This article reports a case of spontaneous ovarian hyperstimulation syndrome (OHSS) following a thawed embryo transfer cycle. OHSS, a potentially life-threatening condition, is an iatrogenic complication of controlled ovarian stimulation; therefore, it is very important to prevent and treat OHSS during treatment with ovulation-inducing agents. Despite our efforts to prevent OHSS, in this case, severe spontaneous OHSS occurred, which resulted in uncontrolled preterm labor and a preterm delivery and also persisted for 6 weeks after delivery. Freezing all embryos cannot entirely prevent the development of OHSS because OHSS can occur spontaneously. Although spontaneous OHSS remains a rare event, females with a history of OHSS may have an elevated risk for spontaneous OHSS. We suggest closely monitoring cases of pregnancy following thawed embryo transfer for early diagnosis of spontaneous OHSS and the use of conservative management.

OBJECTIVE: To evaluate the accuracy of combined transvaginal ultrasound and beta-hCG discriminatory zone for diagnosing intrauterine pregnancy, abortion, and ectopic pregnancy in early abnormal pregnancy. METHODS: Initial ultrasound findings and beta-hCG level were compared with final pregnancy outcome in 164 early pregnant women who visit our hospital with vaginal bleeding or abdominal pain. The sensitivity, specificity, and predictive value by the combination of two diagnostic tools were calculated. Statistic analysis of collected data used x2 of SPSS(9.0). RESULTS: Of 90 women with normal outcome, 64(71.1%) had a gestational sac 5mm, and in 47 cases, the hCG level was above 1,800 mIU/ml. Transvaginal ultrasound was non-diagnostic in 47(28.6%) of 164 women, and especially, 43(53.1%) of 81 cases with beta-hCG levels below 1,800 mIU/ml. The portion of accurate ultrasound diagnosis was significantly higher in women above 1,800 mIU/ml (85.5%, 71 of 83 cases) compard with levels below 1,800 mIU/ml (37.0%, 30 of 81 cases) : P < 0.001; Relative Risk(RR) 2.31; CI 95%. Sensitivity of transvaginal ultrasound diagnosis of intrauterine pregnancy, abortion, and ectopic pregnancy was 90.2%, 79.3%, and 66.7% in women who presented with beta-hCG levels above 1,800 mIU/ml, and 41.0%, 23.5%, and 75% below 1,800 mIU/ml, respectively. And, negative predictive value was 83.9%, 89.7%, and 98.8% in each of intrauterine pregnancy, abortion, and ectopic pregnancy above 1,800 mIU/ml, and 64.6%, 60%, and 97.3% below 1,800 mIU/ml, respectively. CONCLUSIONS: The sensitivity, specificity, and predictive value of transvaginal ultrasound for diagnosing abnormal early pregnancy were poor except cases of ectopic pregnancy when beta-hCG levels were low than discriminatory zone. Ultrasound impressions were well related with beta-hCG levels.

PURPOSE: Long-term follow-up results of concurrent bilateral or unilateral cementless hip arthroplasty were compared. MATERIALS AND METHODS: Forty eight and 49 patients with concurrent bilateral and unilateral hip artrhoplasties who had more than a 17-year follow-up time were selected. At final follow-up, mean ages were 69.1 and 66.7 years old in the bilateral and unilateral groups, respectively. Mean follow-up times were 21.5 and 22.4 years in the bilateral and unilateral groups, respectively. Clinical results were attained using Harris hip score and standardized anteroposterior and lateral view X-rays. RESULTS: The bilateral group had mean Harris scores of 44.3(standard deviation 3.78) preoperatively, and 81.2 (10.75) at final follow-up. For the unilateral group, the mean scores were 46.5(3.27) preoperatively, and 80.1 (12.05) at final follow-up. At final follow-up, an acetabular cup was securely located in 78.9% and 82.8% of the bilateral and unilateral groups, respectively, and all cases showed firm fixation of the femoral stem in both groups. Osteolysis around the cup and stem were found in 26.3% and 31.4% of the bilateral group and 16.6% and 17.1% of the unilateral group, respectively. Polyethylene wear rate was 0.17 mm/yr and 0.16 mm/yr in the unilateral and bilateral groups, respectively. Using the Kaplan-Meier method, 17-year survival rates for cup and stem were 78% and 89% in the bilateral group, respectively, and 78% and 86% in the unilateral group, respectively. CONCLUSION: In 17-year long-term follow-up, concurrent bilateral hip arthroplasty was insignificantly different clinically and radiologically from the result of unilateral hip arthroplasty.

PURPOSE: To compare the two methods of decompression using a microscope with a tubular retractor system and open microscopic decompression in lumbar spinal stenosis. MATERIALS AND METHODS: The records of patients that had undergone decompression from May 2000 to April 2005 were reviewed. The average follow-up period was 29 months (4~60 months). The duration of hospital stay, estimated blood loss, relief of pain, and operating time were reviewed retrospectively. Analysis was conducted by telephone interview and chart review (McNab's criteria). Pre- and post-operative Visual Analogue Scale (VAS) scores and JOA scores were also evaluated. RESULTS: Of the total 53 patients, open microscopic decompression was performed on 27 patients, and 26 patients received surgery using microscopic decompression with tubular retractors. There were no patients who had serious complications such as infection or nerve root injury in either of the groups. The average estimated blood loss was 205 cc for the open microscopic decompression group versus 120 cc in the minimally invasive microscopic decompression (MIMD) group (p=0.019). The mean operating time was 2.5 hours in the open microscopic decompression group and 2.2 hours in the MIMD group (p=0.048). As shown by the clinical results, good or excellent results were shown by the McNab's criteria after operation, 85.1% for the open microscopic decompression group and 94.7% for the MIMD group, respectively. The JOA score improved after surgery, with average scores of 14.5 to 24.5 in the open microscopic decompression group, and 15.9 to 25.6 in the MIMD group. The VAS score was reduced after surgery, with an average score of 8.0 to 3.7 in the open microscopic decompression group, and 8.3 to 2.6 in the MIMD group. CONCLUSION: In terms of blood loss, the MIMD group showed significantly better results than the open microscopic decompression group. The clinical results showed no statistically significant difference between the two groups.

PURPOSE: The purpose of the study is to compare the outcomes between three different one-layer vasovasostomy techniques: original one-layer, modified one-layer, and V-V type one-layer microsurgical vasovasostomy. MATERIALS AND METHODS: We retrospectively reviewed the charts and surgical records of all surgical procedures performed on a series of 117 consecutive patients undergoing a microsurgical one-layer, modified one-layer or V-V type one-layer vasovasostomy between May 1995 and March 2000. An original one-layer vasovasostomy was used in 48 men (group 1), a modified one-layer vasovasostomy in 35 men (group 2), and V-V type one-layer vasovasostomy in 34 men (group 3). A successful outcome (patency) was defined as sperm presenting at the follow-ups. RESULTS: The sperm concentration (million/ml) and motility (%) were as follows: in original one-layer vasovasostomy 17.5 and 32.9, in modified one-layer vasovasostomy 26.1 and 28.5 and in V-V type vasovasostomy 30.5 and 32.3. There were no significant differences in patency (85.4%, 91.4% and 91.2%) and pregnancy rate (56%, 62.5% and 63.6%) of the procedures. If the obstructive interval had been less than 4 years, patency was 87.5% and pregnancy rate was 61.5%, 5 to 9 years 95.8% and 63.4% and 10 years or more 83% and 58.3%. There were no correlations between obstructive interval and rates of patency and pregnancy. CONCLUSIONS: The patency and pregnancy rate revealed slightly better result in modified one-layer or V-V type one-layer microsurgical vasovasostomy than in original one-layer microsurgical vasovasostomy. However, they had statistically no significant differences in overall.

PURPOSE: The olecranon osteotomy in intra-articular comminuted distal humerus fractures is a suggested technique for excellent exposure of articular fractures. However, complications including delayed union, nonunion of osteotomy site have been reported. Authors have applied predrilling for cannulated screw before osteotomy for achievement of rapid and accurate reposition of separation part and added wire fixation for secure stability. The purpose of this study is to evaluate the efficacy of this fixation procedure following the olecranon osteotomy during the internal fixation of intra-articular fracture of the distal humerus. MATERIALS AND METHODS: This study retrospectively analyzed 14 cases (9 women and 5 men) of intra-articular distal humerus fractures in which the olecranon osteotomy was applied. The mean age of patients was 53.4 years (range, 25 to 83 years), and the average follow-up period was 15.9 months. Eleven cases were classified as AO 13-C3, and the other 3 cases were AO 13-C2. Reduction accuracy, union period of osteotomy site on follow-up radiographs and postoperative complications related to olecranon osteotomy were evaluated. RESULTS: All osteotomized parts showed no position change and solid union with normal alignment at the last follow-up. The mean period of bony union was 3.5 months (range, 2 to 5 months). There were no complications related to olecranon osteotomy except one case of non-displaced fracture of the proximal ulnar shaft at the level of cannulated screw tip caused by forceful passive physical therapy. It was managed by conservative treatment without further problem. CONCLUSION: Predrilled cannulated screw and wire fixation following the olecranon osteotomy during internal fixation of intra-articular comminuted distal humerus fractures showed satisfactory results in the union of osteotomy site and it could be a recommendable procedure when fractures require olecranon osteotomy.
