Acute facial nerve palsy in children: how often is it lyme borreliosis?
Acute facial nerve palsy in children may be caused by infection by Borrelia burgdorferi, but the incidence of facial nerve palsy and the proportion of facial nerve palsy caused by Lyme borreliosis may vary considerably between areas. Furthermore, it is not well known how often facial nerve palsy caused by Lyme borreliosis is associated with meningitis. In this population-based study, children admitted for acute facial nerve palsy to Stavanger University Hospital during 9 y from 1996 to 2004 were investigated by a standard protocol including a lumbar puncture. ⋯ Lymphocytic meningitis was present in all but 1 of the children with facial nerve palsy caused by Lyme borreliosis where a lumbar puncture was performed (n = 73). In this endemic area for Borrelia burgdorferi, acute facial nerve palsy in children was common. The majority of cases were caused by Lyme borreliosis, and nearly all of these were associated with lymphocytic meningitis.

Diagnostic value of soluble CD163 serum levels in patients suspected of meningitis: comparison with CRP and procalcitonin.
The aim of the study was to evaluate and compare the diagnostic value of sCD163 serum levels with CRP and PCT in meningitis and bacterial infection. An observational cohort study was conducted between February 2001 and February 2005. The study population comprised 55 patients suspected of meningitis on admission to a 27-bed infectious disease department at a Danish university hospital. ⋯ However, sCD163 may be helpful in rapid identification of patients with systemic bacterial infection. If used as an adjunct to lumbar puncture, PCT and CRP had very high diagnostic accuracy for distinguishing between bacterial and viral infection in patients with spinal fluid pleocytosis. However, none of the markers was useful as an independent tool for the clinical diagnosis of patients with purulent meningitis.

Role of CD8 lymphocytes and neutrophilic alveolitis in Pneumocystis jiroveci pneumonia.
We described the characteristics of bronchoalveolar inflammatory cells and their correlation with lung injury in patients with Pneumocystis jiroveci pneumonia. We reviewed all cases of patients with Pneumocystis jiroveci pneumonia in newly diagnosed HIV infected patients admitted to a large metropolitan referral hospital during June 2003 to December 2004. ⋯ Although the number patients in this case series is small, our findings suggest that CD8 cells and alveolar neutrophilic inflammation have a role in lung injury in Pneumocystis jiroveci pneumonia. These findings are consistent with data from animal studies.

Pneumocystis jiroveci pneumonia (PCP) in HIV-1-negative patients: a retrospective study 2002-2004.
A retrospective study was conducted to describe risk factors associated with Pneumocystis jiroveci pneumonia (PCP) among HIV-negative patients. During 2002-2004, 50 cases of PCP were identified at Rigshospitalet University Hospital on the basis of histology, PCR and clinical symptoms of PCP. Predisposing conditions included haematological malignancy (72%), inflammatory diseases (14%), solid organ transplantation (6%) and other conditions associated with immunodeficiency (8%). ⋯ The overall mortality attributable to PCP was 14% and was significantly associated with delayed diagnosis and treatment. Among immunocompromized HIV-negative patients, PCP should be particularly suspected in the context of steroid treatment and lymphopenia. Although low CD4 count is associated with a higher risk of PCP, the use of CD4 count as guidance for risk identification or prophylaxis among HIV-negative patients appears insufficient.

Aetiological diagnostics of acute bacterial meningitis in children.
Aetiology of bacterial meningitis (BM) can be confirmed by various microbiological methods. The aim of this study was to assess the role of microbiological methods used for confirmation of BM in children and determine the influence of the aetiological agent, patient age and antibacterial treatment on study results. Over a 5-y period (1998-2002) BM was diagnosed in 90 children at Vilnius University Centre for Paediatrics. ⋯ However, no influence of patient age was found. Microbiological confirmation was achieved in 59% of cases using CSF and/or blood culture and in 78% of cases using all available methods in practice. The most common pathogens of bacterial meningitis were H. influenzae type b, N. meningitidis and S. pneumoniae.
