Authors have reviewed a series of 41 cases of fibrous dysplasia which were treated surgically at the Department of Orthopedic Surgery, College of Medicine, Seoul National University. After mean follow-up of 25 months, we summarized the results as follows; 1. Among the 41 patients, 20 were male patients(M:F= 1:1.05). The average age was 20.2 years old. It was the most common in the 2nd decade(44%). The most common site was femur (53.6%) followed by tibia (28.6%) in monostotic type. Each polyototic patient had 3.8 locations in average. 2. The results were better in skeletally mature patients (86%) than in immature patients (42%). 3. Satisfactory results seemed to be expected in monostotic type (71%) than polyostotic type(33 %) 4. Satisfactory results seemed to be expected in sclerotic type(78%) than cystic type(50%) or ground glass appearance type (62%). 5. Autograft(71%) was superior to xenograft(40%) in our study. However, xenograft only or xenograft with autograft can be a recommendable method of treatment for a very large lesion or for a patient with insufficient graft donor site.

The purpose of this study is to develop species-specific DNA probes and polymerase chain reaction (PCR) primers for detection and identification of Prevotella nigrescens (P. nigrescens) 9336. This study procedure includes (1) whole-genomic DNA extraction of P. nigrescens 9336 (2) construction of the genomic DNA library, (3) screening of strain-specific DNA probe by reverse dot Hybridization method, (4) confirmation of strain-specific DNA probe by Southern blot analysis, (5) determination of nucleotide sequences of strain-specific DNA probe. Thirty-five restriction fragments of P. nigrescens 9336 genomic DNA digested with the Hind III were obtained. Reverse dot hybridization and Southern blot analysis data showed that three of them, Pn10, Pn23, and Pn35, could be P. nigrescens 9336-specific DNA probes. These data indicated that these DNA probes could be useful in detection and identification of the P. nigrescens 9336.

Parovarian cysts constitute 10% of adnexal masses. They were found in broad ligament and mostly arise from mesothelium and less commonly from paramesonephric element and rarely from mesonephric element. In most cases parovarian cysts were asymptomatic. So, they were found incidentally at surgery for other conditions. Torsion is infrequent and it is difficult to distinguish it from torsion of other adnexal masses, appendicitis, etc. Recently, we experienced a voluminous parovarian cyst undergoing torsion, 25 cm in diameter. The case is presented with a review of literature.

Abdominal pregnancy is a rare form of extrauterine pregnancy which is account for 1.4% of all ectopic pregnancy cases. Among these omental pregnancy is extremely rare and may cause life-threatening massive hemorrhage as a complication. But the diagnosis of early abdominal pregnancy is difficult because of non specific findings about clinical history, physical examination and ultrasonography. Risk factors related to ectopic pregnancy include inflammation, infection and surgery, but endometriosis is an uncommon factor. We present a case of the ruptured primary omental pregnancy associated with endometriosis with a review of the literature.

BACKGROUND: Stellate ganglion block (SGB) is the most common nerve block procedure in pain clinics. To evaluate changes in the hemodynamics and peripheral blood flow on the affected extremity after SGB, SGB was performed unilaterally one at a time on the right and left stellate ganglions by injecting 1% mepivacaine 10 ml without epinephrine in a designated healthy man. METHODS: SGB was repeated 16 times in one subject (right side SGB: 8, left side SGB: 8) by the same clinician. The mean arterial pressure (MAP), heart rate (HR), cardiac index (CI), systemic vascular resistance index (SVRI) and peripheral blood flow were measured in the supine position before (control), and 3, 6, 9, 12, and 15 minutes after SGB using thoracic electrical bioimpedence (Bioz system A-10043, Cardiodynamics, USA), sphygomanometer, and flow meter. RESULTS: The values after SGB including MAP, HR, CI, and SVRI increased slightly compared to the control value. However, peripheral blood flow increased significantly (p < 0.05). The SGB did not affect systematic hemodynamics and the comparison between left and right SGB in hemodynamic changes were not clinically significant. Following SGB, ptosis (100%), nasal stiffness (100%), skin temperature elevation (100%), hoarseness (100%), numbness (81%), dizziness (25%), and swallowing difficulty (25%) were observed. CONCLUSIONS: We concluded that SGB showed to be a hemodynamically safe clinical technique.

STUDY DESIGN: A cross-sectional, case-control study. PURPOSE: To investigate associations between physical fitness measures and disabilities related to back pain and quality of life (QOL) by the presence of symptomatic lumbar spinal stenosis (LSS) in elderly Korean women. OVERVIEW OF LITERATURE: LSS leads to decreased functioning and reduced QOL. However, correlations among physical fitness, disability, and QOL have not been investigated in elderly women with LSS. METHODS: Participants included women aged 65 years and older (n=192), divided into a study group (n=38) and a control group (n=154) based on the presence/absence of LSS. All participants underwent physical function and fitness tests. Oswestry disability index (ODI) scores and EuroQol five-dimensional questionnaire (EQ-5D-5L) scores were used to assess disability and health-related QOL. RESULTS: The results for the handgrip strength, sit-and-reach, functional reach, and timed up and go (TUG) tests were significantly higher in the control group than the LSS group. ODI scores were significantly higher and EQ-5D-5L scores significantly lower in the LSS group. TUG and functional reach test scores were significantly correlated with ODI scores, and handgrip strength was strongly interrelated with ODI and EQ-5D-5L scores in the LSS group. No other physical fitness measures showed statistically significant relationships with ODI or EQ-5D-5L scores. CONCLUSIONS: In elderly Korean women with LSS, back pain-related disability and QOL are significantly associated with some physical fitness parameters such as handgrip strength. Handgrip strength reflects general muscle strength, which is significantly interrelated with the level of disability and QOL. Our results suggest that enhancing generalized muscle strength helps to reduce disability due to back pain and improve QOL in patients with LSS.

BACKGROUND AND OBJECTIVES: Storage mites, Tyrophagus putrescentiae (TP) and Acarus siro (AS), known as the major causative allergens to people who deal with stored foods and grains, may occur more frequently in house dust than expected. During the recent 6 months, positive reactions to TP and AS were observed as frequently as those to Dermatophagoides pteronyssinus (DP) in patients with allergic rhinitis in Pusan. The purpose of this study was to identify allergenic components within TP and AS, and evaluate the cross reactivity with DP. MATERIALS AND METHODS: Using extracts of DP, TP and AS, prepared after dialysis and lyophilization, allergenic components were identified using SDS-PAGE and western blotting. Cross reactivity among them were evaluated by inhibition tests using pharmacia CAP system. RESULTS: The protein components of DP, TP and AS, showed different patterns in SDS-PAGE. Molecular weight of major IgE binding components of TP were 17 kD, 25 kD and 67 kD, and those of AS were 18 kD, 19 kD, 25 kD and 27 kD. TP- or AS-specific IgE was partially inhibited by DP extract; however, DP-specific IgE was not significantly inhibited either by TP or AS extract. Significant inhibition were noted between TP and AS. CONCLUSION: TP and AS may share common allergens with DP. However, sensitization to TP or AS was also suspected in some cases. The percentage of Acaridae family in Pusan was 12% of total mites. Therefore, storage mites should be considered as causative allergens and included in allergy test battery.

STUDY DESIGN: Retrospective fusion level(s)-, age-, and gender-matched analysis. PURPOSE: To determine whether the application of a topical gelatin-thrombin matrix sealant (Floseal) at the end of anterior cervical discectomy and fusion (ACDF) can reduce the amount of postoperative hemorrhage. OVERVIEW OF LITERATURE: The effect of the matrix sealant in decreasing postoperative hemorrhage following ACDF has not been reported. METHODS: Matrix sealant was (n=116, study group) or was not applied (n=58, control group) at the end of ACDF. Patients were selected by 1:2 matching criteria of fusion level(s), age, and gender. Seven parameters described below were compared between the two groups. RESULTS: The total drain amount for the first 24 hours (8+/-9 versus 27+/-22 mL), total drain amount until the 8-hour drainage decreased to < or =10 mL (8+/-10 versus 33+/-26 mL), and the total drain amount until 6 AM on the first postoperative day (7+/-8 versus 24+/-20 mL) were significantly lower in the study group than the control group (all p<0.001). The time for the 8-hour drainage to decrease to < or =10 mL was significantly lower in the study group (10+/-5 versus 26+/-14 hours, p<0.001). The 8-hour drainage decreased to < or =10 mL on the operation day in most patients (88%) in the study group versus mostly on the first (48%) or second (33%) postoperative day in the control group (p<0.001). The total drain amount until 6 AM on the first postoperative day was 0 mL in 43% of patients in the study group and in 7% in the control group (p<0.001). No patient in either group required hematoma evacuation. CONCLUSIONS: Application of the topical matrix sealant at the end of ACDF can significantly reduce the amount of postoperative hemorrhage.

We aimed to evaluate the current nationwide trend, efficacy, safety, and quality of life (QoL) profiles of hormone treatment in real-world practice settings for prostate cancer (PCa) patients in Korea. A total of 292 men with any biopsy-proven PCa (TanyNanyMany) from 12 institutions in Korea were included in this multi-institutional, observational study of prospectively collected data. All luteinizing hormone-releasing hormone (LHRH) agonists were allowed to be investigational drugs. Efficacy was defined as (1) the rate of castration (serum testosterone ≤50 ng dl^-1) at 4-week visit and (2) breakthrough (serum testosterone >50 ng dl^-1 after castration). Safety assessments included routine examinations for potential adverse events, laboratory tests, blood pressure, body weight, and bone mineral density (BMD, at baseline and at the last follow-up visit). QoL was assessed using the Expanded Prostate Cancer Index Composite-26 (EPIC-26). The most common initial therapeutic regimen was LHRH agonist with anti-androgen (78.0%), and the most commonly used LHRH agonist for combination and monotherapy was leuprolide (64.0% for combination and 58.0% for monotherapy). The castration and breakthrough rates were 78.4% and 6.6%, respectively. The laboratory results related to dyslipidemia worsened after 4 weeks of hormone treatment. In addition, the mean BMD T-score was significantly lower at the last follow-up (mean: -1.950) compared to baseline (mean: -0.195). The mean total EPIC-26 score decreased from 84.8 (standard deviation [s.d.]: 12.2) to 78.3 (s.d.: 8.1), with significant deterioration only in the urinary domain (mean: 23.5 at baseline and 21.9 at the 4-week visit). These findings demonstrate the nationwide trend of current practice settings in hormone treatment for PCa in Korea.
