[THE DIFFERENTIATION OF CHRONIC PANCREATITIS FROM PANCREATIC CANCER]

CZAKÓ László

[The poor prognosis of pancreatic cancer is mainly due to late diagnosis. The differentiation between pancreatic cancer and chronic pancreatitis is difficult, because the two diseases cause similar clinical symptoms and morphological alterations. Furthermore, chronic pancreatitis is associated with an increased risk of malignant transformation, thus the two diseases may be present simultaneously. The recent developments in molecular genetic tests and in imaging techniques, such as multidetector computed tomography, magnetic resonance cholangio- pancreatography, endoscopic ultrasoundguided fine needle aspiration and positron emission tomography/computed tomography, have fundamentally transformed the differentiation of the two disorders. This paper provides a systematic review of the recent evidence-based results concerning the differentiation of pancreatic cancer and chronic pancreatitis.]

[EFFECT OF END-OF-LIFE EDUCATION ON MEDICAL STUDENTS’ AND HEALTH CARE WORKERS’ DEATH ATTITUDE]

HEGEDÛS Katalin, ZANA Ágnes, SZABÓ Gábor

[INTRODUCTION - The aim of our research was to evaluate the effect of courses for health care workers and medical students that deal with death, dying and bereavement and that of courses on hospice care of dying patients. The goal of the courses is to make communication on death more open by exploring critical issues related to fear of death to reduce inner anxiety and to improve attitude to dying patients. PARTICIPANTS AND METHOD - Participants (n=168) completed Neimeyer and Moore's Multi-dimensional Fear of Death Scale (MFODS) and Shortened Beck Depression Questionnaire (BDI) on the first and last day of the courses. In case of health care workers a follow-up survey was also performed 2 to 3 months after the course (n=32). RESULTS - The most significant factors of fear of death are: fear for significant others, fear of the dying process and fear of premature death. Overall fear of death scores are reduced as an effect of the courses, the alteration of the components of fear of death depends on the participants’ gender, age and profession as well. Improvement was observed in both groups in attitudes that can be related to the increase of knowledge on the quality care of dying patients like fear from the process of dying and fear from conscious experience of death. CONCLUSION - Besides education containing training as well it is important to strengthen the support function of workplaces in caring for the mental health of the health care staff. Furthermore it is important during gradual education that students participate in courses that aim to achieve opened communication in the most anxiety-evoking issues.]

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.

[Background – Spinal muscular atrophy (SMA) is an autosomal recessive, progressive neuromuscular disorder resulting in a loss of lower motoneurons. Recently, new disease-modifying treatments (two drugs for splicing modification of SMN2 and one for SMN1 gene replacement) have become available. Purpose – The new drugs change the progression of SMA with neonatal and childhood onset. Increasing amount of data are available about the effects of these drugs in adult patients with SMA. In this article, we summarize the available data of new SMA therapies in adult patients. Methods – Members of the Executive Committee of the Hungarian Clinical Neurogenetic Society surveyed the literature for palliative treatments, randomized controlled trials, and retrospective and prospective studies using disease modifying therapies in adult patients with SMA. Patients – We evaluated the outcomes of studies focused on treatments of adult patients mainly with SMA II and III. In this paper, we present our consensus statement in nine points covering palliative care, technical, medical and safety considerations, patient selection, and long-term monitoring of adult patients with SMA. This consensus statement aims to support the most efficient management of adult patients with SMA, and provides information about treatment efficacy and safety to be considered during personalized therapy. It also highlights open questions needed to be answered in future. Using this recommendation in clinical practice can result in optimization of therapy.]

Risk factors related to intracranial infections after transsphenoidal pituitary adenomectomy under endoscope

XU Yifan, HE Yuxin , XU Wu, LU Tianyu, LIANG Weibang, JIN Wei

Background – Up to now, the risk factors related to intracranial infections after transsphenoidal pituitary adenomectomy remain controversial. Purpose – To analyze the risk factors related to intracranial infections after transsphenoidal pituitary adenomectomy under an endoscope, and to provide evidence for preventing and controlling the occurrence and development of infections. A total of 370 patients receiving endoscopic transsphenoidal pituitary adenomectomy in our hospital from January 2014 to October 2017 were selected. The risk factors related to postoperative intracranial infections were analyzed. The hospitalization lengths and expenditures of patients with and without intracranial infections were compared. Of the 370 patients, 18 underwent postoperative intracranial infections, with the infection rate of 4.86%. Intraoperative blood loss >120 mL, cerebrospinal leakage, diabetes, preoperative use of hormones, macroadenoma as well as surgical time >4 h all significantly increased the infection rate (P<0.05). Preoperative use of antibacterial agents prevented intracranial infection. Compared with patients without intracranial infections, the infected ones had significantly prolonged hospitalization length and increased expenditure (P<0.05). Discussion – It is of great clinical significance to analyze the risk factors related to intracranial infection after endoscopic transsphenoidal pituitary adenomectomy, aiming to prevent and to control the onset and progression of infection. Intracranial infections after endoscopic transsphenoidal pituitary adenomectomy were affected by many risk factors, also influencing the prognosis of patients and the economic burden.

A rare entity of acquired idiopathic generalised anhidrosis which has been successfully treated with pulse steroid therapy: Does the histopathology predict the treatment response?

ÖKTEM Özdemir Ece, ÇANKAYA Şeyda, UYKUR Burak Abdullah, ERDEM Simsek Nazan, YULUG Burak

Acquired idiopathic generalised anhidrosis is an uncommon sweating disorder characterized by loss of sweating in the absence of any neurologic, metabolic or sweat gland abnormalities. Although some possible immunological and structural mechanisms have been proposed for this rare entity, the definitive pathophysiology is still un­clear. Despite some successfully treated cases with systemic corticosteroid application, the dose and route of steroid application are controversial. Here, we present a 41-year-old man with lack of genera­lised sweating who has been successfully treated with high dose pulse intravenous prednisolone. We have discussed his clinical and histopathological findings as well as the treatment options in view of the current literature.

[Current questions of multiple sclerosis: the secunder progressive form of the disease]

VÉCSEI László

[Recent data suggest that long-term worsening is common in relapsing-remitting multiple sclerosis patients and is largely independent of relapses or new lesion formation on brain MRI. The current definition of secunder progressive multiple sclerosis is worsening of disability independent of relapses over at least 6-month interval. Early focal inflammatory disease activity and spinal cord lesion are predictors of very-long term disease outcomes in relapse - onset multiple sclerosis. The potential of PET imaging to visualize hidden inflammation in MS brain in vivo is an important contribution for better understanding the progression of the disease. Therefore, PET imaging is a promising tool in detecting the conversion from relapsing remitting multiple sclerosis to secunder progressive form of multiple sclerosis. Furthermore, neuro-axonal damage is the pathological substrate of permanent disability in different neurological disorders including multiple sclerosis. The neurofilament proteins have promise in this context because their levels rise upon neuro-axonal damage not only in the cerebrospinal fluid but also in blood. Patients with increased serum levels of neurofilament at baseline, independent of other clinical and MRI variables, experience significantly more brain and spinal cord volume loss over 2 years and 5 years of follow-up. The kynurenine-pathway abnormalities may be associated with the swich from early-mild stage multiple sclerosis to debilitating progressive forms of the disease. Analysis of these metabolites in serum may have application as multiple sclerosis disease biomarkers. Free radical action has been suggested as a causal factor in the illness. Increased free radical production and consumption of the scavenger molecules were found during the active phase of the disease. Based on the clinical findings (EXPAND Study) and pathomechanism of the disease siponimod is approved by the US Food and Drug Administration for the treatment of relapsing remitting forms of multiple sclerosis, to include secunder progressive multiple sclerosis with active disease, relapsing-remitting multiple sclerosis and clinically isolated syndrome.]
