Pink eye (conjunctivitis) is an inflammation or infection of the transparent membrane (conjunctiva) that lines your eyelid and covers the white part of your eyeball. When small blood vessels in the conjunctiva become inflamed, they're more visible. This is what causes the whites of your eyes to appear reddish or pink. Pink eye is commonly caused by a bacterial or viral infection or an allergic reaction. It may affect one or both eyes. Pink eye can be irritating, but it rarely affects your vision. Treatments can help ease the discomfort of pink eye. Because pink eye can be contagious, early diagnosis and treatment can help limit its spread.

The increased risk of thrombosis in patients with active cancer has multiple causes. Acute thrombosis of the aorta is an exceedingly rare but potentially devastating complication in patients with cancer receiving cisplatin-based chemotherapy. Prompt diagnosis and definitive treatment are imperative to decrease morbidity and mortality. Early diagnosis is difficult because initial presentation is often nonspecific, requiring a high degree of clinical suspicion. We report 4 cases of acute thrombosis of the abdominal aorta in patients with cancer receiving cisplatin-based chemotherapy. We review the clinical aspects, recommended investigation, and treatment of this potentially fatal complication.

Back pain during pregnancy is a common complaint — and it's no wonder. You're gaining weight, your center of gravity changes, and your hormones are relaxing the ligaments in the joints of your pelvis. Often, however, you can prevent or ease back pain during pregnancy. Consider seven ways to give pregnancy back pain the boot. 1. Practice good posture As your baby grows, your center of gravity shifts forward. To avoid falling forward, you might compensate by leaning back — which can strain the muscles in your lower back and contribute to back pain during pregnancy. Keep these principles of good posture in mind: Stand up straight and tall. Hold your chest high. Keep your shoulders back and relaxed. Don't lock your knees. When you stand, use a comfortably wide stance for the best support. If you must stand for long periods of time, rest one foot on a low step stool — and take time for frequent breaks. Good posture also means sitting with care. Choose a chair that supports your back, or place a small pillow behind your lower back. 2. Get the right gear Wear low-heeled — not flat — shoes with good arch support. Avoid high heels, which can further shift your balance forward and cause you to fall. You might also consider wearing a maternity support belt. Although research on the effectiveness of maternity support belts is limited, some women find the additional support helpful. 3. Lift properly When lifting a small object, squat down and lift with your legs. Don't bend at the waist or lift with your back. It's also important to know your limits. Ask for help if you need it. 4. Sleep on your side Sleep on your side, not your back. Keep one or both knees bent. Consider using pregnancy or support pillows between your bent knees, under your abdomen and behind your back.

Clopidogrel keeps the platelets in your blood from coagulating (clotting) to prevent unwanted blood clots that can occur with certain heart or blood vessel conditions. Clopidogrel is used to prevent blood clots after a recent heart attack or stroke, and in people with certain disorders of the heart or blood vessels. Clopidogrel may also be used for other purposes not listed in this medication guide

Fibrodysplasia ossificans progressiva (FOP) is a disorder in which muscle tissue and connective tissue such as tendons and ligaments are gradually replaced by bone (ossified), forming bone outside the skeleton (extra-skeletal or heterotopic bone) that constrains movement. This process generally becomes noticeable in early childhood, starting with the neck and shoulders and proceeding down the body and into the limbs. Extra-skeletal bone formation causes progressive loss of mobility as the joints become affected. Inability to fully open the mouth may cause difficulty in speaking and eating. Over time, people with this disorder may experience malnutrition due to their eating problems. They may also have breathing difficulties as a result of extra bone formation around the rib cage that restricts expansion of the lungs.

In nonsurgical treatment, progressive physical therapy and rehabilitation can restore the knee to a condition close to its pre-injury state and educate the patient on how to prevent instability.37, 38 This may be supplemented with the use of a hinged knee brace. However, many people who choose not to have surgery may experience secondary injury to the knee due to repetitive instability episodes. Surgical treatment is usually advised in dealing with combined injuries (ACL tears in combination with other injuries in the knee). However, deciding against surgery is reasonable for select patients. Nonsurgical management of isolated ACL tears is likely to be successful or may be indicated in patients:

Spina bifida is a type of birth defect called a neural tube defect. It occurs when the bones of the spine (vertebrae) don't form properly around part of the baby's spinal cord. Spina bifida can be mild or severe. The mild form is the most common.

A leg ulcer is simply a break in the skin of the leg, which allows air and bacteria to get into the underlying tissue. This is usually caused by an injury, often a minor one that breaks the skin. In most people such an injury will heal up without difficulty within a week or two. However, when there is an underlying problem the skin does not heal and the area of breakdown can increase in size. This is a chronic leg ulcer.

-MEN1 syndrome is composed of hyperparathyroidism, gastrinoma (pancreatic tumor) and pituitary tum or(remember the 3 Ps). Hyperparathyroidism in MEN1 is caused by hyperplasia of the parathyroid glands. Removal of 3 1/2 glands or total parathyroidectomy with autotransplantation is necessary.

Papillary fibroelastoma is the third most common primary tumor of the heart and is most likely to involve the cardiac valves. Like myxomas, they arise from the endocardium in most patients and since these tumors are often incidental findings at echocardiography or autopsy, the true incidence is difficult to estimate. Most patients are older than 60 years, which also contrasts with myxomas. Papillary fibroelastomas can embolize, leading to severe neurological complications and therefore, surgical removal is advised, although there is controversy regarding small incidental lesions and the need for surgery.
