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...

Mycoplasma pneumoniae (M. pneumoniae) is an important pathogen of neonatal acquired pneumonia in newborns. Rapid and accurate diagnosis of M. pneumoniae infection is critical because timely antibiotic therapy can reduce drug overuse and prevent the development of bacterial resistance. Anti-M. pneumoniae immunoglobulin M (IgM) is an indicator of early infection that can persist for several months. Studies have shown that anti-M. pneumoniae IgA in adults is a reliable indicator of early M. pneumoniae infection...

BACKGROUND: Hypervirulent strain of Klebsiella pneumoniae genotype K1 isolates have recently emerged, causing severe pyogenic liver abscess complicated by devastating metastatic infections in humans. METHODS: We describe a short outbreak of the non-human primate (NHP) research center, associated with a hypervirulent K. pneumoniae. The genetic similarity of the strains was evaluated by pulsed-field gel electrophoresis (PFGE) and multilocus sequence typing (MLST) techniques, and virulence encoding genes were detected by polymerase chain reaction (PCR)...

BACKGROUND: New-onset or worsening heart failure is the most common extra-pulmonary complication of community-acquired pneumonia (CAP) during the first 30 days after diagnosis. METHODS: We evaluated the changes in the right ventricular function amongst adult CAP survivors from the time of acute infection to its resolution. We performed comprehensive transthoracic echocardiographic examinations to assess right heart function during the acute illness and the convalescent period (four to six weeks after hospital discharge)...

OBJECTIVES: The goal of this study is to investigate the immune response to the 13-valent pneumococcal conjugate vaccine (PCV13) in former pneumococcal CAP patients. We hypothesize that an impaired or suboptimal humoral immune response against (specific) pneumococcal serotypes might explain the vulnerability for pneumococcal disease. METHODS: Hospitalised adult CAP patients who participated in two trials (2004-2006 (n=201) and, 2007-2009 (n=304)) were screened. Patients eligible for inclusion had CAP caused by either S...

INTRODUCTION: Respiratory tract infections have been an important cause of morbidity and mortality worldwide that is looming large especially in context of antibiotic resistance that is confronted both by a pulmonologist as well as a general practitioner. A reflection to this trend has been the rising phenomenon of MICs as shown the respiratory pathogens towards conventional antibiotics including macrolides or β lactam/β lactamase inhibitor combinations. Respiratory fluoroquinolones offer broad yet potent cover of respiratory pathogens leading to their obvious choice for empirical therapy for clinical persisters or high risk cases with prior history of antibiotics not-withstanding the clinical concerns in tropical countries...

Coccidioidomycosis is a leading cause of community-acquired pneumonia within its traditional endemic zone in the Southwestern United States and portions of Mexico and Central and South America. Its incidence has increased dramatically within the endemic region; its presence outside of the region, facilitated by a mobile society, is also now substantial. Although only a fraction of the incident disease progresses beyond subclinical illness, this proportion is large in absolute terms and causes substantial disease burden...

Extended-spectrum beta-lactamases (ESBLs), AmpC-type beta-lactamases (ACBLs) and carbapenemases are among the most important resistance mechanisms in Enterobacteriaceae. This study investigated the presence of these resistance mechanisms in consecutive non-replicate isolates of Escherichia coli (n = 2,352), Klebsiella pneumoniae (n = 697), and Proteus mirabilis (n = 275) from an Italian nationwide cross-sectional survey carried out in October 2013. Overall, 15.3% of isolates were non-susceptible to extended-spectrum cephalosporins but susceptible to carbapenems (ESCR-carbaS), while 4...

Streptococcus pneumoniae (S. pneumoniae), otherwise known as 'the pneumococcus', is a fascinating microbe that continues to pose a significant problem to public health. Currently there are no specific National Institute for Clinical Excellence (NICE) or British Thoracic Society (BTS) clinical guidelines referring to the treatment of invasive pneumococcal infection. NICE clinical guidelines suggest the use of lytic β-lactam antibiotic regimens for the management of community-acquired pneumonia and bacterial meningitis; infections for which S...

Pulmonary emphysema is an important radiological finding in chronic obstructive pulmonary disease patients, but bacteriological differences in pneumonia patients according to the severity of emphysematous changes have not been reported. Therefore, we evaluated the bacteriological incidence in the bronchoalveolar lavage fluid (BALF) of pneumonia patients using cultivation and a culture-independent molecular method. Japanese patients with community-acquired pneumonia (83) and healthcare-associated pneumonia (94) between April 2010 and February 2014 were evaluated...

Cor triatriatum sinistrum (CTS) is a congenital anomaly where the left atrium is divided into two compartments by a fibromuscular membrane. This report aims to add to the literature on a rare cardiac condition that can cause neurological morbidity. We report a case of a 19-year-old female with an infarct in the right middle cerebral artery (MCA) territory initially maintained on aspirin. Eighteen months later, she had recurrence of weakness, for which repeat transthoracic echocardiography (TTE) and re-evaluation of the first TTE demonstrated a hyperechoic membrane spanning the width of the left atrium, clinching the diagnosis of CTS...

Pneumocystis pneumonia is a potentially life-threatening pulmonary infection that occurs in immunocompromised individuals and HIV-infected patients with a low CD4 cell count. Trimethoprim-sulfamethoxazole has been used as the first-line agent for treatment, but mutations within dihydropteroate synthase gene render potential resistance to sulfamide. Despite advances of combination antiretroviral therapy (cART), Pneumocystis pneumonia continues to occur in HIV-infected patients with late presentation for cART or virological and immunological failure after receiving cART...

A major clinical impact of A. baumannii is hospital-acquired infections including ventilator-associated pneumonia. The treatment of this pathogen is often difficult due to its innate and acquired resistance to almost all commercially available antibiotics. Infections with carbapenem-associated multidrug resistant A. baumannii is the most problematic. Glutathione is a tripeptide thiol-antioxidant and antibacterial activity of exogenous glutathione was reported in some bacteria. However, clinical relevance and molecular details of the antibacterial activity of glutathione are currently unclear...
