A 55 yr -old female patient visited to the OPD of OS department complaining of the lumbago, the radiating pain to right thigh and the swelling of right knee and calf regions. On routine chest and abdominal X -ray and ECG, the dextrocardia was revealed. For further detail examination, Doppler US, lung perfusion scan, MRI images were obtained. As a result, the situs inversus with dextrocardia was confirmed. Other congenital anomalies or diseases were not combined. The patient was cared with conservative treatment of lowback pain via OPD. And she was recovered successfully.

PURPOSE: We investigate biases in the assessments of left ventricular function (LVF), by compressed sensing (CS)-cine magnetic resonance imaging (MRI). MATERIALS AND METHODS: Cardiovascular cine images with short axis view, were obtained for 8 volunteers without CS. LVFs were assessed with subsampled data, with compression factors (CF) of 2, 3, 4, and 8. A semi-automatic segmentation program was used, for the assessment. The assessments by 3 CS methods (ITSC, FOCUSS, and view sharing (VS)), were compared to those without CS. Bland-Altman analysis and paired t-test were used, for comparison. In addition, real-time CS-cine imaging was also performed, with CF of 2, 3, 4, and 8 for the same volunteers. Assessments of LVF were similarly made, for CS data. A fixed compensation technique is suggested, to reduce the bias. RESULTS: The assessment of LVF by CS-cine, includes bias and random noise. Bias appeared much larger than random noise. Median of end-diastolic volume (EDV) with CS-cine (ITSC or FOCUSS) appeared −1.4% to −7.1% smaller, compared to that of standard cine, depending on CF from (2 to 8). End-systolic volume (ESV) appeared +1.6% to +14.3% larger, stroke volume (SV), −2.4% to −16.4% smaller, and ejection fraction (EF), −1.1% to −9.2% smaller, with P < 0.05. Bias was reduced from −5.6% to −1.8% for EF, by compensation applied to real-time CS-cine (CF = 8). CONCLUSION: Loss of temporal resolution by adopting missing data from nearby cardiac frames, causes an underestimation for EDV, and an overestimation for ESV, resulting in underestimations for SV and EF. The bias is not random. Thus it should be removed or reduced for better diagnosis. A fixed compensation is suggested, to reduce bias in the assessment of LVF.

BACKGROUND AND OBJECTIVES: The conventional transseptal transsphenoidal approach can inhibit visualization of the surgical field and may change the shape of external nose. We used the transseptal transsphenoidal technique to remove septal cartilage except the L strut via a modified Killian's incision and preserved the ‘key-stone area.’ The aim of this study was to verify the usefulness of this technique. SUBJECTS AND METHOD: Retrospective analysis was carried out on 42 pituitary tumor patients who received this technique by a single otolaryngologist from March 2005 to March 2012 at Kangbuk Samsung Hospital. RESULTS: The mean patient age at time of surgery was 52 years, and 41 cases were pituitary adenoma and 1 was Rathke's cleft cyst. Three patients had undergone prior surgery; of which 2 used a pterional approach and 1 a transsphenoidal approach. With regard to complication, there were 2 cases of CSF leakage and 5 cases of septal laceration. There were no cases of meningitis, deformity of external nose, septal perforation, anosmia, or sinusitis. In post operation follow up, 25 cases (59.5%) had no residual tumor, while 17 cases (40.5%) had residual tumor. CONCLUSION: This study reveals that transseptal transsphenoidal surgery with septal cartilage removal and a replacement technique for a pituitary tumor are effective, allow easy exposure, and result in a low complication rate.

The pathophysiological mechanism of cardiovascular disease in patients with chronic kidney disease (CKD) is complicated. Mediation analysis is an important statistical tool for gaining insight into the complex mechanisms of exposure-outcome effects. We investigated the potential mediating role of the left ventricular mass index (LVMI) on the association between fluid balance (overhydration/extracellular water, OH/ECW) and left ventricular diastolic function (E/e´ ratio) in patients with CKD not yet on dialysis. Methods: Bioimpedance spectroscopy, echocardiography, and laboratory evaluations were performed on 425 consecutive patients on the same day. The patients were classified into two groups according to the estimated glomerular filtration rate corresponding to CKD stages 3 and 5. Mediation analysis was performed using the PROCESS macro and bootstrapping methods. Results: OH/ECW and LVMI were positively correlated with the E/e´ ratio in both the CKD stages 3 and five groups. In CKD stage 5, there was a statistically significant association between OH/ECW and LVMI, whereas no correlation was observed in CKD stage 3. In the mediation analysis, LVMI positively mediated the relationship between OH/ECW and E/e´ ratio when controlling for confounders in patients with CKD stage 5 (B = 2.602; Boot 95% confidence interval, 1.313–4.076). Conclusion: In our analysis, the indirect effect of mediators was significant in patients with advanced CKD. Therefore, our study suggests that further research on several other risk factors may be needed to determine the underlying mechanisms of association between the associated factors in all CKD stages.

Because sublingual region is well-vascularized and sublingual artery is passed throughout this region, it should be careful not to perforate lingual cortex when placing dental implant on mandible. A 83-years-old male complained severe sublingual hematoma, hemorrhage and dyspnea came our outpatient department. He had received dental implant placement in the same day. He needed hemostasis and airway control. If soft tissue of sublingual region and the artery are injured, it may result in life-threatening excessive hemorrhage. In dental implant surgery, especially mandible, we should recognize the accurate shape of mandible and anatomy of sublingual region. It is important to stop anticoagulant agent before surgery. When a patient has airway obstruction, the operator should manage airway quickly.

IgA nephropathy is usually localized to the kidney, however, it can accompany systemic disease, including gastrointestinal disease, skin disease, connective tissue disease, and malignant tumor. In some patients with IgA nephropathy which manifested as an extraintestinal symptom of Crohn's disease, recovery of renal function was achieved following treatment of Crohn's disease. The pathophysiology of each disease remains unclear. According to some studies, however, immunological, genetic, and environmental factors may be involved in a complex manner. In patients receiving renal replacement therapy for treatment of renal dysfunction due to IgA nephropathy, occurrence of Crohn's disease as an extrarenal symptom has not been reported. We experienced a case of Crohn's disease which developed in a patient receiving hemodialysis for treatment of end-stage renal disease due to IgA nephropathy.

PURPOSE: The surgical treatment of burn patient is associated with substantial blood loss. Therefore, multiple hemostatic techniques have been proposed for this problem. Unfortunately, a clear conclusion as to the best hemostatic agent cannot be made. Then, we present our experience of using Fibrin sealant (TISSEEL(TM)) in extremity operation. METHODS: We reviewed the medical records of 10 patients treated in our burn center who conducted the extremity operation using Fibrin sealant from January 2010 to December 2010. RESULTS: The mean tourniquet time is within 60 minutes and no need of transfusion during the operation in all patients. The average take rate for skin graft is over the 98%. No one has nerve injury and other problems. CONCLUSION: Fibrin sealant is a human derived factors that are designed to reproduce the final step of the physiologic coagulation cascade of a stable fibrin clot. In addition, Fibrin sealant has the advantage of being biocompatible and biodegradable, without inducing inflammation, foreign body reaction, and tissue necrosis. Fibrin sealant is shown to be effective methods to achieve hemostasis for the extremity burn surgery.

BACKGRAOUND/AIMS: The biologic nature of polypoid lesions of gallbladder is difficult to define before surgical intervention and operative indication is still controversial. The aim of this study is to provide surgical guideline for polypoid lesions of gallbladder. METHODS: Clinical data were retrospectively correlated with the histopathologic characteristics of polypoid lesions of gallbladder in 48 patients who had cholecystectomy from January 1992 to August 2002 in the Department of Surgery, Kang-nam General Hospital Public Corporation. RESULTS: There were 40 benign polypoid lesions including 30 cholesterol polyps, 5 adenomas, 4 inflammatory polyps and 1 adenomyomatous hyperplasia and 8 malignant polypoid lesions. Data analysis showed that neoplastic polypoid lesions of gallbladder correlated significantly with size and malignant polypoid lesions of gallbladder correlated significantly with size and age. CONCLUSION: The risk factor for neoplasm was the size of the polypoid lesions of gallblaldder (> or =10 mm) and the risk factors for malignancy were the size of the polypoid lesions of gallblaldder (> or =10 mm) and age (> or =50). Surgical intervention should be considered when a polypoid lesion of the gallbladder is larger than 10 mm and patient is older than 50 years.

The incidence of aspergillosis infections in the maxillary sinus has increased recently, because of overuse of antibiotics, steroids, anticancer agents, immunosuppressant, antimetabollites, and uncontrolled diabetes mellitus. The clinical features of maxillary sinus aspergillosis include pain, swelling and foul odor nasal excretion. This needs to be differentiated from bacterial maxillary sinusitis, and surgical treatment with antifungal agents are suggested. Recently, we treated two patients with maxillary sinus aspergillosis surgically (Caldwell Luc operation) and with antifungal agents(itraconazole). The results were satisfactory so we report these cases with literature review.

Increased or decreased pulmonary blood flow (PBF) and an increased pulmonary vascular resistance (PVR), represent common and important change in pulmonary hemodynamics. In this study, we constructed 3 hemodynamic models in 5 dogs, that is, an increased and a decreased PBF model, and an increased PVR model. A CT perfusion scan was performed in each hemodynamic model. Perfusion parameters including blood flow (BF), blood volume (BV), mean transit time (MTT), and maximal slope (MS) were calculated automatically by specialized software and analyzed for changes according to hemodynamic status. In terms of the normal state, blood flow was affected by gravity and dependent area showed higher BF and BV and lower MS and MTT than the non-dependent area. The decreased PBF model showed a significant increase in BF and MS (p=0.046, 0.005) but no significant change in BV (p > 0.05), and a slight elongation of MTT (p > 0.05) versus the normal state. The increased PBF model showed a slightly increased BV and a slightly decreased MTT (p > 0.05). The increased PVR model showed significant reduction in BF, BV, and MS (p < 0.000, 0.007, 0.000) and a slight increase in MTT, but without statistical significance (p > 0.05). However, it was noticeable that the distribution of MTT with respect to gravity in the normal lung was completely reversed in the increased PVR model. In conclusion, based on our understanding of perfusion characteristic in normal state, abnormal regional hemodynamic changes in the lung can be detected and evaluated. Predicting changes in pulmonary vascular resistance should be possible by a thorough analysis of CT perfusion parameters.
