PURPOSE: To evaluate the efficacy of an early bronchoalveolar lavage (E-BAL) protocol. BAL was performed within 48 h for intubated patients with traumatic brain injury or chest trauma. We hypothesized that E-BAL would decrease antibiotic use and improve outcomes compared to late BAL (L-BAL) triggered by clinical signs of pneumonia. METHODS: Retrospective cohort analysis of 132 patients with quantitative BAL and ≥1 risk factor: head Abbreviated Injury Score ≥2, ≥3 rib fractures, or radiographic signs of aspiration or pulmonary contusion...

OBJECTIVE: A large number of population in both developing and developed countries are affected by bronchitis, among all the factors, bacterial infection was considered as a critical cause of acute exacerbations of chronic bronchitis. Although several anti-bacterial agents were proved to have the effect of alleviating bronchitis, their relative efficacies and potential side effects remained not clear. We are keen to compare the pathogen eradication rate and safety of anti-bacterial agents for bronchitis...

Persistent mechanical or functional dysphagia is the most common clinical indication for endoscopic gastrostomy (PEG), however less common conditions may justify prolonged enteral feeding to avoid malnutrition and prevent aspiration. The authors report the case of a 76 year old man referred to the artificial feeding outpatient clinic presenting dysphagia, malnutrition and several episodes of aspiration pneumonia. Upper endoscopy showed a giant esophageal diverticulum, ineffective peristalsis and transient lumen narrowing...

Evidences on diagnosis of tuberculosis (TB) following the World Health Organization (WHO) criteria in children with severe acute malnutrition (SAM) are lacking. We sought to evaluate the WHO criteria for the diagnosis of TB in such children. In this prospective study, we enrolled SAM children aged <5 with radiological pneumonia. We collected induced sputum and gastric lavage for smear microscopy, mycobacterial culture, and Xpert MTB/RIF. Using the last 2 methods as the gold standard, we determined sensitivity, specificity, and positive and negative predictive values of WHO criteria (n = 388)...

The Gram-positive bacterium Streptococcus pneumoniae causes severe disease globally. Vaccines that prevent S. pneumoniae infections induce antibodies against epitopes within the bacterial capsular polysaccharide (CPS). A better immunological understanding of the epitopes that protect from bacterial infection requires defined oligosaccharides obtained by total synthesis. The key to the synthesis of the S. pneumoniae serotype 12F CPS hexasaccharide repeating unit that is not contained in currently used glycoconjugate vaccines is the assembly of the trisaccharide β-D-GalpNAc-(1→4)-[α-D-Glcp-(1→3)]-β-D-ManpNAcA, in which the branching points are equipped with orthogonal protecting groups...

Margaret M McGovern, Ruzan Avetisyan, Bernd-Jan Sanson, Olivier Lidove
Acid sphingomyelinase deficiency (ASMD), a rare lysosomal storage disease, is an autosomal recessive genetic disorder caused by different SMPD1 mutations. Historically, ASMD has been classified as Niemann-Pick disease (NPD) types A (NPD A) and B (NPD B). NPD A is associated with a uniformly devastating disease course, with rapidly progressing psychomotor degeneration, leading to death typically by the age of 3 years, most often from respiratory failure. In contrast, the clinical phenotype and life expectancy of patients with NPD B may vary widely...

Pediatric Pneumonia is one of the principal causes of death by year on children under the age of five worldwide. The diagnosis is commonly made by clinical criteria with support from imaging tools like radiography. Lung ultrasound has been considered a low-cost and portable alternative for pneumonia imaging; however, interpretation is subjective and requires adequate training. In the present work, a pneumonia detection algorithm based on the measurement of the fundamental bandwidth downshift over depth of ultrasound radiofrequency (RF) signals is presented...

Human adenovirus 7 (HAdV-7) strains are a major cause of acute respiratory disease (ARD) among adults and children, associated with fatal pneumonia. An ARD outbreak caused by HAdV-7 that involved 739 college students was reported in this article. To better understand the underlying cause of this large-scale epidemic, virus strains were isolated from infected patients and sequence variations of the whole genome sequence were detected. Evolutionary trees and alignment results indicated that the major capsid protein genes hexon and fibre were strongly conserved among serotype 7 strains in China at that time...

BACKGROUND AND OBJECTIVE: Mortality after hospitalization with community-acquired pneumonia (CAP) is high, compared with age-matched controls. Available evidence suggests a strong link with cardiovascular disease. Our aim was to explore the prognostic value of high-sensitivity cardiac troponin T (cTnT) for mortality in patients hospitalized with CAP. METHODS: CTnT level on admission was measured (assay conducted in 2015) in 295 patients hospitalized with CAP who participated in a randomized placebo-controlled double-blind trial on adjunctive dexamethasone treatment...

The Philippines is a low middle-income, tropical country in Southeast Asia. Infectious diseases remain the main causes of morbidity, including tuberculosis. AIDS/HIV prevalence is still low at <1%, but is rapidly increasing. Fungal disease surveillance has not been done, and its burden has never been estimated. This becomes more important as the population of immunocompromised patients increases, drawn from patients with AIDS, TB, malignancies, and autoimmune diseases requiring chronic steroid use. Using the methodology of the LIFE program ( www...

REVIEW
Nicola Principi, Susanna Esposito
Community-acquired pneumonia (CAP) is an infectious disease caused by bacteria, viruses, or a combination of these infectious agents. The severity of the clinical manifestations of CAP varies significantly. Consequently, both the differentiation of viral from bacterial CAP cases and the accurate assessment and prediction of disease severity are critical for effectively managing individuals with CAP. To solve questionable cases, several biomarkers indicating the etiology and severity of CAP have been studied...

Dystrophic calcification of hilar lymph nodes is a common response to chronic inflammation related to several etiologies and rarely is associated with any clinical findings. A clinical scenario related to these calcified lymph nodes can thus be delayed by the low clinical suspicion associated with such a presumably innocuous finding. Normal respiratory movements however, can cause erosion into adjacent bronchi leading to a broncholith, complications of which can result in morbidity. We illustrate one of these complications, a partial obstruction with subsequent recurrent infection due to normal oral flora - actinomyces...
