A 13 years old girl came to our department with complaints of multiple ulcerating and non-ulcerating nodules on her back and buttocks since 1 month prior to visit. Skin biopsy specimen showed diffuse monomorphous infiltration of leukemic cells in the dermis and subcutis. Bone marrow biopsy specimen showed changes of erythroleukemia. Treatment was initiated with combined chemotherapy which was a combination of cytosine arabinoside, adriamyein and 6 thioguanine. When combined chemotherapy was finished, she was in complete remission state and the nodules cured after 1 month of combined chemotherapy.

Report. about numeric change of LC between vitiliginous skin(VS) and adjacent normal appering skin (ANAS) are hard to find, Epidermal Langerhans Cell (LC) dersities in VS and ANAS were studied in 18 patient with generalized vitiligo. Adenosine triphosphatase(ATPase) stain was used to characterize LC. Epidermal LC densities were calculated by means of an eye piece reticule and expressed per mm. The results were as follows; 1. The was significant body site variation of LC densities in ANAS and the range of densities of LC per mm were from 668+165 to 1,241 _3 and the mean density of LC per mm was 944+258. 3. The LC densities of VS was similar to that of ANAS(p: not significant). In conclusion quantiative change of epidermal LC in vitiligo doesn't seem to have significant relation with pathogenesis of vitiligo.

Ninety black C 57 BL mice were divided into control and photochemotherapy groups. Control group was subdivided into a UVA 1rradiation only subgroup and a khellin only administration subgroup, while the phototherapy group was subdivided into one TMP and two khellin administration subgroups with dosages of 1.5mg/kg, 5mg/kg and 20mg/kg, respectivly. UVA was administered three thimes a week in a dose of 4J/cm for 4 weeks. Skin biopsies were taken at 0, l, 2, 3 and 4 weeks and the split DOPA stain was employed to observe pigment production. The number, size and circumference of the melanocytes were assessed. In summary, our results inclicate that khellin, which is slightly less effective than TMP at the same effective dose, is quite effective for pigment production and the degree of the production is dose related.

RePUVA therapy is the combination of an oral aromatic retinoid(etretinate) with oral photochemotherapy (PUVA) for the treatment of psoriasis. This combination therapy has the advantage of faster clearance with fewer side effects. Twenty three ambulatory psoriasis patients received RePUVA treatment. Etretinate was administered in a dosage of approxirnately 0.75 mg/kg body weight for 2 weeks and discontinued. One week after discontinuance of etretinate, PUVA therapy was begun. Complete clearance occured in 96% of the patients with an average of 9.5+4 irradiations and an accumulated ultraviolet A (UVA) dose of 67.5+42 J/cm. The primary side effects were dry rnucous membranes and mild cheilitis. Laboratory findings revealed no significant abnormalities before or after etretinate treatment.

Since the introduction of percutaneous mitral valvotomy(PMV) in 1984, PMV was an effecive alternative to surgical commissurotomy in selected patients with severe mitral stenosis. Also PMV was an excellent palliative strategy in such patients who were high risk for operative management or longterm anticoagulation was not feasible. We performed PMV in a patient with very tight mitral stenosis and severe pulmonary hypertension under the general anesthesia because the patient was anticipated to be uncooperative due to mental problem, who was diagnosed as schizophrenia 16 years ago. Robinol was used for premedication and i.v fentanyl was used for maintenance of anesthesia. Inoue balloon was introduced into the LV and gradual ballooning was performed with favorable results. Total anesthesia time and interval from internal jugular vein puncture to the completion of valvuloplasty were 1 hour 45 min and 40 minutes respectively. Hemodynamic variables were improved immediately after intervention and mitral valve area was increased from 0.5cm2 to 1.3cm2.

Allergic contact dermatitis due to 8-MOP is a rarely known si(ie effect of this widely used drug. Other known adverse reactions due to 8-MOP such as the oallergic dermatitis as well as some isolated cases of exanthema, papular eruptions, and astloma like symptoms are also sporadically reported. A 52-year-old man with vitiligo developed erythema to the UVA exposed 0.3% Oxoralen cream applied area. Prior to this episode, the patient had history of generalized burns after systernic PUVA therapy in 1983. Even after this experience, the patient had few more episodes of erythema at the site of 0.3%. Oxoralen cream application. We performed patch test and photopatch tests with Scandinavian series, 0.3% Oxoraler or am (as is), and diluted 8-MOP, 5-MOP, TMP solution. The result showed positive reactivity to 6-methylcoumarin, 8-MOP, as well as to 0.3% Oxoralen cream. The size of erythema was same in both irradiated areas which indicates an allergic contact dermatitis rather than photoallergic dermatitis or phototoxic dermatitis.

Porokeratosis is an uncommon autosomally dominant inher ted disorder. Clinically, it is characterized by nonhealing plaques that develop most comnorly on the limbs. We report a case of disseminated superficial porokeratosis in immunosuppre sed kidney transplant recipient. An abrupt and extensive eruption of porokeratosis was observed in a 46-year-old man 7 months after renal transplantation, while being treated with cyclosporin A and prednisone. The histological features were essentially the same as the typical cornoid lamella. Immunosuppression may exacerbate or initiate the developm nt of porokeratosis in patients predisposed to alterations of cutaneous growth dynamics.

PURPOSE: Abnormalities in calcium(Ca), vitamin D and bone mineral density (BMD) associated with antiepileptic drug(AED) are reported, but the results are inconsistent. In case of intractable epilepsy, poor growth and altered bone mineral metabolism may be prominent, possibly related to previous long-term use of multiple AED and poor activity. The aim of this study was to assess growth status, concentrations of calcium regulating hormones and BMD in children with intractable epilepsy. METHODS: Sixty-six intractable epilepsy patients aged 0.8 to 14.7 years(mean+/-D:4.6+/-.6 years) were included in the study. Height and weight were measured and then height SDS and weight SDS were calculated. Serum Ca, i-Ca, P, Mg, Zinc, osteocalcin, intact-PTH, 25-OHD, 1,25(OH)2D were measured. BMD of the lumbar spine was measured by dual energy X-ray absorption. RESULTS: Most of the patients showed normal height SDS and weight SDS. Percentage of severe short stature(height SDS <-2) was 1.5% and tall stature(height SDS >2) was 4.5%. Percentage of severe thin(weight SDS <-2) was 1.5% and obesity(weight SDS >2) was 6%. Duration of AED was not related to height SDS or weight SDS. Etiology of epilepsy and physical activity were not related to height SDS and weight SDS. Most of them had normal Ca, iCa, P, Mg, Zinc, intact-PTH, osteocalcin, 25-OHD and 1,25(OH)2D concentrations. BMD was not related to the levels of Ca, i-Ca, P, Mg, intact-PTH, osteocalcin, 25-OHD, 1,25(OH)2D. BMD was not related to the duration of AED. BMD positively correlated with age(r=0.75, P>0.01) and body weight(r=0.72, P<0.01). CONCLUSION: Most of the children with intractable epilepsy, who regularly visits epilepsy clinic, showed normal growth and normal bone mineral metabolism, but careful monitoring about growth and bone mineral metabolism is needed.
