Limited Open Achilles Tendon Repair in Supine Position With Modified Ring Forceps: A Technique Tip.

We present a modification to prior Achilles tendon repair techniques that utilizes readily available noncommercial instrumentation, mini-open incisions, and supine positioning, thus maximizing surgical efficiencies and reducing complications. In our experience, this is a safe and effective technique that minimizes anesthetic requirements and operating room time. Level V, expert opinion.

Women in limbo: life course consequences of infertility in a Nigerian community.

Infertility is a devastating problem around the world, particularly in the high fertility context of sub-Saharan Africa. Regardless of its medical origins, infertility causes African women personal grief and economic deprivation.This research was conducted among the Ijo who are organized into exogamous patrilineal descent groups.

Definitions and the experience of fertility problems: infertile and sub-fertile women, childless mothers, and honorary mothers in two southern Nigerian communities.

Although infertility causes women considerable grief, social stigma, and economic deprivation, scholars have paid little attention to infertility's definitions that may depart from the standard Western usage and how such definitions influence the way women experience the condition. This article, by listening to individual women's experiences of infertility in two Nigerian communities, examines these definitions and differentiates between culturally salient categories of infertility. In distinguishing between different kinds of childless women and those with low fertility, we intend to enhance understandings of infertility by considering women's subjective understandings of the condition and thus moving beyond the current medical definition.

Limits on anomalous trilinear gauge couplings in Zγ events from pp¯ collisions at √s=1.96 TeV.

Using Zγ candidate events collected by the CDF detector at the Tevatron Collider, we search for potential anomalous (non-standard-model) couplings between the Z boson and the photon. Zγ couplings vanish at tree level and are heavily suppressed at higher orders; hence any evidence of couplings indicates new physics. Measurements are performed using data corresponding to an integrated luminosity of 4.
