Eosinophilia-myalgia syndrome(EMS) is a systemic illness that occurred as an epidemic by ingestion of over-the counter L-tryptophan preparation in the United States in October 1989. We report a Korean case of EMS not associated with the ingestion of either L-tryptophan or other nutritional supplements such as lysine and niacin.

Idiopathic atrophoderma of Pasini and Pierini(IAPP) is an uncommon condition of unknown etiology and typically affects persons in the second and third decades of life. IAPP consists of asymptomatic grey to brown depressed lesions with "cliff drop" borders, which are usually bilateral and located on the trunk. A 40-year-old woman visited our department because of unilateral atrophic lesions on the abdomen, right arm, and posterior aspect of right thigh for 20 years. Laboratory evaluations were normal and histologic examination revealed significantly decreased thickness in dermis. We report an unusual case of idiopathic atrophoderma of Pasini and Pierini presenting unilateral distribution.

Acetabular bone deficiencies encountered during the revision hip arthroplasties should be recon- structed to provide the implant stability and to restore the normal center of rotation of hip and the leg length. We revised the loosened acetabular cup by grafting fresh-frozen bulk femoral head and inserting uncemented cup in 17 hips of 15 patients. The average follow-up period was 2 years and 3 months. The acetabular bone deficiencies were type 2A in 6 hips, type 2B in 8, type 3A in 1 and type 3B in 2 by Paprosky's classification. Three blocks of femoral head were grafted in 3 type 3 deficiencies, but only one in type 2 deficiencies. The cup-host bone contact was 41% on the average. However, the cup-host bone contact in the zone I was present only in 12 out of 17 hips and its average was 14%. Incorporation of the allograft into the host bone occurred between 5 months and 1 year and 7 months (average, 8,6 months) after revision surgery. Significant radiographic loosening sign was noted only in 2 hips which had not only type 3B bone deficiencies reconstructed with 3 blocks of femoral head allograft but also no cup-host bone contact in zone I . The bulk allograft of fresh-frozen femoral head demonstrated acceptable results in type 2 acetabular bone deficiencies, although the follow-up period was relatively short. Reconstruction of type 3B acetabular bone deficiencies by using multiple blocks of femoral head allograft had been failed. We presumed that the lack of the graft stability and the intimate contact between the grafts and host bone was the cause of failure.

PURPOSE: The purpose of this study was to compare the accuracy of the implant master cast according to the type (pick-up, transfer) and the length (long, short) of the impression copings. MATERIALS AND METHODS: The metal master cast was fabricated with three internal connection type implant analogs (Osstem GS III analog), embedded parallel and with 10degrees of mesial angulation to the center analog. Four types of impression coping were prepared with different combinations of types (transfer, pick-up) and lengths (long, short) of the coping. The impressions were made using vinyl polysiloxane (one step, heavy + light body) with an individual tray, and 10 impressions were made for each group. Eventually, 40 experimental casts were produced. Then, the difference in the distance between the master cast and the experimental cast were measured, and the error rate was determined. The analysis of variance was performed using the SPSS (v 12.0) program (alpha = .05), and the statistical significance was set at P < .05. RESULTS: The ANOVA showed that the pick-up type impression coping exhibited a significantly lower error rate than the transfer type. However, no significant difference was observed with respect to the length of the impression coping. Additionally, no significant difference was observed between the parallel and mesial angulated groups. CONCLUSION: Within the limitations of this study, the pick-up type impression coping exhibited a more accurate implant master cast than the transfer type in parallel group. The accuracy of the implant master cast did not differ for different lengths of impression coping of at least 11 mm. Additionally, the accuracy of the implant cast was not different for the parallel and 10degrees mesial angulated groups.

PURPOSE: Some women choose to undergo posterior colporrhaphy (PC) concurrently with procedures for SUI to regain sexual confidence and improve sexual function. We determine the effect of PC on sexual function in women requiring a midurethral sling for SUI. MATERIALS AND METHODS: A total of 119 women were retrospectively reviewed 81 women had the midurethral sling alone (Group A), and 38 women voluntarily had PC concurrently with the midurethral sling (Group B). Sexual function was evaluated using the FSFI before and after surgery. RESULTS: The postoperative composite scores were significantly increased in both groups (Group A: p=0.02; Group B: p=0.04), and significant increases were observed in 'desire,' 'arousal' and 'satisfaction'. However, there were no significant differences in the composite score or six domainscores between the two groups. CONCLUSION: PC performed concurrently with midurethral sling for treatment of SUI does not provide any additional benefits towards improving the sexual function.

OBJECTIVE: The purpose of this study was to understand the differences in masseter muscle (MM) between the shifted and non-shifted sides in facial asymmetry patients, and the changes shown by MM after mandibular surgery. METHODS: Pre- and post-operative CT scans were performed on 12 Class III patients with facial asymmetry who were treated by intraoral vertical ramus osteotomy and 10 subjects with normal occlusion. Using the V-works 4.0 program (Cybermed, Seoul, Korea), 3-dimensional images of the mandible, and MM were reconstructed, and evaluated. RESULTS: In the asymmetry group, the MM angle between the shifted and non-shifted sides was only significantly different (p < 0.05). Compared with normal occlusion, the asymmetry group showed a significantly smaller volume and maximum cross-sectional area in both sides of MM (p < 0.05). After mandibular surgery, the angle of MM (p < 0.01) and differences in angle between the shifted and non-shifted sides of MM (p < 0.05) were significantly decreased. The thickness in the maximum cross-sectional area was significantly increased (p < 0.01). After surgery, MM in facial asymmetry patients was similarly changed to those in the normal occlusion group except for widths. CONCLUSIONS: MM in facial asymmetry was definitely different from those in normal occlusion. However, this study suggests that MM changed symmetrically in conjunction with the mandible after proper mandibular surgery.

Maspin is a recently described gene with tumor suppressor activity. The gene product is a 42 kD protein with homology to the serpin family of protease inhibitors and may play a role as an inhibitor of tumor cell invasion. The prior observation that invasive breast cancers and their metastases showed decreased maspin protein expression by immunostaining supports this speculation. However, the role of maspin in breast cancer progression has not been studied in detail. We, therefore, studied maspin protein expression in a series of hyperplasia, atypical ductal hyperplasia, intraductal carcinoma and invasive carcinomas. Immunohistochemical staining (IHC) for maspin was performed on paraffin sections of 136 breast specimens using a commercially available monoclonal antibody. Among the 106 cases studied were 36 moderate/florid ductal hyperplasia, 11 atypical ductal hyperplasia (ADH), 29 intraductal carcinoma (IDC) (4 low grade, 13 intermediate grade, 12 high grade) and 30 invasive ductal carcinomas. Thirty cases of normal breast were also studied as control group. IHC stains were scored using a semiquantitative scoring system. The mean IHC scores for maspin for normal, moderate/florid hyperplasia, atypical ductal hyperplasia, intraductal carcinoma, and invasive carcinoma were 5.51 1.30, 7.36 0.72, 3.82 1.60, 4.48 2.69, 3.97 3.30, respectively. These scores for each category were statistically significant (p<0.05), except between ADH and IDC. Maspin protein expression was increased in most cases of moderate/florid hyperplasia, while maspin expression was more heterogeneous in ADH and IDC. In high grade IDC, maspin protein expression was stronger than low and intermediate grade IDC, and this suggests the possibility of a compensatory cellular response against the forces driving further tumor progression. Two thirds of invasive ductal carcinomas expressed maspin protein weakly and focally. All metastatic carcinomas of lymph nodes were negative for maspin. It is possible that high grade IDC with strong maspin expression may represent a subset less likely to progress to invasive cancer. This speculation merits investigation in clinical outcome studies.

Following diabetic retinopathy, retinal vein occulusion is probably the most common retinal vascular disorder. Author studied 47 cases of occlusion of the retinal vein in aspects of sex, age, laterality, change of visual acity, associated diseases and location of the affected vein. The results were as follows; 1. There was no significant difference in mobidity rate of retinal vein occlusion between male and female or right and left. 2.73% of BRVO affected superior temporal branch of retinal vein. 3. The incidence of BRVO is 2.2 times of that of CRVO. 4. The visual acuities of initial visit were below 0.1 in 73% of CRVO and 46% of BRVO. 5. 40% of CRVO retained or regained vision of 0.1 or better. 6. The most common associated disease was systemic hypertension.

Organoids show great potential in clinical translational research owing to their intriguing properties to represent a near physiological model for native tissues. However, the dependency of organoid generation on the use of poorly defined matrices has hampered their clinical application. Current organoid culture systems mostly reply on biochemical signals provided by medium compositions and cell-cell interactions to control growth. Recent studies have highlighted the importance of the extracellular matrix (ECM) composition, cell-ECM interactions, and mechanical signals for organoid expansion and differentiation. Thus, several hydrogel systems prepared using natural or synthetic-based materials have been designed to recreate the stem cell niche in vitro, providing biochemical, biophysical, and mechanical signals. In this review, we discuss how recapitulating multiple aspects of the tissue-specific environment through designing and applying matrices could contribute to accelerating the translation of organoid technology from the laboratory to therapeutic and pharmaceutical applications.
