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: 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.

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.

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.

An encepholocele is defined as a herniation of cranial contents through a defect in the skull. Encephaloceles are classified accroding to their contents and location. Encephalocele is a useful general term to refer to common features of the various forms of anomaly, but considerable differences exist in the pathology, treatment and prognosis of encephaloceles at each anatomical location. Improved neuroimaging facilities, especially MRI, make it easy not only to detect the encephalocele including its contents and location, but also to get preoperative informations. We have reviewed a total of 22 patients with encephalocele whom we have experienced from 1986, July to 1990, June. Twelve were at occipital location, six at cranial vault, three at cranial base, one at frontoethmoidal location. The size of cranium bifidum and herniating sac of the cranial vault and occipital location is larger than that of frontobasal location. The incidence of associated hydrocephalus is in order of occipital, cranial vault, frontobasal form, and its prognosis is also better in frontobasal form than in occipital of cranial vault form.

Far lateral disc herniation(FLDH) with compression of the nerve root as it exits through the foramen has been a recognized entity for a number of years. Failure to diagonose and precisely localize these herniations can lead to unsuccessful surgical exploration or exploration of the innocent interspace. If these herniation are diagnosed, they often cannot be adequately exposed by the classic minline hemilaminectomy approach. A partial or complete unilateral facetectomy to expose these herniations can lead to vertebral instability or contribute to continued postoperative back pain. The authors present 5 patients who were diagnosed as having far lateral lumbar disc herniations from 1988 to 1990. Two of these were at L4-5 level, two at L5-S1 level and one at L3-4 level and all were over 60 years old. High resolution CT scan appeared to be the best study and the paramedian muscle splitting microsurgical approach, done in 3 cases, was found to be the most direct and favorable anatomical route to FLDH for vertebral stability and minimal postoperative back pain.

Multiple primary cancer is defined as the case of primary malignant tumors of different histologic origins each other in one person, The incidence of multiple primary cancer has been increasing recently due to more developed diagnostie procedure and long survival of cancer patients. In esophageal cancer patients, comibined prevalence of other malignancy is rela tively high. We have experienced three cases of gastric adenocarcinoma with esophageal squamous cell carcinoma and report these cases with a review of literatures.

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.

Lymphocytic interstitial pneumonia(LIP) is characterized by a massive infiltration of the interstitium of the lung by mature lymphocytes, plasma cells and reticuloendothelial cells. LIP may be associated with autoimmune diseases including Sjogrens syndrome, SLE, myasthenia gravis, pernicious anemia, autoimmune hemolytic anemia, and HIV or an EB virus infection. There is a possibility of LIP progressing to a pulmonary or systemic lymphoma. The therapeutic response to corticosteroids and/or immunosuppressive drugs varies. Here we report a case of LIP that was diagnosed by an open lung biopsy and clonality study. The patient was a 36 year-old man without antuimmune disease or HIV infection. He was admitted as a result of severe hypoxemia showing PaO2 of 48.3 mmHg. The patient was treated with corticosteroids after the diagnosis and had fully recovered without a sequalae or relapse.
