Currently, the German cervical cancer screening program encompasses an annual cytological Papanicolaou (Pap) smear. However, primary screening for cervical cancer using human papillomavirus (HPV) DNA testing detects cervical pre-cancerous lesions with a significantly higher sensitivity than the Pap smear-based cytology. ⋯ The presented risk-adapted Wolfsburg Cervical Cancer Prevention Project ("Wolfsburg Model") has been shown to be effective and feasible in identifying women at risk and for avoiding unnecessary procedures for those who are double negative, thus allowing longer screening intervals and cost savings. Acceptance rates for the program were high for both participating women and gynecologists.

In Germany, cervical cancer screening is regulated by the German Federal Ministry of Health and Social Security and is available for all women from the age of 20 on the basis of the Papanicolaou (PAP) smear. The purpose of this study was to determine the positive predictive value of HR-HPV testing for precancerous lesions of the cervix uteri. Therefore, this study especially focused on the diagnostic accuracy of testing for one or more of the HPV types 16, 18 and 45 for all HR-HPV positive women, since HR-HPV infections with subtypes 16, 18 and 45 have demonstrated a higher risk of developing cervical cancer [Bulk S, et al. Br J Cancer 2006; 94:171-5]. ⋯ These preliminary results demonstrate that starting cervical cancer screening at the age of 20 years remains important as seventeen (25%) of the 68 histologically verified CIN 3 lesions arose in women who were younger than 30 years. Furthermore, our data suggest that adding an HR-HPV test that detects one or more of the HR-HPV types 16, 18 and 45 in conjunction with cytology could help to identify women with an underlying cervical lesion who have an elevated risk of developing severe cervical lesions. This might offer the opportunity of a decrease in incidence and mortality rates that are related with invasive cervical cancer.

Human rhinovirus type C is a recently discovered species that has been associated with respiratory tract infections of unusual severity in some cases. However, the precise type of diseases associated with this new human rhinovirus needs to be investigated. ⋯ This supported the existence of a disseminated viral infection that extended to the pericardial space. 5'UTR and VP1 sequence analysis performed directly from the BAL sample allowed genotyping of the virus as a human rhinovirus C. This observation highlights the need for adapted diagnostic tools and the potential for the new rhinovirus species C to cause complications, including pericarditis.

Human rhinoviruses (HRVs) are often concurrently detected with other viruses found in the respiratory tract because of the high total number of HRV infections occurring throughout the year. This feature has previously relegated HRVs to being considered passengers in acute respiratory infections. HRVs remain poorly characterized and are seldom included as a target in diagnostic panels despite their pathogenic potential, infection-associated healthcare expenditure and relatively unmoderated elicitation of an antiviral state. ⋯ HRVs were proportionately under-represented among viral co-detections. For some period, HRVs may render the host less likely to be infected by other viruses.

Case Reports
Papular-purpuric gloves and socks syndrome associated with B19V infection in a 6-year-old child.
A 6 year-old girl was admitted for evaluation of a fever associated with a petechial rash of 2 days' duration. She was in good general condition with no acute distress. Inspection of the skin revealed an amazing papular and purpuric rash of predominantly acral and symmetrical distribution and sharply demarcated on the ankles. ⋯ Most of the time, the disease is self-limited with a short course and a benign prognosis. A very similar disease has been described in some children. The distinctive clinical characteristics of PPGSS in children should be recognized by paediatrician in particular at the emergency room in order to avoid superfluous explorations.
