...Special Class Discussion OI or Osteogenesis Imperfecta, which is commonly referred to as Brittle Bone disease. It causes Isaiah to be susceptible to fractures and breaks in his bone very easily. Isaiah was diagnosed with type III OI during the second trimester (20 weeks), which is a very severe form, but survivable. Though the diagnosis was not the best, the couple, Vicky and Dave, have made the most out of the situation. From what I have had the opportunity to observe via the blog, Isaiah is living a full life given the circumstances. Full of Disney whimsy and seasonal outings just as any kid would experience. I love the fact that his parents are both very understanding and even tempered people, from what they present in the blog. Making the childs life as stress free as possible. Though they try not to focus on the hardships in their blog, some of it is very apparent when you read between the lines. One instance is when Vicky wrote about how she could not tell if Isaiahs moaning and crying was due to hunger, a fever or a fracture. The condition carries a huge burden, regardless of how hard the parents try and normalize his life. The parents try and maintain a positive atmosphere, but in my mind I am very curious as to what toll it is taking on their physical and emotional health? Questions: 1) Do you have any plans for Isaiah as he gets older? Education? 2) How is Isaiah in social situations with other children? 3) Does Isaiah have any favorite activities...

...happens when the ligaments are stretched beyond their normal range of motion (sprained). CAUSES This injury is caused by a blow to the tip of your finger that pushes your finger toward your hand. RISK FACTORS This injury is more likely to develop if you play sports. SYMPTOMS Symptoms of this injury include: Pain. Swelling. Discoloration and bruising around the joint. Difficulty bending or straightening the finger. Not being able to use the finger normally. DIAGNOSIS Your health care provider may suspect a jammed finger based on your symptoms, especially if you had a recent finger or hand injury. Your health care provider will examine your finger. You may also have an X-ray to check for a broken bone (fracture). TREATMENT In most cases, a jammed finger may be treated by: Wearing a splint. Taping the injured finger to the fingers beside it (buddy taping). Medicine used to treat pain. Depending on the type of injury, you may also have to do exercises after your finger has begun to heal. This helps you regain strength and mobility in the finger. HOME CARE INSTRUCTIONS Take medicines only as directed by your health care provider. Apply ice to the injured area: Put ice in a plastic bag. Place a towel between your skin and the bag. Leave the ice on for 20 minutes, 2–3 times per day. Raise the injured area above the level of your heart while you are sitting or lying down. Wear the splint or tape...

...LIQUID METAL EMBRITTLEMENT (LME) RAGHAV MOHAN Graduate Student M.S in Technical Entrepreneurship and Management University of Rochester INTRODUCTION Liquid metal embrittlement (LME) is a phenomenon of practical importance, where certain ductile metals experience drastic loss in tensile ductility or undergo brittle fracture when tested in the presence of specific liquid metals. Generally, a tensile stress or a residual stress is needed to induce embrittlement. Many mechanisms were proposed to explain the phenomenological characteristics of LME. The significance of liquid metal embrittlement is revealed by the practical observation of several structures experiencing ductility losses and cracking during hot dip galvanizing or during subsequent fabrication. Liquid metal embrittlement effects can be observed even in solid state, when one of the metals is brought close to its melting point (e.g. cadmium-coated parts operating at high temperature). This phenomenon is known as solid metal embrittlement. OBSERVATIONS OF LME Mechanical structures are typically a space frame fabricated from parallel large diameter tubes, called chords, cross braced by smaller diameter perpendicular and diagonal tubes(e.g. sign bridge structures over freeway) .After welding, the structure is hot dip galvanized. The hot dip galvanizing process consists of submerging the structure in a bath of molten zinc. This leaves a relatively uniform zinc coating over the entire structure upon...

...a broken bone may occur. Depending on the severity of the break, fracture surgery may be needed to help in the healing process. Different Types of Fractures Each type of fracture is different and unique. An expert orthopedic doctor will be able to determine if fracture surgery will be needed. Each individual patient will have specific needs in helping the bones to heal properly. • Stable or straight fracture barely causes the bone to be out of alignment. • An open, compound fracture is creates a wound in the area. Depending on the impact, the bone may or may not...

...A regular smoker will require 30 weeks to heal a natural fracture, which is 6 weeks longer than a non – smoker. For example, the Shinbone fracture is a major fracture and a regular smoker will take around 32 weeks for that while a non- smoker can heal it in 25 weeks. So this illustrates that there is a significant difference in the healing time. The first step toward bone healing the mesenchymal cells transforming into cartilage forming Cells (osteoblasts). They build a scaffolding over the fracture, through which the osteocytes flow and gradually harden, thus forming a new bone. This entire process takes about three months. A healing fracture is considered soft until the bone is completely formed. But for smokers, the bone may remain...

...up a fake injury and used fake recources to demonstrate APA. Abstract Explosive tendonitis is an injury that occurs when a bone is fractured and heals over a tendon, pinching the tendon causing an explosive pain every time the tendon is used. This research was aimed at identifying the prevention and treatment of the injury. Two periodical articles, one book, one encyclopedia, and one internet site were used to research this topic. The injury is rare, but may occur in any athlete where a stress fracture can occur near a tendon. Introduction Stress fractures can occur in most athletics and several different bones. This injury can be caused by a blow to the bone by a significant force, but mostly occurs to a bone that is repeatidly struck or overused. According to Stevensonburg (2006) "Sixty-eight percent of all stress fracture occur in runners and sprinters and sports that require a high volume of either activity" (p. 37). Stevensonburg (2006) also stated "Stress fractures can be prevented by a steady and easy increase in the stated activities so that bones can grow to meet the high demand that the athlete is trying to reach. In order for the injury to heal, activity on that particular bone must be limited to little or none. Explosive tendonitis occurs when the tendon is pressed into the bone where the tendon may become cought in the crack enough so that it becomes pinched into the bone. Method Several pieces of literature were researched to describe this injury...

...Case #1: Brigham and Women’s/Faulkner Hospitals This case takes an in depth look into the evolving medical industry. Key aspects of this case focus on the benefits and drawbacks of a merger between large and community sized hospitals and the possible cost subsidizing that may occur and the impact the qualitative factors may play in such cases. Overview of Industry: Health Care costs began to rise while insurance reimbursements began to fall. This led to a larger amount of patients being treated on outpatient basis. This aided in temporarily curbing the costs associated with overnight patients. AMCs therefore focused on primary care as means of reducing operating costs. Thus a lot of emphasis was placed on cost control. Managed Care plans lead to capped fee for hospitals. As a result, BWH saw a drop in incoming patients. AMCs thus focused on primary care as means of reducing operating costs. Community doctors were reluctant to recommend AMC doctors, instead sent patients to less costly hospitals. The solution seemed to be pointing towards possible mergers. The mergers’ purpose was to achieve Economies of Scale and also get access to the patients and knowledge of community hospitals and fill the gap where the large hospitals lacked market penetration. OUTLINE OF BWH HOSPITAL: Largest hospital in New England. Often ranked as best in service. High end teaching hospital. Employs more than 12,000 people with 44,000 patients. Annual research budget of $400...

...HBR CASE STUDY Crescordia’s products are respected the world over. Now, rivals have launched a radical–albeit still buggy–new technology. Can the company afford to sit out the revolution? Holding Fast by John T. Gourville “N DANIEL VASCONCELLOS ow remember, with every blow of the hammer, you’ve got to feel the femoral nail advancing through the bone. If you don’t, then for heaven’s sake, stop. It might be impinging on the cortex or it might be too large for the canal. Keep whacking, and you’ll fracture the cortex.” The trainer’s calm, authoritative voice boomed out across the room as a dozen orthopedic surgeons toiled away on the cadaver limbs laid out before them. Pausing to observe the technique of one of the surgeons, he glanced up to see his boss, CEO Peter Walsh, crack open the door and squeeze through, trying his best to be unobtrusive. The trainer glanced at the clock.“Okay, let’s save some of this fun for the afternoon,” he called out. “We’ll meet in the lobby in ten minutes and walk over to lunch.” In addition to making a range of products from artificial hips to scalpels, Crescordia was one of a handful of major companies that developed, manufactured, and sold the steel and titanium plates, nails, and screws – known as fix- ation devices – that surgeons used to repair broken bones. At least twice a month, Crescordia hosted training sessions like this one for orthopedic surgeons who used the company’s products. Walsh joined the group for lunch as often...

...BACKGROUND The Burton Group of Hospitals in downtown Minneapolis has a patient satisfaction score of 55% compared to 80% in comparable hospitals in the area. Based on patient feedback, the three major complaints in rank order are long waiting, too much movement, and lack of patient focus. The daily census data indicates that 22% of the patients that came to the Emergency Department (ED) had simple fractures. The Hospital is located next to several recreational park systems, therefore the Emergency Department treats a significant amount of patients from recreational sports. Simple fracture procedure has the lowest satisfaction (40%) among the hospital patients. RECOMMENDATION We advise The Burton Group of Hospitals to reduce the waiting times of simple fracture patients by optimizing processes and following efficient practices, by reducing unnecessary patient and staff movement across the Emergency Department and by improving customer service through a patient-oriented culture. The proposed efficiency model can reduce the waiting time for simple fracture patients requiring procedure to just 123 minutes from 317 minutes. Our detailed recommendations for management are as follows: * Reduce the long waiting times by optimizing processes and following efficient practices. Long waiting times are patients’ biggest concern. Patients have to wait long since many processes in ED are inefficient due to duplication, disorganization and lack of technology. Eliminating...

...Nurses Impact Lives Beyond: Case Studyd Nurses Impact Lives Beyond: Case Study Nurses Impact Lives Beyond Pre-hospital Phase: It was cold and dark, when the helicopter was dispatched to a scene flight for motor vehicle crash with double entrapment one May morning at 0230. Two of the three patients, are unresponsive and in critical and unstable condition. This is the first encounter our patient would have with a registered nurse providing and directing his care. The nurse possesses both acute care and pre-hospital expertise and would work collaboratively with police, fireman, good Samaritans, EMT’s and paramedics to access the patient, provide timely triage, life -saving interventions and rapid transport to the closest trauma center. Each team member has a pre-defined and respected role; the nurse is the senior health care provider and assumes the leadership role with a calm, confident demeanor that is reassuring to the team. This patient was a 25 year old man, unrestrained driver of a vehicle that hit a brick wall head-on at a high rate of speed. Of his two passengers, one of them is a brother, all require 20 minutes of extrication time from the severely damaged vehicle. After freeing our patient, the team works together to assess and stabilize him. His initial vital signs are worrisome, with a BP of 140/80, pulse of 160 and spontaneous respiratory rate of 8. The nurse assumes his care and quickly supports his respiratory rate by bagging and suctioning...

...In case of exogeneous bone implants, the major disadvantage is that they may be rejected by human body, disease may be transmitted together with the implant, and also the clinical performance of exogenous bone is considerably inferior to fresh endogenous graft material. For these reasons there is growing need for fabrication of artificial hard tissue replacement implants. Research into novel materials for biomedical applications is ever increasing as the medical community look to improve the way in which disorders and trauma are treated. Issues with current materials and the additional trauma associated with the use of bone grafts has pushed research towards new materials to aid the required repair and/or the regeneration of bone after fracture or the removal of bony defects or cancerous bone. Many new materials have been developed in an attempt to address these concerns but there are still some issues surrounding the appropriateness of their mechanical properties, the ability of degradable materials to retain their properties once implanted and the ability to form the material in situ to the requirements of the surgeon. A biomaterial is a synthetic material used to replace part of a living system or to function in intimate contact with living tissue. There are a number of definitions describing biomaterials, but the most widely accepted definition is as follows: “a biomaterial is a nonviable material used in a medical device, intended to interact with biological...

...“Stump the Teacher”: Non-Ossifying Fibromas Shamaya Moore Kaiser Permanente School of ALlied Health Science March 14, 2013 The patient arrived to radiology on August 5, 2012. The patient was a 10 year old hispanic male whom presented to the hospital with pain in his right ankle. Prior to coming into the radiology department he had fallen on a play structure at his school. Immediately after his fall he was brought to the hospital by his parents. As a result the patient was x-rayed on August 5, 2012. An ankle complete series was performed which consisted of an AP, Oblique, and Lateral view. However, due to his age comparison films were also taken of his left ankle which consisted of only an ap and lateral. According to the radiology report from the images obtained the patient was said to have a non-ossifying fibroma in his right distal tibia metaphysis region. The recommendation following his visit from the radiologists was for the patient to be seen again for a followup in six months. On March 1, 2013 the patient returned to the department for his 6 month followup. Since the patient was being seen for a followup on this visit instead of for trauma like his initial visit, only three images were obtained. An AP, Oblique, and Lateral view of only his right ankle. According to the radiology reports from this visit the patient still was said to have a non ossifying fibroma on his right lower leg/ankle. A non-ossifying fibroma is a benign, non-aggressive...

...Broken arm A bone fracture (sometimes abbreviated FRX or Fx, Fx, or #) is a medical condition in which there is a break in the continuity of the bone. A bone fracture can be the result of high force impact or stress, or trivial injury as a result of certain medical conditions that weaken the bones, such as osteoporosis, bone cancer, or osteogenesis imperfecta, where the fracture is then properly termed a pathological fracture. Although broken bone and bone break are common colloquialisms for a bone fracture, break is not a formal orthopedic term. Treatment: The most important aspect of first aid is to stabilize the arm. Do this by using a towel as a sling. Place it under the arm and then around the neck. An alternate approach to keep the arm from moving is to position a rolled and taped newspaper along the swollen area and to tape it in place. Apply ice to the injured area. This can help to decrease pain and swelling. Place ice in a bag and leave it on the arm for 20-30 minutes at a time. It may be helpful to place a towel around the ice bag or in between the bag and the skin to protect the skin from getting too cold. Never put ice directly on the skin. Symptoms: Most broken arms have these symptoms: A large amount of pain and increased pain when moving the arm Swelling Maybe an obvious deformity compared to the other arm Possible open wound either from the bone puncturing the skin or from the skin being cut during the injury Decreased sensation...
