Clinical characteristics of healthcare-associated pneumonia in a public hospital in a metropolitan area of Japan.
Healthcare-associated pneumonia (HCAP) is a new category that is essential in the present aging society. Knowing the different characteristics and outcomes between patients with HCAP and community-acquired pneumonia (CAP) would help physicians manage and treat HCAP patients. Although HCAP is thought to be heterogeneous in regions, there are no reports from a metropolitan area in Japan. ⋯ Low levels of serum albumin (odds ratio, 0.126; 95% CI, 0.025-0.640; P = 0.012) and high scores in the ADROP (age, dehydration, respiratory failure, orientation, and blood pressure) system (odds ratio, 2.846; 95% CI, 1.449-5.587; P = 0.002) were the risk factors for HCAP mortality. In conclusion, patients with HCAP have different epidemiological characteristics compared with those with CAP in a metropolitan area of Japan. Outcomes and risk factors for mortality of patients with HCAP included poor nutritional status and high severity scores on the pneumonia severity scoring system.

Severe pneumococcal community-acquired pneumonia admitted to medical Tunisian ICU.
Streptococcus pneumoniae is the most common cause of community-acquired pneumonia (CAP). There are no available data about this disease in Tunisian intensive care patients. The objective of this study is to describe the clinical and microbiological features of pneumococcal CAP and determine the prognostic factors. ⋯ The need of mechanical ventilation at admission [odds ratio (OR), 3.4; 95% confidence interval (CI), 1.67-6.94; P = 0.001), Sepsis-related Organ Failure Assessment (SOFA) score at admission ≥4 (OR, 3.1; 95% CI, 1.56-6.13; P = 0.001), and serum creatinine at admission ≥102 μmol/l (OR, 1.8; 95% CI, 1.02-3.17; P = 0.043) were independent factors related to ICU mortality. In conclusion, pneumococcal CAP requiring hospitalization in the ICU is associated with high mortality. All isolated stains were susceptible to penicillin.

Case ReportsNeonatal meningitis caused by Streptococcus gallolyticus subsp. pasteurianus.
We encountered a case of neonatal meningitis caused by Streptococcus gallolyticus subsp. pasteurianus. The patient was an 8-day-old boy. Gram staining of the cerebrospinal fluid (CSF) revealed gram-positive cocci in pairs or in short chains. ⋯ This bacterium was classified as S. gallolyticus subsp. pasteurianus in the latest report in 2003. Since this change, there have only been a few cases of neonatal meningitis caused by this bacterium. Here we report this rare case.

Bactericidal activity of topical antiseptics and their gargles against Bordetella pertussis.
Bordetella pertussis is the etiological agent of whooping cough, a common cause of respiratory illness in both children and adults. In the present study, we investigated the bactericidal activity of four antiseptics-povidone-iodine (PVP-I), benzethonium chloride (BEC), chlorhexidine gluconate (CHG) and benzalkonium chloride (BAC)-against B. pertussis ATCC9797 and clinical isolates. ⋯ However, BEC gargle had low bactericidal activity. Our results indicate that topical PVP-I and BAC, and PVP-I gargle would be useful as effective antiseptics against B. pertussis.

Case ReportsAcute generalized exanthematous pustulosis after ceftriaxone use resembling sepsis.
Acute generalized exanthematous pustulosis is an uncommon disorder, characterized by the acute onset of multiple pruritic, small, nonfollicular, sterile, superficial pustules over erythematous and edematous skin. It is frequently caused by medications, mainly antibiotics, and particularly beta-lactams. ⋯ We report a case of ceftriaxone-induced acute generalized exanthematous pustulosis that presented with the appearance of sepsis. After discontinuation of ceftriaxone, the findings were improved.
