This retrospective analysis describes the clinical characteristics, treatment, and long-term outcome of 30 patients with axis fracture admitted to our institution between January 1991 and December 1995. The incidence of axis fracture was 27.2% in the 110 cervical spine fractures. Among these, odontoid process fracture was the most common type, 19 cases(63%) followed by 8 hangmans fractures(27%), 3 miscellaneous fractures(10%). Hangman's fractures, odontoid type III fractures and miscellaneous fractures were treated with external immobilization devices. Remaining 11 odontoid type II fractures, and six patients with dens dislocation of 6 mm or greater were initially treated by early surgical stabilization. Individuals with dens dislocated less than 6 mm were treated by external immobilization only. Among the nonoperative group of acute axis fractures, there was no fusion failure. In the early operated group, all patients were stable clinically or radiologically. But three patients with posterior wiring and bone graft complained of their neck motion limitation.

The occurrence of a trigeminal neuropathy associated with connective tissue disease is rare. Trigeminal neuropathy in connective tissue disease is predominantly sensory and it is characterized by numbness, hypesthesia, slurred speech, and touch pain. Although the pathogenesis of trigeminal neuropathy associated with connective tissue disease remains obscure, the main pathologic findings are vasculitis and neuritis. A case of trigeminal neuropathy associated with mixed connective tissue disease is described, and the incidence, symptoms, pathophysiology, treatment of the disease is discussed.

Non-acetylated salicylates have been recommended for use as alternatives to nonsteroidal anti-inflammatory drugs (NSAIDs) in aspirin and/or tartrazine-sensitive patients. We experienced a case of an aspirin-sensitive asthmatic patient who developed a broncho-obstructive reaction after taking 100 mg of sodium salicylate. The result of this study suggests that sodium salicylate may cross-react with aspirin in aspirin-and tartrazine-sensitive patients.

BACKGROUND: Most febrile neutropenic patients are treated in an aggressive manner. However, identification of low-risk patients may enable clinicians to administer risk-based treatment. The object of this study is to certify the factors associated with increased risk at the time of visiting the emergency department. METHODS: This is a retrospective study. We reviewed the medical records of 101 febrile neutropenic patients who had visited the emergency department of Seoul National University Hospital from January 1998 to August 1999. We assumed 22 risk prediction factors that could be assessed at admission to the emergency department and 5 factors that could be assessed during treatment course. To find independent risk-prediction factors, we analyzed these factors respectively by using multiple regression analysis. RESULTS: Tachycardia(aOR=136.5), altered mentality(aOR=28.8), decreased renal function(aOR=20.1), and significant comorbidity(aOR=17.2) are the independent factors associated with higher mortality. Altered mentality(aOR=31.6) and decreased renal function(CCr<75ml/min, aOR=5.4) are those associated with a higher incidence of septic shock. Independent factors associated with persistent(more than 3 days) fever are the early(within 10 days) onset of fever after last chemotherapy(aOR=8.8) and the existence of new pulmonary infiltrates on a simple chest X-ray(aOR=4.3). CONCLUSION: The stability of vital signs, the change of mentality, the renal function, the existence of significant comorbidity, the existence of new pulmonary infiltrates, and the rate of neutropenia are clinically useful risk-predication factors in febrile neutropenia at the time of visiting the emergency department.

BACKGROUND: Because of the power of HRCT to detect the minute changes in lung parenchyme and the advantage of noninvasiveness, it may be the ideal method of follow-up evaluation of the patients with diffuse interstitial pulmonary fibrosis. So the aim of the study is to find out whether the change of HRCT during the course of the disease can represent the change in symptom and pulmonary function rest. METHODS: Thirteen patients with diagnosis of diffuse interstitial pulmonary fibrosis who had more than two times of HRCT during the course of disease were studied. The extent of the disease in HRCT was measured at three levels using image analyzer The ralationship between the percent change in the disease extent in HRCT, symptom score, and pulmonary function testis were analysed. RESULTS: The change of disease extent in HRCT has good correlation with the change in dyspnea and diffusion capacity(r=0.716, p=0.0012). But there was no correlation between the change of HRCT and FVC or TLC. Also significant inverse correlation was noted between the change in dyspnea and diffusion capacity(r=-0.707, p=0.0047). CONCLUSION: These data suggest that HRCT may be a good method of follow-up in diffuse interstitial pulmonary fibrosis.

BACKGROUND AND OBJECTIVES: The clinical pattern of infective endocarditis is constantly changing. Diagnosis and treatment of infective endocarditis were developed by recent diagnostic strategy (Duke criteria) and introduction of transesophageal echocardiography. The aim of this study was to compare the clinical character-istics of infective endocarditis in Sejong hospital to the previous report and was to investigate risk factor of heart failure, embolism and death. MATERIAL AND METHODS: All episodes hospitalized of infective endocarditis from January of 1990 to October of 1999 in Sejong hospital were reviewed retrospectively. The total cases of infective endocarditis was 80 cases in 78 patients. RESULTS: The male to female ratio was 1:1.05 (39 male, 41 female). The mean age was 42 years. Rheumatic heart disease was the most common predisposing heart disease in 28.8%, followed by prosthetic valve endocarditis. Streptococci were the most commonly isolated micro-organisms in 18 cases (45.0%), followed by staphylococci in 11 cases. Transesophageal echocardiography has a higher sensitivity than transthoracic echocardiography for detection of vegetation, abscess and paravalvular complication in endocarditis. In patients with echocardiographic vegetation and involvement of aortic valve, there was a statistically significant increase in the risk of heart failure. The factor that was associated with a statistically significant increase in the overall risk of embolization was not exist. Ten patients died (12.5%). Risk factor for death was left ventricular dysfunction. The incidence of death was more higher in patients with abscess and non-streptococcal endocarditis. CONCLUSION: Compared to the 1980's report, we observed increased mean age of patients, the decreasing trend of rheumatic heart disease as a predisposing heart disease and the decreasing incidence of streptococci as causative microorganism. Risk factors for congestive heart failure were aortic valve endocarditis and endocarditis with vegetation. Risk factor for death was left ventricular dysfunction.

PURPOSE: We previously reported results of a mean 3.2-year follow-up of the COREN hip system, which is the first total hip prosthesis developed in Korea. The aim of this prospective study was to update the previous report with regard to the hip function and radiographic implant performance. MATERIALS AND METHODS: Between 2003 and 2004, a consecutive series of 68 primary, cementless, total hip prostheses (COREN) were implanted in 57 patients(68 hips) and followed up for a minimum of 7 years. Sixty-three of the 68 hips were available for clinical scoring and radiographic analysis. RESULTS: The mean Harris hip and WOMAC scores were improved from 48.1 and 54.7, preoperatively, to 96.4 and 22.1 at the final follow-up. The mean patient activity increased from 3.1, preoperatively, to 8.2 at the final follow-up. All hips showed stable bony ingrowth on the radiographs. No hips showed evidence of osteolysis or prosthesis loosening, and no revision was required during the follow-up. A Periprosthetic fracture (Vancouver type B1) was encountered in one hip 4.7 years after surgery, which was treated by reoperation. CONCLUSION: This study shows that the COREN hip system produces excellent mid-term results in cementless hip arthroplasty.

Race and ethnicity are influential in estimating glomerular filtration rate (GFR). We aimed to find the Korean coefficients for the Modification of Diet in Renal Disease (MDRD) study equations and to obtain novel proper estimation equations. Reference GFR was measured by systemic inulin clearance. Serum creatinine (SCr) values were measured by the alkaline picrate Jaffe kinetic method, then, recalibrated to CX3 analyzer and to isotope dilution mass spectrometry (IDMS). The Korean coefficients for the 4 and 6 variable MDRD and IDMS MDRD study equations based on the SCr recalibrated to CX3 and to IDMS were 0.73989/0.74254 and 0.99096/0.9554, respectively. Coefficients for the 4 and 6 variable MDRD equations based on the SCr measured by Jaffe method were 1.09825 and 1.04334, respectively. The modified equations showed better performances than the original equations. The novel 4 variable equations for Korean based on the SCr measured and recalibrated to IDMS were 107.904xSCr-1.009xage-0.02 (x0.667, if woman) and 87.832xSCr-0.882xage0.01 (x0.653, if woman), respectively. Modified estimations of the MDRD and IDMS MDRD study equations with ethnic coefficients and the novel equations improve the performance of GFR estimation for the overall renal function.

BACKGROUND: To date, there are few data on the risk factors for severe cases and deaths associated with the 2009 pandemic H1N1 influenza A. Here, we describe the clinical and epidemiologic characteristics of patients hospitalized for pneumonia and identify those factors associated with the development of major complications (MC). METHODS: We reviewed the medical records of 41 cases of pneumonia admitted to a university-affiliated tertiary hospital between Aug 26 and Dec 10, 2009, and who had confirmed H1N1 influenza A based on real-time reverse transcriptase-polymerase-chain-reaction assay. There were 7,962 patients that fit these criteria. We compared the clinical features and demographic characteristics of patients who developed MC to with those who did not develop MC. RESULTS: During the study period, 10 patients developed MC (required admission to the intensive care unit, n=10; required ventilator therapy, n=6; death, n=4). Patients with MC were significantly older than those without MC and more frequently had underlying medical conditions (90.0% vs 41.9%, p-value <0.01). In the patients with developed MC, the median PaO2/FiO2 ratio of 230.0 (145.0~347.3) at admission and pneumonia severity index (PSI) score of 141.5 (88.3~158.5) were higher than patients without MC. However, no differences were observed in laboratory findings or in viral shedding between the 2 groups. CONCLUSION: In hospitalized pneumonia patients of 2009 H1N1 influenza, old age, a history of malignancy, initial hypoxemia, PaO2/FiO2 ratio, and PSI score appear to be risk factor significantly related to developing MC. These findings might be the basis to influence strategies for admitting patients to an intensive or intermediate care unit and for pre-emptive antiviral therapy.
