OBJECTIVES: Recently, recombinant FSH (rFSH) has been manufactured using a Chinese hamster ovary cell line transfected with the gene encoding human FSH. Both rFSH and urinary gonadotropin (uFSH) could be used for controlled ovarian hyperstimulation (COH). However, uFSH implies a number of disadvantages, such as batch-to-batch inconsistency, no absolute source control, dependence on large amounts of urine, low specific activity, and low purity. The purpose of this study was to evaluate the efficacy of rFSH in human IVF-ET program. MATERIALS AND METHODS: A total of 508 infertile women was enrolled in this study. They are classified into rFSH group (n=177) or uFSH group (n=331), and all of them were matched by age and cause of infertility in same period. The Puregon(R) (Organon, Holland) was used as rFSH, and the Metrodin-HP(R) (Serono, Switzeland) and Humegon(R) (Organon, Holland) was used as uFSH. We subdivided the patients into three age groups. The outcomes of IVF-ET program were analyzed using the statistical package for social sciences (SPSS). RESULTS: There was no significant differences in the level of estradiol on hCG injection day, the numbers of retrieved oocytes, matured oocytes, fertilized oocytes, transferred embryos, frozen embryos between the two groups. The total dose (IU) of gonadotropin for COH was significantly lower in the rFSH group compared to uFSH group (1339+/-5491.1 vs 2527.8+/-1075.2 IU, p<0.001). Clinical pregnancy rate per embryo transfer in the rFSH group showed increasing tendency, compared to the uFSH group, but there was no statistical significance (35.2% vs 29.3%). Our results demonstrated that the relative efficiency of rFSH compared with uFSH is higher in older patients. CONCLUSIONS: The ovarian stimulatory effect and clinical outcome of recombinant FSH was similar to that of the urinary gonadotropin. The IVF-ET cycles with significantly lower dose of gonadotropin in rFSH group showed comparable results. Therefore, we suggest that recombinant FSH is more potent and effective than urinary gonadotropin.

Arthroscopic treatment of shoulder instability involves two techniques mainly, transglenoid suture technique and anterior anchoring system. However, anterior anchoring system has some disadvantages such as limited indication, high cost, technical difficulty and incapability to suture or reconstruct for all types of Bankart lesion. Disadvantages of transglenoid suture techniques are indirect suture tie, bump effect and possibility of the suprascapular nerve injury. The authors use modified transglenoid suture technique (Rhees method) for shoulder instability involving Bankart lesion, type II SLAP lesion and capsular laxity. The purpose of this study is to accurately describe the relationship between the major neurovascular structures and the pinning sites used in transglenoid suture technique (Rhees method). Placement of two or three arthroscopic Beath pinning sites was simulated in four fresh cadaveric shoulder specimens by placing Steinman pins into the glenoid rim under open field. The specimens were then dissected and the relationship of the pinning sites to the suprascapular nerve and suprascapular artery were recorded. In Bankart lesion repair, safe zone of pinning sites were 2 and 5 oclock in two portals in right shoulder, safe zone of pinning sites were 7 and 10 oclock in two portals in left shoulder. Safe direction of pinning was as possible as inferomedial side in scapula. In type II SLAP repair, safe zone of pinning sites were 2 oclock and just above 2 oclock of glenoid in right shoulder and 10 oclock and just above 10 oclock of glenoid in left shoulder. Safe direction of pinning was pararell to glenoid cavity and slightly superior in horizontal plane. From this study, these sites and directions appeared to be safe. Proper pinning depends on careful attention to the topographical anatomy about the shoulder.

This study was carried to determine the possibility of finding motile spermatozoa and fertilization, pregnancy rate after testicular sperm extraction(TESE) with ICSI in obstructive and non-obstructive azoospermic patients. In 154 cases(132 patients), obstructive azoospermia was 77 cases and non-obstructive azoospermia was 77 cases. In obstructive azoospermia, patients generally showed normal spermatogenesis and included vas agenesis(n=8), multiple vas obstruction(n=7), epididymal obstruction (n=54). Total of 982 retrieved oocytes were obtained and 84.4% were injected. The fertilization rates with 2 PN and cleavage rate were 72.5% and 62.3%, .respectively. 30 pregnancies(38.9%) were achieved and the ongoing pregnancies were 22 cases (28.6%). In non-obstructive azoospermia, patients showed hypospermatogenesis(n=49), maturation arrest(n=4), Sertoli cell only syndrome (n=24). The various stages of spermatogenic cell could be retrieved by TESE and could be reached normal fertilization and embryo development with ICSI. Total of 1072 retrieved oocytes obtained and 80.2% were injected. The fertilization rates with 2 PN and cleavage rate were 52.8% and 68.9%, respectively. 22 pregnancies(30.1%) were achieved and the ongoing pregnancies were 19 cases(26.0%). Conclusively, the combination of TESE with ICSI using testicular spermatozoa can achieve normal fertilization and pregnancy rate and effective method in obstructive and non-obstructive azoospermic patients.

Posttraumatic syringomyelia may result from a variety of inherent conditions and traumatic events, or from some combination of these. Many hypotheses have arisen to explain this complex disorder, but no consensus has emerged. A 28-year-old man presented with progressive lower extremity weakness, spasticity, and decreased sensation below the T4 dermatome five years after an initial trauma. Magnetic resonance imaging (MRI) revealed a large, multi-septate syrinx cavity extending from C5 to L1, with a retropulsed bony fragment of L2. We performed an L2 corpectomy, L1-L3 interbody fusion using a mesh cage and screw fixation, and a wide decompression and release of the ventral portion of the spinal cord with an operating microscope. The patient showed complete resolution of his neurological symptoms, including the bilateral leg weakness and dysesthesia. Postoperative MRI confirmed the collapse of the syrinx and restoration of subarachnoid cerebrospinal fluid (CSF) flow. These findings indicate a good correlation between syrinx collapse and symptomatic improvement. This case showed that syringomyelia may develop through obstruction of the subarachnoid CSF space by a bony fracture and kyphotic deformity. Ventral decompression of the obstructed subarachnoid space, with restoration of spinal alignment, effectively treated the spinal canal encroachment and post-traumatic syringomyelia.

PURPOSE: The purpose of this study was to introduce a method of using three-dimensional (3D) curved-multiplanar reconstruction (MPR) images for sylvian dissection during microsurgical treatment of middle cerebral artery (MCA) aneurysms. MATERIALS AND METHODS: Forty-nine patients who had undergone surgery for MCA aneurysms were enrolled. We obtained the 3D curved-MPR images along the sphenoid ridge using OsiriX MD™ imaging software, compared sylvian dissection time according to several 3D MPR image factors, and investigated the correlations between these images and intraoperative findings. RESULTS: Utilizing preoperative information of the sylvian fissure (SF) and peri-aneurysmal space on 3D curved-MPR images, we could predict the feasibility of sylvian dissection for a safe surgery. 3D curved-MPR images showed several features: first, perpendicular images to the sylvian surface in the same orientation as the surgeon's view; second, simultaneous visualization of the brain cortex, vessels, and cisternal space; and third, more accurate measurement of various parameters, such as depth of the MCA from the sylvian surface and the location and width of the SFs. CONCLUSION: In addition to conventional image studies, 3D curved-MPR images seem to provide useful information for Sylvian dissection in the microsurgical treatment of MCA aneurysms.

OBJECTIVE: The aim of this study was to accumulate the knowledge about medical abortion by assessment of the efficacy of medical abortion using methotrexate and misoprostol versus misoprostol in early pregnancy. METHODS: The 35 women at less than 56 days' gestation underwent medical abortion were reviewed prospectively. Seventeen women (group 1) underwent medical abortion using methotrexate with misoprostol and eighteen women (group 2) underwent using misoprostol alone. We measured percent change of serum beta-hCG, successful abortion, duration of vaginal bleeding, side effects. RESULTS: Overall success rate was 91.4%: success rate in group 1 was 100%, 84.2% in group 2. Vaginal bleeding lasted for a mean of 12 days (group 1), and 10 days (group 2). Percent change of serum beta-hCG level from day 1 to day 4 was 93.1 (group1), and -68.0 (group 2), that from day 1 to day 7 was -90.6 (group 1), and -97.6 (group 2). Side effects were minimal. CONCLUSION: No significant difference between group 1 (methotrexate and misoprostol) and group 2 (misoprostol alone) was found. Medical abortion is considered to be the therapy that is safe, and effective procedure in early pregnancy.

Verruca vulgaris is caused by human papillomavirus (HPV) infections. Verruca in the external auditory canal (EAC) has rarely been reported. A previous case report introduced surgical excision as a treatment for verruca in the EAC. We present a case of verruca vulgaris in both EACs that was successfully treated with an intralesional bleomycin injection. A 32-year-old male patient presented with ear fullness and palpable lumps in both EACs. Both of his canals were filled with multiple pinkish, papillomatous masses. Verruca vulgaris was confirmed by skin biopsy. An otolaryngologist referred this patient and recommended surgical excision. However, we performed intralesional bleomycin injections for treatment. Twice intralesional bleomycin injections at one-month intervals had excellent results without recurrence, ulceration or scar formation. This result indicates that bleomycin injections may prove to be an effective first-line treatment of verruca in the EAC.

Benign prostatic hyperplasia (BPH) is one of the most common diseases in older men and it may be accompanied with significant problems in the quality of life. Histological changes of BPH is starting at the age of 35, and there is induced in 60% of 60-year-old men, 80% of 80-year-old men, in 50% of the patient group may lead to lower urinary tract symptoms (LUTS). A 74-year-old man with huge BPH visited outpatient clinic with severe LUTS of an year duration. He was diagnosed with BPH 11 years ago and underwent transurethral resection of prostate twice. However, the prostate grew up to remarkable size again, which lead to the bladder outlet obstruction (BOO) and renal failure. There is no report for huge BPH (above 300 g) in Korea, we report a case with huge prostate size that is measured 330 g and treated with suprapubic open prostatectomy.
