Multiple issues orphan February 2009 unreferenced November 2008 unreferenced May 2009 Steroid atrophy is a side effect of the use of topical steroid s. It can be seen with other changes associated with chronic topical steroid use, including tinea incognito fungus of the skin , steroid induced telengiectasia, steroid induced acne or rosacea, and steroid induced skin fragility. Long term use of an oral or systemic steroid can also cause skin fragility, although not as evident as topical steroid under occlusion. Cause The prolonged used of a topical steroid, especially under occlusion on the face, or body fold. Steroid atrophy can occur on any body surfaces, but the groin, buttock crease, face, arm pits, breast folds, and body folds are most commonly affected. Strong topical steroid Class I, or fluorinated steroids can induce the condition very quickly, while a weaker steroid Class V and below can induce it slowly over time.

Unfortunately, if prolonged used of a strong topical steroid in a thin occluded skin area is suspected, the steroid induced changes might not totally be reversible. Prevention Judicious use of topical steroid. Strong topical steroid should be limitted to areas of unoccluded and thick skin such as the arms, and legs. Weaker topical steroid should be used on the face, groin, body folds, breast folds, and perineal area.

Steroid induced rosacea is an Iatrogenesis iatrogenic condition induced by the physician or patient from the use of either systemic steroid or topical steroids. It is nearly identical to steroid induced acne from the standpoint of etiology. ref http dermnetnz.org acne steroid rosacea.html ref Etiology Steroid induced rosacea can be caused by the prolonged used of a topical steroid on the face. Topical steroid comes in 7 different strengths Some countries use 4 categories . Class I is superpotent, and class VII is very weak. Usually, any categories of steroids over class VI can induce rosacea with prolonged use. The presentation is typically of inflammatory acne lesions consisting of pustules, papules, and cysts. The patient often admits to the daily use of a topical steroid, often being under the advisement of a physician. Examination of the pustules often revealed inflammatory cells, and in many cases, numerous motile demodex mites. Treatment Treatment often involve the gradual weaning off the topical steroid, and the use of a systemic antiinflammatory antibiotic. If the patient is using a strong topical steroid, he or she is weaned to a weaker class VI or VII steroid. Usually they are to use the substitute steroid daily, then only on weekends, then stop completely. The facial dermatitis and discomfort often worsen when they stop the offending steroid. The oral antibiotic will decrease the inflammatory nature of the lesions. The antibiotic of choice is usually a tetracycline antibiotic. Additionally, Tacrolimus combined with oral antibiotics has proven to speed up the recovery process. ref http www.rosacea.net steroid.html ref ref http dermnetnz.org acne steroid rosacea.html ... should be applied to the face.

Unreferenced date December 2009 Steroid diabetes also steroid induced diabetes is a medical term referring to prolonged hyperglycemia due to glucocorticoid therapy for another medical condition. It is usually, but not always, a transient condition. Medical Conditions The most common glucocorticoids which cause steroid diabetes are prednisone and dexamethasone given systemically in pharmacologic doses for days or weeks. Typical medical conditions in which steroid diabetes arises during high dose glucocorticoid treatment include severe asthma , organ transplant ation, cystic fibrosis , inflammatory bowel disease , and induction chemotherapy for leukemia or other cancer s. Insulin Glucocorticoids oppose insulin action and stimulate gluconeogenesis , especially in the liver , resulting in a net increase in hepatic glucose output. Most people can produce enough extra insulin to compensate for this effect and maintain normal glucose levels, but those who cannot develop steroid diabetes.

Steroid Maximus is an instrumental side project of J.G. Thirlwell . Thirlwell is best known for his main band, Foetus band Foetus . Steroid Maximus contains elements of jazz , big band , avant garde , soundtrack and exotica styles. History Following the recording of Foetus Interruptus Thaw album Thaw , J.G. Thirlwell felt that too many instrumental songs were making their way onto Foetus albums. Thirlwell s future work was split between two distinct entities songs with lead vocals were released under the Foetus moniker, and instrumental works were released as Steroid Maximus. The official debut of Steroid Maximus came in 1990 with the release of the single Volgarity on a flexi disc compilation. The following year saw the release of the Quilombo album Quilombo LP, Steroid Maximus first album written by Thirlwell with guest performances by Lucy Hamilton , Hahn Rowe , Michel Langevin Away , and Raymond Watts . Steroid Maximus second album, Gondwanaland album Gondwanaland , was released in 1992. In addition to further collaboration with Raymond Watts on 6 of the 14 tracks, Thirlwell wrote, recorded and produced the second effort with astonishing results. Gondwanaland also contained the Volgarity single and a cover version cover of Raymond Scott s Powerhouse song Powerhouse a favorite soundtrack of many classic Looney Tunes shorts which was originally released by Thirlwell under his Garage Monsters moniker. Recent After a decade long hiatus, Thirlwell revived his Steroid Maximus project in 2001 without Watts .

enzyme Name steroid delta isomerase EC number 5.3.3.1 CAS number 9031 36 1 IUBMB EC number 5 3 3 1 GO code 0004769 image width caption In enzymology , a steroid Delta isomerase EC number 5.3.3.1 is an enzyme that catalysis catalyzes the chemical reaction a 3 oxo Delta sub 5 sub steroid math rightleftharpoons math a 3 oxo Delta sub 4 sub steroid Hence, this enzyme has one substrate biochemistry substrate , 3 oxo Delta5 steroid , and one product chemistry product , 3 oxo Delta4 steroid . This enzyme belongs to the family of isomerase s, specifically those intramolecular oxidoreductase s transposing C C bonds. The systematic name of this enzyme class is 3 oxosteroid Delta5 Delta4 isomerase . Other names in common use include hydroxysteroid isomerase , steroid isomerase , Delta5 ketosteroid isomerase , Delta5 or Delta4 3 keto steroid isomerase , Delta5 steroid isomerase , 3 oxosteroid isomerase , Delta5 3 keto steroid isomerase , and Delta5 3 oxosteroid isomerase . This enzyme participates in c21 steroid hormone metabolism and androgen and estrogen metabolism . Structural studies As of late 2007, 25 tertiary structure structures have been solved for this class of enzymes, with Protein Data Bank PDB accession codes PDB link 1BUQ , PDB link 1C7H , PDB link 1CQS , PDB link 1DMM , PDB link 1DMN , PDB link 1DMQ , PDB link 1E97 , PDB link 1GS3 , PDB link 1ISK , PDB link 1K41 , PDB link 1OCV , PDB link 1OGX , PDB link 1OGZ , PDB link 1OH0 , PDB link 1OHO , PDB link 1OHP , PDB link 1OHS , PDB link 1OPY , PDB link 1VZZ , PDB link 1W00 , PDB link 1W01 , PDB link 1W02 , PDB link 1W6Y , PDB link 2PZV , and PDB link 8CHO .

enzyme Name steroid N acetylglucosaminyltransferase EC number 2.4.1.39 CAS number 9033 56 1 IUBMB EC number 2 4 1 39 GO code 0047261 image width caption In enzymology , a steroid N acetylglucosaminyltransferase EC number 2.4.1.39 is an enzyme that catalysis catalyzes the chemical reaction UDP N acetyl D glucosamine estradiol 17alpha 3 D glucuronoside math rightleftharpoons math UDP 17alpha N acetyl D glucosaminyl estradiol 3 D glucuronoside Thus, the two substrate biochemistry substrates of this enzyme are UDP N acetyl D glucosamine and estradiol 17alpha 3 D glucuronoside , whereas its two product chemistry products are uridine diphosphate UDP and 17alpha N acetyl D glucosaminyl estradiol 3 D glucuronoside . This enzyme belongs to the family of glycosyltransferase s, specifically the hexosyltransferases. The systematic name of this enzyme class is UDP N acetyl D glucosamine estradiol 17alpha 3 D glucuronoside 17alpha N acetylglucosaminyltransferase . Other names in common use include hydroxy steroid acetylglucosaminyltransferase , steroid acetylglucosaminyltransferase , uridine diphosphoacetylglucosamine steroid , and acetylglucosaminyltransferase .
