PURPOSE: Atopic dermatitis is a chronic, inflammatory skin disease characterized by intense pruritus and an immunologic profile consistent with allergic disease. It is associated with increased eosinophil and IgE level and decreased INF-gamma production. We describe the result of a treatment with INF-gammaand assess the clinical, immunologic, and laboratory data of 12 patients with atopic dermatitis. METHODS: Twelve patients were treated for 12 weeks with 2x106 units/m2 INF-gamma by subcutaneous injection. General hematologic tests were done, and total eosinophil counts, eosinophil fractions, neutrophil fractions, and IgE levels were measured before the treatment, 2 weeks after the treatment, 12 weeks after the treatment serially. We also followed up the patients for 12 weeks after discontinuing INF-gammatherapy. RESULTS: All patients showed clinically significant improvement after 12 weeks of the systemic INF-gammatherapy. There was no clinical aggravation during the therapy period and the follow-up 4 weeks without the therapy. But the recurrence rate in the 12 weeks after discontinuing the therapy was about 40%. Eosinophil counts and eosinophil fractions were significantly decreased after the therapy. And, eosinophil counts and eosinophil fractions were increased in clinically aggravated patients during the 12 weeks of off-therapy. CONCLUSION: We conclude that INF-gammais an effective therapy in atopic dermatitis without significant side effects. The eosinophil counts and eosinophil fractions were decreased during the INF-gamma therapy, and increased in clinically aggravated patients after the off-therapy. There was no aggravation during the therapy. But 5 patients were clinically aggravated during the 12 weeks of off-therapy. Further studies for a long-term maintenance therapy and its side effect might be needed in chronic atopic dermatitis.

BACKGROUND: Carcinoembryonic antigen (CEA) is a glycoprotein on cellular surface, which is highly condensed in embryonic tissue and tumor of various kinds. Previous study found out that CEA may grow with various cancer or other diseases other than cancer as well. Besides, it is widely known that smoking also influences the rise in CEA. Among the same smokers, some of them show high CEA figures in serum when others remain in normal range. There are those whose pulmonary function is not influenced by smoking when that of others are susceptible to it. Therefore, this study was undertaken with an aim to study the relationship between serum CEA and pulmonary function by investigating how the change in pulmonary function caused by smoking influences serum CEA. METHODS: From Nov, 1997 to Feb, 2001, this study carried out tests on adult male smokers ages 35 to 64 who visited a hospital located in Kang Nung city. The subjects were divided into two groups: one group of 29 subjects with high CEA with over 6.0 ng/ml with normal colon study; the other group, which is the CEA normal group, consisted of 58 subjects selected through age adjusted random sampling. Data on personal information, smoking and clinical history was collected from a questionnaire. CEA was tested using radioimmunoassay of Abott. Pulmonary function was examined using Analyzer assembly Vmax 20C from Sensormedics Company. These examinations was limited to those who have been screened not to have cancer by chest X-ray, abdominal ultrasonography, and duodenofibroscopy. RESULTS: Smoking per day for the group with high serum CEA was 1.3 pack ( 0.4 pack), which was found to be significantly higher compared to that of normal group (P<0.01). Pack-years with high serum CEA group was 32.6 13.5 which was also comparatively higher than that of the normal group with 22.4 10.9 (P<0.01). Pulmonary function test indicated that FEV1 for the group with high serum CEA was 3.0 0.5 L, which marked lower than that of the normal group with 3.4 0.5 L (P<0.05). After compensating for age and pack years, FEV1 decreased in proportion to the rise in CEA. CONCLUSION: This study has established a link between serum CEA and daily smoking, pack years, and pulmonary function and found that FEV1 was inversely proportionate to the rise in CEA regardless of corrected pack years and daily smoking. Consequently, serum CEA alone is thought to be related to the pulmonary function. Therefore, it is advised that smokers with high serum CEA need to take heed of the influence on pulmonary function.

We experienced a case of isolated fetal pleural effusion diagnosed by antenatal ultrasonogram in the 33th week of gestational age. Chest PA at birth showed massive pleural effusion in both lungs. The serous pleural fluid changed to a milky nature after feeding so we diagnosed it as congenital chylothorax. The infant was managed by chest tube drainage, NPO & TPN with good response and was discharged on the 28th hospital day. We report the case with a brief review of its related literature.

PURPOSE: Perforator flap-using ischial sore reconstruction is performed in a prone position. But after the surgery, recurrence frequently occurs in a sitting position. In this sense, we introduce modified flap insetting method which closely resembles patient's sitting position to lessen the flap tension surgically. MATERIALS AND METHODS: Authors tried to check a skin tension difference between prone position and sitting position in normal people group and to find out the importance of performing flap insetting in hip flexion position. Healthy volunteers were collected (n=20) and designed the same length of 4 divided sections around the ischium. Lengths of each section were measured when hip joint was flexed to 90 degree and when both hip and knee joints were flexed to 90 degree and the statistical evaluation was performed. Twenty cases with ischial sore underwent reconstructive surgery using perforator flap under hip flexion position and followed-up for any recurrences. RESULTS: There was a meaningful difference between the joint flexed skin length and that of the neutral position. Flap showed sufficient thickness over 12 months. CONCLUSION: It seems that recurrence could be reduced when the reconstructed flap could sufficiently cover in a sitting position regarding its significant length difference in normal people group.

Purpose:
Dominant optic atrophy is one of the most common hereditary optic neuropathies, causing progressive bilateral vision loss that begins early in life. Optic atrophy 1 (OPA1) gene mutation brings about mitochondrial dysfunction, which results in clinical manifestations of dominant optic atrophy. Here, we report a case of dominant optic atrophy caused by the c.1334G>A mutation of the OPA1 gene, the first known case in Korea to our knowledge.Case summary: A 12-year-old female patient with no specific medical history or systemic symptoms visited our clinic complaining of a progressive decrease in vision in either eye. Slit-lamp microscopy, intraocular pressure, ocular motility, and pupil reflex were normal. However, her best-corrected visual acuity in both eyes was 20/100, and her color vision was reduced to 8/12 in Ishihara’s test. Fundus examination showed temporal pallor of the optic nerve head in both eyes, and a corresponding cecocentral scotoma was observed on Goldmann visual field examination. Optical coherence tomography revealed significant thinning of the peripapillary retinal fiber layer and macular ganglion cell layer in both eyes. Genetic examination confirmed the c.1334G>A mutation of the OPA1 gene.
Conclusions
We report a case of dominant optic nerve atrophy caused by c.1334G>A mutation of the OPA1 gene and its clinical manifestations.

PURPOSE: Until now, the rejection was diagnosed through a biopsy, but this method of diagnosis reflected the advanced tissue damage of the transplanted organ and contained the innate problem of being invasive. Activation of T lymphocytes, which occurs before the overt tissue damage has a pivotal role in rejection. In relation, our research attempted to evaluate the viability of analyzing the surface antigens of the peripheral blood activated T lymphocytes in mice after skin transplantation as a noninvasive and early diagnostic tool for diagnosis of rejection. METHODS: After the mouse's skin was transplanted, the expression patterns of activated T lymphocyte markers, CD44 and CD45RB were analyzed along with T lymphocyte markers, CD3, CD4, and CD8 using flow cytometry. The skins from the tails of allogeneic Balb/c (H2(d)) mice and syngeneic C57BL/6J mice were transplanted to C57BL/6J (H2(b)) mice as test and control groups, respectively. Peripheral blood, which was sampled from the tail every other day from day 3 to day 15 was stained with anti-CD44 (or CD45RB), anti-CD4 (or CD8) and anti-CD3 monoclonal antibodies simultaneously, and analyzed by 3-color FACS. Repeated ANOVA test and Mann-Whitey test were used to analyze the differences between the expression patterns of peripheral blood T lymphocyte surface antigen in the control and test groups (SPSS 8.0). RESULTS: Rejection occurred only in the test group from day 8 to day 13 (median: day 10). Although the proportions of CD3(+)lymphocytes (CD3(+)%), CD4(+)lymphocytes (CD4(+) %), and CD8 lymphocytes (CD8(+)%) showed no difference between the control and test groups, the total number of peripheral blood lymphocytes and the number of CD3(+)lymphocytes (CD3(+)) and CD8(+)lymphocytes (CD8(+)) decreased more sharply in the control group after day 7. The proportion and the number of CD44 CD3(+)lymphocytes, CD44 CD4(+)lymphocytes, and CD44(+) CD4(+) CD3(+)lymphocytes began to increase after day 7, to peak on day 11, and then to decrease, showing a significant difference from those of the control group. The proportion and number of CD44(+) CD3(+)lymphocytes, in particular, showed the most significant difference among these significant markers. The proportion and number of CD44(+) CD8(+) lymphocytes and CD44(+) CD8(+) CD3(+)lymphocytes showed similar trends to those of CD44(+) CD3(+) or CD44(+) CD4(+), but the differences between the subset proportions in control and test groups were statistically insignificant. No significant difference was observed in any subsets of the CD45RB antigen. CONCLUSION: CD44(+)CD3(+) lymphocytes representing activated T lymphocytes increased significantly compared to the control group during the rejection period of skin transplantation. The analysis of the expression patterns of surface antigen CD44 on peripheral blood T lymphocytes using flow cytometry is sensitive, safe, easily repeatable, and controllable, and, therefore, can be considered a promising tool for the diagnosis of rejection. However, the clear change in CD44 occurred between day 9 and day 13, when rejection was observed grossly. Therefore, it is regarded more useful as a screening test or follow-up indicator rather than as an early diagnostic tool.

PURPOSE: We explored whether a gender difference was evident in terms of the associations of snoring with hemoglobin A1c (HbA1c) and homeostatic model assessment-insulin resistance (HOMA-IR) levels in a healthy population without type 2 diabetes mellitus (DM). MATERIALS AND METHODS: We analyzed 2706 males and 4080 females who participated in the baseline survey of the Namwon Study. In terms of self-reported snoring frequency, participants were classified as non-snorers or occasional (1–3 days/week), frequent (4–6 days/week), or constant (7 days/week) snorers. Participants with DM, defined as a fasting blood glucose level ≥126 mg/dL and/or use of insulin or hypoglycemic medication, were excluded from the analysis. RESULTS: In females, the fully adjusted mean (95% confidence interval) HbA1c levels in non-snorers and in occasional, frequent, and constant snorers were 5.53% (5.47–5.59%), 5.53% (5.47–5.59%), 5.57% (5.49–5.64%), and 5.57% (5.51–5.64%), respectively, reflecting a dose-response relationship (p trend=0.004). Compared with female non-snorers, the risk of an elevated HbA1c level (top quintile, ≥5.9%) in constant snorers remained significant (odds ratio 1.30, 95% confidence interval 1.02–1.66) after full adjustment. In addition, in females, a significant linear trend in HbA1c level odds ratio by increased snoring frequency was apparent (p trend=0.019 in model 3). In contrast, no significant association between snoring frequency and HbA1c level was identified in males. No significant association between snoring frequency and HOMA-IR was detected in either gender. CONCLUSION: We discovered a gender-specific association between snoring and HbA1c level in a healthy, community-dwelling population free of DM.

PURPOSE: To estimate the long-term therapeutic efficacy and safety of adefovir dipivoxil in children and adolescents with chronic hepatitis B who have developed lamivudine resistance. METHODS: Sixteen patients (12 boys and 4 girls; ages 4.3~20.9 years; mean age 14.2 years) with chronic hepatitis B infection resistant to lamivudine therapy received adefovir (0.3 mg/kg/day, maximal dose 10 mg) orally for at least 9 months between March 2004 and April 2008. Each patient was followed up for a mean period of 27 months (range 9~49 months) until April 2008 at Kyungpook National University Hospital in Korea. Therapeutic responses to adefovir were evaluated at 12, 24, 36, and 48 months from the initiation of therapy using the Kaplan-Meier method. Response measurements included ALT normalization, HBV DNA negativization, 2 log(10) IU/mL decrement of HBeAg titer, HBeAg loss, and HBeAg/Ab seroconversion rate. RESULTS: Three (18.8%) of the 16 patients treated with adefovir showed HBeAg/Ab seroconversion. Kaplan-Meier estimates of cumulative ALT normalization were 12.5% (12 months), 43.8% (24 months), 63.5% (36 months), and 92.7% (48 months), respectively. Cumulative HBV DNA negativization was 6.7%, 30.0%, 45.6%, and 78.2% at 12, 24, 36, and 48 months, respectively. Cumulative 2 log(10) copies/mL decrement of HBeAg titer was 12.5%, 43.8%, 56.3%, and 86.9% at 12, 24, 36, and 48 months, respectively. Cumulative HBeAg loss and HBeAg/Ab seroconversion were 6.7% (12 months) and 22.2% (24 months), respectively. CONCLUSION: The long-term therapeutic efficacy of adefovir dipivoxil was favorable in children and adolescents with chronic hepatitis B who had developed lamivudine resistance. The long-term use of adefovir should be safe in children.
