The number of post-irradiated surgical specimen appears to have risen in recent years due to the increasing utiliz ation of radiotherapy for cancer patients. Radiation therapy damages cells by its effects on the deoxyribonucleic acid and the spectrum of injury ranges from acute self-limited lesion to irreversible chronic lesion. We reviewed 24 cases of post-irradiated specimen and thought that time interval is the main factor influencing the morphologic change. Within six weeks, the individual cytologic changes such as biz arre nuclei, altered nucleus/cytoplasm ratio, amphophilic and vacuolated cytoplasm are noted. Chronic injury resulting from progressive changes in the fibrovascular tissue of the radiated area occur in six months after the initial course of radiation and the vascular changes of intimal thickening and fibrosis, foamy histiocytes within media, periadventital fibrosis and chronic inflammatory cells infiltration are present. Althouhg above mentioned finding are not pathognomonic, we thought them quite constant nd reproducible characteristics of radiation injury.

To analyse the age of onset, etiologic microorganisms, clinical manifestations, managements and genetic variation of chromic granulomatous disease, the authors reviewed four patients who were diagnosed as CGD at Department of Pediatrics, Seoul National Univesity Children's Hospital. They were siblings in relationship-two of them were brothers, the others were brother-sister. @ES The results were as follows; 1) Initial manifestations developed within 1 year old, and lymphadenopathy associated with BCG vaccination was the most common. 2) In culture study of micro-organism, catalase positive microorganisms such as Staphylococcus aureus, Serratia marcescens, Coagulase (-) Staphylococcus, Enterococcus, Proleus vulgaris, Klebsiella pneumoniae, E. coli and fungus such as Candida albicans were isolated. In 2 cases, culture study revealed no growth. 3) Fever, lymphadenopathy, hepatomegaly, suppurative dermatitis and pneumonia were the most common manifestations. In most of cases, antituberculous medications were administered under the impression of tuberculosis without response. 4) Immunologic screening tests including B-cell system, T-cell system, and complement system were within normal limit except NBT test. 5) In spite of severe infections, NBT scores of all the cases were less than those of controls. Liver biopsies of 3 cases showed granuloma formation with characteristic yellow brown pigment-laden macrophages.

A clinical analysis was done on 134 cases with bronchial asthma who were admitted to the Department of Pediatrics Yeungnam University from May 1987 to October 1991. The results were as follows: 1) The peak age of bronchial asthma was under 2 years. The sex ratio of male to female was 2.9:1. 2) The outbreak of bronchial asthma was most common in fall, especially in September. 3) The past history of other allergic diseases were present in 22.4% of patients (30/134 cases), and the previous bronchiolitis in infancy were experienced in 12.7% of patients (17/134 cases). 4) According to the skin test for allergens done by RAST, the most common allergens were Mites and House dust. 5) Eosinophilia (T.E.C>250/min) was found in 29.1%t of patients, and elevated lgE level (>200 IU/ml) was found in 63.2% of patients. 6) No significant differences in the serum lgE level were found between male and female patients. No significant differences in the serum lgE level were found between asthma patients with and without other allergic diseases. 7) The serum lgE level of school aged patients was significant higher than that of preschool aged (p<0.01).

Purpose:
To distinguish the dominant eye in patients with intermittent exotropia by comparing the width of the foveal avascular zone (FAZ), the vascular density (VD), and the choroidal thickness (CT) in both eyes.
Methods:
A total of 34 subjects with intermittent exotropia were enrolled. Optical coherence tomography angiography (OCTA) was performed after discrimination of the dominant eye using a prism cover test (PCT). FAZ widths in the superficial capillary plexus (referred to here as superficial FAZ or SFAZ) and in the deep capillary plexus (deep FAZ or DFAZ); VDs of the 1-mm fovea and 3-mm parafovea, specifically the superficial capillary plexus density (SCPD); and CT measured by OCTA were compared between both eyes using a one-sample t-test. These abovementioned parameters were compared between dominant and non-dominant eyes through Pearson’s correlation analysis.
Results:
The widths of SFAZ and DFAZ, the 1-mm fovea and 3-mm parafovea SCPDs, and CT of dominant eye showed positive correlations with respect to the non-dominant eye. Although there was no statistically significant difference in SFAZ and DFAZ widths, the 3-mm parafovea SCPD, or CT between eyes, the 1-mm fovea SCPD in the non-dominant eye showed a statistically significant higher density than that of the dominant eye (p = 0.039).
Conclusions
Our results suggest that the higher 1-mm fovea SCPD in the non-dominant eye is due to the secondary development of capillaries around the FAZ of the non-dominant eye after the retina of both eyes had developed to some extent.

This study aimed to investigate structural differences in the retinal and choroidal blood vessels before and after patch occlusion treatment in patients with amblyopia using optical coherence tomography angiography (OCTA) and to determine whether these differences are related to clinical improvement in patients. A total of 26 eyes of 17 patients with monocular or binocular amblyopia who underwent patch occlusion treatment for at least 1 month were retrospectively enrolled. The width of the foveal avascular zone, retinal blood vessel density, choroidal thickness, and choroidal vascularity index (CVI) measured by OCTA were compared before and after the treatment; the correlation with change in best-corrected visual acuity (BCVA) was analyzed for the data showing statistically significant differences. The mean BCVA of amblyopic eyes before and after patch occlusion treatment was 0.41 ± 0.23 and 0.25 ± 0.16 in logarithm of the minimum angle of resolution units, respectively. A decrease of about 2% in CVI was observed after the treatment (p = 0.011). The correlation between the changes in CVI and the changes in BCVA were insignificant (Rs = 0.086, p = 0.718). The results indicated that a decrease in CVI was observed after the patch occlusion treatment, but the relationship between CVI and BCVA could not be established. Patch occlusion treatment in amblyopia appears to affect the changes in the choroidal vessels and stroma.

There was no significant difference in morbidity and mortality between those that received simultaneous operation for coronary artery disease and peripheral vascular disease versus those that received coronary artery bypass graft alone. Simultaneous operation is also cost effective. A 46 year-old patient with resting chest pain and intermittent claudication was diagnosed as unstable angina and Leriche's syndrome. We performed simultaneous revascularization for coronary artery stenosis with internal mammary artery and right gastroepiploic artery and a bifurcated vascular graft interposition between in the aorta, left common iliac and right femoral arteries for Leriche's syndrome. The postoperative coronary angiogram and aortogram revealed a good patency of the arterial conduits and vascular graft. He has been followed for 12 months without any problem.

PURPOSE: The aim of this study was to investigate the current prevalence of protein-energy malnutrition (PEM) and the nutritional status of hospitalized pediatric patients. METHODS: We evaluated the nutritional status of the 200 patients from February to July 1994 and the 233 patients from February to July 1999 admitted to Pediatric Department of Chosun University Hospital. Nutritional status was assessed by anthropometric and laboratory data. The nutritional status was classified according to based on the Waterlow criteria and using the laboratory data obtained between 3 days to 5 days after admission. RESULTS: 1) The prevalence of acute PEM (weight for height) was as follows: severe, 0.5%; moderate, 7%; mild, 18%; and none, 74.5% in 1994 and severe, 2.24%; moderate, 3.59%; mild, 19.73%; and none, 74.4% in 1999. 2) The prevalence of chronic PEM (height for age) was as follows: severe, 5%; moderate, 5.5%; mild, 25.5%; and none, 64% in 1994 and severe, 2.24%; moderate, 4.04%; mild, 22.87%; and none, 70.85% in 1999. There was not a statistically significant difference between 1994 and 1999. 3) The prevalence of PEM according to age group, all age group had in general higher prevalence of mild PEM. 4) Values for hemoglobin and albumin were below than total lymphocyte values in PEM. CONCLUSION: The prevalence of acute or chronic PEM was common in hospitalized children. Therefore, the assessment of nutritional status may an important role to establish effective nutritional support and to improve their subsequent hospital course in hospitalized pediatric patient
