Replantation after amputation of 5 fingers
Replantation after amputation of 5 fingers samer kareem 18,277 Views • 2 years ago

Since the first replant more than 50 years ago, thousands of severed body parts have been reattached, preserving the quality of life for thousands of patients through improved function and appearance that the void remaining after amputation cannot provide. Ronald Malt performed the first replantation on May 23, 1962 at Massachusetts General Hospital on a 12-year-old boy who had his right arm amputated in a train accident. [1, 2] This amputation occurred at the level of the humeral neck.

Bowel Obstruction
Bowel Obstruction samer kareem 1,837 Views • 2 years ago

A bowel obstruction happens when either your small or large intestine is partly or completely blocked. The blockage prevents food, fluids, and gas from moving through the intestines in the normal way. The blockage may cause severe pain that comes and goes. This topic covers a blockage caused by tumors, scar tissue, or twisting or narrowing of the intestines. It does not cover ileus, which most commonly happens after surgery on the belly (abdominal surgery). What causes a bowel obstruction? Tumors, scar tissue (adhesions), or twisting or narrowing of the intestines can cause a bowel obstruction. These are called mechanical obstructions . In the small intestine, scar tissue is most often the cause. Other causes include hernias and Crohn's disease, which can twist or narrow the intestine, and tumors, which can block the intestine. A blockage also can happen if one part of the intestine folds like a telescope into another part, which is called intussusception.

Anaphylactic shock
Anaphylactic shock samer kareem 1,562 Views • 2 years ago

Anaphylaxis is a severe, potentially life-threatening allergic reaction. It can occur within seconds or minutes of exposure to something you're allergic to, such as a peanut or the venom from a bee sting. The flood of chemicals released by your immune system during anaphylaxis can cause you to go into shock; your blood pressure drops suddenly and your airways narrow, blocking normal breathing. Signs and symptoms of anaphylaxis include a rapid, weak pulse, a skin rash, and nausea and vomiting. Common triggers of anaphylaxis include certain foods, some medications, insect venom and latex. Anaphylaxis requires an immediate trip to the emergency department and an injection of epinephrine. If anaphylaxis isn't treated right away, it can lead to unconsciousness or even death.

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.

Amiodarone uses samer kareem 1,505 Views • 2 years ago

This medication is used to treat certain types of serious (possibly fatal) irregular heartbeat (such as persistent ventricular fibrillation/tachycardia). It is used to restore normal heart rhythm and maintain a regular, steady heartbeat. Amiodarone is known as an anti-arrhythmic drug. It works by blocking certain electrical signals in the heart that can cause an irregular heartbeat.

ALPHA & BETA BLOCKERS
ALPHA & BETA BLOCKERS samer kareem 4,013 Views • 2 years ago

Alpha blockers relax certain muscles and help small blood vessels remain open. They work by keeping the hormone norepinephrine (noradrenaline) from tightening the muscles in the walls of smaller arteries and veins, which causes the vessels to remain open and relaxed. This improves blood flow and lowers blood pressure.

Ectopia cordis!
Ectopia cordis! samer kareem 8,179 Views • 2 years ago

Ectopia cordis is a rare genetic defect. During a baby’s development in utero, their chest wall doesn’t form correctly. It also doesn’t fuse together as it normally would. This prevents the heart from developing where it should, leaving it defenseless and exposed outside of the protection of the chest wall. The defect affects about one in 126,000 births. In partial ectopia cordis, the heart is located outside the chest wall, but just under the skin. The heart can be seen beating through the skin.

Aortic Valve Tumor
Aortic Valve Tumor samer kareem 1,905 Views • 2 years ago

Papillary fibroelastoma is the third most common primary tumor of the heart and is most likely to involve the cardiac valves. Like myxomas, they arise from the endocardium in most patients and since these tumors are often incidental findings at echocardiography or autopsy, the true incidence is difficult to estimate. Most patients are older than 60 years, which also contrasts with myxomas. Papillary fibroelastomas can embolize, leading to severe neurological complications and therefore, surgical removal is advised, although there is controversy regarding small incidental lesions and the need for surgery.

Gestational trophoblastic disease
Gestational trophoblastic disease samer kareem 2,291 Views • 2 years ago

What is gestational trophoblastic disease? Cancer starts when cells in the body begin to grow out of control. Cells in nearly any part of the body can become cancer, and can spread to other areas of the body. To learn more about how cancers start and spread, see What Is Cancer? Gestational trophoblastic (jeh-STAY-shuh-nul troh-fuh-BLAS-tik) disease (GTD) is a group of rare tumors that involve abnormal growth of cells inside a woman's uterus. GTD does not develop from cells of the uterus like cervical cancer or endometrial (uterine lining) cancer do. Instead, these tumors start in the cells that would normally develop into the placenta during pregnancy. (The term gestational refers to pregnancy.) GTD begins in the layer of cells called the trophoblast (troh-fuh-BLAST) that normally surrounds an embryo. (Tropho- means nutrition, and -blast means bud or early developmental cell.) Early in normal development, the cells of the trophoblast form tiny, finger-like projections known as villi. The villi grow into the lining of the uterus. In time, the trophoblast layer develops into the placenta, the organ that protects and nourishes the growing fetus.
