The pedicled fillet flap concept has been successfully applied in both the upper and lower extremities for the treatment of difficult wound. In cases of inevitable extremity amputation, the transfer of pedicled flap from the amputed part is possible. In such substance, it is possible to obtain the pedicled fillet flap from the amputed limb to provide stump coverage. We experienced two cases of below-knee amputation due to severe flame burn which the stump was covered with island pedicled sole-fillet flap.

It is indispensable to cover the skin defect when bone or tendon is exposed. In case of inevitable amputation of an extremity, it is possible to harvest a free flap from the amputed limb for providing coverage of the other wound. This technique allows immediate wound coverage without the morbidity of an additional donor site. We experienced an electrical burn case with inevitahle wrist disarticulation and successfully treated soft tissue defect of ankle using free vascularized flap.

Clinics in Shoulder and Elbow 2016;19(4):237-240
Retear patterns after arthroscopic rotator cuff repair are classified into two patterns according to retear location. Type 1 is when the retear pattern occurs directly on the tendon at the bone repair site using the suture anchor repair method. Type 2 is when the retear pattern occurs at the musculocutaneous junction with a healed footprint in patients who undergo the suture bridge method. Here, the authors report another retear pattern, which was identified as a type 2 retear on magnetic resonance imaging in patients who had undergone arthroscopic rotator cuff repair by the suture-bridge technique. This pattern was different from the type 2 retear and occurred at the portion of the cuff away from the healed rotator cuff under the view of the arthroscope.

Korean Journal of Dermatology 1994;32(5):795-801
BACKGROUND: Although the wet earwax has been known to be related with the incidence of tinea versicolor, very little has been revealed on how they are correlated with each other. The incidence of Malassezia furfur, the etiological organism of tinea versicolor, and its population densities as yearst and mycelial form in the different types of earwax, the dry and the wet, have not been studied. METHODS: The type of earwax in 65 patients with tinea versicolor were classified into 2 types, dry and wet, by its appearence and the subjective complaints of the patients. The dry and wet cerumens were obtained from 142 and 49 individulas without tinea versicolor respectively. The cerumens were stained with 10% Parker ink-KOH solution. The incidence and its population densities of yeast and mycelial M. furfur in the wet cerumens were compared with those in the dry cerumens according to a new grading method using bacterial index(BI) of lepra bacilli. RESULTS: 1. Dry and wet earwax were observed in 58.5%(38 cases) and 41.5%(27 cases) of 65 patients respectively. 2. The incidence of yeast M. furfur in the dry and wet cerumens were 100% and 63.3%(31 of 49 cases) respectively, and that of mycelial M. furfur, 28.2%(40 of 142 cases) and 32.7%(16 of 49 cases) respectively. 3. The population densities(from 3+ to 6+) of yeast M. furfur in the dry and wet cerumens were ob served in 93.0%(132 of 142 cases) and 49.0%(24 of 40 cases), and those(3+) of mycelial M. furfur, 21.1%(30 of 142 cases) and 24.5%(12 of 49 cases) respectively. CONCLUSION: The incidence(41.5%) of wet earwax in tinea versicolor patients is significantly higher than that(0.8%) in The Korean control group. The ratio between the incidence of mycelial M. furfur and that of yeast M. furfur in the wet cerumens is higher than in the dry cerumens, and the ratio of population densities in the wet cerumens is also higher. These observations suggest that the skin surface conditions of the wet earwax group may be more suitable for yeast-mycelial transformation of M. furfur than those of the dry earwax group. The comparison of chemical compositions of the skin surface between dry and wet earwax groups is needed to elucidate the correlation between tinea versicolor and the types of earwax in the future.

Eczema herpeticum occurred in a patient with pemphigus foliaceus and esophageal cancer. The patient's initial skin lesions composed of large flaccid bullaes showed subcorneal bullae with typical acantholytic cells. Subsequent grouped small vesicles appeared widely on the erythematous base were diagnosed herpes simplex virus infection by Tzanck smear and histopathological findings. The patient died one week after the development of the widespread herpes virus infection.

Thirty-five cerebello-pontine angle lesions were diagnosed with simple skull X-ray, CT, and angiography atSeoul National University Hospital from Sept. 1978 through Aug. 1982. The radiographic findings were analysed withemphasis on the differential points of CT among the major three cerebello-pontine angle tumors; acousticneurinoma, meningioma and epidermoid. The results are as follows; 1. Among the 35 cases of cerebello-pontine anglelesions, 19 cases were acoustic neurinoma. 4 cases miningioma, 4 cases epidermoid, 2 cases metastasis, 1 caseschoroid plexus papilloma, 1 case arteriovenous malformation, and 3 cases intra-axial posterior fossa tumors. 2.The characteristic radiographic findings of acoustic neurinoma were windening of internal auditory canal, petrousbone erosion, posterior extension of tumor at the level of internal autidory canal, hypo or isodense mass onpre-contrast CT with high enhancement after intravenous contrast infusion, and cystic change within the mass. 3.Meningioma shows anterior extenstion of the lesion at the level of internal auditory canal, broad base and obtuseangle sign of the lesion with petrous bone, hyperdense mass on precontrast CT. with highly homogeneous enhancementafter intravenous contrast infusion. 4. Epidermoid characteristically shows hypodense mass on precontrast CT withno change after intravenous contrast infusion. 5. The differential points of the major 3 cerebello-pontine tumorswere bone change, mass location, attenuation , degree of attachment to petrous bone, and cystic change.

Capitellar fracture was first described by Hahn in 1853. It is rare, espically in children, and has been occurred 0.5% to 1% of incidence of all elbow injuries. Factures of the capitellum can involve a significant portion of the articular surfaces. It is desirable to reduce and internally fix the capitellar fragment, if possible, because this restores the artucular surface and augment joint stability. Three patients with displaced fractures of the capitellum(capitulum humeri) were treated by open reduction and internal fixation using Herbert screws, which stabilized the joint, allowed anatomical reduction, and gave rigid fixation. Postoperatively, early motion of the joint was allowed. All fractures were united without evidence of avascular necrosis and final follow-up was excellent.

To cover soft tissue defect, various types of flaps have been used. Although lateral supramalleolar flap has been used as rotation flaps or reversed island flaps to cover defects around the foot and ankle, there has been no report about its application as a free flap. The lateral supramalleolar island flap has proves to be supplied constantly by the terminal branch of the peroneal arterys perforating branch. The free lateral supramalleolar flap has the same skin territory. Its vascular pedicle can be extended to the main peroneal artery and vena comitans, which can be obtained by dissecting the peroneal vessels between the distal tibia and fibula through the interosseous membrane. We have successfully transferred this free flap in eight patients from April 1994 to February 1995. All of the patients had full thickness skin defects which were caused by contact thermal burn, electrical burn, flame burn or traffic accident. There were no complications. From our experience, we feel that this new free flap have some advantages, induding vascular anatomy and long pedicle with large diameter and a relatively thin flap with minimal morbidity of donor site.

Journal of the Korean Hip Society 2006;18(1):12-17
Purpose: To investigate the extent of bone ingrowth into the porous-coated acetabular cups as well as the factors that correlated with bone ingrowth in total hip arthroplasty. Materials and Methods: Thirty six Harris-Galante porous-coated acetabular cups that were retrieved through revision surgery were examined in this study. Acetabular cups retrieved due to infection or severely destroyed cups (ed note: severe what?) were excluded. The extent of bone ingrowth into the acetabular cups was grossly measured, and its correlation with the variables including age, gender, weight, height, the duration of fixation, size, number of screws, inclination and anteversion was statistically analyzed. Results: The mean proportion of bone ingrowth was 52.9 21.9%(2~90%) and less than 30% in three cups(8.3%). The pattern and the location of bone ingrowth were not consistent. There was no correlation between the extent of bone ingrowth and age, gender, weight, height, the duration of fixation, cup size, number of screws, size, inclination and anteversion. Conclusion: Harris-Galante porous-coated acetabular cups showed satisfactory bone ingrowth regardless of the variables associated with the demographic or surgical conditions. Surface treatments with a fiber-metal porouscoating appears to be suitable for cementless acetabular cups in terms of the long term results.
