Pseudomonas aeruginosa lung infection is a main cause of disability and mortality worldwide. Acute inflammation and its timely resolution are crucial for ensuring bacterial clearance and limiting tissue damage. Here, we investigated protective actions of resolvin (Rv) D1 in lung infection induced by the RP73 clinical strain of P. aeruginosa. RvD1 significantly diminished bacterial growth and neutrophil infiltration during acute pneumonia caused by RP73. Inoculum of RP73, immobilized in agar beads, resulted in persistent lung infection up to 21 days, leading to a non resolving inflammation reminiscent of human pathology...

BACKGROUND Chronic Granulomatous Disease (CGD) is a rare immunodeficiency disease caused by a genetic defect in the NADPH (nicotinamide adenine dinucleotide phosphate) oxidase enzyme, resulting in increased susceptibility to bacterial and fungal infections. The inheritance can be X-linked or autosomal recessive. Patients usually present with repeated infections early in life. We present an unusual case of a 23-year-old patient diagnosed with CGD. CASE REPORT A 23-year-old white woman with no previous history of recurrent infections presented with complaints of fever, shortness of breath, and diffuse myalgia...

Levetiracetam is widely regarded as a benign antiepileptic drug, compared to older antiepileptic medication. We report a case of eosinophilic pneumonia due to levetiracetam use in a non-smoking woman aged 59 years with no previous respiratory history. Our patient presented with exertional breathlessness and marked desaturation on exertion. She displayed 'reverse bat-wing' infiltrates on her chest radiograph and peripheral eosinophilia on a complete blood count. Her symptoms, radiology and peripheral eosinophilia resolved completely with cessation of levetiracetam and a course of prednisolone...

BACKGROUND: The current recommendation within integrated Community Case Management guidelines that all children presenting with uncomplicated fever and no danger signs be followed up after three days may not be necessary. Such fevers often resolve rapidly (usually within 48-96 h), and previous studies suggest that expectant home care for uncomplicated fever can be safely recommended. We aim to determine the non-inferiority of a conditional versus a universal follow-up visit for these children...

REVIEW

Legionella pneumophila is an etiological agent of the severe pneumonia known as Legionnaires' disease (LD). This gram-negative bacterium is thought to replicate naturally in various freshwater amoebae, but also replicates in human alveolar macrophages. Inside host cells, legionella induce the production of non-endosomal replicative phagosomes by injecting effector proteins into the cytosol. Innate immune responses are first line defenses against legionella during early phases of infection, and distinguish between legionella and host cells using germline-encoded pattern recognition receptors such as Toll-like receptors , NOD-like receptors, and RIG-I-like receptors, which sense pathogen-associated molecular patterns that are absent in host cells...

Infection with Burkholderia cepacia complex (Bcc) bacteria is a threat to cystic fibrosis (CF) patients, commonly leading to a fatal pneumonia, the cepacia syndrome. It causes a massive production of pro-inflammatory cytokines and leucocyte recruitment to airway epithelium without resolving infection and contributing to tissue lesion. To dissect how Bcc bacteria subvert the immune response, we developed a co-culture model with human dendritic cells (DCs) and B. cenocepacia clonal variants isolated from a chronically infected CF patient, who died with cepacia syndrome...

Solithromycin is a novel fluoroketolide developed in both oral and intravenous formulations to address increasing macrolide resistance in pathogens causing community-acquired bacterial pneumonia (CABP). When compared with its macrolide and ketolide predecessors, solithromycin has several structural modifications which increase its ribosomal binding and reduce its propensity to known macrolide resistance mechanisms. Solithromycin, like telithromycin, affects 50S ribosomal subunit formation and function, as well as causing frame-shift errors during translation...

The minimal genome of the mollicute Mycoplasma hyopneumoniae, the etiological agent of porcine enzootic pneumonia, encodes a limited repertoire of antioxidant enzymes that include a single and atypical peroxiredoxin (MhPrx), whose evolution and function were studied here. MhPrx has only one catalytic cysteine, in contrast with some of its possible ancestors (2-Cys peroxiredoxins), which have two. Although it is more similar to 2-Cys orthologs, MhPrx can still function with a single peroxidatic cysteine (CysP), using non-thiolic electron donors to reduce it...

Systemic vasculitis involving the lung is a rare manifestation of myelodysplastic syndrome (MDS), and secondary vasculitis is considered to have poor prognosis. A 44-year-old man presented with fever and dyspnea of 1 month duration. A chest radiograph revealed bilateral multiple wedge shaped consolidations. In addition, the results of a percutaneous needle biopsy for non-resolving pneumonia were compatible with pulmonary vasculitis. Bone marrow biopsy was performed due to the persistence of unexplained anemia and the patient was diagnosed with MDS...

Respiratory tract infections are among the most frequent infections in humans causing millions of deaths especially in children and the elderly. Antibiotics and vaccines are the main available tools of control, but resistant strains are continuously arising and available vaccines only account for few of many pathogens involved. Non-specific immunotherapies are an emerging alternative to induce protective immunity at the airways. Mucosally administered polyvalent bacterial lysates (PBLs) have been widely used for decades for prevention of respiratory diseases, but the bases of their proposed therapeutic effectiveness are still controversial...

The role of radial-endobronchial ultrasound (R-EBUS) assisted transbronchial biopsy (TBB) for the diagnosis of peripheral pulmonary lesions is well established. However, no study has addressed its safety and value in hemato-oncological patients presenting with non-resolving infiltrates during persistent febrile neutropenia. To assess safety and feasibility of R-EBUS assisted TBB in severe thrombocytopenic and neutropenic patients. Over a period of 18 months, eight patients were assessed with R-EBUS assisted TBB after adequate platelet transfusion...

The principal aim of this review is to present the current knowledge regarding acute otitis media (AOM) with spontaneous tympanic membrane perforation (STMP) and to address the question of whether AOM with STMP is a disease with specific characteristics or a severe case of AOM. PubMed was used to search for all studies published over the past 15 years using the key words "acute otitis media" and "othorrea" or "spontaneous tympanic membrane perforation". More than 250 articles were found, but only those published in English and providing data on aspects related to perforation of infectious origin were considered...

Streptococcus pneumoniae typically express one of 92 serologically distinct capsule polysaccharide (cps) types (serotypes). Some of these serotypes are closely related to each other; using the commercially available typing antisera, these are assigned to common serogroups containing types that show cross-reactivity. In this serotyping scheme, factor antisera are used to allocate serotypes within a serogroup, based on patterns of reactions. This serotyping method is technically demanding, requires considerable experience and the reading of the results can be subjective...

BACKGROUND: Head and neck cancer treatment has developed over the last decade, with improved mortality and survival rates, but the treatments often result in dysphagia (a difficulty in swallowing) as a side effect. This may be acute, resolving after treatment, or remain as a long-term negative sequela of head and neck cancer (HNC) treatment. Interventions to counteract the problems associated with dysphagia include swallowing exercises or modification of diet (bolus texture, size), or both...
