Coccidioidomycosis is usually acquired by inhalation of spores of Coccidioides immitis and C. posadasii. The disease ranges from a self-limited acute pneumonia (Valley Fever) to a disseminated disease. We present a 44-year-old healthy male who had patchy hair loss of several months duration resembling discoid lupus. He developed a firm non-scaly red plaque on the right forehead. Initial biopsy showed spongiotic dermatitis, and he was treated with systemic steroids. He then developed forehead and periorbital cellulitis and was treated with systemic antibiotics...

Solid organ transplant (SOT) recipients are especially at risk of developing infections by multidrug resistant (MDR) Gram-negative bacilli (GNB), as they are frequently exposed to antibiotics and the healthcare setting, and are regulary subject to invasive procedures. Nevertheless, no recommendations concerning prevention and treatment are available. A panel of experts revised the available evidence; this document summarizes their recommendations: (1) it is important to characterize the isolate's phenotypic and genotypic resistance profile; (2) overall, donor colonization should not constitute a contraindication to transplantation, although active infected kidney and lung grafts should be avoided; (3) recipient colonization is associated with an increased risk of infection, but is not a contraindication to transplantation; (4) different surgical prophylaxis regimens are not recommended for patients colonized with carbapenem-resistant GNB; (5) timely detection of carriers, contact isolation precautions, hand hygiene compliance and antibiotic control policies are important preventive measures; (6) there is not sufficient data to recommend intestinal decolonization; (7) colonized lung transplant recipients could benefit from prophylactic inhaled antibiotics, specially for Pseudomonas aeruginosa; (8) colonized SOT recipients should receive an empirical treatment which includes active antibiotics, and directed therapy should be adjusted according to susceptibility study results and the severity of the infection...

The use of oxygen-driven aerosol inhalation therapy with budesonide (suspension) and terbutaline sulfate for the treatment of pediatric asthmatic bronchitis was studied. Sixty pediatric patients diagnosed with asthmatic bronchitis in Xuzhou Children's Hospital during the period comprising April 2013 to December 2015 were enrolled in the study. After randomly dividing the patients into a control (conventional dexamethasone drip) and a treatment group (inhalation of budesonide with terbutaline sulfate) of 30 patients each, the symptoms were treated using antibiotics when necessary...

Multidrug-resistant organisms are creating a challenge for physicians treating the critically ill. As new antibiotics lag behind the emergence of worsening resistance, intensivists in countries with high rates of extensively drug-resistant bacteria are turning to inhaled antibiotics as adjunctive therapy. These drugs can provide high concentrations of drug in the lung that could not be achieved with intravenous antibiotics without significant systemic toxicity. This article summarizes current evidence describing the use of inhaled antibiotics for the treatment of bacterial ventilator-associated pneumonia and ventilator-associated tracheobronchitis...

Inhaled or nebulised antibiotics are a major topic of ongoing research interest in reducing exacerbations in bronchiectasis. There are no licenced inhaled or nebulised antibiotics currently in bronchiectasis. Areas covered: Inhaled or nebulised ciprofloxacin as a long-term treatment in bronchiectasis. Expert opinion: Results from the Phase III ongoing trials on inhaled or nebulised ciprofloxacin will be key for the outcome of the drugs but additionally, cost-effectiveness and longer-term studies will be necessary to determine the viability of the drug...

Cystic fibrosis (CF) is a disease caused by a mutation in the cystic fibrosis transmembrane conductance regulator protein in the epithelial membrane, and affects at least 30,000 people in the USA. There are between 900 and 1000 new cases diagnosed every year. Traditionally, CF has been treated symptomatically with pancreatic enzymes, bronchodilators, hypertonic saline, and pulmozyme. In July 2015, the US Food and Drug Administration approved Orkambi (lumacaftor/ivacaftor), a combination drug that works on reversing the effects of the defective cystic fibrosis transmembrane conductance regulator protein...

A 2-year-old male mongrel dog was presented because of the onset of dry cough. About 16 hours before, the dog had been exposed to the pesticide that the owner was spraying in the vineyard. Approximately 3 hours later an acute respiratory failure, with a rapid evolution, began. Hemoptysis and regenerative normocytic normochromic anemia arose within hours, and a pulmonary hemorrhage was diagnosed. Pulmonary hemorrhage fast led to pneumonia, as evidenced by the serial CXR findings and the developing of leukocytosis...

Despite aggressive antibiotic therapy, bronchopulmonary colonization by Pseudomonas aeruginosa causes persistent morbidity and mortality in cystic fibrosis (CF). Chronic P. aeruginosa infection in the CF lung is associated with structured, antibiotic-tolerant bacterial aggregates known as biofilms. We have demonstrated the effects of non-bactericidal, low-dose nitric oxide (NO), a signaling molecule that induces biofilm dispersal, as a novel adjunctive therapy for P. aeruginosa biofilm infection in CF in an ex vivo model and a proof-of-concept double-blind clinical trial...

Positive experience with inhaled antibiotics in pulmonary infections of patients with cystic fibrosis has paved the way for their utilization in mechanically ventilated, critically ill patients with lower respiratory tract infections. A successful antibiotic delivery depends upon the size of the generated particle and the elimination of drug impaction in the large airways and the ventilator circuit. Generated droplet size is mainly affected by the type of the nebulizer employed. Currently, jet, ultrasonic, and vibrating mesh nebulizers are marketed; the latter can deliver optimal antibiotic particle size...

BACKGROUND: Childhood asthma is a substantial health burden in Thailand. Due to a lack of pediatric respiratory specialists (pediatric pulmonologists and allergists; RS), most Thai children are cared for by general pediatricians (pediatric primary care providers (PCP)). OBJECTIVES: We investigated whether current practices of Thai pediatricians complied with asthma guidelines and compared practices (diagnosis and treatments) provided by PCP and RS. METHODS: A cross-sectional study was conducted using electronic surveys including four case scenarios of different asthma phenotypes distributed to Thai pediatricians...

Bacillus anthracis is considered a likely agent to be used as a bioweapon and use of a strain resistance to the first-line antimicrobial treatments is a concern. We determined treatment efficacy against a ciprofloxacin-resistant (C(r)) strain of B. anthracis (C(r) Ames) in a murine inhalational anthrax model. Ten groups of 46 BALB/c mice were exposed by inhalation to 7-35 LD50 of B. anthracis C(r) Ames spores. Commencing at 36 hours (h) post-exposure, groups were administered intraperitoneal doses of sterile water for injections (SWI) and ciprofloxacinalone (control groups), or ciprofloxacin combined with two antimicrobials including meropenem/linezolid, meropenem/clindamycin, meropenem/rifampin, meropenem/doxycycline, penicillin/linezolid, penicillin/doxycycline, rifampin/linezolid, or rifampin/clindamycin at appropriate dosing intervals(6 or 12 hours) for the respective antibiotics...

BACKGROUND: Exacerbations of asthma cause a substantial global illness burden. Adults with uncontrolled persistent asthma despite maintenance treatment require additional therapy. Since macrolide antibiotics can be used to treat persistent asthma, we aimed to assess the efficacy and safety of oral azithromycin as add-on therapy in patients with uncontrolled persistent asthma on medium-to-high dose inhaled corticosteroids plus a long-acting bronchodilator. METHODS: We did a randomised, double-blind, placebo controlled parallel group trial to determine whether oral azithromycin decreases the frequency of asthma exacerbations in adults (≥18 years) with symptomatic asthma despite current use of inhaled corticosteroid and long-acting bronchodilator, and who had no hearing impairment or abnormal prolongation of the corrected QT interval...

This article summarizes the top 20 original research studies and four practice guidelines of 2016, based on regular literature surveillance and as selected by members of the Canadian Medical Association. The studies, known as POEMs (patient-oriented evidence that matters), were rated highly because of their relevance, validity, and potential to change practice. Key hypertension treatment findings include reduced mortality (a benefit not demonstrated in lower-risk persons or persons with diabetes mellitus) but also an increase in harms with a more aggressive blood pressure target in high-risk persons with hypertension and without diabetes...

Burkholderia cepacia complex (Bcc) infection, associated with cystic fibrosis (CF) is intrinsically multidrug resistant to antibiotic treatment making eradication from the CF lung virtually impossible. Infection with Bcc leads to a rapid decline in lung function and is often a contraindication for lung transplant, significantly influencing morbidity and mortality associated with CF disease. Standard treatment frequently involves antibiotic combination therapy. However, no formal strategy has been adopted in clinical practice to guide successful eradication...

Pulmonary fibrosis is a form of lung disease that develops due to aberrant wound-healing following repeated alveoli injury in genetically susceptible individuals, resulting in chronic inflammation, excess deposition of the extracellular matrix components, mainly collagen, and scarring of lung tissue. In addition to irradiation, environmental agents such occupational inhalants, and chemotherapeutic agents, microbial agents also play a role in the etiology of the disease. While viruses have received the most attention, emerging evidence suggest that bacteria and fungi also play a part in the etiology of pulmonary fibrosis...

Silver has attracted a lot of attention as a powerful, broad spectrum and natural antimicrobial agent since the ancient times because of its non-toxic nature to the human body at low concentrations. It has been used in treatment of various infections and ulcers, storage of water, and prevention of bacterial growth on the surfaces and within materials. However there are numerous medical and health benefits of colloidal or nano silver apart from its microbicidal ability which as yet have not been fully embraced by the medical community...
