Eight patients, 3 men and 5 women, aged between 24 and 40 years who had herpes zoster ophthalmicus (HZO) were seen in the Eye Department of the University of Nigeria Teaching Hospital, Enugu between 1994 and 1997. One of the patients was already on treatment for active pulmonary tuberculosis at the time he was first seen. All had skin eruptions at different stages of development in the area of distribution of the first trigeminal nerve on the affected side of the face and head. ⋯ During this period skin eruptions and anterior segment signs improved in 5 patients while remaining stable in 3 others; post-herpetic neuralgia persisted on the affected side in 4 patients. Patients who were HIV seropositive did not recover as quickly or to the same extent as the seronegative ones. It is concluded that HZO infection may indicate underlying HIV infection in young Africans as has been found in whites.

Hepatocellular carcinoma (HCC) is one of the most common cancers in the world and is particularly prevalent in China. China is also a hyperendemic area for hepatitis B virus (HBV) infection. Although a strong association between HBV infection and HCC has been established previously, the role of hepatitis C virus (HCV) infection and the interaction between HBV and HCV in the development of HCC has not been adequately explored. The major objective of this study is to determine the relationship between HBV or HCV infection and HCC by use of case-control study in Henan, China. ⋯ This is the first reported case-control study of HCC in Henan, China. This study provides further evidence that chronic HBV infection is strongly associated with the development of HCC among this population. Our results have demonstrated that HCV and HBV infection are independent and probably additive risk factors for HCC.

Meta AnalysisThe effect of pregnancy on survival in women infected with HIV: a systematic review of the literature and meta-analysis.
To investigate the effect of pregnancy on disease progression and survival in women infected with HIV by a systematic review of the literature and meta-analysis. ⋯ The findings of this review have implications for women infected with HIV who are pregnant or are considering a pregnancy. There does appear to be an association between adverse maternal outcomes and pregnancy in women infected with HIV, although this association is not strong. The relation may be due to the result of bias including residual confounding. Further large scale observational studies with long term follow up are required before this issue can be fully resolved.

ReviewThe association between maternal HIV infection and perinatal outcome: a systematic review of the literature and meta-analysis.
To investigate the association between maternal HIV infection and perinatal outcome by a systematic review of the literature and meta-analysis. ⋯ The findings of this review have implications for women infected with HIV who are planning a pregnancy or who find themselves pregnant. There appears to be an association, although not strong, between maternal HIV infection and an adverse perinatal outcome. This relationship may be due to bias including uncontrolled or residual confounding. There does, however, appear to be a real and large increase in the risk of infant death in developing countries associated with maternal HIV infection, especially so when there has been an attempt to control for confounding.

The objective of this study is to estimate the risk of subarachnoid hemorrhage produced by oral contraceptive use. ⋯ This meta-analysis of observational studies suggests that oral contraceptive use produces a small increase in the risk of subarachnoid hemorrhage.
