We compared the rate of continuous curvilinear capsulorhexis[CCC]con traction and degree of postoperative capsular fibrosis between patients with non-proliferative diabetic retinopathy and age-matched non-diabetic patients after phacoemulsification with posterior chamber acryl foldable intraocular lens implantation.Sixty-two eyes of 42 patients of non-proliferative diabetic retinopathy and 78 eyes of 55 patients of control group who underwent cataract surgery with acryl foldable intraocular lens were enrolled in this retrospective study.During follow up examination the rate of CCC contractions were evaluated by NIDEK EAS-1000 System and we measured the area of anterior capsular opening.The diabetic patients average percentage of anterior capsular shirinkage rate was higher than non-diabetic patient's. But no statistically significant difference was found between the two groups. In conclusion, small incision cataract surgery with acryl foldable intraocular lens implantation showed good results in diabetic patients.Further studies will be needed for better clinical safety and efficacy.

This study was performed to analyze the clinical, radiological results of 70 patients with isthmic spondylolisthesis and 30 patients with degenerative spondylolisthesis who were underwent with wide decompression, reduction with transpedicular screw system and posterolateral fusion from Mar. 1990 to Dec. 1995. In this study we excluded posterior lumbar interbody fusion, circumferential fusion or decompression method for sondylolisthesis. The mean follow up duration was 29 months. The most common level was L5-Sl in isthmic group (36 patients, 51%), and L4-5 in degenerative group (23 patients, 77%). The clinical result were analyzed according to Kirkaldy-Willis criteria. The satisfactory result were obtained 90% in each group. Screw failure occured in unstable level with severe slip angle, so anterior column support may be recommended in this group. Pedicle screw fixation and wide decompression augmented with posterolateral bone graft is a satisfactory alternative method for degenerative and isthmic spondylolisthesis.

BACKGROUND: The aim of study was to confirm the clinical effectiveness and results of wide and single anterior approach for fractures occurring along length of humerus. METHODS: A total of 23 patients with humeral fracture were enrolled into our study who were able to participate in at least one year of follow-up. Seven patients had segmental comminuted humeral fractures and 16 patients had distal humeral fractures. We made various tractions of the muscles to expose the proximal and the middle third humerus between the biceps and brachialis and the distal humerus by partial splitting of lateral side of biceps through a single incision. Postoperatively, we measured the Mayo elbow performance index (MEPI). RESULTS: we achieved bone union in all 23 patients. Solid union of the bone was achieved at an average 13.9 weeks. Postoperatively, two complications were observed screw loosening and nonunion. Revision surgery was performed in both patients. The patient with bone nonunion was treated using bone grafts. No postoperative infections or peripheral neuropathies were observed. At the final follow-up (average 20 months), we found that the average MEPI functional score of the patients was 91.7 points regardless of the fracture site. CONCLUSIONS: Our whole humerus with a single incision was effective for the treatment of segmental comminuted and distal fractures. we believe it is a useful alternative to preexisting methods of fracture fixation.

STUDY DESIGN: We retrospectively reviewed the cervical myelopathy patients who underwent anterior or posterior surgery. OBJECTIVES: This study was undertaken to analyze the preoperative radiologic evaluation and the results of the treatment of cervical myelopathy. SUMMARY OF LITERATURE REVIEW: The surgical treatment of cervical myelopathy consisted of anterior/posterior or combined surgery according to lesion site, symptoms, number of involved sequents or prevalence of the surgeon. Material and METHODS: We reviewed the clinical and radiological aspects of 28 patients Preoperative plain radiographs and MRI were evaluated with clinical symptoms. Postoperative clinical evaluation was performed according to the Robinson's criteria. RESULTS: On plain lateral radiographs, spinal canal diameter were 13.4+/-2.6/12.5+/- 1.7mm, Pavlovratios were 0.78+/-0.09/0.66+/-0.08, spondylosis indices were 1.70/1.80mm, and the antero-posterior compression ration of spinal cord were 42.4+/-8/44.0+/-6% for anterior surgery and posterior surgery group each. The results of 15 patients who received anterior decompression and interbody fusion were excellent in 11, good in 2, and fair in 2 cases. The results of 13 patients who underwent laminoplasty were excellent in 9, good in 3, and fair in one case. CONCLUSIONS: The patients who have Pavlov ratio less than 0.8 and spondylosis index more than 1.5mm on plain radiograph are vulnerable to developing myelopathy. It is better to do anterior decom pression and interbody fusion in patients who have one or two segments involved and kyphotic deformity of the cervical spine. Otherwise, patients who involve more than 3 segments and narrow spinal canal can be managed using laminoplasty posteriorly.

A ICL TM(STAAR Collamer Posterior chamber Implantable Contact Lens) lents ranging from -11D to -21.3D. And then we investigated the visualwas implanted in 12 eyes of 7 patients with preoperative spherical equivalents ranging from -11 D to -21.3 D. And then we investigated the visual acuity, mean endothelial cell loss, change of refractive error and postoperative complications.Average follow-up was 28.1 months. In the immediate postoperative days, all eyes had a significant increase in uncorrected visual acuity and the best corrected visual acuity was improved in 7 eyes(58.3%). Mean percent difference between preoperative and postoperative endothelial cell count was 3.22+/-0.05% . The mean preoperative spherical equivalent refraction was -15.65+/-2.78 D. At a mean follow-up of 1 month, mean spherical equivalent refraction was -1.67+/-0.72D, at a 6months, 12 months, 24 months, mean spherical equivalent refraction was each -1.56+/-0.72D, -1.63+/-0.68D, -1.73+/-0.76D. During follow-up days one eye developed an faint anterior subcapsular cataract but the patient remained symptom free. Other reported complication was transient increased intraocular pressure. Although the follow-up in our study was limited cases(12 eyes), from our experience, the posterior chamber implantable contact lens was efficacious and safe in the correction of high myopic refraction errors.

An isolated pyogenic pancreatic abscess (IPPA) without pancreatitis is extremely rare but can occur in patients with uncontrolled diabetes. This pathologic condition poses a clinical challenge in diagnosis and management because it can be confused easily with a malignancy. Endoscopic ultrasound (EUS) may be a useful diagnostic modality for indeterminate pancreatic lesions and IPPA. Here, we report two cases with elevated carbohydrate antigen 19-9 levels and pancreatic masses on cross sectional imaging. The patients were subsequently diagnosed with IPPA by EUS. EUS-guided drainage was performed successfully and the patients' clinical symptoms and radiologic findings improved. In our experience, EUS and EUS-guided drainage are crucial steps for the diagnosis and management of patients with an indeterminate pancreatic lesion. In addition, EUS-guided drainage has excellent technical and clinical outcomes for the treatment of IPPA.

Cervical pregnancy is a rare form of ectopic gestation in which the blastocyst implants in the cervical mucosa below the histologic cervical os. Because of the serious vaginal bleeding, hysterectomy was usually done in the management of cervical pregnancy. Howerver, conservative treatment is desirable for women who want to be pregnancy in the future. Methotrexate has been utilized recently for conservative management of cervical pregnancy. We report a case of cervical pregnancy which was treated succesfully with intramuscular methotrexate injection.

To evaluate the effect of capsular tension ring on prevention of capsular opening reduction induced by CCC in Phacoemulsification with silicone intraocular lens implantation, we prospectively studied 60 patients (60 eyes)who were operated from Sept, 1997 to Jun, 1998 at our hospital.All patients had standardized Phacoemulsification, continuous curvilinear capsulorhexis, and intraocular lens implantation performed by the same surgeon.Patients were randomized into two groups based on capsular tension ring insertion.We compared uncorrected visual acuity (UCVA), spherical equivalent (SE), astigmatism and the data obtained by the Anterior Eye Segment Analysis System (EAS-1000), anterior chamber depth, IOL tilting, decenteration, and anterior capsule opening area at 1 week and 1, 3, 6 months after surgery.Two groups showed a similar pattern of change of UCVA, SE and astigmatism. There are no statistical significances in comparison of anterior chamber depth and IOL decenteration in two groups, but IOL tilting of group II is greater than that of group I at 6 months after surgery.The mean anterior capsular opening area at 1, 3, 6 months postoperatively was smaller than that of 1 week in two groups, but no statistical significances were observed in group II (1, 3, 6 months, P = or > .05).The mean percentage reduction of group I was significantly smaller than that of group II at 3 and 6 months (P<.05)after surgery.Capsular tension ring might prevent a contraction of capsular opening and might enhance the stability of IOL.

STATEMENT OF PROBLEM: Implant screw loosening remains a problem in implant prosthodontics. Some abutment screws with treated surfaces were introduced to prevent screw loosening and to increase preload. DLC(Diamond Like Carbon) film has similar properties on hardness, wear resistance, chemical stability, biocompatibility as real diamond materials. PURPOSE: The purpose of this study was to investigate the effect of lubricant layer on abutment screw and to discriminate more effective method between soft lubricant and hard lubricant to prevent screw loosening. MATERIAL AND METHOD: In this study, 1mum thickness DLC was used as protective, lubricating layer of titanium screws and 3 times removal torque was measured on the abutment screws to investigate the difference in 10 coated and 10 non-coated abutment screws. RESULTS: The results indicated that the implants with DLC coating group were not more resistant to the applied force in screw loosening. At 32Ncm, the 3 times removal torque in DLC group were 27.7+/-2.89, 25.85+/-2.35 and 26.2+/-2.57. The removal torque in no-coated abutment screws were 27.85+/-4.23, 27.35+/-2.81 and 27.9+/-2.31, respectively. CONCLUSION: The lubricant layer used in this study was Diamond Like Carbon(DLC) and it have a properties of hard and stable layer. The DLC coating layer was hard enough to prevent distortion of screws in the repeated unscrewing procedure in clinical situation. The reduced friction coefficient in hard DLC layer was not effective to prevent screw loosening.
