Karp has spent many years developing medical adhesives, and he constantly looks to nature for inspiration.
Their quills are commonly used as jewellery by Native Americans, and they’re easily available. By shoving both shaved and unshaved barbs into pig skin, Cho showed that the barbs halve the penetration force needed to impale the meat. Once the team had sussed out the quills’ secrets, they duplicated them by creating artificial versions—barbs and all—from a plastic polymer. They could also be used for any device that stabs into flesh, from needles, to tissue tunnellers used in bypass operations, to the meshes used to repair hernias. Of course, you would then have to get those devices out again, and barbed porcupine quills would make that more difficult.
Not Exactly Rocket ScienceDive into the awe-inspiring, beautiful and quirky world of science news with award-winning writer Ed Yong. However, if your child has developed a rash and seems unwell, or if you're worried, you should see your GP to find out the cause and for any necessary treatment.
Eczema is a long-term condition that causes the skin to become itchy, red, dry and cracked. Impetigo is a highly contagious bacterial infection of the surface layers of the skin that causes sores and blisters. If you think your child has impetigo, see your GP for a prescription of antibiotic cream, which should clear the infection within seven to 10 days. A heat rash (prickly heat) may flare up if your child starts to sweat, for example because they are dressed in too many clothes or the environment is hot and humid. Keratosis pilaris is a common and harmless condition where the skin becomes rough and bumpy, as if covered in permanent goose pimples. It commonly affects young children aged one to five years, who tend to catch it after close physical contact with another infected child. Children tend to catch it after close physical contact with another infected adult or child – for example, during play fighting or hugging. Hives (also known as urticaria) is a raised, red, itchy rash that appears on the skin.
Most children won't need treatment as slapped cheek syndrome is usually a mild condition that passes in a few days. Psoriasis is a skin condition that causes red, flaky, crusty patches of skin covered with silvery scales. There is no cure for psoriasis, but a range of treatments can improve symptoms and the appearance of the affected skin patches.
Cellulitis is a bacterial infection of the deeper layers of the skin and the underlying tissue. It causes a red-brown spotty rash, which tends to start behind the ears and spread to the head, neck, legs and rest of the body. Most childhood rashes are not measles, but you should see your GP if you notice the above signs.

Hand injury is caused by fall on outstretched arm, direct impact to hand during work or auto accident.
Injury often is secondary to wear and tear of the tendon following forceful use of tendon several times a day and week. Baseball and basketball players handle the ball and use the muscles as well as tendon to throw the ball which eventually may sometimes result in tendon injury. Manual workers use heavy tools and vibrating tools, which often causes inflammation of the tendons of the hand. Penetrating Wound- Penetrating wound of the hand causes infection of the soft tissue which includes tendon. Spread of Local Infection- Soft tissue infection of skin and subcutaneous tissue often spreads into deeper tissue of hands resulting in tendonitis of the palm and fingers. Spread of Abscess- Abscess of wrist or fingers often spreads into palm and tendon of the fingers.
Degenerative disease of hand like osteoarthritis is associated with tendon degeneration and inflammation resulting in hand tendonitis. Arterial thrombosis or embolism of hand causes severe ischemia (lack of oxygen) resulting in ischemic tendonitis and atrophy of the tendon. Ischemia also causes lack of nutrition to soft tissue like tendon and results in inflammation of tendons of the hand.
Pain With Activities-Pain becomes severe with the activities of the hand and restricts the hand activities.
MRI is also performed like X-ray to rule out fracture, dislocation and inflammatory bone diseases. Ultrasound study is performed to diagnose abscess or hematoma (blood clot) within soft tissue of hand and finger. Different images are produced by different tissue like fluid (abscess), air and solid (bone) structure with different densities. Ice pack keeps the temperature of tendon and surrounding tissue at lower temperature, which helps to reduce pain and swelling. Tendon sheath infection is treated with antibiotics.1 Tendonitis associated with tendon sheath infection is often difficult to treat.
Physical therapy is advised to prevent muscle atrophy of forearm and hand muscles if tendonitis lasts for prolonged period.
Physical therapy is prescribed following the treatment of tendon inflammation and pain is less severe. Finger arthritis is very commonly observed disease that becomes a part of aging in majority of individuals. One can experience finger joint inflammation, swelling along with severe pain during finger arthritis. Excellent healing properties of cinnamon and honey helps in improving stiffed muscles of the body.

Together antimicrobial properties of cinnamon and antiseptic qualities of honey offers relief from arthritis pain.
All plant foods, especially celery seeds are packed with 25 anti inflammatory compounds and potassium that play a significant role in reducing finger arthritis. Warm a small portion of eucalyptus oil and then apply it as a thin layer over the finger joint having pain. Garlic is enriched with allicin, a compound that aids in suppressing reproduction and growth of microorganisms that usually aggravate the finger arthritis.
Eat garlic in raw or cooked form or heat the garlic cloves in mustard oil and apply over the swollen fingers, massaging it gently. Additionally, one may mix water with turmeric powder and drink one glass of it daily to get rid of finger arthritis.
Hot peppers are also an excellent solution for providing relief from finger arthritis pain.
Potato is enriched with anti inflammatory and anti oxidant properties that are very effective in relieving finger arthritis pain. Compound oleocanthal, present in olive oil helps in preventing the synthesis of pro inflammatory compounds COX 1 and COX 2 enzymes, thereby inhibiting inflammation of joints. Prepare a mixture of warm lavender oil and olive oil and massage with gentle strokes on regular basis, to get a rapid relief from finger arthritis. In addition to above natural solutions, one can just soak the fingers and hands in Epsom salt water for half an hour on daily basis, to improve pain and muscle cramps symptoms of finger arthritis. As our cool, wet New Jersey spring gives way to the warm days of summer, menacing mosquitoes are on the hunt!
You also can use an oral antihistamine such as Benadryl® to help relieve itching, especially if you have multiple bites. Your mosquito bite might be infected if the area gets redder, swelling increases, and the irritation spreads to a larger area. In this post you will discover all the facts, causes, symptoms and (DVT) Deep Vein Thrombosis treatment in the light of homeopathy. In this disease patient’s blood becomes thick and there develop blood clots in one or both of legs, therefore this disease is given the name of venous thromboembolism. Legs arteries get swelled and skin become sensitive, sometimes even a minute touch cannot bearable. Mostly this disease is found in non –O blood type of people but found in other blood groups also. The bad effects of the hormonal medicines, heparin drugs or chemotherapy can also gave birth to DVT disorder. Today’s spicy diet, fast foods, fizzy drinks and chemically preserved packed foods or juices becoming the major cause of DVT. Obesity and lazy living without any exercises can also give birth to venous thromboembolism prophylaxis. In homeopathic repertory mention these remedies, Arnica, Bothrops Lanceolatus, hamamelis virginiana, Lachesis, etc for this disease but it is very important that observe patient instead of disease and suggest most likely remedy according to the symptoms. Besides this the second most worthy remedy for DVT that come under my observation is Bellis Perennis. Avoid completely from more salt in taking in daily foods, processed foods, spices, red chilies, junk foods, vinegar, cold drinks and sour fruits for example oranges and citron.
If the patient gets relief by bending one leg (it could be affected or non affected leg) then Stannum Metallicum will be the final remedy.
Use Crataegus and Cactus in mother tincture if the patient has high blood pressure complaints.
If you discover a heave use of vinegar and sour foods in patient’s history then Aceticum Acidum will work fine. If the patient feel irritation in legs with cold outside and heat sensation inside then the medicine is Secale Cornutum and Agaricus Muscarius will be use for the vise versa. If the patient is also suffering in Vitamin K deficiency then the bio chemical salt Calcarea Fluorica 6X will work great. Beside the above stated remedies, Bothrops, Hamamelis, Collon Sonia, Sulphuric Acid, Natrum Mur, Pulsatilla and Sulfur are also the useful remedies and use can use any according to the symptoms.
A 6 months old baby girl, suffering from atopic eczema on the whole body since 2 months of age. Before we explore homeopathic remedies and treatment for various food allergies, let me define the allergy state. The dog’s face looked like a pincushion, with some 500 spines protruding from her face, paws and body. While it’s a myth that the quills can be shot out, they can certainly be rammed into the face of a would-be predator.
Woo Kyung Cho from Harvard Medical School and Massachusetts Institute of Technology has found that the barbs also make it easier for the quills to impale flesh in the first place. The barbed quills also slide in with less force than a hypodermic needle of the same width, or than the quill of an African porcupine, which doesn’t have any barbs (see end of post). He suspects that the barbs are acting like the serrated edges of a knife, concentrating forces at small points in the surrounding tissue.
So Karp’s team is now developing quills with degradable barbs, which could stick for a specified amount of time before being easily removed. If you continue without changing your settings, we'll assume that you are happy to receive all cookies on the NHS Direct Wales website. The most common form is atopic eczema, which mainly affects children but can continue into adulthood. The rash can appear almost anywhere on the body, with the scalp, feet and groin being common areas. It causes a non-itchy rash on the palms of the hands and soles of the feet, and can sometimes cause mouth ulcers and a general feeling of being unwell.
However, most adults are resistant to the virus, meaning they are unlikely to develop the condition if they come into contact with it. They leave small red blotches and silver lines on the skin, which may be found on the palms of the hands or soles of the feet. It happens when a trigger (see below) causes a protein called histamine to be released in the skin.

Repeated use of tendon resulting in frequent stretching causes inflammation of the tendon with microscopic tear and laceration of the tendon. Spread of abscess causes infection and inflammation of the tendon resulting in tendonitis of the hand. Pain becomes severe in later phase during inflammation and becomes chronic and lasts longer. Finger arthritis causes uneasiness and discomfort, making it extremely difficult to perform daily challenges. There are many medications available to improve the condition and many natural remedies to restore fingers to their original strength and flexibility. Use half a teaspoon of cinnamon powder and 1 teaspoon of honey on daily basis, to get rid of finger arthritis. Potassium deficiency has been known to ignite the arthritic discomfort and therefore, by consuming celery and other plant foods, good potassium supply is achieved by the body that aids in reducing finger arthritis symptoms. A warm compress enhances blood circulation, promotes relaxation of joints and muscles, and decreases joint stiffness. For best recovery, warm compress must be performed simultaneously with light finger exercises, to improve stiffness of fingers to a large extent. Continual massaging on regular basis will provide quick relief from finger arthritis pain and inflammation. Then mix these together to prepare a thick paste, apply it over the swollen fingers and keep it for half an hour.
Instead of water, turmeric can be added to warm milk and honey solution to attain the same anti inflammatory and anti septic benefits of turmeric.
Capsaicin present in hot peppers is also used in topical pain relieving drugs used commonly for arthritis pain. Cut a medium sized potato, without peeling off the skin and put the slices dipped in cold water overnight.
Hence, usage of olive oil in cooking overcomes the arthritis associated inflammation in fingers and other joints. Your symptoms can appear immediately or within a day or even 2 days after you’ve been bitten. Applying hydrocortisone cream (a corticosteroid) or Benadryl® cream (an antihistamine) several times can help minimize itching and lessen the urge to scratch! There becomes hindrance in the supply of blood and the patient becomes a victim of painful torment. In my personal experience Stannum Metallicum and Bellis Perennis are giving miraculous results for this disease.
During or after pregnancy, if someone becomes victim of DVT you can give Bellis Perennis mother tincture or 3X with full confidence and your patient will recover to normal in a miraculous way. Each one is tipped with microscopic backwards-facing barbs, which supposedly make it harder to pull the quills out once they’re stuck in. More recently, he started thinking about micro-needles—a recent invention that uses patches of tiny needles to painlessly penetrate the skin and, say, deliver vaccines. When Cho created replica quills with barbs that couldn’t bend, they took less effort to remove.
If a quill-inspired needle could be jabbed in more easily, surgeons might be able to place them more accurately. He wonders if African predators, like lions and leopards, are more aggressive than North American ones.
Microstructured barbs on the North American porcupine quill enable easy tissue penetration and difficult removal.
Tendonitis of the palm and finger associated with infection may not respond to anti-inflammatory medication and must be treated with antibiotics. Inflammation of the tendon may aggravate with continuous use of hand and tendon activities. Use a towel soaked in hot water over swollen fingers for several times in the day to get relieved from swelling. The eucalyptus instantly seeps in the finger joint with help of warm compress, improving joint flexibility and motility. Capsaicin works by obstruction the chemical involved in transmission of pain signals to the brain. Moreover, olive oil can be easily massaged over fingers and hands to reduce discomfort and inflammation of fingers. A few days back I went to see a patient whose left leg was becoming double due to swelling and she cannot walk even a single step.
These patches aren’t inherently sticky, but if they were, they could provide an interesting and more stable alternative to mere tape.  And when it comes to sticky spines, what better animal to study than the porcupine? Each quill has hundreds of barbs and Cho removed them all with folded sandpaper, taking care not to reduce the quill’s own diameter.
I recommended Arnica and Bothrops in the light of repertory to dissolve blood clots in the vein but the patient got only a minor relieve. Alternatively, African porcupines are larger than North American ones, and have longer quills—maybe, that makes a difference. Usually allopath doctors suggest low molecular weight heparin (anticoagulant) medicines for the patients and patient gets only temporary relief from it. When I keenly observe the patient, I notices she was sit by bending her effected leg, even though she was unable to walk or move. Sometimes the blood of patient become too thin with the use of those medicines and there starts bleeding from nose, mouth or anywhere from the body and it becomes more chronic situation. It is the pet symptom of Stannum, therefore, I gave single dose of Stannum 200 to her and the next day the swelling of the patient leg almost finished and she get busy in her household activities once again.
