ABSTRACT
PURPOSE: To evaluate the risk factors for subsequent vertebral fracture following acute osteoporotic vertebral compression fracture. MATERIALS AND METHODS: This was a multicenter retrospective study. We recruited 135 patients treated for acute osteoporotic compression fracture with available spine image taken at the 1-year follow-up mark in 3 different hospitals. The patients were divided into 2 groups in accordance with the occurrence of subsequent vertebral fracture. Variables including age, sex, bone mineral density, medical comorbidity, acute fracture level, presence of prior vertebral fracture, osteoporosis medication, and treatment method were analyzed and compared between the 2 groups. RESULTS: The new subsequent vertebral fractures were detected in 25 patients (18.5%). There were no significant differences between the 2 groups with respect to age, sex, medical comorbidity, presence of prior vertebral fracture, and acute fracture level, as shown by univariate analysis. However, in the group with subsequent vertebral fracture, more patients were treated by vertebroplasty or kyphoplasty and had a femur neck T-score of ≤-2.5, as well as poor compliance of osteoporosis medication with significant difference (p<0.05). According to the multivariate analysis, subsequent vertebral fractures were significantly influenced by vertebroplasty or kyphoplasty (p=0.003, odds ratio=4.71) and femur neck T-score of ≤-2.5 (p=0.013, odds ratio=3.47). CONCLUSION: Subsequent vertebral fractures were found in 19% at the 1-year mark after the treatment of acute osteoporotic compression fracture. The two risk factors for subsequent vertebral fractures were vertebroplasty or kyphoplasty and femur neck T-score of ≤-2.5.

BACKGROUND AND OBJECTIVES: The speckle tracking method using 2-dimensional (2D) echocardiography is not affected by the tethering of neighboring segments and angulation. Global circumferential strain (GCS) of the left ventricle (LV) has been suggested as a systolic index and correlated with LV contractility. The purpose of this study was to investigate whether acute changes in preload affect global circumferential strain and to evaluate the usefulness of GCS by the speckle tracking method. SUBJECTS AND METHODS: 2D echocardiography was performed in 69 patients with end-stage renal disease before and after hemodialysis to measure the LV end-diastolic volume and LV ejection fraction. 2D images were acquired from the short-axis view of the mid-LV for the evaluation of GCS. RESULTS: Mean LV end-diastolic volume significantly decreased from 91.2+/-33.3 mL to 72.3+/-32.0 mL (p+/-0.05), and LV ejection fraction decreased from 63.6+/-13.1% to 60.0+/-11.2% (p=0.006) after hemodialysis. However, mean GCS showed no significant change after hemodialysis (17.2+/-5.3% vs. 16.6+/-4.7%, p=0.13). GCS was found to be well correlated with LV ejection fraction (r=0.54, p<0.05) and peak systolic mitral annular velocity (r=0.46, p=0.000), but not with LV preload (r=0.06, p=0.622). CONCLUSION: GCS using the speckle tracking method is a useful index for the evaluation of LV systolic function because it is not affected by acute preload change and is correlated with LV ejection fraction and peak systolic mitral annular velocity.

Emphysematous pyelonephritis is an uncommon and potentially life-threatening infectious disease. Although there is still controversy about optimal treatment of emphysematous pyelonephritis, published results indicate that the mortality rate in the patients treated with radical nephrectomy is equivalent to that in patients given more conservative treatment. Emphysematous pyelonephritis with autosomal dominant polycystic kidney disease is extremely rare and its clinical course is not revealed clearly. Hearin, we report an emphysematous pyelonephritis in a 64- year-old female patient with autosomal dominant polycystic kidney disease, successfully treated by antibiotics and percutaneous cyst drainage.

We report an unexplained anemia that persisted for 4 months in a renal transplant patient who was receiving immunosuppression therapy that included prednisolone, tacrolimus, and azathioprine. A bone marrow biopsy demonstrated pure erythroid hypoplasia and occasional giant pronormoblasts with intranuclear inclusions, characteristic of a parvovirus B19 infection. Both the serum and bone marrow cells were positive for a parvovirus B19 DNA polymerase chain reaction. The anemia resolved 6 weeks after the administration of IV immunoglobuln. But, 4 months later, refractory anemia developed and persisted despite treatment with IV immunoglobulin. However, the patient showed rapid improvement after tacrolimus was switched to cyclosporin A. A parvovirus B19 infection should be included in the differential diagnosis of renal transplant recipients who present with an anemia associated with low reticulocytes; and clinicians should be awared that tacrolimus may impair the clearance of a parvovirus B19 infection.

One Hundred and eight patients received operation for acute subdural hematoma were evaluated in prognostic factors. They were admitted to the Neurosurgical Department in S.R.C.H during the 3 years from January, 1986 to December, 1988. The results were as follows ; 1) The patients were consist of 85 male patients and 23 female patients with the sex ratio 3.7 : 1. 2) Evaluated prognostic factors were age and sex, preoperative Glasgow coma scale(GCS), preoperative pathological physical findings, time interval from injury to operation, type of injury, midline shift, location of hematoma, thickness of hematoma, and operative procedure. 3) On the statistical analysis, factors of GCS and midline shift were considerable significant factors. 4) In the overall results of 108 patients, 47 patients(43.5%) had good recovery, 9 patients(8.3%) had moderate disabled state, 2 patients(1.9%) were severe disabled state, 4 patients(3.7%) were vegetative state, and 46 patients(42.6%) died.

The authors have analyzed the factors influencing the outcome of the 168 patients with acute epidural hematoma who had been managed in our hospital for 3 years from July 1986 to June 1989. 1) Sex incidence showed that male patients were 4.8 times more commonly affected than females, and the most commonly affected age group was the 3rd decade. 2) The most common cause of injury was motor vehicle accidents. The patients with unknown cause of injury which probably suggested significant delay in starting the clinical managements had a higher mortality rate. 3) The most common site of hematoma was the FTP convexity(63.6%). The patients with diffuse hematoma in the fronto-temporo-parietal region had a high mortality and deteriorated level of consciousness. 4) Skull fractures were not seen only in 9.5% of the patients with acute epidural hematoma. 5) The main factors associated with the higher mortality rate were rapid development of hematoma, pupillary dilatation, low score in Glasgow Coma Scale on arrival, and more midline shifting on brain CT. 6) The patients with concomitant intracranial lesions had a high mortality rate(25.8%), and the patients with acute epidural hematoma alone had a low rate(2%), and the overall mortality rate of the patients with acute epidural hematoma was 11.3%.

We experienced a rare case of sacral meningeal cyst so called sacral perineurial cyst(Tarlov cyst). A 15 years old girl was admitted to the hospital because of sudden severe low back pain and Lt. sciatica for about one week. We performed delayed myelography and spinal computeized tomographic myelography(C.T.M) for differential diagnosis. Delayed filling of contrast media in the cyst was significant in diagnosis of sacral meningeal cyst type II. Laminectomy of sacrum(S1) was performed for partial excision of cystic wall and plastic suture. Operative finding was typical sacral perineurial cyst(Tarlov cyst) which was recently clssified as sacral meningeal cyst type II. The classification of spinal meningeal cysts in the literature was indistinct and confused. We also agree with Nabors et. al, in current classificcation of spinal meningeal cysts, in which the spinal meningeal cysts, in which the spinal meningeal cysts were divided into 3 groups as extradural spinal Mcs Type I(Diverticulum), Type II(perineurial cyst), intradural spinal Mcs(arachnoid cyst).
