Neurosyphilis is an infection of the brain or spinal cord caused by the spirochete Treponema pallidum. It usually occurs in people who have had chronic, untreated syphilis, usually about 10 to 20 years after first infection and develops in about 25%–40% of persons who are not treated. The United States' Centers for Disease Control and Prevention (CDC) advises that neurosyphilis can occur at any stage of a syphilis infection.
Pyogenic granuloma (lobular capillary hemangioma[1] ) is a relatively common benign vascular lesion of the skin and mucosa whose exact cause is unknown. Also see the Medscape Reference article Oral Pyogenic Granuloma. Pyogenic granulomas are misnamed; they are neither infectious nor granulomatous. The lesion usually occurs in children and young adults as a solitary, glistening red papule or nodule that is prone to bleeding and ulceration. Pyogenic granulomas typically evolve rapidly over a period of a few weeks, most often on the head, neck, extremities, and upper trunk. Pyogenic granuloma often arises in pregnancy (or rarely with oral contraceptive usage), particularly on the gingiva or elsewhere in the oral mucosa, and then is termed the "pregnancy tumor." Other pyogenic granuloma variants that have been well documented include the disseminated, subcutaneous, intravenous, and medication-induced (for example, retinoid, antiretroviral, and oncologic agent) subtypes. Removal of pyogenic granuloma is indicated to alleviate any bleeding, discomfort, cosmetic distress, and diagnostic uncertainty. A number of malignant tumors may clinically mimic pyogenic granuloma, making histopathologic confirmation important if the presentation is atypical. Aside from cutaneous and oral lesions, pyogenic granuloma has been reported throughout the gastrointestinal tract and upper airway, at various ocular locations, the central nervous system, the bladder, and the internal vasculature. This article discusses only cutaneous and oral involvement.
Keep tabs on your blood pressure. If it's too high, your risk of a heart attack and heart disease goes up. Stress management, a healthy diet, and regular exercise can help you manage your blood pressure. Your doctor may also prescribe medications to lower your levels.
Adult Still's disease is a rare type of inflammatory arthritis that features fevers, rash and joint pain. Some people have just one episode of adult Still's disease. In other people, the condition persists or recurs. This inflammation can destroy affected joints, particularly the wrists. Treatment involves medications, such as prednisone, that help control inflammation
Hypertensive emergencies encompass a spectrum of clinical presentations in which uncontrolled blood pressures lead to progressive or impending end-organ dysfunction. In these conditions, the BP should be lowered aggressively over minutes to hours. Neurologic end-organ damage due to uncontrolled BP may include hypertensive encephalopathy, cerebral vascular accident/cerebral infarction, subarachnoid hemorrhage, and/or intracranial hemorrhage.[1] Cardiovascular end-organ damage may include myocardial ischemia/infarction, acute left ventricular dysfunction, acute pulmonary edema, and/or aortic dissection. Other organ systems may also be affected by uncontrolled hypertension, which may lead to acute renal failure/insufficiency, retinopathy, eclampsia, or microangiopathic hemolytic anemia.[1] With the advent of antihypertensives, the incidence of hypertensive emergencies has declined from 7% to approximately 1% of patients with hypertension.[2] In addition, the 1-year survival rate associated with this condition has increased from only 20% (prior to 1950) to a survival rate of more than 90% with appropriate medical treatment
A sleep disorder, or somnipathy, is a medical disorder of the sleep patterns of a person or animal. Some sleep disorders are serious enough to interfere with normal physical, mental, social and emotional functioning. Polysomnography and actigraphy are tests commonly ordered for some sleep disorders.
Your stomach must be empty, so you should not eat or drink anything for approximately 8 hours before the examination. Your physician will be more specific about the time to begin fasting depending on the time of day that your test is scheduled. Your current medications may need to be adjusted or avoided. Most medications can be continued as usual. Medication use such as aspirin, Vitamin E, non-steroidal anti-inflammatories, blood thinners and insulin should be discussed with your physician prior to the examination as well as any other medication you might be taking. It is therefore best to inform your physician of any allergies to medications, iodine, or shellfish. It is essential that you alert your physician if you require antibiotics prior to undergoing dental procedures, since you may also require antibiotics prior to ERCP. Also, if you have any major diseases, such as heart or lung disease that may require special attention during the procedure, discuss this with your physician. To make the examination comfortable, you will be sedated during the procedure, and, therefore, you will need someone to drive you home afterward. Sedatives will affect your judgment and reflexes for the rest of the day, so you should not drive or operate machinery until the next day.
Thoracic outlet syndrome is a group of disorders that occur when blood vessels or nerves in the space between your collarbone and your first rib (thoracic outlet) are compressed. This can cause pain in your shoulders and neck and numbness in your fingers. Common causes of thoracic outlet syndrome include physical trauma from a car accident, repetitive injuries from job- or sports-related activities, certain anatomical defects (such as having an extra rib), and pregnancy. Sometimes doctors can't determine the cause of thoracic outlet syndrome. Treatment for thoracic outlet syndrome usually involves physical therapy and pain relief measures. Most people improve with these approaches. In some cases, however, your doctor may recommend surgery.
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.
The thyroid gland lies in the midline of the anterior neck, just caudal to the thyroid cartilage. To inspect the thyroid gland, the examiner stands in front of the patient. The examiner asks the seated patient to dorsiflex (extend) the neck and swallow a sip of water. Minor enlargement of the gland may only become apparent on inspection in this position. Palpation of the thyroid gland is typically performed with the examiner standing behind the patient. Both lobes and the isthmus of the thyroid gland should be palpated for any nodules or diffuse enlargement. Mobility of the thyroid gland with swallowing should be assessed with palpation. Nodules arising from the thyroid gland typically move with swallowing. A hard, fixed thyroid gland could indicate malignancy. If a central nodule is identified, the patient is asked to protrude the tongue. Upward movement of the central nodule on protrusion of the tongue indicates a thyroglossal cyst. Auscultation is performed at the superior poles of bilateral lobes as this is where the superior thyroid artery is most superficial and bifurcates into its terminal branches. A bilateral bruit over the superior poles suggests Graves disease. Examination of the thyroid gland is completed by palpating the regional cervical lymph nodes for any enlargement.

Masturbating is totally healthy, and totally normal. There are tons of myths out there meant to scare you into thinking masturbation is wrong or bad. But the truth is masturbation is perfectly safe. Masturbating won't make you blind, crazy, or stupid. It won’t damage your genitals, cause pimples, or stunt your growth. It doesn’t use up all your orgasms or ruin other kinds of sex. In fact, masturbation can actually be good for you. Here are some benefits of masturbation: Masturbation is safer than any other type of sex. You can’t get pregnant or get any sexually transmitted infections from masturbating. Masturbation can help you learn what you like and don’t like sexually. And if you decide to have sex with someone, you can know what you do/don’t want to do. BONUS: getting comfortable talking about sex and your body with your partner makes it easier to talk about protecting yourself against STDs and pregnancy, too. Exploring your body and learning how to give yourself sexual pleasure can be empowering and help improve your body image. Masturbation can lower stress and help you relax. It even helps some people fall asleep. Having an orgasm releases endorphins — feel good chemicals in your brain. Orgasms can be a natural painkiller and can even help with period cramps. Mutual masturbation (masturbating with a partner) is a really safe way to have sex and let the other person know what feels good to you. If you share a sex toy, use condoms on the toy and clean it before swapping. And if you touch each other’s genitals, wash your hands before touching your own. Can I get an STD from masturbating? Nope. Masturbating is the safest sexual activity out there. There is virtually NO chance of getting an STD or any other infection from touching your own genitals (and there’s also no chance of pregnancy). STDs have to be passed from one person to another, so you can’t give yourself an STD. The one exception to this is herpes - so if you have any cold sores on your mouth and touch them, make sure to wash your hands before masturbating. But it IS possible to get an STD if you’re masturbating with another person and touching each other’s genitals. Anytime semen (cum) or vaginal fluids are spread to someone else’s body, or your genitals rub against each other, there’s a risk of STDs. So if you touch each other’s genitals, wash your hands before touching your own. STDs can also be spread by sharing sex toys with another person. You can help protect yourself by using condoms on any toys that you share (even if they’re not shaped like a penis). Put a new condom on anytime a different person uses it. If you’re the only one using your sex toys, you don’t have to worry about STDs. But if you use them with other people, protect those sex toys just like you’d protect your own genitals — put a condom on ‘em! It’s possible for masturbation to cause irritation or infections if your body is sensitive to the way you masturbate or the things you masturbate with — but this isn’t the same thing as an STD. Lotions, Vaseline, oils, and scented or flavored stuff may irritate your vulva and vagina. Masturbating roughly and not using lubrication can also lead to irritation because of friction. And germs from the anus can cause vaginal infections — so never put something in your vagina that’s been in your butt without washing it or covering it with a condom. If you’re worried that you have an STD because of pain, itching, or discomfort in your genitals, go to your doctor or your local Planned Parenthood health center.
Acute mesenteric ischemia (AMI) is a syndrome caused by inadequate blood flow through the mesenteric vessels, resulting in ischemia and eventual gangrene of the bowel wall. Although relatively rare, it is a potentially life-threatening condition. Broadly, AMI may be classified as either arterial or venous. AMI as arterial disease may be subdivided into nonocclusive mesenteric ischemia (NOMI) and occlusive mesenteric arterial ischemia (OMAI); OMAI may be further subdivided into acute mesenteric arterial embolism (AMAE) and acute mesenteric arterial thrombosis (AMAT). AMI as venous disease takes the form of mesenteric venous thrombosis (MVT).
Signs and symptoms of colon cancer include: A change in your bowel habits, including diarrhea or constipation or a change in the consistency of your stool, that lasts longer than four weeks Rectal bleeding or blood in your stool Persistent abdominal discomfort, such as cramps, gas or pain A feeling that your bowel doesn't empty completely Weakness or fatigue Unexplained weight loss Many people with colon cancer experience no symptoms in the early stages of the disease. When symptoms appear, they'll likely vary, depending on the cancer's size and location in your large intestine.
