We demonstrated that not whole Mycobacterium tuberculosis but its particular antigens, hsp70 Mtb , hsp65 Mtb , and hsp16 Mtb , are present in lymph node tissues of patients with sarcoidosis (SA). hsp16 Mtb occurs in the early stage of SA, whereas hsp70 Mtb occurs in stage II of SA. hsp65 Mtb is highly expressed in the capillary vessels in lymph node tissues in patients with SA.
Introduction Increased expression of thymidylate synthase (TS) is thought to be associated with resistance to TS-targeting drugs, e.g. pemetrexed. Methods TS protein expression (PE) and gene copy number (GCN) were assayed using immunohistchemistry (IHC) and silver in situ hybridization (SISH), respectively, on primary tumors of 189 resected non-small cell lung (NSCLC) patients. Associations with pathological and clinical features and prognosis were explored. Results Median IHC H-score was 220 (range 10–380) on a 0–400 scale; 17% of patients had TS expression ≥300. TS PE expression did not significantly differ by histology and did not significantly associate with DFS or OS, however there was a tendency for increased DFS (p=0.12) and OS (p=0.12) in PE positive (>median) squamous-cell carcinoma (SCC) patients. Median GCN was 2.5 genes/nucleus (range 1.4–9.6); 29% of patients had GCN ≥3, 7% ≥4 and 0.8% amplification. GCN differed by histology (p=0.015); 50% of SCCs having GCN >2.5 versus 32% of adenocarcinomas (ADCs). There was no significant relationship between TS GCN and DFS or OS, however a trend towards better DFS (p=0.18) and OS (p=0.10) with increased GCN in SCCs was observed. TS GCN significantly correlated with PE (r=0.30, p=0.0009). Conclusions TS PE and GCN vary widely in NSCLC and correlate significantly to each other. TS GCN is higher in SCCs, whereas TS PE does not associate with histological subtypes, clinical features or survival. Variability of TS PE and GCN may indicate potential benefit from pemetrexed therapy in selected SCC patients.
Although surgical resection of MFH is the treatment of choice in MFH, the results are unsatisfactory.
StreszczenieCel pracy: Ocena przebiegu okresu pooperacyjnego po wycię-ciu płata płuca w zależności od zastosowanej formy drenażu: drenażu cyfrowego z regulowaną siłą ssania i tradycyjnego drenażu butlowego. Materiał i metody: Pomiędzy czerwcem 2011 r. a styczniem 2012 r. do badania włączono 64 pacjentów poddanych lobektomii w Klinice Chirurgii Klatki Piersiowej Gdańskiego Uniwersytetu Medycznego. Pacjenci byli losowo kwalifikowani do jednej z dwóch grup. W grupie badanej pacjenci w okresie pooperacyjnym drenowani byli przy zastosowaniu drenażu cyfrowego Thopaz Medela. W grupie kontrolnej po zabiegu stosowano klasyczny drenaż dwubutlowy. Dren usuwano przy dobowej objętości nieprzekraczającej 350 ml i braku przecieku powietrza od minimum 6 godzin. Wyniki: Pacjenci grupy badanej i kontrolnej nie różnili się istotnie pomiędzy sobą: średnim wiekiem, wynikami testów czynnościowych, częstością chorób towarzyszących i odsetkiem zabiegów wykonanych z dostępu wideotorakoskopowego. W okresie pooperacyjnym nie stwierdzono istotnych różnic w medianie długości utrzymywania drenażu (Thopaz 4 dni, kontrola 4 dni, p = 0,919). Podobnie, nie stwierdzono różnic w długości hospitalizacji (Thopaz 6 dni, kontrola 5,5 dnia, p = 0,559). Częstość występowania powikłań wynosiła 37%. Najczęstszymi stwierdzanymi powikłaniami były: migotanie przedsionków (19%), niedodma wymagająca odessania wydzieliny (9%) oraz przedłużony przeciek powietrza (8%). W okresie pooperacyjnym nie było zgonów. U pacjentów z grupy Thopaz istotnie rzadziej stwierdzano powikłania (25%) niż w grupie kontrolnej (50%) (p = 0,039). Wnioski: Usuwanie drenażu przy dobowej objętości 350 ml wraz z zastosowaniem lekkiego, przenośnego zestawu drenażu cyfrowego pozwala znacząco obniżyć częstość występowa-nia powikłań po lobektomii. Słowa kluczowe: lobektomia, drenaż opłucnej, powikłania. Kardiochirurgia i Torakochirurgia Polska 2013; 10 (2) 133 THORACIC SURGERY AbstractAim of the study: The aim of the study was to evaluate the impact of implementing a digital chest drainage device with regulated suction during postoperative care following a pulmonary lobectomy. Material and methods: Sixty-four patients who underwent a lobectomy at the Department of Thoracic Surgery of the Medical University of Gdańsk between June 2011 and January 2012 were included in this study. The patients were randomly divided into two groups. During the postoperative period, the patients in the study group received thoracic drainage using digital chest drainage or a conventional glass bottle. The drain was withdrawn when the daily volume did not exceed 350 ml and there was no air leakage for at least 6 hours. Results: The patients from the study and the control groups did not significantly differ with regard to the following parameters: mean age, physiological test results, presence of concomitant diseases, and surgical access to the chest. During the postoperative period, no significant differences in the drainage duration were found (Thopaz: 4 days, controls: 4 days, p = 0.919). Similarly, the period of ...
