Meta Analysis
Human papillomavirus type-distribution in condylomata acuminata of mainland China: a meta-analysis.
The aim of this work was to study the human papillomavirus (HPV) type-distribution in condylomata acuminata (CA) of mainland China and to estimate the potential role of HPV prophylactic vaccines for CA in mainland China. Forty-three studies using polymerase chain reaction to detect HPV were included in this meta-analysis, and totally 5247 CA cases and 436 controls were included. The overall and type-specific prevalence of HPV 6, 11, 40, 42, 43, 44 were estimated using non-conditional logistic regression model. ⋯ Estimated HPV types 6, 11, 40, 42 positive fractions in CA were 54.9%, 41.1%, 2.7% and 2.0%, respectively, and exactly 0% for HPV types 43 and 44. HPV 6 and/or 11-positive fractions were 83.0% in mainland China. Thus, prophylactic HPV vaccine has the potential to protect up to 83% of CA cases in mainland China.

Meta Analysis
Azithromycin vs. benzathine penicillin G for early syphilis: a meta-analysis of randomized clinical trials.
The World Health Organization estimates that at least 12 million people are infected with syphilis in the world. Southeast Asia accounts for 5.8 million; Africa accounts for 3.5 million. There has been controversy in using the two kinds of antibiotics for early syphilis. ⋯ Cure rate (OR=1.37), 95% CI (1.05, 1.77) and the risk difference for cure rate between the two drugs were statistically significant. Although the gastrointestinal adverse effect of azithromycin is five times more than the adverse effect of penicillin G benzathine, the differences are not significant. Azithromycin achieved a higher cure rate than penicillin G benzathine in a long follow-up.
