Giant cell arteritis is an inflammation of the lining of your arteries. Most often, it affects the arteries in your head, especially those in your temples. For this reason, giant cell arteritis is sometimes called temporal arteritis. Giant cell arteritis frequently causes headaches, scalp tenderness, jaw pain and vision problems. If left untreated, it can lead to stroke or blindness. Prompt treatment with corticosteroid medications usually relieves symptoms of giant cell arteritis and may prevent loss of vision. You'll likely begin to feel better within days of starting treatment. But even with treatment, relapses are common. You'll need to visit your doctor regularly for checkups and treatment of any side effects from taking corticosteroids.
Pelvic inflammatory disease (PID) is an infection of the female reproductive organs. It usually occurs when sexually transmitted bacteria spread from your vagina to your uterus, fallopian tubes or ovaries. Many women who develop pelvic inflammatory disease either experience no signs or symptoms or don't seek treatment. Pelvic inflammatory disease may be detected only later when you have trouble getting pregnant or if you develop chronic pelvic pain.
Ventricular tachycardia is a type of heart rhythm disorder (arrhythmia) in which the lower chambers of your heart (ventricles) beat very quickly because of a problem in your heart's electrical system. In ventricular tachycardia, your heart may not be able to pump enough blood to your body and lungs because the chambers are beating so fast that they don't have time to properly fill. Ventricular tachycardia may be brief — lasting for just seconds and often not causing symptoms — or it can last for much longer, and you can develop symptoms such as dizziness or lightheadedness, or you can even pass out. This condition usually occurs in people with other heart conditions, such as coronary artery disease, cardiomyopathy and some types of valvular heart disease. Ventricular tachycardia may lead to a condition in which your lower heart chambers quiver (ventricular fibrillation), which may cause your heart to stop (sudden cardiac arrest) and lead to death if not treated immediately. Ventricular tachycardia can also cause your heart to stop, especially if the heart is beating very quickly, if it's lasting for a long period, and if you have an underlying heart condition.
Bell's palsy is a form of facial paralysis resulting from damage or trauma to the facial nerves. The facial nerve-also called the 7th cranial nerve-travels through a narrow, bony canal (called the Fallopian canal) in the skull, beneath the ear, to the muscles on each side of the face. For most of its journey, the nerve is encased in this bony shell. Each facial nerve directs the muscles on one side of the face, including those that control eye blinking and closing, and facial expressions such as smiling and frowning. Additionally, the facial nerve carries nerve impulses to the lacrimal or tear glands, the saliva glands, and the muscles of a small bone in the middle of the ear called the stapes. The facial nerve also transmits taste sensations from the tongue. When Bell's palsy occurs, the function of the facial nerve is disrupted, causing an interruption in the messages the brain sends to the facial muscles. This interruption results in facial weakness or paralysis. Bell's palsy is named for Sir Charles Bell, a 19th century Scottish surgeon who described the facial nerve and its connection to the condition. The disorder, which is not related to stroke, is the most common cause of facial paralysis. Generally, Bell's palsy affects only one of the paired facial nerves and one side of the face, however, in rare cases, it can affect both sides.

A chronic cough is a cough that lasts eight weeks or longer in adults, or four weeks in children. A chronic cough is more than just an annoyance. A chronic cough can interrupt your sleep and leave you feeling exhausted. Severe cases of chronic cough can cause vomiting, lightheadedness and even rib fractures. While it can sometimes be difficult to pinpoint the problem that's triggering a chronic cough, the most common causes are tobacco use, postnasal drip, asthma and acid reflux. Fortunately, chronic cough typically disappears once the underlying problem is treated.
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.
The epididymis is a long coiled tube that lies above and behind each testicle. The epididymis collects and transports sperm from the testis to the vas deferens (tubes that transport sperm to the urethra). An epididymal cyst is a cyst-like mass in the epididymis that contains clear fluid. Typically, epididymal cysts and spermatoceles do not cause symptoms. When discovered, the epididymal cyst is usually about the size of a pea and feels separate from the top of the testis. Spermatoceles typically arise from the head of the epididymis, and are felt on the top portion of the testicle. Epididymal cysts and spermatoceles are often incidental findings on testicular self-examination or routine physical examination. It is important that any mass noted in the scrotum be examined by a urologist in order to obtain an accurate diagnosis, especially a mass on the testicle itself. Our team in the Division of Urology will typically be able to confirm the diagnosis on physical exam. However, a scrotal ultrasound may also be used in order to rule out other conditions.
