Purpose: To report a case of compressive optic neuropathy due to breast cancer metastasis to the periorbital lesion 26 years after the treatment of primary cancer. Case summary: A 64-year-old female presented with headache, facial pain and visual disturbance in her left eye for four months. The patient had received chemotherapy and radiotherapy after left breast modified radical mastectomy for invasive ductal carcinoma 26 years previously, and right breast wide resection with axillary dissection nine years earlier. Best corrected visual acuity was 20/20 in the right eye and 8/20 in the left eye. The color perception test showed abnormal findings in the left eye. MRI and PET-CT revealed an enhancing mass in the left periorbital area that was compressing the optic nerve. Partial resection of the tumor and left orbital wall was performed. Adjuvant chemotherapy and radiotherapy was performed after the operation. After two months later, the best corrected visual acuity was 20/20 in the left eye, and the color perception test showed normal findings, which have been maintained for one year. Conclusions: Prompt management can result in visual recovery in patients with compressive optic neuropathy caused by breast cancer metastasis. J Korean Ophthalmol Soc 2010;51(8):1161-1165

Objective: Mononeuritis multiplex is an extra-articular manifestation associated with rheumatoid arthritis. This study set out to investigate its clinical characteristics in Korea. Methods: Clinical characteristics and laboratory data were compared retrospectively by review of medical records between 12 patients with mononeuritis multiplex (case) and randomly selected 116 age-matched patients without mononeuritis multiplex in patients with rheumatoid arthritis (control). Results: Mean age of the case group was 51.8±8.4 years old with 7 males and 5 females which showed higher prevalence of male gender compared to the control group (p<0.05). There was no difference in mean duration of disease between two groups. Upper limbs, lower limbs and both upper and lower limbs were involved in 3, 7 and 2 patients, respectively. Major symptoms were tingling (66.6%), paresthesia (33.3%), pain (33.3%), foot drop (33.3%), or muscle weakness (16.7%). Skin ulceration was accompanied in 3 patients, but vasculitis of other organs was not found. Mean C-reactive protein level in the case group was 7.6±6.7 mg/dL, which was higher compared to 2.4±3.1 mg/dL in the control group (p<0.05). Rheumatoid factor was positive in 83.3% of the case, however positive rate and titer showed no significant difference with the control group. There was no difference in other extra-articular manifestations between two groups. Six patients were treated with glucocorticoid and immuno-suppressants and 6 patients with only glucocorticoid1 for 6.8±7.1 weeks. Symptoms improved after treatment in 10 patients but, it lasted in 2 patients. Conclusion: Rheumatoid arthritis associated mononeuritis multiplex was more prevalent in males with higher CRP levels, and responded well to medical intervention including glucocorticoid, and immunosuppressants.

Objective: Rheumatoid arthritis has various extra-articular manifestations including rheumatoid vasculitis. Angiotensin converting enzyme (ACE) gene shows insertion/deletion polymorphism and has II, ID, DD genotypes. ACE gene is related with vasoconstriction and endothelial dysfunction in cardiovascular disease. This study was undertaken to determine the association between ACE gene polymorphism and rheumatoid vasculitis. Methods: Twenty-nine patients were collected as rheumatoid vasculitis group. DNA was isolated from blood samples collected from 114 Korean rheumatoid arthritis patients meeting American College of rheumatology 1987 revised criteria, and 114 healthy control group. Genotyping for the angiotensin converting enzyme gene insertion/deletion polymorphism was performed by polymerase chain reaction method. Results: As vasculitis manifestation, 15 patients showed neuropathy, 13 showed scleritis, 3 showed skin rash. In rheumatoid vasculitis group, II, ID and DD polymorphism was seen in 8 (27.6%), 15 (51.7%), 6 (20.7%) patients respectively and 39 (34.2%), 57 (50.0%), and 18 (15.8%) in normal controls. There was no skewing of ACE I/D polymorphism in compared with normal group. In rheumatoid arthritis control group, II, ID and DD polymorphism was seen in 37 (32.5%), 64 (56.1%), and 13 (11.4%) patients. Among rheumatoid arthritis patient, there was no significant difference between patient with vasculitis and without vasculitis. Conclusion: Our results showed that genetic polymorphisms of angiotensin converting enzyme insertion/deletion gene has no association with the susceptibility to rheumatoid vasculitis.

A multi-functional indoor smog chamber was designed and evaluated lo investigate photochenical or water vapor reaction mechanisms of air pollutants. Various smog chamber experiments could be conducted using ambient air or purified air in this smog chamber. The smog chamber consisted of a housing, a Teflon bag, blacklights, injection ports, sampling ports, and utility facilities. The characteristics of light source, the wall losses of air pollutants, and the quality of purified air were experimentally investigated. The maximum NO₂ photolysis rate was 1.10min^(-1). In a 2.5-m³ Teflon bag, the wall losses of ambient O₃, NO, and NO₂were 1.2~2.4×10^(-3)min^(-1), 0.7~2.0×10^(-3)min^(-1), and 0.4-2.0×10^(-3)min^(-1), respectively. The wall loss of ambient particles ranging 0.05 to 0.2㎛ was 1.8~5.4×10^(-3)min^(-1), which was slightly higher than those of ambient gaseous species. The purified air supply system provided high quality of air with NO₂, < 1 ppb, and total hydrocarbons <5 ppb.
