[SARS-CoV-2 virus attacks nőt only the lungs bút alsó many other or- gans (heart, kidney, liver, pancreas, gastrointestinal tract, brain, hematopoiesis) and regulatory system (RAAS, immuné system) to different degrees and with dif- ferent pathomechanisms. Accordingly, cell death, tissue damage and dysfunction or failure of somé organs has been developed. Our paper provides a detailed analysis of the incidence of extrapulmonary lesions, clinical manifestations, and the underlying pathomechanisms. This multi-organ damages was detected dom- inantly in severe Covid cases, bút may occur in moderate or mild cases. It should alsó be taken intő account that the consequences may occur after the acute phase, in a seronegative State - months after the onset of infection. In particu- lar, the heart (myocarditis, coronary insufficiency, arrhythmia), the kidney (acute renal failure and then permanent GFR decrease), glucose metabolism disorder (diabetes worsening, ketoacidosis, new diabetes) are the biggest therapeutic challenge. Multi-organ damage is due to direct virus-induced cell death, endo- thelial cell damage in the vascular system, and thrombo-inflammation with the formation of microthrombi, imbalance in the RAAS regulatory system, and early and delayed abnormal immuné response (cytokine storm).]

[Data on blood pressure over two years in resistant hypertensive patients with lett brain stem microvascular decompression]


[In the background of resistant hypertension (RHT) the neurovascular pulsatile compression (NVPC) of the left rostral ventrolateral medulla may play a role. In these cases a microvascular decompression (MVD) may decrease the blood pressure (BP). The aim of this work was to investigate how the BP has changed after the MVD in the operated patients recorded at the farthest time from the MVD up to maximum 31 December 2016. We have retrospectively collected data from 9 patients whose follow-up data fór 2 years has already been published earlier. Data collection was carried out from the patient register program of the University of Szeged Albert-Szent Györgyi Clinical Centre. The MVDs were performed between 2000 and 2004. The mean follow-up time was 11.1±4.6 years. Both the systolic and the diastolic BPs were significantly lower at the time of last record compared to the BPs at the time of MVD (systolic BP 211±40 vs. 135±20 mmHg, p=0.003; diastolic BP 116±17 vs. 81±14 mmHg, p=0.007). Last recorded BPs compared to the 24-month data alsó were lower bút nőt signffi- cantly (systolic BP 148±32 vs. 135±20 mmHg, p=0.25; diastolic BP 96 vs. 85 mmHg, p=0.11). The mean number of antihypertensives at the last Office visít was nőt sig- nificantly higher compared to MVD (5.9±1.4 vs. 6.3±1.5; p=0.5) bút signfficantly increased compared to MVD +1 month data (4.7±0.9vs. 6.3±1.5; p=0.03). These results confirmed our previous opinion that in severe RHT nőt respond- ing to conventional therapy an MVD of the left side NVPC could be a therapeutic option and may guarantee a long-lasting BP reduction. Evén if the number of antihypertensives increased in the meantime, as they still responded better to therapy. ]

[Nonproteinuric diabetic kidney disease]


[Diabetic nephropathy is one of the most common causes of chronic kidney disease. In recent years, besides the classic phenotype with increased urinary albumin excretion, another phenotype showing Progressive kidney failure without albuminuria has been observed with increasing frequency. The histology, the pathophysiology and the course of non-proteinuric diabetic kidney disease differs from the classic phenotype in several respects. The former shows traits similar to atherosclerotic kidney disease with respect to association with cardiovascular disease and histological alterations and the progression is slower. This has important implications concerning the screening, treatment and prognosis of the disease. While the available data about non-proteinuric diabetic nephropathy is relatively scant, it deserves attention both in everyday clinical practice and in scientific research.]

[Risk of drug-drug interactions in hemodialyzed patien]

SZABÓ Alexandra, HARIS Ágnes

[Hemodialysis patients usually need large number of medications fór treatment of their multiple comorbidities. Because of the polypharmacy we have to count on several drug-drug interactions, which might necessitate modification of types and dosages of drugs, based on the patient's actual condition and current treatment. The use of anticoagulants causes everyday problems, because these drugs have high pharmacokinetics potency, and on the other hand their administration is indispensable. In our investigation we aimed to analyze the drug therapy of chronic hemodialysis patients in the Szent Margit Hospital Taraba István Dialysis Unit, and present the clinical pharmacist's role in the hospital team.]

[Changes in systolic blood pressure in the Hungárián aduit population between 2010 and 2018 based on public health screening data]


[Using our mobile public health screening system, we examined the changes in systolic blood pressure averages and systolic pressure distribution between 2010 and 2018 by analyzing the data of 72,857 women (mean age 42.3±13.9 years) and 61,563 mén (mean age 42.2±13.9 years) in three consecutive time periods. The SBP averages have been gradually and significantly decreased since 2010 in all age groups. The parametric and non-parametric characteristics of the systolic distribution curves alsó showed a favorable change during the indicated period. The observed changes may indicate that the primary and secondary prevention, as well as the treatment of hypertension and the physician-patient cooperation in Hungarywere successful in the indicated period.]

[Correlations Between Burnout and Socio-demographic and Workplace Related Factors Among Health-care Workers During The Covid-19 Pandemics]


[The present study aimed to assess the level of burn-out among health-care workers in 2020 and its correlations with socio-demographic and workplace related factors. The cross-sectional study was conducted by the means of a self-constructed online survey in the beginning of 2021. The responses of 1965 people were analysed with the help of SPSS 23.0. Descriptive statistics, chi-square and Kruskal-Wallis probes were run (p<0.05). Severe burnout was present in 46.7% of the responders. Age, marital status, type of health-care provided and years spent in the health-care system didn’t show any correlation with burnout. Unsure vision, opinion about salary raise and uncertainty at the workplace influenced the level of burnout significantly (p<0.000). The mental health of health-care workers is in continuous decline, in which the COVID-19 pandemic might play a big role. People with worse mental health feel more uncertain regarding their future and job; this might make providing health-care more and more difficult.]

Vaccines against the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) have been rapidly developed to prevent coronavirus disease 2019 (COVID-19) pandemic. There is increasing safety concerns regarding COVID-19 vaccines. We report a 78-year old woman who was presented with tetraparesis, paresthesias of bilateral upper extremities, and urinary retention of one-day duration. Three weeks before these symptoms, she was vaccinated with CoronaVAC vaccine (Sinovac Life Sciences, China). Spine magnetic resonance imaging showed longitudinally extensive transverse myelitis (TM) from the C1 to the T3 spinal cord segment. An extensive diagnostic workup was performed to exclude other possible causes of TM. We suggest that longitudinally extensive TM may be associated with COVID-19 vaccination in this case. To the best of our knowledge, this is the first report of longitudinally extensive TM developing after CoronaVac vaccination. Clinicians should be aware of neurological symptoms after vaccination of COVID-19.

The effect of sniffing Turkish coffee on olfactory disorders in COVID-19 patients: An experimental clinical study


The current study aimed to examine the effect of sniffing Turkish coffee on the sense of smell in COVID-19 patients. This study utilized the experiment-control method. Data were collected using a patient and disease information form and the Connecticut Chemosensory Clinical Research Center (CCCRC) Test. An experimental group of patients sniffed Turkish coffee, and the coffee’s effect on the patients’ sense of smell was examined. All data were analyzed using SPSS version 25 (IBM). Of the patients in the experimental group, 25% had moderate hyposmia, 58.3% had severe hyposmia, and 16.7% had anosmia prior to sniffing Turkish coffee. After sniffing the Turkish coffee, 13.3% of these patients regained their ability to smell normally, while 18.3% had mild hyposmia, 45% had moderate hyposmia, 6.7% had severe hyposmia, and 16.7% had anosmia. There was no difference in the control group between first and second measurement. COVID-19 patients who sniffed Turkish coffee intermittently regained some of their sense of smell for one hour. Turkish coffee is cheap, fragrant, widely available, and easy to access. Therefore, results of this study suggest that it may be recommended for treating olfactory disorder in COVID-19 patients.

The effect of starting a meal with salt and date palm on taste impairment caused by COVID-19


This study was conducted to examine the effect of starting a meal with salt and date palm on the sense of taste in COVID-19 patients. This study was conducted using a randomized controlled method. Patient and disease information forms and Visual Analog Scale were used for data collection. Salt and date palm were used to stimulate the sense of taste in two different experimental groups. No procedure was made in the control group except for the practice of the clinic. The results were analyzed using SPSS version 25. The mean ages of all groups were between 43.42 ± 8.60 and 47.22 ± 12.04 years. Fever, sore throat, dry mouth, cough, muscle weakness, and similar symptoms were present in all groups. Significant improvements were found in patients with hypoageusia and ageusia after date palm and salt application (p<0.01). For taste impairment caused by COVID-19, consumption of date palm and tasting very little salt for therapeutic purposes may help to alleviate taste impairment. Based on the data obtained from this study, the pathophysiology of the effects of date palm and salt on taste complications should be investigated.
