BACKGROUND: Postoperative sore throat (POST) is considered a usual complication after tracheal intubation, especially, thyroid surgery. Gabapentin is a widely studied multimodal perioperative drug, which can be used to treat acute postoperative pain. The primary endpoints of this study was a reduction of the incidence of POST at rest and during the swallowing movements after thyroid surgery. And the second endpoints was a reduction of the intensity of the POST after thyroid surgery. METHODS: Seventy-one patients that underwent elective thyroid surgery received either gabapentin (Neurontin(TM) 600 mg) or placebo, orally, one hour before anesthesia. The VAS scores and incidences of POST and adverse effects were determined at 1 hr, 6 hr, 12 hr, and 24 hr after surgery at rest and during swallowing movement. RESULTS: The gabapentin group (N = 36) showed a lower incidence of POST than the placebo group (N = 35) (47% vs. 78%, P = 0.038), and had significant lower VAS score at 6 and 24 hours after surgery in the resting state. However, during the movement, no intergroup differences were found in terms of the incidence of POST (83% vs. 91%, P = 0.305) or VAS score. Furthermore, no significant difference was observed between the two groups, in adverse effects. CONCLUSIONS: Gabapentin (Neurontin(TM) 600 mg) administered 1 hr before anesthesia reduced the intensity and incidence of POST during the resting state without a significant adverse event, during the 24 hr after thyroid surgery. However, gabapentin did not reduce the intensity and incidence of POST during the swallowing movement.

OBJECTIVE: We investigated the norepinephrine transporter (NET) expression in normal and pre-eclamptic placentas and analyzed the invasion activity of trophoblastic cells based on norepinephrine (NE)-NET regulation. METHODS: NET and NE expression levels were examined by western blot and enzyme-linked immunosorbent assay, respectively. Trophoblast invasion activity, depending on NE-NET regulation, was determined by NET-small interfering RNA (siRNA) and NET transfection into the human extravillous trophoblast cells with or without NE treatment and invasion rates were analyzed by zymography and an invasion assay. RESULTS: NET mRNA was expressed at a low level in pre-eclamptic placentas compared with normal placentas and NE concentration in maternal plasma increased significantly in pre-eclamptic women compared to normal pregnant women (p<0.05). NET gene upregulation and NE treatment stimulated trophoblast cell invasion up to 2.5-fold (p<0.05) by stimulating matrix metalloproteinase-9 activity via the phosphoinositol-3-kinase/AKT signaling pathway, whereas NET-siRNA with NE treatment reduced invasion rates. CONCLUSION: NET expression is reduced by inadequate regulation of NE levels during placental development. This suggests that a complementary balance between NET and NE regulates trophoblast cell invasion activities during placental development.

PURPOSE: E-cadherin (ECD) plays a pivotal role in integrating the normal tissue architecture and the suppression of cancer invasion, including stomach cancer. The epidemiology of stomach cancers is noticeably different according to the site of the index tumor, even though the stomach cancers all have similar gross shapes. In this study, the relation between the expression of ECD, along with the clinicopathologic parameters and recurrence or survival, were investigated for patients with gastric adenocarcinoma according to the tumor location. METHODS: We examined formalin-fixed, paraffin-embedded archival tissues from 50 surgically resectable gastric adenocarcinomas, which were grouped by the index tumor site as follows: distal (antrum) versus proximal (mid and upper body). To elucidate the correlation between the ECD expression and the site of the stomach cancer with the other clinicopathologic factors, we examined the ECD tissue status via performing immunohistochemistry. To compare the rates of recurrence and survival among subgroups, the patients were followed up for an average of 42 months. RESULTS: Among the 50 tumors examined, 28 (56%) tumors showed various degrees of a ECD expression. The gender, age, size, depth of invasion, lymph node metastasis, stage, lymphatic invasion and vascular invasion were not related with the ECD expression. The Lauren classification was cor-related with the ECD expression in the mid and upper body stomach cancer, but not in the antral stomach cancer (P=0.042). The expression of ECD was not related with the survival rate (P=0.223). There was no significant difference in the recurrence rate between the subgroups with and without an abnormal expression of ECD (P=0.588). CONCLUSION: For the mid and upper body stomach cancer, the expression of E-cadherin correlated with the diffuse type of cancer, according to the Lauren classification, but not with the survival rate.

Amlodipine, a calcium channel blocker (CCB) belonging to the group of dihydropyridines, is characterized by a slower onset of action (6-8h), a longer duration of action (24-72h), a greater vascular, cardiac effect, and hyperglycemia. Case of intoxication with 300 mg of amlodipine in a 69-year-old female patient and with 450 mg of amlodipine and 120 mg of glimepride in a 64-year-old female patient caused severe hypotension and hyperglycemia. They were initially treated with fluids, dopamine and norepinephrine, but these therapy were ineffective. Then, the patients were given a bolus injection of insulin and continuous infusion of insulin. The former patient's hyperglycemia was not controlled. She expired in 47 hours. The latter one's hyperglycemia was controlled and then her hypotension improved. In conclusion, it is suggested that hyperinsulinemia-euglycemia therapy be considered as a first-line therapy in calcium channel blocker intoxication.

OBJECTIVES: This study was carried out to estimate the prevalence of isocyanate-induced occupational asthma in toluene diisocyanate (TDI) exposed workers. METHODS: We examined 170 workers who had been directly exposed to TDI through a medical questionnaire, physical examination, and pulmonary function test. Based on screening examination, workers with suspected occupational asthma were selected for further evaluation such as methacholine and TDI challenge tests. RESULTS: Eleven (6.9%) among 170 workers complained of symptoms of occupational asthma, and 7 among these 11 symptomatic workers showed positive responses to the methacholine challenge test (4.1%). One spray painter was confirmed as having the TDI induced occupational asthma following a positive response to TDI challenge test. CONCLUSIONS: The prevalence of TDI-induced asthma was at 0.58% was lower than that for former studies (2-20%). Improved workplace environment, lower level of TDI exposure compared to the past, and the healthy workers effect may have contributed to this low rate of asthma prevalence in workers with TDI exposure.

OBJECTIVES: This study was carried out to estimate the magnitude of occupational asthma and to determine its characteristics. METHODS: We collected and analyzed 121 cases of occupational asthma reported by a surveillance system in Incheon for 5 years. The cases were classified according to industry and causing gent. We attached the data to worker's compensation records to establish the degree of agreement between the two sources. RESULTS: The industry of musical instrument manufacture was the most common (31 cases, 25.6%), followed by furniture manufacture, dye making, and machinery manufacture. TDI was the most common causing agents (52 cases, 43%), followed by reactive dye, wood dust, and organic dust. There was poor agreement with the worker's compensation records (2 cases, 8%). CONCLUSIONS: TDI and reactive dyes were the major materials causing occupational asthma. Most cases reported by the surveillance system were not applied to the worker's compensation system. Therefore, the surveillance system should be used to estimate the magnitude of occupational asthma and to determine its characteristics.

We studied the sex different nicotine effect on evoked population spike amplitudes (ePSA) and connexin (Cx) expression in the hippocampus CA1 area of gerbils. Acute doses of nicotine bitartrate (0.5 mg/kg: NT-0.5) slightly reduced ePSA in males but markedly augmented that in females. Acute NT (5.0 mg/kg) markedly increased the ePSA in all gerbils. Unlike acute NT-0.5, repeated NT-0.5 injection (twice a day for 7 days) significantly increased the ePSA in males and slightly affected the NT-0.5 effect in females. The Cx36 and Cx43 expression levels as well as Cx expressing neuronal populations were significantly increased by repeated NT-0.5 in in both male and female gerbils, and particularly, Cx43 expression was somewhat prominent in females. These results demonstrated a sex difference with respect to the nicotine effect on hippocampal bisynaptic excitability, irrelevant to connexin expression.

A 61-yr-old male patient presented with severe chest pain with cardiogenic shock due to an extensive anterolateral myocardial infarction. Two-dimensional echocardiogram showed severe left ventricular systolic dysfunction (ejection fraction=17%). Emergent coronary angiogram obtained immediately after placing temporary pacing electrode revealed total thrombotic occlusion in the left main stem. We performed direct coronary intervention using kissing balloon technique with the aid of Abciximab (ReoPro(R)) infusion. Residual stenosis with thrombus remained even after high pressure balloon dilatations, therefore we placed two stents, one in the ostia of left anterior descending (LAD) and the other in left circumflex artery (LCX). Coronary angiogram after kissing stents showed improved LAD and LCX flows without residual stenosis. Chest pain resolved and blood pressure normalized after coronary intervention. The whole procedure time was 15 min. Follow-up coronary angiogram taken one week later showed patent previous stented arteries, and echocardiography demonstrated 40% of left ventricular ejection fraction. The clinical course for one-year follow-up was uneventful.
