Metastatic bone tumors can lead to development of pathological fractures which may cause incessant pain. Hypercalcemia and hypercalciuria may develop secondary to skeletal metastasis and recumbency, leading to death from cardiac and renal sequeale. The proper surgical treatments of the metastatic bone tumor offer many advantages in relief of pain, simplifying nursing care, restoring resonable mobility and prevent complications. The authors reviewed 24 cases of metastatic bone tumors which received surgical treatment at Severance Hospital from January 1976 to March 1982. The results were obtained as follows: 1. Twenty four among three hundred patients with metastatic bone tumors were treated surgically. 2. There was no sexual preference and 66.7% were observed in the age of 51 to 70 group. 3. The most common site of operation was the femur. 4. The methods of operation were as follows: Resectionoflesion.....................5 Replacement with prosthesis..........3 Open reduction and internal..........10 Spinal fusion..........................2 Laminectomy............................4 5. All cases had received various types of ancillary treatment: radiation in 8 cases, 131I radioactive isotope in 1 case, chemotherapy in 2 cases, hormone therapy in 1 case, radiation and chemotherapy in 3 cases and conservative pain control in 9 cases. 6. Among the 15 followed cases, nine survived more than 6 months and 3 cases longer than 1 year after surgery. The pain was relieved markedly in twenty-three patients, and ambulated well with brace support.

STUDY DESIGN: This is a retrospective study. OBJECTIVES: We wanted to evaluate the effectiveness and safety of a PEEK cage filled with DBM in patients with a distractive flexion injury of the cervical spine. SUMMARY OF LITERATURE REVIEW: AIF of the cervical spine using an autoiliac bone graft and plate fixation is known to be an effective treatment for traumatic injuries. However, the complications arising from the donor site are troublesome, and so fusion with cage is an alternative treatment. MATERIALS AND METHODS: We analyzed 32 cases (22 males and 10 females) with distractive flexion injury of the cervical spine. They underwent anterior decompression and interbody fusion with a PEEK cage and anterior plate fixation. In 18 patients, the cage was filled with autogenous iliac bone (Group I), and for the other 10 the cages were filled with DBM (Group II). RESULTS: All the cases in Group I and Group II achieved fusion except for one case of nonunion in group II. The anterior and posterior vertebral heights of the fused segments of group II were decreased more than those of group I, resulting a statistical difference (p=0.003). The changes of segmental lordosis (p=0.69) and the neurologic status (p=0.22) showed no statistical difference between the two groups. CONCLUSIONS: AIF using a PEEK cage filled with DBM and plate fixation showed no significant clinical differences compared to the case of iliac bone autografting. However, from a radiologic perspective, the time to achieve union was extensive and a case of nonunion was also observed. Therefore, many considerations are necessary when using DBM as a replacement for iliac bone autografting and further research should be done on this subject.

Spinal cord infarction, especially anterior spinal artery syndrome, is a relatively rare disease. We report a case of spinal cord infarction caused by thoracoabdominal aortic aneurysm with intraluminal thrombus. A 52-year-old man presented with sudden onset paraplegia. At first, he was diagnosed with cervical myelopathy due to a C6-7 herniated intervertebral disc, and had an operation for C6-7 discetomy and anterior interbody fusion. Approximately 1 month after the operation, he was transferred to the department of rehabilitation in our hospital. Thoracoabdominal aortic aneurysm with intraluminal thrombus was found incidentally on an enhanced computed tomography scan, and high signal intensities were detected at the anterior horns of gray matter from the T8 to cauda equina level on T2-weighted magnetic resonance imaging. There was no evidence of aortic rupture, dissection, or complete occlusion of the aorta. We diagnosed his case as a spinal cord infarction caused by thoracoabdominal aortic aneurysm with intraluminal thrombus.

We report a case of a 44-year-old patient with paralysis of the left leg who had a thoracic epidural catheterization after general anesthesia for abdominal surgery. Sensory losses below T10 and motor weakness of the left leg occurred after the surgery. Magnetic resonance image study demonstrated a well-defined intramedullary linear high signal intensity lesion on T2-weighted image and low-signal intensity on T1-weighted image in the spinal cord between T9 and L1 vertebral level, and enhancements of the spinal cord below T8 vertebra and in the cauda equina. Electrodiagnostic examination revealed lumbosacral polyradiculopathy affecting nerve roots below L4 level on left side. We suggest that the intrinsic spinal cord lesion and nerve root lesion can be caused by an epidural catheterization with subsequent local anesthetic injection.

Nine patients, who had ten painful bipartite patellae, were managed with a new operative tech nique in which the vastus lateralis insertion to the painful patellar fragment is detached subpe riosteally while the continuity of the tendon-periosteum complex to the main portion of the patella is preserved. A grossly mobile patellar fragment was removed in 3, fragment that showed minimum mobility was left in situ in 5 and fragment that had significant articular component was fixed with 4.0 mm cancellous screw in one. All of the patients had prompt relief of pain and returned to full sports activity within three months of the operation, 2 of 5 patellas that had not been removed united by bone to the main portion of the patella within 2 years post-operatively. Overall, 10 knees had excellent results at an average of four years post-operatively.

PURPOSE: Granulocyte colony stimulating factor (G-CSF) has been known to increase neutrophil production and have anti-inflammatory properties, but the effect of G-CSF on pulmonary system is in controversy. We investigated whether G-CSF treatment could attenuate hyperoxia-induced lung injury, and whether this protective effect is mediated by the down-modulation of inflammatory responses in a neonatal rat model. MATERIALS AND METHODS: Newborn Sprague-Dawley rats (Orient Co., Seoul, Korea) were subjected to 14 days of hyperoxia (90% oxygen) beginning within 10 h after birth. G-CSF (20 microg/kg) was administered intraperitoneally on the fourth, fifth, and sixth postnatal days. RESULTS: This treatment significantly improved hyperoxia-induced reduction in body weight gain and lung pathology such as increased mean linear intercept, mean alveolar volume, terminal deoxynucleotidyl transferase-mediated deoxyuridine triphosphate nick end labeling positive cells. Hyperoxia-induced activation of nicotinamide adenine dinucleotide phosphate oxidase, which is responsible for superoxide anion production, as evidenced by upregulation and membrane translocation of p67phox was significantly attenuated after G-CSF treatment, as were inflammatory responses such as increased myeloperoxidase activity and mRNA expression of transforming growth factor-beta. However, the attenuation of other proinflammatory cytokines such as tumor necrosis factor-alpha and interleukin-6 was not significant. CONCLUSION: In sum, G-CSF treatment significantly attenuated hyperoxia-induced lung injury by down-modulating the inflammatory responses in neonatal rats.

BACKGROUND:
Studies on the relationship between thyroid function and anemia in the euthyroid range are scarce. We aimed to evaluate the association between anemia and serum free thyroxine (fT4) and thyrotropin (TSH) in euthyroid adults.
METHODS:
Data on 5,352 participants aged ≥19 years were obtained from the Korea National Health and Nutrition Examination Survey VI (2013 to 2015). Anemia was defined as hemoglobin (Hb) <13 and <12 g/dL for men and women, respectively.
RESULTS:
Overall, 6.1% of participants had anemia, and more women (9.9%) had anemia than men (2.8%, P<0.001). In multivariate analysis, serum fT4 levels, but not TSH, were positively associated with serum Hb levels in both sexes (P<0.001, each). Serum Hb levels linearly reduced across decreasing serum fT4 quartile groups in both sexes (P<0.001, each). After adjusting for potential confounding factors, participants with low-normal fT4 had 4.4 (P=0.003) and 2.8 times (P<0.001) higher risk for anemia than those with high-normal fT4 among men and women, respectively. When participants were divided into two groups at 50 years of age, in younger participants, men and women with the first quartile were at higher risk of anemia than men with the second quartile (odds ratio [OR], 3.3; P=0.029) and women with the forth quartile (OR, 3.2; P<0.001), respectively. This association was not observed in older participants.
CONCLUSION
These results suggest that a low-normal level of serum fT4 was associated with a lower serum Hb level and a higher risk of anemia in euthyroid adults, especially in younger participants.

Purpose:
To identify US findings suggestive of malignancy in thyroid nodules with follicular lesions of undetermined significance (FLUS) or follicular neoplasm (FN) on fine-needle aspiration cytology (FNAC) and evaluate the diagnostic performance.
Materials and Methods:
Seventy FLUS (n = 57) or FN (n = 13) nodules on FNAC that underwent surgical excision between February 2018 and November 2020 were selected. US findings were retrospectively reviewed. Orientation, margin, echogenicity, calcification, additional findings of the rim, echogenicity, heterogeneity of the solid portion, and the ratio of anterior posterior diameter to lateral diameter (criteria) were assessed. The diagnostic performances of US findings, criteria, and the Korean Society of Thyroid Radiology Thyroid Imaging Reporting and Data System (K-TIRADS) were evaluated using logistic regression analysis.
Results:
Microcalcification, homogeneous solid echotexture, and thickened rims were suggestive of malignancy. Our criteria showed a highest area under the ROC curve (AUC) value of 0.771, sensitivity of 97.14%, accuracy of 77.14%, positive predictive value of 93.33%, negative predictive value of 95.24%, and specificity of 97.14%. The criteria showed a significantly higher AUC value than K-TIRADS.
Conclusion
US findings of homogenous solid portions, thick rims, and microcalcifications suggested malignancy in nodules with FLUS or FN on FNAC. These additional US findings could improve the diagnostic performance of K-TIRADS.
