A prospective study, which lasted from September 2014 to October 2016, covered the subjects who were examined for various benign tumor changes on the skin. The examinees were divided into 2 groups. The first group A (92 examinees) was composed of the examinees who inhabited a rural area. The second group B (98 examinees) was consisted of examinees who lived in an urban environment. The analyzed examinees gravitate towards rural and urban areas of Banja Luka, Gradiska, Stanari, Prijedor and Teslic in Bosnia and Herzegovina. The aim of this study is to analyze the attitude of examinees from rural and urban areas towards skin tumors. Parameters that were used for comparison of results are: personal attitude to skin tumors and previous skin examinations. There was no statistically significant difference in terms of prejudices among the respondents: that there is no risk of skin cancer, if a person is not exposed to the sun, and/or if changes in the skin are innate, as well as in the number of examinees who said they were not afraid of a skin tumor. In group A the number of examinees that have no opinion about skin tumors is three times higher, while in group B the number of examinees who said that they had a phobia of skin cancer is three times higher. It turned out that regular self-examination of the skin in group A is performed only by 7 (7.6%) examinees, while in group B it is done by 21 (21.5%) examinees, which proved to be statistically significantly different. Occasionally skin examination by a specialist family doctor (and/or a dermatologist) has been performed by 3 (3.3%) examinees of group A and 10 (10.3%) from group B. 4 (4.1%) examinees from group B and no one from group A perform dermoscopic examination occasionally. It was found that regular dermoscopy inspections or skin examinations by a specialist family doctor and/or dermatologist have not been done by any examinees from both analyzed groups. Attitude toward skin tumors of group A is more leisurely (less responsible), so for that group there is a possibility of higher risk degree for late diagnosis of malignant skin tumors.

Acute respiratory distress syndrome (ARDS) is a severe pulmonary disease first described in 1967 by Dr. Thomas L. Petty and colleagues as a syndrome of respiratory failure that presents with progressive arterial hypoxemia refractory to oxygen therapy, severe dyspnea caused by reduction of pulmonary compliance and diffuse bilateral pulmonary infiltrations. This clinical syndrome is characterised by acute, severe and life threatening respiratory insufficiency with high mortality rate [1-3]. The definition of ALI/ARDS was recommended by the American/ European Consensus Conference since 1994 (Table 1). The standard definition classifies the patients with bilateral pulmonary infiltrates and arterial hypoxemia, who have the ratio of PaO2 / FiO2 less than 300 mmHg. However, if the ratio is less than 200 mmHg, the diagnosis of ARDS can be made. In patients with left heart disease, the pulmonary wedge pressure less that 18 mmHg is a criterion to distinguish ARDS form cardiac failure. Recently, new Berlin classification of ARDS was accepted in 2013, where the term ALI was abandoned and ARDS was categorized [3,4].

Rezime U slučaju austenitnih nerđajućih čelika, azot se može smatrati legirajućim elementom. Jedan od razloga je to što azot, kao intersticijski rastvoren u kristalnoj rešeci železa, doprinosi poboljšanju zateznih karakteristika, prvenstveno napona tečenja. Dodatno, zahvaljujući svom jakom austenitotvornom delovanju doprinosi povećanju stabilnosti austenita, čime je omogućena delimična supstitucija skupog i deficitarnog nikla. Legiranjem metala šava austenitnih nerđajućih čelika azotom moguće je uticati na njegove osobine. Kod postupaka zavarivanja sa gasnom zaštitom, metal šava se može legirati i putem dodavanja azota u zaštitni gas. U ovom radu su razmotreni neki od efekata dodavanja azota u argon zaštitni gas kod TIG zavarivanja austenitnog nerđajućeg čelika X5 CrNi 18 10. Abstract In the case of austenitic stainless steels, nitrogen can be considered as alloying element. One reason is that the nitrogen, interstitially dissolved in the crystal lattice of iron contributes to improved tensile properties, primarily of the yield point. In addition, thanks to its strong austenite forming action contributes to increasing the stability of austenite, thereby enabling partial substitution of expensive and scarce nickel. Alloying of the weld metal of austenitic stainless steels with nitrogen can affect its properties. In welding processes with gas protection, weld metal can also be alloyed through the addition of nitrogen in the shielding gas. This paper discusses some of the effects of the addition of nitrogen in argon shielding gas at TIG welding of austenitic stainless steel X5 CrNi 18 10.

Istražena je povezanost prevalencije i etiologije supklinickog mastitisa s pojavnoscu klinickog artritisa u 543 francuske alpske koze seroloski pozitivne na virus artritisa-encefalitisa (AEK) iz proizvodnih farmi sa sjeverozapada Hrvatske. Cilj je bio odrediti je li seroloska pozitivnost na AEK povezana s pojavnoscu supklinickog mastitisa bakterijske etiologije i istražiti je li AEK glavni uzrok pojavnosti klinickog artritisa u pretraženih koza. Sve su koze bile pregledane na pojavu klinickog artritisa. Uzorci krvi iz jugularne vene bili su testirani na AEK imunoenzimnim testom. Uzorci mlijeka, uzeti iz svake polovine vimena zasebno, pretraženi su na prisutnost bakterijskih uzrocnika mastitisa. Svi prikupljeni podatci unakrsno su klasificirani u kontingencijskim tablicama. Od ukupnog broja koza, AEK je seroloski potvrđen u 50, 8%. Supklinicki mastitis je potvrđen u 52, 3% koza. Istodobna pojava supklinickog mastitisa i AEK zabilježena je u 30% od ukupnog broja, dok je 21, 9% koza s klinickim artritisom bilo seroloski pozitivna na AEK. Statisticke su analize potvrdile pozitivnu povezanost pojave supklinickog mastitisa i AEK seropozitivnosti. Slicni su rezultati dobiveni i za povezanost pojavnosti klinickog artritisa i AEK seropozitivnosti. Također je zabilježena slaba pozitivna povezanost između supklinickog mastitisa i klinickog artritisa. Rezultati upucuju na to da bi AEK mogao utjecati na ucestalost supklinickog mastitisa. Rezultati također nalažu dodatno istraživanje AEK infekcije kao glavnog uzroka pojave klinickog artritisa u istraženim stadima.
