Briefly, let’s go back in history when Betsey Johnson became known as fashion designer during the late 1960s. According to Elizabeth Hanson, Johnson became a well-known fashion designer after creating brands for the first. ![]() ![]() ![]() ![]() In 2. 01. 4, Toys R Us was forced to pull Breaking Bad figurines off the shelves after protests from outraged families - but this isn't the only time toys have been banned, discontinued or otherwise removed from sale for being too controversial. Here are nine other times toys weren't suitable for kids - or indeed, anyone. Matador Barbie. Barbie has had numerous jobs since her introduction in 1. Paleontologist, News Anchor, Paratrooper and Stewardess – but the job that got her in most trouble was probably her brief time as a Matador bullfighter. Released in 1. 99. Invented by art student Xavier Roberts in 1978, the Cabbage Patch Kids line was one of the biggest toy fads of the 1980s and remains one of the longest. Belk, Melanie Wallendorf, and John F. Matador Barbie was criticised for its implicit endorsement of the brutal Spanish sport, which sees bulls ritually slaughtered after an extended period of taunting and provocation. Celebrity fan Alicia Silverstone even sent Mattel's chairman Robert Eckert a letter urging him to discontinue the doll. The campaign worked, and the following year the toy was permanently discontinued. Snacktime Kid Cabbage Patch Doll. Invented by art student Xavier Roberts in 1. Cabbage Patch Kids line was one of the biggest toy fads of the 1. But not every release is a hit. In 1. 99. 6, Mattel released the Snacktime Kid – a Cabbage Patch Doll with a motorised jaw that allowed it to . Children initially loved the gimmick, but things went sour when it emerged that the doll wouldn't stop chewing until its mouth was empty. The indiscriminate and unrelenting mastication inevitably shunned plastic morsels in favour of mashing up tiny fingers and snagging long hair in its merciless mechanical jaws, tearing it from young scalps at the root. Unable to sate the Snacktime Kid's lust for human flesh, Mattel was forced to remove the toy from sale. Sky Dancers. Released by Galoob in 1. Sky Dancers were winged fairy dolls which would launch high into the air with the pull of a cord, at which point they'd extend their arms outwards to slow their descent and spin gracefully back to Earth. At least, that was the fantasy. The reality was that the super- fast spins and harsh plastic bodies proved a powerful and unpredictable combination. I've spoken before about the World's most tragic and magnificent love story playing out high in the sky above our heads. The Sun and the Moon, constantly chasing one. The Alexander Doll Co. Your best bet would be to try the Doll Doctors’ Association website to find a. I have only focused my collection on vintage mass market Cabbage Patch Kids from the early 80s, so I will only share. The original cabbage patch is worth millions. The cabbage patch kids were made in the year 1983. They were actually sold during 1985. They were credited with breaking teeth, lacerating faces, causing temporary blindness and at least one concussion. After over 1. 00 injuries were reported in six years, 9 million Sky Dancers were recalled in June 2. Play Along Toys in 2. Lawn Darts. Cast in solid metal and heavily weighted so as to stick convincingly into the ground, Lawn Darts allowed any child to experience all the fun of a dartboard with all the danger of chucking around what was essentially a deadly weapon. After it emerged that they were responsible for a reported 7,0. Lawn Darts were banned by the Consumer Product Safety Commission in the US in December 1. Unlike the original (safe) specification, Bindeez now metabolised into Gamma- Hydroxybutyric Acid when swallowed. Otherwise known as GHB, the substance is a powerful drug that can act as sedative, stimulant, anaesthetic and intoxicant. Bindeez were immediately banned when nine children ended up in hospital after swallowing them. Gilbert U- 2. 38 Atomic Energy Laboratory. These days if you tried to carry radioactive material anywhere near a toyshop, you'd be thrown into jail so fast you probably wouldn't even get a trial. But in the 1. 95. So it was that in 1. A. C. Gilbert released the U- 2. Atomic Energy Lab, each example of which contained four samples of Uranium Ore as well as genuine sources of alpha, beta and gamma particles. In 1. 95. 1 it was (perhaps not unreasonably) removed from sale when it was feared that children might swallow the radioactive sources. U- 2. 38 has been linked to cancers like Leukaemia and Lymphoma, as well as Gulf War Syndrome. Worst Christmas present ever. CSI Fingerprint Examination Kit. TV's most unrelenting franchise relented from the shelves pretty quickly when it emerged that a CSI- licensed Fingerprint Examination Kit was considerably more dangerous than the fake crimes it was being used to investigate. That's because a vial of fingerprint dust included in the box contained industrial- grade asbestos - up to 7% of the dust was made of the stuff. It might sound hilarious in the abstract, but it's hardly a laughing matter – just a single exposure to asbestos of this type can lead directly to lung cancer in later life. Unsurprisingly, the manufacturer of the toy went bankrupt. Carmageddon. The UK is pretty relaxed in its video game censorship compared to some countries, but even then the original 1. Carmageddon proved too much for the BBFC, which banned the automobile- based murder- 'em- up from sale, allegedly for basing its reward system purely on the number of innocent bystanders you could transform into mincemeat. The game was eventually rated for release after a change was made that turned the pedestrians into zombies with green blood, and 1. All Simpsons Toys. Surprised? You won't be when we reveal that in 2. The Simpsons was banned in Iran as part of an attempt to combat . This, just a few months after the same ban was applied to all Barbie toys in the country as well, leading the raids and arrests on shops selling the dolls. The Simpsons' ban cited the Springfield family’s self- centred and irreligious attitudes as the motivating factor. We can all relate to that.

Subacute cutaneous lupus erythematosus can present in an annular form on sunexposed surfaces or in a papulosquamous form. Erythema annulare centrifugum typically presents as annular patches with trailing scale inside erythematous borders. The term âannularâ stems from the Latin word âannulus,â meaning ringed.
Using a scalpel blade, the scales are scraped at the active border of the lesion, with particular care not to cause pain or bleeding. The specimen is transferred to a glass slide, and a coverslip is placed on top to protect the specimen. A drop of 1. 0 to 1. KOH, with or without dimethyl sulfoxide (DMSO; Rimso- 5. The specimen is then gently heated; specimens prepared with DMSO do not require heating. Overheating or boiling the specimen may cause the KOH to crystallize, which leads to artifacts. First, the specimen should be examined under low- power magnification. The KOH and the heat dissolve the keratinocyte cell membrane, leaving behind easily visualized septate hyphae, which are long and may be straight or wavy. These structures may also branch and generally have a uniform diameter. If repeated KOH preparations are negative in a patient with a clinically suspected dermatophyte infection, fungal cultures are recommended. The cultures may take two to four weeks for growth. TREATMENT OF TINEA CORPORIS The herald patch is generally a singular, ovoid macule located on the trunk and can range from 2 to 1. These lesions are generally bilaterally symmetric and may be located anywhere on the body, especially on the neck, trunk and proximal extremities. Because the lesions follow the skin cleavage lines, they have the characteristic appearance of a Christmas tree.
Subcutaneous granuloma annulare is characterized by large, skin- colored nodules that may be as deep as the lower dermis or subcutaneous fat.
Diagnosis is typically based on clinical appearance and correlation with pathology. Laboratory tests are generally of little benefit
The typical skin changes may wax and wane and may include infiltrated papules and plaques, subcutaneous nodules and infiltration of old scars.
Topical or intralesional corticosteroids may be beneficial for localized skin disease.
Urticaria may affect 1. Following the release of histamine and other mediators, increased vascular permeability results in massive edema of the superficial dermis.
This mechanism is associated with urticaria caused by pollens, foods, medications, fungi, molds, Hymenoptera venom and parasitic infections. Antibody- dependent, cell- mediated cytotoxicity (type II hypersensitivity) and antigen- antibody complexes (type III hypersensitivity) and activation of the complement system account for the urticaria occurring in persons with transfusion reactions and serum sickness, respectively. Physical urticaria includes pressure urticaria, which appears under sites of tight clothing, on the soles and wherever a heavy load is carried; cold urticaria, which usually occurs on the hands, ears, nose and the cooler fatty areas, such as lateral thighs in women; cholinergic urticaria, which is usually precipitated by fever, hot baths or exercise; solar urticaria; and dermograph urticaria. In most cases of urticaria, the specific etiology remains unclear. A lesion of urticaria usually lasts between 9. Urticarial vasculitis is not actually urticaria but a leukocytoclastic vasculitis that can mimic urticaria clinically, with the exception that the lesions may persist up to three to five days. In these patients, a skin biopsy for histopathologic confirmation of vasculitis is warranted.

University of Maryland Medical Center. Treatment Options. Prevention. Treat underlying diseases and avoid known triggers (certain medications, for example). It is also important to avoid the sun when taking certain medications. Treatment Plan. Your doctor will treat any underlying diseases, stop any drugs that may contribute to symptoms, and take steps to control your current symptoms. Mild cases may not require treatment. Bed rest and medication may be necessary for more severe cases. Drug Therapies. Antihistamines for itching. Antibiotics. If you have an infection, though research suggests many cases of erythema can be resolved without antibiotics. Antiviral medications such as acyclovir and valacyclovir, if you have a virus. Aspirin and nonsteroidal anti- inflammatory drugs (NSAIDs)Burrow's compresses, a solution used to soothe skin conditions, particularly blisters. Corticosteroids, applied to the skin (topically); corticosteroids may also be taken orally to reduce symptoms of erythema nodosum. Intravenous immunoglobulin, used experimentally for SJS and TENPhotomodulation therapy, use of a light- emitting diode to accelerate the resolution of erythema Complementary and Alternative Therapies. To treat erythema, you must treat the underlying cause. It is important to get a proper diagnosis from your doctor before using complementary and alternative therapies (CAM). Not all CAM therapies are appropriate for all people, and some may interact with conventional medicines or therapies. You should use CAM therapies only under the guidance of a physician. Some CAM therapies may be used to: Reduce inflammation. Boost the immune system. Prevent infections Nutrition. Antioxidants are molecules that scavenge free radicals (chemicals that can damage cells). Antioxidants also may protect skin against damage caused by ultraviolet (UV) sun rays. The following antioxidants have been shown to protect skin against damage in scientific studies: Beta- carotene and other carotenoids (up to 3. IU per day for beta- carotene): Beta- carotene is often used as a standard treatment for sun sensitivity, although studies have been mixed. In one trial, though, 2. E. Both groups improved significantly, but vitamin E did not appear to add any benefits. Scientists think the protective effect of beta- carotene comes from its antioxidant effect, so it's possible other antioxidants may also help protect skin from damage. Vitamin B6 (1. 00 mg per day for 3 months): Some case reports suggest that vitamin B6 can help reduce the reaction to sunlight. You should only take high doses of vitamin B6 under a doctor's supervision, because of the risk of side effects. Vitamin B6 can interfere with Amiodarone (Cordarone), Phenobarbital (Luminal), Phenytoin (Dilantin), and possibly Levodopa. Speak with your physician if you are taking any of these medications. Vitamin C (1 to 3 g per day, lower dose if diarrhea develops): Vitamin C is an antioxidant, so it may provide some protection against skin damage from sunlight. Vitamin C can negatively impact certain health conditions, and can interfere with some medications. Speak with your physician. Vitamin E: Vitamin E is also an antioxidant, and a few studies have shown that it can offer protection from sun damage to skin when taken with vitamin C (but not alone). However, other studies have not found the same results. Vitamin E may interact with certain medications, including but not limited to, blood- thinning medications, such as warfarin (Coumadin). It may also have negative effects on people with bleeding disorders, head and neck cancers, Retinitis Pigmentosa, and other conditions. Vitamin D: In animal studies, vitamin D helped protect against damage from UVB rays. It is not clear yet whether vitamin D supplements may protect humans in the same way. Vitamin D can interact with some medications, including but not limited to, Digoxin and Verapamil. It may also have a negative impact on some health conditions. Speak with your physician. Other Supplements. Melatonin: Applying melatonin topically (either alone or in combination with vitamin E) seems to offer some protection against sunburn in healthy people, but it is not known whether melatonin also lessens effects in people prone to erythema. Zinc: Zinc is necessary for healthy skin and was used in a study along with other prescription medications as a treatment for a severe form of erythema multiforme similar to TEN. In the study, 5 out of 8 people treated with zinc showed a benefit. Because high doses of zinc can be dangerous, many doctors suggest doses below 5. Talk to your doctor to determine which dose is right for you. Zinc can interact with certain antibiotics, Cisplatin, Amiloride, and Penicillamine (used for Wilson syndrome and Rheumatoid arthritis). Herbs. Flavonoids: Some of these plant- based antioxidants may protect skin from sun damage in healthy people. In one study, German researchers found that drinking high flavonol cocoa offered protection from the sun (the cocoa used was a special formulation that is not available commercially). In another study, pomegranate fruit extract helped protect skin cells in a test tube from UV light. It is not yet known whether taking the extract would provide any benefit. However, adding fruits and vegetables to your diet to eat more flavonoids may help. You can also take these flavonoids in dried extract form. Speak with your physician first, since certain flavonoids can interact with prescription medications: Catechin, quercetin, hesperidin, and rutin. Rose hips (Rosa canina) are also high in flavonoids and may be used as a tea. Drink 3 to 4 cups per day. Hesperidin methyl chalcone is a water- soluble form of quercetin that may act as an antihistamine. Green tea (Camellia sinensis) may also protect against erythema caused by UV light because it contains antioxidants. Herbs traditionally used topically to heal damaged skin, promote lymph circulation, and possibly treat the underlying cause of various skin conditions may be helpful. You should check with your doctor before using any of these remedies. Some examples include: Aloe vera: Used topically for skin inflammation. One study found that aloe vera displayed anti- inflammatory effects superior to 1% hydrocortisone gel. Burdock root (Arctium lappa): Used topically for skin inflammation and wound healing. Never apply to an open wound. Calendula (Calendula officinalis): Used topically for burns, wounds, and other skin conditions. Never apply to an open wound. Goldenseal (Hydrastis canadensis): Used for infections, including those causing skin lesions. Lemon balm (Melissa officinalis): Can be applied to HSV lesions as a cream or a wash. Sage extract: Applied topically to reduce inflammation. In one study, sage extract significantly reduced the ultraviolet induced erythema to a similar extent as hydrocortisone. Slippery elm (Ulmus fulva): Applied topically, in combination with goldenseal root. Never apply to an open wound. Yarrow (Achillea millefolium): Applied topically for skin inflammation and wound healing. Never apply to an open wound. Homeopathy. Although few studies have examined the effectiveness of specific homeopathic therapies, professional homeopaths may consider the following remedies for the treatment of erythema based on their knowledge and experience. Before prescribing a remedy, homeopaths take into account a person's constitutional type, includes your physical, emotional, and psychological makeup. An experienced homeopath assesses all of these factors when determining the most appropriate treatment for an individual. Apis mellifica: For skin rashes that feel hot and dry and are sensitive to touch; may be accompanied by sore throat. Symptoms are relieved by cool drinks and baths and worsened by heat and warm liquids. This remedy is most appropriate for individuals who often feel sad, disappointed, or even depressed. They tend to cry easily, but may also be irritable and envious by nature. They are also not thirsty but may crave milk. Calendula: For burns and skin lesions that are fairly superficial. This remedy is often used after the acute phase of the skin condition has subsided to aid in complete recovery. Rhus toxicodendron: Used for blisters and vesicles accompanied by intense itching that worsens at night and improves with the application of heat. This remedy is most appropriate for individuals who are generally restless and unable to get comfortable at night. Sulphur: For skin disorders that are accompanied by fever and intense itching. This remedy is most appropriate for individuals who are thirsty, irritable while sick, lazy, and messy under ordinary circumstances, and who describe a sensation of internal heat and burning. Symptoms tend to improve with open, cold air and worsen with warmth. Supporting Research. Beers MH, Porter RS, et al. The Merck Manual of Diagnosis and Therapy.
