The brain is the most complex organ in our body. It controls everything we do, from simple things such as breathing, to complex things such as co-ordinating our movements. The brain stores our memories, allows us to think and speak, and controls how we behave

Your body has nerves that connect your brain to the rest of your organs and muscles, just like telephone wires connect homes all around the world. When you want your hand to move, your brain sends signals through your nerves to your hand telling the muscles to contract. But your nerves don’t just say “hand, move.” Instead your nerves send lots of electrical impulses (called action potentials) to different muscles in your hand, allowing you to move your hand with extreme precision.

Heart failure, sometimes known as congestive heart failure, occurs when your heart muscle doesn't pump blood as well as it should. Certain conditions, such as narrowed arteries in your heart (coronary artery disease) or high blood pressure, gradually leave your heart too weak or stiff to fill and pump efficiently.

Perleche, queilosis, estomatitis, boqueras, son otras denominaciones con las que se conoce a la queilitis angular. Las comisuras de los labios presentan lesiones inflamatorias. Las grietas verticales a nivel de la piel pueden profundizarse y provocar ulceraciones, llagas, sangrados, infecciones, descamaciones, costras. Con ello, sobrevendrán las dificultades para hablar, para sonreír, para ingerir los alimentos y las bebidas. La queilitis angular no discrimina. Puede afectar tanto a los bebés como a los niños, a los adultos o a los ancianos. A menudo las causas derivan de una mala alimentación, carente de los nutrientes esenciales para el organismo. También las deficiencias nutricionales pueden deberse a la incapacidad orgánica para absorber los nutrientes, como sucede con la enfermedad celíaca. O las causas pueden provenir de estímulos que afectan una piel hipersensible, como ciertas alergias. O se puede producir por ciertos medicamentos. O incluso por prótesis dentarias mal ajustadas. Y la queilitis puede agravarse en una persona que padece micosis como la Cándida albicans. Lo cierto es que la boca es una zona húmeda, condición que dificulta la cura e incluso aumenta las manifestaciones nocivas en la piel y en la membrana que tapiza la cavidad interior de la boca. La humedad constante podrá ser caldo de cultivo para hongos y bacterias. Como muchas afecciones, la queilitis angular suele tener su origen en una mala alimentación. La hipovitaminosis o escasa provisión de vitamina A está considerada como posible desencadenante de la afección. Asimismo, es atribuible a la falta de minerales como el zinc, el hierro y la riboflavina (vitamina B2). Una vez que la queilitis angular está en proceso, la falta de nutrientes se agudiza.

Medulloblastoma is a fast-growing, high-grade tumor. It is the most common of the embryonal tumors—tumors that arise from “emybryonal” or “immature” cells at the earliest stage of their development. The most common symptoms of medulloblastoma include behavioral changes, changes in appetite, symptoms of increased pressure on the brain (eg, headache, nausea, vomiting, and drowsiness, as well as problems with coordination). Unusual eye movements may also occur. Like many tumor types, the exact cause of medulloblastoma is not known. However, scientists are making significant strides in understanding its biology. Changes have been identified in genes and chromosomes (the cell’s DNA blueprints) that may play a role in the development of this tumor. There are also a few rare, genetic health syndromes that are associated with increased risk for developing this tumor.

A diagnosis of sarcoidosis is established on the basis of compatible clinical and radiologic findings and histologic evidence of the presence of noncaseous epithelioid cell granulomas in one or more organs and the absence of causative organisms or particulates (16). Granulomas of known causes and local sarcoidlike reactions must be excluded. Granulomatous lesions may result from many conditions, including tuberculosis, berylliosis, leprosy, hypersensitivity pneumonitis, Crohn disease, primary biliary cirrhosis, and fungal disease. Moreover, local sarcoidlike reactions may be seen in lymph nodes that drain a neoplasm or a site of chronic inflammation (19). Such reactions also have been seen in patients who have undergone chemotherapy and radiation therapy (23). If biopsy of lymph nodes or pulmonary or pleural tissue is necessary for diagnosis, one of three techniques may be used: transbronchial biopsy, CT-guided biopsy, or surgical biopsy (24). The use of a surgical technique may be warranted when the results of biopsy with another procedure are not definitive and biopsy of mediastinal lymph nodes, lung, or both is required. This can generally be done with minimally invasive procedures, such as cervical mediastinoscopy, the Chamberlain procedure (a parasternal minithoracotomy for biopsy of the aortopulmonary window or para-aortic nodes), or video-assisted thoracoscopic surgical biopsy (25).

If you’re considering an epidural to help manage the pain of childbirth, you’re not alone. More than 60 percent of women delivering at hospitals elect for an epidural during labor. And with good reason: An epidural is considered one of the safest methods of pain control, with just one in 3,000 pregnancies experiencing serious complications. It’s also good for you, since you’ll remain awake and alert during the birth, as well as for your baby, since the drugs will barely reach your bloodstream (so they can’t get into hers).

Pulmonary edema is usually caused by a heart condition. Other causes include pneumonia, exposure to certain toxins and drugs, and being at high elevations. Depending on the cause, pulmonary edema symptoms may appear suddenly or develop over time. Mild to extreme breathing difficulty can occur. Cough, chest pain, and fatigue are other symptoms. Treatment generally includes supplemental oxygen and medications.
