Gastritis cystica profunda is an uncommon benign mass that usually occurs on the gastric side of the site of a gastroenterostomy, but has also been known to develop in which has not been operated on. We report the case of stomach a 51-years-old man with pathologically proven gastritis cystica profunda. This patient had not undergone gastric surgery and CT showed a well-defined, 3 cm sized, cystic mass at the gastric antrum.

PURPOSE: We performed this study to evaluate the usefulness and the limitation of magnetic resonance angiography in imaging portal vein and hepatic vein. MATERIALS AND METHODS: Magnetic resonance portography was performed in five normal subjects and seven patients with hepatomas, two patients with Budd-Chiari syndromes, one patient with liver cirrhosis and one patient with hepatic metastasis from stomach cancer. Magnetic resonance angiography was done with a 1.5-T Scanner. Breath-hold two-dimensional time-of flight images with spoiled gradient echo technique were acquired. Scan parameters were 34/8/40degrees(TR ms/TE ms/flip angle). The portal vein and the hepatic vein were selectively imaged by applying two presaturation bands. These images were then postprocessed by a maximum intensity projection algorithm. MRA findings were compared with ultrasonography in all cases of the hepatic disease, and conventional angiography (SMA portography) in four cases. RESULTS: In normal subjects, the splenic vein, intrahepatic and extrahepatic portions of the portal vein, and the hepatic veins were well visualized. In the patients with hepatic diseases, the varices (4 cases), the splenorenal shunts (2 cases), and the recanalized umbilical vein (1 case) were demonstrated. There were portal vein thrombosis in the cases of hepatomas and hepatic metastasis. In the cases of Budd-Chiari syndrome, the hepatic veins were not visualized and there were inferior vena cava obstructions with multiple collateral vessels. CONCLUSION: Compared with ultrasonography, MRP may be useful in evaluation of varices, splenorenal shunts, and other collaterals, though less accurate than conventional angiography. MRP can be useful as a noninvasive screening alternative in the evaluation of portal vein and hepatic veins.

PURPOSE: To characterize the magnetic resonance (MR) imaging features of cervical tuberculous lymphadenitis. MATERIALS AND METHODS: The cervical MR images of 14 patients with pathologically or clinically proven cervical tuberculous lymphadenitis were retrospectively analyzed. T1- and T2-weighted or proton density images and contrast enhanced MR images were obtained in all patients. RESULTS: Most patient had multiple (n=12), unilateral lesions (n=l0), 8 mm to 45 mm in size, round (n=46) or ovoid (n=46) in shape and all with smooth and well-defined margins mostly at internal jugular chain(N2: 41, N3: 2, N4: 21 ). The signal intensities of the most lymph nodes were isointense or slightly hyperintense on T1 -weighted images, and hyperintense (all) with variable homogeneity on T2-weighted and/or proton density images. After contrast enhancement most showed characteristic thin peripheral rim enhancement (n=71). CONCLUSION: The characteristic MR features of cervical tuberculous lymphadenitis would be multiple, unilateral enlarged lymph nodes which show iso or slightly increased signal intensity on T1 -weighted image, high signal intensity on T2-weighted and/or proton density image and peripheral rim enhancement.

Aspirin has been used for decades for the primary and secondary prevention of cardiovascular disease (CVD). The effect of aspirin in secondary prevention is well-known but is still debatable for primary prevention. Despite the controversy, aspirin is believed to have a beneficial effect in primary prevention and has been widely used. However, whether the doubts concerning the wide use of aspirin are correct has resulted in the publication of data from several large clinical trials recently. There are several clinical guidelines from various international organizations on the use of aspirin for the primary prevention of CVD, and they offer some conflicting recommendations. A reduction in the overall incidence of CVD with the development of modern prevention therapies has weakened the impact of aspirin in primary prevention. Large randomized clinical trials have found decreased or no difference in CVD events but a significant increase in the risk of bleeding. Taking aspirin for the primary prevention of CVD is no longer recommended, especially for patients who have a low to moderate risk. An assessment of the balance between the benefits and risks of aspirin use should be considered.

Nonepisodic angioedema with eosinophilia (NEAE) is a rare disease characterized by nonrecurrent angioedema with eosinophilia and normal serum IgM levels occurring predominantly in an East Asian female population. A 49-year-old male patient visited our clinic due to swelling of both the scrotums and the lower extremities, and fever. He had history of nasal polyp, cephalosporin allergy, and asthma. He was diagnosed as having NEAE and was treated with systemic corticosteroid, then he was symptom-free for more than 8 months. He had been administered omalizumab for 3 months due to uncontrolled asthma prior to the onset of angioedema which had helped taper the oral corticosteroid, and this may be associated with presentation of NEAE. Here, we report a case of NEAE in a male patient which presented with constitutional symptoms such as fever and scrotal edema

Hanging is a common method of suicide that is being reported more frequently in many countries. Several complications including injuries to the cervical spine, neck vessels, and brain can occur after attempted suicide by hanging. There are only a few reports of brain computed tomography and magnetic resonance imaging of hanging victims. The most common abnormality was diffuse cerebral edema. A subarachnoid hemorrhage is an atypical complication by suicidal hanging. We report a case of a female patient who presented to an emergency department with altered mental status after attempting suicide by incomplete hanging. The patient was diagnosed with a non-aneurysmal and non-traumatic subarachnoid hemorrhage. This case shows that spontaneous subarachnoid hemorrhage can develop due to a sudden elevation of intracranial pressure, as occurs with hanging.

In the spring of 2011, a cluster of lung injuries caused by humidifier disinfectant (HD) usage were reported in Korea. Many patients required mechanical ventilation, extracorporeal membrane oxygenation, and even lung transplantation (LTPL). However, the long-term course of HD-associated lung injury remains unclear because the majority of survivors recovered normal lung function. Here we report a 33-year-old woman who underwent LTPL approximately four years after severe HD-associated lung injury. The patient was initially admitted to the intensive care unit and was supported by a high-flow nasal cannula. Although she had been discharged, she was recurrently admitted to our hospital due to progressive lung fibrosis and a persistent decline in lung function. Finally, sequential double LTPL was successfully performed, and the patient's clinical and radiological findings showed significant improvement. Therefore, we conclude that LTPL can be a therapeutic option for patients with chronic inhalation injury.

OBJECTIVE: To evaluate whether mTOR inhibition by rapamycin can enhance the inhibitory effect of sodium butyrate, a histone deacetylase (HDAC) inhibitor on human cervical cancer cell line HeLa. METHODS: Cervical cancer cells (HeLa) were treated with sodium butyrate alone or in combination with rapamycin. Cell viability was analyzed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTS) assay and flow cytometry was performed to ascertain the effects of sodium butyrate and combinations of sodium butyrate with rapamycin. Expression of cell cycle related proteins were evaluated by Western blot analysis. RESULTS: As proven previously rapamycin, the mTOR inhibitor was effective in reducing the cell growth of cervical cancer cell line HeLa. Rapamycin and sodium butyrate induced growth inhibition in a dose dependent manner, with 100 nM/L rapamycin and 10 mM/L sodium butyrate blocked 78% cell growth. FACS analysis data substantiated the competence of rapamycin in inducing G1 arrest of mammalian cells, and this ability was greatly enhanced by the combination of sodium butyrate and rapamycin. The percentage of sub G1 fraction of cells was remarkably increased by the combination of sodium butyrate and rapamycin. Sodium butyrate in combination with rapamycin showed the increased expression of CDK inhibitors p21, p27, and dephosphorylation of Rb whereas the expression levels of cyclin A, cyclin D1 and cyclin B1 were reduced. CONCLUSION: The findings implicate that rapamycin could enhance the anti-cancer effect of sodium butyrate. Further in depth studies and in vitro studies would throw more light on the growth inhibitory mechanism and its potential use as therapeutic drugs of butyric acid and rapamycin.

BACKGROUND: In anesthesia for cesarean section, thiopental sodium is regarded as the standard induction agent. Propofol, 2,6 di-isopropyl phenol, is a relatively new intravenous anesthetic agent and has been used for induction and maintenance of general anesthesia or total intravenous anesthesia. Propofol has properties which suggest that it might be useful alternative to thiopental. METHODS: Forty patients (ASA physical status 1,2) scheduled for cesarean section were randomized to either propofol (n=20) or thiopental group (n=20). In thiopental group anesthesia was induced with thiopental 4-5 mg/kg intravenously and maintained by inhalation of enflurane and nitrous oxide. In propofol group anesthesia was induced with propofol 2 mg/kg intravenously and maintained by continuous infusion of propofol 6-10 mg/kg/hr and inhalation of nitrous oxide. RESULTS: Systolic and mean arterial pressure were increased significantly in both groups at 1 min after intubation, but degree of increase were less in propofol group. There was no significant difference in diastolic pressure in both groups. Heart rate was increased significantly in both groups at afterinduction, but degree of increase were less in propofol group. The Apgar scores of the neonates and blood gas analyses of umbilical vein were not significantly different in both groups. Maternal recovery from anesthesia was quicker in propofol group. CONCLUSIONS: A propofol infusion coupled with nitrous oxide was proved to be clinically satisfactory anesthesia for cesarean section with no adverse effect on both mother and fetus. Conclusively, propofol would be an excellant alternative to thiopental sodium and inhalation anesthetic in general anesthesia for cesarean section.

Although accumulating evidence suggests that microglia-mediated neuroinflammation may be crucial for the initiation and progression of Parkinson's disease (PD), and that the control of neuroinflammation may be a useful strategy for preventing the degeneration of nigrostriatal dopaminergic (DA) projections in the adult brain, it is still unclear what kinds of endogenous biomolecules initiate microglial activation, consequently resulting in neurodegeneration. Recently, we reported that the increase in the levels of prothrombin kringle-2 (pKr-2), which is a domain of prothrombin that is generated by active thrombin, can lead to disruption of the nigrostriatal DA projection. This disruption is mediated by neurotoxic inflammatory events via the induction of microglial Toll-like receptor 4 (TLR4) in vivo , thereby resulting in less neurotoxicity in TLR4-deficient mice. Moreover, inhibition of microglial activation following minocycline treatment, which has anti-inflammatory activity, protects DA neurons from pKr-2-induced neurotoxicity in the substantia nigra (SN) in vivo. We also found that the levels of pKr-2 and microglial TLR4 were significantly increased in the SN of PD patients compared to those of age-matched controls. These observations suggest that there may be a correlation between pKr-2 and microglial TLR4 in the initiation and progression of PD, and that inhibition of pKr-2-induced microglial activation may be protective against the degeneration of the nigrostriatal DA system in vivo . To describe the significance of pKr-2 overexpression, which may have a role in the pathogenesis of PD, we have reviewed the mechanisms of pKr-2-induced microglial activation, which results in neurodegeneration in the SN of the adult brain.
