BACKGROUND Children in developing country suffer the highest burden of pneumonia. However, few studies have evaluated associations between poverty and pneumonia. METHODS A prospective population-based study on pneumonia was carried out as part of the Latin America Epidemiological Assessment of Pneumococcus (LEAP study). Chest x-rays were obtained for children one to 35 months old with suspect...

The histopathologic findings in lung tissue are reported from five cases of Philadelphia Legionnaire's Disease and the results are compared to pneumonias caused by other microbial and chemical agents. Histopathology of lung tissue was similar in all cases, despite the fact that death occurred between the fourth and 14th day of clinical illness. The inflammatory response was almost totally limit...

Background Currently accepted classifications of pneumonia include community acquired pneumonia (CAP), healthcareassociated pneumonia (HCAP), hospital-acquired pneumonia (HAP), and ventilator-associated pneumonia (VAP). Previous studies have shown a high rate of patients with HCAP or HAP caused by multidrug-resistant bacteria (MDR). Our aim was to determine the differences in etiology and antib...

conclusions the study showed that hais were more frequent in elderly population predominately with respect to vap and infections by gram-negative pathogens. overall mortally was greater in the elderly group although the odds ratio for death was higher in younger patients and increased with every hai diagnosed. patients and methods retrospective analysis of all hospital-acquired infections (hais...

background and objectives: pneumocystis jirovecii pneumonia (pjp) is a chronic fungal infection that caused by p. ji- rovecii . disease is more prevalent among the hiv-infected patients. the colonization of pneumocystis in human respiratory system is associated with the airway inflammation and obstruction. the current study was conducted to identify the preva- lence of p. jirovecii among the pa...

background: following pulmonary aspiration of gastric contents, a variety of conditions occurs ranging from the acute inflammatory response (aspiration pneumonitis) to an infectious process (aspiration pneumonia). they cause due to the failure of protecting mechanism of airway patency following poisoning toxicity. methods: patients with acute drug poisoning for assessment of aspiration-induced ...

BACKGROUND Traditionally, pneumonia has been classified as either community- or hospital-acquired. Although only limited data are available, health care-associated pneumonia has been recently proposed as a new category of respiratory infection. "Health care-associated pneumonia" refers to pneumonia in patients who have recently been hospitalized, had hemodialysis, or received intravenous chemot...

Building-related illness ranges from mild rhinitis to potentially life-threatening hypersensitivity pneumonitis and legionellosis. Sick-building syndrome, consisting of headache, mucous membrane irritation, and fatigue, may be present in 30% of all office workers. Hypersensitivity pneumonitis, asthma, and legionellosis are less common, and it is difficult from existing studies to estimate the i...
