PURPOSE: It has been reported that neovascularization of the optic disc (NVD) occurs in ocular ischemic syndrome, sickle cell hemoglobinopathy, ocular sarcoidosis, Eales' disease, and central retinal artery occlusion. However, NVD in acute ophthalmic artery occlusion had not been reported. Therefore, we report one unusual case of NVD in acute ophthalmic artery obstruction. METHODS: A 56 year-old man with complaint of abrupt decrease of visual acuity and periorbital discomfort underwent medical history taking, periorbital examination, fundus examination, and fluorescein angiography. He was followed up for 5 months RESULTS: Fundus examination showed segmentation of blood flow and diffuse retinal whitish opacity on the posterior pole around the center of the macula, without any cherry red spots in the perifoveal area. Fluorescein angiography showed a marked filling delay in the nasal retinal and choroidal circulations with a definite watershed zone involving the peripapillary choroid and macula. The retinal arteries filling and arteriovenous transit time were delayed. There was no light-perception vision and low intraocular pressure. Diabetes was found on systemic examination. Five weeks later, NVD and choroidal atrophy around the optic disc were detected. Panretinal photocoagulation was performed for the regression of NVD. NVD was regressed, but recurred.

Purpose:
Several studies have associated the serum vitamin D level with total testosterone levels and the prostate volume. Herein, we investigated the effect of vitamin D supplementation on testosterone, prostate, and lower urinary tract symptoms (LUTS) in men.
Materials and Methods:
Men over 40 years of age diagnosed with a vitamin D deficiency (25[OH]D <20 ng/mL) who received vitamin D supplementation for one year were included in the study and administered 25,000 IU of cholecalciferol every 2 weeks. Prostate ultrasound, uroflowmetry, postvoid residual urine volume measurement, and serological tests (serum testosterone levels, etc.) were performed upon diagnosis and one year later. Participants also answered the International Prostate Symptom Score (IPSS) and Aging Males’ Symptoms Scale (AMS) questionnaires.
Results:
A significant increase was observed in the vitamin D level following one year of vitamin D supplementation, with a significant decrease in the postvoid residual urine volume, total IPSS score and without a significant change in the prostate volume. Improved psychological subscale score of AMS questionnaire was observed with a statistical significance.
Conclusions
Vitamin D supplementation suppressed the increase in the prostate volume and improved the LUTS. Although there is no direct effect on serum testosterone levels, vitamin D supplementation helped improve hypogonadal symptoms.

Thyroid hormone resistance syndrome (RTH) is a rare disorder and is characterized by elevated levels of circulating free thyroid hormones, inappropriate secretion of thyroid stimulating hormone (TSH), and reduced peripheral tissue response to thyroid hormone. 90% of RTH subjects, when studied at the level of the gene, have been found to harbor mutations in the thyroid hormone receptor-beta(THRB) gene. These affected individuals have been shown to possess a variety of missense mutations, resulting from changes in a single nucleotide in the THRB gene that corresponds to amino acid alternation. However, insertion or deletion mutations in the THRB gene sequence are quite rare, and have been observed in only a very few cases. In this study, we describe two such cases, in which two members of the same family were determined to harbor an insertion mutation in exon 10, and had also been diagnosed with generalized RTH. This insertion mutation, specifically the insertion of a cytosine at nucleotide 1358 of the THRB gene, is, to the best of our knowledge, the first such mutation reported among RTH patients in Korea.

Gallbladder carcinoma is the most common primary hepatobiliary carcinoma and the fifth most common malignancy of the GI tract. The most common type of gallbladder carcinoma is adenocarcinoma. Squamous cell carcinoma of the gallbladder is rarer and is responsible for up to 12.7% of gallbladder tumors. A 78-year-old man was incidentally suspected of having a gallbladder mass on an abdominal CT scan and underwent laparoscopic cholecystectomy. Pathology results confirmed the mass as a squamous cell carcinoma. Here we report a case of keratinizing squamous cell carcinoma of the gallbladder and review the literature.

Juvenile dermatomyositis is an uncommon autoimmune disease with classic heliotrope discoloration of eyelids, erythematous skin rash of joints and proximal muscle weakness. Quite different from adults, malignancy is rarely accompanied in juvenile dermatomyositis. However vasculitis, muscle atrophy, calcification and gastrointestinal involvement are often observed in juvenile dermatomyositis. A six year old boy was admitted with chief complaints of general weakness and skin rash. Muscle biopsy was performed which was consistent with dermatomyositis. The patient was treated with intravenous immunoglobulin, steroid, methotrexate and physiotherapy. We report a case of juvenile dermatomyositis.

BACKGROUND: Despite extensive investigation, the clinical features and prognostic significance of the non-Q wave myocardial infarction, when compared with Q wave myocardial infarction, remain controversial. And no definite relationship between EKG findings and infarct related arteries has been reported. METHOD: A retrospective analysis was done on 205 patient with acute myocardial infarction who were undergone coronary angiography and left ventriculography. Among them, 30 patient with non-Q wave myocardial infarction and 175 patients with Q wave myocardial infarction. RESULTS: 1) There was no significant difference between the two groups in risk factors, prevalence of preinfarct angina and preinfarct heart failure. 2) The faction of patients with non-Q wave myocardial infarction who received thromobolytic therapy was significantly less, compared to patient with Q wave myocardial infarction(p<0.0001). 3) The patients with non-Q wave myocardial infarction had a smaller infarct size estimated by peak creatine phosphokinase(p<0.01). But there was no difference in Killip's classification and left ventricular ejection fraction. 4) In patients with non-Q wave myocardial infarction, 87% of the patients had one or more abnormal EKG finding other than Q wave, and the most frequent abnormal finding was primary T wave change. 5) The location of infarct-related artery was significantly different between group(p<0.0001). The most frequently involved coronary artery in non-Q wave myocardial infarction was left circumflex coronary artery, especially in patients with normal EKG findings. 6) There was no significant difference between the two groups in the prognosis. CONCLUSION: There were significant differences between non-Q wave and Q wave myocardial infarction in the infarct size and the location of infarct related arteries. but not in the risk factors, the prevalence of previous coronary artery disease and prognsis. Further prospective and collaborative studies should be performed to define conclusion.

Transitional cell carcinoma(TCC) of the urinary bladder shows marked heterogeneity in biological behaviors. Evidence has accumulated that biological markers may provide significant information to predict the potential aggressiveness of TCC. We have assessed the expression of the epidermal growth factor receptor (EGF-R), c-erbB-2 and p53 proteins in 56 cases of TCC to investigate the prognostic significance of differential expression of these oncoproteins using an immunohistochemical method. We analysed the expression patterns of these oncoproteins according to tumor stage and grade. And we assessed the probability of progression-free survival in stage T1 tumors according to their expressions. Positive rates of EGF-R (>+3 staining intensity), c-erbB-2 (intense membrane staining) and p53 proteins (>20% positive cells) were 73.2%, 37.5% and 42.9%, respectively. Invasive tumors had significantly higher positive rates of all three factors than did superficial tumors (p<0.005 for EGF-R and c-erbB-2, p<0.05 for p53). High grade tumors had significantly higher positive rates of c-erbB-2 and p53 proteins (p<0.005). In superficial tumors, T1 tumors had higher positive rate of p53 protein compared with Ta tumors (p<0.05). Twelve cases of superficial tumors (34.3%) were positive for EGF-R and negative for c-erbB-2 and p53 proteins. Nine cases of superficial tumors(25.7%) were negative for all three factors. In invasive tumors, however, 42.5% of the cases were positive for all three factors. The overexpression of p53 protein was the only useful marker to predict the rapid progression in stage T1 tumors (p<0.05, log-rank test). These results suggest that the differential overexpression of EGF-R, c-erbB-2 and p53 proteins could be useful to depict tumor aggressiveness of TCC of the urinary bladder. And, the overexpression of a p53 protein may be a useful marker to predict the possibility of rapid progression in stage T1 tumors.
