4.Lower incisor extraction for dental camouflage.
Korean Journal of Orthodontics 1997;27(4):661-668
There is a variation in the range of normal occlusion, and we must fit our treatment to the needs of each patient. If the upper or lower incisors are congenitally missing, malformed, or crowded, the extraction of the incisor has some advantages over the extraction of premolars and nonextractions. The advantages are l) simple mechanics, 2) reduced treatment time, 3) less relapse tendency, and 4) fewer facial profile changes. In order to decide which incisor should be extracted, we must consider certain factors: l) discrepancies in anterior arch length, 2) anterior tooth ratio, 3) periodontal and tooth health condition, and 4) the relationship between the upper and lower midline. Diagnostic set-up can be helpful to plan the treatment and show us the post treatment result.

Chloramphenicol ophthalmic solut,ion is a commonly used eye drui in the treatment of superficial eye infection because of its wide antibacterial spectrum and easy peitation in the ocular tissue and aqueous humor. The true contact dermat it is to chloramphenicol is rarely reported. A case of contact. dermatii,is due to chloramphenicol in a 6-year-old girl was confirmed by the patch test. Marked improvement of the skin lesion and symptoms were rated after the withdrawal of topieal application of the chloramphericol ophthalmic solution.

A 24-year old woman presented with hemorrhagic vesicles on her legs. She had taken sibutramine (Reductil(R), Abbott Labs., Seoul, South Korea) for 3 months and developed skin lesions the week before. A skin biopsy showed leukocytoclastic vasculitis with conspicuous eosinophilic infiltration of the tissue. These lesions showed improvement after discontinuation of sibutramine. However, 3 months later the skin lesions recurred on other sites on the lower extremities when the patient was rechallenged with the same drug for 2 weeks. Herein, we report the first case of necrotizing vasculitis induced by sibutramine.

BACKGROUND: It is well-known that the giant congenital nevi prcgress to malignant, melanama more frequently than other benign melanocytic nevi but to date the laor tory methods for early detection of such progression were not avsilable. The proliferating cell uncleai antigen(PCNA) staining has been regsrded as an useful marker in determining prognosis of some maignant diseases. OBJECTIVE: The PCNA taining was performed as a predictive value of malignant transformation from benign meanocytic skin lesions. We investigated the differcnces between malignant melanoma and the benign lesions. MATERIAL AND METHODS: Immunohistochemical study was employee using anti-PCNA, anti-S-100, and anti-CD45RO antibody in 6 giant congenital nevi, 8 small and medium sized congenital nevi, 10 acquired nevi, and 10 malignant meanomas. Only cells positive for both PCNA and S-100, and negative for CD45RO on the serial sections were identified as melanocyts. RESULTS: The number of PCNA-posit,ive cells per 1000 melanocy,es averaged 6.0+7.5 in giant, congenital nevi, 2.9+1,9 in small and medium sized congenital novi, 3.1+2.7 in acquired nevi, and 61.5+ 39.4 in malignant, melanomas. Malignant melanomas showed onger intensity of PCNA staining than the other melanocytir nevi. CONCLUSION: There was not significant difference of the numter of PCNA-positive cells among the groups of congenital neviind PCNA staining can't be used in prditive measure of malignant. progression and studying mechansm of malignancy in giant congenital nevi. But, PCNA staining is considered as an useful method in differentiat,ing malignant melanoma from mllanocytic nevi.

9.Comparative Study of Calcipotriol and Desoxymethasone Ointments in the Treatment of Psoriasis Vulgaris: The Clinical Effect and Immunohistochemical Change.

BACKGROUND: Calcipotrol, topical vitamin D analogue, has been demonstrated to have an effect for the treatment of psoriasis with good tolerability. It is required to have comparative studies with the other topical agents which are widely used for the treatment of psoriasis. OBJECTIVE: Our purpose is to compare calcipotriol with desoxymethasone ointemtn in their therapeutic efficacy and ability to affect dermal inflammatory cellular events. METHODS: This study was a randomized, double blind, right/left comparison over 8weeks in 10 patients. The ointments were applied twice daily to the lesions of psoriasis. Clinical efficacy, as measured by the Psoriasis Area and Severity Index(PASI) was assessed at 2, 4, 6 and 8weeks after starting treatments. The changes in the numbers of dermal immunocytes were assessed on frozen and paraffin-embedded sections by using immunohistochemical stain methods before and after the treatemtns. RESULTS: Reduction of PASI was statistically significant at all time points for both of the treatments (P<0.01) but there was no significant defference between the two treatment modalities. At the completion of 8 weeks of treatments, the mean PASI reduction was 65 percents and 67 percents for calcipotriol and desoxymethasone ointments, respectively. On immunohistochemical staining, the numbers of LCA and HLA-DR positive cells were decreased significantly(P<0.05), and IL-2R and CD4 positive cells were not significaltly reduced in each group after the treatment. CONCLUSION: Calcipotriol ointment was as effective as desoxymethasone ointment, judged by the PASI and the dermal inflammatory cellular events on immunohistochemical staining.

In the case of a soft tissue defect which requires thin & pliable tissues, the choice of donor site is limited due to flap bulkiness and donor site morbidity. To overcome these problems, a variety of perforator-based flaps such as paraspinous and parasacral perforator flap, deep inferior epigastric perforator flap, gluteal perforator flap, and thoracodorsal artery perforator flap have recently been introduced. We experienced 8 cases of soft tissue defects from December 1996 to March 1999 using the thoracodorsal artery perforator flap for reconstruction. We could elevate the cutaneous flap with preservation of the latissimus dorsi muscle flap only when it was based on one cutaneous perforator. Defatting procedure was possible for further thinning of skin flap. In one case, axillary defect after release of postburn scar contracture was repaired with island perforator flap and the other seven cases were repaired with free flap. The results were satisfactory. We believe the thoracodorsal artery perforator flap is useful for reconstruction of soft tissue defects which are large or under conditions requiring thin flap.
