Scabies is one of a number of skin conditions which can trigger itching and rashes. It is a dermatological condition caused by eight-legged microscopic mite, the sarcoptes scabiei.
Scabies is contagious, and can easily spread by direct physical contact from person to person. This is likely to cause an outbreak in settings such as the family home, child care setting, school class, home nursing, or prison.
It can affect people of all ages, however, whatever their lifestyle and socioeconomic status. If an person has scabies, they must all be treated together, and anyone they have close contact with.
Fast facts on scabies
Here are a few key points about the scabies. The main article includes more specifics and supporting information.
- While the scabies mite needs skin to feed and survive, it can live without a human host for 48 to 72 hours.
- The rash and itching experienced by those with scabies is a result of the body’s allergic reaction to the mites, their eggs, and their waste.
- The average person infested with scabies will have 15 to 20 mites present.
- Those at highest risk of developing crusted scabies include the immunocompromised, the elderly, and those housed in institutional settings.
What is scabies?
Scabies affect millions of people every year, from all races, ages and socioeconomic status.
It is highly contagious, being quickly spread by close physical contact and sharing of mite-infested bedding, clothing and furniture.
It is estimated that Scabies infects more than 300 million people worldwide every year, including 1 million people in the US.
Scabies most commonly occurs in children and young adults, and outbreaks are common in child care facilities and schools.
The onset of scabies signs varies depending on whether a person has been previously exposed to the mites or not. It may take up to 2-6 weeks for symptoms to develop when a person is first exposed to the scabies mite.
In subsequent infestations, this timeframe is significantly shorter, as the body’s immune system responds quicker, usually within 1 to 4 days.
Symptoms and Scabies symptoms include:
- Itching: Often at night this is worse, and can be intense and painful. Itching constitutes one of the most common symptoms of scabies.
- Rash: When the mite burrows into the skin, it makes burrow tracks or lines that are most commonly found in skin folds and mimic scaly skin patches, hives, scratches, knots, pimples. There may also be Blisters.
- Sores: These occur in places that are infested where a person has scratched his skin. Open sores can lead to imppetigo, which is usually caused by Staphylococcus aureus secondary infection.
- Thick crusts: Crusted scabies, also known as Norwegian scabies, is a type of extreme scabies that harbors hundreds to thousands of mites and mite eggs in the skin crusts, causing severe symptoms of the skin.
Those afflicted with crusted scabies most often show widespread, dark, dense, cracking crusts.
Due to the food provided by the crusts themselves, mites living in the separated crusts can live up to a week without having human contact.
The most common site of adult and older infestation includes:
- in between the fingers
- around fingernails
- inner parts of the wrists
- inner elbow
- soles of the feet
- the breasts, particularly the areas around the nipples
- male genitalia
- shoulder blades
Infants and young children are infested in other areas of the body including:
- palms of the hands
- soles of the feet
Children may sometimes present with a widespread infestation that covers a majority of the body. Kids infested with scabies tend to show irritability signs, and problems in sleeping and eating.
Scabies is highly contagious, and anyone who has been diagnosed with the disease or who has had close contact with the patient will most likely be recommended to undergo scabies medication, even if they have no symptoms at all. It includes every person the patient has had an intimate contact with recently.
Scabies is usually treated with topical drugs such as permithrin cream, crotamiton cream, or lindane lotion 5 percent. A 25 per cent lotion of benzyl benzoate or 10 per cent ointment of sulfur may be used in some situations. Most of the topical preparations are applied in the morning and washed off at night.
Ivermectin, an oral drug, may be approved for those immunocompromised, those with crusted scabies or those who have not responded to topical therapy.
Ivermectin should not be used during pregnancy or breastfeeding, nor should it be used by children weighing under 33 pounds.
Other medications such as antihistamines, anti-itching lotions such as Pramoxine lotion, antibiotics, and steroid creams may be used to give symptom relief.
Treatment with recommended drugs usually quickly kills the mites. Initially the scratching and rash can get worse.
Skin healing should be seen after 4 weeks of treatment though. Some people require more than one treatment course to get rid of the mites altogether.
Tests and diagnosis
Scabies can be mistaken for dermatitis or eczema sometimes because these skin conditions often cause scratching and bumps on the skin. Anyone who is confused about the cause of a skin condition should consult their doctor as OTC treatments are not capable of eradicating scabies.
A doctor can diagnose scabies by examining the skin or looking under a microscope at scrapings of the skin.
Scabies is a sarcoptic scabiei mite infestation also known as the human itch mite.
The female mite lays its eggs in the tunnel it has formed, after burrowing under the skin. When hatched, the larvae migrate to the skin surface and spread by near physical contact throughout the body or to another host.
Human beings are not the only species which are affected by mites. It can also kill dogs and cats. Although humans that experience a mild, temporary skin reaction to contact with non-human animal mites, a full-blown human infection with animal mites is uncommon, however, each species hosts a different species of mites.
Scabies is highly contagious and transmitted by direct contact with the skin or through the use of a towel, bedding or furniture infested with the mites. As such, some of the people most likely to get infested with mites will include:
- children attending day care or school
- parents of young children
- sexually active young adults and people with multiple sexual partners
- residents of extended care facilities
- older adults
- people who are immunocompromised, including those with HIV/AIDS, transplant recipients, and others on immunosuppressant medications
Scabies home remedies often aren’t recommended.
Most infestations can cure without having to be treated. Nevertheless, it is mainly the preventive measures listed below that people with scabies can take without a doctor’s visit.
Herbal treatments, such as tea tree and neem oils, have not been consistently shown to cure scabies. And seeing a doctor and asking for a prescription is recommended.
Take the following steps to prevent re-infestation and spread;
- Wash or dry-clean all clothes, towels, linens, etc. When washing, use hot soapy water and dry on high heat. Place items that cannot be washed in a sealed plastic bag for one to several weeks to starve the mites.
- Vacuum the entire home on the day treatment is initiated, including carpets, rugs, upholstery, etc., and discard the bag or thoroughly clean the vacuum’s canister.
If you have questions about contracting scabies that you may have or may be at risk for, talk to a doctor.
Causes, symptoms, treatment of psoriasis in the ears
Psoriasis is a skin condition caused by an autoimmune disease. In some parts of the body, such as the ears, a thick layer of skin cells can form.
It usually affects the elbows, knees, legs, back, and scalp, although it can also affect more sensitive body parts.
Psoriasis is the most common autoimmune condition in the United States, and it comes in a variety of degrees of severity.
This article discusses the causes of psoriasis in the ears as well as treatment alternatives.
What is psoriasis?
Psoriasis is caused by an overactive immune system, which causes the fast development of extra skin cells. Experts aren’t sure whatcauses causing it.
It takes roughly 28 days for healthy skin cells to form. The body eliminates old skin cells during this time to make place for new ones.
In people with psoriasis, the body produces new skin cells every 3 to 4 days, leaving little time for old cells to slough.
This results in the accumulation of old and new cells on the affected areas, resulting in thick, red or silvery scales. These scales are often itchy, crack, and bleed, and they can be uncomfortable.
Researchers are still trying to figure out why psoriasis arises in certain parts of the body, including why some people get it in their ears while others don’t. They do know, however, that it cannot be passed from person to person.
According to a report published in the journal American Family Physician, psoriasis is not contagious. Scratching or touching does not cause psoriasis or transfer it to other parts of the body.
Psoriasis around the ears
People with psoriasis in their ears are extremely uncommon. However, if this occurs, an individual’s emotional and physical well-being may be jeopardised.
Psoriasis can cause the skin rough and scaly. Self-consciousness may be felt by people who have symptoms on their face and ears.
Because the skin on the face is frequently more delicate than that on the elbows, knees, and scalp, some treatments may be excessively harsh for this area. As a result, ear psoriasis might be more difficult to cure.
A blockage can occur if scales and wax build up inside the ear. Itching, pain, and hearing loss may cause from this obstruction.
Scales should be kept out of the ear canal to avoid hearing loss and discomfort.
Psoriasis might worsen over time for certain people. This can happen when something sparks a flare, but it’s often unknown why some people’s psoriasis spreads or worsens. New parts of the body, such as the ears, can be affected at any time.
There is no link between psoriasis in the ears and cleanliness, contact, or other things.
Anyone with psoriasis in their ears should see a doctor to find out which psoriasis treatments are safe to use in their ears.
Although there is no cure for psoriasis, it is generally managed with treatments.
People who have psoriasis in their ears may need constant medical attention to keep flares under control and avoid problems like hearing loss.
Some psoriasis drugs should not be used in the ears. Certain topical lotions and ointments, for example, may irritate the fragile eardrum. People should inquire about drugs that are safe for the ear canal with their doctor.
Among the treatment options available are:
- Eardrops containing liquid steroids.
- In addition, liquid steroids may be used in conjunction with another psoriasis treatment, such as a vitamin D cream.
- Shampoos with antifungal properties to help clean the ear and kill fungus.
- Medications that help the immune system work more efficiently.
- A few drops of heated olive oil to moisturise and remove wax inside the ears and keep them clean
If psoriasis in the ear causes discomfort or interferes with hearing, a specialist can safely and effectively remove the scales and wax.
It is critical not to attempt to remove the scales by inserting things into the ears.
Pushing the debris deeper into the ear can cause in a blockage, eardrum damage, or skin injury.
A doctor may give a systemic drug if the symptoms are mild to severe. Biologics, a relatively new class of medications, can treat the underlying causes of psoriasis.
The causes of psoriasis differ from individual to person. Certain factors can briefly aggravate psoriasis before it returns to normal for some people.
Others see their scales and other symptoms get worse over time.
In any case, psoriasis people should strive to avoid triggers wherever feasible. Those who have psoriasis in their ears may notice that a flare affects their hearing, which can be extremely aggravating and frustrating.
The following are some of the most common psoriasis triggers:
- Stress: While it may not always be feasible to avoid the causes of stress, being able to manage it can help prevent flare-ups. Relaxation, exercise, deep breathing, and meditation may all be beneficial.
- Medications: Certain medications, such as those for high blood pressure, heart disease, arthritis, mental health disorders, and malaria, might aggravate psoriasis. People with psoriasis should work with their doctors to discover treatments that do not exacerbate their condition.
- Cuts, scrapes, sunburn, and other skin injuries: Any type of skin trauma might cause in a new case of psoriasis in the affected area.
- Certain illnesses: When an infection strikes, the immune system goes into overdrive. This can also cause psoriasis flare-ups. Strep throat, ear infections, tonsillitis, and even regular colds can all cause flare-ups.
Avoiding triggers, whether on the ears, face, or other parts of the body, is an important component of controlling this condition.
Hearing loss and psoriasis
Even if psoriasis does not damage the skin in and around the ears, a person may nevertheless experience hearing loss.
People with psoriasis are more prone to acquire abrupt deafness, according to a study published in the American Journal of Clinical Dermatology.
This type of hearing loss might happen in a matter of minutes or over the course of a few days. People over the age of 50 are more likely to be affected by it.
The cause of sudden deafness in psoriasis is unknown, however it could be linked to the immune system harming part of the inner ear. Within 2–3 weeks, almost half of those who have abrupt deafness regain some or all of their hearing.
Doctors may advise that people with psoriasis and psoriatic arthritis have regular hearing tests to ensure that any abnormalities are detected and treated early.
Living with psoriasis in the ears
Many people suffer from psoriasis, which can be emotionally and physically draining, but with the help of a doctor, they can generally manage the condition.
Finding an effective treatment, whether the flares occur in the ears or elsewhere, is critical to reducing symptoms and flares.
Hearing tests and ear examinations should be done on a regular basis for people who have psoriasis in their ears so that any difficulties can be addressed as soon as feasible.
Because everyone with psoriasis reacts to drugs differently, finding the proper treatment may take some time. Some people’s psoriasis medicine stops working over time, necessitating the use of a different treatment.
People with psoriasis should be able to live full, active lives once they find a suitable treatment.
Psoriasis is a painful, long-term skin condition that can affect the inside and outside of the ear.
It is more difficult to treat than psoriasis elsewhere on the body when it does this. Hearing loss can occur as a result of the condition, both temporary and permanent. Although a complete treatment is not yet attainable, people can control their symptoms with condition and live a normal life.
To avoid serious flare-ups, get regular hearing tests and consultations.
Causes, symptoms, and treatments of nasal polyps
Nasal polyps are fleshy swellings that grow in the lining of the nose and the paranasal sinuses, which are air-filled cavities that connect the nasal cavity to the rest of the body. They aren’t malignant tumours.
Polyps come in a variety of sizes, colors, and shapes, such as teardrops. They eventually resemble grapes on a stem as they mature.
Polyps can appear in one or both nostrils at the same time, and they can grow alone or in groups.
Large polyps or clusters can obstruct the patient’s ability to breathe and cause their sense of smell. They have the potential to obstruct the sinuses and cause issues such as recurring infections.
Nasal polyps afflict 4-40% of the general population, and males appear to be 2-4 times more likely than females to develop them. People that develop them are usually in their twenties or thirties.
Nasal polyps are caused by a variety of causes that are unknown. Although non-allergic asthma is associated to a large percentage of cases, no respiratory or allergic trigger is detected in some cases.
Colonic and uterine polyps, which are found in the digestive tract and uterus, respectively, have no relation to nasal polyps.
Although the specific mechanism of polyp creation is uncertain, most studies agree that they are caused by swelling (inflammation) in the nose or sinuses and are not a disease.
Inflammation, according to some experts, causes fluid to accumulate in the interstitial space (the space between mucous-forming cells) of the nose and sinuses. Gravity eventually pushes these heavy cells down, becoming polyps. A bacterial or viral infection, an allergy, or an immunological response to a fungus are all possible triggers, according to scientists.
Nasal polyps most commonly arise around the sinus openings (in the nasal passage), however they can form elsewhere in the nasal passages or sinuses.
After asking about symptoms and seeing the patient’s nose, a doctor should be able to make a diagnosis. With the help of a lit tool, polyps are frequently visible.
The following tests may be ordered by the doctor:
- Nasal endoscopy – a narrow tube with a small camera (or magnifying lens) is inserted into the patient’s nose.
- CT scan – this enables the doctor to locate nasal polyps and other abnormalities linked to chronic inflammation. The doctor will also be able to identify any other obstructions.
- Skin prick allergy test – if the doctor thinks that allergies may be contributing to polyp development, he or she may do an allergy test.
- Cystic fibrosis – if the patient is a young child, the doctor may order a cystic fibrosis test.
Nasal polyps are commonly treated with the following methods:
The doctor may prescribe a steroid nasal spray or drops to reduce inflammation and shrink the polyps. Patients with one or more small polyps are more likely to receive this treatment. The following are examples of possible side effects:
- sore throat
2) Tablets containing steroids
In cases of larger polyps or more severe inflammation, steroid tablets may be administered, either alone or in combination with a nasal spray. Although steroid tablets are successful at shrinking polyps, they carry the risk of more serious side effects, such as weight gain, and should only be used for a few weeks at a time.
3) Additional drugs
Other medications may be used to treat disorders that exacerbate the inflammation. Antihistamines for allergies, antibiotics for bacterial infections, and antifungal medicines for fungus allergies are just a few examples.
Surgery is only utilised if the polyps are exceedingly large or if the patient’s other therapies have failed.
The most common method for removing polyps is surgery. A local or general anaesthetic is administered to the patient. In the patient’s nose and sinuses, a long, thin tube containing a video camera is introduced.
Micro-telescopes and surgical equipment are then used to cut away the polyps. To free up the nasal canal, the surgeon may remove small pieces of bone from the nose.
To help prevent recurrence, the patient will most likely be prescribed a corticosteroid nasal spray after surgery. To aid post-surgical healing, some doctors prescribe using a saline (saltwater) rinse.
If the symptoms of a nasal polyp appear to be related to an allergic reaction, avoiding the allergen that causes the reaction would most likely assist.
Although tea tree oil and other therapies have been suggested, there appears to be little evidence to back them up.
A steam bath might help relieve congestion symptoms.
Only a high therapeutic dose of vitamin D can help lessen symptoms. It is unknown how this works, how it should be supplied, or how effective it might be.
A big polyp, or cluster of polyps, can sometimes obstruct the flow of air and the drainage of fluids from the sinuses or nasal cavity, resulting in the following complications:
- Chronic or frequent sinus infections.
- Obstructive sleep apnea.
- The structure of the face may be altered, leading to double vision. Sometimes, the eyes may be set wider apart than normal (more common in patients with cystic fibrosis).
- Humidity. Consider using a humidifier if your home’s air is dry.
- Hygiene. Handwashing frequently and thoroughly lowers the risk of bacterial or viral infection, resulting in fewer incidences of sinus and nasal tract inflammation.
- Irritants. Some people may be able to lower their risk of developing polyps by avoiding irritants such as allergies, chemicals, and airborne pollution (which cause inflammation).
- Asthma and allergy management. Patients who follow their doctor’s asthma and/or allergy treatment guidelines are less likely to develop nasal polyps.
- Nasal lavage or nasal rinse. Using a nasal lavage or saline spray to rinse the nasal passages can assist increase mucus flow and remove irritants and allergens.
Cold sores: What to know
Cold sores are little blister-like lesions that appear on the lips, chin, and cheeks, as well as in the nostrils. They are less common on the gums and the roof of the mouth.
Before they burst and crust over, cold sores usually cause pain, a burning sensation, or itching. They’re also known as fever blisters.
The herpes simplex virus type 1 is the most prevalent cause of cold sores (HSV-1). These sores can also be caused by an infection with a different strain of the herpes simplex virus, known as herpes simplex virus type 2. (HSV-2).
HSV-1 is carried by 48.1 percent of all 14–49-year-olds in the United States, making them more prone to cold sores.
Although there is no method to cure or prevent cold sores, there are steps that can be taken to lessen the frequency and duration of outbreaks.
HSV-1 and HSV-2, the viral strains that cause cold sores, are highly contagious and spread rapidly during close contact, such as sexual contact.
Following the virus’s entry into the body, a person may experience the following symptoms:
- sores around the genital area, in some cases
- sores in or around their mouth or in their nostrils
- flu-like symptoms
If transmission occurs during oral sex, oral herpes blisters, often known as cold sores, can develop around the genitals.
Without therapy, a cold sore outbreak usually lasts 1–2 weeks before the virus is suppressed by the body’s immune system.
The virus does not leave the body, and while it is usually dormant, it can reactivate to cause cold sores on occasion.
The majority of people with oral herpes are unaware of their infection until they develop cold sores or other symptoms. Because the virus remains dormant, some people only experience one outbreak with no recurrence.
Others may experience recurrent outbreaks that last for years.
Some people with oral herpes have no symptoms, while others develop them after their initial infection.
Despite this, at least 25% of people with oral herpes have recurrent outbreaks. Cold sores occur in the same places over and over again in this example.
The following are some of the first signs of an HSV-1 infection that may develop 2–20 days after introduction to the virus:
- swollen lymph nodes
- lesions on the tongue, mouth, chin, cheeks, or in the nostrils
- mouth or tongue pain
- lip swelling
- a high body temperature
- difficulty swallowing
- a sore throat
Gingivostomatitis, an infection of the mouth and gums, may also be present. This lasts 1–2 weeks and does not happen again.
With the initial oral herpes infection, adults may develop pharyngotonsillitis, an infection of the throat and tonsils.
Symptoms of cold sores at various stages
When a cold sore recurs, it goes through various stages.
- The sores break and produce fluid.
- A yellow crust forms on the sores.
- The crust comes off, revealing pink skin that heals in 3–4 days.
- A tingling, itching, or burning sensation around the mouth often indicates the start of an outbreak.
- Painful, fluid-filled sores appear, usually around the mouth.
Most cold sores heal in 1–2 weeks without treatment and do not leave a scar.
Recurrent outbreaks can be managed at home by recognising the people and taking medication.
Consult a doctor if you have any of the following symptoms:
- The signs and symptoms are severe.
- Within ten days, a cold sore does not begin to heal.
Gums swell up.
- The person’s immune system is compromised.
- Other signs and symptoms are alarming.
A doctor can typically diagnose the problem based on the symptoms and a visual inspection, but in some situations — such as if the patient has a weaker immune system — a blood test or a sample of the sore’s fluid may be ordered.
HIV, drugs after an organ transplant, certain types of cancer, and various cancer treatments are all factors that might decrease the immune system.
Without therapy, most cold sore breakouts go away in 1–2 weeks.
Some over-the-counter and prescription treatments, on the other hand, can shorten the duration of an outbreak and alleviate any discomfort or pain, though they do not remove the virus from the body.
Treatments should be used as soon as the first signs of an outbreak show in most cases.
Creams with antiviral properties
Antiviral lotions sold over the counter can help to decrease the duration of an epidemic. Acyclovir or penciclovir is found in most creams, including Zovirax and Soothelip.
For 5 days, the cream should be applied to the affected area every 2–3 hours.
Antiviral medicines taken orally
The following are some examples of antiviral drugs that can be taken by mouth:
- valacyclovir (Valtrex)
- acyclovir (Zovirax)
- famciclovir (Famvir)
If a person has a weaker immune system or has frequent breakouts, a doctor may prescribe one of these drugs.
It is taken once or twice a day.
These drugs can help to decrease the duration of an outbreak and prevent it from happening again.
Analgesics like benzocaine or lidocaine are used in over-the-counter solutions. They do not hasten the healing process, although they can help to alleviate pain.
The following are some cold sore pain relief medications:
People should use a Q-tip to dab these ointments, lotions, or gels onto the sores, and they should not share these goods.
If a person uses their finger to apply the drug, they should wash their hands before and after.
Alternative drugs include ibuprofen (Advil) and acetaminophen (Tylenol).
At home remedies
Some people find relief from cold sore symptoms by using the following home care techniques:
- using petroleum jelly to keep the skin moist, preventing cracking
- dabbing the area with diluted geranium, lavender, or tea tree oil
- applying cold, soaked tea bags to the area every hour
There is no scientific proof that these therapies are effective or safe.
Oral herpes can cause difficulties in some people, especially those with compromised immune systems.
Complications that may arise include:
- If the sores make it difficult to drink, you may be dehydrated.
- Herpetic whitlow is a painful infection caused by a wound on the skin that causes blisters on the fingers.
- Herpetic keratoconjunctivitis is a secondary infection that can cause eye swelling and irritation, as well as sores on the eyelids and vision loss if left untreated.
- If the infection spreads, encephalitis (brain swelling) may ensue.
Encephalitis is a life-threatening condition.
When you have sores, attempt to:
- Kissing and other skin-to-skin contact with the affected area should be avoided.
- During oral sex, use a dental dam or a condom.
- Personal things, such as towels and lip balm, should not be shared.
- Use proper handwashing practises.
- Avoid touching regions including the eyes, mouth, nose, and genitals where sores can form.
- If it’s necessary to touch the sores, wash your hands with soap and warm water before and after.
Oral herpes can cause painful and inconvenient cold sores.
Many people have no problems and may treat outbreaks at home with over-the-counter or prescription medications.
If you experience cold sores or any other oral herpes symptoms, you should see a doctor very away if you have a weakened immune system.
Recognizing early signs of an outbreak and acting quickly to treat it can assist. Cold sores usually resolve after 1–2 weeks without treatment.
