BACKGROUND AND OBJECTIVES:Although the various methods of pharyngolaryngeal closure after supraglottic partial laryngectomy(SPL) have been reported, the difference of postoperative function and complications has not been adequately analyzed. Therefore, We investigated the relationship between different pharyngolaryngeal closure methods and postoperative function and complications. PATIENTS AND METHODS: According to the methods of pharyngolaryngeal closure, postoperative complications, decannulation day and postoperative day when to start oral feeding were retrospectively investigated on 22 patients who underwent SPL. We divided the patients into two groups according to the methods of pharyngolaryngeal closure. In cartilage group(13 cases), the closure of pharyngolaryngeal defect was done with direct suture between the thyroid cartilage and base of the tongue. In perichondrial group(9 cases), the closure was done between preserved thyroid perichondrium and base of the tongue. RESULTS: There was no case requiring either a gastrostomy or a persistent tube feeding in our series. Fistula occurred more often in perichodrial group(3 cases) than cartilage group(0 case). In one case of perichondrial group, total laryngectomy was performed because of a fistula. Also, aspiration pneumonia occurred more often in perichodrial group(2 cases) than cartilage group(0 case). Decannulation could be performed relatively earlier in cartilage group than in perichondrial group. Also, oral feeding could be performed relatively earlier in cartilage group than in perichondrial group. CONCLUSION: Direct approximation between cut margin of the thyroid cartilage and base of tongue was safe, time-saving and reliable method of pharyngolaryngeal closure after SPL.

Objective:
The Delirium Diagnostic Tool-Provisional (DDT-Pro) was designed to detect the presence and severity of delirium briefly and objectively regardless of psychiatric expertise. We translated the DDT-Pro into Korean and validated it in elderly Korean patients.
Methods:
To validate the translation and evaluate inter-rater reliability, a psychiatric trainee and a research nurse independently assessed the same patients referred to the Department of Psychiatry. The results were compared with the reference evaluations performed by a psychiatrist using the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition (DSM-5).
Results:
We enrolled 42 elderly patients. The Cronbach’s alpha coefficient were 0.839 (the trainee), 0.822 (the nurse). The Cohen’s weighted κ between the trainee and nurse, ranged from 0.555±0.102 to 0.776±0.062. The Pearson correlation coefficients (Korean version of the DDT-Pro [K-DDT-Pro] and Korean version of the Delirium Rating Scale-Revised-98 [DRS-R98-K] total score) were γ=-0.850 (the trainee), and γ=-0.821 (the nurse). The areas under the ROC curves (AUCs) were 0.974 (the trainee) and 0.893 (the nurse).
Conclusion
The K-DDT-Pro exhibited high internal consistency and relatively substantial inter-rater reliability. The correlation with the DRS-R98-K was strongly negative. The accuracy of the K-DDT-Pro was excellent, regardless of expertise. In conclusion, the K-DDT-Pro is a brief and simple tool that usefully screens for delirium in elderly patients.

BACKGROUND: Postoperative spinal epidural hematoma (POSEH) is different from spontaneous or post-spinal procedure hematoma because of the application of suction drains. However, it appeared that suction drains were not effective for prevention of POSEH in previous studies. The purpose of this study was to test our hypothesis that POSEH can be caused by hypercoagulability. METHODS: This was an experimental study. One hundred fifty milliliters of blood was donated from each of the 12 consecutive patients who underwent spine surgery and infused into 3 saline bags of 50 mL each. One of the 3 bags in each set contained 5,000 units of thrombin. All of them were connected to 120 ± 30 mmHg vacuum suctions: drainage was started 8 minutes after connection to the vacuum system for 12 normal blood bags (BV8) and 12 thrombin-containing blood bags (TBV8) and 15 minutes after connection for the remaining 12 normal blood bags (BV15). The amount of initial and remaining hematoma at 20 minutes, 120 minutes, and 24 hours after vacuum application were measured by their weight (g). The primary endpoint was the difference between BV8 and TBV8. The secondary end point was the difference between BV8 and BV15. RESULTS: The remaining hematoma in TBV8 was significantly greater than that in BV8 at all measurement points: 46.3 ± 12.4 vs. 17.0 ± 1.3 (p = 0.000) at 20 minutes; 33.0 ± 8.2 vs. 16.3 ± 1.2 (p = 0.000) at 120 minutes; and 26.1 ± 4.0 vs. 15.8 ± 1.6 (p = 0.000) at 24 hours after vacuum application. The remaining hematoma of BV15 was significantly greater than that of BV8 at all measurement points: 30.0 ± 12.0 vs. 17.0 ± 1.3 (p = 0.002) at 20 minutes; 24.2 ± 7.6 vs. 16.3 ± 1.2 at 120 minutes (p = 0.002); and 22.2 ± 6.6 vs. 15.8 ± 1.6 (p = 0.004) at 24 hours after vacuum application. CONCLUSIONS: With a suction drain in place, the amount of remaining hematoma could be affected by coagulability. Thrombin-containing local hemostatics and the length of time elapsed before the commencement of suction resulted in hypercoagulability, indicating these two factors could be causes of POSEH.

Acute necrotizing esophagitis (AEN), also called "black esophagus," is a rare disorder with an unknown pathogenesis. Endoscopic findings generally show black pigmentation throughout the esophagus. This case also offered rare views of the gross anatomy of this disorder. Histological examination revealed that the mucosal and submucosal layers of the esophagus were involved in the severe necrotizing inflammation. The chief manifestation of this disease is hematemesis from hemorrhage of the upper gastrointestinal tract with a typically multifactorial etiology. AEN is also characterized by a clear boundary at the gastroesophageal junction where the necrosis stops. In this study, we report an autopsy case of a 61-year-old man with necrotizing inflammation throughout the esophagus and esophageal necrosis from the laryngopharynx to the gastroesophageal junction. The patient was a disabled person with a history of alcohol abuse who was also diagnosed with mild coronary arteriosclerosis and fatty liver on the basis of the underlying diseases. In this case, the main etiology for poor perfusion from the distal esophageal area was likely underlying illness, history of alcoholism, and malnutrition.

Hemophagocytic Syndrome (HS) is a systemic lymphohistiocytic proliferative disorder associated with infection or malignancies, particularly Epstein-Barr virus (EBV) HS is presented with high fever, skin rash, hepatosplenomegaly, and cytopenia. The characteristic pathologic finding is massive lymphohistiocytic infiltration with hemophagocytosis in various organs including bone marrow, liver, and spleen. Hyperproduction of cytokines by activated T lymphocytes has been presumed to account for the hemophagocytosis and clinical manifestations of HS. We report three childhood autopsy cases with HS which was confirmed by histopathologic examination. According to medical records, all cases had high fever with or without skin rash, cytopenia, AST/ALT elevation, and hyperfibrinogenemia, and showed multiple organ failure eventually. At autopsy, there were no specific gross findings except splenomegaly, but extensive lymphohistiocytic infiltration with hemophagocytosis was seen in various organs including lymph nodes, spleen, liver, and bone marrow. In one of three cases, EBV was identified with in situ hybridization method. As this disease has rapidly progressive clinical course with fatal outcome during childhood, so the possibility of HS should be considered in children presenting with high fever and hepatosplenomegaly.

Necrotizing bronchial aspergillosis usually occurs in the immumocompromised host. Aspergillus invades bronchial epithelium and forms endobronchial mass or endobronchial stenosis. A 78-year-old male patient with diabetus mellitus complaining of dyspnea and cough was admitted to our hospital. Plain chest X-ray and chest computed tomogram showed a large endobronchial mass and total collapse of left upper lobe of the lung. Bronchoscopic biopsy of the endobronchial mass revealed chronic inflammation. To confirm the endobronchial mass, we performed sleeve lobectomy of left upper lobe of the lung. Histologically the mass was diagnosed as necrotizing bronchial aspergillosis. We report a case of necrotizing bronchial aspergillosis in an elderly man who has diabetus mellitus with review of the literature.

BACKGROUND: Acute pulmonary thromboembolism is fatal because of abruptly occurring hypoxemia and right ventricular failure. There are several treatment modalities, including anticoagulation, thrombolytics, ECMO (extracorporeal membrane oxygenator), and thromboembolectomy, for managing acute pulmonary thromboembolism. MATERIALS AND METHODS: Medical records from January 1999 to December 2004 at our institution were retrospectively reviewed for pulmonary thromboembolectomy. There were 7 patients (4 men and 3 women), who underwent a total of 8 operations because one patient had post-operative recurrent emboli and underwent reoperation. Surgery was indicatedfor mild hypoxemia and performed with CPB (cardiopulmonary bypass) in a beating heart state. RESULTS: The patients had several symptoms, such as dyspnea, chest discomfort, and palpitation. Four patients had deep vein thromboembolisms and 3 had psychotic problems, specifically schizophrenia. Post-operative complications included hemothorax, pleural effusion, and pericardial effusion. There were two hospital deaths, one each by brain death and right heart failure. CONCLUSION: Emergency operation should be performed when medical treatments are no longer effective.

The synchronous double cancer of the esophagus and lung is rare. Right lower lobectomy and Ivor Lewis procedure were performed simultaneously in a 75 year-old male patient who had synchronous double primary squamous cell carcinoma of the thoracic esophagus and right lower lobe of the lung. Left upper lobectomy was performed in a 69 year-old male patient who had squamous cell carcinoma of the left upper lobe of the lung, and four months later we performed Ivor Lewis procedure for the squamous cell carcinoma that occurred in the thoracic esophagus. The above two patients were doing well 10 months and 24 months after the operation respectively without recurrence. We treated the two cases of synchronous double cancer of the esophagus and lung with complete resection, and report this with review of literature.

A 30 year-old female patient was admitted for dizziness and palpitation. Pulsation of the both upper extremities and both common carotid arteries were absent. Innominate artery and both common carotid arteries were severely narrowed, and both subclavian arteries were completely obstructed on aortogram. The patient was diagnosed as type I Takayasu's arteritis, and operation was performed to increase blood flow to the brain and both upper extremities. Ascending aorta, both carotid arteries, both subclavian arteries, and both axillary arteries were exposed by four separate incision, and we performed an aorto-bicarotid-biaxillary bypass with Hemashield graft. Previous dizziness and palpation were disappeared after the operation.

Primary pulmonary arterial sarcomas, especially those originating from the pulmonary valve are extremely rare. A 35 year-old male patient was admitted for exertional dyspnea and fatigue. Large intraluminal mass in the main pulmonary artery and both pulmonary arteries was detected by chest computed tomogram, chest magnetic resonance imaging, echocardiogram, and pulmonary angiogram. We regarded the mass as a primary pulmonary arterial malignant tumor, and resected under cardiopulmonary bypass. The mass was appeared to originate from the posterior cusp of pulmonary valve, and extended from below pulmonary valve to main pulmonary artery and both pulmonary arteries. We resected the mass by pulmonary endarterectomy and replaced the pulmonary valve. The mass was diagnosed as a pulmonary arterial sarcoma in histopathologic examination.
