[Nutritional status of hemodialysis patients, and the role of dietician in the complex care of renal patients]

POLNER Kálmán, KOVÁCS Lívia, HARIS Ágnes

[In chronic renal failure severe cardiovascular complications develop, which are the cause of death in 50% of the patients. According to recent results, behind the accelerated atherosclerosis, malnutrition and inflammation, developing in patients with chronic renal failure, play significant role. Malnutrition and inflammation show close relationship to the serum albumin level, which is an independent predictor of mortality. Authors studied the nutritional parameters of 94 chronically hemodialysis patients. Patients had been dialysed for more than three months, for 3×4-4.5 hours weekly. Among them 36% had diabetes. According to BMI (body mass index) 42.5% of the patients was normally nourished (20-24 kg/m2), 11.7% of them had malnutrition, 28.7% was overweight, and 17.1% was mildly or moderately obese. Subjective Global Assessment (SGA), calculated by dietician, revealed, that 47.9% of the patients has normal nutritional condition, all the others had some degree of malnutrition. Serum albumin level showed close correlation with the nutritional status, also with an inflammatory marker, the CRP. Only 63.8% of the patients had higher than 40g/l serum albumin. Those, who had higher than 10 mg/l CRP value, had significantly lower serum albumin (38.7±3.4 g/l), comparing to the albumin of the patients, whose CRP was below 10 mg/l (40.5±3.9 g/l, p=0.04). Comparing anthropometrical data, there was no significant difference between diabetic and non-diabetic patients. Grouping patients by their ages, the malnutrition, defined by SGA scores and by serum albumin level, was significantly worse in patients older than 80 years, than in the younger than 50 years old subjects, which signals increased risk of mortality of the elderly patients. A case presentation demonstrates, that malnutrition can be diagnosed at early stage by appropriate nutritional assessment, and it can be corrected by timely and satisfactory energy- and nutrient-substitution, in severe cases by specially prepared nutritional supplements, and thereby the patient’s severe cardiovascular risk can be ameliorated. The successful treatment of hemodialysis patients requires change in medical practice, and close cooperation between physicians and dieticians.]

[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 majority of patients with advanced Parkinson’s disease are treated at specialized movement disorder centers. Currently, there is no clear consensus on how to define the stages of Parkinson’s disease; the proportion of Parkinson’s patients with advanced Parkinson’s disease, the referral process, and the clinical features used to characterize advanced Parkinson’s disease are not well delineated. The primary objective of this observational study was to evaluate the proportion of Parkinson’s patients identified as advanced patients according to physician’s judgment in all participating movement disorder centers across the study. Here we evaluate the Hungarian subset of the participating patients. The study was conducted in a cross-sectional, non-interventional, multi-country, multi-center format in 18 countries. Data were collected during a single patient visit. Current Parkinson’s disease status was assessed with Unified Parkinson’s Disease Rating Scale (UPDRS) parts II, III, IV, and V (modified Hoehn and Yahr staging). Non-motor symptoms were assessed using the PD Non-motor Symptoms Scale (NMSS); quality of life was assessed with the PD 8-item Quality-of-Life Questionnaire (PDQ-8). Parkinson’s disease was classified as advanced versus non-advanced based on physician assessment and on questions developed by the Delphi method. Overall, 2627 patients with Parkinson’s disease from 126 sites were documented. In Hungary, 100 patients with Parkinson’s disease were documented in four movement disorder centers, and, according to the physician assessment, 50% of these patients had advanced Parkinson’s disease. Their mean scores showed significantly higher impairment in those with, versus without advanced Parkinson’s disease: UPDRS II (14.1 vs. 9.2), UPDRS IV Q32 (1.1 vs. 0.0) and Q39 (1.1 vs. 0.5), UPDRS V (2.8 vs. 2.0) and PDQ-8 (29.1 vs. 18.9). Physicians in Hungarian movement disorder centers assessed that half of the Parkinson’s patients had advanced disease, with worse motor and non-motor symptom severity and worse QoL than those without advanced Parkinson’s disease. Despite being classified as eligible for invasive/device-aided treatment, that treatment had not been initiated in 25% of these patients.]

[Thiazide- or thiazide-like diuretics should be used in the treatment of patients with hypertension? Particularities of the situation in Hungary]


[Diuretics have remained the cornerstone of the antihypertensive treatment since their widespreading in the 1960s. According to the 2018 ESC/ESH Guidelines for the management of arterial hypertension, in the absence of evidence from direct comparator trials and recognizing that many of the approved single-pill combinations are based on hydrochlorothiazide, this drug and thiazide-like indapamide can be considered suitable antihypertensive agents. In the 2018 Hungarian guidelines indapamide is named as the most efficacious diuretic in the treatment of patients with hypertension. The aim of the publication is redefining thiazide- and thiazide-like diuretic use in the treatment of hypertensive patients, with particular attention to presently available hydrochlorothia­zide and indapamide, and their combination drugs in Hungary.]

[Complications of infusion treatment with emphasis on extravasation of cytostatics]

HARISI Revekka

[The extravasation of cytostatics is the most signifi cant complication of infusion therapy in cancer treatment. Extravasation refers to the inadvertent infi ltration of cytostatic drugs into subcutaneous or subdermal tissues surrounding the intravenous or intraarterial administration site. According to literature data incidence estimates between 0,01-7%. Extravasated drugs are classifi ed according to their potential for causing damage as vesicant, irritant and nonvesicant. Knowledge of risk factors, the patientrelated and treatment-related ones is important to minimize the occurrence of extravasation. In order to reduce the risk of extravasation, the staff involved in the tumor infusion therapy must be specially trained to implement several preventive and therapeutical protocols. In 2012, ESMO-EONS has put together a new comprehensive treatment protocol on the topic of cytostatics extravasation. Protocol recommended that every oncological department, who administers chemotherapy have to have extravasation trained team and a standby extravasation kit. According to the new ESMO-EONS guideline subcutaneous corticoids are not recommended, anymore. In case of mechloretamine extravasation the recommendation is immediate subcutaneous injection of sodium thiosulfate. After extravasation of anthracyclines, mitomycin C and platin salts the best treatment opportunity is subcutan dimethyl sulfoxide administration. In case of anthracyclines’ extravasation intravenous dexrazoxane treatment is also effective. Hyaluronidase, injected into or under the skin, facilitates absorption of extravasated drugs because of increases connective tissue permeability, promotes the spreading and reduces the local concentration of the extravasated citostatic agents. Hyaluronidase might be effi cacious in preventing skin necrosis by extravasation due to vinca alkaloids. The treatment of unresolved tissue necrosis or pain lasting more than 10 days is surgical debridement. Because of the medical and juristic importance of the extravasation event, it is necessary to establish uniform guidelines for treatment of extravasation, in all Hungarian Oncological Centers.]

[Decisional collisions between evidence and experience based medicine in care of people with epilepsy]


[Background – Based on the literature and his long-term clinical practice the author stresses the main collisions of evidence and experience based medicine in the care of people with epilepsy. Purpose – To see, what are the professional decisions of high responsibility in the epilepsy-care, in whose the relevant clinical research is still lacking or does not give a satisfactory basis. Methods – Following the structure of the Hungarian Guideline the author points the critical situations and decisions. He explains also the causes of the dilemmas: the lack or uncertainty of evidences or the difficulty of scientific investigation of the situation. Results – There are some priorities of experience based medicine in the following areas: definition of epilepsy, classification of seizures, etiology – including genetic background –, role of precipitating and provoking factors. These are able to influence the complex diagnosis. In the pharmacotherapy the choice of the first drug and the optimal algorithm as well as the tasks during the care are also depends on personal experiences sometimes contradictory to the official recommendations. Same can occur in the choice of the non-pharmacological treatments and rehabilitation. Discussion and conclusion – Personal professional experiences (and interests of patients) must be obligatory accessories of evidence based attitude, but for achieving the optimal results, in some situations they replace the official recommendations. Therefore it is very important that the problematic patients do meet experts having necessary experiences and also professional responsibility to help in these decisions. ]
