Augmentation mammoplasty can be done in various manners according to the way of approach. the type of implant or implatation site depending on the status and demand of the patients or the operator's preferrence. In reviewing the many published reports about augmentation mammoplasty, they compare their surgical outcomes with mixed factors, so it is difficult to compare the results of mammoplasty simply with one factor under the same conditions. We think that analyzing the surgical results with one consistent method enables to compare and decide the influencing effect of one factor within it in augmentation mammoplasty. We could find the fact that the Korean women who wanted augmentation mammoplasty had same physical characteristics and demands, so developed the standardized method of augmentation mammoplasty among those debatable data for the purpose of increasing the patients' satisfaction, decreasing the complications, and shortening the operation time. The method we adopted was placing the implant through transaxillary subpectoral approach and using the endoscope auxiliarily in additional dissection and hemostasis. We employed saline-filled implants of round, textured type with the size ranging fro 125cc to 175cc and overinflated them by 10 to 30% beyond its original volume. After irrigation of the dissected pocket, we placed the suction drainage system into the subpectoral pocket. We educated the patients to massage their breasts right after removal of the drain. During the period of follow-up (from 6 months to 24 months), most of the patients were satisfied with their operative results. Though we experienced one case of capsular contracture, one case of malposition of the implant, and three cases of scar contracture on axillar incision site, as a whole, we could minimize the complications associated with augmentation mammoplasty. We present our postoperative results with the conclusion that our standardized method of augmentation mammoplasty can bring results of high satisfaction rate, minimal complication, predictability of postoperative results, shortening of operation time when applied consistently to the Korean patients whose physical characteristics are similar. We also hope that stanadardized method can be used to compare the influencing effect of many factors in the case of changing one factor within the standardized in the future follow up period.

PURPOSE: The purpose of this study was to examine the significance of increased bone density according to whether bone grafts were applied using demographic data with Cone Beam Computed Tomography (CBCT) and to compare the bone densities between before and after implant prosthesis using the Hounsfield index. MATERIALS AND METHODS: Thirty-six randomly selected computed tomography (CT) scans were used for the analysis. The same sites were evaluated digitally using the Hounsfield scale with V-Implant 2.0(TM), and the results were compared with maxillary posterior bone graft. Statistical data analysis was carried out to determine the correlation between the recorded Hounsfield unit (HU) of the bone graft and implant prosthesis using a Mann-Whitney U test and Wilcoxon Matched-pairs test. RESULTS: The bone grafted maxillary posterior teeth showed an increase in the mean values from-157 HU to 387 HU, whereas non-grafted maxillary posterior teeth showed an increase from 62 HU to 342 HU. After implantation, the grafted and non-grafted groups showed significantly higher bone density than before implantation. However, the grafted group showed significantly more changes than the non-grafted group. CONCLUSION: Bone density measurements using CBCT might provide an objective assessment of the bone quality as well as the correlation between bone density (Hounsfield scale) and bone grafts in the maxillary molar area.

Primary pulmonary hypertension is a rar, incurable, and progressive clinical entity. When associated with pregnancy, the prognosis of primary pulmonary hypertension is worsened with maternal mortality rates of at least 50%. The patient was a 29-year-old mother in her 2nd pregnancy, with previous uncomplicated gestation, 5 years ago. She had been well until the 28th week of present gestation when she was admitted because of increasing dyspnea on exertion. She was a housewife with no remarkable family and past histories. We have experienced a patient with primary pulmonary hypertension in pregnancy. She was treated with an oral calcium-channel blocker and low-molecular-weight heparin and was delivered vaginally with good maternal and fetal outcome. So we report a case of primary pulmonary hypertension associated with pregnancy and review literature.

Virus associated hemophagocytic syndrome, class ll histiocytoses, characterized by high fever, severe constitutional symptoms, abnormal liver function and coagulation, perigheral blood pancytopenia and histiocytic hyperplasis with prominent hemophagocytosis in bone marrow and lymph nodes has been reported and associated with active viral infection. It is non-malignant and reversible. It must be differentiated from histiocytic medullary reticulosis because of the inappopriateness of immunosuppressive of cytotozic therapy which is the therapeutic method for HMR, but is contraindicated in the treatment of VAHS. This paper describes two patients whose clinicopathology was compatible with the diagnosis of virus associated hemophagocytic syndrome.

Mucormycosis is an opportunistic fungal infection caused by the mucorales, which consist of the Rhizophus, Absidia, Mortierella, and Mucor. The diverse clinical forms of mucormycosis can be categorized as rhinocerebral, pulmonary, disseminated, gastrointestinal, cutaneous and miscellaneous. Although it can cause disease in healthy people, it most commonly affects patients who are diabetic or immunosup-pressed. Rarely, mucormycosis develops confined to the subcutaneous tissue. We experienced a case of cutaneous mucormycosis developed in a well-controlled diabetic patient who had previously injected foreign material on her face for an aesthetic purpose at the behest of an unlicensed physician. The patient had tissue necrosis and purulent discharge on her left cheek. Following histologic examination, we diagnosed the condition as cutaneous mucormycosis and treated it by wide excision combined with amphotericin B therapy. The disease was cured without any significant sequelae within 6 months of follow up. Cutaneous mucormycosis is rarely reported but it can cause facial deformity due to tissue necrosis, so that early diagnosis and appropriate treatment are important. Currently, foreign material injection for aesthetic purposes is still performed by unlicensed physicians. We present a case report concluding that one should consider the possibility of fungal infection in skin lesion in diabetic or other immunosup-pressed patients. We also emphasize the seriousness of illegal injection of foreign material.

The most important basic requirements for successful skin grafting are the accurate approximation of the edge of the skin graft to that of the wound and the application of even pressure to the graft by a carefully designed dressing. Pressure dressing is indicated for the protection of the graft and the prevention of shearing between the graft and its bed. One of the most widely used methods of pressure dressing is tie-over dressing. The traditional technique is based on the application of long silk sutures along the margin of the graft that are tied over bolus of antibiotics oint-impregnated nonadherent fluffed gauze. With the traditional tie-over dressing, it is impossible to inspect the graft bed for possible hematoma and seroma during the application of dressing. So we adopted another modification of the previously described tie-over dressing methods. From January 1997 to July 1997, we had performed 27 skin graft surgeries and 8 subdermal shavings in 35 patients with our new method of tie-over dressing. We can apply even pressure to the grafts by twisting the long silk sutures instead of typing.In comparison with the plethora of devices and techniques described previously in tie-over dressing construction, our technique offers simplicity and reliable fixation of the graft to the bed and allows further adjustment of the dressing by individual tightening of the threads. Other particularly attractive features are the ability to inspect the graft at any time with little difficulty and the reapplicability of tie-over dressing with the remaining long threads if needed.

PURPOSE: To assess the utility of shoulder MRI by using ROC (receiver operating characteristic) curve in theevaluation of rotator cuff tear, anterior labral tear, superior labral tear and Hill-Sachs Lesion. MATERIALS AND METHODS: We evaluated 38 arthroscopically confirmed patients who had undergone shoulder MRI. According to thesignal intensity of the rotator cuff, as seen on T2 and proton density imaging, a five-stage grading system wasdevised. Labral tears were graded according to the separation of the labium; this was based on gleaned,morphologic and signal intensity changes of the labrum : six grades of anterior labral tear and three grades ofsuperior labral tear. Hill-sachs lesion was also classified into four grades according to morphologic and signalchanges of the humeral head. These findings were reviewed by two musculoskeletal radiologists and ROC curves andareas under the curve (Az) was abtained. RESULTS: The ratio of area under the curve of rotator cuff tear,anterior labral tear, superior labral tear and Hill-Sachs lesion were 82.4%, 88.%%, 62.4% and 91.3%, respectively. CONCLUSION: The Accuracy of shoulder MRI using ROC curve was relatively high in rotator cuff tear, anteriorlabral tear and Hill-Sachs lesion, but low in superior labral tear.
