Examples of "photodermatitis"
The symptoms are equivalent to
, but vary in severity.
The leaves have a bitter and unpalatable taste. Despite the lemon-like smell, the plant is acrid when eaten. All parts of the plant may cause mild stomach upset if eaten, and contact with the foliage may cause
Ingestion of pigments capable of producing singlet oxygen with activation by light can produce severe photosensitivity of skin (see phototoxicity, photosensitivity in humans,
, phytophotodermatitis). This is especially a concern in herbivorous animals (see Photosensitivity in animals).
The oils contained in the oil glands that are found throughout the above ground portions of the plant may cause irritation to the skin and in some cases are said to cause
Porphyria cutanea tarda has a prevalence estimated at approximately 1 in 10,000. An estimated 80% of porphyria cutanea tarda cases are sporadic. The exact frequency is not clear because many people with the condition never experience symptoms and those that do are often misdiagnosed with anything ranging from idiopathic
and seasonal allergies to hives.
Delayed type 4 allergic hypersensitivity reactions including aculopapular exanthema, erythematous rash, urticarial eruption, erythema multiforme,
, eczema and Stevens–Johnson syndrome can occasionally occur as a result of tetrazepam exposure. These hypersensitivity reactions to tetrazepam share no cross-reactivity with other benzodiazepines.
Ramira ("Alexandra Jiménez") works in Laura's house ("Silvia Abril") as maid and nanny of her kids: Simeón and Ofendia ("Óscar Lara" & "Laia Alda"). Unfortunately, Ramira kills the child because he saw the sun despite suffering from
. The woman tries to hide and lies to the mother about the death of her son.
Examples of common drugs causing drug eruptions are antibiotics and other antimicrobial drugs, sulfa drugs, nonsteroidal anti-inflammatory drugs (NSAIDs), biopharmaceuticals, chemotherapy agents, anticonvulsants, and psychotropic drugs. Common examples include
due to local NSAIDs (such as piroxicam) or due to antibiotics (such as minocycline), and the rash following ampicillin in cases of mononucleosis.
may result in swelling, difficulty breathing, a burning sensation, a red itchy rash sometimes resembling small blisters, and peeling of the skin. Nausea may also occur. There may also be blotches where the itching may persist for long periods of time. In these areas an unsightly orange to brown tint may form, usually near or on the face.
, sometimes referred to as sun poisoning or photoallergy, is a form of allergic contact dermatitis in which the allergen must be activated by light to sensitize the allergic response, and to cause a rash or other systemic effects on subsequent exposure. The second and subsequent exposures produce photoallergic skin conditions which are often eczematous. In rare cases the victims die.
There is a rapid onset of clinical signs over the period of 2–7 days, beginning with anorexia, lethargy, and hyperbilirubinemia (icterus and discolored urine). Signs of hepatic encephalopathy (ataxia, blindness, aggression, and coma) and fever can also occur. Other signs include
, hemorrhagic diathesis, dependent edema, and colic. The reason for colic is unknown, but is thought to be due to rapid decrease in the size of the liver, and the increased risk of gastric impaction. Rarely, weight loss can occur.
Medical organizations such as the American Cancer Society recommend the use of sunscreen because it aids in the prevention of squamous cell carcinomas. Many sunscreens do not block UVA radiation, which does not primarily cause sunburn but can increase the rate of melanoma and
. The use of broad-spectrum (UVA/UVB) sunscreens can address this concern. Diligent use of sunscreen can also slow or temporarily prevent the development of wrinkles and sagging skin.
The underlying mechanism can be immunological (such as in drug allergies) or non-immunological (for example, in
or as a side effect of anticoagulants). A fixed drug eruption is the term for a drug eruption that occurs in the same skin area every time the person is exposed to the drug. Eruptions can occur frequently with a certain drug (for example, with phenytoin), or be very rare (for example, Sweet's syndrome following the administration of colony-stimulating factors).
Phytophotodermatitis, also known as "lime disease" (not to be confused with "Lyme disease"), "Berloque dermatitis", or "Margarita
" is a chemical reaction which makes skin hypersensitive to ultraviolet light. It is frequently mistaken for hereditary conditions such as atopic dermatitis or chemical burns, but it is caused by contact with the photosensitizing compounds found naturally in some plants and vegetables like parsnips, citrus fruits and more. Symptoms include burning, itching and large blisters that slowly accumulate over time.
Toxic epidermal necrolysis has occurred from the use of tetrazepam including at least one reported death. Stevens–Johnson syndrome and erythema multiforme has been reported from use of tetrazepam. Cross-reactivity with other benzodiazepines does not typically occur in such patients. Exanthema and eczema may occur. The lack of cross-reactivity with other benzodiazepines is believed to be due to the molecular structure of tetrazepam.
and phototoxicity have also been reported. Occupational contact allergy can also develop from regularly handling tetrazepam. Airborne contact dermatitis can also occur as an allergy which can develop from occupational exposure.
Medical organizations such as the American Cancer Society recommend the use of sunscreen because it aids in the prevention of squamous cell carcinomas. Many sunscreens do not block UVA radiation, which does not cause sunburn but can increase the rate of melanoma and
, so people using sunscreens may be exposed to high UVA levels without realizing it. The use of broad-spectrum (UVA/UVB) sunscreens can address this concern. Diligent use of sunscreen can also slow or temporarily prevent the development of wrinkles and sagging skin.
The skin response resembles an exaggerated sunburn. The involved chemical may enter into the skin by topical administration or it may reach the skin via systemic circulation following ingestion or parenteral administration. The chemical needs to be "photoactive", which means that when it absorbs light, the absorbed energy produces molecular changes that cause toxicity. Many synthetic compounds, including drug substances like tetracyclines or fluoroquinolones, are known to cause these effects. Surface contact with some such chemicals causes
; many plants cause phytophotodermatitis. Light-induced toxicity is a common phenomenon in humans; however, it also occurs in other animals..
Antibiotics are screened for any negative effects before their approval for clinical use, and are usually considered safe and well tolerated. However, some antibiotics have been associated with a wide extent of adverse side effects ranging from mild to very severe depending on the type of antibiotic used, the microbes targeted, and the individual patient. Side effects may reflect the pharmacological or toxicological properties of the antibiotic or may involve hypersensitivity or allergic reactions. Adverse effects range from fever and nausea to major allergic reactions, including
and anaphylaxis. Safety profiles of newer drugs are often not as well established as for those that have a long history of use.
Hydroa vacciniforme (HV) is a very rare, chronic
-type skin condition with usual onset in childhood. It was first described in 1862 by Bazin. It is sometimes called "Bazin's hydroa vacciniforme". A study published in Scotland in 2000 reviewed the cases of 17 patients and estimated a prevalence of 0.34 cases per 100,000 population. In this study they reported an average age of onset of 7.9 years. Frequently the rash first appeared in the spring or summer months and involved sun-exposed skin. The rash starts as a vesicular eruption, later becoming umbilicated, and resulted in vacciniform scarring. It is most frequently found on the nose, cheeks, ears, dorsum of the hand, and arms (places that are most exposed to light).
The series followed the adventures of Nick Knight, a Toronto cop working the graveyard shift with his partner Donald Schanke. Unbeknownst to most of his colleagues, Nick is actually Nicholas, an 800-year-old vampire (his human name was a pun based on his status as a literal knight in medieval France). Remorseful over centuries spent as a vampiric cold-hearted killer, Nicholas works as a cop and often ends up using his special abilities to bring criminals to justice. Nicholas explains his need to work on the night shift by claiming to have a skin disorder,
, which requires him to stay out of sunlight. Refusing to feed from humans, he survives by drinking bottled animal blood, something that most vampires find repulsive. The only one who knows his true nature is his friend Natalie Lambert, a city medical examiner who doesn't like for Nicholas to use his special powers as she believes it increases his need for blood.
