Shingles is a viral infection that causes a painful rash. Although shingles can occur anywhere on your body, it most often appears as a single stripe of blisters that wraps around either the left or the right side of your torso. Shingles is caused by the varicella-zoster virus — the same virus that causes chickenpox. After you've had chickenpox, the virus lies inactive in nerve tissue near your spinal cord and brain. Years later, the virus may reactivate as shingles. While it isn't a life-threatening condition, shingles can be very painful. Vaccines can help reduce the risk of shingles, while early treatment can help shorten a shingles infection and lessen the chance of complications.

Primary infection with herpes simplex viruses (HSVs) is clinically more severe than recurrent outbreaks. However, most primary HSV-1 and HSV-2 infections are subclinical and may never be clinically diagnosed. Orolabial herpes Herpes labialis (eg, cold sores, fever blisters) is most commonly associated with HSV-1 infection. Oral lesions caused by HSV-2 have been identified, usually secondary to orogenital contact. Primary HSV-1 infection often occurs in childhood and is usually asymptomatic. Primary infection Symptoms of primary herpes labialis may include a prodrome of fever, followed by a sore throat and mouth and submandibular or cervical lymphadenopathy. In children, gingivostomatitis and odynophagia are also observed. Painful vesicles develop on the lips, the gingiva, the palate, or the tongue and are often associated with erythema and edema. The lesions ulcerate and heal within 2-3 weeks. Recurrences The disease remains dormant for a variable amount of time. HSV-1 reactivation in the trigeminal sensory ganglia leads to recurrences in the face and the oral, labial, and ocular mucosae. Pain, burning, itching, or paresthesia usually precedes recurrent vesicular lesions that eventually ulcerate or form a crust. The lesions most commonly occur in the vermillion border, and symptoms of untreated recurrences last approximately 1 week. Recurrent erythema multiforme lesions have been associated with orolabial HSV-1 recurrences. A recent study reported that HSV-1 viral shedding had a median duration of 48-60 hours from the onset of herpes labialis symptoms. They did not detect any virus beyond 96 hours of symptom onset.[7] Genital herpes HSV-2 is identified as the most common cause of herpes genitalis. However, HSV-1 has been increasingly identified as the causative agent in as many as 30% of cases of primary genital herpes infections likely secondary to orogenital contact. Recurrent genital herpes infections are almost exclusively caused by HSV-2. Primary infection Primary herpes genitalis occurs within 2 days to 2 weeks after exposure to the virus and has the most severe clinical manifestations. Symptoms of the primary episode typically last 2-3 weeks. In men, painful, erythematous, vesicular lesions that ulcerate most commonly occur on the penis, but they can also occur on the anus and the perineum. In women, primary herpes genitalis presents as vesicular/ulcerated lesions on the cervix and as painful vesicles on the external genitalia bilaterally. They can also occur on the vagina, the perineum, the buttocks, and, at times, the legs in a sacral nerve distribution. Associated symptoms include fever, malaise, edema, inguinal lymphadenopathy, dysuria, and vaginal or penile discharge. Females may also have lumbosacral radiculopathy, and as many as 25% of women with primary HSV-2 infections may have associated aseptic meningitis. Recurrences After primary infection, the virus may be latent for months to years until a recurrence is triggered. Reactivation of HSV-2 in the lumbosacral ganglia leads to recurrences below the waist. Recurrent clinical outbreaks are milder and often preceded by a prodrome of pain, itching, tingling, burning, or paresthesia. Individuals who are exposed to HSV and have asymptomatic primary infections may experience an initial clinical episode of genital herpes months to years after becoming infected. Such an episode is not as severe as a true primary outbreak. More than one half of individuals who are HSV-2 seropositive do not experience clinically apparent outbreaks. However, these individuals still have episodes of viral shedding and can transmit the virus to their sexual partners. Other HSV infections Localized or disseminated eczema herpeticum is also known as Kaposi varicelliform eruption. Caused by HSV-1, eczema herpeticum is a variant of HSV infection that commonly develops in patients with atopic dermatitis, burns, or other inflammatory skin conditions. Children are most commonly affected. Herpes whitlow, vesicular outbreaks on the hands and the digits, was most commonly due to infection with HSV-1. It usually occurred in children who sucked their thumbs and, prior to the widespread use of gloves, in dental and medical health care workers. The occurrence of herpes whitlow due to HSV-2 is increasingly recognized, probably due to digital-genital contact. Herpes gladiatorum is caused by HSV-1 and is seen as papular or vesicular eruptions on the face, arms, or torsos of athletes in sports involving close physical contact (classically wrestling). Disseminated HSV infection can occur in females who are pregnant and in individuals who are immunocompromised. These patients may present with atypical signs and symptoms of HSV, and the condition may be difficult to diagnose. Herpetic sycosis, a follicular infection with HSV, may present as a vesiculopustular eruption on the beard area. This infection often results from autoinoculation after shaving through a recurrent herpetic outbreak. Classically caused by HSV-1, there have been rare reports of relapsing beard folliculitis caused by type 2 HSV.[8] Neonatal HSV HSV-2 infection in pregnancy can have devastating effects on the fetus. Neonatal HSV usually manifests within the first 2 weeks of life and clinically ranges from localized skin, mucosal, or eye infections to encephalitis, pneumonitis, disseminated infection, and demise. Most women who deliver infants with neonatal HSV had no prior history, signs, or symptoms of HSV infection. Risk of transmission is highest in pregnant women who are seronegative for both HSV-1 and HSV-2 and acquire a new HSV infection in the third trimester of pregnancy. Factors that increase the risk of transmission from mother to baby include the type of genital infection at the time of delivery (higher risk with active primary infection), active lesions, prolonged rupture of membranes, vaginal delivery, and an absence of transplacental antibodies. The mortality rate for neonates is extremely high (>80%) if untreated.

Very small currents can be imperceptible. Larger current passing through the body may make it impossible for a shock victim to let go of an energized object. Still larger currents can cause fibrillation of the heart and damage to tissues. Death caused by an electric shock is called electrocution.

U.S. biotech firm Bioquark recently got approval to move forward with its ReAnima Project, in which it will try to reverse brain death in patients on life support

Acute bronchitis and pneumonia share many of the same symptoms, and some people with acute bronchitis are at risk for getting pneumonia. Although acute bronchitis usually goes away within a few weeks, pneumonia can be a serious condition, especially in older adults. The following table outlines some differences between acute bronchitis and pneumonia. There are variations in symptoms of both conditions, so if you think you might have pneumonia, always check with your doctor.

Men need to know that breast cancer is not limited to women. Possible symptoms of breast cancer to watch for include: A lump or swelling, which is usually (but not always) painless Skin dimpling or puckering Nipple retraction (turning inward) Redness or scaling of the nipple or breast skin Discharge from the nipple Sometimes a breast cancer can spread to lymph nodes under the arm or around the collar bone and cause a lump or swelling there, even before the original tumor in the breast tissue is large enough to be felt. These changes aren't always caused by cancer. For example, most breast lumps in men are caused by gynecomastia (a harmless enlargement of breast tissue). Still, if you notice any breast changes, you should see a health care professional as soon as possible.

Epley maneuver: Step 1 You will sit on the doctor's exam table with your legs extended in front of you. The doctor will turn your head so that it is halfway between looking straight ahead and looking directly to the side that causes the worst vertigo. Without changing your head position, the doctor will guide you back quickly so that your shoulders are on the table but your head is hanging over the edge of the table. In this position, the side of your head that is causing the worst vertigo is facing the floor. The doctor will hold you in this position for 30 seconds or until your vertigo stops. Epley maneuver: Step 2 Then, without lifting up your head, the doctor will turn your head to look at the same angle to the opposite side, so that the other side of your head is now facing the floor. The doctor will hold you in this position for 30 seconds or until your vertigo stops. Epley maneuver: Step 3 The doctor will help you roll in the same direction you are facing so that you are now lying on your side. (For example, if you are looking to your right, you will roll onto your right side.) The side that causes the worst vertigo should be facing up. The doctor will hold you in this position for another 30 seconds or until your vertigo stops. Epley maneuver: Step 4 The doctor will then help you to sit back up with your legs hanging off the table on the same side that you were facing. This maneuver is done with the assistance of a doctor or physical therapist. A single 10- to 15-minute session usually is all that is needed. When your head is firmly moved into different positions, the crystal debris (canaliths) causing vertigo will move freely and no longer cause symptoms.

An omphalocele is a birth defect in which an infant's intestine or other abdominal organs are outside of the body because of a hole in the belly button (navel) area. The intestines are covered only by a thin layer of tissue and can be easily seen.

Genital warts are soft growths that appear on the genitals. Genital warts are a sexually transmitted infection (STI) caused by certain strains of the human papillomavirus (HPV). These skin growths can cause pain, discomfort, and itching. They are especially dangerous for women because some types of HPV can also cause cancer of the cervix and vulva.

Pulmonary embolism symptoms can vary greatly, depending on how much of your lung is involved, the size of the clots, and whether you have underlying lung or heart disease. Common signs and symptoms include: Shortness of breath. This symptom typically appears suddenly and always gets worse with exertion. Chest pain. You may feel like you're having a heart attack. The pain may become worse when you breathe deeply (pleurisy), cough, eat, bend or stoop. The pain will get worse with exertion but won't go away when you rest. Cough. The cough may produce bloody or blood-streaked sputum. Other signs and symptoms that can occur with pulmonary embolism include: Leg pain or swelling, or both, usually in the calf Clammy or discolored skin (cyanosis) Fever Excessive sweating Rapid or irregular heartbeat Lightheadedness or dizziness

Researchers have received approval to bring 20 brain-dead humans back to life.

What is tropical sprue? Tropical sprue is diagnosed when somebody has long-standing GI problems and has visited tropical regions in the past. It's thought to be caused by bacterial overgrowth and often leads to villous atrophy.

Nosebleeds are common. Most often they are a nuisance and not a true medical problem. But they can be both. Nosebleed care Sit upright and lean forward. By remaining upright, you reduce blood pressure in the veins of your nose. This discourages further bleeding. Sitting forward will help you avoid swallowing blood, which can irritate your stomach. Pinch your nose. Use your thumb and index finger to pinch your nostrils shut. Breathe through your mouth. Continue to pinch for five to 10 minutes. Pinching sends pressure to the bleeding point on the nasal septum and often stops the flow of blood. To prevent re-bleeding, don't pick or blow your nose and don't bend down for several hours after the bleeding episode. During this time remember to keep your head higher than the level of your heart. If re-bleeding occurs, blow out forcefully to clear your nose of blood clots and spray both sides of your nose with a decongestant nasal spray containing oxymetazoline (Afrin, Mucinex Moisture Smart, others). Pinch your nose again as described above and call your doctor. When to seek emergency care The bleeding lasts for more than 20 minutes The nosebleed follows an accident, a fall or an injury to your head, including a punch in the face that may have broken your nose
