Introduction: Paracetamol (Acetaminophen) in addition to aspirin is the most commonly used analgesic and antipyretic medication by millions of patients worldwide. It is an example that paracetamol as medicine that in the world is provided without a doctor’s prescription, can lead to death. Today paracetamol became an integral part of a heroin mixture and is very popular at the street market. The main reason for this is that it can be obtained without a prescription, it is cheap, and by most people well tolerated without side effects. It is probably used for “cutting” the pure heroin, as it says in the jargon, and in that manner from small amount of pure drug is obtained greater amount, which is then sold on the street. The goal is to identify presence of paracetamol, by analytical method of gas chromatography mass spectrometer (GC-MS) in postmortem material together with psychoactive substances. Material and methods: For chemical-toxicological analysis is used biological material collected trough autopsy of 20 deceased people, suspected to have died due to psychoactive substance overdose. All received samples are stored at -20 ° C until analysis at our laboratory. From processed 47 samples that were analyzed in the period from 2014 to 2015, 19 are blood samples, urine 19, 3 samples of stomach contents, and 6 samples of bile content. Deceased were middle-aged, of which only 7 were female. The tested samples were processed according to two methods of extraction. Extraction by XAD-2 resin, and the extraction by the method of salting out with sodium tungstate. Extracts of the samples were then dissolved in chloroform and continued analysis at the analytical instrument. Identification of the paracetamol presence, in the test biological samples is demonstrated by the technique of gas chromatography with mass spectometry (hereinafter referred to as GC-MS). The technique of GC-MS is a selective, sensitive and reliable, and is therefore considered a “gold standard” for determining the drug, and the drug substance. Used GC-MS instrument was an Agilent 7890A with helium as the carrier gas. Results: The analysis of blood samples, urine, bile and stomach contents, obtained after the autopsy of deceased persons, by using gas chromatography with mass spectrometry, in analytical manner confirmed the fact that paracetamol is a very common component of psychoactive substances poisoning. In our assay of samples we detected psychoactive substances (heroin, codeine, morphine, sertraline, diazepam), and almost all were found in the combination with paracetamol, indicating the poor quality of illicit drugs sold on the market. Discussion: Paracetamol (Acetaminophen) is a very common component in mixtures of street drugs. Such mixtures almost anyone can afford, but the very quality of these drugs has become extremely low, because it does not sell the pure substance, but is mixed with various medications. According to research Pantazia et al. the heroin mixture proportion of the heroin is very small so a lot of that mixture has only 3% of heroin, a large number of cases can be only 1% of pure heroin. Most of the time it replaces caffeine and paracetamol. According to the Risser et al. reason why acetaminophen component is present in these mixtures is because it can be purchased without a prescription, it is cheap, well tolerated by most people and shows no side effects. Conclusion: When we talk about illegal drugs, we must emphasize the fact that there is no quality control, or the composition of the drug. The composition of the drug purchased on the black market is still unknown to potential user. While reaching the final drug users it pass through many hands, and at each step something is added to increase earnings. Most often present additives or impurities in narcotic drugs that are added are caffeine, ephedrine, acetaminophen, acetylsalicylic acid (aspirin) and additives such as powders, cement and chalk.

Various High Dynamic Range (HDR) deghosting algorithms have been developed to solve the problem of merging dynamic content in multi-exposure HDR imaging. Even though these algorithms may be successful in `ghost' removal, they may fail to reduce noise in the resultant HDR image. As a result, the presence of noise in the generated HDR image degrades the overall image quality. HDR deghosting algorithms should also aim to reconstruct values that are approximately proportional to the luminance of the real scene. In this work we evaluate noise and luminance reconstruction in HDR images generated by five state-of-the-art HDR deghosting algorithms. The observations based on the obtained results are instrumental to guide the development of new HDR deghosting algorithms that will also aim to reduce noise and reconstruct original scene luminance to produce a good quality deghosted HDR image.

Objective: Timely recognition and optimal management of atherogenic dyslipidemia (AD) and residual vascular risk (RVR) in family medicine. Background: The global increase of the incidence of obesity is accompanied by an increase in the incidence of many metabolic and lipoprotein disorders, in particular AD, as an typical feature of obesity, metabolic syndrome, insulin resistance and diabetes type 2. AD is an important factor in cardio metabolic risk, and is characterized by a lipoprotein profile with low levels of high-density lipoprotein (HDL), high levels of triglycerides (TG) and high levels of low-density lipoprotein (LDL) cholesterol. Standard cardiometabolic risk assessment using the Framingham risk score and standard treatment with statins is usually sufficient, but not always that effective, because it does not reduce RVR that is attributed to elevated TG and reduced HDL cholesterol. RVR is subject to reduction through lifestyle changes or by pharmacological interventions. In some studies it was concluded that dietary interventions should aim to reduce the intake of calories, simple carbohydrates and saturated fats, with the goal of reaching cardiometabolic suitability, rather than weight reduction. Other studies have found that the reduction of carbohydrates in the diet or weight loss can alleviate AD changes, while changes in intake of total or saturated fat had no significant influence. In our presented case, a lifestyle change was advised as a suitable diet with reduced intake of carbohydrates and a moderate physical activity of walking for at least 180 minutes per week, with an recommendation for daily intake of calories alignment with the total daily (24-hour) energy expenditure (24-EE), depending on the degree of physical activity, type of food and the current health condition. Such lifestyle changes together with combined medical therapy with Statins, Fibrates and Omega-3 fatty acids, resulted in significant improvement in atherogenic lipid parameters. Conclusion: Unsuitable atherogenic nutrition and insufficient physical activity are the new risk factors characteristic for AD. Nutritional interventions such as diet with reduced intake of carbohydrates and calories, moderate physical activity, combined with pharmacotherapy can improve atherogenic dyslipidemic profile and lead to loss of weight. Although one gram of fat release twice more kilo calories compared to carbohydrates, carbohydrates seems to have a greater atherogenic potential, which should be explored in future.

Aim: To determine the possible relation between intraocular pressure (IOP), central corneal thickness (CCT) and corneal resistance (CR) in kerotoconic eyes before, 3,6 and 12 months after collagen crosslinking procedure (CXL) with aim to find out does the thicker cornea means already more resistance cornea followed with higher IOP. Methods: Thirty eyes (30 patients) with central keratoconus (KC)were evaluated in retrospective cross sectional study. The corneal biomechanical parameters were taken with Wave Light Allegro Oculyzer produced by Alcon before the CXL, 3, 6 and 12 months after the procedure. IOP were checked by Goldmann applanation tonometry (GAT) before, 3, 6 and 12 months after CXL. Results: The value of IOP before the CXL was 12,0 mmHg (10,62-15,25 mmHg), 3 months later 13,5 mmHg (11,0-16,0 mmHg), 6 months 14,0 mmHg (11,0-16,0 mmHg) and 12 months later 15,0 mmHg (10,37-17,25 mmHg) and was statistically significant higher (p=0,015) comparing to the value of IOP 3 months after the CXL, IOP 12 months after CXL procedure was statistically significant higher comparing to preoperative values (p=0,010). There were no statistically significant difference between the values 3 and 6 months after CXL. The CCT before the CXL procedure was 449 (433-505,75 microns), 3 months after CXL was 420 (383-473microns, p < 0,005), 6 months later 437 (401,25-480,25, p=0,001), 12 months after CXL 437 (401-503 microns, p=0,001). However there is statistically significant difference in CCT 12 months after CXL 437 (401-503microns p=0,032) and the value of CCT 3 months later the procedure (p=0,004) and the CCT 12 months after CXL and the value of CXL 6 months after CXL (p=0,036). The value of CCT did not show any statistically significant difference 3 and 6 months postoperatively. Conclusion: After riboflavin-UVA CXL in eyes with KC there was significant decrease in central corneal thickness 3 and 6 months after the procedure and the thickness is almost the same 12 months later. However IOP is low before CXL, raising up 3 and 6 months after CXL but significant increase is seen 12 months later. It means the regular measurement of IOP could be the serious and confident indicator of increasing of corneal resistance which is the main goal of CXL treatment.

Na temelju prvih osmanskih popisa u radu se daje prikaz stanja na prostoru novoosnovane nahije Mostar, neposredno nakon osmanskoga osvajanja. Izravna posljedica osvajanja bio je velik broj pustih i polupustih naselja. Povlasticama i oslobađanjem od pojedinih obveza nove su vlasti nastojale privoljeti izbjeglo stanovništvo da se vrati svojim domovima, ali i naseliti novo. Poduzete mjere pozitivno će se odraziti na povratak stanovništva, tako da će samo nekoliko godina nakon osvajanja broj pustih mjesta biti smanjen.
