Re: Aortoduodenal Fistula Three Years After Aortobifemoral Bypass: Case Report and Literature Review
No full textWHAT IS HOMELAND TO A GASTARBEITER?
No full textRad tematizira pomalo zapostavljeno djelo Ivana Raosa: Gastarbajteri. U vrijeme kad je bilo objavljeno, 1982., bilo je aktualno temom, dan-danas još i više s obzirom na sve veći broj (ekonomskih) emigranata iz Hrvatske. Gastarbajteri sadrže 31 novelu u kojima Raos vješto i uvjerljivo portretira likove emigranata i iz Dalmatinske zagore u zemlje zapadne Europe i Amerike. O Raosovim Gastarbajterima pisali su malobrojni: Cvjetko Milanja, Ivan Božičević i Josip Pavičić u časopisu Republika te opširnije Ana Lederer u monografiji Ivan Raos što svakako predstavlja poticaj da se ovo djelo ponovno aktualizira i (p)ostane predmetom znanstvenog i čitalačkog interesa.The paper deals with a somewhat forgotten work of Ivan Raos: Gastarbajteri. When it was published in 1982, its topic was very relatable, and today it is even more so, given the ever-growing number of Croatian (economic) migrants. Gastarbajteri is made of 31 short stories in which Raos skillfully and convincingly portrays characters of migrants from the Dalmatian hinterland to the countries of western Europe and America. Very few have written about Raos’ Gastarbajteri: Cvjetko Milonja, Ivan Božičević and Josip Pavičić in the magazine Republika, and Ana Lederer has in a more extensive manner in her monography Ivan Raos, which surely represents an encouragement to re-actualize this art work, (re)making it an object of scientific and reader interest
Mjehuravost odljevaka pri lijevanju aluminijskih legura u vakuumu
No full textLijevanje aluminijskih legura zahtijeva određeno znanje i vještinu kako bi odljevci zadovoljili određene kriterije kvalitete. Otopljeni plinovi u litni aluminija mogu se pojaviti iz više izvora, a njihovo prisustvo želi se smanjiti, budući da uvjetuju pojavu mjehura i pora. Pojavu poroznosti nemoguće je izbjeći u potpunosti, ali se pomoću odgovarajućih metoda može smanjiti na zanemarivi iznos. U prvome redu potrebno je pažnju posvetiti na samu pripremu litine budući da sa loše pripremljenom litinom svaki se slijedeći dio procesa dodatno otežava. Također, bitan faktor je i izbor materijala kalupa i jezgre, budući da u sebi imaju sastojke koji se otplinjavaju pri procesu ulijevanja litine. Tijekom godina razvijene su mnoge metode smanjenja količine otopljenih plinova, a time su odljevci postali sve kvalitetniji. Upotrebom novih tehnologija, metode kontrole odljevaka sve su više sofisticirane te su jednostavnije, a primjenjuju se bez potrebe za razaranjem uzorka. U ljevačkoj industriji javlja se potreba za stručnim kadrom koji razumije probleme koji se pojavljuju te ih je u stanju uočiti, interpretirati i po potrebi ukloniti
Thallium Toxicity in Humans
No full textTalij je u prirodi široko rasprostranjen teški metal, prisutan u vrlo niskim koncentracijama pa ga stoga ubrajamo u elemente u tragovima. Budući da organizmima nije potreban ni u jednoj razvojnoj fazi, ne ubrajamo ga u grupu esencijalnih elemenata. Talij zbog njegovih svojstava ubrajamo među najtoksičnije teške metale. Povremeno se još uvijek pojavljuju slučajevi u kojima je talij upotrijebljen kao sredstvo za pokušaj ubojstva, odnosno samoubojstva, ali i slučajevi nenamjernog, slučajnog trovanja talijem. U današnje vrijeme potencijalna o asnost od trovanja talijem postoji zbog profesionalne izloženosti, izbijanja ekološke katastrofe ili zbog akumulacije u hranidbenim lancima, uglavnom zbog uzgoja hrane na onečišćenom tlu. Sve češća uporaba talija u visokotehnološkoj industriji kao odgovor na zahtjeve moderne tehnologije neprestano povećava rizik od izloženosti svih živih organizama štetnim utjecajima talija u okolišu.
Talij ima izuzetno negativan učinak na različite organske sustave, a osobito na živčani sustav. Mehanizmi toksičnosti talija još uvijek nisu u potpunosti razjašnjeni, premda važnu ulogu imaju poremećaji metabolizma glutationa, oksidativni stres i narušavanje homeostaze posredovane ionima kalija. Nedostatak podataka o mutagenim, kancerogenim ili teratogenim učincima talija i njegovih spojeva u ljudi opravdava buduća istraživanja ovog vrlo toksičnog metala.Thallium is a naturally occurring trace element, widely distributed in the earth’s crust, but at very low concentrations. It does not have a known biological use and does not appear to be an essential element for life. It has been considered one of the most toxic heavy metals.
Occasionally, there are reports on thallium poisoning as results of suicide or murder attempt or accident. The main threat to humans is through occupational exposure, environmental contamination, and accumulation in food, mainly in vegetables grown on contaminated soil. Increasing use in emerging new technologies and demanding high-tech industry constantly raise concern about exposure risk to all living organisms. Thallium is considered a cumulative poison that can cause adverse health effects and degenerative changes in many organs. The effects are the most severe in the nervous system. The exact mechanism of thallium toxicity still remains unknown, although impaired glutathione metabolism, oxidative stress, and disruption
of potassium-regulated homeostasis may play a role. The lack of data about mutagenic, carcinogenic, or teratogenic effects of thallium compounds in humans calls for further research
Alternatives to criminal procedure against juvenile and young adult offenders and alternative to criminal procedure in the cases of domestic violence
No full textIn the paper, the author is analyzing the Act on juvenile courts of the Republic of Croatia, which foresees a broad possibility of implementing the principle of opportunity in the pre-trial, i.e. reinvestigation phase of the procedure in terms of the decision of the public prosecutor about the criminal charge against these persons, including the implementation of particular obligations as informal sanctions. Particular attention is paid to the special obligation called off-court agreement. The aim of the off-court agreement is “reconciliation between the juvenile or young adult offender and the victim of the crime, and establishment of the social peace”. Similar project and the implementation of the principle of opportunity is used in the cases of the criminal offence of domestic violence. The main aim of these obligations is to offer professional assistance to the families which are in crisis and have difficulties related to the violent behavior of one family member - mostly the father. Such an approach is more efficient than the long lasting criminal procedure, testifying and strengthening the crisis in the family. This paper gives also an insight into the legal provisions concerning this measure and its implementation in practice
Typologie von Emigrantenfiguren in der jüngeren kroatischen Literatur
No full textU radu se skicira moguća tipologija lika iseljenika u
hrvatskoj književnosti 19. i 20. stoljeća. Kako gotovo ne
postoje slični radovi u hrvatskoj književnoj historiografiji, to
se metodološki upozorava na dvije razine i dvije odvojene
teme – tretiranje navedene teme domicilne i egzilne
literature. Načelno se razlikuje tip lika ekonomske provenijencije
– zgrtalački mentalitet, uz nostalgičara doma – te lik
intelektualca umjetnika koji odlazi van iz kulturnih potreba i
konačno lik političko-ideološkog utemeljenja, kojim se više
bavila egzilna literatura.The paper outlines a possible typology of immigrant characters
in 19th and 20th century Croatian literature. Since there are
almost no similar articles in Croatian literary historiography, the
author warns methodologically of two levels and two separate
issues – the treatment of these topics in local and exile
literature. Generally, there is the type of character of economic
provenance – with a hoarding mentality, along with the home
nostalgic – as well as the figure of the artist intellectual who
emigrates to fulfil his/her cultural needs, and ultimately, the
politically and ideologically charged character, which was more
in the focus of attention of exile literature.Der Verfasser skizziert in seiner Arbeit eine Typologie von
Emigrantenfiguren in der kroatischen Literatur des 19. und
20. Jahrhunderts. Da Untersuchungen über dieses Thema in
der kroatischen Literaturwissenschaft so gut wie nicht
existieren, begleitet der Verfasser seinen Text mit dem
methodologischen Verweis, dass man dabei zwei
verschiedenen Ebenen bzw. zwei gesonderten Themen
Rechnung tragen müsse: der einheimischen Literatur
einerseits und der Exilliteratur andererseits. Grundsätzlich
lassen sich drei Typen kroatischer Auswanderer erkennen:
1. der Wirtschaftsemigrant, dem es nur auf die Anhäufung
materieller Güter ankommt und der seiner Heimat in
Nostalgie verbunden ist; 2. der Typ des Intellektuellen und
Künstlers, der aus kulturellen Bedürfnissen heraus sein Land
verlässt, und 3. der Typ des politisch-ideologisch motivierten
Emigranten, der überwiegend in der Exilliteratur thematisiert
wird
Contribution of Croatian Literary Society of St. Jerome to Croatian Literature of Christian Inspiration
No full textHrvatsko književno društvo sv. Jeronima, osnovano 1868. kao Društvo sv. Jeronima, postoji neprekidno 146 godina. Njegova je svrha promicanje i širenje kršćanske uljudbe među hrvatskim pukom, tj. promicanje i širenje kršćanskim duhom prožete književnosti, znanosti i prosvjete među svim stanovnicima Republike Hrvatske i Hrvatima diljem svijeta. U tu je svrhu Društvo izdavalo i izdaje knjige i razne časopise. Najraširenije sredstvo širenja književnosti kršćanskog nadahnuća jest kalendar “Danica” koji je do sada objavljen u 133 godišnja broja. Tijekom toga dugoga niza godina u njemu su objavljivali mnogi poznati i manje poznati pisci i pjesnici, među njima Franjo Iveković, Ivan Trnski, Dragutin Stražimir, Vjekoslav Klaić, Cvjetko Rubetić, Ferdo Rožić, Josip Zorić, Josip Kotarski, Josip Štadler, Josip Pazman, Rudolf Horvat, Rudolf Vimer, Dominik Gudek, Valentin Čebušnik, Velimir Deželić stariji, Velimir Deželić mlađi, Kerubin Šegvić, Josip Andrić, Ljubomir Maraković, Petar Grgec, Radovan Grgec i mnogi drugi.The Croatian Literary Society of St. Jerome, founded in 1868 as the Society of St. Jerome, has been continuously active for 146 years. Its purpose is to promote and spread the Christian civilization among the Croatian population, i.e. promote the literature, science and education steeped in Christian spirit among all the people of Croatia and Croats around the world. To this end, the Society has issued books and a variety of magazines. The most widespread means of spreading literature of Christian inspiration is the calendar Danica which has been published 133 times to date. During such a long period of publishing it featured works by great many well- and lesser-known writers and poets, including Franjo Iveković, Ivan Trnski, Dragutin Stražimir, Vjekoslav Klaić, Cvjetko Rubetić, Ferdo Rožić, Josip Zorić, Josip Kotarski, Josip Štadler, Josip Pazman, Rudolf Horvat, Rudolf Vimer, Dominik Gudek, Valentin Čebušnik, Velimir Deželić Sr, Velimir Deželić Jr, Kerubin Šegvić, Josip Andrić, Ljubomir Maraković, Petar Grgec, Radovan Grgec and many more
CAROTID ENDARTERECTOMY IN PATIENTS WITH ANTIAGGREGATION THERAPY
No full textNakon karotidne endarterektomije ponekad dolazi do krvarenja koje može potaknuti antiagreacijska terapija. Prednosti antiagregacijske terapije su manja učestalost tromboza i povoljan učinak kod koronarnih bolesnika. Tijekom karotidne endarterektomije kod bolesnika s antiagregacijskom terapijom smo lokalno aplicirali TachoSil spužvu. Pregledali smo radove na PubMed-u koji obrađuju karotidnu endarterektomiju, antiagregacijsku terapiju i postoperacijsko krvarenje. Kod 24 operiranih bolesnika s antiagregacijskom terapijom i intraoperacijskom primjenom TachoSil-a nije bilo postoperacijskih krvarenja. Pregled literature je pokazao da antiagregacijska terapija ipak u nekim okolnostima povećava vjerojatnost postoperacijskog krvarenja. Također, usprkos novim smjernicama značajan broj kirurga prekida antiagregacijsku terapiju prije karotidne endarterektomije. Zaključujemo da je karotidnu endarterektomiju u lokalnoj anesteziji moguće učiniti i bez prekida antiagregacijske terapije, a da pritom nema porasta učestalosti postoperacijskih krvarenja ili hematoma.Carotid endarterectomy is a common way of surgical treatment of extracranial carotid artery disease caused by atherosclerosis. Patients are often operated on under local anesthesia with intraoperative application of heparin. Postoperative bleeding occurs in up to 8% of cases, and up to 4.7% of patients need reoperation due to bleeding. TachoSil is a medical sponge consisting of collagen with added human coagulation factors (fi brinogen and thrombin). In contact with water, blood or bodily fl uids, it forms a clot that adheres to the surface. The hypothesis and aim of our study was to show that TachoSil could be topically administered during surgery on carotid arteries in order to prevent minor bleeding, without causing any local signs of infl ammation or infection. The study included a prospective series of consecutive patients that underwent surgery for extracranial carotid stenosis with concomitant antiplatelet therapy at Department of Vascular Surgery, Merkur University Hospital in Zagreb. All patients received antiplatelet therapy with aspirin or aspirin and clopidogrel until the day before surgery. From April 2, 2012 to February 8, 2013, a total of 24 patients with extracranial carotid artery stenosis were operated on, along with receiving antiplatelet therapy. All patients received 100 mg of acetylsalicylic acid and/or 75 mg of clopidogrel until one day prior to surgery. Patients had been treated with antiplatelet drugs for at least six months prior to carotid endarterectomy. Four patients had been on dual antiplatelet therapy (aspirin 100 mg and clopidogrel 75 mg) because of percutaneous transluminal angioplasty (PTA) and a stent placed in pelvic arteries or superfi cial femoral artery. Due to speech disturbances following clamping of carotid arteries in two study patients a temporary intraluminal shunt was created. These two patients underwent longitudinal arteriotomy and longitudinal endarterectomy. Arteriotomy was closed by direct suture without a patch. Following arteriotomy and partial conversion of heparin with protamine, six patients needed
additional individual sutures. Then, protamine was added again to up to the full dose of conversion (50 mg). In 19 patients, only one TachoSil medical sponge (9.5 cm x 4.8 cm) was placed, whereas in fi ve patients two sponges were placed. None of the patients (24 of them operated on between April 2, 2012 and February 8, 2013) with TachoSil placed intraoperatively had any signs of postoperative wound infection. Carotid artery stenosis is a very common disease the incidence of which increases proportionally with age of the population observed. Bleeding is a relatively common and significant complication following surgical treatment, particularly in case of arterial bleeding. Bleeding and other complications in the neck can be
very serious and challenging for surgical treatment. With the present guidelines for the administration of clopidogrel in the evening before surgery, in some circumstances an increased incidence of postoperative hemorrhage or prolonged duration of surgery can be expected. Intraoperative use of hemostatics may reduce the postoperative bleeding complications. Intraoperative application of TachoSil does not increase the rate of postoperative complications such as infection and delayed healing. TachoSil may reduce the rate of postoperative complications in carotid surgery
Inflammatory Malignant Fibrous Histiocytoma of the Retroperitoneum
No full textThe authors present a case of inflammatory malignant fibrous histiocytoma located in the left retroperitoneum. The
tumor was resected enblock with kidney and suprarenal gland. During the resection the system of retractors called the
pillars of Kocman was used which allowed wide exposure of the abdominal cavity. The tumor measured 23x17x10cm
with the left kidney and suprarenal incorporated. The tumor was centrally pseudocystic made of xanthomatous cells,
foamy cells and rare giant cells with storiform formations and infiltrated with neutrophills. Imunohistochemically, the
tumor cells were vimentin and CD 68 positive and CD 20, CD3, EMA, S-100, HMB 45, CD 34 and CD 1a negative.
Neutrophills were CD 15 positive
