Aberrant left-sided pulmonary artery(pulmonary artery sling) is an uncommon anomaly, which may cause significant respiratory abnormality. We report a case of pulmonary artery sling which is combined with persistent left superior vena cava and dextrocardia. This case was identified by esophagogram and CT and confirmed by MRI and angiography. We consider that MRI is a valuable new method for the diagnosis of aberrant left-sided pulmonary artery.

Emergency cerclage commonly known as that performed in the setting of advanced cervical dilatation with bulging membranes and associated with significantly increased failure rates. We experienced a successful emergency cerclage for advanced incompetent internal os of cervix ( IIOC ). Pregnancy was prolonged and we delivered viable fetus. Hereby we report this case with the brief review of literature.

To evaluate the typical appearance and the influence in the image interpretation of the metallic artifact which is known as one of the patient-related field artifacts, we analysed the magnetic resonance (MR) images of 40 patients (the total number of metallic materials were 45) acquired at MR 1.5T unit. All patients were screened for the presence of metal. The metallic implants were surgical wires and clips, orthopedic devices, and the other miscellaneous materials. The artifacts produced by metallic objects can be seen on MRI as the focal loss of signal and/or the local distortion of the image. Regardless of their ferromagnetic properties, metallic implants created regional artifacts in their images. Ferromagnetic materials, such as a lead fragment, showed severe artifacts and nonferromagnetic metals showed mild to moderate artifacts. The conspicuity of artifact was related tot he composition, mass, shape, orientation, and the location of the metallic objects in the body. Under high magnetic field strength, there were no significant differences between the various pulse sequences. Artifacts are particularly prominent on gradient-echo images. Our findings indicate that MR imaging of patients with standard nonferromagnetic metallic materials can be successfully performed and usefully interpretated.

PURPOSE: The purpose of this study was to identify the predictors of clinical competence in new graduate nurses. METHODS: The subjects of this study were 238 nurses at 13 general hospitals who have had less than 12 months of nursing experience. The data were collected by structured questionnaire from August 5 to August 31 of 2009 and analyzed by the SPSS Win 12.0 program. RESULTS: The total mean score for clinical competence was 181.05+/-15.17, critical thinking disposition was 94.65+/-8.12, and practice environment was 41.00+/-5.55. There were significant differences of clinical competence according to the GPA (t=-3.58, p<.001), the number of beds in the hospital (t=-3.22, p=.001), instruction by preceptor (t=-2.32, p=.021), and previous experience of clinical practice in the hospital (t=-2.21, p=.028). Additionally, critical thinking disposition and practice environment were positively correlated to clinical competence (r=.50, p<.001; r=.20, p=.002). In multivariate approach, predictors included in this study explained 43% of variance in clinical competence. Significant predictors of clinical competence were critical thinking disposition (beta=.50, p<.001), practice environment (beta=.14, p=.012), and working duration (beta=.13, p=.018). CONCLUSIONS: Based on these findings, it is needed that providing supportive practice environment and developing curriculum for enhancing the critical thinking disposition to improve the clinical competence in new graduate nurses.

Vitamin D deficiency cause rickets, metabolic disorder of growing bone resulting in bony deformities. Rickets is characterized by formation of collagen and osteoid with defective mineralization. We had experienced ??severe case of Vitamin D deficiency Rickets. He was a boy of 23month at age, fed with gruel only for 6month. Physical, biochemical and radiological finding & therapeutic procedure were presented, Literatre review was made briefly.

Magnetic Resonance image(MRI) is used as the diagnostic modality for evaluation of suspected intramedullary tumors and differential diagnosis of these tumors at the spinal cord. We experienced intramedullary astrocytoma of cerviced cord with large syrinx and multiple peritumoral cysts consisted of subacute and chronic hemorrhage at the margin and within the syrinx and cysts on MRI.
