Multifocal choroiditis and panuveitis(MCP) is a clinical syndrome characterized by vitritis, and punched-out fundus lesions mimicking presumed ocular histoplasmosis. We diagnosed MCP in a twenty-eight years old woman with the complaint of decreased vision and floater symptom. Retinochoroidal anastomosis via one of retinochoroidal scars was noted in this case. The patient was treated with oral and periocular steroid and ws observed for 11 months during which choroidal neovascularization and macular edema ws not developed. We present this case because, as far as our knowledge goes, There has been no reported case of MCP with retinochoroidal anastomosis.

Although many methods have been developed to correct the aging process of the head and neck, the correction of nasolabial folds still remains a difficult area. The difficulty of correcting nasolabial fold is due to the anatomical location and the difference of aging process. From March 2000 to February 2001, the authors operated on 10 aging face patients using face lift with SMAS and FAME(Finger-assisted malar fat pad elevation) technique. The authors repositioned the SMAS-platysma flap posterosuperiorly and used finger dissection of the malar fat pad enabling a 3-dimensional correction and repositioning of the fat pad without detachment of the zygomatic ligament. The finger dissection of the malar fat pad attached to the skin enables a more anatomical correction of the malar fat pad with a more natural looking layer and longer lasting results in addition to decreased hematoma, edema and postoperative pain compared to previous methods.

PURPOSE: The purpose of this study was to evaluate the usefulness of MR imaging of pathologic fractures of the long bones. MATERIALS AND METHODS: In 18 patients aged between four and 75 (mean, 25.8) years with histologically confirmed pathologic fractures of the long bones, plain radiographs and MR images were retrospectively analyzed. The former were examined with regard to location and type of fracture, and the presence or absence of underlying disease causing fracture; and the latter in terms of underlying disease, extraosseous mass formation, and soft tissue change. RESULTS: The long bones involved were the femur in nine patients, the humerus in six, and the tibia in three. Underlying diseases were metastatic tumor (n=6), benign bone tumor (n=5), primary malignant bone tumor (n=4), osteomyelitis (n=2), and eosinophilic granuloma (n=1). Plain radiographs showed the fracture site as the metaphysis in ten cases, the diaphysis in five, and the metadiaphysis in one. Fractures were either transverse (n=10), oblique (n=3), spiral (n=1), vertical (n=1), or telescopic (n=1). In two cases, the fracture line was not visible. MR images revealed underlying diseases in all cases. A solid mass was present in all cases of malignant bone tumor, and an extraosseous mass in five such cases. Two benign bone tumors took the form of a cystic mass, two were a cystic mass containing an enhanced solid portion, and one was a solid mass. A soft tissue hematoma was seen in three cases. CONCLUSION: Where pathologic fracture of a long bone had occurred, or a pathologic fracture in which the findings of plain radiography were equivocal, MR imaging was useful for evaluating the pattern and extent of an underlying lesion.

PURPOSE: To investigate changes in the ovary revealed by MR imaging before and after radiotherapy in premenopausal patients with cervical carcinoma. MATERIALS AND METHODS: Thirty-three premenopausal patients with cervical carcinoma underwent radiation therapy at an average dosage of 11,279 (external: 5,352; internal: 5,927) cGy. Before and after this therapy, all underwent pelvic MR imaging using a 1.5T MR scanner (GE Medical Systems, Milwaukee, U.S.A.). The average interval of follow-up MR imaging was 7.2 months, and axial T1-weighted and axial and sagittal T2-weighted MR images were obtained. The presence, size number of follicles, and differentiation of the zonal anatomy of the ovary were determined by two radiologists, who reached a consensus. RESULTS: After radiation therapy, all patients ceased menstruation. For ovaries, the detection rates before and after radiation therapy were 94% (62/66) and 39% (26/66) (p<0.05), respectively, and average ovary size was 2.6x1.9x2.2 cm before and 1.7x1.3x1.4 cm after therapy (p<0.05). The average number of ovarian follicles before and after therapy was 5.1 and 3.1, respectively (p<0.05). T2-weighted imaging, demonstrated differentiation of zonal anatomy in 74% of cases (46/62) before radiotheraphy, and 15% (4/26) after (p<0.05). CONCLUSION: Our study has shown that after radiation therapy in premenopausal patients with cervical cancer, detection rates, average size, and the number of ovaries decreased, findings which are similar to those for normal postmenopausal ovary. MR imaging can reveal structural change in ovaries.

PURPOSE: In this study, the medication effects of Milnacipran and Pregabalin, as well known as fibromyalgia treatment medicine, in fibromyalgia syndrome patients were compared through the change of BOLD signal in pain related functional MRI. MATERIALS AND METHODS: Twenty fibromyalgia syndrome patients were enrolled in this study and they were separated into two groups according to the treatment medicine: 10 Milnacipran (MLN) treatment group and 7 Pregabalin (PGB) treatment group. For accurate diagnosis, all patients underwent several clinical tests. Pre-treated and post-treated fMRI image with block-designed pressure-pain stimulation for each group were obtained to conduct the statistical analysis of paired t-test and two sample t-test. All statistical significant level was less than 0.05. RESULTS: In clinical tests, the clinical scores of the two groups were not significantly different at pre-treatment stage. But, PGB treatment group had lower Widespread Pain Index (WPI) and Brief Fatigue Inventory (BFI) score than those of MLN treatment group at post-treatment stage. In functional image analysis, BOLD signal of PGB treatment group was higher BOLD signal at several regions including anterior cingulate and insula than MLN treatment group at post-treatment stage. Also, paired t-test values of the BOLD signal in MLN group decreased in several regions including insula and thalamus as known as 'pain network'. In contrast, size and number of regions in which the BOLD signal decreased in PGB treatment group were smaller than those of MLN treatment group. CONCLUSION: This study showed that MLN group and PGB group have different medication effects. It is not surprising that MLN and PGB have not the same therapeutic effects since these two drugs have different medicinal mechanisms such as antidepressants and anti-seizure medication, respectively, and different detailed target of fibromyalgia syndrome treatment. Therefore, it is difficult to say which medicine will work better in this study.

To simulate the posterior vitreous detachment (PVD) in the rabbit, 1 IU hyaluronidase and/or 0.2 ml of perfluoropropane gas was intravitreally injected. Ophthalmoscopic, light microscopic examination prepared by cryotechnique, electron microscopic examination, and electroretinogram were done on the 3rd and 28th postoperative days. As a result, the eyes undergone simultaneous intravitreal injection of 1 IU hyaluronidase and 0.2 ml perfluoropropane gas showed membranous structure split from the internal limiting membrane of the superior retina in 3 days after injection. The eyes also demonstrated membranous structure separated from the superior retina after 28 days, simulating vitreous detachment. On the contrary, neither agent alone induced vitreous detachment. No toxic retinal changes associated with simultaneous intravitreal injection of 1 IU hyaluronidase and 0.2 ml perfluoropropane gas were observed. Therefore, with a future support by histologic examination other than cryotechnique and by immunohistochemical analysis, the simultaneous intravitreal injection of perfluoropropane gas and hyaluronidase would be a promising method to induce vitreous detachment in non-vitrectomized eye.
