Diffuse pulmonary meningotheliomatosis (DPM) is an extremely rare condition. We herein report a unique case of DPM in a 54-year-old woman with a previous history of hepatocellular carcinoma. A chest computed tomography showed diffuse bilateral nodular infiltration, suggesting miliary spread of metastatic hepatocellular carcinoma. The patient underwent a video-assisted thoracoscopic surgery for diagnostic purposes. The cut surface of the lung specimen showed multiple dispersed small nodules, consisting of variably sized nests or whorls of bland epithelioid cells often along the walls of alveolar septa or in a perivascular network within the alveolar interstitium. The tumor cells showed immunoreactivity for epithelial membrane antigen, vimentin, and progesterone receptor. DPM should be included in the differential diagnosis of diffuse multiple small nodules or a reticular pattern in the radiologic studies.

We encountered a case of neonatal altoimmune thrombocytopenia(NAIT) due to anti-HLA-B7+B60+B61. Bilateral cephal hematoma and umbilical hematoma were noted at the time of birth. Purpura developed at the third day. Platelet count was 110,000 at birth and decreased to 66,000/micro liter at the day 4. Prothrombin time and partial prothrombin time were within normal limit. The mother's platelet count was 220,000/micro liter and she had no history of abnormal bleeding. Platelet antibody tests empolying mixed passive hemagglutination and immunofluorescence revealed that the mother's serum was reactive against the platelets from the father and the neonate, but was not reactive with her own platelets. Platelets from eight volunteer group 0 donors were tested with the mother's serum; seven were reactive and one was negative. The positive reactions were lost after chloroquine treatment of platelets. Antigen capture ELISA(ACE) and modified antigen capture ELISA employing monoclonal antibodies against platelet glycoproteins In, IIa, IIb, and IIIa were negative. Mother's serum was tested for lymphocytotoxicity against 49 donor ]ymphocytes and the specificity was found to be anti-HLA-B7+B60+B61. At the 9th day, one unit of platelet concentrate from the mother was transfused and the platelet count of the neonate rose up to 340,000/micro liter. The neonate was discharged at the day of sixteenth and the platelet count remained high thereafter.

OBJECTIVE: Although several prior works showed the white matter (WM) integrity changes in amnestic mild cognitive impairment (aMCI) and Alzheimer's disease, it is still unclear the diagnostic accuracy of the WM integrity measurements using diffusion tensor imaging (DTI) in discriminating aMCI from normal controls. The aim of this study is to explore diagnostic validity of whole brain automated probabilistic tractography in discriminating aMCI from normal controls. METHODS: One hundred-two subjects (50 aMCI and 52 normal controls) were included and underwent DTI scans. Whole brain WM tracts were reconstructed with automated probabilistic tractography. Fractional anisotropy (FA) and mean diffusivity (MD) values of the memory related WM tracts were measured and compared between the aMCI and the normal control groups. In addition, the diagnostic validities of these WM tracts were evaluated. RESULTS: Decreased FA and increased MD values of memory related WM tracts were observed in the aMCI group compared with the control group. Among FA and MD value of each tract, the FA value of left cingulum angular bundle showed the highest area under the curve (AUC) of 0.85 with a sensitivity of 88.2%, a specificity of 76.9% in differentiating MCI patients from control subjects. Furthermore, the combination FA values of WM integrity measures of memory related WM tracts showed AUC value of 0.98, a sensitivity of 96%, a specificity of 94.2%. CONCLUSION: Our results with good diagnostic validity of WM integrity measurements suggest DTI might be promising neuroimaging tool for early detection of aMCI and AD patients.

Because additive effects of inhaled corticosteroids and long-acting anticholinergics are unclear, we undertook this study to compare the efficacy of tiotropium alone and tiotropium plus budesonide in patients with chronic obstructive pulmonary disease. The study subjects were randomized to receive either tiotropium 18 microgram once daily with or without budesonide 200 microgram twice daily for 6 weeks. The efficacy variables were changes in trough forced expiratory volume in one second (FEV1), St. George's Respiratory Questionnaire (SGRQ), 6-minute walk distance (6MWD), and use of rescue medication. One hundred patients were randomized and 81 completed the study. The mean age was 64.0 yr, and the mean FEV1 was 39.7% predicted. Compared with tiotropium alone (N=40), the tiotropium/budesonide combination (N=41) was related to an improvement in the SGRQ total score (tiotropium -2.8 units and tiotropium/budesonide -5.6 units, p=0.003). 6MWD was improved by 13.5 m in the tiotropium group and by 22.5 m in the tiotropium/budesonide group (p=0.031). Changes in trough FEV1 and the use of rescue medication were similar between two groups. In conclusion, compared with tiotropium alone, the tiotropium/ budesonide combination was related to an improved health-related quality of life. These data support that low-dose budesonide may enhance the efficacy of tiotropium.

Acute traumatic spondylolisthesis at L5-S1 level is a rare condition, almost exclusively the result of major trauma, frequently associated with transverse process fractures and severe neurologic deficits. Recently, open reduction and internal fixation with posterior stabilization has been the method of treatment most frequently reported. We report a rare case of traumatic L5-S1 pondylolisthesis with a unilateral facet locking with a review of literatures.

8.The Role of EBUS-TBNA in the Diagnosis and Staging of Lung Cancer.
Hanyang Medical Reviews 2014;34(1):20-25
Convex-probe endobronchial ultrasound-guided transbronchial needle aspiration (CP-EBUS-TBNA) has emerged as a new diagnostic modality that allows ultrasound-guided, real-time needle aspiration of mediastinal and hilar lymph nodes. Mediastinoscopy has been the reference standard for neoplastic staging in the mediastinum, but it is invasive and requires general anesthesia. Considering recent prospective studies and clinical guidelines, a needle technique such as EBUS-TBNA and endoscopic ultrasound-guided fine needle aspiration (EUS-FNA) should be performed first for the mediastinal nodal staging of non-small lung cancer. Combining EBUS-TBNA and EUS-FNA will replace more invasive methods such as mediastinoscopy. CP-EBUS-TBNA can also be used for the restaging after neoadjuvant therapy, the diagnosis of recurrent lung cancer and central lung parenchymal lesion which abuts trachea or bronchi. In the era of personalized medicine, good-quality and sufficient tissues need to be obtained for the molecular testing and treatment guidance. EBUS-TBNA has the ability to obtain satisfactory material for the detection of EGFR mutation, KRAS mutation, and EML-ALK fusion gene.

PURPOSE: The ErbB family is associated with cell growth, differentiation, cell survival, apoptosis, cell cycle progression, angiogenesis. In this study, the expressions of ErbB family of colorectal cancer specimen were investigated to determined correlations between the clinicopathologic characteristics and the expression of ErbB family in the curative resection for colorectal cancers, including cancer specific survival. METHODS: Patients who underwent the curative surgery for colorectal cancers from January 1997 to December 2000 at Ansan Medical Center, Korea University College of Medicine were enrolled in this study, and one hundred ninety six of colorectal cancer. The clinical relationship between the expression of ErbB family for colon adenocarcinoma and clinicopathologic characteristic factors including survival were analyzed. RESULTS: There was no clinical relationship of the expression of ErbB family with clinicopatholologic characteristics. However, survival analysis demonstrated that 5 year survival rates (5YSR) of patients with the positive expression of ErbB1 (EGFR) was lower than those of the negative expression of ErbB1 (P<0.05) in colorectal cancer patients. Moreover 5YSR of the positive expression of ErbB1 was lower than that of negative expression of ErbB1 in well differentiation subgroup, node negative subgroup, node positive subgroup, and also stage T3 subgroup (P<0.05). CONCLUSIONS: The positive ErbB1 expression of colorectal cancer was one of poor prognostic factors in patients with colorectal cancer in this study. We need the further study to prove the real relation between target therapy for the positive expression of ErbB1 (EGFR) in colorectal cancer and the improvement of survival rate.

Thymofibrolipoma is an extremely rare tumor in the anterior mediastinum, and represents a histologic variant of the usual thymolipoma. Herein, we report a case of thymofibrolipoma in a 9-year-old girl who had a huge mass with fatty attenuation in the right hemithorax on chest computed tomography. She denied any subjective symptoms except mild fever. The surgically resected tumor was ovoid, soft and well-encapsulated, measuring 9.0 x 7.5 x 7.0 cm. The cut surface was light tan in color with yellowish streaks. Microscopically, two distinct areas were admixed in different proportions. One consisted of normal thymic tissue with subinvoluted features and the other was composed of extensive areas of collagenous tissue interspersed in mature adipose tissue. In a high power view, there were thin strands of remnant thymic epithelial cells, separating the pseudolobules. Thymofibrolipoma should be distinguished from other benign or malignant conditions, occurring in the anterior mediastinum, so that unnecessary treatment can be avoided.
