Head tilt test is useful in diagnosing cyclovertical muscle palsy, especially superior oblique palsy, In this study, we observed efficacy and pattern of head tilt test in 12 patients of unilateral superior oblique palsy(7 congenital, 4 traumatic and 1 vascular) who had abnormal head tilt to nonparetic side. The results of head tilt test were compared to preoperative status in 8 patient, 3 month after surgery. All patients in this study showed positive response of head tilt test. Among them, 9 patients showed definite elevation of paretic eye. However, 2 patients mainly showed definite depression of nonparetic eyes that were amblyopic. The last patient did not show definite vertical deviation in either eye but complained of increasing diplopia. After surgery, abnormal head tilt and positive head tilt response disappeared in 7 patients. In conclusion, preoperative head tilt test is one of the valuable methods in diagnosisng unilateral superior oblique palsy especially in young patients and in those who developed spread of comitance. In addition, the positive head tilt test does no always mean the elevation of paretic eye.

Diffuse alveolar hemorrhage is life-threatening situation which is rarely caused by paraganglioma or pheochromocytoma. Here, we describe anesthetic management of 64-year-old man underwent laparoscopic pararenal mass excision and later on this mass diagnosed as paraganglioma. We induced anesthesia with propofol 120 mg, sufentanil 12.5 μg, and rocuronium 50 mg. Anesthesia was maintained with sevoflurane administration. Patient position was changed to right lateral decubitus position for laparoscopic approach. Vital signs were stable until direct stimulation of mass. When surgeon started to manipulate pararenal mass, blood pressure suddenly increased to 274/169 mmHg and heart rate also increased to 140 beat/minute. SpO2 dropped to 69% and bilateral lung sounds decreased. We used intravenous esmolol to control blood pressure and heart rate. In doubt for bronchial spasm, we used intravenous hydrocortisol and chlorpheniramine maleate. Discharge of bloody fluid was obtained from endotracheal tube. Immediate postoperative chest x-ray showed diffuse air space consolidation in right lung field. We assessed as unilateral alveolar hemorrhage and patient was transferred to intensive care unit (ICU) without endotracheal extubation. The patient was followed up with ventilator care and antibiotic treatment in ICU, and daily chest x-ray was taken. He was extubated after showing favorable prognosis on postoperative day (POD) 4, and discharged on POD 7. Anesthesiologist should be aware that incidental manipulation of undiagnosed catecholamine producing tumor can lead to fatal consequences, and should know the management of hypertensive crisis and bronchial spasm.

Background: Sympathetic blocks (SBs) have been used widely to relieve the symptoms of sympathetically maintained pain (SMP). The thoracic sympathetic ganglion is not separated from somatic nerves by muscles and connective tissue. The upper thoracic ganglion runs along the posterior surface of the vertebral column in close proximity to the adjacent epidural region. This anatomical difference leads to frequent epidural and intercostal spread in cases of thoracic SBs. The purpose of this study was to investigate the incidence of inadvertent intercostal and epidural injections during thoracic SBs. Methods: Twenty-two patients who were suffering from complex regional pain syndrome or lymphedema after breast cancer surgery were managed with two or three times of thoracic SBs. Therefore, injections of 63 thoracic SBs from 22 patients were enrolled in this study. An investigator who did not attend the procedure evaluated the occurrence of intercostal or epidural spread using anteroposterior fluoroscopic images. Results: The overall incidence of inadvertent intercostal or epidural spread of contrast was 47.5%. Among the inadvertent injections, intercostal spread (34.9%) was more frequent than epidural spread (12.6%). Only 52.5% of the thoracic SBs demonstrated successful contrast spread without any inadvertent spread. The mean difference in skin temperature between the blocked and unblocked sides was 2.5 ± 1.8ºC. Fifty-nine (93.6%) injections demonstrated more than 1.5ºC difference. Conclusions Thoracic SBs showed a high incidence (47.5%) of inadvertent epidural or intercostal injection. Thus, special attention is required for the diagnosis of SMP or the injection of any neurolytic agent around sympathetic ganglion.

OBJECTS: It has been reported that the incidence of tardive dyskinesia(TD), the remarkable abnormal involuntary movement, was higher in the schizophrenics with high blood sugar levels and that TD had been improved by small amount of insulin-injection for 90 days. And also it was generally known that the blood lipids were higher in the schizophrenics with tardive dyskinesia. Thus, we tried to replicate the correlations of abnormal involuntary movements with blood sugar levels and blood lipids in chronic schizophrenics treated with antipsychotics. METHODS: Thirty-eight male schizophrenic inpatients who were stable in clinical state with medications, were included. The patients who had been already diagnosed as diabetes mellitus(DM), organic brain disorder, substance-related disorder, physical illness were excluded and also we excluded female patients to remove the hormonal effect on TD. Eleven patients who ranked higher(above five) in the Abnormal Involuntary Movement Scale(AIMS) were assigned into 2 groups, a dibenese group and a placebo group. Diabinese or placebos were administrated for 3 weeks with antipsychotics and AIMS was rechecked. RESULTS: There were no correlations between the total AIMS scores and blood sugar and lipids levels in all subjects. The means of total and subscale scores(objective, face, and extremity) of AIMS did not reveal statistical significances between diabinese and placebo groups. However(total, jaw, face, upper arm, and objective feeling), were statistically higher in the diabinese group than those in the placebo group. And correlations of total cholesterol(TC) with fast blood sugar(FBS), weight with body mass index(BMI) and waist, total glycerol (TG) with BMI were statistically significant. CONCLUSION: In this study, there were statistical significances in the changes in ratings of AIMS scores between the diabinese group and the placebo group. Application of oral hypoglycemic agent might be a way of improving abnormal involuntary movements in schizophrenics with abnormal involuntary movements or TD. Althogugh it was not certain that there were correlations of abnormal involuntary movement with blood sugar and lipids, correlations of TC/TG with AIMS, of FBS with AIMS cautiously suggest that the regular check of HbA1C, waist, and weight are recommended for schizophrenics.

Background: Robot-assisted laparoscopic radical prostatectomy is an advanced and popular surgical technique. However, increased intracranial pressure which is caused by CO2 pneumoperitoneum and Trendelenburg position is the main cerebrovascular effect. Measurement of optic nerve sheath diameter using ocular ultrasound is a noninvasive and reliable method for the assessment of intracranial pressure. The primary endpoint of this study was to identify whether low blood pressure regulation has any benefit in attenuating an increase of optic nerve sheath diameter during robot-assisted laparoscopic radical prostatectomy. Methods: Optic nerve sheath diameter and cerebral oxygen saturation were measured at baseline (supine position), one and two hours after pneumoperitoneum and Trendelenburg position respectively, and after return to supine position in normal (n = 27) and low blood pressure groups (n = 24). Results: Mean optic nerve sheath diameter values measured at one and two hours after pneumoperitoneum and Trendelenburg position were significantly increased compared to the baseline value (P < 0.001 in normal blood pressure group; P = 0.003 in low blood pressure group). However, the mean optic nerve sheath diameter and cerebral oxygen saturation measured at any of the time points as well as degrees of change between the two groups did not show any significant changes. The peak values of optic nerve sheath diameter in normal and low blood pressure groups demonstrated 14.9% and 9.2% increases, respectively. Conclusions Low blood pressure group demonstrated an effect in maintaining an increase of optic nerve sheath diameter less than 10% during CO2 pneumoperitoneum and Trendelenburg position.

BACKGROUND: Dutasteride is an inhibitor of both types I and II 5 alpha-reductase and was approved in Korea in April 2004. This post-marketing surveillance was to assess the safety of dutasteride in Korean patients with benign prostate hyperplasia in real life and to elucidate the risk factors related adverse events. METHODS: From December 2004 to January 2010, 3,977 patients were enrolled by 184 urologists. According to post-marketing surveillance regulation, patients were enrolled consecutively. Patients administered dutasteride at least once were included in safety assessment. The incidences of any adverse events and serious adverse events were evaluated. Multiple logistic regression method was used to identify risk factors related to adverse events. RESULTS: The safety assessment included 3,870 patients with the mean age of 67.3 years. The incidence of adverse events was 3.8 %. The most frequent adverse event was impotence (75 cases, 1.9 %), libido decrease (49 cases, 1.3 %), ejaculation disorder (30 cases, 0.8 %), and gynecomastia (5 cases, 0.1 %). The incidence of unexpected adverse events was 0.5 % and cerebral infarction, lung cancer, pulmonary embolism, and diarrhea were reported as serious adverse events. CONCLUSION: In this survey, impotence was the most frequently reported adverse events. Dutasteride was well tolerated in Korean patients with benign prostate hyperplasia. These results updated the safety information and would provide important additional information for prescribers.

PURPOSE: hear stress (SS) and cyclic strain (CS) influence the expression of membrane type 1-matrix metalloproteinase (MT1-MMP) in microvascular endothelial cells (MVECs). It is known that changes in the level of Sp1 phosphorylation are important for MT1-MMP expression following SS and CS. However, the exact mechanism underlying this process is poorly understood. The aim of this study was to determine the effect of PKCzeta on serine phosphorylation and activation of Sp1 in response to SS and CS. METHOD: MVECs were exposed to SS or CS for up to 8 hours with or without PKCzeta inhibitors. The activity and phosphorylation of Sp1 were assessed by Western blot analysis and immunoprecipitation. MT1-MMP protein expression was assessed by Western blot analysis. RESULT: PKCzeta was phosphorylated and activated under SS, whereas no significant changes were noted under CS. SS increased Sp1 phosphorylation in a time-dependent manner, but no changes in the Sp1 phosphorylation were observed when the MVECs were pretreated with the PKCzeta inhibitors. By contrast, MVECs exposed to CS in the presence or absence of PKCzeta inhibitors showed no change in the phosphorylation of Sp1. SS decreased MT1-MMP protein expression in a time-dependent manner, but in the presence of PKCzeta inhibitors, MT1-MMP expression was not changed compared with the static levels after SS. CS increases MT1-MMP expression in a time-dependent manner. Similar expression was observed when the cells were pretreated with PKCzeta inhibitors under CS. CONCLUSION: These data demonstrate that the increased affinity of Sp1 for the MT1-MMP's promoter site occurs because of PKCzeta induced phosphorylation of Sp1 in response to SS.

When pericardial tamponade occurs to the left ventricular assist device (LVAD) implanted patients, typical hemodynamic signs of tamponade such as tachycardia and pulsus paradoxus may be masked by LVAD action. For those with normal heart, anesthetic management during pericardial tamponade operation before drainage is to restrict fluid administration and maintain perfusion pressure with vasopressor are recommended. But the things to concern are different in cases of patient with LVAD. Here, we describe a case of performing anesthesia with LVAD implanted patient for pericardial tamponade operation. A 58-year-old male with HeartWare™ (Medtronic, Framingham, MA, USA) LVAD implant was referred for cardiac tamponade surgery. After the induction of general anesthesia, his mean arterial pressure (MAP) decreased to 38 mmHg with device flow 1.8 L/min and device power 2.4 Watts at pump speed 2,400 RPM. Norepinephrine and Epinephrine infusion were initiated. MAP recovered to 70mmHg with device flow 3.7 L/min and power 3.0 Watts after the drainage of 1,200 cc of pericardial fluid. Cardiac tamponade with LVAD implanted patient present with decreased peak flow, mean flow and decreased pulsatility. LVAD flow depends on pump rotation, preload and afterload. In order to maintain flow in these patients, prevention of preload reduction is important. Since LVAD implantation becoming more popular as Bridge to transplantation and destination therapy, it is important for anesthesiologist to understand the LVAD parameters and factors that affect.
