Úvod: Perkutánní punkční cholecystostomie je považována za výkon v nouzi při selhávání konzervativní léčby těžké akutní cholecystitidy u starých a kriticky nemocných pacientů. Otázkou je, nakolik je v současnosti toto řešení aktuální či obsoletní. Metody: Retrospektivně byla analyzována data pacientů, kteří podstoupili v období 1/2010−1/2015 punkční cholecystostomii pod kontrolou počítačové tomografie (CT). Sledována byla data pacientů, úspěšnost a komplikace výkonu, krátkodobé a dlouhodobé výsledky. Výsledky: Punkční cholecystostomie pod CT navigací byla na Chirurgické klinice 2. LF UK a FNM za sledované období provedena u 30 pacientů. V souboru bylo 21 žen (70 %), 9 mužů (30 %), průměrný věk 78 let (SD?12,3), medián 82 let (34–93 let). Indikací výkonu byla těžká akutní cholecystitida, respektive empyém žlučníku nereagující na konzervativní léčbu u rizikových pacientů aktuálně neúnosných pro operační výkon. Primárně byla punkce úspěšná u 23 pacientů (77 %), selhala u 7 pacientů (23 %) s nutností opakované punkce u jedné pacientky a urgentní cholecystektomie u 6 nemocných. Průměrná doba hospitalizace byla 16,5 dne (SD?8,2), medián 15 dnů (7–49 dnů). Celková 30 denní mortalita byla 17 %, mortalita v souvislosti s primární indikací k výkonu byla 10 %. Recidivu onemocnění jsme zachytili u 3 pacientů (10 %). U jednoho byla řešena opakovanou drenáží, u druhého konzervativní terapií a u třetího akutní cholecystektomií. U jednoho pacienta (3 %) byla provedena odložená laparoskopická cholecystektomie bez komplikací. Závěr: Perkutánní cholecystostomie pod CT kontrolou u pacientů neúnosných k operaci představuje efektivní a bezpečnou terapeutickou možnost., Introduction: Percutaneous cholecystostomy is considered to be an emergency treatment option when conservative treatment of acute cholecystitis fails in elderly and critically ill patients. The question is: to what extent is this technique still up-to-date or obsolete. Methods: We retrospectively reviewed data of patients who underwent a computer tomography (CT) guided percutaneous cholecystostomy between 1/2010−1/2015. We analyzed the patient data, the success rate, complications of the procedure, short- and long-term outcomes. Results: 30 patients undergoing CT-guided percutaneous cholecystostomy at the Department of Surgery, 2nd Faculty of Medicine, Charles University in Prague and Motol University Hospital during the study period were enrolled. The study group included 21 females (70%) and 9 males (30%) with mean age of 78 years (SD?12.3), median 82 years (range 34−93 years). Percutaneous cholecystostomy was indicated for patients with severe cholecystitis/empyema of the gallbladder not responding to conservative therapy who were poor candidates for operative cholecystectomy. Of these, 23 patients (77%) were successfully treated with initial percutaneous cholecystostomy whereas 7 patients (23%) experienced treatment failure – one was subsequently successfully treated with repeated percutaneous cholecystostomy and six underwent emergency cholecystectomy. The mean length of stay was 16.5 days (SD ?8.2), median 15 days (7–49 days). The total 30-day mortality was 17%, and indication-related mortality was 10%. Three patients (10%) had a recurrence. One patient required repeated percutaneous drainage, the second recovered on conservative treatment and the third patient underwent acute cholecystectomy. Only one patient (3%) underwent delayed laparoscopic cholecystectomy without complications. Conclusion: CT guided percutaneous cholecystostomy is a safe and effective therapeutic modality in patients unfit for surgery., and L. Martínek, D. Kostrouch, J. Hoch
The basis for most acute coronary events is either rupture or fissuring of unstable atherosclerotic plaques with subsequent thrombosis leading to coronary artery occlusion. The development of atherosclerotic plaques takes several decades, but the mechanical features determining its stability and the risk of rupture can change very rapidly depending on a number of internal factors. Unstable plaques have a large lipid core, a thin overlying fibrous cap and an abundance of inflammatory cells. The most important factor determining the plaque stability is the plasma level of atherogenic LDL particles. Increased levels of these particles cause endothelial dysfunction with impaired vasodilatation capacity and prevalence of vasoconstriction, maintain inflammatory infiltration of the plaque, impair the strength of the fibrous cap and facilitate aggregation and coagulation. Effective lowering of plasma cholesterol by pharmacological and non-pharmacological means can revert most of these processes and increase the plaque's mechanical stability within several hours to days. Lipid lowering therapy can therefore decrease the risk of acute coronary events within a very short space of time. Thus a radical decrease in lipid levels, along with modification of other risk factors, may become the cornerstone for treatment of acute coronary syndromes, in addition to being an effective treatment in primary and secondary prevention of coronary heart disease (CHD)., T.

The aim of the present study was to investigate whether enzyme chondroitinase ABC (ChABC) treatment influences the phenotype of neural progenitor cells (NPCs) derived from injured rat spinal cord. Adult as well as fetal spinal cords contain a pool of endogenous neural progenitors cells, which play a key role in the neuroregenerative processes follow ing spinal cord injury (SCI) and hold particular promise for therapeutic approaches in CNS injury or neurodegenerative diso rders. In our study we used in vitro model to demonstrate the differentiation potential of NPCs isolated from adult rat spinal cord after SCI, treated with ChABC. The intrathecal delivery of ChABC (10 U/ml) was performed at day 1 and 2 after SCI. The present findings indicate that the impact of SCI resulted in a decrease of all NPCs phenotypes and the ChABC treatment, on the contra ry, caused an opposite effect., L. Slovinská, I. Novotná, D.

A new species Chonopeltis liversedgei sp. n. of the endemic African genus Chonopeltis Thiele, 1900 (Crustacea: Branchiura) is described. T his ectoparasite inhabits the branchial chamber of its mormyrid host Mormyrus lacerda Castelnau, 1861 and was collected from three localities in the Okavango River and its inland Delta in Botswana, Southern Africa.
Tak ako orgánovovaskulárne artériové ischemické choroby (srdcovocievne, cievnocievne, nervovocievne, končatinovocievne, obličkovocievne, pohlavnocievne, pľúcnocievne, črevnocievne, kostnokĺbovosvalovocievne, kožnocievne, očnocievne, ušnocievne, zubnocievne a ďalšie orgánovocievne artériové choroby) aj aortové choroby prispievajú k širokému spektru artériových chorôb: aneuryzmy aorty, akútne aortové syndrómy vrátane aortovej disekcie, intramurálneho hematómu, penetrujúcej aterosklerotickej ulcerácie, ďalej traumatické poškodenie aorty, pseudoaneuryzma, ruptúra aorty, ateroskleróza, vaskulitídy, ako aj genetické choroby (napr. Turnerov syndróm, Marfanov syndróm, Ehlersov‑Danlosov syndróm) a kongenitálne abnormality vrátane koarktácie aorty. Podobne ako iné artériové choroby, aj aortové choroby môžu byť diagnostikované po dlhom časovom období subklinického vývinu alebo sa manifestujú akútne. Akútny aortový syndróm je často prvým znakom choroby, ktorá vyžaduje rýchlu diagnózu, rýchle rozhodnutie a rýchlu akciu k zníženiu extrémne nepriaznivej prognózy. V dokumente sa analyzujú kľúčové klinicko‑etiologicko‑anatomicko‑patofyziologické diagnostické aspekty, klasifikácia a princípy manažmentu aortových chorôb (projekt CIEVY)., In addition to organovascular arterial ischemic diseases (cardiovascular, angiovascular, neurovascular, limbovascular, renovascular, genitovascular, bronchopulmonarovascular, mesenteriointestinokolonovascular, osteoarthromusculovascular, dermovascular, oculovascular, otovascular, stomatovascular, etc.), aortic diseases contribute to the wide spectrum of arterial diseases: aortic aneurysms (AA), acute aortic syndromes (AAS) including aortic dissection (AD), intramural hematoma (IMH), penetrating atherosclerotic ulcer (PAU) and traumatic aortic injury (TAI), pseudoaneurysm, aortic rupture, atherosclerosis, vasculitis as well as genetic diseases (e. g. Turner syndrome, Marfan syndrome, Ehlers‑Danlos syndrome) and congenital abnormalities including coarctation of the aorta (CoA). Similarly to other arterial diseases, aortic diseases may be diagnosed after a long period of subclinical development or they may have an acute presentation. Acute aortic syndrome is often the first sign of the disease, which needs rapid diagnosis and decision making to overcome the extremely poor prognosis. Key clinical‑etiology‑anatomy‑pathophysiology (CEAP) diagnostic aspects and principles of aortic disease management are discussed in this document (the Vessels project)., and Gavorník P., Dukát A., Gašpar Ľ., Medová D., Čaprnda M.
