PURPOSE: This study evaluated the treatment effectiveness and proper radiation dose of helical tomotherapy (HT) in spine oligometastases from gastrointestinal cancers. MATERIALS AND METHODS: From 2006 to 2010, 20 gastrointestinal cancer patients were treated with HT for spine oligometastases (31 spine lesions). The gross tumor volume (GTV) was the tumor evident from magnetic resonance imaging images fused with simulation computed tomography images. Clinical target volume (CTV) encompassed involved vertebral bodies or dorsal elements. We assumed that the planning target volume was equal to the CTV. We assessed local control rate after HT for 31 spine metastases. Pain response was scored by using a numeric pain intensity scale (NPIS, from 0 to 10). RESULTS: Spine metastatic lesions were treated with median dose of 40 Gy (range, 24 to 51 Gy) and median 5 Gy per fraction (range, 2.5 to 8 Gy) to GTV with median 8 fractions (range, 3 to 20 fraction). Median biologically equivalent dose (BED, alpha/beta = 10 Gy) was 52 Gy10 (range, 37.5 to 76.8 Gy10) to GTV. Six month local control rate for spine metastasis was 90.3%. Overall infield failure rate was 15% and outfield failure rate was 75%. Most patients showed pain relief after HT (93.8%). Median local recurrence free survival was 3 months. BED over 57 Gy10 and oligometastases were identified as prognostic factors associated with improved local progression free survival (p = 0.012, p = 0.041). CONCLUSION: HT was capable of delivering higher BED to metastatic lesions in close proximity of the spinal cord. Spine metastases from gastrointestinal tumors were sensitive to high dose radiation, and BED (alpha/beta = 10 Gy) higher than 57 Gy10 could improve local control.

BACKGROUND: Mild cognitive impairment (MCI) represents a transitional state between the cognitive changes of normal aging and very early dementia. Recently, the published MCI classification in `The Current Concepts in MCI Conference' suggested subtypes of MCI (amnestic, single nonmemory domain, multiple domains slightly impared) based on recognized heterogeneity. The purpose of this study was to ascertain the existence of subtypes of MCI and investigate their relative prevalence and clinical characteristics. METHODS: We recruited the MCI patients according to the consensus criteria of MCI. We classified them into 3 subtypes of MCI by our working criteria based on the definitions of MCI subtypes and then calculated their respective prevalence. We described their various clinical variables including demographic features, symptoms on the first visit, neuroimaging findings, and the genotype of apolipoprotein E. RESULTS: Sixty patients (36 females and 24 males) were enrolled as MCI and analyzed. The prevalence of each subtype (amnestic, single nonmemory domain, multiple domains slightly impared) were 13 (21.67%), 24 (40.0%), and 23 (38.33%) respectively, suggesting the most prevalent type was the single nonmemory domain type. MCI cases with subcortical vascular features were 18 (11 single nonmemory domain and 7 multiple domains slightly impaired). The ApoE epsilon4 carriers were about 50% of tested patients. CONCLUSIONS: We ascertained the existence of MCI subtypes and investigated their prevalence and various clinical features. In evaluation of MCI patients, we should keep the notion of heterogeneity and subclassification in mind.

We describe a case of anterograde and retrograde amnesia resulting from probable herpes simplex encephalitis. In retrograde amnesia, dissociations not only between episodic and semantic memories, but also between semantic memories for personal and public things were observed. We postulated, using FDG-PET, that the former was caused by mesial temporal lesions, based on `multiple trace theory', and the latter, by bilateral lateral temporal lesions, which were probably related to the retrieval of semantic memory, especially for public things.

A gastric intramural hematoma is very rare and commonly associated with trauma, anticoagulation therapy, coagulopathy, pancreatic disease, aneurysm and peptic ulcer disease. This is a case of gastric intramural hematoma which occurred in a patient taking aspirin after hypertonic saline-epinephrine injection for bleeding from a biopsy site. We describe a case of gastric intramural hematoma that was successfully managed with conservative therapy.

BACKGROUND: Corticobasal degeneration (CBD) is a rare neurodegenerative disorder involving the cortical and subcortical areas enabling it to cause abnormalities of both cognition and movement. In some reports, CBD has been known to develop variable degrees of intellectual, memory and language impairment. However, detailed neuropsychological assessments of CBD up to now have been few. We conducted a detailed neuropsychological investigation and FDG-PET to delineate the pattern of neuropsychological dysfunction of CBD and to correlate neuropsychological dysfunction with FDG-PET findings. METHODS: All 6 patients (5; right handedness, 1; left handedness) were diagnosed with CBD using clinical criteria. All the patients underwent detailed neuropsychological and brain FDG-PET tests. RESULTS: Neuropsychological tests showed multiple cognitive dysfunctions with moderate memory impairment. FDG-PET scans showed asymmetric decreased metabolism in bilateral fronoto-temporo-parietal cortical and subcortical areas. The extent of asymmetricity was greater on the subcortical than cortical areas. Unlike previous reports, the medial temporal and fronto-parietal metabolisms were similarly depressed. CONCLUSIONS: All CBD patients displayed prominent deficits on mostly cognitive domains. FDG-PET may explain the relation between cognitive dysfunctions and cortical hypometabolism and help differentiate CBD with other dementing disorders.

Renal artery stenosis (RAS) is defined as a narrowing of main renal artery or its major branches over 50%, and can be the cause of pulmonary edema, renal failure, malignant hypertension and cerebrovascular diseases. The renin-angiotensin-aldosterone system works as a key role. In this paper, we report a case of a 53 year-old patient with left middle cerebellar peduncle infarction, who showed malignant hypertension and RAS. The RAS was diagnosed by renal artery computed tomography angiography and treated with renal artery angioplasty, stenting and antihypertensive medication. In a young patient with ischemic stroke who has refractory hypertension against antihypertensive medications, RAS should be suspected and evaluated.

PURPOSE: The cardiopulmonary exercise test (CPET) is an important clinical tool for evaluating exercise capacity and is frequently used to evaluate chronic conditions including congenital heart disease. However, data on the normal CPET values for Korean children and adolescents are lacking. The aim of this study was to provide reference data for CPET variables in children and adolescents. METHODS: From August 2006 to April 2009, 76 healthy children and adolescents underwent the CPET performed using the modified Bruce protocol. Here, we performed a medical record review to obtain data regarding patient' demographics, medical history, and clinical status. RESULTS: The peak oxygen uptake (VO2Peak) and metabolic equivalent (METMax) were higher in boys than girls. The respiratory minute volume (VE)/CO2 production (VCO2) slope did not significantly differ between boys and girls. The cardiopulmonary exercise test data did not significantly differ between the boys and girls in younger age group (age, 10 to 14 years). However, in older age group (age, 15 to 19 years), the boys had higher VO2Peak and METMax values and lower VE/VCO2 values than the girls. CONCLUSION: This study provides reference data for CPET variables in case of children and adolescents and will make it easier to use the CPET for clinical decision-making.
