BACKGROUND AND OBJECTIVES: Recurrent vestibulopathy is defined a disease characterized by more than a single episode of vertigo of duration characteristic of endolymphatic hydrops but without auditory or clinical neurological symptoms or signs. To investigate the clinical characteristics and the efficacy of combination therapy, we analyzed the clinical records of the patients diagnosed as recurrent vestibulopathy. MATERIALS AND METHOD: Clinical records of sixty four patients diagnosed as recurrent vestibulopathy were retrospectively reviewed. The data on age, sex distribution, natural history, family history of recurrent vestibulopathy, concurrent headache, caloric response was analyzed. The efficacy of combination therapy for vertigo control in the patients with a minimum 24-month follow-up was also evaluated. RESULTS: Mean onset age of recurrent vestibulopathy was 43 years and there was a female preponderance. Concurrent headache and elevated SP/AP ratio in electrocochleogram was frequently observed in these patients. After the combination medical therapy, patients with severe recurrent vestibulopathy showed significant decrease in the number of vertigo spells with 37.5% of complete control of vertigo. CONCLUSION: As a distinctive clinical disorder with unknown cause, recurrent vestibulopathy should be always considered to the patients complaining recurrent episodic vertigo. Combination therapy individualized to the symptoms and signs of the patients with recurrent vestibulopathy might be effective in reducing the frequency of vertigo attacks. Further case-control studies with large population should be necessary.

We report a case of intrasellar arachonoid cyst with extension to the sphenoid sinus, which is a very uncommon lesion. Preoperatively, we studied the PNS CT & Brain MRI and these images showed a large cyst in the widened sellar turcica with extension to the sphenoid anterior wall. We planned endoscopic surgery via transnasal-transphenidal approach. The endoscopic surgery was performed with no complication. We reviewed the literature and discussed the treatment of the intrasellar arachnoid cyst.

Adult-onset Still's disease is an uncommon systemic inflammatory disease of unknown etiology and pathogenesis. It is characterized by an evanescent rash, spiking fever (>39degrees), arthralgia, sore throat, abnormal liver function tests and leukocytosis (>10,000/mm3). We report a case involving a 41-year-old male with initial symptoms suggestive of anaphylactic and septic shock. Steroid therapy led to recovery. Adult-onset Still's disease was ultimately confirmed.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the incidence and prognostic significance of cervical lymph node metastasis in squamous cell carcinoma (SCC) of the hypopharynx. SUBJECTS AND METHOD: A retrospective review of the 64 patients who were previously untreated for SCC of the hypopharynx and underwent surgery was performed from October 1993 to June 2008. Fifty-six patients had simultaneous bilateral neck dissection, whereas eight had unilateral neck dissection. RESULTS: The median age was 61.0 years (range, 34-75 years) for the study group consisting of 62 males and two females. Evaluating according to the N stages, there were 15 (23.4%), 10 (15.6%), 37 (57.8%), and 2 (3.1%) cases with N0, N1, N2 and N3, respectively. Forty-nine patients (76.6%) had pathologically proven cervical metastasis. Contralateral occult lymph node metastasis occurred in 20.5%. Ipsilateral and contralateral occult metastasis rates for clinically node negative patients were 41.2% and 11.8%, respectively. The most frequent sites for positive neck nodes occuring at each level were as follows: II (48.5%), level III (40.6%), level IV (26.6%), paratracheal node (21.4%), level V (9.4%), levels I (7.8%), and retropharyngeal node (6.3%). The 5-year overall survival and disease-specific survival rates were 50% and 53%, respectively. Cervical nodal metastasis (p=0.044) was statistically significant prognostic factors for disease-specific survival. CONCLUSION: Metastasis to the cervical lymph node group is very frequent and has an impact on survival in patients with hypopharyngeal SCC. Therefore, we advocate bilateral neck dissection in patients with hypopharyngeal SCC with clinically positive metastasis. Ipsilateral elective neck dissection may be needed for clinically node negative patients.

Although several reports have showed the application of 3-dimensional (3D) echocardiography, it is hard to find a report regarding the intraoperative use of real time 3D transesophageal echocardiography (TEE) in mitral valve repair surgery. In the present case, real time 3D TEE the one from the one TEE probe position as well as their rotated and cropped images showed detailed spatial images enough for immediate assessment of the mitral valve deformity and the characteristics of mitral regurgitation flow. Under cardiopulmonary bypass (CPB) employing moderate hypothermia, the prolapsed mital leaflet was excised, the ruptured cord was repaired and an annuloplasty ring was inserted to reinforce the mitral valve and to close up the defect. The 2D and 3D TEE images after CPB showed effective repair providing complete closure of the mitral leaflets and absence of residual regurgitation flow. Considering that the conventional 2D TEE requires examiner's ability to gather the various 2D TEE images and experience essential for intergrating the 2D images for full understanding of spatial structure of valvular deformity and dysfunction, 3D TEE's ability for making a comprehensive spatial image from a limited number of 2D images seems to have an additional clinical efficacy in intraoperative TEE monitoring for cardiac value surgery.

The determination of arterial pressure wave-derived cardiac output (APCO) and central venous O2 saturation (ScvO2) has been introduced as a less invasive procedure for monitoring cardiac function and oxygen delivery. We have used an APCO sensor (FloTracTM) and a monitor for ScvO2 (Vigileo(TM)) in two cases of cardiac valve surgery, where placement of pulmonary artery catheter (PAC) was not applicable due to unfavorable cardiac structure (case 1) and was contraindicated due to an unstable cardiac conduction disorder and arrhythmia (case 2). In case 1, monitoring of APCO was started from the beginning of anesthesia induction and a ScvO2 monitoring central venous catheter was inserted just after anesthesia induction. APCO, ScvO2 and other hemodyanamic information such as arterial BP, CVP, and data obtained from transesophageal echocardiography (TEE) during the pre- cardiopulmonary bypass (CPB) period were measured. APCO and ScvO2 during the post-CPB period showed a reliable correspondence with continuous cardiac output (CCO) and mixed venous O2 saturation (SvO2) as measured by PAC at the end of CPB. In case 2, APCO and ScvO2 were monitored instead of CCO and SvO2. The values of APCO showed a good correlation to intraoperative COs indirectly calculated by the velocity-time integral of the aortic outflow determined in the TEE examination. We experienced that monitoring APCO and ScvO2 is useful for anesthesia management in cardiac valve surgery and can be an alternative to CCO and SvO2 if the placement of PAC and the thermodilution method are not applicable.

During off-pump coronary artery bypass graft surgery (OPCAB), vigorous displacement and compression of the heart producing significant hemodynamic change are essential for optimal exposure of graft anastomoses. Intraoperative transesophageal echocardiography (TEE) is useful in determining hemodynamic compromise and prompting medical and mechanical support. However, in addition to the loss of contact between the heart and diaphragm during the displacement, swabs or snears underneath the heart interrupt the TEE signal transmission, resulting in a compromised transgastric (TG) TEE view. Therefore, TEE monitoring during OPCAB is usually limited to the mid-esophageal view. The authors placed a saline bag (a surgical glove filled with saline) underneath the heart to facilitate this anterior displacement of the heart, as well as avoid the signal interruption of the TG echocardiographic window. As a result, the optimal heart position with the minimal changes in LV regional wall motion, LV function and mitral regurgitation were found using the TG and other TEE views. The series of velocity-time integral of aortic valvular flow (VTI-Ao) in TG long axis view, in addition to SvO2, were then monitored as a surrogate marker of the cardiac output during a graft construction of the left circumflex artery. It was concluded that the use of a saline bag may be useful in avoiding compromise of the TG TEE view and determine the hemodynamic change using VTI-Ao during cardiac displacement for OPCAB.

Background/Aims: Gastrointestinal bleeding (GIB) risk for non-vitamin K antagonist oral anticoagulants (NOACs) compared with warfarin is largely unknown. We aimed to determine the risk of overall and post-polypectomy GIB for NOACs and warfarin. Methods: Using the Korean National Health Insurance database, we created a cohort of patients who were newly prescribed NOACs or warfarin between July 2015 and December 2017 using propensity score matching (PSM). Kaplan-Meier analysis with log-rank test was performed to compare the risk of overall and post-polypectomy GIB between NOACs (apixaban, dabigatran, and rivaroxaban) and warfarin. Post-polypectomy GIB was defined as bleeding within 1 month after gastrointestinal endoscopic polypectomy. Results: Out of 234,206 patients taking anticoagulants (187,687 NOACs and 46,519 warfarin), we selected 39,764 pairs of NOACs and warfarin users after PSM. NOACs patients showed significantly lower risk of overall GIB than warfarin patients (log-rank P<0.001, hazard ratio, 0.86; 95% confidence interval, 0.78–0.94; P=0.001). Among NOACs, apixaban showed the lowest risk of GIB. In the subgroup of 7,525 patients who underwent gastrointestinal polypectomy (lower gastrointestinal polypectomy 93.1%), 1,546 pairs were chosen for each group after PSM. The NOACs group showed a high risk of post-polypectomy GIB compared with the warfarin group (log-rank P=0.001, hazard ratio, 1.97; 95% confidence interval, 1.16–3.33; P=0.012). Conclusions This nationwide, population-based study demonstrates that risk of overall GIB is lower for NOACs than for warfarin, while risk of post-polypectomy GIB is higher for NOACs than for warfarin.

BACKGROUND: Calculation of the base excess (BE) and the anion gap (AG) is commonly used to identify the presence and to analyze the cause of metabolic acidosis in critically ill patients. However, the calculation of BE assumes normal water content, electrolytes, and albumin, changes in these values will change the calculated BE. Calculation of the AG does not control for changes in albumin and cannot distinguish plasma concentration changes of negatively charged protein (albumin) from that of other anions. Based on Stewart's physicochemical principles, Gilfix et al developed equations to calculate the BE caused by unmeasured anions (BEua) taking into account changes in free water, chloride, albumin, and PCO2 that theoretically should reflect metabolic changes better than the less complete biochemical measurements. This study was designed to evaluate the influence of BEua and other variables on the length of postoperative hospital stay. METHODS: The data from 100 consecutive patients were collected prospectively in patients who underwent intra-abdominal operations under general anesthesia and admitted to the adult intensive care unit. All samples were routine samples taken from arterial lines postoperatively and analyzed for arterial blood gas, plasma electrolytes, inorganic phosphates and albumin concentrations. BEua was calculated from the equations developed by Gilfix et al. We also calculated AGNa, K (Na++K+-Cl--HCO3-) and AGNa (Na+-Cl--HCO3-). Correlations between the length of postoperative hospital stay and these variables were studied using linear regression analysis. RESULTS: BEua and BE were significantly correlated with the length of ICU stay (r=0.295, p<0.01 and r=0.249, p<0.05). Neither AGNa, K nor AGNa was correlated with the length of ICU stay. Significant correlation was observed between the length of postoperative hospital stay and BEua (r=0.316, p<0.01), BE (r=0.288, p<0.01), AGNa, K (r=0.284, p<0.01), and AGNa (r=0.263, p<0.05). CONCLUSIONS: In this study BEua was significantly correlated with the length of ICU stay and postoperative hospital stay compared with other variables. This finding suggests that BEua may be used as a more reliable predictor of outcome in ICU patients.
