Backgrounds: Thyroid hormones play a fundamental role in the initiation and maintenance of somatic growth in mammalian species, and the insulin-like growth factors(IGFs) occupy a position of central importance in the growth of all tissues. To evaluate the changes in serum insulin-like growth factor-I(IGF-I) and insulin-like growth factor binding proteins in hyperthyroid and hypothyroid patients, sera was obtained from 19 hyperthyroid patients, 9 hypothyroid patients, and 10 healthy volunteers. Methods: IGF-I concentration was determined by radioimmunoassay, and changes in IGFBPs were assesed by Western Ligand Blotting. To evaluate the binding pattern of IGF-I & IGFBPs, autoradiographs were obtained. Results & Conclusion: IGF-I levels were increased significantly in hyperthyroid patients(mean ±SE, 267.88±9.80 ng/ml, p<0.05) and decreased significantly in hypothyroid patients(154.81±1.43 ng/ml, p<0.01) compaired to healthy control group(209.45±.60 ng/ml). Autoradiograph of serum IGFBPs from patients with hyperthyroidism and hypothyroidism did not show any change in the intensity of IGFBP-3 bands(40-45 KD) and IGFBP-1 bands, but in hyperthyroid patients, it showed increased intensity of IGFBP-2 band compared to healthy control group and hypothyroid patients.

OBJECTIVE: The purpose of this study was to evaluate the outcome and safety of vaginal delivery after previous cesarean birth. METHODS: This study was based on 303 cases of delivery with previous cesarean birth at Masan, Fatima Hospital from May, 1997 to April, 1998. Among them, 62 cases had performed trial of labor. We had made a comparison between elective repeat section group and trial of labor group by analizing the frequency, successful rate, maternal morbidity, perinatal morbidity and mortality. RESULTS: Among 303 cases with previous cesarean birth, trial of labor was done in 62 cases(20.5%). Among trial of labor group, vaginal delivery was done in 54 cases (87.1%) and repeat section was done in 8 cases(12.9%). Indications for elective repea section before the onset of labor were refuse trial of labor(51.9%), request for tubal ligation(17.4%), and previous section > or =2(7.5%), etc. The successful rate of vaginal delivery according to indication for previous cesarean birth was 85.0%(17/20) in the cases of dystocia and 88.1%(37/42) in the cases except dystocia. The successful rate was not influenced by the indication for previous cesarean birth(P>0.05). There were no maternal death or uterine rupture in the cases of trial of labor. There were no significant difference between elective repeat section group and trial of labor group in maternal morbidity, perinatal morbidity and mortality(P>0.05). CONCLUSION: Under strict indications, vaginal delivery subsequent to cesarean birth may be safe, and can reduce the rate of cesarean section that was increased constantly.

OBJECTIVE: To investigate the feasibility of C1 lateral mass screw and C2 pedicle screw with polyaxial screw and rod system supplemented with miniplate for interlaminar fusion to treat various atlantoaxial instabilities. METHODS: After posterior atlantoaxial fixation with lateral mass screw in the atlas and pedicle screw in the axis, we used 2 miniplates to fixate interlaminar iliac bone graft instead of sublaminar wiring. We performed this procedure in thirteen patients who had atlantoaxial instabilities and retrospectively evaluated the bone fusion rate and complications. RESULTS: By using this method, we have achieved excellent bone fusion comparing with the result of other methods without any complications related to this procedure. CONCLUSION: C1 lateral mass screw and C2 pedicle screw with polyaxial screw and rod system supplemented with miniplate for interlaminar fusion may be an efficient alternative method to treat various atlantoaxial instabilities.

OBJECTIVES: Manganese is cytotoxic to the central nervous system including basal ganglia. Its toxic mechanism is related to oxidative stress, mediated by toxic free radicals but is specultives. In the present study, we have investigated to manifest apoptosis in manganese-induced cytotoxicity in primary neuronal cell culture of rat basal ganglia. METHOD: To detect apoptotic neuronal cells were stained by the terminal deoxynu-cleotide(TdT)-mediated dUTP nick end-labelling(TUNEL) method and apoptotic changes in nuclei of neurons were observed by electron microscopy. RESULTS: We showed that TUNEL immunostain showed brownish signal in the nuclei of apoptotic cells and the proportions of apoptotic cells in Manganese treatment groups were more higher than controls. On transmission electron microscopy, there were chromatine condensation with margination toward nuclear membrane and condensation of cytoplasm in the treated with luM MnC1, for 48 hours in a basal ganglia neurons. Apoptotic bodies were found and consisted of semilunar-like condensed nuclei with relatively intact cytoplasmic organelles. CONCLUSIONS: Apoptosis appears to be one mechanism in the manganese-induced neuronal cell death. Manganese intoxication is a convenient model for apoptosis study.

PURPOSE: The ratio of serum leptin to adiponectin (L/A ratio) could be used as a marker for insulin resistance. However, few prospective studies have investigated the impact of L/A ratio on improvement of metabolic components in high-risk individuals with metabolic syndrome. We examined the association between L/A ratio and the regression of metabolic syndrome in a population-based longitudinal study. MATERIALS AND METHODS: A total of 1017 subjects (431 men and 586 women) with metabolic syndrome at baseline (2005–2008) were examined and followed (2008–2011). Baseline serum levels of leptin and adiponectin were analyzed by radioimmunoassay. Area under the receiver operating characteristics curve (AUROC) analyses were used to assess the predictive ability of L/A ratio for the regression of metabolic syndrome. RESULTS: During an average of 2.8 years of follow-up, metabolic syndrome disappeared in 142 men (32.9%) and 196 women (33.4%). After multivariable adjustment, the odds ratios (95% confidence interval) for regression of metabolic syndrome in comparisons of the lowest to the highest tertiles of L/A ratio were 1.84 (1.02–3.31) in men and 2.32 (1.37–3.91) in women. In AUROC analyses, L/A ratio had a greater predictive power than serum adiponectin for the regression of metabolic syndrome in both men (p=0.024) and women (p=0.019). CONCLUSION: Low L/A ratio is a predictor for the regression of metabolic syndrome. The L/A ratio could be a useful clinical marker for management of high-risk individuals with metabolic syndrome.

A healthy 72-year-old male was referred to the emergency department (ED) for removal of a foreign body (FB) in the right bronchi from a local medical clinic. The FB was a dental part measuring 5×15 mm in size, which had been accidently aspirated into the lung during a dental procedure. On arrival at the ED, he only complained of mild chest discomfort, and there were no abnormal findings in on physical examination. ED physicians prepared bronchoscopic FB removal while the patient rested in bed. During the wait for bronchoscopy, the patient felt discomfort in the chest and epigastric area, and then he coughed forcefully and at the same time, epigastric thrust was performed with his fist. After several strong coughs with epigastric thrusts, the FB was expelled from his mouth. Chest roentgenogram showed no FB, and the patient was discharged from the ED with no complications. Bronchoscopy has been the only treatment option for bronchoscopic FB, and self-removal of FB is rare. This case report may be helpful to understanding a possible mechanism of self-clearance of FB in some healthy adult patients with a small-sized endobronchial FB.

Bisphosphonate-related osteonecrosis of the jaw (BRONJ) is a side effect of Bisphosphonates (BPs) use. These days, oral bisphosphonates are normally prescribed to treat osteoporosis. Intravenous BPs are used extensively to treat osteolytic bone lesions related to multiplemyeloma and bone metastasis of solid cancers, breast cancer or prostate cancer. As the prescription of BPs is universalized and the number of people treated with BPs is increasing, an accurate understanding and proper management of BRONJ are required. The aim of this study was to improve the clinicians'understanding of BRONJ by reviewing the literature. To achieve this, this paper introduces case reports as well as the current concept of BRONJ based on the 2009 updates by American Association of Oral and Maxillofacial (AAOMS) including the definition, epidemiology, etiology, diagnosis, treatment and prevention of BRONJ.

PURPOSE: This randomized, controlled, double-blind study was designed to determine the optimal dose of remifentanil for preventing complications associated with the removal of a laryngeal mask airway (LMA) without delaying emergence. MATERIALS AND METHODS: This study randomly assigned 128 patients to remifentanil effect-site concentrations (Ce) of 0 ng/mL (group R0), 0.5 ng/mL (group R0.5), 1.0 ng/mL (group R1.0), and 1.5 ng/mL (group R1.5) during emergence. The emergence and recovery profiles were recorded. Adverse events such as coughing, airway obstruction, breath-holding, agitation, desaturation, nausea, and vomiting were also evaluated. RESULTS: The number of patients with respiratory complications such as coughing and breath-holding was significantly lower in the R1.0 and R1.5 groups than in the R0 group (p<0.05). Emergence agitation also decreased in the R1.0 and R1.5 groups (p<0.0083). The time to LMA removal was significantly longer in the R1.5 group than in the other groups (p<0.05). CONCLUSION: Maintaining a remifentanil Ce of 1.0 ng/mL during emergence may suppress adverse events such as coughing, breath-holding, and agitation following the removal of LMA without delayed awakening.
