72. Časovna študija sestojne inventure z aplikacijo MOTI na zasebni gozdni posestiAndrej Ficko, Helena Smrekar, 2023, original scientific article Abstract: Z razvojem digitalnih orodij postaja izvedba gozdne inventure na zasebni gozdni posesti dostopnejša, hitrejša in preglednejša. V raziskavi smo v okviru projekta EIP Digigozd na šestih gozdnih posestih proučevali porabo časa za merjenje sestojne temeljnice, števila dreves in zgornje sestojne višine s slovensko različico mobilne aplikacije MOTI ter hitrost učenja merilcev. Lastniki so izvedli meritve na 149 vzorčnih ploskvah v štirinajstih sestojih, pretežno debeljakih. Zbrane meritve smo analizirali na sestojni ravni, ravni posesti in skupaj. Pri skoraj vseh lastnikih se je izkazal negativen eksponentni učinek učenja na porabo časa za inventuro, ki je v povprečju znašala 10 min/ploskev. Na podlagi mešanega linearnega modela smo ugotovili, da ob upoštevanju razlik med lastniki in med sestoji na porabo časa značilno vpliva le zaporedna številka meritve. To pomeni, da vsaj v začetni fazi, ko merilec še ni izurjen, učenje prevladujoče vpliva na hitrost izvajanja meritev. Na podlagi časovne študije in izkušenj, ki smo jih pridobili v projektu, nameravamo nadaljevati z razvojem orodij za podporo pri gospodarjenju na zasebni gozdni posesti.

76. Cardiovascular disease in children with marfan syndromeAndrej Robida, 1987, original scientific article Abstract: To study the cardiovascular changes in children with Marfan syndrome the hospital records of 27 children with this syndrome admitted to our institution between 1975 and 1984 were reviewed. Echocardiographic examinationwas done in all of them. Heart catheterization and angiocardiography were performed in 7 children. 15 children were without cardiovascular involvement (mean age 7.9 years). Twelve children with cardiovascular abnormalities (mean age 12.3 years) were significantly older than children without cardiovascular disease (P<0.02). The most frequrnt cardiovascular abnormality (9 children) was mitral valve diseas (mitral regurgitation, mitral valve prolapse with and without regurgitation). In one patient artificial mitral valve was inserted. Aortic root aneurysm was found in 7 children, in some of them in combination with mitral valve disease. Fusiform aneurysm of thoracic aorta together with aortic root aneurysm was present in one child. In 2 patients tetralogy of Fallot was diagnosed. This review shows that the cardiovascular system is more frequently affected in older children and that about half of the children suffer from cardiovascular disease. Mitral valve involvement predominates. Surgery for the correction of the cardiovascular abnormalities in children with Marfan syndrome is seldom required.

77. Complications in cardiac catheterization and angiocardiography in infants and childrenAndrej Robida, 1987, original scientific article Abstract: Complications of cardiac catheterization and angiocardiography were reviewed retrospectively in 1074 neonates, infants, and children studied from 1st January 1981 to 31st December 1985. Overall complication rate was 5.2% (56 complications in 54 children). There were 3 cases of complications was 3.8% and was higher in infants younger than 4 months (P<0.001), and in moderalety and critically ill patients than in asymptomatic and mildly ill patients (P<0.001). The highest proportion of major complications occured in patients with truncus arteriosus communis, double outlet right ventricle, atrioventricular septal defect, univentricular heart, transposition of the great arteries, and tetralogy of fallot. Arrhythmias were encountered in 66.1%of all major and minor complications. In minor complications the differences in frequency were not found beteen various age and clinical groups (P>0.05). The study showed that higher catheterization risk of major complications could be predicted from the age, clinical status, and heart defect of the patient.

78. Percutaneous transluminal angioplasty of an aortic recoarctation : case reportDušan Pavčnik, Andrej Robida, 1987, original scientific article Abstract: Two cases of successful dilatation of recoarctation of the aorta due to a subclavien turndown operation are reported. In both cases Grüntzig technique was used. The first patient, aged 10 months, had the gradient rediced from 40 mm Hg to 10 mm Hg. The second, aged 1 year, had the gradient reduced from 80 mm Hg to 30 mm Hg. In the second patient right femoral pulse disapeared after procedure and surgery (thrombarteriectomy) was performed.

80. Truncus arteriosus - angiokardiografski prikazAndrej Robida, Darja Fettich, Dimitrij Bartenjev, Nedeljko Krevs, 1984, original scientific article Abstract: Opisali smo angiokardiografsko diagnostiko trunkusa arteriozusa komunisa (TAC)pri dvanajstih otrocih. Ker je možno paliativno in korektivno kirurško zdravljenje, moramo poleg hemodinamike TAC prikazati tip trunkusa, položaj defekta v septumu prekatov, lego arkusa, regurgitacijo skopzi trunkusno zaklopko, anatomijo pljučnih arterij in dodatne anomalije. Pri dveh otrocih smo našli dekstrokardijo, pri vseh situs solitus atrijev in samo pri enem diskordantno atrioventrikularno povezavo. Atrioventrikularni zaklopki sta bilipri vseh perforirani. 3 otroci so imeli univentrikularno srce nedoločljivega tipa. Pri 5 je šlo za TAC tip I, pri 7 pa za tip II in III. Defekt v septumu ventriklov je bil prisoten pri vseh. Trunkusna zaklopka je bila pri 7 trolistna, pri 5 števila listov nismo mogli določiti. Regurgitacijaje bila pri 2, pri 2 je ni bilo, pri ostalih je nismo mogli določiti. Aortni lok je bil pri 5 otrocih desni. Pri 7 otrocih smo ugotovili normalno širino pljučnih arterij, bilateralno hipoplazijo pri 2, hipoplazijo desne veje pri 1, pri enem je šlo za bandažo in pri 1 je bila odsotna leva veja. Pri 1 je šlo za trikuspidalno regurgitacijo in pri 1 za aberantno levo arterijo subklavijo.
