Ellis-Van Creveld Syndrome*

A 29 year old woman with unresectable leiomyosarcoma of the inferior vena cave extending into the right atrium of the heart was presented. The upper and middle inferior vena cava involved and there were both intrinsic and extrinsic tumor growth components. The diagnosis was made by a combination of radiological studies including ultrasound, CT, inferior vena cavography and arteriography and the diagnosis was confirmed by ultrasound guided rumor biopsy. The clinical and radiological presenting features were reviewed.

BACKGROUND AND PURPOSE: The present study was carried out to investigate transient arteriolar vasospasm following reperfusion in the gerbil as an ischemic model and relationship between vasospasm and the changes of morphologic, physiologic and regional blood flow. METHODS: The transient arteriolar vasospasm was observed under the microscope. All gerbils were perfusion fixed and ischemic neuronal damage was checked in the CA1 subfield of the dorsal hippocampus. Metabolic parameters were serially measured during the occlusion and after recirculation, and cerebral blood flow was measured with a laser Doppler flowmetry. RESULTS: 1. Among the 18 gerbils with BCAO(bilateral carotid artery occlusion) for 2 minutes, 8 gerbils showed vasospasm after reopening, namely post-ischemic vasospasm, and 10 gerbils did not show vasospasm. 2. In all animals, metabolic parameters showed decreased PaCO2 and high pH just after the occlusion but increased PaCO2 and lowered pH following the recirculation. BCAO caused marked increase in systemic blood pressure but it returned to preischemic levels following the recirculation. 3. In all animals, BCAO caused marked decrease of cerebral blood flow compared to preischemic levels immediately following the occlusion but it returned to preischemic levels following the recirculation. And it took some longer the onset and duration of the transient increase in blood volume after reopening in the animals with vasospasm than those without vasospasm. 4. There was no morphological neuronal damage in the hippocampal CA1 subfield, at 1, 3, 7 days following 2-minute ischemic insult. CONCLUSION: The present study confirmed that BCAO in gerbils resulted in forebrain ischemia caused transient cortical vasospasm in the gerbil. But there was no close relationship between vasospasm and the changes of morphologic, physiologic and regional blood flow.

Neurocutaneous melanosis is a very rare congenital syndrome characterized by the presence of large or multiple congenital melanocytic nevi and benign or malignant melanotic tumors of the central nervous system. We report herein a case of neurocutaneous melanosis with leptomeningeal melanosis and a malignant melanoma of the right temporal lobe in a 46-year old man. The case is exceptional as regards the late onset of symptoms and death. Even without a malignant melanoma, the symptomatic neurocutaneous melanosis has a fatal course. The syndrome is rare but lethal, so the dermatologist should be aware of this syndrome when evaluating the patients with large or numerous congenital melanocytic nevi so as to watch for the usual signs of increased intracranial pressure and to take prompt palliative measures.

There has not been any report on massive air-containing liver abscess in diabetic patients, although emphysematous cholecystitis or pyelonephritis is a well-known complication in them. Authors report two cases of emphysematous liver abscess in diabetic patient, which showed typical findings of massive air-containing hepatic abscess on ultrasonography and computed tomography, but very poor progrosis in spite of immediate and successful percutanoeus drainage procedure.

Cancer incidence has been increasing steadily and is the leading cause of mortality worldwide. Gastric cancer is still most common malignancy in Korea. Cancer initiation and progression are multistep processes involving various growth factors and their ligands. Among these growth factors, we have studied hepatocyte growth factor (HGF), which is associated with cell proliferation and invasion, leading to cancer and metastasis, especially in gastric cancer. We explored the intercellular communication between HGF and other surface membrane receptors in gastric cancer cell lines. Using complimentary deoxyribonucleic acid microarray technology, we found new genes associated with HGF in the stomach cancer cell lines, NUGC-3 and MKN-28, and identified their function within the HGF pathway. The HGF/N-methyl-N’-nitroso-guanidine human osteosarcoma transforming gene (c-MET) axis interacts with several molecules including E-cadherin, urokinase plasminogen activator, KiSS-1, Jun B, and lipocalin-2. This pathway may affect cell invasion and metastasis or cell apoptosis and is therefore associated with tumorigenesis and metastasis in gastric cancer.

Pulmonary blastoma is a rare lung tumor resembling fetal lung tissue. Pathologically the tumor can be classified to 2 groups, well-differentiated fetal adenocarcinoma(WDFA) and biphasic blastoma. WDFA has more favorable prognosis with fewer metastasis at initial presentation and fewer recurrence after treatment. We experienced a case of pulmonary blastoma in 32-year-old female patient. The patient was referred to our hospital because of abnormal mass shadow in right middle lobe. The diagnosis of pulmonary blastoma(WDFA type, Stage I T2NOMO) was confirmed after right middle lobectomy. We followed up 22 months without an evidence of recurrence.

PURPOSE: The purpose of this study was to describe the experience of hospice nurses on spiritual care. METHODS: Data was collected from 9 hospice nurses by using in-depth interview. The main questions include what they understand as spiritual care, when they feel the needs of spiritual care, how they perform spiritual care, and what is the outcome of spiritual care. The data was analyzed by grounded theory methodology developed by Strauss and Corbin. RESULTS: The core category of experience of hospice nurses on spiritual care was identified as "Untie a knot of mind". In the process of spiritual care in hospice nurses was consisted of soothing, dwelling with, releasing, giving meaning, plunging, and going beyond a life. CONCLUSION: The result of this study was expected to give useful information to nurses and nursing managers about the real situation of performance of spiritual care. The findings of this study contributes to developing programs and supportive policies for encouraging spiritual care.
