A mediastinal mass was aspirated by fluoroscope-guided fine needle aspiration biopsy in a 47 years old female patient. The first aspiration smears were not diagnostic, because of hemorrhagic background and cell paucity. On the second aspiration, the smears were composed of some clusters of benign epithelial cells in hemorrhagic background. Cells were arranged in mostly solid sheets and tended to form glandular lumina in part. Their nuclei were round and vesicular. Nucleoli were not prominent. These findings were suggestive of benign glandular tissue, which was finally confirmed as mediastinal thyroid gland by open thoracotomy specimen.

Nicotinic acetylcholine receptors, a ligand-gated ion c hannels,mediates many important physiological processes. Chronic nicotine admini stration could desensitize nicotinic receptors. Many factors which modulate dese nsitization have been described, including different subunits, agonist, signal t ransduction and cellular microenivornment. The important physiological functions of desensitized receptors still remain controversial, may be modulate synaptic transmission,synapse plasticity and mediate self-protection.

In spite of technical advances in neuroradiology, neuroanesthesiology, and microneurosurgery, the treatment of giant aneurysms remains problematic. Between 1983 and 1995, the authors encountered 42 consecutive cases of giant aneurysms, and this study focuses on their clinical manifestations, management, and outcome. The patients' ages ranged from 5 to 73 years, with peak incidence in the sixth decade ; the male to female ratio was 12 : 30. The follow-up period was from 2 to 110(mean, 36) months. The most common presenting symptom was a mass effect found in 22 patients(52%), followed by subarachnoid hemorrhage in 16(38%). Thirty patients underwent a surgical or interventional radiological procedure, comprising direct neck clipping(n=13), proximal clipping(n=7), detachable balloon occlusion(n=4), wrapping(n=3), trapping(n=1), and partial clipping with thrombectomy(n=2). The mortality rate was 16.7% and the morbidity rate, 40% ; the most common postoperative complication was distal cerebral infarction. At the last follow-up, 22 patients(73%) were able to perform daily activities without assistance. In this clinical study, the authors reviewed general aspects of the treatment of giant aneurysms. In conclusion, treatment of giant aneurysms should-for best results-be tailored to patients' individual requirements, determined after thorough examination. Despite advanced neurosurgical techniques, morbidity and mortality rates remain high.

PURPOSE: The purpose of this study was to develop and evaluate a tool to measure job stress related to occupational characteristics of infection control nurses. METHODS: The tool was developed through the steps of literature reviews, preparatory questions, and a test of validity and confidence. The participants were 212 infection control nurses from 145 Korean hospitals. Data were analyzed using descriptive statistics, Cronbach's alpha coefficients, item analysis, factor analysis. RESULTS: Through factor analysis, 38 items in four domains and nine factors were derived. The Cronbach's alpha coefficient of the final instrument was .95. CONCLUSION: The results of this study indicate that the measurement tool is reliable and valid to measure the job stress of infection control nurses.
