1.Sarcoidosis, Presented as Recurrent Eyelid Masses.
Journal of the Korean Ophthalmological Society 2004;45(9):1590-1595
PURPOSE: Sarcoidosis is a granulomatous inflammation that can affect all organs, and the initial manifestation is sometimes ophthalmologic disease. The purpose of this article is to report the diagnosis of ocular sarcoidosis for a patient whose chief complaint was recurrent eyelid mass without any other ophthalmologic symptoms or signs. METHODS: A 43-year-old female had an 8-month history of bilateral upper eyelid swelling, right upper eyelid mass, and right ptosis. She had received localized steroid injection at a local dermatologic clinic. On physical examination, there were hard and fixed eyelid masses and mechanical ptosis due to an eyelid mass in the right upper eyelid. Mass excision and biopsy were performed, and a pulmonology specialist was consulted to evaluate the nodule on chest X-ray RESULTS: The patient's condition had been diagnosed with multiple chalazia at the first pathologic reading, but it was diagnosed with sarcoidosis at the second pathologic reading, which was requested because of recurrence. The diagnosis of sarcoidosis was based on chest PA, and chest CT, and was confirmed by lung biopsy specimen. CONCLUSIONS: In the case of recurrent eyelid mass, sarcoidosis should first be ruled out.

Splenic artery aneurysms are an uncommon form of vascular disease that carry the risk of rupture and fatal hemorrhage. Precise cause of splenic artery aneurysms are not be established, the most common pathologic finding is defect of the media. Splenic artery aneurysms occur in patient with multiple pregnancies, portal hypertension, splenomegaly, after orthotopic liver transplantation and fibrodysplasia. Most patients who are diagnosised with splenic artery aneurysm are asymptomatic. Arteriography is a confirmed diagnostic method for detecting splenic artery aneurysms and searching the location of aneurysms. Operative treatment and therapeutic catheter embolization have been used for treatment of splenic artery aneurysms.

PURPOSE: To compare intraoperative parameters and postoperative results between divide-and-conquer and multiple phaco-chop technique. METHODS: Two different techniques were performed by one operator on the patients with bilateral cataract. One eye was phacoemulsified by divide-and-conquer technique (D eye), and the other was performed by multiple phaco-chop technique (M eye). Changes of central corneal thickness during the operation, total phaco-time and phaco-energy were measured. RESULTS: Total 29 patients were included. The change of central corneal thickness were 8.4 +/- 11.8 microm in D eye and 11.5 +/- 16.7 microm in M eye, which showed no significant difference (p = 0.350) and total phaco-time were 70.1 +/- 32.9 seconds in D eye and 71.1 +/- 55.0 seconds in M eye, which also showed no significant difference (p = 0.689). However, phaco-energy were 12.4 +/- 8.3 power x s in D eye and 8.4 +/- 9.9 power x s in M eye, and this result showed significantly larger energy when using divide-and-conquer technique (p < 0.001). CONCLUSIONS: There was no significant difference in change of central corneal thickness and phaco-time between two techniques, divide-and-conquer and multiple phaco-chop technique. However, significantly smaller phaco energy was used by multiple phaco-chop technique compared with divide-and-conquer technique.

Journal of the Korean Ophthalmological Society 2006;47(8):1189-1196
PURPOSE: Thyroid-Associated Orbitopathy (TAO) presents with highly variable clinical characteristics. We hypothesize that the underlying thyroid status predisposes a patient to different clinical characteristics of TAO. METHODS: We retrospectively studied the clinical data of 385 patients from the New York area who were referred to our clinic and diagnosed with TAO from Jan 1990 to Dec 2000. We divided the 385 patients into three groups: Graves' hyperthyroid, euthyroid, and hypothyroid, and analyzed them statistically. RESULTS: Three hundred thirty-one (86%) patients were hyperthyroid, 25 (6.5%) were euthyroid, and 29 (7.5%) were hypothyroid. The average age of TAO presentation in each group was 46.7, 46.1, and 49.9 years, respectively. The female-male ratio in each group was 5.25, 3.17, 13.5:1, respectively (p>0.05). The average time from thyroid disease to TAO in the hyperthyroid and hypothyroid groups was 16.6 and 38 months, respectively (p<0.05). The hyperthyroid group had more proptosis (76.1 vs. 41.4%, p=0.0001<0.05) than the hypothyroid group. CONCLUSIONS: TAO has different clinical characteristics depending on thyroid status. The hyperthyroid group has a short disease interval and more severe clinical course of TAO than the hypothyroid group.

PURPOSE: To determine the epidemiologic and clinical characteristics of thyroid-associated orbitopathy (TAO). METHODS: We retrospectively studied the clinical data of 385 patients from the New York City area diagnosed with TAO from January 1990 to December 2000. The total cases were divided into male and female groups and age-adjusted relative incidence rates were obtained to plot the incidence curve and clinical characteristics. Statistical analysis was applied to the collected data. RESULTS: The average age of patients with TAO was 46.3 years for females and 50.1 years for males. The female-male ratio was 5.31:1. In 23.3% of patients, the diagnosis of TAO was made simultaneously with their thyroid disease. In 75% of cases, the diagnosis was made within 18 months of the presentation of thyroid disease. Soft tissue involvement was noted most frequently in 311 (80.8%), eyelid retraction in 306 (79.5%), proptosis in 278 (72.2%), restrictive myopathy in 234 (60.8%), and compressive optic neuropathy in 43 (11.2%) of 385 patients. CONCLUSIONS: TAO has variable and different epidemiologic and clinical characteristics according to sex and age.

Neovascular glaucoma is a subtype of secondary glaucoma that is characterized by proliferation of fibrovascular tissue in the anterior chamber angle. This condition may be acutely aggravated by carotid revascularization therapies. There have been few previous reports of acute aggravation of neovascular glaucoma following carotid artery stenting. We report the case history of a patient who had acute exacerbation of neovascular glaucoma following carotid artery stenting and required surgical management.

PURPOSE: For patients with breast carcinoma, immunohistochemical markers are important factors in determining the breast cancer subtype and for establishing a therapeutic plan, including the use of neoadjuvant chemotherapy (NACT). However, it is not clear whether the expression of certain markers changes after NACT. METHODS: We assessed estrogen receptor (ER), progesterone receptor (PR), human epidermal growth factor receptor 2 (HER2), Ki-67, p53, and Bcl-2 expression in specimens from 345 breast cancer cases before and after NACT. We analyzed the association between response to NACT and the expression of the markers in pre-NACT specimens. We also compared the expression between pre- and post-NACT specimens. RESULTS: ER and PR expression was negatively associated with pathological complete response (pCR). HER2 was associated with pCR in all cases, but the association was lost when the cases were subdivided according to hormone receptor status. The pre-NACT tumor size of cases with pCR after NACT was smaller than that of cases with residual disease. HER2-enriched and triple-negative breast cancers were more likely to achieve pCR than luminal A type cancers. PR expression and the Ki-67 index decreased after NACT. A decrease in the Ki-67 index was also demonstrated in hormone receptor positive and HER2-enriched subtypes, but no similar tendency was observed in the triple-negative subtype. CONCLUSION: A patient with breast cancer scheduled for NACT should be assessed for the breast cancer subtype, as this will influence the treatment plans for the patient. The expression of PR and Ki-67 after NACT should be interpreted carefully because NACT tends to reduce the expression of these molecules.

PURPOSE: To evaluate visual performance as well as patient satisfaction and to explore factors associated with clinical outcomes in pseudophakic monovision acquired after bilateral phacoemulsification and sequential monofocal intraocular lens (IOL) implantation. METHODS: The present retrospective study examined patients with pseudophakic monovision. Preoperative and postoperative binocular uncorrected distant visual acuity (UCDVA), uncorrected near visual acuity (UCNVA), refractive errors and postoperative near stereopsis were measured. Postoperative measurements were obtained at least 6 months after the fellow eye surgery. Patient satisfaction and independence from glasses were evaluated using a questionnaire. RESULTS: Preoperative and postoperative binocular UCDVA, UCNVA, and differences in spherical equivalent refractive error were statistically significant. Postoperative near stereopsis was 107.1 arcsec. Questionnaire responses showed that 71.4% of patients were less dependent on glasses and 85.7% were satisfied with the postoperative visual performance. Various designs of monovision, such as crossed monovision or customized minimonovision with moderate myopic defocus showed the same level of patient satisfaction. Patients who were older than 60 years or had poorer preoperative binocular UCDVA showed higher satisfaction. CONCLUSIONS: Pseudophakic monovision is an effective approach for managing loss of accommodation after cataract surgery, especially in patients older than 60 years.

Dental infection which has been harmful to human for a long time occurs when the balance of three factors; host, environment and source of infection are broken and occurs especially when the balance of the resistance of the host and the toxin of bacteria are collapsed. Though dental-origin infection causes severe pain, it is commonly localized in gingiva, pulp and the surface of alveolar bone and as the decrease of its prevalence due to the development of antibiotics and the ease of treatment by a simple aids, there are no case that proper caution are made for the infection. Expecially in case of patient with infectious Hansen's disease(leprosy), as they have many other medical diseases, dental disease are mostly passed by. As oromaxillary infection can end up to death, though it is hard to treat a severly progressed myofascial space infection, general understanding about the reason, the pattern of spreading, treatment, prevention of it should be needed to make actual management in the situation of an doubtless developing of infection in patient treatment and situation of suspicious development of early myofascial space infection. Since last 5 years, 36% of the patients were hospitalized due to their dental infection and consistent advertising and treatment resulted in a gradual decrease of it.
