BACKGROUND: Nonrheumatic atrial fibrillation is common in elderly and associated with an increased risk for thromboembolism. Left atrial spontaneous echo contrast(SEC) and thrombus. which are easily detected by transesophageal echocardiography(TEE) in patients with rheumatic mitral valve disease and atrial fibrillation, have been known as markers of thromboembolism. However, most of the previous studies on left atrial SEC and thrombus were performed in rheumatic mitral valve disease or various conditions including rheumatic mitral valve disease. Therefore this study was underaken in order to investigatd 1) the prevalence of left atrial SEC and thrombus, and 2) clinical and echocardiographic variables related to left atrial SEC and thrombus in nonrheumatic atrial fibrillation. METHODS: In patients with estabished atrial fibrillation over 7 days, we examined the clinical gistory and performed transthoracic echocardiography(TTE) and TEE simultaneously. Enlisted patients were those without rheumatic mitral valve disease, prosthetic valves, previous thromboembolism, and recent anticoagulant therapy. RESULTS: 1) Left atrial SEC was detected in 32(62.7%) of 51 patients and left atrial thrombus in 10(19.6%). All thrombi were located in the left atrial appendage. 2) In univariate analysis, SEC positive group showed higher prevalence of congestive heart failure(CHF)(56.3% vs 0%, p<0.001), lower ejection fraction(42.2+/-14.1% vs 50.8+/-9.7%, p<0.05), lower left atrial appendage blood flow velocity(peak positive flow velocity ; 18.7+/-11.1cm/sec vs 32+/-12.4cm/sec, p<0.01, and peak negative flow velocity ; 21.4+/-12.4cm/sec vs 31.9+/-12.8cm/sec, p<0.01) than SEC negative group. Multivariate analysis identifed CHF as an independent variable related to left atrial SEC(p=0.02, Odds ratio ; 2.38, 95% CI ; 1.18-4.82). 3) In univariate analysis. left atrial thrombus positive group showed higher prevalence of CHF(70% vs 26.8%, p<0.05), larger left atrial demension(34+/-3.4mm/m2 vs 30.6+/-4.6mm/m2, p<0.05) than thrombus negative group. Multivariate analysis identifed CHF as an independent variable related to left atrial thrombus(p=0.04, Odds ratio ; 4.30, 95% CI ; 1.11-16.68). 4) Left atrial thrombus is more frequent in SEC positive group than in SEC negative group(28.1% vs 5.3%), however, there was no statistical significance(p=0.07). CONCLUSION: 1) Left atrial SEC is common in nonrheumatic atrial fibrillation and significantly related to CHF. 2) Left atrial thrombus is frequently detected in SEC positive patients, however, it is more realted to CHF than left atrial SEC itself.

BACKGROUND: Twenty-four-hour ambulatory blood pressure(ABP) monitoring has become increasingly popular for diagnosing and treating hypertension. Therefore the reference value of normotensive subjects was necessary for interpretation of hypertensive subjects. Several studies were reported on reference values in normotensive subjects. The purpose of this study was to determine 24-hour ABP in normotensive Korean adults stratified for sex and five age groups. This study also assessed ABP in relation to a family history of hypertension, smoking and body mass index(BMI). METHODS: ABP monitoring was performed in 200 healthy normotensive volunteers(ranged in age from 20 to 69 years, five decades, 20 men and 20 women per each decade), over 24 hours, taking measurement at 30-min intervals. The 24-hour interval was divided into day-time(6am-10pm) and night-time(100pm-6am) periods. Mean ABP and pressure loads(percentage of systolic readings>140mmHg, diastolic readings>90mmHg) were obtained. RESULTS: The mean ABP in 200 subjects was 113+/-8.6/72+/-6.9mmHg over 24 hours, 117+/-9.7/75+/-7.0mmHg during day-time, and 106+/-9.8/67+/-8.3mmHg at night-time, and pressure loadd averaged 5.1+/-7.4/7.9+/-8.9% over 24 hours. The +2 standard deviation(SD) as the upper limit of normal was 130/86mmHg over 24 hours in 200 subjects. The mean ABP and pressure load were 116+/-7.6/74+/-7.6mmHg and 6.4+/-8.3/10.1+/-10.2% in 100 subjects of men, and 110+/-8.3+/-70+/-6.6mmHg, 3.7+/-6.0/5.7+/-6.8% in women. Mean ABP and pressure load showed significant difference in relation to age group and sex, however, no significant difference in relation to a family history of hypertension or smoking. In relation to BMI group, diastolic blood pressure and diastolic pressure load were significantly different.

The branchio-oto-renal (BOR) syndrome is a clinically and genetically heterogeneous disease entity which is characterized by the association of preauricular pits, branchial cleft anomaly, hearing loss and various renal anomalies. The incidence of BOR syndrome is approximately 1 : 40,000 and its genetic pattern of transmission is autosomal dominant. Hearing loss is the most common feature of BOR syndrome and is reported in almost 90% of affected individuals. EYA1, the human homologue of the Drosophila eyes absent gene, has been shown to cause BOR syndrome. We report, with a review of literatures, a female patient with BOR syndrome.

Phenylpropanolamine is a sympathomimetic amine used widely as a decongestant or appetite suppressant. Reports of the myocardial injury from the use of phenylpropanolamine are rare and the mechanism of the myocardial injury is not known clearly. We experienced a case of myocardial injury after ingestion of phenyl-propanolamine. A 46-year-old woman was admitted because of chest pain and dyspnea after ingestion of 5 tablets of anorectic pill containing phenylpropanolamine 75 mg per tablet. The serum creatine kinase MB isoenzyme levels were elevated and electrocardiographic abnormalities suggesting myocardial infarction were seen in the precordial lead. In echocardiograpy, left ventricular anteroseptal wall motion was nearly akinetic but coronary angiography showed normal coronary arteries except sluggish blood flow in left anterior descending artery.

PURPOSE: To investigate the efficacy of amniotic membrane transplantation (AMT) in patients who were diagnosed with necrotizing scleritis after pterygium excision and who were refractory to systemic corticosteroid and immunosuppressive therapy. METHODS: Six patients who had persistent scleral melting with systemic corticosteroid or immunosuppressive agents underwent double AMT as a permanent patch graft and temporary overlying barrier. Postoperatively, the symptom improvements, reepithelization times and visual acuity changes were evaluated. RESULTS: Choroidal detachment was detected in two patients preoperatively. In all patients, ocular pain improved at 4.7 +/- 3.1 days, and reepithelization of the scleral lesions was completed at 13.2 +/- 8.1 days postoperatively. Choroidal detachment in two patients disappeared at postoperative 2 and 8 days. Complete remission was found in 5 of the 6 eyes (83.3%). One eye which achieved full epithelization in the necrotic area experienced recurrent nodular scleritis in another quadrant, resulting in remission after changing the regimen of immunosuppressive agents. Mean values of initial and final visual acuities were 0.898 logMAR and 0.428 logMAR, respectively, and the visual acuities improved in all patients. CONCLUSIONS: AMT is effective in promoting reepithelization of the necrotic area, resulting in complete remission of necrotizing scleritis in patients who were refractory to systemic corticosteroid or immunosuppressive therapy.

Lymphocytic interstitial pneumonia(LIP) is an uncommon condition in which the alveolar septa and extra-alveolar interstitial space are markedly expanded by small lymphocytes, plasma cells and histiocytes. Chest radiographs generally show nonspecific patterns with the most common pattern showing bibasilar reticular or reticulonodular infiltrates. Hilar or mediastinal lymphadenopathy and pleural effusions are usually absent. We encountered a 42-year-old female patient who was admitted to hospital because of exertional dyspnea and palpitation. The chest X-ray showed an enlarged bilateral hilar shadow and diffusely increased bronchovascular markings in both lung fields. The chest CT showed diffuse nodular infiltrations with mild septal thickening and combined patchy ground glass opacity in both lungs, and conglomerated mediastinal and bilateral hilar lymphadenopathy. A diagnosis of LIP was made from the tissue pathology taken by a thoracoscopic lung biopsy. The patient showed clinical and radiographic improvement after 3 months of treatment with prednisolone. We report a case of LIP presenting as diffuse nodular interstitial infiltrations with multiple mediastinal and bilateral hilar lymphadenopathy.

PURPOSE: We analyzed the medical costs for severely traumatized patients according to the severity and medical performance so that we couldimprove the financial balance of the trauma center. METHODS: Retrospective analysis was performed on patients visitingSNUH Trauma Center from May 2011 to August 2011. Among a total of 55 severely traumatized patients, 31 patients whose medical bills were available and categorized were included in this study. The injury severity score (ISS) was calculated from the abbreviated injury score (AIS), which was updated in 2008,for each patient to assess the severity of injury. Major trauma was defined as an ISS above 15. RESULTS: The 31 patients in this study included 20 males and 11 females. The average ISS was 33.23+/-16.65 points.We categorize the patients into three groups according to ISS, 16-24: group 1, 25-40: group 2, and above 41: group 3. Total incomes, admission fees, surgery fees, and imaging test fees are shown in table 1. The costs seem to be higher costs in group 2, but this result has no statistical significance. Statistical significantly data are as follows: high radiologic test fees in group 1, short hospital stay in groups 1 and 2, and short ICU stay in group 1. The averagehospital stay was 17 days, and the average emergency intensive care unit (EICU) stay was 7.5 days. Although the EICU stay was only 44% of the total hospital stay, the income from the EICU covers 79.4% of the total hospital income. CONCLUSION: From this study, we found several items that show relatively high medical income from severely traumatized patients visiting the SNUH Trauma Center. Most of the medical fees arise in the early phase of acute medicine usually in the ICU. Efforts to identify the items with high income and to minimize expenses will improve the financial structure of the Trauma Center,which is facing a budget crisis.
