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.

Erythroplasia of Queyrat is a precancerous lesion, usually located to glans penis or prepuce. It is characterized by a slowly developing, circumscribed, usually velvety and shiny patch. The etiology was unknown, but it is extremely rare in those circumcised in early infancy. It had been suggested that phimosis had some etiologic importance. The typical case of Erythroplasia of Queyrat is presented. A 46 year old man had 4 months history of dark-brownish pea sized maculopapular rashes on sulcus of glans penis and prepuce associated with mild itching, which was increased in number day by day. He had a phimosis. On examination, there are sharply defined, slightly elevated, pea sized dark-brownish maculopapular rashes over erythematous infiltrated base on sulcus of glans penis and prepuce, which have moist and velvety appearance. A biopsy was performed from sulcus of glans penis. Histopathologically, there was acanthosis, with in epidermis many cells are vacuolated and showed individual cell keratiinization. Epithelial cell showed marked atypia, variation in nuclear size and there was intercellular, intracellular edema. The lesion was treaterd with topical application of 5% 5-fluorouracil twice daily 2 weeks and thereafter for 4 weeks. 2 months after treatment, no erythroplastic lesion was found and 3 months after treatment, rebiopsy was perforrned which showed marked improvement histopathologically.

This clinical study of nine patients presented Disseminated Superficial Actinic Porokeratosis (DSAP) as a distinctive and recognizable entity characterized by multiple uniformly small, irregular marginated, keratotic plug with atrophic center developing during second or third decade of life on sun exposed area of skin. Six of nine patients had DSAP, which was inherited as autosomal dominant trait. The patient's father, two brothers and two sisters were known to have same skin lesions. Of nine patients, five were female and four were male. Eight patients were developed DSAP lesions during second decade of life and other one was third dcade of life. Three patients had pruritus. In alI patients, lesions were developed bilaterally over sun exposed area but was not always symmetrical. The number of lesion was multiple in all patients. The greatest number of lesions were found on distal part of extremities, neck, face, upper portion of anterior chest and back.

The case of a 30 year old man is described, in whom mycosis Fungoides was originating from nose and followed by tumor stage of Mycosis Fungoides on skin. In January 1970, the patient leveloped nasal tumor, when he was n at E.N.T. department of Severance Hospital. At that time a biopsy of nasal tumor demonstrated only a non-specific inflammatory cell infiltrated mass. He received radiation therapy (Co 60) with satisfadory suppression of mass and resulted in right nasal septal deviation. Jn December 1970, thumb sized painful non-tender, movable mass developed on right supraclaviular area. In August 1971, thumb sized painful, tender, movable mass appeared at right posterolateral aspect of neck, which was excied and removed at local clinic. But excised wound was not healed and the mass was enlarged. One month after above lesion, pea sized same mass developed. On physical examination, there were 4*5cm round, erythematous, painful, tender, granulomatous ulceration mass on right postero-lateral aspect of neck and also same mass on postero-inferior site of above lesion. Two times of biopsy was done and it interpreted as tumor stage of Mycosis Fungoids. Treatment included radiation therapy with Co 60 (200r/day, total 6,000r), prednisolone 40mg/day and antibiotics. There has been good response 1 month after radiation therapy and mass is diminished in size and would begin to heal.

Confusion of a patent ductus arteriosus (PDA) for the descending thoracic aorta is a fatal error occurring occasionally in infants or neonates. As a result, the left pulmonary artery (LPA) may be misconceived as the PDA, and ligated. This surgical mishap of other hospital leads to serious congestive heart failure and loss of left lung function due to the underdevelopment in the peripheral vascular and alveolar structures in neonates and premature infants. In this report, 3 cases of LPA ligation and subsequent treatment are presented.

BACKGROUND: Thromboxane A2 and endothelin-1 are the potent vasoconstrictors affecting pulmonary pathophysiology in response to whole body inflammatin following CPB. Aprotinin, as an antiiflammatory agent, may decrease the release of such vasoactive substance from pulmonary tissues, preventing pulmonary hypertension after cardiopulmonary bypass. MATERIAL AND METHOD: Ten mongrel dogs(Bwt. ac. 20kg) were subjected to cardioupulmonary bypass for 2 hours and postbypass pulmonary vascular resistance(0, 1, 2, 3 hours) were compared with prebypass level. The dogs were divided into 2 groups; control group(n-5) and aprotinin group(n=5). In the aprotinin group, aprotinin was administered as follows; 50,000 KIU/kg mixed in pump priming solution, 50,000 KIU/kg prebypass intravenous infusion over 30 minutes, 10,000 KIU/kg/hour postbypass continuous infusion. Prebypass and postbypass 0, 1, 2, 3 hour pulmonary vascular resistance were measured. At prebypass and postbypass 0, 90, 180 minutes, blood samples were obtained from pulmonary arterial and left atrial catherers for the assay of plasma thromboxane B2 a stable metabolite of thromboxane A2, and endothelin-1 concentrations. RESULT: The ratios of pustbypass over prebypass pulmonary vascular at postbypass 0, 1, 2, 3 hours were 1.28+/-0.20, 1.82+/-0.23, 1.90+/-0.19, 2.14+/-0.18 in control group, 1.58+/-0.18, 1.73+/-0.01, 1.66+/-0.10, 1.50+/-0.08 in aprotinin group ; the ratios gradually increased in control group while decreased or fluctuated after postbypass 1 hour in aprotinin group. There was statistically significant difference between control group and aprotinin group at postbypass 3 hours(P=0.014). Pulmonary arterial plasma concentration of thromboxane B2(pg/ml) at prebypass, postbypass 0, 90, 180 minutes were 346.4+/-61.9, 529.3+/-197.6, 578.3+/-255.8, 493.3+/-171.3 in control group, 323.8+/-118.0, 422.6+/-75.6, 412.3+/-59.9, 394.5+/-154.0 in aprotinin group. Left atrial concentrations were 339.3+/-89.2, 667.0+/-65.7, 731.2+/-192.7, 607.5+/-165.9 in control group, 330.0+/-111.2, 468.4+/-190.3, 425.4+/-193.6, 4.7.3+/-142.8 in aprotinin group. These results showed decrement of pulmonary thromboxane A2 generation in aprotinin group. Pulmonary arterial concentrations of endothelin-1(fmol/ml) at the same time sequence were 7.84+/-0.31, 13.2+/-0.51, 15.0+/-1.22, 16.3+/-1.73 in control group, 7.76+/-0.12, 15.3+/-0.71, 22.6+/-6.62, 14.9+/-1.11 in aprotinin group. Left atrial concentrations were 7.61+/-17.2, 57.1+/-28.4, 18.9+/-18.2, 31.5+/-20.5 in control group, 5.61+/-7.61, 37.0+/-26.2, 28.6+/-21.7, 37.8+/-30.6 in aprotinin group. These results showed that aprotinin had no effect on plasma endothelin-1 concentration after cardiopulmonary bypass. CONCLUSIONS: Administration of aprotinin during cardiopulmonary bypass could attenuate the increase in pulmonary vascular resistance after bypass. Inhibition of pulmonary thromboxane A2 generation was thought to be one of the mechanism of this effect. Aprotinin had no effect on postbypass endothelin-1 concentration.

BACKGROUND: The hemiepiphyseal stapling has both positive and negative effects on effective leg length. The purpose of this study was to analyze change in effective leg length after angular correction by hemiepiphyseal stapling, and to validate in clinical cases. METHODS: Mathematical analysis of a hemiepiphyseal stapling model was conducted. The induced formula was validated in 6 cases fulfilling the assumptions of the model. Anatomical parameters involved in this formula were measured in additional 21 cases undergoing hemiepiphyseal stapling or hemiepiphysiodesis. RESULTS: Effective leg length increased or decreased according to three parameters in this model: 1) limb length distal to the operated physis (L), 2) width of the operated physis (d), and 3) the amount of angular deformity to be corrected (theta). Actual change in effective leg length of 6 cases similar to this model coincided with the predicted change at least in its direction. L/d ratio was 4.82 +/- 0.51. CONCLUSIONS: Considering the narrow range of the L/d ratio, hemiepiphyseal stapling is likely to decrease effective leg length if the amount of angular correction is less than 10degrees, whereas to increase it if the amount of angular correction is larger than 16degrees. This should be taken into consideration when selecting the surgical method for angular deformity correction in skeletally immature patients.

BACKGROUND: Type 2 diabetes mellitus is an expensive chronic metabolic disorder and its prevalence has been increasing rapidly in South Korea, owing to a westernized lifestyle. We analyzed the annual direct medical costs attributable to type 2 diabetes and its chronic complications in Korea retrospectively. METHODS: We randomly selected 1,051 patients with type 2 diabetes who visited Ajou University Hospital as an outpatient in 2005. Clinical characteristics, duration of diabetes, and microvascular and macrovascular complications were assessed from a medical chart review. The annual direct medical costs included insurance covered and uncovered medical costs. RESULTS: Of the 1,051 patients with type 2 diabetes, 48.2% had at least one microvascular complication, 5.6% had at least one macrovascular complication, and 12.4% of the patients had both microvascular and macrovascular complications. The average annual direct medical cost was found to be 3,348,488won per patient. In patients with microvascular complications, the total cost of management was increased 1.4 times compared to those without complications. Direct medical costs for patients with macrovascular complications were 2.1-fold as high as patients with no complications. Those patients with both microvascular and macrovascular complications, increased costs by 3.1-fold over those without complications. CONCLUSION: Chronic complications have a substantial impact on the direct medical costs of type 2 diabetes. The prevention of chronic diabetic complications will not only influence the mortality and morbidity of patients with type 2 diabetes, but also potentially reduce medical costs.

Behcet? disease is a recurring illness characterized by the triple symptom complex of aphthous stomatitis, genital ulceration, and uveitis. The disease is multisystemic disorder with involvement of skin, gastrointestinal tract, blood vessels, central nervous system, joints, and epididymis. Vascular involvement of Behcet? disease affects both arteries and veins and blood vessels of all sizes. Periosteal new bone formation is one feature of hypertrophic osteoarthropathy. Other features are clubbing and arthritis. Periosteal new bone formation on the bones of the lower extremities without other features of hypertrophic osteoarthropathy has been reported in patients with varicose veins, vitamin A intoxication, infantile cortical hyperostosis, tuberous sclerosis, congenital syphilis and chronic renal failure with hyperparathyroidism, and chronic venous insufficiency. However, periosteal new bone formation has not, to our knowledge, been described in patients with Behcet? disease yet although similar findings are occasionally noted in polyarteritis nodosa. We report a case of Behcet? disease complicated by leg swelling with periosteal new bone formation of right lower leg.
