A 49-year-old woman with anemia who developed headache and seizure after blood transfusion was diagnosed with posterior reversible encephalopathy syndrome (PRES). Magnetic resonance imaging showed typical PRES findings including lesions in bilateral parieto-occipital subcortical white matter and overlying cortex. Only a few cases of PRES after transfusion have been reported and this case is unique in that there was a latent period between infusion and development of PRES. We postulate that rapid change of hemoglobin level may disrupt cerebral autoregulation and result in delayed PRES. We suggest that neurological symptoms after blood transfusion should be appropriately investigated.

OBJECTIVE: Cell therapy has been extensively studied as a gene complementation approach in muscular dystrophy including Duchenne muscular dystrophy (DMD), and adipose tissue has recently been identified as a uniquely abundant and adequately accessible source of pluripotent cells. In the present work, we investigated myogenic potentials of adipose-derived stem cells (ADSCs) depending on culture media and isolation with using surface markers. METHOD: Human ADSCs were obtained by liposuction and cultured in two different media; control and myogenic media. In addition we attempted to isolate ADSCs by utilizing surface markers: CD45 and CD133. The following observations were made to evaluate myogenic differentiation as the expression of myogenic regulatory factors (MyoD, Myf-5 and Myf-6) and desmin by RT-PCR and immunoflurescence study. RESULTS: Conversion of ADSCs to myogenic phenotype was observed by indirect immunoflurescence study of MyoD and Myf-5 in regardless of media type and isolation method. In addition mRNA of MyoD and Myf-5 were positive in both culture media, and there were no differences of MyoD and Myf-5 responses between CD45- and CD45-CD133-ADSCs. However, secondary myogenic regulatory factor (Myf-6) was not expressed constantly, and desmin were negative in all cultural condition. CONCLUSION: Our findings suggest that human ADSCs might have myogenic potentials. However, further studies are needed to express the secondary myogenic regulatory factors and proteins in myoblasts.

Duplications of the gastrointestinal tract are rare congenital malformations that are usually present during the first decade of life. However, a smaller number of cases may remain occult until adulthood. Overall, the colon is the least common site of congenital gastrointestinal duplications. Colonic duplications can present with symptoms of diverticulitis and can be confused with acquired giant cysts or masses. We present a rare case of a duplication cyst of the colon in a female adult. Although the preoperative evaluations, including an abdominal CT scan and colonoscopy, were suggestive of a gastrointestinal tumor of the colon, the final diagnosis was a colonic duplication cyst based on the histopathologic examination of the resected specimen. Even if intestinal duplication cysts are uncommon, they should be considered in the differential diagnosis of intestinal masses.

BACKGROUND/AIMS: Although endoscopic resection is widely used for the treatment of early colorectal cancer, the risk factors for lymph node metastasis are not clear. This study was designed to determine the risk factors for lymph node metastasis in patients with colorectal cancer who are treated by endoscopic resection. METHODS: The medical records of patients with histologically-proven early colorectal cancers who were treated by endoscopic resection between January 2002 and September 2008 were retrospectively reviewed. Information regarding the demographic data of patients and the clinicopathologic characteristics were recorded and analyzed. RESULTS: Twenty-nine patients who underwent subsequent surgical treatment after endoscopic resection for early colorectal cancer were enrolled in this study. Six patients (20.7%) had lymph node metastases on surgical pathologic examination. The predictive factors for lymph node metastasis were tumor morphology (non-polypoid flat tumors [p=0.019]), absence of background adenomas (p=0.033), and deep submucosal invasion > or = 2,000 um (p=0.012). Unexpectedly, the presence of vascular invasion was not associated with lymph node metastasis. CONCLUSIONS: The presence of vascular invasion might not be an absolute indication for additional surgical treatment of early colorectal cancer; however, deep submucosal invasion, accompanied by a gross tumor with a non-polypoid flat morphology, and the absence of background adenomas are potential risk factors for lymph node metastasis.

OBJECTIVE: To investigate the usefulness of bioimpedance measurement for predicting the treatment outcome in breast cancer related lymphedema (BCRL) patients. METHOD: Unilateral BCRL patients who received complex decongestive therapy (CDT) for 2 weeks (5 days per week) were enrolled in this study. We measured the ratio of extracellular fluid (ECF) volume by using bioelectrical impedance spectroscopy (BIS), and single frequency bioimpedance analysis (SFBIA) at a 5 kHz frequency before treatment. Arm circumferences were measured at 10 cm above and below the elbow before and after treatment. We also investigated whether there is correlation between ECF ratio and SFBIA ratio with the change of arm circumference after CDT. RESULTS: A total of 73 patients were enrolled in this study. The higher ECF ratio was significantly correlated with higher reduction of arm circumference at both above and below the elbow after treatment, but the higher SFBIA ratio was correlated only with the higher reduction of arm circumference below the elbow. CONCLUSION: These results show that ECF volume measurements and SFBIA before treatment are useful tools for predicting the outcome of patients with lymphedema. We concluded that ECF volume measure can be used as a screening tool for predicting treatment outcome of BCRL patients.

BACKGROUND/AIMS: Gastric stasis in migraineurs remains controversial. The aim of this study is to investigate gastric emptying (GE) time, and any associations between GE parameters and dyspeptic symptoms among patients with functional dyspepsia (FD) and migraine without any gastrointestinal symptoms during the interictal period. METHODS: We enrolled 27 migraine patients, 32 FD patients and 12 healthy people as controls, and performed GE scintigraphy as gastric function test. Gastrointestinal symptoms were evaluated in the FD and migraine. RESULTS: The age-adjusted mean gastric half-emptying time in FD (125.51 +/- 52.55 minutes) patients was longer than in migraineurs (100.82 +/- 23.94 minutes, P = 0.035) and controls (95.25 +/- 23.29 minutes, P = 0.021). The percentage of gastric retention was higher in FD than in migraine. However, migraineurs did not show an obvious delayed gastric emptying or an increase of gastric retention when compared to the normal controls. The association between each dyspeptic symptom and GE parameters was not significant, but postprandial fullness and early satiety showed a tendency of delayed GE. In migraineurs, GE time did not show significant association with nausea and vomiting during interictal periods. CONCLUSIONS: Delayed GE does not appear to be a mechanism that patients with FD and migraine have in common. Migraineurs without dyspepsia during interictal period had normal GE, and further study for association with FD should be investigated.

BACKGROUND: TNF-alpha is related to the generation of lung fibrosis in patients with UIP. The precise mechanism leading to lung fibrosis by TNF-alpha is unknown. However, the activation of a transcription factor like AP-1(down stream of c-jun N-terminal kinase, JNK) by TNF-alpha may be related to the induction of fibrogenic cytokines like PDGF or IGF-I. Furthermore, JNK was reported to be activated in the radiation-in-duced lung fibrosis model. This study examined JNK activity in patients with UIP. METHODS: The expression of phosphorous JNK(p-JNK), macrophage/moncoyte specific markers, CD68, and cytokeratin was evaluated by immunohistochemical (IHC) staining of lung tissues from patients with UIP and lung cancer. An in vitro kinase assay was performed with alveolar macrophages obtained by a bronchollung cancer. An in vitro kinase assay was performed with alvolar macrophages obrtained by a bronchol avleolar lavage from patients with UIP and healthy persons as the control. RESULTS: The IHC stain showed that p-JNK is expressed in the almost all of the alveolar macrophages and smooth muscle cells in patients with UIP. In case of the normal areas of the lung from patients with lung cancer, the alveolar macrophages showed little p-JNK expression. Interestingly, increased JNK activity was not found in the in vitro kinase assay of the alveolar macrophages obtained from both patients with UIP and healthy persons as the control. Furthermore, 10 ng/ml of TNF-alpha failed to increase the JNK activity of the alveolar macrophages in both patients with UIP and healthy people. CONCLUSION: The JNK was activated constitutionally in patients with UIP. However, the role of JNK in the pathogenesis of lung fibrosis needs to be clarified.

Santorinicele, a focal cystic dilatation of the distal duct of Santorini, has been suggested as a possible cause of the relative stenosis of the accessory papilla, is associated with complete pancreas divisum, which results in acute episodes of pancreatitis or pain. This report describes a case of a santorinicele, which was initially detected by upper gastrointestinal endoscopy as a polypoid mass, in a patient with recurrent abdominal pain. The mass was subsequently proved to be a santorinicele containing a pancreatic duct stone associated with incomplete pancreas divisum on endoscopic retrograde pancreatography. To the best of our knowledge this is believed to be the first description of a santorinicele associated with these characteristic findings.

BACKGROUND: In this randomized, double-blinded study, we evaluated the efficacy of ramosetron and ondansetron for preventing postoperative nausea and vomiting (PONV) after middle ear surgery. METHODS: Seventy patients of either sex, ASA 1-2, scheduled middle ear surgery (mastoidectomy and tympanoplasty) under general anesthesia with sevoflurane and remifentanil were included. Patients were randomly divided into two groups and received IV ramosetron 0.3 mg (group R) or ondansetron 4 mg (group O) before the end of operation (n = 35 each). The incidence and severity of PONV, pain score (VAS), rescue antiemetic, rescue analgesic and side effects were assessed following 6 hr, 24 hr and 48 hr after surgery. RESULTS: The incidence of PONV showed no significant difference between groups at each time points after surgery. There were no difference in the severity of nausea, pain score, rescue antiemetic, analgesic drug usage and side effects between groups. CONCLUSIONS: Prophylactic therapy with ramosetron is as effective and safe as conventional prophylactic therapy with ondansetron for preventing PONV in patients undergoing general anesthesia for middle ear surgery.
