Intimate partner violence, which describes physical or sexual assault, or both, of a spouse or sexual intimate, is a common health-care issue. In this article, I have reviewed research on the mental and physical health sequelae of such violence. ⋯ Intimate partner violence has been noted in 3-13% of pregnancies in many studies from around the world, and is associated with detrimental outcomes to mothers and infants. I recommend increased assessment and interventions for intimate partner violence in health-care settings.

Norepinephrine-resistant hypotension when associated with septic shock has a high rate of mortality, which might possibly be reduced by infusion of low-dose vasopressin. However, rebound hypotension often arises after treatment is stopped, and the drug usually has to be administered for several days. ⋯ We were able to discharge four patients from intensive care subsequently. Terlipressin seems to be an effective rescue therapy, which is able to restore blood pressure in patients with catecholamine-resistant septic shock, without obvious complication.

Randomized Controlled Trial Clinical Trial
Efficacy of three short-course regimens of zidovudine and lamivudine in preventing early and late transmission of HIV-1 from mother to child in Tanzania, South Africa, and Uganda (Petra study): a randomised, double-blind, placebo-controlled trial.
Large reductions in transmission of HIV-1 from mother to child have been achieved in more-developed countries due to the use of antiretrovirals. Short-course regimens, suitable for resource-poor countries, have also been shown to significantly reduce peripartum HIV-1 transmission. We assessed the efficacy of short-course regimens with zidovudine and lamivudine in a predominantly breastfeeding population. ⋯ Although at week 6 after birth, regimens A and B were effective in reducing HIV-1 transmission, benefits have diminished considerably after 18 months of follow-up. Introduction of short-course regimens to prevent mother-to-child transmission of HIV-1 in less-developed countries should be accompanied by interventions to minimise the risk of subsequent transmission via breastfeeding.

Several genes, including the major susceptibility gene RET, have roles in development of Hirschsprung's disease. Results of genetic-linkage analysis of patients with familial disease with both long-segment and short-segment phenotypes have shown close linkage with the RET locus. We aimed to investigate whether both RET mutations and polymorphisms contribute to phenotype of Hirschsprung's disease. ⋯ These observations lend support to the idea that both RET alleles have a role in pathogenesis of Hirschsprung's disease, in a dose-dependent fashion. We also showed that the c135G/A polymorphism modifies the phenotype by a within-gene interaction between the c135A variant and a mutation.
