Esmolol is a cardioselective beta-blocker with a very rapid onset of action and a short half-life. Labetalol is a combined alpha- and beta-adrenoceptor blocking agent. It is a nonselective antagonist at beta-adrenoceptors and a competitive antagonist of postsynaptic alpha 1-adrenoceptors. A 51 year old female patient was transferred to the operating room for performing spinal fusion under general anesthesia. She had no operation and medication history. The initial heart rate was 150 beats/min. Despite administering several bolus injections of esmolol, the heart rate was not decreased to under 130 beats/min. But the heart rate was decreased to 100 beats/min after the administration of labetalol 5 mg and this rate was maintained without an additional injection. The vital signs were stable until the operation was finished and the patient recovered uneventfully in the recovery room. The postoperative laboratory findings revealed that she had hyperthyroidism. We report here on an anesthetic experience of effective labetalol treatment for esmolol-resistant tachycardia in a patient who was under general anesthesia.

BACKGROUND: We studied the hemodynamic changes induced by pneumoperitoneum and a reversed Trendelenburg in elderly patients with increased cardiac risk (ASA class III; n = 30; age 70.8 +/- 4.9 years, mean +/- SD) and compared the results with elderly patients at normal risk (ASA class II; n = 30; age 69.2 +/- 4.1 years) during laparoscopic cholecystectomy. METHODS: The transesophageal Doppler monitor was performed after induction of general anesthesia (pre-incision), after onset of pneumoperitoneum (insufflation), after head-up (20degrees) and a left lateral tilt (15degrees) (reversed Trendelenburg) and after deflation and horizontal position (desufflation). Mean arterial pressure (MAP), heart rate, cardiac index (CI) and systemic vascular resistance (SVR) were measured, respectively. RESULTS: Induction of pneumoperitoneum and head-up tilt in patients with cardiac risk resulted significantly in a decrease in CI and an increase in SVR compared with patients with normal risk (P < 0.05), and that remained until deflation, but no interval changes in MAP and heart rate. The CI, MAP and heart rate decreased and SVR increased significantly in patients with cardiac risk compared with patients with normal risk before incision (P < 0.05). No complications occurred. The results indicate that pneumoperitoneum and a reversed Trendelenburg are associated with significant but relatively benign hemodynamic changes. CONCLUSIONS: Anesthesia for laparoscopic cholecystectomy in elderly patients with increased cardiac risk should be performed with an adequate hemodynamic monitoring.

Background: This study aimed to determine whether serum uric acid (SUA) levels are associated with various indices of liver damage in the adult Korean population. Methods: We used the Seventh (VII) Korean National Health and Nutritional Examination Surveys. Our study population comprised 6,007 men and 8,488 women. Levels of SUA were divided into four groups (≤ 5.3, 5.3–6.0, 6.0–7.0, and > 7.0 mg/dL for men and ≤ 4.0, 4.0–4.8, 4.8–6.0, and > 6.0 mg/dL for women). Elevated liver enzyme levels were defined as > 35 (men) and > 31 (women) IU/L for aspartate aminotransferase (AST), > 45 (men) and > 34 (women) IU/L for alanine aminotransferase (ALT). Hepatic steatosis index and fibrosis (FIB)-4 index was used to determine nonalcoholic fatty liver disease (NAFLD) and liver FIB, respectively. Adjusted odds ratios (aORs) were calculated by logistic regression analysis for liver enzymes, NAFLD, and liver FIB, according to the SUA level. Results: Among women, the 4.8–6.0 and > 6.0 mg/dL SUA groups showed higher ORs of elevated AST (aOR, 1.78 and 2.03; 95% confidence interval [CI], 1.37–2.32 and 1.40–2.96, respectively; P < 0.001) and the 4.0–4.8, 4.8–6.0, and > 6.0 mg/dL SUA groups showed a higher ORs of ALT elevation (aOR, 1.35, 2.26, and 2.37; 95% CI, 1.02–1.79, 1.72–2.97, and 1.60–3.50, respectively; P < 0.001) compared to the lowest level SUA group. Among women with normal ALT, > 6.0 mg/dL SUA group showed higher OR of NAFLD status (aOR, 1.52; 95% CI, 1.06–2.19). Among men and women with NAFLD, hyperuricemia showed higher ORs of liver FIB (aOR, 2.25 and 1.89; 95% CI, 1.21–4.19 and 1.09–3.27, respectively) than the lowest level SUA group. Conclusion High SUA levels may be associated with elevated liver enzymes and NAFLD, mainly in women. Even in women with normal ALT levels, SUA levels may predict the NAFLD status. Hyperuricemia may predict advanced liver FIB in both men and women with NAFLD. Further studies investigating the causal effects of SUA on liver damage are required.

OBJECTIVE: The aim of the present study was to investigate the clinical usefulness of serum CA 125 and CA 19-9 levels for diagnosing and determining the severity of endometriosis. METHODS: A total of 112 women who underwent gynecologic surgery between January 1998 and August 2004 were selected in this study. 81 patients had histologically confirmed endometriosis and the remaining 31 had benign ovarian tumor but no obvious evidence of endometriosis. Blood samples were collected in all patients before the operation and the mean values and standard deviations of both serum CA 125 and CA 19-9 levels were measured in various stages of disease. Both tumor markers were also measured in the control group. The results were compared to determine the usefulness of CA 125 and CA 19-9 in diagnosing and predicting the severity of endometriosis. As a results, new cutoff values of serum CA 125 and CA 19-9 in endometriosis were obtained. RESULTS: The mean levels of serum CA 125 and CA 19-9 in patients at stage III and IV of endometriosis were significantly higher than in patients without endometriosis, and increased in accordance with the advancement of the clinical stage. Statistically appropriate cutoff values of CA 125 and CA 19-9 were calculated to be 20 IU/mL and 10 IU/mL, respectively. The sensitivity and specificity of CA 125 at this cutoff value for endometriosis were 72% and 71%, respectively. The sensitivity and specificity were 59% and 55% respectively in the case of CA 19-9. CONCLUSION: CA 125 is a useful marker for diagnosing and determining the severity of endometriosis. CA 19-9 shows limitation in diagnosing endometriosis, but is indeed a potential marker in predicting the severity of disease.

OBJECTIVE: To compare the effects of spinal stabilization exercise against with lumbar extensor strengthening exercise. METHOD: Sixty patients with chronic low back pain were enrolled into the study and randomly classified into three groups. Groups were treated with spinal stabilization exercise (Group 1), lumbar extensor strengthening exercise using a MedX machine (Group 2), or with a combination program (Group 3) for 8 weeks. Patients were not given any other treatment modalities. Isometric peak torque of the lumbar extensors, pain rating score (PRS), Medical Outcomes Study Short Form-36 (SF-36) score, and the Oswestry low back pain disability questionnaire (OLBPD-Q) were assessed at 0, 4, and 8 weeks of exercise. RESULTS: 1) After 8 weeks, all groups showed incremental improvements in maximal isometric torque of the lumbar extensors and exhibited improvement in SF-36, PRS, and OLBD-Q scores (p<0.05). 2) There were no significant differences in the degree of improvement among the three groups after 8 weeks of exercise. 3) The percentage of patients with scores of good or excellent in Group 3 was higher than in Groups 1 and 2 according to all evaluation tools. CONCLUSION: In the treatment of chronic low back pain, all exercise groups showed decreased pain, improved quality of life, and increased lumbar extensor strength regardless of the exercise type employed. We suggest that exercise programs in general are effective for the treatment of chronic low back pain and a combination exercise program seems to be most beneficial.

Noncirrhotic hyperammonemia as a cause of acute confusion remains diagnostic challenge. Deficiency of ornithine transcarbamylase (OTC) is the urea cycle disorder, inborn errors caused by a defect of the enzymes in the urea cycle, leading to an accumulation of ammonia mainly in newborn. There were very few cases, in which OTC deficiency result in hyperammonemia in adulthood. Herein, we report a young adult woman of hyperammonemic encephalopathy with OTC deficiency, diagnosed by high blood ammonia, glutamine and low plasma levels of citrulline. Next generation sequencing showed the c.386+5G>A mutation of the OTC gene.

Oxidative stress such as reactive oxygen species (ROS) within the inflamed joint have been indicated as being involved as inflammatory mediators in the induction of arthritis. Correlations between extracellular-superoxide dismutase (EC-SOD) and inflammatory arthritis have been shown in several animal models of RA. However, there is a question whether the over-expression of EC-SOD on arthritic joint also could suppress the progression of disease or not. In the present study, the effect on the synovial tissue of experimental arthritis was investigated using EC-SOD over-expressing transgenic mice. The over-expression of EC-SOD in joint tissue was confirmed by RT-PCR and immunohistochemistry. The degree of the inflammation in EC-SOD transgenic mice was suppressed in the collagen-induced arthritis model. In a cytokine assay, the production of pro-inflammatory cytokines such as, IL-1beta, TNFalpha, and matrix metalloproteinases (MMPs) was decreased in fibroblast-like synoviocyte (FLS) but not in peripheral blood. Histological examination also showed repressed cartilage destruction and bone in EC-SOD transgenic mice. In conclusion, these data suggest that the over-expression of EC-SOD in FLS contributes to the activation of FLS and protection from joint destruction by depressing the production of the pro-inflammatory cytokines and MMPs. These results provide EC-SOD transgenic mice with a useful animal model for inflammatory arthritis research.

PURPOSE: To evaluate the diagnostic accuracy of computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography/computed tomography (PET/CT) in predicting pelvic lymph node (LN) metastases in patients with cervical cancer. MATERIALS AND METHODS: From January 2009 to March 2015, 114 patients with FIGO stage IA1-IIB uterine cervical cancer who underwent hysterectomy with pelvic lymphadenectomy and took CT, MRI, and PET/CT before surgery were enrolled in this study. The criteria for LN metastases were a LN diameter ≥1.0 cm and/or the presence of central necrosis on CT, a LN diameter ≥1.0 cm on MRI, and a focally increased FDG uptake on PET/CT. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and accuracy for pelvic LN metastases were estimated. RESULTS: The sensitivity, specificity, PPV, NPV, and accuracy for detection of pelvic LN metastases were 51.4%, 85.9%, 41.3%, 90.1%, and 80.3% for CT; 24.3%, 96.3%, 56.3%, 86.8%, and 84.6% for MRI; and 48.6%, 89.5%, 47.4%, 90.0%, and 82.9% for PET/CT, respectively. The sensitivity of PET/CT and CT was higher than that of MRI (p=0.004 and p= 0.013, respectively). The specificity of MRI was higher than those of PET/CT and CT (p=0.002 and p=0.001, respectively). The difference of specificity between PET/CT and CT was not statistically significant (p=0.167). CONCLUSION: These results indicate that preoperative CT, MRI, and PET/CT showed low to moderate sensitivity and PPV, and moderate to high specificity, NPV, and accuracy. More efforts are necessary to improve sensitivity of imaging modalities in order to predict pelvic LN metastases.
