Are Crabs (Pubic Lice) Contagious?

Pubic lice, also known as ‘crabs’, is a condition which occurs when certain parasitic insects are present in the genitals. These insects cause red spots to form on the vagina which result in itching. Crabs are also known to affect other parts of the body such as eyebrows, eyelashes and beards. This disease is extremely contagious in nature; it can be passed on from one person to another via sexual intercourse, hugging and kissing. In some cases, this condition can also be passed on from the parent to the child.


If you are affected by crabs then you will have itching and pain in the genitals. The saliva of the insect can cause allergic reactions on the skin, resulting in the itch. The itching tends to worsen at night. Bluish or red spots may appear on the affected area. The lice are usually around 2 cm long and can’t be spotted easily.


Contrary to popular belief, pubic lice or carbs are not caused by poor hygiene. This disease spreads via bodily contact with an infected person and they feed on human blood to survive. Lice usually spread via sexual intercourse which may be anal, vaginal or oral.

Treatment for pubic lice

Treatments for pubic lice involve shampoos, lotions and insecticide creams. Some of the treatments for pubic lice need to be applied locally while others require full body treatment. Apart from following the treatment procedures, you need to take preventive measures to prevent infestation. Avoid sharing personal items such as toiletries, as lice can spread through it.

Allergy Testing By Skin Prick Method

Allergy Testing By Skin Prick Method

The skin prick test is considered to be the ‘gold standard’ for determining an allergen causing the reaction. The test is quick, easy, and the results are easily visible. This article contains a summary of how the skin prick test works, how preparations are done, and how it is performed.

How does it work?
The skin prick method for allergy test is based on inducing an allergic reaction in a very small area of the skin in a controlled manner. An isolated allergen is thus inserted by making a small prick in the skin. If an allergic response occurs, blood vessels in that area just under the skin dilate and fluid leaks out under the skin. This causes a small, red and itchy bump to form on the skin in about 15-20 minutes. The same reaction can result in a much more severe condition if it occurs systemically in response to that allergen. Hence, the skin prick test is used to pinpoint an allergen causing a response.

What preparations are done for the test?
In preparation for the test, taking antihistamines or oral corticosteroids is prohibited for a period of about 48 to 72 hours before the test is performed, including medications containing these. Application of topical lotions or ointments on the skin is also prohibited. Before testing, the healthcare practitioner shall collect a complete medical history of the patient, including previous occurrences of allergic reactions and the situations they happened in. This information is used to determine the allergens that need to be tested for.

How is it performed?
After making a study of the patient’s case history, the allergens that need to be tested are determined. The test is performed in the following steps:

  1. The area of the skin to be tested is cleaned with a swab of alcohol and small marks are placed on the skin to demarcate the different allergens used.
  2. A drop of the allergen in solution or suspension is put on the skin, a different allergen on each mark.
  3. The skin under each drop is lightly pricked with a sterilized needle. This causes a small amount of the allergens to go into the skin to induce the immune system.
  4. If a positive reaction occurs to one or more of the allergens, a small, red and itchy swelling develop on each of those particular marks in 15-20 minutes. Further tests may be performed in this case.

11 Causes Of Angioedema And Its Prevention!

Allergic reactions are the body’s way of responding to foreign substances. The body recognizes these substances (be it food, pollens, insect bites, etc.) as antigens and produces antibodies. These antibodies can cause various reactions depending on the severity of the allergen, be it skin rash, hives, or angioedema. In severe cases, there could be swelling of the tongue and the respiratory tract, leading to choking of the airways.

Literally, angioedema means swelling of the blood vessels. These are located in the underlying layers of the skin and their swelling can lead to formation of giant hives, which can be extremely itchy, reddish, and oval or circular in shape. The affected area I usually warm and painful to touch.


Angioedema is caused due to the following:

  1. Food allergies including eggs, peanuts, shellfish, milk, tree nuts, chocolates, etc.

  2. Insect bites or stings

  3. Pollen, latex, animal dander, poison ivy, and other common allergens

  4. Medications like aspirin, penicillin, ibuprofen, and some blood pressure medicines

  5. In response to blood transfusions

  6. Auto-immune disorders like lupus

  7. Conditions like leukemia and thyroid disorders

  8. Infections like hepatitis, cytomegalovirus infections, Epstein-Barr infections, etc.

  9. Weather conditions like extremes of cold, heat, or pressure

  10. Extreme emotional stress

  11. Genetic angioedema, passed on from parents to children, which could last forever

While hives usually develop without any warning, the following condition puts a person at risk of developing angioedema.

  1. Predisposition to allergic reactions (highly active immune system)

  2. Previous history of allergies

  3. Genetic history of allergies or angioedema

Most angioedema cases are limited to the skin and hives, but there could be severe cases leading to respiratory distress.


If it is the first instance of hives, the doctor would ask detailed questions about similar occurrence in the past. They would also check if there are similar hives on other parts of the body like the back, which you may have missed. If required, this examination is followed by allergy testing and blood testing. The allergy testing will help identify if you are allergic to some of the common things which cause allergy. The blood test will look for your eosinophil count, which is usually high in people prone to allergies. C1 esterase inhibitor test and complement particles also can be checked, if there is suspicion of genetic angioedema.


This would depend on the severity of symptoms

  1. In case of angioedema, admission in hospital may be needed.
  2. Tracheostomy may also become essential to save patients life.
  3. Vigorous therapy with intravenous medications like steroid, antihistamines and others may be needed.
  4. Under medical treatment, antihistamines like cetirizine and loratadine are prescribed. However, severe cases may require steroids like prednisolone.


Once you know what caused it, avoid exposure to these substances and further attacks can be prevented. In case you have a concern or query you can always consult an expert & get answers to your questions!

Autoimmune Diseases - How These 10 Diet Hacks Can Be Beneficial For You?

An autoimmune disease often develops when your immune system, which guards your body against any kind of illness, starts attacking your own body. It decides that your healthy cells are foreign and attacks the healthy cells. Depending upon the type of illness, an autoimmune disease can influence one or various types of body tissue. It can bring about unusual organ development and changes in organ functioning.

A good diet is essential and a basic requirement so that it does not trigger aggravation in the digestion systems and further weaken your intestines. The diet should be taken in small portions to avoid bloating in the stomach. One should eat in small portions after every two to three hours. Some of the dietary measures for an autoimmune disease are as follows-

  1. Stay away from gluten: In case you have an autoimmune disease, you generally require a lab test to know that you need to stay away from gluten. This protein, which is found in wheat, spelt, rye and grain, is connected to numerous immune system conditions.

  2. Locate your reactive foods and discontinue them: Even grains that do not contain gluten like corn and rice can cause reactions in the immune system in a few people. Atomic mimicry happens when your body confuses your own body tissue for the similar kind of proteins found in a few foods. See whether you are having any food that you might be allergic to.

  3. Include green tea and turmeric into your daily diet: They dampen the autoimmune reaction in many parts of the body especially the brain.

  4. Stay away from refined table salt: Table salt has been shown to irritate and aggravate some of the autoimmune conditions.

  5. Consume egg whites: They have anti-bacterial components and have the property to bind some of the nutrients. A few people will argue that they're fine when cooked. However, if you choose to just have the yolks, you can do so without any worry.

  6. Take a healthy meat diet: Some meats like chicken, fish, sheep and turkey are good for the health. Swordfish and lord mackerel are high in mercury. Select infection free chicken, turkey, and sheep.

  7. Consume low Glycemic Organic Fruits: Consume fruits including apples, apricots, avocados, berries, cherries, grapefruit, lemons, oranges, peaches, pears, plums for healthy glucose absorption.

  8. Coconut intake: Coconut margarine, coconut cream, coconut milk, coconut oil, unsweetened coconut pieces, unsweetened coconut yogurt are great for health.

  9. Herbs and Spices: Spices like basil, dark pepper, cilantro, coriander, cumin, garlic, ginger, lemongrass, mint, oregano, parsley, rosemary, sage, ocean salt and thyme should be used.

  10. Fermented food: Kimchi, cured ginger, aged cucumbers, coconut yogurt, kombucha, water kefir, and so forth need to be consumed for the vitamins and nutrients they contain.

Why Visit Your Dermatologist In Case Of Rashes?

Whether your complexion is fair or dark, almost everyone suffers from a rash at some point of time of the other. A rash can be described as a change in colour of texture of the skin. Most rashes are not life threatening. Skin rashes can be triggered by bacterial, vital or fungal infections and respond well to over the counter topical medication or oral antihistamines. May rashes are also triggered by a change in weather conditions and humidity or dry skin. However, there are some instances where a rash should not be ignored and a doctor should be consulted.

When a rash is accompanied by other symptoms
As a general rule of thumb, a rash that is accompanied by fever, muscle aches, crams etc should not be ignored. In such cases the rash is usually a symptom of a larger problem such as measles, scarlet fever and shingles or an allergic reaction.

  • Rashes that do not respond to medication: Rashes can take anywhere from a few days to a few weeks to completely heal but regular use of topical creams and oral antihistamines should how improvements in a day or two. Any rash that does not respond to topical ointments and continues to spread to other parts of your body must be shown to a doctor at once.
  • Widespread rashes: Most rashes are localized and restricted to a small area. Widespread rashes are usually a sign of allergies and need medical attention. Rashes that emerge suddenly should also be shown to a doctor as soon as possible.
  • Painful rashes: While itchiness may be commonly associated with many types of rashes, pain is a symptom of a bigger problem. Painful rashes should be immediately shown to a doctor.
  • Rashes that become infected: Rashes that itch may cause scratching that can lead to added infections. Hence, ideally, a rash should never be scratched. Swelling, yellow or green discharge, crusting, warmth in the area around the rash and red streaks radiating out from the rash are signs of infections.
  • A rash that begins to blisterMost rashes only cause bump on the surface of the skin. If these bumps turn into blisters or open sores, medical attention should be immediately sought. This is especially necessary in cases where the rash is around the eyes, mouth or genitals. A blistering rash may be due to an allergic reaction, reaction to medication or an internal trigger.

Allergies - Possible Signs That Indicate Them!

Allergies are a reaction of your immune system to any foreign matter, such as pet dander, pollen or bee venom, and not everyone is affected in the same way.

Antibodies are substances produced by your immune system to protect you from harmful invaders that can cause infections or make you ill.

The immune system produces antibodies when it comes into contact with allergens. Your immune system can recognise any allergen as threatening even if it’s not. As a result, your skin, airways, digestive system or sinus gets inflamed.

Allergies can vary greatly in severity from mild irritations to anaphylaxis (a likely life-threatening emergency). Allergies are mostly incurable; however, there are various treatments available to alleviate allergy symptoms.


Common triggers of allergy include:

  1. Airborne allergens, such as mould, dust mites, animal dander and pollen.

  2. Certain foods, especially milk, eggs, shellfish, fish, soy, wheat, tree nuts and peanuts.

  3. Insect bites, such as wasp stings or bee stings.

  4. Medications, specifically penicillin-based antibiotics or penicillin.

  5. Latex, or any allergen you touch, causes skin infections.



Symptoms of allergy depend on its type.


Treatments of allergy include:

  1. Avoiding Allergens: Your doctor can help you take necessary steps to recognise and avoid the allergens that trigger allergies. This is usually the most relevant step in the prevention of allergic reactions and reduction of symptoms.

  2. Medicines to Lower Symptoms: Eye drops, nasal sprays or oral medications are commonly prescribed to reduce reactions and alleviate symptoms.

  3. Immunotherapy: If the allergy is severe or other treatments fail to relieve symptoms, allergen immunotherapy is recommended. In this treatment, you get injected by a number of clarified allergen extracts over the years.

  4. Emergency Epinephrine: If your allergy is severe, your doctor will provide you with an emergency epinephrine shot that you can carry with you everywhere.

Angioedema - 11 Reasons Why It Can Happen!

The body’s reacts to anything suspicious by developing an allergic reaction. Some of the common substances inducing this reaction include certain food substances, pollen, insect bites and certain metals. This body recognises these suspicious substances as antigens and produces what is known as antibodies. These produce various allergic reactions in the body ranging from something as minor as a skin rash to something drastically fatal as respiratory distress and even death.


  1. Angioedema is one of the most severe forms of allergic reactions.
  2. Translated literally as swelling of the blood vessels, angioedema causes swelling of the blood vessels in the underlying layers and this can lead to the formation of giant hives.
  3. The hives or rashes are extremely itchy, reddish, and can vary in shape (oval or circular). The hives also are warm and painful when touched.
  4. Angioedema usually affects the skin but can have more severe effects like blocking the airway and leading to respiratory distress

Causes: Angioedema is usually caused by one of the following:

  1. Insect bites or stings
  2. People with allergies to foods like peanuts, eggs, milk, shellfish, chocolates, tree nuts, etc.
  3. Pollen, animal dander, latex, poison ivy, and other common allergens
  4. Medicines like penicillin, aspirin, ibuprofen, and some anti-hypertensives
  5. Autoimmune skin disorders like lupus
  6. Reaction to incompatible blood transfusions
  7. Weather conditions like extremes of cold, heat, or pressure
  8. Infections like hepatitis, cytomegalovirus infections, Epstein-Barr infections, etc.
  9. Conditions like leukaemia and thyroid disorders
  10. Extreme emotional stress
  11. Genetic angioedema, inherited from parents by children, which can last forever

Risk factors: Though hives usually develop without any warning signs, the following are some risk factors for developing angioedema.

  1. Previous history of allergies
  2. Predisposition to develop allergic reactions (overactive immune system)
  3. Genetic history of allergies, especially of angioedema


  1. In first-time patients, a detailed history with deep dive into similar instances in the past will be done
  2. A physical exam to check for missed hives (like the back) is then done
  3. Allergy testing may also be required to test if a person has a high predisposition to allergies
  4. Blood testing to check for eosinophils, which is usually high in patients with allergies, is done.
  5. Allergy testing to identify the trigger agent may be done if trigger is not known. This will help in preventing further attacks.
  6. If genetic angioedema is suspected, C1 esterase inhibitor test and complement particles are also checked.

Non-medical treatment including loose clothing, cool compresses, and copiously moisturizing to reduce dryness and itching. This is usually sufficient in majority of the cases.
Medical: Antihistamines like cetirizine and loratadine are the next line of treatment. Very severe cases may require steroids like prednisone. In case you have a concern or query you can always consult an expert & get answers to your questions!

Allergic Rhinitis - Top Signs And Symptoms You Must Always Know!

Allergic Rhinitis - Top Signs And Symptoms You Must Always Know!

Allergic rhinitis is the swelling and inflammation of the nasal cavity. It occurs in response to an allergic reaction initiated by the contact of nasal mucosa with allergens, which commonly are minute particles like pollen grains. The nasal cavity comprises of 3 meatuses and conchae, the superior, middle and inferior. Bones present around these meatuses and conchae are called as the turbinates. These bony structures are responsible for obstruction of any foreign particle entering the nasal cavity.

Production of mucous prevents entry of minute particles through the nose into the lungs. Due to certain factors like low immunity, these foreign particles gain an entry in the nose and cause irritation. The inflammatory reaction initiated by in the nasal passage by dust, pollen grains, bacteria, pathogens causes local swelling giving rise to the symptoms of allergic rhinitis. A specifically seasonal form of allergic rhinitis is known as Hay fever.

Ayurveda describes allergic rhinitis to be a result of accumulation of toxins and decreased immunity in an individual. These accumulated toxins are known to affect the 2 humors in the body, namely vata and kapha. Other contributing factors mentioned in Ayurvedic texts for allergic rhinitis are a prolonged period of digestive problems, inhalation of smoke or dust, weather changes, weak immune system and unhealthy lifestyle. People having furry pets at their homes also stand at a high risk for developing rhinitis. From an Ayurvedic perspective, certain cause of allergic rhinitis can further be described. Low digestion strength is termed as ‘Mandagni’ which means low fire. Increase of the kapha dosha is ‘Kaphavruddhi’. ‘Viruddha aahara’ is the consumption of improper combinations of food.

Signs and symptoms of allergic rhinitis are as follows-

Most common-

  1. Sneezing
  2. Blocked or stuffy nose
  3. Runny nose, post nasal drip
  4. Continuous irritation in the nostrilsItching of throat, eye, nose
  5. Cough
  6. Facial pain
  7. Fatigue and irritability
  8. Watery eyes, puffiness around the eyes

Diagnosis of allergic rhinitis can be made by evaluation of the physical symptoms. Also, confirmatory tests like an allergy test, skin test and blood tests can be done. Symptomatic treatment approach is followed.


The Ayurvedic approach for treatment of allergic rhinitis propagates maintaining a balance of humors of the body. Eradication of the accumulation of toxins is the primary aim of treatment. Firstly, dietary changes are advised. Changes in lifestyle habits in accordance to the seasonal changes are required to be made. If prone to allergy, certain precautions like covering the mouth when in contact to dust, refraining from petting furry animals, keeping homes dust free are advised.If an individual is suffering from a chronic form of allergic rhinitis, then a ‘Panchakarma’ is preferred, which relieves the Tridosha and eliminates accumulated toxins from the body. Nasal symptoms are treated by use of nasal oils. A light, minimally spicy and cooked in less oil is recommended. Lukewarm water and soups should be taken regularly. Relief from constipation is necessary.

Herbs that are useful for treating allergic rhinitis are as follows-

Haldi (Turmeric) helps to improve stamina and combat the allergic reaction. It also acts as an anti-oxidant. Purnarnava is an immunity modulator and anti-inflammatory medicine. It reduces the frequency of hypersensitivity reactions. Pepper prevents the accumulation of toxins and reduces sneezing and itching of nose.Practicing Yoga also helps in relieving symptoms. Kapalbhati, Anulomvilom Pranayam, Vrukshaasan, Bhujangasan and Shavaasan can be practiced regularly. In case you have a concern or query you can always consult an expert & get answers to your questions!
