PURPOSE: To report a case of inflammatory granuloma in the right medial canthal area which occurred seven years after a cosmetic collagen-containing dermal filler injection in the forehead. CASE SUMMARY: A-47-year-old female, who had been treated with collagen-containing filler 7 years earlier, presented with a mass in the right medial canthal area discovered 20 days previously. There was mild tenderness and the mass was firm and not fixed. The patient reported that the size of the mass was slowly increasing. Orbital computed tomography and magnetic resonance imaging showed an approximate 1 cm-sized, poorly defined, enhancing nodular thickening without evidence of bony erosion. The mass was removed through a skin incision and unidentified foreign bodies were found around the mass. On histopathologic examination, it was diagnosed as inflammatory granuloma caused by foreign substances. CONCLUSIONS: Collagen-containing fillers are widely used in cosmetic surgery for their lasting effect and few complications. However some complications such as inflammatory granuloma may occur at the injection site or other sites, even several years after operation.

PURPOSE: To report the results of managing dislocated posterior chamber intraocular lenses (PC IOLs) by externalizing both haptics alternately through a single clear corneal incision. METHODS: The study included 10 eyes of 10 patients in which a dislocated PC IOL was managed with pars plana vitrectomy. With our modified method, both haptics were alternately externalized through a single clear corneal incision for suture knot placement and then reinserted. RESULTS: The dislocated PC IOLs were repositioned successfully in all 10 eyes, and the corrected visual acuity improved postoperatively in 9 eyes at a minimum follow-up of six months. Abnormal IOL position, IOL capture by the iris, or posterior synechia was not observed. Hypotony maculopathy occurred in one eye, but the macular folding disappeared and the visual acuity improved after adding one-bite suture. CONCLUSIONS: The technique we describe in this study is a simple and effective procedure for repositioning posteriorly dislocated PC IOLs with minimal intraocular manipulations and complications.

PURPOSE: To obtain the average values of anterior segment structures of adult Koreans using Visante OCT in relation to age and sex, and to compare the central corneal thickness values with these measurements using an A-scan ultrasonic pachymeter. METHODS: Anterior segment images were obtained in 185 Korean (298 eyes) using Visante OCT. Four different parameters (central corneal thickness, anterior chamber depth, anterior chamber angle, and internal anterior chamber diameter) were measured at four meridians (vertical, horizontal, 45 degrees, and 135 degrees). Afterwards, the same examiner performed A-scan ultrasonic pachymetry to measure central corneal thickness. RESULTS: Central corneal thickness values measured using Visante OCT were significantly less than those obtained using an A-scan ultrasonic pachymeter (p=0.000). Central corneal thickness, anterior chamber angle, and internal anterior chamber diameters were all smaller in females than in males (p<0.05). Anterior chamber depth, anterior chamber angle, and internal anterior chamber diameter showed a significant decrease according to increasing age in both sexes (p<0.05). CONCLUSIONS: Average values and changes of anterior segment structures in relation to age and sex were established using Visante OCT in Korean adults. These results may be useful as standard values in anterior segment surgeries as well as in the diagnosis and follow-up of certain anterior segment diseases.

PURPOSE: To evaluate the morphological differences between malignant and inflammatory lesions that arise from the cecal or pericecal region on CT by analyzing not only the mass itself but also the changes of surrounding structures. SUBJECTS AND METHODS: We reviewed CT scans of 38 cases of cecal lesions confirmed by pathology(16 malignant lesions and 22 inflammatory lesions). The analytical points were :the changes of bowel wall mass, the changes of surrounding structures, strands of retroperitoneal fat, pericecal fluid collection, and regional lymphadenopathy. RESULTS: The malignant bowel wall thickening(18.0mm) was thicker than inflammatory one(ll.4mm)(p < 0.001). Concentric bowel wall thickening was seen in 87.5%(14/16) of malignant lesions and 36%(8/22) of the inflammatory lesions. The pericecal fat stranding was circumferential in 84%(16/22) of inflammation and eccentric in 64%(916) of malignancy(p < 0.01). Pericolic fat infiltration was more extensive in inflammatory lesions(p < 0.005). The strands of retroperitoneal fat were more frequently found in inflammatory lesions(p < 0.05). The pericecal fluid collection was seen in 55%(12/22) of inflammatory lesions and none of malignant lesions. There was no difference in the presence of pericecal lymphadenopathy between the two groups. CONCLUSION: Malignant cecal masses have thicker and concentric bowel wall thickening, and narrower and eccentric pericolic fat infiltration. On the other hand, inflammatory masses have relatively thinner and eccentric bowel wall thickening, and more extensive and circumferential pericolic fat infiltration sometimes accompanied by abnormal fluid collection.

The clinical utility of thallium-201 SPECT combined dwith pharmacologic vasodilation induced by oral dipyridamole as an alternatiove to intravenous dipyridamole was incestigated in 21 patients who had concomitant coronary arteriography. Tomographic images were assessed visually. Sensitivity & specificity for overall detection of coronary artery disease were 93.7% and 80% respectively. Sensitivity & specificity for identification of indevidual diseased vessels were 84.6% and 87.5% for the left anterior descending artery, 75% and 84.6% for the right coronary artery, 60% and 100% for the left circumflex artery, respecitively. Of the 26 patients unergoing thallium scintigraphy 11 patients(42.3%) had some adverse effects between 20 and 50 minutes after oral dipyrdamole ingestion, including headache(26.9%), chest pain(26.9%), electrocardiographic changes(19.2%), and nausea(11.5%). Intravenous aminophylline was used to resolve these adverse effects in 8 patients & most of the adverse effects were subsided within 10 minutes. There was no ventricular arrhythmias, myocardial infarctions or deaths. In conclusion, oral dipyridamole thallium-201 SPECT is safe and accurate test for the overall detection of coranary artery disease and identification of disease in individual arteries. Furthermore it is useful for determining the necessities of coronary reperfusion and prognstically stratiofying the patients with coronary artery disease.

Periodic paralysis associated with thyrotoxicosis is characterized by intermittent flaccid paralysis of the skeletal muscle. The paralysis usually involve the skeletal muscle of the limbs, especially lower extrimities. In general, sensory function is intact. Involvement of respiratory, ocular or bulbar muscles is very rare, but bulbar and respiratoy invelvement may prove fatal. It is very rare a case that has severe clinical manifestation such as cardiac arrest. We report a case of thyrotoxic hypokalemic periodic paralysis presenting as cardiac arrest.

PURPOSE: To report a case of central retinal vein occlusion caused by iron deficiency anemia in a healthy young adult. CASE SUMMARY: A 23-year-old female was referred to the department of ophthalmology after 4 days of acute onset of decreased vision in her left eye. The best corrected visual acuity was 20/20 in the right eye and 10/20 in the left eye. There was no ocular pain, afferent pupillary defect or other ocular symptoms. Results of the anterior segment examination were normal. Fundus examination showed mild optic disc swelling, flame-shaped retinal hemorrhages around the optic disc, and vascular tortuosity with dilatation. The fluorescein angiography showed tortuous peripapillary veins, multiple blocked fluorescences due to retinal hemorrhages, and delayed arteriovenous transit time. All medical examinations and laboratory tests for the risk factors of central retinal vein occlusion were within normal limits, except for iron deficiency anemia. The patient was subsequently treated with oral iron. Three months after the first visit, the best corrected visual acuity was 20/20 in the patient's left eye with nearly normal fundus appearances and no iron deficiency anemia detected in laboratory tests. CONCLUSIONS: In cases of CRVO in young adults without other systemic diseases and risk factors, evaluation of the hematologic state may be necessary.

PURPOSE: To evaluate the effect of reduced volume of contrast media on vascular opacification and image quality in spiral CT of the chest. MATERIALS AND METHODS: Sixty patients referred for chest CT were examined withspiral CT with 60ml(n=30) or 90ml(n=30) of 30% ionic contrast media(Rayvist 300 , Schering, Germany) alternately.Injection rate of each group was as follows : 2.0 ml/sec for 20 seconds followed by 1.0 ml/sec for 20 seconds in 60ml group and 2.0ml/sec for 45 seconds in 90ml group. Twenty-five seconds scanning delay was employed. For the objective comparison of vascular opacification, CT numbers were measured at superior vena cava, ascending and descending aorta, right and left pulmonary artery, left atrium, and inferior vena cava. For the subjective comparison three radiologists scored the grade of vascular opacification and image quality blindly and independently. All data were analyzed statistically. RESULTS: The mean values of measured CT numbers in 90ml group were higher than those in 60ml group(p <.05) at the same level. The overall mean score of vascular opacification in 90ml group was 2.86, and 2.31 in 60ml group(p <.0001). In the overall mean score of imagequality, there was no statistically significant difference between 90ml group(2.46) and 60ml group(2.40). CONCLUSION: Althought there is some degradation of vascular opacification in 60ml group, overall image quality is not degraded. Therefore, 60 ml of contrast media can be used in spiral CT of the chest without degradation ofoverall image quality except in spiral CT angiography.
