One of the most common surgical procedures in veterinary surgeries, clinics and stations is certainly ovariohisterectomy. Ovariohisterectomy is surgical removal of ovaries and uterus. There are ...numerous reasons for its performance. Some are preventative and some are part of the treatment of pathological conditions. The preventive group include: prevention of estrus, pregnancy prevention and prevention of the mammary tumors. In the cases of pyometra, metritis, cysts, uterine torsion, prolapsed uterus, trauma, or vaginal prolapse, vaginal neoplasia, ovariohisterectomy is almost obligatory surgical intervention. Sometimes, ovariohisterectomy is used as a control measure in certain endocrine (diabetes), dermatological (generalized demodicosis, hormone-dependent dermatitis) and behavioral problems and diseases. In large urban areas, with numerous population of stray dogs, ovariohisterectomy is recommended as a control measure and long-term strategy of reducing their number. Sterilization is the most humane approach for solving the problem of stray dogs.
In order to collect information about the presence of priority and other substances whose quality standards are defined by Directive 2008/105/EC, the water and sediment quality monitoring was carried ...out in 6 sampling locations in four rivers and 14 sampling locations in protected areas in AP Vojvodina. The waters of the Carska Wetland, Ludas Lake and Danube River exceeded the quality standards for pentachlorobenzene, while the quality standard for cadmium was only exceeded in Carska Wetland. The priority substances detected in the sediment were lead, nickel, mercury, trifluralin, isomers of hexachlorocyclohexane (HCH), pentachlorobenzene, hexachlorobenzene, 4-octylphenol, naphthalene, anthracene, fluoranthene, benzo(b)-and benzo(k)-flouranthene, benzo(g,h,i)-perylene and indeno(1,2,3-cd)pyrene.
After an extensive analysis of the world literature (121 references), beginning from the first reported case by Antopol and Kugel, 1933, the general review of the problem stressed especially the ...following morphologic characteristics and clinical significance of the anomalous origin of the left circumflex coronary artery (LCxA) from the right coronary artery (RCA): The place of the anomalous origin of LCxA from RCA among all other variations and anomalies of LCxA. The anatomical and topographical characteristics of LCxA originating from RCA in normal heart as well as in congenital heart diseases--CHD (especially complete transposition of great arteries--TGA). The formal genesis of LCxA from RCA according to original new Ogden's theory, taking into account the dual origin of the coronary arteries and the peritruncal angioblastic ring that surrounds the developing aorta and pulmonary artery. The frequencies of the origin of LCxA from RCA in autopsy and coronarography series. The importance of LCxA (by its origin and/or caliber) in determination of the right, left or codominance of the coronary arteries including the peculiarities in cases of isolated aortic stenosis and bicuspid aortic valve. The importance of recognizing LCxA from the RCA during implantation of artificial aortic, mitral and tricuspid heart valves, during mitral valve anuloplasty, closure of ostium primum defect as well as during aorto-coronary venous bypass. The LCxA from RCA, especially its proximal segment, shows more frequent and an earlier, faster and heavier obstructive atherosclerosis, causing different manifestations of coronary heart disease and sudden death. Also, mitral insufficiency can be caused by ischemia of the papillary muscles of the left ventricle. The awareness of the possibility that LCxA may arise from the RCA can prevent many complications during cannulations of the coronary arteries for diagnostic coronarography and myocardial perfusion during heart operations. The authors presented their 30 autopsied cases of LCxA from RCA, analysing morphological and topographic data as well as their clinical significance and association with other CHD. There were 6 isolated cases and 24 cases associated with other CHD (20 with TGA and 4 with other CHD). Our first autopsied case of LCxA from RCA was diagnosed as associated with tetralogy of Fallot in 1964. During the period 1964-1985 we had 1015 cases of CHD (including 132 cases of TGA).
