In this retrospective study, we analysed 25 guide-wire-assisted Vollmar endarterectomies of an occluded superficial femoral artery. In 96% of the cases, the patient suffered from a Fontaine stage III or IV. After a mean follow-up of 24.7 months, limb salvage is 96%. The patency rate is 84% which is comparable with a femoropopliteal bypass with a reversed greater saphenous vein graft. We advocate the Vollmar endarterectomy as a valuable alternative surgical treatment for occlusive superficial femoral artery in the absence of a greater saphenous vein or in young smoking patients (< 65 years).

Since its publication in 1993, the World Bank's World Development Report, Investing in Health, has been subjected to much criticism, particularly over the way it proposes to measure the health losses summarized in the concept of the 'burden of disease', and to establish priorities for health interventions according to the reduction in mortality and disability they could produce and what they would cost. Some of these criticisms are justified, and are recognized by the WDR; others arise from misunderstanding or misapplication of the concepts. Sifting these criticisms to arrive at a better understanding requires looking at what kind of analysis is involved, how the subjective elements of the exercise were determined, and how they can be used to choose which interventions deserve priority when a country cannot meet all its citizens' health needs.
BACKGROUND: Increased maternal and fetal risks have been reported in pregnancies following unexplained infertility. Our aims were to examine the obstetric and perinatal outcome of singleton pregnancies in couples with unexplained infertility and explore the impact of fertility treatment. METHODS: Women with unexplained infertility were identified from the Aberdeen Fertility Clinic Database. Their unit numbers were matched against the Aberdeen Maternity and Neonatal Databank (AMND) in order to extract obstetric records of those women with subsequent pregnancy outcomes. The general obstetric population served as a control group. RESULTS: Women with unexplained infertility were older [30.8 versus 27.9 years, 95% confidence interval (CI) for difference = +2.4 to +3.4] and more likely to be primiparous (59 versus 40%, 95% CI = +1.3 to +1.9). After adjusting for age and parity they had a higher incidence of pre-eclampsia, abruptio placentae, preterm labour, emergency Caesarean section and induction of labour in comparison with the general population (P < 0.05). Perinatal outcome did not differ between women with unexplained infertility and those of the general population. The multiple pregnancy rate was 5.4% higher following fertility treatment than in women who conceived spontaneously (95% CI = +2.8 to +9.7). CONCLUSIONS: Women with unexplained infertility are at higher risk of obstetric complications which persist even after adjusting for age, parity and fertility treatment. The reasons are however unclear and merit further study.
