Meta-Analysis Review
In 1984, Newell and coworkers were the first to suggest that testicular cancer might have a viral etiology since it showed similar characteristics to Hodgkin's lymphoma. A systematic literature review and meta-analysis was conducted to investigate a possible association between viral infections (EBV, CMV, Parvovirus B19, HPV, and HIV) and testicular cancer. Articles published from 1985 through June 2010 were located from MEDLINE and EMBASE databases, 21 articles were finally included in the review. For infection with EBV, CMV, Parvovirus B19, and HIV the pooled OR were 4.80 (95% CI 0.98-23.54), 1.85 (95% CI 0.92-3.70), 2.86 (95% CI 0.35-23.17), and 1.79 (95% CI 1.45-2.21) respectively. No pooling was possible for HPV infection studies due to small numbers. The results support a possible association, but more epidemiological studies with better viral identification and localization methods are needed to verify these findings.

Review
Acute isolated velopharyngeal insufficiency (VPI) is a clinical entity mainly reported in children. We undertook a systematic review in order to better characterize its features. Following a Medline search (1960-2012), the authors reviewed and analyzed the cases of acute VPI in children; 36 cases were found. The most common presenting features were hypernasal speech (97 %), nasal reflux (73 %), and dysphagia (49 %). 73 % of the children were males and 27 % females, of 8.9 ± 2.5 years. In all the cases the VPI was unilateral. One quarter of the children had a recent episode of febrile illness and 11 % of the children had an identified infection at the time of presentation (HAV, parvovirus B19, measles, and Coxsackie virus). No associated cause was found in the other cases. All cases resolved completely (67 %) or partially (33 %) without any treatment (89 %) or with prednisolone (11 %). Acute VPI represents a separate entity within the spectrum of VPI and it is a benign self-limiting disorder. The cause remains undetermined but an infectious disorder may play a role at least in some cases. Follow-up is mandatory in order to eliminate progressive conditions such as brainstem neoplasms or inflammatory diseases.
