Filter by:Background: When a person is exposed to something that causes an infection, the body sends a type of cell called CD8 T cells to attack it. Those cells are also found in breast milk. Nursing mothers pass these cells to their child, which helps the child fight infections, too. Researchers want to learn more about how CD8 cells work to keep people healthy. Objective: To learn more about how the human body fights off infections. Eligibility: People age 18 years and older who either have an infection, are suspected to have an infection, or recently got a vaccine. The household contacts of these people and people who have not been recently exposed to any infection are also needed. Design: Participants will be screened with a medical and health history and physical exam. They may have blood tests. The first study visit can be the same day as screening. It can be up to 3 months later. For those visits, screening tests will be repeated. At the first visit, participants will have blood collected from an arm vein. Participants who are breastfeeding may provide a small sample of breast milk. They may collect it at home or bring a pumping device to NIH to collect it. NIH can also provide a breast pump. Participants may be contacted for up to 1 year after the first visit to give samples of blood and/or breast milk. Up to 4 additional visits, which will each take about 1 hour, may be scheduled. A personal physician or local lab can collect blood from participants and ship it to NIH. Breast milk cannot be shipped.
Foot drop deformity is a life limiting condition characterized by loss of ankle dorsiflexion and eversion. Main condition leading to drop foot condition include irrecoverable muscle and nerve injuries, poliomyelitis, drug poisoning, strokes, cerebral palsy, Charcot - Marie - Tooth disease, meningomyelocele, club foot, Friedreich's ataxia and Leprosy (1-4). Anterior transposition of Posterior tibialis tendon (PTT) is the gold standard for surgical restoration of functional dorsiflexion of a permanently paralyzed foot (1, 4-10). Two methods of rerouting the posterior tibialis tendon have been reported, one through the interosseous membrane i.e. Interosseous route (7, 10) and second subcutaneously around the medial side of tibia i.e. Extramembranous or circumtibial route (11-13). Both these techniques have been widely described in literature (4-16) and are being extensively used in surgical management of foot drop. The selection of technique depends on surgeon choice and patient factors. There is a clinical equipoise with regards to these two techniques of Tibialis posterior tendon transfer and through our study we aim to compare the clinical and functional outcomes of these two techniques. There are no studies in literature which compare the clinical and functional outcomes with regards to both these methods. Although there are many studies to demonstrate the functional and clinical effectiveness of the respective procedures, there is a paucity of clinical trials comparing these two surgical techniques with regards to clinical and functional outcomes. Furthermore there are no head to head clinical trials to compare the outcomes with regards to these two methods of Tibialis Posterior tendon transfer (Medline search dated 03/03/ 2012) we propose to compare the clinical and functional outcomes with regards to the two techniques i.e extra membranous and Interosseous technique of Tibialis Posterior tendon transfer performed in patients with foot drop as a result of nerve palsy. Through our prospective randomized trial we aim to answer the research question, whether one method has any superior outcome over the other?
