  abstract  = {Background: Bowen's disease (BD) of the nail unit is associated with human papillomavirus (HPV) infection. Objective: This study aimed to investigate the frequency of high-risk HPV infection, gender, age and digital distribution in this condition. Methods: Biopsy specimens of 3 consecutive cases with periungual BD were investigated for the presence of HPV DNA by in situ hybridization and by polymerase chain reaction (PCR). Furthermore, 74 cases of ungual BD conducted with HPV genotyping as reported in the literature were reviewed. Results: PCR of biopsy specimens revealed in 2 cases infection with HPV-16 and in 1 case with HPV-73. Additionally, in 1 HPV-16-positive case HPV-31/33 was detected by in situ hybridization. In line, review of the literature demonstrated a clear association of HPV-positive BD with high-risk HPV types. Interestingly, age at diagnosis was significantly lower in women. Whereas in both genders the second to fourth fingers on both hands were commonly diseased, only in men the thumbs were also prominently affected. Conclusions: Infection with high-risk HPV types is common in BD of the nail unit suggesting the aetiological cause. Therefore, patients and partners should be closely followed up for digital and genital HPV-associated lesions.},

  abstract  = {Background Infections with polyomavirus BK virus (BKV) are a common cause of renal dysfunction after renal transplantation and may also be harmful in surgical patients with shock. The aim of the present study was to determine the frequency of BKV viremia in critically ill surgical patients with septic or hemorrhagic shock, and, if viremia is detectable, whether viremia may be associated with renal dysfunction. Findings A total of 125 plasma samples from 44 critically ill surgical patients with septic or hemorrhagic shock were tested by real-time polymerase chain reaction (PCR) for BKV DNA during their stay on the intensive care unit (ICU). BKV viremia occurred in four patients, i.e. in three of the septic and in one of the hemorrhagic shock group. There was no association between viremia and renal dysfunction. All positive samples contained a low viral load (< 500 copies/ml). Conclusions Since BK viremia was rarely found and with low viral load only in critically ill surgical patients with shock, it is very unlikely that BK viremia results in BK nephropathy later on.},

  abstract  = {Background: Oligoclonal bands (OCB) are detected in the cerebrospinal fluid (CSF) in more than 95\% of patients with multiple sclerosis (MS) in the Western hemisphere. Here we evaluated the intrathecal, polyspecific antiviral immune response as a potential diagnostic CSF marker for OCB-negative MS patients. Methodology/Principal Findings: We tested 46 OCB-negative German patients with paraclinically well defined, definite MS. Sixteen OCB-negative patients with a clear diagnosis of other autoimmune CNS disorders and 37 neurological patients without evidence for autoimmune CNS inflammation served as control groups. Antibodies against measles, rubella, varicella zoster and herpes simplex virus in paired serum and CSF samples were determined by ELISA, and virus-specific immunoglobulin G antibody indices were calculated. An intrathecal antibody synthesis against at least one neurotropic virus was detected in 8 of 26 (31\%) patients with relapsing-remitting MS, 8 of 12 (67\%) with secondary progressive MS and 5 of 8 (63\%) with primary progressive MS, in 3 of 16 (19\%) CNS autoimmune and 3 of 37 (8\%) non-autoimmune control patients. Antibody synthesis against two or more viruses was found in 11 of 46 (24\%) MS patients but in neither of the two control groups. On average, MS patients with a positive antiviral immune response were older and had a longer disease duration than those without. Conclusion: Determination of the intrathecal, polyspecific antiviral immune response may allow to establish a CSF-supported diagnosis of MS in OCB-negative patients when two or more of the four virus antibody indices are elevated.},
