With an Ophthalmoscope, light is shone into the eye and the retina and the optic nerve is examined. This is called as Examination of the Fundus. This is what the eye-doctor sees when he peeps into your eye! Through the transparent cornea, into the dark interior. The Fundus Exam When he looks into the eye with the Ophthalmoscope, he sees a orange glowing interior. That is the retina. The retina is actually transparent. It appears bright because of blood vessels in the choroid layer below. It is like looking at your ear against the bright sunlight. The yellow circle is the Optic Nerve, the cable of vision! A red, shiny dot attracts attention. That is the macula. If indicated, the exam of periphery of the retina is done with an Indirect ophthalmoscope. The ophthalmologist wears this instrument on the head and focuses the light into the eye with a lens held in his hand. This is usually done in a dark room.
What Causes Ulcers? No single cause has been found for ulcers. However, it is now clear that an ulcer is the end result of an imbalance between digestive fluids in the stomach and duodenum. Most ulcers are caused by an infection with a type of bacteria called Helicobacter pylori (H. pylori). Factors that can increase your risk for ulcers include: Use of painkillers called nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin, naproxen (Aleve, Anaprox, Naprosyn, and others), ibuprofen (Motrin, Advil, some types of Midol, and others), and many others available by prescription; even safety-coated aspirin and aspirin in powered form can frequently cause ulcers. Excess acid production from gastrinomas, tumors of the acid producing cells of the stomach that increases acid output (seen in Zollinger-Ellison syndrome) Excessive drinking of alcohol Smoking or chewing tobacco Serious illness Radiation treatment to the area What Are the Symptoms of an Ulcer? An ulcer may or may not have symptoms. When symptoms occur, they may include: A gnawing or burning pain in the middle or upper stomach between meals or at night Bloating Heartburn Nausea or vomiting In severe cases, symptoms can include: Dark or black stool (due to bleeding) Vomiting blood (that can look like "coffee-grounds") Weight loss Severe pain in the mid to upper abdomen
A stye (also called a hordeolum) is a small, red, painful lump that grows from the base of your eyelash or under the eyelid. Most styes are caused by a bacterial infection. There are two kinds of styes: External hordeolum: A stye that begins at the base of your eyelash. Most are caused by an infection in the hair follicle. It might look like a pimple. Internal hordeolum: A stye inside your eyelid. Most are caused by an infection in an oil-producing gland in your eyelid.
The hepatic portal system is the system of veins comprising the hepatic portal vein and its tributaries. It is responsible for directing blood from the region of the gastrointestinal tract between the esophagus and rectum and also includes venous drainage from the supplementary organs such as the spleen and pancreas.
Intestino Irritable Tratamiento, Colon Irritable, Tratamiento Para El Colon Irritable--- http://intestino-irritable-tratamiento.plus101.com --- Si usted está sufriendo de Síndrome del Intestino Irritable SII, aquí hay una serie de técnicas y estrategias que se conocen para aliviar grandemente los síntomas a largo y corto plazo. La alimentación es la fuente de energía primordial que tenemos y es por eso que hay que darle una importancia suprema a la hora de querer atacar los síntomas del SII. Se recomienda el consumo de hierbas, tales como: manzanilla, consuelda, aceite de onagra, bálsamo de limón, hinojo, canela, nuez moscada, cúrcuma, todas las especias y enzimas digestivas. Todas ellas producen grandes beneficios para su organismo, dentro de los cuales destacamos: La manzanilla actúa como carminativo, así como calmante y agente tonificante para el tracto digestivo. Los aceites esenciales de manzanilla también han contribuido a aliviar cólicos intestinales e irritación en los animales. La manzanilla se toma normalmente tres veces al día, entre las comidas, en una forma de té. La consuelda tiene un uso como agente tópico para mejorar la cicatrización de heridas, úlceras en la piel, tromboflebitis y torceduras. También se utiliza para las personas con problemas gastrointestinales, como úlceras de estómago y el síndrome del intestino irritable, y para quienes sufren problemas pulmonares. Una combinación de menta, comino y otras dos hierbas carminativas (para aliviar los gases), semillas de hinojo y ajenjo, han resultado ser un tratamiento eficaz para los dolores abdominales. La acacia tiene un alto contenido de fibra y con frecuencia se recomienda para aliviar la irritabilidad intestinal. Las frutas como la papaya, el plátano, el mango, la piña, las fresas y los arándanos son altamente recomendables. Las verduras como las patatas dulces, la calabaza y las zanahorias no pueden dejar de ser parte de su dieta. Tenga cuidado con algunos de los medicamentos recetados para el SII ya que algunos de ellos han sido retirados del mercado debido a que contenían ingredientes tóxicos. Algunos ingredientes contenidos en medicamentos de venta libre para el resfriado también han demostrado efectos negativos en pacientes con SCI. Recomendamos las gotas de zinc como una alternativa durante un resfriado ya que no irrita el estómago y tiene visibles resultados de estímulo inmunológico. Los alimentos que se deben evitar: lácteos, huevos (especialmente la yema debido al alto contenido de grasa), brócoli, maíz, aceites hidrogenados, jarabe de maíz alto en fructosa, manzanas (debido al alto contenido de fructosa), frijoles, chocolate (debido a la cafeína) , café, té con cafeína.

Schistosomiasis is a parasitic disease caused by flukes (trematodes) of the genus Schistosoma. After malaria and intestinal helminthiasis, schistosomiasis is the third most devastating tropical disease in the world, being a major source of morbidity and mortality for developing countries in Africa, South America, the Caribbean, the Middle East, and Asia. (See Epidemiology and Prognosis.) [1] More than 207 million people, 85% of who live in Africa, are infected with schistosomiasis, [1] and an estimated 700 million people are at risk of infection in 76 countries where the disease is considered endemic, as their agricultural work, domestic chores, and recreational activities expose them to infested water. [1, 2] Globally, 200,000 deaths are attributed to schistosomiasis annually. [3] Transmission is interrupted in some countries. [2] (See Etiology and Epidemiology.)
Barrett's esophagus is a complication of chronic (long lasting) and usually severe gastrointestinal reflux disease (GERD), but occurs in only a small percentage of patients with GERD. Criteria are needed for screening patients with GERD for Barrett's esophagus. Until validated criteria are available, it seems reasonable to do screening endoscopies in GERD patients who cannot be taken off acid suppression therapy after two to three years. The diagnosis of Barrett's esophagus rests upon seeing (at endoscopy) a pink esophageal lining that extends a short distance (usually less than 2.5 inches) up the esophagus from the gastroesophageal junction and finding intestinal type cells (goblet cells) on biopsy of the lining. There is a small but definite increased risk of cancer of the esophagus (adenocarcinoma) in patients with Barrett's esophagus.
