Chicken Pox Rash

Wed 17 Feb 2016 19:59:00 +0200

Chickenpox is caused by the varicella zoster virus, which is very contagious. If you haven't had chickenpox before and someone you come into prolonged contact with has it, you're likely to catch it too.

The virus is usually transferred from person to person through the air in the fine spray of saliva or mucous droplets when you cough or sneeze. It can also be passed from person to person through contact with the fluid from chickenpox blisters, either from a person who is infected or by items such as clothing that have been in contact with broken blisters.

If you have chickenpox, you can pass the virus on about one to two days before the rash breaks out. You'll remain infectious until your spots have crusted over, usually five to six days after the illness starts. Avoid contact with others and keep infected children at home away from school or day care during this time.

Once you've had chickenpox, you will usually be immune and probably won't catch it again. However, it is possible to become re-infected. The virus can also remain dormant in your body, even after symptoms have cleared, and cause shingles later in life.

If you've never had chickenpox before, it's possible to get chickenpox from someone who has shingles, through contact with fluid from the shingles rash. However, it's not possible to catch shingles from someone who has chickenpox.

Chicken Pox Virus

Mon 15 Feb 2016 15:24:00 +0200

Chickenpox is a highly contagious illness caused by the varicella-zoster virus (VZV), a type of herpes virus. It is often a mild illness, characterized by an itchy rash on the face, scalp and trunk with pink spots and tiny fluid-filled blisters that dry and become scabs four to five days later. Serious complications, although rare, can occur mainly in infants, adolescents, adults and persons with a weakened immune system. These complications include bacterial infections of skin blisters, pneumonia, and encephalitis (inflammation of the brain). In temperate climates, such as the Northeast, chickenpox occurs most frequently in the late winter and early spring.

Chickenpox is a common childhood illness with 90 percent of the cases occurring in children younger than ten years of age. Before the availability of the varicella vaccine in the U.S., almost everyone developed chickenpox. Most people who are vaccinated will not get chickenpox. Those who are vaccinated and develop chickenpox usually have a mild form of the illness. They have fewer spots and recover faster.

Chickenpox is transmitted from person to person by directly touching the blisters, saliva or mucus of an infected person. The virus can also be transmitted through the air by coughing and sneezing. Chickenpox can be spread indirectly by touching contaminated items freshly soiled, such as clothing, from an infected person. Direct contact with the blisters of a person with shingles can cause chickenpox in a person who has never had chickenpox and has not been vaccinated. Blisters that are dry and crusted are no longer able to spread chickenpox.

Initial symptoms include sudden onset of slight fever and feeling tired and weak. These are soon followed by an itchy blister-like rash. The blisters eventually dry, crust over and form scabs. The blisters tend to be more common on covered than on exposed parts of the body. They may appear on the scalp, armpits, trunk and even on the eyelids and in the mouth. Mild or asymptomatic infections occasionally occur in children. The disease is usually more serious in young infants and adults than in children.

Symptoms commonly appear 14 to 16 days (range of ten to 21 days) after exposure to someone with chickenpox or herpes zoster (shingles).

Chicken Pox in Infants

Mon 15 Feb 2016 15:23:00 +0200

Chickenpox is a very infectious illness caused by one of a group of herpes viruses. It causes a distinctive rash and mild flu-like symptoms.

Most children will get chickenpox when they are young and it is usually a mild illness. Once your baby has caught the virus, it can take between 10 days and 21 days for symptoms to show. Your baby will then be infectious from about two days before the rash appears until all the spots have dried up. This usually takes about five days. If your baby goes to nursery or childcare, keep him at home for five days from when the rash first appears.

An infected person sneezing or being in close contact with your baby could have given him chickenpox. Your baby could also have got chickenpox just by being in the same room as someone with the virus.

It’s also possible to catch chickenpox from someone who has shingles. Shingles is caused by the same virus as chickenpox.

Chickenpox usually starts with mild flu-like symptoms:
fever
headache
nausea
aches and pains
loss of appetite

A couple of days later, the chickenpox rash appears. It starts as little red spots that develop tiny blisters on the top within a few hours. You’ll notice them first on your baby’s face. The spots will spread to his chest and tummy, and then to other parts of his body, appearing in crops.

There may be so many spots that they will appear to run into one another, or there may just be a few spots. The spots are likely to be most sore on his scalp, in his mouth and throat, and around his genitals.

Herpes Symptoms in Men

Mon 15 Feb 2016 15:08:00 +0200

Genital herpes symptoms in men can range from so mild that they go unnoticed by the affected man, to severe outbreaks on the skin surface. Symptoms usually appear within two days to two weeks of first exposure to the virus, but this isn’t always the case as some people have it for a long time before seeing the signs.

Herpes outbreaks in men tend to show up as blisters on the tip or shaft of the penis (as opposed to the base), the inner thighs and buttocks. Homosexual men may also get blisters around the anus. These outbreaks are highly contagious if they come into contact with someone’s skin.

Milder symptoms of herpes in men can include fever, fatigue, headache, muscle pain, difficulty urinating, and chills.

Symptoms of Herpes

Mon 15 Feb 2016 15:07:00 +0200

The virus starts to multiply when it gets into the skin cells. The skin becomes red and sensitive, and soon afterward, one or more blisters or bumps appear. The blisters first open, scab over, and then heal as new skin tissue forms. During a first outbreak, the area is usually painful and may itch, burn or tingle. Flu-like symptoms are also common. These include swollen glands, headache, muscle ache, lower back pain, and fever. Herpes may also infect the urethra, and urinating may cause a burning sensation.

People diagnosed with herpes can expect to have several, typically four or five, outbreaks within a year. As time passes, these recurrences usually decrease in frequency. Herpes recurrences vary individually.

Erysipelas Leg

Mon 15 Feb 2016 14:51:00 +0200

Erysipelas is often of sudden onset, marked by frank systemic signs—fever >38°5, chills—and general malaise. Patients with lymphedema, who present with recurrent episodes of erysipelas, often recognize these inaugural signs. Local signs develop within a few hours: a red, warm, painful, inflammatory spreading lesion, with centrifugal extension within a few days. Erysipelas can start at any point of lymphedema and can extend to all or part of the lymphedematous cutaneous tissue, in an anterograde or retrograde pattern. Inflammatory, satellite adenopathy and lymphangitis are associated with erysipelas in 25% to 50% of cases.

In the case of erysipelas complicating lymphedema, the clinical presentation is more serious. Statistically significant differences (P<0.05) were seen between 20 controls with erysipelas but without lymphedema and 10 age- and sex-matched patients with lymphedema hospitalized for erysipelas: prolonged persistence of fever, more frequent tachycardia, delayed recovery, and positive blood cultures (30% vs 0%).

The diagnosis of erysipelas is clinical: sudden occurrence of an inflammatory lesion that spreads within a few days, preceded by or concomitant with fever and chills, and general malaise. No bacterium other than ß-hemolytic streptococcus has been demonstrated as responsible for erysipelas. Streptococcus was isolated 15 times more often in lymphedema with an infectious complication than outside any acute inflammatory episode, and serology testing for streptococcus (ASLO) was more often positive in patients with lymphedema (78%) than in a healthy control population (46%). Bacteriological samples are positive in erysipelas in only 4% to 35% of cases with standard methods. Using the most sophisticated methods (immunofluorescence, polymerase chain reaction), streptococcus is isolated at a frequency of 70% to 80%.5 Other bacteria (Staphylococcus aureus, Enterobacteriaceae, Pseudomonas) have been isolated alone or in combination with streptococcus. But to date a causal relationship has never been demonstrated.

Furthermore, these bacteria are commonly found on skin and colonize wounds, and their isolation from samples collected from the skin is difficult to interpret. Laboratory tests are not helpful in establishing the diagnosis: the complete blood count shows leukocytosis in one-half of cases, and a nonspecific inflammatory syndrome is indicated by laboratory findings in two-thirds of cases.

Define Erysipelas

Mon 15 Feb 2016 14:50:00 +0200

Erysipelas is a nonnecrotizing bacterial hypodermal cellulitis usually associated with streptococcal infection. It may be a mainly secondary complication of chronic lymphedema, and occurs in 20% to 30% of cases. The first presenting signs are sudden fever and shivering. The clinical feature is inflammatory plaque, which is often chronic and accompanied by fever. Inflammatory plaque is promoted by lymph stasis, and is marked by inflammatory episodes that often regress spontaneously. Erysipelas per se is mainly treated with antibiotics, and adjuvant therapies are not justified. The prevention of recurrence is primary. Since lymphedema is the first risk factor for recurrence, its treatment and risk of occurrence must be considered. This includes physiotherapy, well-adapted compression therapy, and avoidance of wounds.

The lymphatic system has a role in antigen presentation and defense against infection. Infection is the most common type of complication observed in lymphedema, and is promoted by lymphatic system dysfunction, which causes locoregional immune disorders. Infectious complications are primarily bacterial, and most commonly are erysipelas (cellulitis) and sometimes lymphangitis. ß-hemolytic streptococcus (groups A, C, G) is the organism usually (and even almost exclusively) observed in everyday practice. Bacterial complications are promoted by the abundance of proteins characteristic of edema in lymphatic insufficiency related to obstructed lymphatic vessels. This high protein content of the interstitial fluid is an ideal culture medium for the growth of bacteria.

Erysipelas Face

Mon 15 Feb 2016 14:48:00 +0200

Erysipelas contagious infection of the skin and underlying tissue, caused by group A B-hemolytic streptococcus bacteria. Erysipelas causes affected areas of skin to turn bright red and become slightly swollen. The swollen blotches have a distinct border and slowly expand into the surrounding skin. The lesions are most commonly seen on the face, scalp, hands, and legs. They feel hot to the touch and the patient is feverish.

Erysipelas Definition

Mon 15 Feb 2016 14:47:00 +0200

Erysipelas is an infection of the upper layers of the skin (superficial). The most common cause is group A streptococcal bacteria, especially Streptococcus pyogenes. Erysipelas results in a fiery red rash with raised edges that can easily be distinguished from the skin around it. The affected skin may be warm to the touch. At one time, erysipelas was thought to affect mostly the face, but recent studies suggest that the distribution of the inflammation is changing since at the present time the legs are involved in almost 80% of cases. The rash may also appear on the arms or trunk. Erysipelas begins with minor trauma, such as a bruise, burn, wound, or incision. When the rash appears on the trunk, arms, or legs, it is usually at the site of a surgical incision or a wound.

Erysipelas usually first appears as a localized lesion that is tender and red. The lesion quickly develops a bright red, shiny color and a spreading, raised border. The typical lesion is so characteristic that its presence is diagnostic. The lesion may feel hot and be painful. There may be accompanying high fever, chills, headache, nausea, and a general feeling of ill health (malaise). The skin in the affected area may resemble the peel of an orange. In infants, erysipelas may appear on the abdomen due to infection of the umbilical cord. In children and adults, erysipelas most commonly develops on the legs, arms and face. Erysipelas may also develop at sites of minor surgery or trauma, or it may be due to lymphatic obstruction.

Erysipelas is caused by one of several strains of streptococcus bacteria, or less frequently by a staphylococcus infection. Streptococci are involved in about 80% of cases.

Erysipelas on Face Symptoms

Mon 15 Feb 2016 14:43:00 +0200

Erysipelas is a bacterial infection of the skin and subcutaneous tissue, usually involving the face, ears and lower legs. It is characterized by well demarcated areas of redness, heat, pain, and swelling and may be associated with constitution symptoms including fever, chills, headache, joint pain, and back pain.

Predisposing factors of erysipelas are operative wounds, scrapes, or abrasions of the skin. The onset is usually abrupt with high fever, chills, and weakness. Over the next 24- 48 hours a red shiny plaque forms usually proximal to the area of entry into the skin. A dermatologist can usually make a diagnosis by examining the patient but sometimes other tests including bacterial skin culture, white blood cell count and blood cultures may be needed. In adults, Group A streptococcal bacterial infection is the most common cause and in children Hemophilus influenza bacterial infection is the most common cause.

Pemphigus Children

Sun 14 Feb 2016 01:17:00 +0200

Pemphigus is characterized by blisters on your skin and mucous membranes. The blisters rupture easily, leaving open sores, which may ooze and become infected. The signs and symptoms of the two main types of pemphigus are as follows:
Pemphigus vulgaris. This type usually begins with blisters in your mouth and then on your skin or genital mucous membranes. The blisters typically are painful, but don't itch. Blisters in your mouth or throat may make it hard to swallow and eat.
Pemphigus foliaceus. This type doesn't usually affect mucous membranes. And the blisters tend not to be painful. This condition may affect any skin, but most blisters are on the chest, back and shoulders. The blisters cause the skin to be crusty and itchy.

Pemphigus is an autoimmune disorder. It's not contagious. In most cases, it's unknown what triggers the disease. Normally, your immune system attacks foreign invaders, such as harmful viruses and bacteria. But in pemphigus, your immune system mistakenly produces antibodies that attack healthy cells in your skin and mucous membranes. Rarely, pemphigus develops as a side effect of medications, such as certain blood pressure drugs. This type of pemphigus usually disappears when the medicine is stopped.

Pemphigus Disease

Sat 13 Feb 2016 23:13:00 +0200

Pemphigus is a rare group of blistering autoimmune diseases that affect the skin and mucous membranes. In pemphigus, autoantibodies form against desmoglein. Desmoglein forms the "glue" that attaches adjacent epidermal cells via attachment points called desmosomes. When autoantibodies attack desmogleins, the cells become separated from each other and the epidermis becomes "unglued", a phenomenon called acantholysis. This causes blisters that slough off and turn into sores. In some cases, these blisters can cover a significant area of the skin.

Originally, the cause of this disease was unknown, and "pemphigus" was used to refer to any blistering disease of the skin and mucosa. In 1964, researchers found that the blood of patients with pemphigus contained antibodies to the layers of skin that separates to form the blisters. In 1971, an article investigating the autoimmune nature of this disease was published.
