BACKGROUND: During a 1-month period in 2005 , a series of 4 Leclercia adecarboxylata and 8 Pseudomonas aeruginosa bacteremias were reported from patients admitted to the emergency room. METHODS: An outbreak of L. adecarboxylata and P. aeruginosa bacteremia that occurred from February to March 2005 was investigated. The infection control nurse reviewed medical records and observed the procedures of blood cultures at the clinical microbiology laboratory. Specimens were obtained for investigational cultures from alcohol sponge, tray, sink, water of sink, saline cotton, microscope, computer, and telephone. RESULTS: L. adecarboxylata was isolated from 4 patients and P. aeruginosa from 8 patients during a 1-month period. Observation of the culture procedure revealed that saline cotton was used to prevent betadin skin discoloration. The culture of the saline solution yielded a heavy growth of P. aeruginosa, which was not isolated from any other specimens. CONCLUSIONS: This was a pseudoepidemic caused by contaminated saline cotton. The use of the saline cotton was stopped, and during the follow-up period of 3 months, no additional L. adecarboxylata or P. aeruginosa bacteremia were reported.

OBJECTIVE: This study was designed to validate the cell trafficking efficiency of the in vivo bioluminescence image (BLI) study in the setting of transplantation of the luciferase expressing bone marrow-derived mesenchymal stem cells (BMSC), which were delivered at each different time after transient middle cerebral artery occlusion (MCAO) in a mouse model. METHODS: Transplanting donor BMSC were prepared by primary cell culture from transgenic mouse expressing luciferase (LUC). Transient focal infarcts were induced in 4-6-week-old male nude mice. The experiment mice were divided into five groups by the time of MSC transplantation : 1) sham-operation group, 2) 2-h group, 3) 1-day group, 4) 3-day group, and 5) 1- week group. BLI for detection of spatial distribution of transplanted MSC was performed by detecting emitted photons. Migration of the transplanted cells to the infarcted area was confirmed by histological examinations. Differences between groups were evaluated by paired t-test. RESULTS: A focal spot of bioluminescence was observed at the injection site on the next day after transplantation by signal intensity of bioluminescence. After 4 weeks, the mean signal intensities of 2-h, 1-day, 3-day, and 1-week group were 2.6x10(7) +/- 7.4x10(6), 6.1x10(6) +/- 1.2x10(6), 1.7x10(6) +/- 4.4x10(5), and 8.9x10(6) +/- 9.5x10(5), respectively. The 2-h group showed significantly higher signal intensity (p < 0.01). The engrafted BMSC showed around the infarct border zones on immunohistochemical examination. The counts of LUC-positive cells revealed the highest number in the 2-h group, in agreement with the results of BLI experiments (p < 0.01). CONCLUSION: In this study, the results suggested that the transplanted BMSC migrated to the infarct border zone in BLI study and the higher signal intensity of LUC-positive cells seen in 2 hrs after MSC transplantation in MCAO mouse model. In addition, noninvasive imaging in real time is an ideal method for tracking stem cell transplantation. This method can be widely applied to various research fields of cell transplantation therapy.

Spinal epidural emphysema is rare, and only a few cases have ever been reported. A 18 year-old man was admitted for neck and chest pain for 3 days. Before admission he experienced rhinorrhea and severe cough. Physical examination revealed wheezing on whole lung field and subcutaneous emphysema over the upper portion of the chest and neck. Chest radiograph showed pneumomediastinum ajdn subcutaneous emphysema in the neck and chest CT images demonstrate a free air in the prevertebral fascia. With coservative management, the patient's condition and the pneumomediastinum improved. The patient was discharged to home on the fourteenth day.

BACKGROUND: Accurate staging is important to determine treatment modalities and to predict prognosis for the patients with lung cancer. The simple two-stage system of the Veteran's Administration Lung Cancer study Group has been used for staging of small cell lung cancer(SCLC) because treatment usually consists of chemotherapy with or without radiotherapy. However, this system does not accurately reflect segregation of patients into homogenous prognostic groups. Therefore, a variety of new staging system have been proposed as more intensive treatments including either intensive radiotherapy or surgery enter clinical trials. We evaluate the prognostic importance of TNM staging, which has the advantage of providing a uniform detailed classification of tumor spread, in patients with SCLC. METHODS: The medical records of 166 patients diagnosed with SCLC between January 1989 and December 1996 were reviewed retrospectively. The influence of TNM stage on survival was analyzed in 147 patients, among 166 patients, who had complete TNM staging data. RESULTS: Three patients were classified in stage l /ll, 15 in stage llla, 78 in stage lllb and 48 in stage lV. Survival rate at 1 and 2 years for these patients were as follows stage l/ll, 75% and 37.5% ; stage llla, 46.7% and 25.0% ; stage lllb, 34.3% and 11.3% ; and stage lV, 2.6% and 0%. The 2-year survival rates for 84 patients who received chemotherapy(more than 2 cycles) with or without radiotherapy were as follows stage l/ll, 37.5% ; stage lll, 31.3% ; stage lllb 13.5% ; and stage lV 0%. Overall outcome according to TNM staging was significantly different whether or not received treatment. However, there was no significant difference between stage llla and stage lllb though median survival and 2-year survial rate were higher in stage llla than stage lllb. CONCLUSION: These results suggest that the TNM staging system may be helpful for predicting the prognosis of patients with SCLC.

OBJECTIVES: To determine the presentation, incidence, and risk factors of seizures in patients treated for brain tumors. METHODS: One hundred patients who consecutively underwent a craniotomy for the treatment of supratentorial brain tumors were assessed. The pathologies of the patients enrolled in the study included glioma (n=56), meningioma (n=31), metastatic brain tumor (n=7), primary central nervous system lymphoma (n=4), and central neurocytoma (n=2). Anti-epileptic drugs (AEDs) were administered to all patients for up to six months after the surgery. Pre-defined variables for outcome analysis included tumor grade and location, extent of tumor resection, number of seizures, age at tumor diagnosis, adjuvant therapy, medication and radiological abnormalities. RESULTS: Thirty patients (30%) presented at least a single episode of seizure at the time of admission. Five of these patients (16.7%) developed the seizure during the follow-up period. Newly developed seizure was noticed in six out of seventy patients (8.6%) without prior seizure. Histopathology was malignant gliomas in 10 and supratentorial meningioma in one. Early seizure developed only in two patients. CONCLUSION: Compared with patients without seizure, patients with seizure at the time of admission showed younger age (p=0.003), a higher portion of low-grade glioma (p=0.001), tumor location in the frontal and temporal lobes (p=0.003) and cortical involvement (p=0.017). Our study suggestes that tumor progression is considered a significant risk factor for seizure development in glioma patients.

Numerous studies have demonstrated the clinical activity of temozolomide, a second-generation alkylating agent, against malignant brain tumors, however, its activity has not been reported in an Asian population. This study analyzed the efficacy and toxicity of temozolomide in 25 adult patients with recurrent or progressive malignant gliomas after surgery and standard radiation therapy with or without chemotherapy, enrolled in our institution since July 2000. Sixteen patients had glioblastoma multiforme (GBM), six with anaplastic astrocytoma, and three with anaplastic oligodendroglioma. Of the 25 patients, 3 (12%) achieved a complete response (CR), 8 (32%) achieved a partial response (PR), 6 (24%) had stable disease (SD), and 8 (32%) had progressive disease (PD). Two patients achieved a CR, 4 patients achieved a PR, 3 patients had SD and 7 patients had PD in GBM, and 1 patient achieved a CR, 4 patients achieved a PR, 3 patients had SD, 1 patient had PD in the non-GBM patients. Median progression free survival was 8 weeks in GBM and 22 weeks in the non-GBM patients. The median overall survival of each group was 17 weeks and 28 weeks. Temozolomide demonstrated moderate activity in recurrent and progressive malignant gliomas without serious toxicity.

Primary Hyperparathyroidism is the metabolism abnormality of calcium, phosphate, and bone due to the high synthesis of parathyroid hormone, a rare endocrine disease in children. It scarcely occurs in children so that till now it was reported only 4 cases in Korea, especially with abdominal symptoms. We report this case of primary hyperparathyroidism with brief review of literatures.

PURPOSE: Lung cancer is now one of the most frequently diagnosed cancers in the world and its incidence has been increasing also in Korea. In several recent studies, the indidence of adenocarcinoma and female/male ratio have been reported to be increasing. The aim of this study is to investigate the changing trends in sex and age distribution, the histologic type and location (peripheral or central) of tumors in lung cancer. MATERIALS AND METHODS: We performed the retrospective review of histopathology and clinical information of 1409 patients diagnosed as baving primary lung cancer, except non-epithelial tumors and undetermined histologic types, at Kyungpook National University Hospital from January 1988 to December 1996. RESULTS: Male to female ratio was 4.6; 1. The peak incidence of age group was 7th decade (40.3%) with mean age of 61.5. Percentage of smokers in patients with lung cancer was 84.3%. Total number of patients with lung cancer has increased recently. However, the annual female/male ratio was nearly constant during the study period. Peripheral tumors, which were found in 20.6% of patients with lung cancer in 1988, increased to 33.5% in 1996 and this trend was more prominent in squamous cell carcinoma than in adenocarcinoma. Squamous cell carcinoma was the most common histologic type (62.0%), followed by adenocarcinoma (19.2%), small cell carcinoma (14.2%), large cell carcinoma (4.6%) in order. There was a predominance of squamous cell carcinoma (67.9%) in males and of adenocarcinoma (46.6%) in females. There has been a significant shift in the histology pattern with an increase in the percentage of adenocarcinoma. The incidence of adenocarcinoma was more than doubled from 7.5% in 1988 to 25.8% in 1996. CONCLUSION: These findings suggest that the epidemiology of lung cancer is changing.
