PURPOSE: We evaluated the risk factors and related results of residual diplopia and enophthalmos in patients who had orbital wall fracture repair. METHODS: 50 patients with orbital wall fracture who were followed up for at least 6 months postoperatively were included in this study. We analyzed effects of the patient age, timing of surgery, size and location of fracture on development of postoperative diplopia and enophthalmos. RESULTS: 32 patients had diplopia and 16 patients had enophthalmos greater than 2 mm. Among 32 patients with preoperative diplopia, 9 patients experienced postoperative diplopia. Among 16 patients with preoperative enophthalmos, 5 patients experienced postoperative enophthalmos. Delayed timing of surgery was a significant factor for development of postoperative diplopia and enophthalmos. Age of the patients and fracture size were not significant factors for development of postoperative diplopia and enophthalmos. CONCLUSIONS: Early surgical repair of orbital wall fractures decreases the incidence of residual diplopia and enophthalmos. Preoperative assessment of multiple variables could help to achieve cosmetical and functional better results.

PURPOSE: To evaluate the efficacy of vitrectomy in patients with diabetic macular edema. METHODS: The results of pars plana vitrectomy in 10 eyes were analyzed. Major outcome measurements were preoperative and postoperative best corrected visual acuity, fundus findings of macula, and postoperative complications. All eyes had at least 4 months of follow- up after surgery. RESULTS: The improvement of visual acuity up to 2 lines on the chart was found in 5 eyes (50%) after the surgery and six eyes (60%) showed improvement in macular edema. The complications after surgery were vitreous hemorrhage in 1 eye and submacular exuadates in 1 eye. CONCLUSIONS: Vitrectomy may be beneficial for patients with diabetic macular edema.

Compound nerve action potential (CNAP) of the mixed peripheral nerve is composed of A alpha beta, A delta, and C potentials. All components of CNAPs in the sciatic nerve were recorded by stimulating the tibial nerve of both control and lead-poisoned rats. Marked decrease of nerve conduction velocity and prolonged duration were found in A alpha beta and A delta fibers especially in large myelinated A alpha beta fibers. The amplitude decreased in A alpha beta potential, but the area did not change. In C potential produced by activation of unmyelinated fibers, nerve conduction velocity slightly decreased, but the amplitude and area did not significantly change. Pathologic correlates revealed prominent segmental demyelination with significant decrease of large myelinated fiber densities. Minimal axonal degeneration of unmyelinated fibers was present. We can conclude that electrophysiologic changes in the lead-poisoned rats correlate with pathologic changes in them.

Coronary artery steonosis can be effectively treated by non-operative percutaneous tansluminal coronaryangioplasty(PTCA). We performed PTCA in three patients with coronary artery stenosis, who were referred to thedepartment of radiology, from January to Dec. in 1985. The results were as follows; 1. The locations of coronaryartery stenosis were the proximal anterior descending branch of left coronary artery. 2. The number of stenoticlesions was single without calcium plaque in all three cases. 3. The extent of coronary artery disease is focal,under 2cm in length. 4. PTCA was performed successfully with satisfactory post-dilatation results in all cases. 5.Severe complications such as arterial intimal dissection, acute myocardial infarction, did not occurred. PTCA hasmany advantages over vascular surgery on surgical, economical, and psychological aspects.

OBJECTIVE: It was to analyze two failed arterial embolization cases in the treatment for pseudoaneurysm followed by D&C. METHODS: Two failure cases out of eight cases were gained in the transarterial embolization treatment for eight years.(1. 1. 1992 - 12. 31. 1999) To search for the factors of failure, we went through obstetrical history and biopsy. RESULTS: Eight cases of transarterial embolization were performed to the treatment for pseudoaneurysm appeared after undergoing D&C. Six cases were successfully treated without complications. However, laparotomy was done due to the continuous bleeding in the other two cases. According to tissue biopsy, they showed the cervical pregnancy in one case and placenta accreta in the other. CONCLUSION: Transarterial embolization is proved to be more preferable to operate in the treatment of pseudoaneurysm than laparotomy, and transarterial embolization therapy failure rate is higher in case of existing remnant villi than not.

Wiskott-Aldrich syndrome(WAS) is an X-linked recessive immunodeficiency characterized by thrombocytopenia with small platelet volume, eczema, and recurrent infections, and is also characterized by increased incidence of auto immune diseases and malignancies. The phenotype observed in this syndrome is caused by mutation in the Wiskott-Aldrich syndrome protein(WASP) gene localized to the proximal short arm of the X chromosome and recently isolated through positional cloning. The gene encodes a 502 amino acid protein, which contains 12 exons and spans 9 kb of genomic DNA. The function of the encoded protein is not well understood. The clinical diagnosis of WAS can be difficult and is usually confirmed by the detection of WASP gene mutations and the expression of WSAP in patient blood sample using genetic analysis. We reported a case of a 13-month old boy with WAS who was identified with the novel mutation in exon 2 of WASP gene by direct sequencing and the complete absence of WASP expression by immunoblotting.

PURPOSE: We conducted the immunoassay of pertussis according to ages, in order to evaluate protective immunity against pertussis in Korean populations. METHODS: Healthy subjects were enrolled at four university hospitals in Korea. The subjects were grouped as seven age groups (every 10 years). Antibodies against pertussis toxin (PT) in sera were measured by enzyme linked immunosorbent assay (ELISA) kits. Geometric mean concentrations (GMC) of antibodies and the ratios of the subjects with seroprotective antibody levels were determined. The subjects with antibody titers > or =24.0 EU/mL were considered to seroprotective as the manufacturer's protocol. RESULTS: Total 1,605 subjects (age: 2 months-65 years) participated in this study, and their GMC was 56.16+/-50.54 EU/mL. Among seven age groups, age group <11 year showed the highest GMC (64.78+/-53.24 EU/mL) (P<0.001). In the analysis of the ratios of the subjects with seroprotective antibody titers, 68.2% of the subjects were proven to seroprotective, and age group <11 year also showed the highest ratio (76.5%) (P<0.001). CONCLUSIONS: We found that adolescences or adults (age group > or =11 year) showed lower levels of antibody against pertussis and lower ratio of the subjects with seroprotective antibody titers than children (age group <11 year).

PURPOSE: Isolated local recurrence (ILR) after mastectomy is associated with increased risk of cancer-specific survival. This study evaluated the long-term survival and prognostic factors after ILR. METHODS: Between January 1988 and December 2004, 1,169 patients with early breast cancer (stage I or II) were treated with modified radical mastectomy at Kyungpook hospital. Retrospectively, 40 patients with isolated local recurrence (ILR) were found by medical records and we investigated their clinicopathologic factors and conducted analyses of prognostic factors, calculated overall survival, and relapse-free survival. RESULTS: The median follow-up times after initial operation and ILR were each 91 (range, 18~219) months and 40 (range, 1~205) months. There were 18 patients of 2nd recurrence and 15 expired by distant metastasis. The overall survivals at 5 years and 10 years after ILR were 65% and 49%. The relapse-free survivals at 5 years and 10 years after ILR were 54% and 29%. After 2nd recurrence, the mean survival time was 21 months and the 3-year overall survival rate was 21%. By univariate and multivariate analyses, the time interval between initial operation and ILR was only statistically significant independent prognostic factor of overall survival after ILR. The 10 year-overall survival rates of < or =24 months and >24 months to ILR were each 26% and 70%. There was no independent prognostic factor of relapse-free survival after ILR. CONCLUSION: For patients who developed isolated local recurrence after modified radical mastectomy for early breast cancer, shorter time interval to ILR is a poor prognostic factor of overall survival after ILR.

PURPOSE: Differentiated thyroid cancer is known to be one of cancers which have a favorable prognosis and long-term survival resulting from slow growth of tumor and late distant metastasis. Patients are nearly cured of thyroid cancer after first operation. But, some of those have high risk factors of recurrence. Practically it has been reported that 20% of those have recurrence of cancer and 50~60% of patients died of recurrence. We analyzed factors involving to recurrence after initial treatment, frequency and site of recurrence, disease-free interval, and results of treatment. Based on this information, we investigated therapeutics to decrease the rate of recurrence and prognostic factors to expect death. METHODS: 1803 patients were primarily operated for thyroid cancer in Kyungpook National University Hospital between 1985 and 2003. Among the cases, we reviewed the clinical records of 124 patients (6.9%) who had recurrent thyroid cancer. We analyzed the difference in frequency of recurrence on the basis of sex, age, histologic types, risk groups, and lymph node metastases when they had a first operation. The correlation between these factors and mortality rate was analyzed statistically by using Chi-square test and Fisher's exact probability test. RESULTS: Post-operative recurrence of thyroid cancer was highly observed in over 40 years old at first operation (8.4% vs. 4.9%), men (17.1% vs. 3.9%). Similarly, in the case of medullary or poorly-differentiated thyroid cancers, the groups of patients with high-risk (12.3% vs. 3.9%) or with lymph node metastases (13.5% vs. 3.7%) have high frequency of recurrence. Among the 124 patients, 53.3% cases have regional recurrence sites and 20.1% have local, 17.7% distant metastases, and 1.6% combined locoregional. The number of patients who died of recurrent cancer was 32 of 124 cases. Major cause of the death was distant metastases. In the case of 104 patients who had recurrent differentiated thyroid cancer, significant prognostic indicators of low survival rates are age greater than 45 years, neck dissection at second operation and distant metastases. CONCLUSION: In order to decrease the rate of local and regional recurrence in thyroid cancer, we conclude that complete resections of thyroid tissue and cervical lymph nodes have to be operated specially in the group with high-risk. Although adjacent organs are infiltrated, active treatment should be carried out. The treatment of most medullary or poorly-differentiated thyroid cancers which result in the death of distant metastases still remains to be studied.

BACKGROUND: TNF-alpha is related to the generation of lung fibrosis in patients with UIP. The precise mechanism leading to lung fibrosis by TNF-alpha is unknown. However, the activation of a transcription factor like AP-1(down stream of c-jun N-terminal kinase, JNK) by TNF-alpha may be related to the induction of fibrogenic cytokines like PDGF or IGF-I. Furthermore, JNK was reported to be activated in the radiation-in-duced lung fibrosis model. This study examined JNK activity in patients with UIP. METHODS: The expression of phosphorous JNK(p-JNK), macrophage/moncoyte specific markers, CD68, and cytokeratin was evaluated by immunohistochemical (IHC) staining of lung tissues from patients with UIP and lung cancer. An in vitro kinase assay was performed with alveolar macrophages obtained by a bronchollung cancer. An in vitro kinase assay was performed with alvolar macrophages obrtained by a bronchol avleolar lavage from patients with UIP and healthy persons as the control. RESULTS: The IHC stain showed that p-JNK is expressed in the almost all of the alveolar macrophages and smooth muscle cells in patients with UIP. In case of the normal areas of the lung from patients with lung cancer, the alveolar macrophages showed little p-JNK expression. Interestingly, increased JNK activity was not found in the in vitro kinase assay of the alveolar macrophages obtained from both patients with UIP and healthy persons as the control. Furthermore, 10 ng/ml of TNF-alpha failed to increase the JNK activity of the alveolar macrophages in both patients with UIP and healthy people. CONCLUSION: The JNK was activated constitutionally in patients with UIP. However, the role of JNK in the pathogenesis of lung fibrosis needs to be clarified.
