The aim of this stud y was to compare the epidermal thinning properties of four corticosteroid ointments applied under occlusion, using histology and histometry. The results were surnmerized as follows: 1.The stratum corneurn was dramatically thinned, appearing as a wispy layer of horny cells as apposed to the norrnal basket-weave configuration. this effect was prominent at sites treated with clobestasol propionate, fluocinonide, and fluocinolone acetonide. 2. With the histometry, visible epidermal thickness wa.s markedly reduced. This effect w is prominent in the following ascending order: fluocinolone acetonide, fluocienonide, clobestasol-17-propionate. Hydrocortisone was the least atrophogenic. 3. Clohestasol-17-propionate and fluocinonide caused significant flattening of dermo-epidermal junction, Fluocinolone acetonide and hydrocortisone caused less pronounced cbanges. 4. Marked capillary dilation af papilly dermis is caused by clobestasol-17-propionate, fluocinonide and fluocinolone acetonide.

Behcet's disease (BD) is systemic vasculitis that can manifest severely debilitating. Despite the understanding mechanisms of overall BD, there are remains many questions in various critical manifestations and treatments. The ocular manifestation is characterized by a prototype of chronic relapsing and persistent uveitis. The main treatment is topical corticosteroid, and topical nonsteroidal anti-inflammatory drugs in mild uveitis. The recurrent and severe uveitis could be treated with ocular corticosteroid injections, and systemic corticosteroid for inducing long-lasting suppression of the inflammation. Systemic corticosteroids should rapidly be tapered within weeks for avoiding side effects. Recent advances have led to the development of sustained-release corticosteroid devices using different corticosteroids. We present a case of 67-year-old woman who received a fluocinolone acetonide implant for recurrent Behcet's uveitis. She was successfully treated with implant and the uveitis became quiescent within a month.

PURPOSE: Retisert(TM) (fluocinolone acetonide implant) has recently been approved for clinical use in patients with noninfectious posterior uveitis. We report a patient with intractable chronic Behcet's panuveitis who underwent Retisert(TM) implantation and showed a favorable outcome. METHODS: A 30-year-old male affected with intractable Behcet's uveitis of both eyes for over one year which did not respond to oral steroids and immunosuppressants; subcutaneous interferon injection caused undesirable side effects such as impotency and pyrexia. Initial visual acuities were 20/1000 in the right eye and 20/100 in the left eye, and both eyes showed severe panuveitis with posterior subcapsular cataract, especially in the right eye. The subtenon triamcinolone injection was performed in the right eye, which was only effective to anterior uveitis, and Retisert(TM) was implanted in the right eye after the cataract operation. Two months later the visual acuity increased to 20/25, and the inflammation was totally controlled. There were no ocular or systemic adverse events. CONCLUSIONS: Retiserttrade mark is a fast, effective, and safe treatment for chronic, non.infectious posterior uveitis.

Pretibial myxedema is a condition in which there is loeal thickening of the skin by a mucin-like deposit; it is nearly always asosciated with ophthalmopathy and thyrotoxicosis, not infrequently becomes more pronounced after treatrnent of thyrotoxicosis. The precise cause of pretibial myxedema is not known, but it appears that IgG LATS represents an autoantibody against a thyroid antigen, retroorbital tiesue and tbe skin, so, pretibial myxedema is presumed to be the result of a local antigen-antibody tissue reaction. A 57-year-old man had the history of diabetes since 1964 and Graves disease since May 1980, he was treated with metimazole for 1 month, with improving thyrotoxicosis but developed the pretibial myxedema. The histologic findings showed considerable amount of mucin, especially hyaluronic acid with toluidin blue stain at PH 3.0. The lesions were improved by local application of 0.01 x fluocinolone acetonide ointment with occlusive dressing technique.

BACKGROUND: Glucocorticoids are effective anti-inflammatory drugs widely used in dermatology and for the treatment of blood cancer patients. Unfortunately, chronic treatment with glucocorticoids results in serious metabolic and atrophogenic adverse effects including skin atrophy. Glucocorticoids act via the glucocorticoid receptor (GR), a transcription factor that causes either gene transactivation (TA) or transrepression (TR). Compound A (CpdA), a novel non-steroidal GR ligand, does not promote GR dimerization and TA, retains anti-inflammatory potential but induces fewer metabolic side effects compared to classical glucocorticoids when used systemically. As topical effects of CpdA have not been well studied, this work goal was to compare the anti-inflammatory and side effects of topical CpdA and glucocorticoids and to assess their effect on GR TA and TR in keratinocytes. METHODS: We used murine immortalized keratinocytes and F1 C57BlxDBA mice. Effect of glucocorticoid fluocinolone acetonide (FA) and CpdA on gene expression in keratinocytes in vitro and in vivo was evaluated by reverse transcription-PCR. The anti-inflammatory effects were assessed in the model of tumor promoter 12-O-tertradecanoyl-acetate (TPA)-induced dermatitis and in croton oil-induced ear edema test. Skin atrophy was assessed by analysis of epidermal thickness, keratinocyte proliferation, subcutaneous adipose hypoplasia, and dermal changes after chronic treatment with FA and CpdA. RESULTS: In mouse keratinocytes in vitro and in vivo, CpdA did not activate GR-dependent genes but mimicked closely the inhibitory effect of glucocorticoid FA on the expression of inflammatory cytokines and matrix metalloproteinases. When applied topically, CpdA inhibited TPA-induced skin inflammation and hyperplasia. Unlike glucocorticoids, CpdA itself did not induce skin atrophy which correlated with lack of induction of atrophogene regulated in development and DNA damage response 1 (REDD1) causatively involved in skin and muscle steroid-induced atrophy. CONCLUSIONS: Overall, our results suggest that CpdA and its derivatives represent novel promising class of anti-inflammatory compounds with reduced topical side effects.

Dermatologic treatment was greatly advanced when topical corticasteroids were introduced for the management of many inflammatory and pruritic dermatoses. Their use reduced or diminished mnst of the undiserable side effects which accompanied the systemic administration of these compounds. The good effects of topical application of hydrocortisone had been demonstration in the treatment of variaus dermatoses eg., atopic dermatitis, seborrheic dermatitis, contact dermatitis etc. The halogenated derivatives followed and led to the trend to most of analogs now in use. Especially, fluocinolone acetonide cream greatly enhanced its therapeutic effectiveness in psoriasis, chronic discoid lupus erythematosus, pustular bacterid, granuloma and neurodermatitis circumscripta. But many side effects of topical corticosteroids such as steroid acne. Stria were developed and also fluorinated topical corticosteroids resulted in telangiectasia, purpura, atrophy in skin. Weber reported that strong topical corticosteroids eg.. Betamethasone valerate and fluocinolone acetonide were resulted in rosacealikc dermatitis and it was steadily increased. These adverse side effcts of topical corticosteroids, especially steroid acne, were indisputable argument in dermatologic field, for the view that this topical corticosterodis is used for cosmetics and treatment of acne vulgaris in our country. Since the strong corticosteroid tnpical preparation, the peculiar form acne, so called steroid acne, was steadily increased in our clinic. Behrman and goodman reported that acneform eruption induced by hormone was not associated with oiliness and there were but few comedone. Sullivan and Zeligman reported that the the acneform eruption due to adrenal corticaa 1 hormone was uniform in size, small papule and few pustule, usualIy erythematous base. There were also differential histologic feature. The most important difference is the normal apperance of sebaceous glands in acneform eruption due to corticosteroids contrast with hyperplasia in acne vulgaris. Abscess formation was more frequent and more extensive in acne vulgaris. Sutton Jr and Van Scott & MacCardle described that histologically, the major component in lesion of steroid acne was excessive keratinization of follicle. Castor and Baker demonstrated that topical application of corticosteroids resulted in decrease of sebaceous gIands, decrease of mitosis and increased cornification in epidermis. The present study investigated clinical case of the steroid acne, which are induced by topical application and systemic administration of corticosteroids and experimentally induced the steroid acne with the topical application of corticosteroid. And also clinical cases and experimentally induced steroid acne were compared with acne vulgaris. Material and method Subjects are 13 Patients of steroid acne induced by strong topical corticosteroid eg., fluocinolone acetonide, fluocortolone, dexamethaone, betamethasone valerate and 4 patients of steroid acne induced by systemic administration of corticosteroid eg., prednisolone and also 10 patients of acne vulgaris. Biopsy was performed from 13 patients of topical steroid acne, 3 patients of steroid acne induced by systemic administration of steroid and one patient of acne vulgaris. In order to induce steroid acne, experimentally, strong topical corticosteroid such as beta methasone valerate, fluocinolone acetonide and fluocortolone were applied on back. Comment and conclusion In Clinical feature, the steroid acne by topical application and systemic administration of corticosteroid and experimentally induced steroid acne had unique clinicall features, that showed absence of comedone and uniform sized follicular papule on deep seated erythematous scaly base. The topical steroid acne was distributed the region where were applied. But the eruption of the steroid acne induced by systemic administration of corticosteroids was distributed to face, neck, and scalp. Above findings are quite different form acne vulgaris. Histopathologically, the steroid acne induced by topical application and systemic administration of corticosterojds showed hypoplasia of sebaceous glands and excessive follicular keratinization. Occlusion of pilosebaceous opening by keratotic plug in severe case by long term application showed atrophy of epidermis and sparsity of sebaceous glands with hypokeratosis and parakeratosis. In experimentally induced steroid acne, it was definitely specific features which were absolutely identcall with above cinical steroid acne.

Lidex' cream (Fluocinonide 0.05% in FAPG base) is a new fluorina,ted topical corticosteroid, and its clinical effect was assessed by applying topically three to four times daily to the lesions of 50 patients with a variety of inflamrnatory skin condi- tions. The results revealed excellent effect in 16 patients, moderate effect in 23 patients, slight improvement in 9 patients, and no effect in 2 patients. No unfavorable side effects were noted except blanching. The findings suggest that fluocinonide is an excelIent addition to the topical corticosteroid agents that are available for clinical use at the present time.
