Lymphedema Explained
Lymphedema Explained samer kareem 1,139 Views • 2 years ago

The lymphatic system is a network of specialized vessels (lymph vessels) throughout the body whose purpose is to collect excess lymph fluid with proteins, lipids, and waste products from the tissues. This fluid is then carried to the lymph nodes, which filter waste products and contain infection-fighting cells called lymphocytes. The excess fluid in the lymph vessels is eventually returned to the bloodstream. When the lymph vessels are blocked or unable to carry lymph fluid away from the tissues, localized swelling (lymphedema) is the result.

Pyogenic Granuloma Surgery
Pyogenic Granuloma Surgery samer kareem 4,021 Views • 2 years ago

Pyogenic granuloma (lobular capillary hemangioma[1] ) is a relatively common benign vascular lesion of the skin and mucosa whose exact cause is unknown. Also see the Medscape Reference article Oral Pyogenic Granuloma. Pyogenic granulomas are misnamed; they are neither infectious nor granulomatous. The lesion usually occurs in children and young adults as a solitary, glistening red papule or nodule that is prone to bleeding and ulceration. Pyogenic granulomas typically evolve rapidly over a period of a few weeks, most often on the head, neck, extremities, and upper trunk. Pyogenic granuloma often arises in pregnancy (or rarely with oral contraceptive usage), particularly on the gingiva or elsewhere in the oral mucosa, and then is termed the "pregnancy tumor." Other pyogenic granuloma variants that have been well documented include the disseminated, subcutaneous, intravenous, and medication-induced (for example, retinoid, antiretroviral, and oncologic agent) subtypes. Removal of pyogenic granuloma is indicated to alleviate any bleeding, discomfort, cosmetic distress, and diagnostic uncertainty. A number of malignant tumors may clinically mimic pyogenic granuloma, making histopathologic confirmation important if the presentation is atypical. Aside from cutaneous and oral lesions, pyogenic granuloma has been reported throughout the gastrointestinal tract and upper airway, at various ocular locations, the central nervous system, the bladder, and the internal vasculature. This article discusses only cutaneous and oral involvement.

Meningitis
Meningitis samer kareem 2,672 Views • 2 years ago

Bacterial meningitis is very serious and can be deadly. Death can occur in as little as a few hours. While most people with meningitis recover, permanent disabilities such as brain damage, hearing loss, and learning disabilities can result from the infection. There are several types of bacteria that can cause meningitis. Some of the leading causes of bacterial meningitis in the United States include Streptococcus pneumoniae, group B Streptococcus, Neisseria meningitidis, Haemophilus influenzae, and Listeria monocytogenes.

Meniscus Tear repair
Meniscus Tear repair samer kareem 5,942 Views • 2 years ago

A torn meniscus is one of the most common knee injuries. Any activity that causes you to forcefully twist or rotate your knee, especially when putting your full weight on it, can lead to a torn meniscus. Each of your knees has two menisci — C-shaped pieces of cartilage that act like a cushion between your shinbone and your thighbone. A torn meniscus causes pain, swelling and stiffness. You also might feel a block to knee motion and have trouble extending your knee fully. Conservative treatment — such as rest, ice and medication — is sometimes enough to relieve the pain of a torn meniscus and give the injury time to heal on its own. In other cases, however, a torn meniscus requires surgical repair.

Coronary artery bypass grafting (CABG) is a type of surgery that improves blood flow to the heart. Surgeons use CABG to treat people who have severe coronary heart disease (CHD). CHD is a disease in which a waxy substance called plaque (plak) builds up inside the coronary arteries.

Severe Cystic Acne
Severe Cystic Acne Scott 27,383 Views • 2 years ago

Cystic acne is a severe type of acne in which the pores in the skin become blocked, leading to infection and inflammation. The skin condition mainly affects the face, but also often affects the upper trunk and upper arms. Acne most often affects adolescents and young adults, with an estimated 80 percent of people between 11 and 30 years of age experiencing acne at some point. Cystic acne is the most severe form and affects far fewer people. In 2009, the Centers for Disease Control and Prevention (CDC) found that acne was the top reason people gave for visiting a dermatologist.

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.

This operation can be performed as an open or laparoscopic (keyhole procedure). During the operation the sigmoid colon is removed. This involves taking away the blood vessels and lymph nodes to that part of the bowel. The surgeon then re-makes the join (anastomosis) between the remaining left side of the colon and the top of the rectum. The surgeon may use either sutures or special staples to make this join.

Microvilli
Microvilli samer kareem 2,048 Views • 2 years ago

Cells may have slender extensions of the cell membrane to form cilia or the smaller extensions called microvilli. The microscopic microvilli effectively increase the surface area of the cell and are useful for absorption and secretion functions. A dramatic example is the human small intestine. The tissue has small fingerlike extensions called villi which are collections of cells, and those cells have many microvilli to even further increase the available surface area for the digestion process. According to Audesirk & Audesirk, this can give an effective surface area of about 250 square meters for absorption.

Lower Extremity Occlusive Disease
Lower Extremity Occlusive Disease samer kareem 1,276 Views • 2 years ago

Claudication, which is defined as reproducible ischemic muscle pain, is one of the most common manifestations of peripheral arterial occlusive disease (PAOD) caused by atherosclerosis. Claudication occurs during physical activity and is relieved after a short rest. Pain develops because of inadequate blood flow. Examination of a patient with claudication should include a complete lower-extremity evaluation and pulse examination, including measuring segmental pressures. Attempt to palpate pulses from the abdominal aorta to the foot, with auscultation for bruits in the abdominal and pelvic regions. When palpable pulses are not present, a handheld Doppler device may be used to assess circulation.
