STUDY DESIGN: This study reviewed 20 patients who were diagnosed as internal disc disruption (IDD) of the cervical spine. Clinical symptoms were analyzed retrospectively. OBJECTIVES: To assess the various symptoms of IDD of the cervical spine. Summary of Literature Review : Several studies have demonstrated the symptoms of lumbar spine IDD. No studies have attempted to show the symptoms of cervical spine IDD. MATERIALS AND METHODS: A group of patients, who showed chronic neck pain and referred pain to upper limbs after a certain trauma, was materials of this study. All these patients were examined with simple X-ray, flexion-extension views, magnetic resonance image (MRI). When intractable pain was prolonged over 6months in spite of conservative treatment, patient was admitted and performed discogram and computed tomograpy (CT) for a definite diagnosis. There were 20 patients who were diagnosed as IDD from July 1996 to June 2001, and clinical symptoms were analyzed retrospectively. RESULTS: The various symptoms of the IDD of the cervical spine were chronic neck pain (100%), shoulder pain (95%), headache (90%), interscapular pain (80%), arm pain and paresthesia (75%), insomnia (75%), hand pain and paresthesia (60%), periocular pain (60%), forearm pain and paresthesia (50%), chin pain (50%), subjective weakness of upper extremity (45%), periauricular pain (40%) and tinnitus (30%). CONCLUSION: We are led to believe that patients who have chronic neck pain, shoulder pain, interscapluar pain, and other symptoms after a certain trauma of cervical spine are clinically diagnosed as IDD of the cervical spine, although X-ray and MRI are normal. Definite diagnosis of these patients would be made by a discogram, if similar or identical pain is provocated.

As the elderly population increases, the incidence of lumbar fusion is increasing, and there has been increasing interest in rapid rehabilitation and functional recovery after surgery. Enhanced recovery after surgery program and multimodal pain control methods can reduce the complications and allow rapid recovery. Various methods have been used to increase the fusion.

BACKGROUND: The nature of depressed left ventricular ejection performance in chronic pressure-overload hypertrophy due to aortic stenosis is controversial. Patients with aortic stenosis and congestive heart failure who responded well and those who responded poorly to aortic valve replacement may represent two distinct groups, rather than opposite ends of a spectrum. Whereas excess afterload accompanied by inadequate hypertrophy of functioning cardiac muscle was been suggested as the cause of impaired left ventricular shortening, intrinsic depression of contractility of the hypertrophied myocardium was also been considered, at least in part, to be the cause of altered ejection performance. METHOD: We studied 20 patient with non-rheumatic aortic stenosis using echocardiogram and cineangiocardiography. The patients were divided into two groups according to the level of LVEF and New York Heart association [NYHA] functional class. In group 1, 7 patients had an echocardiographically determined LVEF less than 40% and clinical presentation of severe congestive heart failure(NYHA functional class III or IV). In group 2, 13 patients had LVEF more than 40% and NYHA functional class I or II. Left ventricular volumes and ejection fraction were determined from the echocardiogram obtained in short axis view. As a measure of left vertricular afterload, meridional end-systolic wall stress was calculated. This method is based on the determination of end-systolic left ventricular dimension, wall thickness and peak systolic pressure. RESULTS: 1) End-systolic meridional wall stress was significantly elevated in the patient with aortic stenosis & severe congestive heart failure(group 1) compared with the patient with aortic stenosis and mild congestive heart failure(group 2)(320.09+/-72.09 vs 177.52+/-76.43 dyne x 10(3)/cm2, p<0.005). With group 1 and group 2, there was a significant inverse linear relationship between LVEF and end systolic meridional wall stress(r=-0.907, p<0.001). 2) There was significantly more decreased ratio of end-systolic meridional wall stress to end-systolic volume index(ESWS/LVESVI) of group 1 than that of group 2(5.64+/-2.65 vs 15.30+/-7.77 dyne x 10(3)cm2/ml/m2, p<0.05). And there was a significant linear relationship between LVEF and end-systolic meridional wall stress to end-systolic volume index(ESWS/LVESVI)(r=0.86, p<0.001). 3) Twenty of 20(100%) survived after surgery : 19 of these 20 showed clinical improvement. There was significant improvement of ejection performance(LVEF, % FS) in group 1 except from 1 patient(LVEF 35.43+/-6.90 VS 47.29+/-3.45%, % FS 18.76+/-4.87 vs 28.20+/-3.40, p<0.05). CONCLUSION: Thus, both altered contractility and increased afterload are operative in depressed left vertricular ejection performance in patients wth aortic stenosis ; which one predominates may have major prognostic importance. We found encouraging results for aortic valve replacement in patient with depressed preoperative left ventricular function. The majorty of patients in this series had left ventricular failure because of excessive afterload predominantly.

Coronary artery fistulas (CAFs) are rare, mostly congenital cardiac anomalies. Most are asymptomatic and do not require treatment, but some can cause angina or exertional dyspnea. Symptomatic or hemodynamically significant fistulae can be treated with transcatheter or surgical methods of closure, with the former being a less invasive alternative while showing similar effectiveness and morbidity. We present a 52-year-old man with a complex coronary artery to pulmonary artery fistula causing angina, successfully treated by transcatheter coil embolization. Even without complete closure, this patient showed improvement of symptoms and objective indices of myocardial ischemia.

The worldwide population of the elderly is steadily increasing, and even more so in Korea, thus causing an increase in the osteoporotic fracture prevalence. Osteoporotic fracture is a serious injury that can decrease quality of life, and can also produce major social problems when it causes mortality. Preventing such fractures from happening in the first place is of utmost importance but once a fracture does occur, it is important to select appropriate treatment modalities to prevent secondary fractures. Recently, with the increase of life expectancy, it has become favorable to perform surgical fixation for significantly displaced osteoporotic fractures and use early rehabilitation programs to return the patient to normal body performance as soon as possible. To do so, it is important to accurately assess the location and the degree of the fractures in order to select appropriate treatment modalities. Furthermore, it is important to prevent secondary fractures from happening once the previous fractures heal.

BACKGROUND/AIMS: Despite the U.S. Food and Drug Adminstration approving a magnetic resonance imaging (MRI)-conditional pacemaker system in 2011, many physicians remain reluctant to perform MRI scanning in patients with cardiac implantable electronic devices. Herein, we aimed to evaluate the real-world safety of MRI in these patients. METHODS: This single-center retrospective study examined the interrogation data and outcomes of patients with pacemakers or implantable cardioverter defibrillators who underwent MRI. MRI interrogation data were collected pre- and post-MRI and after 1 month of follow-up; these included the lead impedance, measured P- and R-wave amplitudes, and capture threshold. We compared these results between the magnetic resonance (MR)-conditional and conventional groups. RESULTS: From September 2013 to December 2015, 35 patients with cardiac implantable electronic devices underwent 43 MRI scans, with a mean follow-up of 5 months. Among these 35 patients, 14 (40%) had MR-conditional devices and 21 (60%) had conventional devices. Seven patients had high voltage devices, which were all the conventional type. There were no adverse events associated with MRI during the follow-up period, and there were no significant differences in the interrogation data changes between the conventional and MR-conditional groups. CONCLUSIONS: This single-center retrospective study found that MRI can be performed safely in patients with pacemakers or implantable cardioverter defibrillators, regardless of the MRI support, as long as appropriate precautions are taken.

Lumbar decompressive surgery is a standard surgery for lumbar spinal stenosis. Many surgical techniques have been introduced, ranging from open surgery to percutaneous procedures. Minimally invasive techniques are preferred because of the less postoperative pain and shorter hospital stay. Uniportal percutaneous endoscopic decompression has technical difficulties due to the narrow field. Biportal percutaneous endoscopic decompression is a satisfactory technique that can compensate for the shortcomings and provide sufficient decompression.

Background: Although electrocardiography and cardiac troponin play important roles in the diagnosis of acute coronary syndrome (ACS), there remain unmet clinical needs. Heart-type fatty acid-binding protein (H-FABP) has been identified as an early diagnostic marker of acute myocardial infarction (AMI). In this study, we examined the diagnostic and prognostic value of H-FABP in patients suspected with ACS. Methods: We conducted an observational single-center cohort study, including 89 adults aged 30 years or older, who presented to the emergency room (ER) within 24 hours after the onset of chest pain and/or dyspnea. We performed laboratory analysis and point-of-care testing (POCT) for cardiac markers, including H-FABP, troponin I, and creatine kinasemyocardial band. We also evaluated the correlation between cardiac markers and left ventricular (LV) dysfunction and extent of coronary artery disease (CAD). Results: In patients presented to ER within 4 hours after symptom onset (n = 49), the diagnostic accuracy of H-FABP for AMI, as quantified by the area under the receiver operating characteristic curve, was higher (0.738; 95% confidence interval [CI], 0.591–0.885) than other cardiac markers. In POCT, the diagnostic accuracy of H-FABP (56%; 95% CI, 45–67) was significantly higher than other cardiac markers. H-FABP was correlated with not extent of CAD but post-AMI LV dysfunction. Conclusion H-FABP is a useful cardiac marker for the early diagnosis of AMI and prediction of myocardia injury. Difference in the circulatory release timeline of cardiac markers could explain its utility in early-stage of myocardial injury.

Background: Denosumab (DEN) and zoledronic acid (ZOL) currently represent the most potent antiresorptive agents for the treatment of osteoporosis. Despite similar effects on bone resorption, these agents have distinct mechanisms of action. The objective of this study was to compare the effect of DEN and ZOL after two-year administration on bone mineral density (BMD), trabecular bone score (TBS), bone turnover markers, and persistence. Methods: A total of 585 postmenopausal women with osteoporosis who did not use osteoporosis medications were retrospectively reviewed. 290 patients were administered 60 mg DEN subcutaneously every 6 months from 2017 to 2018, and 295 patients were treated with 5 mg ZOL intravenously yearly from 2015 to 2017. BMD, TBS, and C-terminal crosslinking telopeptide of type 1 collagen (CTX) measurements were obtained at baseline and two-year after DEN injection or ZOL infusion. Results: After two-year follow-up, 188 patients in the DEN group and 183 patients in the ZOL group were compared. BMD change from baseline at two years was significantly greater in the DEN group compared with the ZOL group (P < 0.001). The changes of TBS in the DEN group were statistically significant compared with baseline (P < 0.001) and the ZOL group (P < 0.001). The DEN group led to significantly greater reduction of CTX compared with ZOL group (P = 0.041). Conclusion In postmenopausal women with osteoporosis, DEN was associated with greater BMD increase at all measured skeletal sites, greater increase of TBS, and greater inhibition of bone remodeling compared with ZOL.
