[The real cost of caring for seriously ill patients - compassion fatigue or satisfaction]

KEGYE Adrienne, ZANA Ágnes, RÉVAY Edit, HEGEDÛS Katalin

[The improvement of the Hungarian hospice network and the increasing number of people dealing with the seriously ill are reflected by the annual hospice reports (2001-2013). However these reports also draw the attention to the cumulating mental and spiritual burdens of carers which can lead to fatigue and burnout. On the base of practical experience we surveyed the mental and spiritual condition of the caregivers of seriously ill patients and also reviewed research findings and the professional literature on the exposure to imperilment. The grounds of professional literature’s research were the Hungarian and international databases. We favoured studies published in Hungarian or English between 2000 and 2014 primarily on carers working in palliative and hospice service. One of the main profits of reviewing the professional literature is getting more detailed information on the mental state of professional caregivers. Relatively new element in researches is studying the relation between burnout and compassion satisfaction and compassion fatigue. It includes studying of symptoms and coping strategies. These all enable a better understanding of causes and help us to support hospice carers with more effective methods to protect them from mental and spiritual exhaustion.]

[Biosimilar insulins on the horizon]

JERMENDY György, KERPEL-FRONIUS Sándor

[Nowadays human insulins and insulin analogues are exclusively used in the clinical practice, when insulin therapy is needed. The patents of human insulins are expired and will expire soon for glargine, the first long-acting, basal insulin analogue preparation. The reliable production of biosimilar insulins is a new challenge for the pharmaceutical industry. Independently developed insulins with appreciable clinical efficacy have already become available in some countries where the quality criteria of regulatory process in place are less strict than in the European Union. The first approval for true biosimilar insulin, i.e. for biosimilar glargine was given in Europe in 2014. In this article, the characteristics of biosimilar insulins, especially the difficulties in the manufacturing process are reviewed in comparison with generic drugs. It is of note that potential efficacy and safety differences may occur due to even minor changes in the production, formulation and storage of the biological drugs. Therefore, biosimilarity should be investigated by detailed comparative pharmacokinetic and pharmacodynamic studies. Moreover, similar clinical efficacy and safety should be documented by randomized, comparative clinical trials. The potential impact of altered immunologic profile of biosimilar insulins should also be carefully monitored. ]

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.

[Vinpocetin in neurological diseases]

[Introduction - Stroke is the third leading cause of death worldwide (following cardiovascular and cancer mortality) and associated with serious disability for the vast majority of patients. There is no salvage therapy for irreversibly damaged brain areas, improving the circulation of the surrounding hypoperfused territories may be associated with benefitial clinical states. Cerebral hypoperfusion may play a role in the pathogenesis of other kind of neurological diseases, improvement of global circulation may have a preventive effect on these conditions. Aims - The aim of our study was to review the experimental and clinical articles focusing on the role of vinpocetin in different neurological conditions. Results - Vinpocetin appears to have several different mechanisms of action that allow for its antiinflammatory, antioxidant, vasodilating, antiepileptic and neuroprotective activities in experimental conditions. On the other hand, several meta-analysis of the existing studies in acute stroke examining short and long term fatality rates with vinpocetin was unable to assess efficacy. In chronic cerebrovascular patients, vinpocetin improves impaired hemorheological variables, has significant vasodilating properties, improves endothelial dysfunction, neuroimaging studies showed selective increase in cerebral blood flow and cerebral metabolic rate, all of which are potentially beneficial in cerebrovascular disease and may improve cognitive functions. Summary - Based on the above mentioned results vinpocetin plays an important role both in basic research and in clinical management of different neurological diseases.]

[TREATMENT OF GASTROESOPHAGEAL REFLUX DISEASE]

PAPP János

[In the acidic type of gastroesophageal reflux disease treatment is based on the use of proton pump inhibitors. Efficiency of the treatment is primarily assessed by the changes in symptoms. A long-term, continuous drug use is invariably necessary. In typical cases an increased dose or combination therapy is rarely required, however, in the presence of extraesophageal symptoms, the use of higher doses has been found to be beneficial. The minimum efficient drug amount is usually determined by gradually decreasing the dose. Surgery is mainly recommended for young patients, but it is indispensable in the management of complications or in volume reflux. Endoscopic antireflux therapy is still considered a clinical trial. Treatment of Barrett’s oesophagus by drugs or antireflux surgery does not decrease the incidence of Barrett’s cancer - the mostly recommended approach is endoscopic ablation.]

[Effect of zoledronic acid treatment on pain and quality of life in patients with metastatic bone disease suffering from breast and prostate cancer - Multicenter, prospective, observational study]

PÁPAI Zsuzsanna, LANDHERR László, SPEER Gábor

[INTRODUCTION - Metastatic bone disease is frequently associated with breast and prostate cancer. Bisphosphonate treatment of bone metastases is palliative: its primary goal is to relieve pain, while it's also important to decrease the risk of bone fractures, prolong survival and maintain physical activity of the patients. Pain is the most common symptom of bone metastases. PATIENTS AND METHODS - In total 845 patients were enrolled in our open, multicenter, prospective, observational study, the first of its kind in Hungary. The agent tested was zoledronic acid (Zometa®). Duration of the study was 20 months and its primary goal was to assess the correlation between pain and quality of life during the treatment of patients with bone metastases from breast or prostate carcinoma. RESULTS - During the 18 months of the study, the average intensity of pain, measured on the visual analog scale showed a 42% reduction (p<0.0001). By the end of the 18. month, the ratio of patients free of symptoms has increased by 15% and the number of patients with substantial complaints has decreased by 73%. CONCLUSION - Our study supports the observation published in the international literature that in patients with bone metastases from breast and prostate cancer, zoledronic acid treatment is beneficial for reducing pain and thus for improving quality of life.]
