Endoscopic removal of a chondromatous hamartoma by bronchoscopic electrosurgical snare and argon plasma coagulation
A 31-year-old woman presented with a cough, pain on the left side on deep inspiration, dyspnea, and fever. A chest x-ray showed pneumonic infiltration of the left middle and lower lung and decreased left hemithorax volume. A computed tomography (CT) revealed an occlusion of the left main bronchus by an intraluminal tumour. Bronchoscopic biopsy specimens suggested an endobronchial hamartoma. Therefore, we resected the tumour endobronchially using a bronchoscopic electrosurgical snare and argon plasma coagulation

Only 10%–25% of COPD exacerbations are eosinophilic.Aim: To assess whether eosinophilic COPD exacerbations have better outcomes than non-eosinophilic COPD exacerbations in the ICU.Methods: This retrospective observational cohort study was conducted in a thoracic, surgery-level III respiratory ICU of a tertiary teaching hospital for chest diseases from 2013 to 2014. Subjects previously diagnosed with COPD and who were admitted to the ICU with acute respiratory failure were included. Data were collected electronically from the hospital database. Subjects’ characteristics, complete blood count parameters, neutrophil to lymphocyte ratio (NLR), delta NLR (admission minus discharge), C-reactive protein (CRP) on admission to and discharge from ICU, length of ICU stay, and mortality were recorded. COPD subjects were grouped according to eosinophil levels (>2% or ≤2%) (group 1, eosinophilic; group 2, non-eosinophilic). These groups were compared with the recorded data.Results: Over the study period, 647 eligible COPD subjects were enrolled (62 [40.3% female] in group 1 and 585 [33.5% female] in group 2). Group 2 had significantly higher C-reactive protein, neutrophils, NLR, delta NLR, and hemoglobin, but a lower lymphocyte, monocyte, and platelet count than group 1, on admission to and discharge from the ICU. Median (interquartile range) length of ICU stay and mortality in the ICU in groups 1 and 2 were 4 days (2–7 days) vs 6 days (3–9 days) (P<0.002), and 12.9% vs 24.9% (P<0.034), respectively.Conclusion: COPD exacerbations with acute respiratory failure requiring ICU admission had a better outcome with a peripheral eosinophil level >2%. NLR and peripheral eosinophilia may be helpful indicators for steroid and antibiotic management.Keywords: chronic obstructive pulmonary disease, exacerbation, respiratory failure, intensive care unit, peripheral eosinophili
A family of secreted pathogenesis-related proteins in Candida albicans
Analysing culture supernatants of yeast and hyphal cells of Candida albicans, we found two close homologues of pathogenesis-related (PR-) 1 proteins, Rbe1p and Rbt4p, in the secretome. Due to sequence homology, three additional, yet not characterized open reading frames, ORF19.6200, ORF19.2787 and ORF19.2336, together with RBE1 and RBT4 were assigned to a novel family of CaPRY proteins. In a Delta rbe1/Delta rbt4 deletion strain, genome-wide transcriptional analysis revealed differential transcription of only a limited set of genes implicated in virulence and oxidative stress response. Single deletion of RBE1 or RBT4 in a clinical C. albicans isolate resulted in a moderate but significant attenuation in virulence in a mouse model for disseminated candidiasis. However, a synergistic effect was observed in a Delta rbe1/Delta rbt4 double deletion strain, where virulence was strongly affected. Remarkably, transcription of RBT4 and RBE1 was each upregulated in blastospores of Delta rbe1 or hyphae of Delta rbt4 deletion strains respectively, indicating functional complementation thereby compensating a potential virulence defect in the single deletion strains. Furthermore, the double deletion strain showed increased sensitivity to attack by polymorphonuclear leucocytes. Therefore, the crucial contribution of both C. albicans pathogenesis-related proteins to virulence might be vested in protection against phagocyte attack
Immunization status in chronic obstructive pulmonary disease: A multicenter study from Turkey
OBJECTIVE: The purpose of this study is to detect the prevalence and the
factors associated with influenza and pneumococcal vaccination and
outcomes of vaccination during 2013-2014 season in patients with chronic
obstructive pulmonary disease (COPD) in Turkey.
METHODS: This was a multicenter retrospective cohort study performed in
53 different centers in Turkey.
RESULTS: During the study period, 4968 patients were included. COPD was
staged as GOLD 1-2-3-4 in 9.0\%, 42.8\%, 35.0\%, and 13.2\% of the
patients, respectively. Influenza vaccination rate in the previous year
was 37.9\%; and pneumococcus vaccination rate, at least once during in a
life time, was 13.3\%. Patients with older age, higher level of
education, more severe COPD, and comorbidities, ex-smokers, and patients
residing in urban areas had higher rates of influenza vaccination.
Multivariate logistic regression analysis showed that advanced age,
higher education levels, presence of comorbidities, higher COPD stages,
and exacerbation rates were associated with both influenza and
pneumococcal vaccination. The number of annual physician/outpatient
visits and hospitalizations due to COPD exacerbation was 2.73 +/- 2.85
and 0.92 +/- 1.58 per year, respectively. Patients with older age, lower
education levels, more severe COPD, comorbid diseases, and lower body
mass index and patients who are male and are residing in rural areas and
vaccinated for influenza had significantly higher rates of COPD
exacerbation.
CONCLUSIONS: The rates of influenza and pneumococcal vaccination in COPD
patients were quite low, and the number of annual physician/outpatient
visits and hospitalizations due to COPD exacerbation was high in Turkey.
Advanced age, higher education levels, comorbidities, and higher COPD
stages were associated with both influenza and pneumococcal vaccination
