Material and methods: The study was of prospective-retrospective character. It was carried out at the AKH in Vienna (Austria), where 100 patients with focal liver lesions were included in the study. All patients underwent the routine MR sequences on appliances 1,5 and 3T (Siemens, Germany): T1, T2, HASTE, VIBE, and a DWI with three b values (b 50, b 300 b 600 s / mm2) and ADC map with ROI (regions of interest). The numerical value of ADC map was calculated, where n = 100 liver lesions, by two independent radiologists. Results: On the basis of matching the PH finding statistically we get DWI accuracy of 96.8% for the assessment of liver lesions. The average numerical value of ADC in benign hepatic lesions (FNH, Hemangiomas) in our study amounted to 1.88 (1.326 to 2.48) x103 mm2 /s, while the value of malignant liver lesions (HCC, CCC, CRCLM) were significantly lower and amounted to 1.15 (1.024 to 1.343) x10-3 mm2 /s (Figure 2). Differences between the mean ADC of benign and malignant lesions showed a statistically significant difference with p <0.0005. In our research, we get cut-off for the ADC value of 1,341x10-3 mm2 /s, which proved to be the optimal parameter for differentiation between benign and malignant lesions. Conclusion: Measuring ADC values with DWI as an additional MRI tool can help in oncological practice by distinguishing normal liver parenchyma from focal lesions, and in differentiating benign from malignant liver lesions, particularly in cases where administration of contrast is not possible.

Desmoid tumor represents a rare monoclonal, fibroblastic proliferation characterized by a variable and often unpredictable clinical course. Although histologically benign, desmoids are locally invasive and associated with a high local recurrence rate, but lack of metastatic potential. Many issues regarding the optimal treatment of patients with desmoids remain controversial. Surgical resection and radiotherapy are standard treatment options for these patients. Due to heterogeneity of the biological behavior of desmoids, including long periods of stable disease or even spontaneous regression, treatment needs to be individualized to optimize local tumor control and preserve patient's quality of life. Therapeutic approaches to the treatment of recurrent or unresectable desmoid tumors comprise anti-hormonal therapy, non-steroidal anti-inflammatory drugs, classic chemotherapy regimens and tyrosine kinase inhibitor, with highly variable results. It has not yet been possible to establish an optimal therapy protocol for this disease. In this case report we present our experience with the treatment of recurrent extra-abdominal desmoid tumor.

Introduction: Positron emission tomography/computed tomography (PET-CT) is very sensitive for diagnosis of recurrent NSCLC and has a significant impact on change of management. Preliminary data suggest superiority of PET-CT comparing to CT alone for lung cancer restaging. Materials and methods: This is a retrospective study which aim is to validate usage of PET-CT in suspected non-small cell lung carcinoma recurrence and its impact on further patient management. Total number of 31 patients with non-small cell lung carcinoma and uncertain diagnosis of recurrent disease or its extent after routine clinical and CT work-up were enrolled in this study. Discussion: We found in our study that PET-CT diagnosed recurrent disease in 65% of patients who were previously presented with an indeterminante CT. In 85% of patients there were change in further management. Conclusion: We suggest that PET should be performed on patients who have suspected relapse after potentially curative treatment, particularly if active treatment is being considered. PET-CT improved the diagnosis of recurrent NSCLC and this resulted in a significant impact and change in further patient management.

Background: Methicillin resistant Staphylococcus aureus (MRSA) is responsible for a wide spectrum of nosocomial and community associated infections worldwide. The aim of this study was to analyze MRSA strains from the general population in Canton Sarajevo, B&H. Methods: Our investigation including either phenotypic and genotypic markers such as antimicrobial resistance, pulsed-field gel electrophoresis (PFGE), SCC typing, and Panton-Valentine leukocidin (PVL) detection. Results: Antimicrobial susceptibility: all MRSA isolates were resistant to the β-lactam antibiotics tested, and all isolates were susceptible trimethoprim sulphamethoxazole, rifampicin, fusidic acid, linezolid and vancomycin. Sixty-eight per cent of the MRSA isolates were resistant to erythromycin, 5% to clindamycin, 5% to gentamicin and 4% to ciprofloxacin. After the PFGE analysis, the isolates were grouped into five similarity groups: A-E. The largest number of isolates belonged to one of two groups: C: 60 (60%) and D: 27 (27%). In both groups C and D, SCCmec type IV was predominant (60% and 88, 8%, respectively). A total of 24% of the isolates had positive expression of PVL genes, while 76% showed a statistically significantly greater negative expression of PVL genes. Conclusion: SCCmec type IV, together with the susceptibility profile and PFGE grouping, is considered to be typical of CA-MRSA

During the period from 6th to 8th July 2018, 16th International Conference on Informatics, Management in Technology and Healthcare (ICIMTH 2018) was held in Athens. The title of the 16th ICIMTH Conference was: “Data Informatics and Technology: an Inspiration for Improved Healthcare”. At the Conference were presented: 6 keynotes, 70 papers, 29 poster presentations, 1 Invited workshop and 1 Special Panel Session by presenters from over 30 countries in the world.

Resistive random access memory (RRAM) is considered an attractive candidate for next generation memory devices due to its competitive scalability, low-power operation and high switching speed. The technology however, still faces several challenges that overall prohibit its industrial translation, such as low yields, large switching variability and ultimately hard breakdown due to long-term operation or high-voltage biasing. The latter issue is of particular interest, because it ultimately leads to device failure. In this work, we have investigated the physicochemical changes that occur within RRAM devices as a consequence of soft and hard breakdown by combining full-field transmission x-ray microscopy with soft x-ray spectroscopic analysis performed on lamella samples. The high lateral resolution of this technique (down to 25 nm) allows the investigation of localized nanometric areas underneath permanent damage of the metal top electrode. Results show that devices after hard breakdown present discontinuity in the active layer, Pt inclusions and the formation of crystalline phases such as rutile, which indicates that the temperature increased locally up to 1000 K.

The research includes analysis of: pH value, organic matter content, and the total concentration of manganese in eleven soil samples from different localities northeast of Bosnia and Herzegovina. Sequential extractions of soil samples were also performed to determine the content of some form of binding manganese. Concentration of manganese in the flowers of calendula were also found and tested at these sites. From the obtained measurement, BCF (Bioconcentration Factor) values were calculated for the tested metal. Soil pH had values from 7.84 to 8.54, which puts them in the category of alkaline and strongly alkaline soil. The total concentration of manganese measured in soil samples do not exceed the limit values or are above average values. In the analyzed soil samples, the minimum content of manganese in the exchangeable fraction and the largest in the residual fraction and bound for oxides of manganese and iron. The concentrations of manganese in the flowers of calendula have not exceeded the permitted value. Statistical analysis of the results showed a weak linear correlation between pH value of an aqueous solution of the soil and the content of manganese in the flower, and linear correlation between manganese in the exchangeable fraction and the content of manganese in the flower. The calculated BCF values are very low and suggest that calendula growing on alkaline soil hasn’t got an expressed potential for accumulation of manganese.
