Nutritionists can teach individuals and caregivers how to plan and prepare small meals throughout the day that provide enough calories, fber, and fuid and how to avoid foods that are difcult to swallow. When individuals can no longer get enough nourishment from eating, doctors may advise inserting a feeding tube into the stomach. The use of a feeding tube also reduces the risk of choking and pneumonia that can result from inhaling liquids into the lungs. Breathing support As the muscles responsible for breathing start to weaken, people may experience shortness of breath during physical activity and difculty breathing at night or when lying down. Tere are several techniques to help people increase forceful coughing, including mechanical cough assist devices and breath stacking. In breath stacking, a person takes a series of small breaths without exhaling until the lungs are full, briefy holds the breath, and then expels the air with a cough. Doctors may place a breathing tube through the mouth or may surgically create a hole at the front of the neck and insert a tube leading to the windpipe (tracheostomy). People may choose to be fully informed about these considerations and the long-term efects of life without movement before they make decisions about ventilation support. Increasing evidence also suggests that various types of glial support cells and infammation cells of the nervous system may play an important role in the disease. Epigenetic changes can switch genes on and of, and thus can profoundly afect the human condition in both health and disease. Tese changes can occur in response to multiple factors, including external or environmental conditions and events. Biomarkers Biomarkers are biological measures that help to identify the presence or rate of progression of a disease or the efectiveness of a therapeutic intervention. Biomarkers can be molecules derived from a bodily fuid (such as those in the blood and cerebrospinal fuid), an image of the brain or spinal cord, or a measure of the ability of a nerve or muscle to process electrical signals. This work involves tests of drug-like compounds, gene therapy approaches, antibodies, and cell-based therapies. Clinical trials Many neurological disorders do not have efective treatment options. Clinical trials ofer hope for many people and an opportunity to help researchers fnd better ways to safely detect, treat, or prevent disease. S, that supply investigators with tissue from people with neurological and other disorders. The goal is to increase the availability of, and access to , high quality specimens for research to understand the neurological basis of the disease. Given the potential risks and inherent scarcity of human Departments of Pathology and Laboratory Services and Pediatrics, University of Ar immunoglobulin, careful consideration of its indications and kansas, Little Rock; gthe Department of Pediatrics, Allergy and Immunology, Mon administration is warranted.

A later retrospective study in 47 patients receiving immu of immunoglobulin in infants at risk for neonatal infection. Given the state of the the relationship between aging and the immune system has evidence, the current review panel recommends that recently attracted the attention of many researchers. In this light, nosenescence could lead to immunodeciency, some would argue assays of specic antibody avidity and actual function may prove 36 that immunosenescence does not equate to immune function useful.

Commonly used therapeutic modalities can mount a neutrophil response to bacterial infections. Treatment modalities low-dose (5 mg/kg every 3 weeks) therapy in a randomized, include corticosteroids, cyclophosphamide, cyclosporine, and double-blind, placebo-controlled trial in 20 patients with 210 more recently rituximab.

C Cuneiform Christmases Three wedge shaped bones on the medial & mid aspects of the foot. A memory mnemonic for the tarsal bones is Come to Columbus (the) Next (three) Christmases the talus articulates with the tibia and fibula in the ankle mortise and with the calcaneus and navicular distally. The talus is made up of a body that is wider anteriorly with three articular surfaces (the trochlea and posterior and middle calcaneal facets) and a posterior process (the posterior tabofibular ligaments). The neck of the talus connects with the head, which articulates with the navicular distally and the calcaneus inferiorly. Two-thirds of the talus is covered with cartilage served by the posterior tibial artery and other accessory vessels. The distal aspect of the calcaneus has an articular surface that receives the cuboid bone. The cuboid bone located on the lateral aspect of the foot and has a grooved plantar surface for articulation with the calcaneus, the lateral cuneiform, and the fourth and fifth metatarsals. The navicular is the most medial tarsal bone and lies between the talus and the cuneiforms. The cuneiforms are three bones (medial, intermediate, and lateral) that articulate with the navicular and posterior cuboid (lateral cuneiform) and the first three metatarsals. Injuries to the cuboid are often associated with other midfoot or Lisfranc fractures/dislocations. The bones of the foot are arranged in longitudinal and transverse arches, which provide a strong, shock absorbing support for the weight of the body. The two main arteries that supply the ankle and foot are the dorsalis pedis artery, a continuation of the anterior tibial artery of the leg, and the posterior tibial artery. Ankle Joint Three bones form the ankle joint: two long bones of the lower leg, the tibia and fibula, and one tarsal bone, the talus. The lateral malleolus is the expanded distal end of the fibula and the medial malleolus is the elongated process of the tibia. The inferior portions of the tibia and fibula form a deep socket or three-sided opening called a mortise into which the upper talus fits. The ankle is a synovial hinge type joint having flexion and extension movements only. Lateral stress on the joint can result in a sprained ankle with stretched or torn collateral ligaments. The tibia articulates with the distal femur by means of proximal medial facet (oval and concave) and lateral facet (circular and convex). The tibial shaft is triangular 24 and tapers to its thinnest point at the junction of the middle and distal thirds before widening again to form the tibial plafond. The proximal end of the tibia has two large processes called the medial and lateral condyles. The intercondylar eminence, often called the tibial spine, includes two small pointed prominences, the medial and lateral intercondylar tubercles. The tibial tuberosity is located on the proximal end of the tibia and has a rough textured prominence, which provides for attachments of the patellar tendon and the large muscle of the anterior thigh. The fibula is the smaller of the two leg bones and is located laterally and posteriorly to the larger tibia. The enlarged distal end of the fibula has a bump on the lateral aspect of the ankle joint and is called the lateral malleolus. The styloid process of the fibular head serves as the attachment for the fibular collateral ligament and the biceps tendon. The expanded distal fibular is referred to as the lateral malleolus and extends beyond the distal margin of the medial malleolus. Together with the inferior distal surface of the tibia, these structures comprise the ankle mortise. Knee Joint the knee is a compound joint consisting of two condyloid joints and one sellar joint. The knee is a synovial type joint, which is enclosed in a capsule that has posteromedial and posterolateral recesses extending 15 millimeters (mm) distal to the subchondral surface of the tibial plateau. The medial and lateral femoral condyles articulate with the corresponding tibia facets. Intervening menisci serve to deepen the concavity of the facets, help protect the articular surface, and assist in rotation of the knee. The medial and lateral menisci are fibrocartilage discs between the articular facets of the tibia and the femoral condyles and serve as shock absorbers for direct impact to the knee joint. The medial meniscus tears three times more often than the more mobile lateral meniscus. The patella is the largest sesamoid bone in the human body and serves three functions. It is a fulcrum for the quadriceps, protects the knee joint, and enhances lubrication of the knee. The cruciate ligaments are crucial to anteroposterior stability and the collateral ligaments provide varus/valgus stability. The posterior compartments are supplied by the tibial nerve and contain preaxial muscles. The anterior and lateral compartments are supplied by the common peroneal nerve and contain postaxial muscles. The gastrocnemius muscles, semi-membranousus, and biceps border the popliteal fossa. Femur the femur is the longest and strongest bone in the entire body and its anatomic boundaries includes the knee and hip joint. The distal femur has two large rounded condyles that are joined anteriorly but separated distally and posteriorly by a deep intercondylar fossa or notch. The inferior surface of the ilium contains the acetabular notch and is deepened by the fibrocartilaginous labrum. The primary muscles of the hip joint are the iliopsoas, rectur femoris, and sartorius. Establishing a positive relationship with the patient from the moment they enter the facility until they depart is very important. This requires that the staff projects a cheerful, positive reception and that the patient be informed as they progress through the imaging examination. Patient advocacy involves treating patients as individuals, protecting their dignity 2 and privacy, and respecting their choices. Radiographers perform advocacy duties when they ensure that proper radiation protection is used during every imaging examination and that established quality control procedures are used consistently. Consistent implementation of effective quality control measures improves image quality and allows the clinician to accurately diagnose and deliver appropriate treatment in a timely manner. As a representative of the medical facility, a radiographer has less than 30 3 seconds to make a good impression when the patient arrives. It is important for radiographers to understand that the patient is a consumer of services and that they are customers. The five most important needs of patients, as customers of health care 3 services, are reliability, responsiveness, assurance, empathy, and tangibles. For health care institutions to remain in business they must be viewed as reliable or else patients will go elsewhere for care. Patients also want services delivered by providers who give care and services in an empathetic manner. Tangible expectations include such things as an attractive and hygienic environment and fully functioning and well-maintained equipment. During any given day, radiographers provide care to a number of patients, each with specific and unique imaging examination needs. To complete the imaging examination, the radiographer may need to provide assistance to the patient in meeting general as well as personal needs. Radiographers can show concern by such simple things as being friendly and courteous. The following are suggestions that radiographers may be able to use when relating to patients. Showing concern the radiographer should provide a welcome environment and should not hurry the patient or appear rushed to get to the next patient. Caring is demonstrated when the radiographer listens to , provides information for, helps, communicates with, shows 4 respect towards, touches, and protects the patient. Showing respect the radiographer can show respect to others by creating a welcoming we care environment in the imaging area. All sexes, races, religions, and socioeconomic levels are represented in any patient population. Respect can be verbalized in the way one talks to patients; such interactions may be communicated by the choice of words and the body language used by the radiographer. Adopting the motto treat others as you would want to be treated is helpful in showing respect. The radiographer should react and respond in a professional manner to what is observed and heard while providing care. To reach this goal, radiographers must communicate effectively to patients and staff. Radiographers, co-workers, and patients represent a diverse population from a variety of cultures, religions, races, and ethnic characteristics. Cultural differences can become barriers when they are not acknowledged and adaptations made to respect them. Recognizing other accepted cultural differences such as body language, facial gestures, and attire are also important for incorporating cultural diversity equality into everyday action. In certain societies it is considered disrespectful to look directly into the eyes of the other person during a conversation. Also in some cultures, repeated head nods may indicate respect rather than agreement with what is being said. In some societies, women must keep their bodies completely covered with clothing, allowing only the eyes to be seen. The radiographer needs to be aware that in some cultures touching of any kind is an intimate act and the patients may find any touching offensive. To avoid unintentionally offending a patient during positioning, the radiographer should tell the patient in advance what they are about to do. Everyone harbors reactions, habits, and traditions common to their ethnic and socioeconomic background. Radiographers are no exception and these personal feelings are sometimes difficult to ignore; however, radiographers must not let personal 5,6 feelings affect the care they deliver. Every society has written and unwritten codes of 30 conduct that govern everyday life. For effective communication and cooperation to occur between the radiographer and others, these differences should not become barriers. Radiographers should be aware of these differences, acknowledge them, and respect others when providing imaging services. Language differences pose a substantial risk for miscommunication between the radiographer and the patient. Large hospitals and clinics may employ an interpreter or arrange for one as needed. English speaking family members, friends, or an advocate may accompany some non-English speaking patients.
