Background: Osteoporotic vertebral compression fractures (OVCFs) are often associated with delayed myelopathy. Surgical treatment of delayed myelopathy following an OVCF comprises spinal canal decompression and stable fixation of the vertebral column with an acceptable sagittal alignment. However, such surgical methods are not usually feasible because of medical comorbidities and osteoporosis. We devised a novel, simple technique to decompress the spinal canal and reconstruct the middle column by translating the fractured vertebral body anteriorly through a posterior approach and verified the validity of the new technique. Methods: We conducted a single-center, retrospective study. Patients who underwent vertebral body anterior translation (VBaT) between 2014 and 2017 due to delayed myelopathy after OVCFs were included. Through a posterior approach, discs between the fractured vertebra and the adjacent vertebrae were released. The fractured vertebra was translated anteriorly with pedicle screws and rods to realign the middle column. Radiological and functional improvement was analyzed. Results: There were 12 consecutive patients. The mean age was 70.3 ± 9.4 years. There were 8 female and 4 male patients. Follow-up period was 35.9 ± 13.1 months. Nine patients had pedicle screw augmentation with polymethyl methacrylate. The mean number of fusion segments was 3.4 (range, 2–4). There were 3 types of spinal canal invasion. Five patients had vertebral body vacuum clefts with posterior wall fractures. Five patients had vertebral body angulation with endplate protrusion. Two patients had 3 column fractures. In radiological analysis, the regional kyphotic angle was 35.1° ± 9.1° preoperatively and improved to 8.8° ± 6.8° postoperatively and 9.8° ± 6.1° at the final follow-up (p < 0.001). The anterior vertebral body height ratio was 27.6% ± 7.0% preoperatively and improved to 80.5% ± 13.7% postoperatively and 83.7% ± 12.5% at the final follow-up (p < 0.001). The spinal canal invasion ratio was 52.6% ± 9.1% preoperatively and improved to 25.2% ± 10.4% postoperatively (p < 0.001). Neurological deficit was improved in all patients by 1–3 grades according to Nurick’s grading system. Conclusions In delayed myelopathy following an OVCF, although the posterior cortex invades the spinal canal, it is usually already in the union state. Therefore, it can bear compression force as a middle column if realigned to be in line with the adjoining vertebrae. VBaT demonstrated satisfactory reduction of kyphosis and maintenance of stability until the last follow-up.

OBJECTIVE: To investigate the effect of laryngopharyngeal neuromuscular electrical stimulation (NMES) on dysphonia in patients with dysphagia caused by stroke or traumatic brain injury (TBI). METHODS: Eighteen patients participated in this study. The subjects were divided into NMES (n=12) and conventional swallowing training only (CST, n=6) groups. The NMES group received NMES combined with CST for 2 weeks, followed by CST without NMES for the next 2 weeks. The CST group received only CST for 4 weeks. All of the patients were evaluated before and at 2 and 4 weeks into the study. The outcome measurements included perceptual, acoustic and aerodynamic analyses. The correlation between dysphonia and swallowing function was also investigated. RESULTS: There were significant differences in the GRBAS (grade, roughness, breathiness, asthenia and strain scale) total score and sound pressure level (SPL) between the two groups over time. The NMES relative to the CST group showed significant improvements in total GRBAS score and SPL at 2 weeks, though no inter-group differences were evident at 4 weeks. The improvement of the total GRBAS scores at 2 weeks was positively correlated with the improved pharyngeal phase scores on the functional dysphagia scale at 2 weeks. CONCLUSION: The results demonstrate that laryngopharyngeal NMES in post-stroke or TBI patients with dysphonia can have promising effects on phonation. Therefore, laryngopharyngeal NMES may be considered as an additional treatment option for dysphonia accompanied by dysphagia after stroke or TBI.

BACKGROUND/AIMS: Transnasal esophagogastroduodenoscopy (T-EGD) has been reported to be well tolerated and is known to reduce patient discomfort that occurs with conventional EGD (C-EGD) performed via an oral route. We aimed to evaluate factors that influence preferences for T-EGD as a surveillance EGD in a general medical checkup. MATERIALS AND METHODS: A total of 658 subjects (median age, 49 years; 45% men) underwent T-EGD procedures by 8 endoscopists using a 5.2-mm diameter endoscope. All examinees and endoscopists were asked to assess the T-EGD examinations using the post-endoscopy questionnaire. The post-endoscopy questionnaire included a 10-point visual analogue scale, which asked the patient to place a cross on the line according to examinee's or endoscopist's experience of the endoscopy procedure. Zero represented the worst experience and 10 the best experience. RESULTS: T-EGD was feasible in 96.6% of the subjects. Younger age (<35 years) and female sex were significant predictive factors for failure of the procedure. Older age (> or =35 years) or male examines preferred T-EGD as the modality for the next examination. The endoscopist's overall discomfort level was higher in the beginner group than in the expert group. CONCLUSIONS: The T-EGD may be better tolerated than C-EGD and offers a more comfortable surveillance endoscopic procedure to older (> or =35 years), male, or sedated C-EGD-experienced examinees in a general medical checkup. More experience with and education about T-EGD may help to improve the tolerance of the beginner group of endoscopists.

BACKGROUND: Stress-induced cardiomyopathy (SCM) is characterized by apical ballooning on echocardiography, but some of SCM patients show non-apical involvement and their characteristics are not well defined. METHODS: We investigated 56 patients that were diagnosed as SCM and divided them into 2 groups: apical ballooning syndrome (ABS, n = 49, 87.5%) and non-apical ballooning syndrome (N-ABS, n = 7, 12.5%) groups. Patients with N-ABS were significantly younger than those of the ABS group (52 +/- 11 vs. 73 +/- 10 years, p < 0.001). RESULTS: Types of preceding stressors and clinical presentation including chest pain, pulmonary edema, cardiogenic shock and in-hospital mortality were comparable between the two groups. In the N-ABS group, wall motion score index was significantly lower than in the ABS group (1.61 +/- 0.35 vs. 1.93 +/- 0.31, p = 0.016). On electrocardiogram (ECG), T-wave inversion (57.1% vs. 95.8%, p < 0.001) were less frequent in the N-ABS than in the ABS group. Furthermore, maximum QT and corrected QT (QTc) intervals in the N-ABS patients were significantly shorter than the ABS patients (QT, 419.9 +/- 66.1 vs. 487.3 +/- 79.6 ms, p = 0.038; QTc, 479.0 +/- 61.9 vs. 568.0 +/- 50.5 ms, p < 0.001). CONCLUSION: Patients with the N-ABS showed not only atypical echocardiographic findings, but also atypical clinical and ECG manifestations. Integrated consideration is needed to reach a diagnosis of the non-apical subtype of SCM.

Aplastic anemia (AA) is a rare complication of liver transplantation. The causes of AA have not yet been identified, and optimal treatment for AA after liver transplantation has not been firmly established. We experienced two cases of AA accompanied with fulminant hepatitis among 157 pediatric recipients (1.3%) and among 17 recipients of Korean Network of Organ Sharing (KONOS) status 1 (11.8%). The patients were a 16-year-old girl and a 3-year-old boy who had jaundice and lethargy due to non-A, non-B, non-C fulminant hepatitis. The girl underwent split liver transplantation involving the liver of a 24-year-old man, and the boy underwent an emergency living donor liver transplantation with a liver obtained from his 16-year-old cousin. Each transplantation procedure was uneventful. However, both patients were diagnosed with AA caused by thrombocytopenia and neutropenia at 140 and 26 days, respectively, after liver transplantation. The girl recovered completely after undergoing bone marrow transplantation and was followed up for 70 months. However, the boy was conservatively treated because of the development of hyperbilirubinemia and pyrexia. He died of multi-organ failure 74 days after liver transplantation. AA is not a rare complication of pediatric liver transplantation for fulminant hepatic failure. Therefore, AA must be suspected in pediatric cases of cytopenia even after liver transplantation. Our findings indicate bone marrow transplantation is the treatment of choice for AA even in cases where AA develops after liver transplantation.

BACKGROUND AND OBJECTIVES: The development of contrast-induced nephropathy (CIN) is associated with an increased risk of death and late cardiovascular events after percutaneous coronary intervention (PCI). The relationship between CIN and hemoglobin drop has been controversial. The aim of this study was to evaluate the clinical usefulness of periprocedural hemoglobin drop as a nontraditional risk factor for CIN. SUBJECTS AND METHODS: Five-hundred thirty-seven patients who underwent PCI were divided into 2 groups: Group I (486 patients: patients who did not develop CIN) and Group II (51 patients: patients who developed CIN). All patients were administered iodixanol as contrast media during coronary angiography. CIN is defined as a rise in serum creatinine of > or =25% or > or =0.5 mg/dL above the baseline value within 48 hours after contrast administration. RESULTS: Baseline clinical and cardiovascular risk factors were not significantly different between the two groups, except for low abdominal circumference (Group I : Group II=87.9+/-9.0 cm : 81.2+/-15.1 cm, p=0.024), body weight (Group I : Group II=63.5+/-10.6 kg : 59.7+/-9.2 kg, p=0.008), body mass index (BMI) (Group I : Group II=24.4+/-3.4 kg/m2 : 23.4+/-2.8 kg/m2, p=0.032), pre-PCI hemoglobin (Group I : Group II=13.2+/-2.0 g/dL : 12.3+/-2.0 g/dL, p=0.003), and post-PCI hemoglobin (Group I : Group II=12.4+/-1.9 g/dL : 11.5+/-1.8 g/dL, p=0.001). Multiple logistic regression analysis showed that a periprocedural drop in hemoglobin (>1 g/dL) was an independent predictor of CIN, like other known risk factors. CONCLUSION: A periprocedural drop in hemoglobin of more than 1 g/dL is another important independent predictor for CIN, even in patients administered the lowest nephrotoxic contrast agent, iodixanol, during PCI.

The incidence of glomerulonephritis associated with malignancy is not common. Membranous glomerulonephritis associated with carcinomas and minimal change nephrotic syndrome with Hodgkin's disease has been occasionally reported. The pathogenesis of glomerular injury associated with malignancy is not well known. The IgA nephropathy associated with malignancy, though rare, has been reported. IgA nephropathy associated with acute myeloid leukemia, however, is yet to be reported. We hereby report a case of IgA nephropathy associated with acute myeloid leukemia (AML M2).
