ABSTRACT:The aim of the submitted work was to analyze the outlook of logging perspectives in the next two decades (2013)(2014)(2015)(2016)(2017)(2018)(2019)(2020)(2021)(2022)(2023)(2024)(2025)(2026)(2027)(2028)(2029)(2030)(2031)(2032) for all forests in the territory of the Czech Republic. The analyses made use of the national database of forest management plans and guidelines. For the purpose of these analyses, the forests were divided into commercially exploitable forests and forests commercially exploitable with restrictions. The latter ones included protection forests and the category of special purpose forests, i.e. 31c -forests in the territory of national parks and national nature reserves, and 32a -forests occurring in the first zones of protected landscape areas, and forests occurring in nature preserves and nature monuments. In addition to the potential total volume of timber logging, perspectives were studied separately for coniferous and broadleaved tree species as well as for individual main tree species. The derived model mean annual cut of 15.51 mil. m 3 corresponds to the current timber production in the Czech Republic. Results of the analyses indicate that reduced logging of coniferous, namely spruce, timber is to be expected in the next twenty years.

Souhrn:Autoři prezentují případ pa cientky s nejasnou stenózou terminálního choledochu projevující se ikterem a opakovanými ataky akutní cholangoitidy. Popisují dia gnostický postup ke zjištění etiologie stenózy, přičemž vylučují jak maligní etiologii stenózy, tak se zabývají též diferenciální dia gnózou benigní etiologie stenóz. Přesto bylo k definitivnímu zjištění zapotřebí až klinické pitvy (pro rychle progredující klinický stav pa cientky), která odhalila adenokarcinom žlučníku s generalizací do duodena, pankreatu, peripankreatických lymfatických uzlin, do plic a žlučových cest, kde vytvářel stenózu choledochu. Na závěr byly podány základní informace o karcinomu žlučníku, jeho incidenci, rizikových faktorech, dia gnostice a léčbě. Klíčová slova: hlavní žlučový vývod -stenóza -žlučník -malignitaSummary: The authors present a case report of a patient with unclear terminal common bile duct stenosis, presenting as jaundice and repeatable acute cholangitis. They describe procedures used to identify the etiology of stenosis. They exclude malignant etiology and pursue a differential diagnosis of stenosis with benign etiology. Nevertheless, it was necessary to perform autopsy (due to rapid progression of the patient's health), which revealed adenocarcinoma of the gallbladder, with dissemination to the duodenum, pancreas, lymph nodes, lungs, and bile duct, resulting in stenosis of ductus choledochus. The authors discuss gallbladder cancer, incidence, risk factors, diagnostics, and therapy.
