Relevance of Seizure with Mortality and Neurologic Prognosis of Out of Hospital Cardiopulmonary Arrest (OHCA) Patients Who had Treated with Therapeutic Hypothermia after Return of Spontaneous Circulation

PURPOSE: The purpose of this study is to evaluate relevance of postanoxic seizure with prognosis in cases of out-of hospital cardiac arrest (OHCA) patients treated with TH and to research the prognostic role of portable electroencephalography (EEG). METHODS: A total of 180 OHCA patients arrived during July of 2008 and June of 2011, and 144 patients who had been treated with therapeutic hypothermia were included in this study. Portable EEG was taken 24 hours after induction of TH and classified by the attending neurologist. As an outcome variable, overall mortality and neurological outcome after six months from discharge were evaluated (Good neurological outcome; Cerebral performance category (CPC) scale 1, 2, Poor neurological outcome; CPC scale 3~5). RESULTS: Among 144 patients, 93 patients (63.9%) were male, and mean age was 51. Eighty two patients (56.9%) survived and almost 30% (43/144) of patients had a good neurological outcome. Sixty five patients (45.1%) had seizures, and, among this group, 19 patients (29.2%) were discharged with a good neurological outcome. No statistical difference was observed between the seizure group and the non-seizure group. Initial rhythm, APACHI II score, and time from basic life support to return of spontaneous circulation (OR, 2.169; 95% CI, 1.158~4.063, OR 1.107; 95% CI 1.064~1.152, OR 1.014; 95% CI 1.006~1.022, respectively) showed statistical importance, however, the seizure group (OR, 0.67, 95% CI, 0.356~1.032, p=0.065) had no statistical relevance with mortality. Grading of EEG by the neurologist showed a positive association with neurological outcomes (p<0.001). Factors associated with good neurological outcome were VF/VT initial rhythm (p=0.005), cardiac cause of arrest (p=0.001), high initial body temperature (p<0.001), low APACHI II score (p=0.010), and shorter time interval between arrest from basic life support (p=0.005). CONCLUSION: In our study, the seizure group showed no relevance with mortality and prognosis. In hope of achieving a better outcome, careful treatment should be provided in cases of OHCA patients with seizure. Conduct of larger, prospective studies is needed.

Development and Evaluation of Validity of Dish Frequency Questionnaire (DFQ) and Short DFQ Using Na Index for Estimation of Habitual Sodium Intake / 대한지역사회영양학회지

The assessment of sodium intake is complex because of the variety and nature of dietary sodium. This study intended to develop a dish frequency questionnaire (DFQ) for estimating the habitual sodium intake and a short DFQ for screening subjects with high or low sodium intake. For DFQ112, one hundred and twelve dish items were selected based on the information of sodium content of the one serving size and consumption frequency. Frequency of consumption was determined through nine categories ranging from more than 3 times a day to almost never to indicate how often the specified amount of each food item was consumed during the past 6 months. One hundred seventy one adults (male: 78, female: 93) who visited hypertension or health examination clinic participated in the validation study. DFQ55 was developed from DFQ112 by omitting the food items not frequently consumed, selecting the dish items that showed higher sodium content per one portion size and higher consumption frequency. To develop a short DFQs for classifying subjects with low or high sodium intakes, the weighed score according to the sodium content of one protion size was given to each dish item of DFQ25 or DFQ14 and multiplied with the consumption frequency score. A sum index of all the dish items was formed and called sodium index (Na index). For validation study the DFQ112, 2-day diet record and one 24-hour urine collection were analyzed to estimate sodium intakes. The sodium intakes estimated with DFQ112 and 24-h urine analysis showed 65% agreement to be classified into the same quartile and showed significant correlation (r = 0.563 p < 0.05). However, the actual amount of sodium intake estimated with DFQ112 (male: 6221.9 mg, female: 6127.6 mg) showed substantial difference with that of 24-h urine analysis (male: 4556.9 mg, female: 5107.4 mg). The sodium intake estimated with DFQ55 (male: 4848.5 mg, female: 4884.3 mg) showed small difference from that estimated with 24-h urine analysis, higher proportion to be classfied into the same quartile and higher correlation with the sodium intakes estimated with 24-h urine analysis and systolic blood pressure. It seems DFQ55 can be used as a tool for quantitative estimation of sodium intake. Na index25 or Na index14 showed 39~50% agreement to be classified into the same quartile, substantial correlations with the sodium intake estimated with DFQ55 and significant correlations with the sodium intake estimated with 24-h urine analysis. When point 119 for Na index25 was used as a criterion of low sodium intake, sensitivity, specificity and positive predictive value was 62.5%, 81.8% and 53.2%, respectively. When point 102 for Na index14 was used as a criterion of high sodium intake, sensitivity, specificity and positive predictive value were 73.8%, 84.0%, 62.0%, respectively. It seems the short DFQs using Na index14 or Na index25 are simple, easy and proper instruments to classify the low or high sodium intake group.

Depression and Dietary Factors Related to Hyperlipidemia in Urban Living Elderly Female from Low Income Group / 대한지역사회영양학회지

We conducted a case-control study to examine the relationship of depression and dietary related factors with the hyperlipidemia for urban living elderly women from low income group. The case group consisted of 45 elderly females with hyperlipidemia (serum cholesterol > or = 240 mg/dl or serum TG > or = 250 mg/dl) and the control group of 95 age matched elderly women with serum cholesterol levels less than 240 mg/dl and serum TG less than 250 mg/dl. In a univariate analysis, vitamin C intake, the number of family members living with the subject, and their depression scores were significantly higher in the hyperlipidemic group than in the control group. In the logistic regression analysis, the vitamin C intake (> or = 75% Korean RDA), the number of family members living with the subject (> or = 1), depression scores (> or = 7), BMI (> or = 27), and subscapular skinfold thickness (> or = 18 mm) were associated with significantly higher (p or = 7 ; 95%CI : 1.10 - 5.60) and subscapular skinfold thicknesses (Odds Ratio 5.69 for SBT > or = 18 mm ; 95%CI : 1.87 - 17.32) were the significant risk factors associated with hyperlipidemia in the elderly women.

A Case of Acute Mediastinitis Associated with Fish Bone with Successful Conservative Treatment / 결핵

Acute mediastinitis is a life threatening disorder that causes severe morbidity in affected patient. We experienced a case of acute mediastinitis in a 56 year-old man as a result of swallowing a fish bone (Order Perciformes, Family Pomacentridae). Conservative treatment, including starvation therapy and the injection of antibiotic drugs, were successful in treating this patient. Although the optimal treatment for acute mediastinitis remains controversial, it is important to choose the appropriate strategies when encountering cases of acute mediastinitis.

Left Lower Lobectomy with Bronchoplasty for Treatment of Bronchial Stricture / 대한흉부외과학회지

A case of endobronchial tuberculosis with left main bronchial stenosis and atelectasis of left lower lobe in a 26-year-old female is reported. She had taken antituberculous agents for 9 months, but she complained of chest pain and coughing. Bronchoscopy revealed patency of left upper bronchus and bronchiectasis of left lower lobe. She underwent left lower lobectomy with bronchoplasty. After the operation she had significant improvement of pulmonary function. Although surgical treatment of endobronchial tuberculosis is controversial, bronchoplastic surgery can be an effective treatment of tuberculous bronchial stenosis because it relieves patients from symptoms by preserving lung functions.

Extralobar Pulmonary Sequestration located in Right Oblique Fissure with Unusual Vascularture / 대한흉부외과학회지

Pulmonary sequestration is an abnormal lung tissue that does not communicate with tracheobronchial tree, and that receives blood supply from anomalous arteries. Pulmonary sequestration is divided into two anatomical forms, intralobar and extralobar. Extralobar pulmonary sequestration is usually located between the diaphragm and the lower lobe and has systemic arterial supply and venous drainage, and most patients are diagnosed in their infancy. We report an extralobar pulmonary sequestration located between the right upper lobe and the lower lobe in a 48-year-old female adult, which has anomalous blood supply from the right pulmonary artery and venous drainage directly into the left atrium.

Diaphragmatic Hernia as a Complication of Pedicled Omentoplasty / 대한흉부외과학회지

Pedicled omentoplasty is effective in thoracic surgery, but it is associated with several postoperative complications. A case of diaphragmatic hernia as a complication of pedicled omentoplasty in a 65-year-old male is reported. Because aortoesophageal fistula occurred three months after the patch aortoplasty for mycotic aneurysm of descending thoracic aorta, he underwent ascending thoracic aorta to abdominal aorta bypass surgery with resection of thoracic aortic aneurysm and esophagorrhaphy with wrapping of the esophageal suture line and the stumps of aorta with pedicled omental flap. Three years after the operation, herniation of the stomach developed. The pedicled omental flap was ligated and divided, and the diaphragm defect was repaired.

Endoscopic Treatment of Latrogenic Chylothorax after Thoracic Symphathicotomy: A Case Report / 대한흉부외과학회지

Endoscopic symphathicotomy is an effective treatment for hyperhidrosis. Chylothorax is a rare but life-threatening complication. We recently encountered a case of chylothorax after endoscopic symphathicotomy at T2-T4 symphathetic nerve. We successfully treated chylothorax by electric cauterization with thoracic endoscopy.

Unusual Phenotype Expression in a Cis-AB Trait: Cis-AB Child from a Group A Father and a Group O Mother / 대한수혈학회지

Cis-AB (A2B3) is a rare genotype resulting from the inheritance of both A and B genes on one chromosome. Among possible genotypes of cis-AB, in individuals with O/cis AB and A1/cis-AB, the B antigen is usually weakly expressed. Study on a blood sample from a 13-year-old Korean girl showed a discrepancy between red blood cell and serum typing. The blood type was identified as AweakB on the red cell test, while weak anti-B was detected in the serum. Cis-AB (A2B3) was suspected, however, known blood types of her father and mother were A and O, respectively. In the repeated test, the propositus was typed as group A2B3. Her mother was typed as normal group O. Her father was typed as group A1 in cell typing, but in his serum, anti-B was very weakly detected. In the saliva test and adsorption and elution studies of the father, B substance was not detected. Finally, ABO genotyping was performed and ABO genotypes of the patient, mother and father were cisAB/O, O/O and cisAB/A1, respectively. This was the first reported case of A1/cisAB with phenotype A1. ABO genotyping technique will resolve problems encountered in association with unusual phenotype expression of cis-AB trait.

Results of Arteriovenous Fistula Revision in the Forearm / 대한흉부외과학회지

BACKGROUND: Because the development of medicine, the survival of ESRD(end stage renal disease) patients were improved and the chance of secondary arteriovenous fistula formation was increased. The purpose of this study is to evaluate the patency rate of one of the secondary arteriovenous fistula formation. MATERIAL AND METHOD: From January 1995 to September 1998, arteriovenous fistulae were made in 365 patients with ESRD. Among them, 62 patients underwent revisional arteriovenous fistula. RESULT: The patency rate for revisional arteriovenous fistula was 78.8% at 6 months, 72% at 12 months, 63% at 24 months, 56.9% at 36 months. CONCLUSION: Revision is a reliable procedure for salvaging a failed and inadequate fistula, which yields an acceptable patency rate.

Aortoesophageal Fistula after Prosthetic Patch Aortoplasty for Mycotic Aneurysm of the Descending Thoracic Aorta / 대한흉부외과학회지

Aortoesophageal fistula is an uncommon and fatal complication after surgery of aortic aneurysm. A case of aortoesophageal fistula as a complication of synthetis patch aortoplasty for mycotic aneurysm of descending thoracic aorta is described. After 3 months since patch aortoplasty for mycotic aneurysm of descending thoracic aorta this patient visited the emergency room due to melena and hematemesis. After gastrofiberoscopy and computed tomography the patient was taken ot the operating room. The surgical intervention was performed in two steps. Median sternotomy and midline laparotomy were made. Hemashield's Dacron(16mm) bypass between ascending thoracic aorta and infra-renal abdominal aorta was established first. Through the posterolateral thoracotomy false aneurysm and previous Hemashield's Dacron patch of descending aorta were resected. The two ends of the aorta were sutured and esophageal fistula was repaired. The esophageal suture line and the stumps were covered with omental graft. Thirty months later the patient has had no difficulty referable to the aortic surgery.

Intrapulmonary and gastric teratoma : report of two cases

The lung and stomach are very unusual sites for teratoma. The histologic findings of intrapulmonary and gastric teratomas are not different from those arising in usual sites, such as the ovary or testis. However, preoperative diagnosis is sometimes difficult to make partly because of unusual location. We report here two cases of teratoma, one intrapulmonary teratoma and the other gastric. The intrapulmonary teratoma in our study had an endobronchial tumor growth, which rules out mediastinal teratoma. Meanwhile gastric teratomas usually present as a submucosal tumor and most cases are reported in infancy and childhood. Gastric teratoma in this study occurred in a 27-year-old man. To the best of our knowledge, this case of intrapulmonary teratoma is the eighth and the gastric teratoma is the first to be reported in Korea.

Surgical Treatment of the Descending Thoracic Aorta: An analysis of 22 cases / 대한흉부외과학회지

BACKGROUND: The purpose of this study was to evaluate and analyze the surgical techniques and postoperative complications in patients undergoing operations for descending thoracic aortic aneurysms. MATERIAL AND METHOD: The data of 22 major operations between March 1987 and August 1997 were retrospectively reviewed. RESULT: There were 18 men and 4 women with a mean age of 49 years (range 33 years to 82 years). The cause of the aneurysm was aortic dissection in 13 patients, atherosclerosis in 3, mycotic in 3, trauma in 2 and uncertain in 1. The operative techniques were resection and graft replacement in 16, axillofemoral bypass graft in 2, femorofemoral bypass graft in 2, exclusion, aneurysmorrhaphy in 1 and transfemoral stent insertion in 1. During the operation, 16 cases were performed under total aortic clamp. Among the 16 patients, femorofemoral bypass was used in 14 cases and previously made shunt in 2 cases. The mean total aortic clamp time was 91 minutes and the mean extracorporeal circulation time was 116 minutes. One death occurred in an excluded patient on the 52 postoperative day due to a rupture of the aneurysm. Postoperative complications were paraplegia in 1 case, acute renal failure in 1 case and acute respiratory failure in 1 case. CONCLUSION: Although surgical treatment of the descending thoracic aneurysm has many postoperative complications, good surgical results can be achieved with a proper patient selection and fine surgical techniques.

Embolectomy of Arteries of Extremities: Clinical analysis of 26 cases / 대한흉부외과학회지

We present a retrospective analysis of arterial embolectomies performed at the Inje University Seoul Paik Hospital. During the period of March 1987 - Feburary 1996 twenty-six patients underwent embolectomies, eighteen patients were male and eight patients were female, mean age of patients was 56.8 years. Rest pain was the chief complaint in 24 patients, the remaining two patients complained of long term history of claudication after recovery of acute symtoms. But only 10 patients had sensory/motor symtoms. Heart was the most common source of embolization and frequent predisposing factor of embolism was ischemic heart disease in 8 cases and valvular heart disease in 11 cases. The sites of embolization were upper extremities artery in 6 cases, saddle embolism in 2 cases, lower extremities artery in 18 cases and the most common site of embolism was femoral artery in 11 cases. Preoperative angiography was taken in the diagnosis and planning of the embolectomy in 13 patients while in the other patient preoperative angiography was not taken. Only two cases were operated within the golden period of 6 hours and other cases were operated in more than 6 hours after embolization. In all patients, the Fogarty embolectomy catheter was used without bypass surgery via bachial ateriotomy in the embolism of upper extremities artery, bilateral groin approaches in the saddle embolism and transfemoral approach in the embolism of lower extremities artery. However 3 patients were re-operated via transpopliteal approach in the distal poplitiotibial embolism. Eighteen patients received perioperative anticoagulation therapy by heparin or fraxiparine and wafarin was used in 17 patients at the time of discharge and the indication of anticogulation was patients of valvular heat disease and/or atrial fibrillation, peripheral artery atherosclerosis and recurrent embolism. Postoperative results of the embolectomy were as follows: fouteen pateints had excellent results, five cases had symtom improvement after re-operation, B.K. amputation in 1 case who had sever atherosclerosis of lower extremities, recurrent embolism in 1 case and death in 2 cases the cause of death were acute renal failure and cerebral artery embolism, respectively. The complications of the embolectomy were reperfusion syndrome, pseudoaneurysm and intimal dissection in one case each. Conclusively the problems of embolism is delayed diagnosis and increasing number of old aged patient who had suffered ischemic heart diease. Preoperative angiography was not always needed for embolectomy. Selective anticoagulation therapy can decrease incidence of re-embolism. In the distal poplitiotibial embolism, seletive embolectomy of tibial artery was difficult.

Esophageal Reconstruction for Hypopharyngeal Stricture After Severe Corrosive Injury / 대한흉부외과학회지

Between 1987 and 1995, eleven patients with severe chronic corrosive stenosis of the hypopharynx and esophagus underwent surgical restoration of digestive continuity at Inje University Seoul Paik Hospital. There were 7 male and 4 female patients aged from 21 to 47 years (mean, 34 years). The caustic material was acid in 6 patients and alkali in 5 patients. The esophagus was reconstructed using the right colon in 9 and left colon in 2. The cervical approach and the side of proximal anastomosis depended on the status of the pyriform sinus of the hypopharynx. In the neck, J-formed incision was made along the sternocleidomastoid muscle. The sternohyoid and thyrohyoid muscles were divided transversely to expose the thyroid cartilage. Hypopharyngeal opening for proximal anastomosis was made by reverse triangular formed resection of the thyroid cartilage after elevation of perichondrium. Immediately after operation, dysphagia and aspiration into trachea were common, so training of swallowing was required. Feeding gastrostomy was usually maintained for 3 months until restoration of swallowing function was confirmed. There was graft necrosis in 3 patients, who were treated with jejunal free graft. Revisional procedures for stenosis of cervical anastomosis in 3 patients consisted of widening of pharyngocecostomy site in 2 and resection of adhesive band in one. Return of normal swallowing assuring normal nutrition was obtained in 10 of 11 cases.

Clinical Analysis of Primary Mediastinal Tumors / 대한흉부외과학회지

We reviewed 40 cases of primary mediastinal tumors which were operated on at Seoul Paik Hospital from September, 1987 to December, 1995. Of these, 18 were male and 22 were female. The patient ranged in age from 4 years to 68 years with a mean age of 34.1 years. The most common symptoms included chest pain(12.5%), cough(12.5%), dyspnea(7.5%), and palpable neck mass(7.5%), and symptoms were absent at the time of diagnosis in 37.5% of cases. Chest roentgenography and computed tomography(CT) were performed in all patients, and magnetic resonance imaging(MRI) in 5 patients, and transthoracic needle aspiration (TTNA) performed in 22 patients. The sensitivity of TTNA was 72.7%(16 of 22 patients). The lesion was located 60% in the anterosuperior mediastinum, 35% in the posterior mediastinum, and 5% in the middle mediastinum. The primary tumors included thymic neoplasms(11 cases), germ cell tumors(7 cases), neurogenic tumors(10 cases) and a miscellaneous group. The malignant tumors(12.5%) were invasive thymoma(3 cases), spindle cell sarcoma(1 case), and non-Hodgkin's lymphoma(1 case). A complete excision was done in all 35 benign tumors and 3 malignant tumors. There was no operative mortality, and postoperative complications occurred in 3 cases.

Mycotic Aneurysm of the Superior Mesenteric Artery: Report of 2 Cases / 대한흉부외과학회지

We have experienced two cases of mycotic aneurysms of the superior mesenteric artery. The first case originated from septic embolism of infective endocarditis and the second case originated from salmonella enteritis eight months before. The aneurysms were diagnosed by abdominal ultrasonography and comfirmed by computed tomogram and angiography but the blood culture was negative in both cases at the time of the surgery. Both patient were successfully treated by resection only and the restorations of vascular continuity were not neccesary because of adequate collateral circulations to the intestine. Both patient's postoperative courses were uneventful after the follow up of one year and nine months, respectively.

Ruptured Aneurysm of Descending Thoracic Aorta due to Salmonella Arteritis: 1 case report / 대한흉부외과학회지

A very rare case of mycotic aneurysm in the descending thoracic aorta due to salmonellosis was treated in our hospital. The patient was a 62 year-old male who 48 days before the operation was admitted to the department of internal medicine complaining of fever, nausia, vomiting, and loose stool. He was treated for 35 days and discharged. Three days after discharge, however, the patient was readmitted to the hospital complaining of right upper quadrant abdominal pain. Fever developed on the third hospital day, and on the eighth hospital day, the patient complained of back pain and epigastric pain. A simple chest x-ray showed evidence of hemothorax in the left plueral space, and therefore, computed tomography of the chest was done. The patient was diagnosed as a ruptured mycotic aneurysm of the descending thoracic aorta, and was transferred to our Department of Thoracic and Cardiovascular Surgery. The aneurysm and infected tissues was widely debrided, and the site was then patched with a Dacron graft. Salmonella choleraesuis was identified in the blood and aneurysm cultures, and antibiotics were administered for 6 weeks according to the sensitivity of the organism. The patient experienced no complication thereafter and for the last three months since the operation, he has been leading a healthy and normal social life.

Malignant Solitary Fibrous Tumor of the Pleura in Mediastinum

Solitary fibrous tumors (SFTs) most often involve the pleura and also may encompass the peritoneum and nonserosal sites. They occur as solitary encapsulated tumors and pursue a relatively benign clinical course. The usual criteria for malignancy are high cellularity, mitotic activity (more than 4 per 10 high-power fields), cellular pleomorphism, hemorrhage and necrosis as well as infiltrative growth. We report a case of malignant SFT of pleura who presented with an anterior mediastinal mass. Grossly, it was a 10x8x6.5 cm sized, encapsulated and well-demarcated, solid neoplasm with areas of extensive necrosis. Microscopically, parallel or haphazard arrangement of spindle cells with variable degrees of collagenous background were noted. Storiform fascicle formation, hemangiopericytoma-like pattern, and epithelioid cell clusters were often intermingled. Nodular areas with high cellularity and mitotic activity (> or =10/10 HPFs) were scattered throughout the neoplasm, however no definite cellular pleomorphism was encountered. Tumor cells were immunoreactive for vimentin and CD-34, which distinguished them from the mesothelial cells. Electron microscopically, they revealed fibroblastic and myofibroblastic differentiation.
