BACKGROUND: Diclofenac is a nonsteroidal anti-inflammatory drug widely used as adjuvants for postoperative pain management with opioid sparing effect. The effect of diclofenac on postoperative opioid analgesia of morphine and meperidine was evaluated in 180 women after cesarean section. METHODS: One hundred eighty parturients were randomly allocated to four groups and each group had 45 women. The parturients were given loading dose of morphine in M group and meperidine in D group using intravenous patient controlled analgesia (PCA) device for up to 48 hours when the parturients awoke and complained abdominal pain. The parturients received diclofenac 75 mg every 12 hours intramuscularly followed by loading dose of morphine in MV group and meperidine in DV group. We evaluated the postoperative opioid requirement, numerical rating pain score, delivery/demand ratio, patient's satisfaction and side effects including respiratory depression, itching, nausea, urinary retention and dizziness. RESULTS: Diclofenac decreased over 40% of morphine or meperidine requirement and also pain score at 1, 2, 3, 6, 12, 24 and 48 hours in the use of PCA morphine and at 6, 12 and 24 hours in the use of PCA meperidine. And the incidence of sedation and itching decreased in MV and DV group. CONCLUSION: We concluded that diclofenac as adjuvant of opioid for postoperative pain after cesarean section could decrease requirement of morphine and meperidine, increase pain relief and decrease sedation and itching.

Airway perforation is a rare but potentially fatal complication following laser surgery. A 66 years old man was admitted for surgery of tracheal stenosis. He had undergone 2 prior anesthesia for similar surgery and had diabetes mellitus due to chronic steroid therapy. 2 hours after surgery, tracheal perforation lead to pneumomediastinum, tension pneumothorax and perforation of innominate artery with potential risk to injury, which lies in the close proximity to perforation site of trachea. Arterial wall was so weak and fragile that it was difficult to repair the ruptured site. During the procedure, hemorrhage persisted and cardiac arrest developed. Immediate CPR(cardiopulmonary resuscitation) with internal cardiac massage was done but the patient did not recover. We believe that in patient with history of multiple operations, chronic steroid therapy and diabetes mellitus, the vascular structure of thin and fragile should be approached with greater caution when using CO2 laser during surgery.

PURPOSE: To report the clinical results from using absorbable suture materials instead of nonabsorbable materials which have been used more commonly to repair Achilles tendon. MATERIALS AND METHODS: We retrospectively reviewed 21 cases of acute Achilles tendon rupture, treated surgically from 2004 to 2011. Mean follow-up period is 6 months. We repaired Achilles tendon using size 1 Vicryl (Polyglactin 910, Ethicon) for core suture and size 3-0 Vicryl for epitendinous suture. At three months after surgery, we evaluated clinical results with single heel raise height by centimeters, differences of calf circumference and passive range of motion of ankle joint, compared to contralateral side. Also we recorded clinical results with subjective satisfaction grades. RESULTS: At three months after surgery, 20 of 21 patients were able to perform single heel raise over 5 cm in height. Calf circumference differences were less than 1 cm in 12 cases, between 1 cm to 3 cm in 5 cases, more than 3 cm in 4 cases. There was no difference in range of passive motion in 19 cases. All patients satisfied with daily activity except 2 cases with mild discomfort. There was no complication such as rerupture, elongation or infection. CONCLUSION: We experienced excellent clinical results from repairing Achilles tendon with using absorbable suture materials in terms of functional outcomes and patient's satisfaction without any complication. So we may consider using absorbable suture materials instead of nonabsorbable materials to repair Achilles tendon.

PURPOSE: The purpose of this study was to analyze the expression of inducible nitric oxide synthases (iNOS), tissue inhibitors of metalloproteinase (TIMP)-3, and TIMP-4 in the gingival tissues of periodontal patients with or without type 2 diabetes mellitus (DM). METHODS: Depending on the patient's systemic condition and clinical criteria of the gingiva, each gingival sample was classified into one of three groups. Sixteen clinically, systemically healthy patients (group 1), 16 periodontal patients (group 2), and 16 periodontal patients with DM (group 3) were included. Tissue samples in each group were collected, prepared, and analyzed by western blotting. Quantification of the relative amount of TIMP-3, TIMP-4, and iNOS was performed. RESULTS: The expression levels of iNOS and TIMP-3 both increased in group 1, group 2, and group 3 in increasing order, and were significantly higher in both group 2 and group 3 as compared to group 1 (P<0.05). The expression levels of TIMP-4 increased in the same order, but significantly increased in group 2 as compared to group 1, in group 3 as compared to group 1, and group 3 as compared to group 2 (P<0.05). CONCLUSIONS: This study demonstrated that iNOS, TIMP-3, and TIMP-4 might be involved in the progression of periodontal inflammation associated with type 2 DM. It is thought that further study of these factors can be applied practically for the diagnosis and control of periodontitis in diabetics.

"BACKGROUND: Between 80 to 85% of patients with hyperparathyroidsm have a solitary adenoma of the parathyroid glands and another 15% have a parathyroid hyperplasia. Preoperative localization of the parathyoid glands is generally accepted as warranted in patients who have failed an initial attempt at parathyroidectomy, ectopic locations and inexperienced surgeons. Different imaging techniques have been used for detection of abnormal parathyroid glands such as high resolution ultrasonography, computerized tomography, arteriography, venous sampling or magnetic resonance imaging and 201Tl/99mTc subtraction scintigraphy. But these methods have had varying rates of success, with low specificity and low sensitivity. Among the several different techniques available for parathyroid radionuclide imaging, the most common is the use of a dualradioisotope procedure combining of Tl with Tc. However, there are some controversies regarding the optimal technical aspects of this procedure, including the relative amount of injected dose of radiotracers, failed detection for small sized and deeper cervical located parathyroids, and not easy procedures. Recently, double phase Tc-sestamibi scintigraphy would be useful to solve these technical limitations, more convenient and have higher sensitivities. The purpose of this study was to compare the diagnostic accuracy of 99mTc-sestamibi with 201Tl/ 99mTc subtraction scintigraphy in the localization of hyperparathyroidism. METHODS: 9 patients with hyperparathyroidism underwent preoperative evaluation with double phase 99mTc-sestamibi scintigraphy and 201Tl/99mTc subtraction scintigraphy for attempted localization of abnormal parathyroid glands and surgical explorations. Imaging results were compared to surgical findings. RESULTS: Of 9 patients, 7 had a solitary parathyroid adenoma, 1 had a carcinoma and 1 had parathyroid hyperplasia. The 201Tl/99mTc subtraction scintigraphy preoperatively localized 8 of 9 patients(sensitivity: S9%) and 99mTc-sestamibi scintigraphy correctly localized all lesions for a sensitivity of 100%. In one case, 201Tl/99mTc subtraction scan show only a hot uptake at left upper parathyroid area, but 99mTc-sestamibi scan was shown the three site of hot uptake at left upper, both inferior parathyroid area. CONCLUSION: In patients with hyperparathyoridism, 99mTc-sestamibi scintigraphy may be used as the single imaging technique as it show a very high sensitivity and specificity in the preoperative localization of pathological parathyroid glands.

PURPOSE: The aim of this study is to evaluate the correlation between the location of the plate and the incidence of clavicular hypoesthesia and the clinical features of patients with clavicular hypoesthesia after open reduction and internal fixation of clavicular midshaft fractures. MATERIALS AND METHODS: Seventy-eight patients who underwent open reduction and plate fixation for clavicle midshaft fractures between March 2013 and October 2014 were assessed for eligibility. The total clavicular length (A), the distance to the medial end of the plate from the sternoclavicular joint (B), and the distance to the lateral end of the plate from the sternoclavicular joint (C) were measured. Correlation between the location of the clavicular plate and the incidence of clavicular hypoesthesia was evaluated. In addition, the severity, and recovery of hypoesthesia were evaluated. Patient satisfaction, pain visual analogue scale were evaluated regarding hypoesthesia. RESULTS: The incidence of hypoesthesia was 32.1% (25/78 patients). No correlation was observed with respect to the location of the clavicular plate and the incidence of clavicular hypoesthesia (p=0.666 at the medial end, p=0.369 at the lateral end). Recovery from hypoesthesia was observed in 23 out of 25 patients (p=0.008). Patient satisfaction and pain showed negative correlation with the incidence of hypoesthesia (p=0.002 and p=0.022). CONCLUSION: There was no correlation between clavicular hypoesthesia and the plate location. Although most cases of hypoesthesia were recovered, we should try to avoid hypoesthesia due to the negative 'correlation' with patient satisfaction and pain.

BACKGROUND: Ectopic thyroid gland is relatively rare condition and a developmental anomaly characterized by an aggregated of thyroid tissue in the midline anywhere from the base of the tongue to the mediastinum. The role of ectopic thyroid in the pathogenesis of non-goitrous sporadic cretinism and primary hypothyroidism has been emphasized. 19 cases of ectopic thyroid for 12 years was presented with Tc-pertechnetate or radioactive iodine, which were diagnosed by scintigraphy. METHODS: We wish to report these 19 cases and 12 cases of brief review of literatures on the incidence, etiology and development, symptomatology, diagnosis and treatment of ectopic thyroid gland was done. RESULTS: The most frequent incidental age was between the age 1 year and 29 years. And the frequency of ectopic thyroid was about 7 times more common in female(27 cases) than in male(4 cases). The location of ectopic thyroid were found to be lingual in 18 cases, sublingual in 9 cases, prelaryngeal in 1 case, and combine with lingual and sublingual in 3 cases. In chief complaints, palpable mass was most common and there were foreign body sensation on throat, dysphagia, dysphonia, and hoarseness. In 15 cases of hypothyroidism, l2 cases were taken thyroid hormone replacement therapy, 1 case was removed ectopic thyroid gland. In 2 of 10 cases of euthyroidism, replacement of thyroid hormone were done and 2 cases were removed ectopic thyroid gland, in 6 cases of unknown thyroid function, 1 case was removed ectopic thyroid gland and 131I therapy was done in 1 case, and others were observed with following up thyroid function test. CONCLUSION: These results suggest that the long terms thyroid function test, thyroglossal duct eyst and malignant change in ectopic thyroid tissue when finding the ectopic thyroid in thyroid scintigraphy were recommended highly.

PURPOSE: The purpose of this study was to to analyze the effect of Type 2 diabetes on tooth mortality, implant treatment and prosthetic status. MATERIALS AND METHODS: 275 Type 2 diabetics and 300 non-diabetics, aged 40-80 years were selected for analysis. The assessment of number of teeth, missing teeth, fixed prostheses (bridge pontics), implants using panoramic radiographs and dental records were carried out. RESULTS: Diabetes mellitus (DM) patients had a higher number of missing teeth (P<.05) and placed implants (P=.074), age (P<.05), male gender percentage (P=.042), smoker percentage (P<.05) than non-DM patients. In univariate analysis, the patients in older group showed significantly higher number of tooth loss rate at the first dental examination than the patients in younger group. Tooth loss rate of smokers did not show higher value than that of non-smokers. When multiple variables including DM, age, smoking, gender were considered together, diabetics and older group patients showed significantly higher tooth loss rate at the first dental examination than non-diabetics and younger group patients, respectively. Smokers and male group did not show a significant difference than non-smokers and female group, respectively. CONCLUSION: Tooth mortality and implant treatment rate were significantly higher in the DM group as indicated by univariate and multivariate logistic regression analysis. Old age groups showed significantly higher odds ratios and tooth loss rate. As diabetics showed the higher tooth loss rate than non-diabetics, diabetics also had more implant restorations than non-diabetics.

The purpose of this study is to correlate the material properties of TiZr alloy material (Roxolid) and the mechanical strength of the implant fixture (BLT) through the maximum compressive load test and the fatigue test. Implant samples were purchased with BLT (Roxolid, Straumann, Switzerland) and Octa1 (cold-worked, Megagen Implant, Korea) fixtures made of two materials (TiZr and cold-worked Ti Grade 4). After the maximum compressive load test, the test specimens were analyzed with a optical microscope to confirm the fracture pattern. After the fatigue test, the samples that passed 5 million cycles were analyzed for the precision fit using a scanning electron microscope. Data were analyzed using Student's t-test (α=0.05). In the compressive load test, the small diameter (3.3 mm) implants with the same length and the common diameter (4.1 mm) implants had fracture or bending regardless of the material in both the test and control groups. The fatigue load showed the same results without significance and the gap between the fixture and abutment interface was within 10 µm in both the test and control groups in the precision fit test. There was no statistically significant difference in the maximum compressive load and fatigue test for the comparison of mechanical strength between two systems (BLT vs. Octa1) with same diameter and length, similar shapes and connections.
