We reviewed 217 patients (270 cases) of thoracic and lumbar fractures and fracture-dislocations, who were treated at Hanyang University Hospital from January, 1977 to December, 1985. We classified spinal injuries according to three column theory and then analyzed the cause of injury, sex-age distribution, treatment and neurological injuries. The results were as follows: 1. The cases were classified into 4 different categories according to the three column theory; compression fractures (191 cases, 70.7%), burst fractures (54 cases, 20.0%), fracture-dislocations(22 cases, 8.2%), and seat belt type injuries (3 cases, 1.1%). And each of these 4 different categories was then subdivided into subtypes. 2. The most common cause of injury was fall from a height (45.2 %). 3. The neurological injuries were occurred in 21 patients (9.7%). The 16 patients with neural deficit in fracture-dislocation, 15 patients were flexion rotation type. The 5 patients with neural deficit in burst fracture, all were incomplete neural deficits. 4. The greatest advantage of Luque instrumentation was an early rehabilitation without external surport.

The majority of non-small cell lung cancer patients present with locally advanced disease that may not be resectable. A single modality treatment such as thoracic radiotherapy often results in an inferior outcome when compared to combined modality treatment. Various combinations of radiotherapy, chemotherapy, and surgery have been tested in patients with locally advanced non-small-celllung cancer with promising results. The favorable results of the combined modality treatment are accompanied by a corresponding increase in treatment related morbidity. In this article, the results of the application of combined modality treatments in the management of locally advanced non-small cell lung cancer are reviewed.

BACKGROUND: Patients with Alzheimer's disease (AD) at an early stage present with memory decline and impairments of language and visuospatial functions. However, some AD patients occasionally show frontal lobe dysfunctions in the early stage those are known to emerge only at the advanced stage. This subtype of AD is called a frontal variant of AD (frontal AD). We report neuropsychological and FDG-PET findings of three cases of frontal AD. METHODS: Three patients met the diagnostic criteria of probable AD proposed by the NINCDS-ADRDA. However, they unusually showed clinical symptoms associated with frontal lobe dysfunctions even if they were relatively in the early stage of dementia. All the patients underwent neuropsychological tests and brain FDG-PET scans. Distribution of glucose hypometabolism was analyzed using statistical parametric mappings (SPM). RESULTS: Results of neuropsychological tests were consistent with findings of AD except that frontal lobe dysfunctions were prominent. FDG-PET scans and SPM analysis of these images showed hypometabolism in the frontal as well as temporo-parietal regions. Unlike the hypometabolism pattern found in frontotemporal dementia, frontal hypometabolism in our patients was not as severe as parietal hypometablism and hypometabolic regions within the temporal lobe were in the middle or posterior part of the middle and inferior temporal gyri rather than in the anterior part. CONCLUSIONS: Detailed neuropsycholgical tests and FDG-PET may help differentiate AD with frontal involvement in its early stage (frontal AD) from frontotemporal dementia. Future studies with FDG-PET in a larger series of frontal AD cases, especially with histologically proven cases, may be needed.
