Objectives : The purpose of this study was clinical observation about sensorineural hearing loss compare with acupucture treatment and assessments of prognotic factors. Methods : This study was clinical observation about sensorineural hearing loss cases. for diagnosing in these cases, pure tone audiometry was used. The treatment, acupuncture was used. Results : Three patients(37.5%) remarkably improved, one patient(12.5%), slightly improved, four patients(50%), no change. Conclusions : These results suggest that the prognosis by age and initial hearing threshold was significant. The treatment on sensorineural hearing loss considered that bone condution improved.

Objective : The purposes of this study are to evaluate the efficacy of en bloc open-door laminoplasty and to investigate the validity of various factors as prognotic indicators in patients with multisegmental spondylotic myelopathy and ossification of posterior longitudinal ligament[OPLL]. Methods : The authors reviewed 43 cases in whom laminoplasty were performed for cervical myelopathy between January 2000 and December 2002. Clinical symptoms and results were evaluated using the Japanese Orthopaedic Association[JOA] scale. The recovery rate was calculated and then assessed for prognostic factors such as preoperative JOA scores, ages, history of previous trauma, duration of symptoms and signal change in cord on T2-weighted magnetic resonance Image. Results : In cervical stenosis, canal widening of antero-posterior diameter and dimension after laminoplasty is 4.16mm, $87.43mm^2$ and in OPLL is 6.20mm, $117.61mm^2$. In all cases there wasn't neurologic deterioration, mild postoperative complications developed in seven cases. Four patient had a limitation of range of neck motion and the other one showed kyphotic change and another two showed C5 radiculopathy. The recovery rate of JOA score in cervical stenosis and OPLL was 62% and 68% respectively. Duration of symptoms, the severity[preoperative JOA score], and signal change in cord on T2-weighted magnetic resonance image had close relationship to the clinical outcomes. Conclusion : Unilateral en bloc laminoplasty is simultaneous expansile and decompressive method. And preoperative JOA score, symptom duration and high signal intensity on T2-weighted magnetic resonance image can be used to predict prognosis.

Objective : The purpose of the study was to identify expression profiling of miRNAs associated with cancers after treating allergen-removed Rhus Verniciflua Stokes and allergen-removed Rhus Verniciflua Stokes fumigaed Angelica gigas on leukemia cell lines. Methods : miRNA expression has been analyzed using miRNA array method through denaturation and hybridization after isolating the total RNA from leukemic cell line treated with 100 ㎍/㎖ of aRVS and aRVS-A each. Microarray expressions were interpreted as 'significant' on miRNAs when decreased less than 0.5 fold or increased more than 1.5 fold compared with the control group. Results : Among 158 miRNAs in total, 32 miRNAs were significantly presented in miRNAs expression. miRNA has been activated with a variety of genes for predicted targets, and the overexpressed miRNAs were categorized according to proliferation and metastasis of cancer in this study. The findings were reported that seven miRNAs (let-7b, miR-193a-5p, 296-3p, 26a, 22, 124a, 92b) showed significant expressions on proliferation and growth, seven miRNAs (miR-193a-5p, 26a, 200c, 183, 124a, 198, 210) presented meaningful expressions on invasion and metastasis, two miRNAs (let-7b, miR-210) were highly expressed on angiogenesis, five miRNAs (let-7b, miR-26a, 181d, 181c, 296-5p) related with apoptosis, and six miRNAs (let-7b, miR-200c, 183, 370, 124a, 191) were associated with prognosis of cancer and early diagnostic factors for cancer. Conclusion : The mechanism of miRNA takes a role in diagnosis, treatment, and prognotic factors for cancer as well. This study suggested that further detailed research on overexpression of specific miRNA should be carried out continuously in the future.

Thyroid carcinoma ranks low in incidence and as a cause of death when compared to carcinomas arising in the other site. With adequate surgical treatment, the prognosis of operable thyroid carcinoma is good. However, the extent of surgical resection in treatment of thyroid cancer remains still controversy. The aim of this study was to assess the results of thyroid cancer patients treated surgically and to analyze the prognostic factors affecting survival and to improve the survival rate. We retrospectively analyzed the outcome of a total of 278 thyroid cancer patients treated surgically at Inje University Paik Hospital from 1980 to 1995 and followed for 1 to 16 years. There were man in 47 and woman in 231 patients with age range of 14 to 79 years(mean 42 years). Histopathologic findings were papillary carcinoma in 233, follicular carcinoma in 33, mixed carcinoma in 7, medullary carcinoma in 2, and undifferentiated carcinoma in 3 patients, respectively. Operative procedures were unilateral lobectomy in 111, subtotal thyroidectomy in 100, and total thyroidectomy in 67 patients. Central node dissection was performed in 92, modified neck disseciton in 62, radical neck dissection in 28, and no node dissection in 96 patients. Thyroid hormone was administered for the period of 3 to 5 years to suppress endogenous TSH production. Overall 5-year survival rate according to Kaplan-Meier method was 91.1%. Independently, significant factors affecting the prognosis were age at diagnosis, tumor size, pathologic type, tumor stage, lymph node metastasis, angioinvasion, extrathyroidal extension, and 'risk' group category. but, the prognosis were not influenced by sex and capsular invasion. Patients at low risk or with small size carcinomas had long survival over 5 years with only lobectomy. Lymph node dissection was carried out with a limited type in no jugular metastasis, radical neck dissection was performed only therapeutically in proved jugular node metastasis. Fifteen patients were dead of tumor recurrence after surviving for three months to two and half years, and the cause of death was local recurrence in nine, bone metastasis in four and lung metastasis in two patients. In conclusion, more extensive surgery including total thyroidecotmy and systematic compartment-oriented dissection of the lymph node metastases in patient at high-risk group will results in better survival and lower recurrence rate.

Purpose: This study was conducted to determine the incidence, causative pathogens, risk factors and mortality for early onset sepsis in the first three days in very low birth weight infants. Methods: The medical records of 1,124 very low birth weight infants admitted to the neonatal intensive care unit of Samsung Medical Center between November 1994 and December 2008 were retrospectively reviewed. The incidence, causative pathogens, risk factors, and mortality for early onset sepsis in the first 3 days of life in very low birth weight infants were evaluated. Results: Early onset sepsis, as confirmed by positive blood cultures, was present in 17 of 1,124 infants (1.5%). Sixty-four percent of the isolated pathogens were gram-positive bacteria and 35% of the isolated pathogens were gram-negative bacteria. The dominant pathogens of early onset sepsis included Staphylococcus aureus (23.5%), Esherichia coli (23.5%), and Enterococcus (17.6%). Vaginal delivery (adjusted odds ratio [OR], 3.7; 95% confidence interval [CI], 1.3-10.3; P=0.01) was associated with early onset sepsis. The overall mortality (adjusted hazard ratio, 3.0; 95% CI, 1.4-6.5; adjusted P=0.0039) and mortality within 72 hours of life (adjusted hazard ratio, 6.5; 95% CI, 2.2-18.9; adjusted P=0.0005) of infants with early onset sepsis were higher than that of uninfected infants. Conclusion: Early onset sepsis remains an uncommon, but potentially lethal problem among very low birth weight infants. Knowledge of the likely causative organisms and risk factors for early onset sepsis can aid in instituting prompt and appropriate therapy, in order to minimize mortality.
