A Case of Successful Endoscopic Submucosal Dissection of Gastric Adenoma in a Patient with Congenital Factor VII Deficiency

Congenital factor VII deficiency is a rare hemorrhagic disorder, and invasive procedures are likely to cause excessive bleeding in these patients. Endoscopic submucosal dissection (ESD) has been accepted as a curative treatment modality for gastric adenoma, early gastric cancer (EGC) and any other mucosal and submucosal tumors. The most important complications of ESD are bleeding and perforation. The use of antiplatelet agents or coagulopathies are risk factors for these complications. There are only few reports of successful ESD with coagulation disorders. We report a case of a 70-year-old female patient who was diagnosed with a gastric adenoma and factor VII deficiency. The patient was successfully treated with ESD. Before ESD, recombinant Coagulation factor VIIa was injected, and the procedure was performed successfully without any complications. In conclusion, ESD can be performed successfully in patients with factor VII deficiency, when recombinant human factor VIIa is administered properly.

A Case of Aplastic Anemia Associated with Systemic Lupus Erythematosus: Successful Treatement with Cyclosporine / 대한류마티스학회지

Systemic lupus erythematosus(SLE) is autoimmune disease in which involves systemic organs. Hematological manifestations are common in patients with SLE but aplastic anemia is very rare and, although various immunosuppressants have been tried, there is no established treatment in aplastic anemia associated with SLE. Furthermore, disease course and prognosis may be different from other aplastic anemia. A 42-year-old woman presented with fever, chilling, myalgia, general weakness, pancytopenia. Her bone marrow aspirate and biopsy revealed almost acellular bone marrow with rare foci of hematopoietic elements and she was diagnosed with SLE simultaneously. High-dose methyprednisolone, prednisolone and cyclophosphamide therapies had been unsuccessful in controlling pancytopenia. Cyclosproine was started and the aplastic anemia was responded. Now she was free of transfusion with more than 10 g/dL of hemoglobin.

Osteoinduction using by Human BMP-2-physio- functional Bioactive Ceramics / 대한정형외과학회잡지

PURPOSE: To assess the properties and the osteogenic potency of the calcium phosphate-recombinant human morphogenetic protein-2 (CaP-rhBMP-2 composite) on glass-ceramics. MATERIALS AND METHODS: Bioactive glass-ceramics,as a scaffold, and a calcium phosphate (CaP) solution (pH7.4) were prepared. Recombinant human bone morphogenetic protein-2 (rhBMP-2) was purified from CHO-K1 cells by transfecting the cells with BMP-2 cDNA. The glass-ceramics were soaked for 3 days at room temperature in saline, a CaP only solution, and a CaP solution containing rhBMP-2. Scanning electron microscopy (SEM), Fourier transform infrared reflection spectroscopy (FT-IR), thin film X-ray diffraction (TF-XRD) and immunofluorescent staining (IF) of the anti-human BMP-2 to composite-coated scaffold were performed to verify the characterization of the scaffold surface. In addition, RT-PCR of osteogenic marker gene and SEM photography were performed after adhering the mouse preosteoblast MC3T3-E1 cells in order to assess the osteoinductivity. RESULTS: CaP-rhBMP-2 composite was coated on the surface of glass-ceramics, as confirmed by SEM, FT-IR, TF-XRD spectrum, and IF. The CaP-rhBMP-2 composite on the glass-ceramic showed a globular shape covered with fine spikes while the CaP on the glass-ceramic showed a fine spike structure on the flat glass surface. The expression of collagen type I and alkaline phosphatase mRNAs had increased 4 hours after cell seeding. In addition, the level of osteocalcin mRNA expression had increased significantly by 3 days in the CaP-rhBMP-2 composite compared with the control and CaP group. The SEM photographs showed more active filopodia formation in the CaP-rhBMP-2 composite than the other groups. There was extensive newly synthesized extracellular matrix around the osteoblasts and CaP-rhBMP-2 composite nodule. CONCLUSION: The application of CaP-rhBMP-2 composite-surface coating technique on bioactive glass-ceramic is a powerful tool for osteoinduction.

An Association between Brain MRI and Neurologic Findings in Welders Exposed to Manganese Fume / 대한산업의학회지

This study was carried out to investigate the relationship between brain magnetic resonance imaging (MRI) and neurological findings in welders exposed to manganese fume. Thirty five welders from a bus manufacturing factory who were occupationally exposed to low dose manganese fume were examined. We collected the information on the demo graphic factors and welding careers. Laboratory investigations included blood and urine manganese concentration and blood chemistry. Brain MRI was checked, and high signal intensity of the globus pallidus was graded from 0 to 3 compared to the white matter of the frontal lobe. Neurologic examination wart carried out. The results were as follows ; 1. The mean age of workers was 48.3+/-5.7 years, mean duration of welding was 21.4 +/-5.6 Years. 2. On brain MRI, high signal intensity in the globes pallidus was observed in 27 workers (77.1%) Among them, 18 cases (66.7%) showed remarkably high signal intensity (grade 2) Mean concentration of blood manganese was higher in those with high signal intensity and correlated to the grade of high signal intensity (p=0.02) 3. On neurologic examination, no workers showed the finding of typical parkinsonism. But 11 workers (31.4%) showed subtle neurological abnormalities such as gait without associated arm movement, postural instability, intention tremor, and so on. Blood manganese concentration of neurologically abnormal group was 2.4+/-0.7 microgram/dL, which was significantly higher, compared to 1.8+/-0.7 microgram/dL of neurologically normal group (p=0.03). 4. Among 27 workers who showed high signal intensity on brain MRI, 10 workers (37%) were neurologically abnormal. Higher grade of signal intensity on globus pallidus showed higher rate of neurologic abnormality (p<0.05) Especially postural instability and gait without associated arm movement were prominent findings. These bindings suggest that high signal intensity on brain MRI might be associated with a prodromal sign of manganese intoxication. Careful neurologic examination should be tool lowed up on welders showing high signal intensity in the golbus pallidus of brain MRI.

A case of chemical meningitis after myelography

Meningeal irritation signs sometimes develop after myelography due to bacterial infection by contamination during the procedure or chemical irritiation by contrast media itself. CSF profiles of chemical meningitis often mimick those of bacterial meningitis, sometimes causing difficulty in differentiation, but in that case clinical course soon reverse in short time without any complication. Postmyelography chemical meningitis by metrizamide (AmipaqueR) has been well described but iohexol (OmnipaqueR) has rarely been reported to cause chemical meningitis. We experienced a patient of chemical meningitis by iohexol and here descibe the case.

The Effect of Diabetes and Hypertension to the Role of Lp(a) as a Risk Factor of the Ischemic Cerebrovascular Disease

BACKGROUND AND OBJECTIVES: It had been well known that Lipoprotein(a) had proatherogenic and thrombogenic action because of structural similarity with plasminogen. However the role of Lipoprotein (a) (Lp(a)) in the development of ischemic cerebrovascular disease had not sufficiently clarified. The aim of this study was to evaluate the effect of diabetes mellitus (DM) and hypertension (HBP) to the role of Lp(a) as a risk factor of ischemic cerebrovascular disease. METHOD: For comparing Lp(a) and the lipid profile of ischemic stroke group (5, N=232) with those of control group (C, N=158), we divided each group into four subgroups according to the existance of DM and HBP: stroke patients and control subjects with DM only(DMS, N=27; DMC, N=44), those with HBP only(HBPS, N=94; HBPC, N=44), those with both of DM and HBP (DMHBPS, N=46; DMHBPC, N=29), and those with none of DM and HBP(NS, N=65; NC, N=41). We evaluated Lp(a) and the lipid profile measured less than 72 hour after onset of stroke and 3 month later in 33 ischemic stroke patients. Also we divided the stroke group into two subgroups according to the type (large artery thrombotic vs small artery perforating) and the age of onset (below 50 year-old vs above 50 year-old), and compared Lp(a) and the lipld profile in each subgroups. RESULT: 1. In control group, the Lp(a) in DMC was significantly higher t that in NC. 2. The Lp(a) compared between HBPC & HBPS and between & NS were statistically significant. 3. The Lp(a) in DMS revealed no significant difference compared with that in DMC. 4, The type of ischemic stroke did not give specific Lp(a) level. 5. The Lp(a) in the young age onset revealed no significant difference compared with that in the old age onset. CONCLUSION: The Lp(a) is likely to contribute to the ischemic stroke at independent risk factor, However it is seemed that the role of Lp(a) as a risk factor of the ischemic stroke is evaluated after being subdivided according existence of DM.

A Case of Gelastic Seizure and Hypothalamic Hamartoma

Gelastic Seizure(Ictal laughter) is frequently associated with hypothalamic hamartoma that is congenital tumor composed of heterotrophic and hyperplastic tissue located in the hypothalamus near the interpeduncular cistern, tuber cinereum, and mamillary body. The seizure usually begins in infancy or childhood and may be accompanied with precocious puberty and cognitive decline. A 14 year-old boy visited to our hospital because of paroxysmal frequent involuntary laughing regardless of emotional change. Brain MRI showed nonenhancing hypothalamic mass that had isointensity with gray matter on T1W1 and hyperintensity on T2Wl. So it was suspected that he had a gelastic seizure accompanied with hypothalamic hamartoma.
