Frontotemporal degeneration (FTD) is a disease process that results in progressive damage to the temporal and/or frontal lobes of the brain. It causes a group of brain disorders that share many clinical features.

Digoxin is used to treat heart failure, usually along with other medications. It is also used to treat a certain type of irregular heartbeat (chronic atrial fibrillation). Treating heart failure may help maintain your ability to walk and exercise and may improve the strength of your heart. Treating an irregular heartbeat can decrease the risk for blood clots, an effect that may reduce your risk for a heart attack or stroke.

Elbow Joint Arthrocentesis samer kareem 1,156 Views • 2 years ago

Arthrocentesis involves both the puncture of a joint and the aspiration of its synovial fluid. It is typically used to make an accurate diagnosis of a painful, warm, swollen joint. Removal of excess fluid can be therapeutic. Analysis of the removed fluid helps to decipher its etiology. [1]

The procedure was performed under wrist block regional anesthesia with tourniquet control. A single Chinese finger trap was used on the thumb with 5 to 8 lb of ongitudinal traction. The arm was held down with wide tape around the tourniquet securing it to the hand table to serve as countertraction. A shoulder holder, rather than a traction tower, was used to facilitate fluoroscopic intervention more easily. The Trapeziometacarpal joint was detected by palpation. Joint distension was achieved by injecting 1 to 3 mL of normal saline (Fig. 1). It is important to distally direct the needle approximately 20 degrees to clear the dorsal flare of the metacarpal base and enter the joint capsule. This course should be reproduced upon entering with arthroscopic sleeve/ trocar assembly to minimize iatrogenic cartilage injury. Fluid distention is important to facilitate this. The incision for the 1-R (radial) portal, used for proper assessment of the dorsoradial ligament, posterior oblique ligament, and ulnar collateral ligament, was placed just volar to the abductor pollicis longus tendon. The incision for the 1-U (ulnar) portal, for better evaluation of the anterior oblique ligament and ulnar collateral ligament, was made just ulnar to the extensor pollicis brevis tendon. A short-barrel, 1.9-mm, 30- degree inclination arthroscope was used for complete visualization of the CMC joint surfaces, capsule, and ligaments, and then appropriate management was done, as dictated by the stage of the arthritis detected (Fig. 2A). A full-radius mechanical shaver with suction was used in all the cases, particularly for initial debridement and visualization. Most of the cases were augmented with radiofrequency ablation to perform a thorough synovectomy and radiofrequency was also used to perform chondroplasty in the cases with focal articular cartilage wear or fibrillation. Chondroplasty refers to thedebridement of the fibrillated cartilage to improve vascularity of the cartilage and enhance the growth of fibrocartilage. Ligamentous laxity and capsular attenu- ation were treated with thermal capsulorraphy using a radiofrequency shrinkage probe. We were careful to avoid thermal necrosis; hence, a striping technique was used to tighten the capsule of the lax joints. The striping technique refers to thermal shrinkage performed in longitudinal stripes on the lax capsule, so as to leave vascular zones between the stripes; hence, thermal necrosis is prevented. Arthroscopic stage I disease was characterized by synovitis without any cartilage wear, wherein a synovectomy coupled with thermal capsulor- raphy as described was performed.

arteriosclerosis
arteriosclerosis samer kareem 1,015 Views • 2 years ago

Atherosclerosis is a narrowing of the arteries caused by a buildup of plaque. It’s also called arteriosclerosis or hardening of the arteries. Arteries are the blood vessels that carry oxygen and nutrients from your heart to the rest of your body. As you get older, fat and cholesterol can collect in your arteries and form plaque. The buildup of plaque makes it difficult for blood to flow through your arteries. This buildup may occur in any artery in your body and can result in a shortage of blood and oxygen in various tissues of your body. Pieces of plaque can also break off, causing a blood clot. Atherosclerosis can lead to heart attack, stroke, or heart failure if left untreated.

Superior Capsular Reconstruction
Superior Capsular Reconstruction samer kareem 1,347 Views • 2 years ago

Superior capsule reconstruction (SCR) is a promising alternative treatment for irreparable posterosuperior rotator cuff tears (Figure 1). It utilizes a graft from the superior glenoid to the greater tuberosity to stabilize the humeral head. In a study by Mihata and colleagues of 23 patients who underwent SCR with a fascia lata autograft at a minimum of 2 years follow-up, the American Shoulder and Elbow Surgeons (ASES) score improved significantly from 23.5 preoperatively to 92.9. Postoperative MRI showed 83% of patients had intact reconstructions with no progression of muscle atrophy.

Lipoma Removal Procedure
Lipoma Removal Procedure samer kareem 3,301 Views • 2 years ago

Lipomas are single or multiple, benign subcutaneous tumors that are easily recognized because they are soft, rounded, or lobulated and movable against the overlying skin. Many lipomas are small but may also enlarge to 6 cm. They occur especially on the neck, trunk, and on the extremities but can occur anywhere on the body. Lipomas are composed of fat cells that have the same morphology as normal fat cells, and there is a connective tissue framework. Angiolipomas have a vascular component and may be tender in cold ambient temperature. These often require excision, whereas other lipomas should be excised only when considered disfiguring. Liposuction can also be performed when liposomas are soft and thus have only a minor connective tissue component.

http://vencer-la-diabetes-rapido.info-pro.co/ Como Controlar La Diabetes Tipo 2 Naturalmente Sin Medicamentos, Pre Diabetes Y Diabetes Tipo 1. https://youtu.be/BOSkQ5MnjT0 Que es la Insulina? Una definición practica sin adentrarnos en terminos estrictamente medicos es que la insulina es una hormona formada por 51 aminoácidos. Dentro del páncreas, las células beta producen la hormona llamada insulina. Con cada comida, las células beta liberan insulina para ayudar al cuerpo a utilizar o almacenar en la sangre la glucosa que se obtiene de los alimentos. Su déficit provoca la diabetes mellitus y su exceso provoca hiperinsulinismo con hipoglucemia. En las personas con diabetes tipo 1, el páncreas no produce insulina. Las células beta han sido destruidas y se necesitan inyecciones de insulina para utilizar la glucosa de las comidas. Las personas con diabetes tipo 2 producen insulina, pero sus cuerpos no responden bien a la misma. Algunas personas con diabetes tipo 2 necesitan medicamentos para la diabetes o inyecciones de insulina para ayudar a su cuerpo a utilizar la glucosa para obtener energía. * La insulina no se puede tomar como una píldora, ya que se descompone durante la digestión al igual que la proteína en los alimentos. Se debe inyectar en la grasa debajo de la piel para que llegue a la sangre. Existen diferentes tipos de insulina en función de la rapidez con que trabajan, y en funcion de su duración. La insulina viene en diferentes concentraciones, la más común es U-100. Tipos de insulina: * De Acción Rápida: Comienza a trabajar unos 15 minutos después de la inyección, con picos en aproximadamente 1 hora, y continúa trabajando por un tiempo de 2 a 4 horas. Tipos: Insulina glulisina (Apidra), la insulina lispro (Humalog) y la insulina aspart (NovoLog). * Regular o de Acción Corta: Generalmente llega al torrente sanguíneo a los 30 minutos después de la inyección, picos de entre 2 a 3 horas después de la inyección, y es efectiva durante aproximadamente 3 a 6 horas. Tipos: Humulin R, Novolin R * De Acción Intermedia: Generalmente llega al torrente sanguíneo de aproximadamente 2 a 4 horas después de la inyección, picos de 4 a 12 horas y eseficaz durante aproximadamente 12 a 18 horas. Tipos: NPH (Humulin N, Novolin N) * De Acción Prolongada: Alcanza el torrente sanguíneo varias horas después de la inyección y tiende a disminuir los niveles de glucosa de manera bastante uniforme durante un período de 24 horas. Tipos: La insulina detemir (Levemir) y la insulina glargina (Lantus) Nota: Esta información debes consultarla siempre con tu medico especialista. La insulina Tiene 3 Características: El inicio: Es el tiempo antes de que la insulina alcance el torrente sanguíneo y se inicie la reducción de la glucosa en sangre. Pico: Es el tiempo durante el cual la insulina está surtiendo el máximo efecto en términos de reducción de la glucosa en sangre. La duración: Es cuánto tiempo la insulina continúa reduciendo la glucosa sanguínea.
