2,829 Possible Causes for Photosensitivity

  • Sunburn

    Cutaneous photosensitivity reactions require absorption of photon energy by molecules in the skin.[accessmedicine.mhmedical.com] This reaction is distinct from true photosensitivity. Photosensitivity is listed in the drug brochure for methotrexate.[ncbi.nlm.nih.gov] , Photosensitive reaction , Photosensitivity reaction (NOS) , Photosensitivity reaction NOS , Reaction photosensitivity (NOS) , Photosensitivity toxic reaction , Photosensitized[fpnotebook.com]

  • Drug Eruptions

    Besides piroxicam (a well-known photosensitizer) and carbamazepine, isoniazid and triflusal were identified as the causes of the reactions.[ncbi.nlm.nih.gov] […] autoimmune blistering diseases, Stevens-Johnson syndrome, toxic epidermal necrolysis, drug-induced acne, acute generalized exanthematous pustulosis, lichenoid drug eruptions and photosensitivity[ncbi.nlm.nih.gov] […] patients; other reactions being urticaria and angioedema,morbilliform rash in 37, pruritus in 25, Stevens Johnson Syndrome (SJS) in 6, purpura in 6, exfoliative dermatitis in 5,photosensitivity[ncbi.nlm.nih.gov]

  • Duodenal Ulcer

    Abstract Typical symptoms of duodenal ulcers include epigastric pain, nausea, vomiting, chest pain and shortness of breath. Here we present the case of a 39-year-old man who had a sudden onset of chest and epigastric pain following the use of recreational amphetamines. There were ST changes in the inferior leads[…][ncbi.nlm.nih.gov]

  • Porphyria

    The Diagnosis of Photosensitivity. Arch Dermatol. 2000;136(9):1152–1157. doi:10.1001/archderm.136.9.1152 Download citation file: 2019 New![doi.org] Abstract Many photosensitive patients are seen for consultation when they have no lesions, so a detailed history is important.[ncbi.nlm.nih.gov] Erythropoietic protoporphyria is characterized by childhood onset of acute cutaneous photosensitivity to direct sunlight.[web.archive.org]

  • Systemic Lupus Erythematosus

    The prevalence of serositis was also higher and photosensitivity less.[doi.org] This photosensitivity can be accompanied by worsening of inflammation throughout the body, called a "flare" of the disease.[web.archive.org] We reported two cases of SLE with psoriasis vulgaris with clinical manifestations as recurrent erythroderma with photosensitivity.[ncbi.nlm.nih.gov]

  • Early Infantile Epileptic Encephalopathy Type 6

    SIGNIFICANCE: Photosensitivity is an important feature in DS and seems to be a marker of the severity of the disorder.[ncbi.nlm.nih.gov] By five years of age, photosensitive myoclonic absence seizures had become his dominant seizure type, occurring up to 20 times per day.[ncbi.nlm.nih.gov] Photosensitivity is reported in more than 40% of patients.[ncbi.nlm.nih.gov]

  • Acute Hepatic Porphyria

    Differential diagnoses for variagate porphyria and hereditary coproporphyria also include photosensitivity.[orpha.net] The majority of patients exhibit acute attacks, while 20% can also present with skin-related symptoms, such as photosensitivity and blistering skin lesions.[symptoma.com] Photosensitivity may be controlled by avoiding exposure to light. Removal of the spleen is useful in some cases of the erythropoietic type of porphyria.[medical-dictionary.thefreedictionary.com]

  • Acute Intermittent Porphyria

    Photosensitivity may be controlled by avoiding exposure to light. Removal of the spleen is useful in some cases of the erythropoietic type of porphyria.[medical-dictionary.thefreedictionary.com] The presence of fluorescent red cells (fluorocytes) in AIP is probably under-recognized since AIP is a hepatic porphyria and not associated with photosensitivity.[ncbi.nlm.nih.gov] […] uncommon; residual defects during latent periods include polyneuropathy in both conditions, ataxia and retinitis pigmentosa with night blindness in Refsum disease, [7] and photosensitive[emedicine.medscape.com]

  • Erythropoietic Porphyria

    […] activity of uroporphyrinogen III synthase and the accumulation of nonphysiologic isomer I porphyrin metabolites, resulting in ineffective erythropoiesis and devastating skin photosensitivity[ncbi.nlm.nih.gov] Pseudoporphyria, a drug induced bullous disorder with photosensitivity, is closely similar to CEP.[doi.org] […] extremely rare disease with mutation in the gene that codes for uroporphyrinogen III synthase leading to accumulation of porphyrin in different tissues and marked cutaneous photosensitivity[ncbi.nlm.nih.gov]

  • Erythropoietic Protoporphyria

    Erythropoietic protoporphyria (EPP) is a rare inherited disease characterized by dermal photosensitivity due to the accumulation of photosensitizer protoporphyrin IX.[ncbi.nlm.nih.gov] Following sunlight exposure, the resulting photosensitivity is manifested first as pain, later as erythema, edema and dermal lesions.[ncbi.nlm.nih.gov] KEYWORDS: cosmeceuticals; erythropoietic protoporphyria; photosensitivity disorder; protoporphyrin; sunlight[ncbi.nlm.nih.gov]
