With so many antibiotics available, it isn't possible to list all of them here. But common antibiotics that are generally considered safe during pregnancy include penicillins (such as amoxicillin and ampicillin), cephalosporins (such as cephalexin), and erythromycin.
COPD (chronic obstructive pulmonary disease) makes it hard for you to breathe. The two main types are chronic bronchitis and emphysema. The main cause of COPD is long-term exposure to substances that irritate and damage the lungs. This is usually cigarette smoke. Air pollution, chemical fumes, or dust can also cause it. At first, COPD may cause no symptoms or only mild symptoms. As the disease gets worse, symptoms usually become more severe. They include A cough that produces a lot of mucus Shortness of breath, especially with physical activity Wheezing Chest tightness Doctors use lung function tests, imaging tests, and blood tests to diagnose COPD. There is no cure. Treatments may relieve symptoms. They include medicines, oxygen therapy, surgery, or a lung transplant. Quitting smoking is the most important step you can take to treat COPD.
Multiple sclerosis (MS) affects the brain and spinal cord. Early MS symptoms include weakness, tingling, numbness, and blurred vision. Other signs are muscle stiffness, thinking problems, and urinary problems. Treatment can relieve MS symptoms and delay disease progression.
In PRK the epithelium (top layer of the cornea) is scraped off and then the laser treatment is applied. A contact lens is used as a "bandage" to decrease discomfort. The epithelium then grows back over the bare area during the next few days.
In LASEK the epithelium is exposed to 20% alcohol which helps separate epithelium from the cornea. The epithelium is pushed to one side and laser treatment applied. The epithelial layer is replaced back onto the eye and held in place with a contact lens. The contact lens is then removed a few days later. LASEK is hence a "no knife"/flap operation.
Epi-Lasik is a similar procedure that uses a keratome like that used for Lasik, but engineered to only separate the epithelium. The epithelium is left on a hinge, laser treatment applied and flap replaced.
When the hematocrit rises to 60 or 70%, which it often does in polycythemia, the blood viscosity can become as great as 10 times that of water, and its flow through blood vessels is greatly retarded because of increased resistance to flow. This will lead to decreased oxygen delivery.
Thigh pain is most often caused by injuries to bones, joints, muscles, tendons, ligaments, and other soft tissues or blood vessels. These injuries are often caused during sports competition, or strain from overuse, obesity, or pregnancy.
There is a strong association with obesity. In children younger than 10 years, it is associated with metabolic endocrine disorders {hypothyroidism, panhypopituitarism, hypogonadism, renal osteodystrophy, growth hormone abnormalities). SCFE is considered chronic if it has been present more than 3 weeks and acute if it has been present for 3 weeks or less. It is called "stable" if the patient can bear weight and "unstable" if the patient cannot ambulate. Unstable SCFE is associated with more complications, including avascular necrosis of the femoral head (AVN). SCFE is diagnosed by x-ray of the pelvis and bilateral hips. The underlying cause is a widened epiphyseal growth plate, due to abnormal cartilage maturation and endochondral ossification. The treatment is surgical, requiring immediate internal fixation with a single screw. Delay in treatment {> 24 hours) leads to increased AVN, SCFE progression from stable to unstable, and high risk of future degenerative arthritis. Prophylactic contralateral fixation of the unaffected hip is not routinely done in the U.S., except in patients with endocrine abnormalities.
An inguinal hernia occurs when tissue, such as part of the intestine, protrudes through a weak spot in the abdominal muscles. The resulting bulge can be painful, especially when you cough, bend over or lift a heavy object. However, many hernias do not cause pain.
An inguinal hernia isn't necessarily dangerous. It doesn't improve on its own, however, and can lead to life-threatening complications. Your doctor is likely to recommend surgery to fix an inguinal hernia that's painful or enlarging. Inguinal hernia repair is a common surgical procedure.

Squamous cell carcinomas typically appear as persistent, thick, rough, scaly patches that can bleed if bumped, scratched or scraped. They often look like warts and sometimes appear as open sores with a raised border and a crusted surface. In addition to the signs of SCC shown here, any change in a preexisting skin growth, such as an open sore that fails to heal, or the development of a new growth, should prompt an immediate visit to a physician.
Bipolar disorder, also known as manic-depressive illness, is a brain disorder that causes unusual shifts in mood, energy, activity levels, and the ability to carry out day-to-day tasks. There are four basic types of bipolar disorder; all of them involve clear changes in mood, energy, and activity levels.
The condition is caused by a blockage in the lymphatic system, part of the immune and circulatory systems. Lymphedema is most commonly caused by lymph node removal or damage due to cancer treatment. The main symptom is swelling in an arm or leg that may be accompanied by pain or discomfort. Exercise, wrapping, massage, and compression can help.
Detailed examination of the joints is usually not included in the routine medical examination. However, joint related complaints are rather common, and understanding anatomy and physiology of both normal function and pathologic conditions is critically important when evaluating the symptomatic patient. By gaining an appreciation for the basic structures and functioning of the joint, you'll be able to "logic" your way thru the exam, even if you can't remember the eponym attached to each specific test!
