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...

INTRODUCTION: Peroral endoscopic myotomy (POEM) is a novel intervention for the treatment of achalasia, which combines the advantages of endoscopic access and myotomy. The purpose of this study was to perform a systematic review of the literature to evaluate the efficacy and safety of POEM. METHODS: The systematic review was conducted following the PRISMA guidelines. Evidence-Based Medicine Reviews, Cochrane Central Register of Controlled Trials, Ovid MEDLINE (R) including in-process and non-indexed citations were searched for POEM studies using the keywords: esophageal achalasia, POEM, endoscopy, natural orifice surgery, laparoscopic Heller myotomy (LHM), and related terms...

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...

A 13-year-old boy with a background of Prader-Willi syndrome (PWS) was admitted to the regional paediatric intensive care unit, with community-acquired pneumonia. Despite a week of intravenous antibiotics, resolution of inflammatory markers and resolving consolidation on radiograph, he remained feverish. Fever of unknown origin investigations were negative and he was diagnosed with central thermal dysregulation secondary to hypothalamic dysfunction in PWS. Following a hyperpyrexia period, secondary rhabdomyolysis and renal failure developed...

BACKGROUND: Outcomes of cryoballoon ablation for paroxysmal atrial fibrillation (PAF) have been reported in the Western countries but not in Japan. The CRYO-Japan PMS study was a single-arm, observational, multicenter, prospective study of the 2nd-generation cryoballoon Arctic Front Advance(TM). We evaluated device- and procedure-related complications and clinical outcomes at 6 months. METHODS AND RESULTS: The 616 patients (male, 72%; mean age, 63±11 years) were enrolled from 33 Japanese hospitals...

Actinomycosis is a chronic suppurative infection caused by filamentous Gram-positive bacilli, leading to a purulent discharge due to sulfur granule formation. Thoracic actinomycosis represents around 20% of Actinomyces infections, with endobronchial involvement being fairly uncommon. Pulmonary actinomycosis should be considered in the differential diagnosis of non-resolving lobar pneumonia or a lobar mass suspicious for malignancy on endobronchial biopsy. A case of endobronchial actinomycosis presenting as post-obstructive pneumonia and mimicking right upper lobe endobronchial carcinoma, which was associated with foreign body aspiration, is reported here...

Staphylococcus aureus causes many types of infections, ranging from self-resolving skin infections to severe or fatal pneumonia. Human innate immune cells, called polymorphonuclear leukocytes (PMNs or neutrophils), are essential for defense against S. aureus infections. Neutrophils are the most prominent cell type of the innate immune system and are capable of producing non-specific antimicrobial molecules that are effective at eliminating bacteria. Although significant progress has been made over the past few decades, our knowledge of S...

A 58-year-old man was seen in a specialist respiratory clinic, with non-resolving pneumonia. Various investigations including CT scan, bronchoscopy and CT-guided biopsy were carried out for suspected malignancy but they could not find any evidence of neoplasia or anything else of significance. The lung mass that persisted for years later resolved with a course of steroids, at which point further investigations for alternative differential diagnoses suggested a surprising conclusion.

INTRODUCTION: Surgery for locally advanced lung cancer is carried out following chemoradiotherapy. However, there are no reports clarifying what the effects on the subsequent prognosis are when surgery is carried out in cases with radiation pneumonitis. In this paper, we report on 2 cases of non-small cell lung cancer with Grade 2 radiation pneumonitis after induction chemoradiotherapy, in which we were able to safely perform radical surgery subsequent to the treatment for pneumonia. PRESENTATION OF CASES: Case 1 was a 68-year-old male with a diagnosis of squamous cell lung cancer cT2aN2M0, Stage IIIA...

A patient with Prader-Willi Syndrome was admitted to the ICU with features of recurrent acute gastric dilatation, aspiration pneumonia and a massive pulmonary embolus. He was initially managed with intubation, assisted ventilation, intravenous fluids and anticoagulation. Decompression of the stomach was achieved with a nasogastric tube. After ventilator weaning, he did not tolerate the nasogastric intubation that led to a further episode of aspiration pneumonia as a result of non-resolving gastric dilatation...

Immunotherapy with intravesical bacillus Calmette-Guérin (BCG) is considered the most effective adjuvant to endoscopic resection of bladder urothelial carcinoma in the therapeutic management of non-muscle invasive (NMIBC) at intermediate and high risk of recurrence and progression (pTa - pT1 and high-grade carcinoma in situ, CIS). Despite its proven efficacy, this type of treatment can determine local and systemic side effects of moderate or severe gravity, with the histological diagnosis of epithelioid granulomas in different organs, even in the absence of microbiological positivity of BCG...

BACKGROUND: Systemic therapy is recommended for advanced non-small-cell lung cancer (NSCLC). However, conventional first-line treatment has generated a plateau in response rate of 25% to 35%. Few studies have shown patients benefit from microwave ablation (MWA) in combination with radiotherapy and chemotherapy. This study aims to evaluate safety and efficacy of percutaneous computed tomography-guided MWA as maintenance after first-line treatment for patients with advanced NSCLC. METHODS: Patients with histologically verified NSCLC stage IIIB or IV between January 2010 and March 2014 were involved...

Acremonium spp. cause human superficial infections including mycetoma, onychomycosis and keratitis. There are a few reports of systemic involvement in immunocompromised patients. However, isolated pulmonary infection in otherwise healthy hosts has never been reported in the literature. Herein, we report a 59 year-old diabetic man with non-resolving pneumonia due to Acremonium spp. and provide a consensus review of the published clinical cases of systemic and respiratory tract infections.
