With keratoconus, the clear, dome-shaped tissue that covers the eye (cornea) thins and bulges outward into a cone shape. Its cause is unknown. Symptoms first appear during puberty or the late teens and include blurred vision and sensitivity to light and glare. Vision can be corrected with glasses or contact lenses early on. Advanced cases may require a cornea transplant.
A thyroid biopsy is a procedure in which a small sample of tissue is removed from the thyroid gland and looked at under a microscope for cancer, infection, or other thyroid problems. The thyroid gland is found in front of the windpipe (trachea), just below the voice box (larynx). A sample of thyroid tissue can be taken by: Fine-needle biopsy. Your doctor puts a thin needle through the skin and into the thyroid gland. Many thyroid specialists like to use a needle biopsy method rather than surgery. Open biopsy. Your doctor makes a cut (incision) through the skin to see the thyroid gland. This method is done when other tests have not found the cause of your symptoms. Core needle biopsy. Your doctor inserts a needle with a special tip and removes a sample of tissue about the size of a grain of rice.
What is peripheral neuropathy? Your peripheral nervous system connects the nerves from your brain and spinal cord, or central nervous system, to the rest of your body. This includes your: arms hands feet legs internal organs mouth face The job of these nerves is to deliver signals about physical sensations back to your brain.
Peptic ulcers are open sores that develop on the inside lining of your stomach and the upper portion of your small intestine. The most common symptom of a peptic ulcer is stomach pain. Peptic ulcers include: Gastric ulcers that occur on the inside of the stomach Duodenal ulcers that occur on the inside of the upper portion of your small intestine (duodenum) The most common causes of peptic ulcers are infection with the bacterium Helicobacter pylori (H. pylori) and long-term use of aspirin and certain other painkillers, such as ibuprofen (Advil, Motrin, others) and naproxen sodium (Aleve, Anaprox, others). Stress and spicy foods do not cause peptic ulcers. However, they can make your symptoms worse.
COPD stands for chronic obstructive pulmonary (lung) disease. COPD is a term applied to a family of diseases that includes emphysema, chronic bronchitis, and emphysema due to alpha-1 antitrypsin deficiency. COPD usually progresses gradually, causing limited airflow in and out of the lungs. COPD adds to the work of the heart. Diseased lungs might reduce the amount of oxygen that goes to the blood. High blood pressure in blood vessels from the heart to the lungs makes it difficult for the heart to pump. Lung disease can also cause the body to produce too many red blood cells, which might make the blood thicker and harder to pump.
Obstructive lung diseases include conditions that make it hard to exhale all the air in the lungs. People with restrictive lung disease have difficulty fully expanding their lungs with air. Obstructive and restrictive lung disease share the same main symptom: shortness of breath with exertion.
Rhinoplasty, sometimes referred to as a "nose job" or "nose reshaping" by patients, enhances facial harmony and the proportions of your nose. It can also correct impaired breathing caused by structural defects in the nose. What surgical rhinoplasty can treat Nose size in relation to facial balance Nose width at the bridge or in the size and position of the nostrils Nose profile with visible humps or depressions on the bridge Nasal tip that is enlarged or bulbous, drooping, upturned or hooked Nostrils that are large, wide or upturned Nasal asymmetry If you desire a more symmetrical nose, keep in mind that everyone's face is asymmetric to some degree. Results may not be completely symmetric, although the goal is to create facial balance and correct proportion. Rhinoplasty to correct a deviated septum Nose surgery that's done to improve an obstructed airway requires careful evaluation of the nasal structure as it relates to airflow and breathing. Correction of a deviated septum, one of the most common causes of breathing impairment, is achieved by adjusting the nasal structure to produce better alignment.
