Intraperitoneal hyperthermic perfusion(IPHP) was performed under combined epidural & general anesthesia in 57 year old female patient with recurrent ovarian cancer. She had past history of diabetes mellitus. Metabolic acidosis & hypokalemia were already developed before IPHP and aggravated during IPHP. NaHCO3 300mEq & KCl 40mEq were administered intravenously for three hours. In this case, we deduced that the causes of metabolic acidosis may be anaerobic glycolysis due to peripheral circulatory impairment from hypothermia, degradation of tumor cells by hyperthermia, and poor general condition with prolonged operation. The causes of hypokalemia were suspected to be continuous infusion of regular insulin, massive NaHCO3 administration, and diabetic ketoacidosis. Therefore, we recommend when performing IPHP in DM patient, precise preoperative evaluation and careful monitoring of arterial blood gas & electrolyte.

The local laser solidification treatment among the therapys of age-related macular degeneration, which is immensely important in the field of ophthalmology, has been admited to be of effect. The accurate scope and the times of the cure not only play a important role of convalescence but also have a great influence on eyesight in the laser remedy. The retinal image photographed by a recent technology of ICG(Indocyanine Green) give us easy observation of avascular zone, and let us understand and predict objectively the degree of age-related macular degeneration. In this paper, we introduce the ICGI Analyzer and explain ICG image analysis methods that masure in quantities regions of hyperfluorescein area by choroidal neovascularization and detect transformations of it by image processing techniques. Also, we descript a method that ophthalmologist classify ICGA into several types on the basis of position of CNV(Choroidal NeoVascularization) using this system. We present results of applying ICG retinal image of patients to ICG Analyzer and typical frequency of age-related macular degeneration investigated by experts for testing the objectivity and accuracy of proposed methods.

BACKGROUND: Catheter ablation using radiofrequency energy has been established as the most important mode of treatment in patients with accessory pathway. However the ablation of midseptal accessory pathways had been recognized as being more difficult to ablate than other located pathway because of the low incidence and the difficult localization of ablation site. This paper describes the electrophysiologic characteristics of successfully ablated midseptal accessory pathway using radiofrequency energy. METHOD: Routine electrophysiologic studies were performed in 13 patients with midseptal accessorypathway. Guided by the recording of VA interval, the ablation catheter was positioned in all patients in an area bounded anteriorly by the tip electrode of the His bundle catheter and posteriorly by the coronary sinus ostium. Local electrograms during orthodromic atrioventricular reentrant tachycardia or right ventricular apical pacing were compared for 13 patients with midseptal accessory pathway and consequent 13 patients with posteroseptal accessory pathway. RESULT: 13 patients with midseptal accessory pathway; eight with constant Wolff-Parfinson-White syndrome, one with intermittent Wolff-Parkinson-White syndrome and four with concealed bypass track underwent attempts at ablation of their pathway using radiofrequency energy. 11 accessory pathways were successfully ablated without complication during the firstsession. A second attempt at ablation was made in two patients with success(one; recurred case, the other one; failed case at the first session). In the surface 12-Lead ECG, all eight patientswith constant Wolff-Pakinsin-White syndrome had not shownen Qrs complex at lead 3. Two patient with midseptal accessory pathway had transient left bundle branch block during orthodromic tachycardia. The VA interval during left bundle branch block was not change compared to that during narrow complex tachycardia in both. In all patients with midseptal accessory pathway, the VA interval in his bundle electrogram were almost similar to that in the coronary sinus ostial electrogram, which was not observed in the patients with posteroseptal accessory pathway. CONCLUSION: We suggest that VA interval during orthodromic tachycardia and right ventricular apcial pacing is the most reliable market for identifying midseptal accessory pathway, especially distinguishing from posteroseptal accessory pathway.

Glassy cell carcinoma is a histologic subtype of cervical cancer with distinct pathologic features and it has an aggressive biologic course. It was first described by Glucksmann and Cherry in 1956 as a poorly differentiated adenoquamous carcinoma and commented on its poor prognosis, unresponsiveness to traditional modes of therapy, and often associated with pregnancy. The characteristic histologic features are defined as follows: 1) cells with a moderate amount of cytoplasm resembling ground glass, 2) a fairly distinct cell membrane that stains with eosin or PAS, 3) large nuclei with prominent nucleoli. We present two cases of glassy cell carcinoma of the cervix successfullyl treated by neoadjuvant chemotherapy and radical hyterectorny, with a brief review of literatures.

OBJECTIVE: Carpal tunnel syndrome(CTS) is the most common entrapment neuropathy in the upper extremities. For the surgical treatment of CTS, endoscopic carpal tunnel release(ECTR) has been developed as a minimally invasive method, alternative to the open procedure over the past decade. The authors present clinical experience and surgical outcome of ECTR. METHODS: One hundred cases(34 right, 30 left and 19 bilateral hands) in 81 consecutive patients(mean age: 51.8 years, range: 33-77 years) with electrodiagnostically-proven CTS underwent a single-portal ECTR from January 2001 to December 2002. Preoperative clinical findings and results of electrodiagnostic studies were compared with surgical outcome respectively after 3-month-follow-up period. RESULTS: Among 100 cases 94(94%) were satisfied with complete or significant relief of symptoms and 6(6%) were dissatisfied with partial or no relief of symptoms. Major complications in 2 cases(one with ulnar nerve injury and the other one with ulnar artery laceration), developed in early experience of ECTR and recurrence in 1 case occured. Severity of electrodiagnostic abnormalities were correlated with surgical outcome but there's no statistical significance between them. Severity of clinical findings, age at onset and symptom duration were not correlated with surgical outcome respectively. CONCLUSION: ECTR is effective in relieving symptoms of CTS with a low complication rate after the learning curve period. Thus, ECTR can be the first procedure, alternative to the open surgery as an efficient, minimally invasive surgical technique for CTS.

Castleman's disease (CD) is an uncommon benign lymphoproliferative disorder of unknown etiology. Histopathologically, it is divided into three types: hyaline-vascular, plasma cellular, and multicentric CD. The mass usually presents asymptomatically; however, it can cause non-specific symptoms such as fever and fatigue. Although CD can be found wherever lymph nodes are present, 75% of cases are reported in the mediastinum, and occurrence in the head and neck is rare. Herein, we report a rare case of CD presenting as a superficial mass in the temporal region. To the best of our knowledge, this is the first report of temporal CD in Korea involving a young patient.

BACKGROUND: Patients who are considered for major pulmonary resection are generally evaluated by spirometry and clinical assessment to predict morbidity and mortality. Despite this, none has yet proved to be a convenient and reliable estimate of risk. MATERIAL AND METHOD: A retrospective analysis was performed in 167 patients who were diagnosed for lung cancer, bronchiectasis, pulmonary tuberculosis, and other benign pulmonary disease, and who underwent major lung resections. The relationship of 25 preoperative or postoperative variables to 19 postoperative events were classified into categories as operative mortality, pulmonary or cardiovascular morbidity, and other morbidity was assessed. Logistic regression analysis and x2 analysis were used to identify the relationship of the operative risk factors to the grouped postoperative complications. RESULT: The best single predictor of complications was the percent predicted postoperative diffusing capacity (pulmonary morbidity, p<0.009; cardiovascular morbidity, p<0.003: overall morbidity, p<0.004). CONCLUSION: The diffusing capacity of the lung for carbon monoxide was an important predictor of postoperative complications than the spirometry, and it usually should be a part of the evaluation of patients being considered for pulmonary resection.

BACKGROUND: Hibernoma is a rare benign tumor of adults that is composed of multivacuolated adipocytes resembling brown fat cells. Hibernoma typically occurs in soft tissue, and intraosseous examples are very rare. Intraosseous hibernomas can radiologically mimic metastatic carcinoma and other tumorous conditions. METHODS: To collect the intraosseous hibernomas, we searched the pathologic database and reviewed the hematoxylin and eosin (H&E)–stained slides of bone biopsy samples performed to differentiate radiologically abnormal bone lesions from 2006 to 2016. A total of six intraosseous hibernoma cases were collected, and clinical and radiological information was verified from electronic medical records. H&E slide review and immunohistochemical staining for CD68, pan-cytokeratin, and S-100 protein were performed. RESULTS: Magnetic resonance imaging of intraosseous hibernomas showed low signal intensity with slightly hyperintense foci on T1 and intermediate to high signal intensity on T2 weighted images. Intraosseous hibernomas appeared as heterogeneous sclerotic lesions with trabecular thickening on computed tomography scans and revealed mild hypermetabolism on positron emission tomography scans. Histopathologically, the bone marrow space was replaced by sheets of multivacuolated, foamy adipocytes resembling brown fat cells, without destruction of bone trabeculae. In immunohistochemical analysis, the tumor cells were negative for CD68 and pan-cytokeratin and positive for S-100 protein. CONCLUSIONS: Intraosseous hibernoma is very rare. This tumor can be overlooked due to its rarity and resemblance to bone marrow fat. Pathologists need to be aware of this entity to avoid misdiagnosis of this rare lesion.
