14. Long term follow-up after radiosynovectomy with yttrium 90 in patients with different rheumatic diseasesMojca Golja, Nataša Budihna, Igor Batagelj, 1997, izvirni znanstveni članek Povzetek: The aim of the retrospective study was to evaluate the efficacy of radiosynovectomy (with yttrium 90) mainly in patients with rheumatoid arthritis, less with some other rheumatic diseases. The evaluation period varied from half to nine years. The procedure was performed in 273 patients (225 females, 48 males) or in 463 joints (402 knees, 61 shoulders and ankles).The effects was evaluated by change in degree of morning stiffiness, pain and swelling (score from 0 to 9). Very good results were obtained in 69 (15%), good in 142 (30.5%), moderate in 197 (42.5%) and no effect in 55 (12%) joints. Six months after the procedure 38 joints (8%), half to two years after221 joint (48%) were in good remission, after 3 to 4 years 95 joints (20%), after 5 to 6 years 57 joints (12%) were well, 7 to 9 years later 52 joints (11%) showed no signs of arthritis. Joint pain and swelling were the most frequent procedure complications (5.6%). In two patients with additional immunomodulating therapy chronic myeloid and lymphocityc leukaemia were diagnosed. Radiosynovectomy is considered to be an effective and safe treatment for synovitis indifferent rheumatic diseases.

15. Raman microspectroscopy of garnets from Sfibulae from the archaeological site Lajh (Slovenia)Saša Kos, Matej Dolenec, Judita Lux, Sabina Dolenec, 2020, izvirni znanstveni članek Povzetek: Garnets (19 pieces) of Late Antique S-fibulae from the archaeological site at Lajh-Kranj (Slovenia) were analysed with Raman microspectroscopy to obtain their mineral characteristic, including inclusion assemblage. Most garnets were determined as almandines Type I of pyralspite solid solution series; however, three garnets showed a higher Mg, Mn and Ca contents and were determined as almandines Type II. Most significant Raman bands were determined in the range of 169–173 cm−1 (T(X2+)), 346–352 cm−1 (R(SiO4)), 557–559 cm−1 (ν2), 633–637 cm−1 (ν4), 917–919 cm−1 (ν1), and 1042–1045 cm−1 (ν3). Shifting of certain Raman bands toward higher frequencies was the result of an increase of the Mg content in the garnet composition, which also indicates the presence of pyrope end member in solid garnet solutions. Inclusions of apatite, quartz, mica, magnetite, ilmenite, as well as inclusions with pleochroic or radiation halo and tension fissures (zircon), were found in most of the garnets. Rutile and sillimanite were found only in garnets with the highest pyrope content. Spherical inclusions were also observed in two garnets, which may indicate the presence of melt or gas residues. The determined inclusion assemblage indicates the formation of garnets during medium- to high-grade metamorphism of amphibolite or granulite facies. According to earlier investigations of the garnets from Late Antique jewellery, the investigated garnets are believed to originate from India.

16. Posebnosti anestezije pri morbidno debelem bolniku z rakom : prikaz primeraIztok Potočnik, Tea Nizič, Branka Stražišar, 2023, pregledni znanstveni članek Povzetek: Debelost je kronična bolezen, za katero je značilno čezmerno kopičenje maščevja v telesu. Debeli bolniki imajo pogosto številne pridružene bolezni ter anatomske in presnovne spremembe, ki so povezane z večjim tveganjem za zaplete v perioperativnem obdobju. Debelost tako pomembno vpliva na izbiro anestezijske tehnike in zahteva multidisciplinarni pristop. V prispevku predstavljamo primer 60-letne bolnice z rakom na debelem črevesu in indeksom telesne mase (ITM) 48,1 kg/m2. Perioperativno smo jo obravnavali v skladu s protokolom za hitro okrevanje po kirurškem posegu (angl. Enhanced Recovery After Surgery, ERAS). Pred kirurškim posegom smo ocenili morebitna tveganja in jih upoštevali pri vodenju anestezije med kirurškim posegom. Po posegu smo bolnico obravnavali v enoti intenzivne terapije (EIT). V prispevku se osredotočamo na anesteziološke vidike perioperativnega vodenja. Čeprav je debelost nedvomno pomemben dejavnik tveganja kirurškega zdravljenja, pa v novejših raziskavah poročajo tudi o ugodnih vplivih debelosti z manjšo perioperativno obolevnostjo in smrtnostjo. Gre za t. i. paradoks debelosti, saj čezmerna telesna masa velja za zaščitni dejavnik, ki varuje pred zapleti kirurškega zdravljenja, kar smo potrdili tudi v našem primeru. Hkrati smo opredelili kritične točke pri anesteziji morbidno debelega bolnika in tista področja, na katerih lahko anesteziologi – ob upoštevanju protokola ERAS – pomembno prispevamo k bolnikovemu čim hitrejšemu okrevanju

19. Obsevanje kraniospinalne osiGregor Kos, 2022, objavljeni znanstveni prispevek na konferenci Povzetek: Kraniospinalno obsevanje (CSI) zajema celotno cerebrospinalno os (od glave do tekalne vrečke) in ga
uporabljamo za zdravljenje tumorjev, ki so nagnjeni k razsoju v cerebrospinalni likvor. Najpogostejša indikacija je meduloblastom, saj se v 20-30 % razširi v likvor, hkrati pa je zelo radiosenzitiven (in ga v 70 % ozdravimo z obsevanjem). CSI je zahtevno zaradi velikega in kompleksnega obsevalnega volumna in potencialnega obsevanja vseh pomembnih organov. Obsevanje zato zahteva skrbno imobilizacijo pacienta (v pediatrični populaciji pogosto s splošno anestezijo) ter izkušeno planiranje.

20. Solid carriers of potentially toxic elements and their fate in stream sediments in the area affected by iron ore mining and processingSaša Kos, Nina Zupančič, Mateja Gosar, Miloš Miler, 2022, izvirni znanstveni članek Povzetek: The potential environmental impact of historical mining and ore processing on stream sediments and water was studied in a small siderite iron ore deposit with diverse sulfide mineral paragenesis. The main aim was to characterize solid carriers of potentially toxic elements (PTEs) in stream sediments and mine waste, to understand their fate in fluvial systems. General mineralogy (X-ray powder diffraction) and individual solid PTE carriers (scanning electron microscopy/energy dispersive spectroscopy) were correlated with the geochemical composition of stream sediments, mine waste, and stream waters (inductively coupled plasma mass spectrometry). Primary solid PTE carriers were pyrite, chalcopyrite, sphalerite, Hg-bearing sphalerite, galena, and siderite. Slightly alkaline and oxidizing conditions in stream water promoted the transformation of primary phases into secondary PTE carriers. Fe(Mn)-oxide/oxyhydroxides were major sinks for Pb, Zn, and As. Compared to background levels, Co (14.6 ± 2.1 mg/kg), Cu (30 ± 2.9 mg/kg), Ni (32.1 ± 2.9 mg/kg), Pb (64.5 ± 16.4 mg/kg), Zn (175.3 ± 22.5 mg/kg), As (81.1 ± 63.7 mg/kg), and Hg (2 ± 0.8 mg/kg) were elevated in mining area. Mine waste contained similar PTE carriers as stream sediments, but much higher PTE contents. Prevailingly low PTE concentrations in streams, with the exception of As (1.97 ± 2.4 µg/L) and Zn (4.5 ± 5.7 µg/L), indicate the stability of PTE carriers. Environmental effects were not significant, and additional monitoring is recommended.
