[NEW DISORDERS OF EATING AND OF BODY IMAGE]

TÚRY Ferenc, LUKÁCS Liza, RÁCZ Olimpia, HORVÁTH Krisztina

[Eating disorders show an important change in the last few decades concerning their frequency and clinical picture, as well. Besides bulimia nervosa, which was described two decades ago, muscle dysmorphia appeared ten years ago as a special body image disorder of males, regarded as a reverse form of anorexia nervosa in females. Eating disorder, body builder type was described only in 2000, meaning an overconcern about the body composition and muscle mass, accompanied by strict dieting rules. Another type of these disorders was described also in 2000, the nontraditional gender role in women, which is a strong preference for male characteristics and activities, the person being comfortable with her sex, while there is no intersex condition. This overview discusses the proposed diagnostic criteria and the role of some sociocultural factors in these recent disorders.]

[EXERCISE-INDUCED BRONCHOCONSTRICTION]

VIZI Éva, CSOMA Zsuzsanna, HUSZÁR Éva

[Exercise-induced bronchoconstriction describes the transient narrowing of the airways occurring during and most often after vigorous exercise. The mechanism of exercise-induced bronchoconstriction remains elusive, although airway drying and cooling plays a prominent role. The severity of this reaction depends on the temperature and the water content of the inspired air, the type and concentration of air pollutants inspired and the intensity of the exercise. Diagnosis of exercise-induced bronchoconstriction should include baseline spirometry followed by an exercise challenge test. The exercise can be a free-running test or a laboratory based test using a cycle-ergometer or a treadmill. Pre- and post-exercise pulmonary function should be compared, 10%-15% postexercise fall in forced expiratory volume in 1 second (FEV1) is used as a diagnostic criteria (10% in laboratory test, 15% in free-running test). Heat loss, water loss, post exertional airway rewarming and the role of several mediators have been proposed as possible mechanisms responsible for the airway obstruction induced by exercise. Exercise-induced bronchoconstriction can be easily diagnosed and treated in the majority of patients. When properly treated, asthmatic individuals should be able to participate or compete in the majority of sports.]

[THE VALUE OF RENAL BIOPSY IN DIABETES]

NAGY Judit, DEGRELL Péter, EKNOYAN Garabed, WITTMANN István

[The relentless increase of patients with kidney failure requiring renal replacement therapy has been documented world-wide. Recently, diabetic renal diseases has become the major cause of end-stage renal disease in the United States and in western Europe and is forecasted to become the most frequent cause of end-stage renal disease in Hungary. The most common renal lesion in type 1 as well as in type 2 diabetes is diabetic nephropathy. However, in the last few years numerous studies have demonstrated that there is a difference between patients with type 1 and those with type 2 diabetes in the expression and frequency of their renal disease. In type 1 diabetes a histological examination should only be made when a patient has features atypical of diabetic nephropathy and the indications of renal biopsy are well known. At the same time there is no agreement on renal biopsy indications in type 2 diabetes. In this review, we will summarise the characteristic features of diabetic nephropathy and other kidney alterations in the diabetic patient. Furthermore, we will raise the question of the renal biopsy indications and the more extensive use of the renal biopsy in type 2 diabetic patients for more effective prevention and treatment strategies.]

[CEREBRAL AMYLOID ANGIOPATHY - A FATAL CASE OF RECURRENT MULTIFOCAL CEREBRAL HEMORRHAGE]

POGÁNY Péter, HERMANN Zsuzsa

[Atherosclerosis and hypertension are the leading etiological factors in the pathogenesis of cerebral hemorrhage. With old age though, several other factors may appear of which cerebral amyloid angiopathy (CAA) is of major importance. This condition is characterized by the deposition of β-amyloid in the leptomeningeal vessels as well as in the small and medium sized arteries of the cerebral cortex and it is not associated with systemic amyloidosis. This pathological protein is also seen in the brains of otherwise healthy older individuals and may also appear in other diseases such as Alzheimer disease, Down-syndrome, vascular malformations, spongiform encephalopathy and dementia pugilistica. The condition may be asymptomatic but it may also cause cerebral hemorrhage, dementia or various transient neurological symptoms. Most cases are sporadic, but familial subtypes have also been described.]

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.

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. 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. 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.]
