Abstract
Hypercoagulability disorders are commonly encountered in clinical situations in patients with a variety of cancers. However, several hypercoagulability disorders presenting as first symptoms or signs in cancer patients have rarely been reported. We herein described a case of a woman with adenocarcinoma of the lung presenting with deep vein thrombosis, nonbacterial thrombotic endocarditis, recurrent cerebral embolic infarction, and heart failure.

Abstract
Epithelial growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) have been widely used for non-small-cell lung cancer patients. Its untoward cutaneous effects are largely well known and developed in many patients treated with EGFR TKIs. However trichomegaly of eyelash is rarely reported. Although trichomegaly is not a drug-limiting side effect, it could be troublesome of continuing the treatment because of cosmetic issue or eyeball irritation by long eyelashes. Therefore clinicians are needed to pay attention to this uncommon effect. We herein describe erlotinib induced trichomegaly of eyelashes in a woman with adenocarcinoma of the lung.

Abstract
BACKGROUND/AIMS To determine whether female smokers are more or less susceptible to the detrimental pulmonary-function effects of smoking when compared to male smokers among patients with lung cancer. METHODS Pack-years and pulmonary function indices were compared between 1,594 men and women with lung cancer who were smokers or had a history of smoking. Differences in individual susceptibility to smoking were estimated using a susceptibility index formula. RESULTS Of the patients, 959 (92.8%) men and 74 (7.2%) women were current smokers. Common histological types of lung cancer were squamous cell carcinoma, adenocarcinoma, and small cell carcinoma, among others. Women had a lower number of pack-years, forced expiratory volume in 1 second (FEV(1), liters), forced vital capacity (FVC, liters), and total lung capacity (TLC, liters) compared to those of men (25.0 ± 19.2 vs. 42.9 ± 21.7 for pack-years; 1.4 ± 0.5 vs. 2.0 ± 0.6 for FEV(1); 3.0 ± 0.7 vs. 2.0 ± 0.6 for FVC; 4.5 ± 0.8 vs. 5.7 ± 1.0 for TLC; all p < 0.001). The susceptibility index for women was significantly higher compared to that of men (1.1 ± 4.1 vs. 0.7 ± 1.1; p = 0.001). A significant inverse association was shown between the susceptibility index and TLC and FVC (r = -0.200 for TLC, -0.273 for FVC; all p < 0.001). CONCLUSIONS The results suggest that the detrimental effects of smoking on pulmonary function are greater in women, as compared to those in men, among patients with lung cancer.

Abstract
Purpose To determine whether germ-line variations in BRCA1 affect outcome in non–small-cell lung cancer (NSCLC) patients treated with platinum combination chemotherapy. Patients and Methods We evaluated the associations of four tagging BRCA1 polymorphisms and their haplotypes with treatment outcome in 300 NSCLC patients at stages IIIA (16%), IIIB (31%), and IV (53%). Results The median age was 63 years (range, 28 to 89 years). Histologically, 139 (46.3%) of the patients had squamous cell carcinomas and 137 (45.7%) had adenocarcinomas. Patient median survival time (MST) was 13.0 months. We observed no significant association between any of the tagging polymorphisms [S1613G, IVS13-1893 (A>C), IVS12-1207 (C>T), and IVS12+112 (C>A)] and overall survival. Of the five haplotypes evaluated (AACC, AACA, GCTC, GATC, and AATC), the survival of patients with two copies of the AACC (wild-type) haplotype was significantly shorter than that of patients with zero to one copies (MST, 8.47 v 14.57 months; log-rank P = .0066), even after adjustment for body weight loss, performance status, stage, second-line treatment, and radiation therapy (hazard ratio = 2.097; 95% CI, 1.339 to 3.284). The survival of patients with squamous cell carcinoma and two copies was significantly shorter than that of other patients with squamous cell carcinoma (MST, 6.8 v 15.3 months; log-rank P = 3.6 × 10−5), whereas differences in survival between the two adenocarcinoma groups was not significant (log-rank P = .677). Conclusion These findings suggest that the AACC haplotype of the BRCA1 gene is an important prognostic marker in NSCLC patients treated with platinum combination chemotherapy.

Abstract
OBJECTIVES To investigate whether smoking and the smoking status are predictors of the incident impaired fasting glucose (IFG) or type 2 diabetes in Korean men. METHODS A cohort of 1,717 Korean men without IFG or diabetes, who underwent annual periodic health examinations for 4 years (2002-2006), were retrospectively investigated. IFG and diabetes were defined as a serum fasting glucose concentration of 100-125 mg/dL and more than 126 mg/dL, respectively. Cox's proportional hazards model was used to evaluate the association between smoking and development of IFG or type 2 diabetes. RESULTS A total of 558 cases (32.5%) of incident IFG and 50 cases (2.9%) of diabetes occurred. After controlling for the potential predictors of diabetes, the relative risk for IFG, compared with the never smokers, was 1.02 (95% CI=0.88 to 1.19) for the ever-smokers, 0.96 (95% CI=0.79-1.16) for those who smoked 1-9 cigarettes/d, 1.15 (95% CI=1.01 to 1.30) for those who smoked 10-19 cigarettes/d, and 1.31 (95% CI=1.10 to 1.57) for those who smoked 20 or more cigarettes/d (the P value for the current smokers was only p<0.002). The respective multivariate adjusted relative risks for type 2 diabetes, compared with the never-smokers, were 1.07 (95% CI=0.64 to 1.92), 1.47 (95% CI=0.71 to 3.04), 1.84 (95% CI=0.92-3.04), and 1.87 (95% CI=1.13-3.67), respectively (the P value for the current smokers was only p=0.004). CONCLUSIONS The smoking status and the number of cigarettes smoked daily are associated with an increased risk for developing IFG or type 2 diabetes in Korean men.

Abstract
Evidence as to whether clinician has to give specific treatment in all patients of catamenial hemoptysis is unclear. We considered that the current treatment such as long-term usage of hormonal agent or surgery might be excessive for the catamenial hemoptysis. Therefore, we developed prospective observation study with observation strategy and follow-up for the patients. In sequential four patients of catamenial hemoptysis between December 2000 and November 2001, physical examination, chest X-ray, pelvic ultrasonogram and chest CT scan were taken at both the diagnosis and last follow-up. All patients were only observed without specific treatment within the limit of the possibility and followed for average 58 months. Mean age of patients was 23.5years (range, 22-25years). All patients have a history of undertaking one or two dilatations and curettages before diagnosis. The chest CT scans of all patients presented with ground-glass opacities of peripheral location that were disappeared without any residual lesion at last follow-up. Hemoptysis of two patients was spontaneously disappeared after 6 months. In the other two patients, it was greatly lessened in amount and frequency, then clinically insignificant in one. It was disappeared after subsequent 2 months and then relapsed two times in the late of follow-up of another patient. This study suggests that observation only may be an alternative option in the treatment of catamenial hemoptysis.

Abstract
A few reports for ERCC1 SNPs were conducted in patients treated with cisplatin chemotherapy. The aim of this study is to determine whether the SNPs are a prognostic factor related to the treatment or not and if smoking level of the patients have any relationship to the SNPs' effect on the survival. Peripheral blood lymphocytes of 423 consecutive non-small cell lung cancer patients were examined: 245 of the patients received cisplatin combination chemotherapy and 178 received only conservative care. We examined ERCC1 SNPs (codon 118 C/T and 8092 C/A). Whereas ERCC1 118 SNP had no effect on the survival in patients' given no treatment, an effect of the SNP was observed in the treatment group, especially in stage III. When smoking was considered, the risk effect of the T allele was shown to be significantly associated with the group that had more than 50 pack yr (p=0.03). As for the ERCC1 8092 C/A, no significant effects were observed in the treated group and the non-treatment group. These findings may suggest that the ERCC1 118 SNP is an useful prognostic factor related to cisplatin therapy and the effect of this polymorphism appears to be modified by smoking.

Abstract
Cryptococcus neoformans commonly causes opportunistic infections in immunocompromised patients, especially in patients with AIDS. CD4+ T-lymphocytopenia in AIDS indicates an increased risk of opportunistic infection and a decline in immunological function. Idiopathic CD4 T-lymphocytopenia (ICL) is characterized by depletions in the CD4+ T-cell subsets, without evidence of HIV infection. Immunodeficiency can exist in the absence of laboratory evidence of HIV infection, and T-cell subsets should be evaluated in patients who present with unusual opportunistic infections. We report a case of pulmonary cryptococcosis and lung cancer in a patient with persistently low CD4+ cell counts, without evidence of HIV infection.

Abstract
Acute respiratory distress syndrome (ARDS) caused by adenovirus is a rare event in healthy adults, especially in non- military settings. Although treatment with intravenous ribavirin has been reported, supportive care, including mechanical ventilation, is known to be the main stay in the treatment of ARDS caused by adenovirus, with high-dose steroid treatment having rarely been reported. We report our experience with a 41-year-old, otherwise healthy, woman with ARDS, treated with high-dose steroid and mechanical ventilatory support.

Abstract
RATIONALE AND OBJECTIVES In the noninvasive evaluation of bone quality, bone mineral density (BMD) has been shown to be the single most important predictor of bone strength and osteoporosis-related fracture. Among the methods of measuring BMD, dual x-ray absorptiometry (DXA) has widespread acceptance due to its low radiation, low cost, and high precision. However, DXA measures area BMD instead of true volumetric density; thus, a larger bone will tend to have a high BMD than will a smaller bone. Therefore, the comparison of BMDs of bones of different sizes can be misleading. In this study, the authors tried to compensate for the size effect by normalizing the area BMD with bone size as measured from a standard pelvic radiograph. MATERIALS AND METHODS The overall method for calculation of normalized BMD included conventional area-based BMD from DXA and the extraction of geometric measures from pelvic radiographs. The database for analysis included 34 femoral neck specimens. Regression analysis was performed between the normalized volumetric BMD, measured from femoral neck region, and the mechanical properties obtained from trabecular bone cubes machined from the same region. RESULTS After normalization of the area BMD, the coefficient of determination increased from 0.30 to 0.43 for the Young modulus and from 0.27 to 0.37 for bone compressive strength. CONCLUSION A noninvasive method of normalizing BMD can improve the prediction of bone mechanical properties and has potential in monitoring changes in growing skeletons and in the clinical evaluation of bone quality.

Abstract
A retrospective review of the frontal and lateral knee radiographs of 200 patients with calcium pyrophosphate dihydrate (CPPD) crystal deposition disease was performed. Of these 200 patients, nine patients (four male, five female, mean age 74 years, age range 63-87 years) had radiographic findings simulating osteonecrosis of the knee. One patient also had magnetic resonance imaging of the involved knee. A total of 10 knee radiographs in nine patients showed articular and periarticular calcification diagnostic of CPPD crystal deposition of the knee. In addition, all 10 radiographs showed flattening of one femoral condyle. Four of the 10 cases demonstrated an area of radiolucency in the subchondral bone surrounded by a halo of sclerosis. Eight of the 10 cases had narrowing of the involved joint compartment and osteophytosis. These findings mimic the radiographic signs of spontaneous osteonecrosis of the knee. In conclusion, flattening of the femoral condyles in CPPD crystal deposition disease simulates that of spontaneous osteonecrosis and probably relates to articular cartilage and meniscal damage that subsequently leads to stress fracture of subchondral bone with bone collapse.

Abstract
Tumor immunity is primarily mediated by cells as CD8+ cytotoxic T lymphocytes (CTL) recognize tumor antigen by MHC class I molecules. But most tumors are associated with a decreased expression of MHC class I to escape the antitumor immunity of the host. Our previous data have demonstrated that MPL has an antitumor effect on metastatic lung cancer of B16 melanoma with enhancing cytotoxicity due to increase of IFN-gamma and IL-2, and decrease of IL-4, which indicates the stimulation of type 1 helper T cells (Th1). To determine the effects of MPL, IFN-gamma, TNF-alpha, and IL-1 alpha on MHC class I expression of B16 melanoma cells, we evaluated the expression of MHC class I molecules with treatments of MPL, IFN-gamma, TNF-alpha, and IL-1 alpha by flow cytometry. The supernatant of MPL-treated spleen cells in vitro upregulated the expression of MHC class I molecules of B16 melanoma cells compared to the control supernatant of spleen cells. The MHC class I expression of B16 melanoma cells treated with IFN-gamma, but not TNF-alpha or IL-1 alpha, increased in a time-dependent manner. In conclusion, MPL upregulated MHC class I expression of B16 melanoma cells by activating spleen cells via IFN-gamma. These data suggest that increased IFN-gamma by MPL is responsible for the upregulation of MHC class I expression to augment cytotoxicity. Therefore, we suggest that MPL could play an important role in immunotherapy.

Abstract
PURPOSE To compare neutral, external rotation, and abduction external rotation positions of the glenohumeral joint during magnetic resonance (MR) arthrography in the assessment of the joint capsule, biceps-labral complex, and glenohumeral ligaments. MATERIALS AND METHODS MR imaging with intraarticular administration of gadopentetate dimeglumine was performed in 10 adult cadaveric glenohumeral joints. Fat-suppressed oblique coronal, oblique sagittal, and axial. T1-weighted spin-echo imaging and axial three-dimensional spoiled gradient-recalled imaging were performed with each shoulder in the neutral, external rotation, and abduction external rotation positions. Shoulders were sectioned in the planes that yielded optimal MR images. Anatomic and MR imaging findings were correlated. RESULTS The biceps-labral complex was best visualized on oblique coronal and axial images obtained in external rotation. Oblique axial abduction external rotation imaging best delineated the inferior glenohumeral ligament but did not improve assessment of the superior and middle glenohumeral ligaments in comparison with findings in neutral and external rotation. CONCLUSION Although MR arthrography of the glenohumeral joint clearly delineates the biceps-labral complex and glenohumeral ligaments, external rotation of the shoulder optimizes visualization of the former structures. Abduction external rotation is the best position for evaluation of the inferior glenohumeral ligament and anterior capsular attachment.

Abstract
RATIONALE AND OBJECTIVES The authors assessed the ability of a low-field-strength extremity-only magnet to provide visualization of the triangular fibrocartilage and the scapholunate and lunotriquetral ligaments. METHODS Twelve human wrists were examined with a 0.2 T extremity-only magnet. T1-weighted spin echo, proton density-weighted, and T2-weighted turbo spin echo, short-tau inversion recovery, and three-dimensional gradient recalled echo images were acquired, and sections of the specimens were then made that corresponded to the magnetic resonance images. Masked imaging analyses were correlated with macroscopic and limited histopathologic findings. RESULTS Low-field-strength extremity-only magnet allowed consistent visualization of the triangular fibrocartilage and accurate assessment of a small number of complete tears of the triangular fibrocartilage. The scapholunate ligaments in all cases were identified using a combination of imaging sequences. Consistent visualization of the lunotriquetral ligament with a low-field-strength extremity magnet was difficult. CONCLUSIONS Magnetic resonance imaging with a low-field-strength extremity-only magnet can be used to visualize the triangular fibrocartilage and the scapholunate ligament, but not the lunotriquetral ligament.

Abstract
PURPOSE To assess a low-field-strength extremity-only magnet in the evaluation of patellar cartilage abnormalities. MATERIALS AND METHODS Four regions in each of 10 patellae from cadavers were examined in the transaxial plane with a 0.2-T extremity-only magnet and the following sequences: T1-weighted spin echo, proton density- and T2-weighted turbo spin echo, short inversion time inversion recovery, and two- and three-dimensional gradient echo with and without magnetization transfer contrast subtraction. Lesions depicted with MR imaging and seen in anatomic sections of the patellae were classified according to a modified standardized arthroscopic grading system. MR imaging and pathologic correlation was then analyzed. RESULTS On the basis of macroscopic findings, 14 of 40 cartilage regions were found to be intact, grade 2A lesions were present in eight regions, grade 2B lesions in eight, and grade 3 lesions in 10. For the various MR imaging techniques, sensitivity was 25%-62% for grade 2A lesions, 50%-75% for grade 2B lesions, and 60%-90% for grade 3 lesions. Specificity was 81%-97% for grades 2A and 2B lesions, and 80%-97% for grade 3 lesions. Accuracy was 75%-82% for grade 2A lesions, 75%-92% for grade 2B lesions, and 80%-92% for grade 3 lesions. CONCLUSION High-grade cartilaginous lesions can be evaluated reliably with low-field-strength MR imaging by using a combination of imaging sequences.

Abstract
OBJECTIVE The authors examined the incidence and radiologic characteristics of plexiform neurofibromas in neurofibromatosis-1 (NF-1) to define a cohort at greatest risk for malignant nerve-sheath tumors. BACKGROUND Plexiform neurofibromas are a frequent complication of NF-1. They can impair function, produce disfigurement, and be the site for the development of malignant nerve-sheath tumors. The incidence and natural history of plexiform neurofibromas is unknown. METHODS CT imaging of the chest, abdomen, and pelvis was performed in 91 of 125 consecutive adults (age, > or = 16 years) with NF-1. RESULTS Twenty percent of patients had plexiform neurofibromas of the chest in the paraspinal, mediastinal, or supraclavicular area. Approximately 40% of patients had abnormal abdominal/pelvic scans. The paraspinal, sacral plexus, sciatic notch, and perirectal regions were the most common sites. Most plexiform neurofibromas were asymptomatic. Imaging also revealed a number of tumors, including malignant nerve-sheath tumors, adrenal tumors, carcinoids, and schwannomas. CONCLUSIONS The frequency of plexiform lesions and other tumors in NF-1 indicates that clinicians should monitor young adults carefully; however, imaging characteristics alone cannot reliably distinguish benign from malignant lesions.
