and prevalence the progress of age have in - creased respectively. The outcome of haemorrhagic stroke is worse everywhere, than that of ischaemic form, rate of mortality/incidence is greater.]

[The importance and techniques of fluid status assessment in patients with heart and kidney disease]

LEDÓ Nóra, HORVÁTH Viktor József, TISLÉR András

[Managing the fluid balance in patients with chronic heart and kidney disease is critical, it exceptionally affects the success of the therapy. Therefore, it is crucial to recognize and treat the fluid overload or depletion as soon as possible. Plenty of methods are available to assess fluid status, which can help us to find the right diagnosis, plan and follow the therapy of the patients. The aim of our review article is to present the current techniques of estimating fluid status. Beside the widely used methods (e.g. physical examination, laboratory testing) we describe other techniques which are less common in the Hungarian clinical practice but easy to use, such as chest sonography and bioimpedance spectroscopy. To choose the right approach for assessing fluid status, we have to examine the advantages and disadvantages of the methods in consideration of the patient’s individual needs.]

[Effects of ketodiet in fourth-stage chronic renal failure]

KÓSA Dezider, GELENCSÉR Éva, PALOTAI Ágota, GASZTONYI Beáta

[The well-known progressive nature of chronic renal failure can be slowed by low protein diet of various degrees. We applied standard 0.6g/kg body weight diet with supplement of essential amino acids and keto acids, 1 tablet/10 kg body weight Ketosteril was administered to 100 patient with IV. stage chronic renal failure for 31.5 months in average (10-63 month). During observational period 11% of the patients started hemodialysis program, 4 patients died. At the end of the observational period on basis of laboratory value of renal function 31% of patients had III, 50% IV, 19% V. stage chronic renal failure. We applied calculated glomerular filtration rate (ml/min/1.73 m2) for following the renal function. Average GFR value reduced from 24.9 to 23.63 ml/min/1.73 m2 (not significant). In case of female patients, we found a milder loss in renal function, average GFR was reduced from 24.8 to 24.6 ml/min/1.73 m2. We observed that women hold on the prescribed diet in greater ratio. On basis of the BMI value calculated at end of our examination no patient was undernourished. 25.8% of the patients had normal body weight, 54.3% had overweight, 17.5% was obese and 2.4% severely obese. We followed the changes in state of nourishment by serum albumin value, average serum albumin was 42.92 g/l at beginning and did not change significantly (42.81 g/l at the end of our examination). Applying keto diet is safe and efficient in slowing the progression of severe chronic renal failure and improves the state of nourishment. Good state of nourishment achieved in predialytic stage is associated with low mortality ratio and gives opportunity to lower the mortality of patients starting dialysis program.]

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.
