Entrapment syndrome of suprascapular nerve by a ganglion has been reported not frequently. We experienced a case of suprascapular nerve entrapment by ganglion which was treated with non-operative treatment, and report it with literature.

Although a number of remedies like corticosteroids, retinoids, griseofulvin, PUVA, cyclosporine, antibiotics, dapsone, cyclophosphamide, surgery, methotrexate, radiation therapy, antimalarial drugs, psychotharapy and psychiatric medications have been used to treat lichen planus, there were no specific methods until now. We report herein an interesting case of lichen planus in which complete healing was achieved by griseofulvin administration. The patient was a 54-year-old male who for 3 months had variouly sized and shaped, flat-topped, scaly, violaceous papules and plaques on the whole of his body. We confirmed the patients disease as lichen planus by a histopathologic examination of a skin biopsy specimen and gave him 500mg ultramicronized griseofulvin daily in divided dosages. After 12 weeks of the medication nearly all of the skin lesions were regressed, and by 14 weeks all skin lesions had disappeared leaving hyperpigmentation. Up to now, l9 months after discontinuation of the medication, no recurrence of the disease has been noted.

Platelet-rich plasma (PRP) has been known to increase the rate and degree of bone formation by virtue of growth factors in concentrated platelets. Although its great healing effect on bone defect or pre-implantation site preparation in conjunction with bone substitute has been reported, the effect associated with implant is unknown. The purpose of this study was to investigate the effect of PRP on rapid osseointegration of endosseous dental implants in the rabbit tibiae. Twenty two adult female New Zealand white rabbits, weighing approximately 2.7-3.3kg, were used for this study. Twelve of the 22 animals were used for histomorphometric analysis and ten of the 22 were for removal torque test. Each animal received two implants in each tibia (two treated with PRP and two as control) and was given fluorochrome intramuscularly. For histomorphometric analysis, rabbits were divided into four groups according to the healing period. At 1 week, 2 weeks, 4 weeks and 8 weeks postoperatively, each three animals were sacrificed serially and the amount and rate of bone formation around dental implant were examined on the undecalcified sections under fluorescent microscope, polarized microscope and light microscope connected to a personal computer equipped with image analysis system. For removal torque test, rabbits were divided into two groups and removal torque tests were performed at 4 weeks, 10 weeks after implant placement. In total, 88 screw shaped, commercially pure titanium implants (Neoplant, Neobiotech, Seoul, Korea) were used in this study. Labeling pattern reflected differences of two groups in bone formation rate at each period. Histomorphometrically, PRP group showed significantly higher bone volume within threads compared to control group at 2 weeks (70.30+/-4.96% vs. 50.68+/-6.33%; P<.01) and 4 weeks (82.59+/-5.94% vs. 72.94+/-4.57%; P<.05). PRP group at 1, 2 and 4 weeks revealed similar degree of bone volume formation comparable to control group at 2, 4 and 8 weeks, respectively. On the other hand, while PRP group showed higher bone-implant contact (47.37+/-8.09%) than control group (33.16+/-13.47%) at 2 weeks, there were no significant differences between PRP group and control group for any experimental period. Removal torque values also showed no significant differences between PRP group and control group at any experimental period (P>.05). These findings imply that PRP could induce rapid, more bone formation around implant during early healing period and get faster secondary stability for reducing healing period, though it has not induced bone maturation enough to resist functional loading.

PURPOSE: To investigate the role of porous polyethylene sheet in preventing the recurrence of ptosis after frontalis sling with Prolene(R) and the safety of porous polyethylene sheet. METHODS: Prolene(R) was placed subcutaneously in the thigh of white rabbits. In one group, Prolene(R) was placed with porous polyethylene sheet (treated group) and in the other group, Prolene(R) was placed without porous polyethylene sheet (control group). Prolene(R) was tightened and the loosening of the skin was evaluated at 1, 2, 4 and 8 weeks postoperatively. At the same time, the occurence of complications such as infection, granuloma formation was observed. Histologic examination was done at 2, 4 and 8 weeks postoperatively. RESULTS: In the treated group, skin loosening was progressed significantly for 2 weeks (p<0.05, Mann-Whitney U test) but thereafter there was no significant progression. In control group, skin loosening was progressed for 8 weeks (p<0.05, Mann-Whitney U test). Skin loosening was more severe in the control group at each follow-up evaluation (p<0.05, Wilcoxon signed ranks test). No complication was observed during the follow-up period of 8 weeks. On histologic examination, inflammatory reaction and fibrosis ere seen around Prolene(R) in the control group and fibrovascular ingrowth into the pores of porous polyethylene sheet was seen in the treated group. CONCLUSIONS: This study shows that porous polyethylene sheet can be safely used to prevent the slippage of Prolene(R) and the use of porous polyethylene sheet will be helpful in preventing the recurrence of ptosis after frontalis sling with Prolene(R).

A 5-month-old male infantshowed greasy sealy papules on the scalp, dirty scaly papules on the trunk and scaly petechial papules on both the palms and soles since birth. When admitted to the hospital, the patient exhibited lymphadenopathy, hepatomegaly, abdominal distension, mild fever and skin eruption. The biopsy specimens from the skin and lymph node showed an infiltrate composed almost entirely of histiocytic cells with irregularly shaped nuclei and abundant, well demarcated cytoplasm. The histiocytic cells of the infiltrate were proved as Langerhans cells by electron microscopic examination and S-100 protein study. He was treated with methotrexate 30mg/m twice a week and prednisolone 40mg/m daily. Initially skin lesions and general condition were improved, but the patient expired. due to septicemia after 3 months.

Lichen aureus is a variant of pigmented purpuric lichenoid dermatitis. The skin lesions usually appear asymptomatic rusty, copper, or orange colored roundish lichenoid erythematous-purpuric papules and patches on the lower extremities. Histologically, the epidermis shows minimal changes, with a dense lymphohistiocytic infiltrate observed in the superficial derrnis, typically distributed in a band-like fashion. The typical lesion is a single patch localized on the lower extremity. We report a rare case of segmental lichen aureus localized on the right lower extremity.

Bartter's syndrome is a rare tubular disorder characterized by hypokalemic, hypochloremic metabolic alkalosis, hyperreninemic hyperaldosteronism, hyporesponsiveness to pressor agents, and juxtaglomerular apparatus hyperplasia. We report here a case of Bartter's syndrome in a 5 month-old male infant who improved with potassium supplements. In addition to a case report, brief review of related literatures was done.
