Penumonia

Acute lung injuries due to acute lung infections remain the major cause of mortality. Thus antibiotics with immunomodulatory and anti-inflammatory activities ,regardless of their antibacterial properties, will help to overcome acute lung infection-induced injuries. The macrolide antibiotics have been shown to possess these properties. Clarithromycin has been shown to possess anti-inflammatory properties in chronic inflammatory conditions. So we evaluated the anti-inflammatory effect of clarithromycin treatment in Klebsiella pneumoniae B5055-induced acute lung infection in mice...

Introduction. Antibiotic resistance is an emerging problem among streptococcal species, especially for severe infections. Automated diagnostic systems for antimicrobial susceptibility testing, such as BD Phoenix, is a recently available instruments that makes it possible to obtain results within 12 h. Methods. Antimicrobial susceptibility testing results of the BD Phoenix system were compared to those obtained from Clinical Laboratory Standards Institute (CLSI) disk-diffusion method. Two-hundred different clinical isolates of streptococci were assayed: beta-hemolytic (n=65), viridans (n=87), S...

We evaluated the positive phase period of ImmunoCard Mycoplasma tests. The subjects were 74 penumonia patients (male : 38, female : 36, 17-94 years old) with positive ImmunoCard Mycoplasma tests. ImmunoCard Mycoplasma tests were performed every week for 8 weeks later, then every 4 weeks until negative conversion. The positive phase period was within a week in 30 of 74 patients (40.5%) and within 4 weeks in 52 patients (70.3%). In each generation the positive phase period of the most patients was within a week...

We investigated the usefullness of Binax NOW urine antigen test, an immunochromatographic assay that binds any soluble Streptococcus pneumoniae antigen (C polysaccharide) for the diagnosis of penumoniae form September 2003 to March 2005. We used 372 samples form the patinets with pneumoniae diagnosed for blood or sputum cultuter or gram-stained sputum smear. Out of 24 culture positive specimens, Binax NOW urine antigen test, showed positive in 18 (75%) specimens. The sensitivity of sputum and blood culture was 71...

Intracellular, non capsulated atypical bacteria (Chlamydia pneumoniae, Mycoplasma pneumoniae, Legionella pneumophila) colonise lower airways very often. Atypical bacteria cause acute infection and exacerbation of chronic inflammation of bronchial tree, mainly chronic obstructive pulmonary disease (COPD). They may trigger bronchial asthma and induce asthma exacerbation. These pathogens are often isolated in sputum of patients suffering from asthma and COPD in stable clinical stage, but opinion about eradication of bacteria in this situation is controversial...

The prevalence of Streptococcus pneumoniae (S. pneumoniae) resistant to penicillin is an increasing problem with variable prevalence across the world. In Mexico, some reports inform prevalence as high as 50% of the isolations. S. penumoniae is a germ that produces a wide variety of diseases, although the most serious infections are in respiratory tract and meningitis. Most patients with the infection caused by this microorganism have a good response to the treatment. The cases with bad prognosis and those which are eventually lethal are related to host factors and microbiologic characteristics such as resistance to beta-lactam antibiotics...

A total of 63 HIV/AIDS patients with acute respiratory infections admitted to "Pedro Kouri" Tropical Medicine Institute's hospital from January to August 1997 were studied. 545 samples in all were processed: 153 sputa, 150 hemocultures, 110 pharyngeal exudates, 61 nasal exudates and 63 otic exudates. The correlation of the results from the acridine orange technique, Gram staining and culture was studied. The most frequent bacterial agents causing acute respiratory infections in the group of isolated strains were: Pseudomonas aeruginosa (29...

In an era of dwindling reimbursement and rising healthcare costs, the impact of nurse staffing models on patient outcomes is a key concern. This study used a descriptive comparison design to examine the effects of a change in the staffing model on length of stay, variable cost, patient satisfaction, incidence of urinary tract infection and penumonia, and pain management in bowel resection patients. There were significant differences in the pain management outcomes between the two staffing models. Other patient outcomes were comparable despite decreasing the total number of caregivers on the unit...

The Institute of Medicine reported unacceptably high rates of medical error but did not identify whether this is a growing or a stabilized problem. This study used longitudinal data from all acute care hospitals in Pennsylvania to track rates of acuity-adjusted iatrogenic atelectasis, cardiac complications, complications in general, decubitus ulcers, gangrenous ulcers, falls, hemorrhage, mortality, penumonia, post-procedural infections, treatment complications, and urinary tract infections, from 1994 to 1997...

During the treatment of sick as well as injured and operated patients it was used the therapy according to the clinical experience of doctors and possibility of the choice of some antibiotic. It was used the therapy according to antibiogram whenever it was possible. In the study the results of using of Neloren-antibiotic, linkomicin, produced in "Bosnalijek" Sarajevo, were followed up comparing to the other antibiotics. Neloren effects on Streptococcus pyogenes, Streptococcus penumoniae, S. viridian's, Staphylococcus aureus (resistant on Penicillin), Corynebacterium diphteriae, Bacillus anthracis Bateroides fragilis, Rikecia prowaseki and some dostridiaes...

Chlamydia pneumoniae (CP) is a bacterium that in recent years has been investigated as an etiologic agent for atherosclerosis. It is a ubiquitous microorganism that has been isolated in various regions of the vascular system and its prevalence is about 10% in the patient population. This study involved a group of 43 patients (27 men, 16 women, mean age 68 years) who underwent carotid endarterectomy. About 9.3% of the patients yielded plaques that tested positive for the DNA genome of Chlamydia pneumoniae.
