Recombinant Human Growth Hormone Treatment in Adults with Prader-Willi Syndrome

May 23, 2018 Medical Technology Directory

Health Problem: Prader-Willi syndrome (PWS) is a genetic disorder that is highly variable and can affect multiple body systems; there is an associated pattern of physical findings with significant cognitive, neurologic, endocrine, and behavioral abnormalities. Studies in the United States have reported a prevalence rate ranging from 1 per 16,062 to 1 per 25,000 population. Management of PWS focuses on its complications and is age dependent. Growth hormone (GH) therapy has become standard care to normalize height and improve mobility, activity levels, and body composition (increase lean body mass, decrease fat mass). Technology Description: In adults with PWS, an evaluation of...

Comparative Effectiveness Review of Bariatric Surgeries for Treatment of Obesity in Adolescents

May 17, 2018 Medical Technology Directory

Health Problem: Child and adolescent obesity is a body mass index (BMI) at or above the sex-specific 95th percentile on BMI-for-age growth charts. Consequences of obesity in children and adolescents include type 2 diabetes mellitus, obstructive sleep apnea, hypertension, nonalcoholic fatty liver disease, hyperlipidemia, musculoskeletal disorders, endocrine conditions, psychological and psychosocial issues, and high risk of progression to adult obesity. Technology Description: Bariatric surgery refers to the surgical treatment of severe obesity through procedures that reduce the size of the stomach to restrict caloric intake and/or change the intestinal anatomy to induce malabsorption. The surgical procedures most commonly used in adolescents...

Continuous Passive Motion Devices for Shoulder Indications

May 9, 2018 Medical Technology Directory

Health Problem: Joint contractures refer to a decreased range of motion (ROM) in diarthrodial (or movable) joints. Contractures may occur with joint disease, trauma, or healing, or secondarily to structural changes in muscle, tendons, ligaments, and/or skin that limit elasticity. Immobilization of a joint may create conditions that contribute to the development of contractures. During immobilization, collagen weakens and becomes less organized, which can lead to the formation of joint adhesions. For shoulders, surgical repair of the rotator cuff presents a risk of contracture during postoperative healing. Technology Description: Continuous passive motion (CPM) allows for passive motion therapy to be provided...

Mechanical Stretching Devices for the Treatment of Joint Contractures of the Extremities

May 9, 2018 Medical Technology Directory

Health Problem: Joint contractures refer to a decreased range of motion (ROM) that impairs function. Contractures may occur with many different afflictions, including neurological conditions, joint trauma, or healing; contractures may also occur secondarily to structural changes in muscle, tendons, ligaments, and/or skin that limit elasticity. Immobilization of a joint may create conditions that contribute to the development of contractures. Technology Description: Mechanical stretching devices are intended to restore ROM by stretching joints. Devices provide passive stretching to an adjustable degree for a selected duration for multiple sessions. Devices can provide stretching for longer periods than a physical therapist is able...

Comparative Effectiveness Review of Laparoscopic Surgery for Gastroesophageal Reflux Disease Refractory to Medical Therapy

April 26, 2018 Medical Technology Directory

Health Problem: Gastroesophageal reflux disease (GERD) is one of the most common gastrointestinal disorders in the United States and Europe. The prevalence of GERD is estimated at 8.8% to 25.9% in Europe and 18.1% to 27.8% in North America. GERD is defined by the presence of chronic symptoms or mucosal damage caused by an abnormal reflux of gastric contents into the esophagus. Technology Description: Laparoscopic fundoplication is a minimal access surgical procedure for patients with long-standing GERD. A range of laparoscopic procedures are now used for the treatment of GERD; these include total (Nissen) fundoplication and various types of partial fundoplication....
