Recently, in leprosy patients the frequency of the blindness due to corneal disorder has been increased. We evaluated factors influencing corneal involvement in leprosy patients for the purpose of early detection and treatment of the preventable causes of the blindness. In 100 eyes of 100 leprosy patients and 50 eyes of 50 control who had no abnormality in ocular examination. Each patient was examined with corneal sensitivity test, Schirmer test(Type I) and was graded according to severity of lagophthalmos. The results were as follows: 1. 28 eyes(28%) of the leprosy patients and 3 eyes(3%) of the control patients showed less than 5mm wetting of fiter paper respectively. 2. Corneal sensation was decreased moderately or markedly in 42 eyes(42%) of the leprosy patients and 7 eyes(14%) of the control patients respectively. 3. The values of Schirmer test and corneal sensation were decreased with increasing duration of the disease. 4. In leprosy patients, 32 patients(32%) were showed lagophthalmos. The grade of lagophthalmos was increased with increasmg duration of the disease. These results suggest that leprosy patients should be followed closely for factors(corneal sensation, decreased lacrimation, lagophthalmos) affecting cornea and that treatment directed towards this problem should be initiated early.

PURPOSE: To investigate the effect of triamcinolone acetonide (TA) on the survival, nitric oxide (NO) production, and migration of cultured human trabecular meshwork (TM) cells. METHODS: After exposure to TA, indomethacin, and dexamethasone for 2 days, the survival and nitrite production of the primarily cultured human TM cells were assessed with MTT and Griess assays respectively. The effect of co-exposure to the NO donor, sodium nitroprusside, was also assessed. A migration assay was done to evaluate the effect of TA on the activity of TM cells. RESULTS: Cellular survival increased after exposure to TA at low concentration but decreased at high concentration. TA decreased the production of NO significantly (p<0.05). Exposure to indomethacin and dexamethasone revealed similar results. TA reversibly inhibited the migration of TM cells. CONCLUSIONS: TA decreases the production of NO and inhibits the migration of TM cells. TA at high concentration decreases cellular survival accompanied with decreased NO production. These effects of TA on TM cells may result in the elevation of intraocular pressure.

In 1978, a nonprogressive corneal dystrophy was seperated from other causes of congenital opacification on the basis of unique clinincal findings and characteristic electronmicroscopic findings. This disorder, termed congenital hereditary stromal dystrophy, appears to the result of disordered stromal fibrogenesis. Recently, the autors have experienced 4 members of a family with typical electronmicroscopic findings of congenital heaeditary stromal dystrophy of the cornea. In this report we describe the characteristic findings of congenital hereditary stromal dystrophy.

PURPOSE: This study aimed to determine the amino acids composition, safety and efficacy of formulas recently developed by Korean dairy companies for children with inherited metabolic disorder. METHODS: The determination of amino acids concentration was performed on eight Korean formula samples. The samples were hydrolyzed with 6N HCL or performic acid and analyzed by amino acid analyzer. RESULTS: No phenylalanine, methionine or leucine was observed in PKU-1 and PKU-2 Formulas, Methionine-Free and Leucine-Free Formula, respectively. BCAA-Free Formula was free from leucine, isoleucine, and valine and MPA Formula did not contain methionine and valine. Protein-Free formula did not include any amino acids. UCD Formula contained arginine but was free of alanine, aspartic acid, glutamic acid, glycine, histidine, proline and serine. Methionine-Free Formula contained higher amounts of cystine and tyrosine was higher in PKU-1 and 2 Formulas. The amounts of isoleucine and threonine were minimal in MPA Formula. CONCLUSION: This study confirmed that the eight special formulas, developed for the first time by a Korean dairy company for children with inherited metabolic disorder contain appropriate amino acids with proper contents. Both the total amino acid amounts and specific amino acid concentrations of the formulas were appropriate for related diseases, which could be used safely by the patients with inherited metabolic disorder. For UCD Formula that contains arginine, we suggest that arginine be removed from the formula in order to use for any urea cycle defect patients before the specific diagnosis is made.

We experienced an extremely rare case of proximal epithelioid sarcoma (PES) of the vulva in a 77-year-old woman. After history taking and physical examination, the patient was tentatively diagnosed as having Bartholin’s cyst in the right labium. Based on histopathological and immunohistochemical (IHC) findings, however, a final diagnosis of PES of the vulva was made. After receiving CyberKnife treatment, the patient survived but with recurrent episodes and poor prognosis. In conclusion, our case indicates that patients with PES of the vulva should be appropriately managed with radiotherapy after a differential diagnosis based on histopathological and IHC findings.

To provide a basis for studying the pharmacological actions of tetracaine.HCl, we analyzed the membrane activities of this local anesthetic. The n-(9-anthroyloxy) stearic and palmitic acid (n-AS) probes (n = 2, 6, 9, 12 and 16) have been used previously to examine fluorescence polarization gradients. These probes can report the environment at a graded series of depths from the surface to the center of the membrane bilayer structure. In a dose-dependent manner, tetracaine.HCl decreased the anisotropies of 6-AS, 9-AS, 12-AS and 16-AP in the hydrocarbon interior of synaptosomal plasma membrane vesicles isolated from bovine cerebral cortex (SPMV), and liposomes derived from total lipids (SPMVTL) and phospholipids (SPMVPL) extracted from the SPMV. However, this compound increased the anisotropy of 2-AS at the membrane interface. The magnitude of the membrane rotational mobility reflects the carbon atom numbers of the phospholipids comprising SPMV, SPMVTL and SPMVPL and was in the order of the 16, 12, 9, 6, and 2 positions of the aliphatic chains. The sensitivity of the effects of tetracaine.HCl on the rotational mobility of the hydrocarbon interior or surface region was dependent on the carbon atom numbers in the descending order 16-AP, 12-AS, 9-AS, 6-AS and 2-AS and on whether neuronal or model membranes were involved in the descending order SPMV, SPMVPL and SPMVTL.

Arteriovenous malformations are degenerative lesions of the gastrointestinal tract that occur with a frequency that increases with increasing age. Although the bleeding caused by arteriovenous malformations is typically chronic, slow, intermittent and recurrent, 15% of patients with arteriovenous malformations present with massive bleeding. Any part of the gastrointestinal tract can be involved and arteriovenous malformations usually appear on endoscopy as either flat or elevated discrete bright red mucosal lesions. There are a few cases of colonic arteriovenous venous malformations with a polypoid appearance with some of their endoscopic treatments resulting in profuse bleeding from the remnant stalk. We encountered a case of a polypoid arteriovenous malformation in the colon of a 69-year-old patient with active gastrointestinal bleeding. The patient was treated successfully by an endoscopic polypectomy with a detachable snare.

PURPOSE: We conducted this study to assess the effect of oral application of bovine colostrum on the plasma endotoxin and TNF-alpha following the abdominal surgery. METHODS: 46 patients who underwent the abdominal surgery were evenly enrolled in a prospective, randomized, double blind and placebo-controlled study. The patients were preoperatively managed by oral application of 20 g of a bovine colostrums or placebo (nonfat dried milk) per a day for 3 days. In both groups, endotoxin was sequentially determined pre-, intra- and postoperatively by a modified limulus amebocyte lysate test. TNF-alpha and CRP were also measured. The clinical course was followed and compared in both groups. RESULTS: The colostrum group showed significantly lower level of endotoxin and TNF-alpha compared to the placebo group. CRP did not differ in both groups. Clinical event did not occur in both group until the discharge. Colostrum group tends to have a lower incidence of fever and leukocytosis without statistic significance. CONCLUSION: Prophylactic preoperative oral application of bovine colostrum lower the plasma level of perioperative endotoxin and TNF-alpha. Further studies were needed for the relation of clinical effect and preoperative oral application of bovine colostrum.

OBJECTIVE: To explore the incidence, characteristics, complications and socioeconomic impacts associated with falls in community-dwelling elderly. METHODS: From September 1, 2015 to October 12, 2015, a questionnaire-based survey was conducted involving a total of 2,012 elderly who lived in Guro-gu (Seoul), Yeongdeungpo-gu (Seoul), Yangpyeong-gu (Gyeonggi-do), Dalseong-gu (Daegu), and Jung-gu (Daegu). The subjects were interviewed using a structured questionnaire to obtain demographic characteristics and comprehensive falling histories. The socioeconomic cost related to falls was estimated using the statistical data provided by the Health Insurance Review and Assessment Service. RESULTS: Falls were recorded in 666 out of the 2,012 subjects (33.1%) during the past year. Frequent falls occurred during December, in the afternoons, when the floor was slippery. The most common injuries included the low back and the most common injury type was sprain. The total direct costs related to falls involving the 2,012 subjects were 303,061,019 KRW (Korean won). The average medical cost related to falls in the 2,012 subjects was 150,627 KRW and the average medical cost of 666 subjects who experienced falls was 455,047 KRW. Estimates of the total population over the age of 60 years showed that the annual direct costs associated with falls in Korea over the age of 60 years were about 1.378 trillion KRW. CONCLUSION: This study was conducted to explore the incidence, characteristics, complications, and socioeconomic impacts of falls in community-dwelling elderly. This study is expected to be used as a source of basic data for the establishment of medical policy for the elderly and the development of a fall prevention program for the elderly in Korea.
