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
Transcription factors exert their regulatory potential on RNA polymerase II machinery through a multiprotein complex called Mediator complex or Mediator. The Mediator complex integrates regulatory signals from cell regulatory cascades with the regulation by transcription factors. The Mediator complex consists of 25 subunits in Saccharomyces cerevisiae and 30 or more subunits in multicellular eukaryotes. Mediator subunit 28 (MED28), along with MED30, MED23, MED25 and MED26, belong to presumably evolutionarily new subunits that seem to be absent in unicellular eukaryotes and are likely to have evolved together with multicellularity and cell differentiation. Previously, we have shown that an originally uncharacterized predicted gene, F28F8.5, is the true MED28 orthologue in Caenorhabditis elegans (mdt-28) and showed that it is involved in a spectrum of developmental processes. Here, we studied the proteomic interactome of MDT-28 edited as GFP::MDT-28 using Crispr/Cas9 technology or MDT-28::GFP expressed from extrachromosomal arrays in transgenic C. elegans exploiting the GFPTRAP system and mass spectrometry. The results show that MDT-28 associates with the Head module subunits MDT-6, MDT-8, MDT-11, MDT-17, MDT20, MDT-22, and MDT-30 and the Middle module subunit MDT-14. The analyses also identified additional proteins as preferential MDT-28 interactants, including chromatin-organizing proteins, structural proteins and enzymes. The results provide evidence for MDT-28 engagement in the Mediator Head module and support the possibility of physical (direct or indirect) interaction of MDT-28 with additional proteins, reflecting the transcription-regulating potential of primarily structural and enzymatic proteins at the level of the Mediator complex.
