Sven Holger Baum, Christopher Mohr
PURPOSE: The aim of this study was to evaluate which primary tumours metastasize on the head and neck region, identify the kind of clinical manifestation, the types of diagnostics that should be performed, and prove that the therapy appears possible and useful. PATIENTS: As many as 91 patients with a distant metastasis on the head and neck were enrolled in this retrospective clinical study from January 2004 to September 2016. All the patients were evaluated for clinical symptoms, primary tumour, localization, diagnostics, and surgical procedure...

Female, 85 y.o., weighting 60kg, multiple trauma patient. After an initial laparotomy, an emergent thoracotomy was performed using a bronchial blocker for lung isolation (initial active suction was applied). During surgery, bronchial cuff was deflated, causing a self-limited tracheal blood flooding. A second lung isolation was attempted but it was not as effective as initially. Probably, a lung collapse with the same bronchial blocker was impaired in the second attempt because of the obstruction of bronchial blocker lumen by intraoperative endobronchial hemorrhage...

Thymic stromal lymphopoietin (TSLP) is a cytokine released by human lung epithelium in response to external insult. Considered as a master switch in T helper 2 lymphocyte (Th2) mediated responses, TSLP is believed to play a key role in allergic diseases including asthma. The aim of this study was to use a phenotypic approach to identify new biological and chemical starting points for inhibition of TSLP production in human bronchial epithelial cells (NHBE), with the objective of reducing Th2-mediated airway inflammation...

Background: Patients with lung cancer undergoing surgical and medical treatment are at increased risk for pulmonary complications. The importance of routine bronchoscopy procedure in populations with lung cancer has rarely been defined. We aimed to determine the growth of potentially pathogenic microorganisms (PPM) among patients evaluated by bronchoscopy for lung cancer. Methods: This prospective study included 155 consecutive patients with lung mass or radiologic findings suspicious for malignancy...

Background: Endoscopic lung volume reduction (eLVR) is a therapeutic option for selected patients with COPD and severe emphysema. Infectious exacerbations are serious events in these vulnerable patients; hence, prophylactic antibiotics are often prescribed postinterventionally. However, data on the microbiological airway colonization at the time of eLVR are scarce, and there are no evidence-based recommendations regarding a rational antibiotic regimen. Objective: The aim of this study was to perform a clinical and microbiological analysis of COPD patients with advanced emphysema undergoing eLVR with endobronchial valves at a single German University hospital, 2012-2017...

BACKGROUND Intrapulmonary carcinoid tumors (ICTs) are malignant, slow-growing tumors classified as either: i) typical, less aggressive, well-differentiated tumors or ii) atypical, more aggressive, poorly-differentiated tumors. Most typical carcinoid tumors originate in the central airway and present with symptoms related to bronchial obstruction. In contrast, atypical carcinoids tend to occur more peripherally and are generally detected incidentally as a solitary pulmonary nodule (SPN). Typical carcinoid tumors usually do not exhibit increased metabolic activity on positron emission tomography with 18-fuorine-fluorodeoxyglucose (FDG PET) as would be expected for malignant tumors...

The human respiratory system is highly prone to diseases and complications. Many lung diseases, including lung cancer (LC), tuberculosis (TB), and chronic obstructive pulmonary disease (COPD) have been among the most common causes of death worldwide. Cystic fibrosis (CF), the most common genetic disease in Caucasians, has adverse impacts on the lungs. Bronchial proteomics plays a significant role in understanding the underlying mechanisms and pathogenicity of lung diseases and provides insights for biomarker and therapeutic target discoveries...

A 15 year old girl presented with complaints of prolonged fever and recurrent episodes of hemoptysis. Initial investigation showed pancytopenia and radiological imaging was suggestive of necrotizing pneumonia. Subsequently, mucor was isolated from bronchoalveolar lavage fluid, but even on appropriate medications her condition kept deteriorating. She had multiple bouts of hemoptysis and a repeat imaging of chest showed dissemination of mucormycosis to pulmonary vein and heart. Bone marrow biopsy identified acute lymphoblastic leukemia (ALL) as the cause of pancytopenia...

Bordetella pertussis isolation by culture has low detection sensitivity for diagnosing pertussis; the diagnosis is confirmed by measuring serum anti-pertussis toxin (anti-PT) or anti-filamentous hemagglutinin antibody titers, and by genetic testing (polymerase chain reaction/loop-mediated isothermal amplification). Isolation of B. pertussis in adults is difficult, resulting in a delayed diagnosis, as a delayed cough may present ≥3 months after onset. Differentiation from bronchial asthma is also important...

BACKGROUND: Bronchial fibroblasts are the main structural cells responsible for extracellular matrix production and turnover in lung tissue. They play a key role in airway remodelling in asthma through different cytokines including interleukin (IL-6). OBJECTIVE: To decipher IL-6 signalling in bronchial fibroblasts obtained from severe eosinophilic asthmatics compared to mild asthmatics and healthy controls. METHODS: Human bronchial fibroblasts were isolated from bronchial biopsies of mild and severe eosinophilic asthmatics and non-atopic healthy controls...

The combined course of bronchial asthma (BA) and digestive system pathology is one of the most frequent, severe and clinically varied pathology. The purpose of the paper - to study the influence of gastroesophageal reflux disease (GERD) on the course of BA and the effectiveness of antireflux therapy in combined pathology. Patients with combined pathology were treated in full-time department more frequently than patients with isolated BA (3,4±0,5 per year to - 1,8±0,3; р<0,05). The statistically reliable correlation between frequency of heartburn and frequency of cough, which goes over to asthma attacks was observed (r=0,59; р<0,05)...

Background: Colistin-resistant Pseudomonas aeruginosa (P. aeruginosa) has been defined as pandrug-resistant (PDR) strain. Outbreaks of PDR P. aeruginosa especially in pulmonary tract infections due to contaminated bronchoscopes have rarely been reported. The emergence of pandrug-resistant strains in both CF (Cystic Fibrosis) and non-CF clinical isolates over recent years remains of a great concern. Hospital wards contaminated with PDR P. aeruginosa infection, must be shot down until their eradication...

Human coronaviruses (HCoVs) enter cells via two distinct pathways: the endosomal pathway using cathepsins to activate spike protein and the cell-surface or early endosome pathway using extracellular proteases such as transmembrane protease serine 2 (TMPRSS2). We previously reported that clinical isolates of HCoV-229E preferred cell-surface TMPRSS2 to endosomal cathepsin for cell entry, and that they acquired the ability to use cathepsin L by repeated passage in cultured cells and were then able to enter cells via the endosomal pathway...

BACKGROUND: Bronchial epithelial cells (BEC) are primary target for Rhinovirus infection through attaching to cell membrane proteins. OM-85, a bacterial extract, improves recovery of asthma and COPD patients after viral infections, but only part of the mechanism was addressed, by focusing on defined immune cells. OBJECTIVE: We therefore determined the effect of OM-85 on isolated primary human BEC of controls (n = 8), asthma patients (n = 10) and COPD patients (n = 9)...

We investigated the effects of different selective α2 -adrenergic receptor (AR) agonists (detomidine, medetomidine, xylazine, and brimonidine) on the contractions of horse-isolated bronchi induced by electrical field stimulation (EFS) and by carbachol. No effects were observed on the contraction induced by carbachol, while α2 -AR agonists reduced EFS-evoked contractions in a concentration-related fashion. The rank order of potency (pD2 ) was brimonidine (7.40 ± 0.20) >medetomidine (7.09 ± 0.24) >detomidine (6...

Neisseria meningitidis (meningococcus) can cause meningococcal disease, a rapidly progressing and often fatal disease that can occur in previously healthy children. Meningococci are found in healthy carriers, where they reside in the nasopharynx as commensals. While carriage is relatively common, invasive disease, associated with hypervirulent strains, is a comparatively rare event. The basis of increased virulence in some strains is not well understood. New Zealand suffered a protracted meningococcal disease epidemic, from 1991 to 2008...

Rothia mucilaginosa (R. mucilaginosa), formerly named Stomatococcus mucilaginosus, is a facultatively anaerobic, encapsulated gram-positive coccus, which forms part of the normal oropharyngeal and is rarely considered to be a pathogen in immunocompetent patients, although it can produce, on rare occasions, serious infections like bacteremia, endocarditis and respiratory infections; such as pneumonia, pleural empyema or superinfection of bronchiectasis. We present the case of a 74-year-old male diagnosed with right basal pneumonia of torpid evolution with a poor initial response to different antibiotics, with clinical and radiological worsening and the appearance of bilateral bronchopneumonia with pseudonodular images...
