[AUTOIMMUNE PANCREATITIS - AN UNDERDIAGNOSED DISEASE?]

CZAKÓ László

[Autoimmune pancreatitis is a recently recognized type of chronic pancreatitis that is clearly distinct from alcoholic chronic pancreatitis. Its clinical symptoms include jaundice, abdominal pain, weight loss and diabetes mellitus. It may be associated with other autoimmune diseases. IgG levels are elevated and autoantibodies can be detected. Pancreatic imaging reveals a diffuse enlargement of the pancreas and irregular narrowing of the main pancreatic duct. The characteristic histological features are lymphoplasmacytic infiltration and fibrosis. Autoimmune pancreatitis responds dramatically to steroid therapy, in contrast to other types of chronic pancreatitis, which hardly respond to any of the various therapies. It is important to be aware of this disease because it may be mistaken for other forms of chronic pancreatitis or pancreatic cancer, which leads to pancreatic resection when steroid treatment would be sufficient. This review discusses the clinical, laboratory, histological and imaging findings that are seen in autoimmune pancreatitis with particular focus on diagnosis. With the improvement of the diagnostic work-up less unnecessary pancreatic resections are expected to happen in patients with autoimmune pancreatitis.]

[ENDOTHELIAL DYSFUNCTION IN DYSLIPIDAEMIA - THE ROLE OF THE RENIN-ANGIOTENSIN SYSTEM]

FARKAS Katalin

[Dyslipidaemia is one of the known main risk factors of atherosclerosis by causing endothelial dysfunction that initiates and promotes vascular remodelling. Recent data from experimental and clinical studies suggest the existence of lipoprotein- neurohormonal interactions that may adversely affect vascular structure and function. Elevated lipid levels enhance the activation of the renin-angiotensin system, and, on the other hand, activation of the renin-angiotensin system leads to increased LDL cholesterol biosynthesis and oxidized-LDL uptake. These findings may explain the synergistic effect on cardiovascular risk observed in patients with coexisting hypertension and dyslipidaemia. The combined use of cholesterol-lowering drugs and inhibition of the tissue renin-angiotensin system may be more efficient in reducing cardiovascular risk.]

[FUTURE CARRIER AND FAMILY PLANS OF 5TH-YEAR FEMALE MEDICAL STUDENTS]

FEITH Helga Judit, KOVÁCSNÉ Tóth Ágnes, BALÁZS Péter

[INTRODUCTION - The aim of this study was to analyze female medical students' carrier and family attitudes and plans in view of two social problems: (1) the increasing shortage of physicians in Hungary and (2) conflicts and health problems in the life of female doctors caused by professional and family duties. METHOD - The basis of this study is a selfreported questionnaire-based survey performed in the spring of 2004 among 5th-year female medical students in the faculties of general medicine at Semmelweis and Debrecen universities. One hundred and seventeen students (46.2%) responded. RESULTS - The overwhelming majority of students (91.5%) want to work as a physicians, and 63.5% plan to work abroad in health care. As to family planning, 95.7% of the respondents would like to have children, although only 52.8% plan to stay at home in the first three years. CONCLUSION - These data suggest that the majority of Hungarian female medical students want to be engaged in the medical profession and plan to meet both family and career demands. Due to its special requirements, however, this profession may generate future marital, childmother relationship and workplace conflicts.]

GYÖKERES Tibor, KIRÁLY Ágnes, LAKATOS László, MADÁCSY László

[This paper reviews the current knowledge on the association of obesity and gastrointestinal disorders. While the relationship between obesity and cardiovascular disorders has recently gained wide professional publicity, there are few data on the gastroenterological aspects of obesity. After a discussion on obesity as an epidemic, its international and national prevalence, and public health risks, the most common obesity-related gastrointestinal disorders, their incidence, pathomechanism and consequences are presented by the organ systems affected, including gastrooesophageal reflux disease, fatty liver, gallstone disease, diseases of the pancreas, and colorectal carcinoma. Finally, the means of prevention and treatment are summarized.]

Cases of inborn errors of metabolism diagnosed in children with autism

CAKAR Emel Nafiye, YILMAZBAS Pınar

Autism spectrum disorder is a neurodevelopmental disorder with a heterogeneous presentation, the etiology of which is not clearly elucidated. In recent years, comorbidity has become more evident with the increase in the frequency of autism and diagnostic possibilities of inborn errors of metabolism. One hundred and seventy-nine patients with diagnosis of autism spectrum disorder who presented to the Pediatric Metabolism outpatient clinic between 01/September/2018-29/February/2020 constituted the study population. The personal information, routine and specific metabolic tests of the patients were analyzed retrospectively. Out of the 3261 patients who presented to our outpatient clinic, 179 (5.48%) were diagnosed with autism spectrum disorder and were included in the study. As a result of specific metabolic examinations performed, 6 (3.3%) patients were diagnosed with inborn errors of metabolism. Two of our patients were diagnosed with classical phenylketonuria, two with classical homocystinuria, one with mucopolysaccharidosis type 3D (Sanfilippo syndrome) and one with 3-methylchrotonyl Co-A carboxylase deficiency. Inborn errors of metabolism may rarely present with autism spectrum disorder symptoms. Careful evaluation of the history, physical examination and additional findings in patients diagnosed with autism spectrum disorder will guide the clinician in the decision-making process and chose the appropriate specific metabolic investigation. An underlying inborn errors of metabolism may be a treatable cause of autism.

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

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.

[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.

Evaluation of the effectiveness of transforaminal epidural steroid injection in far lateral lumbar disc herniations

EVRAN Sevket, KATAR Salim

Far lateral lumbar disc herniations (FLDH) consist approximately 0.7-12% of all lumbar disc herniations. Compared to the more common central and paramedian lumbar disc herniations, they cause more severe and persistent radicular pain due to direct compression of the nerve root and dorsal root ganglion. In patients who do not respond to conservative treatments such as medical treatment and physical therapy, and have not developed neurological deficits, it is difficult to decide on surgical treatment because of the nerve root damage and spinal instability risk due to disruption of facet joint integrity. In this study, we aimed to evaluate the effect of transforaminal epidural steroid injection (TFESI) on the improvement of both pain control and functional capacity in patients with FLDH. A total of 37 patients who had radicular pain caused by far lateral disc herniation which is visible in their lumbar magnetic resonance imaging (MRI) scan, had no neurological deficit and did not respond to conservative treatment, were included the study. TFESI was applied to patients by preganglionic approach. Pre-treatment Visual Analogue Scale (VAS) and Oswestry Disability Index (ODI) scores of the patients were compared with the 3rd week, 3rd month and 6th month scores after the procedure. The mean initial VAS score was 8.63 ± 0.55, while it was 3.84 ± 1.66, 5.09 ± 0.85, 4.56 ± 1.66 at the 3rd week, 3rd month and 6th month controls, respectively. This decrease in the VAS score was found statistically significant (p = 0.001). ODI score with baseline mean value of 52.38 ± 6.84 was found to be 18.56 ± 4.95 at the 3rd week, 37.41 ± 14.1 at the 3rd month and 34.88 ± 14.33 at the 6th month. This downtrend of pa­tient’s ODI scores was found statistically significant (p = 0.001). This study has demonstrated that TFESI is an effective method for gaining increased functional capacity and pain control in the treatment of patients who are not suitable for surgical treatment with radicular complaints due to far lateral lumbar disc hernia.
