In this study, the efficacy of ceftaroline fosamil was compared with that of cefepime in an experimental rabbit meningitis model against two Gram-negative strains (Escherichia coli QK-9 and Klebsiella pneumoniae 1173687). The penetration of ceftaroline into inflamed and uninflamed meninges was also investigated. Both regimens were bactericidal, but ceftaroline fosamil was significantly superior to cefepime against K. pneumoniae and E. coli in this experimental rabbit meningitis model (P < 0.0007 against K. pneumoniae and P < 0.0016 against E. coli). The penetration of ceftaroline was approximately 15% into inflamed meninges and approximately 3% into uninflamed meninges.

Ceftaroline is a new cephalosporin with bactericidal activity against resistant Gram-positive organisms, including methicillin-resistant Staphylococcus aureus (MRSA) and penicillin-resistant Streptococcus pneumoniae, as well as common Gram-negative organisms. This study tested the prodrug, ceftaroline fosamil, against a penicillin-sensitive and a penicillin-resistant strain of S. pneumoniae in an experimental rabbit meningitis model. The penetration of ceftaroline into inflamed meninges was approximately 14%. Ceftaroline fosamil was slightly superior to ceftriaxone against the penicillin-sensitive strain and significantly superior to the combination of ceftriaxone and vancomycin against the penicillin-resistant strain.

The "Comprehensive ICF Core Set for Chronic Obstructive Pulmonary Diseases (COPD)" is an application of the International Classification of Functioning, Disability and Health (ICF) and represents the typical spectrum of problems in functioning of patients with COPD. The objective of this study was to validate this ICF Core Set from the perspective of physicians. Physicians experienced in COPD treatment were asked about the patients' problems treated by physicians in patients with COPD in a three-round electronic mail survey using the Delphi technique. Responses were linked to the ICF. Seventy-six physicians in 44 countries gave a total of 1330 responses that were linked to 148 different ICF categories. Nine ICF categories were not represented in the Comprehensive ICF Core Set for COPD although at least 75% of the participants have rated them as important. Nineteen concepts were linked to the not yet developed ICF component personal factors and seventeen concepts were not covered by the ICF. The high percentage of ICF categories represented in the ICF Core Set for COPD indicates satisfactory content validity from the perspective of the physicians. However, some issues were raised that were not covered and need to be investigated further.

Wir berichten über eine 28-jährige Patientin mit Turner-Syndrom und einer Eisenmangelanämie. Der Hämoccult-Test war intermittierend positiv, eine Blutungsquelle konnte in früheren oberen und unteren Endoskopien nicht gefunden werden. Die Kapselendoskopie zeigte multiple vaskuläre Malformationen im Jejunum und Ileum. Insbesondere zeigt unser Fallbeispiel die grosse Bedeutung der Kapselendoskopie zur Lokalisation von okkulten Blutungen im Bereich des Dünndarms. Wir diskutieren die verschiedene diagnostische Möglichkeiten und Therapieoptionen.

We report the case of a 58-years-old soldier with a history of movement related neck pain, weight loss and exercise intolerance. Blood tests presented signs of an inflammatory syndrome. The CT-scan showed extended thickening of the aortic wall characteristic for aortitis. The diagnosis of giant cell arteritis could be histologically confirmed by biopsy of the temporal arteries. Our case report emphasizes the importance of the various imaging modalities. We discuss the different forms of disease evolution and the treatment regimen.

Fire-eater's pneumonitis, caused by aspiration of petroleum, is an infrequent clinical problem in our region. It is an acute inflammatory response of the lungs to the accidental aspiration of hydrocarbons, as shown in our patient. Despite the severe initial clinical und radiological presentation, fire-eater's pneumonitis usually shows a favourable evolution with "restitutio ad integrum". Acute mortality rate is less than 1%. Fire-eater's lung is a medical emergency and needs medical support and surveillance. There is no good evidence that systemic cortico-steroids and antibiotics are effective in the treatment of hydrocarbon aspiration. Concerning chronic lung injury after fire-eater's pneumonitis, there are favorable results from short observational series.

Ceftobiprole medocaril, a new cephalosporin, is highly active against a broad spectrum of Gram-positive and Gram-negative clinical pathogens, including methicillin-resistant Staphylococcus aureus (MRSA) and penicillin-resistant pneumococci. In this study, we tested ceftobiprole against various Gram-negative pathogens in a rabbit meningitis model and determined its penetration into the cerebrospinal fluid (CSF). In this animal model, ceftobiprole produced an antibacterial activity similar to that of cefepime against an Escherichia coli strain, a Klebsiella pneumoniae strain, and a β-lactamase-negative Haemophilus influenzae strain. Against a β-lactamase-positive H. influenzae strain, ceftobiprole was significantly superior. The penetration of ceftobiprole through inflamed meninges reached about 16% of serum levels compared to about 2% of serum levels through uninflamed meninges.

In this study the efficacy of doripenem, a new broad-spectrum carbapenem, was tested against an Escherichia coli strain and a Klebsiella pneumoniae strain in an experimental animal model. The comparator was cefepime monotherapy. The rabbit meningitis model was used in this study and the penetration of doripenem through uninflamed and inflamed meninges was determined. Doripenem, injected three times (75 mg/kg), led to serum peak levels around 100 mg/L and trough levels around 5 mg/L, resulting in a penetration rate of 14% through inflamed meninges and 7% through uninflamed meninges. Against K. pneumoniae, doripenem was slightly but not significantly more efficacious than cefepime over 8 h (5.40 ± 1.37 log(10) cfu/mL versus 3.59 ± 0.89 log(10) cfu/mL for cefepime). Also against the E. coli strain doripenem was slightly superior to the comparator (5.55 ± 0.87 log(10) cfu/mL versus 3.80 ± 1.10 log(10) cfu/mL for cefepime), although the difference was not significant. Doripenem is a potential monotherapy for the treatment of meningitis due to Gram-negative microorganisms.

The objective of this systematic review and content analysis was to identify and quantify the concepts contained in patient-administered health status measures in sleep medicine practice and research using the International Classification of Functioning, Disability and Health (ICF) as a reference. Both generic and condition-specific patient-administered measures/questionnaires used in sleep medicine practice and research were identified and selected. A comprehensive search strategy for reviews, National/International Guidelines and Standard References to ensure that all areas of functioning, disability and health were captured was used. The contents of the selected measures were examined and linked to the ICF using established linking rules. The frequencies of ICF categories covering the concepts contained in the 115 patient-administered measures were used for the descriptive analysis and content comparison. Of these, 35 were of a generic nature, 17 were symptom-related, and 63 condition-specific. The concepts identified in the questionnaires' items were predominantly linked to categories of the ICF component related to body functions (61.4%), followed by activities and participation (15.3%), and then environmental factors (9.8%). The measures vary greatly with regard to the number and specificity of the ICF categories covered, as indicated by the proportional indices of content density and content diversity. The ICF provides a useful reference to identify, quantify and compare the concepts contained in health status measures used in sleep medicine practice and research.

The International Classification of Functioning, Disability and Health (ICF) provides a comprehensive and universally accepted framework to classify changes in functioning related to health conditions. Comprehensive and Brief Core Sets have been defined for various disorders but not for sleep disorders. Such a Core Set would greatly enhance the techniques available to describe the impact of sleep disorders on patients. The overarching purpose of this paper is to report on phase 1 of the international and World Health Organization (WHO) endorsed consensus process in identifying ICF Core Sets for sleep disorders. A formal decision-making and consensus process which integrated evidence gathered from preparatory studies was carried out. Relevant ICF categories were selected by a sample of international experts from different backgrounds using the nominal group technique. Twenty-six experts from 22 countries and different professional backgrounds attended the consensus conference. Altogether 120 second- or third-level ICF categories were included in the Comprehensive ICF Core Set with the following ICF component split: 49 categories from body functions, 8 from body structures, 31 from activities and participation and 32 from environmental factors. The Brief ICF Core Set included a total of 15 second-level categories: 5 body functions (sleep, energy and drive, attention, consciousness, respiration functions); 3 body structures (brain, respiratory system, pharynx); 4 activities and participation (focusing attention, driving, handling stress and other psychological demands, carrying out daily routine); and 3 environmental factors (immediate family; health services, systems, and policies; and health professionals). A formal consensus process integrating evidence and expert opinion led to the first version of the ICF Core Sets for persons with sleep disorders. Further validation of the Core Set is needed.
