OBJECTIVE: To estimate the predictive value of initial serum B-hCG and progesterone measurement for pregnancy outcome in IVF-ET. METHODS: Serum B-hCG at 11-12th day after embryo transfer and progesterone at 7th day after oocyte aspiration were measured in 48 successful pregnant IVF-ET cases from July 1993 to June 1997. RESULTS: Of 48 cases, 26 cases (54.2%) successfully carried to sustaining gestation and 22 cases (45.8%) failed to sustain gestation. The estimated initial serum B-hCG levels in the normal sustaining pregnancy group (132.28+ 22.42 mlU/ml) were statistical significantly higher than 29.43+8.08 mIU/ml in the failed sustaining pregnancy group (p<0.001), while the estimated initial serum progesterone levels showed no significant differences (p=0.159). In order to determine the predictive values using the Receiver Operator Curve (ROC), an appropriate cutoff value of 38 mIU/ml for initial serum B-hCG was obtained. In IVF-ET pregnancies, the estimated serum B-hCG levels in cases of chemical abortion in failed sustaining pregnancy were significantly lower compared to the normal sustaining pregnancy group (p<0.001). CONCLUSION: The initial serum B-hCG levels at 11 days after embryo transfer could be used to predict the pregnancy outcome in an IVF program. An initial progesterone level acquired on the 7th day after oocyte retrieval is not a useful indicator to predict pregnancy outcome.

Nine hips in eight patients had development of femoral endosteal cortical erosion after a cementless total hip arthroplasty. Serial anteroposterior and lateral radiographs of all of the affected femora were reviewed to determine the interval between the operation and the first recognition of the osteolytic lesion or lesion, as well as to evaluate the radiographic appearance and progression of the lesions. We reviewed the one hundred twenty hips in one hundred eleven patients had a cementless total hip arthroplsty at the department of Orthopaedic Surgery, Pusan National University Hospital from January 1985 to December 1991. The mean average follow up period was forty five months (twenty four to one hundred nine months). Osteolysis was first noted radiographically at forty four to eighty five months(mean, sixty three months) postoperatively; it occurred most frequently around the distal portion of the prosthetic stem. Three of the femoral components were shown to be loose. The remaining six hips had been judged to be stable when the endosteal erosion had first been identified. The osteolysis was more severe in the femora in which the component was loose than in those in which it was stable. Of the six stable hips and two unstable hips except revised one hip, who were followed, four hips had an increase in the size of osteolytic lesion with time. All two unstable hips and two stable hips among six stable hips had an increase in the size of osteolytic lesion with time. Therefore, close follow up in necessary for patients in whom osteolysis develops in association with a stable cementless femoral component.

Elderly patient with Genu Varus deformity is commonly treated by high tibial valgus osteotomy to unload the stress concentration medially. Most of these procedures were performed by closing wedge osteotomies and that revealed some problems. Most require a fairly large scar and later reoperation for implant removal. The Ilizarov apparatus and Ilizarov's principles of deformity correction seem to offer several advantages over other methods of high tibial osteotomy. With the Ilizarov method, distractional open wedge technique offers a biomechanically sound, predictably accurate, and reproducible method of correcting an extremity's mechanical axis deviation. From December 1991 to December 1993 at the department of orthopaedic surgery, Pusan National University Hospital, 5 patients(7 tibia) underwent the operation of correction of the genu varum using Ilizarov external fixator for osteoarthritis. The results were summarized as follows: l. All case were female, and the Mean age was 58 years old. 2. Preoperative mean varus angle were 20° and postoperative mean valgus angle were 6° at final follow-up. 3. The complication was not detected includes limb length descrepancy. 4. Mean Ilizarov external fixator fixation period was 5 months. 5. The results after average 1 year 1 month of follow-up were as follows: Excellent in 2 cases(29%), Good in 4 cases(57%), Fair in 1 case(14%), Poor in 0 case()%). 6. The early clinical and radiologic results were encouraging, although a longer follow-up period is necessary.

The face and notably the lips are important structures not only of aestheticvalue but also for expression, vibrancy and vitality. Sometimes we are encountered with the functional and aesthtetic lip problems especially in the patients with mandibular prognathism, such as excessive vermilion exposure, lip incompetence and hyperactivity of mentalis muscle. The etiologic factors are usually related to excessive anterior facial height, secondary to the abnormal development of perioral muscle, salivary gland and the swelling of lymphatic gland. Sometimes orthognathic surgery (mandibular setback osteotomy) alone is not accepted regarding to aesthetic value, there is likely to be a corresponding interest in adjunctive procedures such as genioplasty and soft tissue procedures. This article urges the incorporation of reduction cheiloplasty. It is a relatively minor procedure that can be easily reproducible and yields excellent, predictatable results with few complications. We treated two patients who have excessive vermilion exposure and marked abnormal lip eversion using reduction cheiloplasty combined with mandibular setback osteotomy, followed by improved facial harmony and patients were pleased.
