Superior Mesenteric, Celiac and Common Hepatic Arterial Blood Flow in Healthy Adults : Hemodynamic Appraisal with Color Doppler Flow Imaging
No full textA description is given of color Doppler signals recorded in the superior mesenteric artery, celiac artery, and common hepatic artery in 15 healthy adults. Our observations showed the color Doppler flow imaging technique to be very promising for the evaluation of vascular supply to various abdominal organs as well as for providing useful information on organ perfusion
Leprosy in Croatia in the twentieth century
No full textEven today, leprosy is a relatively frequently occurring disease, especially in tropical regions of the world. From the eleventh to thirteenth century, leprosy pandemics affected Europe, including Croatia. Probably as a consequence of such history, one can still find endemic foci of leprosy in present-day Croatia. The aim of this study was to analyse all cases of leprosy registered in Croatia during the twentieth century ; therefore, we studied thoroughly existing medical documentation and published reports on sporadic leprosy cases, and went on to collect the relevant data through on-site investigation in those parts of Croatia known as putative endemic foci of leprosy. In this way, we collected data concerning the number of leprosy cases, the probable sources of infection, and traced the possible paths of spread of the disease. During the twentieth century, 17 cases of leprosy were registered in Croatia. However, due to the loss of medical documentation concerning the cases from Metković, the total number was obviously slightly greater. Concerning the 17 analysed cases, 4 patients were most probably infected during their visits (as sailors or immigrant workers) to the Middle East, South America or Africa ; 3 patients developed leprosy after prolonged close contact with previously infected family members, while the exact source of infection remains unsettled for the remaining 10. However, 2 of these patients originated from the area of Cazin in Bosnia and Herzegovina, which is known to be an endemic focus of leprosy. Furthermore, the remaining 8 came from the small area of the village of Blizna in the Croatian municipality of Trogir, and therefore it seems reasonable to conclude that Blizna represents the endemic focus of leprosy in Croatia. The last case of leprosy in Blizna was registered back in 1956. Nevertheless, it is clear that sporadic cases of leprosy can reappear in Croatia, originating either from this endemic focus of Blizna, or as an infected person returning to Croatia from abroad. So, we can conclude that, even today, Croatian medical doctors (and especially dermatovenereologists) should still be acquainted with the clinical diagnosis of leprosy and basic principles of its treatment
Angiografska analiza patoloških promjena vertebralnih arterija u dijagnostici ishemije mozga
No full textCilj ispitivanja ovog rada bio je angiografski utvrditi učestalost promjena na arteriji vertebralis, supklaviji i trunkus brahiocefalikusu kod bolesnika sa simptomima ishemije mozga, usporediti nalaze s promjenama istih arterija kod bolesnika bez simptoma, te pronaći korelaciju s patološkim promjenama na arteriji karotis. lspitivanja su obavljena analizom angiograma 100 bolesnika koji su uzastopno upućeni na angiografiju luka aorte zbog simptoma cerebrovaskularneIshemije. Kontrolnu skupinu sačinjava 30 bolesnika bez simptoma cerebrovaskularne ishemije. Rezultati su pokazali da su patološke promjene arterije vertebralis 3,3 puta češće u ispitivanoj, nego u kontrolnoj skupini. Najveće razlike u korist ispitivane skupine našli smo kod blažeg stupnja stenoze, zatim kod »kinkinga« i hipoplazije arterije vertebralis. Patološke promjene trunkus brahiocefalikusa bile su također češće u ispitivanoj skupini (za 50%), a kod arterije supkalvije dvostruko češće. Suprotno tome, stenotičko-obliterativne promjene ekstrakranijalnih dijelova arterije karotis našli smo jednako često u kontrolnoj i ispitivanoj skupini.The aim of this work was to prove angiographically the frequency of changes on the vertebral artery, subclavian artery and brachiocephalic trunk in patients with symptoms of cerebral ischaemia, to compare the results with the changes on the same arteries in patients without symptoms, and to find a correlation with pathological changes on the carotid artery. The examinations have been done by means of angiograms analysis in a hundred patients who underwent consecutive angiography of the aortic arch because of cerebrovascular ischaemia symptoms. The control group consisted of 30 patients without cerebrovascular ischaemia symptoms. The results have shown that pathological changes of vertebral arteries were 3.3 times more frequent in the examined than in the control group of patients. The greatest number of changes have been found in the examined group with milder degree of stenosis, as well as in kinking and hypoplasia of the vertebral arteries. Pathological changes of brachiocephalic trunk have been frequent too in the examined group (50%), and twice as frequent in subclavian artery. Opposite to this, pathological changes have been equally frequent in the control and examined groups
