Ki-1 lymphoma is a rare, large cell anaplastic non Hodgkin's lymphoma. It expresses the CD30 antigen and is recognized by the antibodies Ki-1. This Ki-1 positive anaplastic lymphoma was first described in 1985 as a new histological subtype and was added to the updated Kiel classification in 1988. Morphological and immunological features of this lymphoma have been well described, but clinical studies have been limited and follow up has been short. The authors report a case of Ki-1 lymphoma of the skin without systemic involvement in a young adult based on clinical, pathological and immunological features.

BACKGROUND: Immediate implant placement has become an acceptable treatment for the edentulous area. The advantages of the immediate implant placement include considerable decrease in time from tooth extraction to placement of the finial prosthesis, fewer surgical procedures, and better acceptance of the overall treatment plans. But the success is dependent on the quantity and quality of the extraction socket. The purpose of this study is to evaluate the success of the immediate implant placement. MATERIALS AND METHODS: Twenty-one sites in 16 patients were selected for the evaluation of the immediate implant placement. All of the cases were followed using clinical and radiographic examinations. Criteria of success were the absence of peri-implant radiolucency, mobility, and persistent pain or sign of infection. RESULTS: Of the 21 implants, 13 implants have been succeeded. Of the 13 implants, 10 implants were replaced for the periodontal disease and 3 implants were replaced for the trauma. CONCLUSION: The criteria of the success in immediate implant placement are as follows. 1) Implants placed into fresh extraction sockets have a high rate of survival. 2) Implant should be placed as close as possible to the alveolar crest. 3) Implant placed into available bone beyond the apex have a high success rate.

Takayasu's arteritis is briefly as an inflammatory process of unknown etiology occuring dominantly in young female most commonly involving the great vessels arising from the aortic arch. The disease process results in stenosis and obliteration of involved vessels. Syncope in Takayasu's arteritis is known to result from decreased blood flow to brain because of stenosing blood vessels. We herein describe a case of paroxysmal atrioventricular block in a 40-year old man with Takayasu's arteritis. The patient presented with spontaneous recurrent syncope associated with paroxysmal AV block. Carotid sinus pressure repeatedly induced paroxysmal AV block and syncope. Carotid sinus pressure after pretreatment of atropine failed to induce AV block or syncope. Coronary angiogram was normal. We concluded that syncope in this patients was attributed to carotid hypersensitivity rather than decreased blood flow to the brain due to vessel stenosis.

The principle of surgery of the parotid gland is adequate removal of the tumor with functional and anatomical preservation of all blanches of the facial nerve. There are two main surgical approaches to superficial or total conservative parotidectomy. Anterior approach and posterior approach. Preliminary identification of the main trunk of the facial nerve is probably the most favoured techniques, but identification of the peripheral blanches of the facial nerve, with subsequent Proximal dissection to the main trunk, is long established but less popular technique. We have prospectively experienced the low incidence of facial nerve damage in series of 55 conservative parotidectomies performed using the anterior approach. The techniques employed is described with a deport of results obtained in the belief that this approach warrants greater popularity and saute technique.

Fibular fractures that begin proximal to the tibial plafond are assumed to include an injury of the syndesmosis. Many surgeons have treated this injuries by rigidly repairing the medial and lateral malleoli with trans-syndesmotic fixation. However, recently, some demonstrated that a trans-syndesmotic screw places biomechanical restrictions on the tibiotalar joint and is not required to maintain the integrity of the distal tibiofibular joint in cadava models. Thirty eight patients of ankle fracture with syndesmotic injury treated at Sun General Hospital from January 1989 to June 1994 week analyzed in clinical and radiologic aspect. The results obtained from this study were as followings. 1. If rigid anatomic medial and lateral joint fixation was obtained, syndesmotic screw fixation was not required to maintain the integrity of the syndesmotic. 2. Repairting the deltoid ligament did not enhance treatment results when fibular fracture and syndesmotic had been fixed anatomically. Therefore, we believe that syndesmotic screw fixation was indicated only when medial and lateral stabilization could not be achieved adequately.

The incidence of uterine prolapse during pregnancy is rare. A 34-year-old G3P1 was initially presented at 16 weeks 5days of gestation with a prolapse of the uterine cervix. The cervix was edematous and protruding beyond introitus. Management included bed rest, and the patient was discharged after several days with a vaginal pessary to help maintain cervical placement. At 35 weeks of gestation, the patient did not experience any further prolapse after the removal of the pessary. Pregnancy progressed to term with no further prolapse. She was readmitted at 38weeks 5days of gestation with spontaneous labor. She delivered a 3.36kg male with an Apgar score at 1 minute and at 5 minutes of 7 and 8 respectively. The patient's cervix remained prolapsed in the early postpartum period; however it was easily reduced prior to discharge. After puerperium, the patient's cervix remained prolapsed. She was fitted with a vaginal pessary for uterine support. We reported this case with related literature.

OBJECTIVE: To evaluate the changes of maximum fibrillation potential amplitude and root- mean-square (RMS) value of denervation potential after nerve injury using power spectrum analysis. METHODS: The sciatic nerve was transected in 8 rats, and was compressed in 6 rats. Denervation potentials were collected in gastrocnemius using monopolar needle weekly after nerve injury. The change of RMS value of 1 second epoch of denervation potentials with time was evaluated and compared with the change of maximun fibrillation potential amplitude. RESULTS: In nerve-transected rat, the RMS value declined linearly with time after injury. On the contrary, the amplitude of fibrillation potentials declined much rapidly during first 3 weeks. In nerve-compressed rat, both the RMS value and amplitude of fibrillation potential increased for 2 weeks after injury, and declined thereafter. As the result of simple regression analysis, the changes of RMS value correlated better than changes of fibrillation amplitude in all 8 nerve-transected rat. CONCLUSION: The RMS value of denervation potentials correlated well with time after nerve injury in animal experiments. Measurement of the RMS value might be helpful to evaluate the time after peripheral nerve injury, but long-term human data should be essential for clinical application.
